Uji Korelasi Kekuatan Genggaman Tangan Pasca Fraktur Distal Radius yang Ditatalaksana Fiksasi Interna dengan Parameter Radiologi di RSUP Haji Adam Malik Medan

Abstract

OBJECTIVE The purpose of this study to determine the correlation between hand grip strengh distal radius fracture treated with internal fxation and radiological parameters MATERIAL AND METHODS This is a correlation analytic study with cross sectional approach. The study was conducted at the Orthopaedic outpatient clinic in Haji Adam Malik General Hospital. The data were taken from patient’s medical record who had distal radius fracture and undergo internal fixation. The sampling were taken by consecutive method. Hand grip strength ratio and radiological parameters data were processed in systematic method and were analysed by a computer-based program. The significance level were 5% (0.05). Correlation test were done depend on the result of normality test. We were using Pearson Correlation test if the distribution data were normal and Spearman Correlation test if the distribution data were not normal. RESULT 25 subjects were identified with 9 female patients (36%) and 16 male patients (64%). The youngest age was 18 years-old, the oldest age was 63 years-old within the mean age was 34.72± 13,52 years. Correlation Spearman test was performed and showed there’s correlation between hand grip strength ratio and ulnar variance (r =0.39), hand grip strength ratio and palmar tilt (r = -0,62) CONCLUSION There is a moderate correlation between hand grip strength ratio with palmar tilt and also weak correlation with ulnar variance.

OBJEKTIF Penelitian ini bertujuan untuk mengetahui korelasi kekuatan genggaman tangan pasca fraktur distal radius yang ditatalaksana fiksasi interna terhadap parameter radiologi. MATERIAL DAN METODE Jenis penelitian ini adalah studi analitik korelatif dengan pendekatan cross sectional. Penelitian dilakukan di poliklinik Orthopaedi RSUP H Adam Malik Medan. Data diambil dari rekam medis pasien fraktur distal radius yang menjalani fikasi interna dan kontrol ke poliklinik. Metode pengambilan sampel dilakukan secara konsekutif. Data rasio kekuatan genggaman tangan dan parameter radiologi diolah secara sistematis dan dianalisis melalui program analisis statistic berbasis komputer dengan uji korelasi Pearson bila distribusi data normal dan uji korelasi Spearman bila distribusi tidak normal HASIL Sebanyak 25 subjek penelitian dengan karakteristtik 9 pasien berjenis kelamin perempuan (36%), 16 pasien berjenis kelamin laki-laki (64%). Dengan rerata usia dan standard deviasi sebesar 34,72 ± 13,52 tahun. Uji Korelasi Spearman menunjukkan terdapat signifikan korelasi adalah antara rasio kekuatan genggaman tangan dengan ulnar variance (r = 0,39) dan kekuatan genggaman tangan dengan palmar tilt (r = -0,62). KESIMPULAN Dari penelitian didapatkan terdapat korelasi antara rasio kekuatan genggaman tangan terhadap palmar tilt dan ulna variance
