Clinical Outcomes and Radiologic Characteristics of Insufficiency Femoral Neck Fracture in Elderly Patients

Analysis of vertical and horizontal offsets in displaced femoral neck fracture in elderly treated with indigenous bicentric bipolar hip device

ObjectivesTo analyze the effect of indigenous bicentric bipolar prosthesis on horizontal and vertical offsets in fracture neck of femur when compared to contralateral normal hip and to evaluate functional outcomes. We hypothesized that our non-modular bipolar device restores satisfactory offsets in such patients. MethodsAll active elderly patients with displaced fracture NOF having contralateral normal hip were included. We used an indigenous bicentric bipolar hip-prosthesis, which is a non-modular single-piece device in all cases by lateral Hardinge approach. Postoperative radiograph AP view was taken in 15° internal rotation to decrease the effect of limb rotation on offset. CT scan was also used to evaluate offsets using ADW4.6 ADVANCED GE optima 128 slice software system. Subjects were followed for a minimum of 12 months postoperatively and functional outcome of effect of offsets change were evaluated by modified Harris Hip Score. ResultsThere is minimal difference in horizontal and vertical offset after bicentric bipolar hemi-replacement which is statistically insignificant supporting our hypothesis. The clinical outcomes were good to fair according to modified Harris Hip Score. The mean value of horizontal offset after our bipolar hemireplacement was 42.4 ± 2.04 mm and of normal hip was 41.8 ± 1.81 mm and P-value=0.08 in plain radiographs and value of horizontal offset in CT scan was 40.73 ± 0.27on bipolar side and 41.19 ± 0.77 on normal side. Vertical offset after bicentric bipolar was 32.67 ± 2.85 mm and vertical offset of normal hip was 32.53 ± 2.73 mm. Mean 9.77 ± 1.09 mm of calcar was preserved. Modified Harris Hip Score at 6 and 12 months postoperatively was 75.78 ± 4.16 and 79.53 ± 3.95 respectively. There was no incidence of hip dislocation. ConclusionOur study data clearly demonstrates that vertical and horizontal offsets are effectively maintained by the indigenous bicentric hip device. There was insignificant change in offsets as compared to contralateral normal side due to its design modifications. Indigenous bicentric non-modular bipolar device offers an excellent option for femur neck fractures in elderly patients in resource constrained situations. It allows rapid rehabilitation due to reduced surgical time, minimal blood loss and early return to function and activities of daily living.

Cemented and uncemented hemiarthroplasty for femoral neck fracture in elderly patients: a systematic review and meta-analysis.

Cemented hemiarthroplasty to treat femoral neck fractures (FNFs) in elderly patients is controversial. Therefore, this study aimed to compare cemented vs uncemented outcomes. A literature review using Pubmed, EMBASE, Cochrane Library, and Science Citation Index databases was conducted. Studies comparing outcomes of cemented with uncemented hemiarthroplasty for FNFs in elderly patients up to March 2020 were included. Dichotomous outcomes were pooled and reported as relative risk (RR) or odds ratio (ORs), while continuous outcomes were pooled and reported as the mean difference (MD) or standardized mean difference (SMD). The analysis included 39 studies with a total of 112 576 patients. Pooled analysis revealed that compared with cemented, patients with uncemented intervention had better outcomes for intraoperative blood loss (OR 0.19; 95% CI 0.01-0.37), systolic blood pressure (OR 2.83; 95% CI 1.51-5.28), surgery duration (SMD, 0.51; 95% CI 0.2-0.81), length of anesthesia (OR 0.28; 95% CI 0.11-0.45), 6-month mortality (OR 1.11; 95% CI 1.03-1.2), cardiovascular accidents (OR 2.14; 95% CI 1.07-4.28), respiratory failure (OR 8.26; 95% CI 1.38-49.4), fat embolisms (OR 1.58; 95% CI 1.29-1.93), and heterotrophic ossification (OR 2.3; 95% CI 1.3-4.06), but more intraoperative accidents (OR 0.34; 95% CI 0.26-0.45), postoperative fractures (OR 0.27; 95% CI 0.21-0.34), reoperations (OR 0.59; 95% CI 0.53-0.65), and revisions (OR 0.62; 95% CI 0.44-0.88). Meta-analysis of hemiarthroplasty outcomes shows that elderly patients who underwent uncemented vs cemented procedures had better results for several factors that are important for not only improved recovery in elderly populations, but also more intraoperative and postoperative risks.

