Use of an Irrigation Pump System in Arthroscopic Procedures.

Since its inception, arthroscopic surgery has become widely adopted among orthopedic surgeons. It is therefore important to have an understanding of the basic principles of arthroscopy. Compared with open techniques, arthroscopic procedures are associated with smaller incisions, less structural damage, improved intra-articular visualization, less pain in the immediate postoperative period, and faster recovery for patients.

Local application of free antibiotic powder in the treatment of osteomyelitis in a rat model.

To date, several strategies have been developed to provide local antibiotic therapy in the treatment of osteomyelitis, such as antibiotic-loaded bone cement, antibiotic-impregnated collagen sponges, polymethylmethacrylate beads, antibiotic-loaded bone graft, antibiotic-loaded synthetic bone substitutes, and antibiotic-coated implants. The optimum carrier for local antibiotic therapy has not been identified. Tibial osteomyelitis using methicillin-sensitive Staphylococcus aureus was created in a rat model.

Submuscular bridge plating for complex pediatric femur fractures is reliable.

Background: Complex, high-energy pediatric femur diaphyseal fractures cannot be treated reliably by conventional methods: casting is not suitable for polytrauma and large children, external fixation is associated with a high rate of malalignment and refractures, elastic nails are unsuitable for unstable fractures and metaphyseal areas, and lateral trochanteric entry rigid nails cannot address proximal and distal fragments and need relatively large medullary canals. A few centers have reported that submuscular bridge plating (SBP) is associated with minimal complications, but these findings require confirmation.

Questions/purposes: We asked whether SBP (1) reproducibly leads to union in unstable fractures with a low complication rate, (2) leads to reasonable alignment and leg length equality (3), is unaffected by age, weight, or location of fracture, and (4) is associated with no or minimal refracture after hardware removal.

Combat wounds in Iraq and Afghanistan from 2005 to 2009.

Background: There have been no large cohort studies examining the wounding patterns and injury mechanisms in Iraq and Afghanistan from 2005 to 2009. This investigation sought to characterize the incidence and epidemiology of combat-related injuries for this period.

Methods: Using the Joint Theater Trauma Registry, a detailed description of the combat casualty care statistics, distribution of wounds, and injury mechanisms sustained by all US service members for wounds (DRG International Classification of Diseases-9th Rev.

Outcomes after spine surgery among racial/ethnic minorities: a meta-analysis of the literature.

Background Context: Prior research has identified disparities in access to care, resource utilization, and outcomes in members of racial and ethnic minorities. However, the role that race/ethnicity may play in influencing outcomes after spine surgery has not been previously studied.

Purpose: To characterize the effect of race and ethnicity on outcome after spine surgery.

Effects of supplemental oxygen and hyperbaric oxygen on tendon healing in a rat model.

Systemic supplemental oxygen therapy (SOT) and hyperbaric oxygen therapy (HBOT) have been shown to positively impact wound healing. The purpose of this study was to evaluate the effects of SOT and HBOT on tendon healing in a rat tendon model. The right patellar tendon of 90 male Sprague-Dawley rats was completely sectioned.

Radiographic evaluation of the modified Brunelli technique versus the Blatt capsulodesis for scapholunate dissociation in a cadaver model.

Purpose: A variety of soft tissue surgical procedures have been developed for treatment of scapholunate (SL) dissociation. The purpose of this study was to compare the degree of correction obtained (as measured on preoperative and postoperative radiographs) when performing the modified Brunelli technique (MBT) with that of the more commonly performed Blatt capsulodesis (BC) and to evaluate each technique after simulated wrist motion.

Methods: Five cadaver wrists were used for this study.

Comparison of operative times between pressure and flow-control pump versus pressure-control pump for ACL reconstruction.

Evidence suggests that a pressure and flow-control pump provides better visualization than a pressure-control pump alone. Increased visualization may lead to decreased operative time. We sought to perform a direct comparison in terms of operative times in anterior cruciate ligament (ACL) reconstructive surgery using these 2 automated pump systems.
