Comparative Study[Dynamic pedobarography in postoperative evaluation of pes cavovarus].
Pes cavovarus is a complex deformity of the forefoot, the midfoot and the hindfoot, frequently of neuropathologic etiology. The goals of surgical interventions consist of anatomical and functional correction of the foot deformity by soft tissue and bony procedures. Preoperative planning and postoperative assessment are based on clinical and radiographic examination. The present study was undertaken to find out if pedobarographic outcomes correlate with those postoperative results and if the dynamic pedobarography provides useful information in the functional evaluation of cavovarus feet. ⋯ Pre- and postoperative assessment of the cavovarus foot is mainly based on static methods such as clinical and radiographic evaluation. The results of this study demonstrate that the dynamic measurement of plantar peak pressures and contact area offers limited information about functional and anatomical improvement after surgery. Patients with severe deformities and muscular discoordination have difficulties walking consistently on the platform at each trial and severe decrease of plantar contact area makes the exact positioning of the masks difficult, which leads to problems with standardised measurements. In this context, the dynamic pedobarography cannot be used as a profitable diagnostic tool which provides an objective measurement that can add a dynamic component to a clinical or radiographic examination.

[Degenerative lumbar spondylolisthesis treated with isolated intersomatic arthrodesis: results of 30 cases with an average 4-year follow up].
Degenerative spondylolisthesis of the osteoarthritic spine can lead to severe invalidating back pain, decompensating a clinical situation previously well controlled with drugs. Hypothesizing that such invalidating spinal pain might be related to the unstable olisthy, we treated our patients with isolated intersomatic arthrodesis without reducing the displacement. We present here our results in a retrospective analysis of 39 patients who underwent surgery between 1981 and 1992. ⋯ Strut plates screwed onto the vertebral bodies enabled intersomatic fusion in all cases. Stabilization of the olisthy alone, without correction of the displacement nor release of the canal, successfully relieved pain in all cases of severe radiculalgia due to osteoarthritic spondylolisthesis and even provided improvement of lumbar pain in patients with various levels of discopathy. Unstable olisthy would thus be the major cause of invalidating pain, particularly radiculalgia in these patients.

[Subfascial lipomatous tumors: management in a series of 37 consecutive cases].
The prognosis of subfascial lipomatous soft tissue tumors depends greatly on their histological type ranging from benign lipomas that cause little local or general problems to the severe prognosis of liposarcomas that exhibit both local and distant extension. However, the clinical presentation of the two types of tumors may be similar and thus quite misleading, sometimes leading to inappropriate management and severe consequences. The main objective of this study was to determine whether the preoperative work-up in patients treated for musculoskeletal tumors within our recruitment zone is adequate, allowing appropriate therapeutic decisions. In addition, we wanted to know what explorations are most pertinent for the differential diagnosis between benign and malignant subfascial lipomatous soft tissue tumors. ⋯ The clinical course of the benign lipomas and the sarcomas in this series confirm the radically different prognosis of these two tumors, both in terms of local extension and survival. Inadequate management in the initial diagnostic stages-i.e. lack of MRI with contrast injection, biopsy and multidisciplinary interpretation prior to treatment-raises the risk of higher morbidity, particularly a significantly greater number of reoperations, and progression to a higher grade of malignancy for two tumors. Our retrospective analysis enabled us to develop a decision making tree for patients with subfascial lipomatous tumors. Prospective validation will be necessary.

Case Reports[Bipolar dislocation of the forearm: elbow and perilunate dislocation].
We report a case of bifocal dislocation of the forearm due to posterior dislocation of the elbow and transcaphocapital retrolunate dislocation of the carpus, Fenton's syndrome, associated with fracture of both bones of the forearm. The emergency procedure achieved reduction of the elbow, plate fixation of the radius and ulna, used a posterior and an anterior access to achieve reduction and osteosynthesis of the radial styloid, the scaphoid, and the capitatum and temporary schapholunate, triquetrolunate, scaphocapitate, and radiolunate pinning. At ten months, the patient only complained of moderate pain for exceptional efforts. ⋯ Wrist flexion and extension were 50 degrees and 30 degrees respectively. X-rays demonstrated union of the scaphoid and the capitatum. There was no scapholunate diastasis and the scapholunate angle was normal.
