[Minimally invasive treatment of serial metatarsal fractures by antegrade intramedullary K‑wire osteosynthesis]

Serial fractures of metatarsal bones are rare and usually caused by direct or indirect high-energy trauma; however, in cases of pre-existing diseases, such as diabetes mellitus, they also can occur spontaneously or as insidious fractures. Due to the substantial soft tissue swelling mostly associated with such injuries, minimally invasive osteosynthesis with intramedullary Kirschner-wires (K‑wires) is recommended. The antegrade technique for placement of the K‑wires is preferred as the technically simpler retrograde procedure has several significant disadvantages. The preferred operative approach is described in detail exemplified by two clinical cases.

Eradication of Acinetobacter baumannii/Enterobacter cloacae complex in an open proximal tibial fracture and closed drop foot correction with a multidisciplinary approach using the Taylor Spatial Frame®: a case report

Background

Multi-drug-resistant bacteria (e.g. Carbapenem-resistant Acinetobacter baumannii, extended-spectrum betalactamase or carbapenemase-producing enterobacteriaceae) are emerging in early-onset infections. So far, there is no report describing the eradication of these bacteria in a osseous infection of an open proximal tibial fracture in combination with the hexapod technology to address both osseous consolidation and closed drop foot correction.

Case presentation

After sustaining a proximal tibial fracture (Gustilo 3B), a 41-year-old man was primarily treated with open reduction and internal fixation by a locking plate and split-thickness skin graft in the home country. At the time of admission to our hospital there was a significant anterolateral soft tissue defect covered with an already-necrotic split-thickness graft and suspicious secretion. CAT and MRI scans revealed no signs of osseous healing, intramedullary distinctive osteomyelitis, as well as a large abscess zone in the dorsal compartment. Multiple wound smears showed multi-drug-resistant bacteria: Acinetobacter baumannii (Carbapenem resistant) as well as Enterobacter cloacae complex (AmpC overexpression). After implant removal, excessive osseous and intramedullary debridements using the Reamer Irrigator Aspirator (RIA^®) as well as initial negative pressure wound therapy were performed. Colistin hand-modelled chains and sticks were applied topically as well as an adjusted systemic antibiotic scheme was applied. After repetitive surgical interventions, the smears showed bacterial eradication and the patient underwent soft tissue reconstruction with a free vascularized latissimus dorsi muscle flap. External fixation was converted to a hexapod fixator (TSF^®) to correct primary varus displacement, axial assignment and secure osseous healing. A second ring was mounted to address the fixed drop foot in a closed fashion without further intervention. At final follow-up, 12 months after trauma, the patient showed good functional recovery with osseous healing, intact soft tissue with satisfactory cosmetics and no signs of reinfection.

Conclusions

A multidisciplinary approach with orthopaedic surgeons for debridement, planning and establishing osseous and joint correction and consolidation, plastic surgeons for microvascular muscle flaps for soft tissue defect coverage as well as clinical microbiologists for the optimized anti-infective treatment is essential in these challenging rare cases.

Outcome after surgical treatment of fragility ankle fractures in a certified orthogeriatric trauma center

INTRODUCTION

Orthogeriatric ankle fractures seem to play an essential role in terms of quality of life in the elderly. Knowledge of the outcome after orthogeriatric ankle fractures is sparse. The present study investigates the outcome after surgically treated ankle fractures at a certified orthogeriatric trauma center.

MATERIAL & METHODS

A retrospective observational study was performed investigating the outcome of surgically treated ankle fractures in orthogeriatric patients between 2015-2017. Outcome parameters included but were not limited to the EQ-5D 3 L, Barthel Index, Karlsson Score and the Charlson Comorbidity Index. Housing situation and mobility were evaluated and potential associations to the fracture pattern and the related treatment strategy were investigated.

RESULTS

In total, 58 patients were included (age 77.7 ± 6,2 years). The majority were AO-44 B2 fractures (72%). General outcome was related to the Parker score; a Parker Score of 9 prior surgery was independently associated with an improved outcome according to the EQ-5D 3 L and Barthel Index. Patients under 80 years of age also had better results. Place of residence did not significantly change after surgery. Neither different types of implants nor initial use of an external fixator (e.g. open fractures) did influence outcome. A wound healing impairment was found in 10% of our patients whereas the overall unplanned reoperation rate was 7%. Overall complication rate was 20%, one-year mortality was 10%.

