Background/objectives: This study prospectively evaluated clinical outcomes and osseous consolidation in patients with symptomatic scaphoid non-union treated avascular bone grafting percutaneous screw fixation. Two imaging methods, MDCT (multi-detector computed tomography) HR-pQCT (high-resolution peripheric quantitative computer tomography), were employed to assess healing. Methods: In Vienna, eight consecutive nine non-unions underwent revision surgery. Clinical measured using DASH PRWE...
Background: The management of intra-articular displaced calcaneal fractures remains controversial. Both minimally invasive technique (MIT) and open reduction internal fixation (ORIF) are commonly employed, but there is no clear consensus on the optimal approach. Open surgical techniques carry a higher risk wound complications, whereas percutaneous methods may offer less precise fracture reduction, while conservative therapy (CT) shows functional complications. aim this retrospective study...
Little is known about the effect of sports activity levels on health-related quality life (HRQOL) in long-term survivors lower-extremity sarcoma.Eighty-three bone and soft tissue sarcoma lower extremities with a median follow-up 14 (range: 5-35) years completed University California Los Angeles (UCLA) scores before tumor resection, 1 year after surgery at latest follow-up, as well Short Form 36 (SF-36) health survey follow-up. Simple linear regression models stepwise variable selection...
Modular megaprostheses are known for high infection rates followed by of revisions. Microbial biofilms growing adherently on prosthetic surfaces may inhibit the detection pathogens causing joint infections. We sought to answer following questions: Does sonication culture (SC) improve microbiological diagnosis periprosthetic infections compared conventional tissue (TC)? Which were detected surface with either SC or TC and do findings help identify low-grade infections? Included 31 patients...
Aneurysmal bone cysts (ABC) are benign tumors mostly occurring in children and young adults. Different open minimal invasive surgical approaches have been proposed for the treatment of ABCs yet no consensus is defined to date. The aim this study was retrospectively review data a large single center series with patients treated by curettage or without filling cavity en-bloc resection. Questions/purposes We asked: (1) What local recurrence rate ABC after at our institution? (2) were positive...
Multiple revision hip arthroplasties and critical trauma might cause severe bone loss that requires proximal femoral replacement (PFR). The aim of this retrospective study was to analyse complication- revision-free survivals patients who received modular megaprostheses in an attempt reconstruct massive non-neoplastic defects the femur. Questions/purposes (1) What were general complication rates following PFR? (2) is incidence specific survivals? (3) risk factors leading a diminished PFR...
Purpose: Simple bone cysts are among the most prevalent benign cystic tumor-like lesions in children. Proximal femoral simple may require specific treatment because of increased fracture risk. With limited literature available on this localization, consensus regarding optimal is lacking. We present a large international multicenter retrospective cohort study proximal cysts. Methods: All consecutive pediatric patients with cyst from 10 tertiary referral centers for musculoskeletal oncology...
Introduction Limb salvage surgery for periacetabular malignancies is technically demanding and associated with a considerable likelihood of postoperative complications surgical revision. Reconstruction using custom-made implants represents the treatment choice. This study was conducted to analyze outcomes in single orthopaedic tumor center. Patients Methods Twenty patients histologically verified malignancy median follow up time 5 (1–17) years were included. Results The number revision...
A variety of treatment options for unicameral bone cysts (UBC) exist. The controversy open management UBC is discussed. aim this study was to analyze a single institution's experience in the surgical UBC.
After major lower limb amputation, persistent pain is common, with up to 85% of patients reporting recurring phantom or residual-limb pain. Although management an important factor quality life in amputations, there are few long-term data regarding the frequency and how it impacts prosthesis use.(1) How prevalent different types at follow-up after amputation for malignant tumors? (2) What association do have daily use?Between 1961 1995, 124 amputations tumors were performed one center Austria...
Aneurysmal bone cysts (ABC) are rare benign cystic tumors, generally diagnosed in children and adolescents. Proximal femoral ABCs may require specific treatment strategies because of an increased pathologic fracture risk. As few reports published on ABCs, specifically for this localization, consensus regarding optimal is lacking. We present a large retrospective study the pediatric proximal ABCs.All eligible patients with ABC were included, from 11 tertiary referral centers musculo-skeletal...
Injectable biphasic ceramic bone substitutes (BCBSs) represent a modern alternative to conventional options for defect filling, as they further open the possibilities percutaneous cavity reconstruction. Although recent studies have shown good surgical outcomes after treatment with BCBSs, mid-term follow-up data are still missing. Between 2013 and 2017, 18 patients were [1] treated BCBS [2] benign lesions [3] had complete set of retrospective information, including protocols, imaging, patient...
An in vivo animal model of a weight-bearing intra-articular implant is crucial to the study osseointegration and aseptic loosening caused by failure. Osseointegration, defined as direct structural functional attachment between living bone tissue surface load-carrying implant, essential for stability considered prerequisite long-term clinical success implants total joint arthroplasty. Compared large models, murine models offer extensive genetic tools tracing cell differentiation...
Despite the success of standard antiseptic irrigation solutions in reducing periprosthetic joint infection (PJI) rates, there is still a need for more effective solutions. Synergistic use povidone-iodine (PI) and hydrogen peroxide (H
Background: In comparison to titanium screws, novel cortical bone allograft screws may come with advantages in osseointegration and avoidance of potential material removal surgery after scarf osteotomy. Methods: A osteotomy as fixation was performed 21 patients (30 feet). Clinical radiological parameters were prospectively collected until one year surgery. retrospective control group, consisting 75 (82 feet) using headless compression used compare clinical outcomes. Results: After the mean...
Biomechanical (over-)stimulation, in addition to inflammatory and fibrotic stimuli, severely impacts the anterior cruciate ligament (ACL) biology, contributing overall chronic nature of desmopathy. A major challenge has been lack representative two-dimensional (2D) vitro models mimicking processes presence dynamic mechanical strain, both being crucial for homeostasis. Physiological levels strain exert anti-inflammatory effects, while excessive can facilitate mechanisms. Adhering 3Rs...

This study comprised 175 prospectively included who (1) suffered from fractures, (2) presented during Austrian state emergency period 15 March 2020 30 May...
Zusammenfassung Die Arthrose des oberen Sprunggelenks stellt eine weitverbreitete degenerative Erkrankung der unteren Extremität dar. Obwohl sie in vielen Fällen auf vorhergehende Verletzung zurückgeführt werden kann, können auch chronisch-entzündliche Erkrankungen zu degenerativen Veränderungen führen. Nach umfangreicher Abklärung Patienten zur Indikationsstellung kann die Sprunggelenksprothese im fortgeschrittenen Arthrosestadium als Behandlungsoption für gesehen werden, da prothetische...

Introduction: A previous study of our group in adolescents and young adults with chronic surgical cerebellar lesions has shown that recovery depends on lesion site. If affected the nuclei was worse compared to affecting cortex alone. In a prospective children we were interested if motor impairment is already different acute or not. Severity ataxia stance gait assessed 3 12 months following surgery.
