The Krukenberg procedure: a surgical option for the treatment of double hand amputees in Sierra Leone.

BACKGROUND: For the past 9 years, Sierra Leone has struggled with a cruel civil war in which the civilian population has been the principal target. The International Committee of the Red Cross established a surgical mission in Netland Hospital, Freetown, and during this surgical mission, we treated crippled individuals who had had one or both hands amputated. We assessed the benefit of the Krukenberg procedure to restore manual dexterity in this group. In this operation, radius and ulna are separated and a pincer-like grasp is created. METHODS: From July 15, 1998, to Sept 9, 1998, we carried out the Krukenberg procedure on a group of double and single hand amputees. The main target group was double hand amputees, however, the procedure was initially done on three single hand amputees to assess the functional result. Between the original trauma and the operation, there had been an interval of 3 months or longer in all patients. Patients were followed up for 3 months after the procedure to assess gripping strength and self-sufficiency (feeding, personal hygiene, dressing, and manual dexterity). FINDINGS: 15 Krukenberg procedures were done on 11 patients: eight men and three women (mean age 42 years). Three had single hand amputation and eight had double hand amputation. In only two patients had sufficient time passed for the stumps to heal. Of ten patients who were followed up at 3 months, all could eat and drink by themselves. The simple dressing test was passed by all patients and 75% of the patients had recovered some dexterity. INTERPRETATION: The Krukenberg procedure is a surgical option to achieve some manual dexterity in double hand amputees, where resources for sophisticated hand prostheses are lacking.

Phantom pain and phantom sensations in upper limb amputees: an epidemiological study.

Phantom pain in subjects with an amputated limb is a well-known problem. However, estimates of the prevalence of phantom pain differ considerably in the literature. Various factors associated with phantom pain have been described including pain before the amputation, gender, dominance, and time elapsed since the amputation. The purposes of this study were to determine prevalence and factors associated with phantom pain and phantom sensations in upper limb amputees in The Netherlands. Additionally, the relationship between phantom pain, phantom sensations and prosthesis use in upper limb amputees was investigated. One hundred twenty-four upper limb amputees participated in this study. Subjects were asked to fill out a self-developed questionnaire scoring the following items: date, side, level, and reason of amputation, duration of experienced pain before amputation, frequencies with which phantom sensations, phantom pain, and stump pain are experienced, amount of trouble and suffering experienced, respectively, related to these sensations, type of phantom sensations, medical treatment received for phantom pain and/or stump pain, and the effects of the treatment, self medication, and prosthesis use. The response rate was 80%. The prevalence of phantom pain was 51%, of phantom sensations 76% and of stump pain 49%; 48% of the subjects experienced phantom pain a few times per day or more; 64% experienced moderate to very much suffering from the phantom pain. A significant association was found between phantom pain and phantom sensations (relative risk 11.3) and between phantom pain and stump pain (relative risk 1.9). No other factors associated with phantom pain or phantom sensations could be determined. Only four patients received medical treatment for their phantom pain. Phantom pain is a common problem in upper limb amputees that causes considerable suffering for the subjects involved. Only a minority of subjects are treated for phantom pain. Further research is needed to determine factors associated with phantom pain.

Phantom limb sensations and phantom limb pain in child and adolescent amputees.

OBJECTIVE: To provide a better understanding of the prevalence, correlates and quality of phantom sensations and phantom pain in child and adolescent amputees. DESIGN: Retrospective survey study. SETTING: Recruitment through the War Amputations of Canada. PARTICIPANTS: Sixty child and adolescent amputees aged 8-18 years who were missing a limb due to a congenital limb deficiency (n = 27) or surgery/trauma (n = 33). MAIN OUTCOME MEASURE(S): Questionnaire to assess the occurrence and correlates of phantom sensations and phantom pain. RESULTS: Forty-two percent of the total sample reported phantom sensations; 7.4% of the congenital group and 69.7% of the surgical group (chi2 = 23.70 with 1 df, P < 0.01.) Twenty-nine percent of the total sample reported phantom pain; 3.7% of the congenital group and 48.5% of the surgical group (chi2 = 14.67, with 1 df, P < 0.01). Eighty-eight percent of the amputees with phantom pain had stump pain, while 35.3% had phantom pain that was similar to pre-operative pain and 76.5% experienced pains other than phantom pain (e.g. headaches). Amputees identified exercise, objects approaching the stump, cold weather and 'feeling nervous' as the primary triggers of phantom sensations and/or phantom pain. CONCLUSION(S): Less than half of the sample experienced phantom sensations and phantom pain; however, the loss of a limb due to surgery is associated with an increase in the likelihood of experiencing these phenomena.

