The aim of this study is to assess the efficacy of planter displacement calcaneal osteotomy for intractable plantar fasciosis by decreasing the tension of the plantar fascia around the calcaneal attachment while keeping the plantar fascia intact.

Plantar fasciosis is a leading cause of heel pain in adults and represents a degenerative rather than inflammatory condition of the plantar fascia. Most cases resolve with conservative measures; however, up to 10-15% remain symptomatic and may require surgical intervention. Plantar fascia release-either open or endoscopic-remains a standard surgical option for recalcitrant cases. However, this procedure may compromise foot biomechanics. Recent biomechanical and clinical studies have demonstrated that partial or complete release reduces longitudinal arch height and increases midfoot strain, particularly when more than 50% of the fascia is divided. Such alterations in load distribution can result in lateral column overload, metatarsalgia, and sinus tarsi pain. Endoscopic release has also been associated with medial arch reduction and the development of lateral column symptoms within months postoperatively, further highlighting these risks. Additionally, comparative studies report wound complications, nerve irritation, and recurrence of heel pain in a notable subset of patients undergoing plantar fasciotomy. Up to 50% of patients may experience persistent or recurrent pain following the procedure. Entrapment of the first branch of the lateral plantar nerve (Baxter's nerve) is another under-recognized cause of chronic heel pain, often coexisting with or mimicking plantar fasciosis. Decompression of Baxter's nerve, either alone or combined with limited plantar fascia release, has been shown to improve outcomes in resistant cases. Given these limitations, calcaneal osteotomy has emerged as alternative surgical strategies. By altering the mechanical axis of the calcaneus and inducing localized bone remodeling, these techniques aim to unload the plantar fascia insertion without compromising arch stability. Early reports suggest that calcaneal osteotomy, particularly when combined with Baxter's nerve release, may offer superior pain relief and functional recovery in recalcitrant plantar fasciosis.
