Aims. Our primary aim was to assess reoperation-free survival at one year after the index injury in patients aged ≥ 75 years treated with internal fixation (IF) or arthroplasty for undisplaced femoral neck fractures (uFNFs). Secondary outcomes were reoperations and mortality analyzed separately. Methods. We retrieved data on all patients aged ≥ 75 years with an uFNF registered in the Swedish Fracture Register from 2011 to 2018. The database was linked to the Swedish Arthroplasty Register and the National Patient Register to obtain information on comorbidity, mortality, and reoperations. Our primary outcome, reoperation, or death at one year was analyzed using restricted mean survival time, which gives the mean time to either event for each group separately. Results. Overall, 3,909 patients presenting with uFNFs were included. Of these patients, 3,604 were treated with IF and 305 with primary arthroplasty. There were no relevant differences in age, sex, or comorbidities between groups. In the IF group 58% received cannulated screws and 39% hook pins. In the arthroplasty group 81% were treated with hemiarthroplasty and 19% with total hip arthroplasty. At one year, 32% were dead or had been reoperated in both groups. The reoperation-free survival time over one year of follow-up was 288 days (95% confidence interval (CI) 284 to 292) in the IF group and 279 days (95% CI 264 to 295) in the arthroplasty group, with p = 0.305 for the difference. Mortality was 26% in the IF group and 31% in the arthroplasty group at one year. Reoperation rates were 7.1% in the IF group and 2.3% in the arthroplasty group. Conclusion. In older patients with a uFNF, reoperation-free survival at one year seems similar, regardless of whether IF or arthroplasty is the primary surgery. However, this comparison depends on the choice of follow-up time in that reoperations were more common after IF. In contrast, we found more early deaths after arthroplasty. Our study calls for a randomized trial comparing these two methods. Cite this article: Bone Jt Open 2024;5(2):86–92

Introduction. Undisplaced femoral neck fractures have been given little attention in the literature. By using data from the Norwegian Hip Fracture Register, this study investigates risk for reoperation and the clinical results, including pain, patient satisfaction, and quality of life, after undisplaced femoral neck fractures in elderly patients. Material and Methods. Data on 4,468 patients over 70 years of age with undisplaced femoral neck fractures operated with internal fixation (IF) were compared to 10,289 patients with displaced femoral neck fractures treated with IF (n = 3,389) or bipolar hemiarthroplasty (n = 6,900). The evaluation was based on number of reported reoperations and patients' assessment (visual analogue scales concerning pain (0–100) and patient satisfaction (0–100), and quality of life (EQ-5D)) four and twelve months postoperatively. The patients were followed for 0–1 year. The Cox multiple regression model was used to construct adjusted survival curves. Subanalyses were performed on undisplaced femoral neck fractures to investigate different risk factors for reoperation. Results. The survival rate of implants after one year was 89% after screw fixation for undisplaced fractures, 79% after screw fixation for displaced fractures, and 97% after hemiarthroplasty for displaced fractures (Kaplan Meier). Adjusted for age, sex, ASA-classification, and cognitive function the displaced fractures operated with internal fixation had higher risk of reoperation compared to the undisplaced fractures operated with internal fixation (RR 1.92, 95% CI: 1.69–2.17; p<0.001). The displaced fractures operated with hemiarthroplasty had a lower risk of reoperation compared to the undisplaced fractures (RR 0.32, 95%CI: 0.27–0.38; p<0.001). Patients treated with IF for undisplaced fractures were more satisfied, had less pain, and higher quality of life compared to patients treated with IF after displaced fractures (p<0.05). The patients treated with bipolar hemiarthroplasty for displaced fractures had, however, the least pain, were most satisfied, and reported the highest quality of life. Discussion and Conclusion. The clinical outcome after undisplaced femoral neck fractures treated with screw fixation was better than the results of screw fixation for displaced fractures, but poorer than the clinical results for patients with displaced femoral neck fractures operated with a bipolar hemiarthroplasty. However, the differences in clinical outcome were smaller than what is considered to be of clinical importance. One year postoperatively screw osteosynthesis of undisplaced femoral neck fractures in elderly patients still seems to be a good alternative

