Traumatic Hip Dislocation: Lecture
Abstract
Traumatic hip dislocations occupy the fourth place among dislocations of various localizations and, as a rule, are the result of exposure to a high-energy traumatic agent. Such injuries are more often observed in young and middle-aged males. The main cause of hip dislocations is road accidents. The femoral head is more often dislocated posteriorly, but anterior dislocations are not casuistic and account for approximately 10%. Hip dislocations are often combined with acetabular fractures, while their fairly clear clinical picture in the presence of fractures can be leveled. Traumatic hip dislocations require urgent diagnosis and treatment. After the clinical examination of the patient, an x-ray of the pelvis and hip joints are performed. Radiographic diagnosis of hip dislocation remains relevant, but modern imaging methods allows to study the hip joint in more detail and identify concomitant injuries. The main treatment for hip dislocation is closed reduction. Early dislocation reduction and the absence of damage to the structures forming the hip joint are important for the treatment results prognosis. The further patient management tactics after the dislocation reduction is determined by the results of stress tests and the CT data. When confirming the instability and associated injuries of the hip joint anatomical structures, surgical treatment is indicated. Among the complications of hip dislocation: sciatic nerve damage, post-traumatic coxarthrosis, the femoral head avascular necrosis, heterotopic ossification. Current literature data indicates the importance of early diagnosis of dislocation-associated injuries of the hip joint and periarticular tissues. Early and comprehensive repair of all existing injuries is crucial for favorable outcomes. A number of therapeutic and diagnostic methods, primarily arthroscopy, show optimistic results, but need further study.
