[A review on psychosomatic factors affecting the outcome after total knee-arthroplasty (TKA)].

Unlabelled: A review on psychosomatic factors affecting the outcome after total knee-arthroplasty (TKA) Objectives: In today's ageing Western societies, arthroplasty is a common treatment for endstage osteoarthritis. Despite highly developed implants and surgery, however, this treatment does not always succeed in relieving pain and restoring joint function, i.e.

Progressive glenoid bone loss caused by erosion in humeral head resurfacing.

Background: Cementless surface replacement of the shoulder represents an alternative to conventional stemmed anatomic prostheses. Glenoid erosion is a well-known complication in hemiarthroplasty. However, there is limited data concerning radiographic evaluation and prognostic factors for this phenomenon.

[The rheumatic cervical spine].

Background: The cervical spine is one of the main sites of manifestation in rheumatoid arthritis outside of the extremities. It can have a decisive influence on disease course via the occurrence of mechanical instabilities as well as neurologic symptoms. Both adequate diagnosis and the corresponding surgical treatment represent a challenge for the involved physicians.

[Indication and limitations of meniscus replacement].

Background: Meniscal lesions are among the most important musculoskeletal disorders and are the most common indication for knee joint arthroplasty. However, the structural integrity and function is rarely retained, and a loss of tissue results. Thus, there is a huge demand for meniscal replacement options.

Bone remodelling around the Metha short stem implant - Clinical and dual-energy x-ray absorptiometry (DXA) results.

Objective: Bony ingrowth of short stems is under investigation.

Method: Over one year bony reactions around the Metha stem were investigated using the DXA method in a standardized zonal system (19 ROIs). Clinical results were documented using the HHS.

[Therapy of Periprosthetic Shoulder Infection].

There are several therapeutic options for the treatment of periprosthetic joint infections of shoulder arthroplasties. In acute infections, the implant can remain in place with open debridement, septic lavage with antibacterial solutions such as octinedine or polyhexanide solution and exchange of all mobile components. In late infections, the therapeutic options after removal of the infected implant are: permanent spacer, resection arthroplasty, one stage revision and two stage revision with or without a temporary spacer.

[Meniscal root lesions: clinical relevance and treatment].

Meniscal roots play an important role in load distribution of the tibiofemoral knee joint. Thus, meniscal root tears are severe injuries of the knee, which significantly expose cartilage to increased stress. Two entities are distinguished: (i) acute root tears that mainly affect the posterolateral root and often occur with ruptures of the anterior cruciate ligament; and (ii) chronic, degenerative root tears that mainly affect the posteromedial root.

[Teaching in orthopaedic and trauma surgery].

The scramble for available places to study medicine in Germany continues. One of the core points within the "Master Plan 2020", which has been recently adopted, is the reform of teaching concepts at German medical faculties. In the future, students of human medicine are to be trained primarily based upon competence-oriented, integrated curricula.

15 years of the histopathological synovitis score, further development and review: A diagnostic score for rheumatology and orthopaedics.

The histopathological synovitis score evaluates the immunological and inflammatory changes of synovitis in a graduated manner generally customary for diagnostic histopathological scores. The score results from semiquantitative evaluation of the width of the synovial surface cell layer, the cell density of the stroma and the density of the inflammatory infiltration into 4 semiquantitative levels (normal 0, mild 1, moderate 2, severe 3). The addition of these values results in a final score of 0-9 out of 9.

[Unloading with insoles, orthotics and braces : Pre-operative leg axis correction or independent treatment?].

Background: Knee osteoarthritis (OA) is a leading joint disease. In most of the early stages it does not involve the whole knee joint. Often, symptoms only or mainly concern the medial compartment combined with a slight varus malalignment.

[Current Status of Spine Surgery in Germany: Results of a Survey of Members of the German Spine Society].

