ORIF versus arthroplasty for open proximal humerus fractures: Nationwide Inpatient Sample data between 1998 and 2013.

Background: Limited data exists in analyzing open reduction and internal fixation (ORIF) and arthroplasty in the management of open proximal humerus fractures. We analyzed differences in hospital course between these procedures, patient demographics, complication rate, length of stay, hospital charges, and mortality rate.

Materials And Methods: This is a retrospective review of the Nationwide Inpatient Sample database.

A Biomechanical Comparison of Different Tendon Repair Techniques.

Previous studies have examined multiple suture techniques for the repair of ruptured tendons. In this study, we investigated how the two- and four-stranded Krackow suture weave techniques compared with a novel Krackow/Bunnell suture technique. Our hypothesis was that the Krackow/Bunnell suture would have greater strength compared with the two- and four-stranded Krackow suture in terms of resistance to pullout from the muscle tendon.

Multimodality treatment of a multifocal osteoblastoma-like tumor of the lower extremity.

Osteoblastoma-like tumor is a rare condition with limited information on its orthopedic management in the current medical literature. The tumor histologically resembles an osteoblastoma, although the radiographic features are similar to those observed in primary vascular lesions. The treatment in the previously reported cases involved aggressive procedures including amputation, en bloc resection, and chemotherapy because of the uncertainty regarding the biological behavior of the tumor.

Performance-based tests and self-reported questionnaires provide distinct information for the preoperative evaluation of total hip arthroplasty patients.

Our objectives were to assess relationships between self-reported questionnaires and 2-minute walk test (2MWT) and timed get-up-and-go test (TUG) in preoperative total hip arthroplasty patients. A total of 162 patients completed the Western Ontario and McMaster Universities Osteoarthritis Index and Short Form 36 and performed 2MWT and TUG. Correlations between self-reported questionnaires and 2MWT and TUG were mild to moderate, indicating that the 2MWT and TUG capture additional dimensions of preoperative total hip arthroplasty function not measured by the Western Ontario and McMaster Universities Osteoarthritis Index and Short Form 36.

Low bone mineral density in adolescents with beta-thalassemia.

The pervasiveness of low bone mass (LBM) in beta-thalassemia (Thal) patients (pts) is escalating as the average life expectancy of these pts increases. Adolescence is a period of substantial bone accrual, which is crucial for future bone strength. Studies of LBM are prevalent among adults with Thal.
