erate abduction of the right and left shoulders, forearms bent in the elbow joints, are in a position on the chest, middle between supination and pronation, hands in the middle position, fingers are half-bent when the S7 vertebra is affected.
Free flexion and extension of the hand in the wrist joint indicates the integrity of the S7 vertebra. The preservation of movements in the fingers (function of the muscles of the flexors and extensors of the fingers) indicates the absence of damage to the S7 root.
When examining the thoracic and lumbar regions, attention is paid to the pres­ence or absence of kyphotic deformation. Its degree can be so little expressed that it is captured only by the experienced eye of a specialist.
In the lumbar region, it manifests itself by smoothing physiological lordosis, against the background of which in people of asthenic physique the spinous process is visible in the form of a button. Often, this persistence of the spinous process of the damaged vertebra is determined only palpatorally. In addition to deformation of the spine in the sagittal plane, there may be a lateral curvature of the line of spinous pro­cesses indicating the presence of lateral compression of the vertebral body.
Palpation is given importance. It reveals tension of the long muscles of the back, local tenderness, swelling along the line of the spinous processes, the persis­tence of the spinous process posteriorly in the form of a "button" kyphosis, mobility at the fracture of the spinous process or the borderline sympathetic trunk, while the tension of the anterior abdominal wall occurs and the picture of a closed abdominal injury.
Percussion. The percussion of the spinous processes allows you to refine the palpation data. Significant tenderness caused by percussion along the line of the spi­nous processes, in the absence of pain during palpation, can indicate damage to the vertebral body with great confidence. Percussion in fractures complicated by spinal cord damage can lead to dislocation of fragments and additional secondary spinal cord damage. In these cases, it is better to abandon percussion.
With uncomplicated spinal injuries, active movements in the limbs are pre­served. If you invite the victim to raise straight legs from the lying position, the pa­tient may note an increase in back pain. They will intensify more sharply when rais­ing straight legs with simultaneous pressure on the spinous process of a broken or protruding overlying vertebra.
Of other clinical symptoms, reflex urinary retention, stool retention, and intes­tinal paresis may occur. Sometimes they persist for 1 week and require close attention of the attending physician. It is necessary to always remember the danger of checking symptoms such as determining the volume of movements in the spine, identifying Thompson's symptom (increased spinal pain at the level of damage in the sitting posi-
62
tion and a significant decrease in them when unloading the spine with the victim's hands resting against the seat of a chair or couch).
The phenomenon of increased pain during load along the axis of the spine should not be detected even in the lying position. Only easy swinging on the heels is allowed. It is impossible to allow the patient to get up or sit down until the X-ray data are obtained.
Impaired spinal cord function in fractures.
Impaired spinal cord function in spinal fractures depends on concussion, contu­sion, compression, swelling, partial or complete anatomical damage to the spinal cord, damage to its roots. Compression of the spinal cord can be front, back and side. In the front, it is most often caused by a hematoma, bone fragments of a broken or dislocated posteriorly edge of the body of the underlying vertebra by fragments of a torn intervertebral disc. Compression is much less common behind and is caused by an arc of a dislocated vertebra or its fragments, a yellow ligament, and a hematoma. Lateral compression occurs by the articular processes and the adjacent other struc­tures of the spinal segment, depending on the mechanism of injury and the displace­ment of the broken vertebra or its fragments. In the first hours and days after the inju­ry, it is difficult to resolve the issue of the cause of gross impairment of spinal cord function, since the clinic in severe spinal shock (functional disorders) practically does not differ from the clinic in complete anatomical damage.
The rapid increase in neurodystrophic processes, the appearance of pressure sores and edema of soft tissues in the first day after injury indicate in favor of ana­tomical rupture. With complete ruptures of the spinal cord, its function is never re­stored. The violation of spinal cord function caused by compression by bone frag­ments occurs if the dislocation was corrected in a timely manner, the fracture, and, if necessary, the fragments were removed. The clinic of spinal disorders associated with concussion, contusion, compression of the spinal cord by supra and sub-enveloped hemorrhages, its edema, gradually regresses. Partial conduction of the spinal cord is manifested by impaired sensitivity in the conductor type below the level of damage, paresis, paralysis and pelvic organ function disorder.
