Abstract |
Background |
Trapeziectomy with ligament reconstruction and tendon interposition (LRTI) is performed for treating thumb carpometacarpal osteoarthritis. However, patients occasionally experience delayed postoperative recovery. Although several prognostic factors associated with long-term outcomes have been identified, the factors associated with delayed recovery after trapeziectomy with LRTI have not been identified.
Hypothesis |
When we define major disability in the early postoperative period at 3 months after LRTI surgery as delayed recovery, some preoperative factors can influence with delayed recovery. Moreover, delayed recovery can influence the long-term therapeutic outcome.
Patients and methods |
Thirty thumbs that underwent trapeziectomy with LRTI (mean follow-up period, 29.3 months) were retrospectively analyzed. Major disability was defined by both DASH and Hand20 scores≥35 after surgery, and patients were divided into groups 1 (major disability; n=9) and 2 (no major disability; n=21) according to the scores at 3 months after surgery. Preoperative data, including age, sex, preoperative symptom duration, dominant hand surgery, concurrent surgery with LRTI, previous orthopedic surgery, employment, stage of osteoarthritis, thickness of the trapezium, metacarpophalangeal hyperextension deformity, DASH score, Hand20 score, visual analogue scale (VAS) scores for pain, grip strength, pinch strength, and range of motion of the thumb were compared between groups to identify the factors indicating a poor prognosis at 3 months after surgery. We also compared the clinical outcomes at the 12-month and final follow-up.
Results |
Dominant hand surgery, previous orthopedic surgery, and preoperative poor DASH score were significantly more frequent in group 1, while the other factors did not show significant intergroup differences. Moreover, group 1 showed significantly poorer DASH score, grip and pinch strength, and active flexion of the thumb metacarpal joint at both the 12-month and final follow-up. This group also showed significantly poorer Hand20 and VAS scores at the final follow-up.
Discussion |
Dominant hand surgery, previous orthopedic surgery, and preoperative poor DASH score were associated with poor recovery at 3 months after trapeziectomy with LRTI. Moreover, major disability at 3 months after surgery influenced poor clinical outcomes at the 12-month and final follow-ups. These data could be useful for counseling patients regarding the expected recovery duration and outcomes after LRTI surgery.
Level of evidence |
IV; retrospective therapeutic study.
