Background: Studies of traumatic knee dislocations have failed to provide a consensus regarding the best method treatment. Purpose: Our purpose was evaluate results after surgical repair or reconstruction versus nonsurgical treatment and compare influence prognostic factors. Study Design: Retrospective study. Methods: Eighty-nine patients were treated for dislocation. Surgical cruciate ligaments performed in 63 (repair, 49; reconstruction, 14). In 26 patients, undertaken. Results: At an...
Etiology and outcome of 155 patients with midfoot fractures between 1972 1997 were analyzed to create a basis for treatment optimization. Cause injuries traffic accidents (72.2%), falls (11.6%), blunt (7.7%) others (5.8%). Isolated (I) found in 55 (35.5%) cases, Lisfranc fracture dislocations (L) 49 (31.2%), Chopart-Lisfranc (CL) 26 (16.8%) Chopart (C) 25 (16%). One hundred forty eight (95%) the treated operatively; 30 closed reduction, 115 open 3 had primary amputation. Seven (5%)...
Intramedullary nailing of metaphyseal fractures may be associated with deformity as a result instability after fixation. Our aim was to evaluate the clinical use Poller screws (blocking screws) supplement stability fixation statically locked intramedullary nails small diameter. We studied, prospectively, 21 tibial fractures, 10 in proximal third and 11 distal 20 patients insertion over mean period 18.5 months (12 29). All had united. Healing evident radiologically at 5.4+/-2.1 (3 12)...
The 3D anatomical complexity of the foot and ankle importance weight-bearing in diagnosis have required combination conventional radiographs medical CT.Conventional plain (XR) demonstrated substantial limitations such as perspective, rotational fan distortion, well poor reproducibility radiographic installations. Conventional CT produces high levels radiation exposure does not offer capabilities.The literature investigating biometrics based on 2D XR has inherent due to technology itself...
Neovascularisation can be detected qualitatively by Power Doppler in Achilles tendinopathy. Quantitative data regarding tendon microcirculation have not been established and may substantial.To assess the of paratendon healthy volunteers as well athletes with either midportion or insertional tendinopathy.Cohort study; Level evidence, 2.In 66 physically active volunteers, parameters microcirculation, such tissue oxygen saturation, relative postcapillary venous filling pressures,...
The aim of the study was to assess feasibility and benefit intraoperative use a mobile C-arm with 3-dimensional imaging (ISO-C-3D).Prospective consecutive clinical study.University hospital, level I trauma center.The ISO-C-3D used for visualization in foot ankle care. Conventional C-arms were judge reduction implant position before used. Time spent, changes resulting from ISO-C-3D, surgeons' ratings (visual analogue scale, 0-10 points) recorded.Between January 1, 2003 March 15, 2004, 62...
Weightbearing CT (WBCT) has been proven to more precisely measure bone position than conventional weightbearing radiographic series (R) and (CT). The purpose of this study was assess the benefit using WBCT instead R and/or as standard imaging modality, evaluating image acquisition time, radiation dose, cost-effectiveness. All patients who obtained a part care from July 1, 2013 until March 15, 2019 were included in study. Image time (T), dose (RD) per patient, cost-effectiveness analyzed...
The purpose of this study was to compare automatic software-based angular measurement (AM) with validated by hand (MBH) regarding angle values and time spent for Weight-Bearing CT (WBCT) generated datasets.
Injury cause, treatment, and long-term results [American Orthopaedic Foot Ankle Society (AOFAS) Midfoot Score, Hannover Scoring System, Outcome Questionnaire] of patients with Chopart joint dislocations or fracture-dislocations were evaluated. Between 1972 1997, 100 110 treated in the authors' institution. Pure observed 28 (25%) feet, 60 (55%) combined Chopart-Lisfranc 22 (20%) feet. The primary treatment was operative 91 (83%) feet nonoperative 19 (17%) Sixty-five (65%) had follow-up after...
In operative calcaneal fracture care malposition of screws and joint line incongruity frequently remain unrecognized using fluoroscopy intraoperatively, are only recognized on postoperative computed tomography scans. The purpose this study was to analyze the feasibility utility a new C-arm-based three-dimensional imaging technology for trauma care.The three- dimensional device (ISO-C-3D) used in 32 patients during 2-year period. Patients were indicated open reduction internal fixation...
Background: Weightbearing cone beam computed tomography (WBCT) has been gaining traction as a useful imaging modality in the diagnosis and follow-up of foot ankle musculoskeletal pathologies due to ability perform quick, low-dose, 3-dimensional (3D) scans. However, resulting wealth 3D data renders daily clinical use time-consuming. The aim this study was evaluate new artificial intelligence (AI)–based automatic measurement for M1-M2 intermetatarsal angle (IMA) hallux valgus (HV). We...
Background In a prospective study, three research groups at Hannover (H) and Munich (M) in Germany Glasgow (G) the United Kingdom collected data from motorcycle crashes between July 1996 1998 to investigate head injury mechanisms helmet-protected motorcyclists. Methods The lesions of motorcyclists with Abbreviated Injury Score-Head (AISHead) 2+ injuries and/or helmet impact were classified into direct force effect (DFE) indirect (IFE) lesions. effecting forces consequences analyzed detail....
Background: We compared different plates in an experimental calcaneal fracture model under biocompatible loading. Methods: Four were tested: a plate without locked screws (Synthes), and three with (Newdeal, Darco, Synthes). Synthetic calcanei (Sawbone) osteotomized to create model, the fixed onto them. Seven specimens for each subjected cyclic loading (preload 20 N, 1,000 cycles 800 0.75 mm/s), load failure (0.75 mm/s). Motion, forces, plastic deformation of plate, consequent depression...
