ABSTRACT

BACKGROUND: Screw head prominence in the heel following fixation for calcaneal osteotomy or subtalar arthrodesis has resulted in high rates of symptomatic hardware and screw removal. A cost analysis was performed to determine the financial implications of screw removal. Furthermore, we compared the rate of nonunion following fixation. METHODS: Current Procedural Terminology codes were used to identify all patients who had a subtalar arthrodesis or calcaneal osteotomy (with screw fixation) performed between 2010 and 2016. The cohort was divided into 2 groups: 7.0-mm headless screw or 6.7-mm headed screw. The primary outcome measure was the rate of symptomatic screw removal. Secondary outcomes included the rate of nonunion. The expense associated with symptomatic hardware removal was determined by cost analysis. RESULTS: Seventy-six patients underwent headless screw fixation, and 2 patients (2.6%) required screw removal. Fifty-four patients underwent headed screw fixation and 12 patients (22.2%) required screw removal. Symptomatic hardware removal was performed more frequently in the headed screw group (P < .001). There was no difference in the rate of nonunion after subtalar arthrodesis between the 2 groups (P = .363). The calcaneal osteotomy united in 100% of patients. There was a $51 755 cost savings per 100 cases using headless screw fixation. CONCLUSION: The rate of symptomatic screw removal was lower with headless screw fixation. The calcaneal osteotomy healed in 100% of patients, and there was no difference in the rate of subtalar nonunion between the 2 groups. Cost analysis demonstrated a significant benefit when the expense of hardware removal was considered. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

ABSTRACT

Posterior ankle pain is a common complaint, and the potential causative pathologic processes are diverse. The constellation of these numerous etiologies has been collectively referred to as posterior ankle impingement syndrome. The pain associated with posterior ankle impingement is caused by bony or soft tissue impingement of the posterior ankle while in terminal plantar flexion. This condition is most frequently encountered in athletes who participate in sports that involve forceful, or repetitive, ankle plantar flexion. This article discusses the associated pathology, diagnosis, conservative treatment, and surgical techniques associated with flexor hallucis longus and posterior ankle impingement syndrome.

ABSTRACT

Between January 1, 2011, and January 1, 2017, an orthopaedic foot and ankle surgeon performed tibiotalar arthrodesis on 221 patients. Thirty-two were included in this study. Inclusion criteria included patients with at least one risk factor for nonunion and/or malunion, isolated anterior ankle arthrodesis with plate fixation, patients older than 18, and a minimum of 1-year follow-up. Risk factors were avascular necrosis of the talus, severe segmental bone defect, smoking, inflammatory arthropathy, coronal deformity greater than 15°, diabetes mellitus, septic nonunion, failed ankle arthrodesis, and body mass index greater than 35. Functional outcome questionnaires (Ankle Osteoarthritis Score [AOS] and Foot Function Index [FFI]) were collected at the latest visit or by phone. Twenty-six (26/32, 81.2%) patients included in the study had computed tomography images available for review at an average of 3.2 months after surgery. The rate of successful arthrodesis was 93.8% (30/32) at an average of 78 days. Overall, 14 patients (14/32, 43.8%) developed a postoperative complication, including 1 patient that had a delayed nonunion and 2 patients that proceeded to nonunion. Twenty-three patients (23/32, 71.9%) completed the functional outcome questionnaires at an average of 26.8 months. Mean AOS and FFI scores improved significantly postoperatively (P < .001). Sagittal tibiotalar and coronal tibiotalar alignment improved significantly in patients with severe preoperative deformity (P < .001). Tibiotalar arthrodesis with anterior plate fixation in a high-risk cohort results in high union rates and significantly improved functional outcomes. Levels of Evidence: Therapeutic, Level IV: Prospective, comparative trial.
