Q

Which Coalition mimics pseudoarthrosis?

A

CN Coalition

17
Q

Based on patient’s age, who should be given arthroplasty vs arthrodesis

A

Juvenile - Arthroplasty
Adult - Arthrodesis

18
Q

What are the two extra-articular coalitions?

A
  • Calcaneonavicular
  • Cubonavicular
19
Q

What are the intra-articulate coalitions

A
  • Talocalcaneal
  • Talonavicular
  • Calcaneocuboid
  • Naviculocuneiform
20
Q

Match arthroplasty and arthrodesis to extra-articular and intra-articular involvement

A

Extra-articular - arthroplasty
Intra-articular - arthrodesis

21
Q

List some characteristics of secondary arthritic changes

A
  • Joint beaking
  • loss of joint clarity
  • joint irregularity/adaption
22
Q

Is arthroplasty or arthrodesis preferred for secondary arthritic changes?

A

Secondary arthritic changes - arthrodesis
No secondary arthritic changes - arthroplasty

23
Q

Peroneal spastic flatfoot without tarsal coalition can be caused by a rare condition called

A

accessory aneterolateral Tamar facet (AALTF) - restricts the motion of the STJ causing peroneal spasm

24
Q

How does intraarticular coalition size affect treatment plan?

A

Less than 50% joint involvement - arthroplasty
More than 50% joint involvement - arthrodesis

25
Q

What is the procedure for an extra-articulation Calcaneonavicular coalition

A

Badgley procedure aka EDB arthroplasty

26
Q

What is the preferred surgical technique method for an intra-articulated arthroplasty?

A

Direct medial approach
- take the TP/FDL tendons dorsally
- take the NV bundle/FHL plantarly
- resect the coalition

27
Q

when would you do a single arthrodesis?

A
  • intra-articular coalition
  • No secondary arthritis
28
Q

When would you do a triple arthrodesis?

A
  • secondary arthritis
29
Q

On MRI what sign do you see for a calcaneonavicular coalition

A

Reverse anteater sign

30
Q

On MRI what sign do you see for a talocalcaneal coalition

A

Drunken Waiter sign
