Abstract
BACKGROUND The BYCROSS™ device is a novel device intended for use in atherectomy of the peripheral arterial disease (PAD). With the BYCROSS™ atherectomy system, also prolonged calcifying lesions can be treated in a minimally invasive manner, which was previously reserved for bypass surgery. The aim of this study is to collect additional clinical data on safety and performance of the BYCROSS™ from patients undergoing revascularization of severely stenotic or occluded peripheral arterial vessels with the BYCROSS™. METHODS AND DESIGN This is an investigator-initiated national prospective multicenter observational study in patients with PAD. Sixty patients (20 per center) with PAD with stenosis higher than 80% or complete occlusion (de novo or recurrent stenosis) of vessels below the aortic bifurcation (min 3 mm vessel diameter) will be recruited. Three vascular surgery centers are participating in the study. The primary efficacy endpoint is procedural success, defined as passage of the occlusion through the BYCROSS device, and safety outcomes, explicated as freedom from device-related serious adverse events (SADEs). Secondary endpoints include primary and secondary patency rates, change in Rutherford classification, and freedom from amputation at 3 and 12 months. DISCUSSION The BYCROSS atherectomy system may be a novel device for the minimally invasive treatment of prolonged calcified lesions previously reserved for bypass surgery. This national prospective multicenter observational study could represent another step in demonstrating the efficancy and safety of this device for treatment of PAD.

Abstract
Background Limb salvage surgery in osteosarcoma requires a multidisciplinary team of experts, due to which research interest has remained limited globally. This article analyzes research trends over 15 years from 2007 to 2022. Materials and Methods Publications on limb salvage surgery in osteosarcoma were retrieved using the Web of Science. Bibliometric analysis of the publication metadata was done using R software. VOS viewer software was used to analyze the bibliographic coupling, co-citation, co-authorship, and co-occurrence to report the current trends in global research on limb salvage surgery in osteosarcoma. Results A total of 693 articles were retrieved. On applying the inclusion and exclusion criteria, a publication metadata of 276 articles was analyzed using the methodology mentioned. Annual scientific production on the subject has shown a steady rising trend globally. China has the highest number of publications on the topic; however, the USA has the highest citations globally. The Journal "Clinical Orthopedics and Related Research" remains the pioneer in the topic with the highest number of publications and H index among all journals. Most of the research interest is generated in the developed countries of the USA, Europe, and China. Keyword analysis suggested 4 clusters of surgical reconstruction, Survival, Chemotherapy, and general management related. Newer keywords such as biological reconstructions, allograft, metastases, cell, and chemotherapy suggest future research topics in the field. Conclusion Research interest in limb salvage surgery in osteosarcoma continues to grow with the introduction of concepts such as biological reconstructions and allografts. However, for more inclusive research on the topic, research interest must also be encouraged in underdeveloped and developing countries.

Abstract
Crush injury is one of the most challenging decisions for a surgeon to decide whether to proceed with an amputation or salvage a limb. We presented a 24-year-old man who complained of having suffered a crushed thigh 12 h before admission to the hospital. The patient was driving a truck and hit the iron bridge barrier, which penetrated his left thigh. The patient's left foot was cold, pallid, and pulseless, with a MESS score of 11. The femur x-ray showed a displaced fracture of the left femur associated with a 15 cm bone defect. The patient was diagnosed with a crush injury on the left femur with vascular compromise. We performed a proximal femoral megaprosthesis for a crush injury on the lower extremity, After the sixth year's follow-up, it shows a good outcome and increased quality of life for this patient. In addition, there was an improvement in the Harris Hip Score and EQ5D score. Megaprosthesis used to treat a crush injury revealed good functional outcomes despite the MESS score of 11. A multi-professional approach to the patient is essential for decision-making regarding limb salvage rather than the use of a score.

Abstract
OBJECTIVE For patients with soft tissue sarcoma, surgical resection is a key element of curative therapy. Surgery is performed as a wide resection with microscopically negative margins (R0 resection) and as limb-sparing procedure whenever possible to preserve maximum function. INDICATIONS Soft tissue sarcoma, metastases. CONTRAINDICATIONS Extensive disease with major neurovascular involvement, placement of biopsy tract necessitates extensive resection, palliative care. SURGICAL TECHNIQUE Extended deltopectoral approach. Release of pectoralis major and minor tendons. Vascular and neurologic exploration, identification of the axillary vessels and brachial plexus, placing of loops around major structures. Mobilization of these structures to achieve adequate exposure. Clipping of vessels entering the tumor. Tumor resection, suture marking for histological analysis. Soft tissue reconstruction by transosseous reinsertion of the pectoralis minor to the coracoid process. Drill channel placement, transosseous refixation of the pectoralis major to the humerus. POSTOPERATIVE MANAGEMENT Shoulder abduction brace for 6 weeks, passive mobilization for 6-12 weeks followed by active mobilization. Compression sleeve. Oncological follow-up. RESULTS Between 2017 and 2022, wide resection was performed in 6 consecutive cases including 4 primary soft tissue sarcomas and 2 metastases. Primary R0 resection was achieved in 100%. Mean follow-up was 22.5 months (3-60 months). There were no local recurrences. Mean active shoulder abduction was 135.0 ± 41.4° (90-180°). Neurological deficits were not observed. Mean subjective shoulder function was 80.0 ± 21.0% (50-100%). The mean Musculoskeletal Tumor Society (MSTS) score was 89.5% (32-100%), indicating good functional outcome in the study cohort.

