The study aimed to determine the grade of retraction and atrophy according to the time elapsed in traumatic isolated full-thickness supraspinatus (SS) tears in young patients.
One thousand twenty-six patients, who underwent arthroscopic shoulder surgery, were retrospectively reviewed. Pre-operative magnetic resonance imaging (MRI) of 69 patients aged 18 to 40 years with isolated traumatic full-thickness SS lesions remaining after exclusion criteria were evaluated for tendon retraction and atrophy grades. SS retraction was determined from a T2-weighted oblique coronal MRI slice, and the atrophy grade was determined from the T1-weighted oblique sagittal MRI slice. The patients were divided into four groups 0-1 month, 1-3 months, 3-6 months, and 6-12 months according to the time between trauma and MRI. The relationship of tendon retraction and muscle atrophy with elapsed time was evaluated, in addition, comparisons between groups were made.
Thirty-one (45%) of the patients were female and their mean age was 30 ± 7.3 (18-40) years. The mean age of men was 30.5 ± 6.9 (18-39) years (p = 0.880). The time between rupture and MRI was moderately correlated with retraction and strongly correlated with atrophy grades (r = 0.599, 0.751, respectively). It was observed that there was a statistically significant difference between the 1st (0-1 month) and 2nd (1-3 months) groups (p = 0.003, 0.001, respectively), and between the 2nd and 3rd (3-6 months) groups (p = 0.032, 0.002, respectively), but there was no significant difference between the 3rd and 4th (6-12 months) groups (p = 0.118, 0.057, respectively). In addition, there was a moderate correlation between tendon retraction and atrophy grades (r = 0.668). Power (1- b) in post hoc analysis was calculated as 0.826.
The current study, supported by arthroscopy, showed that there is a moderate and strong positive correlation between the time elapsed after trauma and the level of retraction and degree of atrophy in traumatic full-thickness SS tears, and demonstrated the importance of early surgical intervention in young patients.
本研究旨在根据创伤性全层冈上肌腱（SS）撕裂后时间的长短，确定回缩和萎缩的程度。
回顾性分析了 1026 例接受关节镜肩关节手术的患者。对排除标准后仍存在孤立性创伤性全层 SS 病变的 69 例年龄在 18 至 40 岁的患者的术前磁共振成像（MRI）进行评估，以确定肌腱回缩和萎缩程度。SS 回缩通过 T2 加权斜冠状 MRI 切片确定，萎缩程度通过 T1 加权斜矢状 MRI 切片确定。根据创伤与 MRI 之间的时间，患者被分为 4 组：0-1 个月、1-3 个月、3-6 个月和 6-12 个月。评估了肌腱回缩和肌肉萎缩与时间的关系，并对组间进行了比较。
31 名（45%）患者为女性，平均年龄为 30±7.3（18-40）岁。男性的平均年龄为 30.5±6.9（18-39）岁（p=0.880）。破裂与 MRI 之间的时间与回缩呈中度相关，与萎缩程度呈强相关（r=0.599、0.751）。观察到第 1 组（0-1 个月）和第 2 组（1-3 个月）之间（p=0.003、0.001），第 2 组和第 3 组（3-6 个月）之间（p=0.032、0.002）存在统计学差异，但第 3 组和第 4 组（6-12 个月）之间（p=0.118、0.057）无差异。此外，肌腱回缩与萎缩程度之间存在中度相关性（r=0.668）。事后分析中的幂（1- b）计算为 0.826。
本研究通过关节镜检查支持以下观点，即在创伤性全层 SS 撕裂后，时间与回缩和萎缩程度之间存在中度和强正相关，这表明在年轻患者中早期手术干预的重要性。
