How did the accidents Henri de Toulouse-Lautrec suffered in 1878 and 1879 affect his legs?

In 1878, Henri de Toulouse-Lautrec suffered an accident in which he broke his left thighbone, followed by a second mishap a little more than a year later that fractured his right thighbone. These accidents required extensive periods of convalescence and often painful treatments, which ultimately left his legs atrophied and made walking most difficult.1

During these long, often lonely periods of recovery, he devoted himself increasingly to art to pass the time. While some have interpreted his frequent artistic choice to obscure or omit the legs of his subjects as a reaction to his own condition, this technique was actually a deliberate stylistic device used to eliminate specific movement and replace it with the essence of movement.12
