A sequestrectomy is a surgical procedure aimed at removing a sequestrum, which is a segment of necrotic (dead) bone that has detached from the surrounding healthy bone tissue. This procedure is typically indicated in cases of osteomyelitis, an infection of the bone, or a bone abscess, which is a localized collection of pus within the bone. The sequestrectomy can be performed on various bones, including the clavicle, scapula, and humeral head to neck, with CPT® Code 23172 specifically referring to the procedure performed on the scapula. During the operation, an incision is made through the skin and soft tissue to access the affected area. If the periosteum, the layer of tissue covering the bone, is healthy, it is carefully lifted away from the sequestrum to allow for the excision of the necrotic bone. In cases where the periosteum is not viable, the surgeon may find that new bone, known as involucrum, has developed around the sequestrum. In such instances, the necrotic bone is removed while preserving the involucrum, which will aid in the healing process and contribute to the formation of new bone in the area of the cortical bone defect. After the necrotic tissue is excised, the incisions in the soft tissue and skin are closed, and a dressing is applied to protect the surgical site during the recovery period.

The sequestrectomy procedure is indicated for the following conditions:
The sequestrectomy procedure involves several critical steps to ensure the effective removal of the necrotic bone.
After the sequestrectomy, patients can expect a recovery period that may involve monitoring for signs of infection and managing pain. The surgical site will require proper care, including keeping the dressing clean and dry. Follow-up appointments will be necessary to assess healing and ensure that the bone is regenerating appropriately. Rehabilitation may also be recommended to restore function and strength in the affected area.