The treatment of undisplaced femoral neck fracture in the elderly population is still controversial. We analysed the outcome of cancellous screw fixation for undisplaced femoral neck fracture in patients over 70 years. Materials and methods. From 1998 to 2003, ninety-seven patients with undisplaced femoral neck fracture, aged over 70 and treated with cancellous screw fixation were retrospectively identified. Full clinical data was available for 79 of the 97 patients identified. All patients had in situ fracture fixation. Results. Of the 79 patients, M:F was 22:57, average age was 81.3 years. The average inpatient stay was 13.2 days. The mean follow-up was 12 months. 24 patients had Garden type I and 55 type II fractures. 26 (32.9%) patients did not return to their pre-morbid mobility status, 5 (6.3%) did not return to their preadmission dwelling (2 went to residential homes and 3 to nursing homes). We had documented radiographic details in 46 patients: 41 patients had a healed fracture on radiographs (89.1%), 5 patients had AVN, 4 patients had non-union and 1 patient had AVN with non-union. The radiographic failure rate was 22%. 15 patients had evidence of screw back out with healed fracture. 12 of the 46 complained of pain post-operatively of which 9 (19.6%) patients had re-operation; 6 (13%) underwent revision surgery and 3 (6.5%) required screw removal. 30-day mortality was 3.7%. 1-year mortality was 23.2% of which 16 died within the first 6 months (19.5%). Conclusion. This study shows that, in our unit, cancellous screw fixation of undisplaced femoral neck fractures in patients over the age 70 had a good outcome with a 20% re-operation rate and 22% radiographic failure rate. One third of the patients did not return to their preadmission mobility level/dwelling

A femoral fracture in an adolescent is a significant injury. It is generally agreed that operative fixation is the treatment of choice and rigid intramedullary nailing is a surgical treatment option. We present on experience of treating adolescent femoral fractures using a lateral entry intramedullary nail. We reviewed 15 femoral fractures in 13 children who we treated in our unit between 2011 and 2014. Two patients had bilateral fractures (non-simultaneous). Data collected included patient demographics, mechanism of injury, type of fracture, associated injuries, size of nail, time to unite and complications. The mean age of the patients at time of surgery was 12 years (range 10–15). There were 7 male and 6 female. 10 fractures were caused by a fall whilst 5 were due to road traffic collisions (RTC). 8 fractures involved the middle third, 2 of theses were open fractures and were caused by a RTC. The remaining 7 involved the proximal third of the femur. The mean time to radiological union was 3.4 months (range 2.5–5) in 14 fractures. One patient had a delayed union that required bone grafting and united fully at 7.5 months post injury. The only other complications were a broken proximal locking screw in one patient and an undisplaced femoral neck fracture in another patient. These complications did not compromise the outcome. No patients had infection or developed avascular necroses at the latest follow up. Intramedullary nailing of adolescent femoral fractures using the lateral entry point is safe and effective

Purpose: Femoral neck fracture collapse and shortening has been a desired effect of parallel screw fixation to promote healing. While some degree of compression might be beneficial, it remains unknown whether the effects of uncontrolled femoral neck shortening leads to detectable functional impairment. We aimed to evaluate the effect of shortening and varus collapse after cancellous screw fixation of femoral neck fractures on patient functional status and quality of life. Method: The databases of four University Hospitals were screened to identify patients with a healed isolated femoral neck fracture. Patients were contacted by telephone to complete Short-form 36(SF36) and Euroquol-5D(EQ5D) questionnaires (Primary outcome: SF36 physical functioning score[PF]). Femoral neck shortening and varus collapse were assessed by three independent reviewers blinded to functional outcome results based on the latest follow-up radiographs and categorized into three grades: None/Mild (within 5mm/5°), Moderate (5–10mm/5–10°), and Severe (> 10mm/> 10°). The minimal clinically important difference for SF36 PF score equals 12 points (1/2 of Standard deviation). Results: Out of 660 patients screened at all four sites 70 met the inclusion criteria and were available for follow-up. The average follow-up was 20 months and an the average age was 71 years. Overall, there were 24/70 patients with none/mild femoral neck shortening, 25/70 with moderate shortening and 21/70 with severe shortening. Patients with severe shortening of their hip had significantly lower SF36 physical functioning scores (No/Mild vs. Severe shortening: 74 vs. 42 points, p=0.01). Similar important effects occurred with moderate shortening suggesting a gradient effect (No/Mild vs. Moderate shortening: 74 vs. 53 points). Some degree of varus collapse occurred in 39% of the patients and correlated moderately with the occurrence of shortening (r=0.66, p< 0.001). Conclusion: A large proportion of displaced and undisplaced femoral neck fractures fixed with cancellous screws heal in a shortened position (66%) and varus (39%). The differences in function we observed represent patient important declines and suggest that uncontrolled sliding with cancellous screw fixation has limitations

Aims

While interdisciplinary protocols and expedited surgical treatment improve the management of hip fractures in the elderly, the impact of such interventions on patients specifically undergoing arthroplasty for a femoral neck fracture is not clear. We sought to evaluate the efficacy of an interdisciplinary protocol for the management of patients with a femoral neck fracture who are treated with an arthroplasty.

