Comparison between the effect of Steroid Injection, Prolotherapy Local Injection and Extracorporal Shock Wave Therapy in Treatment of Symptomatic Calcaneal Spur

Abstract

Abstract Background Calcaneal spurs are common cause of heel pain occurring anywhere along the calcaneal tuberosity and most frequently found at the insertion of the plantar fascia. They are usually asymptomatic, but when they are painful, the condition is generally the result of inflammation of the insertional fibers of the plantar fascia at the medial tuberosity. Symptomatic calcaneal spurs are often found in association with plantar fasciitis. Like plantar fasciitis, calcaneal spurs can occur alone or may be part of a systemic inflammatory condition such as rheumatoid arthritis or gout. In some patients, the cause seems to be entirely mechanical, and such patients often exhibit an abnormal gait with excessive heel strike. Objective To compare the effectiveness of dextrose prolotherapy injection, corticosteroid injection and extracorporal shockwave in symptomatic calcaneal spur, based on clinical and functional outcome measures. Patients and Methods This study was conducted on forty-five patients diagnosed with symptomatic calcaneal spur (plantar fasciitis) for more than 6 months. The patients were recruited from Physical Medicine, Rheumatology and Rehabilitation department at Ain Shams University Hospitals. Diagnosis was based on detailed history taking, full clinical examination, pain and functional assessments of the foot using visual analogue scale (VAS score) and foot function index (FFI). Results Eight weeks after treatment, the pain score by VAS was significantly improved at ESWT group mostly, less extent at prolotherapy group and least at corticosteroid group. Also the percentage of improvement in ESWT group was found higher than the other groups indicating the long term analgesic effect of ESWT. Eight weeks after treatment, the FFI subscales (pain, disability and activity limitation)and total FFI score significantly improved mostly at ESWT group, less extent at prolotherapy group and least at corticosteroid group indicating the long term beneficial effect of ESWT on the function in patients with chronic PF. Conclusion Although ESWT, dextrose prolotherapy injection, and local corticosteroid injection were all effective in the treatment of symptomatic calcaneal spur during 8weeks of follow-up but, ESWT was superior to all other modalities in its effect on pain intensity and function during daily life activities at long term follow up.
