RESUMO

BACKGROUND: Free fascial flaps from the anterolateral thigh (ALT) were used to reconstruct soft tissue defects after trauma to the ankle. This modification was compared to the conventional fasciocutaneous method. MATERIAL AND METHODS: The defect size, the thickness of the subcutaneous fat layer on the thigh and the extent of the soft tissue covering the ankle were determined retrospectively. The evaluations were compared between fascial (Fo) and fasciocutaneous flaps (Fc). The foot and ankle outcome score (FAOS) was used. Esthetic outcome surveys were carried out. RESULTS: A total of 18 isolated fractures of the ankle were evaluated. In 94% of the cases a closed soft tissue damage predominated. After fracture fixation using a plate, soft tissue defects with a mean area of 40.4 ± 13.1 cm2 (28-76 cm2) developed. The thickness of the soft tissue covering over the affected malleoli increased significantly in both groups as a result of the flap surgery (4.5 ± 0.7 vs. 21.1 ± 6.4 mm, p < 0.05). A significant difference was found when comparing the body mass index (BMI) between the groups (Fc 26.3 ± 3.4 kg/m2 vs. Fo 30.1 ± 4.2 kg/m2, p < 0.05). For both groups there was a positive correlation (r = 0.843) between the BMI and the thickness of the epifascial fat layer of the thigh. The FOAS survey revealed 75.9 ± 28.9 and 47.9 ± 32.4 points, respectively, for "function in daily life" and "foot and ankle-related quality of life". The esthetic reconstruction result was rated as "acceptable" by 55% and as "good" by 45%. DISCUSSION: The modified method of a free fascial flap from the ALT can be useful in situations where a bulky flap makes it difficult to fit it into the defect.

RESUMO

Injuries of lymph vessels can occur due to trauma or surgery and may result in significant difficulties for patients. Wound healing is often severely impaired and patients may need extensive surgical treatment. A case of iatrogenic lymph vessel injury after excision of a skin tumor in the axillary region is reported, as is the reconstructive procedure by lymphaticovenous anastomosis.

RESUMO

Soft tissue sarcomas (STS) arising in the distal lower extremities pose a therapeutic challenge due to concerns of functional morbidity. The impact of surgical margins on local recurrence­free survival (LRFS) and overall survival (OS) still remains controversial. The aim of this study was to identify prognostic indicators of survival and functional outcome in patients with STS of the distal lower extremities through a long­term follow­up. Between 1999 and 2014, 120 patients with STS of the foot, ankle and lower leg were treated surgically at our institution. The median follow­up was 6.3 years. The results reveal that the 5­year estimate of the OS rate was 80.0% [95% confidence interval (CI): 69.6­87.1] for the entire series. Surgical margins attained at the resection of the primary tumor did not influence OS significantly [5­year OS: R0 80.5% (69.7­87.9) vs. R1 74.1% (28.9­93.0); P=0.318]. Within the R0 subgroup, negative surgical margin widths ≤1 and >1 mm led to similar outcomes, as well as ≤5 and >5 mm, respectively. In the multivariate analysis, significant adverse prognostic features included male gender and age >60 years at the time point of primary diagnosis. In conclusion, the data from this study could not underscore the long­term benefit of negative margins achieved at the resection of the primary tumor. Surgical efforts should aim at function­sparing resections when feasible with negative margins. Here, close negative margins seem to be adequate.

RESUMO

INTRODUCTION: Solid malignancies at the foot and ankle region are rare and include mainly soft-tissue sarcomas, bone sarcomas, and skin malignancies. Complete surgical resection with clear margins still remains the mainstay of therapy in these malignancies. However, attainment of negative surgical margins in patients with locally advanced tumors of the foot and ankle region may require extensive surgery and could result in loss of extremity function. In these circumstances, plastic surgical techniques can frequently reduce functional impairment and cover soft-tissue defects, particularly in cases of large tumor size or localization adjacent to critical anatomic structures, thereby improving the quality of life for these patients. The aim of this article is to illustrate the various treatment options of plastic surgery in the multimodal therapy of patients with malignant tumors of the foot and ankle region. MATERIALS AND METHODS: This article is based on the review of the current literature and the evaluation of the author's own patient database. RESULTS: The local treatment of malignant extremity tumors has undergone major changes over the last few decades. Primary amputations have been increasingly replaced by limb-sparing techniques, preserving extremity function as much as possible. Although defect coverage at the foot and ankle region is demanding due to complex anatomical features and functional requirements, several plastic surgical treatment options can be implemented in the curative treatment of patients with malignant solid tumors in this area. Soft-tissue defects after tumor resection can be covered by a variety of local flaps. If local flaps are not applicable, free flap transfers, such as the anterolateral thigh flap, parascapular flap, or latissimus dorsi flap, can be utilized to cover nearly all kinds of defects in the foot and ankle region. CONCLUSION: Soft-tissue reconstruction in the foot and ankle region is a vital component of limb-sparing surgery. It enables complete resection of locally advanced tumors and subsequent adjuvant radiotherapy. Modern plastic surgical techniques should, therefore, be integrated in the multimodal treatment concept of malignancies in the foot and ankle region.
