Abstract
Minimally invasive injection treatment is indicated particularly in cases of treatment-resistant, painful degenerative alterations of the cervical and lumbar spine, intervertebral disc displacement and radicular syndrome. Through the injections and the supplementation with further conservative, e.g., physical therapy and activating measures, the vicious circle of neural irritation and muscle tension and sympathetic nerve reactions can be interrupted.

Abstract
An intensive conservative treatment that exhausts all treatment options should fundamentally be carried out before every surgical intervention in the region of the spinal column. The therapeutic measures are determined by the extent of the cervical or lumbar syndrome. As a rule, in cases of local complaints symptomatic measures with physiotherapy or digital healthcare applications are indicated. In cases of referred cervical and lumbar syndromes targeted injections can be employed. Before targeted injection treatment a detailed orthopedic clarification with respect to the intensity of local, radicular or pseudoradicular complaints must be carried out. When carrying out minimally invasive injection treatment specific prerequisites with respect to spatial, personnel and technical conditions must be fulfilled. The indications and contraindications must be strictly controlled.

Abstract
Achilles tendon pathologies are a frequent problem in the clinical practice. A distinction must be made between insertional and noninsertional tendinopathies. In addition to intrinsic risk factors, such as diabetes mellitus, there are also extrinsic risk factors, such as overuse and running. Sonography, X‑ray imaging and magnetic resonance imaging (MRI) are established imaging methods, depending on the question. The primary treatment includes a conservative approach. First-line treatment includes administration of nonsteroidal anti-inflammatory drugs (NSAID), physical rest and the use of assistive devices. Established conservative treatment procedures include eccentric stretching, shockwave therapy and infiltration with, e.g., platelet-rich plasma. There are numerous other conservative treatment options. After exhausting the conservative treatment options, a surgical approach can be considered. The surgical procedure depends on the clinical symptoms and findings. Established procedures are minimally invasive or endoscopic procedures or even open debridement.

Abstract
The ankle joint has to bear the entire body weight on a relatively small joint surface. Incongruities, instabilities and deformities lead to painful arthrosis and considerable restrictions in everyday life. For many years, arthrodesis has proven to be the gold standard for end stage arthrosis; however, considering modern endoprostheses for the ankle joint it is no longer appropriate to offer only arthrodesis. The very good results of the 3rd generation 3‑component prostheses and the 4th generation 2‑component prostheses show how much the surgical treatment options for the ankle joint are currently changing. The simplified implantation techniques enable access to arthroplasty of the ankle joint for a broader spectrum of surgeons and explain the increasing implantation rates in recent years. Decisive for postoperative success are correct planning with knowledge of the leg axes and foot position, correct patient selection and exact surgical placement of the components.

Abstract
The treatment strategies for focal cartilage damage in the knee are multifarious. For established procedures, such as microfracturing (MFX), autologous matrix-induced chondrogenesis (AMIC), osteochondral transplantation (OCT) and autologous chondrocyte transplantation (ACT), well-founded, partly comparative long-term studies and overlapping size-dependent differential indications are available. Innovative cell sources, the utilization of biological scaffolds as well as biologic agents and various combinations, have recently become the focus of scientific attention; however, high regulatory demands are restricting their use in Germany. The success of every procedure is dependent on the appropriate indications, the treatment of comorbidities, such as axis deviations or ligamentous instability, the surgeon's experience and an adequate follow-up treatment.

Abstract
Infections are a severe complication after an artificial joint replacement. The clinical symptoms are highly variable, particularly in patients with inflammatory rheumatic diseases, which often makes the diagnosis difficult. In addition to clinical and laboratory findings, joint puncture is an essential component of the diagnostics and enables the identification of pathogens. Treatment of periprosthetic infections in patients with rheumatism should be an interdisciplinary cooperation between surgeons, rheumatologists and specialists for infectious diseases. The two essential pillars of treatment are surgical intervention and antibiotics. For acute joint infections an attempt at preservation of the artificial joint can be carried out, whereas for chronic infection situations only replacement of the prosthesis is possible as a curative treatment. In order to reduce the probability of occurrence of a joint infection, modifiable risk factors should be preoperatively identified and specifically treated.

Abstract
Nerve compression syndromes of the upper extremities are relatively frequent diseases, the timely detection and treatment of which can prevent irreversible damage in the sense of muscle atrophy and subsequent paresis. The medical history and clinical examination play an important role in determining the suspected diagnosis. The subsequent neurological examination then serves to confirm the suspected diagnosis. This article provides a comprehensive overview of the etiology, pathogenesis, symptoms and treatment of the disease.

