Interdisciplinary treatment of diabetic foot wounds in the elderly : Low risk of amputations and mortality and good chance of being mobile with good …
2016
Aims: A major proportion of patients with diabetic foot syndrome are older than 65 years. Little is known about outcomes of these elderly patients. Methods: We analysed 245 treatment cases in an observational single-centre study for comorbidities and outcomes over a 6-month period. Results: In all, 122 patients had peripheral arterial disease which was significantly increasing with age ( n = 245, df = 1, χ2 = 23.06, p ⩽ 0.0001). Increasing age correlated positively with decreasing rate of revascularisations ( n = 122, df = 1, χ2 = 4.23, p = 0.039). In total, 23 (9.3%) patients died in the observation period. In-hospital mortality was 2.8%, percentage of major amputations 2.8%. In the invasi…
The impact of Syme amputation in surgical treatment of patients with diabetic foot syndrome and Charcot-neuro-osteoarthropathy
2002
Charcot-neuro-osteoarthropathy with its severe destruction of bones remains a challenge for physicians and surgeons. The aim of the study was to characterise a patient population treated in a specialised foot care centre who underwent surgical treatment for their diabetic foot syndrome. Special attention was paid to patients who suffered from Charcot-neuro-osteoarthropathy and the impact of Syme amputation if amputation of the foot was inevitable. A total of 121 patients with diabetic foot syndrome and ulcerations underwent an interdisciplinary strategy for diagnostic and therapeutic procedures including MRI and surgical interventions. If peripheral arterial vessel disease was present, reva…
Three-year (2014-2016) activity report of the Replantation Service for hand amputations in Poland
2018
W pracy przedstawiono podsumowanie 32 miesięcy działalności Serwisu Replantacyjnego dla amputacji rąk w Polsce od stycznia 2014 roku do sierpnia 2016 roku. W analizowanym czasie zgłoszono łącznie 568 przypadków – amputacji, częściowych amputacji i innych rozległych urazów kończyn górnych, z czego zaakceptowano 354 przypadki (62%), a odrzucono 214 (38%). Wśród 354 wszystkich zaakceptowanych przypadków znalazło się 167 całkowitych amputacji (47%), 142 amputacji niecałkowitych (40%) i 45 (13%) innych ciężkich urazów, które zagrażały utratą kończyny. W większości ofiarami byli mężczyźni o średniej wieku 39 lat. Najwięcej pacjentów przeszło amputacje kilku palców i kciuków – łącznie 229 (65%) os…
Influence of the level of arterial resection on the replanting and revascularization results in hand surgery: prospective study over 22 months
2021
Abstract The objective of this work was to assess whether the injury mechanisms are responsible for histological arterial lesions. This prospective single-center study included adults with wrist or hand arterial injury. Arterial resection of at least 2 mm from the proximal and distal stumps was performed before the arterial anastomosis. Histological analysis of the arterial stumps was performed. An ultrasound was performed 1 month postoperatively to check arterial patency. A clinical and functional evaluation was done at 1 month postoperative, then every 3 months. From 2018 to 2020, 46 patients were included with a maximum follow-up of 13 months. There were 35 cuts, 2 crush injuries, 8 ampu…
Change in take-off elevation angle after limb autotomy mitigates the reduction in jumping distance in rice grasshoppersOxya yezoensis
2013
Autotomy is the ability to spontaneously self-amputate a limb or other appendage, often as a reflexive action. This limb amputation typically occurs as a specialized defensive response to an attack from a predator and thereby enables the prey to escape from predation. Despite the benefits of escape, autotomized organisms lose the body part and its associated function. Here, we investigated the jumping behavior and performance of one-leg-autotomized and intact rice grasshoppers, Oxya yezoensis, to examine changes in jumping behavior after autotomy. The take-off elevation of autotomized grasshoppers was 7.8° lower than in intact grasshoppers, resulting in nearly a 45° angle of take-off, which…
Body composition characteristics and body surface area
2013
Chemotherapy dose calculation for oncologycal patient is using the human body surface area (BSA). BSA is a variable with a difficult constitutional body and physiological assessment. BSA does not reflect the exercise on body composition in relation to the various body modifications: obesity, amputation of body parts, pregnancy. Body surface area despite the documented limitations remains the most commonly used parameter chemotherapy (cytotoxic therapy) of cancer patients. The new guidelines are intended obese patients is to achieve the same maximum dose rate calculated BSA taking into account the full weight rather than using the statement or reduce weight by restricting intake. Experience …
Cross-cultural validation of the Prosthesis Evaluation Questionnaire in vascular amputees fitted with prostheses in Spain
2016
The lack of specific prosthetic-related outcome instruments for Spanish amputees must be addressed.To elaborate a culturally equivalent version of the Prosthesis Evaluation Questionnaire in the Spanish language.Cross-cultural questionnaire validation.Two-step process for cultural adaptation: forward and backward translations of English original and Spanish translated versions; assessment of both construct and criterion validity and reliability in a group of vascular amputees.A total of 61 patients were recruited, 44 men (72.1%) and 17 women (27.9%), with a median age of 71.1 years (standard deviation: 7.7 years; range: 51-87 years). In the Prosthesis Evaluation Questionnaire-Spanish, the lo…
Prosthetic design and prototype development
2020
Abstract In recent years, there has been worldwide interest in improvement of the mobility of people with lower-limb amputations. Despite significant development of new technologies over the last decade, commercial below-knee and above-knee prostheses are still energetically passive devices. However, many locomotive functions, like walking up stairs and slopes, need significant power in the knee and ankle joints. The additional power for carrying out these previously mentioned activities needs to be achieved by means of external energy sources, which should be integral prosthetic components. This chapter presents preliminary investigations and development towards an active robotic prosthesi…
SmartLeg: An intelligent active robotic prosthesis for lower-limb amputees
2011
In recent years, there has been a worldwide interest in improvement of mobility of people with lower limb amputation. In spite of significant development of new technologies during the last decade, commercial below-knee and above-knee prostheses are still energetically passive devices. However, many locomotive functions, like walking up stairs and slopes, need significant power in knee and ankle joints. The additional power for doing previously mentioned activities needs to be achieved by means of external energy sources, which should be integral prosthetic components. This paper presents preliminary investigations towards an active robotic prosthesis that could potentially enable people wi…
Extremitätenerhalt durch pedalen In-situ-Bypass beim diabetischen Fußsyndrom
2003
INTRODUCTION: Treatment of the ischemic diabetic foot syndrome still represents a medical and economic challenge. Contrary to the aims of the Saint Vincent declaration a dramatic reduction of major amputations in Germany was not noted, although in the diabetic patients the predominant type of tibial artery occlusion allows construction of pedal bypasses for limb salvage. METHOD: In patients with ischemic diabetic foot syndrome following angiographic evaluation of the ischemic limb, the indication for surgical revascularisation of patent pedal arteries was established. The in-situ technique was preferred in the presence of a suitable ipsilateral greater saphenous vein whenever possible. Reva…
