Bilateral hypoplastic calcanei.

Abstract

A previously undescribed anomaly of the calcaneus occurred in an otherwise healthy 2-month-old girl. There was marked bilateral hypoplasia of the calcanei, involving approximately the posterior half of each. The child stood at 15 months and walked at 22 months. At age 5 years, the child had a slight in-toed gait that corrected with dorsiflexion. Her only problem has been some difficulty with shoeware. The etiology of this anomaly remains conjectural.

Medial calcaneal neuropathy is associated with plantar fasciitis.

OBJECTIVE: To demonstrate a method of sensory nerve conduction study (NCS) for the medial calcaneal nerve (MCN) and confirm the medial calcaneal neuropathy in patients with plantar fasciitis (PF). METHODS: Twenty-six patients with clinical and ultrasonographic diagnosis of PF participated in the present study. An antidromic method for sensory NCS of MCN was performed in each patient and in 30 controls. The conduction latency, sensory nerve conduction velocity (SNCV) and amplitude of the sensory nerve action potential (SNAP) were measured and the correlation of the SNCV of MCN with both body weight and body mass index (BMI) was studied. RESULTS: The mean conduction latency obtained in the MCN was greater in the PF patients than in the normal controls. Mean SNCV and SNAP amplitude of the MCN were significantly less in the PF patients than in the normal controls. Body weight and BMI were greater in PF patients than in controls. Six patients were identified as having a medial calcaneal neuropathy by using the criteria of the lowest normal values of the NCS of MCN from the normal controls. CONCLUSIONS: Medial calcaneal neuropathy is associated with PF. The present method of sensory NCS is useful and objective in the diagnosis of the medial calcaneal neuropathy. SIGNIFICANCE: Medial calcaneal neuropathy was confirmed by the sensory NCS of MCN and shown to be associated with PF.

Radiographic diagnosis of posterior facet talocalcaneal coalition.

Tarsal coalition is a relatively common segmentation abnormality of the hindfoot that can result in foot and ankle pain in both adolescents and adults. The most common types are calcaneonavicular and talocalcaneal. Posterior subtalar facet coalition is less common. We present a 10-year-old boy with a history of chronic left ankle and foot pain. Radiographs demonstrated calcaneal "humpback" sign, representing the posterior subtalar bony coalition, and CT demonstrated in more detail the extent of bony and fibrous coalition. These findings led to surgical intervention.

Role of computerised tomography in management of intra-articular fractures of the os calcis.

This study aimed to look at the role played by the CT scan in decision making in the management of intra-articular fractures of the calcaneum. Twenty-four patients with intra-articular fractures of the calcaneum were included. Their initial radiographs and CT films were blinded and assessed by three independent observers. Based on this they were selected for operative or non-operative management. The actual management was also recorded. The data were then subjected to statistical analysis to look at the association between the decision from radiograph, that from the CT scan and the actual management undertaken. Non-parametric tests for related samples were performed to look at the association between the actual management and the decisions made by assessing the radiographs and the CT scans. For all three observers, there was no significant difference between the actual management and decisions made by assessing the plain radiographs or the CT scan. There was also no significant difference between the radiograph-based and the CT-based decisions. However, the Cochran Q test showed that there was significant variation among the three observers for the CT-based assessment. Our results, show that the CT scan should only be done when a definite decision is made to operate on a patient, based on plain radiographs. Calcaneal fractures which are selected for non-operative management, based on X rays, should not have a CT scan as a routine as it provides no valuable additional information affecting the management decision.
