Both your examples actually show that strontium works; the first in its facts; the second in its conclusion

Firstly, the shmababstract actually shows a patient at the initial visit before strontium with poor bone health, diffuse demineralization of her sternum, and a fracture.
Then she begins strontium,
"3 years later, bone densitometry showed osteopenia of the lumbar spine (T-score -1.6), normal hip (T-score -0.4) and normal femoral neck (T-score -0.7). This demonstrated a remarkable increase of 20% in hip bone density and 31.7% in lumbar spine bone density in only three years." No more fractures in those 3 years.
The researchers don't believe it so they title the report of what they don't believe as strontium not all its cracked up to be.....no bad dexa, no fractures, just a good dexa that they can't disprove.
Plus, I cannot locate the study which they mention and neither can ai mode. and the studies which they quote are not cited or linked in this article.
And plus, plus, the fact that she stopped fracturing would make any endocrinologist skip for joy.
In addition this article is from a hospitalist conference, not a bone‑metabolism research group. These abstracts often:
• highlight “surprising” or “gotcha” cases
• use dramatic titles to attract attention
• misunderstand the known DXA‑strontium interaction
• assume that any DXA increase from strontium is “fake”
But the DXA increase is not fake — it reflects real mineral incorporation.
The only question is how much of the increase is due to strontium vs. new bone formation.
Even conservative estimates still show real gains.

To beat a "dead horse" again REMS and TBS make the dexa skew of strontium moot now. In other words, TBS and REMS are not affected as the DEXA by the denser strontium and they show good bone density and bone quality for strontium users.

The next quoted section in your post is not from the hotlink which you provided and is not the conclusion which the actual research with that quote reached.

Here is part of the actual conclusion and the actual hot link for the research which says strontium showed great results similar to other osteoporosis drugs:
"The results of the SOTI and TROPOS studies confirm that strontium ranelate is a safe and effective treatment to prevent vertebral fractures and hip fractures in women with postmenopausal osteoporosis. The 40% reduction in vertebral fracture risk found in the pooled analysis (Roux et al 2006) is similar to that found in trials of other osteoporosis treatments including alendronate (Black et al 1996), risedronate (Harris et al 1999), ibandronate (Chesnut et al 2004), and raloxifene (Ettinger et al 1999). Strontium ranelate has also been proven to reduce non-vertebral fracture risk by 15% (Roux et al 2006). This includes the prevention of hip fractures in older patients with a femoral neck BMD T-score"
