Arthroscopic release of the extensor carpi radialis brevis tendon is a safe procedure for refractory lateral epicondylitis. Cadaveric dissection confirmed no direct neurovascular damage, though superficial nerves are at risk.

Area of Science:

  • Orthopedic Surgery
  • Minimally Invasive Procedures
  • Anatomy

Background:

  • Refractory lateral epicondylitis has multiple surgical treatments.
  • Arthroscopic release of the extensor carpi radialis brevis tendon offers potential advantages.
  • These include joint examination, preserved extensor mechanism, and faster recovery.

Purpose of the Study:

  • To evaluate the safety of arthroscopic release of the extensor carpi radialis brevis tendon.
  • To assess potential risks to neurovascular structures during the procedure.

Main Methods:

  • Ten fresh-frozen cadaveric upper extremities were used.
  • Arthroscopic visualization and release of the extensor carpi radialis brevis tendon were performed.
  • Cadaveric dissection identified distances between portals/cannula tracks and surrounding neurovascular structures.

Main Results:

  • No direct lacerations of neurovascular structures were observed.
  • The radial nerve was consistently near the proximal lateral portal (mean 5.4 mm).
  • Superficial sensory nerves (lateral and posterior antebrachial) are at risk during portal placement.

Conclusions:

  • Arthroscopic release of the extensor carpi radialis brevis tendon is a safe and reproducible option for refractory lateral epicondylitis.
  • Cadaveric dissection supports the safety of this minimally invasive approach.
  • Careful portal placement is necessary to mitigate risks to superficial nerves.
