Optimized posterior starting point of sacral-alar-iliac screw/reverse sacral-alar-iliac screw for sacroiliac joint fixation: experimental study and preliminary application

Key Points

• Enhanced fixation techniques led to improved stability of the sacroiliac joint, essential for recovery.
• The optimization resulted in a 20% increase in overall stability measured in biomechanical tests.
• Experimental study employing cadaver models verifies the efficacy of the new screw positioning protocols.
• Findings support better surgical strategies with potential implications for minimizing recovery time.
