Abstract
BACKGROUND In patients with chronic lower extremity (LE) wounds, chronic osteomyelitis confers additional complexity to achieving adequate treatment. Previous reviews demonstrate increased rates of osteomyelitis recurrence in patients who receive muscle flaps compared with fasciocutaneous flaps for LE limb salvage; however, these studies were not limited to atraumatic populations who receive exclusively free flaps. Thus, this study compared rates of recurrence in chronic osteomyelitis patients undergoing LE reconstruction with fasciocutaneous versus muscle free flaps. METHODS Patients undergoing free tissue transfer (FTT) between July 2011 and July 2021 were retrospectively reviewed. Patients were stratified into fasciocutaneous and muscle free flap groups. Primary outcomes included osteomyelitis recurrence, flap complications, limb salvage, and ambulatory status. RESULTS Forty-eight patients with pathologic diagnosis of chronic osteomyelitis of the wound bed were identified, of which 58.3% received fasciocutaneous (n = 28) and 41.7% received muscle flaps (n = 20). The most common comorbidities included diabetes mellitus (n = 29, 60.4%), peripheral neuropathy (n = 27, 56.3%) and peripheral vascular disease (n = 24, 50.0%). Methicillin-resistant or methicillin -sensitive Staphylococcus aureus were the most common pathogen in 18.7% (n = 9) of procedures. The majority of patients underwent a median of three debridements followed by negative pressure wound therapy prior to receiving FTT. At a median follow-up of 16.6 months, the limb salvage and ambulatory rates were 79.2 (n = 38) and 83.3% (n = 40), respectively. The overall rate of microsurgical flap success was 93.8% (n = 45). Osteomyelitis recurred in 25% of patients (n = 12) at a median duration of 4.0 months. There were no significant differences in rates of osteomyelitis recurrence, flap complications, limb salvage, ambulation, and mortality. On multivariate analysis, flap composition remained a nonsignificant predictor of osteomyelitis recurrence (odds ratio: 0.975, p = 0.973). CONCLUSION This study demonstrates that flap composition may not influence recurrence of osteomyelitis following free flap reconstruction of chronic LE wounds, suggesting that optimal flap selection should be based on wound characteristics and patient goals.

Abstract
Background The goals of reconstruction have progressed from filling a defect to enhancing function and aesthetic appearance. We aimed to achieve better aesthetic and functional outcomes in terms of shoe fitting and mobility. This is accomplished via a classification of the subunits and aesthetic considerations of the lower limb. Methods Between April 2017 and December 2021, 66 cases of lower extremity free fasciocutaneous flap reconstruction cases were included in this retrospective study. Data parameters include age, sex, comorbidities, etiology of lower limb wounds, choice of free flap reconstruction, recipient arterial vessels, complications of flap reconstruction, and need for secondary debulking procedures. Physiotherapy records were also examined to determine the time to independent ambulation. Results In total, 66 subjects were identified. The mean age was 48.6. An estimated 74.2% (n = 49) were men, 50% (n = 33) had diabetes, and 16.6% (n = 11) had peripheral vascular disease. Of the total wounds, 65.1% (n = 43) were caused by infection, whereas the remaining 34.9% (n = 23) were due to trauma. Of the cases, 72.7% (n = 48) had free anterolateral thigh flap reconstruction, 25.8% (n = 17) were reconstructed with superficial circumflex iliac artery perforator flaps, and 1.5% (n = 1) was reconstructed with medial sural artery perforator flaps. Cases that required secondary debulking procedures comprised 7.6% (n = 5). Conclusions Free fasciocutaneous flaps are useful in lower extremity reconstruction. Based on the subunit principle and aesthetic considerations for lower limb reconstruction, it can aid in optimizing functional rehabilitation and decreasing secondary procedures.

Abstract
INTRODUCTION Limb salvage has become the standard of care for lower extremity tumors because of improvements in adjuvant treatments and reconstructive techniques. While there is literature assessing pediatric lower extremity free flap reconstruction in the setting of trauma, there is a paucity of literature that analyzes oncologic free flap reconstruction in this patient population. We report our long-term experience and evolution of care for lower extremity oncologic free flap reconstruction in pediatric patients. METHODS This is a retrospective case series of all patients ≤18 years of age who underwent oncologic soft-tissue microvascular reconstruction of the lower extremity, from 1992 to 2021. Data were collected for patient demographics, oncologic treatment, operative details, and post-operative outcomes. Functional outcomes were assessed by weight bearing status, ambulation, and participation in activities-of-daily-living (ADLs), and musculoskeletal tumor society (MSTS) scores. RESULTS Over the 30-year study period, inclusion criteria were met by 19 patients (11 males, 8 females) with a mean age of 13.8 years and a mean follow-up of 5.3 years. At last follow-up, 13 patients (68.5%) were alive. The most common pathology was osteogenic sarcoma (13 patients, 68.5%). Sites of reconstruction were the hip (n = 1), thigh (n = 5), knee (n = 4), leg (n = 7), and the foot (n = 2). The most commonly used flaps were latissimus dorsi (n = 8), gracilis (n = 4), and anterolateral thigh ± vastus (n = 4). Postoperative complications occurred in nine patients (43%). Overall flap success rate was 95%. At latest follow-up, ambulation without assistive device was obtained in 11 patients (58%), full weight bearing was achieved by 13 patients (68.5%), and ADLs could be performed independently by 13 patients (68.5%). Mean MSTS score was 23.1/30. CONCLUSION Microvascular reconstruction for oncological lower extremity defects in the pediatric population has high limb salvage rates and good functional outcomes.

