Treating forearm fractures using an internal fixator: a prospective study

Area of Science:

• Orthopedic surgery
• Biomedical engineering
• Trauma care

Background:

• Internal fixation with plates can cause bone and soft tissue necrosis due to implant contact, leading to complications like infection and delayed healing.
• Minimizing implant-to-bone contact is crucial for preserving vascularity and promoting fracture healing.
• Existing internal fixation methods include nails, plates, and external fixators.

Purpose of the Study:

• To introduce and evaluate the Point Contact Fixator, a novel internal fixation device designed to minimize contact with the bone.
• To assess the safety and efficacy of the Point Contact Fixator in treating forearm fractures.

Main Methods:

• A prospective study was conducted on 79 forearm fractures in 55 patients.
• The Point Contact Fixator was used, featuring a splint fixed with monocortical, angularly locked screws designed for minimal implant-to-bone pressure.
• One surgeon applied the technique consistently throughout the study, with 100% patient follow-up to union.

Main Results:

• The Point Contact Fixator demonstrated simple handling and uneventful healing in the treated forearm fractures.
• The study reported a low rate of complications associated with the use of this new fixation device.
• Minimizing implant-to-bone contact successfully avoided vascular damage to the osseous blood supply.

Conclusions:

• The Point Contact Fixator represents a new class of internal fixation implants, offering a promising alternative to traditional plates.
• This innovative device effectively reduces complications by minimizing contact with the bone, thereby preserving blood supply.
• The prospective study confirms the safety and efficacy of the Point Contact Fixator for treating forearm fractures.