Pelvic injuries.
Pelvic and pelvic injuries belong to the group of the most severe injuries of the musculoskeletal system. With each decade they become difficult, the specific gravity of open and combined injuries increases. According to statistics from the authors of the second half of the XIX century, pelvic injuries were 0.3 to 1 % of all fractures. According to modern authors, pelvic injuries range from 5 to 10 % in relation to the total number of injuries, and in some regions up to 15 %
63
Pelvic instability.
The nature and severity of the pelvic injury, in addition to the mechanism of the injury, is assessed by the degree and nature of stability of the pelvic ring. Its sta­bility should be understood as the ability of the bones of the pelvis and its compounds to withstand ordinary physiological loads (body weight, running, jumping, walking, physical work) without pain syndrome and pathological displacements. The latter are diagnosed clinically and radiologically. The diagnostic stability criterion is consid­ered to be an indicator of the amplitude of movement in the sacroiliac joints and pu­bic symphysis within 1–3 mm under the influence of physical violence that does not cause their damage. The criterion for pelvic ring instability is the ligament of the sa­croiliac junction, so pelvic instability depends more on damage to the ligaments and bones of the posterior semicircle and less on the anterior semicircle.
There are rotary or horizontal and vertical instability. With rotational instabil­ity, horizontal rotational instability is distinguished with rotation of the corresponding half of the pelvis outward by the type of open book or inside by the type of closed book” with upward displacement (vertical instability) or without upward displa- cement.
Clinical diagnosis of pelvic injuries. To obtain an approximate idea of the presence of pelvic damage, a history with clarification of the circumstances and mechanism of injury, appearance, general condition and posture of the patient is of great importance. Familiarity with the mechanism of injury is often crucial in the first orientation. Inspection of the victim is carried out in order to diagnose damage. The passive position of the patient, he is, as it were, chained to the bed, localization and type of wound, increase in volume in the pelvis, violation of the axis of the limb segment, unusual position of the leg in the external or internal rotation and, finally, asymmetry of the pelvis are the main guidelines for examination.
An attempt at movement in the lower limb causes sharp pain in the pelvic ring.
Inspection of the pelvic region is advantageous both from the side and from the front to compare both halves of the pelvis. Severe pelvic fractures with type shift Malgen can always be suspected by the presence of pelvic asymmetry, the displace­ment of the navel from the midline, the reversal of one half of it and the external rota­tion of the leg of the same side.
With bilateral fractures of Malgen, a kind of flattening of the pelvis is visible a significant expansion of its diameter. Typical is the typical position of the victim. When the symphysis ruptures, both legs are bent in the knee joints and are given; the victim does not allow them to dilute due to the appearance of severe pain in the projection of the pubic joint. With a fracture of both pubic and ischial bones, as well as with vertical fractures of Malgen, the position of Volkovich, or frog, is
64
characteristic (a symptom of Volkovich, 1928). In this position, the legs of the victim are bent in the knee and hip joints and divorced. They resemble the shape of a rhom­bus or a preparation of frog paws. On the 2nd day, bruises may appear in the sur­rounding tissues, with a fracture localizing closer to the iliac bone over the umbili­cal ligament, with a fracture of the descending branch of the pubic and ischial bones in the perineum.
In a tear fracture of the anterior upper axis of the iliac bone, the victim moves his back forward, and not his face (a symptom of reverse, or Lozinsky, 1928), since the sartorial muscle (m. sartonus) starts from the anterior superior spine of the ilium and attaches to the anterior-copper-calf surface in the tuberositas tibia region. When bending the thigh and lower leg when walking face forward, the muscle tightens, causing a displacement of the fragment of the anterior superior spine of the iliac bone, the patient sharply increases pain syndrome.
