Purpose: Perforator flap-using ischial sore reconstruction is performed in a prone position. But after the surgery, recurrence frequently occurs in a sitting position. In this sense, we introduce modified flap insetting method which closely resembles patient's sitting position to lessen the flap tension surgically. Materials and Methods: Authors tried to check a skin tension difference between prone position and sitting position in normal people group and to find out the importance of performing flap insetting in hip flexion position. Healthy volunteers were collected (n=20) and designed the same length of 4 divided sections around the ischium. Lengths of each section were measured when hip joint was flexed to 90 degree and when both hip and knee joints were flexed to 90 degree and the statistical evaluation was performed. Twenty cases with ischial sore underwent reconstructive surgery using perforator flap under hip flexion position and followed-up for any recurrences. Results: There was a meaningful difference between the joint flexed skin length and that of the neutral position. Flap showed sufficient thickness over 12 months. Conclusion: It seems that recurrence could be reduced when the reconstructed flap could sufficiently cover in a sitting position regarding its significant length difference in normal people group.
Purpose: Skin grafting is used for the transfer of cutaneous tissue from one site of the body to another. To improve graft survival, close contact between the graft and the wound bed is essential for vessels to grow across the gap. Here, we introduce an easy and efficient dressing method to improve graft survival. Materials and Methods: A retrospective chart review was performed to identify patients who underwent split thickness skin graft and negative pressure wound therapy (NPWT) or conventional treatment between January 2007 and April 2015. Overall, 25 consecutive patients were included in the NPWT group and 49 were included in the conventional dressing group to compare the outcome of the procedure. The data were obtained from medical records, including age, sex, cause of the skin defect, size of graft, time for healing, wound preparation time, and complications. Results: Of the NPWT group, the average wound size was $147.04{\pm}146.74cm^2$ (range, $9{\sim}900cm^2$). With the exception of one patient, all wounds healed without the need for further procedure. The average duration of time required for the NPWT group, which was defined as removal of stitches (or staples) and no need for additional active dressing, was $6.4{\pm}1.97days$ (range, 5~15 days). The average time for the conventional dressing group was $10.78{\pm}2.38days$ (range, 5~15 days). Conclusion: NPWT can be used to cover regions in which wound healing does not occur fully or when neither tie-over nor compressive dressings are applicable. This treatment also reduced wound healing time and allowed earlier patient mobilization and hospital discharge.

Purpose: Soft tissue defects in the lumbosacral area can be challenging to treat, and various methods to accomplish this have been proposed, including the use of perforator flaps. Herein, we present our experience with superior gluteal artery perforator (SGAP) and inferior gluteal artery perforator (IGAP) flaps for the reconstruction of lumbosacral defects. Materials and Methods: From March 2013 to July 2016, 28 cases (27 patients) of lumbosacral defects were treated by reconstruction with SGAP or IGAP flaps. The defects were caused by pressure sores (21 cases), burns (3 cases), tumor resection (2 cases), scars (1 case), or foreign body infection (1 case). Reliable perforators around the defect were found using Doppler ultrasound. The perforator flaps were elevated with a pulsatile perforator and rotated to cover the defects. Results: Twenty-three SGAP and 5 IGAP flap reconstructions were performed. The mean flap size was $9.2{\times}6.1cm^2$ (range, $5{\times}3cm^2$ to $16{\times}10cm^2$). Donor sites were closed by primary closure. Partial flap necrosis occurred in two cases, and minor complications of wound dehiscence occurred in 3 cases, which were healed by primary closure. The mean follow-up period was 4.4 months (range, 1~24 months). Conclusion: Gluteal-based perforator flaps can be safely harvested due to pliability and reliable vascularity in the gluteal area, reducing donor site morbidity without sacrificing the underlying muscles. Thus, these flaps are useful options for the reconstruction of lumbosacral defects.

This study was designed to introduce the cross-leg free flap only for vein anastomosis as an alternative salvage method for the reconstruction of severe soft tissue defects in vascular-compromised lower extremities. Four cross-leg free flap reconstructions were performed using the latissimus dorsi muscle to reconstruct soft tissue defects in the lower extremity. The recipient artery was confined to the ipsilateral side and the venous anastomosis was carried out in the contralateral side. Both legs were immobilized together with an external fixator. All patients were males, and had a mean age of 31 years. The mean time of pedicle division was 8.8 days range of 7 to 10 days. The mean size of the flap was 186.5 cm2. All flaps survived after pedicle division without venous congestion. There was no complication in joint stiffness, nor donor site morbidity except for a linear scar. The cross-leg free flap only for vein anastomosis is a refinement of a salvage procedure used for the reconstruction of severe soft tissue defects in vascular-compromised lower extremities.

Because traumatic tissue damage on hands and feet often lead to loss of function, permanent deformity, prompt and adequate reconstruction is essential. For children, future growth, as well as function and esthetics, must be taken into account. Several techniques have been employed to reconstruct hand and foot dorsum defects of children. However, skin graft and muscle free flap with skin graft cannot prevent contracture and will interfere with normal growth. Fasciocutaneous free flap reduces contracture and enables early physical therapy, decreasing the need for additional surgical intervention. Parascapular flap is particularly suitable because it has reliable pedicle and is relatively thin. There is little functional loss in the donor site, and also simultaneous extensor tendon reconstruction of hand and foot is possible. The disadvantage of this technique is that postoperative defatting is needed to adjust volume. Our department has achieved satisfactory results using this approach, and would like to report 13 cases of hand and foot reconstruction using parascapular flap in patients under the age of 15 (from March, 1998 to May, 2003).

