Study Notes
Neuropathic Bone Disease Overview
- Neuropathic bone disease, specifically Charcot foot, is a progressive condition characterized by joint dislocation, pathological fractures, and severe pedal architectural destruction.
Objectives
- Understanding the etiology and pathophysiology of neuropathic bone disease
- Learning diagnostic testing and features of neuropathic bone disease
- Identifying treatment options for neuropathic bone disease
Definition of Charcot Foot
- Charcot foot is defined as a progressive condition involving joint dislocations, pathological fractures, and significant destruction of the foot's architecture.
6 D's of Charcot Foot
- Destruction
- Debris
- Dislocation
- Distention
- Disorganization
- Increased Density (subchondral sclerosis)
Etiologies of Neuropathic Bone Disease
- Diabetes Mellitus: Most common cause
- Tabes dorsalis
- Leprosy
- Syringomyelia
- Steroids
- Alcoholism
- Pernicious anemia
- Spinal Disorders (MS, CMT)
- Paraneoplasms
- Transplant (Kidney - 20%, Kidney-pancreas - 31% )
Statistics of Charcot Neuroarthropathy
- Prevalence in the general diabetic population: 0.1-7.5%
- Prevalence in diabetic patients with neuropathy: Up to 35%
- Typically develops after 10+ years of diabetes
- Bilateral occurrence: 9-75%
- Mean age of onset: 50.3 years
Neuropathic Bone Disease Pathophysiology
- Neurotraumatic Theory: Overuse injuries combined with lost protective sensation can lead to acute or repetitive microtrauma, causing continued tissue destruction and resulting in fractures and dislocations.
- Neurovascular Theory: Vasomotor neuropathy with intact blood flow can cause arteriovenous shunting, leading to excessive bone resorption and bone weakness, contributing to fractures and dislocations during weight-bearing.
- Increased Inflammatory Response: Osteoclast-osteoblast imbalance with increased osteoclasts leads to bone lysis and further inflammation, resulting in bone and joint destruction.
- RANK L pathway: Increased blood glucose, lack of RAGE, Increased AGES, OPG, ↑ RANKL, decreased CGRP, decreased eNOS, and repetitive trauma are all factors in bone destruction.
Histological Aspects
- Bone and cartilage debris within synovium
- Cartilage replacement by fibro-osseous tissue
Risk Factors for Charcot Arthropathy
- Neuropathy (sensory, autonomic, motor)
- High plantar pressure
- Foot Ulcers
- Age
- Obesity
- Trauma
- Instabilities
- Achilles tendon/gastrocsoleus contracture
- Peripheral vascular disease
- Physical activity levels
Eichenholtz Classification (Stages)
- This classification system describes the natural history of Charcot arthropathy in stages, based on clinical and radiographic findings. Stages are based on the level of involvement, progression, and symptoms (e.g., erythema, swelling, bone breakdown) - Stage 0 includes patients at risk for developing Charcot (neuropathy with acute injury).
Brodsky Classification (Anatomic)
- This classification system divides Charcot arthropathy based on anatomical location of the joint affected. This is helpful in planning treatments and determining prognosis. Locations include the tarsometatarsal, Chopart's/subtalar, ankle, calcaneus, multiple regions, sequential, and concurrent regions, and forefoot.
Clinical Features
- Red, hot, swollen foot
- Temperature difference (> 2 degrees Celsius)
- Usually accompanied by sensory neuropathy
- Pain may not correlate directly with the extent of bone destruction
- Bilateral involvement in 9-30% of cases
Diagnosis
- Primarily based on clinical features, including redness, heat, swelling, and the presence of sensory neuropathy
- Radiographs and imaging (cortical fractures, periosteal reaction, joint debris, deformity, dislocation, rocker bottom deformity, lack of skin break)
Differential Diagnosis
- Infection
- Rheumatoid arthritis
- Osteoarthritis
- Gout
- Osteomyelitis
- Other conditions (important to rule out similar conditions to aid accurate diagnosis)
Osteomyelitis vs Charcot
- Presence of ulcers can complicate the diagnosis as x-ray findings can be similar.
- Further imaging (e.g., bone scans, MRI) or a bone biopsy might be needed to distinguish between Charcot and osteomyelitis. Accurate diagnosis/imaging depends on suspicion of possible conditions.
Nuclear Medicine for Diagnosis
- Three-phase Tc-99m MDP bone scan is highly sensitive but has reduced specificity due to other causes of bone remodeling
- Ga67 scan has high false-positive rate
- In-111 scan has high sensitivity and specificity for diagnosing osteomyelitis and Charcot foot
- Combined scans increase diagnostic confidence (e.g., Tc99MDP and Tc99HMPAO)
- Different markers provide better specificity in different suspected cases
MRI in Diagnosis
- T1 images can show decreased signal intensity
- T2 images show increased signal intensity
- STIR images show high signal marrow edema
- Bone marrow edema might present near ulcers, revealing sinus tracts (suggestive of infection)
- Charcot edema typically appears in a periarticular fashion
Probing to Bone
- Ability to probe to bone can be helpful in diagnosing osteomyelitis but has limitations
- Cannot differentiate between infection and Charcot
- Further imaging and studies are needed to distinguish between the pathologies
Bone Biopsy
- Considered the "gold standard", but only definitive diagnosis for Charcot vs osteomyelitis
- Helpful in diagnosing infection and isolating organisms; crucial for treatment decisions..
- Before biopsy, patients generally need antibiotics stopped for several half lives
Sequelae
- Foot and ankle deformity
- Increased pressure
- Ulceration
- Soft tissue and bone infection
- Partial amputation
- Limb loss
- 25%-30% chance of developing Charcot in the contralateral extremity
- Death
Treatment (General)
- Conservative care is often the initial approach to manage inflammation, pain, and protect the foot.
Treatment (Conservative)
- Extra-depth or custom-molded shoes
- Pressure-relieving orthotics
- Total contact casts
- Other similar methods (e.g., CAM boots, CROW walkers, AFOs)
Treatment (Surgical)
- Exostectomy (removal of bone spurs)
- Arthrodesis (fusion of bones)
- Realignment osteotomies (correction of bone misalignments)
- Management of soft tissue and osseous infections
- Amputation (partial foot, below knee, or above knee)
Treatment (Surgical - General)
- Extensive medical workup required before surgery
- Non-weight bearing (NWB) or partial weight bearing (PWB) is usually necessary
- Optimizing vascular status is critical
- Renal and cardiac conditions impact outcomes
- Factors like surgical planning and individual patient specifics are important for tailored treatment.
3D Printing
- Used for patient education
- Useful for surgical planning
- Useful for student, resident, and fellow education
- Used in research
- Patient-specific 3D models may improve outcomes and reduce surgical errors
