New concepts in arthroplasty of the hand and wrist.

Clinical trials with cemented polyethyiene and metal total joint arthroplasties were initiated in 1973. Replacements have been developed for the wrist, carpometacarpal joint of the thumb, metacarpophalangeal joints of the thumb and fingers, and the proximal interphalangeal joints of the fingers. Results, evaluated by pain relief and joint stability, were excellent at all sites. Motion, however, averaged only 50% of normal. Significant problems included abnormal posture in the wrist, roentgenographic evidence of loosening in the finger metacarpophalangeals, extensor lag in the metacarpophalangeal of the thumb, and lack of motion in the proximal interphalangeal joint of the finger.

Total wrist arthroplasty: a preliminary report.

Evaluation of 26 Meuli total wrist arthroplasties in 22 patients 7 to 17 months after operation revealed that 92 percent (24 wrists) were relieved of pain. Postoperative motion averaged 32 degrees of dorsiflexion. 27 degrees of palmar flexion, 2 degrees of radial deviation, and 23 degrees of ulnar deviation. Failure of the prosthetic design to place the center of rotation properly in the capitate resulted in a tendency toward flexion and ulnar deviation deformities. Reoperation was required in nine (35 percent) of the 26 wrists. After reoperation of these nine wrists, 77 percent (20 wrists) of the total group had good or excellent results, 11.5 percent (three wrists) fair, and 11.5 percent (three wrists) poor.

Current status of total joint replacement in the upper extremity.

The principles ot total joint arthroplasty recently have been expanded to the upper extremity, following the dramatic success with total hip and total knee replacement procedures. New problems have been encountered with the rebalancing of the soft tissues and the technical nature of joint mechanics in the upper extremities. Work on shoulder joint replacement is in the very early stages and of unknown success. Several prostheses are being used and tested. For elbow and wrist replacement, early and predictable success has been accomplished, enabling relief of pain and satisfactory motion. Total joint replacement in the fingers and thumb has provided excellent relief of pain but has been hindered by difficulties in rebalancing the soft tissues in patients with rheumatoid arthritis. It appears that total reconstruction of arthritic upper-extremity joints will be commonplace in the not-too-distant future. Clinical trials are being expanded, with increasing success.

Results after hemiarthroplasty of the hip using a cemented femoral prosthesis. A review of 109 cases with an average follow-up of 36 months.

Hip arthroplasty using the Thompson femoral prosthesis with methyl methacrylate fixation was performed on 109 hips in 106 patients. During an average follow-up period of 36 months, 26 patients died. Fifty-one procedures were performed for fresh fractures of the femoral neck and results were satisfactory in this group provided the patient was minimally active. Results were unsatisfactory in patients who had idiopathic avascular necrosis (18), painful, failed noncemented prostheses (6), and osteoarthritis (3). In these last three groups, one-half required conversion to total hip arthroplasty and an additional one-third had pain. Reoperation was required in 22 cases. Intraoperative death occurred in one elderly patient after insertion of cement. Results suggest that the primary indication for this procedure is in the minimally ambulatory or nonambulatory elderly osteoporotic patient who has a fresh fracture of the femoral neck.

Total arthroplasty of the wrist to relieve pain and increase motion.

Total joint arthroplasty of the wrist is a feasible and satisfactory solution to the problems of patients who have significant wrist pain or severe limitation of motion, or both. It is particularly useful in patients with rheumatoid arthritis or with post-traumatic or degenerative arthritis of the wrist. In geriatric patients, this procedure appears to be a satisfactory alternative to wrist joint arthrodesis. Proper placement of the device and proper surgical technique to simulate the normal balance and motion of the wrist are necessary.

Review and analysis of silicone-rubber metacarpophalangeal implants.

A series of 530 consecutive arthroplasties using silicone-rubber implants in 119 patients was reviewed. Clinical and roentgenographic evaluations were completed on sixty patients and 254 implants, with an average follow-up of two and a half years; the remaining fifty-nine patients were evaluated by questionnaire. All but three patients had rheumatoid disease, usually with severe deformity, and many of the patients underwent other procedures on the upper extremity; these procedures often precluded early motion after the arthroplasties. Three prostheses (0.6 per cent) were removed because of infection, and reoperation was required in 2.4 per cent of the joints. Detailed clinical follow-up of 254 prostheses revealed the following: for Swanson prosthesis-average motion 38 degrees, fracture rate 26.2 per cent, and recurrence of clinical deformity 11.3 per cent; for Neibauer prostheses-average motion 35 degrees, fracture rate 38.2 per cent, and recurrence of clinical deformity 44.1 per cent. It should be noted that use of early implant types and some variations from the designer's recommended rehabilitation protocols were features of this series.

Complications of total hip arthroplasty treated by reoperation.

In a series of 3,204 consecutive total hip arthroplasties performed on 2,684 patients at the Mayo Clinic from March 1, 1969, through February 28, 1972, reoperation for a complication was necessary in 125 hips (3.9 per cent). The complications, in order of frequency, were infection, dislocation, trochanteric problems, ectopic bone, and loosening of the femoral prosthesis. There were less frequent complications that also required further surgery. Attention to specific technical details is the most important means of avoiding a complication that requires reoperation.

Total wrist arthroplasty. Problems with implant failures.

Prosthetic replacement of the wrist requires careful consideration of anatomic and mechanical factors, appreciation of the techniques of implant fixation, and recognition of soft tissue imbalance across the wrist. Cemented wrist implants have an unacceptably high rate of failure (15%-30%) with a five-year progressively decreasing prosthesis "survival rate." Three different implant designs have been studied and analyzed with respect to long-term success. In the revision of failed wrist implants, the surgeon must evaluate requirements for a stable wrist and appropriately reconsider resection, a more stable total joint arthroplasty, and wrist arthrodesis.

Fifty-year trend in hip fracture incidence.

During the 50-year period 1928 to 1977, 1,250 Rochester, Minnesota residents experienced 1,355 proximal femur (hip) fractures. The incidence of these fractures appeared to rise during the first 15 years of the study, but this was most likely due to underascertainment of cases in the early period since there was no evidence of a cohort effect. From 1943 onward, there was no significant increase in the incidence rates which remained relatively level for total hip fractures, initial hip fractures alone, and for initial hip fractures due to moderate trauma. Thus, we found no evidence to support the contention that hip fracture incidence has risen dramatically in recent years. Secular changes in incidence cannot account for the observation that hip fracture rates in Rochester are greater than those reported from earlier population-based studies.
