AI Article Synopsis
- Glenoid deformity significantly impacts the success and complication rates of shoulder arthroplasty in patients with primary glenohumeral arthritis.
- The B2/B3 types of glenoid deformities are particularly linked to worse outcomes after surgery compared to other types.
- The review aims to offer evidence-based strategies for effectively managing glenoid deformity during shoulder arthroplasty, balancing the correction of deformity with the preservation of the joint line.
Article Abstract
Glenoid deformity has an important effect on outcomes and complication rates after shoulder arthroplasty for primary glenohumeral arthritis. The B2/B3 glenoid has particularly been associated with a poorer outcome with shoulder arthroplasty compared with other glenoid types. One of the primary challenges is striking a balance between deformity correction and joint line preservation. Recently, there has been a proliferation of both anatomic and reverse implants that may be used to address glenoid deformity. The purpose of this review was to provide an evidence-based approach for addressing glenoid deformity associated with primary glenohumeral arthritis.

Article Synopsis
- The optimal treatment for B2 glenoid morphology in young, active osteoarthritis patients is debated, with various options like hemiarthroplasty, total shoulder arthroplasty (TSA), and reverse TSA available, each having pros and cons.
- Eccentric glenoid reaming can be effective but risks damaging the bone structure, potentially complicating future surgeries, while bone grafting, though beneficial for some, comes with high complication rates.
- Reverse TSA offers a more stable alternative when correcting version and inclination proves difficult, as it adapts better to glenoid deformities and maintains functionality with reduced bone stock.
The Role of Inlay and Inset Glenoid Implants in Anatomic Total Shoulder Arthroplasty.

Anatomic total shoulder arthroplasty is an established treatment for degenerative conditions involving the shoulder. One well-described complication of total shoulder arthroplasty is glenoid loosening, especially in younger and more active patients. As a result, several surgeons recommend against activities that may put patients at risk of implant failure after shoulder arthroplasty.

Background: Avoiding inclination of the glenoid baseplate in reverse shoulder arthroplasty often requires considerable glenoid reaming. It is proposed that the use of a metal wedged baseplate in all patients can achieve neutral inclination with reduced glenoid reaming.
Materials And Methods: A prospective clinical single-centre study with minimum two-year follow-up was carried out.
Biomechanical effects of functional clear aligners on the stomatognathic system in teens with class II malocclusion: a new model through finite element analysis.

Objectives: The Functional Clear Aligner (FCA) is a novel orthodontic appliance designed for the treatment of Class II malocclusion with mandibular retrognathia in adolescents. The aim of this study was to investigate the biomechanical characteristics of the masticatory muscles, jawbone, and temporomandibular joint (TMJ) during mandibular advancement using either FCA or Class II elastics combined with clear aligner (Class II elastics) through finite element analysis.
Materials And Methods: A 3D finite element model of the 'muscle-jawbone-TMJ-appliance' system was constructed based on CBCT and MRI images of a boy with skeletal Class II malocclusion.

Article Synopsis
- * Thirteen lame horses were analyzed using standing magnetic resonance imaging (sMRI) to detect signs of subchondral and trabecular bone injuries, primarily located on the medial aspect of the P1 glenoid, with various noted changes.
- * Follow-up imaging revealed worsening conditions in some horses, with one case ultimately resulting in a comminuted fracture, suggesting that the observed bone injuries are indicative of chronic overload and potential incomplete stress fractures.