CONCLUSIONS

Surgically treated ankle fractures in the elderly which are treated in a certified geriatric fracture center seem to have limited negative effect on their quality of life. We did not observe the otherwise often demonstrated high mortality rates, but still nearly half of the patients demonstrated perioperative complications, which emphasizes the need for optimal perioperative care at an orthogeriatric trauma center. Since there was a reasonable number of patients with wound healing issues this study supports the idea of a staged protocol using external fixation with secondary ORIF.

[Peri-implant femoral fracture following hip arthrodesis in adolescence]

This article presents the case of an 83-year-old woman with a peri-implant femoral fracture after hip arthrodesis in adolescence. Due to the rarity of such operations, there is no standardized approach for these cases. In order to secure the treatment goal of rapid pain-adapted full weight bearing despite reduced bone quality, it was decided to perform a new osteosynthesis with a retrograde femoral nail after removal of some fixation screws of the existing arthrodesis plate. Due to this type of treatment, the preservation of activity and independence of an older trauma patient could be sustainably secured despite operative challenges. Taking an extended osteoporosis treatment into consideration, a bony fracture consolidation and complete convalescence of activity and autonomy were ultimately achieved.

[Fractures of the anterior process of the calcaneus-frequently overlooked injuries following ankle sprains]

Fractures to the anterior process of the calcaneus (PAC) have long been considered rare injuries and have received little attention in clinical research. On the contrary, recent studies have reported a distinct higher incidence, especially following ankle sprains. Decisive reasons are that fractures of the PAC are regularly missed on plain radiographs and that a clinical differentiation from injuries to the lateral ankle ligaments is difficult. With the broad availability of cross-sectional imaging modalities fractures of the PAC are diagnosed more frequently and more reliably. The purpose of this review is to give an overview on the diagnostics, classification and treatment recommendations to this topic and discuss the studies available. To date no evidence-based recommendations are available for the treatment of fractures of the PAC. The few case reports and case series published, predominantly recommend conservative treatment; however, the treatment regimens vary considerably, ranging from immobilization in a lower leg cast (2-10 weeks) to early functional treatment with full weight-bearing. The surgical treatment by open reduction and internal fixation has been described primarily for large dislocated fractures. Surgical excision is considered mainly in cases of persistent pain or symptomatic non-union following non-operative treatment. For both, non-operative and operative treatment, the case reports and case series report satisfactory outcomes for the majority of patients. Nevertheless, comparative studies and patient-rated outcome measures are missing. Therefore, evidence-based recommendations cannot be given.

[Augmentation techniques on the proximal femur]

BACKGROUND

Due to the demographic change fractures of the proximal femur are an increasing major healthcare problem and are associated with the highest mortality among frailty fractures.

OBJECTIVES

These mainly osteoporosis-associated fractures of the hip often represent a surgical challenge and the outcome has a decisive influence on the preservation of function and independency of orthogeriatric patients. Augmentation techniques could improve the stability of osteosynthesis in proximal femoral fractures.

METHODS

Cement augmentation of proximal femoral nailing (PFNA) for the treatment of pertrochanteric femoral fractures is the most commonly used and standardized method of augmentation for these fractures by which a safer condition for immediate full weight bearing and mobilization can be achieved.

RESULTS

In biomechanical and clinical studies good fracture healing was shown and there was no evidence of cement-associated complications in augmented PFNA nailing. In the majority of patients the mobility level prior to trauma could be achieved.

CONCLUSION

In addition to the optimal surgical treatment, secondary prevention such as osteoporosis management to avoid further fractures is crucial in the treatment of these patients. This article is based on the current literature and provides an overview of the possible applications of cement augmentation for the treatment of proximal femoral fractures. In addition the surgical approach as well as previous scientific data on an established osteosynthesis using cement-augmented PFNA for the treatment of pertrochanteric frailty fractures are presented.

[Interdisciplinary management in geriatric trauma surgery : Results of a survey in Austria]

BACKGROUND

The treatment of geriatric patients in the field of trauma surgery is increasingly gaining importance. To provide optimized treatment to these mostly multimorbid patients, interdisciplinary treatment concepts between trauma surgeons and geriatricians have been designed and implemented successfully.

OBJECTIVES

The aim of this survey was to evaluate the current state of interdisciplinary management in the treatment of geriatric patients on trauma surgery wards throughout Austria.