Cemented versus uncemented total hip replacement for femoral neck fractures in elderly patients: a retrospective, multicentre study with a mean 5-year follow-up

BackgroundCemented or uncemented total hip replacement (CTR or UTR) for femoral neck fractures (AO/OTA type 31B/C) is a relatively common procedure in elderly individuals. The recent literature is limited regarding long-term outcomes following CTR versus UTR in the Asian population.MethodsUsing our institutional database, we performed long-term outcome analysis on 268 patients with femoral neck fractures (AO/OTA type 31B/C) who had undergone a primary UTR or CTR (CTR: n = 132, mean age, 67.43 ± 6.51 years; UTR: n = 136, mean age, 67.65 ± 6.13 years) during 2007–2014, and these patients were followed until 2019. Follow-up occurred 1, 3, 6, and 12 months postoperatively and yearly thereafter. The primary endpoint was the Harris hip score (HHS); the secondary endpoint was the incidence of orthopaedic complications.ResultsThe mean follow-up time was 62.5 months (range, 50.1–76.1 months). At the final follow-up, the HHS was 79.39 ± 16.92 vs 74.18 ± 17.55 (CTR vs UTR, respectively, p = 0.011). Between-group significant differences were observed regarding the incidence of prosthesis revision, prosthesis loosening, and periprosthetic fracture (7.6% [95% CI, 6.4–8.2] for CTR vs 16.9% [95% CI, 14.7–17.3] for UTR, p = 0.020; 9.8% [95% CI, 8.3–10.7] for CTR vs 19.9% [95% CI, 18.2–20.9] for UTR, p = 0.022; 5.3% [95% CI, 4.4–6.7] for CTR vs 13.2% [95% CI, 12.1–13.8] for UTR, p = 0.026, respectively).ConclusionCTR showed superiority to UTR by improving the HHS and decreasing the incidence of orthopaedic complications. Our findings need to be confirmed in a prospective, randomized controlled study to verify whether they can be applicable to a broader population.

Clinical Outcomes of Total Hip Arthroplasty for Displaced Femoral Neck Fractures in Patients 80 Years of Age and Older Selected by Clinical Frailty Score.

PurposeThe utility of total hip arthroplasty (THA) for the treatment of displaced femoral neck fractures in elderly patients (≥80 years of age) remains controversial as a patient's general condition is an essential factor impacting recovery. This study aims to determine if THA is a valuable option for appropriately selected elderly patients.Materials and MethodsAll patients underwent cementless THA using a direct lateral approach with a rectangular stem. Eighty-two patients ≥80 years of age underwent THA due to a displaced femoral neck. Clinical frailty scale (CFS) scores <5 were indicated for THA. The modified Harris hip score (mHHS), visual analogue scale (VAS), and patient satisfaction were used to assess outcomes.ResultsNine of 82 patients died in the study period with another underlying disease. One, a 90-year-old male with pneumonia expired in the intensive care unit at 7-day postoperatively, while the other eight died due to causes unrelated to THA. Of the remaining 73 patients: (i) mean mHHS score increased to 80.57±21.36 at 1-year postoperatively; (ii) VAS was 2.3±0.9 points six-months postoperatively; and (iii) 78.7% of patients reported that they were very satisfied or satisfied 1-year postoperatively. The number of perioperative complications was 10.8% (9 hips) without the need for revision surgery.ConclusionThe use of THA in patients ≥80 years of age with low CFS scores (<5) described here yielded favorable results and a relatively low rate of complications. However, a well-controlled comparative study or randomized trial is required to further refine selection criteria for THA in this patient population.

