Calcaneal Pitch and Lateral Talocalcaneal Angle among Nigerians

Radiographs have been used as tools of diagnosis, prognosis and in selection and evaluation of treatment modalities of various types of deformities and fractures of the foot (Katz et al., 1997; Igbibi & Mutesasira, 2003; Dooley et al., 2004; Dobbs et al., 2006; Westberry et al., 2007; Aminian & Sangeorzan, 2008; Radler et al., 2010). Lateral talocalcaneal angle (L TCA) is an angle formed by a line along the long axis of the talus and another line along the long axis of the calcaneus on a standard weight bearing lateral radiograph of the foot. The angle is used widely in the diagnosis and choice of treatment modalities for club foot. It is also widely used in assessing hind foot valgus (Westberry et al.; Anad & Sala, 2008), in assessment of treatment outcomes for planovalgus deformities (Knupp et al., 2009); assessment of treatment outcomes for sequelae of fractures of the calcaneus (Savva & Saxby, 2007) and other forms of calcaneus deformity and club foot (Wisbrun, 1932; Aronson et al., 1983; Davids et al., 2007).
