The traditionally useful coverage methods of the wrist and hand soft tissue defect are the chinese forearm flap, the ulnar forearm flap. But, this flaps are inevitably sacrifice major vessel to the hand. Advantages of the posterior interosseous artery island flap(PIA Flap) is no need to sacrifice blood supply to the hand and supply relatively large thin, good quality flap and more cosmetic than other forearm flaps. But, it is difficult to dissect and raise because of deep seat, close relation with the posterior interosseous nerve and anatomic variation. Authors evaluated 8 cases of 7 patients in the department of orthopaedic surgery, college of medicine, Hallym University from January, 1993 to December, 1995. The results are as follows: 1. The satisfactory coverage was achieved 7 cases and 1 case failed because of anatomic variation. 2 The pedicle length is average 9cm and the flap size is variable from 3cm by 4cm to 5cm by 8cm. 3. The donor site defect was repaired by direct closure in 5 cases, remained 3 cases combined with skin graft. From our experience we conclude that the PIA flap is one of the useful coverage methods of the wrist and hand soft tissue defect.
Large soft tissue defect of the ankle and foot can present a difficult reconstructive problem to the surgeon. Local musculocutaneous, local fasciocutaneous or free flap is usually the first choice for providing soft tissue coverage. However, in certain situations, local flaps from the same leg and free flap may not be suitable. These include extensive soft tissue injury, where no suitable recipient vessels can be found, previous local fasciocutaneous flap or free flap failure. In such cases, we have utilized the septocutaneous(fasciocutaneous) branch flap of posterior tibial artery from the opposite healthy limb. We present 5 cases of cross leg flaps, which have been modernized with current understanding of vascular anatomy and current fixation technology. All cross leg flaps were based on the axial blood supply of the fasciocutanous branch of the posterior tibial artery. Cross-clamping with bowel clamp was used to create intermittent periods of ischemia. Adjacent lower extremity joints were exercised during the periods of attachment. The results have been quite encouraging. We conclude that the cross leg flap using septocutaneous flap and cast immobilization can be successfully and expeditiously used to cover defects of the ante and foot.
The extensor digitorum brevis (EDB) muscle island flap is a reliable, safe method for coverage of foot and ankle. There are many variation in approach such as curvilinear, zigzag, L-shaped or vertical longitudinal incision for exposure of the EDB muscle. These approaches use only single incision excluding the distal incision for exposure of the distal tendon. Since dorsalis pedis artery vascular bundle and sinus tarsi branch of the lateral tarsal artery both requires careful dissection, single incision alone may cause not only difficulty in exposure but also skin sloughing at donor site. So we tried to modify the approach into two parallel longitudinal incision, one for dorsalis pedis vascular bundle and the other for sinus tarsi branch exposure. The author treated 9 patient with EDB muscle flap. We used single incision in six patients, and two parallel incision in three patients. All the flap survived. In two parallel incision group, dissection was more easy and rapid. So we would like to suggest that two parallel longitudinal incision approach is better method than the single incision technique for exposure of the EDB muscle flap.
Purpose: Disaster as traffic accident, industrial disaster, high voltage electrical bum and flame burn of extremity have a destructive effect because of the involvement of deep structure. Generally, such injury may result in decreased function or loss of limb. In this study the successful use of the combined scapular/parascapular flap as microsurgical transfer to cover extensive defect of electrical and flame bum is reported. Material and Method: Between January 2000 and June 2001, the combined scapular and parascapular flap was used for the coverage of soft tissue defect for 7 patients were admitted to our department with high voltage electrical bum and flame burn. The recipient site were the wrist joint in 2 cases, the forearm in 1 case, the ankle joint in 1 case, the foot dorsum in 1 case, the heel in 1 case. Result: Flap survival was complete in all patients. The result of flap coverage for these deep wound was successful. Conclusion: The advantages of scapular/parascapular combined flap were coverage of the large defect, easy shaping of the flap to fit the required three dimensional configuration around the joint, non hair bearing skin of uniform thickness, minimal donor site morbidity.