Uncemented versus cemented total hip arthroplasty for displaced femoral neck fractures in elderly patients with osteoporosis: A retrospective analysis.

ObjectiveThis study was performed assess the clinical outcomes of elderly patients with osteoporotic femoral neck fractures (FNFs) (AO/OTA: 31B/C) treated by initial uncemented total hip arthroplasty (UTA) or cemented total hip arthroplasty (CTA).MethodsThis study involved consecutive elderly patients with osteoporotic FNFs (AO/OTA: 31B/C) treated by initial UTA or CTA in our medical centre from 2010 to 2015. The primary outcomes were the Harris hip score (HHS) and the rates of revision, loosening, periprosthetic fracture, and dislocation.ResultsIn total, 224 patients were included in the final analysis (UTA, n = 114; CTA, n = 110). The mean follow-up duration was 60 months (range, 32–68 months). The mean HHS was 75.34 ± 18.82 for UTA and 80.12 ± 17.83 for CTA. Significant dissimilarities were detected in the rates of revision, loosening, and periprosthetic fracture between UTA and CTA (14.0% vs. 5.5%, 20.2% vs. 10.0%, and 12.3% vs. 4.5%, respectively). A significant difference was also detected in the probability of revision between the two groups.ConclusionElderly patients with osteoporotic FNFs (AO/OTA: 31B/C) treated with CTA show greater improvements in functional outcomes and key orthopaedic complications than those treated with UTA.

Complications after internal screw fixation of nondisplaced femoral neck fractures in elderly patients: A systematic review.

Internal fixation with cannulated screws for nondisplaced femoral neck fractures in the elderly has substantial reoperation and mortality rates. The selection of either internal fixation or arthroplasty for nondisplaced femoral neck fracture is debatable. We performed a systematic review of the literature regarding complications in the internal fixation of nondisplaced femoral neck fractures in elderly (>60 years old) patients. We searched in multiple databases (PubMed, Web of Science, Embase, and Cochrane Library) for articles in this area; there was no limitation over the publication year. A total of 1971 patients were identified from 16 published studies. All these patients were over 60 years old. The minimum follow-up after the surgical procedure was 11 months (range: 11-183 months). A total of 329 fractures (16.7%) with radiographic and clinical failures after fixation were identified with regard to stable femoral neck fractures. The single most common complication after surgery was nonunion (129/329), with a pooled percentage of 39.2%. Osteonecrosis was found to be the second most common cause of revision surgery (31.9%). The overall reoperation rate attributable to surgical complications was 15.2% (300/1971 patients). Conversion to hip arthroplasty was performed in 244 patients (12.4%) after primary fixation. Our study elucidated further the complication rate of nondisplaced femoral neck fractures treated with internal screw fixation. Since the failure rate of screw fixation for stable femoral neck fractures in elderly patients is not low, we believe that hemiarthroplasty is a reasonable treatment option in select patients. Level III, Therapeutic study.

Trunk Skeletal Muscle Mass and Phase Angle Measured by Bioelectrical Impedance Analysis are Associated with the Chance of Femoral Neck Fracture in Very Elderly People.

