[Results and experiences of conversion of hip arthrodesis ].
With the predictably good outcome of total hip arthroplasty today (THA), hip arthrodesis currently has limited indications. Over the long term, however, most patients develop secondary degenerative arthritis in the spine, contralateral hip, and ipsilateral knee due to overloading. The deteriorating condition of these joints eventually causes the onset of pain, which often requires conversion of a fused hip to a THA. The results and experiences of conversions of a hip arthrodesis into a THA are reported. ⋯ We conclude that this operation can lead to satisfactory results even after a long duration of the arthrodesis. There is a high rate of complications after conversion of a hip arthrodesis to a total hip arthroplasty. These issues must be carefully considered and discussed with the patient before any conversion procedure.
