Abstract
Fibrosarcoma is a rare, highly malignant tumor that develops from uncontrolled overgrowth of fibroblastic cells. It may start as a painless lump or swelling under the skin. But as it grows, it can push surrounding structures - organs, muscles, nerves, or blood vessels - and lead to pain and tenderness. The treatment of fibrosarcoma depends on several factors such as size, grade, location of primary tumor, extent of spread, age, and general health condition of the patient. The main treatment is surgical removal of the primary tumor with wide-margin excision and amputation if localized in the limb. Prior to surgical intervention, radiotherapy can be applied to reduce the tumor size or following surgery to lower the risk of recurrence. Chemotherapy is indicated in cases of metastasis. Unfortunately, the prognosis of fibrosarcoma is not favorable. For high-grade fibrosarcoma, the five-year survival rate is around 30% and for low-grade fibrosarcoma, it is 50-80%, with recurrence in the first two to five years post-surgery. We encountered a case of high-grade fibrosarcoma with aggressive growth in a 36-year-old male, requiring above-knee amputation.

Abstract
Strategies have been researched and implemented to reduce the number of people with diabetic foot ulcers (DFUs). One problem is the accurate assessment of DFU severity, which is the main factor in resource allocation and treatment choice. The primary objective of this study was to assess pentraxin-3 as a biomarker of an infected DFU (IDFU), the limb amputation level prognosis, and patient survival. The secondary objectives were to evaluate and compare other markers, including white blood cells (WBCs), C-reactive protein (CRP), the erythrocyte sedimentation rate (ESR), and procalcitonin (PCT), for identifying IDFUs. Over a period of two years, 145 patients were followed; 131 of these were analyzed for this study. Pentraxin-3 was found to be a good predictor of death (p = 0.047). A comparison between IDFUs and DFUs revealed the following differences: PCT had the highest AUROC of 0.91, sensitivity of 93.7, and specificity of 83.3%. CRP had a cutoff value of 226 mg/L, an AUROC of 0.89, a sensitivity of 95.5%, and a specificity of 83.3%. Fibrinogen had an AUROC of 0.87 at a cutoff value of 5.29 g/L, with a good sensitivity and specificity of 85% and 87%, respectively. ESR had a cutoff value of 46 mm/h, an AUROC of 85%, a sensitivity of 83.7%, and a specificity of 83.3%. Pentraxin-3 showed promising results in predicting IDFUs and DFUs, and it served as a marker for the risk of death in IDFU patients during the 6 month follow-up. Other markers, including CRP, PCT, ESR, and fibrinogen, were more effective in differentiating between IDFUs and DFUs.

Abstract
Each year in Canada, a substantial number of adults undergo limb amputation, with lower limb amputation (LLA) the most prevalent. Enhancing walking ability is crucial for optimizing rehabilitation outcomes, promoting participation, and facilitating community reintegration. Overcoming challenges during the acute post-amputation phase and sub-acute rehabilitation necessitates alternative approaches, such as motor imagery and mental practice, to maximize rehabilitation success. However, the current evidence on activation patterns using motor imagery in individuals with LLA is limited. The primary objective was to assess the feasibility of observing brain activation during imagined walking in individuals with LLA utilizing 3T functional magnetic resonance imaging (fMRI). Eight individuals with LLA and 11 control subjects participated. Consistent with representations of the lower limbs, both control and amputee groups demonstrated bilateral activation in the medial surface of the primary motor and somatosensory cortices. However, individuals with lower limb amputations exhibited significantly greater activation during imagined walking, particularly in frontal regions and the medial surface of the primary motor and supplementary motor cortices. Furthermore, the volume of activation in the bilateral primary motor cortices was higher for participants with amputations compared to controls. The protocol developed in this study establishes a foundation for evaluating the effects of a gait training program that incorporates mental imagery alongside conventional rehabilitation practices, in contrast to standard care alone. This pilot investigation holds potential to enhance our understanding of brain plasticity in individuals with LLA and pave the way for more effective rehabilitation strategies to optimize functional recovery and community reintegration.

