transmetatarsal amputation

BACKGROUND: Late development of forefoot ulcers is a common finding after transmetatarsal amputation (TMA). The primary aim of this study was to examine whether concomitant prophylactic Achilles tendon lengthening (ATL) was associated with a reduction in the incidence of forefoot ulcers postoperatively. METHODS: A retrospective chart review was performed by 2 authors to identify patients who underwent TMA over a period of 5.5 years from January 1, 2015, through July 31, 2020...

BACKGROUND: Selecting the level of amputation for patients with severe foot pathology can be challenging. The surgeon is sometimes confronted with an option between transmetatarsal amputation (TMA) and below-knee amputation (BKA). Recent studies have suggested that minor foot amputations have high revision rates and need for higher level of amputation. This study sought to compare the revision rates, need for higher level of amputation, postoperative ambulatory rate, and the demographic factors between these 2 operations...

During the COVID-19 pandemic, high rates of arterial and venous thromboembolic (VTE) events were noted in association with increased rates of major amputation. VTE appears to be a significant source of morbidity and mortality for this patient population and numerous methods have been described to achieve limb salvage. Nevertheless, best management remains unclear. We describe the case of a 60-year-old male with severe venous gangrene secondary to a non-occlusive mid-femoral and occlusive infrapopliteal deep venous thromboses associated with COVID-19 infection who ultimately underwent meticulous local wound care and transmetatarsal amputation, which allowed for maximal preservation of foot function and limb salvage...

A persistent sciatic artery is a rare embryologic variant that usually presents with aneurysmal degeneration. This report describes a 66-year-old male with severe comorbidities who presented with right forefoot gangrene and COVID-19 infection. Imaging revealed a unilateral persistent sciatic artery with a chronic occlusion at the level of the knee joint with no aneurysm. After COVID-19 resolution, he underwent CO2 angiography with successful recanalization of the persistent sciatic artery followed by transmetatarsal amputation that healed uneventfully...

Background: Transmetatarsal amputation (TMA) is performed in patients with nonhealing wounds of the forefoot. Compared with below-knee amputations, healing after TMA is less reliable, and often leads to subsequent higher-level amputation. The aim of this study was to evaluate the functional and patient-reported outcomes of TMA. Methods: A retrospective review of patients who underwent TMA from 2013 to 2021 at our limb-salvage center was conducted. Primary outcomes included postoperative complications, secondary proximal lower extremity amputation, ambulatory status, and mortality...

Coronary artery bypass grafting (CABG) is the most common surgery performed by cardiothoracic surgeons worldwide. Risks of CABG include neurological outcomes, deep vein thrombosis, renal or gastrointestinal injury, and death. Perioperatively, some patients may need intra-aortic balloon pump (IABP) use to help assist with cardiac function. In this case, a 75-year-old man presented with multivessel myocardial infarction requiring IABP for cardiac assistance prior to undergoing CABG. Eighteen days after his CABG, his toes turned black at home...

INTRODUCTION: The purpose of this study was to identify associated risk factors for complications, need for a higher level of amputation such as below-knee amputation (BKA) or above-knee amputation (AKA), and mortality after transmetatarsal amputation (TMA). METHODS: We identified 265 patients who underwent 286 TMA procedures between June 2002 and July 2016. Medical records were reviewed for revision surgery and amputation. Mortality was verified using the National Death Index...

BACKGROUND: Diabetic lower-extremity disease is the primary driver of mortality in patients with diabetes. Amputations at the forefoot or ankle preserve limb length, increase function, and, ultimately, reduce deconditioning and mortality compared with higher-level amputations, such as below-the-knee amputations (BKAs). We sought to identify risk factors associated with amputation level to understand barriers to length-preserving amputations (LPAs). METHODS: Diabetic lower-extremity admissions were extracted from the 2012-2014 National Inpatient Survey using ICD-9-CM diagnosis codes...

We report a case of atherothrombotic microembolism in a 53-year-old male diagnosed with coronavirus disease 2019 (COVID-19) prior to hospital admission. Upon admission, Day 9 after diagnosis, he presented with COVID-19 pneumonia and mottling of the lower extremities. The patient was treated with anticoagulation therapy. The lower extremity angiogram showed a patent posterior tibial artery and a patent peroneal artery. Despite initial anticoagulation therapy, toe and transmetatarsal amputations were required...

Background: Diabetic foot infections are a common precursor to lower extremity amputations. The treatment of diabetic foot infections involves both medical and surgical management, of which limb-sparing surgeries are increasingly preferred over amputations at or above the ankle to preserve mobility and quality of life. The outcomes following these limb-sparing surgeries are not well described. Methods: This was a single-center, retrospective cohort study of 90 Veterans with moderate-to-severe diabetic foot infections between 2017 and 2019 from the Veterans Affairs Maryland Health Care System...

