Transtibial Amputation
Pronunciation: trans-TIB-ee-al
Surgical removal of the lower limb below the knee, preserving the tibia and fibula remnant.
Full Definition
Transtibial amputation, formerly referred to as below-knee (BK) amputation, describes surgical removal of the foot and lower leg at a level distal to the knee joint, with preservation of part of the tibia and fibula. Modern clinical and editorial style favours the 'trans-' prefix terminology (transtibial, transfemoral) over older directional descriptors such as 'below-knee' or 'above-knee,' though both forms appear in literature and editors should apply the style guide consistently. The residual limb created is called the 'transtibial residual limb' or 'below-knee stump,' though 'stump' is increasingly avoided in patient-centred documentation.
Usage
Usage note: Preferred over 'below-knee amputation' in contemporary clinical writing. Check the house style guide to ensure consistent use of 'transtibial' vs 'below-knee' throughout the document.
