Joint surgery for rheumatoid arthritis.

The state of the art in the surgery of rheumatoid joint disease is discussed with emphasis on guidelines for choosing the patients and the types of procedures available. Strong-willed, strong-boned, strong-muscled, and well-informed patients are the best candidates. Synovectomy is particularly useful in the minimally erosive stages of the disease when the active synovitis is not suppressed by one or more steroid injections or other modalities of therapy. Arthrodeses and arthroplasties are midstage procedures that are now being supplanted by total joint replacement. This is especially true of the knee, but new prostheses for elbows, shoulders, wrists, and ankles are on the horizon.

Retrospective analysis of surgical treatment of hallux rigidus/limitus: clinical and radiographic follow-up of hinged, silastic implant arthroplasty and cheilectomy.

Many authors have hypothesized on the etiology of hallux limitus and have proposed grading systems for classifying the degree of first metatarsophalangeal joint derangement and dysfunction. Several opinions exist regarding surgical treatment, should a patient fail with conservative therapy. Hinged, Silastic implant arthroplasty and cheilectomy account for a significant proportion of procedures accomplished. However, little follow-up documents and critically analyzes the long-term results of these procedures. This study analyzes, retrospectively, the results of these procedures with a minimum follow-up of 46 months. Hinged, Silastic implant arthroplasty appears to be a safe, technically easy, efficacious procedure in the grade II to III lesion in patients of 60 years or older, in whom an active life-style is desired. Cheilectomy appears to be indicated in the patient with a classic grade I lesion, while its use in grade II lesions, especially in the presence of sesamoid disease, requires further investigation.

[Etiology and pathogenesis of synovitis villonodosa pigmentosa].

Articular pigmented villonodular synovitis is a benign synovial disease of unknown etiology. It is a proliferative disorder of the synovium that can involve the joints, tendon sheaths, and bursae. There is a predilection for involvement of the lower extremities, particularly the knees. There are two histologically similar lesions of pigmented villonodular synovitis: "nodular" and "diffuse" pigmented villonodular tenosynovitis. The typical clinical course consists of progressive and painful swelling of the involved joint. Cystic erosions without sclerosis and invasion of adjacent bone from intra-articular synovial lesions are the typical roentgenographic manifestations. The surgical treatment of the lesions is discussed. A review of the literature is given and our own material on 47 patients is presented to illustrate the different features of the disease.

The Herbert total knee replacement: a longer than three year follow-up.

Thirty personally performed Herbert total knee replacements, evaluated during a 3-year follow-up, were found not to function well. At the end of one postoperative year 6 knees had symptomatic metal synovitis and required replacement. By the end of 3 years the Herbert total knee replacement had functioned in only 12 patients. The largest single follow-up complication was foreign body synovitis, inflammation of the synovium secondary to small free metal fragments produced by the 2 components rubbing against each other during gait.

Surgical treatment of arthritis in the elderly.

Arthritis in the elderly can be very effectively treated by a combination of careful orthopaedic and rheumatological assessment. The overall functional assessment, and definition of the aims and likely results of surgical treatment by the team approach, involving occupational therapists, physiotherapists and social workers, are important for success. There are many worthwhile surgical procedures available to relieve pain, and restore mobility and independence to those affected by osteoarthritis and rheumatoid arthritis.

Lesser metatarsophalangeal joint implants.

A double-stemmed MTP joint silastic implant has been described that acts as a flexible spacer for a number of pathologic conditions that affect the lesser metatarsophalangeal joints. Preliminary results suggest that this is a feasible alternative to joint destructive procedures with advantages over previously described implants.

[Current knowledge and future perspectives of cementless endoprosthetics].

The current problems facing the clinician, regarding young patients whose hips and knees have completely deteriorated, involve a return to function, as well as a longer life for the prosthesis than that rendered by cement fixation. The alternatives to cemented primary fixation devices have not yet with stood the test of time. In addition, when aseptic loosening of cemented prostheses occurs, cemented revisions have already demonstrated a high failure rate after a short-term follow-up, particularly in the hip. A follow-up period of up to 6 years for a cementless total knee and a short-term follow-up for a cementless hip (up to 3 years), using a porous metal bone contact surface, have shown very satisfactory clinical results in primary total hip and knee prostheses and revision of the total hip without the use of bone cement. These early results justify continuation of this clinical trial.

Short-term preventive antibiotics.

In a study of the duration of antibiotic prophylaxis in elective surgery, 466 procedures were surveyed over a four-year period. It is difficult to prove the efficacy of antibiotic prophylaxis when the rate of infection is so low, and, although not statistically significant, there is no difference in the infection rate whether the antibiotics are given intraoperatively only or for 48 hours, three days, or seven days. Per 100,000 patients, the cost savings of giving antibiotics intraoperatively rather than for 48 hours would have been $7,700,000; with the reduction from seven days to one-dose antibiotics, the savings would have been $29,700,000.
