Recurrence of Equinus Foot in Cerebral Palsy following Its Correction—A Meta-Analysis

Abstract

Background: Recurrence in cerebral palsy (CP) patients who have undergone operative or non-operative correction varies greatly from one study to another. Therefore, we conducted this meta-analysis to determine the pooled rate of equinus recurrence following its correction either surgically or non-surgically. Methods: Nine electronic databases were searched from inception to 6 May 2021, and the search was updated on 13 August 2021. We included all studies that reported the recurrence rate of equinus following its correction among CP patients. The primary outcome was recurrence, where data were reported as a pooled event (PE) rate and its corresponding 95% confidence interval (CI). We used the Cochrane’s risk of bias (RoB-II) tool and ROBINS-I tool to assess the quality of included randomized and non-randomized trials, respectively. We conducted subgroup analyses to identify the sources of heterogeneity. Results: The overall rate of recurrence was 0.15 (95% CI: 0.05–0.18; I2 = 88%; p < 0.01). Subgroup analyses indicated that the laterality of CP, study design, and intervention type were significant contributors to heterogeneity. The recurrence rate of equinus differed among interventions; it was highest in the multilevel surgery group (PE = 0.27; 95% CI: 0.19–0.38) and lowest in the Ilizarov procedure group (PE = 0.10; 95% CI: 0.04–0.24). Twelve studies had a low risk of bias, eight had a moderate risk, and nine had a serious risk of bias. Conclusion: The recurrence of equinus following its correction, either surgically or non-surgically, in CP patients is notably high. However, due to the poor quality of available evidence, our findings should be interpreted with caution. Future studies are still warranted to determine the actual risk of equinus recurrence in CP.

Perfil Epidemiológico De Pacientes Com Paralisia Cerebral Assistidos Pelo Serviço De Ortopedia Da Oficina Ortopédica Fixa/Ceriii/Ueafto/CCBS/Uepa

“…A Paralisia Cerebral (PC) corresponde a uma lesão cerebral que provoca distúrbios neuromotores não progressivos originados durante os estágios iniciais do desenvolvimento, caracterizando-se por alterações neurológicas permanentes, principalmente de cunho motor e cognitivo (Bax, 1964;Cantero et al, 2021;Horsch et al, 2022). Dos 49 pacientes incluídos neste estudo, 30 eram homens (61,22%) e 19 mulheres (38,77%).…”
