Percutaneous Tenolig(®) repair under intra-operative ultrasonography guidance in acute Achilles tendon rupture.

Background: Acute Achilles tendon rupture can be treated conservatively or surgically. Open surgery restores tendon continuity but carries a risk of skin complications. Tenolig(®) is a device designed for the percutaneous biological treatment of acute Achilles tendon rupture.

Primary total knee arthroplasty in the management of epiphyseal fracture around the knee.

Introduction: Over the past few years the use of arthroplasty was broadened to treating complex epiphyseal fractures at the shoulder and elbow joints. Similar trends to treat this type of fractures at the knee are less documented. Based on a multicenter retrospective series study, the aims of this work is to evaluate the short term clinical results of total knee prostheses in the management of comminuted epiphyseal fractures around the knee, to identify the technical issues and fine tune the indications.

Complex proximal humeral fractures: a prospective study of 22 cases treated using the "Bilboquet" device.

Introduction: Despite recent improvements in surgical devices, complex proximal humerus fractures internal fixation still encounters frequent mechanical failures.

Hypothesis: The aim of this study was to confirm that the Bilboquet device (a design mimicking the cup-and-ball game) helps solving mechanical difficulties associated with these fractures internal fixation and to present a simplified version of the original surgical procedure.

Patients And Method: This non-randomised prospective study included 22 fractures in 22 patients, mean age: 70 years.

Prevention of post-coccygectomy infection in a series of 136 coccygectomies.

Postoperative infection is a regular complication in coccygectomy. The authors propose the use of a topical skin adhesive on the postoperative wound as a contribution to the prevention of this complication. It was used on the first 56 patients in this study.

Osteosarcoma: current status of immunotherapy and future trends (Review).

Osteosarcoma is the most common primary bone tumor and represents a major therapeutic challenge in medical oncology. While the use of aggressive chemotherapy has drastically improved the prognosis of the patients with non-metastatic osteosarcomas, the very poor prognosis of patients with metastasis have led to the exploration of new, more effective and less toxic treatments, such as immunotherapy for curing osteosarcoma. Compared to the numerous reports describing successful immunotherapy for other solid tumors, the number of reports concerning immunotherapy for osteosarcoma is low.

Phenotypic and functional analysis of lymphocytes infiltrating osteolytic tumors: use as a possible therapeutic approach of osteosarcoma.

Background: Osteosarcoma is the most common type of primary bone tumor. The use of aggressive chemotherapy has drastically improved the prognosis of the patients with non-metastatic osteosarcomas, however the prognosis of the patients with metastasis is still very poor. Then, new and more effective treatments for curing osteosarcoma, such as immunotherapy are needed.

A new experimental rat model of osteosarcoma established by intrafemoral tumor cell inoculation, useful for biology and therapy investigations.

Satisfactory experimental models for preclinical cancer studies must follow several criteria: (1) reproducibility of the method used to induce the tumor and (2) clinical, pathological and kinetic similarity with the corresponding human tumors. We developed a model of osteosarcoma locally induced by the intrafemoral injection of osteosarcoma (OSR) cells in Sprague-Dawley rats. This method yields nearly 80% of bone tumors at the injection site.
