compartment syndrome

Complications

Undercorrection /  loss of correction 

 

Most important factor in good results and duration of results

- must correct to 8o of valgus

- mechanical axis must pass through lateral joint line

 

HTO Insufficient Correction

 

Causes

- inadequate initial correction

Compartment Syndrome

Circulation of tissues within a closed osteofascial space are compromised by increased pressure within that space

 

Most common 

- anterior leg compartment

- flexor compartment forearm

- deep posterior leg compartment

 

Aetiology

- fascia & skin

- POP
