Major trauma in young and old : What is the difference?

OBJECTIVE To evaluate the differences in mortality and long-term outcome between young and elderly patients with multiple injuries. DESIGN Retrospective and descriptive. MATERIALS AND METHODS Over a 5-year period (from January 1985 to January 1990) all the consecutive young (20 to 29 years, n = 167) and elderly (> or = 60 years, n = 121) patients with an Abbreviated Injury Scale score/Injury Severity Score of > or = 16 treated at the University Hospital Groningen (the Netherlands) were reviewed. Age, sex, mechanisms of injury, Abbreviated Injury Scale score, Injury Severity Score, mortality, duration of artificial ventilation, hospitalization, and intensive care treatment and discharge destination were analyzed. Long-term outcome was determined using the Glasgow Outcome Scale. MEASUREMENTS AND MAIN RESULTS Motorized vehicles were the leading cause of injury in both groups. Mortality in the young was lower than in the elderly (19.6% versus 38.8%); all elderly with an Injury Severity Score of > or = 50 died. Nearly all deaths in young and elderly were caused by severe brain injuries (83.8% versus 74.4%). Deaths related to multiple organ failure were not observed in the young and were rare in the elderly. The surviving young and elderly could be discharged home in equal percentages and their functional outcome 2 years after injury did not differ essentially. CONCLUSION We did not find any valid argument to treat severely injured elderly patients any differently from their younger counterparts, which implies that the increased trauma care cost is also justified for severely injured elderly.

Multiple injuries: An overview of the outcome

To measure the functional outcome we analyzed 723 consecutive patients with multiple injuries (Abbreviated Injury Scale (AIS)/Injury Severity Score (ISS) > or = 16, mean ISS 30.1) treated at the University Hospital Groningen, the Netherlands, between 1985 and 1989. Age, sex, type of accident, AIS/ISS, discharge destination, length of hospital stay and functional outcome (measured by the Glasgow Outcome Scale) are described. The patients were young (mean age 33.4 years) and 186 died (25.7%) mainly because of severe head injuries. Half of the survivors could be discharged home and 29% were transferred to a rehabilitation center. Rehabilitation centers predominantly treat patients with severe injuries of the head or neck and extremities. These injuries, together with spinal cord injuries, appeared to be responsible for the majority of permanent disabilities. Although the functional outcome deteriorated linearly with increasing AIS/ISS, the final functional result was good: in the first half year after injury there was considerable recovery; after that there was further slight recuperation. Two years after injury, 68% had mild or no disabilities, 19% were moderately disabled, and 7% severely disabled.

Long-term physical, psychological and social consequences of severe injuries

This 6 year follow-up study was designed to evaluate the long-term physical, psychological and social outcomes of severely injured patients (Injury Severity Score of greater than or equal to 16). Patients were treated at the University Hospital Groningen, the Netherlands, between January 1989 and December 1989. Outcomes were assessed using a postal questionnaire. After injury, the 55 respondents had predominantly complaints of the extremities, the spine and the head. Psychological complaints were present in 84 per cent of patients and mainly concerned fatigue, slowness and memory impairments. Despite these physical and psychological complaints, 74 per cent of patients were able to return to work and the memory succeeded in complying with job requirements. Injuries of the extremities and the spine were risk factors for failing to return to work. Social consequences were also reflected in broken marriages (6/22) and changes of leisure activities (45 per cent). On the basis of the impairments and disabilities revealed, we conclude that further improvement of the long-term outcomes of severely injured patients may be achieved by advancements in the treatment of injuries to the head, spine or extremities, comprehensive psychological support and vocational rehabilitation.

