Subtalar joint arthrodesis.

Forty patients (12 men and 28 women) treated with isolated subtalar joint arthrodesis were retrospectively reviewed. The average patient age was 50 years (range, 21-76 years). Preoperative diagnoses included posterior tibial tendon dysfunction, post-traumatic arthritis, nontraumatic arthritis, and subtalar joint middle facet coalition. The average follow-up was 15 months (range, 12-74 months). Subjective postoperative questionnaire results were classified as satisfied (n = 32), satisfied but with reservations (n = 4), or dissatisfied (n = 4). Eighty-three percent of the patients (n = 33) stated that they would undergo the procedure again. Minor complications (those that resolved with nonoperative treatment) occurred in 55% of the patients. However, the major complication rate was only 12.5%. This study showed no statistical correlation between the preoperative diagnosis and the postoperative outcome. Our results also suggested that the prevalence of complications is slightly higher than in previous reports. Isolated subtalar joint arthrodesis is an effective treatment for pain and deformity of the rearfoot.

Tibiotalocalcaneal arthrodesis with retrograde intramedullary nailing.

Nineteen patients (20 feet) with severe hindfoot and ankle deformity underwent tibiotalocalcaneal fusion with a retrograde locked intramedullary nail as a limb-salvage procedure. The purpose of this study was to compare the complication rates of this procedure in diabetic versus nondiabetic patients. There were 8 men and 11 women with preoperative diagnoses including Charcot neuroarthropathy, primary osteoarthritis, rheumatoid arthritis, equinocavovarus, posttraumatic osteoarthritis, gouty arthritis, and ankle malunion. Ten of 20 procedures were performed in patients with diabetes. The average patient age was 56 years, and the average postoperative follow-up was 19.8 months. Nineteen of 20 ankles (95%) achieved successful fusion with an average time of 4.1 months. Four patients (21%) required either a fracture brace or an ankle foot orthosis at final follow-up. Five patients (25%) had major complications and 11 patients had minor complications. Major complications included osteomyelitis (n = 2), Charcot arthropathy (n = 2), failure of fixation (n =1), soft-tissue necrosis (n = 1), cardiac arrest (n = 1), cerebral vascular accident (n = 1), and fatal pulmonary embolus (n = 1). All patients with major complications were diabetic, and 14 of 20 combined major and minor complications occurred in patients with diabetes. The complication rate was found to be high in diabetic patients with end-stage deformity undergoing a limb salvage

Peroneal tendon tears: a retrospective review.

Tears of the peroneal tendons are not uncommon but remain an underappreciated source of chronic lateral ankle pain. The purpose of this study was to identify the typical patient profile and nature of the injury, to analyze the course of treatment, and to determine the prevalence of complications seen with surgical repair. Forty patients with chronic pain over the peroneal tendons from the Foot and Ankle Institute at the Western Pennsylvania Hospital underwent peroneal tendon repair. During a 3-year period, a retrospective review was performed by evaluating medical records, surgical reports, and radiographs. The average patient age was 42 years (range, 13 to 64 years). The most common cause was an ankle sprain or other traumatic injury (58%). Peroneus brevis tears (35 patients; 88%), peroneus longus tears (5 patients; 13%), combined peroneus brevis and longus tears (15 patients; 37%), low-lying peroneus muscle belly (13 patients; 33%), lateral ankle ligamentous disruptions (13 patients; 33%), and peroneal subluxation (8 patients; 20%) were identified during surgery. The average follow-up was 13 months (range, 9 to 40 months). Ninety-eight percent of the patients were able to return to full activities without pain at final follow-up. The minor complication rate (transient symptoms) was 20%. Clinically significant (major) complications (continued symptoms or revisionary surgery) occurred in 10% of patients. This study indicates that lateral ankle ligamentous incompetence, combined peroneal brevis and longus tears, and low-lying peroneus muscle belly commonly coexist in patients with peroneal tendon injuries. Appropriate surgical intervention of peroneal tendon tears and their coexisting pathology yields successful and predictable results with few clinically significant complications.
