Geriatric patients with dementia show increased mortality and lack of functional recovery after hip fracture treated with hemiprosthesis

Hemoglobin level, degree of mobilization, and pneumonia are associated with the development of postoperative delirium in cemented hemiarthroplasty after femoral neck fracture

PURPOSE

The aim of this retrospective study was to identify independent prognostic factors for developing a postoperative delirium (POD) in patients suffering from a proximal femoral neck fracture and treated by implantation of a hemiprosthesis.

METHODS

A retrospective study, including patients with hip hemiarthroplasty due to a femoral neck fracture between 2011 and 2020 was performed. Demographic data, preexisting conditions, intra-/postoperative complications, mobilization and laboratory results were extracted from the patients' charts. The different parameters were analyzed comparing patients with and without POD.

RESULTS

412 patients, mean age of 81 ± 9.58 years were included, 66.5% (n = 274) were female, 18.2% (n = 75) of them developed a POD. Significantly higher incidence of POD was associated with older age (p < 0.001), lower level of haemoglobin (p < 0.001), higher post-surgery interleukin 6 (IL 6) level (p = 0.008), higher postoperative level of leukocytes (p = 0.01). Patients with POD received more units of packed red blood cells (PRBC) (p = 0.007). Patients with no mobility limitations pre-operatively developed POD less frequently (p = 0.01), whereas suffering from pneumonia (p = 0.03) or limited mobility postoperatively increased the risk of POD (p < 0.001).

CONCLUSION

This study could help to identify patients with a risk for developing POD after a hemiarthroplasty in femoral neck fractures. As a consequence, frequent controls of Hb, IL 6 and leucocytes levels to avoid anemia and infections, as well as the well surgical treatment to guarantee a good postoperative outcome.

Hip Fractures in Patients with Dementia: An Emerging Orthopedic Concern

Hip fractures are a very common injury in the elderly population associated with an increased mortality rate. Currently, more and more elderly patients are diagnosed with dementia. Demented patients are more prone to falls and hip fractures compared to the general population because of conditions related to their disease such as instability, osteoporosis, poor muscle control and weakness. The coexistence of dementia and hip fractures is a difficult situation for both the patients and the treating physicians because of postoperative complications in this frail subgroup of patients and their inability to stand up and walk. To enhance the literature, we reviewed published studies of hip fracture patients suffering from dementia to discuss why they have more frequent hip fractures, to review their associated in-hospital complications, and to emphasize on their postoperative management to be able to reach the pre-injury activity level and optimal quality of life.

Orthogeriatric care-outcome of different fragility fractures

INTRODUCTION

Fragility fractures (FF) are associated with increased morbidity and mortality and reflect a dramatic turning point in the life of older adults. The scientific discourse is dominated by proximal femoral fractures, but FF affect multiple parts of the body and often precede hip fractures. Orthogeriatric co-management has multiple shown to improve patient's outcome. We hypothesize that all geriatric patients with FF benefit from orthogeriatric co-management.

MATERIALS AND METHODS

We retrospectively evaluated all patients over 70 years with FF (hip joint, periprosthetic, spine, pelvic ring, and humerus) of our geriatric trauma center for the years 2019-2021, who received orthogeriatric co-management. Demographic data, fracture type, complications, discharge modality and in-hospital mortality were recorded. For patients transferred to geriatrics, the Barthel Index (BI) and the discharge modality were recorded. Primary outcome parameters were discharge modality and BI difference. Secondary outcome parameters were complication rates and in-hospital mortality. Logistic regression analysis was performed.

RESULTS

555 patients (83.8 ± 6.5 years, 182 males, 373 females) were evaluated. 245 (44.1%) patients were referred to geriatrics for further orthogeriatric treatment. Positive predictors were age, surgery, and a high Charlson Comorbidity Index. The overall in-hospital mortality was 8.6% (n = 48) (5.8% (n = 32) during acute trauma care and 6.5% (n = 16) during stay in geriatrics). The mortality rate of nursing home residents was significantly higher compared to patients living at home (10.4% vs. 5.6%). The rate of non-surgical complications was 44.5%. 26.9% of patients living at home were discharged to a nursing home, while 51.3% were able to return home. The risk of admission to a nursing home was reduced for thoracolumbar fractures (OR = 0.22) and increased markedly for periprosthetic fractures (OR = 3.95). During orthogeriatric treatment, all fractures showed a significant increase in BI. Patients living at home benefited more than nursing home residents (20.5 ± 19.5 vs. 8.7 ± 18.0 points). The chance of a BI increase (> 19 points) was increased for hip and pelvic ring fractures. Devastating results showed patients with dementia. In comparison, mentally healthy patients had a 4.5-fold increased chance of increasing their BI (> 19 points).

