Which of the following is NOT a common complication of harvesting an autologous bone graft from the iliac crest?

Harvesting an autologous bone graft from the iliac crest is commonly associated with several complications, including pain, infection, and fracture. The correct choice is that immobility is not typically considered a direct complication of this procedure.

When a bone graft is harvested, pain at the donor site is expected due to the invasive nature of the procedure. Infection is also a recognized risk, as with any surgical intervention, particularly in an area that may be exposed during the operation. Fracture can occur due to weakening of the bone at the iliac crest after grafting, although this is not as common.

However, immobility is not a direct complication stemming from the harvest of an iliac crest bone graft. While a patient may experience some decreased mobility postoperatively due to pain or discomfort, this is not a complication inherent to the grafting procedure itself, but rather a temporary state related to recovery. Typically, patients are encouraged to gradually regain their mobility to promote healing and prevent complications from prolonged immobility, such as deep vein thrombosis. Therefore, immobility does not fit the context of common complications associated with harvesting from the iliac crest.
