Objective To explore a safe, highlyefficient and rapid approach to the repair of the sacrum soft tissue defect and/or partial exposure of the bone.Methods From February 2003 to April 2006, 6 patients (4 males, 2 femals; aged 28-67 years) with the sacrum soft tissue defect were surgically treated by the multiisland flap with shallow branches of the gluteus upper artery. The soft tissue defects ranged in area from 15 cm×12 cm to 25 cm×20 cm,averaged 20 cm×16 cm.The obtained flaps ranged in area from 18 cm×15 cm to 30 cm×25 cm. Of the patients, 5 had a sacral ulcer (Grade Ⅲ in 3 patients, Grade Ⅳ in 2) and 1 had a tumor, with their illness course from 3weeks to 20 years. Results All the flaps survived completely in the 6 patients, in whom 5 had an incision healing of the first intention, and the remaining 1had a healing of the second intention 32 days after the treatment for the minorischemia and necrosis at the edges of the flap.The follow-up for 2-38 months (average, 19.3 months) revealed that all the flaps grew well with no recurrence of the sacralulcer. Conclusion The surgical treatment with the multi-island flap with shallow branches of the gluteus upper artery is a safe, highly-efficient and rapid approach to repair of the sacrum soft tissue defect and/or partial exposure of the bone. This kind of treatment has advantages of simpler procedures, better blood circulation of the flap, fewer complications, and higher success rates. 
