Measuring Outcomes Over Time in Distal Radius Fractures: A Comparison of Generic, Upper Extremity-Specific and Wrist-Specific Outcome Measures

Trajectory of Recovery following ORIF for Distal Radius Fractures

Background  Distal radius fractures are commonly seen among the elderly, though studies examining their long-term outcomes are limited. Purpose  The aim of this study was to describe the 5-year trajectory of recovery of distal radius fractures treated with open reduction and internal fixation (ORIF). Methods  Patients with distal radius fractures (AO/OTA 23.A-C) treated by ORIF were prospectively studied. Patient-Rated Wrist Evaluation (PRWE) score was measured at baseline (preinjury recall) and postoperatively at 6 months, 1 year, and 5 years. Clinically relevant change in PRWE score was assessed using the minimal clinically important difference (MCID). Results  A total of 390 patients were included, of which 75% completed 5-year follow-up. Mean baseline PRWE score was 1.25 (standard deviation, SD: 2.9). At 6 months, mean PRWE score was at its highest up to 20.2 (SD: 18.4; p  < 0.01). A significant improvement in mean PRWE score was observed at 1 year down to 15.2 (SD: 17.6; p  < 0.01); 44% of patients were still one MCID outside of their baseline PRWE score at 1 year. Further significant improvement in mean PRWE score occurred at 5 years down to 9.4 (SD: 13.4; p  < 0.01); 29% of patients remained one MCID outside of their baseline PRWE score at 5 years. Conclusion  Recovery after ORIF for distal radius fractures showed significant worsening after surgery, followed by significant improvements up to 1 year and between years 1 and 5, albeit to a lesser extent. Statistically and clinically relevant wrist pain and disability persisted at 5 years. Future research should examine different treatment modalities and include a nonoperative treatment arm for comparison. Level of Evidence  Prognostic level II.

Effectiveness of asfotase alfa for treatment of adults with hypophosphatasia: results from a global registry

BACKGROUND

Hypophosphatasia (HPP) is a rare inherited disease caused by deficient activity of tissue-nonspecific alkaline phosphatase. Many adults with HPP have a high burden of disease, experiencing chronic pain, fatigue, limited mobility, and dental issues, contributing to decreased health-related quality of life (HRQoL). HPP may be treated with the enzyme replacement therapy asfotase alfa though real-world data in adults are limited. This analysis was conducted to assess the clinical effectiveness of asfotase alfa among adults in the Global HPP Registry.

METHODS

The Global HPP Registry is an observational, prospective, multinational study. Adults ≥ 18 years of age were included in this analysis if they had serum alkaline phosphatase (ALP) activity below the age- and sex-adjusted reference ranges, and/or ALPL variant(s), and received asfotase alfa for ≥ 6 months. Mobility was assessed with the 6-Minute Walk Test (6MWT), and patient-reported outcomes tools were used to assess pain (Brief Pain Inventory-Short Form), quality of life (36-item Short Form Health Survey, version 2 [SF-36v2]), and disability (Health Assessment Questionnaire-Disability Index) at multiple time points from baseline through Month 36. Data were collected as per usual standard of care; patients may not have contributed data at all time points.

RESULTS

A total of 190 patients met the inclusion criteria. For patients with ≥ 1 follow-up measurement, the mean distance achieved on 6MWT increased from 404 m (range 60-632 m) at baseline (n = 31) to 484 m at Month 12 (range 240-739 m; n = 18) and remained above baseline through Month 36 (n = 7). Improvements in mean self-reported pain severity scores ranged from - 0.72 (95% CI: - 1.23, - 0.21; n = 38) to - 1.13 (95% CI: - 1.76, - 0.51; n = 26) and were observed at all time points. Improvements in the Physical Component Summary score of SF-36v2 were achieved by Month 6 and sustained throughout follow-up. There was a trend toward improvement in the Mental Component Summary score of SF-36v2 at most time points, with considerable fluctuations from Months 12 (n = 28) through 36 (n = 21). The most frequent adverse events were injection site reactions.

