PURPOSE To report complications of direct fibrosing agent injection in the treatment of aneurysmal bone cysts (ABCs) in children. MATERIALS AND METHODS The authors retrospectively analyzed all cases of ABCs treated with direct fibrosing agent injection (Ethibloc; Ethnor Laboratories, Ethicon, Noderstedt, Germany) at Robert Debré Hospital since 1994.(More)
Forty-seven children with fractures of the lateral condyle were reviewed, 4 of whom were treated after a five month delay. The roentgenographic study revealed 4 different types of fractures according to the degree of displacement. Each type corresponded to precise anatomical lesions. In the treatment of recent fractures, we must distinguish between strictly(More)
Inoculation of blood culture vials with joint fluid samples has revealed the important pathogenic role of Kingella kingae in pediatric arthritis. However, recent studies based on broad-range 16S ribosomal DNA PCR and real-time PCR without a probe suggest that conventional methods remain suboptimal. We developed a new real-time PCR method with a probe that(More)
BACKGROUND The selection of fusion levels continues to be controversial in adolescent idiopathic scoliosis (AIS). The classifications of King and Lenke remain the most widely used, but recent studies have demonstrated their shortcomings, including poor interobserver reproducibility. We propose a method of preoperative planning that is independent of(More)
STUDY DESIGN Retrospective study of prospectively collected data. OBJECTIVE Compare Universal Clamps (UCs) and hooks for the thoracic correction of adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA In scoliosis surgery, sagittal correction is as important as frontal correction due to the risk of junctional kyphosis. Compared to all-screw(More)
We report the results of 116 consecutive displaced extension supracondylar fractures of the elbow in children treated during the first two years after the introduction of the following protocol; closed reduction under general anaesthesia with fluoroscopic control and lateral percutaneous pinning using two parallel pins or, when closed reduction failed, open(More)
Unstable degenerative spondylolisthesis of the cervical spine is very rare. Slip usually occurs at the C3 on C4 or C4 on C5 levels, immediately above a stiff lower cervical spine. There are two clinical patterns: that with neurological involvement causing cervicobrachial pain or myelopathy and that with neck pain alone. The diagnosis can be made by(More)
BACKGROUND The maintenance of horizontal gaze is an essential function of upright posture and global sagittal spinal alignment. Horizontal gaze is classically measured by the chin-brow vertical angle (CBVA), which is not readily measured on most lateral spine radiographs. OBJECTIVE To evaluate relations between CBVA and the slope of the line of sight, the(More)
Kingella kingae arthritis in children is now mainly diagnosed by PCR, which has surpassed conventional culture of joint fluid. As oropharynx colonization is the first step of Kingella kingae invasion, we prospectively investigated the possibility of cultivating it from throat swabs, in children hospitalized for K. kingae arthritis. Throat culture was(More)
Percutaneous epiphysiodesis using transphyseal screws (PETS) has been developed for the treatment of lower limb discrepancies with the aim of replacing traditional open procedures. The goal of this study was to evaluate its efficacy and safety at skeletal maturity. A total of 45 consecutive patients with a mean skeletal age of 12.7 years (8.5 to 15) were(More)