Psychological distress in amputees with phantom limb pain.

Research suggesting that psychological factors play a role in phantom limb pain abounds in the literature. Despite recent research suggesting that these factors exacerbate rather than cause phantom limb pain, clinicians still frequently use personality as a rationale to explain amputees' phantom limb pain. The present study aimed to examine psychological distress in a working-age population of amputees not specifically seeking help for their pain. The study was conducted in two phases. Phase 1 included 315 amputees who completed the General Health Questionnaire (GHQ). Phase 2 included a subset of the original sample who completed the Beck Depression Inventory (BDI). In Phase 1, although over 50% of the sample reported GHQ scores over the threshold used to detect "caseness," this was not related to phantom limb pain. In Phase 2 of the study, only 15% of the sample reported moderate to severe symptoms of depression. Only 4% of the variance in phantom limb pain was accounted for using the overall BDI score. When BDI items were examined individually within regression models, a number significantly predicted phantom limb pain. However, the items most related to phantom limb pain were those involved in "performance difficulties" rather than "negative affect." The present study suggests that negative affect in amputees may be related to disability rather than pain.

Phantom pain and health-related quality of life in lower limb amputees.

Amputation of a limb may affect quality of life. However, little is known concerning health-related quality of life in amputees. The purposes of this study were to describe health-related quality of life in a population of lower limb amputees and to investigate potential determinants, including phantom pain. Data from 437 patients with a lower limb amputation were analyzed in this cross-sectional study. Amputation-related problems were investigated using a questionnaire. Health-related quality of life was investigated using the RAND-36 DLV. Amputees with phantom pain had a poorer health-related quality of life than amputees without phantom pain. In general, the most important amputation-specific determinants of health-related quality of life were "walking distance" and "stump pain."

Nursing's role with amputee support groups.

An amputee support group is integral to holistic health care. A support group provides opportunities for peers and interdisciplinary team members to meet the unique needs of amputees. Nurses have an opportunity to be involved in the initiation and facilitation of an amputee support group within a health care agency or community. The purpose of this article is to discuss the role of nursing in developing an amputee support group.

Evaluating a written emotional disclosure homework intervention for lower-limb amputees.

OBJECTIVE: To evaluate the Pennebaker Emotional Disclosure paradigm with lower-limb amputee patients in terms of compliance and efficacy. DESIGN: Repeated measures. SETTING: Home based. PARTICIPANTS: Low compliance, both with the initial mailed request (28%) and the subsequent writing task (48%), resulted in 23 lower-limb amputees who had been fitted with a prosthesis participating. INTERVENTIONS: Patients completed a 15-minute writing task, 6 times, over 2 weeks, with initial baseline and 2-month follow-up assessments. MAIN OUTCOME MEASURES: Cognitive processing, well-being, adjustment to an artificial limb, pain, and prosthetic use. RESULTS: Stronger emotional disclosure was associated with significant reductions in psychologic and physical aspects of amputees' satisfaction with their prosthesis, some of which were mediated by positive changes in affect immediately after the writing tasks. CONCLUSIONS: Our results failed to support previous findings with nonclinical samples; in fact, our results contradicted previous findings. We therefore caution that written emotional disclosure may be contraindicated with lower-limb amputee patients.

Lower-leg inertial properties in transtibial amputees and control subjects and their influence on the swing phase during gait.

