Abstract:Objective To evaluate the surgical efficacy of coalition resection with extensor digitorum brevis interposition in symptomatic patients with calcaneonavicular coalition.Methods Retrospective study. A total of 9 patients (10 feet) with symptomatic calcaneonavicular coalition were included in the Department of Foot and Ankle Surgery of Beijing Tongren Hospital from February 2016 to March 2018, who underwent calcaneonavicular coalition resection with extensor digitorum brevis interposition, which consisted of 6 males and 3 females with a mean age of 30.3 (range, 11-63) years. Two feet were osseous coalition and the others (8 feet) were fibrous coalition. Observation of surgical effect included: wound infection, pain, coalition recurrence, adjacent joint degeneration, and foot deformities. The visual analogue scale (VAS) and American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score were evaluated preoperatively and postoperatively.Results The 9 patients were followed up for 17-42 months, the mean followed-up time was 29.1 months. All patients showed remission of symptoms, no wound infection, coalition recurrence, adjacent joint degeneration or abnormal posterior foot strength line occured. Postoperative VAS (1.50±0.97) at the last follow-up was obviously lower than preoperative VAS (4.30±1.49), with a difference of 3 (2,3), indicating a statistically significant difference (Z=2.859, P<0.01). Postoperative AOFAS score at the last follow-up (90.40±7.04) was obviously higher than preoperative AOFAS score (77.30±7.66), with a difference of (13.10±5.70), indicating a statistically significant difference (t=7.262, P<0.01). All patients were satisfied with the treatment results.Conclusions For symptomatic calcaneonavicular coalition patients, surgical treatment is feasible when conservative treatment fails. After calcaneonavicular coalition resection, extensor digitorum brevis interposition can prevent coalition recurrence and acquire positive surgical efficacy.
