triple arthrodesis

Management

Surgical Algorithm

 

Stage 1 Tendonitis

 

Non-operative

 

Walking cast / NSAIDS

- 6/52

 

UCBL

- 3/12

- worn inside the shoe

- ends under malleoli

- controls the heel (which must be flexible)

- supports the arch

 

Operative / Synovectomy and debridement

(+/- FDL transfer and calcaneal osteotomy +/- T Achilles lengthening)

Subtalar and Triple Arthodesis

Biomechanics

 

Able to achieve relatively high level of function after STJ fusion

- previously believed that isolated STJ fusion should not be performed

- believed that triple arthrodesis was operation of choice for hindfoot

- STJ fusion has superior result with less stress on AJ

 

Average loss of DF 30% / PF 10%

 

Position of hindfoot determines flexibility of transverse tarsal (CCJ & TNJ) joints

- imperative that fusion be positioned in ~ 5o valgus
