Do ion levels in metal-on-metal hip resurfacing differ from those in metal-on-metal THA at long-term followup?

abstract：:There are 2 fairly common types of spondylolisthesis in children - dysplastic and isthmic. The dysplastic type is secondary to congenital defects at the lumbosacral joint. The isthmic is usually due to a fatigue fracture of the pars interarticularis but there is also an hereditary element in this type. Most children w...
