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.

Reflex sympathetic dystrophy of the upper extremity - a 5.5-year follow-up - Part I. Impairments and perceived disability

The aim of this retrospective and long-term follow-up study was to identify impairments resulting from reflex sympathetic dystrophy (RSD) of the upper extremity and to analyze the relationship between impairment and disability in RSD patients. The study group consisted of a referred sample of 65 RSD patients, with clinical signs in the upper extremity. RSD developed after fractures of the wrist or hand in 29 patients or after a carpal tunnel release in 9 patients. The mean interval between the RSD diagnosis and our evaluation was 5.5 (3-9) years (SD = 0.8). The main outcome measurements were the impairments assessed by standard physical examination. ADL and pain were quantified with a visual analogue scale (VAS). Pain was evaluated immediately before and after the physical examination and the perceived pain was determined in the week before the examination. Significant differences in impairments were found between the affected and the unaffected sides (p < 0.05). According to the AMA-guides, the impairments did not lead to disabilities. Significant correlations were found between VAS-ADL and VAS-pain in the last week prior to evaluation and full fist grip-strength. Pain seems to be the most disabling effect.

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.

Measurement of severity of sports injuries: an epidemiological study

Objective: To evaluate the severity of sports injuries in relation to the severity of injuries due to other causes and in relation to type of sport, using generally applied measures of injury severity. Subjects: A total of 12 403 patients, 4–50 years old, who were treated in the trauma department of the Groningen University Hospital for a sports injury, from January 1990 until January 1997. Method: All patients treated because of an injury entered the study. A distinction was made between injuries caused by playing sports, home and leisure accidents, traffic accidents and violence. The severity of the injuries was assessed by using the criteria of rate of admission, Injury Severity Scale (ISS). Finally the sports injuries were analysed with regard to type of sport. Results: In total, 57 760 injuries were registered. After injuries due to home and leisure accidents (44%; 25 228) sports injuries (21%; 12 403) were the most frequent cause of injury. Of the patients with a sports injury, 7.9% (980) were admitted, which is more than with home and leisure accidents (6.7%; 1690) but less than with traffic accidents (21.5%; 2202) and violence (9.3%; 364). In a majority of cases, admission was related to a limited number of types of sport. The mean ISS of sports injuries was low, as with injuries following home and leisure accidents and violence. The percentage of sports injuries with an ISS higher than or equal to 16 and the percentage mortality were both low in comparison to injuries due to violence or traffic accidents. Conclusions: Sports injuries rank second highest in terms of cause of injury, after home and leisure accidents; and rank third in terms of severity, after traffic accidents and violence. Even though the ISS is low, sports injuries may have serious consequences.

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.

Burst fractures of the thoracolumbar spine: changes of the spinal canal during operative treatment and follow-up

Abstract. Although multiple studies have concluded operative decompression of a traumatically narrowed spinal canal is not indicated because of spontaneous remodeling, instrumental decompression is frequently used as part of the operative treatment of spinal fractures. To investigate the process of remodeling, we studied the diameter of the spinal canal in 95 patients with burst fractures at the thoracolumbar junction (T9-L2). To measure and compare the spinal canals diameter we used either computed tomography (CT) scans or radiographs, made preoperatively, postoperatively, after 9 months and after 24 months. In lateral plain radiographs we found that the initial percentage of cases with bony canal narrowing preoperatively of 76.5 was reduced to 18.4% postoperatively, to 8.2% at 9 months, and to 2.4% at 24 months. In CT scans in a selection of patients, the mean residual diameter of the spinal canal was 53% preoperatively and 78% at 24 months. The posterior segmental height increases during operation and decreases in the respective periods after operation. So ligamentotaxis can only play a role in the perioperative period. We conclude that a significant spontaneous remodeling of the spinal canal follows the initial surgical reduction. Two years after operation, bony narrowing of the spinal canal is only recognizable in 2.4% of the patients on plain lateral radiographs. The remodeling of the spinal canal can be seen on plain radiographs, although not as accurately as on CT scans.

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.

The incidence of non-union following unreamed intramedullary nailing of femoral shaft fractures

INTRODUCTION Stabilisation of fractures with an intramedullary nail is a widespread technique in the treatment of femoral shaft fractures in adults. To ream or not to ream is still debated. The primary objective of this study was to determine the incidence of non-union following unreamed intramedullary stabilisation of femoral fractures. Secondary objectives were intra- and postoperative complications and implant failure. METHODS Between March 1995 and June 2005, 125 patients with 129 traumatic femoral shaft fractures were treated with as unreamed femoral nail. From this retrospective single centre study, 18 patients were excluded due to insufficient follow up data, including 1 patient who died within 2 days after severe head injury. Sixty-six patients had suffered multiple injuries. 21 fractures were open. According to the AO classification, there were 54 type A, 42 type B, and 14 type C fractures. Dynamic proximal locking was performed in 44 cases (36 type A and 8 type B fractures). RESULTS Non-union occurred in two patients (1.9%; one type B and one type C fractures). Intra-operative complications were seen in three patients (2.8%). Postoperative in-hospital complications occurred in 29 patients (27%). Local superficial infection occurred in two patients (1.9%), there were no cases of deep infection. Implant failure occurred in three patients (2.8%): nail breakage was seen in two patients. CONCLUSION In this study, the incidence of non-union following unreamed intramedullary nailing is low (1.9%) and comparable with the best results of reamed nailing in the literature.
