UDIN Surgical Technique ? SO328?907

Product catalog summary

Introduction
This document outlines the surgical technique for Uniportal Decompression of the Intermetatarsal Nerve as described by Gary M. Lepow, DPM, MS. The procedure involves a minimally invasive approach to relieve pressure on the intermetatarsal nerve.

Incision
A 1cm vertical incision is made in the web space to access the distal border of the deep Transverse Intermetatarsal Ligament (TIML).

Introduction of Endoscope
The 4 mm, 30° endoscope is introduced through a cannula to visualize the TIML. Sterile swabs may be used to clear fluid from the cannula.

Visualization of TIML
The transverse fibers of the TIML should be visible. If obscured, a rasp is used to clear the view. Proper placement of the endoscope is crucial for visualization.

Creating the Pathway
Blunt dissection is used to palpate the distal edge and plantar surface of the TIML. An elevator is introduced into the subligamentous space.

Introduction of Dissecting Cannula
The obturator/cannula assembly is introduced into the subligamentous space towards the TIML.

Blade Assembly
The scope-mounted blade is attached to the endoscope, oriented towards the blade for division of the TIML.

Division of TIML
The TIML is divided by advancing the blade through the cannula. Typically, one pass is sufficient.

Verification of Division
The scope is reintroduced to confirm complete division of the TIML.

Warnings and Precautions
The endoscopic blades are for single use only. Resterilization may cause blade detachment, posing a risk to the patient.

BLADE ASSEMBLY Attach the scope-mounted blade to the endoscope using the locking device (see diagram below), with the viewing angle of the endoscope oriented towards the blade. DIVISION OF TIML Introduce the scope-mounted blade into the cannula and, as you observe the monitor, divide the TIML by advancing the blade through the cannula in a proximal direction. It typically requires one pass to divide the TIML. VERIFICATION OF DIVISION Remove the scope-mounted blade from the endoscope and reintroduce the scope into the cannula. The divided edges of the TIML should now be visualized along its entire...