With a fracture of the horizontal branch of the pubic bone, the patient, being in a horizontal position, cannot raise the corresponding leg in the extension position, cannot tear the heel from the bed, but the passively raised limb holds independently without assistance a symptom of a stuck heel, or a symptom of Gorinevskaya.
Scallop muscle (m. pectineus) starts from the crest of the horizontal branch of the pubic bone (rames superior et pecten ossis pubis) and, heading down and slightly outward, attaches to the scalloped line (linea pectinea) of the thigh distal to the lesser trochanter. The muscle flexes and brings the thigh, slightly rotating it outward. When trying to raise the leg on the side of the damage to the pelvis, the muscles tighten, in­creasing the pain syndrome.
To diagnose pelvic fracture in the absence of traumatic shock, a number of symptoms can be identified:
1) Verneil's symptom increased pain with careful oncoming external com-
pression of the pelvis in the area of the wings of the iliac bones;
2) Larrey's symptom increased pain in the area of pelvic damage during di-
lution or reversal of the wings of the iliac bones;
3) Sgaddart's symptom the appearance or increase of pain in the sacroiliac
joint during the mixing and dilution of the iliac bones;
4) symptom of A.N. Karalin appearance or increase of pain in internal hip
rotation.
Palpation. Local tenderness in the fracture area can be detected during palpa­tion in the areas of the osteae or ridges of the iliac bones, pubic articulation, ischial bones. When symphysis is broken, palpation determines diastasis and its value be­tween the bones in the area of the pubic junction. In case of violation of the integrity of the pelvic ring, the mobility of bone fragments occurs even with the slightest
65
movements of the victim's legs, and non-cutting palpation during examination can aggravate the patient's condition.
Symptom Mouse shortening the distance from the xiphoid process or navel to the anteroposterior spine of the iliac bone on the damaged side. With an isolated fracture of the upper anterior spine of the iliac bone with a downward displacement of the fragment, an apparent shortening can be detected.
Symptom Ru shortening the distance from the upper anterior spine to the pubic joint; indicates a fracture of the pubic bones with dislocation of fragments.
Bejul's symptom shortening of the distance from the sternoclavicular joint to the anteroposterior spine of the ilium on the damaged side.
Palpatory examination should be supplemented by careful rectal and vaginal examination. In this case, a fracture of the coccyx, sacrum, pubic bones, the bottom of the acetabulum and the head of the femur embedded in the pelvic cavity can be de­tected. If the rectum ruptures, the finger may fall into the wound, and the surgeon's glove will contain blood. With vaginal examination, it is also possible to determine the displaced fragments of the pubic, ischial bones, the bottom of the acetabulum and the presence of damage to the vaginal mucosa. If vaginal or rectal damage is detect­ed, an open communicating (penetrating) pelvic fracture should be diagnosed.
In an acetabulum fracture, A.P. Nadein in 1939 described the main symptoms:
1) hip is in the position of reduction, easy flexion and external rotation;
2) significant limitation of movement and sharp soreness in passive and active
movements in the damaged joint;
3) tenderness along the obturator nerve and irradiation of pain to the knee joint;
4) restriction or complete impossibility of hip abduction;
5) the presence of a hematoma in the area of the greater trochanter, the umbili-
cal ligament and the Scarp triangle;
6) tenderness during lateral compression of the pelvis in the area of the large
trochanter, load along the thigh axis or on the large trochanter along the axis of the neck on the side of damage to the acetabulum;
7) reducing the distance between symphysis and the large femoral trochanter
on the injury side;
8) relative shortening of the lower limb on the corresponding side;
9) the upper edge of the large spit is located above the Roser Nelaton line;
10) subsidence in the greater trochanter area in central hip dislocation;
11) determination of femoral head protrusion in pelvic cavity at rectal and vag-
inal examination.