Introduction: The hand and wrist are particularly susceptible to electrical burn. Skin defect with damage or exposure of underlying vital structure requires coverage by skin flap especially in case of the need for late reconstruction. We are reporting 4 cases of electrical burned hand treated by posterior tibial arterial free flap. The commonly used skin flaps such as scapular flap or groin flap are too bulky so that they are not satisfactory in function and cosmetic appearance. So we tried to cover them with a more thin skin flap. Materials and Method: From January 2002 to June 2003, four cases of hand and wrist electrical burn were covered using posterior tibial arterial free flap. All the cases were due to high voltage electrical burn. Age ranged from 31 years to 38 years old and all the cases were male patients. Recipient sites were 2 wrist, one thenar area and one knuckle of 2.3rd MP joint. Additional procedures were flexor tenolysis (simultaneous), FPL tenolysis and digital nerve graft (later) and extensor tendon reconstruction (later). Result: All the flap have survived totally without any complication including circulatory concern about the donar foot. Posterior tibail arterial free flap was so thin that debulking procedure was not required. Conclusion: For skin coverage of the hand & wrist region, posterior tibial arterial free flap have many advantages such as reliable anatomy, easy dissection and easy anastmosis with radial or ulnar artery and possibility of sensory flap. The most helpful advantage for hand coverage is its thinness. So we think this flap is one of the very useful armamentarium for reconstructive hand surgery.
Introduction: The purpose of this study is to evaluate the necessity of distant pedicled flap in the treatment of soft tissue defects in the hand. Materials and Methods: Distant pedicled flap was performed in the 25 hands of 25 patients from 2000 to 2004. There were 20 males and 5 females and mean age was 34 years. The surgery was done for electrical burns in 13 patients, flame burns in 8 patients and crushing injuies in 4 patients. Results: We have performed 25 distant pedicled flaps for the coverage of soft tissue defects in the hands when local and free flaps were unavailable. Soft tissue coverages by distant pedicled flap were completely successful in all the 25 hands. No complication such as total flap loss, marginal flap loss and infection occurred. Conclusion: Distant pedicled flaps were very useful alternative method in the treatment of soft tissue defect in the hand.
Free vascularized tissue transfer to preserve upper extremity amputation level is uncommon but very useful procedure. To cover the below-elbow amputee stump and restore the function of the elbow, we have used a free flap as a spare part concept from the contralateral hand which was so severely damaged that amputation was inevitable.
Purpose: To describe the surgical treatment of the complex dorsal metacarpophalangeal dislocations and its results,emphasizing on the modified volar approach with A1 pulley release. Materials and Methods: We experienced 6 cases of dorsal dislocation of the metacarpophalangeal joint. We performed open reduction with the modified volar approach described by Eaton and Dray. Postoperatively posteroanterior and lateral radiographs of the index finger metacarpophalangeal joint and metacarpophalangeal joint range of motion was followed. Results: One case with a large osteochondral fracture was operated with volar and doral approach both. Overall end results were good without any significant restriction of motion and stability of the fingers. Conclusion: Modified volar approach with A1 pulley release is an excellent method for complex dorsal metacarpophalangeal dislocations without osteochondral fracture. 목적: 수부 중수 수지 관절의 후방 복잡 탈구에 대한 변형 전방 접근법에 의한 관혈적 정복술의 우수성을 알아보고 그 결과를 기술하고자 하였다. 대상 및 방법: 총 6예의 수부 중수 수지 관절의 탈구 환자를 대상으로 Eaton과 Dray의 변형 전방 접근법에 의한 관혈적 정복을 시행하였다. 술 후 추시에서 단순방사선촬영상 전 후면 및 측면에서 관절면의 정복 여부 및 능동적 관절 운동 범위를 측정하였다. 결과: 전방 접근법만으로는 정복이 불가능하여 후방 접근법을 동시에 사용한 1예를포함한, 6예 모두 방사선 소견상 관절면의 일치 및 관절 운동 범위는 정상으로 회복되었으며, 특별한 합병증 없이 회복되었다. 결론: 관절 내 골절이 없는 수부 중수 수지 관절의 후방 탈구에서 변형 전방 접근법에의한 관혈적 정복은 안전하고 쉬우며 만족할 만한 결과를 얻을 수 있는 방법이다.