Abstract
Lower limbs' arterial calcification is significantly associated with the clinical severity of lower extremity artery disease (LEAD) in patients undergoing hemodialysis (HD). However, the association between arterial calcification of the lower limbs and long-term clinical outcomes in patients on HD has not been elucidated. Calcification scores of the superficial femoral artery (SFACS) and below-knee arteries (BKACS) were quantitatively evaluated in 97 HD patients who were followed for 10 years. Clinical outcomes, including all-cause and cardiovascular mortality, cardiovascular events, and limb amputation were evaluated. Risk factors for clinical outcomes were evaluated using univariate and multivariate Cox proportional hazard analyses. Furthermore, SFACS and BKACS were divided into three groups (low, middle, and high), and their associations with clinical outcomes were evaluated using Kaplan-Meier analysis. SFACS, BKACS, C-reactive protein, serum albumin, age, diabetes, presence of ischemic heart disease, and critical limb-threatening ischemia were significantly associated with 3-year and 10-year clinical outcomes in the univariate analysis. Multivariate analysis showed that SFACS was an independent factor associated with 10-year cardiovascular events and limb amputations. Kaplan-Meier life table analysis showed that higher SFACS and BKACS levels were significantly associated with cardiovascular events and mortality. In conclusion, long-term clinical outcomes and the risk factors in patients undergoing HD were evaluated. Arterial calcification of the lower limbs was strongly associated with 10-year cardiovascular events and mortality in patients undergoing HD.

Abstract
Even if the vascular repair is successful, the frequency of limb loss is still high when popliteal artery injury is associated with postischemic syndrome due to blunt trauma or a prolonged ischemic time. Because prolonged ischemia interferes with an injured foot rescue, shortening of the ischemic time is a major aim of surgeons. We present two types of transient external arterial bypass and two cases of ischemic extremities due to main arterial injury. Even though the injured extremities had no circulation for more than 6 h, a transient external arterial bypass supplied circulation immediately, and they were reconstructed successfully. Although transient external arterial bypass is a dated technique, it is a recommended option, especially in the management of acute traumatic ischemia of the extremities to shorten the ischemic time and provide immediate reperfusion, which will bring the opportunity to save the ischemic limbs.

Abstract
OBJECTIVES This study is aimed at assessing the safety and effectiveness of an advanced flowable wound matrix (FWM) in the treatment of hard-to-heal vascular leg ulcers that often involve deep structures, are irregular and/or tunnelled or excavated. METHODS Records of patients seen at our Vascular Surgery Unit, at the University of Campania 'Luigi Vanvitelli', for hard-to-heal vascular leg ulcers between January 2018 and January 2020 were retrospectively reviewed. For each wound aetiology, area and complications were recorded and evaluated. Every patient received one or more applications of FWM and was followed up. RESULTS A total of 22 patients (18 female/four male), mean age 63±8.5 years, were treated. The initial wound area ranged from 4-58cm2. After wound bed preparation, FWM was applied. Treatment was well tolerated and effective-rate of complications was low, graft take was very satisfactory, and no graft loss, rejection or superimposed infections were observed. Healing time was short: 85% of ulcers healed after 12 weeks. Most importantly, there was a decrease in the rate and level of amputations as compared with standard wound care. CONCLUSIONS The data presented indicate that FWM is an option for the treatment of hard-to-heal vascular leg ulcers, particularly for those with an irregular cavity. DECLARATION OF INTEREST The authors have no conflicts of interest.

Abstract
Introduction Diabetic foot infection is a condition that affects the patient's life, may cause limb loss, and has a high mortality. Too many parameters were used for predicting early mortality but the gold standard method wasn't described. Neutrophil lymphocyte ratio (NLR) is universally accepted as a predictive value for amputation-free survival and mortality. NLR increases due to inflammation-induced neutrophilia and lymphopenia related to cortisol-induced stress. Increasing in the neutrophil albumin ratio is expected due to decreasing albumin levels because albumin is a negative acute-phase reactant. The aim of this study is to investigate the sensitivity and value of the neutrophil albumin ratio (NAR) for early mortality after major lower extremity amputation (LEA). Methods Following the approval of the ethics committee, 87 patients who underwent major LEA between May 2018 and May 2020 were analyzed for the study. White blood cell (WBC), neutrophil, lymphocyte, C-reactive protein (CRP), creatinine, albumin, platelet, and hemoglobin values on the day prior to surgery were recorded. NLR was calculated as the ratio of neutrophil count to lymphocyte count, NAR as the ratio of neutrophil count to albumin value, CRP/albumin ratio (CAR) as the ratio of CRP value to albumin value, and platelet lymphocyte ratio (PLR) as the ratio of platelet count to lymphocyte count. Each parameter was also recorded in the postoperative second week. Results Of the patients included in the study, 52 were men (59.8%) and 35 were women (40.2%). It was determined that 29 of 87 patients (33.3%) died within the first year. The relationship between post-operative NAR value and early mortality is examined. The area under the curve was calculated as 0.873. When the cut-off value was applied as 0.265, the sensitivity was found as 88% and specificity as 76%. Conclusions Higher neutrophil/albumin ratio after lower extremity amputation was associated with early mortality after extremity amputation. This parameter can help predict mortality. The cut-off value was determined as 0.265, the sensitivity was found as 88%, and specificity as 76%.

