Purpose: We reconstructed the thumb with groin flap combined with secondary heterodigital neurovascular island flap and report our 6 cases. Materials and Methods: Between March 2003 and August 2004, 6 degloving thumbs or amputation of thumbs were reconstructed with groin flap combined with secondary heterodigital neurovascular island flap. There ware 4 men and 2 women, and mean age was 42.2 years. The following parameters were evaluated. Results: Recipient thumb was no limitation of apposition. but flexion contracture of interphalangeal joint was about 10 degree in two cases. Average grip power were 80% and average pinch power were 70% that of the normal thumb. The two point discrimination was average 10.5 mm and double sensibility in 2 cases. 2 patients have cold intolerance. Neuroma formation was not made. Cosmetic results as judged by patients were that 4 cases are good and 2 cases are fair. Conclusion: If massive skin defect after degloving thumb or amputation of thumb are present, we consider the numerous methods for reconstruction of thumb. This surgical procedure is good methods because of it's pliability, sensation, satisfactory functional results but major disadvantage are the staged operation and cosmetic effect of the absence of thumb nail.

Objective : To study the factors relating to operative treatment for spinal metastasis in Thailand during 2005-2014 and to determine the hospital costs, mortality rate, and incidence of perioperative complication. Methods : Inpatient reimbursement data from 2005 to 2014 was reviewed from three national healthcare organizations, including the National Health Security Office, the Social Security Office, and the Comptroller General's Department. The search criteria were secondary malignant neoplasm of bone and bone marrow patients (International Classification of Diseases 10th revision, Thai modification codes [ICD 10-TM], C79.5 and C79.8) who underwent spinal surgical treatment (ICD 9th revision, clinical modification procedure with extension codes [ICD 9-CM], 03.0, 03.4, 03.09, and 81.0) during 2005-2014. Epidemiology, comorbidity, and perioperative complication were analyzed. Results : During the study period, the number of spinal metastasis patients who underwent operative treatment was significantly increased from 0.30 to 0.59 per 100000 (p<0.001). More males (56.14%) underwent surgical treatment for spinal metastasis than females. The most common age group was 45-64 (55.1%). The most common primary tumor sites were the unknown origin, lung, breast, prostate, and hepatocellular/bile duct. Interestingly, the proportion of hepatocellular/bile duct, breast, and lung cancer was significantly increased (p<0.001). The number of patients who had comorbidity or in-hospital complication significantly increased over time (p<0.01); however, the in-hospital mortality rate decreased. Conclusion : During the last decade, operative treatment for spinal metastasis increased in Thailand. The overall in-hospital complication rate increased; however, the in-hospital mortality rate decreased.

Objective : The efficacy of preoperative embolization for hypervascular metastatic spine disease (MSD) such as renal cell and thyroid cancers has been reported. However, the debate on the efficacy of preoperative embolization for non-hypervascular MSD still remains unsettled. The purpose of this study is to determine whether preoperative embolization for non-hypervascular MSD decreases perioperative blood loss. Methods : A total of 79 patients (36 cases of preoperative embolization and 43 cases of non-embolization) who underwent surgery for metastatic spine lesions were included. Representative hypervascular tumors such as renal cell and thyroid cancers were excluded. Intraoperative and perioperative estimated blood losses (EBL), total number of transfusion and calibrated EBL were recorded in the embolization and non-embolization groups. The differences in EBL were also compared along with the type of surgery. In addition, the incidence of Adamkiewicz artery and complications of embolization were assessed. Results : The average age of 50 males and 29 females was $57.6{\pm}13.5$ years. Lung (30), hepatocellular (14), gastrointestinal (nine) and others (26) were the primary cancers. The demographic data was not significantly different between the embolization and the non-embolization groups. There were no significant differences in intraoperative EBL, perioperative EBL, total transfusion and calibrated EBL between two groups. However, intraoperative EBL and total transfusion in patients with preoperative embolization were significantly lower than in non-embolization in the corpectomy group (1645.5 vs. 892.6 mL, p=0.017 for intraoperative EBL and 6.1 vs. 3.9, p=0.018 for number of transfusion). In addition, the presence of Adamkiewicz artery at the index level was noted in two patients. Disruption of this major feeder artery resulted in significant changes in intraoperative neuromonitoring. Conclusion : Preoperative embolization for non-hypervascular MSD did not reduce perioperative blood loss. However, the embolization significantly reduced intraoperative bleeding and total transfusion in corpectomy group. Moreover, the procedure provided insights into the anatomy of tumor and spinal cord vasculature.

