Surgical experience and supervision may influence the quality of lower limb amputation.
OBJECTIVE
Only half of those patients undergoing major lower limb amputations for peripheral vascular disease (PVD) are likely to mobilise on a prosthesis. This study aimed to determine whether a surgeon's experience influenced the quality of the residual limb and thus the likelihood of the stump being suitable for a prosthesis.


METHODS
All patients undergoing major lower limb amputations for PVD were recruited prospectively, between August 1992 and July 1996. Following surgery, patients were categorised, by a consultant in rehabilitation medicine, as potentially suitable (group 1) or unsuitable (group II) for rehabilitation. Patients in group I were further assessed by prosthetists for limb fitting.


RESULTS
A total of 217 patients underwent 260 amputations for PVD between 1992 and 1996: transfemoral (TFA) 131, trans-tibial (TTA) 127, and through-knee (TKA) in 2. The 30-day mortality was 12% (n = 27). Following surgery, 109 patients were assigned to group I (51%), and 81 patients to group II (37%). The proportion of junior surgeons performing surgery was similar for patients in both groups. Twenty-three amputation stumps (9%) required revision or conversion to a higher level within 30 days. Revisions or conversions were significantly more frequent where the original operation had been performed by an unsupervised junior surgeon rather than a senior surgeon (P = 0.009). The rate of defective amputations compromising limb fitting also reached significance when unsupervised junior and senior surgeons were compared (P = 0.04).


CONCLUSIONS
Rehabilitation of the relatively few amputees who reach the stage of limb fitting is hindered by poor surgical technique in a large proportion of cases. Patients operated on by a more experienced surgeon had a better chance of mobilising without revision or conversion surgery.