Abstract
We present five members of a consanguineous Pakistani kinship with the most severe familial tetramelic transverse autopod deficiency reported to date and additionally having some of the common autosomal recessive Robinow syndrome-1 (RRS1) features including short stature, short neck, severe vertebral anomalies of kyphoscoliosis, hemivertebrae, fusion of thoracic vertebrae, broad forehead, and dental crowding. We mapped the locus of this atypical RRS and detected homozygous 8-nucleotide deletion c.1353_1360del (p.(Met452Alafs*4)) in ROR2, the gene responsible for RRS1. We did not find any other variant shared by all affected individuals that could possibly act as a modifier of limb defect. Autopods are affected in RRS1, but severe autopod deficiency is not a characteristic feature. Over 30 biallelic variants dispersed throughout the gene are known in ROR2-related RS, with no genotype-phenotype correlation for specific RRS1 features. Considering together with the sporadic case homozygous for variant p.(Arg442*) and the case homozygous for p.(Arg441Thrfs*16) in a family where heterozygous members have brachydactyly type B1, we propose that homozygous truncating variants that originate at residues 441-452 can cause severe autopod reduction anomalies, suggesting some genotype-phenotype correlation for this particular phenotype.

Abstract
The study aimed to identify the psychological changes that result from the amputation of a limb and the ways in which patients coordinate their daily lives. The study uses an interpretative phenomenological analysis (IPA) aimed at understanding individual experiences in seven patients who have suffered limb amputation. The method used consisted of individual, semi-structured interviews, conducted approximately 4 months after surgery, to patients at home or in hospital, at the time of their regular checkup. The interviews were audio recorded, transcribed and, following the qualitative analysis performed, six common themes were identified: emotional impact, negative affects, tendency toward isolation, role constraints and limitations, phantom limb, and emotional balancing. A specific theme for patients who have suffered amputations is phantom limb pain, which has received special attention from researchers. The last topic relates to the tendency toward emotional balancing and psychological calibration to return to normal life.

Abstract
Traumatic heterotopic ossification (tHO) commonly develops in wounded service members who sustain high-energy and blast-related traumatic amputations. Currently, no safe and effective preventive measures have been identified for this patient population. Bone morphogenetic protein (BMP) signaling blockade has previously been shown to reduce ectopic bone formation in genetic models of HO. In this study, we demonstrate the efficacy of small-molecule inhibition with LDN193189 (ALK2/ALK3 inhibition), LDN212854 (ALK2-biased inhibition), and BMP ligand trap ALK3-Fc at inhibiting early and late osteogenic differentiation of tissue-resident mesenchymal progenitor cells (MPCs) harvested from mice subjected to burn/tenotomy, a well-characterized trauma-induced model of HO. Using an established rat tHO model of blast-related extremity trauma and methicillin-resistant Staphylococcus aureus infection, a significant decrease in ectopic bone volume was observed by micro-computed tomography imaging following treatment with LDN193189, LDN212854, and ALK3-Fc. The efficacy of LDN193189 and LDN212854 in this model was associated with weight loss (17%-19%) within the first two postoperative weeks, and in the case of LDN193189, delayed wound healing and metastatic infection was observed, while ALK3-Fc was well tolerated. At day 14 following injury, RNA-Seq and quantitative reverse transcriptase-polymerase chain reaction analysis revealed that ALK3-Fc enhanced the expression of skeletal muscle structural genes and myogenic transcriptional factors while inhibiting the expression of inflammatory genes. Tissue-resident MPCs harvested from rats treated with ALK3-Fc exhibited reduced osteogenic differentiation, proliferation, and self-renewal capacity and diminished expression of genes associated with endochondral ossification and SMAD-dependent signaling pathways. Together, these results confirm the contribution of BMP signaling in osteogenic differentiation and ectopic bone formation and that a selective ligand-trap approach such as ALK3-Fc may be an effective and tolerable prophylactic strategy for tHO.

Abstract
The aim of this study was to explore the different meanings of the experience of lower-limb amputation due to vascular causes in the time period from the fifth to twelfth week post-amputation. A phenomenological study involving semi-structured interviews was carried out. Data collection took place in a Public Hospital in Spain and included a convenience sample of 20 patients who had undergone amputation. The study highlighted patients' fears related to mobility, pain, dependence, and autonomy. Moreover, patients experience of the rehabilitation process and resources for adaptation were described as well as all the changes related to the social environment. The figure of a nurse was considered essential after amputation by the patients. This study provides a deep understanding of their experiences at the immediate time after amputation considering patients demographical associations and the etiology of the vascular pathology. This could be the starting point to understand patients' immediate needs upon discharge.

