ObjectiveCongenital hip dysplasia is a common orthopedic disorder in childhood. MRI is widely used to image high grade dysplastic hips after reduction and fixation within a cast. The purpose of this study was to optimize and shorten the MR study to the requests of the pediatric orthopedic surgeons. Material and Methods13 consecutive MR studies of the hip were included in the study (1-5 months of age) between 2003 and 2011. Two pediatric orthopedic surgeons, who were blind for the diagnosis and therapy of the study patients, evaluated all magnetic resonance images (MRI) to determine the type of hip dysplasia. The usefulness of the MR-images was assessed using a 5-point scale. The type of hip dysplasia was assessed using the Tönnis criteria. In addition two radiologists in consensus evaluated the status of sedation and motion artifacts. Original MRI-reports were reviewed. ResultsThe most valuable sequences for the position of the femoral head and the evaluation of the anatomic details of the 13 MR-studies were: (a) In coronal planes: TIRM 3 mm (Score 4.6), T2 TSE 3mm (Score 4.1). (b) In axial planes: PD axial 3mm (Score 4.75), DESS reformats 1.5 mm (Score 4.5). (c) All sagittal sequences and non-fat saturated T1w images were not supportive for the orthopedic surgeons. Mild and major motion artifacts are observed in 33% of the patients with sedation and in 71% without sedation. ConclusionAfter reduction of high-grade hip dysplasia and Spica-cast fixation, MRI examination offers valuable information for the orthopedic surgeon. The MRI study may fulfill the orthopedic surgeon's needs using only one coronal and axial plane (e.g. T2w, PD or DESS) to image the dysplastic hip after treatment in a Spica-cast reliably. The shortening of the protocol may reduce the requirement of general anesthesia or sedation, however optimal images without motion artifacts play an important role in image interpretation.

SUMMARYObjective: In this study, the effectiveness of magnetic resonance imaging (MRI) in patients with developmental dysplasia of the hip (DDH) after reduction was examined. Method: Forty-two hips of 31 patients treated between 2003 and 2012 were examined prospectively. The femur head and acetabulum interaction were examined by MRI performed postreduction. Results: The average follow-up period was 40.47 ± 36.52 months. Eleven, 10 and 10 patients were diagnosed as bilateral (B), right (R) sided and left (L) sided, respectively. The average age on MRI was 13.1 months (min, 5; max, 24). MRI was obtained without sedation, except in three patients. The mean MRI duration was 5.21 min (range, 3.55-10.50 min). Concentric reduction was monitored in 19 hips of 15 patients. Postreduction redislocation was monitored in eight hips of six patients. Conclusions: MRI was beneficial in DDH because it was able to assess the hip extensively, did not require anesthesia, and did not use radiation. MRI provided advanced structural information that enabled the assessment of potential prevention of reduction. MRI was found to be an effective treatment scheduling method for DDH at an early period postreduction. MRI should be used more commonly in DDH.

Emekleme çağına gelen altı aylıktan büyük çocuklarda Pavlik bandajı kullanımı çocuğun hareketlenmesine bağlı olarak etkinliğini kaybetmeye başlar. Altı aylıktan büyük çocuklarda Pavlik bandajı tedavisinin başarı oranı %50'den azdır. [1] Bu yüzden sublukse veya disloke kalçalarda sıklıkla kapalı veya gerekli olgularda açık redüksiyon uygulanır.Bir yaş altındaki GKD grubunda geçmişe göre daha az tercih edilse de, en çok tercih edilen tedavi traksiyon uygulanarak veya uygulanmadan yapılan kapalı redüksiyondur. Eğer kapalı redüksiyon başarılı olursa hasta üç ay süre ile pelvi pedal alçı ile immobilize edilir. Eğer kapalı redüksiyon başarılı olmaz ise açık redüksiyon gerçekleştirilir. Açık redüksiyon gereken 12 aylıktan
