Abstract
Purpose
To document the change of clinical (wrist motion and grip strength) measurements and Patient-Rated Wrist Evaluation (PRWE) scores at 9 weeks and 3, 6, and 12 months after distal radius fracture (DRF) in women 50 years and older with exclusively isolated, displaced, and low-energy DRFs treated by either closed and/or open reduction and to relate these outcomes to their radiographic results.
Methods
In this retrospective single-institution cohort study, patients’ post-DRF clinical measurements and PRWE scores were prospectively collected from December 2007 through September 2018 and stratified according to their final radiographic values of volar/dorsal tilt, ulnar variance, and radial inclination.
Results
Of the 1,319 women identified, 1,126 (85%) were treated nonsurgically, and 193 (15%) were treated operatively. At 12 months, patients averaged restoration (ratio of injured and uninjured sides’ values) of 96% pronation, 95% extension, 91% supination, 81% flexion, and 80% (77% nondominant, 85% dominant) grip strength. The mean PRWE score was 39.5 at week 9 and 14.4 at 12 months with 54% of patients scoring <10 and 13% scoring zero. The mean volar/dorsal tilt, ulnar variance, and radial inclination values in those treated nonsurgically were 1.4° dorsal, +3.9 mm, and 18.0°, respectively. Analogous values in patients treated surgically were 6° volar, +2.6 mm, and 22°, respectively. Volar tilt ≥25°, dorsal tilt >10°, ulnar variance >+7.5 mm, and radial inclination ≤13° were thresholds beyond which motion and grip strength were reduced and/or PRWE scores increased. In general, older patients experienced more residual deformity and were less likely to have undergone surgery.
Conclusions
Generally, outcomes were satisfactory for patients with radiographic results within identified thresholds for acceptable fracture reduction. Outcomes were significantly less favorable for patients with radiographic results beyond these thresholds; for these patients, early surgical intervention should be considered. Low-energy DRFs should prompt bone density investigation.
