Interprosthetic femoral fractures-A challenge of treatment. A systematic review of the literature.
The success of prosthetic surgery has led to an increase in the percentage of the population having more than one prosthetic implant. This, combined with an increase in the average life expectancy and functional requirements for the elderly, has led to a higher incidence of periprosthetic and interprosthetic fractures. More precisely, the femoral shaft is compressed between two ipsilateral implants with most of these fractures being located on the supracondylar femoral shaft. ⋯ Treatment must be determined and assessed according to the type of fracture, the stability of the prosthesis, the bone quality and the general condition of the patient. There is little information in the literature about this type of injury: there are several published case reports detailing unconventional solutions and the case studies presented are limited and not significant. This review aims to provide an updated and comprehensive list of diagnostic and therapeutic protocols accepted today, while recognising that these protocols are being continuously updated according to experience gained.

Traumatic lesions at the elbow involving great loss of substance are uncommon, but represent a significant problem when such cases are referred to a trauma department. Most of these injuries may cause severe final functional impairment, thereby jeopardising future activities, particularly in cases where treatment was delayed or inappropriate. ⋯ Each type of tissue loss should be managed by choosing the most suitable technique from the armamentarium of reconstructive surgery, taking into account different priorities and the optimum timing (immediate or delayed, one- or two-stages). The authors describe a spectrum of indications and techniques that can be useful tools in managing these injuries.

Vascularised fibular grafts (VFGs) are widely used for primary reconstruction of long bones after bone tumour resections. The biological properties of VFGs are such that they can be a useful option even in failed intercalary reconstructions. The purpose of the current study was to investigate the results and the morbidity of VFGs as a salvage procedure in failed previous reconstructions after intercalary bone tumour resection of the femur. ⋯ Significant hypertrophy of the VFG was detected in seven of nine evaluable patients. At final follow-up the mean Musculoskeletal Tumour Society (MSTS)'93 functional score of the nine evaluable patients was 90% (range 66-100%). These results indicate that VFG is a valid salvage procedure in failed intercalary reconstructions of the femur after bone resection.

To determine the efficacy of core decompression (CD) technique combined with recombinant morphogenetic proteins, autologous mesenchymal stem cells (MSCs) and xenograft bone substitute into the necrotic lesion of the femoral head on clinical symptoms and on the progression of osteonecrosis of the femoral head. ⋯ This long-term follow-up study confirmed that CD technique combined with recombinant morphogenetic proteins, autologous MSCs and xenograft bone substitute may be an effective treatment for patients with early stage osteonecrosis of the femoral head.
