Low Profile, High Impact: External Fixation using Locking Plates in Challenging Tibial Fractures

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Biomaterials Engineering

Background:

• Metadiaphyseal tibial fractures with compromised soft tissues present significant surgical challenges.
• Traditional external fixators are common, but locking compression plates (LCPs) used externally offer a low-profile, angularly stable alternative.

Purpose of the Study:

• To evaluate the clinical outcomes of using locking plate external fixators (LPEFs) for metadiaphyseal tibia fractures.
• Assess union rates, complication profiles, and functional recovery in patients treated with LPEFs.

Main Methods:

• A prospective study of 15 adult patients with open or soft-tissue-compromised metadiaphyseal tibia fractures.
• Treatment involved applying LCPs as external fixators over 12 months.
• Outcomes measured included radiological union, time to weight-bearing, infection and reoperation rates, and functional scores (KSS, AOFAS).

Main Results:

• A 90% union rate was achieved, with a mean time to union of 12.1 weeks.
• Complications were low, including one superficial infection (6.6%) and one reoperation (6.6%).
• Excellent functional outcomes were observed, with mean Knee Society Score (KSS) of 85 and American Orthopaedic Foot and Ankle Society (AOFAS) score of 81.

Conclusions:

• LPEF is a viable fixation method for complex tibial fractures involving soft-tissue compromise.
• This approach facilitates early mobilization and leads to fewer complications and superior functional results.
• Further research with larger cohorts is recommended to support broader clinical adoption.
