Fractures around Trochanteric Nails: The "Vergilius Classification System"

Area of Science:

• Orthopaedic Surgery
• Trauma Management

Background:

• Perinail fractures (PNFs) around trochanteric nails present significant challenges in orthopaedic surgery.
• Current treatment strategies often rely on general periprosthetic fracture guidelines, highlighting a knowledge gap specific to PNFs.

Purpose of the Study:

• To address the knowledge gap concerning PNFs.
• To propose a novel classification system for PNFs to aid orthopaedic surgeons in management.

Main Methods:

• A comprehensive literature review on PNFs was conducted.
• A panel of experts developed a classification system through a consensus meeting.
• The classification considers fracture localization, morphology, fragmentation, and healing status.

Main Results:

• A classification system with an alphanumeric code was proposed.
• This system can describe up to 54 distinct categories of PNFs using a 3- to 4-digit code.
• The classification incorporates key characteristics relevant to PNF treatment.

Conclusions:

• The proposed classification system offers a structured approach to PNFs.
• It aims to provide guidance for orthopaedic surgeons in managing these challenging fractures.
• This consensus-based system may improve patient outcomes through standardized treatment.
