Pseudomalignant osseous tumor of soft tissues is a rare tumor of the hand. Histopathologic differentiation of this benign lesion from malignant lesions is difficult because mitotic figures are common in typical cases, but bizarre pleomorphic and hyperchromatic nuclei never occur. Wide excision is adequate in most cases, but ray resection is indicated when(More)
A case of metastasis to the patella from adenocarcinoma of the lung is reported. The clinical presentation was similar to septic arthritis of the knee. Histopathologic examination established the metastatic nature of the lesion; this is the first case in which a patellar lesion was the only evidence of distant metastasis. Metastatic tumors of the patella(More)
Fourteen patients with fracture of the capitulum of the humerus were treated, ten by excision of a large fragment or multiple small fragments. Their results were superior to those in patients treated either by closed reduction or by open reduction and fixation. Nine had good to excellent retention of elbow motion, six had no pain, and three had minimum(More)
We reviewed 13 cases of osteochondritis dissecans of the patella followed-up for 18 months to 19 years. Two were treated conservatively with excellent results, and 11 by operation with six excellent, four good and one fair result. There was complete radiographic healing of the defect in 10 cases and partial healing in three. The size of the osteochondritic(More)
BACKGROUND One criticism of current video systems for endoscopic surgery is that two-dimensional (2D) images lack depth perception and may impair surgical dissection. To objectively measure the efficacy of 3D endoscopy, we designed a training model with specific tasks to show potential differences between 2D and 3D endoscopy. Its clinical value was then(More)
OBJECTIVES/HYPOTHESIS Preferred treatment of oral/plunging ranulas remains controversial. We present our experience with ranulas at the University of North Carolina (UNC) and review the literature. METHODS Retrospective review. From 1990 to 2007, 16 oral ranulas and 10 plunging ranulas were treated at UNC. Combining the UNC series with the literature(More)
BACKGROUND Limb length discrepancy and its effects on patient function have been discussed in depth in the literature with respect to hip arthroplasty but there are few studies that have examined the effect on function of limb length discrepency following total knee arthroplasty (TKA). The aim of this study was to determine whether limb length discrepancy(More)
OBJECTIVES To use immunohistochemical (IHC) evaluation of proteins encoded by genes that were differentially expressed in follicular thyroid adenomas (FAs) vs follicular thyroid carcinomas (FTCs) to distinguish benign vs malignant follicular thyroid lesions. Multiple gene microarray studies suggest that benign and malignant follicular thyroid neoplasms have(More)
