Medial hip arthroscopy portals: an anatomic study.

Area of Science:

• Orthopedic surgery
• Anatomy
• Surgical techniques

Background:

• Medial hip portals are increasingly utilized for hip arthroscopy.
• Understanding the precise anatomical relationships of these portals is crucial for surgical safety.

Purpose of the Study:

• To investigate three medial hip portals.
• To evaluate their relationship with surrounding anatomical structures using a cadaveric model.

Main Methods:

• Simulated placement of three medial arthroscopic portals in 10 cadaveric hip specimens.
• Used fluoroscopic control for pin placement.
• Performed detailed dissection to record portal proximity to key neurovascular and muscular structures.

Main Results:

• The anteromedial portal was closest to the profunda femoris artery (10.4 mm).
• The posteromedial portal was nearest the obturator nerve (6.0 mm).
• The distal posteromedial portal was closest to the obturator nerve (4.6 mm) and profunda femoris artery (10.5 mm).

Conclusions:

• No neurovascular damage was observed with the evaluated medial hip portals.
• These portals are in close proximity to the obturator nerve and profunda femoris artery.
• Medial hip portals offer a viable approach for medial hip pathologies with careful consideration of safety parameters.
