Bisphosphonate therapy for osteoporosis may increase the risk of rare atypical subtrochanteric fractures. This case report highlights the need for increased clinical suspicion in patients on long-term bisphosphonate treatment.
Area of Science:
- Orthopedics
- Pharmacology
- Geriatrics
Background:
- Bisphosphonates are a cornerstone therapy for osteoporosis, effectively reducing fracture risk.
- Long-term bisphosphonate use is associated with potential adverse effects, including rare skeletal complications.
- Atypical subtrochanteric fractures are a growing concern in patients receiving bisphosphonate therapy.
Observation:
- This case report details patients experiencing non-traumatic or low-energy subtrochanteric fractures.
- These fracture patterns are atypical for the typical mechanisms of injury in osteoporotic patients.
- The patients in question were undergoing long-term bisphosphonate treatment.
Findings:
- A potential association exists between long-term bisphosphonate use and the occurrence of atypical subtrochanteric fractures.
- These fractures present with unusual characteristics and mechanisms of injury.
- The findings underscore a rare but significant side effect of bisphosphonate therapy.
Implications:
- Increased clinical awareness and suspicion for atypical subtrochanteric fractures in patients on bisphosphonates are warranted.
- This highlights the importance of balancing the benefits of bisphosphonate therapy against potential risks.
- Further research into the mechanisms and management of these fractures is crucial.

Fractures: Bone Repair
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...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
