Wolff's law
Wolff's Law is defined "Bone in a healthy animal will adapt to the loads under which it is placed." Many famous studies have observed bone hypertrophy as a result of functional loading:
pubmed.ncbi.nlm.nih.gov
link.springer.com
www.sciencedirect.com
It makes sense; you're only as strong as your skeleton, so bones have the potential to grow stronger just like muscles do. Mechanical loading applies tension through tendon and ligament attachments, resulting significantly more in increases of density rather than mass. However, bones can also be loaded directly, also consistently resulting in hypertrophy outcomes:
pubmed.ncbi.nlm.nih.gov
reader.z-library.sk
In these studies, we see measurable increases in bone mass as a result of repeated direct bone loading. Much more than density, measurable and significant increases in actual bone mass.
Actual rates of bone growth:
Finally, I'll address a claim that seems to be brought up in any conversation of bonesmashing. There's this idea that the "growth" people are seeing can't be actual bone because "real" bone hypertrophy adaptation is too slow to notice. I've heard claims that the maximum amount of bone growth adaptation is 0.2-0.5mm a year, or even much less. While these low numbers are consistent with some of the research on bone adaptation to more static, functional loading, they do not apply to bonesmashing techniques. Bonesmashing is not only direct bone loading, it is a dynamic and high impact stress completely incomparable to traditional studies of Wolff's Law. If there are any applicable studies demonstrating some kind of growth rate cap for a comparable activity, I haven't seen it.
The potential growth rate of adult bone is an excess of 30mm per month, as seen in distraction osteogenesis operations such as leg lengthening surgery. This is done in a clinical environment using entirely different methods than bonesmashing, but says quite a bit for the actual hypertrophy potential bones are capable of.
Tldr;
Wolff's law is legit, bonesmashing grows actual bone.
This is just a brief overview, I'm planning a much bigger post about bonesmashing in the future. Please post any anti-bonesmashing arguments or questions you have and they might make it into my next post.

The phenomenon of twisted growth: humeral torsion in dominant arms of high performance tennis players - PubMed
This manuscript is driven by the need to understand the fundamental mechanisms that cause twisted bone growth and shoulder pain in high performance tennis players. Our ultimate goal is to predict bone mass density in the humerus through computational analysis. The underlying study spans a unique...

Total and regional bone mass in female soccer players - Calcified Tissue International
This cross-sectional study investigated bone mass in female athletes participating in an impact-loading sport (soccer), and evaluated whether any changes in bone mass could be related to the type of weight-bearing loading and muscle strength. The group of soccer players consisted of 16...

Mechanical influences in bone remodeling. Experimental research on Wolff's law
Three (3) complementary in vivo experiments using dog ulnas demonstrated that adaptive hypertrophy of long bones is provoked only by intermittent comp…

Periosteal thickening as a manifestation of trauma in infancy - PubMed
This paper reports the findings in a study of the incidence of periosteal elevation in children and its possible relationship to child abuse. Two separate sets of radiographs of the skeleton of children were taken for a variety of diagnostic purposes. The suspected abuse set consisted of 59...
