Comparative Study[Intramedullary pinning of diaphyseal fractures of both forearm bones in adults: 46 cases].
The goal when treating shaft fractures of the forearm bones is to obtain good bone healing with good preservation of upper limb function. We report a retrospective (1995-2004) consecutive series of patients aged 32 years on average (range 16 to 92 years) who presented 46 shaft fractures of both forearm bones. ⋯ Intramedullary pinning is an attractive alternative for the treatment of shaft fractures involving both forearm bones in adults. Best results are obtained if the fracture (situated outside the 5th sixth) can be stabilized without opening the focus with a single 2.5 mm pin. This method combines the advantages of closed osteosynthesis, that is, a simple nontraumatic procedure decreasing the risk of suppuration, and early return of function, limiting postoperative immobilization. It enables early sturdy bone healing with a low risk of recurrent fracture.

Comparative Study[Volar fixed angle plate LCP 3.5 for dorsally distal radius fracture. About 24 cases].
Fracture of the distal radius with posterior displacement is the most common wrist fracture. Pinning is generally proposed. The problem is that a secondary displacement may persist, even for the least complex fractures. With the advent of the fixed-angle plate with a self-locking screw, we considered using this method in combination with an anterior approach to the radius. We report our preliminary results. ⋯ This study demonstrated that, used on the anterior aspect of the radius, the locking compression plate provides satisfactory treatment for fractures of the distal radius with posterior displacement. Because of the angular stability, the reduction can be maintained over time so that secondary displacement is no longer a problem. This is a difficult technique which requires particular skill. We no longer recommend the LCP 3.5 plate due to the poorly adapted ergonometry, the late fracture over the plate and the fact that the material is not removed.

Traumatic hip dislocation is a rare event in children. Appropriate management remains a subject of debate. The purpose of this study was to investigate the epidemiological, therapeutic features of this situation and the long-term outcome after treatment. ⋯ Traumatic dislocation of the hip joint is rare in very young children, but results from a minimally traumatic event. This suggests the presence of predisposing factors in this category of patients, particularly capsuloligamentary hyperlaxity. After reduction, immobilization can be recommended. Traumatic hip dislocations in children are different from the adult variety due to their rarity, the general absence of associated fractures, easy reduction and better prognosis. The epidemiological and therapeutic features in children older than six years are however similar to those in adults.

[Treatment of femoral fracture on previous implants with minimally-invasive surgery and total weight-bearing: benefit of locking plate. Preliminary report].
We report a consecutive prospective series of femoral fractures on previous implants. The purpose was to assess treatment with locking compression plates and total weight-bearing. ⋯ Locking plates have been shown to be an effective treatment for femoral fractures on previous implants allowing a stable fixation sufficient for early weight bearing.

[Correction of stiff thoracic idiopathic adult scoliosis. Prediction from the traction radiograph].
The aim of this study was to determine the predictive value of the traction radiograph in adults with stiff curve (preoperative Cobb angle>60 degrees and reduction of less than 35% with traction) thoracic scoliosis. We wanted to compare this predictive value with that observed in reducible scoliosis. ⋯ The standard traction radiographs were highly predictive of postoperative reduction of stiff thoracic and thoracolumbar curves treated by segmental instrumentation. The postoperative result can thus be estimated with a margin of error of +/-7 degrees . For the stiff curves, the postoperative Cobb angle was 17.5 degrees on average less than predicted on the traction radiograph (on average 20% supplementary gain in reduction). This angle gain, which was greater for stiff than reducible curves, corresponds to the determining effect of release occurring with stiff curves. Finally, because of the stronger correlation between the traction Cobb angle and the postoperative Cobb angle for stiff curves, the predictive value of the traction radiograph is greater for stiff curves than for reducible curves. In conclusion, one of the contributions of the traction radiograph, which results from the predictability of the postoperative angle with a small margin of error, is to enable adequate prediction of the postoperative outcome for a given patient or a specific sub-group of patients, e.g. with or without anterior release.
