[Arthroscopic decompression of extra-articular subspinal hip impingement]

Area of Science:

• Orthopedic Surgery
• Arthroscopy
• Hip Preservation

Background:

• Anterior hip impingement is often caused by hypertrophic osseous subspinal deformation.
• This condition can lead to painful anterior hip impingement and decreased hip flexion.

Purpose of the Study:

• To describe the arthroscopic technique for decompressing impinging subspinal soft tissues and resecting hypertrophic bone formations around the anterior inferior iliac spine (AIIS).
• To evaluate the outcomes of arthroscopic AIIS decompression for anterior hip impingement.

Main Methods:

• Hip arthroscopy performed in a supine position on an extension table.
• Arthroscopic decompression of soft tissues and resection of hypertrophic AIIS bone spurs using a shaver, radiofrequency device, or high-speed burr.
• Management of concurrent intra-articular hip pathologies.

Main Results:

• No comparative or long-term studies are available for arthroscopic AIIS decompression.
• Published case series indicate improvement in patient-reported outcome scores following the procedure.

Conclusions:

• Arthroscopic AIIS decompression is a viable option for symptomatic anterior hip impingement.
• Further research with comparative and long-term studies is needed to fully establish its efficacy.