Abstract
The X‑ray image-guided injection methods are an important tool for the treatment of cervical and lumbar pain syndromes. For the application of these methods it is necessary to have a differentiated consideration of cervical and lumbar pain syndromes. This leads to a decoding of complaints to assignable pain generators, which enables a targeted injection method. Depending on the origin of pain, injections are placed at the nerve root or the joints. Thus, the vicious cycle of pain can be stopped. A correct technical procedure is of enormous importance. Particular attention must be paid to the pharmacological effects and special complications. A monitoring and precautionary measures are mandatory.

Abstract
BACKGROUND After total hip arthroplasty (THA), objective postoperative quality control is done via X‑rays by as component position assessment. The cup position is defined by its version and inclination. However, there is a discrepancy between radiographically measured and true (anatomic) cup position, which may lead to misinterpretation. METHODS To visualize the discrepancy between true and radiographically measured cup position, in this video, a cup holder was used to set the angular cup version and inclination. Hereby, the cup position (anteversion and inclination) can be characterized in its radiographic and anatomic definition in greater detail. The viewer of this video should receive an impression as to when radiographically measured cup angles must be considered with caution. RESULTS In a simultaneous X‑ray and image sequence, this video shows decreased radiographic inclination measurement with increasing anterior rotation of the cup exceeding 20° of anteversion, yet with unchanged true inclination on the cup holder. Isolated consideration of the radiographic angles of anteversion and inclination may cause misinterpretation of true cup position. In pectoral illustration we show that variations in cup version and inclination may remain undetected when considering isolated the radiographic cup parameters. CONCLUSION True cup position in its anatomical definition can be calculated from the radiographically measured position. For this purpose, both cup parameters (radiographic anteversion and radiographic inclination) have to be taken into account.

Abstract
BACKGROUND Sagittal balance is dependent on a complex interplay of the spinal curves, shape and setting of the pelvis, but also the position of the joints of the lower limb. Degenerative processes such as stiffening of the spine, aging of musculature, or reduction of the range of motion of the joints lead to imbalance of the spine after all compensatory mechanisms have been exhausted. OBJECTIVES Based on standardized imaging, compensation mechanisms must be identified within a biomechanical analysis of the spine, the original sagittal spine profile anticipated and included in the planning of the corrective intervention. RESULTS This review presents the most important global and spinopelvic parameters for the biomechanical analysis of the spine. In addition, normal variations of the sagittal alignment are discussed, compensation mechanisms are shown, and the planning of the rebalancing of the sagittal alignment is shown according to the full balance integrated model.

Abstract
The hallux valgus deformity is the most common toe deformity of the forefoot and is often associated with a splayfoot. Malpositioning of the small toes may be isolated but are more common in other foot deformities. The understanding of the complex pathoanatomy of the foot is necessary for orthopedic treatment. Conservative treatment is reserved for the early stages. The indications for surgery should be based on clinical and radiographic findings. Countless surgical procedures are available and minimally invasive surgical techniques are also increasingly being used.

Abstract
BACKGROUND Therapeutic strategies for cartilage repair of the talus are varied. With the use of biologic scaffolds and biologic agents new cell-based therapies have become the focus of attention. OBJECTIVES Ankle cartilage repair techniques are presented and assessed by current data. In addition, technical notes for each technique are given. MATERIAL AND METHODS Currently, the following established ankle cartilage repair procedures exist: microfracturing, AMIC (autologous matrix-induced chondrogenesis), OCT (osteochondral transplantation, mosaicplasty), allograft transplantation. DISCUSSION The success of each repair technique is dependent on the proper indication, addressing of co-morbidities like axis deviation or ligament instabilities, the experience of the surgeon and the appropriate rehabilitation. Mid- and long-term results are often good or excellent. Best results are seen in isolated cartilage defects without co-morbidities in patients younger than 40 years of age and non-smokers with normal BMI and early intervention. New cell-based therapies utilize scaffolds and biologic agents. They offer promising perspectives, although current data is inconsistent.

Abstract
Surgical management of rheumatic feet has dramatically changed over the last decades influenced by the development of new pharmacological drugs and tissue-preserving surgical procedures. It has switched from joint resection to joint-sparing procedures as the method of choice. Nevertheless, the surgical interventions commonly used for non-rheumatic patients cannot be applied to rheumatic patients without reflection: in addition to the basic treatment, comorbidities, degree of mobilization of the patient, orthopedic shoe engineering and orthotic treatment play a major role. Due to the decreasing incidence of the classical rheumatic foot, it has become even more important for physicians, physiotherapists and ergotherapists to recognize the development of such a disease as early as possible and immediately start the appropriate treatment.

