Background and purposeDuring the last decades, treatment of distal radius fractures (DRFs) has changed, with surgical intervention being more common and with new techniques. We investigated whether this change has influenced the subjective outcome. Here we report, year by year, the 1-year score after a DRF over a 10-year-period, using a patient-reported outcome measure.Patients and methodsPatients aged 18 years or more with a DRF between 2003 and 2012 were prospectively and consecutively registered in a longitudinal outcome database. 1 year after the fracture, all the patients were sent a validated subjective outcome questionnaire, the Disabilities of the Arm, Shoulder, and Hand (DASH). The lower the score (0–100), the better the outcome.ResultsBetween 2003 and 2012, 3,666 patients (2,833 of them women; mean age 62 (18–98) years) were included. 22% were operated and the rate remained constant over the years. The surgical methods shifted from external fixators (42%) and fragment-specific plates (45%) in 2003, to mainly volar locking plates (65%) in 2012. 70% of the patients responded to the 1-year DASH questionnaire. The median DASH score was 9 (IQR: 2–25) for the cohort, both in surgically treated patients (9 (IQR: 3–25)) and in non-surgically treated patients (9 (IQR 2–27)). Subgroup analysis showed a higher median DASH score for women than for men; for patients with AO type C fractures rather than type B or type A fractures; for patients with external fixation or fragment-specific fixation than for those who underwent surgery using volar locking plates; and for patients who were operated by a general orthopedic surgeon rather than a hand surgeon.InterpretationThe shift in surgical treatment had no influence on the subjective outcome for the cohort.

Background and purposeWe have previously shown in a randomized study that in the first year after treatment, open reduction and internal fixation resulted in better grip strength and forearm rotation than closed reduction and bridging external fixation. In the present study, we investigated whether this difference persists over time.Patients and methodsThe 50 patients included in the original study (mean age 53 years, 36 women) were sent a QuickDASH questionnaire and an invitation to a radiographic and clinical examination after a mean of 5 (3–7) years.ResultsAll 50 patients returned the QuickDASH questionnaire and 45 participated in the clinical and radiographic examination. In the internal fixation group, the grip strength was 95% (SD 12) of the uninjured side and in the external fixation group it was 90% (SD 21) of the uninjured side (p = 0.3). QuickDASH score, range of motion, and radiographic parameters were similar between the groups.InterpretationThe difference originally found between internal and external fixation in distal radial fractures at 1 year regarding grip strength and range of motion was found to diminish with time. At 5 years, both groups had approached normal values.

Background and purpose: A better understanding of factors that influence functioning may improve the identification of patients with distal radius fractures (DRFs) who need hand therapy. The purpose of this scoping review was to provide a comprehensive overview of factors that have been evaluated for their influence on hand functioning following volar plate fixation of DRFs.Material and methods: 6 databases were searched from 2005 to 2021 for publications regarding surgical treatment for a DRF with a volar locking plate. Included studies evaluated demographic, perioperative, and postoperative factors within the 6 weeks post-surgery for their influence on functioning at least 3 months post-surgery. Functioning was assessed with patient-reported outcome measures. The factors were categorized into themes and mapped to the International Classification of Functioning, Disability and Health (ICF).Results: 148 studies were included. 708 factors were categorized into 39 themes (e.g. pain) and mapped to the ICF components. The themes were primarily mapped to “body functions and structures” (n = 26) and rarely to “activities and participation” (n = 5). Fracture type (n = 40), age (n = 38), and sex (n = 22) were the most frequently evaluated factors.Conclusion: This scoping review identified an extensive number of factors evaluated within 6 weeks after surgery for their influence on functioning at least 3 months after volar plate fixation of a DRF and the existing research has primarily evaluated factors related to “body functions and structures,” with limited focus on factors related to “activities and participation.”

Resumo Objetivo Este estudo avaliou diferenças entre parafusos com rosca total ou parcial na resistência à compressão interfragmentar inicial. Nossa hipótese era de que haveria maior perda de resistência à compressão inicial com o parafuso de rosca parcial. Métodos Uma linha de fratura oblíqua de 45 graus foi criada em amostras de osso artificial. O primeiro grupo (TOTAL, n = 6) foi fixado com um parafuso de 3,5 mm de rosca total, enquanto o segundo grupo (PARCIAL, n = 6) usou um parafuso de 3,5 mm de rosca parcial. Avaliamos a rigidez à torção em ambas as direções de rotação. Os grupos foram comparados com base nos seguintes parâmetros biomecânicos: momento de rigidez-ângulo, momento de rigidez-tempo, momento de torção máxima (carga de falha) e força de compressão calibrada com base na medida do sensor de pressão. Resultados Depois da perda de uma amostra PARCIAL, não foram observadas diferenças estatisticamente significativas na força de compressão calibrada entre os 2 grupos [mediana (intervalo interquartil)]: TOTAL: 112,6 (10,5) N e PARCIAL: 106,9 (7,1) N, com p = 0,8 segundo o teste U de Mann-Whitney). Além disso, após a exclusão de 3 amostras para testes mecânicos (TOTAL, n = 5, PARCIAL, n = 4), não foram observadas diferenças estatisticamente significativas entre os construtos TOTAL e PARCIAL quanto ao momento de rigidez-ângulo, momento de rigidez-tempo ou momento de torção máxima (carga de falha). Conclusão Não há diferença aparente na força de compressão inicial (força de compressão ou rigidez do construto ou carga de falha) com o uso de parafusos de rosca total ou parcial neste modelo biomecânico em osso artificial de alta densidade. Parafusos de rosca total podem, portanto, ser mais úteis no tratamento de fraturas diafisárias. Mais pesquisas são necessárias sobre o impacto em modelos ósseos osteoporóticos ou metafisários de menor densidade e avaliação do significado clínico.
