Treatment of atrophic femoral non-unions according to the diamond concept: Results of one- and two-step surgical procedure.
The treatment of non-unions in long bones poses a great challenge, particularly in cases of infection or large osseous defects. This article evaluates the use of the diamond concept in the treatment of femoral non-unions in a one-step or two-step procedure according to the Masquelet technique. ⋯ One-step therapy is a suitable method of treatment for aseptic femoral non-unions with small osseous defects, using BMP-7 and RIA in the case of primarily failed atrophic non-union treatment. The Masquelet technique is an efficient means of eradicating infections in non-unions. In combination with intramedullary nailing, this technique is the method of choice for the treatment of femoral shaft non-unions with large defects.

Early results of the LPS™ limb preservation system in the management of periprosthetic femoral fractures.
Achieving skeletal fixation in the presence of progressive bone loss is a surgical challenge, especially in cases of periprosthetic fracture (PPF). Unpredictable fracture patterns and preexisting bone loss frequently combine in this patient group. Megaprosthetic arthroplasty allows for immediate mobilisation and shorter periods of rehabilitation. We describe the clinical outcomes of a cohort of LPS™ megaprostheses performed for PPF by a single surgeon at our institution. ⋯ We report minimal postoperative changes in functional outcome scores. The results of revision arthroplasty with LPS™ proximal femur megaprosthesis were satisfactory in 15/16 patients at a mean follow-up of 19.2 months. We recommend the use of megaprostheses in patients with markedly deficient bone stock for whom other available reconstructive procedures are unavailable.
