Stiffness is common following fractures around knee. Manipulation under anesthesia (MUA) is the initial noninvasive procedure usually performed for such patients. Though MUA has been extensively evaluated for knee arthroplasty, there is paucity of literature regarding its benefits in trauma cases. The purpose of this study was to define the role of manipulation in post traumatic stiff knees. ⋯ MUA is a suitable non invasive treatment option for post traumatic stiffness. There is no effect of timing on outcome and late manipulation also results in good outcome. Extensor mechanism rupture and pre manipulation ROM<30° or flexion <40° are associated with failure and such cases should be considered for alternative options for better outcome.

Recalcitrant humeral non-union is a disabling condition that is extremely difficult to treat. The use of BMP-7 has been proposed to improve bone healing. This is a report of the results obtained in 12 patients with recalcitrant humeral non-union treated using stable fixation with a long locking compression plate and BMP-7, autologous bone graft and hydroxyapatite pellets applied at the non-union site. ⋯ At follow-up, non-union had healed in all patients by an average of 7.3 months. All the patients were very satisfied with their final results, despite a restricted range of motion of the elbow and a moderate muscular atrophy, which was frequently observed. Our study shows that BMP-7 associated with autologous bone grafting and hydroxyapatite pellets after stable fixation is an effective adjuvant to stimulate bone healing in the treatment of recalcitrant humeral non-union.

We hypothesize that inserting a curved intramedullary internal fixation device which follows curved osseous fixation paths (OFPs) would be more versatile and mechanically stronger than straight screws for fixation of pelvic ring and acetabular injuries. This study characterizes the dimensions of curved OFPs of the pelvic ring and acetabulum and suggests design parameters for such a curved device. ⋯ This study shows that if a flexible implant which could be stiffened once in place was available, it would enable the use of larger and longer fixation taking advantage of the pelvis's curved intracortical spaces. Even for dysmorphic pelves, accessible tunnels support a long, strong, curved fixation device.

The goal of the study was to evaluate both clinical and radiological outcome of a consecutive series of 11 patients submitted to lumboiliac fixation after lumbopelvic disjunction or associated injuries of the pelvis and lumbosacral tract in mid- and long-term follow-up. ⋯ Lumbopelvic fixation is an effective surgical technique for treatment of spinopelvic disjunction. The patient numbers in this series, and in the literature in general, are low; therefore, a multicentre study is advisable to give evidence and statistical importance to our findings.

Infection in megaprostheses remains an unsolved problem, with a rate of occurrence ranging from 5% to 12%. Silver coating of medical devices has recently been proposed to reduce infection rate because of the antibacterial effect of silver. This innovation could be particularly interesting for megaprostheses, but few data have been reported in the literature. ⋯ Silver-coated megaprostheses showed promising results in this series in terms of prevention of infection in a high-risk group of patients, many of whom had a history of infection. No side-effects were detected. The circulating silver levels confirm both the persistence of silver-coating activity after three years and the safety of silver-coated implants. Longer follow-up and larger series are needed.
