Results of medial open reduction of developmental dysplasia of the hip with regard to walking age.

This study aimed to evaluate the outcome of medial open reduction for developmental dysplasia of the hip (DDH) in patients before and after walking age. A minimum 5-year radiographic and clinical follow-up compared 29 patients (group 1) before walking age with 38 patients (group 2) after walking age for DDH. The correction ratio of acetabular index was similar in both groups postoperatively (41.8% for group 1 and 44.9% for group 2), and it was statistically not significant (P>0.05). The Kalamchi-MacEwen classification showed no correlation between operative age and the rate of avascular necrosis (P>0.05). This report presents similar complication rates as that of the Severin criteria for medial open reduction of the hip and challenges the conventional belief that a medial open reduction for the treatment of DDH in a walking-age child at short-term to mid-term follow-up has comparable results.

Prevalence of developmental dysplasia of the hip in preterm infants with maternal risk factors.

PURPOSE: The aim of this study was to determine the prevalence of developmental dysplasia of the hip (DDH) in preterm infants with maternal risk factors. METHODS: A prospective review of the medical records and ultrasound (US) scans of all preterm infants at one tertiary-care children's hospital was completed to identify all premature infants without any infantile risk factors at a particular time frame. We consecutively evaluated 421 babies (842 hips) who satisfied the criteria for inclusion. Hip US images were classified according to Graf. RESULTS: Overall, one hip was diagnosed as DDH (Graf type 2c). Female infants had significantly lower alpha angles (70.2 ± 6.6 and 71.4 ± 4.4 for females and males, respectively) (P = 0.033). There was no correlation between oligohydramnios and alpha and beta angles and hip sides (P = 0.345 and P = 0.789 for left and right hips, respectively). US examination of the infants revealed no differences between the alpha and beta angles of the hips and birth weight and age at gestation. Although it was statistically not significant, US evaluation of left hips among singletons demonstrated one immature hip (P = 0.864) and that of right hips demonstrated one immature hip for both singletons and twins (P = 0.904). CONCLUSIONS: Prematurity with or without maternal risk factors does not have an effect on DDH.

Minimally invasive treatment of simple bone cysts with percutaneous autogenous bone marrow injection.

Percutaneous autogeneic bone marrow injection is an effective method for managing simple bone cysts, and it might be considered before the application of more extensive procedures.

[Anterior dural laseration due to thoracolumbar burst fracture]. / Torakolomber burst kirigina bagli anterior dural laserasyon.

BACKGROUND: This study investigated the incidence, prediction, and treatment principles of anterior dural laseration due to thoracolumbar burst fracture. METHODS: Three anterior dural tears were found during anterior decompressive spine surgery. The average age was 42. Preoperative neurologic status and radiologic data of the patients were analyzed retrospectively. The average follow-up was 20 months. RESULTS: Anterior dural tears detected in 3 (8.2%) of 35 burst fractures. Primary repair were performed in two patients. There were no cerebro-spinal fluid leakage perioperatively and all patients were neurologically intact at the final follow-up. CONCLUSION: It is too difficult to detect anterior dural tear before surgery. Anterior dural tear should be suspected in patient with neurologic deficit and asimetric bony retropulsion into the spinal canal.
