common foot and ankle conditions Flashcards
treatment options
Non-operative management Analgesia Shoe wear modification Activity modification Weight loss Physiotherapy Orthotics including insoles and bracing operate only if failure of non operative
pathological grouping
Vascular (ischaemic) Infective Traumatic Autoimmune Metabolic (endocrine /drugs) Inflammatory Inherited (congenital) Neurological Neoplastic Degenerative Idiopathic
forefoot problems
hallux valgus Hallux rigidus Lesser toe deformities Morton’s neuroma Metatarsalgia Rheumatoid Forefoot
hallux valgus
bunions genetic increased in footwear female symptoms: pressure symptoms from shoe wear pain crossing over toes metatarsalgia
pathogenesis
Tendons pull realigned to lateral of centre of rotation of toe worsening deformity
Vicious cycle of increased pull creating increased deformity
sesamoid bones sublux-less weight goes through great toe-> abnormalities of lesser toes
hallux valgus
Shoe wear modification (wide +/- high toe box)
Orthotics to offload pressure/correct deformity
Activity modification
Analgesia
Operative
-release lateral soft tissues
osteotomy 1st metatarsal +/- proximal phalanx
scarf osteotomy
hallux rigidus
osteoarthritis of 1st MTP joint Possibly genetic – typical shape of metatarsal head is slightly pointed rather than rounded Possibly multiple microtrauma Pain on dorsiflexion Limited movement
management
Activity modification
Shoe wear with rigid sole
Analgesia
Cheilectomy (remove dorsal impingement) (remember)
Arthrodesis 1st MTPJ fusion
Arthroplasty
lesser toe deformities
Claw toes
Hammer toes
Mallet toes
Aetiology
pain from plantar side
metatarsalgia
imbalance of flexors and extensors
treatment
Activity modification
Shoe wear – flat shoes with high toe box to accommodate deformity
Orthotic insoles – metatarsal bar/dome support
Operative Flexor to extensor transfer Fusion of interphalangeal joint Release metatarsophalangeal joint Shortening osteotomy of metatarsal
morton’s neuroma
plantar digit nerves
Mechanically induced degenerative neuropathy
females 40-60
Frequently associated with wearing high heeled shoes
Common digital nerve relatively tethered to one metatarsal and movement in adjacent metatarsal causing mechanical shear
Symptoms
Typically affects 3rd followed by 2nd webspace/toes
Neuralgic burning pain into toes
Intermittent
Altered sensation in webspace
diagnosis and management
mulder’s click
Steroid injection for small lesions
Surgery – excision of lesion including a section of normal nerve
metatarsalgia
symptom not a diagnosis
Synovitis, bursitis, arthritis, neuralgia, neuromata, Freiberg’s disease
tight gastrocnemius if not obvious
rheumatoid forefoot
Non-operative – shoewear/orthotics/activity etc Operative Many described techniques Current gold standard 1st MTPJ arthrodesis 2-5th toe excision arthroplasty
Midfoot problems
Ganglia
Osteoarthritis
Plantar fibromatosis
