슬와부위의 연부조직육종은 사지의 연부조직 육종 중 5% 이하를 차지하는 드문 질환이다. 주요 혈관과 신경이 지나가는 슬와, 주와, 서혜부와 같은 구획외 공간에서는 사지 구제술 시 적절한 절제연을 얻으면서 절제를 시행하기가 쉽지 않으며 불가피하게 변연부 절제를 시행해야 하는 경우도 있다. 슬와부 종양 절제시는 후방 도달법을 시행하는 경우가 일반적이다. 크기가 작고 주변 조직에 유착이 없는 종양일 경우 후방 도달법으로 신경다발막과 혈관외막을 박리하여 종양을 쉽게 절제할 수 있다. 그러나 종양의 크기가 크고 주변조직으로 침범이 있는 경우에는 종양의 절제 자체가 어려울 수 있다. 이런 경우는 절단술의 상대적 적응증이며 종양이 전방 및 후방 구획을 동시에 침범하였을 경우에는 절단술이 불가피하다고 생각되는 경우가 많았다. 저자들은 전방 및 후방 구획을 동시에 침범한 연부조직종양을 골 외측으로 종괴를 형성한 골종양으로 간주하여 근위 경골과 비골을 종양과 함께 절제함으로써 적절한 절제연을 얻으면서 사지구제술이 가능하였기에 보고하는 바이다.

The radial artery superficial palmar branch free flap is based on the perforators of the superficial palmar branch of the radial artery and its venae comitantes. This flap can be used as a sensible flap including palmar cutaneous branch of the median nerve. Forty radial artery superficial palmar branch free flaps were performed at Centum Institute during October 2010 to December 2011. There were 32 males and 8 females and their mean age were 48 years (range 30 to 66 years). The thumb injured in 13 patients, the index finger in 16 patients, the middle finger in 4 patients, the ring finger in 2 patients, and the little finger in 5 patients. The mean size of the flap was $2.5{\times}3.5$ cm(range $2{\times}2.5$ to $3{\times}7$ cm). The donor site was always closed primarily. The overall survival rate was 90.2 percent. The flaps showed well-padded tissue with glabrous skin. All patients have touch sensation and showed 12 mm two point discrimination in an average(range 8 to 15 mm). Donor site morbidity was conspicuous. One patient showed unsightly scar. Early postoperative range of motion of the affected thumb showed slightly limited radial and palmar abduction. But it improved after postoperative 2 months, and patients did not complaint limitation of motion. In conclusion, the radial artery superficial palmar branch free flap can be used as an option for soft tissue reconstruction of finger defects where local or island flaps are unsuitable.

Purpose: Distally based superficial sural artery island flap has some disadvantages such as postoperative flap edema, congestion, and partial necrosis of the flap margin. Venous congestion is an area of considerable concern in distally based superficial sural artery fasciocutaneous flap and is one of the main reasons for failure, particularly when a large flap is needed. However, we could decrease these disadvantages by means of venous superdrainage. Methods: From June of 2006 to June of 2007, a total of two patients with soft tissue defects of lower one third of the leg underwent venous supercharging distally based superficial sural artery island flap transfer. The distal pivot point of this flap was designed at septocutaneous perforator from the peroneal artery of the posterolateral septum, which was 5 cm above the tip of the lateral malleolus. Briefly, this technique is performed by anastomosing the proximal end of the lesser saphenous vein and collateral vein to any vein in the area of the recipient defect site. Results: No venous congestion was noted in any of the two cases. No other recipient or donor-site complications were observed, except for minor wound dehiscence in one case. In 3 to 6 months follow-up, patients had minor complaints about lack of sensation in the lateral dorsal foot. Conclusion: The peroneal artery perforator is predictable and reliable for the design of a distally based superficial sural artery island flap. Elevation of the venous supercharging flap is safe, easy, and less time consuming. In conclusion, the venous supercharging distally based superficial sural artery island flap offers an alterative to free tissue transfer for reconstruction of the lower extremity.

