Use of Free Internal Mammary Artery Perforator Flap Harvested With Minimally Invasive Approach for Facial Reconstruction: Report of Two Cases.

The internal mammary artery perforator (IMAP) flap has been widely used for chest wall and neck reconstruction. The color of its skin paddle closely resembles that of facial skin, making it attractive for facial reconstruction. However, there has been insufficient investigations reporting the use of free IMAP flap. Furthermore, even in such studies, somewhat invasive procedures, including rib cartilage resection, were employed to ensure sufficient pedicle length, potentially increasing donor morbidity. Our report presents two cases of successful facial defect reconstruction using a free IMAP flap harvested with minimal donor site damage, showing its feasibility. In the first case, a 48-year-old male underwent wide excision for a malignant melanoma on his right cheek, resulting in a 4 × 4.5 cm full-thickness defect. A free IMAP flap with a 2.5 cm pedicle, was harvested without rib cartilage resection, preserving IMA main trunk, and transferred with anastomosed to the angular vessels within the defect. The second patient presented with a 4.5 × 3.5 cm basal cell carcinoma on the left cheek, necessitating wide excision and leaving a 6 × 5 cm defect. A free IMAP flap was harvested with the same approach and successfully reconstructed the defect with connected to the superficial temporal vessels using vascular bridge. Both patients were discharged complication-free, with no recurrence during 24 and 15 months of follow-up, respectively. They were highly satisfied with the final skin color and texture outcomes. Harvesting a free IMAP flap while minimizing donor morbidity may offer an attractive option for facial reconstruction.

Management of a Complex, Recurrent Case of Medial Thigh Sarcoma With Pedicled Deep Inferior Epigastric Artery Perforator (DIEP) Lymphatic Flow-Through (LyFT) Flap and Secondary Anterolateral Thigh (ALT) Free Flap With Innervated Vastus Lateralis Anastomosed to Synthetic Artery Graft: A Case Report.

Soft-tissue sarcomas (STS) are rare solid tumors of mesenchymal cell origin and account for only 1% of adult malignancies. They tend to occur most commonly in the lower extremities. Reconstruction after sarcoma resection can be challenging, especially when important structures are involved and recurrences occur. Additionally, more attention is now being paid to reconstructing the lymphatic system to prevent lymphatic complications. In this case report, we presented the management of recurrent medial thigh sarcoma that necessitated multiple challenging reconstructions to provide valuable insights for lectures on similar cases. A 50-year-old male patient was diagnosed with an undifferentiated pleomorphic cell sarcoma (UPS) of the anteromedial thigh. After preoperative radiotherapy, a mass of 23 × 15 cm was removed, and reconstruction with a pedicled deep inferior epigastric artery perforator (p-DIEP) flap-based lymphatic flow through (LyFT) was performed. Six months later, the patient developed the first local recurrence with the presence of a distant metastasis. Following the tumor resection, the medial part of the DIEP flap was de-epithelized and buried in the defect for dead space obliteration. Another local recurrence arose 7 months after the second surgery. Therefore, a major debulking surgery involving the femoral neurovascular bundle was performed. The femoral artery was reconstructed with a synthetic graft, and the femoral vein with the great saphenous vein harvested from the contralateral thigh. A composite myocutaneous neurotized anterolateral thigh (ALT) flap from the contralateral thigh was used to obliterate the defect and restore the loss of function of the quadriceps femoris. Two lymphaticovenular anastomoses (LVAs) were performed at the ankle to reduce the risk of lymphatic sequelae. This case report highlights the importance of integrating various techniques to create a tailored approach that effectively addresses complex surgical requirements to avoid limb amputation and maintain functionality.

Early Penile and Donor Site Sensory Outcomes After Innervated Radial Forearm Free Flap Phalloplasty: A Pilot Prospective Study.

