 Diagnostics included a magnetic resonance (MR) angiography, an X-ray of the forearm, repeated nerve conduction velocity assessments, and sonography of the nerves ( Fig. 1b, c ) and muscles of the forearm. Subsequently, the typical Volkmann contracture developed and could be observed 18 weeks postinjury ( Fig. 1a ). 
Steps of the surgical procedure after neurolysis and stepwise tenolysis and tenotomies.

We excised severely fibrotic and thickened fascia tangentially via a proximal incision the size of the distal incision ( Fig. 2 ) in an attempt to improve muscle function, as it has proven to be successful on the lower extremity. Here, the median and ulnar nerves ( Fig. 2a ) alongside the radial and ulnar arteries were microsurgically depicted and spared. Fig. 2b ). Finally, an elongation of the M. flexor pollicis longus tendon allowed for full extension of all fingers and wrist.
