Comparative Study
Impact of Age, Gender and Anesthesia Modality on Post-Operative Pain in Total Knee Arthroplasty Patients.
Optimizing pain control following total knee arthroplasty is of utmost importance to the immediate post-operative course. Various anesthesia modalities are available, but studies comparing multiple anesthesia modalities, patient age, and sex are limited. ⋯ Level III, Therapeutic Study, (Retrospective Comparative study).

Risk Factors for Nonroutine Discharge in Patients Undergoing Spinal Fusion for Intervertebral Disc Disorders.
Although outcomes following spinal fusion for intervertebral disc disorders have been studied, factors influencing discharge disposition and health care resource utilization have not been determined. This study sought to clarify perioperative risk factors for non-routine discharge and prolonged hospital stay in patients undergoing fusion for intervertebral disc disorders. ⋯ 3.

Expedited Operative Care of Hip Fractures Results in Significantly Lower Cost of Treatment.
There are an estimated 150,000 hip fractures per year in the United States, with estimated costs of care between $10.3 billion and $15.2 billion. With such high costs and an increasing burden of care, there has been interest in newer methods to increase efficiency of care. One such method is expedited fracture care, with earlier operative intervention. The purpose of this study was to determine if intervention within six hours of admission decreased costs with no change in the rate of major complications. ⋯ Level IV, therapeutic case series.

Comparative Study
Assessment of SiCaP-30 in a Rabbit Posterolateral Fusion Model with Concurrent Chemotherapy.
Chemotherapy derivatives of the rabbit posterolateral fusion model are considered a challenging environment in which to test bone graft materials. The purpose of this study was to determine the performance characteristics of SiCaP-30 as a bone graft substitute relative to autograft (iliac crest bone graft [ICBG]), Actifuse ABX and β-Tricalcium Phosphate-Bioactive Glass-Type I Collagen (βTCP-BG) in a rabbit posterolateral spine fusion model with concurrent chemotherapy treatment This was a randomized, controlled study in a laboratory setting with blinded assessment of fusion by manual palpation and flexibility testing. Sixty rabbits were entered into the study with 45 used for analysis. ⋯ The Actifuse ABX group had a 33% (4/12) manual palpation fusion rate and a motion analysis fusion rate of 25% (3/12). No motion segments in the Vitoss BA group (0/11) showed any signs of fusion. The SiCaP-30 group demonstrated a statistically higher manual palpation and motion analysis fusion rate of 82% (9/11; p<0.05) and produced superior bone formation compared with Actifuse ABX and βTCP-BG.

Fracture of the scaphoid bone can be treated with cast immobilization or surgery. Historically, surgery was reserved for displaced fractures. However, because weeks of cast immobilization may result in stiffness, loss of strength, loss of bone density and an inability to work or participate in recreational activities for a prolonged period, operative treatment of non-displaced fractures has become increasingly common. Several surgical techniques for fixation have been described, but their risks and benefits have not yet been clearly elucidated. In a study in cadavers, we investigated whether one approach--volar percutaneous fixation--might pose a risk of injury to surrounding structures. ⋯ Our findings indicate that modification of the volar percutaneous approach to scaphoid fixation may be advisable to avoid damage to adjacent structures. We suggest use of a "mini-open" percutaneous procedure.