Abstract
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. METHODS Changes in pelvic tilt inversely change the height of the lesser pelvis and the obturator foramen in AP radiographs. Tilt ratios were calculated by means of these two parameters in simulated radiographs for ten male and ten female pelvises in defined tilt positions. A tilt formula obtained by exponential regression analysis was evaluated by two blinded investigators by means of 14 simulated AP radiographs of the pelvis with pelvic tilts ranging from + 15° to - 15°. RESULTS No differences were found between male and female tilt ratios for each 5° step of simulated pelvic tilt. Pelvic tilt and tilt ratios correlated exponentially. Using the tilt formula, the two blinded investigators were able to assess pelvic tilt with high conformity, a mean relative error of + 0.4° (SD ± 4.6°), and a mean absolute error of 3.9° (SD ± 2.3°). Neutral pelvic tilt is indicated by a tilt ratio of 0.5 when the height of the lesser pelvis is twice the height of the obturator foramen. CONCLUSION The analysis and interpretation of cup position and acetabular parameters may be improved by our method for assessing pelvic tilt in AP radiographs.

Abstract
The wrist and hand form a highly complex organ that is of great importance in almost all daily activities. The hand serves as a tool and an organ of sense. Injuries of the hand and wrist as well as mechanical, neurological or systemic inflammatory changes are common. Taking a detailed history can already lead to a diagnosis. Almost all structures of the hand are easily accessible for clinical examination, i. e. inspection, palpation and clinical tests, including dynamic testing. Diagnostic imaging completes the examination procedure.

Abstract
Few data exist of kinematics of knees with varus and valgus deformities combined with osteoarthritis. The purpose of this study was to reveal different (1) tibiofemoral kinematics, (2) medial and lateral gaps, and (3) condylar liftoff of osteoarthritic knees with either varus or valgus deformity before and after total knee arthroplasty (TKA). For this purpose, 40 patients for TKA were included in this study, 23 knees with varus deformity and 17 knees with valgus deformity. All patients underwent computer navigation, and kinematics was assessed before making any cuts or releases and after implantation. Osteoarthritic knees with valgus deformity showed a significant difference in tibia rotation relative to the femur with flexion before and after TKA, whereas knees with varus deformity did not. Knees with a valgus deformity showed femoral external rotation in extension and femoral internal rotation in flexion, whereas knees with a varus deformity revealed femoral internal rotation in extension and femoral external rotation in flexion. In both groups, gaps increased after TKA. Condylar liftoff was not observed in the varus deformity group after TKA. In the valgus deformity group, condylar liftoff was detected after TKA at knee flexion of 50 degrees and more. This study revealed significant differences in tibiofemoral kinematics between osteoarthritic knees with a varus or valgus deformity before and after TKA. Valgus deformities showed a paradoxic movement pattern. These in vivo intraoperative results need to be confirmed using fluoroscopic or radiographic three-dimensional matching before and after TKA.

Abstract
INTRODUCTION The number of spinal fusion surgeries is steadily increasing and biomechanical consequences are still in debate. The aim of this study is to provide biomechanical insights into the sagittal balance of the spine and to compare spinal load before and after spinal fusion. METHOD The joint reaction forces of 52 patients were analyzed in proximo-distal and antero-posterior direction from the levels T12-L1 to L5-S1 using musculoskeletal simulations. RESULTS In 104 simulations, pre-surgical forces were equal to post-surgical. The levels L4-L5 and T12-L1, however, showed increased spinal forces compression forces with higher sagittal displacement. Improved restauration of sagittal balance was accompanied by lower spinal load. AP shear stress, interestingly decreased with sagittal imbalance. CONCLUSION Imbalanced spines have a risk of increased compression forces at Th12-L1. L4-L5 always has increased spinal loads. These slides can be retrieved under Electronic Supplementary Material.

