Ulnar shaft fractures, even with minimal displacement, can directly compromise pronation and supination when managed inadequately. This training objectively demonstrates osteosynthesis with a plate on the tension cortex, with emphasis on tissue preservation and interfragmentary compression, presented in 4K video under a surgical perspective.

TRAINING FOCUS

• Osteosynthesis of ulnar shaft fracture with plate.
• Approach between the extensor carpi ulnaris and flexor carpi ulnaris.
• Periosteal preservation and muscle-sparing approach.
• Compression technique with pre-tensioned plate.
• Anatomical reduction using different instrumental strategies.

DETAILED CONTENT

• Precise Intermuscular Approach: Identification and safe dissection of the plane between ECU and FCU, preserving muscular integrity.
• Biological Preservation of the Fracture Site: Controlled opening of the periosteum with a scalpel, maintaining vascularization and favoring consolidation.
• Controlled Anatomical Reduction: Progressive use of instruments (including alternatives such as Kelly forceps) for safe reduction.
• Implantation on the Tension Cortex: Correct positioning of the plate on the dorsal cortex of the ulna for biomechanical optimization.
• Plate Pre-tensioning: Practical application of tensioning to generate effective compression at the fracture site.
• Interfragmentary Compression Technique: Use of an eccentric screw in an oval hole for primary stability.
• Rational Fixation Sequence: Screw insertion strategy for progressive control of reduction.
• Soft Tissue Protection: Layered closure with reconstruction of the periosteum and fascia, reducing impact on tissues.
• Intraoperative Functional Validation: Immediate assessment of pronation and supination after fixation.
