ABSTRACT

BACKGROUND: There is no well-established gold standard for treating trochanteric femur fractures in the elderly. The two common treatment options are cephalomedullary nails (CMN) and sliding hip screws (SHS). In this study, treatment using CMN and SHS were compared for a cohort of patients older than 70 years of age: The main outcomes were quality of life and main residence after surgery. METHODS: In this retrospective study we analyzed 24,919 patients from 100 hospitals, treated between 2016 and 2019 and documented in the Registry for Geriatric Trauma. The impact of CMN vs. SHS on the walking ability, quality of life (QoL), living situation, mortality, and revision rate were analyzed. To analyze the change of the living situation, the main residence 120 days after surgery for patients, who lived in their own home before fracture, was described for both groups. FINDINGS: A total of 10,995 patients could be included of which 10,436 patients were treated with CMN and 369 patients with SHS. 120 days postoperative the QoL differed significantly (p = 0.020) in favor of treatment using CMN. 26% of the SHS group who lived at home prior to surgery had to reside in a nursing home after surgery, whereas the rate was only 18% in the CMN group (p < 0.001). No significant difference in the mortality rate nor a difference in the walking ability 120 days postoperative were found. CMN were implanted more promptly (median: 13.9 vs. 18.4 hours; p < 0,001). No differences were found concerning the revision rate between the two groups, neither during inpatient treatment (p = 0.723) nor during the 120 day follow-up period (p = 0.524). INTERPRETATION: There might be a benefit for geriatric patients with trochanteric femur fractures to be treated with a proximal femur nail in regard to a higher QoL and a reduced institutionalization rate. Mortality or revision rate was not affected by the chosen implant.

ABSTRACT

BACKGROUND AND OBJECTIVE: Malnutrition in geriatric trauma patients is associated with an increased risk of complications and mortality and is therefore a key risk factor. The assessment of the affected patients plays an important role in improving the outcome of this growing patient group. MATERIAL AND METHODS: In 2016 a questionnaire was sent to 571 departments specialized in traumatology and orthopedics throughout Germany. The following were recorded: level of care, expertise in geriatric trauma, nutrition-based screening procedures and nutritional ward round procedures. RESULTS: The response rate was 57% (n = 325) and closely reflected the treatment reality in Germany with respect to the level of care (superregional, regional or local trauma center and those without special qualifications). In 14% (n = 45) the participants were German Society for Trauma Surgery(DGU)-certified centers for age-related traumatology, while a further 5% (n = 15) were in the process of certification. The nutritional status was assessed in 56% (n = 181) of the clinics. Most frequently used was the body mass index (74%) followed by the mini nutritional assessment (30%), laboratory parameters (29%) and nutritional risk screening 2002 (19%). Some additional methods were specified. In approximately half of the departments nutritional ward rounds took place in regular wards (50%) and intensive care units (57%). DISCUSSION: The high response rate of this study seems to show the particular interest for malnutrition in geriatric trauma patients. This is reflected in an increase in the participating clinics compared to past surveys and also the more regularly performed assessment of nutritional status and implementation of nutritional visits. CONCLUSION: The establishment of suitable and time-effective screening instruments and their implementation are still a challenge.

