Management of high energy intra-articular fractures of the proximal tibia, associated with marked soft-tissue trauma, can be challenging, requiring the combination of accurate reduction and minimal invasive techniques. The purpose of this study was to evaluate whether minimal intervention and hybrid external fixation of such fractures using the Orthofix(More)
INTRODUCTION In patients who have undergone a total joint replacement, any mass occurring in or adjacent to the joint needs thorough investigation and a wear debris-induced cyst should be suspected. CASE PRESENTATION An 81-year-old man presented with a painful and enlarging mass at the popliteal fossa and calf of his right knee. He had had a total right(More)
BACKGROUND Detailed knowledge of cervical canal and transverse foramens' morphometry is critical for understanding the pathology of certain diseases and for proper preoperative planning. Lateral x-rays do not provide the necessary accuracy. A retrospective morphometric study of the cervical canal was performed at the authors' institution to measure mean(More)
Osteosarcoma is the most common primary bone cancer. Mutations of the RB gene represent the most frequent molecular defect in this malignancy. A major consequence of this alteration is that the activity of the key cell cycle regulator E2F1 is unleashed from the inhibitory effects of pRb. Studies in animal models and in human cancers have shown that(More)
Management of distal tibia fractures remains challenging. The purpose of this study was to evaluate whether hybrid external fixation, as definite treatment, was associated with satisfactory results and low rate of complications. Between November 1999 and October 2006, 48 patients (33 men and 15 women) with a mean age of 45.6 years and a median ISS of 14.3(More)
The neck–tongue syndrome (NTS) is a disorder, due to the compression of the second cervical root nerve. The compression occurs either at the atlanto-axial space or at the exit of the hypoglossal nerve. Many factors can be held responsible for the development of the lesion, including atlanto-axial dislocation, rheumatoid arthritis and irritation from the(More)
This report describes an 80-year-old woman who underwent intraarticular steroid treatment for her arthritic knee and ended up with avascular necrosis of her medial femoral condyle. This rare complication should alert all clinicians that even minor procedures such as arthrocentesis may result in complications.
We present the case of a 50-year-old male with consistent back pain, not resolving with conservative treatment. Plain radiograms demonstrated a lytic lesion at the level of the 8(th) thoracic vertebra. Thorough examination with computerized tomography and magnetic resonance imaging revealed a hemangioma extending to the posterior third of the vertebral(More)
We present the case of a nineteen year old male, who sustained a fracture of anterior-superior surface of C7, combined with anterior subluxation at the level of C6-C7 vertebrae. After x-ray and CT examination, he was treated conservatively by a Halo-vest. After mobilization, the patient was discharged from the hospital with instructions to visit the(More)
