AbstractPlantar fasciitis or heel spur syndrome usually resolves with conservative management, but for patients with continued pain, surgical intervention is often pursued. In some cases, plantar fasciitis is relieved, but pain in the lateral column area appears postoperatively. This lateral column pain may be debilitating for the patient and often overlooked by the foot and ankle surgeon. The goal of the study was to identify the maximum amount of plantar fascia that can be surgically released to treat recalcitrant heel pain effectively while preventing the development of lateral column symptoms. All patients undergoing plantar fasciotomy after failing conservative treatment were eligible to participate. Patients rated their pain with an 11-point (0-10) visual analog scale (VAS) and described its location prior to and at monthly intervals after their surgery. Surgeons recorded whether 25, 50, or 66% of the plantar fascia was released during surgery. Open procedures were performed 72% of the time, and endoscopically in 28% of the patients. Key outcome variables included degree of fascial release and foot structure. Patients (n = 47) with lateral column pain after surgery (n = 15 feet) had a mean +/- S.E. of 60.6 +/- 3.0% of their plantar fascia released while those without pain (n = 35 feet) had only 48.7 +/- 1.9% of this fascia released during surgery (ANOVA, p = .019). Age, weight, body mass index, gender, smoking status, comorbidities, general health, surgical procedure, postoperative care, calcaneal inclination angle, and talar declination angle did not differ for these groups (p > .146). For this patient population, regardless of surgical technique (endoscopic or open release), lateral column symptoms were more likely to result when more than 50% of the plantar fascia was released. The report proposes that a maximum of 50% of the plantar fascia be released during surgery.