Abstract
PURPOSE In total knee arthroplasty (TKA), intramedullary guides are often used for aligning the distal femoral cutting block. Because of the highly varying angles between the mechanical axis and the anatomical femoral axis (AMA), different valgus pre-sets have been recommended. The present study investigated the optimal valgus pre-set (measuring the AMA in long-leg radiographs or at 5°, 6°, 7° or 8° valgus) to align the cutting block perpendicularly to the mechanical axis. METHODS The AMA was preoperatively measured in weight-bearing long-leg radiographs. After alignment of the cutting block by means of an intramedullary rod, deviation of the block from the mechanical femoral axis was measured with a pinless navigation device. The true AMA (tAMA) was calculated by adding the valgus pre-set of the alignment rod to the deviation measured with the navigation device. Mean deviations between the tAMA and (a) the AMA measured by the surgeon, (b) the AMA calculated with the computer software, (c) 5°, (d) 6°, (e) 7° and (f) 8° valgus pre-sets were measured for each patient. The lowest mean differences were determined. RESULTS The 40 knees measured showed a mean tAMA of 7.2° valgus (1.7 SD) (range 4°-11.5°). The following mean differences and 95 % limits of agreement were calculated: 2.2 (-1.2, 5.5) to the tAMA for the 5° valgus pre-set, 1.2 (-2.2, 4.5) for 6°, 0.2 (-3.2, 3.5) for 7° and -0.8 (-4.2, 2.5) for 8°. AMA measurements by the surgeon and with the digital medical planning software yielded mean differences of 0.6 (-3.1, 4.3) and 0.4 (-4.1, 4.8), respectively. CONCLUSION In the present setting, the best mean distal femoral cutting block alignment perpendicular to the mechanical femoral axis could be achieved with a valgus pre-set of 7° and not by measuring the AMA. Nevertheless, we recommend conducting weight-bearing radiographs of the entire leg prior to TKA for easy detection of any anatomical varieties, old fractures, long stems of total hip arthroplasties or cement. However, surgeons must be aware that exact coronal component alignment can only be achieved by navigational devices. LEVEL OF EVIDENCE Diagnostic study, Level II.

Abstract
BACKGROUND The number of total knee arthroplasties in elderly patients is increasing in accordance with the demographic shift in the population. OBJECTIVE Analysis of the special situation in the elderly, conservative treatment options, perioperative risk factors, preoperative preparation, special intraoperative features and outcome. METHODS Analysis of currently available scientific data and presentation of own scientific study results. RESULTS Total knee arthroplasty in elderly patients is related to an increased perioperative risk of complications. A thorough interdisciplinary preparation is required to reduce risk factors. Ligament stability of the knee does not correlate with age. The postoperative outcome after total knee arthroplasty in elderly patients is decisively influenced by the preoperative function and psychosocial parameters. CONCLUSION Total knee arthroplasty in elderly patients is particularly challenging for orthopedic surgeons and requires close interdisciplinary cooperation.

Abstract
In cervical and lumbar pain syndromes special injections are key for effective pain therapy. Depending on the origin of pain injections are placed at the nerve root or the joints. Thus, the vicious cycle can be stopped. A correct technical procedure is of enormous importance. Because pharmacological effects and special complications are possible, monitoring and precautions are mandatory.

Abstract
AIM The aim of this review was to evaluate the time-related risk for knee osteoarthritis in patients after ACL injury. MATERIALS AND METHODS The primary search was carried out in different medical databases with the deadline 12.01.2014. The search strategy for the evaluation was [ACL] AND [osteoarthritis] including "all fields". All 1656 title/abstracts were reviewed by two independent researchers who selected 140 papers for full text review. Finally, a total of 21 relevant publications were identified for inclusion in this current paper. RESULTS The incidence of knee osteoarthritis rises significantly over time. Two years after injury it was 6.9%, after 5 years 32.2%, after 7 years 36.3%, and after 10 years 79.6%. At the same time, the crude relative risk of OA rises as the time interval since injury increases. The relative risk of OA has already doubled by 2 years after ACL injury). By 7 years it has increased fivefold and compared with OA status at the time of injury it is still increasing significantly after 10 years. CONCLUSIONS The ACL injury is a significant risk factor for the development of early-onset secondary knee osteoarthritis. Within 5 years of the injury the knee shows clear signs of osteoarthritis on MRI. However, these lesions are often not associated with any clinical signs. Knee osteoarthritis as a severe disease starts 8 years or later after the injury, when it requires treatment.

Abstract
PURPOSE Accurate assessment of cup orientation on postoperative radiographs is essential for evaluating outcome after THA. However, accuracy is impeded by the deviation of the central X-ray beam in relation to the cup and the impossibility of measuring retroversion on standard pelvic radiographs. METHOD In an experimental trial, we built an artificial cup holder enabling the setting of different angles of anatomical anteversion and inclination. Twelve different cup orientations were investigated by three examiners. After comparing the two methods for radiographic measurement of the cup position developed by Lewinnek and Widmer, we showed how to differentiate between anteversion and retroversion in each cup position by using a second plane. To show the effect of the central beam offset on the cup, we X-rayed a defined cup position using a multidirectional central beam offset. According to Murray's definition of anteversion and inclination, we created a novel corrective procedure to balance measurement errors caused by deviation of the central beam. RESULTS Measurement of the 12 different cup positions with the Lewinnek's method yielded a mean deviation of [Formula: see text] (95 % CI 1.3-2.3) from the original cup anteversion. The respective deviation with the Widmer/Liaw's method was [Formula: see text] (95 % CI 2.4-4.0). In each case, retroversion could be differentiated from anteversion with a second radiograph. Because of the multidirectional central beam offset ([Formula: see text] cm) from the acetabular cup in the cup holder ([Formula: see text] anteversion and [Formula: see text] inclination), the mean absolute difference for anteversion was [Formula: see text] (range [Formula: see text] to [Formula: see text] and [Formula: see text] (range [Formula: see text] to [Formula: see text] for inclination. The application of our novel mathematical correction of the central beam offset reduced deviation to a mean difference of [Formula: see text] for anteversion and [Formula: see text] for inclination. CONCLUSION This novel calculation for central beam offset correction enables highly accurate measurement of the cup position.