Aims

This study aimed to describe preoperative waiting times for surgery in hip fracture patients in Norway, and analyze factors affecting waiting time and potential negative consequences of prolonged waiting time.

Aims

The aim of this study was to describe variation in hip fracture treatment in Norway expressed as adherence to international and national evidence-based treatment guidelines, to study factors influencing deviation from guidelines, and to analyze consequences of non-adherence.

Objectives

Fractures of the proximal femur are a common clinical problem, and a number of orthopaedic devices are available for the treatment of such fractures. The objective of this study was to assess the rotational stability, a common failure predictor, of three different rotational control design philosophies: a screw, a helical blade and a deployable crucifix.

The December 2014 Trauma Roundup³⁶⁰ looks at: infection and temporising external fixation; Vitamin C in distal radial fractures; DRAFFT: Cheap and cheerful Kirschner wires win out; femoral neck fractures not as stable as they might be; displaced sacral fractures give high morbidity and mortality; sanders and calcaneal fractures: a 20-year experience; bleeding and pelvic fractures; optimising timing for acetabular fractures; and tibial plateau fractures.

The best treatment for the active and lucid elderly patient with a displaced intracapsular fracture of the femoral neck is still controversial. Randomised controlled trials have shown that a primary total hip replacement is superior to internal fixation as regards the need for secondary surgery, hip function and health-related quality of life. Despite good results achieved with total hip replacement in this group, most orthopaedic surgeons still advocate hemiarthroplasty for this injury. We studied 120 patients with a mean age of 81 years (70 to 90) with an acute displaced intracapsular fracture of the femoral neck. They were randomly allocated to be treated with either a bipolar hemiarthroplasty or total hip replacement. Outcome measurements included peri-operative data, general and hip-specific complications, hip function and health-related quality of life. The patients were reviewed at four and 12 months.

The duration of surgery was longer in the total hip replacement group (102 minutes (70 to 151)) versus 78 minutes (43 to 131) (p < 0.001), and the intra-operative blood loss was increased 460 ml (100 to 1100) versus 320 ml (50 to 850) (p < 0.001), but there were no differences between the groups regarding any complications or mortality. There were no dislocations in either group. Hip function measured by the Harris hip score was significantly better in the total hip replacement group at both follow-up periods (p = 0.011 and p < 0.001, respectively). The health-related quality of life measure was in favour of the total hip replacement group but did not reach statistical significance (p = 0.818 at four months and p = 0.636 at 12 months).

These results indicate that a total hip replacement provides better function than a bipolar hemiarthroplasty as soon as one year post-operatively, without increasing the complication rate. We recommend total hip replacement as the primary treatment for this group of patients.

The incidence and long-term outcome of undisplaced fatigue fractures of the femoral neck treated conservatively were examined in Finnish military conscripts between 1970 and 1990.

From 106 cases identified, 66 patients with 70 fractures were followed for a mean of 18.3 years (11 to 32). The original medical records and radiographs were studied and physical and radiological follow-up data analysed for evidence of risk factors for this injury. The development of avascular necrosis and osteoarthritis was determined from the follow-up radiographs and MR scans.

The impact of new military instructions on the management of hip-related pain was assessed following their introduction in 1986. The preventive regimen (1986) improved awareness and increased the detected incidence from 13.2 per 100 000 service-years (1970 to 1986) to 53.2 per 100 000 (1987 to 1990). No patient developed displacement of the fracture or avascular necrosis of the femoral head, or suffered from adverse complications. No differences were found in MRI-measured hip joint spaces at final follow-up. The mean Harris Hip Score was 97 (70 to 100) and the Visual Analogue Scale 5.85 mm (0 to 44).

Non-operative treatment, including avoidance of or reduced weight-bearing, gave favourable short- and long-term outcomes. Undisplaced fatigue fractures of the femoral neck neither predispose to avascular necrosis nor the subsequent development of osteoarthritis of the hip.
