AI Article Synopsis
- Chondroblastomas are rare, benign tumors often found in the bones of younger patients, typically treated through curettage and bone fillers.
- A case study details a 19-year-old woman who experienced a hip fracture due to an underlying chondroblastoma, leading to a surgical procedure including open biopsy, cryotherapy, and stabilization of the fracture.
- The final diagnosis confirmed the presence of a chondroblastoma, highlighting the need for clinicians to consider such rare lesions in young patients presenting with femoral neck fractures.
Article Abstract
Chondroblastomas usually present in the epiphyseal region of bones in skeletally immature patients. These uncommon, benign tumors are usually treated with curettage and use of a bone-void filler. Here we report a case of a hip fracture secondary to an underlying chondroblastoma in a 19-year-old woman. Open biopsy with intraoperative frozen section pointed toward a diagnosis of chondroblastoma. Extended curettage was performed, followed by cryotherapy with a liquid nitrogen gun and filling of the defect with calcium phosphate bone substitute. The femoral neck fracture was stabilized with a sliding hip screw construct. The patient progressed well and continued to regain functional status. A final pathology report confirmed the lesion to be a chondroblastoma. Clinicians should have heightened awareness of a pathologic lesion in a young person presenting with a femoral neck fracture and should consider the uncommon differential diagnosis that the lesion is located in the greater trochanter apophysis.

Background: Osteoporosis is characteristically defined as a decrease in bone density and mass, accompanied by the deterioration of bone structure, which increases bone fragility and the risk of fractures. Osteoporosis frequently develops with age. In high-risk populations, oxidative damage is a common pathological condition.

In this study, specimens from patients undergoing total hip arthroplasty (THA) were analyzed. The results revealed significantly higher Visual Analog Scale (VAS) scores and CT low-density area ratio in the BME group compared to the control group.

Objective: Previous observational studies on the association between aspirin use, bone mineral density (BMD), and fracture risk have yielded controversial results. This study explored the causal relationship between aspirin use, BMD, and fracture risk using Mendelian randomization (MR).
Methods: Summary data for aspirin use and BMD of five different body parts (femoral neck, lumbar spine, forearm, heel, and ultra distal forearm) and fractures were obtained from the integrative epidemiology unit open genome-wide association studies database for bidirectional MR analysis.

Introduction: A primary objective when performing a total hip arthroplasty (THA) is to restore hip biomechanics in accordance with a chosen surgical plan. The aim of this study was to assess the accuracy of a 3D-printed patient-specific guide for delivering a planned femoral osteotomy for both a posterior and an anterior approach.
Methodology: 40 patients (20 anterior and 20 posterior) scheduled for THA received a preoperative work-up allowing for patient-specific implant sizing and positioning.

Proximal femoral fractures (PFFs) among individuals aged ≥90 years are becoming more common with an aging population and are associated with high morbidity and mortality. This study analyzed the prognostic factors influencing survival in nonagenarian patients undergoing surgery for PFFs. We enrolled 285 patients who underwent surgery between 2016 and 2022.