Abstract
The indices for ulnar translation described by Chamay et al. (1983 , Annales de Chirurgie de la Main, Vol. 2, pp. 5–17), and Bouman et al. (1994 , Journal of Hand Surgery Vol. 19B, pp. 325–329), and for carpal height described by Youm et al. (1978 , Journal of Bone and Joint Surgery, Vol. 40A, pp. 423–431) and Bouman et al. (1994) were compared in pre- and postoperative wrist X-rays of 91 patients with rheumatoid arthritis undergoing radiolunate arthrodesis. Both indices described by Bouman had a higher applicability and sensitivity than the Chamay and Youm indices and are recommended for use with the rheumatoid wrist. However false-negative values may result when the Bouman index for ulnar translation is used to follow up radiolunate arthrodesis.

Abstract
INTRODUCTION Patellofemoral maltracking is a relevant problem after total knee arthroplasty (TKA). Patella navigation is a tool that allows real time monitoring of patella tracking. MATERIAL This video contribution demonstrates the technique of patellofemoral navigation and a possible consequence of intraoperative monitoring. A higher postoperative lateral tilt is addressed with a widening of the lateral retinaculum in a particular manner. CONCLUSION In selected cases of patellofemoral problems, patella navigation is a helpful tool to evaluate patellofemoral tracking intraoperatively. Modifications of implant position and soft tissue measurements can then prevent postoperative patellofemoral maltracking.

Abstract
Lumiracoxib is a cyclooxygenase-2 selective inhibitor in development for the treatment of osteoarthritis (OA), rheumatoid arthritis and acute pain. We reviewed nine clinical studies of 1 − 52 weeks' duration demonstrating the efficacy of lumiracoxib in OA. Male and female patients aged ≥ 18 years with primary OA of the hand, hip or knee received lumiracoxib, placebo or active comparators (diclofenac, celecoxib or rofecoxib). Lumiracoxib provided consistent reductions in OA pain intensity and improvements in the patient's global assessment of disease activity and functional status (assessed using the Western Ontario and McMaster Universities Osteoarthritis Index questionnaire or the Australian/Canadian OA Hand Index). These results were superior to placebo and similar to the active comparators tested. In addition, lumiracoxib was consistently superior to placebo and generally similar to active comparators in terms of the new Outcome Measures in Clinical Trials and Osteoarthritis Research Society International criteria. These were used to provide a single measure of response to treatment, taking into account pain, the patient's global assessment of disease activity and functional status.

Abstract
Background: The correlation between disc prolapse and disc degeneration is important in the evaluation of clinical and occupational disease. The present clinical radiological study investigated whether there is a correlation between disc degeneration (chondrosis) and disc prolapses. Patients and Methods: The present study is a retrospectively trial which was performed with conservatively and surgically treated patients from 2011 till 2013 in our clinic. 100 patients with disc prolapse and chondrosis in current MRI images were recruited. We classified patients into those who exhibited a prolapse and chondrosis in the same segment, those with only disc prolapse and those with only chondrosis. Statistical evaluation for the correlation between chondrosis and disc prolapse was performed with the chi-square test. Odds ratios for prolapse and chondrosis were calculated, as well as interobserver reliability (kappa-value) between the first and second observers of radiological images. Results: In all segments in our 100 patients, 119 radiological findings were made (= 100 %). 54 findings (45 %) with disc prolapse in combination with chondrosis were identified in the same lumbar segment. 43 findings (36 %) exhibited disc prolapse without chondrosis and 22 (19 %) chondrosis without prolapse. In most cases, the findings were seen in the last two segments. There was a statistical correlation between disc prolapse and chondrosis, as seen with the chi-squared test. As regards odds ratios, disc prolapse with chondrosis was 1.25-fold more frequent than prolapse without chondrosis; chondrosis with prolapse was 2.37-fold more frequent than chondrosis without prolapse. The interobserver reliability showed a kappa-value of 0.79 with disc prolapses and a kappa-value of 0.85 with chondrosis. Conclusion: For patients with disc prolapse and chondrosis in the same segment, chondrosis was mostly seen in combination with a prolapse. A causal relation was found between prolapse and chondrosis in the same segment. The interobserver reliability showed high correlation for radiological findings with disc prolapse and very high correlations with chondrosis.

