Zygomycosis is the third leading cause of invasive fungal infection after candidiasis and aspergillosis. Although zygomycosis mostly affects immunocompromised individuals trauma may potentiate infection in immunocompetent individuals. The mortality rate of Zygomycosis is around 50% due to angioinvasion. Here we report a series of 5 cases of angio invasive fungal infection in immunocompetent individuals who sustained trauma in urban areas, out of which only one patient survived following high above knee amputation...

BACKGROUND: Necrotising fasciitis (NF) is a severe, devastating soft tissue infection characterised by rapidly progressing tissue necrosis. This rare condition has a high mortality rate and poses diagnostic and management challenges to the clinician. There is usually a history of trauma, which maybe trivial. Some of the premorbid conditions associated with NF are diabetes and or immunocompromised state. It requires prompt recognition and early treatment with intravenous antibiotics and extensive surgical debridement...

Regular use of prostheses is critical for individuals with lower limb amputations to achieve everyday mobility, maintain physical and physiological health, and achieve a better quality of life. Use of prostheses is influenced by numerous factors, with prosthetic design playing a critical role in facilitating mobility for an amputee. Thus, prostheses design can either promote biomechanically efficient or inefficient gait behavior. In addition to increased energy expenditure, inefficient gait behavior can expose prosthetic user to an increased risk of secondary musculoskeletal injuries and may eventually lead to rejection of the prosthesis...

Periprosthetic infection via skin-implant interface is a leading cause of failures and revisions in direct skeletal attachment of limb prostheses. Implants with deep porosity fabricated with skin and bone integrated pylons (SBIP) technology allow for skin ingrowth through the implant's structure creating natural barrier against infection. However, until the skin cells remodel in all pores of the implant, additional care is required to prevent from entering bacteria to the still nonoccupied pores. Temporary silver coating was evaluated in this work as a means to provide protection from infection immediately after implantation followed by dissolution of silver layer in few weeks...

OBJECTIVE: Through-knee amputation (TKA) is a rare amputation performed in <2% of all major lower extremity amputations in the United States. Despite biomechanical benefits and improved rehabilitation compared with above-knee amputation (AKA), TKA has largely been abandoned by vascular surgeons because of concerns for poor wound healing. The purpose of this study was to evaluate surgical outcomes of TKA. METHODS: The American College of Surgeons National Surgical Quality Improvement Program between 2005 and 2012 was queried using Current Procedural Terminology codes indicating AKA and TKA...

Low-grade central osteosarcoma (LGCO) is a rare subtype of osteosarcoma, constituting < 2% of all osteosarcomas. If not treated appropriately, the tumor can recur with higher-grade disease. We report two cases of low-grade central osteosarcoma with unusual morphologic features and belonging to different age groups. Both presented with pain and swelling in the lower end of femur. Radiologically, both the lesions revealed a large mass with irregular borders and soft tissue invasion. One patient underwent above-knee amputation and wide local excision of tumor was done in the other patient...

OBJECTIVE: Major lower extremity amputations (MLEAs) remain a significant source of disability. It is unknown whether postamputation functional outcomes and outcome predictability have changed with a population of increasingly aging and obese patients. Accordingly, we sought to evaluate contemporary trends. METHODS: A retrospective chart review was performed to identify patients undergoing MLEA using Current Procedural Terminology codes in a university hospital...

OBJECTIVES: To date, studies of vascular amputees primarily examine quantitative outcomes following limb loss. Less is known about the patient's perspective after major lower limb amputation. Here, we define and describe the postamputation recovery period. METHODS: Qualitative study using purposive, maximum variation sampling on the variables of amputation level and times since surgery. We first conducted structured interviews with 20 participants (median age: 65 years, range: 45-88 years; 85% male; below knee amputation n = 14; above knee amputation n = 6; median time from amputation to interview = 16 months, range: 4-51 months)...

RATIONALE: Although lower-extremity surgeries are mainly performed under general or central neuraxial anesthesia, ultrasound-guided peripheral nerve block (PNB) can be a good alternative, especially for patients who require continuous anticoagulation treatment and present with poor cardiovascular conditions. PATIENTS CONCERNS: The patient required continuous anticoagulation treatment due to the high risk of thromboembolism and poor cardiovascular conditions. DIAGNOSES: The patient required lower-extremity amputation due to atherosclerotic and thromboembolic obstruction...

Acute arterial occlusion is a rare complication following total knee arthroplasty (TKA). This is a report of a case of acute femoral artery occlusion and its sequelae following TKA in a patient with a history of atrial fibrillation. Arterial circulation of the lower limb could not be restored by thrombectomy treatments, and above-knee amputation had to be carried out.

In 16 years of conflict, primarily in Iraq and Afghanistan, wounded warriors have primarily been subjected to blast type of injuries. Evacuation strategies have led to unprecedented survival rates in blast-injured soldiers, resulting in large numbers of wounded warriors with complex limb trauma. Bone and soft tissue defects have resulted in increased use of complex reconstructive algorithms to restore limbs and function. In addition, in failed salvage attempts, advances in amputation options are being developed...

BACKGROUND: Free tissue transfer is one option for preservation of form and function in the native limb, in the setting of soft tissue paucity. However, the data on patient functionality after microvascular intervention is inconsistently reported. The Lower Extremity Function Scale (LEFS) measures patient-reported difficulty in carrying out 20 physical activities, on a Likert scale, the sum of which correlates with descriptive functional stages of 1-5. We assess limb functionality in this cohort of microvascular patients using the LEFS survey...

BACKGROUND: Patients presenting with both chronic periprosthetic joint infection (PJI) and extensor mechanism disruption (EMD) pose a significant challenge. As there is little in the literature regarding outcomes of patients with concomitant PJI and EMD, we performed a multicenter study to evaluate the outcomes. METHODS: Sixty patients with concomitant diagnoses of PJI and EMD were evaluated from 5 institutions. Patient demographics, presentation type, surgical management, and outcomes including recurrent infections, final surgery, and ambulatory status were documented...

REVIEW
Graeme K Ambler, Christopher P Twine
BACKGROUND: Femoro-popliteal bypass is implemented to save limbs that might otherwise require amputation, in patients with ischaemic rest pain or tissue loss; and to improve walking distance in patients with severe life-limiting claudication. Contemporary practice involves grafts using autologous vein, polytetrafluoroethylene (PTFE) or Dacron as a bypass conduit. This is the second update of a Cochrane review first published in 1999 and last updated in 2010. OBJECTIVES: To assess the effects of bypass graft type in the treatment of stenosis or occlusion of the femoro-popliteal arterial segment, for above- and below-knee femoro-popliteal bypass grafts...

PURPOSE: We report the oncological and functional results of limb salvage for bone sarcomas involving the distal tibia using hybrid surgical technique of resection arthrodesis by bone transport then plating. METHODS: Five patients (mean age 18.6 years) with primary distal tibial sarcomas (two Ewing's sarcomas and three osteosarcomas) were treated by this method. The average duration of follow-up is 53 months. All patients accepted distraction osteogenesis with a standard technique using external fixator after wide (four cases) or marginal (one case) resection in the first operation...

BACKGROUND: There are many studies that have investigated biomechanical differences among prosthetic feet, but not changes due to adaptation over time. There is a need for objective measures to quantify the process of adaptation for individuals with a transtibial amputation. Mechanical power and work profiles are a primary focus for modern energy-storage-and-return type prostheses, which strive to increase energy return from the prosthesis. The amount of energy a prosthesis stores and returns (i...
