Abstract

Aim: Carpal tunnel release generally improves symptoms across electrodiagnostic severity groups, but whether preoperative electromyography (EMG) severity is associated with residual postoperative symptoms remains uncertain. This study evaluated this association after mini-open carpal tunnel release. Methods: This single-center retrospective cohort included 112 adults with moderate (n=51) or severe (n=61) EMG-reported median nerve involvement who underwent mini-open release between January 2022 and January 2024 and had at least 12 months of follow-up. The presence or absence of residual numbness/paresthesia, residual pain, nocturnal symptoms, reoperation, and complications was assessed at final follow-up. Groups were compared using Fisher’s exact test; exploratory univariable logistic regression was limited to numbness/paresthesia and pain. A post hoc Bonferroni sensitivity analysis for five outcomes used p<0.01. Results: Median age was 50.5 years (IQR, 42.8–59.0), 85.7% were female, and median follow-up was 23.0 months (IQR, 15.8–36.3). Residual numbness/paresthesia was nominally more frequent in the severe group (24.6% vs. 9.8%; p=0.049) but did not meet the Bonferroni-adjusted threshold. The exploratory univariable estimate was OR 3.00 (95% CI, 1.01–8.94). Given the wide confidence interval and multiplicity adjustment, this finding was considered potentially attributable to chance and hypothesis-generating. Conclusions: Preoperative EMG severity showed no robust association with postoperative outcomes. The nominal finding for numbness/paresthesia did not remain significant after multiplicity correction and requires confirmation in larger prospective studies. EMG findings should be interpreted as an adjunct to clinical evaluation.

Özet

Amaç: Karpal tünel gevşetme, elektrodiyagnostik şiddet grupları genelinde semptomları iyileştirmektedir; ancak preoperatif elektromiyografi (EMG) şiddetinin rezidüel postoperatif semptomlarla ilişkisi belirsizdir. Bu çalışma, mini-açık karpal tünel gevşetme sonrasında bu ilişkiyi değerlendirdi. Yöntemler: Bu tek merkezli retrospektif kohorta, Ocak 2022–Ocak 2024 arasında mini-açık gevşetme uygulanan, EMG’de orta (n=51) veya ağır (n=61) medyan sinir tutulumu bulunan ve en az 12 ay izlenen 112 erişkin dahil edildi. Son kontrolde rezidüel uyuşma/parestezi, rezidüel ağrı, nokturnal semptomlar, yeniden operasyon ve komplikasyonların varlığı veya yokluğu değerlendirildi. Gruplar Fisher kesin testiyle karşılaştırıldı; keşifsel tek değişkenli lojistik regresyon uyuşma/parestezi ve ağrı ile sınırlandırıldı. Beş sonuç için post hoc Bonferroni duyarlılık analizinde p<0,01 eşiği kullanıldı. Bulgular: Medyan yaş 50,5 yıl (IQR, 42,8–59,0), kadın oranı %85,7 ve medyan takip 23,0 ay (IQR, 15,8–36,3) idi. Rezidüel uyuşma/parestezi ağır grupta nominal olarak daha sıktı (%24,6’ya karşı %9,8; p=0,049), ancak Bonferroni ile düzeltilmiş eşiği karşılamadı. Keşifsel tek değişkenli tahmin OR 3,00 (%95 GA, 1,01–8,94) idi. Geniş güven aralığı ve çoklu karşılaştırma düzeltmesi nedeniyle bu bulgu, rastlantıya bağlı olabilecek hipotez oluşturucu bir sonuç olarak değerlendirildi. Sonuç: Preoperatif EMG şiddeti postoperatif sonuçlarla sağlam bir ilişki göstermedi. Uyuşma/paresteziye ilişkin nominal bulgu çoklu karşılaştırma düzeltmesinden sonra anlamlılığını korumadı ve daha büyük prospektif çalışmalarda doğrulanmalıdır. EMG bulguları klinik değerlendirmeye yardımcı bir unsur olarak yorumlanmalıdır.