Purpose: The purpose of this study was to present the clinical analysis of the results and our experience of the replantation surgery of the great toe. Materials and Methods: Between March 1995 and December 2002, twelve great toes, amputated from the distal phalanx to proximal phalanx were replanted. The complete types were 5 cases and incomplete types were 7 cases. The guillotine injuries were 4 cases and the crushing injuries were 8 cases. Results: Replantation in eleven out of the twelve amputations survived. The cases of revision were 3 cases due to venous thrombosis. Patients were followed up for a mean period of 2.2 years. The mean total active motion of the first MTP joint was $80^{\circ}$. The fusion of IP joint was carried in 7 cases due to the amputation of the IP joint level. The shortening of the replanted great toes was present, with average 0.9cm. The two point discrimination was 7-8mm except 2 cases with loss of nerve. Conclusion: Although replantation of the great toe remains to be controversial, replantation of the great toe should be considered in well-motivated patients because successful replantation regains an important component of the foot and good functional, cosmetic results.
Purpose: To cover the exposed tendons and bones after trauma and cure the concomitant osteomyelitis in the lower extremities, gracilis muscle free flaps are frequently preferred. 32 cases of gracilis muscle free flap we had done were analysed according to the indications, specification of flap length and width, pedicle length, vessels used in the anastomosis and final healing after at least over 1 year follow up. Materials and methods: From August 1995 through November 2002, we have performed 32 cases of gracilis muscle free flap transplantation with the general microsurgical procedures in the lower extremities. Open fracture of the middle and distal tibia were 12, exposed heel 6, crushing injury in the foot 5 cases, open fracture of the ankle 4, chronic osteomyelitis of the tibia 3 and osteomyelitis of the tarsal bones 2. Tailored flap length were ranged from 16 cm to 4 cm, width were from 5cm to 4cm. Pedicle length averaged around 4 cm. Anastomosis of one artery and two veins in both of donor and recipient were performed in 17 cases and one artery and one vein in 15 cases. Results: All flaps were survived, except 2 cases. Final flap healing was satisfactory to both of the patients and microsurgeon. Conclusion: Gracilis muscle free flaps are frequently chosen to cover the exposed components and cure the osteomyelitis in the lower extremities.

Advances in microvascular techniques and refinements in microsurgical tissue transfers have enabled surgeons to combine different tissue components and reconstruction into a single-stage operation in extensive or composite defect following injury. Some problems and consideration for extensive or composite defects are form, shape, function, and dimension of the defect sites. Therefore combination of two or more flaps is required to reconstruct extensive or composite defect. This paper presents our clinical experience of four cases of combined free flaps with or without sequential microanastomosis in reconstruction of upper extremity based on peroneal flowthrough, thoracodorsal, and dorsalis pedis vascular system. Satisfactory results were obtained without flap loss and complications. The free flaps were combined in th following fashion; two cases by bridge fashion, one by chimeric microanastomosis and one by simple chimeric fashion. The median follow-up time on all patients was 21.7 months. Donor site morbidity was minimal. Extensive soft tissue or composite defects can be effectively covered by various combined flaps. Even though the risk for complication exists, the options of combination with or without sequential microanastomosis can add a functional or sensory dimension to reconstruction of complex wounds.
Introduction: To cover the exposed tendons and bones in the foot and hand which need coverage and abundant vascular flow, lateral arm flaps were transferred. Lateral arm flap is a thin and innervated fasciocutaneous flap with a lower lateral cutaneous nerve and posterior radial collateral artery. Materials and methods: From October 1992 through September 2003, we have performed 5 lateral arm flaps for reconstruction of the exposed achilles tendons in 2 cases and the exposed forearm extensors, 2nd to 5th metacarpal bones and scaphoid each 1 case. The causes were traffic accident in 2 cases and machinary injury in 3 cases. Age range was between 31 to 74 (average 50) and all male except 1. Posterior lateral collateral artery and venae comitantes were anastomosed by end to end in 3 cases and vena comitante in 2 cases. Lower lateral cutaneous nerve was anastomosed with a branch of superficial radial nerve in 2 cases. Results: The results were evaluated by survival of the flap, sensory discrimination, cosmesis and comfort in the activities of the daily living. All flaps were survived. Sensory recovery was graded as deep cutaneous pain sensibility in 2 cases. Cosmesis was moderately satisfied and comfort was good except 1 as moderate. Postoperative defatting procedure was done in 1 case and skin abrasion was occurred in 1 case. Conclusion: Lateral arm flap was suitable for coverage of the exposed achilles tendons and exposed forearm extensors, metacarpals and scaphoid in the wrist.
Purpose: We reconstructed the skin defect of hands exposing tendons and/or bone with distally based ulnar artery flap and report our cases. Materials and Methods: Between March 2005 and September 2007, 6 cases of skin defect were reconstructed with distally based ulnar artery flap. Defect site were 5 cases of hand dorsal side and 1 case of hand volar side. The average defect size was $3{\times}3\;cm^2$. There were 4 men and 2 women and mean age was 55.5 years. We evaluated the viability of flap, postoperaive complication, healing time, patient's satisfaction. Results: There was no flap failure in 6 cases. But 1 case with recurrent discharge was healed with several times adequate debridement and delayed suture. 1 case with flap edema which might be due to venous congestion was healed with hand elevation and use of low molecular weight heparin. Mean time to heal the skin defect was 4 weeks. No infection and recurrence was found in follow up period. Cosmetic results as judged by patients were that 3 cases are good and 3 cases are fair. Conclusion: Distally based ulnar artery flap is good treatment method among the numerous methods in the cases of skin defect, with soft tissue exposed, which is not covered with debridment and skin graft. Distally based ulnar artery flap is useful method for the skin defect of hands because it is simple procedure, has constant blood supply and relatively good cosmetic effect.
