Natural History of ACL deficient knee is variable

- functional instability 15% - 90%

- progression to OA is variable

 

Depends on level of patient demands / activity

 

1.  Late meniscal injury in ACL deficient knee

 

15-25%

 

2.  Function

 

Daniels Am J Sports Med 1994

- 292 ACL defecients knees

Eosinophilic Granuloma

Definition

 

Langerhan's Cell Histiocytosis

- non-neoplastic disorder

- characterised by infiltration by histiocytic cells (Monocyte / macrophage lineage)

 

Group of granulomatous inflammatory processes of unknown aetiology

- involve the reticuloendothelial component of the bone marrow, parenchymal organs, and skin

 

Types 

 

E - H - L

 

Thoracic Disc Disease

Epidemiology

 

0.05% incidence

- rare due to stabilising effect of rib cage

- even more rare to have symptoms

 

Reasoning

1.  Discs are narrower

2.  Foramina larger

3.  Thoracic spine

- facet joints orientated for rotation

- lumbar spine for flexion extension

- flexion is typically the motion which ruptures annulus