CONCLUSIONS

Presented data shows that all patients with FF are at high risk for complications and could benefit from standardized orthogeriatric management. Modern patient care requires a holistic orthogeriatric approach to improve patient's outcome.

Early Surgical Care of Anticoagulated Hip Fracture Patients Is Feasible-A Retrospective Chart Review of Hip Fracture Patients Treated with Hip Arthroplasty within 24 Hours

Anticoagulative medication such as antiplatelet drugs (PAI, acetylsalicylic acid and direct platelet aggregation inhibitors), vitamin-K-antagonist Warfarin (VKA) or direct oral anticoagulants (DOAC) are common among hip fracture patients, and the perioperative management of these patients is a rising challenge in orthopaedic trauma. Our objective was to determine the effect of oral anticoagulation in patients receiving early endoprosthetic treatment within 24 h after their admission. For the period from 2016 to 2020, a retrospective chart review of 221 patients (mean age 83 ± 7 years; 161 women and 60 men) who were treated either with hemi- (n = 209) or total hip arthroplasty (n = 12) within 24 h after their admission was performed. We identified 68 patients who took PAI, 34 who took DOAC and 9 who took VKA medications. The primary outcome measures were the transfusion rate and the pre- and postoperative haemoglobin (Hb) difference. The secondary outcome measures were the in-patient mortality and the rate of postoperative haematomas that needed operative treatment. A logistic/ordinal regression was performed considering the related variables to prevent cofounding occurring. The mean time to surgery was significantly longer for the DOAC and VKA groups when they were compared to the controls (none 14.7 ± 7.0 h; PAI 12.9 ± 6.7 h; DOAC 18.6 ± 6.3 h; VKA 19.4 ± 5.5 h; p < 0.05). There was no difference in the preoperative Hb level between the groups. Overall, 62 patients (28%) needed blood transfusions during the in-patient stay with an ASA classification (p = 0.022), but the type of anticoagulative medication was not a significant predictor in the logistic regression. Anticoagulation with DOAC and grouped surgery times were positive predictors for a higher Hb difference in the patients who did not undergo an intraoperative blood transfusion (n = 159). Postoperative haematomas only occurred in patients taking anticoagulative medication (four cases in PAI group, and three cases in DOAC group), but the logistic regression showed that the anticoagulative medication had no effect. The in-patient mortality was significantly influenced by a high ASA grade (p = 0.008), but not by the type of anticoagulative medication in patients who were treated within 24 h. We conclude that the early endoprosthetic treatment of the anticoagulated hip fracture patient is safe, and a delayed surgical treatment is no longer justifiable.

Early Results in Non-Displaced Femoral Neck Fractures Using the Femoral Neck System

Introduction

Femoral neck fractures in the elderly are a major event and are rising in incidence over the last decade. Advancing age and numerous comorbidities largely account for high mortality rate and require geriatric expertise. Treatment options are total hip arthroplasty (THA), hemiarthroplasty (HA) or osteosynthesis. Literature suggests THA or HA for better outcomes, although no clear guidelines exist.

Material and methods

A retrospective chart review was performed of 63 patients (80 ± 11 years; 32 women, 31 men) with Garden one femoral neck fractures treated between June 2018 and June 2020 with either HA or internal fixation with the Femoral Neck System (FNS). Primary outcome measures were surgical and non-surgical complication rates and best achievable mobilization during the hospital stay.

Results

Thirty four patients were treated with HA, and 29 with the FNS. Mobilization was measured using the Charité Mobility Index (CHARMI). No difference between age, ASA, CCI or preoperative CHARMI was found. The CHARMI was significantly lower in the HA group. No difference in surgical complications was found. The HA cohort showed more non-surgical complications, a longer ICU stay and more blood transfusions. Hospitalization was significant longer in the HA than the FNS cohort (15.1 ± 5.1 vs 9.8 ± 3.8 days). Radiographic controls were performed after 6 and 12 weeks. The FNS group showed a mean shortening of 3.3 mm. 4 of 21 patient had shortening >5 mm. 20 of 21 patients showed radiographic signs of bone healing after 3 months.

Conclusion

Early results with the FNS show faster recovery than patient with hemiarthroplasty. Internal fixation with the FNS may be an option in non-displaced femoral neck fractures. Further studies should be performed to better evaluate the FNS compared to traditional internal fixation methods and arthroplasty.
