In vivo bone strain experiments were performed on the ulnae of three female rhesus macaques to test how the bone deforms during locomotion. The null hypothesis was that, in an animal moving its limbs predominantly in sagittal planes, the ulna experiences anteroposterior bending. Three rosette strain gauges were attached around the circumference of the bone(More)
A phylogenic review shows the DRUJ to be a highly evolved and specialized structure. The diarthrodial joint, in combination with the TFCC, ligament complex, and oblique fibers of the distal interosseous membrane, permit rotation while preserving stability and transmitting the load borne by the radiocarpal joint to both bones of the forearm. Our improved,(More)
Malunions are a well-recognized complication of pediatric supracondylar humeral fractures. Results of corrective osteotomies vary, and complication rates have been reported to be as high as 40%. Considering the high rate of complications for malunion correction, we investigated the feasibility of arthroscopy. We present a technique for arthroscopic(More)
BACKGROUND Elbow posteromedial rotatory instability (PMRI) is known to occur with fracture of the anteromedial coronoid and injury to the posterior bundle of the medial ulnar collateral ligament (pMUCL). However, whether instability results from isolated pMUCL injury remains unclear. The purpose of this study was to quantify displacement about the(More)
BACKGROUND The purpose of this study was to evaluate 30-day postoperative complications of open reduction and internal fixation [ORIF] and total elbow arthroplasty [TEA] for the treatment of distal humerus fractures in elderly patients using a validated national database. METHODS Review of the National Surgical Quality Improvement Program (NSQIP) Database(More)
Word Sense Disambiguation is a formal way of saying, " Which dictionary definition is correct in context? " Humans are adept at extracting the context of a sentence and applying it to every word. If the sentence is " I like to swim next to the river bank, " then the word " bank " means " sloping land " and does not mean " a financial institution. " Humans(More)
