Sir,
I read with interest the recent technical innovation article entitled “Spica MRI after closed reduction for developmental dysplasia of the hip” [1]. The authors report the use of a short MRI examination immediately following placement of a spica cast to confirm proper reduction. Although not included in the reference list of this recent publication, many points discussed regarding this technique have been described previously [2, 3]. After publication in 2000, postoperative limited spica MRI evaluation completely supplanted the use of CT at our institution. The lack of radiation exposure or need for sedation, improved soft tissue delineation, rapid imaging time, ease of scheduling and reduced comprehensive cost supported prompt acceptance of the practice by our orthopedic surgeons. Hopefully, this current publication reiterating the previously reported findings will further promote the widespread use of this practice.