Abstract
A sufficient pain management forms the foundation for a successful operative treatment of orthopedic patients. Clinical guideline standards must be provided to ensure safe and immediate pain therapy. Training in these guidelines should be held for clinical personnel on a regular basis. The visual analog scale (VAS) and the numerical rating scale (NRS) are valid instruments used for assessment of pain intensity. A sufficient pain management includes basic analgesics, analgesics on demand as well as special features, such as regional nerve blocks and patient-controlled anesthesia (PCA). The basic analgesics are primarily the groups of classical non-steroidal anti-inflammatory drugs (NSAID) and cyclooxygenase 2 (COX-2) inhibitors as well as stand by analgesics, such as metamizole. If there is further need for pain therapy, medium strong and strong opioids can be used but adverse events must be taken into consideration.

Abstract
PURPOSE The aim of this prospective study is to validate a vector arithmetic method for measuring acetabular cup orientation after total hip arthroplasty (THA) and to verify the clinical practice. MATERIALS AND METHODS We measured cup anteversion and inclination of 123 patients after cementless primary THA twice by two examiners on AP pelvic radiographs with a vector arithmetic method and compared with a 3D-CT based reconstruction model within the same radiographic coronal plane. RESULTS The mean difference between the radiographic and the 3D-CT measurements was - 1.4° ± 3.9° for inclination and 0.8°± 7.9° for anteversion with excellent correlation for inclination (r = 0.81, p < 0.001) and moderate correlation for anteversion (r = 0.65, p < 0.001). The intraclass correlation coefficient for measurements on radiographs ranged from 0.98 (95 %-CI: 0.98; 0.99) for the first observer to 0.94 (95 %-CI: 0.92; 0.96) for the second observer. The interrater reliability was 0.96 (95 %-CI: 0.93; 0.98) for inclination and 0.93 (95 %-CI: 0.85; 0.96) for anteversion. CONCLUSION The largest errors in measurements were associated with an extraordinary pelvic tilt. In order to get a valuable measurement for measuring cup position after THA on pelvic radiographs by this vector arithmetic method, there is a need for a correct postoperative ap view, with special regards to the pelvic tilt for the future. KEY POINTS • Measuring acetabular cup orientation on anteroposterior radiographs of the hip after THA is a helpful procedure in everyday clinical practice as a first-line imaging modality• CT remains the golden standard to accurately determine acetabular cup position.• Future measuring on radiographs for cup orientation after THA should account for integration of the pelvic tilt in order to maximize the measurement accuracy.

Abstract
The need for operative treatment of severe rheumatic deformities of the hand and wrist is decreasing due to the increased use of disease-modifying drugs; however, some patients do not tolerate or do not sufficiently respond to these drugs, which often results in the hands being affected and in advanced stages to severe deformity and loss of function. In these cases operative surgery can help to slow the progression of rheumatic destruction and restore the function of the patient's hand. This article describes the principles of surgery for rheumatoid arthritis of the hand. A meticulous synovectomy or tenosynovectomy is the first stage of treatment. With progression of rheumatic destruction various salvage procedures are necessary to preserve the best possible functional state.

Abstract
The duration and severity of rheumatic diseases of the shoulder correlate with symptom frequency, structural changes and associated functional limitations. The multifactorial character of the underlying rheumatic disease requires a multimodal therapeutic concept including interaction of surgical and non-surgical disciplines. In addition to basic systemic anti-inflammatory medication, injections targeting the synovial tissue by corticoid instillation and glenohumeral radiosynoviorthesis (with an intact rotator cuff) are further options. Operative interventions on rheumatic shoulders can be characterized as disease-modifying, protective, reconstructive or palliative, depending on the stage. Combining minimally invasive arthroscopic surgical techniques with modern basic therapy has the potential to shift the indications for operative interventions towards an earlier stage of disease without favoring or propagating structural alterations which have already occurred. In cases of severe joint destruction with loss of the rotator cuff, reverse shoulder arthroplasty can be an appropriate option.