BackgroundThe study aimed to investigate the potential association of trunk skeletal muscle mass (tSM) and phase angle measured by bioelectrical impedance analysis (BIA) with the chance of femoral neck fractures in very elderly people.Patients and MethodsThis case-control study enrolled 78 femoral neck fracture patients aged over 75 years (29 males) and 1:2 matched healthy controls. All participants were subjected to BIA examination by specialists. tSM, the corrected values by height squared of tSM (tSMI) and phase angle were compared between fracture patients and controls. Multivariate logistic regression was performed to explore the strength of association of femoral neck fracture with tSM, tSMI, and phase angle.ResultstSM (kg) of fracture patients was significantly lower than those of controls in all participants (women: 13.49±0.42 vs 15.44±0.39, p<0.05; men: 15.30±0.71 vs 17.54±0.78, p<0.05). In the sarcopenic subgroup, fracture patients also got a lower tSM than controls (women: 12.58±0.21 vs 13.62±0.16, p<0.05; men:14.41±0.29 vs 16.07±0.21, p<0.05). The comparison of tSMI between the two groups was similar to that of tSM. Phase angle (°) at 50 kHz in fracture patients was significantly lower than that of controls in women and men (women: 3.70±0.32 vs 4.61±0.21, p<0.05; men: 3.50±0.20 vs 3.84±0.22, p<0.05). Multivariate logistic regression analysis demonstrated higher fracture chance with significantly associated decreased tSM [women: OR (95% CI): 0.78(0.67–0.91); men: 0.74(0.64–0.86)] and tSMI [women: OR (95% CI): 0.72(0.61–0.85); men: 0.69 (0.59–0.81)]. In addition, per 1° increase of phase angle in the trunk could decrease the fracture risk by 14% for women [OR (95% CI): 0.86 0.79–0.94)] and 29% for men [OR (95% CI): 0.71 (0.64–0.79)].ConclusionThis study indicates a decrease in tSM, tSMI, and phase angle measured by BIA is significantly related to the increased chance of femoral neck fracture in people aged over 75 years. Strengthening the mass and strength of trunk skeletal muscles may help reduce the risk of femoral neck fracture in elderly patients.

Internal fixation versus hemiarthroplasty for displaced femoral neck fractures in the elderly: A cost-effectiveness analysis

BackgroundThere is little information on the cost and outcome of different treatments for femoral neck fractures. This study aimed to evaluate the cost-effectiveness of internal fixation compared with hemiarthroplasty (HA) for elderly patients with displaced femoral neck fractures. Materials and MethodsA total of 121 patients ≥ 65 years old were divided into internal fixation (n = 58) or HA group (n = 63). Clinical outcome was evaluated by the EuroQol 5 dimensions (EQ-5D) score at 3, 12, and 24 months. The total costs including medical and non-medical expense were collected through hospitalisation information, cost diaries, and telephone interviews. A cost-utility analysis of the total costs in combination with quality-adjusted life years (QALYs) calculated by EQ-5D and survival time was conducted. Results were expressed in incremental cost-effectiveness ratio (ICER). ResultsThe mean EQ-5D index score in the HA group were higher at the early follow-up (p<0.05). At 24 months there were no differences in EQ-5D between the 2 treatment groups (p>0.05). Over the 2-year period, patients treated with HA gained 0.09–0.10 more QALYs than those treated with internal fixation, while the mean total costs for internal fixation (CNY 55,676) were significantly lower than for HA (CNY 80,297) (P<0.001). ICER indicated that internal fixation may be more cost-effective than HA. ConclusionHA is associated with better outcome than internal fixation in the treatment of displaced femoral neck fractures in elderly patients. However, internal fixation may be more cost-effective because of less total cost.

Bipolar hemiarthroplasty for the treatment of femoral neck fractures with minimally invasive anterior approach in elderly

