Manipulation of Distal Radius Fractures: A Comparison of Bier’s block Vs Haematoma Block

Description

Ben Oakley, an orthopedic registrar from the East Midlands North Rotation, discusses variations in the method of anesthesia used for reducing distal radius fractures. He presents findings from a survey conducted in over 100 departments nationwide, highlighting that the most common method utilized is the hematoma block, which contradicts national guidance favoring the bier block. Despite some evidence suggesting the latter's superiority, Ben notes a lack of robust data from the early studies that primarily inform current practice.



The study he outlines involved comparing two hospitals with different management protocols: one used hematoma blocks in the emergency department, while the other preferred bier blocks, typically administered by junior doctors. Ben elaborates on the methodology, which included excluding patients with additional injuries or cognitive impairments, and measuring outcomes including pain relief effectiveness and radiographic results post-manipulation.



The demographics revealed a cohort of primarily elderly patients with fragility fractures. The study indicated that those receiving bier blocks experienced lower fat scores and higher success rates in achieving normal anatomical parameters upon fracture manipulation. Regression analysis suggested that the bier block maintain its effectiveness even when considering other patient demographics.



In conclusion, Ben emphasizes the potential benefits of bier blocks in terms of pain relief and successful fracture reduction, while advising caution in interpreting the results, attributing variability to confounding factors. He notes that treatment discretion by clinicians and the non-randomized nature of the study reflects real-world practices, underlining the complexities involved in orthopedic treatment strategies.
