Abstract: Simulation training has been growing in popularity, as a means to help supplement the training of surgical residents. The Newcastle Surgical Training Centre K-wiring course, a 1-day course designed for early-years surgical trainees, aims to teach essential skills in K-wire fixation for hand fractures. The course integrates lectures and hands-on practice with both simulated and cadaveric specimens, supported by a high faculty-to-delegate ratio. Despite minor limitations, such as the quality of initial hand simulators and the potential need for more radiographer support, the course provides substantial educational value and practical experience. Overall, authors found the Newcastle Surgical Training Centre K-wiring course to be a well-resourced and effective training opportunity for surgical trainees.

Abstract: The radial forearm free flap (RFFF) has emerged as a leading option for microvascular reconstruction of head and neck soft-tissue defects. Despite the favorable outcomes conferred by RFFFs, complications such as skin graft loss and tendon exposure can occur. We present the case of a 77-year-old man who underwent RFFF reconstruction after excision of squamous cell carcinoma from the head and neck. The patient subsequently developed flexor tenosynovitis, septic arthritis of the wrist, and osteomyelitis of several carpal bones as a direct result of partial skin graft loss and prolonged tendon exposure at the donor site. To the best of our knowledge, this is the first reported case of this specific complication. Review of the literature reveals the need for continued research into RFFF donor site complications to mitigate the incidence of significant morbidity.

Background: Among patients with critical limb ischemia and tissue loss, revascularization is an essential component for limb salvage. Local flaps of the foot and ankle remain a versatile tool in reconstructive limb salvage but is dependent on adequate arterial flow. In patients with arterial occlusive disease requiring revascularization, there is a lack of evidence in the current literature investigating on the necessity of direct arterial flow to the respective angiosome for local flaps reconstruction. Our study thereby compares the outcomes of direct (DR) and indirect (IR) revascularization for local flap success.

Methods: Patients who received endovascular revascularization (ER) prior to local flap reconstruction for chronic wounds in the foot and ankle were retrospectively reviewed. IR was performed in patients where DR could not be performed. DR was defined as an intervention on the same pedicle used for the local flap. IR was defined as an intervention performed on a different angiosome than the pedicle used for the local flap. Patient demographics, Charlson Comorbidity Index (CCI), angiographic details, postoperative complications, and long-term outcomes were collected.

Results: A total of 33 patients underwent 43 local flap reconstruction with preoperative ER: 58.1% (n = 25) received DR and 41.2% (n = 18) received IR. Patients had a mean CCI of 6.7 ± 1.8, with a high prevalence of diabetes mellitus (93.9%), peripheral arterial disease (90.9%), and end-stage renal disease (33.3%) with no significant differences between groups. In the immediate postoperative period (postoperative day 0 to 12), there were no significant differences in immediate flap success (DR: 100% vs IR: 88.9%, P = 0.169) or partial flap necrosis between (DR: 0.0% vs IR: 16.7%, P = 0.066). Rates of major complications from infection (DR: 28.2% vs IR: 22.2%, P = 0.736), ischemia (DR: 4.0% vs IR: 11.1%, P = 0.562), or dehiscence (DR: 8.0% vs IR: 16.7%, P = 0.634) requiring reoperation were similar between 2 groups. Overall limb salvage rate was 84.9%, and comparable between groups (DR: 78.6% vs IR: 89.5%, P = 0.628).

Conclusions: DR and IR achieve similar rates of limb salvage and flap success after local flap reconstruction. A multidisciplinary vasculo-plastic approach that incorporates preoperative arteriogram and revascularization should be utilized for this highly comorbid patient population to achieve optimal success and limb salvage.

