BACKGROUND Preoperative risk assessment is important yet inexact in older patients because physiologic reserves are difficult to measure. Frailty is thought to estimate physiologic reserves, although its use has not been evaluated in surgical patients. We designed a study to determine if frailty predicts surgical complications and enhances current(More)
STUDY DESIGN Multicenter, retrospective, nonrandomized comparison group study of patients with severe scoliosis and kyphosis treated after 1995 with halo-gravity traction and without halo-gravity traction before definitive fusion. OBJECTIVE Compare surgical correction of severe spine deformity with preoperative halo traction and without preoperative(More)
BACKGROUND The durability of total hip arthroplasty in younger patients has been reported to be less than that in older patients. The purpose of this study was to evaluate the results of cementless total hip arthroplasty performed in a consecutive series of patients fifty years of age or younger who were followed for a minimum of ten years.

Chondromyxoid fibroma is a rare cartilage tumor that represents less than 1% of all bone tumors. When in a long bone, it is usually an intramedullary lesion that is eccentrically located in the metaphyseal region. Chondromyxoid fibroma may also have unusual presentations. These include intracortical lesions and subperiosteal lesions. There have been 14(More)
BACKGROUND There is a paucity of literature concerning functional assessment at long-term followup of THAs in general and in young patients specifically. Functional data may be useful in determining differences in the performance of various implants and surgical techniques in THA. QUESTIONS/PURPOSES The purposes of this study were to evaluate a group of(More)