ObjectivesThe purpose of the study was to evaluate the efficacy of hemiarthroplasty with minimally invasive direct anterior approach (DAA) for the treatment of femoral neck fracture in elderly patients. We aimed to compare the DAA and the standard anterolateral approach (ALA), assessing multiple peri‑ and post-operative parameters. Design and settingBetween December of 2015 and May of 2017, patients operated with medial femoral neck fractures using bipolar hemiarthroplasty with DAA or ALA were evaluated. The volume of bleeding and transfusion, postoperative level of pain, mobilisation and functional outcome were assessed retrospectively. ParticipantsPatients between the age of 75 and 85, suffering Garden Type III Pauwels Type III and Garden Type IV medial femoral neck fractures were entered to the study. Patients had no history of anticoagulant therapy; the operation was performed in the first 48 h. All patients received similar postoperative pain management and physiotherapy. The type of implants was determined by the patients’ bone morphology and quality. Main outcome measuresThe outcomes of interest were the level of postoperative pain, blood loss, rate of recovery and physiotherapy, altered gait pattern and accuracy of leg length, related to DAA and ALA techniques. ResultsThe 51 patients operated with DAA showed significantly less pain, based on VAS (visual analogue scale), starting of the first postoperative day. Those patients who were subjected to DAA met with the criteria of hospital discharge 1.68 days earlier, compared to ALA patients. The length of leg was accurately set in 21% of ALA vs 54.9% of DAA patients. On the 12th week follow-up, limping was detected only 5.9% of DAA vs 46% of ALA groups. On the postoperative 2nd and 6th weeks, the HHS (Harris Hip Score) was significantly better in patients with DAA, compared to ALA (77 vs 65 and 91 vs 77, p < .05). ConclusionThe bipolar hemiarthroplasty with DAA allows earlier mobilisation, reduced postoperative pain and need for rehabilitation with an overall better functional outcome, compared to ALA. DAA is proven a reliable choice for femoral neck fractures, offering good outcome and faster recovery, similarly to total hip arthroplasties with degenerative arthritis.

Hemiarthroplasty compared with internal fixation for treatment of nondisplaced femoral neck fractures in elderly patients: a retrospective study

IntroductionInternal fixation (IF) with cannulated screws is the most widely accepted operation method for nondisplaced femoral neck fractures (FNFs) in elderly patients. However, there were higher rate of reoperation, severe complications and poorer functional outcomes reported in these patients treated with IF. The purpose of this research is to compare the prognosis, complications, reoperation and mortality of bipolar hemiarthroplasty (HA) with IF of cannulated screws in elderly patients. MethodsAll elderly patients (>75 years of age) with nondisplaced FNFs from January 2010 to December 2015 at our institution were included in this study. Patients treated with HA and IF with cannulated screws were compared. Outcome measures included the surgical complications, perioperative parameters, hip joint function, reoperation and mortality. ResultsThe blood loss of HA group (150.0 ± 55.1 mL) was statistically more than IF group (40.5 ± 15.7 mL, p = 0.001). However, the blood transfusion rate was similar between two groups (p = 0.102). At the last follow-up, there were total 14 (34.1%) severe surgical complications in the IF group, compared to 9 (10.1%) in the HA group (P = 0.001). No difference was detected between two groups with respect to the HHS and VAS at the last follow-up. Compared with the HA group, the IF group had much more reoperation in the follow up period (p = 0.001). There was no statistically differences of mortality rate between HA group (39.3%, 35/89) and IF group (34.1%, 14/41) (p=0.571). ConclusionsAs a treatment option for nondisplaced intracapsular FNFs in elderly patients, HA showed the merits of a less surgical complications and less reoperations, while IF demonstrated a shorter surgical time and less intraoperative blood loss. Meanwhile, there was no significant difference in the hip joint function and mortality rate in midterm follow-up. Further evaluation with a longer follow-up is recommended to strengthen these findings.

Non-operative predictors for subsequent interventions after intracapsular femoral neck fractures in elderly: A comprehensive analysis of the Hungarian nationwide health insurance database