Abstract
Critical limb ischemia (CLI) is the most advanced stage of peripheral arterial disease. It is clinically defined as rest pain with or without skin ulcer or gangrene and carries a very poor prognosis with a high rates of limb amputation and cardiovascular mortality. Despite the first definition of CLI has been published more than 30 years ago, the debate about what it really is, is still open. Over the years the hemodynamic parameters utilised to define the critical level of limb perfusion have changed. This has raised some question about the apparent confusion about the definition of CLI. Moreover, a new term such as "limb threatening ischemia" has replaced the definition of CLI in recent guideline. Therefore, it becomes necessary to understand the evolution of the concept and the definition of CLI, to interpret the future trend.Hence, this work analysing the guideline documents on peripheral arterial disease that have defined the CLI to date, aims to clarify the path that has brought to the current conceptual changes of the definition of CLI.

Abstract
Amputations have a devastating impact on patients' health with consequent psychological distress, economic loss, difficult reintegration into society, and often low embodiment of standard prosthetic replacement.The main characteristic of bionic limbs is that they establish an interface between the biological residuum and an electronic device, providing not only motor control of prosthesis but also sensitive feedback.Bionic limbs can be classified into three main groups, according to the type of the tissue interfaced: nerve-transferred muscle interfacing (targeted muscular reinnervation), direct muscle interfacing and direct nerve interfacing.Targeted muscular reinnervation (TMR) involves the transfer of the remaining nerves of the amputated stump to the available muscles.With direct muscle interfacing, direct intramuscular implants record muscular contractions which are then wirelessly captured through a coil integrated in the socket to actuate prosthesis movement.The third group is the direct interfacing of the residual nerves using implantable electrodes that enable reception of electric signals from the prosthetic sensors. This can improve sensation in the phantom limb.The surgical procedure for electrode implantation consists of targeting the proximal nerve area, competently introducing, placing, and fixing the electrodes and cables, while retaining movement of the arm/leg and nerve, and avoiding excessive neural damage.Advantages of bionic limbs are: the improvement of sensation, improved reintegration/embodiment of the artificial limb, and better controllability.

Abstract
Background In 2015, there were 30.3 million patients with diabetes in the US, including 25.2% of people ages 65 or older and 108,000 hospitalizations for non-traumatic amputations. Severe diabetic limb disease includes critical limb ischemia (CLI ) due to an infrapopliteal disease with foot pain and ischemic ulcerations including gangrene. Environmentally acquired toxic metals, such as lead and cadmium, have been associated with cardiovascular disease. Thus, we designed the present unblinded pilot study to determine whether there was a signal of benefit for edetate disodium-based infusions in patients with critical limb ischemia. Methods This was an open-label pilot study in 10 patients with diabetes and critical limb ischemia. Each patient received up to 50 edetate disodium-based infusions and was assessed for safety, clinical efficacy, metal excretion, and quality of life. The primary endpoint was to assess the effect of edetate disodium-based therapy plus vitamins in patients with diabetes and infra-popliteal peripheral artery disease presenting with severe CLI and determine if there were improvements in vascular flow parameters. Results We enrolled 10 (60% male) predominantly Caucasian (90%) subjects. The mean age was 75.3 (8.0) years. Smoking was reported by 30%. There were 70% with coronary artery disease (30% had prior coronary artery bypass grafting) and 50% had a prior lower-extremity amputation, three having previous minor amputations and two major amputations. There were no major adverse cardiovascular events during the infusion phase through the one-year follow-up. Patients completing 40 infusions demonstrated complete wound healing and improvement in the quality of life. Conclusion Patients with diabetes and CLI treated with a regimen of edetate disodium-based infusions demonstrated a potential signal of benefit and preliminary evidence of safety. The Trial to Assess Chelation Therapy in Critical Limb Ischemia (TACT3a), a randomized double-blind, placebo-controlled clinical trial now in progress, will further test these findings.

Abstract
Background: Amputation is one of the oldest known surgical procedures. It has been one of the modalities of applying judgment and treatment. Its method and indications has evolved over time. Modern amputation is regarded as a part of treatment rather than failure of treatment. Amputation is the removal of a limb or part of a limb through on or more bone. When through a joint is referred to as disarticulation. Data on the profile and pattern of amputation in Liberia will add to the body of knowledge. Aim and Objectives: Is to describe the pattern of limb of amputations in Liberia. Also to describe the anatomical variations of limb amputations in Liberia. Patients and Method: A retrospective study of all patients that underwent limb amputation surgeries in the John F Kennedy Memorial (JFK M), Hospital, Monrovia Liberia between January 2010 to December 2015. Results: 100 patients had limb amputations between 2010 and 2015. Males(73) to female(27) ratio were 2.4:1. The age range was 9 - 91 years. Mean age was 42.9 years. The indications for amputations were Trauma 24%, Diabetes 29%, Gangrene (6%), Chronic ulcer (25%), Tumour (5%). Below knee(47%), Above Knee(45%), Below elbow(2%), Above Elbow(2%), Knee Disarticulation(2%), and Big Toe Disarticulation(2%). Conclusion: The profile of Limb amputation in Liberia is not very different from what is obtaining in the region. However the limitations of histology and other investigative procedure have affected the accurate diagnosis of certain conditions like tumours.