The severity of damage and traumatic shock directly proportionally increases with multiple, combined injury with damage to the pelvic organs, abdominal cavity and chest, the size of blood loss. According to literary data, traumatic shock occurs in
40.2–93.1 %, and with polytrauma — in 60–100 % of injured. Stopped bleeding can resume with the most insignificant movements of the patient: shifting, insufficiently careful transportation of the victim from the scene or in a medical institution from one structural unit (emergency room, operating room, intensive care unit) to others, insufficiently careful research.
Hematoma in the retroperitoneal space can spread to the level of the kidneys and diaphragm, and in front to the level of the umbilical horizontal. Hematoma through the obturator canal can spread to the lower third of the thigh down. In this case, the intestines and kidneys are displaced inside and to the anterior abdominal wall. It should be especially remembered that the severity of shock depends not so much on the amount of lost blood as on the rate of bleeding, since with rapid massive blood loss in the body they do not have time to react and develop compensatory mechanisms (transition of interstitial fluid into the vascular channel, tachycardia, spasm of peripheral vessels, centralization of blood circulation).
Traumatologists and surgeons with resuscitation anesthesiologists may not have time to provide the necessary effective assistance. Injured by the time of admis­sion to the medical institution lose from 2–3 to 3–4 liters of blood. With large hema­toma sizes, blood from the retroperitoneal space can enter the free abdominal cavity even with an intact peritoneum in a diapedetic way from a small amount to 2 liters. A massive retroperitoneal hematoma with ongoing bleeding can be accompanied by a rupture of the peritoneum and the penetration of whole blood into the abdominal cavity. The literature suggests that bleeding in pelvic fractures can last from 2 to 5 days or more. One of the reasons for the severity of traumatic shock and aggrava­tion of the general condition of the victim is damage to the bladder of the urethra, rec­tum and extremely rarely the vagina, uterus and appendages.
Damage to the urinary organs is diagnosed with fractures of the pelvic bones in 10–28 % of cases in adults and in 7–8 % in children. Most often, damage to the uri­nary organs occurs when the front is hit or compressed with scrolling. Any pelvic in­jury should therefore be considered as complicated until the absence of urinary tract damage is proven or confirmed. The presence of blood in the urine is an important diagnostic test, but not reliable for damage to the bladder or urethra. Blood can be ob­served with damage to the kidneys, ureters, thawing of the muscle layers of the pelvic floor, hematoma of the bladder wall.
The subjective early sign of bladder damage is pain in the lower abdomen, above the bony joint. In case of intraperitoneal rupture, the pain is taken to be spilled,
67
intensified when strained in order to attempt spontaneous urination. Pains are irradi­ated into the navel area, the head of the penis, the rectum, sometimes into the thigh area. Impaired urination manifests itself as a complete absence of urine discharge. There is a gradual increasing tension of the anterior abdominal wall with symptoms of irritation of the peritoneum, intestinal paresis.
Change of position the victim, leading to the movement of urine poured into the abdominal cavity, causes an increase in abdominal pain and the patient's re­sistance to all movements (a positive symptom of vanka-standing).
Bladder catheterization is used for diagnosis. When the catheter is inserted, a small amount of urine is released at once, but it is worth moving the catheter further so that it gets through the bladder wound into the abdominal cavity, then up to 2 liters of urine will be released, which confirms the intraperitoneal rupture of the bladder. In doubtful cases, the bladder is emptied using a catheter, then 250–300 ml of furacilin is introduced and the catheter is pressed. After a few minutes, the catheter is opened and the contents are removed. If its contents significantly exceed the amount of fura­cilin injected, it can be assumed that fluid flows out of the abdominal cavity (Zeldo- vich's symptom).
In the case of late diagnosis with intraperitoneal ruptures of the bladder, a clin­ic of purulent peritonitis develops. With extra-abdominal ruptures of the bladder, the lateral, anterior, posterior walls that are not covered with the peritoneum are dam­aged, or a complete detachment of the bladder in the area of its neck occurs. The pos­terior wall of the bladder is most often damaged, where the lower cystic arteries and veins pass. Patients complain of pain in the lower abdomen above the pubis, fre­quent urge to urinate. It is possible in a weak stream, in small portions, urine is stained with blood. With palpation soreness over the pubis, sometimes there can be tension of the anterior abdominal wall. Percutory blunting extends to one or both inguinal areas. It does not decrease during catheterization, and its boundaries do not change when the victim turns. Palpation through the rectum reveals painful tissue infiltration.
