Obturator dislocation of the hip with ipsilateral femoral neck fracture: A case report

Obturator dislocation of the hip associated with ipsilateral femoral neck fracture is an unusual injury. We report a case of a 40-year-old man with such a combination of injuries which was treated with an open reduction and internal fixation. He has a good follow-up result. There was no evidence of avascular necrosis on radiographs after 3 years.     

Anterior dislocation of hip with ipsilateral femoral neck and head fracture

A 70-year-old male patient presented to our emergency department with trauma left hip following a fall. Physical examination revealed external rotation, slight flexion, adduction, and shortening of the affected limb. There was a palpable fullness in the groin. Radiographic examination revealed fracture neck of femur with femoral head dislocated anteriorly and lying in the obturator foramen. There was an associated femoral head fracture with a fragment of it in the acetabulum. Although this sort of injury has been reported once, the difference in our case lies in the age of the patient; the injury complex was caused by a less severe trauma and a unique mechanism of injury. Also a modification of Brumback classification is proposed to include such fractures more specifically in order to allow comparative analysis in such rare injuries as more and more such case reports are added to literature.     

Posterior dislocation of the hip with concomitant ipsilateral fractures of both the femoral head and shaft: A case report

Summary we report a rare injury in a 32-year-old man victim of a high-energy motor vehicle accident who sustained a posterior hip dislocation with concomitant ipsilateral fractures of both the femoral head and femoral shaft. Closed reduction of the hip was attempted but failed. Surgical approach was necessary to reduce the hip and then femoral nailing was performed. The femoral head fragment was neglected. The patient died after 2 days of neurological complications. Combination of posterior hip dislocation with ipsilateral femoral shaft and head fractures is unusual.     

Traumatic hip dislocation with ipsilateral femoral shaft fractures

A traumatic dislocation of the hip joint associated with an ipsilateral femoral shaft fracture is a rare injury resulting from severe trauma. Initially the dislocated hip joint is often unrecognized and consequently reduction is delayed. Early diagnosis and reduction of the hip joint improves the functional prognosis. The maximum functional recovery is possible only with greater awareness of this combined injury. Examination of the hip joints by clinical roentgenography in the critically injured patient, especially those with head injuries, or physical signs masked by extremity swelling, should be a routine procedure.     

Concomitant fractures of the femoral head and neck without hip dislocation

This case report describes two patients who sustained ipsilateral fractures of the femoral head and femoral neck without dislocation of the hip. The fractures in the two patients resulted from vehicle accidents. The femoral head was fractured in the sagittal plane, and the femoral neck was fractured at the subcapital portion. However, the hip was not dislocated in either patient. Both patients were treated using cementless total hip arthroplasty. These unusual hip injuries have not been reported previously and are not categorized according to any known classification system of hip injuries.     

Traumatic anterior dislocation of the hip associated with ipsilateral femoral neck fracture: a case report

A thirty-nine-year-old female patient was brought to the emergency room following an automobile accident. Radiographic examination revealed a subcapital fracture of the left femur associated with anterior femoral head dislocation, and a contralateral comminuted femoral shaft fracture. Computed tomography showed that the acetabulum was empty, with the femoral head dislocated anteriorly close to the obturator foramen. Uncemented total hip arthroplasty and locked intramedullary nailing were performed on the left and right sides, respectively. Sixty-two months after surgery, she had no difficulty in performing daily activities.     

Posterior dislocation of the hip with ipsilateral displaced femoral neck fracture

Traumatic posterior dislocation of hip associated with ipsilateral displaced femoral neck fracture is a rare injury. Moreover, the management of such patients evokes strong views regarding primary replacement or preserving the femoral head. We presented a case of young adult with such an injury. He was operated upon with reduction of the dislocation and fixation of femoral neck fracture with the help of cancellous screws. Two years later, the fracture had united and the patient was asymptomatic. We further proposed the mechanism of injury for such a fracture and discussed the management in the changing trauma scenario of the developing world.     

Anterior perineal dislocation of the hip with fracture of the femoral head. A case report

Traumatic anterior perineal hip dislocation with an associated fracture of the femoral head is a rare entity. A 26-year-old man injured in a motorcycle accident was treated by closed reduction of the dislocation within three hours after admission. However, several reports of patients with anterior hip dislocation with associated femoral head fractures were treated nonoperatively and had unfavorable results when treatment failed to achieve anatomical position of the fragments. Consequently, this patient was treated by open reduction and internal fixation of the fractured fragment. Follow-up examination three and one-half years after the operation showed painless functional range of hip motion with only minimal discomfort after prolonged exertion.

