Anatomical Probability Model for Tibial and Peroneal Motor Entry Points
Sponsor: Research Inc
Summary
This completed descriptive cadaveric study mapped the motor entry points of lower-leg muscles supplied by the tibial, superficial peroneal, and deep peroneal nerves. Twenty fresh-frozen adult lower-limb specimens without prior trauma or surgery were examined. One extremity from each cadaver was selected by coin toss. Investigators performed standardized posterior, lateral, and anterior compartment dissections, followed each terminal motor branch to the point where it entered the target muscle, and measured its location relative to total leg length. For each muscle, motor entry point location was expressed as a proportion of leg length and summarized using the mean, standard deviation, and probability intervals corresponding to mean plus or minus one and two standard deviations. The study was designed to provide quantitative anatomical reference zones that may support surgical planning for hyperselective neurectomy and related lower-leg procedures.

Interventions
Standardized Cadaveric Lower-Limb Dissection
Standardized posterior, lateral, and anterior compartment dissections were performed. The tibial nerve was identified through the posterior approach. The common peroneal nerve was identified near the biceps femoris tendon and traced to its superficial and deep divisions. Motor branches were followed to their points of entry into the target muscles. The location of each motor entry point was measured relative to prespecified tibial or fibular landmarks and normalized to total leg length measured from the knee joint line to the ankle joint line.
