Quantitative review of operative management of hallux rigidus

Abstract

Introduction: Surgical techniques for the management of hallux rigidus include cheilectomy, Keller resection arthroplasty, arthrodesis, Silastic implantation, phalangeal or metatarsal osteotomy, capsular arthroplasty, partial or total joint replacement, interposition arthroplasty. However, the optimal management is controversial.

Sources of data: We performed a comprehensive search of CINAHL, Embase, Medline and the Cochrane Central Registry of Controlled Trials, from inception of the database to 2 November 2010. Sixty-nine articles published in peer reviewed journals were included in this comprehensive review.

Areas of agreement: Cheilectomy and first metatarsal or phalangeal corrective osteotomy may provide better outcome for patients with early and intermediate hallux rigidus (Stages I-II), while arthrodesis or arthroplasty are indicated to manage more severe conditions. The Coleman Methodology Score showed great heterogeneity in terms of study design, patient characteristics, management methods and outcome assessment and generally low methodological quality.

Areas of controversy: Definitive conclusions on the use of these techniques for routine management of patients with hallux rigidus are not possible. Given the limitations of the published literature, especially the extensive clinical heterogeneity, it is not possible to compare outcomes of patients undergoing different surgical procedures and determine clear guidelines.

Growing points: To assess whether benefits from surgery, validated and standardized measures should be used to compare the outcomes of patients undergoing standard surgical procedures.

Research: There is a need to perform appropriately powered randomized clinical trials of using standard diagnostic assessment, common and validated scoring system comparing reported outcomes and duration of follow-up >2 years.