목적: 초음파 유도하 요추 4번 신경근 차단술을 시행함에 있어 시술 전 자기공명영상(magnetic resonance imaging, MRI) 계측의 유용성을 알아보고자 하였다. 대상 및 방법: 이 연구는 후향적 연구로 2016년 3월부터 2017년 12월까지 본원 외래에 방문한 환자 중 요추 4번 신경근의 병변이 확인되며 선정 기준에 합당한 71명의 환자를 대상으로 하였다. 2016년 3월부터 2017년 2월까지 MRI 계측 없이 신경근 차단술을 시행한 31명의 환자를 A군, 2017년 3월부터 2017년 12월까지 시술 전 MRI 계측을 통해 신경근 차단술을 시행한 40명의 환자를 B군으로 분류하였다. A군은 MRI 계측 없이 pararadicular 접근법을 통하여 주사를 시행하였고 B군은 시술 전 MRI로 측정한 계측치를 바탕으로 하여 초음파 유도하 주사를 시행하였다. 시술 전, 시술 3시간 후, 2주 후, 6주 후, 12주 후에 수치평가척도(numeric rating scale, NRS) 점수를 이용하여 통증 호전 정도를 판정하였다. 결과: 시술 3시간 후 양호 이상의 결과를 보인 경우는 A군에서 51.6%, B군에서 67.5%였으며 시술 2주 후 양호 이상의 결과를 보인 경우는 A군에서 48.4%, B군에서 70.0%였다. 시술 6주 후 양호 이상의 결과를 보인 경우는 A군에서 58.1%, B군에서 62.5%, 시술 12주 후 양호 이상의 결과를 보인 경우는 A군에서 67.7%, B군에서 62.5%였다. 시술 3시간 후, 2주차에 유의하게 B군이 A군보다 증상 호전에 좋은 결과를 보였다(p<0.05). 만족스런 통증 완화를 위해 2주차에서 6주차 사이에 A군의 경우 2.8회, B군의 경우 1.7회의 반복적인 시술이 시행되었다(p<0.05). 결론: 시술 전 MRI를 통한 계측을 먼저 시행하고 이를 참고하여 초음파 유도하 요추 4번 선택적 신경근 차단술을 시행하는 것은 환자의 시술의 성공률을 높여 시술 후 2주 이내의 초기 통증을 완화하는데 도움이 될 것으로 생각된다.

Purpose: This study compared the clinical and radiology results of arthrodesis between the anterior and transfibular approaches with a lateral malleolar-saving procedure in ankle arthritis. Materials and Methods: This study was a retrospective study of 31 cases who underwent ankle arthrodesis with the anterior approach (14 cases) and trans-fibular approach (17 cases). The remnant lateral malleolus was fixed during the trans-fibular procedure. The patients included 17 females and 14 males with a mean age of 57.2 (range 41~73) years; the mean follow-up was 30.4 (range 15~68) months. The clinical and radiology outcomes, including the American Orthopedic Foot & Ankle Society (AOFAS) scores, visual analog scale (VAS), and union time, were recorded. The complications and subjective satisfaction degrees were also recorded and compared between the two groups. Results: Clinically, the preoperative mean AOFAS score and VAS in the anterior approach group were 39.3 and 7.4, respectively, which changed to 61.9 and 3.1 postoperatively. In the trans-fibular approach group, the mean AOFAS score and VAS increased from 36.6 to 64.2 and 7.1 to 2.4, respectively. On the other hand, no significant differences in the clinical results were observed between the two groups. The time to achieve union was 9.2 and 11.6 weeks in the anterior and transfibular approach groups, respectively. Three patients (21%) complained of tenderness and discomfort around the fibular tip in the anterior approach group, and seven patients (41%) showed a gap between the talus and remnant lateral malleolus in the trans-fibular approach group. Conclusion: There was no difference in the clinical and radiological results between the anterior and transfibular approaches with a lateral malleolar saving procedure in ankle arthrodesis. Careful selection of the approach method according to the patient's preoperative condition is needed to prevent remnant discomfort or nonunion around the lateral malleolus.

Purpose : Soft tissue defect and exposed tendons and bones with concomitant infection in the foot and lower leg have to be covered with vascularized flap as the one stage treatment. Authors have performed 6 cases of pedicled dorsalis pedis island flaps under the loupes magnification and evaluated the benefits. Materials and methods : From 1994 through 2003, we have performed 6 pedicled dorsalis pedis island flaps for reconstruction of soft tissue defects in the foot and lower leg. The causes were trauma in 3 cases, skin necrosis and secondary infection after Achilles tendon repair in 2 cases and acute osteomyelitis in 1 case. Average age was 38 years and 5 cases were male and 1 female. The results of the procedure was evaluated by survival of the island flap, comfort in putting on shoes and walking, comfort in the donor site, comfort in the recipient site and range of motion of the ankle joint. Results : All pedicled dorsalis pedis island flaps survived except 1. Three cases felt discomfort in the dorsum of foot as the donor site and 1 case of the Achilles tendon ruptured and repaired showed limited dorsiflexion of ankle joint. Conclusion : Nonmicrosurgical pedicled dorsalis pedis island flaps under the loupes magnification are one of the useful treatment methods because procedure is rapid, survival is confident and overall reconstructive results are good.

Ankle sprain is one of the most common musculoskeletal injuries. Although most ankle sprains respond well to conservative measures, chronic instability following an acute sprain has been reported to occur in 20% to 40% of patients. Some individuals are eventually indicated for a lateral ankle ligament reconstruction due to persistent ankle instability. More than 80 surgical procedures have been described to address lateral ankle stability. These range from direct repair of the anterior talofibular ligament (ATFL) and of the calcaneofibular ligament (CFL) to reconstructions based on the use of autograft or allograft tissues. However, the best surgical option remains debatable. The modified $Brostr{\ddot{o}}m$ procedure is most widely used for direct ligament repair, but not always possible because of the poor ATFL or CFL quality or deficiency of these ligaments, which prevents effective shortening imbrication. Furthermore, the importance of a CFL reconstruction has been emphasized recently. On the other hand, it is difficult to achieve an efficient CFL reconstruction during the $Brostr{\ddot{o}}m$ procedure. Others have reported that an anatomic reconstruction of injured ligaments restores the normal resistance to anterior translation and inversion without restricting subtalar or ankle motion, and as a result, anatomic reconstructions for lateral ankle instability utilizing an autograft or allograft tendon have gained popularity.