OBJECTIVES: To identify the factors that constitute optimal inertial properties for a lower-limb prosthesis. DESIGN: Experimental, controlled; simulation using a subject-specific double-pendulum model based on individual kinematic data and leg inertial properties. Simulation outcomes were compared with gait analysis data. SETTING: A gait laboratory. PARTICIPANTS: Ten transtibial amputees and 10 matched healthy controls. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Inertial properties of the lower leg; kinematics and kinetics of the swing phase; and kinematics of double-pendulum model simulations. RESULTS: In all amputees, inertial properties were reduced. No between-group differences existed in kinematics; hip and knee joint torques and powers were reduced in the amputees. Deviations between the double-pendulum model and experimental data were larger in the amputees than in the control subjects. CONCLUSIONS: Although current lightweight prostheses have less optimal pendular behavior, their light weight requires smaller joint torques to influence the pendular trajectory. Therefore, optimal inertial properties, in terms of swing phase kinematics and kinetics, will be a compromise between pendular properties and efficient control.

Left and right hand recognition in upper limb amputees.

Previous research suggests a close similarity in brain activity between mental simulation of a movement and its real counterpart. To explore this similarity, we aimed to assess whether imagery is affected by the loss of a limb or of its motor skills. We examined the performance of 16 adult, upper limb amputees (and age-matched controls) in a left/right hand judgement task that implicitly requires motor imagery. The experimental group included subjects who had suffered the amputation of the dominant or the non-dominant limb. Although responding well above chance, amputees as a group were slower and less accurate than controls. Nevertheless, their response pattern was similar to that of controls, namely slower response times and more errors for stimuli depicting hands in unnatural orientations, i.e. postures difficult to reach with a real movement. Interestingly, for all stimuli, amputees' performance was strongly affected by the side of limb loss: subjects who underwent amputation of their preferred limb made more errors and required greater latencies to respond as compared with amputees of the non-dominant limb. In a further analysis we observed that the habit of wearing an aesthetic prosthesis significantly interfered with the ability to judge the corresponding hand. Our data lead to three main conclusions: (i) loss of a single limb per se does not prevent motor imagery but it significantly enhances its difficulty; (ii) these subjects apparently perform the hand recognition task using a strategy in which they initially mentally simulate movements of their dominant limb; (iii) wearing a prosthesis, devoid of any motor function, seems to interfere with motor imagery, consistent with the view that only 'tools' can be incorporated in a dynamic body schema.

Persistent hand motor commands in the amputees' brain.

The loss of a limb leads to sensorimotor modifications that are frequently accompanied by the vivid experience that the missing limb is still present, and that it can be moved at will. Furthermore, amputees can clearly distinguish between phantom movements of the fingers and of more proximal joints, like movements of the elbow. This phenomenon raises the question of whether these specific phantom movement experiences are translated into differentiated activity within the remaining muscles. We recorded stump muscle activity when above-elbow amputees voluntarily moved their phantom limb. Voluntary movements of the phantom hand triggered specific patterns of stump muscle activity, which differed from activity recorded in the same muscle groups during movements of the proximal limb. This result indicates that the brain's motor areas can be differentially activated according to the phantom movement the patient intends to perform, and suggests that hand motor commands are preserved after amputation. To further understand the interaction between central commands and sensory feedback in the perception of phantom movement we also measured stump muscle EMG activity in an amputee experiencing a frozen phantom limb, and in three below-elbow amputees with vivid phantom movements after inducing an ischaemic block. Failed attempts to move the paralysed phantom limb always resulted in the same EMG pattern, no matter what type of phantom movement was attempted, while ischaemic nerve block reduced or eliminated the ability to voluntarily move the phantom limb and produced a dramatic reduction in the amplitude of stump muscle EMG activity. Our data suggest that the experience of phantom hand movement involves the activation of hand motor commands. We propose that preserved hand movement representations re-target the stump muscles to express themselves and that when these representations are voluntarily accessible they can instruct the remaining muscles to move in such a way as if the limb is still there.

The performance of the ICEROSS prostheses amongst transtibial amputees with a special reference to the workplace--a preliminary study. Icelandic Roll on Silicone Socket.

