Scapulothoracic Arthroscopy for Snapping Scapula Syndrome

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Arthroscopy

Background:

• Snapping scapula syndrome (SSS) disrupts normal scapulothoracic joint motion, causing audible clicking or snapping.
• Etiologies vary, with conservative treatments being the initial approach.
• Surgical intervention is considered for cases unresponsive to extensive nonoperative management.

Purpose of the Study:

• To describe the arthroscopic surgical technique for treating snapping scapula syndrome.
• To evaluate the efficacy of arthroscopic bursectomy and partial scapular resection.

Main Methods:

• A prone patient position is utilized with the operative arm positioned posteriorly.
• Two arthroscopic portals are established: a superior portal (3 cm medial to the scapular border) and an inferior portal (4 cm inferior to the superior portal).
• Arthroscopic shaver, ablator, and bur are employed for bursectomy and partial resection of the superomedial scapular border.

Main Results:

• Limited studies exist, but current literature indicates scapulothoracic arthroscopy effectively improves crepitus and pain.
• The procedure aims to enhance clinical outcome scores in patients with SSS.

Conclusions:

• Arthroscopic bursectomy and partial bony resection are effective for SSS refractory to conservative therapy.
• This minimally invasive approach offers improved cosmesis and facilitates an early return to activities.
• Meticulous patient positioning and portal placement are crucial to prevent iatrogenic injuries, especially to neural structures.
