To evaluate the clinical application and surgical efficacy of the different extended LD flaps for large wounds in the extremities.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>From January 2004 to December 2018, 72 consecutive patients who received extended LD flaps were retrospectively analyzed. Patients' ages ranged from 2 to 68\u2009years with 37 males and 35 females. All wounds were extensive in either the upper or lower limbs, while the skin defect area ranged from 18 cm\u2009\u00d7\u200910 cm to 37\u2009cm\u2009\u00d7\u200921 cm. Forty\u2010one wounds were located in the calf, 18 in the foot and ankle, six in the shoulder and upper arm, four in the thigh, and three at the knee joint. Twenty\u2010eight patients had fractures, and six of these patients with segmental bone defects (ranging in size from 3 to 7 cm) required secondary orthopaedic procedures. Single\u2010 and double\u2010wing extended LD flaps were designed and harvested according to the shape of the wounds.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The flaps received consisted of 64 single\u2010wing and eight double\u2010wing extended LD flaps, and the mean flap harvest time was 56.2 min. The donor sites were closed primarily for all patients. Additional subcutaneous veins were anastomosed to the recipient's vessels in 14 patients. The venous crisis was noticed on the first postoperative day in four cases. Two flaps were salvaged after emergency re\u2010exploration, and another two patients' flaps were necrosed. In these two patients, lower limb amputation and extended LD flap on the other side were used, respectively, for the final treatment. The wounds healed well, providing reliable soft tissue coverage and good contour in the reconstructed areas. Six patients had segmental bone defects that required secondary orthopaedic procedures, two patients were repaired with vascularized iliac crest bone grafts, and another four patients were reconstructed by the Ilizarov technique. All the patients' bone defects achieved union and most patients achieved good functional recovery at the recipient site. The mean follow\u2010up was 15.7\u2009months (range, 10\u201356\u2009months). No significant donor site morbidities limiting patients' daily activities occurred during the follow\u2010up. Eight patients developed a donor site hypertrophic scar, three patients on the back, and five on the anterolateral thigh.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Single\u2010 and double\u2010wing extended LD flaps are simple and reliable methods for large skin and soft tissue