ObjectivesTo investigate the correlation between non-operative prognostic factors and non-prosthetic fracture-related treatments following internal fixation of intracapsular femoral neck fractures in elderly patients. Design and settingRetrospective observational cohort study. Comprehensive analysis of the Hungarian nationwide health insurance database. ParticipantsData of in-patient records with S7200 ICD-10 codes were collected from the Hungarian National Health Insurance Fund Administration (HNHIFA) and from the health care provider institutes. The patients with femoral neck fractures in the year of 2000, following reduction and internal fixation aged 60 years or older were evaluated. The secondary, non-prosthetic fracture related treatments during the 8 year follow-up period were registered. Main outcome measuresOf the prognostic factors, age, gender, type of fracture, season and day of the primary surgery, length of waiting time to the operation and the accompanied diseases were evaluated as risk factors for all type of fracture-related further interventions, with the exception of arthroplasties. ResultsA total of 2895 patients with intracapsular femoral neck fractures met the study criteria. The mean age was 77.96 years (SD: 8.54). The cohort of the patients was observed for a total of 10,077.8 person-years. The non-prosthetic fracture related treatment was performed in 265 patients (9,2%); the median of the time elapsed to the secondary definitive treatment was 3.5 months. With Cox regression analysis, significant correlation was revealed between the incidence of non-prosthetic treatment and younger age (year, HR = 0.977, p = 0.002), surgical delay (12–24 h vs 0–6 h, HR = 1.518, p = 0.023; 24h+ vs 0–6 h, HR = 1.372, p = 0.050), season of primary osteosynthesis (fall vs summer, HR = 0.636, p = 0.012), and type of femoral neck fracture (intracapsular displaced vs intracapsular undisplaced, HR = 1.340, p = 0,047). There was no significant effect of the day of primary surgery, the gender and the presence of co-morbidities on the incidence of further surgical interventions. ConclusionThe summertime primary surgical intervention, delay of surgery longer than 12 h and type of femoral neck fracture are independent predictors of non-prosthetic further treatment of femoral neck fractures in elderly patients. Level of evidenceLevel IV, evidence from cohort studies.

Bone Loss Following Cementless Hemiarthroplasty for the Treatment of Femoral Neck Fracture.

With the advances in medicine, an increasing number of the ageing population are a public health concern in terms of age-related complications. Among them, displaced neck fractures often require surgical intervention or arthroplasty to achieve the mobilization of the elderly and good life quality. The aim of the study is to monitor the changes in bone mineral density (BMD) around the femoral stem and the effects on functional outcomes in patients treated with cementless hemiarthroplasty following femoral neck fracture. Seventy-one patients aged 70years or older who were treated with cementless hemiarthroplasty for a displaced femoral neck fracture were prospectively followed for 2years. The percent change in the periprosthetic BMD in each Gruen zone was compared to the baseline using dual-energy X-ray absorptiometry (DEXA). Demographic factors [age, body mass index (BMI), and sex] that could possibly influence BMD and the clinical outcome were evaluated. Fifty-one patients were available for the final follow-up. The mean age was 76.5 (range 70-89) years. The mean BMI was 28.9 (range 22.7-37.2). The mean Harris hip score at the final follow-up was 84.3 (range 72-93). There was a significant decrease in BMD in all Gruen zones (p < 0.001), except in zone 3 (R3, p = 0.547). The reduction in BMD was highest in the calcar and the greater trochanter region. The femur diaphysis was relatively spared, with zone 3 showing no significant bone mineral loss. The age and BMI of the patients were not correlated with the postoperative change in BMD in any of the Gruen zones. The degree of reduction in bone density was not correlated with the clinical outcome. Cementless hemiarthroplasty for the treatment of femoral neck fracture in elderly patients achieves a good clinical outcome despite significant bone loss around the femoral stem. The reduction in BMD is more pronounced in the metaphyseal region.

Development of a Nomogram for Predicting Blood Transfusion Risk After Hemiarthroplasty for Femoral Neck Fractures in Elderly Patients.

BackgroundThe aim of this study was to determine the risk factors and develop a nomogram for blood transfusions after hemiarthroplasty (HA) in patients with femoral neck fractures (FNFs).Material/MethodsWe performed a retrospective study including consecutive elderly FNF patients treated by HA between January 2015 and December 2017. Perioperative information was obtained retrospectively, uni- and multivariate regression analyses were conducted to determine risk factors for blood transfusion, and a nomogram model was constructed to predict the risk of blood transfusion. The predictive performance and consistency of the model were evaluated by the consistency coefficient (C-index) and the calibration curve, respectively.ResultsOf 178 patients, 151 were finally enrolled in the study and 21 received blood transfusion. Binary logistic regression analysis showed the low preoperative hemoglobin (Hb), longer time to surgery, general anesthesia, longer surgery duration, and higher intraoperative blood loss (IBL) were risk factors for blood transfusion. The accuracy of the contour map for predicting transfusion risk was 0.940.ConclusionsWe found a correlation between blood transfusion requirement and low preoperative Hb, longer time to surgery, general anesthesia, longer surgery duration, and higher IBL, and we then developed a nomogram. Our nomogram model can be used to evaluate the transfusion risk for FNF patients after HA, and provides better guidance for clinicians to intervene perioperatively, so as to reduce the incidence of blood transfusion.

