This article portrays the authors' experience with a complex lower limb bone and soft tissue defect, following chronic osteomyelitis and pathological fracture, which was managed by the multidisciplinary orthoplastic team. The decision for functional amputation versus limb salvage was deemed necessary, enhanced by the principles of "spare parts" in reconstructive microsurgery. This case describes the successful use of the osteocutaneous distal tibia turn-up fillet flap that allowed "lowering the level of the amputation" from a through knee to a below-knee amputation (BKA) to preserve the knee joint function. We comprehensibly review reports of turn-up flaps which effectively lower the level of amputation, also applying "spare-parts" surgery principles and explore how these concepts refine complex orthoplastic approaches when limb salvage is not possible to enhance function. The osteocutaneous distal tibia turn-up fillet flap is a robust technique for modified BKA reconstructions that provides sufficient bone length to achieve a tough, sensate stump and functional knee joint.

조직확장술에 의해 확장된 토끼의 피부를 관찰하여, 확장의 정도에 따른 피부의 조직학적인 변화를 단계적으로 추적해 본 결과를 요약하면 다음과 같다. 1. 표피층의 전반적인 두께 변화는 미약하였으나, 확장초기에는 거의 변화가 없다가 과도한 확장시 얇아지는 경향을 보였다. 2. 진피층의 두께는 확장이 진행됨에 따라 점차 얇아졌으며, 진피층내의 교원섬유조직은 확장의 초기단계에서부터 현저히 증가되어 있었다. 3. 진치층내의 혈관의 분포정도는 확장이 진행됨에 따라 점차 증가하였다. 4. 피부부속기들은 6배정도의 과도한 확장상태에서도 광학현미경상 구조의 변화를 보이지 않았다. 5. 피부근층(panniculus carnosus)은 6배 정도의 과도한 확장상태에서도 구조적 변화나 두께의 변화를 보이지 않았다.

목적 : 전방 십자 인대 재건술시 동반된 반월상 연골의 파열에 대해 meniscus $arrow^{\circledR}$(BIONX, Tampere, Finland)를 이용한 봉합술의 치험예를 통하여 그 유용성에 대해 알아보고자 하였다. 재료 및 방법 : 1997년 5월부터 2000년 7월까지 전방십자인대 재건술과 함께 meniscus arrow를 이용하여 반월상 연골의 봉합술을 시행하고 추시가 가능하였던 17례를 대상으로 하였으며 추시 기간은 평균 18.5개월이었다. 손상 부위는 내측 12례, 외측 5례였고, 손상 형태는 전례에서 종 파열이었으며 red-rd 지역이 13례, red-white 지역이 4례였다. 술후 결과는 반월상 연골에 의한 증상(동통, 관절선 압통, 잠김, McMurray 검사)의 유무에 대해 알아보고 Marshall knee score를 이용하여 술전후 슬관절의 기능적 평가를 시행하였고 합병증에 대해서도 알아보았다. 결과 : 술후 2례에서 경도의 관절선 압통을 보였으나 관절 운동이나 체중 부하시 특별한 동통을 호소하지 않았으며 전례에서 잠김 증상이나 McMurray 검사는 음성이었다. 최종 추시점에서 Marshall knee scoring scale을 이용한 결과는 15례$(88\%)$에서 good 이상의 만족스러운 결과를 보였다. 합병증으로는 1례에서 술후 능동적 관절운동시 슬관절의 내측에 걸리는 느낌의 날카로운 통증을 호소하였으나 술후 6주에 소실되었다. 다른 1례에서 반월상 연골 밖으로 돌출된 arrow의 T-Head에 의한 대퇴골 연골 손상이 있었다. 결론 : 전방십자인대 재건술시 동반된 반월상 연골 손상, 특히 내측 반월상 연골의 후각부 파열에 대해 meniscus arrow를 이용한 봉합술도 하나의 치료방법이 될 수 있으나 연부조직 자극으로 인한 통증과 대퇴골 연골 손상이 발생될 수 있다는 것을 염두에 두어야할 것으로 생각된다.

Purpose: Microvascular free tissue transfer has become a reliable technique for the reconstruction of complex wounds. Occasionally, unexpected intraoperative thrombosis and/or spasm of recipient artery might be annoying problems even for the technically competent microvascular surgeons. If such problems are not treated properly, they will inevitably cause to flap failure. Methods: From January 2006 to February 2007, soft tissue reconstructions by free tissue transfers were performed on 21 patients having complex defects in the lower extremity. Although segmental revision and various pharmacologic agents were repeatedly applied, arterial occlusions were not managed in 6 cases. For removal of thrombi and release of spasm, Fogarty No. 2 or No. 3 catheters were inserted into the lumen to the proximal recipient artery. Its balloon was then inflated after passing through a resistant area. Next, the catheter was gently withdrawn backward. Results: After the Fogarty catheter was inserted two or three times, the pulsatile arterial flow was restored. When the catheter was inserted into the lumen, a feeling of resistance existed in a 5-10cm more proximal portion that could not be easily accessed from the vascular end. After the reestablishment of blood flow, successful anastomoses were achieved and immediate rethrombosis or spasm did not occur. No long-term sequelae associated with balloon trauma to the arterial wall were observed. Conclusion: The use of the Fogarty catheter can be an effective method in treating pedicle thrombosis and spasm. This is a very simple and rapid technique that offers microvascular surgeons another option to increase the success rate of microvascular anastomosis in free tissue transfers.

