Partial fasciectomy is a useful treatment option for symptomatic plantar fibromatosis.

Plantar fibromatosis is a rare, benign fibroproliferative disorder of the plantar fascia. It is considered as a low-grade tumour and it can be locally aggressive. It can present as painful swelling with impairment of local function. Upon failure of non-operative management, surgical treatment options include total fasciectomy or partial fasciectomy. Although surgical excision is the mainstay of treatment, recurrence rate can be up to 60%. The aim of this study was to determine the recurrence and complication rates of surgically treated plantar fibromatosis. A retrospective study was conducted involving patients who had a confirmed diagnosis and excision of plantar fibromatosis treated in our institution between 2011 and 2016. Demographic data, follow-up duration, recurrence and complications were reviewed. Eighteen patients underwent 19 operations. Mean age was 41.3 years (20-57). There were 12 male patients. The main presenting features were pain, swelling and impairment of function. They were investigated by ultrasound scan (12 feet, 63%) and/or magnetic resonance imaging (8 feet, 42%). Two patients (11%) had prior surgery at other institutions whilst 3 patients (17%) had multiple nodules at presentation. All patients underwent partial fasciectomy of the plantar fibromatosis. At up to 5 years follow-up, one patient (6%) had a recurrence in our series whilst 3 patients (17%) had scar related problems (2 patients with scar pain and one patient had hypersensitive scar that resolved after 12 months). Symptomatic plantar fibromatosis can be effectively treated with partial plantar fasciectomy.
