Biomechanical evaluation of temporary epiphysiodesis at the femoral epiphysis using established devices from clinical practice.

The aim of this study is to compare biomechanical features of different devices used in clinical routine for temporary epiphysiodesis (eight-Plate® and FlexTack). The tested implants were divided into four different groups (eight-Plate® vs. FlexTack for lateral and anterior implantation) á 10 samples for testing implanted eight-Plate® vs.

Endoscopic facet joint denervation for treatment of chronic lower back pain.

Objectives: Percutaneous radiofrequency is an established method for treatment of chronic low back pain of intervertebral facet etiology. Endoscopic techniques have the advantage of visualization of the facet joint and the dorsal medial ramus and thus allow for more accurate denervation. It was thus hypothesized that pain reduction is vaster and longer enduring.

Treatment with and without stabilizing lumbar spinal orthosis after one- or two-level spondylodesis: A randomized controlled trial.

Background And Objective: Musculature affected during spondylodesis surgery may benefit and recover faster if supported by spine orthosis postoperatively.

Methods: This prospective study included 50 consecutive patients undergoing one- or two-level spondylodesis. The intervention group received a lumbar spine orthosis (n= 23), while the control group remained without orthosis (n= 27).

Proximal Femoral Osteotomies in the Adolescence: Indications and Treatment Strategies.

Proximal femoral osteotomies are common surgical interventions to treat hip deformities in pediatric orthopedics. The aim of proximal femoral osteotomies is to optimise hip containment by using varus or valgus osteotomy, flexion or extension osteotomy with shortening, lengthening or derotation of the femoral neck. Furthermore improved muscular dysbalance by enhancing the femoral offset, extension of the range of motion and pain reduction are important surgical intentions.

The Phenomenon of the Apparent (Double) Femoral Head in Infant Hip Sonography According to Graf-Description, Incidence and Clinical Relevance.

Purpose: Hip screening sonography according to Graf in rare cases yields the appearance of a double femoral head, aptly named the Double-Head-Sign. The goal of this retrospective study is to offer a definition of this rare sign, evaluate its incidence of occurrence and compare the sonographic findings with the clinical findings.

Materials And Methods: This Double-Head-Sign is caused by the overlap of the trochanter major with the actual head of the femur in cases of coxa vara.

The Kellgren and Lawrence Score as a helpful tool for the indication for total disc replacement at the cervical spine.

Background: Several studies showed encouraging results after total disc replacement (TDR) in patients with cervical-brachial syndrome (CBS).

Objective: The aim of this study was to supplement the existing documentation of results after total disc replacement and to underline the importance of the correct indication.

Methods: The clinical and radiological outcome of 34 patients was evaluated in a 2-year follow-up by several parameters as the Visual Analogue Scale (VAS) for pain, the Neck Disability Index (NDI) and the Kellgren and Lawrence Score.

A novel PLIF PEEK interbody cage with an impactionless insertion technology: A case series with a mid-term follow up of three years.

Background: Spinal fusion surgery has become one of the most common spinal procedures during the recent years. Searching for an optimum structural stability of the vertebral interspace, surgical implants which can be inserted via a posterior lumbar interbody fusion (PLIF) approach have been enhanced recently.

Objective: Evaluation of safety and efficacy of a novel PLIF polyetheretherketone (PEEK) interbody cage (TWIST) with an impactionless insertion technique.
