Summary
This study details endoscopic radial tunnel release for treating radial tunnel syndrome and posterior interosseous nerve syndrome. This minimally invasive surgery effectively decompressess potential entrapment sites.
Area of Science:
- Orthopedic Surgery
- Neuroscience
- Minimally Invasive Procedures
Background:
- Radial tunnel syndrome and posterior interosseous nerve syndrome are compression neuropathies of the radial nerve.
- Entrapment can occur due to several structures within the radial tunnel, including fibrous bands, leash of Henry, extensor carpi radialis brevis, and the arcade of Frohse.
Purpose of the Study:
- To describe the technique of endoscopic radial tunnel release.
- To present a minimally invasive surgical approach for radial nerve decompression.
Main Methods:
- Endoscopic visualization and release of potential radial tunnel entrapment sites.
- Focus on decompressing fibrous bands, leash of Henry, extensor carpi radialis brevis, and arcade of Frohse.
Main Results:
- Endoscopic radial tunnel release can address all identified potential entrapment sites.
- This approach offers a minimally invasive solution for refractory cases.
Conclusions:
- Endoscopic radial tunnel release is an effective technique for managing radial tunnel syndrome and posterior interosseous nerve syndrome.
- Minimally invasive surgery provides a viable option for patients with symptoms unresponsive to nonoperative treatments.

01:21G-Protein Gated Ion Channels
GPCRs are primarily responsible for our sense of smell, taste, and vision. The binding of a sensory stimulus activates GPCR to stimulate effector proteins, many of which are ion channels in the sensory organs. GPCRs modulate the opening and closing of the target ion channels either directly by binding them, or by releasing second messengers that activate these channels. As ions move across the membrane, the membrane potential is altered, which induces an appropriate response.

01:05Total Internal Reflection Fluorescence Microscopy
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.