Later, swelling appears in the area of the pelvis, perineum, thigh with the for­mation of urinary fistulas, the development of pelvic phlegmon and osteomyelitis. In the future, general intoxication increases, manifested in the form of dry tongue, skin, tachycardia, BP fall and deterioration of general condition.
Urethral damage.
Urethral damage is characterized by urinary retention, blood excretion from the urethra, perineal hematoma and complaints of patients about cutting pains in the peri­neum area, which increase during each attempt to urinate, blood excretion from the urethra, urinary incisors, infertile urges to it, and delayed urinary discharge. With ure-
68
thral damage, initial blood staining of urine is always noted. Its staining intensity will vary. It will be more intense when the membranous part of the urethra breaks and less pronounced when the prostatic part is damaged. The manifestation of perineal hema­toma during the first 3 hours is characteristic of damage to the urethra, later it can be with symphysis ruptures and fractures of the anterior half-ring of the pelvic bones. The latter reduces the value of this symptom. Urine released from the damaged ure­thra impregnates the surrounding fiber and forms urinary weeds.
Rectal ruptures occur with fractures of the pelvic bones much less often. Dis­tinguish between extraperitoneal and intraperitoneal injuries of the rectum. Extraperi­toneal injuries are manifested by the development of severe pelvic phlegmon. Intra­peritoneal ruptures are characterized by rapidly developing symptoms of peritonitis. To exclude rectal pathology, rectal examination should be performed on all injured with pelvic injury. Thus, with fractures of the pelvic bones, it is important to diagnose not only the pelvic bones, but also the internal organs of the abdominal cavity and pelvis, especially the rectum and bladder.
Head injuries.
Head injuries are some of the most severe injuries that injured can suffer from accidents. Very often, they (especially injuries to the scalp) are accompanied by sig­nificant bleeding, which can threaten the life of the victim at the scene. If a person is unconscious, then he should be given a stable lateral position, which reduces the like­lihood of tongue sinking and minimizes the possibility of vomiting masses or blood entering the respiratory tract. In the presence of a wound and bleeding, it is necessary to perform direct pressure on the wound, if necessary, apply a bandage. If the victim shows signs of violation of the integrity of the skull bones, it is required to cover the wound edges with bandages and only after that apply a bandage.
When a foreign object is in the wound, you need to fix it by covering it with napkins or bandages and apply a bandage. It is forbidden to remove a foreign object. Bleeding with injuries to the scalp is usually very abundant and cannot stop on its own. To stop bleeding from the scalp, it is necessary to perform direct pressure on the wound and apply a pressing bandage. Head injuries are often accompanied by im­paired brain function. Traumatic brain injury is characterized by pallor, general weakness, drowsiness, headache, dizziness and loss of consciousness.
The victim may be conscious, but not remember the circumstances of the inju­ry and the events preceding it. More severe brain damage is accompanied by pro­longed loss of consciousness, paralysis of the limbs. Fractures of the bones of the skull can be accompanied, in addition, by the following signs: the release of colorless or bloody fluid from the ears, nose; bruising around the eyes. In the process of providing first aid to the victim, he should conduct a physical and instrumental exam-
69
ination, determine the nature of all injuries, provide emergency medical care at the prehospital stage and deliver the patient to the duty specialized hospital.
Traumatic brain injury (TBI) — damage to the skull, brain, meninges, ves- sels and/or craniocerebral nerves, accompanied by clinical symptoms and in most cases morphological changes. The presence of a clear traumatic history is extremely important.
