Purpose: Minor foot amputations are performed for recurrent or infected ulcers or osteomyelitis of the diabetic feet. Patients may require a large amount of bone resection for wound closure. On the other hand, this results in more foot dysfunction and a longer time to heal. The authors describe fillet flap coverage to avoid more massive resection in selected cases. This study shows the results of fillet flap coverage for the closure of diabetic foot minor amputation. Materials and Methods: This was a retrospective case series of patients who underwent forefoot and midfoot amputation and fillet flap for osteomyelitis or nonhealing ulcers between March 2013 to November 2017. In addition, the patient comorbidities, hospital days, complications, and duration to complete healing were evaluated. Results: Fourteen fillet flap procedures were performed on 12 patients. Of those, two had toe necrosis, nine had forefoot necrosis, and three had midfoot necrosis. Eleven forefoot amputations and three midfoot amputations were performed. Among forefoot necrosis after a fillet flap, three patients had revision surgery for partial necrosis of the flap, and two patients had an additional amputation. Two patients had additional amputations among those with midfoot necrosis. By the fillet flap, the amputation size was reduced as much as possible. The mean initial healing days, complete healing days, and hospital stay was 70.6 days, 129.0 days, and 60.0 days, respectively. Conclusion: The fillet flap facilitates restoration of the normal foot contour and allows salvage of the metatarsal or toe.

Augmentation mammoplasty is one of the most popular cosmetic surgeries, but there is a high reoperation rate (29.7%) commonly due to capsular contracture, implant malpositioning, infection, and unsatisfactory size. Although infection only accounts for 2% of cases, its management is very challenging, especially with nontuberculous mycobacteria (NTM) infection. Breast prosthetic NTM infection is a rare but is a disastrous condition with an incidence of approximately 0.013%. Immediate salvage reimplantation is usually not suggested, and most studies recommend a gap of 3 to 6 months after combination antibiotics therapy before reimplantation. However, delayed reimplantation often leads to great psychological stress and struggle between the doctor and patient. We present the case report of successful reimplantation in treating prosthetic NTM infections in a 28-year-old female. We discuss a novel technique "transaxillary capsulorrhaphy" to correct the bottoming-out deformity. One year after the combination of antibiotics and surgery, the follow-up computed tomography scan showed complete remission of NTM without recurrence. We discuss the surgical technique in detail. The 1-year follow-up assessment (photos and dynamic video) revealed good cosmesis and reliable correction using the new technique. This report is the first formal description and discussion of one-stage reimplantation following NTM infections. Transaxillary capsulorrhaphy allows for a successful salvage operation when an implant is displaced. This approach provides highly favorable result in eastern women undergoing revision augmentation mammoplasty. This study reflects level of evidence V, considering opinions of respected authorities based on clinical experience, descriptive studies, or reports of expert committees.

Objectives: Maxillary cancer is notorious for its poor prognosis because it is usually detected lately and the majority of patients have advanced disease. Especially when the cancer extended to infratemporal fossa or pterygopalatine fossa it is very difficult to remove all the involved structure by conventional maxillectomy. In these cases we have used radical maxillectomy through lateral approach. We tried to figure out the clinical significance of this procedure. Material and Methods: This study retrospectively analyzed 23 patients with squamous cell carcinoma of the maxillary sinus who underwent surgical treatment for cure. Among them 17 patients(group A) were treated with initial surgery and 6 patients(group B) underwent salvage surgery after radiotherpy. Radical maxillectomy was performed in 12 patients and conventional total maxillectomy in 11 patients. Results: In group A, 3 out of 9 total maxillectomy case and none of 8 radical maxillectomy case were recurred. In group B one patient died of postoperative complication and among the other 5 patients only one out of 3 radical maxillectomy was salvaged and 2 total maxillectomy cases were died of intercurrent disease. Conclusion: Wide surgical dissection of pterygopalatine fossa and infratemporal fossa may improve the survival rate in patients with posterior wall invasion of maxillary sinus.

Background Knee disarticulations (KD) are most commonly employed following trauma or tumor resection but represent less than 2% of all lower extremity amputations performed in the United States annually. KDs provide enhanced proprioception, a long lever arm, preservation of adductor muscle insertion, decreased metabolic cost of ambulation, and an end weight-bearing stump. The role for KDs in the setting of arterial insufficiency or overwhelming infection is less clear. The purpose of this study is to describe technique modifications and report surgical outcomes following KDs at a high-volume Limb Salvage Center. Methods A retrospective study of medical records for all patients who underwent a through-knee amputation performed by the senior author (C.E.A.) between 2004 and 2012 was completed. Medical records were reviewed to collect demographic, operative, and postoperative information for each of the patients identified. Results Between 2004 and 2012, 46 through-knee amputations for 41 patients were performed. The mean patient age was 68 and indications for surgery included infection (56%), arterial thrombosis (35%), and trauma (9%). Postoperative complications included superficial cellulitis (13%), soft tissue infection (4%), and flap ischemia (4%) necessitating one case of surgical debridement (4%) and four transfemoral amputations (9%). 9 (22%) patients went on to ambulate. Postoperative ambulation was greatest in the traumatic cohort and for patients less than 50 years of age, P<0.05. Alternatively, diabetes mellitus and infection reduced the likelihood of postoperative ambulation, P<0.01. Conclusions Knee disarticulations are a safe and effective alternative to other lower extremity amputations when clinically feasible. For patient unlikely to ambulate, a through-knee amputation maximizes ease of transfers, promotes mobility by providing a counterbalance, and eliminates the potential for knee flexion contracture with subsequent skin breakdown.