BACKGROUND: Radial forearm free flap phalloplasty (RFFF) is a set of complex reconstructive procedures aimed at creating an aesthetic and functional penis in transgender patients. Sensory recovery in the neophallus and donor site is crucial for optimizing outcomes, but the few prior studies that exist assess neophallus sensation at limited locations and time points. The purpose of this study was to prospectively quantify sensory outcomes in the neophallus and donor site following RFFF phalloplasty. METHODS: Sensation testing occurred prospectively over February 2019-January 2021 on Stage 1 RFFF phalloplasty patients using the Pressure Specified Sensory Device (PSSD). On the neophallus, one-point discrimination (1PS) pressure threshold and lengthwise sensory recovery were measured at six circumferential locations proximally to distally. On the donor site, 1PS was measured at three locations on the donor hand. RESULTS: Nineteen patients were included (average age 34.0 years old, range 18-53 years). Among patients that received neophallus testing (n = 13), eight had at least two follow-up appointments. Six of these patients had sensation as of their most recent measurement (75.0%), with an average of 73 days to regain sensation. There was a significantly greater proportion of patients with sensation at the right ventral (80.0% after 3 months vs. 11.1%-60.0% before 3 months, p = 0.024) and right lateral (100.0% after 3 months vs. 11.1%-60.0% before 3 months, p = 0.004) aspects of the neophallus over time. Pressure required to elicit sensation decreased by 18.0% from 1 week-1 month postoperatively to 3-7.7 months postoperatively in the right ventral neophallus (96.2 g/mm2 ± 11.3 g/mm2 to 56.6 ± 39.9 g/mm2, p = 0.037). Among patients that received donor site testing (n = 11), mixed effects regression analysis with random intercepts demonstrated significant changes in the thumb (3.4 g/mm2 ± 1.4 g/mm2, p < 0.05) and webspace (13.5 g/mm2 ± 4.9 g/mm2, p < 0.01) that returned to baseline at 3 months postoperatively (1.7 g/mm2 ± 1.0 g/mm2, p > 0.05, and 2.3 g/mm2 ± 4.0 g/mm2, p > 0.05, respectively). CONCLUSION: This pilot study demonstrates that quantitative sensory testing can be used to monitor post-phalloplasty sensory changes. Recovery was significantly associated with contralateral (i.e, right side in a left forearm RFF) aspects of the neophallus, suggesting a possible pattern of circumferential sensory innervation via RFFF sensory nerves. Future studies with a larger sample size and longer follow-ups are necessary to fully characterize sensory recovery in phalloplasty patients.

The Impact of Increased Body Mass Index on Patient Outcomes and Complications in Microsurgical Lower Extremity Reconstruction.

BACKGROUND: Elevated body mass index (BMI) is a known perioperative risk factor for complications such as delayed wound healing and infection. However, there is a gap in understanding how elevated BMI impacts outcomes after posttraumatic lower extremity (LE) microvascular reconstruction. METHODS: A retrospective review was performed at a level 1 trauma center between 2007 and 2022 of patients who underwent posttraumatic microvascular LE reconstruction. Demographics, flap/wound details, complications, and outcomes were recorded. Patients were stratified into BMI Center for Disease Control categories. RESULTS: A total of 398 patients were included with an average BMI of 28.2 ± 5.8. Nearly half (45%) of LE defects were located in the distal third of the leg, 27.5% in the middle third, and 34.4% in the proximal third. Most reconstructions utilized muscle-containing flaps (74.4%) compared with fasciocutaneous flaps (16.8%). Surgical approaches included free flaps (47.6%) and local flaps (52.5%). Class III obese patients were significantly more likely to be nonambulatory than nonobese patients (OR: 4.10, 95% CI 1.10-15.2, p = 0.035). At final follow-up, 30.1% of patients with Class III obesity were ambulatory, requiring either wheelchairs (42.3%) or assistance devices (26.9%). There were no significant differences in complication rates based on obesity status (0.704). The average follow-up time for the entire cohort was 5.8 years. CONCLUSIONS: BMI is critical for patient care and surgical decision-making in LE reconstruction. Further research is warranted to optimize outcomes for higher BMI patients, thereby potentially reducing the burden of postoperative complications and enhancing overall patient recovery.

Free medial plantar flap connection with a posterior tibial artery flap and its modification for combined dorsal and plantar foot defects - two case reports.

Reconstruction of large soft tissue foot defects were considered a difficult issue due to weight-bearing function of the foot. The reconstruction becomes more difficult when both plantar and dorsal soft tissues are involved. The options for the reconstruction were variable, in 2016 Hao Wu et al. presented a combined flap for coverage of combined fore-foot plantar and dorsal soft tissue defects. We used combined flaps in two cases and present our experience in this article.

