MANIPULATION OF DISTAL RADIUS FRACTURES IN A&E: OUTCOME DEPENDS ON THE TYPE OF ANAESTHESIA USED AND THE EXPERIENCE OF THE PERFORMER

To determine the effect of experience of the operator and the effect of type of anaesthesia used on re-manipulation rates of fracture distal radius manipulated in A&E, a retrospective review of distal radius fractures manipulated in A&E between January 2000 and January 2001. Operators were divided into two categories: junior (SHO grade) and senior (higher grade) doctor. 54 patients with fracture distal radius had manipulation in A&E. 15 male and 39 female patients with mean age of 61 years (52 for males and 63 for females) were included. 42 (78%) fractures were manipulated under haematoma block (18 by junior, 23 by senior doctor) and 12 (22%) fractures were manipulated under Bier block (1 by junior, 11 by senior doctor). Operator’s grade was not clearly mentioned in one case. 13 out of 54 patients (24%) needed fracture re-manipulation under general anaesthesia. 12 out of 42 fractures manipulated under haematoma block (30%) needed re-manipulation compared to only one out of 12 fractures (8%) manipulated under Bier block (p=0.25). 9 out of 19 fractures manipulated by junior doctors needed re-manipulation compared to only 4 out of 34 fractures manipulated by senior doctors (p=0.007). Haematoma block was used for 18 out of 19 cases by junior doctors and for 23 out of 34 cases by senior doctors (p=0.038). Average number of fracture clinic follow-ups was 4 (range 2 to 8). Junior doctors had significantly higher preference for haematoma block and significantly higher re-manipulation rate. Re-manipulation rates were higher with fractures manipulated under haematoma block compared to Bier block. Adequate training and supervision should be provided for SHOs while performing such procedures in A&E. Use of Bier block as a regional anaesthesia for manipulation of distal radius fractures in A&E should be encouraged.
