ABSTRACT

Exposure to the pressure experienced by higher birth weight babies during the intrauterine period might cause hip dysplasia. The aim of this study is to determine the effect of birth weight in newborns on hip ultrasonography when the paternal and maternal risk factors are excluded. A total of 701 babies born at 38-42 gestational weeks were included in the study. Hip ultrasonography was performed within 7 days following birth using the Graf technique in the babies without risk factors for developmental dysplasia of the hip. Images obtained were controlled with respect to conformity to the Graf method and angular measurements were performed. According to the α and ß angle values obtained, type 1A and 1B hips were categorized as mature; type 2A hips were categorized as immature; and type 2C, D, 3A, 3B, and 4 hips were categorized as pathological hips. The results obtained were analyzed for the effect of birth weight on the angular values and hip typing. The birth weight of the babies was 338,488 ± 48,241 g (2030-6124 g). It was determined that the birth weight had no effect on the values of α and ß angles in the male babies (P=0.21, 0.76). It was determined that increasing birth weight decreased the α angle value (P=0.001) and caused no difference in the ß angle value (P=0.057) in the female babies. It was found that birth weight had no effect on hip typing in both female and male babies (P=0.060, 0.22). Increases in birth weights caused decreases in ultrasonographic α angles only in female babies.

ABSTRACT

In order to assess interobserver and intraobserver reliability of an evaluation system of the International Clubfoot Study Group, 30 children treated for unilateral clubfoot and their radiographs were examined by three different observers. The mean intraobserver kappa value was found to be 0.62. The mean interobserver kappa value was 0.73. These kappa values correlated with a substantial degree of agreement. Interobserver reliability for all subgroup evaluations (morphologic, functional and radiological) and total scores was 90% or over. This also indicates a good interobserver reliability. In conclusion, the Bensahel et al. and International Clubfoot Study Group outcome evaluation system may be used reliably for the assessment of outcome of the treatment of clubfoot.

ABSTRACT

We aimed to determine if there are mechanoreceptors in the hip joint capsule and ligamentum capitis femoris (LCF) of patients with developmental dysplasia of the hip (DDH). We took capsule and LCF biopsies from 20 hips of 20 patients who were operated on because of DDH. The mean age was 10.2 months (range 6-20 months) at the time of surgery. There were 12 girls and eight boys. Teratologic and secondary hip dislocations were not included in this study. Full thickness, 0.5 x 0.5 cm anterior capsule and LCF portions were taken for biopsy specimen. Specimens were stained with hemotoxylin eosin and examined immunohistochemically using monoclonal antibody against S-100 protein. In both analyses no mechanoreceptor was found in any samples of capsule or LCF. In this preliminary study we could not find mechanoreceptors in the local anterior joint capsule and LCF of the hip in children with DDH. We think that additional studies are necessary in order to understand the mechanoreceptor characteristics of the hip joint in children not only with DDH but also in children with healthy hips.

ABSTRACT

OBJECTIVES: We evaluated the results of femoral shortening by subtrochanteric segmental resection in patients who underwent total hip replacement (THR) for high total dislocation of the hip. METHODS: We performed THR in 19 hips of 16 patients (15 females, 1 male; mean age 41 years; range 22 to 55 years) with high total dislocation of the hip. All the patients had severe hip pain. In all cases, femoral shortening by subtrochanteric segmental resection and an anatomical reconstruction of the acetabulum were performed with the use of cementless femoral components and cementless acetabular components with screws, respectively. The Harris hip scoring system was used for functional assessments. Radiologic assessments were based on the DeLee and Charnley criteria for the acetabular component, and on the Gruen zones and the Engh criteria for the femoral component. The mean follow-up period was 44 months (range 22 to 79 months). RESULTS: Union was achieved in all cases in a mean of 14 weeks (range 11 to 15 weeks). The mean leg length discrepancy decreased from 4 cm to 1.5 cm postoperatively. A positive Trendelenburg sign was found in 13 patients and four patients before and after surgery, respectively. The mean Harris hip score improved from 37 to 83 postoperatively. None of the patients developed deep infection, dislocation, sciatic nerve palsy, or nonunion at the osteotomy site. No clinical and radiologic signs of loosening were observed and no revisions were required. CONCLUSION: Femoral shortening with subtrochanteric segmental resection in THR is a safe technique in patients with high total dislocation of the hip, leading to satisfactory functional results.

ABSTRACT

Asymmetric bilateral (one side anteriorly, the other posteriorly dislocated) traumatic hip dislocations are very rare. We present a 21-year-old male patient who had simultaneous anterior and posterior traumatic hip dislocations due to a car crash. He also suffered from a tarsometatarsal (Lisfranc's) fracture-dislocation. The patient underwent conservative treatment and was followed-up for 44 months. Final evaluations with Thompson and Epstein radiologic and clinical criteria showed an excellent result. To our knowledge, this is the first report of a case with asymmetric bilateral traumatic hip dislocations associated with Lisfranc's injury.
