Coxa Magna (CM) is defined as a condition in which the horizontal (transverse) diameter of the femoral head is larger on the affected side than on the intact side. CM can occur as a manifestation of avascular necrosis (AVN) following treatment for the developmental dysplasia of the hip (DDH). Alternatively, it can also be secondary to other hip disorders, such as Perthes’ disease. This study aimed to determine the prevalence and indicators of CM and AVN of the femoral head that can be detected during follow-up in patients with unilateral DDH treated with closed reduction (CR) or open reduction (OR) surgery. The files of 143 patients treated for unilateral DDH between January 1997 and December 2017 were reviewed retrospectively. A total of 104 patients, including Group 1 (n = 49) patients who underwent CR under general anesthesia and Group 2 (n = 55) patients who underwent OR were included in the study. CM; It was considered as the case where the femoral head was 15% or more larger than the intact side. A total of 104 patients were followed up for 77.27 ± 13.96 months, with a mean age of 15.43 ± 7.76 months. When Group 1 and Group 2 were compared, there was no statistical difference in terms of sex, side, adductor tenotomy, and AVN (P > 0.05). CM developed in 22.4% (n = 11) of the patients in Group 1 and in 49.1% (n = 27) in Group 2, and the difference was statistically significant (P = 0.008). When the effect of independent variables on the development of CM is evaluated with the multivariate logistic regression model, the risk of developing CM is 3474 times higher in those who underwent iliopsoas tenotomy compared with those who did not. The primary outcome of this study is that CM is more frequent in patients treated with OR for DDH. CM may be a nonpathological condition that occurs in connection with iliopsoas tenotomy or surgical treatment. Prospective studies with a larger number of cases, designed to minimize confounding factors, are required.

“…In this study, the authors reported quite wide range in terms of reliability; 3.6%-44.5% agreement range in alpha angle measurement and 0.9%-45.3% agreement range in beta angle measurement were reported (23). Likewise, it has also been reported that the variations of positioning the infant and the XR device may cause diversity especially among the distinct experience levels of physicians evaluating the x-rays (26). Ismiarto et al analyzed the interobserver reliability between junior and senior orthopedic residents for XR using Fleiss kappa test.…”

We aimed to compare the interobserver reliability of ultrasonography (USG) and x-ray (XR) and to calculate the sensitivity and specificity of these tests in the diagnosis of developmental dysplasia of the hip (DDH). This retrospective study was conducted among 150 USG and 300 XR images of infants examined for DDH between January 2013 and June 2015. The sonographic angle measurements and hip classifications of each USG and XR were carried out by five orthopedic surgeons specialized in pediatric orthopedics. Both USG and XR showed almost perfect agreement between five observers (κUSG=0.936, κXR=0.927, respectively, p<.0001). In patients under the age of 6 months, the interobserver reliability was almost perfect for USG and substantial for XR (κUSG=0.957, κXR=0.809, respectively, p<.0001). In patients older than 6 months, although interobserver agreement of both tests were almost perfect (κ>0.81), XR showed slightly higher agreement than USG (κXR=0.912, κUSG=0.885, respectively, p<.0001). In the diagnosis of DDH, both USG and plain x-rays are effective radiological tests because they offer high interobserver reliability. However, the surgeon's practical training and experience significantly affect the reliability in the evaluation of pediatric hip USG and XR.

Įgimta klubų sąnarių displazija yra viena iš dažniausių naujagimių atramos ir judėjimo sistemos problemų. Klubo sąnario displazija − tai klubo sąnarį sudarančių kaulų ir kremzlinių struktūrų (gūžduobės ir šlaunikaulio galvos) anatominių nuokrypių nuo normos visuma. Klubo sąnario displazija gali susiformuoti vystantis vaisiui gimdoje ar kūdikystės laikotarpiu. Ankstyva šios patologijos diagnostika ir pradėtas gydymas naujagimystėje ir kūdikystėje gali gerokai sumažinti neįgalumą bei pagerinti gyvenimo kokybę vyresniame amžiuje. Klubo sąnario displazijos nustatymas naujagimiams rentgenologiniu tyrimu nėra informatyvus ir patikimas diagnostikos metodas. Klubo sąnarių tyrimas ultragarsu leidžia jau pirmomis gyvenimo dienomis nustatyti naujagimio klubo sąnario kaulinių ir kremzlinių struktūrų išsidėstymą. Diagnozuoti ir stebėti šios patologijos eigą naudojama klubų sąnario displazijos Graf klasifikacija. Ji pagrįsta alfa kampo, esančio tarp gūžduobės kaulinio stogo, matavimu ultragarsinio tyrimo metu. Tai neinvazyvus tyrimo metodas, todėl jį galima atlikti keletą kartų, nesukeliant jokių šalutinių padarinių. Šio darbo tikslas − įvertinti, susisteminti ir išanalizuoti mokslinėje literatūroje pateikiamus duomenis apie įgimtą Graf IIa tipo klubų sąnarių displaziją ir kokią taktiką geriausia pasirinkti gydymui.
