Arthrodesis of the talonavicular joint using angle-stable mini-plates: a prospective study.

摘要

The talonavicular joint is a central connection of the human foot. Symptomatic talonavicular arthritis can be adequately addressed by isolated talonavicular fusion. However, non-union remains a relevant clinical challenge to the orthopaedic surgeon. The aim of this study was to analyse the clinicoradiological outcome of talonavicular fusion using angle-stable mini-plates.We performed 30 talonavicular fusions in 30 patients (12 male, 18 female) with a mean age of 58.8?years (range, 22-74) between 2005 and 2007. Osseous joint fusion was achieved using mono- and multidirectional angle-stable mini-plates. The patients followed a standardised immobilisation and weight bearing protocol. The mean postoperative follow up was 15.8?months (6.1-23.8).The American Orthopedic Foot and Ankle Society AOFAS score increased significantly from 31.7 (19-42) to 82.3 points (55-97) (p?