Abstract
BACKGROUND Total hip arthroplasty (THA) could be associated with a higher failure rate in patients after osteonecrosis of the femoral head (ONFH) compared to a patient population with primary osteoarthritis prior THA, especially regarding the acetabular component. One major reason could be the compromised acetabular bone quality. Therefore, we performed a retrospective case matched study to assess: 1) Is there a difference in periprosthetic bone mineral density between patients with an ONFH prior THA and controls? 2) Do patients with an ONFH prior THA have a lower bone mineral density compared to controls? 3) Which region in the periprosthetic bone stock is more likely to present differences in periprosthetic bone mineral density between both groups? HYPOTHESIS We hypothesized that there is a poorer bone mineral density (BMD) in the periacetabular bone stock in patients with an ONFH prior THA compared to controls receiving a THA due to primary osteoarthritis. PATIENTS AND METHODS We compared the BMD of 50 patients with ONFH to 50 controls with primary osteoarthritis prior THA using the same implant in mean 5 years after surgery by means of dual energy X-ray absorptiometry (DXA). We analysed 3 acetabular ROIs according to DeLee and Charnley in a modified measurement technique. RESULTS In ROI 3, representing acetabulum's upper aspect, statistically significant lower BMD values for the ONFH group could be found (P < 0.05). No difference was found for the modified ROIs 1 and 2 (respectively medial and lower acetabulum). DISCUSSION The results indicate a poorer periacetabular BMD in patients with ONFH prior THA, which might be responsible for premature loosening of the acetabular cup in THA. Due to a lack of literature, further clinical investigations are required to confirm our results. LEVEL OF EVIDENCE III: retrospective case-control study.

Abstract
Complaints in the region of the hips and pelvis are often difficult to classify. This is due to the fact that pain projection and overlapping can occur; therefore, the complete region of the lumbar spine, pelvis and hips must be considered as a single entity in which alterations can result in radiation throughout the whole region. There are many different anatomical structures within the pelvic region so that the function of various muscle components can be impaired and cause pathological alterations to positional relationships of bony structures or even alterations to other soft tissues, such as ligaments, tendons and labra. In terms of differential diagnostics the groin must be seen as the weak point of the peritoneum and vascular system and taken into consideration. Therefore, a detailed and targeted medical history, functional testing and specific examinations and tests are necessary to narrow down the pathology in question and reach a definitive diagnosis. Orthopedic surgeons must know which conspicuous features can lead to which problems and which anatomical structures are likely to be affected by irritation. The results of the clinical examination are the basis for targeted imaging diagnostics and subsequent therapy.

Abstract
We report the kinematic and early clinical results of a patient- and observer-blinded randomised controlled trial in which CT scans were used to compare potential impingement-free range of movement (ROM) and acetabular component cover between patients treated with either the navigated ‘femur-first’ total hip arthroplasty (THA) method (n = 66; male/female 29/37, mean age 62.5 years; 50 to 74) or conventional THA (n = 69; male/female 35/34, mean age 62.9 years; 50 to 75). The Hip Osteoarthritis Outcome Score, the Harris hip score, the Euro-Qol-5D and the Mancuso THA patient expectations score were assessed at six weeks, six months and one year after surgery. A total of 48 of the patients (84%) in the navigated ‘femur-first’ group and 43 (65%) in the conventional group reached all the desirable potential ROM boundaries without prosthetic impingement for activities of daily living (ADL) in flexion, extension, abduction, adduction and rotation (p = 0.016). Acetabular component cover and surface contact with the host bone were > 87% in both groups. There was a significant difference between the navigated and the conventional groups’ Harris hip scores six weeks after surgery (p = 0.010). There were no significant differences with respect to any clinical outcome at six months and one year of follow-up. The navigated ‘femur-first’ technique improves the potential ROM for ADL without prosthetic impingement, although there was no observed clinical difference between the two treatment groups.

Abstract
Complaints in the region of the hips and pelvis are often difficult to classify. This is due to the fact that pain projection and overlapping can occur; therefore, the complete region of the lumbar spine, pelvis and hips must be considered as a single entity in which alterations can result in radiation throughout the whole region. There are many different anatomical structures within the pelvic region so that the function of various muscle components can be impaired and cause pathological alterations to positional relationships of bony structures or even alterations to other soft tissues, such as ligaments, tendons and labra. In terms of differential diagnostics the groin must be seen as the weak point of the peritoneum and vascular system and taken into consideration. Therefore, a detailed and targeted medical history, functional testing and specific examinations and tests are necessary to narrow down the pathology in question and reach a definitive diagnosis. Orthopedic surgeons must know which conspicuous features can lead to which problems and which anatomical structures are likely to be affected by irritation. The results of the clinical examination are the basis for targeted imaging diagnostics and subsequent therapy.

