Orthopaedic Foot Conditions Flashcards
Describe the general management of foot problems?
General management:
- Non operative management
- Analgesia
- Shoe wear modification
- Activity modification
- Weight loss
- Physiotherapy
- Orthotics including insoles and bracing
- Operative management
- Only indication for this is failure of non-operative management

What are examples of forefoot problems?
- Hallux valgus
- Hallux rigidus
- Lesser toe deformities
- Morton’s neuroma
- Metatarsalgia
- Rheumatoid forefoot
What are examples of midfoot problems?
- Ganglia
- Osteoarthritis
- Plantar fibromatosis
What are examples of hindfoot problems?
- Achilles tendonitis
- Plantar fasciitis
- Ankle osteoarthritis
- Tibialis posterior dysfunction

What is hallus valgus also called?
Bunions
What is this?
Hallus valgus
What is the aetiology of hallus valgus?
- Genetic
- Footwear
Describe the epidemiology of hallus valgus in terms of sex?
- Predominantly woman
Describe the pathophysiology of hallus valgus?
- Lateral angulation of great toe
- Tendons pull realigned to lateral of centre of rotation of toe worsening deformity
- Vicious cycle of increasing pull increasing deformity
- Sesamoid bones sublux, less weight goes through great tow
- Abnormalities of lesser toes
What is the presentation of hallus valgus?
- Pressure symptoms from shoe wear
- Pain from crossing over of toes
- Metatarsalgia
What investigation is done for hallus valgus?
- X-ray
- Determine severity of underlying bony deformity
- Exclude associated degenerative change
What is the mangement of hallus valgus?
- Non-operative
- Shoe wear modification
- Wide +/- high toe box
- Orthotics to offload pressure/correct deformity
- Activity modification
- Analgesia
- Shoe wear modification
- Operative
- Indication is failure of non-operative treatment
- Release lateral soft tissues
- Osteotomy of 1st metatarsal +/- proximal phalanx
- Good outcome but recurrence inevitable
What is indication for operative treatment of hallus valgus?
- Indication is failure of non-operative treatment
What is hallux rigidus?
Means stiff big toe, basically osteoarthritis of 1st MTP joint
What is the aetiology of hallux rigidus?
Aetiology:
- Not known
- Possibly genetic
What is the presentation of hallux rigidus?
- Many asymptomatic
- Pain
- Often at extreme of dorsiflexion
- Limitation of range of movement
What investigation is done for hallux rigidus?
X-ray
What is the mangement of hallux rigidus?
- Non-operative
- Activity modification
- Shoe wear with rigid sole
- Analgesia
- Operative
- Cheilectomy
- Remove dorsal osteophytes to stop dorsal impingement
- Arthrodesis
- 1st MTPJ fusion
- Gold standard treatment
- 1st MTPJ hemiarthroplasty
- Good option to maintain ROM
- High failure rate
- 1st MTPJ fusion
- Arthroplasty
- Cheilectomy
What is a cheilectomy?
- Remove dorsal osteophytes to stop dorsal impingement
What are the 3 classic terms of lesser toe deformities?
- Claw toes
- Flexion at proximal and distal interphalangeal joint
- Hammer toes
- Flexion of proximal interphalangeal joint and dorsiflexion at MTP joint
- Mallet toes
- Flexion at distal interphalangeal joint
What is claw toe?
- Flexion at proximal and distal interphalangeal joint
What is hammer toes?
- Flexion of proximal interphalangeal joint and dorsiflexion at MTP joint
What is mallet toes?
- Flexion at distal interphalangeal joint
What is the aetiology of lesser toe deformities?
- Imbalance between flexors/extensors
- Shoe wear
- Neurological
- Rheumatoid arthritis
- Idiopathic
What is the presentation of lesser toe deformties?
- Deformity
- Pain from dorsum and plantar side
What is the treatment of lesser toe deformities?
- Non-operative
- Activity modification
- Shoe wear
- Flatter shoes with high toe box
- Orthotic insoles
- Operative
- Flexor to extensor transger
- Fusion of interphalangeal joint
- Release MTP joint
- Shortening osteotomy of metatarsal
What is the aetiology of Morton’s neuroma?
- Mechanically induced degenerative neuropathy
- High heeled shoes
Describe the epidemiology of Morton’s neuroma in terms of age and sex?
- Females aged 40-60
