16.1. Foot Problems - Forefoot Problems Flashcards
What are the Pathological Groupings of Disease of the Foot?
- Vascular
- Infective
- Traumatic
- Autimmune
- Metabolic (Endocrine / Drugs)
- Inflammatory
- Inherited (Congenital)
- Neurological
- Neoplastic
- Degenerative
- Idiopathic
What are the Anatomical Groupings of Disease of the Foot?
- Forefoot Problems
- Midfoot PRoblems
- Hindfoot Problems
What are the major Forefoot Problems?
- Hallux Valgus
- Hallux Rigidus
- Lesser Toe Deformities
- Morton’s Neuroma
- Metatarsalgia
- Rheumatoid Forefoot
What is Hallux Valgus better known as?
Bunions
What is the Aetiology of Hallux Valgus (Bunions)?
- Genetic
- Footwear
- Being Female
What is the Pathogenesis of Hallux Valgus (Bunions)?
- Lateral Angulation of the Great Toe leads to Tendons being pulled
- They are then realigned to the Lateral Center of Rotation of worsening deformity
Note - Vicious Cycle of Increased Pull causing Increased Deformity - The Sesamoid Bones Sublux, due to the changes, and Less Weight goes through the Great Toe
- Abnormalities of the Lesser Toe occur as it progresses
What are the Symptoms of Hallux Valgus (Bunions)?
- Pressure Symptoms from Shoe-wear
- Pain from crossing over Toes
- Metetarsalgia
How is a Diagnosis of Hallux Valgus (Bunions) made?
- Clinical
2. X-Rays - Determine Severity of underlying bone deformity
What are the Non-Operative managements of Hallux Valgus (Bunions)?
- Shoe-wear Modification
- Orthotics to offload pressure
- Activity Modification
- Analgesia
What are the Operative managements of Hallux Valgus (Bunions)?
- Release Lateral Soft Tissue
- Osteotomy - 1st Metatarsal +/- Proximal Phalanx
Note - Generally good outcome but recurrence inevitable
What is Hallux Rigidus?
Osteoarthritis of the 1st Metatarsophalangeal Joint
Note - This is also known as Hallux Limitus / Non-Extensus
What is the aetiology of Hallux Rigidus?
Unknown - possibly genetic
What are the Symptoms of Hallux Rigidus?
- Many are Assymptomatic
- Pain - Often at extreme Dorsiflexion
- Limitation of Range of Movement
How is a Diagnosis of Hallux Rigidus made?
- Clinically
2. With Radiographs
What are the Non-Operative managements of Hallux Rigidus?
- Activity Modification
- Shoe-Wear with Rigid Soles
- Analgesia
What are the Operative Managements of Hallux Rigidus?
- Cheilectomy
- Arthrodesis -Fusion of bones (Gold Standard)
- Arthroplasty - Better for Low Demand Patients (High Failure Rate but good Maintenance for ROM)
What are the Lesser Toe Deformities?
- Claw Toes
- Hammer Toes
- Mallet Toes
What is the Aetiology of the Lesser Toe Deformities?
- Imbalance between Flexors / Extensors
- Shoe-Wear
- Neurological
- Rheumatoid Arthritis
- Idiopathic
What are the Symptoms of the Lesser Toe Deformities?
- Deformity
- Pain of the Dorsum of the Foot
- Pain from the Plantar Side of the Foot (Metatarsalgia)
What are the Non-Operative Treatments of Lesser Toe Deformities?
- Activity Modification
- Shoe-Wear - Flat Shoes with High Toe Box
- Orthotic Insoles - Metatarsal Bar / Dome Support
What are the Operative Treatments of Lesser Toe Deformities?
- Flexor to Extensor Transfer
- Fusion of Interphalangeal Joints
- Release Metatarsophalangeal Joint
- Shortening Osteotomy of Metatarsal
What is Morton’s Neuroma also known as?
Interdigital Neuralgia
What are the Symptoms of Morton’s Neuroma?
- Typically affects 3rd followed by 2nd Webspace / Toes
- Neuralgic Burning Pain in Toes
- Intermittent
- Altered Sensation in the Webspace
How is Morton’s Neuroma Diagnosed?
- Clinically
- Mulder’s Click
- Ultrasound / MRI
How is Morton’s Neuroma managed?
- Injection for Small Lesions
- Surgery - Excision of Lesion, including a section of normal nerve:
- a) Numbness
- b) Recurrence
- c) 30% have pain 1 year post surgery
What is characteristic for Morton’s Neuroma?
If the pain is under the Metatarsal Head, then it is, in fact, a Morton’s Neuroma
What is Metatarsalgia?
A Symptom (Not a Diagnosis) Pain of the Metatarsals
What can cause Metatarsalgia?
- Synovitis
- Bursitis
- Arthritis
- Neuralgia
- Neuromata
- Freiberg’s Disease
- Tight Gastrcnemius
What is the Treatment of Rheumatoid Forefoot?
- Non-Operative - Shoe-Wear / Orthotics / Activity etc.
- Operative:
- a) 1st Metatarsophalangeal Arthrodesis
- b) 2-5th Toe Excision Arthroplasty