Purpose: In recent decades, amputation is still recommended for patients with extensive lower extremity wounds requiring coverage. Although the feet contribute relatively little to total body surface area, they are essential organ for ambulation, and a high mortality rate after amputation has been reported. We report on 10 challenging cases of a mangled foot which was reconstructed using an anterolateral thigh (ALT) free flap, and analyze the advantages and disadvantages of this technique. Materials and Methods: This retrospective study was conducted on 10 patients who underwent reconstructive surgery on a foot. Patients' charts were reviewed for age, sex, causes, defect size and site, flap size and type, flap type, and complications. Cases with a defect size of > $100cm^2$ were included. Results: Seven of the 10 patients were male, and overall mean age was 38.5 years (range, 22 to 61 years). Mean defect size was $179.6cm^2$ (range, 104 to $330cm^2$), and mean flap size was $193cm^2$ (range, 120 to $408cm^2$). Three cases were reconstructed with a musculocutaneous free flap and seven cases were reconstructed with a fasciocutaneous free flap. There were two occurrences of local wound complication. All ten flaps survived well, however five patients underwent a debulking procedure to reduce flap volume. Conclusion: Reconstruction of a near completely degloved soft tissue defect or a wide defect containing two or more surfaces of extremity with an ALT free flap was performed. The purpose of this case study is to report on free tissue transfer using the ALT flap for salvage of the lower extremity.

The syndrome of the trephined is a neurologic phenomenon that manifests as sudden decline in cognition, behavior, and sensorimotor function due to loss of intracranial domain. This scenario typically occurs in the setting of large craniectomy defects, resulting from trauma, infection, and/or oncologic extirpation. Cranioplasty has been shown to reverse these symptoms by normalizing cerebral hemodynamics and metabolism. However, successful reconstruction may be difficult in patients with complex and/or hostile calvarial defects. We present the case of a 48-year-old male with a large cranial bone defect, who failed autologous cranioplasty secondary to infection, and developed rapid neurologic deterioration leading to a near-vegetative state. Following debridement and antibiotic therapy, delayed cranioplasty was accomplished using a polyetheretherketone (PEEK) implant with free chimeric latissimus dorsi/serratus anterior myocutaneous flap transfer for vascularized resurfacing. Significant improvements in cognition and motor skill were noted in the early postoperative period. At 6-month follow-up, the patient had regained the ability to speak, ambulate and self-feed-correlating with evidence of cerebral/ventricular re-expansion on computed tomography. Based on our findings, we advocate delayed alloplastic implantation with total vascularized soft tissue coverage as a viable alternative for reconstructing extensive, hostile calvarial defects in patients with the syndrome of the trephined.

Background Groin wounds occurring after vascular surgical site infection, oncologic resection, or occasionally orthopedic surgery and trauma may represent a surgical challenge. Reconstruction of these defects by the usual workhorse flaps may be contraindicated following previous surgery and in patients with lower limb lymphedema or extreme morbidity. Methods This study included 15 consecutive patients presenting with inguinal wounds after vascular or general surgery that required debridement and soft tissue coverage. All cases had absolute or relative contraindications to conventional reconstructive techniques, including a compromised deep femoral artery network, limb lymphedema, scarring of potential flap harvesting sites, or poor overall condition. Abdominal adipocutaneous excess enabled the performance of adipocutaneous advancement flaps in an abdominoplasty-like fashion. Immediate and long-term outcomes were analyzed. Results Soft tissue coverage was effective in all cases. Two patients required re-intervention due to flap-related complications (venous congestion and partial flap necrosis). All patients fully recovered over a mean±standard deviation follow-up of 2.4±1.5 years. Conclusions Abdominal flaps can be an effective and simple alternative technique for inguinal coverage with reproducible outcomes. In our experience, the main indications are a compromised deep femoral artery network and poor thigh tissue quality. Relative contraindications, such as previous open abdominal surgery, should be considered.

