Epiphysis and epiphyseal injuries in brief

1. The
Epiphysis
Dr. Utsav Agrawal

2. Anatomy
A typical long bone
consists of :
-Diaphysis
-Metaphysis
-Epiphysis

3. Types of Epiphysis
 Pressure epiphyses
 Traction epiphyses
 Atavistic epiphyses
 Aberrant epiphyses

4. Development
 Epiphysis develop from secondary centres
of ossification
 They develop by process of enchondral
ossification

5. Lesions at epiphysis
chondroblastoma
giant cell tumour
intraosseous ganglion
osteomyelitis
clear cell chondrosarcoma
Osteonecrosis
Osteochondritis dessicans

6. Rare :
 osteosarcoma
 aneurysmal bone cyst
 brown tumour
 haemophilic pseudotumour
 enchondroma

7. Epiphyseal plate injuries
Classified by
-Polland
-Ogden
-Salter-Harris
 Fractures involving the epiphyseal plate at the end of the long bone
of a growing child
 Growth plate fractures account for 15-20% of major long bone
fractures and 34% of hand fractures in childhood
 Classified into 5 types based on fracture line

8. Salter & Harris Classification of
Epiphyseal plate injuries

9. Type I
Slipped Capital Femoral Epiphysis

10. Type II

11. Type III

12. Type IV

13. Type V

14. Rare types of Salter-Harris fractures
 Type VI - Injury to the perichondral structures
 Type VII - Isolated injury to the epiphyseal plate
 Type VIII - Isolated injury to the metaphysis, with
a potential injury related to endochondral
ossification
 Type IX - Injury to the periosteum that may
interfere with membranous growth
