With variation in glenoid design focused mainly on the backside interface of the component with the glenoid bone, keeled and pegged glenoid components have become the basis for most implants. Keeled implants offer a single, deep anchor for the component, while pegged implants offer stability with less bone removal. There is a trend in multiple studies for decreased radiolucent lines, decreased loosening, and decreased revision rates with pegged components. In-line pegs confer several advantages over out-of-line pegs. Advancements in cementing techniques and glenoid preparation have improved longevity for all types of glenoid implants. 相似文献

Significantly displaced intra-articular glenoid fractures treated nonoperatively have been found to have poor functional outcomes. For this reason, most are treated with open reduction and internal fixation. Conventional open techniques involve extensive exposure and soft tissue dissection. Moreover, visualization of the fracture and its reduction can also be difficult even with standard open techniques. We present a case of an Ideberg type III glenoid fracture treated with an arthroscopically assisted percutaneous screw fixation, using the coracoid as a reduction aide. This reduction technique is not previously reported in the literature. Arthroscopically assisted percutaneous glenoid fixation has showed promising early results in the literature. In our case, the fracture united and the patient returned to all his normal daily activities by 7 weeks postoperatively. This suggests arthroscopically assisted glenoid fixation provides good functional and radiological outcomes, without the need for extensive soft tissue dissection. 相似文献
