Marjolin's ulcer of the forearm from 30-year-neglection of external fixator.

Background: Marjolin's ulcers are a rare form of malignancy that present at regions exposed to chronic infection. They present with a clinical triad of nodularity, induration, and ulceration greater than 3 months.

Case Report: We present herein, an extremely rare case of Marjolin's ulcer of the forearm, secondary to osteomyelitis, resulting from a 30-year neglection of external fixator used to treat a war injury of the forearm.

Evaluation of spinal cord compression and hyperintense intramedullary lesions on T2-weighted sequences in patients with cervical spondylotic myelopathy using flexion-extension MRI protocol.

Background Context: Acquired cervical stenosis is caused by the combination of disc protrusion, facet joint degeneration, hypertrophy of the ligamentum flavum, and osteophyte formation. Although these mechanical factors seem to play an important role in the pathogenesis of myelopathy, the role of dynamic factors has been suggested by many authors. Based on these results, dynamic magnetic resonance imaging (MRI) was proposed to improve diagnostic techniques in patients with cervical myelopathy.

Reliability of a new method for evaluating femoral stem positioning after total hip arthroplasty based on stereoradiographic 3D reconstruction.

The goal of this study was to validate a new method for determining femoral stem positioning based on 3D models derived from the EOS biplanar system. Independents observers measured stem anteversion and femoral offset using CT scan and EOS system of 28 femoral stems implanted in composite femurs. In parallel, the same parameters were measured on biplanar lower limb radiographs acquired from 30 patients who had undergone total hip arthroplasty.

Arthroscopic transfer of the pectoralis major for irreparable tear of the subscapularis: a preliminary report.

An irreparable tear of the subscapularis is a surgical challenge. Open approaches have been widely described to restore the anatomy and the function of the shoulder. Pectoralis major transfer is the most common technique used in this difficult clinical situation.

Osteochondritis of the distal tibial epiphysis.

Osteochondritis of the distal tibial epiphysis is a very rare entity. 9 cases have been described in 7 articles and 8 other cases have been mentioned in textbooks. This paper describes the 10th case of osteochondritis of the distal tibial epiphysis and summarizes the clinical and radiological presentations of the 9 other cases.