ABSTRACT

INTRODUCTION: Arthroplasty of the hip and knee is 1 of the 20 most frequent operations in Germany. Periprosthetic fracture is one of the most feared complications following primary or revision arthroplasty. Present publication aims to analyse differences between patients with periprosthetic fracture around total knee arthroplasty (PFTKA) and patients with periprosthetic fracture around total hip arthroplasty (PFTHA) concerning demographics, clinical course, complications and return to pre-fracture mobility. METHODS: Prospective single-centre observation study of periprosthetic femoral fractures with stable implants. Present subgroup analysis includes patients with PFTKA and PFTHA. All patients were treated with polyaxial angular stable plates using two standardized techniques: a minimally invasive percutaneous distal insertion technique and a mini-open technique. Data collection included implant- and operation-related information as well as demographics, clinical course, complications and return to pre-fracture mobility. Data were collected during a 12-month follow-up. RESULTS: We were able to analyse the data of 73 patients. The PFTKA group had 37 patients with a mean age of 76 ±â€¯10 years; 88% were female. After 1 year, 3 patients in this cohort had died; 68% of survivors had reached their pre-fracture mobility; 22% had undergone operative revisions for various reasons. The PFTHA cohort included 36 patients with a mean age of 80 ±â€¯13 years, 72% were female. After 1 year, 9 patients had died in this cohort, 42% of survivors had reached their pre-fracture mobility. Non-operative complications occurred for 16% in the PFTKA group and 64% in the PFTHA group (p < 0.001). 11% had undergone operative revisions for various reasons, among them, two cases of nonunion but no primary infection. CONCLUSION: On average, compared to the PFTHA patients, PFTKA patients were younger, underwent significantly lower rates of non-operative complications, had a tendency towards lower mortality, and returned to pre-fracture mobility at higher rates, although they tended to have more revisions when compared to treatment for PFTHA. Overall, when periprosthetic fractures of the femur were treated using polyaxial locking plate osteosynthesis, patients showed very low rates of nonunion and no primary infection.

ABSTRACT

BACKGROUND: Previous studies revealed evidence that induced hypothermia attenuates ischemic organ injuries after severe trauma. In the present study, the effect of hypothermia on liver damage was investigated in a porcine long term model of multi-system injury, consisting of blunt chest trauma, penetrating abdominal trauma, musculoskeletal injury, and hemorrhagic shockMETHODS: In 30 pigs, a standardized polytrauma including blunt chest trauma, penetrating abdominal trauma, musculoskeletal injury, and hemorrhagic shock of 45% of total blood volume was induced. Following trauma, hypothermia of 33∘C was induced for 12 h and intensive care treatment was evaluated for 48 h. As outcome parameters, we assessed liver function and serum transaminase levels as well as a histopathological analysis of tissue samples. A further 10 animals served as controls. RESULTS: Serum transaminase levels were increased at the end of the observation period following hypothermia without reaching statistical significance compared to normothermic groups. Liver function was preserved (p⩽ 0.05) after the rewarming period in hypothermic animals but showed no difference at the end of the observation period. In H&E staining, cell death was slightly increased hypothermic animals and caspase-3 staining displayed tendency towards more apoptosis in hypothermic group as well. CONCLUSIONS: Induction of hypothermia could not significantly improve hepatic damage during the first 48 h following major trauma. Further studies focusing on multi-organ failure including a longer observation period are required to illuminate the impact of hypothermia on hepatic function in multiple trauma patients.

ABSTRACT

BACKGROUND: Geriatric traumatology is increasing in importance due to the demographic transition. In cases of fractures close to large joints it is questionable whether primary joint replacement is advantageous compared to joint-preserving internal fixation. OBJECTIVE: The aim of this study was to describe the importance of prosthetic joint replacement in the treatment of geriatric patients suffering from frequent periarticular fractures in comparison to osteosynthetic joint reconstruction and conservative methods. MATERIAL AND METHODS: A selective search of the literature was carried out to identify studies and recommendations concerned with primary arthroplasty of fractures in the region of the various joints (hip, shoulder, elbow and knee). RESULTS: The importance of primary arthroplasty in geriatric traumatology differs greatly between the various joints. Implantation of a prosthesis has now become the gold standard for displaced fractures of the femoral neck. In addition, reverse shoulder arthroplasty has become an established alternative option to osteosynthesis in the treatment of complex proximal humeral fractures. Due to a lack of large studies definitive recommendations cannot yet be given for fractures around the elbow and the knee. Nowadays, joint replacement for these fractures is recommended only if reconstruction of the joint surface is not possible. CONCLUSION: The importance of primary joint replacement for geriatric fractures will probably increase in the future. Further studies with larger patient numbers must be conducted to achieve more confidence in decision making between joint replacement and internal fixation especially for shoulder, elbow and knee joints.