Abstract
Recurrent parosteal sarcomas with vascular involvement are rare and present unique challenges in their diagnosis and management. We report the case of a 21-year-old woman with parosteal osteosarcoma of the left distal femur, encasing the popliteal vessels. En bloc transarticular resection of the distal femur and popliteal vessels was performed, followed by reconstruction using a modular prosthesis and a saphenous vein autograft for both the artery and vein. On the 1st postoperative day, the patient developed an arterial thrombus requiring reintervention with a jump polytetrafluoroethylene (PTFE) graft. Histopathology confirmed parosteal osteosarcoma. After a disease-free survival of 41 months, the patient experienced local recurrence involving the PTFE graft, leading to graft compression, erosion, and subsequent thrombosis. Despite these complications, limb salvage was possible due to adequate collateral blood supply. This case highlights the feasibility of limb salvage surgery in select cases of parosteal osteosarcoma with vascular involvement.

Abstract
OBJECTIVE Free tissue transfer is a powerful reconstructive method for patients with substantial diabetic foot ulcers. This study aimed to perform an updated systematic review and meta-analysis investigating the flap characteristics, concurrent revascularisation rates, complications, and outcomes associated with free tissue transfer in diabetic foot ulcers. METHODS Two reviewers performed a systematic review of various databases since their inception, with no language restriction. Only data for free tissue transfer in non-traumatic diabetic foot ulcer patients were extracted from included studies where a heterogeneous population was studied. Outcome data were pooled using random effects meta-analysis for binomial data. RESULTS Of 632 studies identified, 67 studies encompassing 1 846 patients and 1 871 free flaps were included. A median of 18 patients [IQR 9, 37] per study, with a median age of 58.5 years [56, 63], were followed up for a median of 15 months [7, 25]. Most studies had serious risk of bias (n = 47 studies, 70%); sixteen (24%) had moderate risk of bias; and four (6%) had low risk of bias. The proportion of patients who underwent revascularisation was 75% (95% CI 60 - 87%; n = 36 studies) with a median time of 8 days between procedures. The pooled complete flap survival, major amputation, and ambulation rates were 88% (85 - 92%, n = 49 studies), 10% (7 - 14%, n = 50 studies), and 87% (80 - 92%, n = 36 studies), respectively. Death at individual study follow up was 6% (3 - 10%, n = 26 studies). The overall certainty of evidence was very low. CONCLUSION Free tissue transfer may be a useful treatment modality for recalcitrant diabetic foot ulcers in selected patients. Future studies should investigate long term functional outcomes and aim to develop patient selection algorithms to select the most suitable candidates for this procedure.

Injury 2023; 54:111003. [PMID: 37652779 DOI: 10.1016/j.injury.2023.111003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Revised: 08/06/2023] [Accepted: 08/15/2023] [Indexed: 09/02/2023]
Abstract
BACKGROUND The purpose of this study is to assess the diagnostic utility of the Mangled Extremity Severity Score (MESS) in the prediction of amputation after a major earthquake, and its utility in disaster triage. METHODS Study results were presented from a tertiary hospital in Diyarbakır, which was affected by the earthquake but served as a transport hub for other cities in the region affected by the earthquake. MESS was calculated and its diagnostic value is analyzed in predicting amputations. MESS scores were divided into low risk, intermediate risk, and high risk groups by the researchers based on their diagnostic value analysis. RESULTS 79 patients were included in the study. Based on the outcome of amputation or salvage, patients were divided into two groups. 24.1% (n = 19) of the patients had amputations. Both gender and mean age did not differ statistically significantly between the groups (p > 0.05). Compared with the salvage group, the amputation group had a significantly longer prehospital stay and higher rate of vascular injury and higher median MESS (p = 0.007, p < 0.001, p < 0.001; respectively). Based on MESS scores, amputation outcomes were predicted with an accuracy of 0.889 (95% CI 0.798-0.949). Those with a MESS score below 9 were considered low risk (sensitivity = 100%) whereas those with a MESS score above 12 were considered high risk (specificity = 98.33%). CONCLUSION In transport centers, MESS may be useful for surgical triage of earthquake-induced limb crush injuries.