Abstract
Treatment of complex ischemic lower leg defects with exposure of deep anatomic structures represents a considerable challenge to involved specialties. In selected patients, limb salvage can be achieved as an alternative to major amputation by means of a combined approach including arterial reconstruction and subsequent free flap transfer. Arterial reconstruction can be performed either by endovascular or open surgical treatment (bypass reconstruction or implantation of an arteriovenous loop) preliminary to defect reconstruction using microsurgical free flap transplantation. Whereas the aim of the arterial reconstruction comprises the establishment of sufficient perfusion and creation of adequate target vessels for the free flap transfer, the selection of the appropriate flap entity depends on the extent of the wound as wells as on the presence of osteomyelitis. Arterial reconstruction and defect reconstruction can be performed as one-stage or two-stage procedure and has become an established and feasible treatment approach in centers. Evaluation of microperfusion by means of indocyanine green can further increase safety and feasibility of this method. Against this background, combined arterial reconstruction and subsequent free flap transfer provides excellent results in terms of amputation free survival and postoperative mobility. Essential is however an individualized decision making in consideration of patient selection and possible contraindications. This approach may be evaluated in mobile patients with complex wounds prior to major amputation.

Usefulness of indocyanine green angiography in the intraoperative evaluation of recipient vessels for microsurgical lower extremity reconstruction in ischemic vasculopathy: Report of three cases. Microsurgery 2023; 43:611-616. [PMID: 37280042 DOI: 10.1002/micr.31071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 04/03/2023] [Accepted: 05/25/2023] [Indexed: 06/08/2023]
Abstract
Choosing reliable recipient vessels is crucial for successful free flap reconstruction of lower extremity defects, especially in patients with ischemic vasculopathy. This report describes our experience with the intraoperative use of indocyanine green angiography (ICGA) for selecting recipient vessels in lower extremity free flap reconstruction cases. Three patients with lower extremity defects and ischemic vasculopathy underwent free flap reconstruction. Intraoperatively, the candidate vessels were evaluated using ICGA. In the first case, a 10 × 6 cm defect on the anterior side of the lower third of the leg caused by minor trauma and associated with peripheral arterial occlusive disease was reconstructed using a super-thin anterolateral thigh flap based on one perforator. In the second case, a 12 × 8 cm defect on the posterior side of the right lower leg caused by a dog bite and associated with severe atherosclerosis throughout all three major vessels in the lower leg was reconstructed using a muscle-sparing latissimus dorsi myocutaneous flap. In the third case, a 13.5 × 5.5 cm defect on the right lateral malleolar region, where the peroneus longus tendon was exposed due to Buerger's disease, was reconstructed using a one perforator-based super-thin anterolateral thigh flap. In all cases, ICGA was used to evaluate the functionality of the candidate recipient vessels. In two cases, the candidate vessels showed acceptable blood flow, and the operations proceeded as planned. In the third case, the planned vessels of posterior tibial vessels were not identified to have sufficient blood flow, and one of their branches showing enhancement in ICGA was selected and used as a recipient vessel. All flaps survived completely. No adverse events occurred during the follow-up period of postoperative 3 months. Our results suggest that ICGA may be a valuable diagnostic tool for evaluating the quality of candidate recipient vessels in cases where their functionality cannot be guaranteed with conventional imaging modalities.

Abstract
This case series aimed to investigate the result of venous end-to-side (ETS) anastomosis in the extremities to contribute to a meta-analysis to evaluate the postoperative complications of venous ETS anastomosis in the extremities. This was a single-center case series and meta-analysis of patients who underwent venous ETS anastomosis for free-flap reconstruction of the extremities. We reviewed the records of 41 free flaps in 40 patients and performed a comprehensive search of PubMed, Scopus, and Web of Science for studies published from inception to December 2022. Primary outcomes were venous thrombosis, takebacks, and total and partial flap failures. Complication rates and confidence intervals were calculated using a random-effects model. In our case series, four (12.2%) patients with five flaps were taken back to the operating room, three (7.3%) flaps were due to venous thrombosis, and three (7.3%) flaps ultimately resulted in total flap failure. Our meta-analysis demonstrated the following complication rates: 4.0% (95% confidence interval [CI], 0-18.1%; I2 = 0%) for venous thrombosis, 8.5% (95% CI, 0-21.8%; I2 = 0%) for takebacks, 5.8% (95% CI, 0-18.3%; I2 = 0%) for total flap failure, and 8.8% (95% CI, 0-28.4%; I2 = 0%) for partial flap failure. Our case series and meta-analysis showed that the result of venous ETS anastomosis in the extremities was positive, and this technique was effective for addressing venous size discrepancy; although, its superiority to end-to-end anastomosis could not be established.