ABSTRACT

The aim of the present study was to identify patient factors associated with higher costs in hip fracture patients. The mean costs of a prospectively observed sample of 402 patients were 8853 €. The ASA score, Charlson comorbidity index, and fracture location were associated with increased costs. PURPOSE: Fractures of the proximal end of the femur (hip fractures) are of increasing incidence due to demographic changes. Relevant co-morbidities often present in these patients cause high complication rates and prolonged hospital stays, thus leading to high costs of acute care. The aim of this study was to perform a precise cost analysis of the actual hospital costs of hip fractures and to identify patient factors associated with increased costs. METHODS: The basis of this analysis was a prospectively observed single-center trial, which included 402 patients with fractures of the proximal end of the femur. All potential cost factors were recorded as accurately as possible for each of the 402 patients individually, and statistical analysis was performed to identify associations between pre-existing patient factors and acute care costs. RESULTS: The mean total acute care costs per patient were 8853 ± 5676 € with ward costs (5828 ± 4294 €) and costs for surgical treatment (1972 ± 956 €) representing the major cost factors. The ASA score, Charlson comorbidity index, and fracture location were identified as influencing the costs of acute care for hip fracture treatment. CONCLUSION: Hip fractures are associated with high acute care costs. This study underlines the necessity of sophisticated risk-adjusted payment models based on specific patient factors. Economic aspects should be an integral part of future hip fracture research due to limited health care resources.

ABSTRACT

BACKGROUND: Most studies focusing on improving the nutritional status of geriatric trauma patients exclude patients with cognitive impairment. These patients are especially at risk of malnutrition at admission and of worsening during the perioperative fasting period. This study was planned as a feasibility study to identify the difficulties involved in including this high-risk collective of cognitively impaired geriatric trauma patients. PATIENTS AND METHODS: This prospective intervention study included cognitively impaired geriatric patients (Mini-Mental State Examination <25, age >65 years) with hip-related fractures. We assessed Mini Nutritional Assessment (MNA), Nutritional Risk Screening (NRS 2002), body mass index, calf circumference, American Society of Anesthesiologists' classification, and Braden Scale. All patients received parenteral nutritional supplementation of 800 kcal/d for the 96-hour perioperative period. Serum albumin and pseudocholinesterase were monitored. Information related to the study design and any complications in the clinical course were documented. RESULTS: A total of 96 patients were screened, among whom eleven women (median age: 87 years; age range: 74-91 years) and nine men (median age: 82 years; age range: 73-89 years) were included. The Mini-Mental State Examination score was 9.5 (0-24). All patients were manifestly undernourished or at risk according to MNA and NRS 2002. The body mass index was 23 kg/m2 (13-30 kg/m2), the calf circumference was 29.5 cm (18-34 cm), and the mean American Society of Anesthesiologists' classification status was 3 (2-4). Braden Scale showed 18 patients at high risk of developing pressure ulcers. In all, 12 patients had nonsurgical complications with 10% mortality. Albumin as well as pseudocholinesterase dropped significantly from admission to discharge. The study design proved to be feasible. CONCLUSION: The testing of MNA and NRS 2002 was feasible. Cognitively impaired trauma patients proved to be especially at risk of malnutrition. Since 96 hours of parenteral nutrition as a crisis intervention was insufficient, additional supplementation could be considered. Laboratory and functional outcome parameters for measuring successive supplementation certainly need further evaluations involving randomized controlled trials.