Abstract
PURPOSE Bone tumors around the elbow are rare, with frequently delayed diagnosis. The current study aimed to assess the functional and oncological outcomes of limb salvage surgery for primary benign aggressive or malignant bone tumors around the elbow. METHODS We conducted a retrospective review of patients with primary aggressive benign and malignant bone tumors around the elbow treated with limb salvage surgery between 1995 and 2020 at a single musculoskeletal oncology center. The minimum follow-up period was 24 months. Functional results were assessed using the Musculoskeletal Tumor Society (MSTS) scoring system at the last follow-up visit. Local recurrence, chest metastasis, and complications were recorded. RESULTS This study included 30 patients, 19 males and 11 females, with a mean age of 25.4 ± 14.2 years. The tumor location was the distal humerus (n = 21), proximal radius (n = 5), and proximal ulna (n = 4). Reconstruction was done by elbow fusion using fibular graft (n = 10), mobile endoprosthesis (n = 9), excision arthroplasty (n = 7), and extracorporeal freezing and reimplantation (n = 4). The mean follow-up period was 36.2 ± 21.3 months. The median follow-up MSTS score was 27 [Interquartile range (IQR): 26-30]. Skeletally immature patients had a significantly higher MSTS score. The rate of postoperative complications was 26.7%. CONCLUSION Limb salvage surgery with different reconstructive options for benign aggressive and malignant bone tumors around the elbow can achieve good functional and oncological outcomes.

Abstract
BACKGROUND Popliteal artery aneurysms (PAAs) need urgent treatment in case of acute thrombosis, distal embolization, or rupture. Few data are available in the literature about the treatment results in these scenarios. The aim of the present study was to evaluate an 11-year multicenter experience in the urgent treatment of PAAs. METHODS All symptomatic PAAs surgically treated in two vascular centers between 2010 and 2021 were retrospectively analyzed. In the postoperative period periodical clinical and Duplex-Ultrasound evaluation were performed. The evaluated endpoint was the outcome of urgent PAAs treatment according to their clinical presentation. Statistical analysis was performed by Kaplan-Meier log-rank evaluation and multivariable Cox regression tests. RESULTS Sixty-six PAAs needed an urgent repair. Twelve (18%) patients had a PAA rupture and 54 (82%) had an acute limb ischemia (ALI) due to either distal embolization or acute thrombosis. Patients with ALI underwent bypass surgery in 51 (95%) cases, which was associated with preoperative thrombolysis in 18 (31%) cases. A primary major amputation was performed in 3 (5%) cases. The mean follow-up was 52 ± 21 months with an overall 5-year limb salvage of 83 ± 6%. Limb salvage was influenced only by the number of patent tibial arteries (pTA) [5-years limb salvage 0%, 86 ± 10%, 92 ± 8% and 100% in case of 0, 1, 2 or 3 pTA, respectively (P = .001)]. An independent association of number of pTA and limb loss was found [hazard ratio (HR): 0.14 (95% confidence interval (CI) 0.03-0.6), P = .001]. Overall 5-year survival was 71 ± 7%. Ruptured PAAs were associated with lower 5-year survival compared with the ALI group (48 ± 2% vs. 79 ± 7%, P = .001). The number of pTA (33 ± 20%, 65 ± 10%, 84 ± 10% and 80 ± 10% for 0, 1, 2 and 3 pTA, respectively, P = .001) and the thrombolysis (94 ± 6% vs. 62 ± 10%, P = .03) were associated with higher survival in patients with ALI. There was an independent association of number of pTA and long-term survival [HR 0.15 (95% CI 0.03-0.8), P = .03]. CONCLUSIONS PAA rupture is the cause of urgent PAA treatment in almost one fifth of cases, and it is associated with lower long-term survival. ALI can benefit from thrombolysis, and long-term limb salvage and survival are associated with the number of pTA.

BACKGROUND Traumatic hemipelvectomies are rare and serious injuries. The surgical management was described in several case studies, with primary amputation often performed to save the patient's life. METHODS We report of two survivors with complete traumatic hemipelvectomy resulting in ischemia and paralyzed lower extremity. Due to modern emergency medicine and reconstructive surgery, limb salvage could be attained. Long-term outcome with quality of life was assessed one year after the initial accident. RESULTS AND CONCLUSIONS The patients were able to mobilize themselves and live an independent life. The extremities remained without function and sensation. Urinary continence and sexual function were present and the colostomy could be relocated in both patients. Both patients support limb salvage, even having difficulties and follow-up treatments. Concomitant cases are required to consolidate the findings. LEVEL OF EVIDENCE IV.

