Randomized Controlled Trial Clinical Trial
The effect of postoperative wound drainage reinfusion in reducing the need for blood transfusions in elective total joint arthroplasty: a prospective, randomized study.
A prospective, randomized study was conducted in 24 patients using the Solcotrans Orthopaedic Drainage Reinfusion System (Smith & Nephew Richards Inc, Memphis, Tenn) for postoperative blood salvage in total joint arthroplasty. The amount of postoperative autologous blood salvage averaged 946 mL. ⋯ There were no transfusion reactions, infectious complications, or coagulopathies. Postoperative blood salvage is a safe, reliable, and effective source of autologous blood.

A prospective study was undertaken in 39 patients undergoing 48 foot and ankle procedures using intravenous regional anesthesia (IVRA). IVRA was administered using 35 cc of 0.33% or 0.5% lidocaine. Single tourniquets inflated to 250 mm Hg were used at the ankle level. ⋯ IVRA compared favorably with other methods of regional anesthesia in the lower extremity with respect to ease of technique, speed of onset, safety, and patient acceptance. However, it appears that it is less reliable than IVRA in the upper extremity. The reasons for this difference will require further investigation.

Ankle arthroscopy has rapidly become an important diagnostic and therapeutic procedure. Currently, indications for operative arthroscopy include transchondral talar dome fractures, acute articular fractures with hemarthrosis, posttraumatic synovitis, loose bodies, inflammatory synovitis, degenerative joint disease, and soft tissue impingement. Diagnostic arthroscopy is indicated for the patient with a chronically painful, symptomatic ankle when nonoperative treatment has failed and other measures have failed to produce a diagnosis. ⋯ The use of lasers in arthroscopy has yet to be clearly defined. The small size of the laser is an advantage in the ankle, but cost remains a disadvantage. Advances in technique and equipment will continue to expand the indications for this procedure.

Arthroscopy is a valuable technique used by the majority of orthopedic surgeons in practice. Complications in arthroscopy have been compiled on a formal basis since 1983. Several studies on complications are reviewed and summarized. ⋯ The most frequent type of complication encountered in arthroscopic surgery is hemarthrosis. The procedure with the highest complication rate is the lateral retinacular release. Technical considerations are discussed which would be useful in lessening the incidence of complications in arthroscopy.

Femur fractures in the pediatric population are common injuries which may be either isolated or associated with polytrauma. The orthopedist is faced with treatment options ranging from skin traction to more aggressive methods, including internal or external fixation. We review the pros and cons of current treatment options. A simple treatment algorithm based on age of the patient, other associated injuries, and open vs closed injury is presented.
