One hundred feet in 50 children between the ages of 3 and 9 years with a diagnosis of idiopathic hypermobile flatfoot had a custom-molded insert ordered. A specific method of casting, correcting the various components of the deformity was utilized. An 1/8-inch polypropolene insert was fabricated from the positive cast. The insert was worn in leather shoes with a long counter, steel shank, and Thomas heel. The flatfoot was evaluated and classified by measurement of the talometatarsal angle on a standing lateral X-ray. The insert was fabricated so that the standing lateral talometatarsal angle was corrected to neutral with the insert on the foot and the foot in the shoe. The preliminary reports indicate that a correction can be obtained at the rate of 0.41 degrees per month or approximately 5 degrees per year. There was no significant loss of motion of the foot or the ankle. Perhaps this regimen may be utilized in those children with a hypermobile flatfoot for whom treatment is advised.

A 27-year-old man with a high-energy, open-fracture dislocation of the ankle underwent debridement and open reduction of his injuries. During surgery a disruption-laceration of the posterior tibial tendon at the level of the fracture of the medial malleolus was found. Repair required location of the proximal muscle and tendon and controlled traction of the musculotendinous unit from its retracted position. Common aspects in the nine previously reported instances of this lesion include relatively high energy of the injury and the fracture type, a transverse fracture in the medial malleolus. Unique to this case was the open injury.