MATERIAL AND METHODS

The directors of 64 Austrian trauma surgery wards were surveyed using an online-questionnaire regarding the current interdisciplinary treatment of geriatric patients.

RESULTS

A total of 39 (61 %) questionnaires were analyzed. Of the participating wards, 20 % distinguished between geriatric and non-geriatric patients. There were various criteria to classify the patients. The average percentage of patients older than 70 years was 43 %. Of the participating wards, 26 % had established a periodical cooperation between trauma surgeons and geriatricians and 8 % of the participants stated that there is no interdisciplinary cooperation. The establishment of an interdisciplinary treatment concept in the near future was planned in 28 %. The most commonly mentioned obstacle that prevented trauma surgery wards from establishing an interdisciplinary management model was the lack of personnel resources (59 %) - especially the lack of geriatricians (62 %).

CONCLUSION

The survey's results underline the geriatric trauma surgery's great importance especially regarding the high percentage of geriatric patients, as well as the fact that the significance of the interdisciplinary cooperation between trauma surgeons and geriatricians is not yet perceived by the majority of Austrian trauma surgery wards.

Value of a coordinated management of osteoporosis via Fracture Liaison Service for the treatment of orthogeriatric patients

INTRODUCTION

The prevalence of osteoporosis in female patients over 75 years of age is 59.2 %. In Germany ~6.3-7.8 million patients are affected by osteoporosis. In 77 % of german patients osteoporosis is not treated adequately. Even after fragility fractures only 16-21 % of female patients and 3 % of male patients are supplied with a specific osteoporosis therapy. Establishing a Fracture Liaison Services (FLS) is a possible addition to co-management for an efficient treatment of osteoporosis in orthogeriatric patients.

MATERIALS AND METHODS

According to a treatment algorithm adapted to the DVO guideline 2014, data of 251 (77 male, 173 female) patients were collected over 3 months. For the assessment specific and standardized questionnaires were used. There was also a basic laboratory testing for osteoporosis done.

RESULTS

The average age of female patients was 76.1 years, in male patients 76.6 years. Thirty-seven patients had vertebral fractures, 25 patients proximal humerus fractures, 18 distal radius fractures and a total of 78 proximal femur fractures were recorded. Eighteen percent of the 251 patients have already been treated with a basic and 11 % with a specific osteoporosis medication. Approximately 40 % of the orthogeriatric patients were diagnosed with osteoporosis for the first time in our clinic. Less than 1 % of the patients had a vitamin D level over 40 ng/ml and 32 % had a vitamin D level under 10 ng/ml. Sixty-five percent of the discharged patients received a basic osteoporosis therapy and 25 % an additional specific therapy.

DISCUSSION

Due to the demographic development osteoporosis-associated fractures steadily increase. In addition to the surgical treatment of fractures, osteological diagnosis and treatment are essential components of successful treatment and critical to the prevention of further fractures. A combination of orthogeriatric center and fracture liaison service allows a more efficient treatment of osteoporosis by close supervision of orthogeriatric patients by the physicians involved.

[Proximal femoral fractures in the elderly]

Proximal femoral fractures represent an increasing major healthcare problem due to the demographic changes in this aging population and are associated with the highest mortality among fractures in elderly patients after suffering insufficiency injuries (so-called fragility fractures). The main aim in the treatment of orthogeriatric patients who suffered from a proximal femoral fracture is the preservation of function and independency. Given the high prevalence of comorbidities in these patients, interdisciplinary and interprofessional approaches are required. The use of modern osteosynthesis procedures can provide an improved, individualized surgical treatment with early full weight bearing of the affected extremity. Another aspect is the accompanying geriatric treatment which is associated with a significant reduction of perioperative and postoperative complications. In addition to acute treatment, the organization of secondary fracture prevention is a crucial pillar of treatment. This article provides an overview of the essential elements of orthogeriatric trauma surgery in elderly patients following proximal femoral fractures.

Fragility non-hip fracture patients are at risk

INTRODUCTION

Fragility fractures are a growing worldwide health care problem. Hip fractures have been clearly associated with poor outcomes. Fragility fractures of other bones are common reasons for hospital admission and short-term disability, but specific long-term outcome studies of non-hip fragility fractures are rare. The aim of our trial was to evaluate the 1-year outcomes of non-hip fragility fracture patients.

METHODS

This study is a retrospective cohort review of 307 consecutive older inpatient non-hip fracture patients. Patient data for analysis included fracture location, comorbidity prevalence, pre-fracture functional status, osteoporosis treatments and sociodemographic characteristics. The main outcomes evaluated were 1-year mortality and post-fracture functional status.

