Objective To compare the effects of repairing and not lateral ulnar collateral ligament (LUCL) when surgically treating elbow varus posteromedial rotatory instability (PMRI). Methods In this retrospective study spanning June 2014 to February 2019, 24 patients with PMRI who were treated assigned group RL (Repair LUCL) or NL (Non‐repair depending on whether LUCL was repaired. Hospitalization time, operation intraoperative blood loss, related complications reviewed. The range motion (ROM), visual analog scale (VAS), Mayo performance score (MEPS), disabilities arm, shoulder, hand (DASH) used for functional assessment. Results Among PMRI, 15 nine NL. mean loss (184.66 ± 20.3 vs 207.33 19.447, P < 0.001), time (98.88 12.693 min 184.66 min, 0.001) significantly lower in compared There no significant differences between two groups until surgery follow‐up (6.66 1.838 6.11 1.900 days, 25.53 2.099 26.11 2.891 months, = 0.577, 0.486). All achieved bone union. flexion‐extension ROM (122.00° 3.162° 121.11° 3.333° at 12 0.520) pronation‐supination (154.53° 3.335° 155.55° 4.639° 0.537). Both similar results MEPS (90.53 2.695 89.77 3.865, 0.578) DASH (9.77 1.897 9.99 1.550, 0.772) final follow‐up. And revealed excellent (87% RL, 89% NL).The VAS scores decreased (from 6.13 0.990 1.93 0.593) 5.77 1.481 1.88 0.781), preoperative observed ( 0.487, 0.876). Complications one patient occurred cubital tunnel syndrome 3 months after operation, underwent nerve simple neurolysis symptoms relieved weeks. Conclusion For satisfactory outcomes can be yielded non‐repair as long stable joint is performed during operation.
