The clinical effect of the long head of biceps tendon insertion reconstruction combined with pulley repair in the treatment of pulley system injuries / 中华骨科杂志

ABSTRACT

Objective:To investigate the clinical effect of long head of biceps tendon (LHBT) insertion reconstruction combined with pulley repair for pulley system injuries.Methods:A total of 46 patients (combined treatment group) with pulley system injury treated with LHBT insertion reconstruction combined with pulley repair in the Sports Medicine Department, Affiliated Xinhua Hospital of Dalian University from January to December 2020 were retrospectively analyzed, including 16 males and 30 females, aged 51.3±5.7 years (range, 45-72 years). 46 patients who underwent simple LHBT insertion reconstruction during the same period were selected as the control group (simple reconstruction group), including 14 males and 32 females, aged 50.6±6.7 years (range, 46-70 years). Visual analogue scale (VAS), Constant-Murley score, American Shoulder and Elbow Surgeon (ASES) score and long head of biceps tendon (LHB) score were compared preoperatively and at 1, 3, 6, 12 and 24 months postoperatively.Results:All patients were followed up for 26.2±1.5 months (range, 24-27 months). The VAS scores of the combined treatment group at 1, 3, and 6 months postoperatively were 3.4±1.3, 2.0±1.1, and 1.7±0.5, respectively, which were significantly lower than those of the simple reconstruction group 5.8±1.3, 3.5±1.1, and 2.6±0.5 ( P<0.05), while there was no significant difference between the two groups at 12 and 24 months postoperatively ( P>0.05). The Constant-Murley scores of the combined treatment group at 1, 3, and 6 months postoperatively were 31.3±4.7, 72.8±4.6, and 89.1±5.4, respectively, which were statistically greater than those of the simple reconstruction group (21.5±6.8, 52.8±5.2, and 80.1±6.2), and the differences were statistically significant ( P<0.05), while there was no statistically significant difference between the two groups at 12 and 24 months postoperatively ( P>0.05). The ASES scores of the combined treatment group at 1 and 3 months postoperatively were 56.2±6.9 and 82.7±8.2, which were statistically greater than those in the simple reconstruction group (40.2±5.6 and 62.9±8.0), while there was no statistically significant difference between the two groups at 6, 12, and 24 months postoperatively ( P>0.05). The LHB scores of the combined treatment group at 6 and 12 months postoperatively were 70.1±5.4 and 86.1±4.6, which were statistically greater than those of the simple reconstruction group (60.2±4.2 and 70.2±5.8), with statistically significant differences ( P<0.05), while there was no statistically significant difference between the two groups at 24 months postoperatively ( P>0.05). Conclusion:Arthroscopic LHBT insertion reconstruction combined with pulley system repair can relieve early postoperative shoulder pain and improve early function. It is an effective method for the treatment of pulley system injury.