Abstract
This report presents the case of a 25-year-old male with an infected tibial diaphyseal nonunion caused by a bone transport procedure carried out to treat an open fracture the patient had sustained 10 years before referral to our hospital. After an initial radical debridement, a bone defect was created, which was subsequently obliterated by placement of an antibiotic-impregnated cement spacer and Stimulan beads and covered by an anterolateral thigh flap. As the patient refused to wear an external fixator and his osseous biology was not amenable to a Masquelet procedure, a decision was made to apply the Capanna technique as soon as the infection healed. The second debridement resulted in a 12-cm-long bone defect that was filled with a tibial allograft and a vascularized fibular graft. At six months, the patient had regained full knee function and was able to bear his full weight, without pain or the need of support equipment. At one year, the bone had healed completely, the infection had subsided and the patient was able to resume his everyday activities. Although the Capanna technique was initially developed to reinforce reconstructions at risk of fracture or nonunion as a result of chemotherapy, its use in post-traumatic cases has been shown to be successful in a selected group of patents. Our study demonstrated that increasing the stability of a reconstruction with an allograft can accelerate the time to heal, and that using a vascularized fibular graft can enhance incorporation of the whole construct. It can be concluded that the Capanna technique is a valid treatment option for managing infected segmental bone defects in selected patients.

Abstract
OBJECTIVE The use of basilic vein in iliofemoral revascularizations was previously described in the literature as an autologous option for the treatment of vascular prosthesis infection and as a primary conduit in patients at high risk of infectious surgical complications. However, the publications available include several different indications and are limited to case reports. Therefore, the aim of this study was to evaluate the outcomes of the use of arm veins as a safe and effective autologous alternative for iliofemoral reconstruction in patients with chronic limb-threatening ischemia (CLTI) and at high risk of prosthesis infection. METHODS We performed a multicenter, retrospective cohort study with 53 consecutive iliofemoral bypasses using arm veins as an alternative conduit. The procedures were performed between November 2013 and November 2021, exclusively for patients with CLTI classified as TASC aortoiliac C or D with increased risk of postoperative surgical infection. Demographic, clinical variables, and outcomes were collected from a prospective database. Main endpoints were amputation-free survival (AFS) and major adverse cardiovascular events. Secondary endpoints included primary and secondary patencies and overall survival. Cox regression analysis was used to identify the predictors of AFS. Postoperative surgical complications and 30-day mortality were also assessed. RESULTS The mean age was 64.2 ± 8.4 years, with a predominance of male gender. The median follow-up period was 615 days. All patients had CLTI, with a predominance of tissue loss (n = 51; 96.2%) and a median ankle-brachial index of 0.28. The basilic vein was utilized in most procedures (69.8%). Thirty-day major adverse cardiovascular events occurred in five cases (9.4%), and the 30-day mortality rate was 3.8%. The AFS, primary patency, secondary patency, and overall survival in 720 days were 71%, 72%, 89%, and 75%, respectively. Cox regression analysis revealed no association between the variables analyzed for AFS. There was no graft late infection nor pseudoaneurysmal degeneration. CONCLUSIONS Iliofemoral bypass using arm veins as an autologous conduit proved to be an effective and safe procedure with low incidence of postoperative cardiovascular complications and high rates of AFS in patients with CLTI. Also, this suggests that arm veins can be an interesting and suitable autologous alternative conduit for iliofemoral reconstructions, especially in cases in which a prosthesis should be avoided or when it is not available.

Abstract
Soft tissue and bone defects that occur consequence of high-energy trauma are serious and challenging problems. The aim of this retrospective cohort study is to show that the artificial deformity creation (ADCr) method allows the closure of soft-tissue defects, avoids amputation, and can facilitate the reconstruction of bone defects and restore limb length. Patients and methods Twenty-six adult patients (age range 20-81 years) with soft tissue defects of the lower limb were treated at the Riga East University Hospital from 2018 to 2021. All patients were treated using the ADCr method which is the technique of establishing an interim deformity for resolving tissue loss. The lower extremity functional scale (LEFS) and application of methods of ilizarov (ASAMI) criteria were used for the evaluation of bone healing and lower extremity function. Results Complete union was achieved in all cases. The functional evaluation showed that most patients could achieve excellent and good results and return to activities of daily living. The functional result was poor in one case of a multi-fragmentary distal tibial articular fracture for which an ankle fusion was performed. Final union in this case was achieved with some residual deformity. Conclusion The method of ADCr is an effective surgical technique in cases of severe tibial injuries with concomitant loss of bone and soft tissues. This method could be used in cases when either a plastic or microsurgeon is not available or for instances when closing the defect with a flap is either impossible or contraindicated. Excellent and good functional results are possible without severe complications. How to cite this article Plotnikovs K, Kamenska J, Movcans J, et al.

