In 1971, Harris introduced a metal backed acetabular cup to allow replacement of worn polyethylene cups and it has been popularly used now. In metal backed acetabular cup, dissociation between metal shell and polyethylene liner usually occurs with hip dislocation. We report a case of dissociation of polyethylene liner in metal bacded cup not associated with hip dislocation.

Objective: We aim to study the prevalence and predictive factors for hip displacement, in order to justify a hip surveillance programme for children with cerebral palsy (CP) in Malaysia. Methods: Children aged 2 to18 years old with CP were recruited from September 2013 till June 2014. The hip joint migration percentage (MP) and acetabular index (AI) were measured on all hip radiographs. The CP subtype was determined and gross motor function was classified according to the gross motor function classification system (GMFCS). Results: Seventy-five children were recruited. Fifty-five percent of them had marked hip displacement with MP > 30% and 15% developed hip dislocation (MP=100%). Marked hip displacement occurred as early as age of 2 years and most hip dislocations were detected by age of 10 years. The risk of marked hip displacement was directly related to the GMFCS level, from none in GMFCS I to 75% in GMFCS V. There was a moderate positive correlation between the initial AI and initial MP. Conclusions: One in every two children with CP was at risk of hip displacement, with GMFCS level and initial AI as significant predictive factors. We recommend a hip surveillance programme for Malaysian children with CP, based on the child’s age and GMFCS level, with both MP and AI as indicators for hip surveillance.

Fracture of the femoral head is relatively uncommon and usually caused by high energy injury. The femoral head fracture combined with hip dislocation results in severe damage to the hip joint, and therefore has been associated with poor functional outcome. The principle of the treatment is composed of urgent reduction of the dislocated hip and early anatomical reduction, with the goal of restoring a congruent and stable hip. In an effort to reach that goal, several methods have been used for treatment of the fracture after closed reduction of the hip. The purpose of this article is to review the indication of surgery, surgical methods, surgical approach, and clinical outcomes.

A cross-sectional study of 204 hip radiographs of high risk CDH (Congenital Dislocation of the Hip) group newborn, using: (1) The Tonnis critenrion of acetabular index upper limit 35 degrees. (2) The position of femoral metaphyseal "beak" with Perkins and Hilgenreiner's lines, showed: 21 CDH/204 risk newborn or 10.24% with 7.35% Dislocatable Hip, 2.93% Complete Dislocation; Female = 9.5:1; Left side: Right side=3:2.

Obturator (Inferior) type dislocation of the hip joint is a rare and the fracture of greater trochanter during closed reduction for it has never been reported in literature. In this report, we present a case of a fracture of greater trochanter during difficult closed reduction which required operative fixation. Surgeons need to be aware of this complication and excessive force for reduction should be avoided when treating of this type dislocation.

The presence of anterior hip dislocation along with contralateral posterior hip dislocation in the absence of other major traumas is a distinctly rare injury pattern. We report such a case, along with a review of previous cases. A 40-year-old male patient after motorcycle skidding had posterior dislocation of the left hip and anterior dislocation of the right one without other associated injuries. The patient underwent successful closed reduction of both hips. The clinical course and follow-up assessment of the patient was uneventful.

Simple posterior hip dislocations requiring open reduction is very few and reported approximately 3% of all posterior hip dislocations and we have little comments of the various causes preventing or blocking a concentric reduction following traumatic posterior hip dislocation. In a review of eleven cases of posterior dislocation requiring open reduction, we divided two groups, one is a failed closed reduction group, the other is a nonconcentric reduction group. A concentric reduction was prevented from an inverted limbus or an osteocartilagenous loose body from acetabulum or femoral head.

Traumatic hip fracture-dislocations are associated with chondral and labral pathology as well as loose bodies that can be incarcerated in the hip joint. Incarceration, such as interposed labrum between acetabulum and femoral head that is not readily visualized preoperatively, is a rare but important cause of pain and can potentially be a source for early degeneration and progression to osteoarthritis. We present three cases, arthroscopic surgery of incarcerated acetabular osseo-labral fragment following reduction of traumatic hip fracture-dislocation.

Traumatic simultaneous bilateral hip dislocation is reported rarely, but the most of them are limited in young patients. The authors managed the elderly patients whose both hip was dislocated traumatically, simultaneously and who didn't have any other underlying disease and other associated fracture - femur, hip joint and pelvis, with a review of the relevant literature.