Free vascularized medial femoral condyle periosteal flaps in the ankle and foot region: A narrative review.

OBJECTIVES: The objective of this study was to determine the role and reliability of the free medial femoral condyle (MFC) flap (MFCF) in demanding foot and ankle reconstruction procedures. MATERIALS AND METHODS: A search of the MEDLINE, PubMed, and Embase electronic databases was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines between January 2008 and September 2023. Articles concerning free MFC bone flaps for reconstruction of the foot and ankle regions were included. Outcomes of interest included flap failure, complications, union rate, time to union, and functional scores. RESULTS: Twenty studies involving 131 patients met the inclusion criteria. The most common clinical indications for the free MFCF were nonunion, avascular necrosis, and osteomyelitis. The most common sites of nonunion were tibiotalar arthrodesis (50%) and subtalar arthrodesis (33%). Overall, the bony union rate was 93.1%, with a mean time to union of 14.6±0.1 weeks. There were no flap failures reported. Postoperative complications were observed in 39 (29.7%) cases (e.g., delayed donor site wound healing, flap debulking, medial condyle osteonecrosis, and donor site numbness), with 21 (16%) patients requiring further operative intervention. No major donor or recipient site morbidity occurred, except for one case. CONCLUSION: Free MFCFs offer a versatile and dependable choice for cases of foot and ankle reconstruction, displaying favorable rates of bone fusion and acceptable complication rates. Existing literature indicates that MFC reconstruction in the foot and ankle is not associated with significant morbidity at the donor or recipient sites. The pooled data demonstrated a 93% success rate in achieving bone fusion in the foot and ankle region, supporting the view that it can be considered another option of treatment.

Double-Flap Elevation From the Ipsilateral Lower Extremity: The Anterior Approach to Fibula Osteo-Cutaneous Flap Elevation.

ABSTRACT: The free fibular flap has been elevated by a "lateral approach" from the posterior edge of the peroneal muscle for more than 40 years. However, in this approach, the surgical view is limited because flap elevation in mandibular reconstruction is performed simultaneously with tumor resection in the supine position, even when using positioning pillows. We herein propose an "anterior approach" as a new surgical method. We retrospectively investigated free fibular flap surgeries performed using the anterior approach, which consists of three anterior approaches, over a seven-year period. First, to avoid the course of the superficial peroneal nerve, the crural fascia was incised 1-2 cm posterior to the anterior edge of the peroneal muscle. The anterior edge of the peroneus muscle is detached from the anterior intermuscular septum. After performing osteotomies distal and proximal to the fibula, the interosseous membrane was incised from the anterior view. Pulling out the fibula to the anterior space between the anterior intermuscular septum and the peroneal muscle made the surgical field shallow. No postoperative superficial or deep peroneal nerve palsies were found in the 55 patients. Only one tourniquet was used in 31 of the 55 cases (56.4%), with an average of 95 min. Twenty-four patients (43.6%) required a second tourniquet 38 min after an interval. Only one tourniquet was used in 25 of the 30 (83.3%) cases in the last 3 years. Moreover, double flaps were used in 21 cases (38.2%), all of which involved ipsilateral ALT flaps. In 18 cases, double-flap elevation and prefabrication were successfully finished before the completion of tumor resection by otorhinolaryngologists.

Thrombotic Consequences of COVID-19 Infection on Microsurgical Reconstruction.

BACKGROUND: Evidence has shown increased morbidity and mortality for patients with COVID-19 infection within 7 weeks of surgery. However, no studies have specifically investigated the effects of COVID-19 in microsurgical outcomes. This study evaluated thrombotic and overall complications after free tissue transfer for a variety of indications in patients with and without previous COVID-19 infection. METHODS: A retrospective cohort study was performed in adult patients with or without a history of COVID-19 infection who underwent microsurgical reconstruction between 2017 and 2022. Patients with a history of COVID-19 infection were matched to controls based on age, gender, race, body mass index, history of diabetes, coronary artery disease, hypertension, Caprini score, tobacco use, and flap indication. RESULTS: From 2017 to 2022, 35 patients had a documented history of COVID-19. Matched case analysis determined a 4.8 times increased odds ratio of postoperative complications in the COVID-19 group compared with controls (p = 0.002). Significantly, more patients with COVID-19 experienced total or partial flap loss and anastomotic issues (COVID-19: 7/35, Control: 0/35; p < 0.001). There was no significant difference in incidence of VTE (COVID-19: 1/35, Control: 0/35; p = 0.493). Of note, 62.9% of the COVID-19 group were discharged on anticoagulants (versus 14.3% in the control group [p < 0.001]). CONCLUSION: COVID-19 has dire, long-lasting effects on virtually every organ system, chief among them, the microcirculation. Further studies are needed to fully determine the extent and influence of COVID-19 on complex procedures such as free tissue transfer and how to optimize the screening, workup, and postoperative care to guard against the associated thrombotic consequences.