Abstract
Objective: To describe the characteristics, the management and the outcome of a consecutive series of patients with diabetic foot lesions (DF) and no-option critical limb ischemia (CLI) treated with a multidimensional, interdisciplinary approach in a dedicated center. Research Design and Methods: The prospective database of the Diabetic Foot Unit of the Maria Cecilia Hospital (Cotignola, Italy) collects medical history, risk factors, chemistry values, angiographic data, characteristic of foot lesions, medical and surgical therapies of all patients admitted with a diagnosis of DF and CLI. All patients were followed-up for at least 1 year and/or total recovery. The primary endpoint was 1-year amputation-free survival (AFS), secondary endpoints were limb salvage and survival. Results: Between October 2014 and October 2017, 1024 patients with DF and CLI were admitted to the center. Eighty-four of them (8.2%) fulfilled the criteria for no-option CLI. At 1 year, AFS, limb salvage, and survival rates were 34%, 34%, and 83%, respectively. Lesions located proximal to the Lisfranc joint were associated with major amputation (HR 2.1 [1.2–3.6]). One-year survival of patients treated with minor procedures was significantly higher compared to patients treated with major amputation (96% vs 76%, log-rank p = 0.019). Major amputation was independently associated with mortality (HR 7.83 [1.02–59.89]). Conclusions: The application of dedicated and standardized strategies permitted limb salvage in one-third of patients with no-option CLI. Patients with stable lesions limited to the forefoot and without ischaemic pain had a greater probability to successfully receive conservative treatments. Limb salvage was associated with subsequent higher one-year survival.

Abstract
Introduction Previous studies have shown that veterans with lower limb amputation have a higher risk for cardiovascular disease (CVD) compared with population-based controls. American veterans who have served in Iraq and Afghanistan with lower limb amputation may be at a similarly higher risk. Patients and methods The Navel Health Research Center (NHRC) maintains the Expeditionary Medical Encounter Database (EMED) of military personnel who have sustained combat limb amputation or serious limb injury during the conflicts in Iraq and Afghanistan. Department of Veterans Affairs data from 2003 to April 2015 was used to analyze CVD risk factors in this cohort. Veterans with either unilateral (n=442) or bilateral (n=146) lower limb amputation were compared to those with serious lower limb trauma without amputation (n=184). Multivariate regression was used to measure associations between lower limb amputation and CVD risk factors over an average of 8 years of follow-up. Outcomes included mean arterial pressure (MAP), low-density lipoprotein, high-density lipoprotein (HDL), and serum triglycerides (TG). Results Compared with the limb injury group, those with unilateral lower limb amputation had significantly lower HDL (p<0.05) and higher TG (p<0.05). Those with bilateral lower limb amputation had significantly higher MAP (p<0.05), lower HDL (p<0.01), and higher TG (p<0.001). The prevalence of metabolic syndrome, defined as type 2 diabetes or a constellation of blood pressure and lipid changes consistent with metabolic syndrome, was 8.7%, 14.9%, and 21.9% for limb injury, unilateral amputation, and bilateral amputation groups, respectively. Veterans with bilateral lower limb amputation had a 2.25-increased odds ratio (95% confidence interval 1.19–5.05) of type 2 diabetes or blood pressure and lipid changes consistent with metabolic syndrome compared to those with limb injury. Conclusions Results suggest that veterans with lower limb amputation have a higher risk for metabolic syndrome. Primary care interventions to manage weight, blood pressure, and lipid levels are fundamental in order to reduce cardiac risk in this relatively young cohort.

