Distal Humerus Fractures

Incidence and Distribution Overall incidence in adults is small

lt057

Majority involve the articular segment 85

Partially articular comprising 5 and nonarticular fractures comprise 10

Bimodal distribution young males 12-19 yo result of high energy trauma or elderly females with osteoporotic bone secondary to falls

Distal Humerus Fractures

Anatomy

The distal humerus is widest distally in the coronal dimension to a maximum between the medial and lateral epicondyle

The joint surface to shaft axis is 4 to 8 degrees of valgus giving rise to the carrying angle

The articular segment projects anterior to the axis of the shaft at an angle of 400

(the capitellum slightly more forward then the trochlea)

Distal Humerus Fractures

Anatomy

Medial and lateral columns roughly triangular composed of an epicondyle (non articulating) and condyle (articulating)

Displacement of condylar fragment is common due to absence of muscle attachment to oppose those attached to the epicondyles

The medial epicondyle is closely related to the ulnar nerve and is the site of attachment of the ulnar collateral ligaments This being the strongest ligament of the elbow

Distal Humerus Fractures

Mechanism and Assessment Mechanism of Injury

axial load through the elbow with the joint flexed beyond 90 degrees or direct trauma

Clinical Assessment Careful physical and neurovascular exam is

imperative checking for open wounds neurological and arterial injuries

Plain x-ray AP and Lateral while maintaining gentle longitudinal traction

Stress x-rays can help assess ligamentus stability

CT Scan to evaluate articular comminution

Distal Humerus Fractures

Treatment based on AO Classification

Nonoperative Treatment Nondisplaced distal humeral fractures

Patients who canrsquot tolerate anesthesia advanced dementia

Traction with conversion to cast functional brace or hinged brace when fracture is ldquostickyrdquo controlled motion is started

Outcomes of modern operative fixation is indicated in most cases

Other Methods ldquoBag of bonesrdquo arm is placed in a collar and cuff with as much flexion as possible elbow is left hanging free allowing gravity to exert a ligamentotaxis effect

Distal Humerus Fractures Operative

Treatment based on AO Classification

Evidence supports Operative Treatment in patients who can tolerate anesthesia with early ROM if appropriate

Displaced distal humerus fractures Exceptions

Frail or debilitated individuals Open woundsdegloving injury Blast or open crush injury Extreme osteoporosis

Intra-articular fractures

Distal Humerus Fractures Operative

Controversy in approach Triceps splitting

Triceps reflecting Triceps reflecting with anconeus pedicle Triceps sparing with and without olecranon osteotomy

Insufficient evidence to recommend or against ulnar nerve transposition

Speaker preference Triceps sparing or

reflecting for extra-articular or simple intra-articular fractures

Operative Treatment Goal is anatomic reduction ORIF

Indicated for displaced type I fractures Screws placed via lateral approach or posterior with olecranon

osteotomy for trochlea component or medial comminution headless screws may be placed anterior to posterior direction plate added to lateral column for comminution

Fixation should be stable enough to allow early ROM Excision

Contraindicated in the presence of associated elbow fractures Allows for early mobilization and less morbidity but associated

with instability Recommended treatment in old missed fractures with limited

ROM

Distal Humerus Fractures

Anatomy

Medial and lateral columns roughly triangular composed of an epicondyle (non articulating) and condyle (articulating)

Displacement of condylar fragment is common due to absence of muscle attachment to oppose those attached to the epicondyles

The medial epicondyle is closely related to the ulnar nerve and is the site of attachment of the ulnar collateral ligaments This being the strongest ligament of the elbow

Mechanism and Assessment Mechanism of Injury

axial load through the elbow with the joint flexed beyond 90 degrees or direct trauma

Clinical Assessment Careful physical and neurovascular exam is

imperative checking for open wounds neurological and arterial injuries

Plain x-ray AP and Lateral while maintaining gentle longitudinal traction

Stress x-rays can help assess ligamentus stability

CT Scan to evaluate articular comminution

Distal Humerus Fractures

Treatment based on AO Classification

Nonoperative Treatment Nondisplaced distal humeral fractures

Patients who canrsquot tolerate anesthesia advanced dementia

Traction with conversion to cast functional brace or hinged brace when fracture is ldquostickyrdquo controlled motion is started

Outcomes of modern operative fixation is indicated in most cases

Other Methods ldquoBag of bonesrdquo arm is placed in a collar and cuff with as much flexion as possible elbow is left hanging free allowing gravity to exert a ligamentotaxis effect

Distal Humerus Fractures

Mechanism and Assessment Mechanism of Injury

axial load through the elbow with the joint flexed beyond 90 degrees or direct trauma

Clinical Assessment Careful physical and neurovascular exam is

imperative checking for open wounds neurological and arterial injuries

Plain x-ray AP and Lateral while maintaining gentle longitudinal traction

Stress x-rays can help assess ligamentus stability

CT Scan to evaluate articular comminution

Distal Humerus Fractures

Treatment based on AO Classification

Nonoperative Treatment Nondisplaced distal humeral fractures

Patients who canrsquot tolerate anesthesia advanced dementia

Traction with conversion to cast functional brace or hinged brace when fracture is ldquostickyrdquo controlled motion is started