CONCLUSIONS

Adults with HPP who received asfotase alfa for ≥ 6 months experienced improvements in mobility, physical function, and HRQoL, which were maintained over 3 years of follow-up.

QuickDASH and PRWE Are Not Optimal Patient-Reported Outcome Measures After Distal Radial Fracture Due to Ceiling Effect: Potential Implications for Future Research

BACKGROUND

The aim of this study was to determine the floor and ceiling effects for both the QuickDASH (shortened version of the Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire) and the PRWE (Patient-Rated Wrist Evaluation) following a distal radial fracture (DRF). Secondary aims were to determine the degree to which patients with a floor or ceiling effect felt that their wrist was "normal" according to the Normal Wrist Score (NWS) and if there were patient factors associated with achieving a floor or ceiling effect.

METHODS

A retrospective cohort study of patients in whom a DRF was managed at the study center during a single year was undertaken. Outcome measures included the QuickDASH, PRWE, EuroQol-5 Dimensions-3 Levels (EQ-5D-3L), and NWS.

RESULTS

There were 526 patients with a mean age of 65 years (range, 20 to 95 years), and 421 (80%) were female. Most patients were managed nonsurgically (73%, n = 385). The mean follow-up was 4.8 years (range, 4.3 to 5.5 years). A ceiling effect was observed for both the QuickDASH (22.3% of patients with the best possible score) and the PRWE (28.5%). When defined as a score that differed from the best available score by less than the minimum clinically important difference (MCID) for the scoring system, the ceiling effect increased to 62.8% for the QuickDASH and 60% for the PRWE. Patients who had a ceiling score on the QuickDASH and the PWRE had a median NWS of 96 and 98, respectively, and those who had a score within 1 MCID of the ceiling score reported a median NWS of 91 and 92, respectively. On logistic regression analysis, a dominant-hand injury and better health-related quality of life were the factors associated with both QuickDASH and PRWE ceiling scores (all p < 0.05).

CONCLUSIONS

The QuickDASH and PRWE demonstrate ceiling effects when used to assess the outcome of DRF management. Some patients achieving ceiling scores did not consider their wrist to be "normal." Future research on patient-reported outcome assessment tools for DRFs should aim to limit the ceiling effect, especially for individuals or groups that are more likely to achieve a ceiling score.

Association of Open Reduction and Internal Fixation With Volar Locking Plate for Distal Radius Fractures With Patient-Reported Outcomes in Older Adults: A Network Meta-analysis

Importance

Randomized clinical trials (RCTs) and meta-analyses have reported inconsistent conclusions regarding optimal distal radius fracture (DRF) treatment in older adults and are limited due to the inclusion of cohort studies with small sample sizes. A network meta-analysis (NMA) addresses these limitations by only synthesizing direct and indirect evidence from RCTs and may clarify optimal DRF treatment in older adults.

Objective

To examine DRF treatment results in optimal short-term and intermediate-term patient-reported outcomes.

Data Sources

Searches of MEDLINE, Embase, Scopus, and Cochrane Central Register of Controlled Trials were conducted for RCTs that investigated DRF treatment outcomes in older adults between January 1, 2000, and January 1, 2022.

Study Selection

Randomized clinical trials including patients with a mean age of 50 years or older that compared the following DRF treatments were eligible for inclusion: casting, open reduction and internal fixation with volar lock plating (ORIF), external fixation, percutaneous pinning, and nail fixation.

Data Extraction and Synthesis

Two reviewers independently completed all data extraction. An NMA aggregated all direct and indirect evidence among DRF treatments. Treatments were ranked by surface under the cumulative ranking curve score. Data are reported as standard mean differences (SMDs) and 95% CIs.

Main Outcomes and Measures

The primary outcome was short-term (≤3 months) and intermediate-term (>3 months to 1 year) Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire scores. Secondary outcomes included Patient-Rated Wrist Evaluation (PRWE) scores and 1-year complication rates.