Mono- (MSS) and bisegmental spinal fusion (BSS) are frequently performed surgical interventions in German hospitals. Despite the high number of cases, only few data on treatment procedures and concepts for pre-, peri-, and postoperative care are available. The aim of the survey was to gain detailed insights into treatment procedures and medical approaches in elective MSS and BSS care in Germany in order to extract recommendations for improving patient care.

[Fifteen years of the histopathological synovitis score : Review and further developments of a diagnostic score].

The histopathological synovitis score evaluates in a graded approach, as is largely usual for diagnostic histopathological scores, the immunological and inflammatory changes caused by synovitis. A synovitis score of between 1 and ≤ 4 is classified as low-grade (osteoarthritis-related synovitis, post-traumatic synovitis, meniscopathy-related synovitis and synovitis in hemochromatosis). Synovitis scores of between ≥ 5 and 9 are classified as high-grade synovitis (rheumatoid arthritis, psoriatic arthritis, Lyme's arthritis, post-infection/reactive arthritis and peripheral arthritis in Bechterew disease); sensitivity is 61.

[Skeletal hemangiomas].

Hemangiomas are benign tumors, which are mainly composed of neoplastic blood vessels. The exact pathogenesis is still unclear. They are the most common benign spinal tumors and also occur less commonly in the bones of the extremities.

[Prevention of lateral cortex fractures in open wedge high tibial osteotomies : The anteroposterior drill hole approach].

Background: In osteotomies with larger correction angles, the capacity for elastic deformation is frequently exceeded, resulting in plastic deformation and fracture of the opposite cortex, which may lead to subsequent loss of correction. An anteroposterior drill hole at the apex of the horizontal osteotomy (= hinge) is supposed to increase the capacity of the bony hinge for elastic deformation and ideally to prevent fractures of the opposite cortex.

Materials And Methods: A high tibial osteotomy (HTO) using standard surgical technique was performed in 20 each of Synbones, Sawbones, and human cadaver tibial specimens.

[Hallux valgus : Etiology, diagnosis, and therapeutic principles].

Hallux valgus-the most common forefoot deformity-can cause both pain and decreased mobility. The development and progress of the hallux valgus is a multifactorial process. Different intrinsic and extrinsic causes are responsible.

[Hybrid stabilization technique with spinal fusion and interlaminar device to reduce the length of fusion and to protect symptomatic adjacent segments : Clinical long-term follow-up].

Introduction: Determination of the extent of spinal fusion for lumbar degenerative diseases is often difficult due to minor pathologies in the adjacent segment. Although surgical intervention is required, fusion seems to be an overtreatment. Decompression alone may be not enough as this segment is affected by multiple factors such as destabilization, low grade degeneration and an unfavorable biomechanical transition next to a rigid construct.

[ALIF and PLIF interposition in low-grade isthmic spondylolisthesis L5/S1 : Longterm-Comparison of interbody fusion techniques (ALIF - PLIF)].

Introduction: For the treatment of isthmic spondylolisthesis two alternative interbody fusion techniques are available, the dorsoventral interposition in ALIF technique and the dorsal access interposition in PLIF technique. Due to the complications of anterior lumbar surgery and in order to avoid a second operation, the dorsoventral fusion technique is becoming uncommon and mainly a pure dorsal supply is performed. The aim of the study was to compare the clinical long-term results of both treatment techniques.

[Risk of Hip Dislocation - which Patients Need Special Treatment?].

Introduction: Dislocation of a hip arthroplasty is one of the main complications after primary or revision surgery. Definition of specific risk factors concerning patient, indication and surgery makes it possible to determine risk patients for dislocation.

Aim: The aim of this study is to identify patient-specific risk factors, such as body mass index (BMI), age and gender, in order to evaluate primary dislocation and to correlate with secondary dislocation.

[Management of postoperative wound infections following spine surgery : First results of a multicenter study].

Introduction: The number of spinal surgeries has increased significantly in the last decade, which has led to a correlating increase in the number of problems related to wound healing infection. Current literature has reported a spinal wound infection rate of 0.4 to 20 %.
