축구 선수에서 자기공명영상를 통한 슬괵근 손상에 대한 평가

Abstract

Purpose: The most frequent form of trauma incurred in soccer games is muscle injury, with the hamstring being the most frequently injured muscle. However, no recent specific research has been conducted on hamstring injuries in domestic soccer players. This study aimed to evaluate the site and extent of injury, injury mechanism, player position, and the reinjury incidence in the hamstring by using magnetic resonance imaging. Materials and Methods: A retrospective study was performed with 18 soccer players with hamstring injuries diagnosed by using magnetic resonance imaging between January 2011 and June 2015. The players participated in the classic K-league, challenger’s league, middle school, high school, and university soccer teams. The injury sites included the biceps femoris, semitendinous, and complex muscles (combination of the biceps femoris and semitendinous). The extent of the injury was measured on the axial plane by calculating the percentage of the largest injured area from the whole muscle area. The correlations of the extent of injury and injury mechanism, player position, and reinjury incidence were analyzed by using the SPSS v21.0 (IBM, Armonk, NY, USA). Statistical significance was defined if the p value was <0.05. Results: The number of injuries at each site was 6. Of the players injured, 3 were offenders, 9 were midfielders, 6 were defenders. The injury occurred during changing directions in 13 players and during sprinting in 5. The injury sites were the tendinous, musculotendinous, and muscular portions in 4, 5, and 9 players, respectively. The mean extents of the hamstring injuries were 77.61%, 59.59%, and 35.41% in the offenders, midfielders, and defenders, respectively. The offenders had the largest injuries (p = 0.011). The mean extents of the hamstring injuries were 76.51%, 31.21%, and 55.88% for the biceps femoris, semitendinous, and complex muscles, respectively. The extent of injury was worst in the biceps femoris (p = 0.005). Changing directions caused the largest injury (p = 0.012). No statistically significant correlation was found between the extent of injury and reinjury incidence. Conclusion: Hamstring injury was worst in the offenders, but the injured muscles were the same. The injuries occurred due to sudden directional change. Therefore, to prevent hamstring injury, offenders must be cautious when making a sudden directional change.