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.

사지 구제술이 보편화된 후 슬 관절 주위 골육종 환자의 재건 방법은 술자의 선호도에따라 차이가 있을 수 있으나 비교적 표준화 되어 있다. 현재 주로 시행되는 사지 구제술 방법으로는 크게 인공관절 치환술, 동종골 이식술이 있다. 인공관절 치환술의 경우 매우 안정적이며 술후 기능적으로도 양호한 방법으로 알려져 있으나, 궁극적으로 파손에 의한 제거술 시행이 필수적인 단점이 있다. 장기적인 관점에서 볼때 이식골을 이용한 재건술은 큰 장점을 갖고 있다. 하지만, 동종골의 사용은 요구되는 크기와 모양을 쉽게 구하기 어렵다는 단점이 있으며, 자가골 이식술은 수술 절제연이 안전하고, 그 적응증이 확립된 경우에만 사용해야 한다는 단점을 갖고 있다. 사지 구제술에 있어 분절 절제법은 골간의 병변에 있어 그 유용성이 확립되어 있으나, 골간단의 병변에 있어서는 시행 적응증이 널리 알려져 있지 않다. 저자들은 17세 환자의 근위 경골 내측과에 국한적으로 발생한 골육종의 증례에서 내측과 절제만으로도 안전한 절제연을 얻을 수 있을 것으로 사료되어 내측과 절제술 및 저온 열처리 자가골 이식술을 시행하였다. 본 술식은 추가적인 성장이 예상되는 소아환자에게 시행하였을 경우, 추후 파손 발생시에도 반측 치환술로 치환 가능한 방법으로 생각되어 보고하는 바이다.

Background This study was designed to introduce the feasibility of toe tissue transfer without venous outflow for fingertip reconstruction. Methods Five cases of fingertip defects were treated successfully with this method. Four cases were traumatic fingertip defects, and one case was a hook-nail deformity. The lateral pulp of a great toe or medioinferior portion of a second toe was used as the donor site. An arterial pedicle was dissected only within the digit and anastomosis was performed within 2 cm around the defect margin. The digital nerve was repaired simultaneously. No additional dissection of the dorsal or volar pulp vein was performed in either the donor or recipient sites. Other surgical procedures were performed following conventional techniques. Postoperative venous congestion was monitored with pulp temperature, color, and degree of tissue oxygen saturation. Venous congestion was decompressed with a needle-puncture method intermittently, but did not require continuous external bleeding for salvage. Results Venous congestion was observed in all the flaps, but improved within 3 or 4 days postoperatively. The flap size was from $1.5{\times}1.5cm^2$ to $2.0{\times}3.0cm^2$. The mean surgical time was 2 hours and 20 minutes. A needle puncture was carried out every 2 hours during the first postoperative day, and then every 4 hours thereafter. The amount of blood loss during each puncture procedure was less than 0.2 mL. In the long-term follow-up, no flap atrophy was observed. Conclusions When used properly, the free toe tissue transfer without venous anastomosis method can be a treatment option for small defects on the fingertip area.

A total of 44 patients with extremity soft tissue sarcomas had received conservative surgery and radiation therapy in the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University College of Medicine between Jan. 1980 and Dec. 1990. Initial surgical treatment consisted of intracapsular excision in 33 patients $(75\%),$ marginal excision in 9 patients, and wide excision in two patients. Total radiation doses were between 40Gy and 65Gy (median 60 Gy). Median follow-up period was 47 months. Overall actuarial 5-year survival rate was $76.9\%$ and 5-year recurrence free survival rate was $39.3\%.$ There was no statistically significant prognostic factors but the 5-year survival rates tended to be decreased in the patients with high grade tumors and treated with narrow surgical extent. Sixteen patients recurred during fellow-up (16/31, $51.6\%).$ The incidence of initial local recurrence was $22.6\%$ (7/31) and distant metastasis was $29\%(9/31).$ Of the 7 who did not have metastasis at diagnosis of local recurrence, 5 were submitted to a salvage treatment. All of them achieved local control and distant metastasis appeared in three of them. In conclusion, conservative surgery and radiation therapy in the patients with extremity soft tissue sarcomas was the effective treatment modality.

Treatment of calcaneal fraclure is difficult and full of controversy still and choice of treatment of the displaced intracalcaneal fracture is not available yet. Furthermore, the treatment of old calcaneal fracture with displaced subtalar joint or malunited calcaneal fracture is really difficult and painful to solve the problem other than subtalar arthrodesis, ignoring conservative treatment, excision of bone mass and/or adhesiolysis, which is/are a kind of palliative or salvage treatment in stead of definitive treatment that restores smooth articular surface of the subtalar joint as far as we can. Authors had some experiences treating this difficult old and displaced calcaneal fractures. Some of them were malunited already. Hereby we report our favorable results to treat the fractures with surgical reduction (reconstruction) and internal fixation without bone graft. We recommend reconstruction of the displaced subtalar joint even though it is not congruent and partly gone to get subtalar motion insead of palliative operation such as subtalar fusion, which can be done later and long term potential cause of mid tarsal arthrosis of the foot.
