Summary
The novel lasso loop technique (LLT) effectively treats distal radius fractures with displaced bone fragments, significantly reducing the articular gap. This minimally invasive approach shows promising results with minimal complications.
Area of Science:
- Orthopedic surgery
- Biomaterials engineering
Background:
- Intra-articular distal radius fractures with displaced dorsal bone fragments (DBF) pose treatment challenges.
- Maintaining articular congruity is crucial for optimal functional outcomes.
Purpose of the Study:
- To introduce and evaluate the efficacy of the lasso loop technique (LLT) using a bioabsorbable thread for treating intra-articular distal radius fractures with DBF.
- To assess the reduction and maintenance of the articular gap, radiological parameters, and clinical outcomes following LLT.
Main Methods:
- Retrospective review of 19 patients who underwent LLT for intra-articular distal radius fractures with DBF.
- Analysis of radiographic images (CT and plain radiographs) and clinical data, including the Quick Disabilities of the Arm, Shoulder, and Hand (QDASH) scores.
Main Results:
- LLT significantly reduced the mean preoperative articular gap (2.6 mm) to <1.0 mm immediately postoperatively.
- No re-displacement of DBF was observed up to 6 months postoperatively.
- Satisfactory maintenance of palmar tilt, radial inclination, ulnar variance, joint range of motion, grip strength, and QDASH scores were achieved with no significant complications.
Conclusions:
- The lasso loop technique (LLT) provides a simple, effective, and safe method for reducing displaced dorsal bone fragments in intra-articular distal radius fractures.
- LLT demonstrates potential as a valuable treatment option for this specific fracture pattern, promoting good functional recovery.
