PURPOSE: The purpose of this study was to compare the clinical outcomes of A1 pulley release with ulnar superficialis slip resection (group A) and simple A1 pulley release (group B) in trigger finger with flexion contracture of the proximal interphalangeal (PIP) joint.
METHODS: From January 2016 to December 2019, the 2 surgical procedures were performed alternately every year for trigger fingers with preoperative PIP joint flexion contractures of ≥10°. Twenty-six fingers in group A and 29 fingers in group B that were followed up for >1 year were reviewed in this retrospective study. The visual analog scale (VAS) score; Disabilities of the Arm, Shoulder, and Hand (DASH) score; degree of PIP joint flexion contracture; grip strength; and pinch strength were measured after surgery and compared.
RESULTS: The differences in postoperative PIP joint flexion contracture between groups were <4° at 2 and 6 weeks, and there were no clinically relevant differences at 6 weeks and 12 months. At the final follow-up, PIP joint flexion contractures of 5° were observed in 2 fingers in each group. The difference in VAS scores between groups was less than half of a point until 3 months, and there were no clinically relevant differences at 6 weeks and 12 months. The DASH score did not show any difference between groups at the final follow-up. There were clinically relevant differences in the grip and pinch strengths between groups at 6 weeks. However, there were no clinically relevant differences at the final follow-up.
CONCLUSIONS: Proximal interphalangeal joint flexion contracture measurements and clinical scores did not differ between groups at the final follow-up. Therefore, we recommend use of a simple A1 pulley release, which is simpler than an A1 pulley release with ulnar superficialis slip resection, in cases of trigger finger with PIP joint flexion contracture.
TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