Abstract
BACKGROUND Diabetes confers an increased risk for atherosclerotic cardiovascular disease, but less is known about the independent risk diabetes confers on major cardiovascular and limb events in patients with symptomatic peripheral artery disease (PAD) on contemporary management. OBJECTIVES The authors sought to assess the risk of cardiovascular and limb events in patients with PAD and diabetes as compared with those with PAD alone. METHODS In the EUCLID (Examining Use of Ticagrelor in Peripheral Artery Disease) trial, 13,885 patients with symptomatic PAD were evaluated with a primary endpoint of an adjudicated composite of major adverse cardiovascular events (MACE) (cardiovascular death, myocardial infarction, ischemic stroke) followed over a median of ∼30 months. The diabetes subgroup was analyzed compared with the subgroup without diabetes, and further examined for diabetes-specific factors such as glycosylated hemoglobin (HbA1c) that might affect risk for major cardiovascular and limb outcomes. RESULTS A total of 5,345 patients (38.5%) had diabetes; the majority (n = 5,134 [96.1%]) had type 2 diabetes. The primary endpoint occurred in 15.9% of patients with PAD and diabetes as compared with 10.4% of those without diabetes (absolute risk difference 5.5%; adjusted hazard ratio: 1.56; 95% confidence interval [CI]: 1.41 to 1.72; p < 0.001). Every 1% increase in HbA1c was associated with a 14.2% increased relative risk for MACE (95% CI: 1.09 to 1.20; p < 0.0001). CONCLUSIONS Patients with PAD and diabetes are at high risk for cardiovascular and limb ischemic events, even on contemporary therapies. Every 1% increase in HbA1c was associated with a 14.2% increased relative risk for MACE (95% CI: 1.09 to 1.20; p < 0.0001).

Abstract
Several studies have analyzed human gait data obtained from inertial gyroscope and accelerometer sensors mounted on different parts of the body. In this article, we take a step further in gait analysis and provide a methodology for predicting the movements of the legs, which can be applied in prosthesis to imitate the missing part of the leg in walking. In particular, we propose a method, called GaIn, to control non-invasive, robotic, prosthetic legs. GaIn can infer the movements of both missing shanks and feet for humans suffering from double trans-femoral amputation using biologically inspired recurrent neural networks. Predictions are performed for casual walking related activities such as walking, taking stairs, and running based on thigh movement. In our experimental tests, GaIn achieved a 4.55 prediction error for shank movements on average. However, a patient's intention to stand up and sit down cannot be inferred from thigh movements. In fact, intention causes thigh movements while the shanks and feet remain roughly still. The GaIn system can be triggered by thigh muscle activities measured with electromyography (EMG) sensors to make robotic prosthetic legs perform standing up and sitting down actions. The GaIn system has low prediction latency and is fast and computationally inexpensive to be deployed on mobile platforms and portable devices.

Abstract
BACKGROUND: Few studies have analyzed the benefit of limb amputations in children with metastatic osteosarcoma and limited life span. OBJECTIVE: We studied outcomes of limb amputations in children with metastatic osteosarcoma. DESIGN: We performed a retrospective review of patients who underwent limb amputations (January 1995-June 2015) and died within 1 year of surgery. SETTING/PARTICIPANTS: We studied 12 patients with osteosarcoma at a single institution. MEASUREMENTS: Data on mobility, pain, and emotional and psychological well-being were retrieved from medical records from 1 month before surgery to 6 months after surgery. RESULTS: Of the 12 patients (7 females and 5 males; median age at surgery 13 years [range, 7-20 years]) meeting study criteria, 3 patients and 9 patients had primary osteosarcoma in upper and lower limbs, respectively. Mobility improved postamputation in 8 bedridden/wheelchair-bound patients. Postamputation, emotional, and psychological well-being improved for 9 patients, 3 patients had persistent psychological and/or emotional symptoms, and no patient experienced signs of regret. Daily mean pain scores were significantly lower at 1 week (median 3 [range, 0-6]; P = .03) and 3 months (median 0 [range, 0-8]; P = .02) postsurgery than at 1 week presurgery (median 5.5 [range, 0-10]). Morphine consumption (mg/kg/d) showed a trend toward higher values at 1 week (median 0.2 [range, 0-7.6]; P = .6) and 3 months (median 0.2 [range, 0-0.5]; P = .3) postsurgery than at 1 week presurgery (median 0.1 [range, 0-0.5]). CONCLUSIONS: Patients undergoing limb amputations had reduced pain and improved mobility and emotional and psychological well-being. Amputations are likely to benefit children with limited life expectancy.

