Functional and radiographic consideration of lower limb malalignment in children and adolescents with idiopathic genu valgum.

Three-dimensional gait analysis is capable of assessing dynamic load characteristics and the resulting compensatory effects of lower limb malalignment, which are generally not reflected in static imaging. This study determined differences in gait parameters in the frontal and transverse plane between patients and controls in order to identify compensatory mechanisms, and to correlate radiographic measurements and gait parameters in a consecutive series of children with idiopathic genu valgum. Thirty-three patients (mean age 12.

Long-term results of a nationwide general ultrasound screening system for developmental disorders of the hip: the Austrian hip screening program.

Background: Diagnosis and early treatment of developmental dysplasia of the hip (DDH) continue to be issues of discussion. In 1992, a nationwide general ultrasound screening program using Graf technique was introduced to detect DDH in Austria. We investigated the effects of this program on the rates of operative and conservative interventions and the influence of the program on the number of hospital admissions for the treatment of DDH.

Wrist arthroscopy in children and adolescents: a single surgeon experience of thirty-four cases.

Purpose: The purpose of this study was to report our experience of wrist arthroscopy in children and adolescents with chronic wrist pain in a retrospective single surgeon series. Therefore, technical differences or obstacles compared to standard wrist arthroscopy in adults, and complications were highlighted.

Methods: A retrospective data review of all patients undergoing wrist arthroscopy between 2002 and 2011 was performed.

Does open reduction of the developmental dislocated hip increase the risk of osteonecrosis?

Background: Osteonecrosis (ON) of the femoral head is one of the main complications associated with treatment of developmental dysplasia of the hips (DDH). The reported rates of ON vary widely between 6% and 48%, suggesting varying factors in these studies influence the rate. Several studies suggest open reduction combined with femoral shortening provides protection against ON.

Outcome of painful bone marrow edema of the femoral head following treatment with parenteral iloprost.

Background: Bone marrow edema (BME) is a common cause of hip pain. The aim of the study was to assess the efficacy of the vasoactive drug iloprost in the treatment of BME of femoral head.

Materials And Methods: We reviewed 27 patients (19 male, 8 female) with BME of the femoral head.

Correction of post-traumatic lower limb deformities using the Taylor spatial frame.

Twenty-five post-traumatic leg length discrepancies combined with axial deviation in 22 patients were treated with the Taylor spatial frame. We retrospectively analysed the accuracy of correction, the complication rate and the clinical outcome including the duration of treatment. The cases were divided into three sub-groups according to the level of the osteotomy.

Neurogenic hip dislocation in cerebral palsy: quality of life and results after hip reconstruction.

Background: At birth, no difference exists between the hips of children with spastic cerebral palsy and the hips of other children. The typical pathologic deformities of the hips in children with spastic cerebral palsy develop as the child gets older. One of our goals was to evaluate the change in quality of life of children with cerebral palsy after hip reconstruction.

Balloon kyphoplasty for vertebra plana with or without osteonecrosis.

Purpose: To compare efficacy of balloon kyphoplasty in restoring vertebral height and correcting kyphosis in patients having vertebra plana with or without osteonecrosis.

Methods: 12 women and 3 men (mean age, 76 years), who had a complete vertebra plana with or without osteonecrosis (n=8 vs n=7), underwent balloon kyphoplasty. No external manoeuvres were performed before or during balloon kyphoplasty, except for positioning the patients in a prone posture on the operating table.

Natural course of intra-articular shifting bone marrow edema syndrome of the knee.

Background: Intra-articular shift (migration) of bone marrow edema syndrome (BMES) is a very rare disease. Only a few cases have been reported thus far. The condition may cause the clinician to suspect an aggressive disease.

Tapping test in patients with painful bone marrow edema of the knee.

Background: Although bone marrow edema (BME) of the knee is a common phenomenon, physical tests to diagnose this condition have not been investigated. We hypothesized that a mallet test would be useful as a diagnostic aid and a screening tool.

Methods: Seventy patients (36 female, 34 male) were investigated in this controlled study.

Accuracy of complex lower-limb deformity correction with external fixation: a comparison of the Taylor Spatial Frame with the Ilizarov ring fixator.

Purpose: Circular external fixators have several advantages over other surgical options in the treatment of limb length discrepancy and axial deformity. The innovative Taylor Spatial Frame (TSF) combines a rigid hexapod fixation system with the support of a web-based software program, and thus offers the possibility of simultaneous corrections of multidirectional deformities. Whilst there is still some scepticism of many Ilizarov device users about the advantages of the TSF, the purpose of the study was to perform a comparison between the TSF and the Ilizarov ring fixator (IRF) with regard to the accuracy of deformity correction in the lower limb.

Is there an indication for prophylactic balloon kyphoplasty? A pilot study.

Vertebroplasty and kyphoplasty are associated with a recurrent fracture rate of 2.4% to 23%, which is lower than the general natural history of untreated osteoporotic fractures. Some authors suggest the risk of refracture at adjacent vertebra will be reduced by prophylactic stabilization.

