Periprosthetic Bone Remodeling in Femoral Neck Fracture Patients; a 5-year Follow up Study

Periprosthetic Bone Remodeling in Femoral Neck Fracture Patients: a 5-year Follow up Study Addressing the Influence of Surgical Approach on Periprosthetic Bone Mineral Density.

Periprosthetic bone remodeling in femoral neck fracture patients: a 5-year follow up study addressing the influence of surgical approach on periprosthetic bone mineral density.

Between January 2014 and July 2017 a RCT was conducted at Sorlandet Hospital Kristiansand, Norway. The trial was approved by the regional ethics committee (2013/1853/REK) and registered at ClinicalTrials.gov (ClinicalTrials.gov Identifier NCT02028468).Patients between 70 and 90 years of age with displaced femoral neck fractures, intact cognitive function and the ability to walk with or without a walking aid prior to falling were asked for their agreement to be enrolled and partition occurred after informed consent.A subgroup analysis looking at periprosthetic bone mineral density around the femoral component was part of this level 1 single-center randomized trial. 51 patients were enrolled in this DEXA study, and future examination of bone remodeling in these patients is now planned.

Inclusion Criteria:

• Patients between 70 and 90 years of age with displaced femoral neck fractures
• Intact cognitive function
• Ability to walk with or without a walking aid prior to falling.

Exclusion Criteria:

• Dementia
• Fractures in pathologic bone
• Patients not belonging to the hospital community
• Patients with sepsis or local infection
• Fracture not eligible to be treated with a hemiarthroplasty