Central fracture dislocation of the hip associated with fracture of femoral neck treated by femoral head autograft and total hip arthroplasty: A rare case report

Central Fracture Dislocation of the Hip is a rare condition requiring more attention in its management, caused by high-energy trauma and is often associated with other injuries. This case report presents a 57-years old female who was injured in a traffic accident and diagnosed with polytrauma, abdominal blunt trauma with 7th zone liver laceration, central fracture dislocation of the left hip associated with closed fracture left acetabulum anterior column and closed fracture left neck femur. Until now, there is no mandatory management to treat this kind of injury. Several surgical techniques were explained in previous literatures to treat this condition such as Open Reduction and Internal Fixation (ORIF) procedure and Total Hip Arthroplasty (THA). Some studies chose THA as a treatment for similar condition in older population due to high risk of nonunion and avascular necrosis of the femoral head, especially in cases of significant displacement and devitalization of the femoral head. In this case, we performed femoral head autograft and total hip arthroplasty as a definitive treatment.     

Posterior fracture dislocation of the hip with fractures of the femoral head

In general, all traumatic dislocations of the hip must be treated as surgical emergencies. Multiple attempts at closed reduction are contraindicated, particularly in Type V dislocations. Every effort must be made to recognize the dislocation, particularly in patients with other severe lower extremity trauma. Reduction within 24 hours gives better results than late reductions. Roentgenograms of the pelvis must include both hips after closed or open procedures as a check for a concentric reduction of the hip. Any abnormality, or failure to reduce the avulsed head fragment, demands an immediate hip arthrotomy. The good results, after primary open reduction, although under 50%, were better than closed or closed followed by open reduction. Our approach is to discard the avulsed head fragment. No conclusions can be made regarding screw fixation of the avulsed fragment because there was an insufficient follow-up period in this procedure. Long-term follow-up examination is necessary in Type V fracture dislocations because one can anticipate that arthritic changes will develop in more than 50% of patients. Anterior approaches to excise head fragments in Type V dislocations are contraindicated. Early intervention is indicated in all dislocations with sciatic or peroneal nerve paralysis. Because most dislocations in this series were due to automobile accidents, the routine use of seat belts could have prevented many of these injuries.     

Fracture of the femoral head without dislocation. A case report

Fracture of the femoral head without dislocation of the hip sustained in a traffic accident and diagnosed by computed tomography is reported. The authors are not aware of similar reports.     

Direction of hip arthroplasty dislocation in patients with femoral neck fractures

In order to prevent hip arthroplasty dislocations, information regarding the direction of the dislocation is important for accurate implant positioning and for optimising the postoperative regimens in relation to the surgical approach used. The aim of this study was to analyse the influence of the surgical approach on the direction of the dislocation in patients treated by a hemiarthroplasty (HA) or total hip arthroplasty (THA) after a femoral neck fracture. Fracture patients have a high risk for dislocations, and this issue has not been previously studied in a selected group of patients with a femoral neck fracture. We analysed the radiographs of the primary dislocation in 74 patients who had sustained a dislocation of their HA (n = 42) or THA (n = 32). In 42 patients an anterolateral (AL) surgical approach was used and in 32 a posterolateral (PL). The surgical approach significantly influenced the direction of dislocation in patients treated with HA (p < 0.001), while no such correlation was found after THA (p = 0.388). For THA patients there was a correlation between the mean angle of anteversion of the acetabular component and the direction of dislocation when comparing patients with anterior and posterior dislocations (p = 0.027). These results suggest that the surgical approach of a HA has an influence on the direction of dislocation, in contrast to THA where the position of the acetabular component seems to be of importance for the direction of dislocation in patients with femoral neck fractures.     

Unusual displacement of the femoral head in anterior traumatic dislocation of the hip. A case report

An unusual case of anterior traumatic hip dislocation which occurred in a thirty-three-year-old man is described. The femur had a 90 degree anterior rotation while the femoral head was exactly at the same level as when normal. The best term suited for this type of dislocation is "intermediate" or "inguinal" because the femoral head was dislocated anteriorly but remained at the normal level.
