Standardizing methods of measurement of foot shape by including the effects of subtalar rotation.

At the present time, there is no easily performed method of measuring foot shape that can quantitatively differentiate types of feet. We studied 44 feet of individuals with normal appearing asymptomatic feet and flat symptomatic feet to find criteria for measurement of foot shape. We found that measurements of footprints are unreliable. Radiographic methods must include measurements in different positions, or at least specify the position of subtalar rotation to be meaningful, since the height of the arch can change just by rotating the tibia. Traditional measurements of talocalcaneal angles have no precision and are unreproducible.

Indicators of recovery from fractures of the hip.

Patients with similar injuries who were at a similar level of function before the injury differ in the extent of recovery. In an attempt to identify important factors that affect recovery, we collected extensive physical, psychological and sociological data on a group of 108 elderly people with fractures of the hip in order to study the influence of the many variables on their recovery. We found that of all the items studied, those that best indicated the degree of recovery were: (1) the physical therapist's rating of functional ability; (2) how often the patient got outside the home prior to injury; (3) the patient's mental clarity.

Posterior roentgenogram of the foot.

A present there is no reliable way to define the position of the heel in relationship to the tibia during weight bearing. Many surgical and nonsurgical procedures are done to correct a varus or valgus heel without a standard method to define the problem or measure the results. This is a report on a posterior roentgenographic technique which defines the position of the heel with respect to the talus, tibia, and forefoot. This technique allows for measurement of the position of the heel and can be performed in any X-ray facility.
