An osteotomy of the calcaneus is a surgical procedure that involves cutting and reshaping the heel bone, known as the calcaneus, to correct deformities or misalignments. This procedure can be performed with or without the use of internal fixation devices, which are tools used to stabilize the bone after it has been cut. The osteotomy may be specifically categorized as a Dwyer or Chambers type procedure, which refers to the specific techniques used to achieve the desired correction. During the surgery, the surgeon makes an incision either on the lateral (outer) or medial (inner) side of the foot, depending on the specific nature of the calcaneal deformity being addressed. Once the calcaneus is exposed, care is taken to protect the underlying tendons and soft tissues. The procedure involves the removal of a wedge of bone from the calcaneus, which can be done using a surgical saw or an osteotome, a specialized surgical instrument. After the wedge is removed, the heel is realigned by closing the wedge, and fixation devices such as pins or screws may be used to maintain this alignment. In cases where an opening wedge osteotomy is performed, the process involves creating an opening in the bone, inserting a laminar spreader to maintain the gap, and placing a bone graft—either from a donor (allograft) or the patient’s own body (autograft)—to fill the defect. This procedure is essential for correcting various foot deformities and improving overall foot function.
