Minor is a relative term.<br/><br/>For example: A broken limb is a minor thing to fix in terms of 24th century medicine, but if not fixed would disqualify the officer from standing his watch. I believe that under the ST:NG medical rules-of-playit takes a couple of hours to fix a broken bone, but I will check...<br/><br/>Hmmm... Okay, so the correct device is an osteo-regenerator, but there is no indication of how long one takes to work. I expect it would depend upon the severity of the fracture...<br/><br/>
