Group DCase Study 4 • Rebecca Bennet • Claire Crutchley • Harm Kallu • Hilary Short • Nicky Weston
Scenario • 46 year old female • Referred by GP • Complaining of severe pain in the bottom of right foot • No medication at present • Has noticed tingling and numbness in some toes at times
Symptoms seem to indicate Tarsal Tunnel Syndrome due to following clinical presentations; • Location and severity of pain • Numbness and tingling in some toes • Pain is unilateral (Mooney & Campbell 2010)
However… Tarsal Tunnel Syndrome is often misdiagnosed! Nature of symptoms mean that there are many other pathologies with symptoms paralleling this condition (Yates 2009)
Differential Diagnosis • Polyneuropathy • Morton’s metatarsalgia • Compartment syndrome of deep flexor compartment • Calcaneal spur • Arthrosis of joints of foot • Plantar fasciitis • Inflammatory changes to ligaments Not an exhaustive list! (Antoniadis & Scheglmann 2008)
A variety of soft-tissue, osseous and systemic disorders can cause heel pain Common misdiagnosis include; • Plantar Fasciitis • Achilles Tendonitis • Retrocalcaneal Bursitis (Morphopedics.com, n.d.)
The Tarsal TunnelThe tarsal tunnel is a structure of the foot that is formed between the underlying bones and the overlying fibrous tissue of the flexor retinaculum.(Mooney & Campbell 2010)(Image from www.orthogate.org) Picture of tarsal tunnel
What is Tarsal Tunnel Syndrome? It is a relatively uncommon entrapment neuropathy caused by damage to and/or compression of the posterior tibial nerve within the tarsal tunnel (Mooney & Campbell 2010, p 122) Presenting symptoms include; • Sharp, shooting foot pain • Numbness on sole of foot • Radiation of pain/paraesthesia along course of nerve (Patient.co.uk)
Short term plan Conservative management focuses on therapies to reduce unpleasant and painful symptoms including; • Clinical padding such as valgus filler pads or medial heel wedges • Orthosesor bespoke shoes • Injections of corticosteroids into tarsal tunnel • Medication for pain • Exercises to maintain muscle strength • Control of any underlying contributory conditions (Mooney & Campbell 2010, p 122)
Long term plan • If job involves standing – job counselling could be suggested? • Failure of conservative treatment means surgical intervention could be indicated • Surgery can enlarge the tarsal tunnel and reduce the pressure on the tibialnerve • Varied success rates!
