Does non-operative reduction using horizontal traction prevent the need for secondary surgery in patients with developmental dysplasia of the hip treated after nine months of age?
Does non-operative reduction using horizontal traction prevent the need for secondary surgery in patients with developmental dysplasia of the hip treated after nine months of age?
Non-operative reduction using horizontal traction for developmental dysplasia of the hip after nine months of age resulted in 12 of 31 hips requiring secondary extra-articular surgery over a mean 11.7-year follow-up.

Traction reduction may not avert secondary surgery in late DDH; leaves open its role pending controlled studies.
Over a 20-year period we treated 29 patients (31 dislocated hips) by non-operative reduction after nine months of age, using horizontal traction. They were followed up for a mean of 11.7 years, and 12 hips required secondary extra-articular surgery. The clinical result was excellent in 25 hips, good in four and fair in two. Of the 29 hips for which detailed radiographs were available, 18 achieved Severin grade I, nine grade II and two grade III. There were no major complications and, in particular, no cases of avascular necrosis. The non-operative reduction of late-presenting developmental dysplasia of the hip is still a viable option. It has a potential for excellent results and a very low complication rate.
