Incisional biopsy and intramedullary pinning were performed for pathological fracture associated with a malignant bone tumor of the proximal humerus. Osteosarcoma, for which preoperative chemotherapy had been performed, was confirmed by postoperative pathological examination. To achieve wide resection and acquire a safe resected margin, total humerus replacement was performed, and the whole hum...

Introduction. Enchondroma protuberans is an extremely rare benign cartilaginous bone tumor. We report the first case report of enchondroma protuberans in the forearm. Presentation of Case. We report a case of enchondroma protuberans originating in the left ulnar bone of a young woman. A 20-year-old female referred to our hospital complaining of progressive sustained left forearm pain with a rad...

BACKGROUND Cervical myelopathy (CM) is a clinical diagnosis that may be associated with hyperintense areas on T2-weighted magnetic resonance imaging (MRI) scan. The use of contrast enhancement in such areas to differentiate between neoplastic and degenerative disease has rarely been described. CASE DESCRIPTION We present a 41-year-old female with a 5-month course of progressive CM. The cervic...

AIM: The authors discuss the current management of intramedullary spinal cord tumors in children and young adults. Intramedullary spinal cord tumors of the pediatric population are rare and comprise only a small percentage of all central nervous system neoplasms. There has been much controversy with the surgical management of these tumors. METHODS: The majority of these neoplasms are histologic...

Gerhard Kuntscher [1] first recognized that placing larger intramedullary devices enhanced the healing of long bone fractures. By the mid-1950’s he had adopted motorized reaming as a standard part of his technique. However, he also recognized that intramedullary fat could be a source of potentially fatal embolus if introduced systemically. To avoid this complication, he recommended over sizing ...

In visual search, some fixations are made between stimuli on empty regions, commonly referred to as "centre-of-gravity" fixations (henceforth: COG fixations). Previous studies have shown that observers with task expertise show more COG fixations than novices. This led to the view that COG fixations reflect simultaneous encoding of multiple stimuli, allowing more efficient processing of task-rel...

Intramedullary nailing is one of the most convenient biological options for treating distal femoral fractures. Because the distal medulla of the femur is wider than the middle diaphysis and intramedullary nails cannot completely fill the intramedullary canal, intramedullary nailing of distal femoral fractures can be difficult when trying to obtain adequate reduction. Some different methods exis...

Intramedullary spinal schwannomas are rare benign spinal cord tumors and are easily misdiagnosed because of the imaging characteristics shared with intramedullary glioma. Correct preoperative definitive diagnosis is essential for treatment and prognosis. To improve the preoperative diagnostic strategy, clinical and imaging data of seven patients with intramedullary spinal schwannoma (6 men, mea...

Primary hyperparathyroidism revealed by a pathological fracture is very uncommon. We present a case of a 54-year-old female patient who was admitted with fracture of her right femur. She underwent closed intramedullary reconstruction nailing with bipolar locking. The pathological findings confirmed the diagnosis of primary hyperparathyroidism with brown tumor. Further tests showed increased bot...