Abstract
Introduction Diabetic foot infections are a major cause of non-traumatic amputations. The role of anaerobes in the prognosis of these infections is particularly unclear. This study was conducted with the aim of correlating microbiological profiles with clinical outcomes in these diabetic foot ulcer patients. Methodology This prospective observational study was done in a tertiary care centre in South India. All patients admitted with diabetic foot ulcers for two years were included in the study. Tissue biopsies were collected from the ulcer for aerobic and anaerobic cultures. The patients were grouped as those with aerobic infection alone (anaerobe negative) and those with mixed aerobic and anaerobic infections (anaerobe positive). Anaerobic culture was performed using the Robertson cooked meat (RCM) medium. The ulcer of the foot was described with respect to site, size, duration, history of previous amputation(s), and history of number and class of antibiotic intake prior to hospitalization. Clinical course and Wagner's grades of the diabetic foot ulcers were compared for aerobic and anaerobic infections. Results A total of 104 patients were included in the study. There were no significant differences between the two groups with regards to duration of diabetes, random blood sugar (RBS) at the time of admission, compliance to drugs, and mode of blood sugar control and prior intake of antibiotics. Patients with anaerobic infections were found to have a higher incidence of fever in this study (38.1% vs. 14.5%; p = 0.0057), as compared to patients with aerobic infections. More than half of the patients in the anaerobic infection group presented with Wagner's grade IV and above, as compared to the aerobic infection group (59.5% vs. 32.2%; p = 0.0059), which was statistically significant. Patients with anaerobic infections also had high numbers of major and minor amputations when compared to patients with aerobic infections. Conclusion Septic diabetic foot patients with fever at the time of admission and a high Wagner's grade have a greater chance of harbouring anaerobic infections. Drugs for anaerobic coverage should be considered for wounds beyond Wagner's grade III. Anaerobic infections resulted in increased risk of morbidity in diabetic foot ulcer patients but did not have any influence on mortality.

Abstract
Although involuntary movements of stumps are less frequent than phantom sensation or other neurological sequelae of limb amputation, they represent a phenomenon that has been known for many years. The pathophysiology remains unknown, but it seems to be related to damage to the peripheral nervous system. Treatment is not standardized, but antimyoclonic drugs seem to be useful.

Abstract
INTRODUCTION Xenomelia is a rare condition characterized by the persistent and compulsive desire for the amputation of one or more physically healthy limbs. We highlight the neurological underpinnings of xenomelia by assessing structural and functional connectivity by means of whole-brain connectome and network analyses of regions previously implicated in empirical research in this condition. METHODS We compared structural and functional connectivity between 13 xenomelic men with matched controls using diffusion tensor imaging combined with fiber tractography and resting state functional magnetic resonance imaging. Altered connectivity in xenomelia within the sensorimotor system has been predicted. RESULTS We found subnetworks showing structural and functional hyperconnectivity in xenomelia compared with controls. These subnetworks were lateralized to the right hemisphere and mainly comprised by nodes belonging to the sensorimotor system. In the connectome analyses, the paracentral lobule, supplementary motor area, postcentral gyrus, basal ganglia, and the cerebellum were hyperconnected to each other, whereas in the xenomelia-specific network analyses, hyperconnected nodes have been found in the superior parietal lobule, primary and secondary somatosensory cortex, premotor cortex, basal ganglia, thalamus, and insula. CONCLUSIONS Our study provides empirical evidence of structural and functional hyperconnectivity within the sensorimotor system including those regions that are core for the reconstruction of a coherent body image. Aberrant connectivity is a common response to focal neurological damage. As exemplified here, it may affect different brain regions differentially. Due to the small sample size, our findings must be interpreted cautiously and future studies are needed to elucidate potential associations between hyperconnectivity and limb disownership reported in xenomelia.

Abstract
INTRODUCTION : The Pakistan military has been actively engaged in the war against terror for more than a decade. Many officers and soldiers have lost their limbs in this war. But the data on traumatic lower limb amputations in Pakistan is sparse. The aim of this study is to prospectively document the epidemiological profile of lower limb military amputees presenting at the largest rehabilitation centre of Pakistan over a three-year period. MATERIALS & METHODS : A prospective three-year survey was conducted at the Armed Forces Institute of Rehabilitation Medicine (AFIRM), Pakistan. One hundred twenty-three consecutive patients with lower limb amputations were enrolled in the survey. The demographic data, etiology, associated injuries, complications profile, and type of prosthesis provided were documented. The data analysis was done using the statistical analysis tool SPSS V 20 (IBM®,NY, USA). RESULTS : All patients were male. Most had traumatic amputation (119), were between 20-40 years (106), with unilateral amputation (115). Mine blast injury was the leading cause in 73 (59.3%) and most (58.5%) were fitted with modular prosthesis. Transtibial amputation was the commonest level (65), followed by transfemoral (30). The time of surgical amputation was not documented in 87% of the patients. Half of the patients (54%) had associated injuries. Seventy-nine patients had at least one complication with phantom pain being the commonest in 25% cases. CONCLUSIONS : This is the largest prospective demographic survey of lower limb amputees in Pakistan military to date. Scores of soldiers and civilians in Pakistan have suffered lower limb amputation. The availability of demographic data can improve the trauma and rehabilitation services for better understanding and management of such cases. There is a need to conduct large scale community-based epidemiological surveys to direct future policies and develop amputee rehabilitation services in the public sector.

