[Physiotherapeutic and rehabilitative options for neuromuscular scolioses : Areas of physiotherapy techniques in the field of tension between hypertonic and hypotonic forms of neuromuscular scoliosis].

Conservative treatment and physiotherapy (PT) of neuromuscular scoliosis and its underlying systemic causes is dominated by a pragmatic approach. In the choice of treatment, the observance of the underlying muscle tone sets the essential course to select an appropriate PT technique. Hypertonic forms need the reflex-modulation techniques included in Bobath or Vojta programmes.

[Orthopaedic technology and neuromuscular scoliosis : Orthotics, wheelchair seating shells and positioning aids].

Children and adolescents with neuromuscular scoliosis usually undergo severe challenges with their respiratory and locomotor systems during growth. Early onset scoliotic deformities take a whole team of specialists to ease the problematic side effects associated with poor posture and seating abilities. Wheelchairs and seating shells need to be adjusted as does suitable bracing for the collapsing spine.

Three-dimensional acetabular orientation during periacetabular osteotomy: a video analysis of acetabular rim position using an external fixator as navigation tool during reorientation procedure.

Introduction: Bernese periacetabular osteotomy is an effective procedure for treating acetabular dysplasia. However, limited visual control of the acetabular position during surgery may result in under- or overcorrection with residual dysplasia or femoroacetabular impingement. Thus, we wanted to find a simple method to control the effect of correction in the sagittal and coronal plane.

[Conservative and surgical treatment of idiopathic scoliosis].

Idiopathic scoliosis is the largest group of all forms of scoliosis in the growth phase accounting for 80-90%. A distinction is made between idiopathic infantile (0-3 years), juvenile (4-10 years) and adolescent scoliosis (>10 years), depending on the age when scoliosis appears. The treatment depends on the skeletal age, the Cobb angle and the progression behavior of scoliosis.

A Knee Size-Independent Parameter for Malalignment of the Distal Patellofemoral Joint in Children.

Introduction: Patellar instability (PI) is a common finding in children. Current parameters describing patellofemoral joint alignment do not account for knee size. Additionally, most parameters utilize joint-crossing tibiofemoral landmarks and are prone to errors.

[Treatment recommendations for protracted hip immaturity in infants : Conservative approach versus open reduction].

The healthy upright posture is a result of a continuous maturation process of the locomotor system throughout skeletal growth rendering muscle strength and stability: The hip joint in its central position plays a key role for unimpaired and pain-free gait. Nonetheless, it is also regularly affected by delayed maturation, thus being of special interest for the disease screening procedures of every newborn child. Structured screening examinations in the first 3 postnatal months will ideally detect any dysplasia, therefore simple conservative interventions will usually accelerate the maturation process.

Assessment of pelvic tilt in anteroposterior radiographs by means of tilt ratios.

Introduction: In anteposterior (AP) radiographs, cup position in total hip arthroplasty and acetabular anatomy in hip-preserving surgery are highly influenced by pelvic tilt. The sagittal rotation of the anterior pelvic plane is an important measurement of pelvic tilt during hip surgery. Thus, correct evaluation of cup position and acetabular parameters requires the assessment of pelvic tilt in AP radiographs.

Rotation of intramedullary alignment rods affects distal femoral cutting plane in total knee arthroplasty.

Purpose: Intramedullary rods are widely used to align the distal femoral cut in total knee arthroplasty. We hypothesised that both coronal (varus/valgus) and sagittal (extension/flexion) cutting plane are affected by rotational changes of intramedullary femoral alignment guides.

Methods: Distal femoral cuts using intramedullary alignment rods were simulated by means of a computer-aided engineering software in 4°, 6°, 8°, 10°, and 12° of valgus in relation to the femoral anatomical axis and 4° extension, neutral, as well as 4°, 8°, and 12° of flexion in relation to the femoral mechanical axis.

[Disease-specific Knowledge in Conservative Treatment of Adolescent Idiopathic Scoliosis].

Background: The typical onset of adolescent idiopathic scoliosis falls in a sensitive stage of life. Nevertheless, conservative brace treatment requires a high degree of compliance. Disease-specific knowledge influences therapy outcome in many diseases and potentially improves patient compliance and quality of life.

[Conservative treatment of idiopathic scoliosis : Influence of archetypical Cheneau-Corsets on trunk asymmetry].

Background: The vertical posture of the growing child requires minute central nervous control mechanisms to maintain the symmetry of the torso in its various activities. Measuring only static parameters such as the Cobb angle does not describe the dynamic changes of scoliotic deformities in gait. A constant deviation in the frontal, transverse, and sagittal planes from the dynamic symmetry of the trunk is described in motion analysis and the surface changes of the spinopelvic complex.

Current therapeutic strategies of heterotopic ossification--a survey amongst orthopaedic and trauma departments in Germany.

Background: Heterotopic ossification (HO) is a complication after tissue trauma, fracture and surgery (i.e. total hip arthroplasty).

[Surgical treatment of scoliosis in childhood and adolescence: Age group and etiology-related indications and choice of instrumentation].

The indications for a corrective surgical procedure for the complex 3-dimensional deformations of the spine collectively known under the term scoliosis, essentially depend on knowledge of the underlying etiology, the time of initial diagnosis in relation to the growth curve of the child and on considerations about the general operability of the patient. An early onset of scoliosis in childhood under defined diagnostic criteria is usually associated with a fast progression of spinal curvature and requires early surgical intervention during the growth period, while scoliosis in adolescence often allows a delayed surgical intervention until all conservative means have been taken into consideration. Corrective measures in the growing spine require procedures and adjustable hardware which can be adapted to vertebral and thoracic growth and thus anticipate the threat of pulmonary insufficiency due to postural and spinal collapse.