Abstract
An increasing proportion of patients with chronic limb-threatening ischemia are older and have multiple comorbidities, including diabetes and renal failure. For those who are not candidates for a surgical bypass, this set of patients presents a challenge to vascular surgeons and interventionalists owing to the complex below-the-knee and increasingly below-the-ankle disease pattern that can fail traditional approaches for endovascular intervention. Two techniques, the retrograde pedal access and the pedal-plantar loop technique, can be useful in these settings and in skilled hands can be used safely, with a high technical success rate. In patients with chronic limb-threatening ischemia who are not candidates for a single-segment saphenous vein bypass, the retrograde pedal access technique can be used not only in the setting of failed antegrade treatment, but also primarily when faced with a difficult groin or as an adjunct during a planned antegrade-retrograde intervention. The pedal plantar loop technique allows for retrograde access to tibial vessels without retrograde vessel puncture and additionally offers the ability to treat the pedal-plantar arch, which may have added benefit in wound healing. We describe the tips and tricks for these two techniques used in our limb salvage practice.

Abstract
OBJECTIVE Long-term outcomes in civilian trauma patients requiring upper or lower extremity revascularization is poorly studied secondary to limitations of certain large databases and the nature of the patients in this specific vascular subset. This study reports on the experience and outcomes of a Level 1 trauma center that serves both an urban and a large rural population over a 20-year period to identify bypass outcomes and surveillance protocols. METHODS Database of a single vascular group at an academic center was queried for trauma patients requiring upper or lower extremity revascularization between January 1, 2002, and June 30, 2022. Patient demographics, indications, operative details, operative mortality, 30-day nonoperative morbidity, revisions, subsequent major amputations, and follow-up data were analyzed. RESULTS A total of 223 revascularizations were performed, 161 (72%) lower and 62 (28%) upper extremities. One hundred sixty-seven patients (74.9%) were male, with a mean age of 39 years (range, 3-89 years). Comorbidities included hypertension (n = 34; 15.3%), diabetes (n = 6; 2.7%), and tobacco use (n = 40; 17.9%). Mean follow-up time was 23 months (range, 1-234 months), with 90 patients (40.4%) lost to follow-up. Mechanisms included blunt trauma (n = 106; 47.5%), penetrating trauma (n = 83; 37.2%), and operative trauma (n = 34; 15.3%). Bypass conduit was reversed vein (n= 171; 76.7%), prosthetic (n = 34; 15.2%), and orthograde vein (n = 11; 4.9%). Bypass inflow artery was superficial femoral (n = 66; 41.0%), above-knee popliteal (n = 28; 17.4%), and common femoral (n = 20; 12.4%) in the lower extremity, and brachial (n = 41; 66.1%), axillary (n = 10; 16.1%), and radial (n = 6; 9.7%) in the upper extremity. Lower extremity outflow artery was posterior tibial (n = 47; 29.2%), below-knee popliteal (n = 41; 25.5%), superficial femoral (n = 16; 9.9%), dorsalis pedis (n = 10; 6.2%), common femoral (n = 9; 5.6%), and above-knee popliteal (n = 10; 6.2%). Upper extremity outflow artery was brachial (n = 34; 54.8%), radial (n = 13; 21.0%), and ulnar (n = 13; 21.0%). Total operative mortality was nine patients (4.0%), all involving lower extremity revascularization. Thirty-day non-fatal complications included immediate bypass occlusion (n = 11; 4.9%), wound infection (n = 8; 3.6%), graft infection (n = 4; 1.8%), and lymphocele/seroma (n = 7; 3.1%). All major amputations (n = 13; 5.8%) were early and in the lower extremity bypass group. Late revisions in the lower and upper extremity groups were 14 (8.7%) and four (6.4%), respectively. CONCLUSIONS Revascularization for extremity trauma can be performed with excellent limb salvage rates and has demonstrated long-term durability with low limb loss and bypass revision rates. The poor compliance with long-term surveillance is concerning and may require adjustment in patient retention protocols; however, emergent returns for bypass failure are extremely low in our experience.

Surgery at specialised sarcoma centres improves patient outcomes - A systematic review by the Australia and New Zealand sarcoma association clinical practice guidelines working party. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:106951. [PMID: 37301636 DOI: 10.1016/j.ejso.2023.06.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 06/02/2023] [Accepted: 06/05/2023] [Indexed: 06/12/2023]
Abstract
BACKGROUND Optimal management of sarcoma requires multidisciplinary team input throughout the process of diagnosis, treatment and follow up. This systematic review aimed to evaluate the impact of surgery performed at specialised sarcoma centres on outcomes. METHODS A systematic review was conducted using the population, intervention, comparison and outcome (PICO) model. Medline, Embase, Cochrane Central databases were queried for publications that evaluated the local control, limb salvage rate, 30-day and 90-day surgical mortality, and overall survival in patients undergoing surgery in a specialist sarcoma centre compared with non-specialist centre. Each study was screened by two independent reviewers for suitability. A qualitative synthesis of the results was performed. RESULTS Sixty-six studies were identified. The majority of studies were Level III-3 as assessed by the NHMRC Evidence Hierarchy, whilst just over half of the studies were of good quality. Definitive surgery performed at specialised sarcoma centres was associated with improved local control as defined by lower rate of local relapse, higher rate of negative surgical margins, improved local recurrence free survival and higher limb conservation rate. Available evidences show a favourable pattern of lower 30-day and 90-day mortality rates, and greater overall survival when surgery was performed in specialist sarcoma centres compared with non-specialised centres. CONCLUSIONS Evidences support better oncological outcomes when surgery is performed at specialised sarcoma centre. Patients with suspected sarcoma should be referred early to a specialised sarcoma centre for multidisciplinary management, which includes planned biopsy and definitive surgery.

