The angle stable interlocking intramedullary nail (ASIN) is a new option for treating tibial plateau fractures (TPF). This study shows ASIN provides good fracture reduction and fixation with few complications.
Area of Science:
- Orthopedic Surgery
- Trauma Management
Background:
- Tibial plateau fractures (TPF) are complex injuries.
- The angle stable interlocking intramedullary nail (ASIN) is a novel technique for TPF management.
Purpose of the Study:
- To introduce the ASIN technique for TPF.
- To describe initial experiences and assess ASIN's effectiveness in TPF treatment.
Main Methods:
- Retrospective analysis of 19 closed TPF cases (2008-2013).
- All patients underwent the ASIN procedure.
- Radiographic, surgical, and clinical outcomes were evaluated using modified Hohl-Luck and HSS scores.
Main Results:
- Average follow-up of 26.3 months.
- All patients achieved bony union by 15.1 weeks; no malunion, nonunion, or infection.
- 16 patients had anatomical articular reduction; no fixation failure. Mean knee flexion was 122.9°.
- Excellent/good modified Hohl-Luck scores in 16 patients; mean HSS score was 89.4.
Conclusions:
- ASIN is a viable treatment for TPF.
- Satisfactory results include good fracture reduction, biomechanical fixation, low complication rates, and acceptable knee function.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
