Introduction Due to the current COVID-19 pandemic, the German Health Ministry has issued restrictions applying to the field of orthopaedics and trauma surgery. Besides postponement of elective surgeries, outpatient consultations have been drastically reduced. Parallel to these developments, an increase in telemedical consultations has reflected efforts to provide sufficient patient care. This study aims to evaluate the feasibility of a clinical examination of the hip joint and pelvis by way of a telemedical consultation. Materials and Methods Twenty-nine patients of a German university clinic were recruited and assessed in both telemedical and conventional examinations. Agreement between the two examinations was then assessed, and connections between the observed agreement and patient-specific factors such as age, BMI and ASA classification were investigated. Results The inspections agreed closely with a mean Cohenʼs kappa of 0.76 ± 0.37. Palpation showed adequate agreement with a mean Cohenʼs kappa of 0.38 ± 0.19. Function showed good agreement with a mean Cohenʼs kappa of 0.61 ± 0.26 and range of motion showed adequate agreement with a mean Cohenʼs kappa of 0.36 ± 0.19. A significant positive correlation was observed between the number of deviations in the different examinations and age (p = 0.05), and a significant positive correlation was shown between the number of non-feasible examinations and age (p < 0.01), BMI (p < 0.01) and ASA classification score (p < 0.01). Discussion Inspection and function can be reliably evaluated, whereas the significance of palpation, provocation and measurement of range of motion is limited. The small sample size puts limitations on the significance of a statistically relevant correlation between patient-specific factors such as age, BMI and ASA classification score and valid and successful implementation of a telemedical examination. The authors recommend targeted patient selection. If, however, patients are being evaluated who are very old (> 75 years), obese (BMI > 30) or with multiple comorbidities (ASA 3 and above), caution is advised. Large, prospective studies are needed in the future to fully validate telemedical consultations in the fields of orthopaedics and trauma surgery. Conclusion A telemedical examination of the hip joint and pelvis can be performed with certain limitations. Patient-specific factors such as age, BMI, and extent of comorbidities appear to have a relevant impact on validity and execution of the examination. Patients with multiple comorbidities (ASA 3 and above), advanced age (> 75 years) or obesity (BMI > 30) should, whenever possible, be examined in a conventional outpatient setting.
The facial nerve is responsible for any facial expression channeling human emotions. Facial paralysis causes asymmetry, lagophthalmus, oral incontinence, and social limitations. Facial dynamics may be re-established with cross-face-nervegrafts (CFNG). Our aim was to reappraise the zygomaticobuccal branch system relevant for facial reanimation surgery with respect to anastomoses and crossings. Dissection was performed on 106 facial halves of 53 fresh frozen cadavers. Study endpoints were quantity and relative thickness of branches, correlation to "Zuker's point", interconnection patterns and crossings. Level I and level II branches were classified as relevant for CFNG. Anastomoses and fusion patterns were assessed in both levels. The zygomatic branch showed 2.98 AE 0.86 (range 2-5) twigs at level II and the buccal branch 3.45 AE 0.96 (range 2-5), respectively. In the zygomatic system a single dominant branch was present in 50%, two co-dominant branches in 9% and three in 1%. In 66% of cases a single dominant buccal twig, two co-dominant in 12.6%, and three in 1% of cases were detected. The most inferior zygomatic branch was the most dominant branch (P = 0.003). Using Zuker's point, a facial nerve branch was found within 5 mm in all facial halves. Fusions were detected in 80% of specimens. Two different types of fusion patterns could be identified. Undercrossing of branches was found in 24% at levels I and II. Our study describes facial nerve branch systems relevant for facial reanimation surgery in a three-dimensional relationship of branches to each other. Clin. Anat. 32:480-488, 2019.