Modern Oncologic Maxillary Reconstruction.

LEARNING OBJECTIVES: After studying this article, the participant should be able to: (1) Have a broad understanding of the oncological principles relating to cancers involving the maxilla. (2) Define anatomically the various types of maxillectomy defects and their associated morbidity. (3) Understand the goals and principles of maxillary reconstruction. (4) Demonstrate an understanding of the strengths, limitations, and alternative reconstructive options for the various types of maxillectomy defects. SUMMARY: Reconstruction of the maxilla following cancer resection has evolved over the past decade. Underpinned by advances in virtual surgery technology and an increased focus on dental rehabilitation, more sophisticated workflows using free bone flaps have become more commonplace. There are few reconstructions anywhere in the body that require the restoration of similarly intricate bone and soft-tissue relations with implications for both form and function, like the maxilla. Success demands careful anatomical definition of the defect, an understanding of the goals and principles of reconstruction, and the understanding of relative strengths and limitations of the various reconstructive options. Equally, as no one technique is without shortcomings and maxillary surgery can be associated with a significant complication profile, it is just as important to match the patient and oncologic context to the reconstruction. This article is intended to provide the reader with a broad overview of these core factors.

Interposition of Free Vascularized Fascia Into the Trapezial Resection Cavity for the Surgical Treatment of Trapeziometacarpal Osteoarthritis.

BACKROUND: Trapeziometacarpal osteoarthritis has been treated with interposition of autologous fascia into the trapezial resection cavity to prevent scaphometacarpal impingement with suboptimal results. Autologous fascia may undergo necrosis and gradual shrinkage due to avascularity. We propose vascularization of the interposed fascia using microvascular techniques as a new alternative to achieve a durable graft with sufficient soft tissue volume. PATIENTS AND METHODS: In this retrospective study, 11 surgeries for 8 patients (6 women, 2 men) (5 primary and 6 revision cases) were performed using vascularized fascial grafts from the anterolateral thigh for interposition in the trapezial resection cavity with microvascular anastomosis for revascularization. Subjective assessment included the short version of the Quick Disabilities of the Hand, Shoulder and Arm and patient related hand wrist evaluation scores. Objective assessment included strength and range of motion measurements. Radiographs were obtained preoperatively and at each follow-up visit. An MRI was done at a mean of 19 months postoperatively. RESULTS: The size of the harvested fascial grafts was 2 × 2-3 cm with a thickness of 1.5-2 cm. There were no postoperative complications apart from one seroma in the graft harvest site. The mean clinical and radiologic follow-up was 2 years and 8 months. The procedure provided pain relief PRWHE pain 32 (SD 13)-9 (SD 12), p < 0.0001, increased tip pinch strength 4 kg (SD3)-6 kg (SD2), p < 0.05, and improved overall function PRWHE 60 (SD28)-16 (SD21), p < 0.0001 and QuickDash 50 (SD21)-13 (SD17), p < 0.0001. Radiographs demonstrated maintenance of the scaphometacarpal space, while MRI scans showed the presence of mildly edematous interposed tissue within the resection cavity. CONCLUSIONS: Although technically demanding, vascularized fascia presents an attractive alternative for the treatment of trapeziometacarpal osteoarthritis. It may be particularly advantageous in complex cases requiring revision surgery and in young patients with high functional demands.

A comparison of postoperative outcomes based on recipient vessels in scalp free flap reconstruction: A systematic review and meta-analysis.

