Even thought the composite graft has many advantage, its clinical use has been limited survival. Early vascularization from the recipient site is essential for the survival of the composite graft. We grafted 15mm-sized composite tissue on the rabbit ear. And the rabbit was treated with hyperaric oxygen or calcium antagonist. The survival area, survival rate, gross and histologic change were studied using the biopsy specimen which was taken on 2nd, 5th, 7th, and 14th postoperative day. The result are as follows; 1. The survival rate of hyperbaric oxygen treated group(89.7%) was significantly higher than that of the control group(65.3%).(p<0.001) 2. The survival rate of the calcium antagonist treated group(67.5%) was not significantly higher than the control group(65.3%).(P>0.1) 3. The color of the graf was monitored. At postoperative 24-48 hours, the color of the graft truned into pink-tined tone, and than changed into purple color at postoperative 4th-5th day. The color of the graft returned to nomal pinkish hue at 7th-10th postoperative day. We observed the same color change in each groups of survived composite graft. 4. The histologic finding of the hyperbaric oxygen treated group was compaired to those of the control or calcium antagonist treated group. The hyperbaric oxygen treated group showed less degeneration of epithelial cells and chondrocytes as well as less interstitial edema, but it showed increased chondroblasts and chondrocyte layers. In conclusion, we noticed that the hyperbaric oxygen treatment significantly increases the survival of the composite graft.

Industrial hand injury causes not only loss of hand function but also many socio-economic problem, because they are low socio-economic class, age of productivity and unemployed status due to functional disability of hand. Mainly, inexpert workers suffer from industrial hand injury (62%) probably due to absence of safe guard, safe-education and occupational training. Therefore, industrial hand injury may be diminished by preventive measure such as adequate safeguard, safe-education and occupational training. Statistical analysis was carried out retrospectively on 495 patients with industrial hand injury at Dept. of plastic and Reconstructive Surgery, Korea University College of Medicine, KURO hospital, from September 1986 to December 1988, and following items are studied. 1. Constitutions of industrial compartments and labors in Kuro and Youngdeungpo region. 2. Educational status of the patients. 3. Area distribution. 4. Monthly distribution. 5. Day of week distribution. 6. Onset time distribution. 7. Duration of occupation in the patients. 8. Causative factor. 9. Underlying factor. 10. Physical treatment and its duration. 11. postoperative grasping power. 12. Aesthetic result. We want this paper attribute to reduction of industrial hand injury.

다발성 K-강선을 이용한 수부 골절의 치료

홍성재,서형교,황종익,조상헌 대한수부외과학회 2013 대한수부외과학회지 Vol.18 No.3

Purpose: We reported results of percutaneous multiple K-wire fixation technique without passing through the joint in patients with a hand fracture. Methods: We evaluated a total of 116 cases in 94 patients who underwent percutaneous multiple K-wire fixation on dorsal cortex over a 10-year period between 2001 and 2010. The treatment outcomes were evaluated based on total active motion (TAM), as proposed by Widegrow. Results: Our clinical series of patients achieved good functional outcomes. Of total patients, 89% (84/94) had excellent TAM, 2% (2/94) did good TAM and 9% (8/94) did poor TAM. Postoperatively, our clinical series of patients had such a good compliance as to achieve a TAM of >181 when performing the early active movement. There were no notable postoperative complications during the follow- up period. Conclusion: Our results indicate that percutaneous multiple K-wire fixation technique without passing through the joint from normal bone density patients is effective in providing the rigid fixation. Thus, our patients could perform the early movement as promptly as possible and maintaining the full mobility of the rest of the hand. 목적: 정상 골밀도 소견을 보이는 환자군의 수부 골절 치료에 있어 다발성 K-강선을 이용하여 관절면의 통과 없이 고정한 결과를 보고하고자 한다. 대상 및 방법: 2001년부터 2010년까지 94명 116예의 수부골절 환자들을 대상으로 다발성 K-강선을 이용하여 배측 피질골에 고정을 시행하였으며 Widegrow가 제안한 총능동운동(total active motion, TAM)으로 수술 후 결과를 측정,평가하였다. 결과: 대부분의 환자에서 만족할 만한 결과를 보였다. 89% (84/94)에서 TAM ≥250。를 보였으며 2% (2/94)에서 181。<TAM<250。, 그리고 9% (8/94)에서 TAM <180。의 결과를 보였다. 견고한 고정 후 조기운동을 실시한 환자군에서TAM >181。의 좋은 결과를 얻었다. 추적기간 동안 합병증은 발생하지 않았다. 결론: 정상 골밀도 소견을 보이는 환자의 수부 골절 치료에 있어 다발성 K-강선을 이용하여 관절면의 관통없이 골절편을 견고하게 고정한다면 조기에 능동 및 수동운동을 시행할 수 있으며 이것은 수부의 빠른 기능 회복에 도움을 줄 것으로 생각된다.

