OBJECTIVE
The aim of our study was to assess a group of patients with calf muscle tears and evaluate the integrity of the connective tissue boundaries and interfaces. Further, we propose a novel MRI grading system based on integrity of the connective tissue and assess any correlation between the grading score and time to return to play. We have also reviewed the anatomy of the calf muscles.
MATERIALS AND METHODS
We retrospectively evaluated 100 consecutive patients with clinical suspicion and MRI confirmation of calf muscle injury. We evaluated each calf muscle tear with MRI for the particular muscle injured, location of injury within the muscle and integrity of the connective tissue structure at the interface. The muscle tears were graded 0-3 depending on the degree of muscle and connective tissue injury. The time to return to play for each patient and each injury was found from the injury records and respective sports doctors.
RESULTS
In 100 patients, 114 injuries were detected. Connective tissue involvement was observed in 63 out of 100 patients and failure (grade 3 injury) in 18. Mean time to return to play with grade 0 injuries was 8 days, grade 1 tears was 17 days, grade 2 tears was 25 days and grade 3 tears was 48 days (p<0.001).
CONCLUSION
The integrity of the connective tissue can be used to estimate and guide the time to return to play in calf muscle tears.
目的
我们研究的目的是评估一组小腿肌肉撕裂患者，并评估其结缔组织边界和界面的完整性。此外，我们提出了一种基于结缔组织完整性的新的 MRI 分级系统，并评估分级评分与重返赛场时间之间的任何相关性。我们还回顾了小腿肌肉的解剖结构。
材料和方法
我们回顾性评估了 100 例连续的小腿肌肉损伤有临床怀疑和 MRI 证实的患者。我们用 MRI 评估了每例小腿肌肉撕裂，评估了特定受伤肌肉、肌肉内损伤部位以及界面处结缔组织结构的完整性。根据肌肉和结缔组织损伤的程度，肌肉撕裂分为 0-3 级。从损伤记录和各自的运动医生处找到了每位患者和每个损伤的重返赛场时间。
结果
在 100 例患者中，发现了 114 处损伤。在 100 例患者中有 63 例患者存在结缔组织受累，18 例患者存在断裂（3 级损伤）。0 级损伤的重返赛场时间为 8 天，1 级撕裂为 17 天，2 级撕裂为 25 天，3 级撕裂为 48 天（p<0.001）。
结论
结缔组织的完整性可用于估计和指导小腿肌肉撕裂的重返赛场时间。
