Open Reduction and Internal Fixation of Hoffa Fracture with Plate and Screws

1. Principles General ConsiderationsHoffa fractures involve the critical weight-bearing surface of the knee joint and require anatomical reduction and absolute stability of fixation. In general, a buttress plate with lag screws is recommended. Howev...

Minimally Invasive K‑Wire and Screw Fixation for Calcaneal Fractures

1. Diagnosis Example image: CT shows a displaced fracture of the posterior facet as a single fragment, amenable to minimally invasive elevation and fixation with a subchondral lag screw. 2. Surgical Approach Either the sinus tarsi approach or ...

Characteristics and Surgical Techniques of the "Double‑Intra" Type of Irreducible Intertrochanteric Fractures

Intertrochanteric fractures are one of the three major osteoporotic fractures, with high incidence, high disability rates, and high rates of internal fixation failure. Closed reduction and intramedullary nailing is currently the first‑line treatment ...

Retrograde Intramedullary Nailing for Periprosthetic Femoral Fractures After TKA: AO Standardized Surgical Strategy – Illustrated Step-by-Step Guide

1. Illustration Legend All images in this procedure are generic fracture classification schematics, divided into four categories:A) Fracture unreducedB) Fracture reducedC) Fracture reduced and temporarily stabilizedD) Final definitive fixation 2. S...

How to Correctly Create the Entry Point During Surgery for Intertrochanteric Fractures

First, a small incision of approximately 2–3 cm is made just proximal to the greater trochanter to establish a proper soft‑tissue corridor. For elderly patients with poor bone quality, to reduce surgical time, a direct entry technique can be em...

Changes in Entry Point for Intramedullary Nailing of Proximal Femoral Fractures: The Central Collinear Method

The reconstruction nail is an effective treatment option for proximal femoral fractures and is currently widely used in clinical practice. Common entry points include the piriformis fossa and the trochanteric fossa, each with its own advantages and d...

Proximal Femoral Fractures: Classification-Guided Treatment

Introduction Numerous classification systems (over a dozen) exist for proximal femoral fractures. Most are based on two‑dimensional X‑ray images and focus primarily on medial wall support, while insufficient attention has been paid to the integrity ...

Subtrochanteric Femur Fractures: Anatomy, Classification, and Treatment Options

Subtrochanteric (ST) femur fractures are defined as fractures occurring within 5 cm distal to the lesser trochanter. Overall, the estimated incidence of these fractures is approximately 15–20 per 100,000 people per year. The age distribution s...

Open Reduction and Internal Fixation with Plate for Hoffa Fracture

 I. Principles General ConsiderationsHoffa fractures involve critical weight-bearing areas of the knee joint and require anatomical reduction and absolute stability of fixation. Generally, a buttress plate combined with lag screws is recommended...

Antegrade Intramedullary Screw Fixation for Metacarpal Fractures: A Novel Technique

This article presents an intramedullary fixation method that preserves the articular cartilage of the metacarpal head, minimizes soft tissue disruption, and provides stable fixation by implanting antegrade intramedullary screws through the metacarpal...