RESULTS

As compared to the expected mortality, the observed 1-year mortality was increased in the study group (17.6 vs. 12.2 %, P = 0.005). After logistic regression, three variables remained as independent risk factors for 1-year mortality among non-hip fracture patients: malnutrition (OR 3.3, CI 1.5-7.1), Charlson comorbidity index (CCI) (OR 1.3, CI 1.1-1.5) and the Parker Mobility Score (PMS) (OR 0.85, CI 0.74-0.98). CCI and PMS were independent risk factors for a high grade of dependency after 1 year. Management of osteoporosis did not significantly improve after hospitalization due to a non-hip fragility fracture.

CONCLUSION

The outcomes of older non-hip fracture patients are comparable to the poor outcomes of older hip fracture patients, and appear to be primarily related to comorbidities, pre-fracture function and nutritional status. The low rate of patients on osteoporosis medications likely reflects the insufficient recognition of the importance of osteoporosis assessment and treatment in non-hip fracture patients. Increased clinical and academic attention to non-hip fracture patients is needed.

Urinary incontinence and poor functional status in fragility fracture patients: an underrecognized and underappreciated association

PURPOSE/INTRODUCTION

Urinary incontinence (UI) affects some 20 % of community-dwelling older people and 30-60 % of people in institutional care. UI is known as an independent predictor of falls, and likely impacts fracture rates. The aim of the study was to measure the prevalence of UI in a typical fragility fracture population, to evaluate the relationship of UI with functional disability in the post-acute setting.

METHODS

Our study is a retrospective cross-sectional study of patients admitted to rehabilitation setting after inpatient hospital management for a fragility fracture. We included all consecutively admitted fragility fracture patients aged over 65. All patients underwent standard clinical examination and Geriatric Assessment. We assessed UI using a two-stage process with a six-item UI screening questionnaire followed by an interview.

RESULTS

1,857 (80.7 % female) patients were available for analysis, mean age was 81.7 years. UI was identified in 59.2 % of all fragility fracture patients, and was more prevalent in females. Patients suffering from UI differed significantly in almost all measured functional and cognitive tests, with increased dependency/lower ADL scores, increased rates of immobility, and higher rates of cognitive dysfunction and depression.

CONCLUSION

This study confirms the high prevalence of UI in older fragility fracture patients, and the association between UI and functional impairments. The diagnostic work-up and treatment of patients should be focused on the special needs of these older patients. More efforts are needed to increase awareness about prevalence and consequences of UI among older fragility fracture patients.

Treatment of osteoporosis in older adults

Osteoporosis is characterized by low bone mineral density and associated with low impact skeletal fractures most often involving the spine, hip, pelvis, proximal humerus and forearm. It is predominantly a disease of ageing, affecting primarily postmenopausal women, but also older men. Both hip and non-hip fractures are associated with excess mortality post-fracture. Fragility fractures can be acutely and subacutely life threatening for many older patients. Postmenopausal osteoporosis has a big impact on health care expenses, with associated spending expected to double for osteoporosis by the year 2050. Despite the severe medical and socioeconomic consequences of fragility fractures, treatment and prevention efforts remain inadequate, particularly in the oldest and highest-risk patients. Osteoporosis is still viewed as an inevitable consequence of aging, rather than an opportunity for treatment and prevention. Multiple factors contribute to the failure of initiating appropriate treatment for osteoporosis, even in patients with fragility fractures. Our review offers an overview of the current literature and offers answers common issues in the management of osteoporosis in older adults.

Long-term results of the augmented PFNA: a prospective multicenter trial

BACKGROUND

Pertrochanteric fractures are increasing and their operative treatment remains under discussion. Failures needing reoperations such as a cut-out are reported to be high and are associated with multiple factors including poor bone quality, poor fracture reduction and improper implant placement. The PFNA(®) with perforated blade offers an option for standardized cement augmentation with a PMMA cement to provide more stability to the fracture fixation. It remains unclear if the augmentation of this implant does any harm in a longer time span. This prospective multicenter study shows clinical and radiological results with this implant with a mean follow-up time of 15 months.

