Abstract
IntroductionMedial calcaneal neuropathy had been implicated as a source of chronic plantar heel pain.AimThe aim was to determine the presence of medial calcaneal neuropathy as a cause of chronic plantar heel pain.Patients and methodsThe present study included 43 heels obtained from 38 patients with chronic plantar heel pain and 30 apparently healthy volunteers as a control group. Clinical examination was done. Sensory nerve conduction study of the medial calcaneal nerve was performed. This was a single-center, public hospital-based study. It was designed as a cross-sectional examination of consecutive patients with chronic plantar heel pain.ResultsThere were 27 (62.79%) heels, from 23 (60.52%) patients, who had medial calcaneal neuropathy. From them, unobtainable medial calcaneal nerve response was present in 10 (37.03%) heels of nine (39.13%) patients. Medial calcaneal neuropathy was the solitary cause of chronic plantar heel pain in 10 (37.03%) heels from 10 (43.48%) patients. However, it was associated with other local heel pathologies in the remaining patients. The majority of them were having plantar fasciitis in nine (33.34%) heels from five (21.73%) patients.ConclusionMedial calcaneal neuropathy is present in a considerable number of patients with chronic plantar heel pain. It should be taken into consideration during the assessment of any patient with chronic plantar heel pain.
Highlights
Medial calcaneal neuropathy had been implicated as a source of chronic plantar heel pain
Medial calcaneal neuropathy is considered to be a form of tarsal tunnel syndrome (TTS), when it occurs solitary and is not associated with medial or lateral plantar neuropathies [3,4,5]
The aim of this study was to determine the presence of medial calcaneal neuropathy as a cause of chronic plantar heel pain

Aim The aim was to determine the presence of medial calcaneal neuropathy as a cause of chronic plantar heel pain.

Medial calcaneal neuropathy was the solitary cause of chronic plantar heel pain in 10 (37.03%) heels from 10 (43.48%) patients. It was associated with other local heel pathologies in the remaining patients. The MCN provides sensory innervation to the inferior, medial, and posterior aspects of the heel and the calcaneus [8]
