Age, co-morbidity and co-medication are individual factors which can interfere with drug therapy. Relevant factors for planning and applying drug therapy for pain reduction are identified by literature review in correlation with clinical experience. Pitfalls are numerous and complex. Drug therapy has to be performed and monitored carefully. Strategies for risk reduction are outlined and clarified by examples. Good and safe pain reduction in elderly patients suffering from osteoporotic fractures usually depends on a transdisciplinary regimen.

Yet, experts usually lack a critical understanding of the limitations of their own powers of judgement. Although carefully developed and reliable approaches and procedures are available today to verify the validity of symptoms, these are often applied unwillingly. Despite sound base-rate estimates, cooperativeness in forensic evaluations is often accepted without proper critical assessment. In German speaking countries, more empirical research on civil forensic assessment would help to improve the quality of expert opinions. PMID: 20195570 [PubMed - as supplied by publish...

In addition to an acute stress reaction, adjustment disorders occasionally occur, while posttraumatic stress disorder is rarer; somatoform disorders, however, are frequent, especially persistent somatoform pain disorder and other psychological disorders. Since they defy objective substantiation, chronic complaints following whiplash injury give rise to numerous problems and differences of opinion. Therefore, medical appraisers require expertise not only in somatic, but also in psychological disorders.

Besides the application of different growth factors, new data in the literature suggest that cell therapeutic agents promote local bone regeneration. Due to ethical and biological considerations, clinical application of progenitor cells for the musculoskeletal system is limited to autologous postpartum stem cells. Here in particular, cell therapy with autologous progenitor cells in one surgical session has delivered first promising results.

After minor accidents the question often arises as to whether the occupant could really have been injured. The technical expert may calculate the biomechanical stress imposed on the occupants by the impact from the evidence gathered after the accident. Based on this data the medical expert is able to judge whether this stress was sufficient to produce the injury claimed. The threshold of biomechanical loading necessary for spinal injuries will be deduced from a technical perspective. With the help of examples, the steps required to preserve evidence will be explained.

Pain and cognitive deficits are the most commonly feigned medical complaints. However, the boundary between aggravation and/or malingering is generally not easy to identify. Relevant indications include discrepancies between the reported symptoms and the findings identified in the immediate post-trauma phase.

German and international publications are evaluated. Result: It was impossible to substantiate isolated injuries to alar ligaments. According to current knowledge, the published results are based on a misinterpretation of MRI findings. These results are to be considered as artefacts. There is no anatomical correlation for the classification of isolated injuries to alar ligaments. Surgical stabilisation due to an allegedly isolated injury to the alar ligaments is therefore not indicated. This statement does not apply to injuries sustained in high-speed trauma in combination with complex injuries of the atlanto-occipital and a...

Since then, there have been numerous scientific attempts to make a clearly defined profile of this injury. Unfortunately, these have all been unsuccessful. The discussion has not yet progressed beyond hypothetical approaches. The term "whiplash", which is such an impressive concept for those affected, still lacks any content. This gaping hole has provided enough scope for varied hypothetical explanations of why some people who have sustained whiplash, despite an initial absence of objective injury characteristics, develop a subjective complaints profile which becomes chronic! All too often, this profile tends to develop into an escalating third party legal dispute - further supported by sust...

In addition to adequate primary therapy, the appropriate choice of diagnostic procedures and treatment methods, which take the particular biomechanical characteristics of the individual fracture type into consideration, is essential for successful outcome and thereby the restoration of patient quality of life. In the case of a surgical indication, the procedure can be performed either in one or two sessions and can include dorsal, ventral or combined dorso-ventral spondylodesis.

Surgical interventions, therefore, include decompression, fusion, disc replacement or a combination thereof. Identifying the painful segment in the case of axial pain requires accurate segment diagnosis and may require invasive diagnostic measures (joint infiltration, discography), since imaging is often not fluid enough. In the case of fusion following disc removal, the placeholder is substitued in the form of a cage or autologous iliac crest graft. Alternatively, when dorsal elements are intact, a disc prosthesis can be inserted. In the case of compression, removal of the compromised structures (disc, osteophytes) becomes necessary.

This method of osteosynthesis facilitates local damage control surgery for fractures with extensive soft tissue injury and in polytraumatized patients. In addition, correction of deformities and bone segment transport are possible. Arthrodesis and septic surgery also benefit from external fixation.An extensive range of fixators and methods are available to meet these various needs. An external fixator consists of three elements: securing the bone fragments (pins and/or wires with extracorporeal ends), longitudinal rods and rings, and the connectors. The main features of external fixation can be described in terms of a few design and assembly principles. It is important that "form follows ...