METHODS

In 5 European clinics, 62 patients (79 % female, mean age 85.3 years) suffering from an osteoporotic pertrochanteric fracture (AO 31) were treated with the augmented PFNA(®). The primary objectives were assessment of activities of daily living, pain and mobility. Furthermore, the X-rays were analyzed for the cortical thickness index, changes of the trabecular structure around the cement and the hip joint space.

RESULTS

The mean follow-up time was 15.3 months. We observed callus healing in all cases. The surgical complication rate was 3.2 % with no complication related to the cement augmentation. A mean volume of 3.8 ml of cement was injected and no complication was reported due to this procedure. 59.9 % reached their prefracture mobility level until follow-up. The mean hip joint space did not change significantly until follow-up and there were no signs of osteonecrosis in the follow-up X-rays. Furthermore, no blade migration was assessed.

CONCLUSION

This study makes us believe that the standardized augmentation of the PFNA with a perforated blade is a safe method to treat pertrochanteric femoral fractures. It leads to good functional results and is not associated with cartilage or bone necrosis.

Literature review of outcome parameters used in studies of Geriatric Fracture Centers

INTRODUCTION

A variety of multidisciplinary treatment models have been described to improve outcome after osteoporotic hip fractures. There is a tendency toward better outcomes after implementation of the most sophisticated model with a shared leadership for orthopedic surgeons and geriatricians; the Geriatric Fracture Center. The purpose of this review is to evaluate the use of outcome parameters in published literature on the Geriatric Fracture Center evaluation studies.

MATERIALS AND METHODS

A literature search was performed using Medline and the Cochrane Library to identify Geriatric Fracture Center evaluation studies. The outcome parameters used in the included studies were evaluated.

RESULTS

A total of 16 outcome parameters were used in 11 studies to evaluate patient outcome in 8 different Geriatric Fracture Centers. Two of these outcome parameters are patient-reported outcome measures and 14 outcome parameters were objective measures.

CONCLUSION

In-hospital mortality, length of stay, time to surgery, place of residence and complication rate are the most frequently used outcome parameters. The patient-reported outcomes included activities of daily living and mobility scores. There is a need for generally agreed upon outcome measures to facilitate comparison of different care models.

Identifying a standard set of outcome parameters for the evaluation of orthogeriatric co-management for hip fractures

BACKGROUND AND PURPOSE

Osteoporotic fractures are an increasing problem in the world due to the ageing of the population. Different models of orthogeriatric co-management are currently in use worldwide. These models differ for instance by the health-care professional who has the responsibility for care in the acute and early rehabilitation phases. There is no international consensus regarding the best model of care and which outcome parameters should be used to evaluate these models. The goal of this project was to identify which outcome parameters and assessment tools should be used to measure and compare outcome changes that can be made by the implementation of orthogeriatric co-management models and to develop recommendations about how and when these outcome parameters should be measured. It was not the purpose of this study to describe items that might have an impact on the outcome but cannot be influenced such as age, co-morbidities and cognitive impairment at admission.

METHODS

Based on a review of the literature on existing orthogeriatric co-management evaluation studies, 14 outcome parameters were evaluated and discussed in a 2-day meeting with panellists. These panellists were selected based on research and/or clinical expertise in hip fracture management and a common interest in measuring outcome in hip fracture care.

RESULTS

We defined 12 objective and subjective outcome parameters and how they should be measured: mortality, length of stay, time to surgery, complications, re-admission rate, mobility, quality of life, pain, activities of daily living, medication use, place of residence and costs. We could not recommend an appropriate tool to measure patients' satisfaction and falls. We defined the time points at which these outcome parameters should be collected to be at admission and discharge, 30 days, 90 days and 1 year after admission.

CONCLUSION

Twelve objective and patient-reported outcome parameters were selected to form a standard set for the measurement of influenceable outcome of patients treated in different models of orthogeriatric co-managed care.

Surgeons save bones: an algorithm for orthopedic surgeons managing secondary fracture prevention

