Imaging of the B2 Glenoid: An Assessment of Glenoid Wear
2019年7月9日 · The B2 glenoid (Figure 2) is characterized by biconcavity on the glenoid surface where the native anterior glenoid or paleoglenoid persists and represents preserved premorbid anterior glenoid fossa, while varying amounts of posterior glenoid bone loss occur in association with humeral head translation posteriorly. As the humeral head ...
Surgical management of the biconcave (B2) glenoid - PMC
The biconcave (B2) glenoid is characterized by a normal anterior glenoid (paleoglenoid) that represents the native glenoid fossa and varying amounts of posterior bone loss. The humeral head translates posteriorly to articulate with the new posterior concavity (neoglenoid).
The B2 glenoid challenges the shoulder arthroplasty surgeon who must correct the sub- stantial deformity to provide a well-functioning and lasting anatomic total shoulder arthroplasty.
The biconcave (B2) glenoid is characterized by asymmetric posterior bone loss and a posterior translated humeral head that is seated in a bicon-cave glenoid. The degree and extent of bone loss in the B2 glenoid can be highly variable, ranging from the classic interpretation, in which 50% of the native glenoid fossa is preserved, to the more

terns. The type B2 glenoid is characterized by the creation of a biconcave glenoid due to eccentric posterior erosion and posterior humeral subluxation. The Walch classifica-tion was later updated to include type B3, which is defined as severe posterior erosion leading to a mono-concave glenoid with at least 15 of retroversion or 70% posterior

Walch B2 glenoids: 2-dimensional vs 3-dimensional comparison of …
2022年2月11日 · The humeral head posterior subluxation in Walch B2 glenoid was significantly greater in 3D with Glenosys software than 2D manual assessment. The 2D measures were systematically different from 3D ones by a mean of −9.3%. The 2D and 3D subluxations showed a mild positive correlation.
These characteristics that are associated with the B2 glenoid can be surgically managed in several ways, including arthroscopic debride-ment, hemiarthroplasty, anatomic total shoulder arthroplasty (TSA) with eccentric reaming, bone grafting, augmented glenoid implants, and reverse TSA (RTSA).
