Surgical operation and risk of complications of orthopedic surgical steel plates
Key points of surgical techniques
1. Steel plate length selection (span ratio>2-3), screw density control (recommended<0.5), screw sequence (ordinary screws first, then lock screws to apply pressure) 29.
2. Minimally invasive techniques (MIPO) require indirect reduction to avoid direct exposure of the fracture end.
Common complications
1. Loose/broken screws (angle deviation or stress concentration)
2. Fracture of bone plate (weak area of dynamic compression hole)
3. Infection
4. Reset lost 157
Identify the reasons for difficulties
1. Cold welding (adhesion caused by friction of titanium alloy material)
2. Screw slide wire
3. Scar wrapping or screw deformation
Living in Harmony with Your Circular External Fixator: A Patient's GuideWelcome to this guide! If you have recently undergone circular external fixation surgery, this material will help you understand how to live with this special "external companion" until your bones are fully healed.1. Getting to
Key Points of Ring External Fixation Operation and Care1. Purpose and Indications Ring external fixation involves passing steel pins through the bones and connecting them to an external circular frame to provide stable, adjustable three-dimensional fixation for fractures or deformities. It is mainl
The locking screw tray is a critical accessory for orthopedic internal fixation procedures, particularly for locking plate systems. It contains locking screws of various specifications (diameter, length), typically crafted from medical-grade titanium alloy. The tray features compartmentalized design
The PFNA intramedullary nail instrument set is a specialized integrated surgical tool system designed for proximal femoral fractures, particularly osteoporotic intertrochanteric fractures in elderly patients. Its core instruments include the main nail, spiral reamer, and matching locking nails. The
Advantages of mini plate instrument set1.Efficient surgical process optimizationStandardized matching designIncludes specialized drill bits, guides, depth gauges, screwdrivers, and other tools that perfectly match mini steel plates, avoiding delays during surgery caused by incompatible instruments.M
