Intrarater Reliability of Range of Motion Measurements of the Uninjured Wrist in Women After Distal Radius Fracture

Serial Range of Motion and Grip Strength Measurements, Patient-Reported Outcomes, and Radiographic Thresholds Associated With Less Satisfactory Outcomes After Low-Energy Distal Radius Fracture in Women Aged 50 Years and Older

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.

Distal Radius Fracture Rehabilitation

Distal radius fracture (DRF) is arguably the most common upper extremity fracture resulting from a fall accident. These clinical practice guidelines (CPG) were developed to guide all aspects of the management of DRF by physical therapists and other rehabilitation practitioners, such as certified hand therapists. This CPG employed a systematic review methodology to locate, appraise, and synthesize contemporary evidence while developing practice recommendations for determining the prognosis of outcomes, examination, and interventions while managing individuals with DRF. The quality of the primary studies found in the literature search was appraised using standardized tools. The strength of the available evidence for a particular practice domain (e.g., prognosis or intervention) was graded as strong, moderate, weak, or conflicting, where such gradings guided the level of obligation for each practice recommendation. Lastly, the CPG also provided the gaps in the evidence pool for the rehabilitation of DRF that future research efforts can address.

Measurement Properties of Outcome Measures Used to Assess Physical Impairments in Patients After Distal Radius Fracture: A Systematic Review

OBJECTIVES

Individuals with distal radius fractures (DRF) may experience difficulty with gripping an object, painful wrist movements, sensorimotor difficulties, and swelling around the wrist and hand. A comprehensive review of the existing evidence concerning the measurement properties of common physical impairment measures can provide a valuable resource to guide hand therapy practice while managing DRF. The primary objective was to locate and assess the quality of literature on the measurement properties for the measures of physical impairment used in individuals with DRF.

METHODS

Two reviewers searched PubMed, CINAHL, and EMBASE. A combination of DRF, measurement properties, and physical impairments were used as keywords, and articles were independently assessed using the Consensus-Based Standards for the Selection of Health Measurement Instruments critical appraisal tool. Primary studies were included if they examined at least 1 of the following: reliability, validity, responsiveness, or indices of true and meaningful changes for measures of physical impairment in the DRF sample. A total of 19 articles were included in this review. The quality of the studies ranged from 46% to 92%. This review suggests that measures such as assessment of grip strength and supination and pronation range of motion (ROM), using various goniometric devices, showed good intrarater and interrater reliability, construct validity, and responsiveness in individuals with DRF.

CONCLUSION

Acceptable reliability and responsiveness were reported in grip and wrist ROM assessments for measuring changes in wrist and hand function after DRF; however, wrist ROM assessed using traditional goniometric techniques were less reliable in individuals with DRF.

IMPACT

This study provides insight into which objective tools might be better suited for measuring outcomes related to DRF.
