Fig. 1 Coronal short tau inversion recovery (STIR) magnetic resonance image acquired with use of metal artifact reduction sequence (MARS), demonstrating a large pseudotumor (arrows) surrounding the prosthetic hip joint, approximately twenty-one months following total hip arthroplasty (Case 3). As a reference, the greater trochanter (GT), modular prosthetic femoral neck (N), and modular femoral head (H) are labeled.

Peak salicylate (SA) level was a good predictor of radiographic healing (area under receiver operating characteristic [ROC] curve = 0.8, 95% confidence interval [CI] = 0.5 to 0.94), with a predicted threshold of 20.7 μg/mL for delayed radiographic healing.

The number of live human mesenchymal stem cells present twenty-four hours after a sixty-minute treatment with 0.9% normal saline solution (Control), 1% and 2% lidocaine (Lido), 0.25% and 0.5% bupivacaine (Bup), and 0.2% and 0.5% ropivacaine (Rop). Three separate experiments were performed in each treatment group. The bar heights represent the least-squares mean of the number of live cells relative to the control, and the error bars represent the standard error of the mean. The results for treatments labeled with different letters (e.g., A and B) differed significantly from each other (p < 0.05), whereas treatments labeled with the same letter did not.

Radiographs of patients diagnosed with atypical femoral fractures. The radiographic features of an atypical femoral fracture include a common location in the subtrochanteric (Fig. 1-A) or femoral shaft region (Fig. 1-B), transverse or short oblique fracture configurations, absence of comminution, a medial spike (asterisks), localized periosteal thickening of the lateral cortex (black arrowheads), and generalized thickening of the femoral cortices (white arrows).

Flowchart showing patient demographic and clinical characteristics of 5333 patients. (Of the original 6779 patients, 643 were excluded for having follow-up [f/u] of less than one month and 803 were excluded for having an incomplete smoking history.) At the time of entry into treatment, the data are given as the mean number of patients, categorized by smoking status, sex, and the mean (and standard deviation) values of age, body mass index (BMI), and the Oswestry Disability Index (ODI).

Computer simulation of deformity correction in a patient with malunited fractures of both bones of the forearm (Case 14). Fig. 1-A The proximal part of the models of the affected bones (solid white) was superimposed on the corresponding part of the mirror image of the contralateral, normal bones (translucent blue). Figs. 1-B and 1-C Corrective osteotomy was simulated with use of the mirror image as the goal model. The pink segments represent the wedges to be removed for closing-wedge osteotomy.
