Polylactic acid bioabsorbable implants of the hand: A review

Area of Science:

• Orthopedic surgery
• Biomaterials science
• Hand surgery

Background:

• Metal implants are standard for hand fracture fixation, enabling early motion.
• However, retained metal hardware can cause stiffness, pain, and adhesions, often necessitating removal.
• Complications from metal implants can lead to secondary surgeries.

Purpose of the Study:

• To review biomechanical and clinical studies on bioabsorbable implants for hand fractures.
• To highlight the benefits of bioabsorbable materials over traditional metal implants.
• To advocate for the continued use and research of polylactic acid implants in hand orthopedics.

Main Methods:

• Literature review of biomechanical studies.
• Analysis of clinical trial data.
• Focus on polylactic acid-based bioabsorbable implants.

Main Results:

• Bioabsorbable implants demonstrate comparable fracture fixation to metal implants.
• They mitigate complications associated with retained hardware, such as pain and stiffness.
• Studies show successful bone union and functional recovery with bioabsorbable options.

Conclusions:

• Bioabsorbable implants, particularly those made of polylactic acid, are effective for hand fracture fixation.
• They offer a viable alternative to metal implants, reducing the risk of hardware-related complications.
• Further research and clinical adoption are encouraged to optimize their application in orthopedic hand injuries.