Rheumatoid arthritis is a long lasting autoimmune disorder that primarily affects joints, and patients with rheumatoid arthritis are predisposed to development of chronic skin ulcers. In addition, skin ulcers with rheumatoid arthritis tend to persist despite treatment because of sustained inflammation and poor healing capacity. Treatment of skin ulcers involves medications, wound coating agents, and surgical procedures including skin grafting, however, wound dressing or skin grafts are generally excluded because of excessive cost and time and poor intake rate. The dorsal metacarpal artery perforator (DMAP) flap, a vascular island flap for coverage of soft tissue defects on the fingers, provides promising results including matched quality and color. We experienced a case of DMAP flap for reconstruction of a rheumatoid ulcer, and a DMAP flap may be considered as a good faithful option for treatment of patients with rheumatoid ulcer.

Purpose : Loss of sensibility over the finger tip resents a grave deficit and is an indication for sensible soft tissue reconstruction. This paper was performed to assess the long term results obtained by nerovascular island flap. Material and Methods : We performed neurovascular island graft for defective sensibility of finger tip loss in 94 cases since 1979 to 2000. The recipient sites were the thumb pulp defect in 79 cases, the amputated thumb in 9 cases, the amputated index in 4 cases, and the velar aspect of interphalangeal joint of thumb in 2 cases. The donor flaps were obtained from the radial side of ring finger in 63 cases, the ulnar side of the ring finger in 21 cases, and the ulnar side of the middle finger in 10 cases. A mean follow-up period was 5.7 years. Results : The flap quality was well vascularized and survived in 89 cases. The two-point discrimination was average 8.7mm. Because of scar contracture, the range of motion of the donor finger was decreased 3.5% of the normal finger in the distal interphalangeal joint, 8,2% in the proximal interphalangeal joint. A phenomenon of double sensibility occurred in 66 cases. Conclusion : This technique was excellent both aesthetically and functionally as a reconstruction of the Loss of fingertip.

Purpose: The operative treatment for blow-out fracture involves restoration of intra-orbital soft tissue and bony structural integrity. There are several methods for reconstruction of inferior blow out fracture. We report reduction of inferior blow-out fracture with urinary balloon catheter in comparison with $Medpor^{(R)}$ using group to complication rate. Methods: A retrospective study was performed on 67 patients who underwent inferior orbital blow-out fracture reconstruction with $Medpor^{(R)}$ implant or urinary balloon catheter following between 2003 and 2006. Hospital records were reviewed especially for preoperative and postoperative enophthalmos, diplopia, extraocular muscle movement limitations, and hypoesthesia between $Medpor^{(R)}$ implant group and balloon catheter using group. Results: There was no significant statistical difference between both groups on incidence of postoperative complications of enophthalmos, diplopia, extraocular muscle movement limitations, and hypoesthesia. Postoperative infection, ectropion were absent in both groups.Conclusion: The use of urinary balloon catheter is simple, fast and inexpensive. Urinary balloon catheter is an alternative and reliable use for reduction of inferior orbital blow-out fracture.

Reconstruction following a resection of malignant oral cavity tumors is one of the most difficult problems in recent oral oncology. The radial forearm free flap (RFFF) is a thin, pliable soft tissue flap with large-caliber vessels for microvascular anastomosis. Its additional advantages include consistent flap vascular anatomy, acceptable donor site morbidity and the ability to perform simultaneous flap harvest with a tumor resection. For a better understanding of RFFF as a routine reconstructive procedure in oral and maxillofacial surgery, the constant anatomical findings must be learned and memorized by young doctors during the special curriculum periods for the Korean national board of oral and maxillofacial surgery. This review article discusses the anatomical basis of RFFF in the Korean language.

Recently, the anterolateral thigh(ALT) flap, based on the septocutaneous vessels or musculocutaneous perforators from the descending branch of the lateral circumflex femoral artery has gained popularity in head and neck soft-tissue reconstruction. It has some advantages in free-flap surgery with respect to the radial forearm free flap, such as low donor site morbidity, availability of different tissues with large amounts of skin, adaptability as a sensate or flow-through flap (with the possibility of harvesting a long pedicle with a suitable vessel diameter). Moreover, the thickness of the flap is adjustable until the subdermal fat level, allowing it to be used as a thin or ultrathin flap. This clinical cases are ALT free flap reconstructions without functional impairment of the donor limbs (transitory and permanent) based on anastomosis with superficial temporal arteries and veins in patient of huge resection defect on face, lip and tongue.