The "cruciate suture" for arthroscopic meniscal repair: a new technique.

Meniscal repair has become the treatment of choice whenever a reparable tear is diagnosed. Fixation strength of the repair technique is always of paramount importance in comparison of various techniques, especially after the evolution of many arthroscopic all-inside devices. We present a new arthroscopic meniscal repair suturing technique called "cruciate suture.

Knee deformity in congenital longitudinal deficiencies of the lower extremity.

Unlabelled: The knee has various pathologic appearances in patients with congenital longitudinal deformities of the lower extremities. Radiographs from 39 patients with unilateral longitudinal congenital deficiencies of the lower extremities were analyzed to describe epiphyseal and metaphyseal configurations and position of the epiphyseal plate. We defined 22 radiographic parameters of the femur and tibia, calculated the mean values, and compared the parameters of the affected knee with the unaffected knee for patients in different age groups.

Dysplasia of the cruciate ligaments: radiographic assessment and classification.

Background: A common pathologic finding in the knee associated with congenital longitudinal deformity is aplasia of one or both cruciate ligaments. We performed a radiographic analysis to assess the changes in the femoral intercondylar notch and the tibial eminence in relation to the status of the cruciate ligaments.

Methods: Thirty-four knees in thirty-one patients with longitudinal congenital deficiency of the lower limb were evaluated.

Poor agreement between prospective and retrospective assessment of hallux surgery using the AOFAS Hallux Scale.

Background: Retrospective assessment of preoperative status is common in nonprospective study designs. The aim of this study was to test the hypothesis that prospective and retrospective evaluations of the preoperative patient condition in hallux surgery gives equal results and therefore can be used interchangeably.

Methods: One hundred and fifty-nine consecutive feet with hallux surgery were analyzed prospectively.

Cementless total hip arthroplasty using a threaded cup and a rectangular tapered stem. Follow-up for ten to 17 years.

We carried out a clinical and radiological review of 103 cementless primary hip arthroplasties with a tapered rectangular grit-blasted titanium press-fit femoral component and a threaded conical titanium acetabular component at a mean follow-up of 14.4 years (10.2 to 17.

Tribological considerations for a new hip system.

Purpose Of The Study: This paper was initiated to evaluate a new total hip system based on cementless fixation and focusing options for different articulations within a single hip system.

Material And Methods: 100 patients provided with the cementless Variall hip system were evaluated clinically and radiographically. The 59 female and 41 male patients were followed for a minimum of 3 years postoperative.

Treatment options for developmental dislocation of the hip after walking age.

Cases of developmental dislocation of the hip occur after walking age because of late or missed diagnosis and failed conservative or operative treatment. Although a general consensus exists for the treatment in infants up to the age of 18 months, the recommendations for the treatment of developmental dislocation of the hip in older children range from conservative treatment up to 3 years of age to primary surgical procedures from the age of 18 months. A review of the pertinent literature and of the different treatment options was performed and the authors' preferred treatment regime and techniques for the operative treatment of developmental dislocation of the hip after walking age are reported.

Treatment of reflex sympathetic dystrophy in children using a prostacyclin analog: preliminary results.

Unlabelled: The aim of our study was to evaluate Iloprost, a prostacyclin analog, for treatment of reflex sympathetic dystrophy in children not responsive to conservative treatment. Seven female patients with a mean age of 9 years (range, 6-11 years) diagnosed with reflex sympathetic dystrophy Stage II were treated with infusions of Iloprost given on three consecutive days. Additionally, all patients had physiotherapy and were offered psychologic consultation.

A new arthroscopic technique for revision of the posterior compartment in symptomatic total knee arthroplasty.

Arthroscopy is effective in treating the symptomatic knee following total knee arthroplasty. A small number of patients complain about postoperative pain in the posterior compartment. Loose bodies and degenerated remnants of the menisci are the main reasons for this pain.

Pathomorphology and treatment of congenital anterolateral bowing of the tibia associated with duplication of the hallux.

Congenital unilateral anterolateral tibial bowing in combination with a bifid ipsilateral great toe is a very rare deformity which resembles the anterolateral tibial bowing that occurs in association with congenital pseudarthrosis of the tibia. However, spontaneous resolution of the deformity without operative treatment and with a continuously straight fibula has been described in all previously reported cases. We report three additional cases and discuss the options for treatment.

A new soft transglenoidal suture anchor for arthroscopic labrum fixation.

Inherent in most transglenoidal suture stabilization techniques of unstable shoulders is the unreliable fixation of posterior knots on the fascia. The transglenoidal suture anchor (TSA) technique overcomes this disadvantage. The TSA is a 1.

Comparison of debridement versus suture in large rotator cuff tears: long-term study of 64 shoulders.

Introduction: The goal of this study is to determine whether suturing is superior to non-closure in terms of the subjective long-term outcome in large rotator cuff tears.

Materials And Methods: A total of 64 shoulders with rotator cuff tears of at least 3 cm diameter and followed up for a mean period of 5 years and 8 months were retrospectively examined. The patients' medical history, clinical findings, radiographs and Constant scores were studied.
