Mechanism Failures in Externally Controlled Motorized Intramedullary Lengthening Nails: A Systematic Review.

Puntos clave

• To evaluate the various mechanism failures associated with motorized intramedullary lengthening nails and their implications for clinical practice.
• Conducted systematic review of existing literature on mechanism failures in motorized intramedullary nails.
• Analyzed technical flaws, material weaknesses, and biomechanical impacts of nail design.
• Reviewed case reports and clinical studies to compile data on failure rates and types.
• Identified common failure mechanisms including mechanical and design-related issues.
• Noted a significant incidence of complications linked to specific nail designs.
• Highlighted the need for better design and preclinical testing to reduce failures.
