Purpose
We evaluated the clinical outcomes of a series of patients with hyperextension deformity
of the proximal interphalangeal joint treated with volar capsulodesis.
Methods
This retrospective study included 16 patients with symptomatic locking of the proximal
interphalangeal joint who underwent volar capsulodesis and were followed for at least
2 years. We excluded patients with severe, degenerative changes on plain radiographs.
Clinical evaluation included the Quick Disabilities of the Arm, Shoulder, and Hand
questionnaire; Catalano’s scale for proximal interphalangeal joint hyperextension
deformity correction; a visual analog scale for pain; range of motion; and grip strength.
Hyperextension recurrence and residual flexion contracture were also recorded.
Results
There were 2 women and 14 men, with a mean age of 36 years (range, 22–60 years). The
mean preoperative pain scores according to the visual analog scale were 3.6 (range,1–8)
and 0.5 (range, 0–3) at the final follow-up. No patient had a recurrence of the hyperextension
deformity. The average Quick Disabilities of the Arm, Shoulder, and Hand score was
5, and the mean grip strength was 87% of the contralateral side. Five patients were
rated as having excellent results, 9 patients as having good results, and 2 patients
as having fair results. Residual flexion contracture was less than 10° in 13 patients
and more than 10° in 3 cases. All patients returned to unrestricted activities.
Conclusion
Volar capsulodesis with early active motion demonstrated favorable results and could
be considered as a surgical option for the treatment of chronic hyperextension deformity
of the proximal interphalangeal joint.
Type of study/level of evidence
Therapeutic IV.
