Bilateral locked posterior fracture dislocation of the shoulders is one of the least common injuries of the shoulder, and this injury has been suggested to be pathognomonic of seizures when diagnosed in the absence of trauma. The authors present a case of idiopathic bilateral locked posterior fracture dislocations of the shoulder, along with a review of the(More)
The influence of muscle activity and forearm position on the stability of the lateral collateral ligament deficient elbow was investigated in vitro, using a custom testing apparatus to simulate active and passive elbow flexion. Rotation of the ulna relative to the humerus was measured before and after sectioning of the joint capsule, and the radial and(More)
The objectives of this study were (1) to determine the most advantageous screw locations within the humeral head when plate and screw fixation is to be used and (2) to determine the effect of positioning the screw tip abutting the subchondral bone. Ten paired humeral heads were harvested with a monoplanar cut through the anatomic neck. Through use of a(More)
Measurement of lateral rotation range of motion (ROM) is frequently performed during shoulder evaluation. The purpose of this study was to determine the intratester and intertester reliability of goniometric measurement of passive lateral rotation ROM of the shoulder. Two experienced PTs performed the testing in a randomized block design. They were blinded(More)
The formation of a painful neuroma after operations on the medial or lateral sides of the elbow is a common problem. Our aim was to determine the relationship of the cutaneous nerves to the three usual skin incisions around the elbow. In 18 freshly frozen cadaver arms we made three standard 16 cm incisions in the skin medially, laterally, and posteriorly(More)
The objective of this study was to determine the effect of screws and keel size on the fixation of an all-metal glenoid component. A prototype stainless-steel glenoid component was designed and implanted in 10 cadaveric scapulae. A testing apparatus capable of producing a loading vector at various angles, magnitudes, and directions was used. The independent(More)
BACKGROUND AND PURPOSE Findings related to joint function can be recorded with movement diagrams or by characterizing the "end-feel" according to the procedure described by Cyriax. Because both methods are used to classify pain and resistance in relation to joint range of motion (ROM), the purpose of this study was to simultaneously evaluate the reliability(More)
The purpose of this investigation was to determine the strength and mode of failure of a plate specifically designed for wrist arthrodesis. An eight-hole plate was constructed with a solid central portion and a distal taper. Four 2.7 mm screws were used in the distal (metacarpal) portion of the plate. Four 3.5 mm screws were used in the proximal (radius)(More)