Mild TBI (LTBI) is an acute impairment of brain function, which is the result of traumatic effects, in which short-term loss of consciousness (up to 30 minutes) and/or amnesia (up to 24 hours) can be noted. It includes two nosologies: a concus­sion and a mild brain contusion.
Concussion (SGM) is the mildest clinical form of diffuse transient brain dam­age. The disorders are based on metabolic, ionic, neurotransmitter disorders and neu­roinflammation, characterized by the absence of visible changes on CT. LTBI domi­nates the structure of traumatic brain injuries — 60–95 % of all injured. The preva­lence ratio of LCBI to severe is 22:1. The ratio of concussion and contusion of light severity is approximately 4:1. Mortality in LCTI is low (0.04–0.29 %) and is almost exclusively caused by intracranial hematomas. The causes of LTBI in the population are both road accidents and domestic, criminal, sports and industrial injuries.
According to clinical forms, the following are distinguished:
1) concussion;
2) mild brain contusion;
3) moderate brain contusion;
4) severe brain contusion;
5) diffuse axonal injury;
6) compression of the brain;
7) head compression.
Following the course of traumatic brain disease, periods are distinguished:
acute;
intermediate;
distant.
An acute period is a period of time from the moment of the damaging effect of mechanical energy on the brain with a sudden disorder of its integrative-regulatory and local functions to stabilization at one level or another of impaired general and corporate functions or death of the victim. The time duration of the acute period is from 2 to 10 weeks, depending on the clinical form of TBI. Approximate periods of acute TBI in concussion — up to 2 weeks, mild brain contusion — up to 3 weeks, medium-severe brain contusion — up to 4–5 weeks, severe brain contusion — up to 6–8 weeks, diffuse axonal damage — up to 8–10 weeks, brain compression — 3–10 weeks (depending on background).
70
The interim period is the period of time from the stabilization of the corpo­rate, cerebral, focal functions disturbed by the injury to their full or partial restoration or sustainable compensation. The time duration of the intermediate period: with LCTI up to 2 months, with moderate TBI up to 4 months, with severe TBI up to 6 months.
The long-term period is the period of clinical recovery, or the maximum achievable rehabilitation of impaired functions, or the occurrence and/or progression of new pathological conditions due to TBI. The time length of the distant period: with clinical recovery up to 2 years, with a complicated course is not limited. The dura­tion of post-traumatic (or anterograde) amnesia is one of the prognostic characteris­tics of the course of concussion.
Studies show that the outcome of LCTI and the duration of temporary disabil­ity are more determined by the duration of post-traumatic amnesia compared to the assessment of the level of consciousness by ShH. In the case of post-traumatic amne­sia less than 24 hours, 100 % of patients have a good recovery (on the Glasgow out­come scale).
Physical examination. When examining the head, it is recommended to identi­fy signs indicating the fact of an injury (bruises, abrasions, wounds) and a fracture of the bones of the base of the skull with a brain contusion (bruising in the mastoid pro­cess, periorbital hematomas, fluid leakage from the external ear canal, nose, mouth). In neurological status, fine-muscular nystagmus (40 %), non-tubular anisoreflexion of tendon and skin reflexes (20 %), static ataxia (20 %), dynamic ataxia (10 %), in­creased tendon reflexes (20 %), mild sheath symptoms (10 %), disappearing in 90 % of patients during the first 4–5 days. There is no damage to the bones of the skull. The general condition of the injured usually improves significantly during the first, less often the second week.
The regression periods of clinical symptoms in the vast majority of injured with concussion are on average 4–5 days, and the periods of temporary disability usually do not exceed two weeks. With prolonged preservation of symptoms and complaints (more than 7 days), additional examination and clarification of the causes are necessary. The regression time of neurological symptoms of mild brain contusion with an untied history is usually 7–14 days, and temporary disability — up to 3 weeks.
To verify post-concussion syndrome according to the ICD-10 criteria, the di­agnosis of this condition requires a condition that arose after a head injury with three symptoms from the following group:
headache;
dizziness;
rapid fatigue;
