Modified double-row biceps tenodesis (MDBT) has been proved to be effective in treating slap injuries, but the impact of closing the rotator cuff gap remained postoperatively (the Pulley ring repair) on the long-term shoulder function and stability has not been conclusively investigated.
A retrospective study was conducted on 157 patients with isolated unilateral type II SLAP lesions treated with MDBT from January 2019 to January 2023. 77 patients were without the Pulley ring repair (group A) and the remaining 80 patients were with the Pulley ring repair (group B). -test, Anova, and chi-square analyses were used to compare the two groups for any statistical differences in the 37 variables. Lasso regression was used to screen and analyze the variables, assess risk, and construct a predictive assessment model.
There were significant differences between the two groups at 1 year in ASES and UCLA score ( < 0.01). Risk factors screened by LASSO regression were five including Grouping information, Mean T value of bone mineral density, and 3 Months post operation's UCLA score. These statistically significant variables and their coefficients were used to build a generalized linear equation and selected to build the final model including Grouping information (OR:1.61E + 01;95% CI:5.8854-52.5200), Mean T value of bone mineral density (OR:6.95E + 00;95% CI:2.4695-25.6797) and 3 Months post operation UCLA score (OR:1.77E + 00;95% CI:1.4810-2.2539).
Compared with the traditional MDBT, the modified MDBT is more effective in improving the long-term function of the glenohumeral joint and better restoring the biological state of the glenohumeral joint.
改良双排二头肌肌腱固定术（MDBT）已被证明在治疗SLAP损伤方面有效，但术后闭合肩袖间隙（滑轮环修复）对长期肩部功能和稳定性的影响尚未得到最终研究。
对2019年1月至2023年1月期间接受MDBT治疗的157例孤立性单侧II型SLAP损伤患者进行回顾性研究。77例患者未进行滑轮环修复（A组），其余80例患者进行了滑轮环修复（B组）。采用t检验、方差分析和卡方分析比较两组在37个变量上的统计学差异。采用套索回归筛选和分析变量、评估风险并构建预测评估模型。
两组在术后1年的ASES和UCLA评分上存在显著差异（P<0.01）。套索回归筛选出的危险因素有5个，包括分组信息、骨密度平均T值和术后3个月的UCLA评分。这些具有统计学意义的变量及其系数被用于构建广义线性方程，并选择构建最终模型，包括分组信息（OR：1.61E+01；95%CI：5.8854 - 52.5200）、骨密度平均T值（OR：6.95E+00；95%CI：2.4695 - 25.6797）和术后3个月UCLA评分（OR：1.77E+00；95%CI：1.4810 - 2.2539）。
与传统的MDBT相比，改良的MDBT在改善盂肱关节长期功能和更好地恢复盂肱关节生物学状态方面更有效。
