“…A comprehensive review of the literature confirmed its superior accuracy to the conventional method regarding the positioning of the glenoid component. 14 The navigation has benefits for both ATSA 1,10,16 and RTSA, 12,15,16,21 especially when the anatomy is distorted by fractures, revisions, wear, or dysplasia of the glenoid. 9,10 The contraindications to navigation are the same for shoulder arthroplasties, such as active or latent infection and generally poor health.…”

ResumoA indicação de artroplastias do ombro aumentou progressivamente. O posicionamento preciso dos componentes pode ter implicações significativas para os resultados clínicos. A navegação utilizada para auxiliar no desempenho de artroplastias totais anatômicas e reversas tem proporcionado maior precisão na colocação do implante, especialmente do componente glenoidal. O desenvolvimento da técnica, do material e do desenho da prótese têm mostrado resultados encorajadores e levado a uma tendência de expansão da sua utilização. Dessa forma, estimamos uma maior sobrevida das artroplastias resultantes de menores taxas de instabilidade e soltura precoce. Nosso objetivo é descrever a técnica atual e apresentar os resultados da literatura com navegação. No entanto, estudos clínicos comparativos com acompanhamento de longo prazo são necessários para comprovar a eficácia nos resultados finais das artroplastias totais do ombro.

“…In order to improve glenoid implant positioning, recent techologies have emerged and are now in widespread use, such as CT scan-based planning, multiplanar & 3D planning, patient speci c instrumentation (PSI), along with computer-assisted and navigated procedures. [6,[15][16][17][18][19] These new techniques have shown encouraging results [6,8,15,17,20]. However, many present a common signi cant limitation: the high variability of the bony landmarks (i.e.…”

Purpose Glenoid component positioning is an important determinant of outcome in anatomic shoulder arthroplasty. This is dependent on the accurate preparation of bony surfaces. We describe and assess a novel plane for improving the accuracy of bony preparation - the Glenoid Vault Outer Cortex plane (GvOC). Research question Does the GvOC plane provide a more accurate representation of glenoid version and inclination than the standard scapular border (SB) method ? Methods 105 CT scans of normal scapulae were obtained. 46 females and 59 males, aged between 22 to 30 years. Accuracy of the GvOC was compared against the current ‘gold standard’ – the SB method. Measurements of glenoid inclination, version, rotation, and offset were made using both GvOC and SB planes. These were compared to 'actual values' obtained using an alternative method. Results The mean difference between estimates of version based on the GvOC plane and the reference value were 1.8° (-2 to 5, SD 1.6) as compared to 6.7° (-2 to 17, SD 4.3) when the SB plane was used, (p<0.001). The mean difference between estimates of inclination based on the GvOC plane and the reference value were 1.9° (-4 to 6, SD 1.6) as compared to 11.2° (-4 to 25, SD 6.1) when the SB plane was used, (p<0.001). Conclusions The GvOC plane produced estimates of genoid version and inclination closer to the actual with a lower variance than using the standard SB plane. This may provide a more accurate and reproducible method for surgeons when defining native glenoid anatomy.

“…[1][2][3][4][5] Kelly et al 6) proposed the '12 mm rule', stating that when inserting the glenoid component, screw placement in the location 12 mm above the inferior glenoid rim led to good results. Theopold et al 7) reported that the accuracy of glenoid component insertion can be improved by navigation based on three-dimensional (3D) images after insertion of the guide wire into the glenoid in the operation. In this way, many studies of fixation of glenoid implants have been conducted because it is known that there is a high incidence of glenoid bone loss and the glenoid fixation position has an important result on the glenoid component.…”

“…If fixation of the glenoid component is not properly fixation, it gives rise to problems such as failure of initial fixation of the glenoid component, instability, and scapula notching. 1,[7][8][9][10] This is due to the fact that the exposure of the glenoid cavity is a rather difficult technique and the scapula has a complex anatomical shape. 1,7,11) In order to improve the accuracy of glenoid component insertion in shoulder arthroplasty, techniques, such as navigation and patient-specific guide or instrumentation have been introduced.…”

BACKGROUND: We analyzed the angle between the glenoid anterior surface and glenoid axis, the range of the glenoid apex and the location of the glenoid apex for assistance during shoulder surgery.METHODS: Sixty-two patients underwent a computed tomography of the shoulder with a proximal humerus fracture. In the range of the glenoid apex, the ratios of the distribution of triangles with a Constant anterior and posterior area of the glenoid were measured. The location of glenoid apex was confirmed as the percentage of the position with respect to the upper part of the glenoid with the center of the part, analyzed the angle between the glenoid anterior surface and glenoid axis was measured.RESULTS: The angle between the glenoid anterior surface and glenoid axis was 19.80° ± 3.88°. The location of the glenoid apex is 60.36% ± 9.31%, with the upper end of the glenoid as the reference. The range of the glenoid apex was 21.16% ± 4.98%. When the height of the glenoid becomes smaller, the range of the glenoid apex tends to become larger (p=0.001) and the range of the glenoid apex becomes wider (p=0.001) as the glenoid width narrows.CONCLUSIONS: We believe the anatomical measurements of the glenoid will be helpful for a more accurate insertion in glenoid component. It is thought that more accurate insertion is possible if we can set other anatomical measurements using computed tomography imaging of the glenoid which can develop into the study of other anatomical measurements.
