[The value of dynamic adjustment in locking intramedullary nailing]

Area of Science:

• Orthopedic surgery
• Bone fracture fixation

Background:

• Static locking nail technique is a common method for femur and tibia fractures.
• Dynamization, involving bolt removal post-consolidation, is a theoretical step to promote bone remodeling.

Purpose of the Study:

• To evaluate the feasibility and indications of dynamization after static locking nail surgery.
• To assess the complication rates associated with dynamization.

Main Methods:

• Retrospective analysis of 121 patients treated with static locking nails.
• X-ray monitoring for osseous consolidation between 6-10 weeks post-surgery.
• Documentation of performed dynamization procedures and complications.

Main Results:

• Dynamization was only performed in 23 out of 121 patients (19%).
• Complications arose from incorrect or omitted dynamization indications.
• Individualized X-ray assessment is crucial for determining dynamization necessity.

Conclusions:

• Dynamization is not a routine procedure after static locking nail fixation.
• It is indicated in rare cases and requires careful, individualized patient assessment.
• Routine dynamization is discouraged due to potential complications.