Multiple myeloma is a haematological blood cancer of the bone marrow and is classified by the World Health Organisation (WHO) as a plasma cell neoplasm. In multiple myeloma, normal plasma cells transform into malignant myeloma cells and produce large quantities of an abnormal immunoglobulin called monoclonal protein or M protein. This ultimately causes multiple myeloma symptoms such as bone damage or kidney problems. The annual worldwide incidence of multiple myeloma is estimated to be 6 - 7/100,000 and accounts for 1% of all cancer. In Germany, there are about 6,000 cases of newly diagnosed multiple myeloma per annum. In the current era of new agents, such as immunomodulatory drugs and proteasome inhibitors and antibodies, enormous progress has been achieved in the therapy of multiple myeloma. In orthopaedics, it is essential to be able to recognise the of alarming symptoms of multiple myeloma in clinical routine and to be aware of basic diagnostic features to confirm this disease. Surgical treatment of myeloma-related bone lesions - such as stabilisation of pathological fractures - is an important domain of tumour orthopaedic surgery. A comprehensive literature search was performed in PubMed using the keywords "multiple myeloma" and "diagnostic" or "therapy". This served to evaluate the available primary and secondary literature on the current status of the diagnostic testing and therapy of multiple myeloma. Systematic reviews, meta-analyses and clinical studies as well as international recommendations in therapy were included until the spring of 2016. There are now very sensitive screening methods for the diagnosis of multiple myeloma. Accurate diagnosis is generally based on several factors, including physical evaluation, patient history, symptoms, and diagnostic testing results. The standards for initial diagnostic tests are determined by blood and urine tests as well as a bone marrow biopsy and skeletal imaging, such as X-rays, CT scans and MRI scans. Major and minor criteria are required to confirm the diagnosis of multiple myeloma and help to determine the classification and staging of multiple myeloma, and whether it is smoldering myeloma (asymptomatic), symptomatic myeloma, or a monoclonal gammopathy of undetermined significance (MGUS). Multiple myeloma treatment options have increased significantly over the last 10 years. Standard of basic myeloma treatment consists of high dose chemotherapy in combination with autologous stem cell transplantation. Several factors may determine multiple myeloma treatment, such as age and general health, results of laboratory and cytogenetic (genomic) tests as well as symptoms and disease complications. After evaluation of these factors, an individual and often multimodal treatment plan is created and implemented in interdisciplinary cooperation. Conventional treatment options have to be evaluated for older patients (> 70 - 75 years), who are not eligible for high dose chemotherapy and autologous stem cell transplantation due to their age and/or severe comorbidities.

Background: Ankle arthropathy is a frequent complication of haemophilia, reducing the patients' quality of life. Despite intensive conservative therapy, end-stage arthropathy requires surgical treatment, either by ankle fusion (AF) or total ankle replacement (TAR). Methods: Eleven consecutive AFs were performed in nine patients and 11 TARs were implemented in 10 patients. Outcomes were assessed clinically by AOFAS score and radiologically by the Pettersson and Gilbert scores. Results:The mean age of the patients in these groups were 35.7 years and 49.4 years, respectively. Of the 11 ankles that underwent fusion, 10 showed bony consolidation not later than 12 weeks after surgery, whereas one still showed non-union after 6 months. VAS pain scores decreased significantly in both groups. Mean AOFAS scores also improved significantly, from 28.1 before to 80.3 after AF and from 21.5 before to 68.0 after ankle replacement. No perioperative complications were observed in either group. Late deep infection was observed in two patients that underwent TAR, which required removal of the implant. Conclusion:Our data indicate that both AF and TAR result in significantly reduced pain in patients with haemophilia with end-stage haemophilic arthropathy. While TAR is associated with a higher risk of deep infection and minimal persistent pain, it preserves the pre-operative range of motion. AF on the other hand is associated with the risk of non-union and a longer post-operative recovery period but results in greater pain reduction.
In therapy of multiple myeloma, surgical treatment is often required in order to reduce distress and retain the function and flexibility of myeloma affected bone sections and the mobility and quality of life of the cancer patient. The range of surgical strategies is complex and demanding.
