Pediatric hip diseases account for 9% of all primary hip
arthroplasties in the Norwegian Arthroplasty Register. We wanted to validate the
diagnosis as reported to the register and to assess the quality of life of these
patients after hip replacement. METHODS: 540 patients accepted to
participate in this follow-up study (634 hips).
All were less than 40 years of
age and had been reported to the Norwegian Arthroplasty Register as having
undergone a primary total hip arthroplasty (THA) between 1987 and 2007. The
underlying diagnosis, age at diagnosis, and type of treatment given prior to the
hip replacement were recorded from the original hospital notes. RESULTS: The
diagnoses reported to the Norwegian Arthroplasty Register were confirmed to be
correct in 91% of all cases (538/592). For the 94 hips that had been treated due
to Perthes' disease or slipped capital femoral epiphysis (SCFE), the diagnosis
was verified in 95% of cases (89/94). The corresponding proportion for
inflammatory hip disease was 98% (137/140) and it was only 61% for primary
osteoarthritis (19/31). The self reported quality of life (EQ-5D) was poorer for
these young patients with THA than for persons in age-matched cohorts from Great
Britain and Sweden, except for those with an underlying SCFE. INTERPRETATION: The
diagnoses reported to the Norwegian Arthroplasty Register as the underlying cause
of THA were correct in 91% of cases. Individuals who undergo THA before the age
of 40 have a reduced quality of life, except for those requiring a hip
replacement because of SCFE.
