AO classification

Professional Technical IVT

Comprehensive fracture classification system developed by the AO Foundation for systematic categorization of fractures.

Technical Term Full entry →

arthroplasty

Intermediate Technical IVT

Surgical reconstruction or replacement of a joint, often performed as salvage treatment for severe trauma.

Technical Term Full entry →

Articular cartilage defect

Intermediate Technical IVT

Damage to the smooth cartilage surface covering joint bones, often resulting from trauma or degenerative processes.

Technical Term Full entry →

articular congruity

Advanced Technical IVT

The precise anatomical alignment and smooth surface continuity of joint surfaces after fracture repair.

Technical Term Full entry →

articular depression

Intermediate Technical IVT

A traumatic displacement of articular cartilage and underlying bone below the normal joint surface level.

Technical Term Full entry →

Articular impaction

Advanced Technical IVT

Compression and depression of joint surface bone due to axial loading forces during trauma.

Technical Term Full entry →

articular step-off

Intermediate Technical IVT

A displacement of joint surface fragments creating an uneven articular contour that may lead to post-traumatic arthritis...

Technical Term Full entry →

ATLS

Professional Technical IVT

Advanced Trauma Life Support: a systematic approach to trauma patient assessment and management.

Abbreviation Full entry →

avascular necrosis

Intermediate Technical IVT

Death of bone tissue due to interrupted blood supply, commonly occurring after certain fractures or dislocations.

Technical Term Full entry →

Bicortical purchase

Intermediate Technical IVT

Screw fixation technique engaging both the near and far cortical bone surfaces for enhanced stability.

Technical Term Full entry →

biomechanical failure

Professional Technical IVT

Loss of structural integrity in a fracture repair construct due to inadequate mechanical properties.

Technical Term Full entry →

bone void filler

Intermediate Technical IVT

Synthetic or biological material used to fill defects in bone during fracture repair or reconstruction.

Technical Term Full entry →

bridge plating

Professional Technical IVT

A fixation technique where the plate spans across the fracture without direct contact with all bone fragments.

Technical Term Full entry →

buttress plate

Professional Technical IVT

An orthopedic implant that supports bone against axial loading forces and prevents collapse.

Technical Term Full entry →

callus formation

Intermediate Technical IVT

The natural healing process where new bone tissue develops around a fracture site during repair.

Technical Term Full entry →

cancellous impaction

Intermediate Technical IVT

Compression of spongy bone trabeculae due to traumatic force, commonly seen in metaphyseal regions.

Technical Term Full entry →

Cerclage wiring

Intermediate Technical IVT

A fixation technique using wire loops encircling bone to reduce fractures or secure implants.

Technical Term Full entry →

comminuted fracture

Intermediate Technical IVT

Fracture pattern where the bone is broken into three or more fragments.

Technical Term Full entry →

compartment syndrome

Professional Technical IVT

Medical emergency caused by increased pressure within a muscle compartment that compromises blood flow.

Technical Term Full entry →

consolidation

Intermediate Technical IVT

The final stage of bone healing where the fracture site achieves complete structural integrity.

Technical Term Full entry →

construct failure

Intermediate Technical IVT

Mechanical breakdown of the bone-implant system resulting in loss of fracture stability or fixation integrity.

Technical Term Full entry →

Cortical breach

Intermediate Technical IVT

Perforation or disruption of the cortical bone wall, often occurring during surgical procedures.

Technical Term Full entry →

cortical defect

Intermediate Technical IVT

A gap or void in the hard outer layer of bone following trauma or surgical intervention.

Technical Term Full entry →

cortical window

Intermediate Technical IVT

A surgically created opening through the cortical bone to access the medullary canal or facilitate hardware removal.
