Balance confidence among people with lower-limb amputations.
(9/333)
BACKGROUND AND PURPOSE: Confidence in a person's balance has been shown to be an important predictor of social activity among people with lower-limb amputations. The purposes of this study were to describe confidence in balance among people with transtibial or transfemoral lower-limb amputations and to compare people whose amputations were due to vascular and nonvascular causes. SUBJECTS AND METHODS: A survey of a sample of 435 community-dwelling individuals from 2 regional clinics was conducted. The sample consisted of people with unilateral transfemoral (26.7%) and transtibial (73.3%) amputations who lost their limb for vascular (53%) and nonvascular (47%) reasons. The mean age of the primarily male (71%) sample was 62.0 years (SD=15.7). RESULTS: Mean scores, using the Activities-specific Balance Confidence (ABC) Scale, were 63.8 for the total sample, 54.1 for the subjects with amputations due to vascular reasons, and 74.7 for the subjects with amputations due to nonvascular reasons. Given a maximum possible ABC Scale score of 100, the results suggest that confidence was low. A difference between the subjects with amputations due to vascular reasons and those with amputations due to nonvascular reasons was observed over each item of the ABC Scale. Variables that were statistically related to balance confidence included age, sex, etiology, mobility device use, the need to concentrate while walking, limitations in activities of daily living, depression, and fear of falling. DISCUSSION AND CONCLUSION: Balance confidence scores among the study sample were low when compared with values previously reported by other researchers. Confidence was particularly low among individuals who had their amputation for vascular reasons. Balance confidence might be an important area of clinical concern. (+info)
Turn-up bone flap for lengthening the below-knee amputation stump.
(10/333)
When amputation just below the knee becomes necessary after extensive loss of bone from the tibia and of anterior soft tissue in the treatment of tumours, fractures or infection, the remaining proximal tibia may be too short for a below-knee prosthesis, although the knee may be normal. We have included the distal tibia or foot in a long posterior flap by turning it up thus increasing the length of a very short proximal tibial stump. The knee is thereby saved, allowing satisfactory use of a below-knee prosthesis. This technique is particularly applicable when the distal leg is normal and well vascularised. Five procedures have been undertaken. We present two illustrative cases. (+info)
The results of endoprosthetic replacement for tumours of the distal humerus.
(11/333)
Ten patients underwent endoprosthetic replacement of the distal humerus for bone tumours over a period of 30 years. There were eight primary and two secondary tumours in four men and six women with a mean age of 47.5 years (15 to 76). The mean follow-up was eight years (9 months to 31 years). Four patients required further surgery, three having revision for aseptic loosening; two of these and one other later needing a rebushing. There were no cases of postoperative nerve palsy, infection, local recurrence or mechanical failure of the implant. Four patients died from their disease, all with the prosthesis functioning satisfactorily. At follow-up the mean flexion deformity of the elbow was 15 degrees (0 to 35) and the mean range of lexion was 115 degrees (110 to 135). The functional results showed a mean Toronto extremity salvage score of 73% of normal. Endoprosthetic replacement of the distal humerus and elbow is a satisfactory method of treating these rare tumours. (+info)
Orthotopic and heterotopic lower leg reimplantation. Evaluation of seven patients.
(12/333)
Reimplantation is a well-established procedure in reconstructive surgery. This is especially so after amputation of the upper limb since prostheses provide limited function. In unilateral amputation of the lower leg orthotopic reimplantation is the treatment of choice. With bilateral amputation, in which orthotopic reimplantation is not possible because of the complexity of the trauma, heterotopic reimplantation is an option. We report five patients who received orthotopic and two who received heterotopic reimplantations of the lower leg. We assessed the functional outcomewith reference to cutaneous sensation, mobility, pain, and the cosmetic result. The functional outcome was good, as was the patients' satisfaction. Their mobility, stability, and psychological state were satisfactory. Patients with heterotopic reimplantations preferred the reimplanted leg to a prosthesis. Although reimplantation of the lower leg requires prolonged hospitalisation, delayed mobilisation and secondary operations, we conclude that there is an indication for this operation in order to improve the patient's quality of life.

Functional outcome in a contemporary series of major lower extremity amputations.
