The risk of deep venous thrombosis: a computerized epidemiologic approach.

The appropriate use of prophylactic measures to prevent deep venous thrombosis is dependent on the ability of physicians to identify high-risk patients. This problem has been the subject of numerous epidemiologic reports compiled during the last several decades. Described herein is a computerized technique to condense the literature on this subject into a form better suited for practical application. This technique comprises an interactive program that calculates a patient's relative risk of developing a thrombus on the basis of a comparative evaluation of his medical profile. The computer then reports the patient's calculated relative risk along with other information that may pertain to his risk of deep venous thrombosis.

A pedicle bone grafting procedure for failed lumbosacral spinal fusion.

An iliac crest bone graft with an intact quadratus lumborum muscle pedicle was devised for the surgical repair of symptomatic pseudarthroses in failed lumbosacral spinal fusions. The graft and pedicle are rotated into a paraspinous bed and internally fixed to the spine. The preliminary results are presented in 12 patients in whom operations were performed under the direction of a single surgeon. The follow-up periods averaged 39 months (range, 8-68 months). Eleven patients demonstrate radiologic evidence of union, and nine subjectively report improvement of symptoms. Five complications occurred in four patients. Two superficial infections quickly resolved with appropriate therapy. One patient had neural foraminal encroachment from an internal fixation device, necessitating its early removal. In a fourth patient major complications of a deep infection and an incisional hernia were successfully treated. Iliac pedicle grafting is an alternative stabilization procedure for use in a select group of patients with disabling pain and previous failed spinal fusion.

Cyclic sequential compression of the lower limb in prevention of deep venous thrombosis.

Patients undergoing operations on the hip for either replacement or fracture were chosen for this study. Fifty-two subjects received cyclic sequential compression as well as elevation of the lower limb while another fifty-two patients were treated with only elevation of the lower limb. No other method of prophylaxis for deep venous thrombosis was employed during the study period. Support stockings were used after removal of the compression device. Doppler ultrasound, phleborheography, and, when possible, radioiodinated fibrinogen scanning were used for identification and location of thrombi. A deep-vein thrombosis developed in ten patients (19 per cent) in the control group and in only one patient (2 per cent) in the group that was treated with compression. This difference is statistically significant (p less than 0.05).

Cineradiography of the braced normal cervical spine. A comparative study of five commonly used cervical orthoses.

Five orthotic devices were selected for a study of their effectiveness in immobilizing the cervical spine. These orthoses were fitted to subjects with a normal range of motion of the cervical spine. Motion pictures were made from a lateral view while the patient actively flexed and extended his cervical spine as well as from the frontal view with the patient rotating to each side and bending to each side. The soft cervical collar offers very little immobilization. The firm plastic Thomas collar restricts about 75 per cent of flexion-extension, rotation and lateral bending. The four-poster orthosis gave 80 to 85 per cent restriction of flexion-extension and lateral bending but only restricted 60 per cent of rotation. The long two-poster cervical orthosis caused 90 to 95 per cent restriction of all motions. The Guilford two-poster cervical orthosis restricted 90 per cent of all motions.

The Minnesota Multiphasic Personality Inventory: general guidelines to its use and interpretation in orthopedics.

The MMPI is a valuable source of additional information for the orthopedist faced with trying to manage patients who may have hysterical or hypochondriacal tendencies. The presence of elevations on scales 1 (hypochondriasis) and 3 (hysteria) markedly reduces the chances for successful therapeutic intervention, whether it be surgical or conservative. A clinical interview by a psychologist in conjunction with the MMPI has improved diagnosis and management programs for patients with low back pain.
