Abstract
PURPOSE: To compare the short-term efficacy of the Artelon trapeziometacarpal (TMC) implant with that of total trapeziectomy and abductor pollicis longus (APL) tendon suspension interposition arthroplasty in TMC osteoarthritis. METHODS: A single-center matched cohort study was designed. The Artelon cohort comprised 13 consecutive patients (10 women, 3 men; mean age, 54 years) operated on with Artelon implant arthroplasty. The APL cohort comprised 40 patients (33 women, 7 men; mean age, 58 years) randomly selected among 88 consecutive age-matched patients operated on with APL arthroplasty during the same period. The mean follow-up time was 13 (SD, 4) months for the Artelon group and 12 (SD, 3) months for the APL group. All patients... (More)

The APL cohort comprised 40 patients (33 women, 7 men; mean age, 58 years) randomly selected among 88 consecutive age-matched patients operated on with APL arthroplasty during the same period. The mean follow-up time was 13 (SD, 4) months for the Artelon group and 12 (SD, 3) months for the APL group. All patients completed the short-form Disabilities of the Arm, Shoulder, and Hand (QuickDASH) survey and a scale measuring thumb pain and related activity limitation, both scored 0 (best) to 100 (worst). Patient satisfaction was recorded. Physical examination was performed by a blinded therapist. RESULTS: The median QuickDASH score was 25 for the Artelon group and 20 for the APL group; the median pain scores were 38 and 28, respectively; the differences were not statistically significant. In the Artelon group, 8 patients were satisfied, compared with 32 in the APL group; the adjusted odds ratio of not being satisfied following Artelon implant compared to APL arthroplasty was 4. The median grip strength as a percentage of the contralateral hand was 82% in the Artelon group and 95% in the APL group; the median pinch strength was 61% and 86%, respectively. No statistically significant differences were found in thumb palmar or radial abduction. Two Artelon patients had revision to APL arthroplasty. CONCLUSIONS: The short-term outcomes of the Artelon TMC implant were not superior to those of tendon suspension interposition arthroplasty, a factor to be considered when comparing treatment cost effectiveness. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III. (Less)