Incidence and related factors of hypoxia associated with elderly femoral neck fractures in the emergency department setting.

Femoral neck fractures in elderly patients needing oxygen therapy are often encountered in the emergency department. This single-center, retrospective, observational study aimed to examine the frequency, cause, and factors related to hypoxia in elderly patients with femoral neck fractures. We analyzed data from 241 patients admitted to Okayama Saiseikai General Hospital (Okayama, Japan) from April 2016 to March 2019. Hypoxia was defined as PaO2/FiO2 ratio under 300. The independent factors for hypoxia were determined by multiple logistic regression analysis. There were 194 patients who met the study inclusion criteria, 148 in the non-hypoxia group and 46 in the hypoxia group. The hypoxia group included patients with pneumonia (n=3), chronic obstructive pulmonary disease (n=2), pulmonary edema (n=1), and pulmonary embolization (n=1). The cause of hypoxia was undetermined in 39 cases. However, occult fat embolism syndrome was suspected in 29 of these 39 cases based on Gurd and Wilson criteria after considering clinical examination results. Barthel indexes were significantly lower in the hypoxia group on discharge. Age (adjusted odds ratio [OR] 1.07; 95% confidence interval [CI], 1.00-1.14; P=0.038), D-dimer (adjusted OR 1.02; 95% CI, 1.00-1.03; P=0.005), and transtricuspid pressure gradient (adjusted OR 1.03; 95% CI, 1.00-1.07; P=0.015) were independently associated with the hypoxia. We found that hypoxia, including undetermined hypoxia, was commonly encountered in the emergency department. Hypoxia in elderly patients with femoral neck fractures was associated with age, D-dimer, and transtricuspid pressure gradient and needs further investigation.

Post-operative ischaemic stroke after transpulmonary embolism: A diagnostic challenge

Fixing a femoral neck fracture in elderly patients restores their independent mobility, and decreases the associated mortality and morbidity. Perioperative stroke is the most undesired complication in such patients, having a miserable outcome. We report a similar case where the patient developed ischaemic stroke in the immediate post-operative period, where a diagnostic workup revealed the presence of a new-onset pulmonary arterial hypertension with suspected embolism, in the absence of cardiopulmonary shunt, visible thrombus or embolus of cardiac origin. This case highlights the diagnostic dilemma in evaluating the cause of post-operative stroke and emphasises the need for a multimodal approach to investigate the suspected acute pulmonary embolism and to identify the possible sites for the origin of an embolus.

The optimal approach in hip hemiarthroplasty: a cohort of 1009 patients.

A hip hemiarthroplasty is the treatment of choice for a displaced femoral neck fracture in elderly patients not eligible for total hip arthroplasty. There is continuing debate about the optimal surgical approach for this operation, with the most commonly used approaches being posterior and lateral. To compare the outcomes of the posterior and the lateral approaches in patients with a displaced femoral neck fracture treated by hemiarthroplasty. A retrospective study was carried out in two high-volume teaching hospitals in the Netherlands. Electronic patient records were searched for patient characteristics, the operative approach and adverse outcomes. A total of 1009 patients with a median age of 86years were included. The posterior approach was used in 51.1% of patients. There were no differences in surgical site infection and periprosthetic fracture rates. There was a trend towards more dislocations in the posterior approach (2.9% vs. 1.4% with an OR of 2.1, 95% CI 0.8-5.1). An uncemented hemiprosthesis was used in 62.7% of patients. Deep surgical site infections and periprosthetic fractures occurred more often in the uncemented group (OR 2.9 and 7.4, respectively). No differences in adverse outcomes between both approaches could be shown. This study did confirm the relatively high incidence of post-operative complications in uncemented prostheses. Therefore, the cemented prosthesis should be the treatment of choice, with the approach dependent on surgeon preference and experience.