A clinical trial was conducted to evaluate the efficiency of ICEROSS on randomly selected 46 male transtibial amputees. After rejection, only 27 (58.69%) amputees volunteered for various stages of the ICEROSS trial. All 27 were categorized into Group A-persons in employment (n = 16) and Group B-persons out of employment or economically inactive (n = 11). The study was conducted on the basis of questionnaire information, clinical examination and objective tests. The pre- and post-ICEROSS status were compared between the groups. Group A was younger and did better. Trauma was the main cause of amputation. There were certain changes of the stump before and after ICEROSS. The amputees with ICEROSS suspension performed better and had improved mobility in Group A. At the workplace, dynamic activities were less than the static activities (p < 0.001) and there were overall improvements in comfort and performance of amputees with ICEROSS.

Evaluation of amputees.

During 1978 the Queen Alia Fund registered all disabled persons in the East Bank of Jordan. This paper is intended to investigate the actual condition of a sample selected from those persons registered as amputees. The registration showed a total of 696 amputees and a sample of 100 patients was randomly selected from this group. This study explored the disability, its nature and location, physical and vocational rehabilitation received, and the functional capability of the amputee. The two most important causes which lead to the amputation were mine explosions and road accidents. 32 persons received physical rehabilitation and prosthesis was recommended for 56 persons. Only 9 patients received vocational rehabilitation. Final analysis of the data showed steady increase in the past two decades with a doubling of the number from the 1960s to the 1970s. Road accidents played a major role in this increase. It is interesting to note that males and educated persons tend to use their prosthesis more than females and illiterate persons. In conclusion vocational rehabilitation remains an important element missing from the management of amputees. More emphasis and effort should be directed toward this element in order to complete the picture of an effective rehabilitation of this group of disabled persons.

Long-term follow-up of Iranian veteran upper extremity amputees from the Iran-Iraq war (1980-1988).

BACKGROUND: Despite their frequency, there are limited reports concerning long-term follow up of upper limb amputation among battle-injured patients, which occurred at a young age. The purpose of this study was to evaluate how well these patients function years after their injury. METHODS: The study consisted of a thorough assessment and examination and review of the history and war time medical records of 25 Iranian veteran amputees from imposed Iran-Iraq war with a comprehensive survey including a detailed questionnaire. Information was analyzed and compared with limited similar reports in the literature. RESULTS: Out of 200 war amputees there were 25 unilateral upper limb amputees; all others were lower limb amputees. The average age at the time of injury was 23.06 years, average age at follow-up was 41.55 years, and the average time between injury and follow-up was 17.5 years. The most common level of amputation was below elbow (40%), and the most common cause of war injury was artillery shells, mortar or rocket shells. The prevalence of clinical symptoms of phantom sensation, phantom pain, phantom movement and stump pain were; 64%, 32%, 20%, 24%, respectively. All patients were married (100%) and had children except one case (96%). Sixty percent of patients were employed. Thirty-six percent had a documented psychiatric history ranging from minor depression to posttraumatic stress disorders. CONCLUSION: The study showed-despite long period of time between war, amputation, and follow-up-there is a significant rate of amputation symptoms, but on the other hand good family and social function of the patients.

Preventing falls and stump injuries in lower limb amputees during inpatient rehabilitation: completion of the audit cycle.

OBJECTIVES: To study the factors contributing to falls among recent lower limb amputees, and to reduce the number of falls during inpatient rehabilitation and resulting injuries. DESIGN: Retrospective, followed by prospective, cohort study, then a follow-up study conducted after interventions. SETTING: Twenty-bedded inpatient rehabilitation unit for amputees. SUBJECTS: Lower limb amputees. INTERVENTIONS: Patient education, environmental modifications and application of a bivalve plaster of Paris stump protector to patients who were aged 70 or over, or cognitively impaired. MAIN OUTCOME MEASURES: Numbers of falls and other accidents, and resulting injuries. RESULTS: In phase 1 of the study, a retrospective audit of incident forms that had been completed on lower limb amputees who had an accident during their inpatient rehabilitation, between 1 April 1996 and 31 Ocotber 1998, was carried out. This showed that approximately a third of admissions (32%) were complicated by an accident. Most accidents were falls. In phase 2, a prospective study of 113 patients admitted to the unit was undertaken. Patients who fell were significantly older than those who did not. In phase 3, 62 consecutive patients were studied. There were 37 accidents in total, of which 35 were falls. Compared with the phase 2 study, there was no reduction in the proportion of patients who had a fall or other accident in phase 3, but significantly fewer falls resulted in any injury (p = 0.05). CONCLUSIONS: Although the interventions employed did not reduce the proportion of patients who had falls or other accidents, significantly fewer falls resulted in injuries.