Advances in the technical development of implants, including their material properties, have created the conditions for osteosynthetic procedures with minimal soft tissue disruption. The technical conditions of modern external fixator systems allow an unlimited number of assemblies matched to the requirements of each individual patient. Special changes in plate holes and interlocking nails have increased the angular and axial stability of the assembly and are particularly suitable for fractures with inferior bone quality, for example in the case of osteoporosis.

With the development of nails, which can be applied without reaming, the procedure lost importance. This publication presents the mechanical principles and impact of reaming on the bone. It describes how the pressure of the drill head and drill wave leads to a compression of medullary contents into the cortical vascular system. With the development of new drilling devices the direct effects of pressurization can be minimized and then become similar to those of unreamed intramedullary nailing. Lowering the pressure during reaming also prevents the formation ...

In most cases, the means of fixation are plates and screws. The goal is functional postoperative therapy by moving the adjacent joints and thus avoiding the deleterious disadvantages of long-lasting articular immobilization. Pre-operative planning, surgical approach, a good understanding of the precise mechanics of the structure and the biological answer for the various tissues are prerequisites of successful osteosynthesis. The choice of implants and the application of their versatility, as well as their adaptation to individual cases are the key to good results.

The essential criterion of manual medicine is inclusion of the segmental level of function. One criterion of evaluation is, most notably, segmental hypomobility. The purpose of manual diagnostics is to determine segmental blockage. Manual therapy techniques lead first to improved function of the segment and, consequently, to improved function of the whole organism.

Based on a detailed preoperative evaluation, differentiated surgical techniques, and many years of surgical experience very good cosmetic (97.6%) and good functional (68.4%) results can be achieved.

Instrumented gait analysis shows these problems best and provides the optimal base for the orthopaedic treatment. Modern therapy options consist of muscle lengthenings, muscle shortenings, corrections of torsions and stabilisations of joints. Especially at the foot level, conservative and operative means can be used depending on the individual situation. The aim is to rebalance muscle strength and length and to restore the lever arms. As many procedures as possible are combined in multilevel corrections in order to keep the total rehabilitation for the patient as short as possible.

The development of changes in muscle structure, muscle properties and muscle function carries the risk for the development of deformities and a deterioration in physical functions. Diagnostic and therapeutic measures should focus on muscular changes in particular. An interdisciplinary approach is recommended. The traditional orthopaedic management of deformity correction by muscle or tendon lengthenings always involves the risk of additional weakness. A more functional view of neuromuscular disorders should look at the 4 "M"s, i.e. muscle power, muscle excursion, muscle balance and muscl...

Orthoses support current concepts of therapy and are not forms of therapy in their own right. From this point of view orthoses are often used too late to prevent deformities. Efforts to standardize individual ortheses production and orthoses indication are showing initial success. The use of new materials has radically changed orthoses and further advances are expected with the use of electronic components, although this is still at early stages. For some years, particular attention has been paid to the evaluation and objective measurement of the effectiveness of orthoses. The future of orthotics lies in further specialization, st...

Furthermore, the current state of knowledge is illustrated by describing the results of a series of randomised controlled trials. Before the year 2000 nearly all German handbooks on orthopaedic and trauma surgery recommended unreamed intramedullary nailing as a more "biological" treatment that causes less harm to vascularity with equal or even better results. Unreamed nailing was in particular advocated for the treatment of open fractures.The tide turned as randomised controlled trials conducted since 2000 gave evidence that unreamed nailing leads to a higher rate of delayed or non-union, while the advantages to blood supply and infection rate could not b...

For this reason the diagnostician will be consistently surprised that there is a great multitude of different foot abnormalities and that not only the typical spastic talipes equines dominates. Of particular significance here is that these deformities almost always develop progressively, whereas most diseases persist per se, cerebral palsy being a typical case in point. However, in MMC (myelomeningocele) patients, there is also the danger of a worsening of the basic problem in the case of tethered cord syndrome.

However, a standardised injection strategy is still lacking. There is no doubt concerning the necessity for long-term therapy to cover the duration of motor development as well as for adequate prevention of fixed contractures. The appropriate dose and treatment concept to be used, however, is still controversial.

Revisions in particular are associated with a higher incidence of intra-operative fractures, specifically for the tibia and patella. Most fractures occur in the postoperative period with an average of 2-4 years after the primary procedure. Most commonly the femur is involved.

The main symptom is variably rapid, progressive muscle weakness, which leads to muscular imbalance and differently manifested impairment of motor functions. This results in the essential orthopaedic problems in these patients, e.g. contractures and deformities of the lower and upper extremities, foot deformities and sitting instability due to progressive scoliosis. Since the affected muscles have no physiological adaptability, they cannot be trained like healthy muscles. The orthopaedic treatment includes conservative metho...

