Complex Limb Injuries: Limb Salvage Versus Amputation-A Mini Review and Meta-Analysis

Area of Science:

• Orthopedic Surgery
• Trauma Management
• Decision Science

Background:

• Complex limb injuries present significant management challenges, necessitating a choice between amputation and limb reconstruction.
• Effective care requires a multidisciplinary approach, starting with initial resuscitation and transfer to trauma centers for severe cases.

Purpose of the Study:

• To synthesize existing tools and resources aiding clinicians in decision-making for complex limb injuries.
• To provide a comprehensive overview of assessment, management strategies, and outcome considerations.

Main Methods:

• Review of literature on scoring systems (Mangled Extremity Severity Score, Narakawa Index, Musculoskeletal Score for Severity of Injury) for limb injury assessment.
• Analysis of factors influencing the choice between limb salvage and amputation, including clinical examination, imaging (CTA), and patient characteristics.

Main Results:

• Scoring systems like MESS, NISSSA, and MESI evaluate injury severity, neurovascular status, and patient factors to aid in limb salvage vs. amputation decisions.
• Damage Control Orthopedics principles are crucial for polytrauma patients, with prompt hemorrhage control and limb viability assessment via CTA being essential.

Conclusions:

• Effective management of complex limb injuries demands thorough assessment, multidisciplinary collaboration, and patient-centered care.
• Integrating medical expertise with patient preferences and expectations is crucial for optimizing long-term outcomes in limb salvage versus amputation decisions.
