The Effect of Type of Femoral Component Fixation on Mortality and Morbidity after Hip Hemiarthroplasty: A Systematic Review and Meta-Analysis

Which factor is more associated with survival of patients with hip fracture over 90 years: Type of fracture or treatment modality?

OBJECTIVE

We aimed to analyze prognostic factors affecting the mortality and to evaluate whether the fracture type (collum femoris or intertrochanteric fracture) or treatment method (proximal femoral nail or hemiarthroplasty) affects the mortality in patients with hip fractures and older than 90 years old.

METHODS

In our study, we retrospectively reviewed the patients aged >90 years and operatively treated hip fractures. Patients were categorized according to fracture type and treatment method. Finally, three groups were created. Demographic values, laboratory values were analyzed for prognostic factors and determining independent factors associated with survival for each group.

RESULTS

A total of 193 patients were included with an average age of 92.5±2.4 (range, 90-104) years. There were 144 women and 49 men. There were 126 (65.2%) patients with intertrochanteric fracture and 67 (34.8%) patients with collum femoris fracture. At the time of this study, 142 (73.5%) patients had deceased. Staying in intensive care unit for collum femoris group, general anesthesia for intertrochanteric fracture treated with hemiarthroplasty group and delay to surgery and preoperative albumin level for intertrochanteric fracture treated with proximal femoral nail group were associated with poor survival.

CONCLUSION

Staying intensive care unit, general anesthesia, delay to surgery and preoperative albumin levels should be carefully evaluated for patients aged over 90 years with hip fractures. Our study showed that both fracture type and treatment modality were not associated with poor overall survival of the patients aged >90 years following hip fracture surgery.

Outcomes of Femoral Neck Fractures in Young Patients and the Factors Associated With Complications: A Multicenter Study From Malaysia

Background and objective Femoral neck fractures are relatively rare in young adults, but they result in prolonged loss of function in these patients, thereby placing a huge burden on a country's healthcare and economy. Femoral neck fractures in young adults are normally treated with head salvage surgery. However, primary head replacement surgeries have been gaining traction recently to expedite the recovery of these patients. In this study, we aimed to investigate the outcomes in young patients with femoral neck fractures and factors associated with their complications. Patients and methods Patients with femoral neck fractures who underwent surgery in three tertiary hospitals [Hospital Tengku Ampuan Afzan (HTAA), Hospital Sultan Haji Ahmad Shah (HOSHAS), and Hospital Kuala Lipis] in Pahang state in Malaysia were reviewed and included in this study. The demographic profile of the patients, injury patterns, intervention details, functional outcomes, and complications were analyzed. The comparison between the sociodemographics, clinical assessment, and complication outcomes was analyzed using statistical software. Results The complications were associated with the mechanism of injury, capsulotomy, and type of fixation. A total of 46 patients were included in the study. Most of the patients were found to have severe displacement based on Garden and Pauwels classification. The majority of the patients underwent femoral head salvage surgeries. Almost half of the patients sustained complications and were unable to achieve weight-bearing status at six months postoperatively. Conclusion Despite a relatively short follow-up period in our study, femoral neck fractures in young adults were found to be associated with a high rate of complications. Primary head replacement surgeries should be considered in high-risk patients with femoral neck fractures.

Use of a Plasma-Sprayed Titanium-Hydroxyapatite Femoral Stem in Hip Arthroplasty in Patients Older than 70 Years. Is Cementless Fixation a Reliable Option in the Elderly?

Background: Although cementless implants are increasing in popularity, the use of cementless femoral stems for total hip arthroplasty (THA) and hip hemiarthroplasty (HH) in elderly patients remains controversial. The aim of this study was to report the outcomes of a cementless stem used in a large multicentric cohort of elderly patients receiving elective THA and HH for displaced femoral neck fracture. Methods: A total of 293 patients (301 hips) aged 70 years or older (mean age, 78 years; range, 70–93) who received the same cementless plasma-sprayed porous titanium–hydroxyapatite stem were retrospectively evaluated after primary THA and HH to investigate stem survival, complications, and clinical and radiographic results. Results: Cumulative stem survival was 98.5% (95% CI, 96.4–99.4%; 91 hips at risks) with revision due to any reason as the end-point at 10-year follow-up (mean 8.6 years, range 4–12). No stem was revised due to aseptic loosening. The mean Forgotten Joint Score was 98.7. Radiographically, the implants showed complete osseointegration, with slight stress-shieling signs in less than 10% of the hips. Conclusion: The use of cementless stems was proven to be a reliable and versatile option even in elderly patients for elective THA and HH for femoral neck fracture.