Functional outcome in patients with thoracolumbar burst fractures treated with dorsal instrumentation and transpedicular cancellous bone grafting

The aim of the study was to develop an insight into the impairments in spinal fracture patients, operatively treated with an internal fixator, and also into their ability to participate in daily living, return to work and quality of life as defined by the World Health Organization. Nineteen patients operated for a type A fracture of the thoracolumbar spine (T9–L4) between 1993 and 1998 in the University Hospital Groningen, the Netherlands, aged between 18 and 60 years, without neurological deficit were included in the study. Operative treatment consisted of fracture reduction and internal fixation using the Universal Spine System, combined with transpedicular cancellous bone grafting and dorsal spondylodesis. No ventral fusion operations, laminectomies or discectomies were done. Restrictions in body function and structure were measured on radiographs and in functional capacity tests, such as lifting tests and ergometry. Restrictions in activities were studied with the Visual Analogue Scale (VAS) Spine Score and the Roland Morris Disability Questionnaire (RMDQ). Restrictions in participation/quality of life were analysed with the Short Form 36 (SF36) and described in the return to work status. The radiological results are comparable to the literature. The reduction of the anterior wedge angle was followed by a gradual partial loss of intervertebral angle and regional angle. The maximum oxygen uptake (VO2-max) was reduced in only 8.3% of the patients. Arm and trunk lift was within the normal range in 87% and 80% of the patients respectively, but only 53% of the patients were able to perform a leg lift within the normal range. A mean RMDQ score of 4.0 positive items (SD 6.0) was found, and the mean VAS Spinal Score was 79.4 (SD 25.0), both better than in other series. No significant differences compared to the values of a comparable (healthy) age group could be identified in any variable of the SF36. A high correlation was seen between RMDQ, VAS Spine Score and the SF36 categories. No correlation was found between the anterior wedge angle and the regional angle on the one hand, and functional capacity tests or questionnaire scores on the other. Of the patients in paid employment before the trauma, 87% had returned to work at follow-up. About 50% of the patients had been obliged to change the intensity of their work or the kind of work they performed after the injury and treatment. In this matter, leg (muscle) performance seems a more important factor than overall condition (VO2-max). The results of the study indicate that patients with thoracolumbar spinal fractures without neurological deficit, treated with dorsal instrumentation, perform like healthy people 3–8 years after injury, according to the RMDQ, VAS Spine Score and SF36 results. Physical capacity tests reveal that leg (muscle) performance seems a more important factor in impairment than arm lift or overall condition.

Return to work and quality of life in severely injured patients

Background. Little is known about the long-term consequences of severe injuries in terms of return to productivity and quality of life. Methods. In this study we focused on the return to work status and quality of life in 53 severely injured patients (AIS/ISS ≥ 16, mean ISS 24, range 16 – 54), mean age 37 years, one to two years after the injury. Questions were asked concerning employment in the past and at present. Quality of life was measured by means of the Sickness Impact Profile (SIP) questionnaire. Injury-related parameters were analysed in order to study their relation with disablement. Results. Of those patients who survived their injuries, 87% had resumed their former work. Only 10% of the patients received disability benefits. A mean SIP-total score of 6.7 was found, the mean SIP-physical score was 5.9 and the mean SIP-psychosocial score was 6.9. “No disability” (SIP score ≤ 3) was found in 55% of the patients, whereas 11% of the patients reported “severe disability” (SIP score ≥ 20). Age was a significant predictor of disablement (odds ratio 1.07). The Injury Severity Score (ISS), the length of hospital stay and the number of diagnoses did not predict disablement. Conclusions. Although the results were obtained in a relatively small sample size, the return to work rate in the surviving severely injured patients appears to be excellent. The quality of life is good; the majority of patients are not disabled. Age (and not the ISS) seems to be a significant predictor of disablement.

Long-term physical, psychological and social consequences of a fracture of the ankle

The long-term physical, psychological and social outcomes of 68 patients with an ankle fracture were investigated by using a postal questionnaire 6 years after injury. Patients were treated at a level I Trauma Centre between January 1989 and December 1989. Where applicable, the outcomes were compared with the outcomes of severely injured patients who were investigated previously. Physically, the patients were suffering from problems in the extremities and the spine. Surprisingly, half of them (52 per cent) had psychological complaints due to the initial injury. Eighty-nine per cent of the patients returned to work. This result seems to be only slightly better than the return to work in severely injured patients (74 per cent). Those with an ankle fracture needed less time to return to work (3 months versus 13 months in the severely injured patients). Further social changes (marital status, leisure activities) were mostly found in the severely injured patients. Patients with an ankle fracture as well as severely injured patients are affected by long-term consequences. The differences between the two groups are not as pronounced as is generally assumed. Probably, the consequences of lesser injuries are frequently disregarded, whereas severely injured patients are doing better than expected.

