PURPOSE: Revision of failed modular metal-on-metal total hip replacement (MoM-THA) can be technically difficult. A dual mobility liner can help to salvage a well-fixed acetabular component. The present paper reports the clinical and radiographic outcome of revision of failed Birmingham modular MoM-THA using a dual mobility liner. METHODS: The present study reports on ten patients (3 female and 7 male) with 11 revision THAs. Patients underwent revision an average of 51 months (range 40-73 months) after index procedure...

We used three-dimensional (3D) MRI to assess the sphericity of the cartilaginous femoral head in developmental dysplasia of the hip. We assessed 21 children using 3D-MRI. The smallest sphere including the femoral head cartilage was drawn, the diameter was measured, and the center of the sphere was defined. We compared the diameters of the femoral heads between unaffected and diseased sides. The diameter of the affected side was smaller, with flattening at the posteromedial area and proximoposterior areas. 3D-MRI showed that the shape of the dislocated femoral head was aspherical with focal growth failure...

BACKGROUND: Dual mobility implants are subject to a specific implant-related complication, intraprosthetic dislocation (IPD), in which the polyethylene liner dissociates from the femoral head. For older generation designs, IPD was attributable to late polyethylene wear and subsequent failure of the head capture mechanism. However, early IPDs have been reportedly affecting contemporary designs. METHODS: A systematic review of the literature according to the preferred reporting items for systematic reviews and meta-analyses guidelines was performed...

The knowledge of the pathophysiology of patients with severe trauma and the hemodynamic and inflammatory consequences of initial surgical management has led many surgeons to change their approach to the treatment of patients with severe polytraumas associated with lesions of the pelvis or of limbs by integrating the principles of sequential treatment or Trauma Damage Control Orthopaedic (TDCO). We report the case of a patient involved in a public road accident, admitted to hospital in a state of shock with pelvic disjunction and hip dislocation complicated by vascular injury in the same limb...

PURPOSE: Treatment of slipped capital femoral epiphysis (SCFE), including the modified Dunn procedure, restores anatomy with significant risk for avascular necrosis (AVN), if performed in the setting of moderate to severe, stable SCFE. The Imhauser osteotomy has been shown to be an effective way to correct residual deformity without the risk of AVN. We sought to evaluate the effectiveness and safety of a combined Imhauser osteotomy and osteochondroplasty, performed via a surgical hip dislocation approach for the acute and delayed treatment of stable SCFE...

PURPOSE: Children with cerebral palsy (CP) are at increased risk for hip dislocation. This can be prevented in most cases using surveillance programmes that include radiographic examinations. Known risk factors for hip dislocation include young age, high Gross Motor Function Classification System (GMFCS) level and high migration percentage (MP). The head-shaft angle (HSA) has recently been described as an additional risk factor. The study aim was to determine inter- and intra-rater reliability of the HSA in a surveillance programme for children with CP...

INTRODUCTION: The SOFCOT symposium (2005) on periprosthetic fractures of the femur (PFFs) highlighted a high rate of dislocation (15.6% at 6 months) after change of prosthesis. So far, no study has ever proved the benefit of dual-mobility articulation during PFFs revisions. We conducted a comparative study on two prospective cohorts in order to (1) assess the influence of systematic acetabular revision in favor of a double mobility on dislocation rate (2) and in order to evaluate the rate of morbidity associated with this extra surgical procedure...

Caudal Regression Syndrome (CRS) is a rare disorder which consists of abnormalities in the lumbosacral spine, rectum, urinary system and lower limbs. These abnormalities also include orthopaedic deformities, such as hip dislocation, knee-flexion contracture with popliteal webbing and talipes equinovarus. Because of the rarity of this condition, few medical personnel are aware of it. Here, we present a case of CRS in a 15-year-old girl with pressure ulcers on the lateral malleolus and plantar surface of the foot, which had come into contact with the wheelchair footrest...

INTRODUCTION: Incorrect acetabular component positioning during total hip arthroplasty (THA) may lead to dislocation, impingement, wear and revision. Surgeons commonly use the transverse acetabular ligament (TAL) as a landmark for acetabular component orientation. The posterior acetabular wall (PAW) is a structure easily viewed on plain radiography and its position can help guide acetabular component position. In this study, we examine the efficacy of preoperative radiographs in predicting cup position relative to the PAW...

We present a case of isolated intra-acetabular osteochondroma in a 21 year-old male who presented with history of right hip pain for 5 years and difficulty in walking. Patient was managed with excision of intra-articular exostoses through surgical hip dislocation. Intra-articular hip osteochondromas can be a rare cause of hip pain in patients with unexplained etiology, and their diagnosis and management can be challenging.
