The patient has insertional Achilles tendinitis with a large bone spur off the posterior calcaneus. Achilles tendinitis can occur as both insertional and noninsertional type.1,2 Calcaneal bone spurring occurs with the insertional type.
The Achilles tendon, the largest tendon in the body, attaches to the posterior calcaneus and allows plantar flexion of the foot. Achilles tendinitis generally occurs with a sudden increase in exertional activities, such as a sudden increase in walking, jumping, or running. A period of rest permits recovery from the increased demand caused by repetitive stress on the Achilles tendon and calf.2 If patients do not rest and allow the tendon to heal after strenuous activity, tendinitis may develop. This patient went on a walking tour in Europe and she undoubtedly put much more stress on the Achilles tendon than usual. The large bone spur also places the patient at increased risk for tendinitis because it rubs against the tendon during heel motion.2
Initial treatment for insertional Achilles tendinitis includes rest and nonsteroidal anti-inflammatory drugs (NSAIDs).1,2 A steroid taper is commonly used, followed by an oral over-the-counter NSAID for acute relief. Placing the patient in a walking boot allows the Achilles tendon to rest and is generally recommended for a period of 4 to 6 weeks. A small heel lift can be used in the boot to help shorten and rest the Achilles tendon. Physical therapy should be initiated for gastrocnemius-soleus stretching and local modalities. Steroid injections to the Achilles tendon should be avoided because of the increased risk for Achilles tendon rupture. Excision of the calcaneal bone spur is a last-resort treatment option, because the procedure requires a lengthy recovery of up to 1 year for symptomatic relief. A period of at least 6 months of conservative treatment is recommended prior to considering surgery.
