<h3>Importance</h3> The optimal management for acute traumatic cervical spinal cord injury (SCI) is unknown. <h3>Objective</h3> To determine whether early surgical decompression results in better motor recovery than delayed treatment patients with incomplete SCI associated preexisting canal stenosis but without bone injury. <h3>Design, Setting, and Participants</h3> This multicenter randomized clinical trial was conducted 43 tertiary referral centers Japan from December 2011 through November...
A 30-year-old man presented with pain and limitation of movement the right hip. The symptoms had failed to respond conservative treatment. Radiographs CT scans revealed evidence impingement between femoral head-neck junction an abnormally large anterior inferior iliac spine. Resection hypertrophic spine was performed which produced full painless restoration function Hypertrophy as a cause femoro-acetabular has not previously been described.
We retrospectively evaluated 42 hips which had undergone acetabular reconstruction using the Kerboull reinforcement device between September 1994 and December 1998. used autogenous bone chips from ilium ceramic particle morsellised grafts, even in large defects, early stages of study. Thereafter, femoral head allograft was as bulk graft patients with defects. Ceramic blocks patients’ contralateral were also graft. The mean follow-up period 8.7 years (4.3 to 12). Survivorship analysis...
Study Design. Retrospective study. Objective. The aim was to investigate the clinical outcomes in patients with thoracic myelopathy a single institution and identify prognostic factors for poor outcomes. Summary of Background Data. Because rarity myelopathy, few studies have analyzed large number results treated institution. Methods. Seventy-one who underwent surgical treatment between 2000 2011 were included this analysis. We investigated patients' characteristics, outcomes, Results. Of 73...
Although the Neer and AO/OTA classifications have been widely accepted, observer reliability studies of these two questioned their reproducibility to date. We developed an entirely new classification, Mitsuzawa for dislocated displaced proximal humeral fractures tested all three intra- interobserver reliability. Two experienced shoulder surgeons orthopedic residents independently evaluated Xray (xR) values 100 (PHFs). The inclusion criteria PHFs were (1) fracture-dislocation glenohumeral...
Retrospective study. To elucidate the factors influencing identification of causative microorganisms in vertebral osteomyelitis (VO) and effectiveness different culture methods increasing rate. A total 252 patients diagnosed with treated for VO at a single hospital were enrolled. The results various reviewed along clinical data retrospectively. Microbiological diagnosis was achieved 210 out (83.3%). Diagnostic percentages blood cultures, CT-guided drainage, fluoroscopic disc biopsy,...
Abstract Aim Medial meniscus tear has been proposed as a potential etiology of spontaneous osteonecrosis the knee ( SONK ). Disruption collagen fibers within causes meniscal extrusion, which results in alteration load distribution knee. Our purpose was to determine whether extent medial extrusion correlates with severity femoral condyle. Methods Radiological stage and femorotibial angle FTA ) were determined on radiographs. Ellipsoid volume lesion pathology (degeneration, extrusion)...
In Brief Study Design. Case report and clinical discussion. Objective. We a rare case of delayed onset cerebral infarction caused by an embolism after cervical pedicle screw (CPS) fixation. Summary Background Data. CPS has risk vertebral artery (VA) injury. CPSs sometimes breach the transverse foramen without rupture VA. Most breaches are not considered harmful. Methods. present in 71-year-old man who underwent operation for fixation laminoplasty spondylomyelopathy. He presented symptoms...
Retrospective review.To identify risk factors for traumatic cervical spinal cord injury (SCI) associated with ossification of the posterior longitudinal ligament (OPLL) by comparing patients SCI and those myelopathy (CM) OPLL.Although prevalence OPLL among is high, little published about OPLL.We evaluated 3 groups patients: 34 OPLL, 32 CM normal controls. Developmental canal diameter, stenosis, type presence anterior (OALL) were using 3-dimensional computed tomography.The mean age group was...
