Abstract:
Objective:To explore the feasibility of Ponseti method in treatment of secondary clubfoot in young children with Tethered Cord Syndrome(TCS).Methods:The clinical data of 53 young children with clubfeet treated with Ponseti method from March 2014 to March 2017 at Department of Pediatric Orthopedics, the Third Affiliated Hospital of Zhengzhou University were analyzed retrospectively. These patients were divided into TCS group and Idiopathic group according to the etiology. There were 19 patients (33 feet) in TCS group,with an mean age of 2.8 months(range:0.2 to 24.0 months), including 13 males and 6 females, 5 patients with unilateral clubfeet and 14 patients with bilateral clubfeet. There were 34 patients (45 feet) in idiopathic group, with an mean age of 3.1 months(range: 0.1 to 21.0 months), including 18 males and 16 females, 23 patients with unilateral clubfeet and 11 patients with bilateral clubfeet. All the children received casts correction according to Ponseti method, and were followed up at 3 weeks, 3 months, 6 months and every 6 months after the Achilles tendon tenotomy or the last cast correction. Complications were recorded and therapeutic effect was evaluated of these children by Dimeglio Scoring System and the International Clubfoot Study Group (ICFSG) at the last follow-up. Independent t test, Mann-Witney U test or χ 2 test were used to compare the indicators of the two groups. Results:The number of plaster fixation in TCS group was (6.1±2.0) times, and that of idiopathic group was (4.8±1.0) times( t=3.482, P<0.01).In TCS group, 22 feet treated with Achilles tendon transection and that of idiopathic group was 40 feet(χ 2=0.279, P=0.598). There were 18 cases recurrence in TCS group and 8 cases in Idiopathic group ( t=11.149, P<0.01). In TCS group, 16 cases (27 feet) completed the initial correction, the success rate was 60.6% (27/33), 3 cases (6 feet) could not correct the deformity after 9 to 10 times of plaster fixation, and then underwent soft tissue release.In idiopathic group, 34 cases (45 feet) achieved initial correction after Ponseti treatment(χ 2=6.488, P=0.011).At the last follow up, there were 5 cases (9 feet) in TCS group and 2 cases (2 feet) in idiopathic group underwent soft tissue release(χ 2=6.110, P=0.013). The classification grade of ICFSG score of the two groups without soft tissue release were (2.1±0.6) and (1.8±0.7), the difference was not statistically significant ( t=1.765, P=0.082). All the children had no skin ulceration, bedsores, skin allergy and other complications. Conclusion:Ponseti method is effective in the treatment of clubfoot secondary to TCS, and the functional recovery is similar to that of children with idiopathic clubfoot.