Outcomes of modern operative fixation is indicated in most cases

Other Methods ldquoBag of bonesrdquo arm is placed in a collar and cuff with as much flexion as possible elbow is left hanging free allowing gravity to exert a ligamentotaxis effect

Distal Humerus Fractures Operative

Treatment based on AO Classification

Evidence supports Operative Treatment in patients who can tolerate anesthesia with early ROM if appropriate

Displaced distal humerus fractures Exceptions

Distal Humerus Fractures

Capitellum Fractures Treatment Nonoperative Treatment

Primarily for nondisplaced fx Posterior splint immobilization for 3 weeks

Operative Treatment Goal is anatomic reduction ORIF

Indicated for displaced type I fractures Screws placed via lateral approach or posterior with olecranon

osteotomy for trochlea component or medial comminution headless screws may be placed anterior to posterior direction plate added to lateral column for comminution

Fixation should be stable enough to allow early ROM Excision

Contraindicated in the presence of associated elbow fractures Allows for early mobilization and less morbidity but associated

with instability Recommended treatment in old missed fractures with limited

ROM

Distal Humerus Fractures

Capitellum Fractures Treatment Nonoperative Treatment

Primarily for nondisplaced fx Posterior splint immobilization for 3 weeks

Operative Treatment Goal is anatomic reduction ORIF

Indicated for displaced type I fractures Screws placed via lateral approach or posterior with olecranon

osteotomy for trochlea component or medial comminution headless screws may be placed anterior to posterior direction plate added to lateral column for comminution

Fixation should be stable enough to allow early ROM Excision

Contraindicated in the presence of associated elbow fractures Allows for early mobilization and less morbidity but associated

with instability Recommended treatment in old missed fractures with limited

ROM

Distal Humerus Fractures Operative

Treatment based on AO Classification

Coronal Shear fracture OTAAO type B3

Uncommon involves capitellum trochlea or both

Usually associated with elbow dislocation

Often missed on plain x-rays 66 sensitivity CT recommended

Distal Humerus Fractures

Capitellum Fractures

Classification Type I Hahn-Steinthal

Fragment Large osseous component of capitellum sometimes with trochlear involvement

Type II Kocher-Lorenz Fragment Articular cartilage with minimal subcondylar bone attachment ldquo uncapping of the condylerdquo

Type III markedly comminuted

Distal Humerus Fractures

Capitellum Fractures Treatment Nonoperative Treatment

Primarily for nondisplaced fx Posterior splint immobilization for 3 weeks

Operative Treatment Goal is anatomic reduction ORIF

Indicated for displaced type I fractures Screws placed via lateral approach or posterior with olecranon

osteotomy for trochlea component or medial comminution headless screws may be placed anterior to posterior direction plate added to lateral column for comminution

Fixation should be stable enough to allow early ROM Excision

Contraindicated in the presence of associated elbow fractures Allows for early mobilization and less morbidity but associated

with instability Recommended treatment in old missed fractures with limited

ROM

Distal Humerus Fractures

Capitellum Fractures Complications

Complications Osteonecrosis uncommon

Posttraumatic arthritis increased with failure to restore articular congruity

Cubitus valgus may result with excision of the articular fragment or with associated lateral condylar or radial head fx It is associated with tardy ulnar palsy

Distal Humerus Fractures Operative

Treatment based on AO Classification

Use of locked

plating has been

controversial

proven superior in

osteoporotic bone

and comminuted

fractures

No data to go

against locked

plating

Distal Humerus Fractures Operative

Treatment based on AO Classification

Coronal Shear fracture OTAAO type B3

Uncommon involves capitellum trochlea or both

Usually associated with elbow dislocation

Often missed on plain x-rays 66 sensitivity CT recommended

Distal Humerus Fractures

Capitellum Fractures

Classification Type I Hahn-Steinthal

Fragment Large osseous component of capitellum sometimes with trochlear involvement

Type II Kocher-Lorenz Fragment Articular cartilage with minimal subcondylar bone attachment ldquo uncapping of the condylerdquo

Type III markedly comminuted

Distal Humerus Fractures

Capitellum Fractures Treatment Nonoperative Treatment

Primarily for nondisplaced fx Posterior splint immobilization for 3 weeks

Operative Treatment Goal is anatomic reduction ORIF

Indicated for displaced type I fractures Screws placed via lateral approach or posterior with olecranon

osteotomy for trochlea component or medial comminution headless screws may be placed anterior to posterior direction plate added to lateral column for comminution

Fixation should be stable enough to allow early ROM Excision

Contraindicated in the presence of associated elbow fractures Allows for early mobilization and less morbidity but associated

with instability Recommended treatment in old missed fractures with limited

ROM

Distal Humerus Fractures

Capitellum Fractures Complications

Complications Osteonecrosis uncommon

Posttraumatic arthritis increased with failure to restore articular congruity

Cubitus valgus may result with excision of the articular fragment or with associated lateral condylar or radial head fx It is associated with tardy ulnar palsy
