PURPOSE To reevaluate at medium term the results of computed tomography (CT)-guided percutaneous resection of osteoid osteomas. MATERIALS AND METHODS Thirty-eight patients who had undergone treatment by means of this technique were reexamined with a mean follow-up of 3.7 years. The short- and medium-term clinical course and histologic features of the(More)
Nineteen shoulder arthroplasties for the treatment of nontraumatic avascular necrosis of the humeral head were evaluated. The osteonecrosis was idiopathic in 6 shoulders, was a result of corticotherapy in 10, occurred after radiation in 2, and occurred after Gaucher's disease in 1. A total shoulder arthroplasty was performed in 5 cases and a(More)
INTRODUCTION Surgical site infections (SSI) studies rely on an imprecise and debatable definition. The term "wound healing problems" (WHP), not necessarily septic, is also frequently cited. This study had the objectives of determining the frequency of early SSIs in traumatology, these terms eventual correlation, and the factors influencing onset. PATIENTS(More)
INTRODUCTION The aim of our study was to evaluate the results of surgical treatment of clavicle non-union after failure of conservative treatment. Our hypothesis was that stable fixation with bone graft derived from local bone stock (fracture site) or the iliac crest was essential to achieve bone union. MATERIAL AND METHODS Twenty-one patients with a(More)
To date, chemosensitivity to neoadjuvant chemotherapy of patients with high-grade osteosarcoma is evaluated on surgical resection by evaluation of the percentage of necrotic cells. As yet, no predictive profile of response to chemotherapy has been used in clinical practice. Because we have previously shown that the integrin pathway controls(More)
In 24 patients with presumed osteoid osteoma in the appendicular skeleton (n = 23) and lumbar spine (n = 1), percutaneous resection with a drill system and computed tomographic (CT) guidance was performed. In the procedure, a 7-mm-diameter toothed drill inserted over a guide wire is used to remove the nidus. Twenty-three patients were successfully treated.(More)
INTRODUCTION Despite many papers and instructional course lectures, therapeutic guidelines are not clearly defined about treatment of femoral neck fractures. The aim of this multicentric French symposium was to prospectively study the results of current therapeutic options in order to propose scientifically proven options. MATERIAL AND METHODS Three(More)
INTRODUCTION The occurrence rate of common peroneal nerve (CPN) palsy associated with knee dislocation or bicruciate ligament injury ranges from 10 to 40%. The present study sought first to describe the anatomic lesions encountered and their associated prognoses and second to recommend adequate treatment strategy based on a prospective multicenter(More)
Therapeutic resistance of acute myeloid leukemia stem cells, enriched in the CD34(+)38(-)123(+) progenitor population, is supported by extrinsic factors such as the bone marrow niche. Here, we report that when adherent onto fibronectin or osteoblast components, CD34(+)38(-)123(+) progenitors survive through an integrin-dependent activation of glycogen(More)