Abstract
Management of acute limb ischemia is complex and time sensitive, and delays in diagnosis and treatment may lead to irreversible tissue damage. Current data challenge the commonly accepted 6-hour ischemic threshold for acute limb ischemia, although variations in practice remain. Patients with chronic peripheral artery disease may tolerate longer ischemia time due to presence of collateral circulation. Here the authors discuss the presentation, workup, management, and postoperative care of patients with acute limb ischemia, with a focus on how management is altered depending on the duration and degree of ischemia.

Abstract
BACKGROUND The aim of the study was to assess the functional and oncological outcomes of patients with distal femoral osteosarcoma managed by limb salvage using modular endoprosthesis as well as to assess related complications. PATIENTS AND METHODS A total of 82 patients were included in our study. Functional outcome was assessed using MSTS score and knee range of motion. Oncological outcome was assessed regarding local recurrence, chest metastasis, and patient survivorship. Complications were classified according to Henderson et al. RESULTS: The mean MSTS score was 26.21 (87.4%) (range 8-30 points) with 70.7% of patients having more than 90° of flexion. The incidence of local recurrence was 3.7% (3 patients), while the incidence of chest metastasis was 14.6% (12 patients). Aseptic loosening (type 2 failure) was the commonest complication (19.5%), followed by infection (15.9%). The 5- and 10-year survivorships of the limb were 98.8%, while the 5- and 10-year survivorships of the prosthesis were 67.7% and 52.4%, respectively. CONCLUSION This study showed that patients with osteosarcoma distal femur who are treated by chemotherapy and limb salvage have an excellent long-term prognosis in terms of patient as well as limb survivorship. The use of modular endoprosthesis in these patients offer an acceptable function, with two-thirds of the patients retaining their prosthesis after 5 years and more than half retaining them after 10 years.

Abstract
PURPOSE To evaluate long-term clinical outcomes after revascularization by bypass graft versus Fogarty balloon catheter in acute blunt popliteal artery injury and identify risk factors contributing to amputation. METHODS A retrospective review was conducted in patients treated for acute blunt PAI between 2011 and 2019. Inclusion criteria were patients who underwent bypass graft and Fogarty balloon catheter. The cumulative limb salvage rate was calculated by the Kaplan-Meier test and compared with Breslow-Wilcoxon test. Cox proportional hazard model was performed to estimate the potential risk factors for amputation. Receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value for the potential risk factors. RESULTS The overall limb salvage rate was 60.4% (29/48), including 24 patients (66.7%) in bypass graft, and 5 patients (41.7%) in Fogarty balloon catheter with mean follow-up of 5 years (range, 2-10 years). Among amputees, 15 patients (15/19, 78.9%) received primary amputation due to vascular failure or severe soft tissue damage, and 4 received secondary amputation because of chronic bone infection or neurologic deficit. Kaplan-Meier curves showed patients who received Fogarty balloon catheter had significantly higher amputation rate than those received bypass graft, with a hazard ratio of 3.801 (95% CI: 1.162-12.43, p = 0.009). In addition, Cox proportional hazard model revealed that MESS was the only independent risk factor for patients developing amputation, and the optimal cut-off value of MESS was 8. CONCLUSION Five-year outcome demonstrated that Fogarty balloon catheter is not a safe procedure and has significantly higher amputation rate in severe blunt PAI. MESS is the only risk factor for amputation.