임플란트 치료의 유지단계에서 임플란트 주변 연조직의 문제 중 하나는 부착조직의 부족한 범위이다. 각화 조직은 치아 및 임플란트 주변에서 구강 위생의 유지 및 개선에 있어서 중요한 역할을 한다. 유리 치은 이식술은 연조직 부족을 해결하고 임플란트 보철의 장기간의 예후를 증가시키기 위해 최적의 임플란트 주변 건강을 제공한다. 그러나 유리 치은 이식술 치료를 받은 환자들은 구개와 같은 공여부 상의 통증 및 불편감을 호소한다. 뿐만 아니라 술자에게 있어 기술적인 난이도를 요구하며, 시간이 오래걸리고 이상적인 형태와 비교하였을 때 종종 조직의 색깔 차이가 발생하는 등의 단점이 있다. 근단변위판막술은 임플란트 2차 수술과 동반하여 또는 이후에 간단히 부착 조직을 증대시키기 위해 선택된다. 이번 증례보고에서는 유리치은이식술을 대신하여 작은 범위의 임플란트 부위에서 근단변위판막술을 통한 임플란트 주변 각화 조직의 폭경이 성공적으로 증가했음을 보이고자 한다.

Moderate soft-tissue defects need stable coverage, ideally with tissue of similar characteristics and low donor site morbidity. We propose a simple technique for the coverage of moderate skin defects in the limbs. It allows intraoperative transformation of a propeller perforator flap (PPF) into a keystone design perforator flap (KDPF) in cases of unsatisfying perforator vessel or in cases of unpredictable intraoperative events. Between March 2013 and July 2019, nine patients with moderate soft-tissue defects (mean defect size 4.5 × 7.6 cm) in the limbs (two on the upper limbs and seven on the lower limbs) were covered using this technique. We performed four PPFs and five KDPFs. The mean follow-up was 5 months. There was one complication, partial distal tip necrosis in a PPF located in the leg, which healed by secondary intention within 3 weeks. The donor site was closed directly in all cases. No functional impairments were noted regardless of the perforator flap utilized. This technique enables us to employ flexible surgical strategies and allows us to make adjustments based on the patient's vascular anatomy.

Free flap reconstruction of the foot has become one of the standard procedures at the present time, but choice of a free flap for the soft tissue defect of the foot according to location and size remains controversial. We evaluated the results of free flap reconstruction for the soft tissue defects of the foot. Twenty seven free flaps to the foot were performed between May 1986 and December 2000 in the department of Orthopedic Surgery. Patient age ranged from 3 to 60 years. Male to female distribution was 20:7. Mean follow-up period was 30.5 months which ranged from 12 months to 60 months. The indications for a specific flap depended on the location and extension of the foot defect. In weight-bearing area and amputation stump, the authors chose the sensate (reinnervated) dorsalis pedis flaps (n=7) and sensate radial forearm flaps (n=2). In nonweight-bearing area including dorsum of the foot and area around Achilles tendon, we performed nonsensate (non-reinnervated) free flap reconstructions which included dorsalis pedis flaps (n=5), groin flap (n=1), radial forearm flaps (n=6), scapular flaps (n=4), latissimus dorsi flaps (n=2). Twenty-six flaps transferred successfully (96.3%). The sensate flaps which were performed in weight-bearing area and amputation stumps survived in all cases and recovered protective sensation. Mean two-point discrimination was 26 mm at the last follow up. As a conclusion, the selection of a proper flap depends on the location and extension of the foot defect and patient's age. Fasciocutaneous flap including radial forearm flaps and dorsalis pedis flaps were the best choice in nonweight-bearing area. The sensate free flaps which are performed in the weight-bearing area and amputation stumps can produce better outcome than nonsensate free flap.