Importance: Cardiometabolic and other risk factors could render patients with gout more likely to undergo lower extremity amputation (LEA). Objective: To examine the rate of and factors associated with LEA in patients with gout. Design, Setting, and Participants: In this matched cohort study using national administrative data, multivariable Cox proportional hazards regression models were used to examine the associations of gout with LEA. In analyses limited to patients with gout, attributes of serum urate control and treatment with urate-lowering therapy were examined as factors associated with LEA...

Although generally considered to be both a durable and functional procedure for limb preservation, the transmetatarsal amputation (TMA) has high rates of complication, failure, revisional operation, and progression to more proximal amputation. The objective of this investigation was to determine the effect of remnant metatarsal parabola structure on healing outcomes following TMA. A retrospective chart review was performed of subjects undergoing a complete TMA with primary closure. We considered 4 patterns of remnant metatarsal parabola structure...

In limb and life-threatening diabetic foot infections, transmetatarsal amputations are often indicated as a limb salvage procedure. The aim of this study is to analyze the long-term durability of initially successful transmetatarsal amputations in the diabetic population. We defined a successful transmetatarsal amputation as one which had clinical healing 1 year after surgery. A retrospective review of transmetatarsal amputations completed at our institution over an 11-year period was performed. We identified 83 amputations that met inclusion criteria...

Ulceration or reulceration is a common complication following partial or total fifth ray amputations. The primary aim of this study was to evaluate the incidence of reulceration following partial fifth ray amputations. This was a multicenter review of 117 consecutive limbs that underwent partial fifth ray amputations at the University of Pittsburgh Medical Center and Wake Forest Baptist Medical Centers. Procedures were performed at various levels along the fifth metatarsal. Incidence of postoperative ulceration was evaluated on the ipsilateral foot...

Medical literature offers no clear treatment guidelines when performing amputations for gangrene of the forefoot despite a high percentage that suffer poor outcome due to infection. Gas gangrene and wet gangrene are often preceded by dry stable gangrene. This is a retrospective review of consecutive patients who underwent forefoot amputation and bone biopsy as treatment of forefoot gangrene by a single surgeon. Procedures performed included digital, ray, or transmetatarsal amputation with bone biopsy sent for both culture and histopathologic evaluation...

BACKGROUND: Chronic limb-threatening ischaemia (CLTI) in cases where there are no further standard treatment options for limb salvage represents the most advanced stage of peripheral arterial disease. For these "no-option" CLTI patients, an experimental treatment of foot vein arterialisation (FVA) was first described in 1912, however, it was never widely adopted as outcomes varied significantly most likely due to the complexity of the surgical intervention and lack of standardisation...

BACKGROUND: The choice of incident amputation level can have a profound effect on clinical outcomes. Amputations at the transmetatarsal (TM) or transtibial (TT) levels result in greater preservation of function and mobility, whereas transfemoral (TF) amputations typically result in a greater adverse impact. Prior investigations have explored racial/ethnic and regional variation in incident amputation level. This study overcomes some of the methodological limitations seen in prior research through the use of a large national, multiyear veteran sample and by including only those who have undergone an incident amputation...

OBJECTIVE: Prediction of amputation wound healing is challenging due to the multifactorial nature of critical limb ischemia and lack of objective assessment tools. Up to one-third of amputations require revision to a more proximal level within one year. We tested a novel wound imaging system to predict amputation wound healing at initial evaluation. METHODS: Patients planned to undergo amputation due to critical limb ischemia were prospectively enrolled. Clinicians evaluated the patients in traditional fashion and all clinical decisions for amputation level were determined by the clinician's judgement...

Objective: In this study, we seek to identify patient characteristics associated with limb loss and mortality while exploring the potential impact a multidisciplinary care team may have. Approach: This was a 10-year retrospective review of patients presenting to our tertiary care center for limb salvage with a diagnosis of lower extremity (LE) necrotizing fasciitis (NF). Patient demographics, clinical history, and outcomes were compared between survivors and nonsurvivors and between those who underwent LE amputation and those who did not...

The objective of this investigation was to evaluate short-term adverse outcomes following forefoot amputation with a specific comparison between those procedures performed on an inpatient versus outpatient basis. The 2018 American College of Surgeons National Surgical Quality Improvement Program database was interrogated to select those subjects with a 28805 current procedural terminology code (amputation, foot; transmetatarsal) that underwent the procedure with "all layers of incision (deep and superficial) fully closed...
