Pain following a calcaneal fracture can arise from direct injury, traction injury, idiopathic mechanisms such as reflex sympathetic dystrophy/complex regional pain syndrome (CRPS), or nerve damage. Since there is no single standardized definition or diagnosis for post-surgical nerve pain, such cases are described in the literature as neurapraxia, postoperative neuroma, unexplained heel pain, hypersensitive scar, or CRPS. Typically, this type of pain manifests as burning, paresthesia, dysesthesia, and hyperesthesia.
The tibial nerve plays a crucial role in the sensory and motor innervation of the heel. Following a calcaneal fracture, direct nerve injury, compression, or inflammation of the surrounding tissues may contribute to pain. Pulsed radiofrequency (PRF) has been shown to alleviate chronic pain by delivering an electrical field to the nerve tissue at a controlled temperature of \<42°C without causing nerve damage. Additionally, there is evidence supporting PRF's effectiveness in pain relief for patients with various chronic conditions.
In our study, the investigators aim to evaluate patients with persistent pain after a calcaneal fracture who have undergone PRF treatment of the posterior tibial nerve. By monitoring these patients immediately after the intervention, we will assess changes in their pain scores. Additionally, the investigators will compare them to patients with post-calcaneal fracture pain who have opted not to undergo the procedure.