ABSTRACT

PURPOSE: The most commonly used mobility assessments for screening risk of falls among older adults are rating scales such as the Tinetti performance oriented mobility assessment (POMA). However, its correlation with falls is not always predictable and disadvantages of the scale include difficulty to assess many of the items on a 3-point scale and poor specificity. The purpose of this study was to describe the ability of the new Aachen Mobility and Balance Index (AMBI) to discriminate between subjects with a fall history and subjects without such events in comparison to the Tinetti POMA Scale. METHODS: For this prospective cohort study, 24 participants in the study group and 10 in the control group were selected from a population of patients in our hospital who had met the stringent inclusion criteria. Both groups completed the Tinetti POMA Scale (gait and balance component) and the AMBI (tandem stance, tandem walk, ten-meter-walk-test, sit-to-stand with five repetitions, 360° turns, timed-up-and-go-test and measurement of the dominant hand grip strength). A history of falls and hospitalization in the past year were evaluated retrospectively. The relationships among the mobility tests were examined with Bland-Altmananalysis. Receiver-operated characteristics curves, sensitivity and specificity were calculated. RESULTS: The study showed a strong negative correlation between the AMBI (17 points max., highest fall risk) and Tinetti POMA Scale (28 points max., lowest fall risk; r = -0.78, p < 0.001) with an excellent discrimination between community-dwelling older people and a younger control group. However, there were no differences in any of the mobility and balance measurements between participants with and without a fall history with equal characteristics in test comparison (AMBI vs. Tinetti POMA Scale: AUC 0.570 vs. 0.598; p = 0.762). The Tinetti POMA Scale (cut-off <20 points) showed a sensitivity of 0.45 and a specificity of 0.69, the AMBI a sensitivity of 0.64 and a specificity of 0.46 (cut-off >5 points). CONCLUSION: The AMBI comprises mobility and balance tasks with increasing difficulty as well as a measurement of the dominant hand-grip strength. Its ability to identify fallers was comparable to the Tinetti POMA Scale. However, both measurement sets showed shortcomings in discrimination between fallers and non-fallers based on a self-reported retrospective falls-status.

ABSTRACT

PURPOSE: Prevalence of malnutrition in geriatric trauma patients ranges between 30 and 50 % in Germany. Malnutrition is associated with impaired wound healing, a prolonged in-hospital stay, reduced post-traumatic mobility, as well as a higher mortality. Thus, detection and improvement of nutritional status could be a fundamental contribution in optimizing the treatment of these patients. METHODS: We sent a web-based questionnaire to 579 German hospitals with traumatological expertise, seeking information on the institutional care level, number of beds, use of nutritional assessments, and use of defined laboratory parameters for the detection of malnutrition. Furthermore, we focused on the presence and frequency of nutrition ward rounds on the intensive care unit. RESULTS: We received 151 answers. Nutritional status was analysed in one-third (N = 50). The half of these 50 clinics (54 %, N = 27) were using the body mass index (BMI), 20 % (N = 10) were using the nutritional risk screening (NRS), and 14 % (N = 7) used the mini nutritional assessment. 38 hospitals indicated a regular nutrition ward round; 63 % of them occurred daily, 13 % had a weekly frequency, and 24 % were on demand. Laboratory parameters were used inhomogeneously. Except for the more frequent use of the NRS (p = 0.026) in local trauma centres, we found no significant difference in the detection of malnutrition according to the care level. CONCLUSIONS: Although we know malnutrition is a frequent condition in geriatric patients, a minority of clinics considered it. The BMI and the NRS showed acceptance in practice; other parameters were used inhomogeneously. Although these findings may be limited in their significance, they indicate that the detection of malnutrition needs further investigation.

ABSTRACT

BACKGROUND: Hypothermia has been discussed as playing a role in improving the early phase of systemic inflammation. However, information on the impact of hypothermia on the local inflammatory response is sparse. We therefore investigated the kinetics of local and systemic inflammation in the late posttraumatic phase after induction of hypothermia in an established porcine long-term model of combined trauma. MATERIALS & METHODS: Male pigs (35 ± 5kg) were mechanically ventilated and monitored over the study period of 48 h. Combined trauma included tibia fracture, lung contusion, liver laceration and pressure-controlled hemorrhagic shock (MAP < 30 ± 5 mmHg for 90 min). After resuscitation, hypothermia (33°C) was induced for a period of 12 h (HT-T group) with subsequent re-warming over a period of 10 h. The NT-T group was kept normothermic. Systemic and local (fracture hematoma) cytokine levels (IL-6, -8, -10) and alarmins (HMGB1, HSP70) were measured via ELISA. RESULTS: Severe signs of shock as well as systemic and local increases of pro-inflammatory mediators were observed in both trauma groups. In general the local increase of pro- and anti-inflammatory mediator levels was significantly higher and prolonged compared to systemic concentrations. Induction of hypothermia resulted in a significantly prolonged elevation of both systemic and local HMGB1 levels at 48 h compared to the NT-T group. Correspondingly, local IL-6 levels demonstrated a significantly prolonged increase in the HT-T group at 48 h. CONCLUSION: A prolonged inflammatory response might reduce the well-described protective effects on organ and immune function observed in the early phase after hypothermia induction. Furthermore, local immune response also seems to be affected. Future studies should aim to investigate the use of therapeutic hypothermia at different degrees and duration of application.

