Femoral neck fractures

Area of Science:

• Orthopedic surgery
• Geriatric medicine
• Biomaterials science

Background:

• Femoral neck fractures in elderly patients present significant therapeutic challenges.
• Surgical outcomes for these fractures, specifically nonunion and osteonecrosis rates, have seen minimal improvement over the past five decades.
• There is ongoing debate regarding the optimal treatment strategy, comparing internal fixation with various arthroplasty options.

Purpose of the Study:

• To review the current therapeutic challenges in managing geriatric femoral neck fractures.
• To discuss the comparative merits and complications of internal fixation versus arthroplasty (unipolar/bipolar hemiarthroplasty, total hip replacement).
• To explore potential future advancements in fracture prevention and treatment.

Main Methods:

• Literature review and synthesis of existing research on femoral neck fracture management in geriatric patients.
• Analysis of the historical and current outcomes associated with internal fixation and arthroplasty.
• Discussion of emerging trends in osteoporosis treatment and bone graft substitute technology.

Main Results:

• Despite advances, rates of nonunion and osteonecrosis after internal fixation have remained stagnant for 50 years.
• The comparative benefits and risks of unipolar hemiarthroplasty, bipolar hemiarthroplasty, and total hip replacement are not well-established.
• Internal fixation outcomes may be improved by future advances in bone graft substitutes.

Conclusions:

• Femoral neck fractures in the elderly continue to be a complex clinical problem with persistent challenges in surgical outcomes.
• Further research is needed to clarify the optimal surgical approach and understand the long-term implications of different arthroplasty types.
• Anticipated progress in osteoporosis management and bone regeneration holds promise for reducing fracture incidence and improving fixation success in the future.