Abstract: Indocyanine green (ICG) is a water-soluble green substance that is detectable through infrared cameras and emits greenish light. Approved for medical use in the 1950s, ICG has gained prominence as a real-time visualization tool. Widely recognized as a generally safe substance, ICG is applied in diverse fields. Despite its prevalent use without significant safety concerns, we report a case of anaphylactic shock due to ICG to reflect on its potential risk.A 46-year-old woman with phyllodes tumor of the breast came to our clinic. She had no significant medical history except dog hair allergy. She underwent nipple-sparing mastectomy, and we planned reconstruction with a deep inferior epigastric perforator free flap. Intraoperatively, we injected ICG to visualize the perfusion area of the abdominal flap. Immediately after injection, her blood pressure dropped to 39/32 from 124/66. Anaphylaxis management included injection of epinephrine, norepinephrine, and steroid. With proper management, her vital signs recovered to normal ranges and the operation proceeded. After discharge, the patient developed no flap-related or internal medical complications.Despite the widely known safety of ICG, it carries a risk of life-threatening adverse effects. Surgeons should be aware that, although rare, these events can occur in their operations.

Background: While there is mounting evidence that closed suction drains are not necessary, there is a paucity of literature to demonstrate that drains are harmful after breast reduction. The purpose of this study was to investigate the effect of drains on postoperative seroma, hematoma, and infection, as well as elucidate any risk factors that may be implicated in the development of these complications.

Methods: A retrospective cohort study was conducted of all reduction mammaplasty procedures at our university medical center between 2010-2020. Pedicle type, skin incision, drain utilization, breast excision mass, sternal notch to nipple distance, and inframammary fold to nipple distance were analyzed with postoperative outcomes including hematoma, seroma, infection, dehiscence, nipple necrosis, and fat necrosis.

Results: This study included 944 female patients undergoing reduction mammaplasty. Median age was 39.0 years, median body mass index was 31.9 kg/m2, and median breast mass resected was 742 grams per side. Drain utilization did not significantly reduce postoperative hematoma (P = 0.196), seroma (P = 0.185), nipple necrosis (P = 0.511), or fat necrosis (P = 0.113), but drain utilization significantly increased postoperative surgical site infection (P = 0.011). Patients with breast mass removed over 1500 g had significantly higher risk of hematoma (P = 0.002), fat necrosis (P < 0.001), and nipple necrosis (P < 0.001) compared to patients with less than 1500 g removed. In patients with greater than 1500 g resected, drain utilization did not significantly decrease risk of hematoma (P = 0.086) or seroma (P = 0.497).

Conclusions: Breast reduction greater than 1500 g per side significantly increased risk of hematoma, nipple necrosis, and fat necrosis. Drain utilization did not demonstrate any advantageous effects, rather it increased risk of infection. Future multicenter study will be needed to confirm these findings across different patient referral networks and practice patterns.

Background: Red breast syndrome (RBS) has been noted in past literature as a possible complication of implant-based breast reconstruction (IBBR) with the use of acellular dermal matrices (ADMs). Since its first appearance in 2009, RBS has drawn growing medical attention with reported incidence ranging from 7%-9%. There has been a noted decrease in the emergence of RBS despite its inclusion among the analyzed complications in a number of studies. This systematic review aims to evaluate the trend in reported RBS incidence over time and appropriately determine an accurate incidence of RBS from reported literature since the emergence of the phenomena.

Methods: A systematic literature review was performed in July 2023 that analyzed the incidence of RBS among retrospective cohort studies on complication rates of IBBR with ADM. Patient demographics, RBS incidence rates, and all-cause complications were captured. The review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines and Methodological Index for Nonrandomized Studies criteria was used to assess study quality.

Results: From 2009 to 2023, a total of 48 studies (n = 6251) met inclusion criteria of which 35 studies from 2017 to 2023 were not already included in a prior systematic review (n = 5246). The mean incidence of RBS in the unreported studies was 2.88% with a weighted mean of 3.22%. Analysis of the trend in RBS over time shows an increasing reported incidence rate from 2009 with a peak in incidence between 2016 and 2017, followed by a steady decline through 2022. Twenty-six of the studies were published from 2016 to 2019.

Conclusions: The incidence of RBS among prior studies and systematic reviews has fluctuated significantly since its initial emergence in 2009. Reported incidence rates have been on the decline since 2018 with a true weighted incidence of 3.22% from analysis of recent reported studies. Potential causes for the decline in incidence include practice changes in ADM preparation, changes in the ADM brand used for IBBR, and improved categorization of RBS compared to cellulitis/infection. Despite more robust criteria for diagnosis, no consensus for management has yet been established.

