Arthrodesis of the ankle joint is inevitable in the cases of severe arthrosis or defective bony structures around ankle joint. There have been many kinds of arthrodesis methods were introduced. In cases with failed athrodesis with previous arthrodesis surgery and neuropathic joints have difficulty to achieve fusion of joint with conventional methods. Authors underwent four cases of ankle fusion with vascularized fibular graft from 1997 in the cases of three failed fusions and one diabetic neuropatic joint. Two of four performed free vascularized fibular transplantation from contralateral side leg with microvascular anastomosis, two of four performed with pedicled fibular transposition to the ankle joint in same side leg. Three of four cases achieved arthrodesis average 9.2 months after surgery, one case was failed due to vascular thrombosis of the anastomosed site in diabetic neuropathic condition. The result of this technique revealed 75%(three of four) success rate and longer bone union time required. However, in these cases had no recommendable options with conventional bone graft and additional ankle joint fusions procedure because of poor bone quality and defect of distal tibia and talus portions. Free vascualrized fibular transfer to the failed athrodesis of ankle joint is one of the effective alternative methods in failed ankle fusion cases, especially the quality of the bone around previous fusion site is poor.

Purpose: To report the results and the efficacy of the sensory bearing scapular free flap which is known as non-sensible flap. Materials and Methods: Authors underwent 24 cases of sensory bearing scapular free flap to the hands and feet from March 1995 to November 2002. average follow-up period was six year three months. The used flaps were a ordinary scapular flap in fifteen cases, and a parascapular flap in nine. Sensibility of the flaps were checked every one month. Actual sensory evaluation was mostly depends on objective feeling of the patients. Two point discrimination test was performed in all cases. Results: 23 flaps had good skin circulation after microvascular anastomosis among 24. Objective deep touch sensation were observed about three months later after the operation in three cases, between three and six months in nine. In three case whose results were excellent than others, two point discrimination was 2.7 cm at last follow-up. Most of the sensory recovery is confined in deep touch, temperature and light touch sensation was recovered limitedly in 3 cases during our follow-up period. Conclusion: Authors can propose that sensory bearing free scapular flap was considered as one of useful methods for the reconstruction to hand with soft tissue defect and mutilating hand.

Radial forearm flap is one of the most useful skin flap in hand reconstructuion with distally based reverse pedicled or free vascularized fashion. Athors modified that flap into reverse pedicled and free vascularized flap which has advantages of both methods. The modification composed with harvesting flap on recipient side distal forearm just as free flap, than apply it as reverse distal pedicled flap fashion with microvascular anastomosis with distal vascular stump of donor radial vessels. We underwent this method in 5 cases in finger reconstruction from 1996, all of the cases had sucessful results. The advantages of this method are: 1. Thin flap which is compatible to finger skin can harvest from distal forearm with very long vascular pedicle that can be passed under the subcutaneous tunnel which avoid additional skin incisions on the hand. 2. The vessels of donor site and recipient site are same vessel in effected side of forearm, which can preserve contralateral side forearm and hand keep intact. 3. The flap can cover the defects on distal portion of the fingers which is difficult in conventional reversed radial forearm pedicled flap because of limited mobilization of flap due to limitation of pedicle length reach to tip of the fingers.

The ability for tissue transfer based on microvascular anastomosis has created a revolution in microsurgical free tissue transplantation. The advantages of cutaneous flaps are that they are soft, durable and provide a good cosmetic reconstruction and muscle flaps have a more vigorous blood supply and a longer, larger vascular pedicle than cutaneous flaps. From June 1992 through May 1997, 68 patients had received reconstructive microsurgery in the lower extremity at Department of Orthopedic Surgery, Chonbuk National University Hospital. The results were as follows. 1. The age distribution was from 15 years of age to 67 and male were 59 cases and female 9 cases. 2. The most common cause was traffic accident(54 cases, 79.4%) and followed chronic osteomyelitis(9 cases, 13.2%), industrial accident(3 cases, 4.4%), burn(1 case, 1.5%) and farm injury(1 case, 1.5%). 3. Latissimus dorsi myocutaneous flap were 25 cases(36.8%), rectus abdominis muscle flap 21 cases(30.9%), gracilis muscle flap 10 cases(14.7%), dorsalis pedis flap 9 cases(13.2%), groin 2(2.9%) and vascularized iliac osteocutaneous flap 1(1.5%). 4. 61 cases(89.7%) of 68 cases were survived and the exposed vital tissues and bones were covered and revealed good cosmetic results.

Microsurgery is a precise surgical skill that requires an extensive training period and the supervision of expert instructors. The classical training schemes in microsurgery have started with multiday experimental courses on the rat model. These courses have offered a low threat supervised high fidelity laboratory setting in which students can steadily and rapidly progress. This simulated environment allows students to make and recognise mistakes in microsurgery techniques and thus shifts any related risks of the early training period from the operating room to the lab. To achieve a high level of skill acquisition before beginning clinical practice, students are trained on a comprehensive set of exercises the rat model can uniquely provide, with progressive complexity as competency improves. This paper presents the utility of the classical rat model in three of the earliest microsurgery training centres and the new prospects that this versatile and expansive training model offers.