Purpose: The recent advances in microsurgical techniques and their refinement over the past decade have greatly expanded the indications for digital replantations and have enabled us to salvage severed fingers more often. Many studies have reported greater than 80% viability rates in replantation surgery with functional results. However, replantation of multi-level amputations still remain a challenging problem and the decision of whether or not to replant an amputated part is difficult even for an experienced reconstructive surgeon because the ultimate functional result is unpredictable. Methods: Between January of 2002 and May of 2008,we treated 10 multi-level amputated digits of 7 patients. After brachial plexus block, meticulous replantation procedure was performed under microscopic magnification. Postoperatively, hand elevation, heat lamp, drug therapy and hyperbaric oxygen therapy were applied with careful observation of digital circulation. Early rehabilitation protocol was performed for functional improvement. Results: Among the 19 amputated segments of 10digits, 16 segments survived completely without any complications. Overall survival rate was 84%. Complete necrosis of one finger tip segment and partial necrosis of two distal amputated segments developed and subsequent surgical interventions such as groin flap, local advancement flap and skin graft were performed. The overall result was functionally and aesthetically satisfactory. Conclusion: We experienced successful replantations of multi-level amputated digits. When we encounter a multi-level amputation, the key question is whether or not it is a contraindication to replantation. Despite the demand for skillful microsurgical technique and longer operative time, the authors’ results prove it is worth attempting replantations in multi-level amputation because of the superiority in aesthetic and functional results.

요골 동맥 표재 수장 분지 감각 유리 피판술을 이용한 다발성 수지 첨부 결손의 재건

Purpose: The reconstruction of posttraumatic fingertip defects requires adequate soft tissue coverage, sensibility and minimal donor site morbidity. Reconstruction is more difficult in the case of multiple fingertip defects. The purpose of this study was to report the results of reconstruction of multiple fingertip defects using the innervated radial artery super-ficial palmar branch perforator flap (iRASP). Methods: We performed 19 cases of the iRASP for the reconstruction of multiple fingertip defects. The surgery was per-formed in two stages. In the first stage, defects were covered with the iRASP. In the second stage, the flap was divided 2-3 weeks after the first operation. Results: All flaps survived. At the last follow-up, static two-point discrimination was measured. A mean of 7.6 mm (6-9 mm) was measured on the affected side and 3.6 mm (2-5 mm) on the contralateral side. The sensory examination was performed at a mean 6.8 months (4-11 months) after surgery. Postoperatively, some patients complained of pain in the donor scars, but most of them disappeared after six months. Debulking surgery was not needed to improve the contours.Conclusion: We reconstructed multiple fingertip defects using the iRASP, and obtained satisfactory functional and cos-metic results. Four fingertip defects could be reconstructed with one flap and with satisfactory sensory recovery. There-fore, the iRASP is considered an appropriate treatment for reconstruction of multiple fingertip defects. 목적: 수지 첨부 손상의 재건 시 적절한 연부 조직의 피복, 감각, 공여부 이환율의 최소화 등을 고려해야 한다. 이러한 점을 고려하면 다수의 수지 첨부 손상 시에는 적용할 수 있는 방법이 제한적이다. 이에 저자들은 둘 이상의 수지에서 피부 및 연부 조직의 결손이 발생했을 경우 요골 동맥 표재 수장 분지 감각 유리 피판술(the innervated ra-dial artery superficial palmar branch perforator flap, iRASP)을 이용해 결손 부위를 재건한 결과를 분석하고 이를 보고하고자 한다.방법: 둘 이상의 수지 첨부 손상이 발생한 19예의 경우에서 iRASP를 시행하였다. 수술은 2단계로 시행하였으며, 첫 번째 단계에서는 손상 부위를 iRASP를 이용하여 피복하였고 2-3주 뒤 피판을 각각의 수지로 분리하였다.결과: 모든 예에서 피판은 생존하였다. 마지막 추시 시 정적 이점 식별력(static two-point discrimination)을 측정하였으며 건측은 평균 3.6 mm (2-5 mm)로 측정되었고, 환측은 신경 문합을 한 피판의 경우 7.6 mm (6-9 mm)로 측정되었다. 감각 검사 시점은 수술 후 평균 6.8개월(4-11개월)이었다. 수술 후 공여부 반흔의 통증을 호소하는 환자들이 있었으나 대부분 사라졌다. 모양의 개선을 위해 축소 수술(debulking surgery)이 필요한 경우는 없었다.결론: 다발성 수지 첨부 손상 시 iRASP를 이용하여 재건함으로써 기능적, 미용적으로 만족스러운 결과를 얻을 수 있었다. 네 개의 수지 첨부 손상 시에도 한 개의 피판으로 결손 부위의 재건이 가능하였으며 감각 회복 역시 만족스러웠다. 따라서 iRASP는 다수의 수지 첨부 손상 시 재건을 위한 적절한 치료 방법으로 생각된다.
