Total Knee Arthroplasty Outcomes in Patients with Medicare, Medicare Advantage, and Commercial Insurance.

As more commercial insurance companies adopt a bundled reimbursement model, similar to the Comprehensive Care for Joint Replacement (CJR) algorithm for Medicare beneficiaries, accurate risk adjustment of patient-reported outcomes (PROs) is critical to ensure success. With this movement toward bundled reimbursement, it is unknown if a formula adjusting for similar risks in the Medicare population could be applied to PROs in commercially insured and Medicare Advantage populations undergoing total knee arthroplasty (TKA). This study was performed to compare PROs after TKA in these insurance groups after adjusting for proposed risks.

Right Ring Finger Volar Mass in a 14-Year-Old Boy.

A trigger digit is relatively uncommon in adolescents and often has a different etiology in that age group vs adults. In the pediatric population, trigger digits frequently arise from a variety of underlying anatomic situations, including thickening of the flexor digitorum superficialis or flexor digitorum profundus tendons, an abnormal relationship between the flexor digitorum superficialis and flexor digitorum profundus tendons, a proximal flexor digitorum superficialis decussation, or constriction of the pulleys. In addition, underlying conditions such as mucopolysaccharidosis, juvenile rheumatoid arthritis, Ehlers-Danlos syndrome, and central nervous system disorders such as delayed motor development have been associated with triggering.

Correlation of Pelvic and Spinal Parameters in Adult Deformity Patients With Neutral Sagittal Balance.

Study Design: Retrospective measurement of spinal and pelvic parameters in adult spinal deformity patients.

Objective: To correlate spinal and pelvic parameters in adult spinal deformity patients who were in neutral spinal balance.

Summary And Background Data: It is believed that sagittal spinal balance is influenced by both spinal and pelvic parameters, which are closely interrelated as manifested by the reciprocal changes seen when any of the interrelationships was altered.

Assessment of a multibeam Fizeau wedge interferometer for Doppler wind lidar.

The Fabry-Perot interferometer is the standard instrument for the direct detection Doppler lidar measurement of atmospheric wind speeds. The multibeam Fizeau wedge has some practical advantages over the Fabry-Perot, such as the linear fringe pattern, and is evaluated for this application. The optimal Fizeau must have a resolving power of 10(6) or more.
