This document discusses elbow fractures and dislocations. It begins by classifying various types of elbow fractures including intercondyler fractures, condylar fractures, capitulum fractures, radial neck fractures, and fractures of the olecranon and coronoid processes. It then discusses classifications for many of these fractures. The document also covers elbow dislocations, describing the most common types, associated injuries, symptoms, imaging, treatment, and potential complications.

DISLOCATIONS
TRINITY ANGONI

2. ELBOW FRACTURES
Intercondyler fractures
Condyler fractures
Capitulum fractures

fractures

3. Intercondyler fractures of the
humerus
Riseborough and Radin Classification
 Type I: Nondisplaced
 Type II: Slight displacement with no rotation
between the condylar fragments in the frontal
plane
 Type III: Displacement with rotation
 Type IV: Severe comminution of the articular
surface

4. Riseborough and Radin
classification

5. Condylar Fractures
 Milch Classification
 Two types for medial and lateral; the key is the
lateral trochlear ridge.
 Type I: Lateral trochlear ridge is left intact.
 Type II: Lateral trochlear ridge is part of the
condylar fragment (medial or lateral).

6. Humeral epihpyses anatomy

7. Milch classification

8. Milch classification

9. Capitulum fractures
Bryan and Morey classification
Type I: Hahn-Steinthal fragment. Large osseous
component of capitellum, sometimes with
trochlear involvement
Type II: Kocher-Lorenz fragment. Articular
cartilage with minimal subchondral bone
attached: “uncapping of the condyle”
Type III: Markedly comminuted

10. Hahn-Steinthal fragment

11. Kocher-Lorenz fragment

12. Radial head fractures
 A fall on the outstretched hand forces the
elbow into valgus and pushes the radial head
against the capitulum.

13. Head of radius fractures
Mason classification
 Type I An undisplaced vertical split in the radial
head
 Type II A displaced single fragment of the head
 Type III The head broken into several
fragments (comminuted).

14. Mason’s Classification

15. Olecranon process fractures
Two broad types of injury are seen:
(1) a comminuted fracture which is due to a direct blow
or a fall on the elbow
(2) a transverse break, due to traction when the patient
falls onto the hand while the triceps muscle is
contracted.
These two types can be further sub-classified into
(a) Displaced
(b) Undisplaced fractures.
More severe injuries may be associated also
with subluxation or dislocation of the ulno-humeral
joint.

16. Olecranon process fractures
Morrey Classification
 Type I: Undisplaced, stable fractures
 Type II: Displaced, stable
 Type III: Displaced, unstable fractures

17. Olecranon fractures

18. Radial neck fractures
 A fall on the outstretched hand forces the
elbow into valgus and pushes the radial head
against the capitulum.
 In children the bone fractures through the neck
of the radius.

19. Coronoid process fractures
Regan and Morrey classification
Type I: Fracture avulsion just the tip of the
coronoid
Type II: Those that involve less than 50% of
coronoid either as single fracture or multiple
fragments
Type III: Those involve >50% of coronoid
Subdivided into those
(A)without elbow dislocation
(B)with elbow dislocation

20. Regan and Morey classification

21. Treatment
 Surgical treatment is given as appropriate
 Plates and screws for comminuted fractures
 Headless or lag screws for uncomminuted
fractures
 Collar and cuff for splinting or other splints in
non surgical intervention.

22. Physiotherapy mx
Problems
 Stiffness of the elbow
 Loss of extension and flexion and sometimes
pronation and supination
 Pain
 Myositis ossificans
 Vascular insufficiency
 Nerve damage (ulnar and median nerve)
 Mul union

23. Physio mx
Problems
 Delayed union
 Non union
 Elbow instability
 Muscle spasm
 Muscle weakness
 Muscle atrophy
 Joint deformity
 Bone infection (osteomyelitis)
 Osteoporosis loss of bone density as a result of reduced
functionality
 Thrombus formation

24. Physio mx
 Ultrasound to loosen adhesions/ myositis
ossificans
 Massage (hacking) and muscle stretch to
realese contractures
 Range of motion exercizes to increase
extension, flexion, supination and pronation.
 Tens/ift for pain medication and muscle spasm.

25. Physio mx
 Circulatory exercizes for vascular insufficiency
 Nerve glides for nerve damage if neuropraxic
 Nerve stretching
 Immobilisation in cast in cases of mal
union, delayed union and non union then
refere for re assesment.
 Immobilising in armsling for elbow instability.
Untill healing takes place.

26. Physio mx…..
 Muscle strengthening exercizes for muscle
weakness, muscle atrophy and immobility
osteoporosis.
 Order for a check x-ray if there is joint
deformity for appropriate progression of
therapy.
 with chronic uhealing wounds discharging pus
suspect osteomyelitis, and recommend biopsy
for microbiology examination.
 tubi grip will be appropriate for dvt (paget von
schruetter disease).

27. ELBOW DISLOCATION

28. Elbow dislocation
General
• The most common type of dislocation in
children and the second most common type in
adults, second only to shoulder dislocation
• Young adults between the ages of 25–30 years
are most affected and sports activities account
for almost 50% of these injuries

29. Types of elbow dislocations
 Posterior
Posterolateral: >90% dislocations
Posteromedial
 Anterior (side swipe)
 Lateral
 Medial
 Divergent (rare)
Anterior-posterior type(ulna posterior, radial head
anterior).
Mediolateral (transverse) type (distal humerus
wedged between radius lateral and ulna medial).

30. Types of elbow dislocations
 Posterior dislocation: caused by a fall on the
outstretched hand
 Anterior dislocation: usually a high energy
trauma (side swipe in motor vehicle drivers)
 Lateral dislocation: a medialy directed force on
the humerus drives the trochlea in the same
direction causing the ulnar to be displaced
laterally
 Medial dislocation: a lateraly directed force will
drive the trochlea in the same direction and
causing the ulnar to be displaced medialy.

31. Types cont…..
 Divergent: a dislocation which wedges the
humerus between the ulnar and radius. Either
antero-posterior or mediolateral.

32. Types cont……

33. Clinical
• Associated injuries include fracture of the radial
head, injury to the brachial artery and median
nerve

34.  Symptoms
• Inability to bend the elbow following a fall on
the outstretched hand
• Pain in the shoulder and wrist
• On physical exam: The most important part of
the exam is the neurovascular evaluation of
 the radial artery, and median, ulnar and radial
nerves

35.  Imaging
• Plain AP and lateral radiographs
• CT and MRI scans are seldom necessary

36.  Treatment
• Reduce dislocation as soon as possible after
injury
• Splint for 10 days
• Initiate ROM exercises, NSAIDs

37. Complications
• Loss of ROM of elbow especially extension
• Ectopic bone formation
• Neurovascular injury
• Arthritis of the elbow