Efficiency of voluntary opening hand and hook prosthetic devices : 24 years of development?

Quantitative data on the mechanical performance of upper-limb prostheses are very important in prostheses development and selection. The primary goal of this study was to objectively evaluate the mechanical performance of adult-size voluntary opening (VO) prosthetic terminal devices and select the best tested device. A second goal was to see whether VO devices have improved in the last two decades. Nine devices (four hooks and five hands) were quantitatively tested (Hosmer model 5XA hook, Hosmer Sierra 2 Load VO hook, RSL Steeper Carbon Gripper, Otto Bock model 10A60 hook, Becker Imperial hand, Hosmer Sierra VO hand, Hosmer Soft VO hand, RSL Steeper VO hand, Otto Bock VO hand). We measured the pinch forces, activation forces, cable displacements, mass, and opening span and calculated the work and hysteresis. We compared the results with data from 1987. Hooks required lower activation forces and delivered higher pinch forces than hands. The activation forces of several devices were very high. The pinch forces of all tested hands were too low. The Hosmer model 5XA hook with three bands was the best tested hook. The Hosmer Sierra VO hand was the best tested hand. We found no improvements in VO devices compared with the data from 1987.

The health-related quality of life of pediatric traffic victims.

OBJECTIVE To describe the health-related quality of life (HRQoL) of young traffic victims and to identify those children who are at high risk of a reduced HRQoL. METHODS Retrospective analysis of data obtained from a registration system and from questionnaires completed by 211 parents of young traffic victims who attended the department of traumatology in 1996 and 1997. RESULTS The overall group of young traffic victims experienced a lower HRQoL sumscore compared with the reference population (p = 0.001). A total of 48 parents (23%) attributed their childs reduced HRQoL specifically to the traffic accident. The socioeconomic status (SES) of the father (p = 0.018) and the Injury Severity Score (p < 0.001) emerged as significant predictors of traffic-related HRQoL. CONCLUSION Children of low SES parents and severely injured children are at particularly high risk of a reduced HRQoL following a traffic accident. However, not solely severely injured and hospitalized young traffic victims may suffer a diminished HRQoL but traffic-related injuries of minor or moderate severity may cause substantial problems as well.

Flexible and static wrist units in upper limb prosthesis users: functionality scores, user satisfaction and compensatory movements

BackgroundThe current study examines the relevance of prosthetic wrist movement to facilitate activities of daily living or to prevent overuse complaints. Prosthesis hands with wrist flexion/extension capabilities are commercially available, but research on the users’ experiences with flexible wrists is limited.MethodsIn this study, eight transradial amputees using a myoelectric prosthesis tested two prosthesis wrists with flexion/extension capabilities, the Flex-wrist (Otto Bock) and Multi-flex wrist (Motion Control), in their flexible and static conditions. Differences between the wrists were assessed on the levels of functionality, user satisfaction and compensatory movements after two weeks use.ResultsNo significant differences between flexible and static wrist conditions were found on activity performance tests and standardized questionnaires on satisfaction. Inter-individual variation was remarkably large. Participants’ satisfaction tended to be in favour of flexible wrists. All participants but one indicated that they would choose a prosthesis hand with wrist flexion/extension capabilities if allowed a new prosthesis. Shoulder joint angles, reflecting compensatory movements, showed no clear differences between wrist conditions.ConclusionsOverall, positive effects of flexible wrists are hard to objectify. Users seem to be more satisfied with flexible wrists. A person’s needs, work and prosthesis skills should be taken into account when prescribing a prosthesis wrist.Trial registrationNederlands Trial Register NTR3984.
