“…The finding of glenoid inferior inclination on the impaired side is a novel result for the study of children affected by OBPP and is supported by a similar finding in a recent rat study . Studies focused on adult shoulder pathology have frequently evaluated both glenoid version and inclination . One of the key findings of these studies is that superior glenoid inclination increases the risk of superior humeral head translation .…”

“…20 Studies focused on adult shoulder pathology have frequently evaluated both glenoid version and inclination. [29][30][31][32][33][34] One of the key findings of these studies is that superior glenoid inclination increases the risk of superior humeral head translation. 29,35 This mirrors the findings of the current study, where humeral head inferior translation was shown to be correlated to inferior glenoid inclination.…”

The primary objective of this study was to test the hypothesis that gleno-humeral deformity in children and adolescent with obstetrical brachial plexus palsy is three-dimensional (3D). The study also compared the metrological properties of typical two-dimensional gleno-humeral measures to the newly developed 3D measures. Thirteen individuals (age = 11.8 ± 3.3 years) with obstetrical brachial plexus palsy participated in this IRB-approved study. 3D axial magnetic resonance images were acquired for both shoulders. Glenoid and humeral models were created in order to quantify 3D glenoid version, humeral head migration, and glenoid concavity. Two-dimensional (2D) measures were acquired as recommended in the literature. All measures were completed by two observers in this observer-blind study. Compared to the non-involved side, the glenoid was more retroverted (7.91°, p = 0.003) and inferiorly oriented (7.28°, p = 0.009). The humeral head was migrated more posteriorly (5.54 mm, p = 0.007), inferiorly (−3.96 mm, p = 0.013), and medially (−3.63 mm, p = 0.002). Eleven of the 13 glenoids were concave, based on the 3D glenoid models. The concurrent validity between three-and 2D measures were highly dependent of the parameter measured, the slice level used for the 2D analysis, and the presence/absence of pathology (0.63 3°) was larger than that for the 3D measure of version (<1°) on the involved side. This study clearly demonstrated that the gleno-humeral deformation in obstetrical brachial plexus palsy is 3D, emphasizing the need for 3D subject specific gleno-humeral shape analysis for follow-up and treatment plans in children with obstetrical brachial plexus palsy.

“…Glenoid inclination was defined by the angle formed by the intersection of the transverse axis of the scapula and the plane perpendicular to the face of the glenoid fossa. 10,[16][17][18] Prosthesis inclination was defined as the angle formed between the transverse axis of the scapula and the glenoid baseplate. These measurements are automated in the Glenosys software.…”

Inferior glenoid baseplate tilt relative to the coronal axis of the scapular body has been associated with improved results and fewer postoperative complications in reverse shoulder arthroplasty. However, the native glenoid surface is not always a reliable reference for the true scapular axis. Digital preoperative planning software and advanced imaging now allow surgeons to more precisely determine optimal glenoid placement. The purpose of this study was to evaluate the accuracy of the subchondral smile and cannulated surface guide techniques in achieving inferior glenoid baseplate tilt by using 3-dimensional preoperative planning software. Virtual glenoid baseplate preparation and implantation was performed using computed tomography scans of 16 shoulders with rotator cuff deficiency. Two techniques were used: a subchondral smile technique that preferentially reams the interior glenoid, resulting in the appearance of a smile, and a cannulated surface guide technique that references the native glenoid face to place the baseplate in 10° of inferior tilt. Using the subchondral smile technique, the glenoid baseplate was implanted at a mean of 8.9° of superior tilt relative to the transverse scapular axis. Using the surface guide technique, the glenoid baseplate was implanted at a mean of 2.8° of superior tilt. Neither the subchondral smile technique nor the 10° cannulated surface guide technique is a reliable method to produce inferior glenoid tilt relative to the transverse axis of the scapula. Three-dimensional preoperative planning software is a useful tool when attempting to achieve optimal glenoid baseplate positioning in reverse shoulder arthroplasty.

“…• Use the premorbid glenoid morphology as a patient-specific guide for the selection of the implant and its placement, to reconstruct normal glenoid version and inclination, and to restore the normal premorbid joint line position. Most patients have native glenoid version between 6°and 8°of retroversion 22 . Correcting version to neutral for all patients would lead to overcorrection of pathologic version and unnecessary removal of bone, particularly of the anterior subchondral bone.…”

Is Premorbid Glenoid Anatomy Altered in Patients with Glenohumeral Osteoarthritis?

Abstract: The glenoid vault model may be a clinically useful tool to estimate patient-specific premorbid glenoid anatomy, which may help in preoperative or intraoperative surgical planning for total shoulder arthroplasty.
