Name some causes for Charcot deformity.

diabetes
syphilis
leprosy
syringomyelia
polio
spina bifida
chronic alcoholism

2

What are the 2 theories for the Charcot process?

1. neurovascular- increased blood flow from autonomic neuropathy --> bone resorption
2. neurotramatic --> repeated trauma on an insensate foot results in joint destruction

3

What is the Eichenholtz classification for Charcot deformity?

0) risk factor- no radiographic changes but the diabetic patient has a sprain or fx
1) development/ fragmentation- osteochondral fragmentation and debris formation
2) coalescence- absorption of debris and fusion of fragments into bone
3)reconstruction/consolidation- trabecular remodeling and osseous proliferation and ankylosis

4

Name some differentials for Charcot joint disease.

acute septic arthritis
RA
psoriatic arthritis
OA
neoplasms

5

what is the mainstay of treatment for acute neuropathic arthropathy?

cessation of WB to prevent further destruction

6

Name 3 immobilizers used in the care for acute Charcot with deep ulceration.

bivalve cast
CAM walker
CROW boot

7

what does CROW boot stand for?

charcot restraint orthotic walker

8

what are the goals of a charcot reconstruction?

stable, plantigrade foot with the ankle at 90 deg, hindfoot at 5-10 deg of valgus rotation

9

what is the anatomic classification for Charcot?

Brodsky

10
