Comparative StudyFulfillment of patients' expectations for total hip arthroplasty.
Fulfillment of patient expectations is an important outcome of total hip arthroplasty. The objective of the present study was to determine the proportion of expectations that were fulfilled following total hip arthroplasty as well as how the fulfillment of expectations relates to patient and clinical characteristics. ⋯ A better postoperative Lower Limb Core score was most closely associated with the fulfillment of expectations following total hip arthroplasty. Not having a postoperative limp was independent of the postoperative Lower Limb Core score, indicating that the impact of a limp is greater than its manifestation as a physical disability. Better preoperative status also was an independent predictor, indicating that patient expectations are more likely to be fulfilled if the patient is not the most severely impaired at the time of surgery.

Total hip arthroplasty with shortening subtrochanteric osteotomy in Crowe type-IV developmental dysplasia.
When surgeons perform total hip arthroplasty for hips with a high dislocation related to developmental dysplasia of the hip, obtaining long-term stable implant fixation and optimizing patient function remain challenges. The purpose of this paper was to evaluate the results of cementless arthroplasty with a simultaneous subtrochanteric shortening osteotomy in a group of patients with Crowe type-IV developmental dysplasia of the hip. ⋯ Cementless total hip arthroplasty combined with a subtrochanteric femoral shortening osteotomy in patients with a high hip dislocation secondary to developmental dysplasia was associated with high rates of successful fixation of the implants and healing of the osteotomy site and a mean postoperative Harris hip score of 89 points. The complication rate, however, was substantially higher than that associated with primary total hip arthroplasty in patients with degenerative arthritis.

Relationship of the anterior humeral line to the capitellar ossific nucleus: variability with age.
The anterior humeral line is used to assess displacement and the adequacy of reduction of supracondylar humeral fractures in children. It is said to pass through the middle third of the capitellum in the elbow of a normal child. Few reports in the published literature have discussed this measurement, and the intra-rater and inter-rater reliability of the measurement is not known. The purposes of the present study were to define the position of the anterior humeral line in normal, skeletally immature elbows and to determine the intra-rater and inter-rater reliability of this parameter. ⋯ The anterior humeral line passes through the middle third of the capitellum in the majority of normal children. In children younger than four years of age, it passes nearly equally through the anterior or middle third of the capitellum, whereas in older children it more consistently passes through the middle third of the capitellum. The surgeon must be aware of the variability of the location of the anterior humeral line with age when utilizing it to assess radiographs of the elbow in children after an injury or after the reduction of a displaced supracondylar fracture.
