A comprehensive review of the results of needle aponeurotomy in 1,013 fingers was performed by Gary M. Pess, MD, Rebecca Pess, DPT and Rachel Pess, PsyD and published in the Journal of Hand Surgery April 2012. Minimal followup was 3 years. Metacarpophalangeal joint (MP) contractures were corrected an average of 99% and Proximal interphalangeal joint (PIP) contractures an average of 89% immediately post procedure. At final follow-up, 72% of the correction was maintained for MP joints and 31% for PIP joints. The difference between the final corrections for MP versus PIP joints was statistically significant. When a comparison was performed between patients age 55 years and older versus under 55 years, there was a statistically significant difference at both MP and PIP joints, with greater correction maintained in the older group. Gender differences were not statistically significant. Needle aponeurotomy provided successful correction to 5° or less contracture immediately post procedure in 98% (791) of MP joints and 67% (350) of PIP joints. There was recurrence of 20° or less over the original post procedure corrected level in 80% (646) of MP joints and 35% (183) of PIP joints. Complications were rare except for skin tears, which occurred in % (34) of digits. This study showed that NA is a safe procedure that can be performed in an outpatient setting. The complication rate was low, but recurrences were frequent in younger patients and for PIP contractures.
