Abstract

in English, Chinese

Objective:

To investigate the short-term effectiveness of talonavicular joint arthrodesis and calcaneus osteotomy in the treatment of Müller-Weiss disease.

Methods:

Between June 2015 and February 2017, 14 patients diagnosed Müller-Weiss disease, who were ineffective on conservative treatment, were treated with talonavicular joint arthrodesis and calcaneus osteotomy. There are 3 males and 11 females, with an average age of 46.2 years (range, 35-56 years). According to the Maceira grading criteria, 5 patients were rated as stage Ⅲ and 9 patients as stage Ⅳ. The disease duration ranged from 4 to 12 years (mean, 7 years). Preoperative X-ray films showed that all patients were not accompanied with adjacent joint arthritis. The hindfoot axis on Saltzman view was (9.8±2.8)°, calcaneal pitch angle (CPA) on lateral position was (14.7±5.1)°, Meary angle on lateral position was (4.8±2.8)°, and talar 1 meta-tarsal angle (T1MA) on anteroposterior position was (25.0±7.3)°. Preoperative visual analogue scale (VAS) score was 5.9±1.5, American Orthopedic Foot Ankle Society (AOFAS) ankle-hindfoot score was 58.8±17.6.

Results:

All patients were followed up 14-27 months (mean, 22.3 months). Medial numbness and incision infection occurred in 2, 2 cases, respectively. The other patients had no obvious discomfort. At last follow-up, VAS score was 1.6±1.3 and AOFAS score was 90.6±2.7, showing significant differences when compared with preoperative ones ( t=8.18, P=0.00; t=-6.95, P=0.00). X-ray films showed that the talonavicular joint and calcaneus osteotomy achieved bony healing. The hindfoot axis on Saltzman view was (-2.5±2.7)°, CPA on lateral position was (25.0±5.2) °, Meary angle on lateral position was (2.6±2.1)°, T1MA on anteroposterior position was (8.1±3.8)°. There was no significant difference in Meary Angle between pre- and post-operation ( t=1.53, P=0.15). And there were significant differences in the hindfoot axis, CPA, and T1MA between pre- and post-operation ( t=11.93, P=0.00; t=-8.89, P=0.00; t=8.05, P=0.00).

Conclusion:

For Müller-Weiss disease patients without adjacent joint arthritis, who are ineffective on conservative treatment, the satisfied short-term effectiveness can be obtained when treated by talonavicular joint arthrodesis and calcaneus osteotomy.