PURPOSE: The superficial temporal artery (STA) and facial artery (FA) are two commonly used recipient vessels when performing free tissue transfer to the head and neck. This meta-analysis compares the impact of recipient vessel location on free flap outcomes in scalp reconstruction. METHODS: A systematic review was conducted following PRISMA-P guidelines using six databases. Studies reporting free tissue transfer using the STA or FA as a recipient vessel for reconstructing scalp defects were included. Outcomes of interest included flap loss, partial flap necrosis, wound dehiscence, venous thrombosis, and infection rates. Quality evaluation was performed using ASPS criteria and the ROBINS-I tool. RESULTS: Of 3270 identified articles, 12 were included for final analysis. In total, 125 free flaps were identified (75 STA, 50 FA). Pooled analysis demonstrated an overall flap survival rate of 98.4% (STA 98.7% vs. FA 98.0%; p = .782). The mean defect size was significantly greater for flaps using the STA compared with the FA (223.7 ± 119.4 cm2 vs. 157.1 ± 96.5 cm2, p = .001). The FA group had a higher incidence of wound dehiscence than the STA group (14.0% vs. 1.3%, p = .005). However, meta-analysis demonstrated no significant difference in rates of wound dehiscence, flap loss, partial flap necrosis, venous congestion, or postoperative infection between groups. CONCLUSION: This is the first systematic review and meta-analysis to assess recipient vessel selection in scalp reconstruction. Our results do not support a single vessel as the superior choice in scalp reconstruction. Rather, these findings suggest that the decision between using the STA or FA is multifaceted, requiring a flexible approach that considers the individual characteristics of each case. Further research is needed to explore additional factors influencing recipient vessel selection, including defect location, radiation therapy, and prior head and neck surgery.

Propeller flap's assisted recipient site closure after free SCIP flap coverage of medial ankle defect: A case report.

Defects in the distal lower limbs are common in the field of orthoplastic reconstruction. The ankle area presents little subcutaneous tissue and is often affected by high-energy traumas and bone fractures. Wounds in this region are frequently associated with severe edema that might prevent primary closure. Due to its thinness and tension, the skin overlying both the medial and lateral malleoli is prone to necrosis, which can further lead to large soft tissue defects. Vessels, nerves, and tendons can easily become exposed. The reconstructive approach should aim to provide high-quality tissue that is durable enough to withstand the weight-bearing pressures and the friction from shoes, while remaining sufficiently elastic to conform to the shape of the ankle and to permit the foot movement. In this study, we describe the use of an additional propeller flap to reduce skin tension at the recipient site. A superficial circumflex iliac artery perforator (SCIP) flap was utilized to cover a defect below the medial malleolus. However, after flap inset, achieving a primary closure of the proximal wound without tension was not possible. During the dissection of the posterior tibial artery, perforator vessels were identified and preserved. The larger of these vessels was then used to vascularize a propeller flap, which was then rotated toward the defect to aid a tension-free closure. The postoperative course was uneventful. This case may provide a valuable insight into the challenges often faced during wound closure, even after flap inset. Since the flap itself may increase the width of the dissection area, the present case shows the importance of preserving perforator vessels during the proximal dissection since they can allow the harvest of an additional flap to achieve primary closure and further alleviate tension.

Comparison of instep and non-instep flap in the reconstruction of the weight-bearing portion of the forefoot and heel.

BACKGROUND: Instep flaps are commonly used for the reconstruction of weight-bearing areas of the foot. However, in cases of large defects or damage to the instep area, non-instep flaps such as reverse sural flaps (RSF) or free anterolateral thigh flaps (ALTF) can be employed. Previous studies have primarily focused on heel reconstruction when comparing different flaps, without considering the forefoot. This study aims to verify the clinical outcomes of these flaps and determine the appropriate donor site for weight-bearing areas of the foot including forefoot reconstruction. METHODS: In a retrospective study, 39 patients who had undergone flap reconstruction of weight-bearing area defects in the foot with a follow-up period of ≥1 year were included. The patients were categorized into two groups: Group A (n = 19) using instep flaps, and Group B (n = 20) using non-instep flap including RSFs and ALTFs. Surgical outcomes were assessed based on the success of the flap, the presence of partial necrosis, the number of additional surgeries, and complications related to the donor site. Clinical evaluation included visual analogue scale (VAS) and American Orthopedic Foot and Ankle Society (AOFAS) score, and the occurrence of ulcers. RESULTS: All flaps were successful, while partial necrosis occurred in one case in Group B. There were three reclosures after flap border debridement in both groups and one donor site debridement in Group A. The VAS scores during weight-bearing were 2.0 ± 1.1 and 2.2 ± 1.5 for Groups A and B, respectively (p = .716). The AOFAS scores were 52.8 ± 6.8 and 50.2 ± 12.7 for Groups A and B, respectively (p = .435). The occurrence of ulcers was 0.4 ± 0.9 times for Group A and 0.3 ± 0.7 times for Group B, with no significant difference between the two groups (p = .453). CONCLUSION: There was no difference in clinical outcomes between the types of flaps after reconstruction of the forefoot and hindfoot. Therefore, it is recommended to choose the appropriate flap based on factors such as the size of the defect, its location, and vascular status rather than the type of flap.

