Total ankle arthroplasty: a unique design. Two to twelve-year follow-up.

We evaluated the intermediate-term results of a novel total ankle arthroplasty that includes insertion of the components without cement and arthrodesis of the tibiofibular syndesmosis as part of the operative procedure. One hundred consecutive Agility ankle replacements were performed in ninety-five patients between 1984 and 1993. At the time of follow-up, eighty-three patients (eighty-six ankles) were alive and twelve patients (fourteen ankles) had died. Five (6 per cent) of the eighty-six ankles in the living patients had been revised. Including the components that had been revised for loosening, twenty-one (twelve tibial and nine talar) components had migrated. Delayed union of the syndesmosis (twenty-eight ankles) and non-union of the syndesmosis (nine ankles) were associated with the development of lysis around the tibial component. Non-union of the syndesmosis was also associated with migration of the tibial component and circumferential radiolucency around that component. In addition to the patients who died, one patient had a resection of the implant with subsequent arthrodesis. The remaining eighty-two patients (eighty-five ankles) were the basis for the clinical evaluation in the study. The average age at the time of the procedure was sixty-three years (range, twenty-seven to eighty-one years). At the time of the most recent follow-up (range, 2.8 to 12.3 years; average, 4.8 years), forty-seven (55 per cent) of the remaining eighty-five ankles were not painful and twenty-four (28 per cent) were only mildly painful. The range of motion of the fifty-six ankles that were examined at the time of follow-up averaged 36 degrees (range, 10 to 64 degrees), and the results for seventy-nine (93 per cent) of the eighty-five ankles were satisfactory to the patients.

Total ankle arthroplasty: new concepts and approaches.

A new type of total ankle arthroplasty developed with the use of a CAD-CAM computer was used in a series of 27 ankles between 1985 and 1989. Follow-up in 19 ankles ranging from 18 months to 5.5 years postoperatively indicates that the design of this implant appears to avoid the problems of subsidence and malleolar impingement. Based upon the results in this series, it appears that the best candidates for use of this type of total ankle implant are patients with rheumatoid arthritis.

UCI/RAM total knee arthroplasty: a ten-year review.

This study covers a ten-year period of UCI/RAM total knee arthroplasty (Dow-Corning-Wright). Two hundred twenty-nine knees out of 516 done during this period were evaluated in an office setting. Additionally, 70 mail responses were obtained, and 52 patients were found to be deceased. This gives a 68% followup of all cases done during this period. Surgical technique, postoperative course, functional results, and complications are reviewed.

Postoperative ulnar-nerve palsy. Are there predisposing factors?

In a prospective study in which we attempted to identify the etiology of postoperative ulnar-nerve palsy, 6,538 patients were followed through surgery and convalescence. In seventeen patients (0.26 per cent), an ulnar-nerve palsy developed at varying times during the postoperative period. Of these seventeen patients, all were re-evaluated at an average of six months and eleven were re-evaluated at an average of three and one-half years after operation. Bilateral nerve-conduction studies were done on all seventeen patients during the initial visit and on five of the eleven who were re-evaluated at an average of three and one-half years. Abnormal slowing of the conduction times was found in both nerves, suggesting a possible predisposition to this condition. Based on the results of the study, it is suggested that many patients may have a subclinical ulnar neuropathy that may become symptomatic as a result of the many maneuvers and manipulations that are associated with surgical procedures.

Peg and dowel fusion of the proximal interphalangeal joint.

The clawtoe or hammertoe deformity if frequently encountered in office practice. The etiology of this condition remains obscure, although intrinsic atrophy or imbalance was suspected as early as 1863 by Duchenne. Arthrodesing the proximal interphalangeal joint converts the more powerful flexor tendon to a flexor of the metatarsophalangeal joint, thereby alleviating pressure on the metatarsal head and distributing the weight more evenly on the forefoot. Arthrodesing is accomplished by the peg and dowel method, with the fourth toe presenting the most technical difficulties. An extensor tenotomy or dorsal capsulotomy of the metatarsophalangeal joint is frequently necessary to realign the toe with the corresponding metatarsal ray. A collodion dressing is used to immobilize the toe for a period of 4 to 6 weeks, with a fusion rate of 97% in 73 toes. All patients were contacted, with 87% responding favorably and stating that they had relief of their pain and were able to resume wearing normal footwear.