If infection has occurred antibiotics and non-weight bearing are indicated. Abscesses and phlegmons can be localized by the clinical findings, ultrasound, x-rays, computer tomography and MRI and immediate surgical treatment is necessary to prevent further spreading.

Depending on the definition used, minor amputations can range from toe to Syme amputations. Minor amputations are often combined with necrosectomy and débridement. For early and optimal rehabilitation, as much vital tissue as possible should be conserved, especially considering the skeletal structures of the foot (borderline amputation). Minor amputations are of utmost importance for the prevention of ascending infections and reduce the duration of clinical and outpatient treatment.Minor amputations should be performed only by experienced surgeons and only if arterial perfusion is sufficient.

The current dogma is that if osteoblasts and endothelial cells grow and exhibit normal cell functions on these materials in vitro as single cultures or in co-cultures, then the biomaterials are suitable for implantation for bone reconstruction and regeneration. Generally, only in vivo animal studies will prove whether this is the case. However, in vitro studies offer a good pre-screening and selection basis to evaluate the biocompatibility of novel biomaterials prior to animal studies.

The perpetual regeneration processes allow continuous self-renewal and adaptation to prevailing mechanical forces. The complex regulation of osteoblastic differentiation during fracture repair has not been completely defined. Two different transcription factors - RUNX2 and SP7 - are considered to be master genes of osteoblastic differentiation. Furthermore, the canonical WNT pathway plays an essential role in the activation of osteoblastic differentiation during both bone growth and fracture healing.

Depending on the tissue type and the localization within the tissue, these cells may behave differently. Numerous studies have been done to compare articular, nasal, auricular, and costal chondrocytes in order to evaluate differences between knee and ankle joint cartilage and to investigate topographical variations within an articular joint. Moreover, the zonal structure of articular cartilage needs to be considered because it leads to phenotypical differences between chondrocytes of the superficial and the deeper zones. Several studies indicate, however, that even differentiated chondrocytes demonstrate a certain plasticity and strive to adapt their phenotypes t...

The further modification of classical ACT to matrix-associated autologous chondrocyte transplantation (MACT) includes the use of biomaterials as cell carriers and has biological and surgical advantages. The use of biomaterials as cell carriers for chondrocytes requires the analysis of cell culture conditions, cell-cell and cell-matrix interactions and also the determination of chondrocytic differentiation. The biomaterials used preserve the specific cellular architecture of chondrocytes and the combination of cultivated cells with biomaterials leads to the formation...

Therefore, researchers are attempting to develop alternatives using tissue engineering technology. The basic principle includes seeding of suitable cells on a resorbable carrier construct, in vitro biological and mechanical stimulation to generate a ligament-like extracellular matrix, and subsequent implantation as a cruciate ligament bioprosthesis.

During the last few decades a change of paradigm in treating non-specific low back pain has happened: physical activity and exercise therapy are now recommended as the first-line treatment in all relevant national and international guidelines. In chronic cases only biopsychosocial treatment concepts are successful, which have been introduced in Germany in 1990 in the form of the GRIP (Göttingen intensive low back program) for the first time. Meanwhile, this treatment has now been recommended by all evidence-based guidelines but we are still in the beginning of a full coverage care in Germany.

A paradigm change can be observed. Beginning in the 18th century orthopedic surgery became possible because of a change of the idea of man. Natural growth was seen as ideal solution in orthopedic surgery until the 19th century. Yet in the aftermath the point of view changed to a more technical determined approach. Until the middle of the 20th century the terms "efficieny" and "ability" became more and more important. Joint replacement with artificial materials was generally accepted and led to an enormous accelaration in the development of new materials and surgical techniques.

In addition, parkinsonian motor symptoms predispose individuals for orthopaedic diseases. PD patients have a higher risk of perioperative complications than patients without PD; this higher risk is based on motor and autonomous deficits in PD as well as on interactions between antiparkinsonian and anaesthesia medications. The elevated perioperative risk in PD can be reduced by appropriate perioperative management and no longer represents a contraindication to surgery in PD patients.

In cases of possible infection, the surgeon must have a treatment concept that can be individually adjusted. Diagnosis is a challenge and should include a variety of investigations. In early and secondary infections, component retention can be successful. Surgical debridement is the key to success. All late and chronic infections should be treated by explantation of all components because of infection with biofilm-producing microbes.

