Abstract

The temperature in the tibia and in the saw blade were recorded during 30 knee arthroplasty operations. In the saw blade the median maximum temperature was 68 degrees C (45-100 degrees C). The corresponding bone temperatures at two levels approximately 2 and 3 mm below the cutting surface were 47 degrees C and 42 degrees C, respectively. Irrigation of the saw area with physiologic saline solution had only a minimal effect. During the cement-curing process, the temperature was 37 degrees C (31-50 degrees C) at the cement-bone interface. We conclude that the cutting procedure generates heat above the critical temperature for bone necrosis that may harm prosthetic fixation, notably for bone ingrowth.

Total shoulder arthroplasty.

Surgeons perform total shoulder arthroplasty (TSA) procedures to reduce patients' intractable arthritic pain and to repair humeral head fractures. Total shoulder arthroplasty has undergone remarkable advances--not only in prosthetic improvements and refinements--but in patient outcomes. Advantages to TSA procedures include decreased pain and patients' increased ability to perform activities of daily living.

Biomechanical evaluation of a bioresorbable PLA dowel for arthroscopic surgery of the shoulder.

Metallic implants in the reconstructive surgery of the shoulder joint can lead to certain complications. Therefore, a small bioresorbable dowel made of PLA has been developed for arthroscopic refixation of the glenoid labrum. Biomechanical tests employing in vitro degradation should confirm the implant's viability before starting the clinical application. Pull-out experiments of sutures fixed with these dowels were performed. The bioresorbable implant fulfilled the mechanical expectation in its time-dependent stability under realistic conditions by far. A reliable fixation of sutures by the implant in clinical situations can be widely guaranteed with these experimental results.

Current status and imaging of allograft meniscal transplantation.

The authors present an overview of the current indications, techniques, results and complications of allograft meniscal transplantation. The radiologist's role in pre- and postoperative imaging is described. The spectrum of magnetic resonance imaging findings of meniscal allografts are illustrated.
