“…28 On the contrary, some authors support that the likeliness for development of osteonecrosis is related to the direct impact of the injury rather than the duration for reduction. 30,31 Other factors that may compromise the blood supply of the femoral head include direction of dislocation, grade of dislocation, age of the patient, and the presence of associated injuries such as fracture of the acetabulum. 32,33 In our series, only one patient had osteonecrosis of the femoral head.…”

“…Although avascular necrosis of the femoral head, is generally thought to occur within 2 years after hip dislocation, a recent report noted avascular necrosis of the femoral head, of the femoral head 8 years after a posterior hip dislocation [10]. However, recent studies suggest that avascular necrosis results from the initial injury not from a prolonged dislocation though prompt reduction is still vital [14].…”

“…Factors which influence the outcome include the extent of other severe injuries, the time of reduction which should be within 6 hours post-traumatic, the direction of the dislocation, and the overall condition of the patient prior to dislocation [2] [14]. Its prognosis depends on the initial injury and subsequent treatments.…”

Traumatic dislocation of the hip is quite rare and accounts for 2%-5% of all dislocations. We report on a case of a bilateral posterior hip dislocation associated with symmetric acetabular fracture and two cases of infracotyloid dislocation. The report included 2 men and one woman. The mean age of patients was 33 years. All dislocations followed a road traffic accident. Non-operative closed reduction was achieved within 19 hours of admission. The average follow-up time was 15 months. The hips were stable, mobile, and painless; and there was no radiographic sign of avascular necrosis of the femoral head.

“…Dislocations of the hip are high-energy injuries, with the potential for joint degeneration and long-term disability. 1 The results following dislocation depend not only on the initial energy of the violence but also on the timing of reduction and the presence or absence of associated fracture. 2 – 4 Many injuries which appear as simple dislocations may in fact be fracture-dislocations, with the fracture fragments not being easily visualized in the initial radiographs either due to the poor quality of the trauma films or because the small osteocartilaginous fracture fragments are not easily visible in the X-ray.…”

“… 5 6 These fragments may be entrapped within the joint space following reduction and may accelerate the degenerative process. 1 2 5 – 7 Routine postreduction CT scans have shown that in a large number of cases there are intra-articular loose bodies. 4 8 9 Entrapment of these loose bodies can be identified in the immediate postreduction period as they may present as incongruent reduction in the immediate postreduction films.…”

Background:Intra-articular loose bodies following simple dislocations can lead to early degeneration. Nonconcentric reduction may indicate retained loose bodies and offer a method to identify patients requiring exploration so that this undesirable outcome can be avoided.Materials and Methods:One hundred and seventeen consecutive simple dislocations of the hip presenting to the hospital from January 2000 to June 2006 were assessed for congruency after reduction by fluoroscopic assessment of passive motion in the operating room as well as with good quality radiographs. Computerized tomography (CT) scan with 2-mm cuts was done for confirmation of reduction and to identify the anatomy of loose bodies. Patients with nonconcentric reduction underwent open exploration to identify the etiology of the dislocation and for removal of loose bodies. Thomson and Epstein clinical and radiological criteria were used to assess the outcome.Results:Twelve of the one hundred and seventeen (10%) dislocations had incongruent reduction, which was identified by the break in Shenton’s line and increase in medial joint space in seven patients, increase in the superior joint space in three patients, or increase in the joint space as a whole in two patients. CT scan identified the origin of the osteocartilaginous fragment as being from the acetabulum in six patients, the femoral head in four, and from both in one. One patient had an inverted posterior labrum. Following debridement, congruent reduction was achieved in all patients. At an average follow-up of 5 years (range: 2 years 5 months to 8 years), the outcome as evaluated by Thompson and Epstein clinical criteria was excellent in eleven cases and good in one case; the radiological outcome was excellent in eight cases and good in four cases.Conclusions:Intra-articular loose bodies were identified by nonconcentric reduction in 12 out of 117 patients with simple hip dislocation. Careful evaluation by fluoroscopy and good quality radiographs are indicated following reduction of hip dislocations.
