The document discusses the epiphysis, which is one of the three parts of a long bone. It develops through enchondral ossification from secondary ossification centers. Lesions can occur at the epiphysis, including tumors and infections. Injuries to the epiphyseal plate in children are classified using the Salter-Harris system from Type I to V based on the fracture line. Rare types also exist. The epiphysis is an important part of long bone anatomy and development in the body.

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
