A rare cause of chronic sciatic pain: Schwannoma of the sciatic nerve

Schwannomas are common, benign tumors of the shelth of peripheral nerves. Sciatic schwannomas are rare. Their symptomatology usually mimics sciatic pain due to a herniated disc, which can delay the diagnosis. If there is no lumbar pain and lumbar MRI is normal, the sciatic nerve must be clinically and radiologically examined all along its course. We report a case of sciatic nerve schwannoma presenting with chronic sciatica which was diagnosed and monitored radiologically for several years before successful surgical resection.

Schwannoma of the Median Nerve: Diagnosis Sometimes Delayed

Schwannoma is a tumor that develops from nerve sheath. The authors report an unusual case of schwannoma of the median nerve (MN) that remained asymptomatic for four years. The diagnosis was based on MRI (magnetic resonance imaging) and histopathological examination. Surgical removal is usually curative. The asymptomatic character of the tumor and its slow evolution remain an essential factor in diagnosis delays. This tumor has a good prognosis with a low recurrence rate and potential for malignant transformation.

The Monteggia fracture: series of 20 cases

The Monteggia fracture is one of the pitfalls of conventional diagnosis of upper limb trauma. Through a retrospective study of 20 cases diagnosed at the Department of Orthopaedic Surgery and Traumatology, University Hospital Center, Ibn Sina, Mohamed V University, Rabat, Morocco, between 2010 and 2014, we have tried to do an update on the management of Monteggia fractures either at of paraclinical exams or the surgical management. We support the idea that the dislocation of the radial head should be sought systematically to any isolated fracture of the ulna, for not to miss fracture Monteggia authentic. Rehabilitation of the upper limb must be done as soon as possible.

Cubitus varus: l'ostéotomie de soustraction externe a-t-elle toujours sa place? Etude rétrospective à propos de 25 cas

Cubitus varus or malunion is most often secondary to displaced supracondylar fractures of the lower end of the humerus in children. Various surgical techniques have been proposed with different success rates but also with different reported complication rates. Our retrospective study of 25 cases diagnosed at the University Hospital of Rabat evaluated the results of the technique of external subtraction which was used in our training to handle this deformation.

Osteoblastoma of the carpal navicular: a case report and review of the literature

Osteoblastoma of the scaphoid is an infrequent cause of hand and wrist pain. The few reported cases emphasize the rarity of osteoblastoma in hand and wrist localizations. Pathological examination is mandatory before treatment due to lack of distinctive clinical and radiological features. We report the case of a 17-year-old right-handed girl who presented with a more than 7-month history of progressive right-wrist pain. No history of trauma was reported. Conservative treatment with anti-inflammatory medications before referral was unsuccessful. The authors present the diagnostic difficulties and the treatment that was applied: proximal row carpectomy. Treatment options, according to the literature, also include scaphoidectomy and tumor curettage with bone grafting.