Single-staged revascularization and reconstruction after crush injury of the wrist and distal forearm: A protocolized approach.

BACKGROUND: Amputation of the wrist or distal forearm after high-energy trauma due to a crushing mechanism is associated with complex tissue defects, making repair, and reconstruction challenging. Given the difficulty of this type of salvage, patients unfortunately experience a high revision amputation rate. However, a higher quality of life has been reported in patients with successful reconstructions. Herein, we described a protocolized approach for revascularization and reconstruction for functional hand salvage after traumatic amputation from a crushing mechanism using an anterolateral thigh flap (ALT). METHODS: A retrospective review was performed between October 2016 and October 2023 for all patients who underwent single-stage emergent debridement, revascularization, and soft tissue coverage using the ALT after amputation at the level of the wrist or distal forearm secondary to high-energy crush injury. Charts were reviewed for the preoperative Mangled Extremity Salvage Score, intraoperative details including what structures were injured and the reconstructive method performed, and postoperative data such as follow-up duration, outcomes, and complications. RESULTS: Eleven patients met the inclusion criteria with an average age of 35.5 (21-49) years old. The average size of the skin soft tissue defects was 17.3 × 8 cm (range, length: 13-25 cm, width: 6-13 cm), and all cases had associated injury to the underlying bone, nerves, and blood vessels. The average size of the ALT flap used for reconstruction was 19.2 × 9.8 cm (range, length: 14-27 cm, width: 7-15 cm). All patients had survival of the replanted limb. One patient experienced partial flap necrosis that required secondary debridement and skin graft. Nine patients healed without requiring any additional debridement procedures. Patient follow-up averaged 24.6 (12-38) months. All patients achieved satisfactory functional recovery with Grade II to III of Chen's criteria. CONCLUSIONS: For patients with traumatic crush amputation to the wrist with surrounding soft tissue injury, thorough debridement, revascularization, and reconstruction of amputated limbs can be performed in a single stage using the ALT. A protocolized approach from two institutions is presented, demonstrating improved survival and reduced complications of the traumatized limb with improved long-term patient outcomes.

Free Fibular Osteocutaneous Flap Combined With Simultaneous Tendon Reconstruction for Midfoot Restoration After Myoepithelial Carcinoma Resection.

ABSTRACT: Myoepithelial carcinomas of soft tissue are rare, and most are malignant. The optimal treatment is surgical excision. The arches of the foot are a composite structure responsible for weight bearing and pressure distribution, so it is a vast challenge in reconstruction. We report a case of reconstruction of the midfoot with a free fibular bone flap and tendon graft. We review the literature to compare various options in foot reconstructions and sort out the outcomes of different bone flaps. The free fibula osteocutaneous flap is the superior choice for midfoot reconstruction owing to its sufficient length, strength, flexible skin paddles, easy-to-withstand osteotomy, and simultaneous tendon graft harvesting.

Limb Salvage Using Microsurgical Free Tissue Transfer in Severe Frostbite.

