The purpose of this review was to assess the ten to 15-year outcomes of metal-on-metal hip resurfacing (MoM HR) when performed at designing and independent centres, and make recommendations for the future use of MoM HR. ⋯ There remains a role for MoM HR in young active male patients with primary osteoarthritis, provided the surgeon has sufficient experience in the procedure, the implant has an established record, and the patient is aware of the potential risks associated with MoM bearings and HR. Very experienced HR surgeons may also consider this procedure in females provided they meet the refined inclusion criteria described (including femoral head sizes of 46 mm and above).

Periprosthetic fractures of the acetabulum represent a rare incident in primary and revision total hip arthroplasty. The management of these fractures can be challenging. At present, there are no reliable guidelines for the treatment of periprosthetic acetabular fractures. ⋯ Assessment of the stability plays a crucial role before determining the treatment strategy. There is a large variety of surgical techniques available for the management of these fractures. This review article outlines the epidemiology, aetiology and current classification systems, and provides a distinct diagnostic and therapeutic algorithm for the treatment of periprosthetic acetabular fractures.

The best treatment for intra-articular fractures of the calcaneus is still debated. The aims of this study were to determine whether intrafocal reduction of thalamic fractures is effective, to evaluate whether a locking nail is able to maintain reduction of the articular surface and to analyse the functional results of this original method. ⋯ The posterior intrafocal approach for both reduction and locked nailing of intra-articular calcaneal fractures has been proven as an effective and reliable procedure.

Médecins sans Frontières (MSF) is one of the main providers of orthopaedic surgery in natural disaster and conflict settings and strictly imposes a minimum set of context-specific standards before any surgery can be performed. Based on MSF's experience of performing orthopaedic surgery in a number of such settings, we describe: (a) whether it was possible to implement the minimum standards for one of the more rigorous orthopaedic procedures--internal fixation--and when possible, the time frame, (b) the volume and type of interventions performed and (c) the intra-operative mortality rates and postoperative infection rates. ⋯ In settings affected by natural disaster or conflict, a high volume and wide repertoire of orthopaedic surgical procedures can be performed with good outcomes when minimum standards are in place. More demanding procedures like internal fixation may not always be feasible.

As the number of total hip arthroplasties (THAs) is increasing, the expected number of periprosthetic femur fractures is also expected to increase. As such, a thorough grasp of the evaluation and management of patients with periprosthetic femur fractures is imperative, and discussed in this review. ⋯ Periprosthetic femoral fractures after primary total hip arthroplasty are a complex and clinically challenging issue. The treatment must be based on the fracture, the prosthesis, and the patient (Table 1). The Vancouver classification is not only helpful in classifying the fractures, but also in guiding the treatment. In general, well-fixed stems require open reduction and internal fixation, whereas loose stems require revision arthroplasty.
