摘要

Purpose

To translate palmaris longus (PL) morphological variability into an operational, clinically usable risk framework that unifies anatomy, imaging, and surgery.

Methods

Narrative review and framework development. Building on contemporary anatomical classification of the PL, we define a three-level clinical-risk (CR) stratification (CR-1/CR-2/CR-3) that couples type/subtype with the relationship to the median nerve. We specify a minimal reporting core for ultrasound and MRI (Imaging Minimum Dataset) and develop two concise clinical pathways: a diagnostic workflow and a harvest decision tree. No new patient data were collected.

Results

The framework standardises radiological reporting by requiring explicit statement of presence, type/subtype, nerve relations, and estimated graftable length, culminating in a CR designation. This shared language links imaging outputs directly to operative planning, clarifies when decompression is indicated, and identifies when the PL is an appropriate donor versus when alternatives should be preferred. The pathways distil key safeguards to reduce misidentification and protect the median nerve while maintaining procedural efficiency.

Conclusions

A risk-oriented reinterpretation of PL variability provides a clear bridge from anatomy to imaging and surgery. The CR framework and associated pathways support consistent reporting, safer tendon harvest, and targeted decompression, and they are suitable for prospective validation of reproducibility, imaging–surgery concordance, and patient-centred outcomes.
