Osteoid osteoma of a scapula: a case report in a 34 years old woman
The patient was a 34-year old woman with chief compliant of right radiculer shoulder pain for 4 years which referred to Shohada Training Hospital of Tabriz University of Medical Sciences.\nThe pain was decreased, with daily activity and increased at night.\nAt physical examination there was tenderness around shoulder with joint movement restriction over 90°of abduction with painful external rotation.\nShoulder plain x-rays were normal. The bone scan revealed obvious increased uptake at superolateral angle of scapula (). The CT scan showed relatively ossified 1cm nidus with mild peripheral hyperdencity (). The lesion was at a few millimeters from subchondral bone of glenoid (). Nerve Conduction Velocity (NCV) revealed neurogenic pattern at L5-L6 level muscles.\nIn the supine position with right shoulder elevation we performed a J shape incision such as the one used for coracoclavicular screw fixation. () Anterior insertion of deltoid to clavicle was incised with 1cm remnant.\nAfter coracoid exposure, we performed drill hole with 2.7 drilbit on the tip of the coracoid. Coracoid was cut leaving its tendon insertions attached. On the base of coracoid next to the glenoid there was small dimpling. After corticotomy 1.51/5cm dense calcified tissue was removed and the hole completely curetted.\nCoracoid was reattached using screw and deltoid sutured to clavicle. () The original pain was subsided immediately after the surgery. In order to improve the range of motion of the shoulder, physical therapy was performed when the surgical pain relieved. Two months after surgery full range of motion in shoulder was obtained. Histologic diagnosis was osteoid osteoma.
