Typical Clinical Scenarios

A 28-year-old male sustains a high-energy open midshaft humeral fracture with a large associated soft-tissue defect after a motorcycle collision. During the same admission, orthopedic and plastic surgery teams perform debridement and reconstruct the lost left upper arm muscle bulk and function using the patient's own fascia and muscle graft harvested from the latissimus dorsi, implanted through an open surgical approach. A replacement procedure is performed to restore muscle continuity and improve arm strength and contour. Typical codes: 0KR807Z
A 62-year-old woman with a chronic, nonfunctional deltoid and biceps complex due to radiation fibrosis following prior shoulder cancer therapy elects reconstructive surgery to restore upper arm function. In a planned inpatient operation, a synthetic muscular implant is placed into the left upper arm via an open approach to substitute the fibrosed muscle tissue and allow improved limb use. The procedure is elective and performed when conservative measures have failed. Typical codes: 0KR80JZ
A 45-year-old man presents with progressive contracture and poor function months after a previous allograft muscle reconstruction for a left arm tumor excision; imaging shows partial graft failure and scar causing pain and limited range of motion. During an inpatient revision, surgeons remove the failed nonautologous graft material and replace it with a new nonautologous tissue substitute using an open approach to reestablish muscle bulk and function. The operation addresses the complication of prior graft failure and aims to salvage limb function. Typical codes: 0KR80KZ
