Official Description

Ostectomy of scapula, partial (eg, superior medial angle)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Partial ostectomy of the scapula, as defined by CPT® Code 23190, is a surgical procedure aimed at removing a portion of the scapula, which is the bone commonly referred to as the shoulder blade. This procedure is typically indicated for patients experiencing pain, deformity, lesions, or other pathological conditions affecting the scapula. The superior medial angle of the scapula is a frequently targeted area for resection during this operation. The procedure begins with a skin incision made in the upper back, directly over the affected area of the scapula. Following the incision, the surgeon carefully dissects the soft tissues to access the scapula, ensuring minimal damage to surrounding structures. Once the site of deformity or lesion is adequately exposed, the surgeon excises the diseased bone or any bony overgrowth. This excised tissue is often sent for a pathology examination to assess the nature of the lesion. After the removal of the affected bone, the remaining bone surface is smoothed to promote healing and reduce discomfort. Finally, the overlying soft tissues and skin are meticulously closed in layers to ensure proper healing and minimize scarring.

1. Indications

Partial ostectomy of the scapula is performed for various indications, primarily related to conditions affecting the scapula that may cause pain or functional impairment. The following are the explicitly provided indications for this procedure:

  • Pain - Patients experiencing significant discomfort in the shoulder region that may be attributed to scapular pathology.
  • Deformity - Structural abnormalities of the scapula that may affect shoulder function or aesthetics.
  • Lesion - Presence of abnormal growths or lesions on the scapula that require removal for diagnostic or therapeutic purposes.
  • Other disease of the bone - Various pathological conditions affecting the scapula that necessitate surgical intervention.

2. Procedure

The procedure for partial ostectomy of the scapula involves several critical steps, each designed to ensure the effective removal of the affected bone while preserving surrounding structures. The following outlines the procedural steps:

  • Step 1: Skin Incision - The procedure begins with the surgeon making a precise skin incision in the upper aspect of the back, directly over the area of the scapula that is affected. This incision is strategically placed to provide optimal access to the underlying bone while minimizing trauma to surrounding tissues.
  • Step 2: Dissection of Soft Tissues - Following the incision, the surgeon carefully dissects the soft tissues, including muscles and fascia, to expose the scapula. This step requires meticulous attention to avoid damaging nerves and blood vessels in the vicinity.
  • Step 3: Exposure of the Scapula - Once the soft tissues are retracted, the site of deformity or lesion on the scapula is fully exposed. This allows the surgeon to assess the extent of the disease and determine the appropriate area for resection.
  • Step 4: Resection of Diseased Bone - The surgeon then excises the diseased bone or bony overgrowth. This excised tissue is typically sent for a separate pathology examination to evaluate the nature of the lesion and rule out malignancy.
  • Step 5: Smoothing of Remaining Bone - After the removal of the affected portion, the remaining bone surface is smoothed to promote healing and reduce the risk of post-operative complications, such as pain or discomfort.
  • Step 6: Closure of Soft Tissues - Finally, the overlying soft tissues and skin are closed in layers. This layered closure technique helps to ensure proper healing and minimizes scarring at the incision site.

3. Post-Procedure

Post-procedure care following a partial ostectomy of the scapula typically involves monitoring for any signs of complications, such as infection or excessive bleeding. Patients may be advised to limit shoulder movement for a specified period to allow for proper healing. Pain management strategies, including medications, may be implemented to ensure patient comfort during the recovery phase. Follow-up appointments are essential to assess the healing process and to evaluate the need for any additional interventions or rehabilitation to restore shoulder function.