(13/333)
PURPOSE: We undertook this study to document the functional natural history of patients undergoing major amputation in an academic vascular surgery and rehabilitation medicine practice. METHODS: A retrospective review was conducted of consecutive patients undergoing major lower extremity amputation and rehabilitation in a university and Department of Veterans Affairs hospital. Main outcome variables included operative mortality, follow-up, survival, median time to incision healing, secondary operative procedures for wound management, and conversion from below-knee amputation (BKA) to above-knee amputation (AKA). For surviving patients, quality of life was determined by degree of ambulation, eg, outdoors, indoors only, or no ambulation; use of a prosthesis; and independence, eg, community housing or nursing facility. RESULTS: From August 1997 through March 2002, 154 patients (130 men; median age, 62 years) underwent 172 major amputations, 78 AKA and 94 BKA, because of either critical limb ischemia (87%) or diabetic neuropathy (13%). Thirty-day operative mortality was 10%. Mean follow-up was 14 months. Healing at 100 and 200 days, as determined with the Kaplan-Meier method, was 55% and 83%, respectively, for BKA, and 76% and 85%, respectively, for AKA. Twenty-three BKA and 16 AKA required additional operative revision, and 18 BKA ultimately were converted to AKA. Survival was 78% at 1 year and 55% at 3 years. Function in surviving patients at 10 and 17 months, respectively, was as follows: 21% and 29% of patients ambulated outdoors, 28% and 25% ambulated indoors only, and 51% and 46% of patients were nonambulatory; 32% and 42% of patients used prosthetic limbs; and 17% and 8% of patients who lived in the community before amputation required care in a nursing facility. CONCLUSIONS: We were surprised to find that vascular patients in a contemporary setting who require major lower extremity amputation and rehabilitation often remain independent despite infrequent prosthesis use and outdoor ambulation. Although any hope for postoperative ambulation in this population requires salvaging the knee joint, because of the morbidity incurred in both wound healing and rehabilitation efforts, aggressive effort should be reserved for selected patients at good risk. Ability to predict ambulation after BKA in the vascular population is poor. (+info)
Lower extremity amputations in chronically dialysed patients: a 10 year study.
(14/333)
BACKGROUND: Lower limb critical ischemia is a major problem in dialysed patients. OBJECTIVE: To evaluate the results of revascularization procedures, amputations and prosthetic rehabilitation in dialysed amputees. METHODS: In this retrospective study we examined the charts of selected dialysis patients. Forty-eight patients had undergone major amputation (4.5% of the dialysis population), and 24 patients entered the rehabilitation program. Widespread arterial calcification was common and led to falsely elevated ankle-brachial pressure indices in 9 of 14 limbs. Eight patients underwent revascularization. Subsequent major amputation was carried out 4 +/- 4.5 months after the revascularization (above knee in 5 patients and below knee in 3). Of the 16 patients who underwent primary amputation, only 2 were above-knee amputees. Seven patients with toe or metatarsal amputation went on to a major amputation 1.8 +/- 1.2 months after the distal amputation. RESULTS: No differences were found between diabetic and non-diabetic patients regarding the number of revascularization operations performed, the level of major amputation, or overall survival. Prosthetic rehabilitation was considered successful in 12 patients, partially successful in 8, and failed in 4 patients. Patient survival time was shortest in those patients with failed rehabilitation. A younger age confirmed favorable rehabilitation results, while long-standing diabetics and bilateral amputees were poor rehabilitation candidates. Patients who underwent primary amputation had more successful rehabilitation. A comparison between 24 dialysed amputees and 138 non-uremic amputees revealed similar rehabilitation results, although hospitalization time was longer in the dialysed patients. CONCLUSIONS: Early definitive therapy is essential when dealing with critical ischemia. After diagnostic angiography, proximal revascularization should be performed where feasible. Primary amputation is indicated in patients with extensive foot infection or gangrene. Prosthetic rehabilitation is warranted in most dialysed amputees. (+info)
Prosthesis for child amputees; the program at University of California at Los Angeles.
(15/333)
The Child Amputee Program has operated jointly for the past three years at the University of California at Los Angeles under the Department of Engineering and the School of Medicine. The following seven points have been evolved after three years of operation:1. Team effort for involved rehabilitation problems seems to be more effective than any other approach.2. Psychological effect on both the patient and family is much deeper than was realized.3. The optimum age for first fitting of a prosthesis is much earlier than had been generally believed-under one year, as opposed to age five or later.4. Training adequate for efficient and easy use of the prosthesis is absolutely essential and must be followed with periodic training in new skills.5. Comfort and function must be provided or a prosthesis will not be used.6. Scaled-down adult components are helpful, but do not supply all the needs of growing children. Special types of tools are needed for the many varied activities of childhood.7. At the outset of the program, disability was calculated in terms of the site of amputation. Now it is realized that the true determination of disability is above the ears. (+info)
Functional bracing of the upper extremity.
(16/333)
Arm bracing problems, because of their complexity, need careful evaluation by a team of interested specialists in the field of medicine, physical therapy, occupational therapy, orthotics or prosthetics. The patient must always be a working member of this team. If the basic principles of evaluation, fabrication and training are followed and the motivation is good, success with specific goals may be expected.A few arm brace situations as they reflect special problems are discussed in the hope of stimulating more interest in this fascinating field.
