Peroneal Nerve Palsy due to Bulky Osteochondroma from the Fibular Head: A Rare Case and Literature Review.

Common peroneal neuropathy is the most common compressive neuropathy in the lower extremities. The anatomical relationship of the fibular head with the peroneal nerve explains entrapment in this location. We report the case of a 14-year-old boy admitted with a left foot drop. The diagnosis was an osteochondroma of the proximal fibula compressing the common peroneal nerve. The patient underwent surgical decompression of the nerve and resection of the exostosis. Three months postoperatively, there was a complete recovery of the deficits. The association of osteochondroma and peroneal nerve palsy is rare. Early diagnosis is required in order to adjust the management and improve the results. It is worth to underscore that surgical resection is proven to be the appropriate treatment method ensuring high success rates.

[Intraosseous ganglion cyst of the capitate: a case report]. / Kyste synovial intraosseux du capitatum : à propos d'un cas.

Intraosseous cyst of the carpal bones is a rare cause of wrist pain. Few cases have been reported. We report a rare case of intraosseous ganglion cyst of the capitate, in a girl aged 16 who plain of chronic pain of the right wrist. The radiological assessment showed an osteolytic lesion with marginal sclerosis. The diagnosis was confirmed by histopathology and treatment consisted of curettage with autologous cancellous bone graft. At 8 months follow-up, the capitate is fully consolidated and the functional result is satisfactory.

[Bilateral floating forearm: a case report]. / Avant-bras flottant bilatéral : à propos d'un cas.

The combination of elbow dislocation and perilunate dislocation is rare. The prognosis of this condition depends mainly on that of the wrist. While some cases of floating forearm have been reported, no bilateral affection has -of yet- to our knowledge, been published. The authors report a case of a young patient who presented with bilateral floating forearm after a fall from a height. The treatment was surgical at the wrist. The functional result is similar to cases reported in the literature.

[Chondroma of the acromion: an unusual localization]. / Le chondrome de l'acromion : à propos d'une exceptionnelle localisation.

The scapula is an uncommon site for a chondroma. We report the case of a chondroma in the left acromion, which presented as a painful shoulder in a 19-year-old teenager. The diagnosis was suspected on radiographs and CT scan and confirmed by histological findings.

[Patellar pathologic fracture secondary to aneurysmal bone cyst. A case report]. / Fracture pathologique de la patella sur kyste anévrismal osseux. A propos d'un cas.

Aneurysmal bone cyst is a tumor-like lesion which accounts for about 1% of all biopsied tumors and tumor-like lesions of bone. We report an extremely rare case of aneurysmal bone cyst of the patella in an 18-year-old patient revealed by a pathological fracture. The unexpected appearance of a pathological fracture affects the whole therapeutical management. However, in the case of a well-preserved articular surface, curettage and corticocancellous grafting are considered to be successful methods of treatment for aneurysmal bone cyst of the patella, as revealed in our study.

[Pisiform-hamate synostosis with ulnar neuropathy. Case report]. / Compression du nerf cubital dans le canal de Guyon secondaire à une synostose pisiforme-os crochu. A propos d'un cas.

Entrapment of the ulnar nerve at the wrist is rare compared with the more commun site at the elbow. This condition was secondary to reccurent blunt trauma, ganglion cyst, vasculitic disorders, and fibrous bands. Compression of the ulnar nerve caused by pisiform-hamate coalition is rare entity. One case of this condition is reported.

[Osteoblastoma in the proximal radio ulnar joint]. / Ostéoblastome de la petite cavité sigmoïde du cubitus.

Osteoblastoma is a benign but painful bone tumour, which can only be treated surgically. Localization at the elbow is rare and poses diagnostic problems. The tumour in this location causes joint stiffnesses due to pain and the regional inflammatory response. A delay in diagnosis can, despite successful treatment of the tumour, cause loss of the full range of movements of the elbow. We report a case illustrating this aspect.