ABSTRACT

PURPOSE: Traumatic insults result in an altered inflammatory response, in which alarmins release has a central role. The impact of haemorrhagic shock intensity on the long-term kinetics of alarmins is not yet fully elucidated. We investigated these aspects in a combined trauma (chest, abdominal, and extremities injury) porcine model with different severities and durations of haemorrhagic shock. METHODS: After induction of combined trauma (tibia fracture, lung contusion, and liver laceration), haemorrhagic shock was induced at different intensities: moderate haemorrhage (MH; n = 15): mean arterial pressure (MAP) <30 ± 5 mmHg [maximum loss of total blood volume (TBVmax): 45 %] for 90 min, and severe haemorrhage (SH; n = 10): MAP <25 ± 5 mmHg (TBVmax 50 %) for 120 min. Resuscitation was performed using a standardized crystalloid infusion protocol. Animals were mechanically ventilated and underwent ICU-monitoring for 48 h (MH) and 48.5 h (SH). Blood samples were collected over the clinical time course, and systemic levels of serum alarmins [High-Mobility Group Protein B-1 (HMGB-1) and Heat Shock Protein 70 (HSP70)] were measured using an ELISA kit. RESULTS: Heart rate, systemic blood pressure, lactate, and base excess were significantly altered as a function of haemorrhagic shock in both trauma groups (MH and SH). Systemic HMGB-1 levels were significantly elevated in both trauma groups when compared to the sham group. Haemorrhagic shock severity and duration were positively correlated with HMGB-1 levels and compared to baseline values, concentrations remained significantly increased in SH when compared to MH. On the other hand, we observed a significant decrease in the systemic HSP70 levels of trauma groups (MH, and SH) when compared to the sham group, which was significantly decreased compared to baseline values in SH over the entire time course. CONCLUSION: Our data show that haemorrhagic shock duration and severity affect the systemic levels of HMGB-1 and HSP70. This early alarmins release after trauma can be used to guide the treatment strategies (e.g. surgical procedures) of polytrauma patients.

ABSTRACT

BACKGROUND: An animal polytrauma model was developed, including trunk and extremity injuries combined with hemorrhagic shock and a prolonged post-traumatic phase. This could be useful for the assessment of different therapeutic approaches during intensive care therapy. METHODS: A standardized polytrauma including lung contusion, liver laceration and lower leg fracture was applied in 25 pigs. They underwent controlled haemorrhage either with a blood volume loss of 45 % and a median arterial pressure (MAP) <30 mmHg/90 min (group L, n = 15) or a 50 % blood loss of and an MAP <25 mmHg/120 min (group H, n = 10). Five non-traumatized pigs served as a control (group C). Subsequently, intensive care treatment was given for an observational period of 48 h. RESULTS: Both trauma groups showed signs of shock and organ injury (heart rate, MAP and lactate). The frequency of cardiopulmonary resuscitation (CPR) and lung injury was directly related to the severity of the haemorrhagic shock (CPR-group L: 4 of 15 pigs, group H: 4 of 10 pigs; Respiratory failure-group L: 3 of 13, group H: 3 of 9. There was no difference in mortality between trauma groups. CONCLUSION: The present data suggest that our model reflects the mortality and organ failure of polytrauma in humans during shock and the intensive care period. This suggests that the experimental protocol could be useful for the assessment of therapeutic approaches during the post-traumatic period.