[Lumbar spinal stenosis. From diagnosis to correct therapy].

The number of patients with a diagnosis of lumbar spinal stenosis (LSS) is steadily increasing and the expectations of patients are high; however, valid data for an appropriate therapy are lacking. Treatment is mostly the result of the surgeon's experience and the clinical focus. The findings in magnetic resonance imaging (MRI) often do not correlate with the patient's symptoms.

Transition metal complexes containing the S(NtBu)4(2-) tetraimidosulfate dianion.

Three novel metal complexes [(acac)2Cu2(NtBu)4S] (), [Li(thf)4]2[I4Cd2(NtBu)4S] () and [(thf)2Li{(SiMe3)2N}Zn(NtBu)4S] () are prepared from the intended transmetalation of the dilithium complex of N,N',N'',N'''-tetrakis(tert-butyl)tetraimidosulfate [(thf)4Li2(NtBu)4S] (). The two lithium cations are replaced by either the cationic (acac)Cu(ii) moiety, the neutral I2Cd(ii) residue or only a single lithium cation is substituted by the cationic (Me3Si)2NZn(ii) fragment. The complexes show two main results: first the S(NtBu)4(2-) tetrahedron can serve as a ligand to transition metals from the soft Cu(ii) to the harder Zn(ii) at opposite sides and second the S-N bond distances vary only marginally in response to the various metals and the four distances constantly sum up to 6.

[Conservative treatment of idiopathic scoliosis with effective braces: early response to trunk asymmetry may avoid curvature progress].

Vertical posture of the growing child requires minute central nervous control mechanisms in order to maintain symmetry of the torso in its various activities. Scoliosis describes a constant deviation in the frontal, transverse and sagittal planes from the dynamic symmetry of the trunk. Early intervention with effective bracing, physiotherapy and sports can reverse curve progression during growth spurts, once these are identified in screening.

[Flexible flatfoot in children: variation within normal range or need for treatment?].

Flexible flatfoot in childhood is a common cause for repetitive consultations and the diagnosis is verified by the clinical examination. In most cases the findings are age-dependent variants of the norm and if asymptomatic there is no need for treatment. In the first decade of life symptomatic flexible flatfoot should initially be treated with shoe inserts.

Oxidative addition versus substitution reactions of group 14 dialkylamino metalylenes with pentafluoropyridine.

Dialkylamino compounds of group 14 elements (Si, Ge, Sn) in the +2 oxidation state supported by benzamidinate ligands were synthesized and treated with pentafluoropyridine. Two different modes of reactivity were observed, depending on the metal atom and the basicity of the substituent at the metal. Pentafluoropyridine undergoes oxidative addition reaction at the Si(II) and Ge(II) atoms whereas at the Sn(II) atom substitution of the NMe(2) group by the para fluorine of pentafluoropyridine occurs.

Stable silaimines with three- and four-coordinate silicon atoms.

The reactions of silylenes with organic azides are quite diverse, depending on the substituents of the silylene center and on the nature of the azide employed. Elusive silaimine with three-coordinate silicon atom L(1)SiN(2,6-Triip(2)-C(6)H(3)) (5) {L(1) = CH[(C═CH(2))(CMe)(2,6-iPr(2)C(6)H(3)N)(2)] and Triip = 2,4,6-triisopropylphenyl} was synthesized by treatment of the silylene L(1)Si (1) with a sterically demanding 2,6-bis(2,4,6-triisopropylphenyl)phenyl azide (2,6-Triip(2)C(6)H(3)N(3)). The reaction of Lewis base-stabilized dichlorosilylene L(2)SiCl(2) (2) {L(2) = 1,3-bis(2,6-iPr(2)C(6)H(3))imidazol-2-ylidene} with Ph(3)SiN(3) afforded four-coordinate silaimine L(2)(Cl(2))SiNSiPh(3) (6).

[Treatment of patellar instability in children and adolescents].

To address recurrent patellar instability in children and young adolescents a variety of therapeutic options exist either as non-operative or operative treatment. Recent options, such as reconstruction of the medial patellofemoral ligament have evoked a new focus of attention on this topic. The intention of this article is to present diverse therapeutic options and to evaluate them by reference to the current literature.

[Clinical pathway - conservative back pain treatment].

Back pain is a very common clinical picture. The causes are often not only somatic, which generally has led to a biopsychosocial understanding of this disease. Therefore, it is necessary to employ a multimodal treatment approach to achieve effective and longer-lasting relief.

[Orthotic methods for osteoporosis and osteoporotic vertebral fracture].

Even in times of kyphoplasty and vertebroplasty, braces remain an efficient option in the treatment of osteoporotic hyperkyphosis due to imminent or manifest vertebral wedging with the obligatory pain and fracture risk of adjacent vertebraes. In the same fashion, acute osteoporotic fractures with considerable backpain can be treated with an adequate orthosis besides analgetics and osteological drugs. Essential is the careful selection of the right brace for a given type of osteoporotic fracture: Overall brace-frames (Stagnara type) should be used only in highly unstable or multiple osteoporotic fractures with impact onto the spinal canal where surgery is not possible.

[Minimally invasive injection therapy for patients with radicular lumbar spine syndrome. First results of an minimally invasive treatment for patients with lumbar radiculopathy].

Background: There are few studies on minimally invasive injection therapy (MIT) combined with multimodal conservative therapeutic options. Here, we evaluate the results of MIT in a clinical study.

Methods: A total of 61 patients with radicular lumbar symptoms treated with MIT were examined before and 14.
