A method for directly measuring the position of the humeral head on the face of the glenoid in different positions of abduction of the arm was developed. We studied three subject groups: 12 patients with normal shoulders (group 1), 15 patients with stage II impingement syndrome (group 2), and 20 patients with rotator cuff tears or stage III impingement… (More)
Achieving bony union and early weight bearing in peritrochanteric femur fractures poses a continuous challenge for the orthopedic surgeon. Current standards of surgical fixation for the myriad possible fracture patterns include the compression hip screw (CHS), the 90 degrees/95 degrees blade plate, and locked intramedullary nails. The gamma nail (GN) was… (More)
The incidence, basic pathophysiology, and clinical and radiologic examination in posterior instability of the shoulder are discussed. Conservative treatment protocols and surgical procedures are presented.
Of forty-four patients who were treated by arthroscopic acromioplasty from July 1984 through August 1986, forty were available for analysis. The average age was 43.2 years, and 86 per cent of them had participated regularly in sports but were disabled due to symptoms of impingement. All patients had had a minimum of six months of non-operative therapy. The… (More)
Articular contact pressures in ten cadaveric knees with intact ligaments were measured with the use of film and a model that simulated non-weight-bearing resistive extension of the knee. The measurements were repeated after sequential sectioning of the posterior cruciate ligament and the posterolateral complex (the posterolateral capsule, the popliteus… (More)
Current concepts for the diagnosis and treatment of anterior dislocation and subluxation, including classification of injuries, are presented. The pathophysiology, clinical and radiologic examination, and treatment protocols are discussed.
Acute immobilization is associated with rapid loss of bone. Prevailing opinion, based on population cross-sectional data, assumes that bone mass stabilizes thereafter. In order to address whole-body and regional skeletal mass in long-term immobilization, monozygotic twins were studied, one of each twin pair having chronic spinal cord injury (SCI) of a… (More)
This article contains a report of the results of a study of 10 postmenopausal women with uncomplicated osteoporosis who were treated with sodium fluoride, calcium supplementation, and vitamin D. Spinal fractures ceased by 18 months, trabecular bone mass increased 26 per cent per year, and patients reported symptomatic improvement.
Abnormalities in platelet number and function have been described in patients with homozygous sickle cell disease (SS), suggesting that platelets play a role in this disorder. We studied platelet shape and circulating platelet aggregates (AGG) in SS patients as a guide to in vivo activation. One drop of freely flowing blood was collected by venipuncture… (More)
