Abstract Background Developmental dysplasia of the hip (DDH) can lead to pain and premature secondary osteoarthritis at an early stage. Joint-preserving osteotomy is an established solution to this problem. In contrast, a conservative approach would result in pain persistence, ultimately raising the patients question for a possible date of expected prosthesis implantation. The aim of the study was to identify the relationship between the dysplastic hip anatomy and the time of prosthesis implantation in order to enable prognostic predictions in younger patients with symptomatic DDH. Materials and methods Data from 129 hips who received THA due to secondary DDH osteoarthritis were evaluated. The preoperative hip anatomy was evaluated for AI and LCE angle. Multiple linear regression analyses were then used to correlate the influence of these parameters with the patient’s age at the time of surgery. In addition, a graphical relationship was derived by the method of power least squares curve fitting with second-degree polynomials. Results The mean age for THA was 54.3 ± 11 years. The time of surgery correlated significantly with LCE (0.37) and AI (− 0.3) (p < 0.001). The mean age of patients with LCE angle ≤ 10° was 41.9 ± 14.0 years, for LCE 11–20° 52.7 ± 9.5 years, and for LCE 21–30° 57.0 ± 10.3 years. The following formula could then be determined for the calculation of the potential patient age at the time of THA as a function of LCE angle: age pTHA = 40.2 + 0.8 × LCE angle − 0.01 × (LCE angle)2. Conclusion A significant correlation between the extent of dysplasia and the time of prosthesis implantation was identified. In particular, the LCE and the AI correlated strongly with the time of implantation. The more dysplastic the angles were, the sooner the THA was necessary. Using the calculations presented in this study, the probable age of prosthesis implantation can be prognosticated and included in a counseling session about treatment options for DDH.

Aim To assess the relationship between the clinical sign of excessive hip abduction (abduction of the hip 90 degrees or more) and developmental dysplasia of the hip (DDH). Methods The research was conducted on 450 newborns in the Neonatal Unit at the Clinic of Gynecology and Obstetrics and the Clinic of Orthopedics and Traumatology of the University Clinical Centre, Tuzla, between 30th August 2011 and 30th April 2012. Clinical (degree of hip abduction) and ultrasound examination of all newborns hip were performed using the Graf method on their first day of life. Results Clinical sign of excessive hip abduction showed significant predictive value for DDH. There were 37 (8.2%) newborns with the clinical sign of excessive hip abduction, of which 13 of them had DDH while 24 of them did not have this clinical sign. There were 89 newborns, in the overall sample, with one of the forms of DDH, 13 (12.7%) of them had this clinical sign, while from 324 newborns witouth DDH, 24 (6.9%) had this clinical sign. Excessive hip abduction had a positive predictive value (PPV) of 35.1% and a negative predictive value (NPV) of 78.5% for DDH. Conclusion Excessive hip abduction is an useful and important clinical sign of DDH. Doctors who perform the first examination of the child after birth, would have to turn their attention to this clinical sign. The newborns with this clinical sign would have to go to an ultrasound examination of the hips for further diagnosis.

Dysplasia Of The Hip

Distal trochanteric transfer (DTT) has been widely performed to treat developmental dysplasia of the hip or Perthes disease. Total hip arthroplasty (THA) following DTT in patients with hip osteoarthritis is one of the most challenging procedures for hip surgeons, because great care must be taken regarding anatomical abnormalities of the greater trochanter and the soft tissue attached to the greater trochanter. To the best of our knowledge, there are no reports on THA after DTT. We herein report two cases of patients who underwent THA post DTT using cementless components. After THA, both patients developed abduction temporary contraction because of leg length extension and gluteus medius hypertension. However, in both cases, the contraction was reversible within two months and the final clinical result was good. Therefore, THA can be considered an effective and safe choice for treating osteoarthritis after DTT.