Results

In this NMA, 23 RCTs consisting of 3054 participants (2495 women [81.7%]) with a mean (SD) age of 66 (7.8) years were included. At 3 months, DASH scores were significantly lower for nail fixation (SMD, -18.28; 95% CI, -29.93 to -6.63) and ORIF (SMD, -9.28; 95% CI, -13.90 to -4.66) compared with casting. The PRWE scores were also significantly lower for ORIF (SMD, -9.55; 95% CI, -15.31 to -3.79) at 3 months. In the intermediate term, ORIF was associated with lowered DASH (SMD, -3.35; 95% CI, -5.90 to -0.80) and PRWE (SMD, -2.90; 95% CI, -4.86 to -0.94) scores. One-year complication rates were comparable among all treatments.

Conclusions and Relevance

The findings of this NMA suggest that ORIF may be associated with clinically significant improvements in short-term recovery compared with casting for multiple patient-reported outcomes measures with no increase in 1-year complication rates. Shared decision-making with patients may be useful to identify patient preferences regarding recovery to determine optimal treatment.

Functional recovery with peripheral nerve block versus general anesthesia for upper limb surgery: a systematic review

BACKGROUND

Peripheral nerve block is a common anesthetic technique used during orthopedic upper limb surgery. Injection of local anesthetics around the target nerve inhibits the action of voltage-dependent sodium channels, inhibiting neurotransmission of pain impulses and providing motor immobility. Compared to general anesthesia, it could improve functional recovery by inhibiting nociceptive impulses and inflammation, thus reducing postoperative pain and immobilization and improving postoperative rehabilitation. This systematic review evaluates the impact of peripheral nerve block versus general anesthesia on postoperative functional recovery following orthopedic upper limb surgery.

METHODS

We searched CENTRAL, MEDLINE, CINHAL, EMBASE, and Scopus trial databases from inception until September 2021 for studies comparing peripheral nerve block to general anesthesia. We collected data on functional recovery, range of motion, patient satisfaction, quality of life, and return to work. We pooled studies using a random-effects model and summarized the quality of evidence with the GRADE approach.

RESULTS

We assessed 373 citations and 19 full-text articles for eligibility, and included six studies. Six studies reported on functional recovery, but failed to detect a significant superiority of peripheral nerve block over general anesthesia (3 RCT studies, N = 160; SMD -0.15; CI at 95% -0.60-0.3; I² = 45%; p = 0.07; low quality of evidence and 3 observational studies, N = 377; SMD -0.35; CI at 95% -0.71-0.01; I² = 64%; p = 0.06; very low quality of evidence).

CONCLUSIONS

Current literature is limited and fails to identify the benefit of peripheral nerve block on functional recovery. More studies are needed to assess the impact on long-term recovery. Considering the potential impact on clinical practice and training, a prospective study on functional recovery is ongoing (NCT04541745).

Functional outcome measures for distal radius fractures: A systematic review

Objective: This systematic review aimed to identify and describe the utility of functional outcome measures reported in intervention trials between 2010 and 2020, and to map these measures to the International Classification of Functioning, Disability and Health (ICF) model.

Method: The search was carried out on MEDLINE, CINAHL and Cochrane Register of Clinical Trials. Peer-reviewed intervention studies detailing the functional outcome measures used for any treatment for distal radius fracture were selected. Participant characteristics, outcome measures reported and the trends in their use over time and geographical locations were extracted.

Results: This review analysed 119 studies. Thirty-one functional outcome measures were used across 36 countries. Ninety-two percent of studies measured both the Body Function/Structure and Activity/Participation domains of the ICF. The most frequently used measures were the Disabilities of the Arm, Shoulder and Hand Questionnaire, Range of Motion and Grip Strength. There is a lack of measures on successful return to meaningful occupation.

Conclusion: The outcome measures identified were equally spread across the ICF domains. There is a growing importance of Patient-Reported Outcome Measures to supplement performance-based measures, but a lack of measure on successful return to meaningful occupation.