Postmenopausal osteoporosis has a big impact on health care budget worldwide, which are expected to double by 2050. In spite of severe medical and socioeconomic consequences from fragility fractures, there are insufficient efforts in optimizing osteoporotic treatment and prevention. Undertreatment of osteoporosis is a well known phenomenon, particularly in elderly patients. Treatment rates remain low across virtually all patient, provider, and hospital-level characteristics, even after fragility fractures. In-hospital initiation is one of the options to increase treatment rates and improve osteoporosis management. However, multiple factors contribute to the failure of initiating appropriate treatment of osteoporosis in patients with fragility fractures. These include a lack of knowledge in osteoporosis and an absence of a comprehensive treatment guideline among family physicians and orthopedic surgeons. Furthermore, orthopedic surgeons are hardly willing to accept their responsibility for osteoporosis treatment due to the fact that they are usually not familiar with the initiation of specific drug treatments. The presented algorithm offers trauma surgeons and orthopedic surgeons a safe and simple guided pathway of treating osteoporosis in postmenopausal women appropriately after fragility fractures based on the current literature. From our point of view, this algorithm is useful for almost all cases and the user can expect treatment recommendations in more than 90 % of all cases. Nevertheless, some patients may require specialized review by an endocrinologist. The proposed algorithm may help to increase the rate of appropriate osteoporosis treatment hence reducing the rates of fragility fractures.

Is augmentation a possible salvage procedure after lateral migration of the proximal femur nail antirotation?

INTRODUCTION

Failed fracture fixation of proximal femur fractures in the elderly usually results in prosthetic replacement. In case of the proximal femur nail antirotation (PFNA), during lateral blade migration or periimplant fracture at the femoral shaft, the femoral head remains intact and therefore a joint preserving procedure might be performed. However, implant anchorage in the femoral head after the second blade implantation generally results in reduced anchorage in the remaining cancellous bone. Therefore, we hypothesize that in the above mentioned cases augmentation of the PFNA blade could be a treatment option before prosthetic surgery has to be performed.

MATERIALS

Biomechanical investigations were performed in eight fresh frozen femoral heads. Implant anchorage in case of blade extraction and reinsertion was investigated by rotation and pull out of a PFNA blade with a servohydraulic testing machine. After reinsertion of the blade and augmentation with bone-cement, the anchorage of the blade was investigated again to observe changes in torque and pull-out force.

RESULTS

Rotational stability of the implant significantly increased after augmentation of the prior extracted PFNA blade. Pull-out strength was higher in the revised case than in the initial tests but without statistical significance. After augmentation, correlation between bone mineral density and pull-out strength which was found during initial pull-out disappeared.

DISCUSSION

Augmentation of simulated blade exchange after lateral blade migration demonstrated a good anchorage. There was superior rotational stability in the revised case and no inferiority during pull out for the investigated specimens. Furthermore, augmentation could compensate for destroyed trabeculae and poor bone stock. It could furthermore be an option when a failed implant has to be replaced by a long PFNA in case of shaft fracture at the tip of the implant to increase anchorage in the femoral head. From a biomechanical point of view, reosteosynthesis and augmentation in selected cases of PFNA revision could be an alternative to initial prosthetic replacement. In the case of cut-out or medial implant protrusion, the suggested salvage technique is not feasible.

Functional outcome and mortality in geriatric distal femoral fractures

BACKGROUND

Fragility fractures are a major health care problem worldwide. Due to the ageing population an increase of distal femoral fractures is to be expected. We studied the long-term functional outcome and their influencing factors in geriatric patients with LISS-plated distal femoral fractures.

PATIENTS AND METHODS

A cohort study with functional long-term follow up examination was carried out in a level one trauma centre on distal femoral fracture patients 65 years and older. Of 53 consecutive patients who were treated in our hospital, 43 patients with a mean age of 80 years met our inclusion criteria. 48.8% died within the study period of 5.3 years. On the remaining patients the residential status, the Barthel index and the Parker score were assessed.

RESULTS

The mean Barthel index was 47.7 and the mean Parker score was 3.5. 23% were found to be totally housebound and 26% were not able to perform any social activity. Only 18% were able to walk unaided. Patients with any medical complication had significantly higher mortality rates. Patients with extraarticular fractures had better mobility scores. Nursing home residents showed higher mortality rates but compared to patients coming from their own home the difference regarding Barthel and Parker scores remained non-significant.

CONCLUSION

This study documents the poor functional long-term outcome of geriatric patients with distal femoral fractures. In comparison to other fragility fracture patients it seems that this population is at higher risk to die in-hospital during their perioperative course. Medical complications have to be avoided as they were found to be associated with worse functional outcome and higher mortality rates. An osteoporosis therapy may be associated with reduced mortality rates also in these patients.

