Isolated lesser trochanter fracture in adults: an early indicator of tumor infiltration.

We report on a case of isolated lesser trochanter fracture, without associated trauma, secondary to pulmonary adenocarcinoma metastasis. Treatment consisted in resection-reconstruction by megaprosthesis. This form of isolated fracture is rare, and results from infiltration of the trochanteric area by a malignant tumoral process, which is usually metastatic.

Ganglion cyst of the carpal navicular. A case report and review of the literature.

Intraosseous ganglion (IOG) cyst of the scaphoid is an infrequent cause of hand and wrist pain. Intraosseous ganglia located in the scaphoid have rarely been described in the literature. We report the case of a 30-year-old right-handed woman who presented with a more than 24-month history of progressive right-wrist pain. No history of trauma was reported.Conservative treatment with anti-inflammatory medications before referral was unsuccessful. Examination revealed a small palpable mass in the carpal navicular region with no limitation of normal wrist motion. An IOG cyst of the scaphoid was found on standard radiograph and CT-scan of the wrist. Treatment consisted in curettage of the cyst followed by packing of the defect with autologous cancellous bone graft harvested in the distal end of the radial metaphysis. Satisfactory functional recovery was achieved. The clinical, radiographic and therapeutic aspects of this rare condition are discussed by the authors.

[Iliopsoas abscess: a rare complication of pyogenic sacroiliitis in a child]. / Abcès du muscle iliopsoas : complication rare de la sacro-iliite à pyogène chez l'enfant.

Pyogenic sacroiliitis is a rare entity in children. Diagnosis is often delayed because of its variable clinical presentation, low suspicion by the examining physician, and rare findings on radiographs. Delayed diagnosis, however, results in complications such as iliopsoas abscess. We report the case of a 12-year-old girl hospitalized with a 21-day history of fever, pain in the left iliac fossa, and flexion contracture of the hip. On examination, she had fever (38.9 degrees C), psoitis, localized tenderness at the left sacroiliac joint, and pain elicited by lateral compression of the pelvis. The abdominal examination was normal. The erythrocyte sedimentation rate was 130 mm in the first hour, C-reactive protein was 186 mg/l, and the white blood cell count was 18,400/mm(3), with 79% neutrophils. Urinalysis was normal. Blood cultures were negative. Radiographs of the pelvis showed irregular left sacroiliac borders. The CT scan provided the diagnosis of sacroiliitis complicated by an ilioapsoas abcsess. Treatment was based on antibiotic therapy associated with surgical drainage. Bacteriologic investigation revealed Staphylococcus aureus. The patient's temperature returned to normal on the second day. Antibiotics were continued for 3 months, leading to full recovery.

Acute hematogenous osteomyelitis of the scapula in children.

PURPOSE OF THE STUDY: Osteomyelitis of the scapula is uncommon, often with a misleading clinical presentation. We report four cases of osteomyelitis of the scapula to illustrate the particular clinical imaging findings and treatment related to this location. CASE REPORTS: Between 1996 and 2006, four children were treated for osteomyelitis of the scapula, three boys and one girl, with a mean age of 8 years (range, 5-11 years). The time from symptom onset to hospitalization was 2 days. Pain was noted for all patients and total functional incapacity of the upper extremity was noted for three patients. The diagnosis of osteomyelitis of the scapula was established on the basis of imaging (ultrasound and CT scan). All patients were given medical treatment and underwent surgery. A positive bacteriology was noted in all patients. The bacterium isolated from blood cultures (two cases) and local samples obtained at the surgical site (four cases) were Meti-S Staphylococcus aureus. RESULTS: The results were analyzed by studying the anatomic and functional outcome at a mean follow-up of 36 months (range, 16-60 months). The patients were pain-free and had full range of motion in their shoulders. There were no complications. DISCUSSION: Few reports are available in the literature on osteomyelitis of the scapula. We discuss the specific clinical and imaging features as well as the treatment for this location.

[Palmar dislocation of the metacarpophalangeal joint. A case report]. / Luxation palmaire de l'articulation métacarpophalangienne des doigts longs: à propos d'un cas.

Palmar dislocation of the metacarpophalangeal joint of the long finger is a rare injury. The authors report a case of palmar dislocation of the metacarpophalangeal joint of the ring finger. The presumed mechanism is a combination of active flexion and forceful hyperextension. The dislocation was treated successfully by closed reduction shortly after injury. Closed reduction should be attempted in all cases of this injury.

["Floating fifth metacarpal". A Case report]. / "Un cinquième métacarpien flottant". A propos d'un cas.

We present the case of a patient with a fracture-dislocation of the fifth metacarpal and a dislocation of the metacarpophalangeal joint (floating fifth metacarpal) combined with a fracture of the fourth metacarpal. The mechanism of injury and management of this uncommon injury is reported. The "floating fifth metacarpal" and the fourth metacarpal fracture were reduced by closed techniques with percutaneous fixation. Twelve months later, the patient had a full range of wrist and finger movement, he was pain-free and without any residual disability.

[An unusual localisation of osteochondroma. A single case report]. / Une localisation exceptionnelle d'un ostéochondrome. A propos d'un cas.

Solitary osteochondroma is a rare benign tumour of the hand arising from the cortical surface. The important differential diagnoses, which should be considered, are Nora's lesion, florid reactive periostitis and Turret exostosis. The authors report an unusual case of osteochondroma of the metacarpal bone with a deficit of extension. The diagnosis was made using imaging techniques and confirmed by histological examination. The treatment is surgical, namely complete excision.
