- Background: Semiconstrained total elbow arthroplasty (TEA) is an established treatment for elderly patients with distal humeral fractures not amenable to stable internal fixation (unreconstructable). In recent years, there has been increasing interest in elbow hemiarthroplasty (EHA), a treatment option which does not entail restrictions on weight-bearing as opposed to TEA. These 2 treatments have not been compared in a randomized controlled trial (RCT). The aim of this study was to compare the functional outcome of EHA and TEA for the treatment of unreconstructable distal humeral fractures in elderly patients. Material and methods: This was a multicenter randomized controlled trial (RCT). Patients were included between January 2011 and November 2019 at one of 3 participating hospitals. The inclusion criteria were an unreconstructable distal humeral fracture, age ≥60 years and independent living. The final follow-up took place after ≥2 years. The primary outcome measure was the Disabilities of the Arm, Shoulder, and Hand (DASH) score. Secondary outcome measures were the Mayo Elbow Performance Score (MEPS), the EQ-5D index, range of motion (flexion, extension, pronation, and supination) and grip strength. Results: Forty patients were randomized to TEA (n = 20) and EHA (n = 20). Five patients died before completing the final follow-up, leaving 18 EHA and 17 TEA patients for analysis. There were 31 women. The mean age was 74.0 (SD, 8.5) years in the EHA group and 76.9 (SD, 7.6) in the TEA group (P = .30). The mean DASH score was 21.6 points in the EHA group and 27.2 in the TEA group (P = .39), a difference of −5.6 points (95% CI: −18.6 to 7.5). There were no differences between treatment with EHA and TEA for the mean values of the MEPS (85.0 vs. 88.2, P = .59), EQ-5D index (0.92 vs. 0.86, P = .13), extension (29° vs. 29°, P = .98), flexion (126° vs. 136°, P = .05), arc of flexion-extension (97° vs. 107°, P = .25), supination (81° vs. 75°, P = .13), pronation (78° vs. 74°, P = .16) or grip strength (17.5 kg vs. 17.2 kg, P = .89). There were 6 adverse events in each treatment group. Conclusion: In this RCT, both elbow hemiarthroplasty (EHA) and total elbow arthroplasty (TEA) resulted in a good and similar functional outcome for unreconstructable distal humeral fractures in elderly patients at a minimum of 2 years of follow-up.

- Background: The Oxford Elbow Score (OES) is a well-validated, elbow-specific, patient-reported outcome measure (PROM), originally assigned a 4-week recall period. For PROMs, short recall periods could have some advantages, such as optimizing validity by minimizing the negative effects of inaccurate recollection and temporal trends (increase or decrease) in symptoms over the course of the recall period. Temporal trends in elbow function can, for example, be expected to occur over 4 weeks in patients recovering from an injury or surgery. The purpose of this study was to evaluate the measurement properties of the OES using a shortened, 7-day, recall period (OES-7d). Methods: The inclusion criteria were fracture, tendon rupture or dislocation affecting the elbow, and age ≥18 years. Patients with Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores of ≥10 points preinjury (pre-existing upper extremity condition) or concurrent upper extremity injuries were excluded. Patients completed the OES-7d, QuickDASH, and Single Assessment Numeric Evaluation-Function for the last 7 days preinjury (T1), the first 7 days postinjury (T2) and a 7-day period 3-5 months postinjury (T3). Correlations were assessed with Spearman's rho. Analyses of construct validity (correlation between scores) and internal consistency (Cronbach's alpha) were based on T3 data. Responsiveness was assessed by correlating changes in scores (change scores) between time points. Intra-rater reliability was assessed by calculating intraclass correlation coefficients based on 2 administrations (1- to 3-week interval) of PROMs in a separate group of patients who had sustained an elbow injury 1-2 years previously. Results: Seventy-five patients (45 women) were included between May 2020 and July 2021. Their mean age was 51.7 years. At T3, Spearman's rho was −0.91 for the correlation between OES total and QuickDASH scores and 0.76 for the correlation between OES total scores and Single Assessment Numeric Evaluation-Function values (construct validity). Spearman's rho for correlation between OES total and QuickDASH change scores from T2 to T3 (T3 minus T2) was −0.85 (responsiveness for improvement) and −0.88 for change scores from T1 to T2 (T2 minus T1, responsiveness for deterioration). For the OES domains, Cronbach's alpha was 0.83 for elbow function, 0.91 for pain and 0.90 for social-psychological domains. The intraclass correlation coefficient for the OES total score was 0.96. Conclusion: The OES demonstrated good measurement properties when used with a 7-day recall period (OES-7d). These results further establish the OES as a well-validated, elbow-specific PROM and support using a 7-day recall period.
