To test the hypothesis that the reproducibility of radiographic measurements of the first metatarsophalangeal angle and the intermetatarsal angle I-II can be increased by exact guidelines, we calculated the intra- and interobserver reliability of both methods. 4 independent observers (2 senior residents and 2 orthopedic trainees) evaluated 50 pre- and 50 postoperative plain dorsoplantar radiographs with their method of preference and then with Mitchell et al.'s method (1958). The mean intraobserver coefficient of repeatability for the metatarsophalangeal angle improved from 5.9 degrees to 4.2 degrees and for the intermetatarsal angle I-II, from 4.4 degrees to 2.8 degrees. The interobserver coefficient of repeatability improved from 6.5 degrees to 5.0 degrees for the metatarsophalangeal angle, and from 4.9 degrees to 3.6 degrees for the intermetatarsal angle I-II. This improvement in measurement accuracy was more marked for postoperative measurements, due to deformation of the metatarsal after the osteotomy which made it more difficult to find the longitudinal axis of the metatarsal. The improvements in the accuracy of measurements were also greater in the two inexperienced observers, since their measurements differed more when they had no exact guidelines for their drawings.

Background: Roberts syndrome (Pseudothalidomide) is a rare birth defect that causes severe bone malformation complex. The bones of the arms, and in some cases other appendages, may be extremely shortened and even absent. The fingers of the hands may be fused. An extreme case results in the absence of the upper bones of both the arms and legs so that the hands and feet appear attached directly to the body. This is called tetraphocomelia.

Introduction: Expressionless face associated with multiple contractures has been encountered in an infant. There is a wide range of misconception regarding the categorization of children with multiple contractures among different pediatric disciplines. The fundamental element in categorizing children with multiple contractures is "the etiological understanding". In the absence of concomitant neuromuscular disease, however, the search for other reasons is mandatory. Our present paper signifies the necessity of proper interpretations of unusual clinical and radiographic features.