In the comparative study of Harris Hip score degrees in both methods were quite functional, chi-square test was 3.90 DF=3, and p&amp;gt;0.05.&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Conclusions:&lt;/strong&gt; This study of bipolar hemiartho pasty with cement or without cement will be quite effective to treat the neck fracture in old patients due to its dual fixation because calcar femorale present in the neck of the femur become function less with advancement of age moreover neck of the femur is devoid of periosteum Hence healing of neck fracture of the femur is medical challenge.&lt;/p&gt;&lt;p align="center"&gt; &lt;/p&gt;

Impact of Renal Function on the Surgical Outcomes of Displaced Femoral Neck Fracture in Elderly Patients.

Background: The aim of this study was to investigate the relationship between estimated glomerular filtration rate (eGFR) and outcomes of bipolar hemiarthroplasty for femoral neck fracture in elderly patients, and to compare postoperative complications and mortality among groups according to eGFR. Methods: A total of 181 patients who underwent bipolar hemiarthroplasty for displaced femoral neck fracture were divided into three groups according to eGFR. Data were retrospectively analyzed. Group 1 had 96 patients with eGFR greater than or equal to 60 mL/min/1.73 m2; Group 2 had 54 patients with eGFR greater than or equal to 30 mL/min/1.73 m2 and lower than 60 mL/min/1.73 m2; and Group 3 had 31 patients with eGFR lower than 30 mL/min/1.73 m2. Postoperative complications and mortality were compared between groups at a minimum 2-year follow-up. Results: Patients in Group 3 had the longest hospital stay of the three groups (p = 0.001). The rates of medical complications did not differ significantly among groups. However, Group 2 and 3 had higher rates of surgical complications (p = 0.001) and mortality (p = 0.043) than Group 1. Severe renal impairment was associated with increased risk of postoperative complications compared to mild renal impairment (odds ratio (95% confidence interval) = 4.33 (1.32–13.19), p = 0.015). Conclusion: Patients with moderate or severe decreased eGFR associated with chronic kidney disease (CKD) could have higher postoperative complications and mortality after bipolar hemiarthroplasty compared to patients with CKD stage 1 or 2.

Internal fixation of intracapsular femoral neck fractures in elderly patients: mortality and reoperation rate.

A significant increase in the prevalence of intracapsular femoral neck fractures in the elderly population was reported but the best treatment is still debated. To evaluate the mortality rate and the reoperation rate of stable neck fractures treated with cannulated screw fixation in elderly patients. This was a retrospective study of patients older than 60years with a Garden I or II femoral neck fractures treated with cannulated screw fixation without capsulotomy. A total of 244 patients (246 hips) who underwent surgery between 2008 and 2018 were included. The average age at the time of surgery was 80years (range 60-99years). The mean ASA score was 2.64 (range 1-4). Mortality rate, complications, reoperation rate, the time elapsed between surgeries were recorded. The mortality rate was 50.0%. There were 16 mortalities (6.6%) in the first-month follow-up. We observed higher mortality rates in ASA 4 (80.8%). In 22 patients (8.9%), complications after surgery were observed, and in 11 patients (4.5%) underwent conversion surgery to hemiarthroplasty at a mean of 14.6months (range 2-48months) after the femoral screw fixation. Two patients were treated with hardware removal and Gamma Nail for a peri-implant subtrochanteric femur fracture. Cannulated screw fixation should be considered a valid option in intraarticular femoral Garden I-II fractures in elderly patients. Level IV, therapeutic study.
