“…This study saw a 40% incidence, with an impaction in the obturator type of dislocation. The region of impaction is in direct contradiction to what was seen by Tehranzadeh et al (3). Their study revealed posterolateral impactions, whereas the defects in our study were in the anterior and superolateral margin of the head.…”

“…of all hip dislocations (2). The incidence of osteochondral impaction fractures of the femoral head, as identified on computed tomography (CT), may be as high as 63% for posterior dislocations and ranges from 12% to 100% for anterior dislocations (3,4). Acetabular fractures have been reported, but a detailed description of the type of fractures seen on CT is not present in the literature.…”

Anterior dislocation of the hip is a rare phenomenon, seen in only 5-10% of all hip dislocations. These dislocations can be divided into two types: superior or subspinous and inferior or obturator dislocations. Osteochondral impaction fractures of the femoral head are a known complication of anterior dislocation, but little has been reported on the types of acetabular and pelvic fractures associated with this dislocation. Five anterior dislocations were studied with radiographs and computed tomographic (CT) imaging, and the CT findings are described. Fractures were seen in the femoral head, acetabular roof, and medial wall, as well as in the anterior inferior iliac spine. The most severe injuries occurred after a superior dis. location, but the obturator dislocations demonstrated impaction fractures of the femoral head as well as an intra-articular bone fragment. CT of the acetabuli is recommended after reduction of these dislocations to identify these complications.(el,Word! Anterior hip dislocaUon; Computed tomography; Acetabulum

“…With the introduction of 3-D imaging it is possible not only to accurately diagnose the lesion but also stage it, which has a direct bearing on the surgical procedure to be employed. Early detection of avascular rotational osteotomy or core decompression with or without vascularized grafting initiated in the initial period lead to preservation of joint function [11]. In the present study 5 cases of avascular necrosis of the femoral head underwent 3-D CT imaging which clearly delineated areas of sclerosis, compression and contour alteration of head of femur along with acetabular involvement (Fig 7).…”

“…Using arthroscopy in 29 patients as a standard of reference, Khanna et al [82] showed that acute traumatic injury to the hip resulted in loose bodies (59%), intraarticular step deformities (38%), osteochondral lesions (49%), and labral tears (93%). Traumatic hip dislocation was shown to be frequently (20/32, 63%) associated with osteochondral impaction fractures [83], which typically result in posttraumatic osteoarthritis.…”
