RESUMO
The rationale for surgical treatment of tendinitis is to induce a modulation of the tendon cell-matrix environment by either promoting a renewed wound repair cycle or by the removal of aberrant tissue. The adequacy of healing as a result of surgical tendon treatment has been poorly documented histologically; what evidence exists suggests normal tissue is not achieved. The clinical experience of the authors as well as preliminary analysis of wound healing patterns in a longitudinal internal tenotomy rabbit tendo-Achilles model are discussed.

The authors prospectively evaluated the degree of contamination to the operating room team during 60 consecutive total joint arthroplasties. Each member of the team was required to wear a hood, mask, protective eyewear, and shoecovers. At the conclusion of each procedure, all members were assessed in terms of degree and location of contamination. One hundred percent of the surgeons and first assistants were exposed. The face and eyewear were noted to be the area of greatest contamination. The authors found orthopedic surgeons to be at significant risk of contamination with blood and body fluids during total joint arthroplasty.

In 34 patients with primary or metastatic tumors of the cervical spine over a ten-year period, the presenting symptom was neck pain. Eleven patients demonstrated evidence of radiculopathy, one a myelopathy, and three a combined myeloradiculopathy. Surgical stabilization, combined in eight cases with cord decompression, successfully relieved pain and prevented further neurologic deterioration in 17 of 18 patients with radioresistant tumors. Complications included two patients who were treated with short posterior fusions displacing as a result of tumors progressing above and below the fusion, and one patient in whom an anterior methacrylate mass became dislodged and appeared to jeopardize the esophagus. Methacrylate was used to augment the grafts posteriorly to facilitate early mobilization without the need for a halo splint. Mean patient survival was not significantly increased by surgical intervention (26 weeks vs. 20 weeks). While most lesions of the cervical spine can best be managed by nonoperative methods, in selected patients long posterior fusion with wires and methacrylate appears successful in relieving pain, halting progress of neurologic deficits, and facilitating early mobilization.

This paper describes a system for evaluation of ground-foot reaction forces in which multiple 1 centimeter diameter metal coated points transmit pressure to a photoelastic sheet. The pressure generates circular interference patterns, the diameters of which are linearly related to the pressure applied. The system permits the computerized construction of a three-dimensional contour map which can be compared to a pedobarograph. The qualitative/quantitative assessment system can identify areas on the plantar aspect of the foot at risk for skin breakdown. This information will permit treatment to proceed on a more rational basis than has been possible heretofore.
