Study Notes

Schatzker Classification

Six types categorize tibial plateau fractures based on displacement and location.
Type 1: Lateral plateau split; Type 2: Lateral plateau split with depression.
Type 3: Lateral depression; Type 4: Medial plateau split (risk of dislocation).
Type 5: Bicondylar fracture; Type 6: Dissociation of metaphysis and diaphysis.

Kanavel's Signs

Four clinical signs indicating possible flexor pyogenic tenosynovitis.
Fusiform swelling of the finger.
Slightly flexed posture of the involved digit.
Pain during passive extension of the involved finger.
Pain upon palpation of the flexor sheath.

Pelvic Evaluation Lines

Iliopectineal and ilioischial lines trace the anterior and posterior columns, respectively.
Tear drop line highlights the acetabulum's tear drop appearance.
Anterior wall and posterior wall lines assess structural integrity.
Sourcil line corresponds with the superior aspect of the acetabulum.

Blumensaat's Line

Drawn along the roof of the interchondylar notch of the femur on lateral radiographs.
Aids in identifying the surgical starting point for retrograde femoral nailing.

Iliopectineal Line Disruption

Disruption indicates fracture of the anterior column of the pelvis.
Important for assessing pelvic stability and potential complications.

Ilioischial Line Disruption

Marks fracture of the posterior column when disrupted.
Crucial for determining the extent of pelvic injuries.

Obturator Oblique View

Effectively visualizes the anterior column and posterior wall structures of the pelvis.

Iliac Oblique View

Optimally shows the posterior column and anterior wall, aiding in diagnostic assessments.

Letournel Classification

Two categories: Elementary (basic fractures) and Associated (fractures with additional involvement).
Elementary types include anterior wall, posterior wall, anterior column, and others.
Associated types incorporate complex fracture patterns affecting multiple structures.

Galeazzi Fracture

Characterized by a fracture in the distal radius shaft with concurrent distal radioulnar joint (DRUJ) injury.

Montaggia Fracture

Involves a fracture in the proximal ulna shaft with associated radial head dislocation or instability.

Bado Classification

Classifies fractures based on the position of the ulna and radial head dislocation.
Four types include both anterior and posterior dislocation scenarios.

Mirels Criteria

Scoring system assesses the need for prophylactic fixation of pathologic fractures.
Scores of 8 or higher indicate strong consideration for intervention.

Gartland Classification

Applied to supracondylar fractures of the humerus.
Type 1: Nondisplaced; Type 2: Displaced with intact posterior cortex; Type 3: Completely displaced with disrupted cortex.

Milch Classification

Focuses on fractures involving the lateral trochlear ridge.
Type 1 denotes intact ridge; Type 2 indicates fracture involvement.

Bohler's Angle

Norm range of 20-40 degrees in evaluating calcaneus fractures.
Flattening of the angle suggests collapse of the posterior facet.

Critical Angle of Gissane

Normal angle range is 120-145 degrees for calcaneus fractures.
Increased angle suggests posterior facet collapse.

Sanders Classification

Focuses on posterior facet fractures in the calcaneus.
Ranges from nondisplaced to comminuted fractures based on fracture lines.

Vancouver Classification

Used for categorizing periprosthetic hip fractures, important for treatment planning.

Neer and Associates Classifications

Classifies humeral fractures based on displacement and angulation.
Type 1: Minimal displacement; Type 2: More than 1 cm displacement; Type 3: Comminuted fractures.

Frykman Classification of Distal Radius Fractures

Includes eight types distinguishing between intra- and extra-articular fractures and corresponding ulnar involvement.
Types range from simple extra-articular to complex intra-articular with distal ulna involvement.
