Just before the holiday, Motley Crue frontman Vince Neil underwent hand surgery in Nashville. The musician posted about it via his Instagram account, revealing a condition he had in the process.

"Hand surgery today," Neil wrote on Wednesday, then offering the hashtags #VikingDisease #Dupuytrenscontracture and #Nashville.

The first two hashtags reveal what he was being treated for, as Dupuytren's Contracture, often known as "Viking's Disease," prevents curled fingers from being able to straighten. The nickname comes from the condition being disproportionately found in people of Northern European descent.

In other Motley Crue news, the band is celebrating the 30th anniversary of the Dr. Feelgood album with a new deluxe 30th anniversary edition. Certified six times platinum in the U.S., the album is the band's biggest selling release. It topped the charts and also earned the band Grammy nominations for the title track as well as "Kickstart My Heart," and won the Best Hard Rock/Heavy Metal album at the American Music Awards in 1991.

Nikki Sixx said of the disc, "After feeling robbed of a No. 1 album with Girls Girls Girls, the band was hell bent on topping ourselves on every level. Bringing in Bob Rock to produce and push us musically and lyrically was just what the doctor ordered… The band was clean, lean and sober and this album has some of our proudest work."

The deluxe edition will include colored vinyl, three 7" picture discs, a doctor bag, deck of cards, prescription notepad, drumstick pens, pins, guitar picks, band aids and more. In addition, the band is launching an anniversary line of Dr. Feelgood apparel that includes the album artwork.
