This paper examines the expected complexity of boundary problems on a set ofN points inK-space. We assume that the points are chosen from a probability distribution in which each component of a point is chosen independently of all other components. We present an algorithm to find the maximal points usingKN + O (N1−1/K log1/K N) expected scalar comparisons,(More)
Many of the current techniques of internal fixation of proximal humerus fractures use tension band wires to achieve secure fixation, allowing immediate postoperative exercise of the affected limb. In addition, the use of a cancellous lag screw placed from the humeral shaft into the humeral head may have several advantages. In particular, this lag screw does(More)
The unstable hip can be diagnosed in newborns with acceptable accuracy. The following factors are associated with the newborn unstable hip: female preponderance, breech presentations, cesarean section deliveries, first borns, left hip involvement, the Caucasian race, and increased birth weight. These findings suggest that the newborn unstable hip is(More)
This paper presents the short term results of an ongoing prospective randomized trial comparing a cemented unipolar with a cemented bipolar hemiarthroplasty for the treatment of displaced femoral neck fractures in the elderly. Forty-seven patients with an average age of 77 years completed 6-month followup. Outcomes at 6 weeks, 3 months and 6 months were(More)
A long-term follow-up in 15 patients who had juvenile idiopathic scoliosis was instituted to determine the efficacy of a part-time Milwaukee brace program. The patients were divided into two groups. In Group I patients, part-time bracing was successful in controlling the scoliosis. The average curvature at the onset of bracing was 32 degrees, and the final(More)
From 1966 to 1983, 11 females and eight males with spinal muscular atrophy were treated by arthrodesis. Seventeen of 19 patients were evaluated by follow-up physical examination, roentgenograms, and questionnaires. In order to compare long-term versus short-term results, changes in management, and factors contributing to morbidity and mortality, three(More)
On May 1, 1999, the Hospital for Special Surgery was 136 years old. To present a history that does adequate justice to the many people, who have been or still are involved in the making of it, is an impossible task. Nevertheless, this document is important because the hospital, first under the name of Ruptured and Crippled and then under that of Special(More)
Axial computed tomographic scans were used to guide percutaneous needle biopsies in 76 patients with thoracic and lumbar spinal lesions. Prebiopsy evaluation included spine radiographs, radionuclide bone scans, computed tomographic scans, magnetic resonance imaging scans in some cases, and coagulation studies. Forty-five patients were diagnosed as having(More)
Of eighty-five consecutive patients, thirteen to twenty years old, with spastic cerebral palsy involving one or both extremities (thirty-five patients seen at one institution and fifty, at another), four had roentgenographic evidence of fragmentation of the distal pole of the patella. In addition, three other patients with six spastic lower extremities,(More)
Thirty-five patients who were to have posterior spinal arthrodesis, total hip arthroplasty, or total knee arthroplasty were entered into one of two groups: Group A, to receive unwashed, filtered sanguineous drainage from the wound, or Group B, to receive washed, filtered drainage. The purpose of this prospective study was to evaluate the safety, efficacy,(More)