PURPOSE: Frostbite is often managed conservatively; however, in severe cases, microsurgical free tissue transfer is required for soft tissue coverage and limb salvage. Given its rarity, the techniques and outcomes of these cases are not well described. The purpose of this report is to present the largest case series, to date, of frostbite injuries requiring microsurgical reconstruction for limb salvage. METHODS: A single-center retrospective review was conducted of all patients who underwent free tissue transfer by a single surgeon from 2008 to 2022. Patients of all ages were included if they suffered a frostbite injury requiring free tissue transfer. Demographics, operative details, and surgical outcomes were recorded. RESULTS: Eight patients with frostbite injuries were included in the report. Patients had frostbite injuries either to the lower extremities (n = 4) or to both upper and lower extremities (n = 4). Sixteen free flaps were done in total including four paired chimeric and eight single free flaps. Flap recipient sites included knees (n = 5), foot/ankle (n = 3), dorsal hands (n = 2), and thumbs (n = 2). All 16 flaps survived. Five patients had complications: four with major complications requiring operative management and two with minor complications requiring conservative management. Mean follow-up time was 505.7 days (range 115-1564). All lower extremity reconstructions were able to weight-bear at an average of 125.2 days post-injury (range 87-164). CONCLUSIONS: This case series demonstrates that free tissue transfer is a robust option for soft tissue coverage and functional limb salvage in patients with severe frostbite injuries to both upper and lower extremities.

The free vastus lateralis-And conjoined vastus lateralis anterolateral thigh/tensor fascia lata flap for oncological chest wall reconstruction.

INTRODUCTION: A reconstructive option for extensive chest wall reconstruction is the free myocutaneous vastus lateralis muscle (VL) flap which can be performed in isolation or in conjunction with a fasciocutaneus anterolateral thigh (cVLALT) and/or myofasciocutaneous tensor fascia lata flap (cVLTFL). We aimed to directly compare the outcomes of these reconstructive options. METHODS: Patients who underwent oncological chest wall reconstruction with a free VL, cVLALT, or cVLTFL flap between February 2010 and 2022 were included in this retrospective study. Patient demographics, surgical characteristics, as well as medical and reconstructive outcomes, were evaluated. The operative outcomes between myocutaneous VL, cVLALT, and cVLTFL flap reconstructions were compared. RESULTS: A total of 41 patients underwent chest wall reconstruction with a free myocutaneous VL (n = 25; 61%), cVLALT (n = 14; 34%), or cVLTFL Three acute flap thromboses occurred in the entire cohort (3/41, 7%), with one myocutaneous VL flap failing because of recurrent venous thrombosis during the salvage procedure. Total flap necrosis was seen in two cases (5%; VL flap: n = 1; cVLALT flap: n = 1), and partial flap necrosis in one VL flap (1/25, 4%) and in the distal ALT portion of three cVLALT flaps (3/14, 21%). No significant difference was seen between isolated VL and conjoined VL flaps regarding the partial (p = .28) or total flap necrosis rate (p = .9). CONCLUSION: The free (conjoined) VL flap provides reliable outcomes for obliterating dead space achieving durable reconstruction of complex chest wall defects.

Long-term outcome of fibula flaps in complex limb reconstruction compared to alternative procedures, a median follow up of 41 months.

INTRODUCTION: Complex open long bone fractures present a multidisciplinary surgical challenge. Various treatment options are discussed with no consensus. Fibula flaps (FF) are frequently used in maxillofacial surgery, however their use in limb injuries is less common. With the tremendous improvement in microsurgery, orthoplastic surgery gained importance. Our retrospective study aims to assess the long-term results and the quality of life of the patients operated by FF for complex traumatic limb reconstruction. PATIENTS AND METHODS: We conducted an observational mono centric retrospective study from the year 2011 to the year 2021. Patients operated for complicated traumatic limb fractures using FF were included in the study. Not only long-term clinical results were evaluated, but also Patient-reported outcome measures (PROM). These included the Lower Extremity Functional Scale (LEFS), Quick Disabilities of the Arm, shoulder and hand (Qdash), and the Visual Analogue Scale (VAS). The statistical analysis was done using the R Software. RESULTS: Twenty patients were included in our study. 80% achieved complete union with no re fracture rate at a median follow-up of 41 months. All of the patients (n = 4) who underwent amputation were smokers (p = .09), were operated for lower limb fractures (p = .54), and were males (p = 1). The length of hospital stay was associated with an increased duration to complete bony union (p = .01, coefficient = 2.88). At the end of follow-up, the LEFS median score was 67 for the total population and 63.5 for the lower limb reconstructed sub group. CONCLUSION: VFF is an important tool in the armamentarium of orthoplastic surgeons. Encouraging long term functional and clinical outcomes were obtained in patients with complex traumatic limb fractures.
