Peroneal nerve palsy caused by a synovial cyst of the proximal tibiofibular joint: a report of two cases and review of the literature.

Synovial cyst of the proximal tibiofibular joint is a very rare condition, for which there is no consensus regarding treatment. Two macroscopic forms may be encountered: extraneural cysts and intraneural cysts. We present the cases of two patients who had synovial cysts of proximal tibiofibular joint that caused peroneal nerve palsy.

Triplane fracture of the proximal tibia: a case report and literature review.

Triplane fractures of the proximal tibia are less well known than the distal extremity. The diagnosis is based on a good analysis of X-rays and possibly CT images to better plan the management. The authors reports a triplane fracture of the proximal tibial in a 12 year old boy treated by closed reduction and internal fixation.

Monteggia fracture with unreducable anterior dislocation of the radial head and a lesion of the external collateral ligament of the elbow.

Monteggia described a fracture of the proximal third of the ulna with anterior dislocation of the radial head from both the proximal radioulnar and radiocapitellar joints. The key treatment principle in Monteggia fractures is stable anatomic alignment of the ulna. We present an uncommon case of a Monteggia fracture-dislocation with an unreducable anterior dislocation of the radial head and associated with a lesion of the lateral collateral ligament of the elbow.

Intra-articular knee arborescent lipoma: a case treated with arthroscopic synoviectomy.

Arborescent lipoma is an unusual intra-articular lesion that typically develops in the knee and has to be evoked before chronic effusion. It corresponds to hyperplasia of mature fatty tissue and hypertrophy of synovial villi, developing within a joint. The reference treatment is synovectomy by arthrotomy.

Uncommon Floating Knee in a Teenager: A Case Report of Ipsilateral Physeal Fractures in Distal Femur and Proximal Tibia.

Introduction: The concomitance of ipsilateral physeal fractures of the distal femur and the proximal tibia is an extremely scarce entity. It is conceptually similar to floating knee in pediatric population.

Case Report: One case with this injury is reported in a 16-year-old teenager.

Chondroblastic osteosarcoma of the distal tibia: a rare case report.

Chondroblastic osteosarcoma, representing about 25% of osteosarcoma, is a fatal primary malignancy of the skeleton if not diagnosed and treated appropriately. It most commonly occurs in the long bones of the extremities near the metaphyseal growth plates. In this report, we describe the occurrence of chondroblastic osteosarcoma involving the left distal tibia in a 14-year-old male.