This study aimed to characterize the process of disease progression in early stage rapidly progressive osteoarthritis hip (RPOH) and clarify its association with potential pathological factors RPOH.This monocentric retrospective included 41 female patients who met criteria for RPOH, chondrolysis >2 mm during 12 months from onset pain based on a series radiographs computed tomography. also 9 secondary developmental dysplasia (DDH) demonstrated pain. Cortical thickness index (CTI) correlated...
Retrospective review.The aim of this study is to assess the radiographic characteristics patients with a retroodontoid pseudotumor and evaluate efficacy posterior fusion.Retroodontoid pseudotumors are usually caused by chronic atlantoaxial instability in rheumatoid arthritis (RA). However, pathomechanism optimum treatment unknown.We reviewed charts radiographs 11 (5 RA 6 non-RA) who underwent fusion. Preoperative were evaluated for atlantodental interval; Redlund-Johnell criterion; O-C1,...
Retrospective review.The aim of this study was to assess the clinical outcomes surgery in patients with simultaneous ossification posterior longitudinal ligament (OPLL) and ligamentum flavum (OLF) at same thoracic spine level identify risk factors for poor outcomes.OPLL complicated OLF is a rare condition. The optimal treatment option myelopathy due OPLL remains controversial, high postoperative paralysis major complication.We conducted retrospective review radiographic records 15 who...
Study Design. A multicenter retrospective analysis Objective. To investigate reoperation of misplaced pedicle screws (MPSs) after posterior spinal fusion (PSF), focusing on neurological complications. Summary Background Data. The management strategy for MPSs and the clinical results are poorly defined. Methods. Subjects were 10,754 patients (73,777 screws) who underwent PSF at 11 hospitals over 15 years. total number reoperations MPS patient data obtained from medical records each hospital....
Abstract Background There has been widespread use of short-segment posterior fixation (SSPF) for traumatic thoracolumbar burst fractures. The relationship between the destruction vertebral endplate and adjacent disc postoperative correction loss studied in only a few studies. This study investigated risk factors following SSPF. Methods Forty-eight patients (mean age 35.0 years) who underwent SSPF fractures were enrolled. mean follow-up period was 25.7 months (12–98 months). neurological...
Case: (1) A 69-year-old man sustained a proximal humeral fracture-dislocation. During emergency surgery, copious bleeding occurred. pseudoaneurysm was identified 30 days postoperatively. (2) fracture and axillary artery injury. Physical examination demonstrated cold but pink hand. Hemiarthroplasty bypass vein grafting were performed. (3) An 86-year-old woman Her hand had turned pale. Reverse shoulder arthroplasty Conclusion: In cases of fractures with significant displacement, concomitant...
Aims This study aimed to evaluate sagittal spinopelvic alignment (SSPA) in the early stage of rapidly destructive coxopathy (RDC) compared with hip osteoarthritis (HOA), and identify risk factors SSPA for destruction femoral head within 12 months after disease onset. Methods enrolled 34 RDC patients joint space narrowing > 2 mm onset pain 25 HOA showing destruction. Sharp angle was measured acetabular coverage evaluation. Femoral collapse ratio calculated assessment extent by RDC. The...
Previous reports have demonstrated that patients with end-stage rapidly progressive osteoarthritis of the hip (RPOH) show significantly higher serum levels bone turnover markers than those (OA). However, characteristics in early stage RPOH remain unclear. This study aimed to elucidate association disease progression RPOH.This included 29 postmenopausal female joint space narrowing >2 mm on a series radiographs and computed tomography within 1 year following onset pain. The also 9 OA...
This study investigated the efficacy and complications of preoperative embolization for spinal metastatic tumors, focusing on etiology post-embolization paralysis.We retrospectively reviewed data 44 consecutive patients with metastases treated between September 2012 December 2020. Intraoperative blood loss postoperative transfusion requirement were compared (+) (-) groups. Complications associated reviewed.Overall, 30 (68%) underwent embolization.