Purpose: Clavicular nonunion is an uncommon complication with a significant impact on quality of life and can be difficult to manage. In recalcitrant cases, or situations unfavorable for take of nonvascularized grafts, vascularized osseous reconstruction may be utilized. Several donor sites for such flaps have been described, with each associated with unique benefits and drawbacks.

Methods: A systematic review utilizing MEDLINE and Embase databases was performed for cases of vascularized bone reconstruction for clavicle nonunion.

Results: Twenty-six papers met inclusion, comprising 67 patients. Mean age was 43.1 years, across 32 male and 35 female patients. Mean period of nonunion was 43.2 months in the fibular group, 42.0 months in the medial femoral condyle (MFC), and 12 months in the rib flap group. Patients had undergone a mean of 2.67 prior operations at the time of vascularized osseous flap; a proportion of patients had undergone prior locoregional radiotherapy (9/26) or been complicated by infection (12/22). Radiological union was achieved in 95.2% (20/21) of fibular flaps, 95.6% (25/27) of MFC flaps, and 66.7% (2/3) of rib flaps. Mean time to union was 10.6 months for the fibular group, 7.8 months for the MFCs, and 4.0 months for the rib flaps. Complications occurred in 55.6% (20/36) of patients having fibular flaps, 26.1% (6/23) of MFC flaps, and 50% (2/4) of rib flaps.

Conclusions: All osseous flaps yielded similar and consistent rates of union when used to reconstruct defects of the clavicle. Higher complication rates, particularly donor site morbidity, were noted with fibula and rib flaps when compared to the MFC.

Background: Situs inversus is a congenital malformation that occurs in one or multiple organs simultaneously and can be accompanied by malformations in other body parts. We analyzed the prevalence and phenotype of patients with situs inversus and comorbidities associated with other plastic surgery-related malformations to enhance the knowledge of its related disorders and facilitate treatment.

Methods: We recruited patients with situs inversus who were seen at our institution from February 2015 to July 2023. They underwent ultrasound and physical examinations to investigate deformity in other body parts. Fisher's exact test was used to analyze the laterality between hemifacial microsomia and situs inversus type.

Results: All 14 patients with situs inversus had plastic surgery-related malformations-three congenital and three developmental. Nine (65%) patients had hemifacial microsomia (right side, n = 8; bilateral, n = 1). The laterality of hemifacial microsomia was associated with the situs inversus type, with a significant difference ( P < 0.05), and hemifacial microsomia occurred ipsilaterally in patients with right-sided hearts.

Conclusions: Early situs inversus diagnosis is clinically important for patients and plastic surgeons. Further studies on anomalies associated with situs inversus will improve our understanding of their etiology.

Background: Complex lower extremity defects are difficult to cover and often require multiple free tissue transfers. Chimeric anterolateral thigh free flaps (ALTF) and peroneal artery perforator free flaps (PAPF) have been designed specifically as an alternative for reconstruction with arterial end-to-side (ETS) anastomosis. We aimed to assess our institutional experience with this technique and to define its role in complex lower extremity reconstruction.

Methods: From July 2012 to March 2023, 27 patients with complex lower extremity defects underwent reconstruction with chimeric ALTF or PAPF. Patients were performed with retrograde flaps for repairing refractory wounds of tibia plateau fracture and antegrade flaps for distal 2/3 tibia and beyond. Demographic, clinical, and follow-up data on the patients were recorded with a special focus on complication profiles during a follow-up of 6 to 60 months.

Results: The mean defect size measured 121.1 ± 215.1 cm 2 , and the chimeric ALTF or PAPF flaps measured 143.9 ± 177.8 cm 2 . One patient lost the first free flap but successfully had a chimeric PAPF then. Three patients suffered partial free flap loss, and another 3 had minor complications. All 6 survived after an additional exploration, wound dressing, or antibiotics treatment. The retrograde flaps achieved similar blood flow to the antegrade flaps. Patients are all satisfied with functional and aesthetic outcomes.

Conclusions: Given the incidence of complications, utilizing chimeric ALTF and PAPF either with retrograde or antegrade flow based on arterial ETS anastomosis is a reliable surgical option for complex lower extremity reconstructions.