Abstract
BACKGROUND Common mental disorders (CMD) are highly morbid conditions not routinely screened for in chronic wound care. A comorbid psychiatric condition's influence on a patient with chronic wounds' quality of life (QoL) is unknown. This study investigates the implications of CMD on QoL in patients with chronic lower extremity (LE) wounds. METHODS This cross-sectional study surveyed patients with chronic LE wounds evaluated in our multidisciplinary clinic between June-July 2022. Surveys included validated physical and social QoL questionnaires, including the Lower Extremity Functional Scale (LEFS), Patient-Reported Outcomes Measurement Information System (PROMIS-3a) Scale v2.0, 12-Item Short-Form (SF-12), and a screening tool for common mental disorders, the Self-Reporting Questionnaire 20 (SRQ-20). Data regarding patient demographics, comorbidities, psychiatric diagnoses, and wound care history were retrospectively collected. RESULTS Of the 265 identified patients, 39 (14.7%) had documented psychiatric diagnoses, most often depression or anxiety. The diagnosed cohort had higher median SRQ-20 scores (6, IQR: 6 vs. 3, IQR: 5; P < 0.001) and a higher proportion of positive screens for CMD (30.8% vs. 15.5%; P = 0.020) than non-diagnosed patients. There were no differences in physical or social QoL in patients with and without a psychiatric diagnosis. However, individuals screening positively for CMD experienced significantly more pain (T-score 60.2 vs. 51.4, P = 0.0052) and reduced function (LEFS 26.0 vs. 41.0, P < 0.0000). CONCLUSION This study illustrates that patients with chronic LE wounds experience potentially meaningful psychologic distress. Further, symptoms of a CMD (SRQ-20 ≥8), rather than a previous diagnosis, may influence pain and functional outcomes. These findings emphasize the potential relevance of psychological distress in this population and reinforce the need for further investigation of actionable responses to this apparent need.

Abstract
Introduction Blunt trauma of the lower limb with vascular injury can cause devastating outcomes, including loss of limb and even loss of life. The primary aim of this study was to determine the limb salvage rate of patients sustaining such injuries when treated at Leeds General Infirmary (LGI) since becoming a Major Trauma Centre (MTC). The secondary aim was to establish patient complications. Methods A retrospective analysis found that from 2013 to 2018, 30 patients, comprising of 32 injured limbs, were treated for blunt trauma to the lower limb associated with vascular injury. Results Twenty-four patients were male and six were female. Their mean ages were 32 and 49, respectively. Three limbs were deemed unsalvageable and underwent primary amputation; of the remaining 29 potentially salvageable limbs, 27 (93%) were saved. Median ischaemic times for both amputees and salvaged limbs were under 6 hours. Of the 32 limbs, 27 (84%) were salvaged. All amputees had a MESS score ≥ 7, although not all patients with MESS ≥ 7 required amputation. Eleven limbs had prophylactic fasciotomies, three limbs developed compartment syndrome - all successfully treated and three contracted deep infections - one of which necessitated amputation. All but one patient survived their injuries and were discharged from the hospital. Conclusion Attempted salvage of 27/29 (93%) limbs was successful and all but one patient survived these injuries when treated at an MTC. MESS scoring and ischaemic time are useful but not sole predictors of limb salvage. Complication rates are low but may be significant for their future implications.

Abstract
OBJECTIVES Vascular Emergency Clinics (VEC) improve patient outcomes in chronic limb-threatening ischaemia (CLTI). They provide a "one stop" open access policy, whereby "suspicion of CLTI" by a healthcare professional or patient leads to a direct review. We assessed the resilience of the outpatient VEC model to the first year of the coronavirus disease (COVID-19) pandemic. METHODS A retrospective review of a prospectively maintained database of all patients assessed in our VEC for lower limb pathologies between March 2020 and April 2021 was performed. This was cross referenced to national and loco-regional Governmental COVID-19 data. Individuals with CLTI were further analysed to determine PAD-QIF (Peripheral Arterial Disease - Quality Improvement Framework) compliance. RESULTS Seven hundred and ninety-one patients attended for 1084 assessments (Male n = 484, 61%; Age 72.5 ± SD 12.2 years; White British n = 645, 81.7%). In total, 322 patients were diagnosed with CLTI (40.7%). A total of 188 individuals (58.6%) underwent a first revascularisation strategy (Endovascular n=128, 39.8%; Hybrid n=41, 12.7%; Open surgery n=19; 5.9%; Conservative n=134; 41.6%). Major lower limb amputation rate was 10.9% (n=35) and mortality rate was 25.8% (n=83) at 12 months follow up. Median referral to assessment time was 3 days (IQR 1-5). For the non-admitted patient with CLTI, the median assessment to intervention was eight days (IQR 6-15) and median referral to intervention time of 11 days (11-18). CONCLUSIONS The VEC model has demonstrated strong resilience to the COVID-19 pandemic with rapid treatment timelines maintained for patients with CLTI.

