Charcot’s Foot A Neuropathic Arthropathy
Caused by repetitive trauma in the setting of:
• Diminished sensation & proprioception• Motor neuropathy results in muscle
imbalance & abnormal weight bearing.• “Rocker Bottom Deformity” a convex deformity of the foot’s plantar
aspect caused by the collapse of metatarsal bones

Aetiopathogenesis
Peripheral sensory neuropathy is always present +/- motor.
Autonomic neuropathy leads to increased blood flow.( plethysmography & uptake of isotopes).
Trauma may be an important precipitating factor, although 2/3rd of patients don’t remember any injury.
Bone metabolism both osteoblastic and osteoclastic activities are increased.

Epidemiology
Incidence : 0.1 – 0.5 % . Increased in patients with neuropathy.Common in the 4th or 5th decades of life.Bilateral in 30 % of patients. Sex difference : NoType 1 or type 2: Both are at risk.Majority: in the mid foot but any bone or
joint in the foot or ankle can be affected.

Clinical Features and Diagnosis
Acute Charcot Warm, inflamed and swollen. Misdiagnosed as cellulitis, osteomyelitis or
inflammatory arthropathy as gouty or septic.Although sensory neuropathy, pain is
common feature followed by discomfort.Diagnosis by exclusion as investigations in
early stages are negative.

Clinical Features and Diagnosis
High index of suspicion is necessary so that appropriate treatment is immediately instituted to prevent severe deformity!

Charcot Arthropathy Mansoura 2nd International DF Training Course
Clinical Features and Diagnosis
Chronic Charcot, may be months, painless, without temperature difference and deformed.
Reactivation by further trauma is frequent.Patients are at high risk of ulceration and
amputation, so long term follow up is recommended.

Investigations
X-ray : Early; absent or subtle finding. Late; bone and joint destruction, fragmentation.
Tc bisphosphonate bone scan: Increased bone uptake.
In labeled leucocytes scan to differentiate from osteomyelitis.
MRI: Bone marrow oedema is the earliest sign.

Charcot Arthropathy Mansoura 2nd International DF Training Course
Treatment
1. Immobilization:
Total Contact Cast (TCC), Removable Cast Walker (RCW).

Charcot Arthropathy Mansoura 2nd International DF Training Course
Treatment
1. Immobilization:
Almost 16 weeks (3-6 months) but may be more. (temp gradient less than 1 on 2 occasions or radiology).
![Page 18: Charcot Arthropathy](https://reader036.vdocument.in/reader036/viewer/2022081420/56815adc550346895dc8a9a7/html5/thumbnails/18.jpg)

Treatment
2. Radiotherapy and Ultrasound:
May be useful in conjunction to offloading but only few small studies.

Treatment
3. Pharmacological Treatment.
Pilot study first using pamidronate,1994. Other Bisphosphonates were used to decrease
disease activity and bone turnover markers. Calcitonin were also used. Given for 12 weeks or till temp gradient is less than
2 on 2 consecutive visits.

Treatment
4. Surgical treatment: No role in acute. Later may be to remove bony deformities or
constructive surgeries to achieve a stable shape. Techniques include; Arthrodesis, exostectomies, reconstruction and Achilles tendon lengthening.
