Moore osteotomy-osteoclasis. A, 1, Wedge has been resected from normal bone distal to malunion, leaving cortex on concave side of deformity intact; proximal cut is perpendicular to long axis of proximal fragment, and distal cut is perpendicular to that of distal fragment. 2, Grafts have become consolidated with early callus. 3, Deformity has been corrected by manual osteoclasis. B, Detail of technique. Wedge of bone is removed and is cut into chips that are placed back into defect; periosteum is carefully sutured. C, At 3 to 4 weeks after surgery, section of cast is removed and deformity is corrected manually. Cast is repaired with plaster.
