Abstract

Objectives: Investigate the British Athletics Muscle Injury Classification (BAMIC) grading system as a predictor of return to play (RTP) following primary hamstring strain injury (HSI) and its agreement with the Peetron’s classification system in professional footballers.
Methods: A retrospective cohort study of 39 hamstrings strains in a professional English football club were identified. Two musculoskeletal radiologists reviewed historical MRI’s and classified them against the BAMIC and Peetron’s grading system. Classification, oedema length and cross-sectional area were compared against RTP.
Results: Pearson’s correlation coefficient demonstrated a weak but statistically significant correlation between BAMIC and RTP (r=0.32; 95%CI 0.01 to 0.58; p=0.05). Maximum length of intramuscular oedema demonstrated weak correlations with RTP (r=0.3; 95%CI -0.02 to 0.56; p=0.06). Percentage cross sectional demonstrated a weak correlation with RTP (r=0.02; 95%CI -0.3 to 0.33; p=0.91). Multiple regression demonstrated that 16% of the variance in RTP was explained by the model. Kappa for the agreement between BAMIC and Peetron’s was 0.21 (95%CI 0 to 0.42).
Conclusions: A significant association between the grade of HSI on the BAMIC system and RTP was found. Findings suggest BAMIC could provide valuable prognostic information on the RTP.