Purpose: The repair of complex chest wall defects presents a challenging problem for the reconstructive surgeon. In particular, a free flap is often required when the defect is large, in which case suitable recipient vessels must be found to insure revascularization. The authors report a case of persistent bronchopleural - cutaneous fistula developed after undergoing lobectomy for lung cancer. Methods: The defect area was repaired using a free vertical rectus abdominis muscle flap revascularized by microvascular anastomosis to the 6th intercostal pedicle. The flap obliterated the right chest cavity, closed the site of empyema drainage, and aided healing of a bronchopleural - cutaneous fistula. Results: The patient has remained healed for 14 months without any postoperative complications and recurrent infection or fistula. Conclusion: We suggest that a rectus abdominis musculocutaneus free flap and intercostal pedicle as a recipient could be a useful method for repair of chest defects.

A fibrin adhesive have been widely used in oral and maxillofacial surgery for microvascular anastomosis, autogenous chip bone grafts, many kinds of soft tissue surgery (vestibuloplasty, bleeding control after extraction, primary healing by covering of suture of a gum after the extirpation of large cysts). There are two principal components in adhesive systems biologically: lyophilized human fibrinogen and bovine thrombin. The fibrinogen component contains coagulation factor XIII and enhance the initial wound healing, which polymerizes soluble fibrin monomers into an insoluble clot. The thrombin is dissolved in a solution of calcium chloride to provide the second component. We applied fibrin adhesive, Beriplast (Behring, Behringwerke AG, D-3350, Marburg, FRD), to 4 patients for fixation of free skin grafting donors who had facial scar around eye, nose, mouth corner which received from accidents, or burn. We have experienced initial accelerated graft fixation between donor and recipient sites with no additional fixation. And It's made easy bleeding control and easy manipulation during operation. But two cases showed partial hypertrophic scar engrowth in above 3 months follow up, but no significant. Histopathological reviews in general were showed similar scar findings such as abundant collagen bundles in H&E, M/T stain, but slight positive signs in elastic and collagen antibody immunopathologic findings in hypertrophic scar cases.

Purpose: Epidural abscesses and subdural empyemas after craniotomy are uncommon, potentially lethal, complications of neurosurgery. Patients with these complications may be difficult to manage and dural reconstruction in these patients are challenging. Methods: A 28 - year - old female patient showed recurrent intracranial infection after craniotomy for evacuation of a arachnoid cyst and subdural hematoma. Despite prolonged systemic antibiotic administration and a debridement of the subdural space, infection persisted, as evidenced by persistent fever, an elevated WBC count, CSF leakage, low CSF glucose level, and purulent wound discharge. The authors removed the previously applied lyophilized dura and transferred free omental flap to reconstruct the dura, obliterate the cyst and cover the cerebral hemisphere in the craniotomy defect. Microvascular anastomosis was between gastroepiploic and superficial temporal vessels. Results: The postoperative course was uneventful and flap survival was excellent. The infection - resistant omental tissue allowed sufficient blood circulation and dead space control. The patient was discharged 1 month after surgery and wound discharge or recurrence was absent during 13 months of follow up periods. Conclusion: The use of vascularized free omentum proved useful in cases of intractable cranial wound infection and cerebrospinal fluid leakages.

Despite of technical advances in surgery & other therapeutic modalities five-year survival rates in patients with carcinoma of hypopharynx have remained low. Many techniques have been used to create a structure capable of allowing the passage of food and fluids in an attempt to maintain the anatomy and physiology of the upper digestive system. The development of microsurgical techniques and the concept of mucocutaneous unit has brought about important changes in the reconstruction of cervical esophagus following tumor resection. The one-stage procedure using microvascular anastomosis of free jejunal graft provides physiologic reconstruction of cervical esophagus and has a low morbidity rate as well as a short recuperation time. With free jejunal graft, there is marked improvement in the quality of life and numerous advantages over the previous methods of reconstruction. Reconstruction of esophageal defect after resection of carcinomas of the hypopharynx, and cervical esophagus has traditionally been carried out with deltopectoral, or musculocutaneous skin-lined flaps. A second approach is to reconstruct the defect with the colon or stomach. A more ideal mettled is to repair these defects with mucosa-lined flaps. The authors experienced 35 cases of reconstruction of cervical esophagus after resection of carcinoma of the hypopharynx with free jejunal autograft and one case of secondary repair with radial forearm free flap after failure of initial free Jejunal autograft. Postoperative results were satisfactory in most patients and two patients expired in 8 days postoperatively because of carotid blow out by chronic inflammation.
