Introduction: The optimal treatment of intra-articular calcaneal fractures remains controversial.

Material and Methods: Electronic databases were searched for randomised trials comparing interventions for treating patients with calcaneal fractures. Two reviewers independently assessed trial quality, using a 12-item scale, and extracted data. Where appropriate results were pooled.

Results: Six trials met the inclusion criteria. Two reports reported on the same group of patients at differing follow-up intervals. All six included trials had methodological flaws. Another two trials are ongoing. Four trials (134 patients) compared open reduction and internal fixation (ORIF) with non-operative management. Pooled results showed no difference in residual pain (24/40 versus 24/42; OR 0.90, 95% CI 0.34 to 2.36), but a lower proportion of the operative group was unable to return to the same work (11/45 vs 23/45; OR 0.30, 95% CI 0.13 to 0.71), and was unable to wear the same shoes as before (12/52 vs 24/54; OR 0.37, 95% CI 0.17 to 0.84). One large-scale study showed that the outcomes (SF-36, visual analogue scale (VAS), Bohler’s angle) after non-operative treatment were not different to those after ORIF. ORIF gave superior results for return to work, return to normal activities and ability to wear the same shoes. The subtalar fusion rate was reduced after ORIF. Excluding patients receiving Workers’ Compensation, the outcomes were significantly better in some groups of surgically treated patients. One trial (23 patients), evaluated impulse compression therapy. At one year there was a mean difference of 1.40 pain VAS units (95% CI 0.02 to 2.82) in favour of the treated group. The impulse compression group had greater subtalar movement at three months, and patients returned to work three months earlier.

Conclusions: The relatively poor quality of existing trials means that current evidence is only tentative. It remains unclear whether the possible advantages of surgery are worth its risks.

Introduction: The use of total ankle arthroplasty for the management of end stage arthritis of the ankle is gaining in popularity. We performed a review of the literature on Total Ankle Arthroplasty to assess the methodology of studies and to detect possible variation in the reported surgical outcomes.

Material and Methods: All relevant articles in peer-reviewed journals were retrieved except those not mentioning outcomes, case reports, review of literature and letters to editors. Studies reporting on implants presently used, with at least 20 subjects followed for a mean of at least two years were included. Two authors independently scored the quality of the studies using the Coleman Methodology Score (CMS). We collected data for type of study, patient numbers, length of follow-up, complications, outcome and prosthesis survival with revision or fusion as an endpoint. Where appropriate, pooling of data was performed.

Results: Twenty-one level IV studies, published from 2003 to 2008, reporting on 2167 ankle replacements followed for a mean of 5.6 years, were included. The CMS was 65 (SD 15), with substantial agreement between the two examiners. Inflammatory arthropathy was present in 31% of ankles. The intra-operative fracture rate was 10.5%. Superficial wound healing complication rate was 6.4%, and deep infections occurred in 1.2% of ankles. Patients’ satisfaction rate was 94%. The failure rate of the primary ankle prosthesis was 11.6% (Agility: 12.2% at 4 years, STAR: 11.7% at 4.6 years and Buechel-Pappas (BP): 12.8% at 7.3 years). Pooling the data the six-year survivorship for the Agility was 0.70 (CI 95%, 0.50–0.90), whereas the 10-year survivorship for the STAR was 0.79 (CI 95%, 0.56–1.00) and for the BP 0.87 (CI 95%, 0.69–1.00).

Conclusions: Studies reporting on total ankle arthroplasty are of overall moderate quality. Survivorship analysis revealed superior results for mobile-bearing implants. Patients’ satisfaction rate was high.