The Tyrolean Geriatric Fracture Center: an orthogeriatric co-management model

BACKGROUND

The aging population is growing rapidly and this change results in an increase in the number of fragility fracture patients. Several reports describe their poor outcome. Integrated models of care have been published in order to improve quality of patient care. We established an orthogeriatric model of care at the Department of Trauma Surgery in Innsbruck in cooperation with the Department of Geriatric Medicine (Hochzirl) and the Department for Anesthesiology. This report describes our concept as well as initial experience.

PATIENTS AND METHODS

We included all geriatric patients according to the definition of the German Geriatric Society. In all patients, basic demographic data, Charlson Comorbidity Index, and type of fracture were recorded. Main principles of the newly implemented system are the integration of a geriatrician in our team of trauma surgeons and anesthesiologists, prioritization of patients, development of our own clinical treatment guidelines, regular interdisciplinary and interprofessional meetings, a special outpatient clinic for these patients, and the better cooperation with the nearby Department of Geriatric Medicine.

RESULTS

A total of 529 patients met our inclusion criteria during 2010; 77.4% were female and the mean age was 84.1 years. The overall medical complication rate was 20.4%. Of the patients, 36.1% had hip fractures and 70.5% could be operated mainly using spinal anesthesia within 24 h and their mean length of stay was significantly shorter than operations performed 5 years previously. At 3 months, 86.7% of the patients had returned home and, thus, had reached their prefracture residency.

CONCLUSION

A coordinated, multidisciplinary model for the treatment of fragility fractures has the potential to improve the quality of patient care. Several international studies report superior outcome and our own findings are promising as well. We could show that our major goals, e.g., reduction of complications, shortening the length of stay, and restoration of the prefracture residency, can be improved by implementing such a model.

Standardised cement augmentation of the PFNA using a perforated blade: A new technique and preliminary clinical results. A prospective multicentre trial

Pertrochanteric fractures are a rising major health-care problem in the elderly and their operative stabilisation techniques are still under discussion. Furthermore, complications like cut-out are reported to be high and implant failure often is associated with poor bone quality. The PFNA(®) with perforated blade offers a possibility for standardised cement augmentation using a polymethylmethacrylate (PMMA) cement which is injected through the perforated blade to enlarge the load-bearing surface and to diminish the stresses on the trabecular bone. The current prospective multicentre study was undertaken to evaluate the technical performance and the early clinical results of this new device. In nine European clinics, 59 patients (45 female, mean age 84.5 years) suffering from an osteoporotic pertrochanteric fracture (Arbeitsgemeinschaft für Osteosynthesefragen, AO-31) were treated with the augmented PFNA(®). Primary objectives were assessment of operative and postoperative complications, whereas activities of daily living, pain, mobility and radiologic parameters, such as cement distribution around the blade and the cortical thickness index, were secondary objectives. The mean follow-up time was 4 months where we observed callus healing in all cases. The surgical complication rate was 3.4% with no complication related to the cement augmentation. More than one-half of the patients reached their prefracture mobility level within the study period. A mean volume of 4.2ml of cement was injected. We did not find any cut-out, cut through, unexpected blade migration, implant loosening or implant breakage within the study period. Our findings lead us to conclude that the standardised cement augmentation using the perforated blade for pertrochanteric fracture fixation enhances the implant anchorage within the head-neck fragment and leads to good functional results.

Neuroaxial versus general anaesthesia in geriatric patients for hip fracture surgery: does it matter?

The influence of the mode of anaesthesia on outcome of geriatric patients with hip fractures is a controversial issue in the medical literature. In the light of an ageing society, a conclusive answer to this question is of growing importance. The purpose of this review was to assess the effect of neuroaxial and general anaesthesia on mortality and morbidity in geriatric patients sustaining a hip fracture. Following a current literature search within the Pubmed and Cochrane database (1967-2010), 34 randomised controlled trials, 14 observational studies and eight reviews/meta-analysis publications were included. Potentially outcome-influencing factors such as mortality, deep vein thrombosis, pulmonary embolism, postoperative confusion and other anaesthesia-related outcomes were evaluated. After analysing the current literature with 56 references, covering 18,715 patients with hip fracture, it can be concluded that spinal anaesthesia is associated with significantly reduced early mortality, fewer incidents of deep vein thrombosis, less acute postoperative confusion, a tendency to fewer myocardial infarctions, fewer cases of pneumonia, fatal pulmonary embolism and postoperative hypoxia. General anaesthesia has the advantages of having a lower incidence of hypotension and a tendency towards fewer cerebrovascular accidents compared to neuroaxial anaesthesia. Otherwise, general anaesthesia and respiratory diseases were significant predictors of morbidity in hip fracture patients. These data suggest that regional anaesthesia is the preferred technique, but the limited evidence available does not permit a definitive conclusion to be drawn for mortality or other outcomes. For hip fracture surgery, the choice of anaesthesia (general or neuroaxial) is made by the anaesthesiologist and is based on the patient's preference, comorbidities, potential general postoperative complications and the clinical experience of the anaesthesiologist. The overall therapeutic approach in hip fracture care should be determined jointly by the orthopaedic surgeon, the geriatrician and the anaesthesiologist (multidisciplinary approach).

