Transtibial
Pronunciation: trans-TIB-ee-ul
Describing an amputation or prosthetic fitting at a level below the knee, through the tibia.
Full Definition
The adjective 'transtibial' specifies that an amputation or prosthetic intervention occurs at a level distal to the knee joint, passing through or below the tibia. It has largely replaced the older clinical term 'below-knee (BK)' in formal documentation. Editors will find it in surgical operative notes, prosthetic prescriptions, functional outcome measures, and insurance coding submissions. The term is written as one unhyphenated word in standard clinical usage. It should not be confused with 'transfemoral,' which describes an above-knee level.
Usage
Usage note: One unhyphenated word. The colloquial abbreviation BK (below-knee) is acceptable in informal clinical notes but should be expanded on first use in formal documents.