Even for identical materials and geometries, the interaction of those parameters can generate different numbers of particles as well as different particle sizes and shapes. These different wear-particle characteristics will directly influence the biological response to an implant and thereby its clinical success. The long-term success of a total joint replacement requires an optimized compromise among implant material, design, surgical procedure, and biological performance.

They are more likely in S-heads with reduced ceramic thickness between the tip of the taper and the surface. Failures of ceramic inlays have been seen especially in sandwich type inlays or in cup designs with reduced range of motion causing impingment of the neck. The precise positioning of the cup is therefore of major importance.In cases of fractured ceramic implants, CoCr-heads or PE-inlays are commonly used. The use of stainless steel heads in revision surgery due to ceramic fractures is obsolete.

Disorders of muscle activity and lack of weight bearing due to neuromuscular diseases may cause clinical symptoms such as an unstable hip or reduced range of motion. Disability and handicap because of pain, hip dislocation, osteoarthritis, gait disorders, or problems in seating and positioning are dependent on the severity of the disease, the time of occurrence, and the means of prevention and treatment. Preservation of pain-free and stable hip joints should be gained by balancing muscular forces and by preventing progressive dislocation.

Analogous to increased activity of external or internal rotator muscles codetermined by the palsy, increased external or internal humeral torsion occurs. External torsion deformity was associated with a smaller range of motion and seemed to have a greater importance for routine daily activities (e.g. muscle force, sports ability) than internal torsion deformity.

Ruptures of the MCL can also be treated conservatively in complex injuries if the cruciate ligaments are reconstructed. Ruptures of the lateral structures usually need surgical reconstruction.

The disease most frequently affects the knee in men, followed by the elbow. The basic feature of this disease is a metaplastic maturation of the mesenchymal cells in the synovial membrane of a joint into cartilage. These cells mature into chondroblasts and form small nodules of cartilage in the synovial membrane. These nodules subsequently enlarge and detach to lie within the joint space. They become free within the joint as multiple small cartilaginous loose bodies nourished by the synovial fluid.

Pros and cons are pointed out for both conservative and operative therapy. Getting out of his wheelchair a 59-year-old patient with chronic spinal cord injury suffered a lower leg fracture. Minimally invasive elastic stable intramedullary nailing (ESIN) was performed to gain sufficient stability for physiotherapy. The follow-up yielded excellent clinical and radiological results. ESIN is an adequate therapeutic alternative for lower leg fractures in patients with chronic spinal cord injury.

The complication rate is low, and if the correct technique that respects the blood supply is used, femoral head necrosis does not occur. The most frequent complications are minor ectopic bone formation and nonunion of the greater trochanter. Surgical treatment includes the correction of femoral and acetabular pathology. Clinically, in approximately 75-80% of cases a good-to-excellent result can be obtained.

The patients' age, history, and physical examination may lead to the correct diagnosis. Plain radiographs are the imaging modality of first choice. In addition to obvious findings, more subtle changes such as loss of offset at the head-neck transition or acetabular retroversion have to be assessed. For correct analysis, a high quality of the images must be ensured. Therefore, knowledge of the technique used to take the pictures seems essential.

Both osseous deformity and use of the hip may result in hip damage. Osseous deformities are seen on the acetabular (pincer) or the femoral (cam) side of the hip, leading to characteristic alterations of the acetabular rim. Cam FAI is found in 20-30-year-old athletic men, revealing deep cartilage avulsions from the acetabular rim while the labrum is frequently intact. In pincer FAI, found in 30-40-year-old women, the labrum is frequently significantly destroyed with only minor damage to the acetabular rim.

It is now taken very seriously and recognised as a national and global disorder which is both preventable and treatable. In spite of this progress, in Europe and especially in Germany, osteoporosis remains an underdiagnosed and undertreated disease.

It is seldom intraarticularly localized and presents nonspecific signs and symptoms, such as swelling, slight warmth, and nocturnal pain. Because of unusual clinical findings and the frequent absence of typical bone sclerosis, diagnosis often takes longer than for extraarticular osteoid osteoma. Complete arthroscopic en bloc excision of the lesion is the treatment of choice, offering complete relief of symptoms following surgery.

However, treatment failures are common and comparable to other therapeutic approaches. Therefore, conservative treatment must be discussed critically. Healing with residual defect must be regarded as a good treatment result, and additional operative procedures with the objective of radiographic cosmetics should not be done. Because of poor results and long-term disability related to weight bearing, treatment of UBCs with cannulated screws cannot be recommended in lesions located in the proximal femur.

The treatment should be restricted to osteolytic lesions of the vertebral body, and only if a relevant mechanical deterioration is present. If the pedicles and/or the lamina are involved and if there is compression of the spinal canal, the treatment is no longer appropriate.