Outcome in geriatric fracture patients and how it can be improved

Geriatric fractures are an increasing medical problem worldwide. This article wants to give an overview on the literature concerning the outcome to be expected in geriatric fracture patients and what can be done to improve it. In literature, excess mortality rates vary from 12% to 35% in the first year after a hip fracture, and also, other geriatric fractures seem to reduce the patient's remaining lifetime. Geriatric fractures and, in particular, hip fractures constitute a major source of disability and diminished quality of life in the elderly. Age, gender, comorbid conditions, prefracture functional abilities, and fracture type have an impact on the outcome regarding ambulation, activities of daily living, and quality of life. Comprehensive orthogeriatric comanagement might improve the outcome of geriatric fracture patients. For the future, well designed, large prospective randomized controlled trials with clear outcome variables are needed to finally prove the effectiveness of existing concepts.

Ortho-geriatric service--a literature review comparing different models

In the fast-growing geriatric population, we are confronted with both osteoporosis, which makes fixation of fractures more and more challenging, and several comorbidities, which are most likely to cause postoperative complications. Several models of shared care for these patients are described, and the goal of our systematic literature research was to point out the differences of the individual models. A systematic electronic database search was performed, identifying articles that evaluate in a multidisciplinary approach the elderly hip fracture patients, including at least a geriatrician and an orthopedic surgeon focused on in-hospital treatment. The different investigations were categorized into four groups defined by the type of intervention. The main outcome parameters were pooled across the studies and weighted by sample size. Out of 656 potentially relevant citations, 21 could be extracted and categorized into four groups. Regarding the main outcome parameters, the group with integrated care could show the lowest in-hospital mortality rate (1.14%), the lowest length of stay (7.39 days), and the lowest mean time to surgery (1.43 days). No clear statement could be found for the medical complication rates and the activities of daily living due to their inhomogeneity when comparing the models. The review of these investigations cannot tell us the best model, but there is a trend toward more recent models using an integrated approach. Integrated care summarizes all the positive features reported in the various investigations like integration of a Geriatrician in the trauma unit, having a multidisciplinary team, prioritizing the geriatric fracture patients, and developing guidelines for the patients' treatment. Each hospital implementing a special model for geriatric hip fracture patients should collect detailed data about the patients, process of care, and outcomes to be able to participate in audit processes and avoid peerlessness.

Comparison of skeletal muscle strength between cardiac patients and age-matched healthy controls

The purpose of the present study was to compare muscular strength of knee extensors and arm flexor muscles of cardiac patients (n = 638) and healthy controls (n = 961) in different age groups. Isometric torques were measured in a sitting position with the elbow, hip, and knee flexed to 90(0). For statistical analysis, age groups were pooled in decades from the age of 30 to 90 years. Additionally, the influence of physical lifestyle prior to disease on muscular strength was obtained in the patients. For statistical analysis three-way ANOVA (factors age, gender, and physical activity level) was used.Both in patients and in controls a significant age-dependent decline in maximal torque could be observed for arm flexors and knee extensors. Maximal leg extensor muscle showed statistically significant differences between healthy controls and cardiac patients as well as between subgroups of patients: Physically inactive patients showed lowest torques (male: 148 +/- 18 Nm; female: 82 +/- 25 Nm) while highest values were measured in control subjects (male: 167 +/- 16 Nm; female: 93 +/- 17 Nm). In contrast, arm flexor muscles did not show any significant influence of health status or sports history.This qualitative difference between weight-bearing leg muscles and the muscle group of the upper extremity suggest that lower skeletal muscle strength in heart patients is mainly a consequence of selective disuse of leg muscles rather than any pathological skeletal muscle metabolism. Since a certain level of skeletal muscle strength is a prerequisite to cope with everyday activities, strength training is recommended as an important part of cardiac rehabilitation.