ABSTRACT

Background. Previous studies showed significant interaction between the local and systemic inflammatory response after severe trauma in small animal models. The purpose of this study was to establish a new combined trauma model in pigs to investigate fracture-associated local inflammation and gain information about the early inflammatory stages after polytrauma. Material and Methods. Combined trauma consisted of tibial fracture, lung contusion, liver laceration, and controlled hemorrhage. Animals were mechanically ventilated and under ICU-monitoring for 48 h. Blood and fracture hematoma samples were collected during the time course of the study. Local and systemic levels of serum cytokines and diverse alarmins were measured by ELISA kit. Results. A statistical significant difference in the systemic serum values of IL-6 and HMGB1 was observed when compared to the sham. Moreover, there was a statistical significant difference in the serum values of the fracture hematoma of IL-6, IL-8, IL-10, and HMGB1 when compared to the systemic inflammatory response. However a decrease of local proinflammatory concentrations was observed while anti-inflammatory mediators increased. Conclusion. Our data showed a time-dependent activation of the local and systemic inflammatory response. Indeed it is the first study focusing on the local and systemic inflammatory response to multiple-trauma in a large animal model.

ABSTRACT

BACKGROUND: Proximal femoral fractures are common in the elderly. Surgical and postoperative complications are of major importance in this population. Numerous factors affecting the treatment results could be identified so far. The effect of surgeons' experience in terms of educational status is not entirely clarified yet. The aim of the present study was to analyse the effect of surgeons' educational status on the outcome in proximal femoral fractures. Therefore treatment results were compared in terms of individual surgeons' experience. Furthermore, the surgical education concept of our department was evaluated. MATERIAL AND METHODS: At a national trauma centre, patients of at least 60 years of age with proximal femoral fractures were prospectively screened. Patient-specific parameters like Barthel index, ASA score, Charlson score, patients' age and type of fracture were collected at the time of hospital admission. During the in-hospital stay type of fracture treatment, surgery time, number of blood transfusions, perioperative complications, duration of in-hospital stay as well as in-hospital mortality were recorded. Results were analysed for osteosynthesis and prosthesis depending on the surgeons' educational status. Four different groups of surgeons were distinguished (inexperienced senior house officer; experienced senior house officer; specialist in orthopaedics and accident surgery; specialist in orthopaedics and accident surgery with an additional qualification for special accident surgery). RESULTS: 402 patients with coxal femoral fractures could be included into the study. 160 patients (40 %) sustained complications of different severity. In-hospital mortality was shown to be 6.2 %. Separate consideration of osteosynthesis and prosthesis revealed no difference between the four groups of surgeons regarding mortality rate, number of blood transfusions and in-hospital stay. In terms of cutting/suture time consultants with a further specialisation in trauma surgery were significantly faster. CONCLUSION: Apart from cutting/suture time, surgeons' educational status had no statistically significant impact on the rate of complications, rate of blood transfusions, hospital mortality and in-hospital stay. It can be presumed that surgical education according to our educational concept has no negative effects on treatment quality of patients with proximal femoral fractures. Differences in cutting/suture time give a hint for the additional expense that is connected with surgical education.

ABSTRACT

The number of agile patients in the 10th decade with a strong need for postoperative mobility will increase in the following decades. The present prospective study sought to prove if very old patients with hip-related fractures are disadvantaged according to incidence of complications, length of ICU and in-hospital stay, and in-hospital mortality. We included 402 patients, age 60 years and older, with hip related fractures. Operative treatment consisted of osteosynthesis or endoprothesis. ASA score, body mass index, Charlson Comorbidity Index, Barthel Index and Mini-Mental-Status were documented. We noted length of in-hospital stay and ICU stay as well as readmission to ICU and complications, including their dispersal according to Clavien-Dindo Classification. After univariate analysis, a multivariate analysis was performed. The examined cohorts were 85 patients aged 60-74 years, 253 75-90 years old and 64 >90 year old patients. In-hospital periods (13-14 days) mean stay on ICU (2 days) and frequency of readmission on ICU did not significantly differ statistically. Most complications were grade II, with comparable frequency and modality, displaying no significant difference throughout age-related groups (p=0.461). In-hospital mortality showing significance (p=0.014) only between 75-89 (4.4%) and >90-year-old (12.5%) cohort. Nevertheless, according to multivariate analysis, including the common risk factors, increased age was not an independent risk factor for dying (p=0.132). Patients at an advanced age with hip-related fractures showed neither a prolonged in-hospital nor ICU stay. There was no significant relation of advanced age to number and type of complications.
