First Ray

The medial cuneiforms and first metatarsals were identified in 515 randomly selected specimens at the Hamman-Todd osteology collection in the Cleveland Museum of Natural History in Cleveland, Ohio, and the transverse plane angulation of the hallucal tarsometatarsal joint was determined by direct measurement of the selected bones. Medial cuneiforms were subsequently separated into three categories corresponding to the amount of measured obliquity. The first tarsometatarsal joint was reassembled, and the paired medial cuneiforms and first metatarsals were radiographed at different declination angles in inverted, everted, and rectus positions. Radiographic evaluation revealed discordance between the appearance of atavism and true atavism in the cuneiform. Specifically, it was determined that the position of the hallucal tarsometatarsal joint significantly influenced the appearance of atavism in the cuneiform. It is concluded that the position of the first ray in an anteroposterior radiograph can produce the appearance of an increased obliquity angle of the medial cuneiform, resulting in an inaccurate representation of the hallucal tarsometatarsal joint.

Purpose. The Anatomic Fiber Metal plus stem (Zimmer) is one of the anatomically designed cementless stems to achieve stable fixation by metaphyseal fit. We studied outcomes of cementless total hip arthroplasty using this stem and possible effects of metaphyseal fit on outcomes.Methods. The cementless total hip arthroplasty using this stem was performed for 155 hips. One hundred and thirty-seven hips of 122 patients were followed for 5 to 16 (mean, 9.7) years and entered into the study. The metaphyseal fit was defined as good or poor in an anteroposterior radiograph after surgery. We studied the fixation of the stem and bone reaction on an anteroposterior radiograph at the final followup.Results. Twelve hips had revision, six acetabular components and six acetabular liners. No stem was revised. The biological fixation of the stem was bone ingrown fixation for 136 hips and unstable for one. The metaphyseal fit was good for 83 hips and poor for 54 hips. There were no differences for stem fixation and bone reaction between the two groups.Conclusions. The fixation of the stem was stable at a mean followup of 9.7 years independently from metaphyseal fit.
