Patellar tendinopathy is characterized by activity-related anterior knee pain. It is most commonly related to sports activity, but has also been reported in the non-athletic population. Most injuries are caused by microtrauma, resulting in tendinitis or tendinosis. Extraskeletal paraarticular osteochondromas, which occur in the soft tissues near the joint, are rare. The infrapatellar fat pad an...

Osteochondroma is a cartilage capped benign tumor developing mainly at the juxta-epiphyseal region of long bones. The rate of malignant transformation, mainly into chondrosarcoma, is estimated to be less than 1-3%. Transformation into osteosarcoma is very rare and has been reported only thirteen times. There is little information on treatment and outcome. We report the case of a secondary ...

We retrospectively evaluated the results after ulnar lengthening and radial deformity correction using an external fixator for forearm deformities caused by osteochondromas. Eight forearms were treated surgically in seven patients with multiple hereditary osteochondroma. The mean follow-up time was 40 months (range, 20 to 60 months). The average radial articular angle improved from 43 degrees t...

A 19-year-old man presented with a 5-year history of back pain radiating to the lower extremities and paresthesis of the toes during the last year. Plain X-ray revealed a large cauliflower shaped exophytic mass at the level of T8, T9 and T10 vertebrae. Computed tomography (CT) and magnetic resonance imaging (MRI) showed an abnormal bony mass arising from the posterior arch of T9 with protrusion...

Painful snapping of the scapula may have an anatomical cause but is usually idiopathic. Most patients respond well to conservative measures such as physiotherapy or non-steroidal anti-inflammatory drugs. Surgery can be performed if conservative treatment is unsuccessful. Conservative measures are less likely to be successful if a clear anatomical cause can be found. Several surgical techniques ...

Background. Conventional osteochondromas are common bone lesions developing in the metaphyseal region of growing skeleton. Marginal excision is the treatment of choice for such tumours. Extraosseous cartilaginous tumours are rare and their biological potential is poorly characterized. Case Presentation. A-52-year old woman presented with 3-year history of fullness and dull pain and inability to...

Osteochondromas are the most common benign tumor of the bone. They are sometimes responsible for vascular complications involving either veins or arteries, principally around the knee. Pseudoaneurysms are considered a rare condition. The authors describe the occurrence of a pseudoaneurysm of the popliteal artery in association with a femoral osteochondroma in a 30-years-old man.