Abstract
Despite progress in research and media attention on active upper limb prostheses, presently the most common commercial upper limb prosthetic devices are not fundamentally different from solutions offered almost one century ago. Limited information transfer for both control and sensory-motor integration and challenges in socket technology have been major obstacles. By analysing the present state-of-the-art and academic achievements, we provide our opinion on the future of upper limb prostheses. We believe that surgical procedures for muscle reinnervation and osseointegration will become increasingly clinically relevant; muscle electrical signals will remain the main clinical means for prosthetic control; and chronic electrode implants, first in muscles (control), then in nerves (sensory feedback), will become viable clinical solutions. After decades of suspended clinically relevant progress, it is foreseeable that a new generation of upper limb prostheses will enter the market in the near future based on such advances, thereby offering substantial clinical benefit for patients.

Abstract
This review summarizes the available studies of a rare condition in which individuals seek the amputation of a healthy limb or desire to be paraplegic. Since 1977, case reports and group studies have been produced, trying to understand the cause of this unusual desire. The main etiological hypotheses are presented, from the psychological/psychiatric to the most recent neurologic explanation. The paradigms adopted and the clinical features are compared across studies and analyzed in detail. Finally, future directions and ethical implications are discussed. A proposal is made to adopt a multidisciplinary approach that comprises state-of-the-art technologies and a variety of theoretical models, including both body representation and psychological and sexual components.

Abstract
OBJECTIVES To determine the indications and complications of major limb amputations in a Nigerian hospital. DESIGN A five-year retrospective descriptive study. SETTING National Orthopaedic Hospital, Dala, Kano, Nigeria. PARTICIPANTS Patients who had amputations above the wrist or ankle between January 2006 and December 2010. MAIN OUTCOME MEASURES Indications, complications and mortality. RESULTS There were 132 unilateral amputations. The patients were mostly males and below the age of 40. Lower limb amputations (74.2%) exceeded upper limb amputations (25.8%). The commonest indication was trauma (42.4%) followed by TBS gangrene (31.8%) and malignant tumours (12.9%). Wound infection, the commonest complication, occurred in patients who had identifiable predisposing factors. The 3 deaths that occurred were in patients who had had traditional bone setter intervention: 2 were due to septicaemia; 1, due to severe tetanus. CONCLUSION Trauma and traditional bone setter gangrene were the commonest indications. Most of the amputations were avoidable. Institution of preventive measures is imperative. Paying attention to predisposing factors can reduce complications.

Abstract
Limb amputation is a life-changing event that signifies long-term physical, social, psychological, and environmental change. Spiritual well-being in patients plays a significant role in coping and may affect outcomes of patients with limb loss. The objective of this study was to describe the role of spirituality in individuals with limb amputation and to determine whether spirituality is related to the quality of life (QOL) in this sample. Study participants were recruited through prosthetists, physicians, amputee support groups, the Amputee Coalition of America, and amputee listserv discussion groups in the United States and Canada. Participants completed questionnaires containing measures of satisfaction with life, general health, mobility, and social integration. A quantitative descriptive research design was used to examine the relationships between existential spirituality (belief that one's life is meaningful or has purpose) and religious spirituality and QOL among individuals with limb amputation. A prospective study of 108 patients with a history of limb amputation was performed. The study population consisted of 66.3% males and 33.7% females. Most patients were Caucasian (96.2%). Of the 108 participants, 86 (79.6%) were 41 years of age or older with a mean of 18 years since amputation. The most frequent cause of amputation was trauma (55.6%) and the most common location of amputation was below-the-knee (49.1%). Existential spirituality, female gender, and age above 50 years related to higher QOL in patients with a history of limb amputation. The findings of this research confirmed that amputees use spirituality to cope with limb amputation. Existential spirituality was a significant predictor of satisfaction with life, general health, and social integration.

Abstract
Objective. To assess the score of SOC (sense of coherence), BDI (Beck Depression Scale), STAI ( State and Trait Anxiety Inventory) in three examined groups and correlation of SOC score with sociodemographic data, anxiety and depression. Methods. The SOC, BDI, STAI questionnaires were given to 51 patients after limb amputation, 65 patients after vertebral surgery because of chronic back pain and 40 persons in the control group. Results. Patients after limb amputation achieved the same level of SOC score as the control group. Patients who had higher results on the SOC score rarely suffered from phantom pain. Patients after spine surgery had a lower level on the SOC score than the control group. A lower score of SOC was observed in older, unemployed, poorer educated, subjects taking medicine, who did not report improvement after operation. Patients after limb amputation and patients after spinal surgery were more depressed and anxious than healthy people. Conclusion. Patients with higher SOC results, in both examined groups, were less depressed and anxious.