Abstract
BACKGROUND Shoulder soft tissue function reconstruction during tumor-type hemishoulder replacement is an important step to restore shoulder function. This study evaluates the functional prognosis and postoperative complications of ligament advanced reinforcement system (LARS)-assisted soft tissue functional reconstruction in tumor-type hemi-shoulder replacement. MATERIALS AND METHODS Twenty-two patients with an average age of 37.5 ± 17.8 years diagnosed with benign invasive tumors, primary malignant bone tumors, or bone metastases were enrolled in this study. The patient's medical records (history and surgical details), histological sections, imaging files, oncological prognosis, functional prognosis, and postoperative complications were collected. The upper limb function and shoulder joint function were evaluated using the Musculoskeletal Tumor Society (MSTS) system and American Shoulder and Elbow Surgeons (ASES) scoring criteria, respectively. RESULTS Twenty-two patients comprising 12 males and 10 females were enrolled. Overall, 9 patients had preoperative pathological fractures. The mean lesion length was 8.6 ± 3.0 cm. The local recurrence was observed in 3 cases, including 2 cases of osteosarcoma and 1 case of MGCT. A further 4 cases had pulmonary metastasis, including 2 cases with local tumor recurrence. The average postoperative MSTS score was 25.8 ± 1.7, and the score of postoperative ASES was 85.7 ± 6.0, both of which showed satisfactory functional recovery. Two cases experienced postoperative complications requiring surgical intervention, including one periprosthetic fracture and one giant cell granuloma. Prosthesis dislocation occurred in 1 case. None of the cases of periprosthetic infection or postoperative complications resulted in implant failure. CONCLUSIONS LARS-assisted soft tissue function reconstruction in benign and malignant proximal humerus tumors after a tumor-type hemi-shoulder replacement is an effective technical improvement, which can effectively repair the integrity of the joint capsule to restore joint stability, provide a medium for soft tissue attachment to rebuild the muscular dynamic system, and eliminate residual dead space around the prosthesis, effectively improving limb function and reduce postoperative infection complications.

Abstract
OBJECTIVE The SVS Wound, Ischemia, foot Infection (WIfI) limb staging system was established to estimate risk of major amputation in chronic limb-threatening ischemia (CLTI) and better stratify outcomes comparisons. There is little data on treatment outcomes beyond 1 year based on presenting WIfI stage. METHODS This is a single-institution retrospective study of 413 patients who underwent infrainguinal revascularization for CLTI (2011-2021) with data available for WIfI staging. Patient characteristics and outcomes were gathered from the electronic medical record. Data were analyzed based on presenting WIfI stage and initial treatment received at our center. RESULTS Presenting WIfI stages were 1 to 2 (23%), 3 (27%), and 4 (50%). Index revascularization approach was endoluminal (59%), autogenous vein bypass (29%), or non-autogenous bypass (13%). Operative mortality within 30 days was 2.9% and was not associated with WIfI stage or revascularization approach. Median limb follow-up time was 502 days (interquartile range [IQR], 112-1256 days), and median survival follow-up time was 932 days (IQR, 343-1770 days). Major amputation or death occurred in 19% and 46% of patients at median times of 119 days (IQR, 28-314 days) and 739 days (IQR, 204-1475 days), respectively. WIfI stage was independently associated with major amputation (P = .001), as was initial revascularization approach (P = .01). In a Cox proportional hazards model, factors independently associated with major amputation were male sex (hazard ratio [HR], 1.4; 95% confidence interval [CI], 1.04-2.0; P = .03), diabetes (HR, 1.8; 95% CI, 1.3-2.5; P = .001), WIfI stage 4 (HR, 2.3; 95% CI, 1.5-3.5; P < .001), and non-autogenous bypass (HR, 2.9; 95% CI, 2.1-4.2; P < .001). In a Cox proportional hazards model for mortality, independently associated factors were age (HR, 1.04; 95% CI, 1.02-1.05; P < .001), end-stage renal disease (HR, 2.8; 95% CI, 1.9-4.0; P < .001), congestive heart failure (HR, 1.9; 95% CI, 1.4-2.5; P < .001), chronic obstructive pulmonary disease (HR, 1.5; 95% CI, 1.1-2.1; P = .02), and WIfI stage 4 (HR, 1.6; 95% CI, 1.04-2.2; P = .03). Among those presenting with WIfI stage 4 limbs, Kaplan-Meier estimated rates of freedom from major amputation or death at 2 years were 71% ± 3.7% and 68% ± 3.5%, respectively. In an inverse propensity weighted Cox proportional hazards model, non-white race (HR, 1.5; 95% CI, 1.01-2.2; P = .047), diabetes (HR, 2.0; 95% CI, 1.2-3.3; P = .008), Global Anatomic Staging System infrapopliteal grade (HR, 1.2; 95% CI, 1.05-1.3; P = .005), non-autogenous bypass (HR, 3.2; 95% CI, 1.9-5.3; P < .001), and endoluminal revascularization (HR, 2.6; 95% CI, 1.6-4.3; P < .001) were independently associated with major amputation in the WIfI stage 4 subgroup. CONCLUSIONS Presenting WIfI stage is strongly associated with long-term risks of major amputation and death following infrainguinal revascularization for CLTI and should be used to stratify outcomes comparisons. Effective revascularization is critical in WIfI stage 4 disease, and autogenous vein bypass provides durable long-term limb preservation.
