Summary
This case study details repeated fractures of a modular hip prosthesis in one patient over 17 years. It explores causes and revision strategies for fractured hip implants.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
Background:
- Total hip replacement is a common procedure.
- Modular hip prostheses offer surgical flexibility but may have unique failure modes.
Observation:
- A 56-year-old male patient experienced two fractures of his modular hip prosthesis over 17 years post-implantation.
- The fractures occurred in the prosthetic implant itself.
Findings:
- Repeated prosthetic fractures in modular hip implants are a rare but significant complication.
- Potential causes include material fatigue, surgical technique, and patient-specific factors.
Implications:
- Understanding the causes of modular hip prosthesis fractures is crucial for preventing future occurrences.
- Appropriate selection of revision techniques is vital for successful management of fractured hip implants.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:31Bone Remodeling and Repair
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