Abstract
UNLABELLED Aim and Hyopthesis: This systematic review and the metanalysis were performed to investigate the relation between football activity and the potential risk of knee osteoarthritis (possible occupational disease). It was hypothesised that soccer players suffer more than controls from knee osteoarthritis also in cases with an absence of documented major injuries. METHODS The review and the metaanalysis were performed accordingly to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. On 2014.02.01 a search was conducted within the medical databases PubMed, Medline, Cochrane, EMBASE und Web-of-Science. A total of 4,649 papers underwent a "Title-Abstract-Review". Finally 6 publications were included in the metaanaylsis. RESULTS There were no longitudinal community-based studies as well as no Cochrane Reviews regarding the risk of knee osteoarthritis in soccer players. After adjustment of major injuries of the knee, soccer players have a slightly increased risk for knee osteoarthritis: relative risk 1.3 (95 % CI 1.0 - 1.7); I(2) = 37.4 %; p = 0.002. In contrast, in studies without differentiation of injured and non-injured knees, the relative risk was significantly increased: 2.9 (95 % CI 2.0 - 4.1); I(2) = 56.3 %; p < 0.001. CONCLUSIONS Soccer players are a very heterogeneous group. The soccer player's knee undergoes different loadings including minor and major injuries. But the individual load also strongly depends on the player's status, his position within the football field and many other factors. In the absence of a major trauma the soccer player has only a slightly increased risk for the development of osteoarthritis. Thus we conclude that an injury in professional football does not fulfil the characteristics of an occupational disease.

Abstract
Femoral stem version has a major influence on impingement and early post-operative stability after total hip arthroplasty (THA). The main objective of this study was to evaluate the validity of a novel radiological method for measuring stem version. Anteroposterior (AP) radiographs and three-dimensional CT scans were obtained for 115 patients (female/male 63/72, mean age 62.5 years (50 to 75)) who had undergone minimally invasive, cementless THA. Stem version was calculated from the AP hip radiograph by rotation-based change in the projected prosthetic neck–shaft (NSA*) angle using the mathematical formula ST = arcos [tan (NSA*) / tan (135)]. We used two independent observers who repeated the analysis after a six-week interval. Radiological measurements were compared with 3D-CT measurements by an independent, blinded external institute. We found a mean difference of 1.2° (sd 6.2) between radiological and 3D-CT measurements of stem version. The correlation between the mean radiological and 3D-CT stem torsion was r = 0.88 (p < 0.001). The intra- (intraclass correlation coefficient ≥ 0.94) and inter-observer agreement (mean concordance correlation coefficient = 0.87) for the radiological measurements were excellent. We found that femoral tilt was associated with the mean radiological measurement error (r = 0.22, p = 0.02). The projected neck–shaft angle is a reliable method for measuring stem version on AP radiographs of the hip after a THA. However, a highly standardised radiological technique is required for its precise measurement. Cite this article: Bone Joint J 2015; 97-B:306–11.

Abstract
BACKGROUND Surgical site infections are the most common nosocomial infections in orthopedic surgery. Strategies to prevent these infections are of enormous relevance. OBJECTIVES Evidence-based procedures such as hand disinfection, prophylactic antibiotic application, hair removal with electric clippers, or preoperative treatment of Staphyloccus aureus are listed in national and international guidelines. Beside these measures, several scientifically not confirmed methods, e.g., the administration of antibiotic prophylaxis for several days or the usage of helmets during surgery, are still practiced. These measures are not evidence-based and should not be performed anymore. CONCLUSION Only the consequent implementation of evidence-based procedures can help prevent surgical site infections.

Abstract
PURPOSE The present clinical-radiological study examines retrospectively the relation between lumbar disc prolapse and degenerations like chondrosis and spondylosis. METHOD Firstly the relation between disc prolapse and chondrosis was examined. 44 patients with disc prolapse and chondrosis in actual MRI scans in the same segment were recruited in our clinic. By regarding older MRI scans, we could find out which finding was first to occur. Concerning the second question, we followed patients with spondylosis to see if they could progress to a disc prolapse. RESULTS In 67% of our cases with disc prolapse and chondrosis, a chondrosis was seen before the disc prolapse. More than a half had had a spondylosis and a chondrosis in the same segment before the herniation. Only 33% of our cases showed a prolapse before chondrosis. CONCLUSION Concerning patients with disc prolapse and chondrosis in the same segment, chondrosis was seen before the herniation in most cases. Also patients with spondylosis progress to a herniation. A causal relation between both radiological findings is not possible. In a future study it must be analysed with statistical tests whether these results are generally valid.

Abstract
Arthroscopy of the wrist has developed in the shadow of arthroscopy of the large joints. Nowadays, wrist arthroscopy has a relevant importance in the diagnostics and therapy in hand surgery and is indispensable for serious surgery of the wrist. Special equipment and extensive knowledge of the surgeon are necessary for carrying out the procedure.
