Unstable ankle fractures: comparison of closed versus open treatment.
To determine what factors were important in final clinical results, we evaluated 145 patients admitted to Vanderbilt University Hospital with ankle fractures between January 1971 and December 1976. There was a strong correlation between anatomic results of reduction and final clinical results. Talar displacement of more than 5 mm before reduction, a posterior malleolus fracture involving more than 25% of the articular surface, an anterior tibial plafond fracture involving more than 25% of the articular surface, and talus fractures involving the articular surface were four variables which significantly affected results. Open reduction, torn deltoid ligaments, open fractures, type of fracture, type of internal fixation devices used, sex, and age did not signficantly affect results. Other injuries in association with ankle fractures, especially after automobile accidents, frequently prolonged hospitalization.

Isometric muscle contraction response during recovery from reduced intramuscular temperature.
This study was done to determine the effects of a 30-minute cold water bath on intramuscular temperature and plantar flexion strength, immediately after treatment and during a 3-hour posttreatment recovery period. Twenty persons were tested twice, receiving treatment once and serving as controls once. Measurements were taken prior to the treatment period, immediately after treatment and then every 30 minutes for 3 hours. The dominant leg was submerged in water at 10 C for 30 minutes. Plantar flexion strength was measured with a cable tensiometer and intramuscular temperature was measured with a hypodermic thermistor probe. Intramuscular temperature significantly decreased immediately posttreatment on the experimental days and then increased significantly during the recovery period. Significant increases in strength were noted during the recovery period. A definite relationship exists between intramuscular temperature and plantar flexion strength.

Anterior subglenoid dislocation of the shoulder in an infant following pneumococcal meningitis.
A 7 1/2-month-old boy had an anterior inferior dislocation of the shoulder. Dislocations of the shoulder in infants have previously been reported, and were either congenital dislocations with associated anomalies of the glenohumeral joint with dislocations from Erb's palsy or septic arthritis. In the present case, dislocation of the shoulder was associated with spastic brain damage. The marked spasticity of the deltoid muscle may have been the deforming force. Capsular and subscapularis plication plus recession of the deltoid corrected the deformity and prevented further dislocations.

Habitual toe-walkers. A clinical and electromyographic gait analysis.
Six children who were habitual toe-walkers were studied using electromyographic techniques. In the initial gait evaluation, the muscle synergy pattern was found to be abnormal during the toe-toe gait as well as during the heel-toe gait. After treatment with casts, each patient had a normal electromyographic pattern during heel-toe gait.
