Direct anterior approach to the hip joint utilizing a curved transverse skin incision and splitting the tensor fascia muscle longitudinally provides an effective exposure for carrying out primary total hip arthroplasty. Excellent visualization of the acetabulum is afforded by this direct approach. Modified femoral rasps of varying lengths are employed to(More)
Metastatic lesions to the bones of the foot occurred in three elderly patients. Biopsy established the diagnosis in a 90-year-old woman. In a 72-year-old man and a 79-year-old man, the diagnosis was possible from roentgenographic features. In the latter, biopsy of an additional osseous metastatic site established the diagnosis. A thorough review of the(More)
Metacarpals, metatarsals, and phalanges were studied to assess the developmental morphology of “secondary” ossification in the “nonepiphyseal” ends of these bones as well as the formation of the pseudoepiphysis as an epiphyseal ossification variant. Both direct ossification extension from the metaphysis into the epiphysis and pseudoepiphysis formation(More)
Retrospective analysis of 48 medial epicondylectomy procedures in 46 patients demonstrated that symptomatic and objective improvement was usual. Most patients experienced improvement of symptoms (98%) and moving two-point discrimination (87%), and many demonstrated improved motor strength (54%). By use of the McGowan scheme for grading ulnar neuropathy, 92%(More)
This study investigated the relative roles of the interosseous membrane (IOM) and triangular fibrocartilage complex (TFCC) in the transmission of force from the hand to the humerus. Our findings suggest a spectrum of forearm destabilizing injuries. The intact radius abutting the capitellum provides the primary restraint to proximal migration of the radius.(More)
The relative importance of the three major periscaphoid ligament complexes in maintaining the normal radiocarpal articulation was assessed. Pressure-sensitive film recorded the changes in radioscaphoid and radiolunate articular contact that occurred with sequential ligament sectioning in 12 cadaver wrists. Alterations in the radiocarpal articular contact as(More)
Direct ossification extending from the metaphysis into the epiphysis preceded and continued to be more mature than formation and expansion of the typical epiphyseal ossification center at the opposite end of each longitudinal bone of the hand and foot. Direct metaphyseal to epiphyseal ossification usually started centrally and expanded hemispherically,(More)
The mechanical strength of the human radius and ulna depends on their geometrical and material properties. This study quantifies the cortical bone cross-sectional properties of the adult radius and ulna (cross-sectional area, thickness, centroids, area moments of inertia and section moduli) using computerized tomographic (CT) scanning coupled with image(More)
A case of a displaced coronal fracture of the hamate body with a 1-month delay in diagnosis is presented with a review of the literature regarding hamate-body fractures. Mechanism, diagnosis, and treatment options are discussed. This diagnosis should be suspected on initial review of plain radiographs, which must include an oblique view in any patient(More)
Radial and ulnar longitudinal deficiencies are the 2 most common types of congenital longitudinal deficiencies of the arm, with radial deficiency being 3 to 4 times more common. They are a spectrum of abnormalities, ranging from mild deficiency of the digits to complete loss of one-half the forearm, wrist, and fingers. Radial longitudinal deficiency is(More)
