Objective: To explore the curative effect of limited soft tissue release combined with different external fixation methods in the treatment of spastic cerebral palsy equinovarus foot. Methods: A retrospective analysis of the medical record data included in the criteria from September 1, 2019 to December 31, 2020, a total of 41 cases (58 feet) met the inclusion criteria. The general information of the patient and AOFAS scores of the ankle-hindfoot before and after treatment, and Ashworth quantification of the tibialis posterior muscle, tibialis anterior muscle, and calf triceps muscle group The scores were recorded, and SPSS22.0 software was used for statistical processing. Results: 41 cases (58 feet) were followed up for at least 3 months. The ratio of male to female in 41 cases (58 feet) was 19:22, and most of the affected parts were on the left foot (31 cases, 53.45%); the age at the time of treatment was mostly 11-14 years old, accounting for 56.10%; the types of external fixation selected for treatment were combined Type and ring type external fixators are the main ones, accounting for 50.00% and 41.38% respectively. The higher frequency of surgery categories are: Achilles tendon lengthening, posterior tibial tendon lengthening (84.48%); foot osteotomy or joint fusion (74.14) %). There were statistically significant differences in ankle dorsal extensor strength, valgus muscle strength, muscle tension, ankle-hindfoot AOFAS score, ICFSG score, ASHWORTH score and curative effect grading in all cases after removal of the external fixator and at the last follow-up. (P<0.05). Conclusion: The combination of limited soft tissue loosening and external fixation can achieve satisfactory and relatively ideal results in the treatment of spastic cerebral palsy clubfoot deformity. However, it is necessary to develop a personalized surgical plan and rehabilitation plan according to the degree of ankle deformity.
