Transfemoral interface considerations: A clinical consensus practice guideline.

BACKGROUND

Although there have been a number of studies exploring the impact and efficacy of transfemoral prosthetic components such as knee and foot mechanisms, the empirical evidence surrounding transfemoral prosthetic interface considerations is limited. This constitutes a substantial void for practicing clinicians seeking to apply best practices for patients who use transfemoral prostheses. Recent years have seen increased production and availability of clinical practice guidelines germane to prosthetic rehabilitation. In those areas where empirical evidence is lacking, consensus clinical opinions may constitute the highest level of evidence.

OBJECTIVE

A consensus exercise was performed to generate clinical practice recommendations in the areas of transfemoral interface considerations including socket variations and critical design features, suspension and interface considerations, alignment, heat retention and dermatologic considerations, female considerations, surgical considerations, and both regulatory and ethical considerations related to osseointegration.

METHODS

This began with the generation of postulate items through systematic and narrative literature reviews. A Delphi consensus exercise was performed among clinical experts in government hospital and private clinical practice settings, culminating in a series of clinical practice recommendations associated with the prosthesis-limb interface for individuals with transfemoral amputation.

RESULTS

The completed recommendations include guidance statements relative to socket variations and critical design features, female considerations, suspension and interface considerations, surgical variations and prescription considerations, rehabilitation team considerations and both regulatory and ethical considerations related to osseointegration.

CONCLUSIONS

The Delphi process facilitated the development of practice guidelines for transfemoral prosthetic interface considerations based on aggregated subject matter expertise.