Energy expenditure of below-knee amputees during harness-supported treadmill ambulation.

Traditional rehabilitation of amputees is primarily aimed at strengthening remaining musculature necessary for prosthetic use and gait training. Available gait training time, however, is often limited by pain, residual limb skin tolerance, and the patient's cardiovascular endurance. Harness-supported treadmill ambulation is a rehabilitation technique being used by physical therapists to decrease an individual's body weight by a given percentage during exercise. This, theoretically, allows an amputee to ambulate on a prosthesis at a lower energy cost. The purpose of this study was to compare the energy expenditure of healthy below-knee amputee volunteers with healthy able-bodied volunteers during harness-supported treadmill ambulation in order to determine if energy conservation is achieved. Subjects were tested on a treadmill, walking at .67 m/sec (1.5 mph) and 1.34 m/sec (3.0 mph) during each of the following randomized harness-supported treadmill ambulation situations: full body weight, 20% body weight supported, and 40% body weight supported. During the last minute of each trial, rate of perceived exertion, heart rate, and standardized indirect calorimetry oxygen consumption (VO2, ml/kg/min) measures were collected. Caloric expenditure (kl/min) was calculated using metabolic conversion equations. Peak heart rate, peak VO2, and peak kl/min were measured after the conclusion of the last walking trial by taking each subject to volitional fatigue. Data were analyzed for each harness-supported treadmill ambulation situation and group using analysis of variance (ANOVA). The researchers identified significantly lower ratings of perceived exertion, heart rates, and VO2s for able-bodied subjects vs. below-knee amputees for all trials. Both groups demonstrated significantly lower heart rates, VO2s, and kl/min at 1.34 m/sec with 40% body weight supported.(ABSTRACT TRUNCATED AT 250 WORDS)

Prostheses, pain and sequelae of amputation, as seen by the amputee.

Results of a survey of 19 organizations belonging to World Veterans Federation indicate that major complains of amputees include; poor fitting, poor dissemination of knowledge to doctors and amputees regarding new prostheses, lack of opportunity for "input" from amputees at research level and inadequate measures to deal with phantom and stump pain. Suggested improvements by amputees; decrease in weight of prostheses, reduction in maintenance for swing and stance-phase control units development of recreational prostheses, more frequent checks through use of X-ray and film techniques, particularly during the "break-in" of a new appliance. Older veterans showed increasing concern in regard to development of consequential disabilities arising from amputation; premature arthritic changes in spine and remaining limb, circulatory problems and gastro-intestinal problems due to ingestion of drugs to control pain.

Functional capabilities of lower limb amputees.

Five hundred lower limb amputees were evaluated by personal interview at the Artificial Limb Centre, Pune, India. Information thus obtained on activities of daily living and functional capabilities with their prostheses was analysed. The analysis showed that 55% of the amputees were totally independent, 40% had to use a crutch or cane and only 5% were solely dependent on a wheelchair for ambulation. Further, it was also confirmed that as age increased, functional independence decreased, and that below-knee amputees were more independent than above-knee and bilateral amputees. When compared with reports of other workers from the developed countries, the results were equally good, and in some functions, were even better.

Body sway in below-knee amputees.

The purpose of the present study was to test the hypothesis that below-knee amputees have less standing stability than normal persons. Twenty below-knee amputees were tested with the quantified Romberg test. All amputees below 59 years and all women above 59 years had a decreased sway compared with matched control groups of normal persons. Amputated men above 59 years did not show any difference in sway compared with the matched control group. Presuming that small sway excursions can be interpreted as a stable standing position, the study shows that a well fitted PTB-amputee stands at least as safely as a normal person.
