BACKGROUND The treatment of comminuted radial head fractures can include prosthetic replacement or open reduction and internal fixation. The purpose of this study is to evaluate the results of two different internal fixation systems for Mason type II-III radial head fractures. METHODS Between 2005 and 2015, 82 patients were treated using pins and 65 patients by mini-screws. The follow-up prot...

BACKGROUND Osteochondral injuries, if not treated appropriately, often lead to severe osteoarthritis of the affected joint. Without refixation of the osteochondral fragment, human cartilage only repairs these defects imperfectly. All existing refixation systems for chondral defects have disadvantages, for instance bad MRI quality in the postoperative follow-up or low anchoring forces. To addres...

PURPOSE To compare the use of the distal anterolateral accessory (DALA) portal with the anterolateral (AL) and midanterior (MA) portals during arthroscopic hip labral repair. METHODS Standard AL, MA, and DALA portals were created on 6 cadaveric hip specimens. Four 2.4-mm pins were placed in the acetabular rim to the depth of a standard anchor using a drill guide. Pins were placed in the 12 to...

Abstract Context Evidence has shown that spinal mobilization with leg movement (SMWLM) and progressive inhibition of neuromuscular structures (PINS) are individually effective in the management lumbar radiculopathy. However, previous evidence reported data for only a short-term study period did not investigate effect combined manual therapy techniques. Objectives To compare effects two techniqu...

Foreign body migration into the vasculature and subsequent embolization is a rare complication of both medical procedures and penetrating trauma. Endovascular filters, wires, and pins have been found to travel through the vasculature resulting in a variety of complications, including death [1]. In the case of penetrating trauma, the incidence of bullet migration into the vasculature is approxim...

DRAMs contain a very wide datapath internal to the chip which can deliver orders of magnitude greater memory bandwidth inside the chip than through the pins. The dilemma lies in deciding what to connect to the other end of this wide pipe to memory. We compare two alternatives: microprocessors (including MIMD multiprocessors) and SIMD processors. Microprocessors are better accepted and are suite...
