Bone fractures and treatments

Pes plano-valgus staticus juvenilis designates the growing foot that shows the typical distortions when loaded but is of normal clinical and roentgenological appearance when unloaded-at least in the early stage of the condition. It is the commonest type of pes plano-valgus and the commonest deformity of the foot. Owing to this frequency of the disease and the secondary pathological changes occurring later in life, the condition often represents a considerable medical and social problem. The primary cause of the deformity is still obscure. Most authors believe it to be a disproportion between the strength of the muscles and ligaments of the feet and the weight to be carried (Bardenheuer 1910, Brinkmann 1939, Milch 1942). Since the condition is so common, some authors believe it might be due to constitutional weakness of these structures (Miller 1927, Hohmann 1951 and others). This line of thought is supported by the familial occurrence of the disease, which was also seen in the present material (vide infra) . Niederecker (1950, 1959) stressed the r81e of muscle anomalies in the causation of the condition and discusses a statically unfavourable insertion of the musc. tibialis anterior and musc. peroneus tertius as well as the occurrence of a musc. peroneus quartus. Other authors, such as Hoke (1931), suggest the possibility of muscle incoordination as an etiological factor. Timmer ( 19241, Erlacher (1942) believe the cause to be a congenital pes calcaneo-valgus. Wetzenstein (1960) expresses a similar line of thought. Bohm (1930) suggests inhibition of the normal development of the ankle joint, Harris & Beath (1948) speak of congenital anomaly of talus and calcaneus while Strackcr (1953) believes neurogenic factors to be responsible.
