Case Reports[Double localization of an osteoid osteoma of the ankle: percutaneous treatment by CT-guided drilling].
A 26-year-old woman presented a rare double localization of an osteoid osteoma of the ankle. The first focus was situated in the tibial metaphysic, bordering the distal tibiofibular joint. The second focus was also superficial, located in the neck of the homolateral talus. ⋯ Compared with disphyseal localizations, it is often more difficult to recognize an osteoid osteoma located in the foot or ankle. Scintigraphy and CT are necessary and sufficient for diagnosis. Progress in imaging techniques has greatly facilitated the treatment of osteoid osteomas, allowing excellent outcome with limited morbidity.

Clinical Trial[Treatment of proximal humeral fractures by Telegraph nail: prospective study of 34 cases].
Many developments have been devoted to improving osteosynthesis of proximal humeral fractures, but indications remain controversial. Anterograde nailing using a locked self-stabilizing nail is an attractive conception which has provided promising results. The purpose of this study was to assess the early results observed in a series of patients treated with a first-intention Telegraph nail. ⋯ The Telegraph nail provides reliable fixation for the treatment of extra-articular and simple articular fractures of the proximal humerus. Dislocated fractures are classical indications for arthroplasty, with acceptable results for a only slightly invasive procedure. The risk of osteonecrosis does not necessarily deteriorate shoulder function and secondary revision for insertion of a prosthesis is still possible. The radio-clinical correlations show the importance of reduction quality to obtain a good final clinical result. Among the nine cases of poor outcome, six were related to a misaligned callus with persistent valgus deviation of the head (alpha F<30 degrees ) and in some cases, excessive posterior tilt. The solidity and stability achieved with the Telegraph nail enabled healing in all cases of fracture in this series with immediate postoperative reduction in most. The stability being related to the quality of bone stock, primary arthroplasty remains an important indication when it appears that a solid osteosynthesis cannot be achieved.

[Computer-assisted combined femoral and tibial osteotomy for severe genu varum: early results in 16 patients].
The aim of this work was to assess radiographic outcome after double femoral and tibial osteotomy for severe genu varum. Among 197 computer-assisted osteotomies performed in our department between August 2001 and February 2006, 16 (8.1%) were double level osteotomies. ⋯ Computer-assisted double-level osteotomy is a reliable, accurate and reproducible method for the treatment of severe genu varum. The two failures observed in this series were within a tolerable range (177 degrees and 179 degrees). The use of a navigation procedure simplifies a technique which in general requires skillful application to achieve the preoperative objective. The development of this technique is important in order to avoid an oblique joint space which can compromise the success of subsequent prosthesis implantation.

Comparative Study[Total hip arthroplasty in patients with chronic renal failure transplant or dialysis].
Total hip arthroplasty (THA) is generally proposed for renal transplant patients with invalidating hip disease. For patients on chronic dialysis, the few published series report a higher rate of complications. These patients are considered more vulnerable. We report the results of a retrospective mid-term analysis of 28 renal failure patients (37 hips) with THA comparing renal transplant recipients with chronic dialysis patients. ⋯ In renal transplant recipients, total hip arthroplasty is a reliable treatment for hip disease, providing good mid-term results and a morbidity close to that observed in the general population. Conversely, dialysis patients have a greater perioperative morbidity. Use of non-cemented implants is not associated with a higher rate of loosening than with cemented implants. It can be recalled that this type of surgery must be performed within the framework of careful pluridisciplinary patient management.

[Acetabular revision for aseptic loosening in total hip arthroplasty using cementless cup and impacted morselized allograft].
Impaction grafting can be used in cementless fixation with morsellized bone, bone graft, and hemispherical cup. The first goal of impaction grafting in revision of total hip arthroplasty is to transform segmental defects into cavitary defects and obtain a full compaction of the graft in order to restore the bone stock. The second goal is to achieve primary stability of the cup. The third goal is to restore the hip center of rotation with a cup anatomically located in the acetabulum. The aim of our study was to evaluate the results of a surgical technique with impacted morsellized bone graft and a cementless press-fit cup for the revision with defect type III according to the AAOS classification. ⋯ Restoration of bone stock is one of the main goals during hip reconstruction after aseptic loosening. Clinical experience in our series has shown the reliability of the impacted morsellized bone graft allowing relocation of the center of rotation and good cup stability. Biological fixation of the cup and graft integration seems good at mid-term follow-up. The cup that we used in our series combined the advantages of a press-fit cup and those of a reinforcement ring. The combination of this type of cup with morsellized bone graft seems to be a reliable solution for restoring bone stock, relocating the hip center, and stabilizing the cup in revision total hip arthroplasty with type III acetabular defect according to the AAOS classification.
