However, delayed repairs can end up with poor functional outcome such as contracture or atrophy similar to our case.15Patients with prolonged ischemia have a risk of renal failure due to increased levels of myoglobin and its products which can be avoided with good hydration and mannitol preoperatively, intraoperatively, and postoperatively.3Due to delayed presentation in our second patient, to avoid renal complications, we infused injection mannitol 100mL thrice a day for 5 days from the day of arrival to our hospital and hydrated with fluids 100mL per hour for 7 days. The gene discussed is MB; the disease is Renal insufficiency.
