Purpose: Using a cadaveric model simulating clinical situations experienced during open reduction and internal fixation of proximal phalangeal fractures, the aim of this study was to evaluate the relationship between level of training and the rates of short, long, and ideal screw length selection based on depth gauge use without fluoroscopy assistance.

Methods: A dorsal approach to the proximal phalanx was performed on the index, middle, and ring fingers of 4 cadaveric specimens, and 3 drill holes were placed in each phalanx. Volunteers at different levels of training then measured the drill holes with a depth gauge and selected appropriate screw sizes.

Cable nerve grafting is the recommended surgical treatment for large peripheral nerve defects. Traditionally, this is performed by bridging a gap in the nerve with multiple autologous nerve cables, repairing the epineurium of each cable to the perineurium of a fascicle of the injured nerve that is similar in size to the graft. The authors present a new technique in which they used nerve-cutting guides to aid in the placement of fibrin glue to secure the sides of the cabled nerve graft together to facilitate handling of the cabled nerve graft and to expedite repair.

Background: A recent study from our laboratory has demonstrated improved range of motion in the toes of broiler chickens afflicted with pyogenic flexor tenosynovitis when treated with local antibiotic and corticosteroid injections, without surgical drainage. However, the use of corticosteroids as an adjunct treatment raised peer concern, as steroids are thought to have deleterious effects on tendon strength. The purpose of this study was to compare the tensile strength of the aforementioned steroid treated tendons, to a group of tendons administered with the current standard treatment: systemic antibiotics, surgical drainage and no corticosteroids.

Mechanical stimuli play important roles in proliferation and differentiation of connective tissue cells, and development and homeostatic maintenance of tissues. However, excessive mechanical loading to a tissue can injure cells and disrupt the matrix, as occurs in tendinopathy. Tendinopathy is a common clinical problem in athletes and in many occupational settings due to overuse of the tendon.

Background: Many similarities exist between pyogenic flexor tenosynovitis and other closed-space infections such as septic arthritis. Previous studies have demonstrated that corticosteroids in conjunction with antibiotics considerably improve treatment outcomes in patients with septic arthritis. Using a chicken model, we investigated whether or not corticosteroids in combination with antibiotics and/or surgical drainage could minimize the loss of range of motion typically associated with pyogenic flexor tenosynovitis.

The CRUSADE National Quality Improvement Initiative was created to track national care patterns, facilitate process improvement, and improve patient outcomes among patients with acute coronary syndromes (ACS). CRUSADE found that patients in community practice were sicker than those in randomized clinical trials and often failed to receive evidence-based therapies. Dosing regimens of antithrombotic therapy were also suboptimal, raising safety concerns.

Intra-articular fractures of the second through fifth metacarpal bases are uncommon injuries but can result in serious morbidity if improperly managed. These injuries usually occur because of forced flexion of the wrist with simultaneous extension of the arm, as occurs with a punch or a fall. As there are few large series of reports for these injuries, there is no consensus in the current literature on the most appropriate treatment for them.
