Fracture du corps du talus associée à une fracture malléolaire médiale: à propos d’un cas bilatéral

The authors report a case of bilateral and simultaneous medial malleolar and talar body fractures. A case of 39-year-old man sustained a trauma of both ankle from road traffic accident. The mechanism, management, and outcome of this lesion are discussed.     

Luxation postéro-médiale du coude associée à une fracture du condyle latéral et du processus coronoïde chez un adolescent : à propos d’un cas

We report the occurrence of a rare injury in a teenager not yet described in the literature: the association of posteromedial elbow dislocation, lateral condyle and coronoid process fractures. The treatment required fixation of lateral condyle and coronoid process thanks to lateral and medial approaches and capsular fixation. This lesion is unstable, such as the terrible triad described in adults. It requires external and anterior stabilization of the elbow. The management of such injuries of the elbow is complex. It must consider both bone and ligament instability, and risk of injury to growth plates.     

Synostose scaphotrapézienne associée à un syndrome du canal carpien chez une enfant de neuf ans : à propos d’un cas

This report describes a case of congenital synostosis between two bones of the wrist scaphoïd and trapezium in a nine-year-old girl who presented a severe tunnel carpal syndrome treated two years ago by open surgery. This association has not previously described.     

Fracture du scaphoïde carpien associée à une fracture de l’extrémité inférieure du radius chez l’enfant. À propos de deux cas

The authors report two cases of concomitant scaphoid and distal radial fractures, a rare combination of lesions in children. The first case was in a 14-year-old boy who presented a midscaphoid fracture associated with a distal forearm fracture. The second case concerned a 13-year-old boy who presented a midscaphoid fracture associated with a Salter type II distal radial fracture. Both fractures were reduced under general anaesthesia. The total period of immobilisation was 3 months, using a large arm thumb cast. Associated scaphoid fractures should be suspected with all types of distal forearm injuries in children. Reduction of the radius fracture should be done carefully to avoid possible displacement of the scaphoid fracture.     

Métastases osseuses d’un épendymome d’emblée de double localisation. À propos d’un cas

A case of cerebral and sacral ependymoma revealed by cerebellar syndrome and sciatica in a 68-year-old man is reported. Bone metastases were diagnosed seven months after surgical excision of the brain tumor.     

Ténosynovite isolée à gonocoque, à propos d’un cas et revue de la littérature

Isolated gonococcal tenosynovitis is rare, and is part of disseminated gonococcal infection. It is due to blood-borne contamination of the flexor tendon sheath. One to 3% of gonococcal mucosal infections develop disseminated infections. Tenosynovitis is present in two-thirds of cases, sometimes in association with arthritis and skin rash. We report a case of a 26-year-old man with isolated gonococcal tenosynovitis of the thumb, with no other medical history, occurring 15 days after unprotected sex. Except local inflammatory signs of the thumb extending to the wrist, and a biological inflammatory syndrome, the patient had no arthritis, skin or mucosa symptoms. Immediate surgical drainage was performed under antibiotic cover with 3rd generation cephalosporin. All bacteriological samples were negative, except for one blood culture positive for Neisseria gonorrhoeae. Thus, in case of an asymptomatic patient with suspected gonococcal infection through a mucus portal, a precise examination, including geographical and sexual history, and a review of screening are recommended. Although the pathophysiology of gonococcal tenosynovitis is still obscure, the best prevention remains that of sexually transmitted diseases.     

Rupture du tendon du fléchisseur radial du carpe après ostéosynthèse percutanée d’une fracture de scaphoïde. À propos d’un cas

We present a rare complication of percutaneous osteosynthesis of a scaphoid fracture. A 19-year-old professional handballer presented with a fracture of the scaphoid classified B2 according to the Herbert classification: the fracture was fixed with a percutaneous screw. The fracture was united by six weeks despite resumption of training eight days postoperatively. Subsequently, the patient presented with pain over the flexor carpi radialis (FCR) tendon together with reduction of wrist flexion strength suggested an FCR tendonitis. A CT scan with injection eliminated the diagnosis of non-union and showed protrusion of the distal end of the screw. After the failure of conservative treatment (corticosteroid injection), removal of the screw and synovectomy of the FCR were scheduled. During the procedure, attrition of the FCR tendon with scar tissue and metal inclusions in its fibres were observed. A visual examination of the screw's distal end showed a distortion of its hexagonal outline due to hammering, leading to metal projection likely to have caused the FCR tendon's attrition. We recommend the systematic burying of these canulated screws as well as changing any screw damaged during its insertion.     

Tumeur ténosynoviale à cellules géantes diffuse du poignet révélée par un syndrome du canal carpien : à propos d’un cas

Giant cell tumour of tendon sheath is a benign proliferative lesion of synovial origin that may affect the joints, bursae and tendon sheaths. It is the second most common soft tissue tumor of the hand after ganglion cyst. The localised (nodular) form is the most common. However, the less-common diffuse-type giant cell tumour is usually located in the peri-articular soft tissue. The authors report the case of a giant cell tumor of the tendon sheath arising from the carpal tunnel of the wrist in a 42-year-old woman. The patient presented a mild carpal tunnel syndrome and a mid-palmar swelling. We present an unusual localization of giant cell tumor of the tendon sheath, causing carpal tunnel syndrome.
