In patients with recurrent anterior dislocations of the shoulder, it is well known that glenoid rim often deficient (8%-95%). However, little regarding precise location bony defect glenoid.The rather than anteroinferior to glenoid.Cohort study (symptom prevalence); Level evidence, 2.The authors studied 3-dimensional images reconstructed from computed tomography determine in 123 shoulders shoulder. They measured location, extent, and orientation based on clock face defects were located...
Low-intensity pulsed ultrasound is a pain-free therapy performed daily at home by the patient and has been shown to promote fracture healing. Teriparatide parathyroid hormone preparation that activates osteoblastic bone formation also reported be effective in promoting bony union. We report case of 56-year-old Japanese male with femoral shaft who underwent intramedullary osteosynthesis nailing initially. He had no radiologic or clinical sign healing 3 months later low-intensity was initiated...
Purpose. In knee osteoarthritis, the degree of pain varies despite similar imaging findings. If there were quantitative findings related to it could be used for diagnosis or screening. The medial meniscal extrusion was investigated as a candidate finding osteoarthritis. Methods. Seventy-six knees 38 patients (mean age, 73 years) who received intra-articular injections hyaluronic acid into unilateral at time arthritis investigated. Cartilage thickness femoral condyle and bilateral measured by...
High tibial valgus osteotomy (HTO) is a well-established surgical procedure for patients with medial compartment osteoarthritis (OA) of the knee. The hybrid closed-wedge HTO (CWHTO) permits extensive correction in severe deformities or patellofemoral joint OA. aim this study was to report short-term results consecutive series treated CWHTO.We retrospectively evaluated clinical outcomes and radiographic parameters 29 knees that underwent CWTHO correct OA at an average follow-up 52.6 months....
In highly active older individuals, end-stage ankle osteoarthritis has traditionally been treated using tibiotalar arthrodesis, which provides considerable pain relief. However, there is a loss of joint movement and risk future arthrosis in the adjacent joints. Distraction arthroplasty simple method that allows cartilage repair; however, results are currently mixed, with some reports showing improved scores others no improvement. Distal tibial osteotomy (DTO) without fibular type...
Pilon fractures are associated with soft tissue complications such as skin necrosis, and deep infections have been reported very often. This study retrospectively compared the treatment effects of Ilizarov external fixation internal methods in elderly patients pilon fractures. A total 37 >60 years old (AO classification type 43) were investigated. Patients treated either (n = 15) or 22). The patients' mean age was 74.2 (range, 60–78) group 76.1 60–82) group. Many received toe-touch to 1/3...
The purpose of this study was to propose a novel classification varus thrust based on gait analysis with inertial motion sensor units (IMUs) in patients medial knee osteoarthritis (MKOA). We investigated thigh and shank acceleration using nine-axis IMU 69 knees MKOA 24 (control) knees. classified into four phenotypes according the relative medial-lateral vector patterns segments: pattern A (thigh medial, medial), B (medial, lateral), C (lateral, D lateral). Quantitative calculated an...
High tibial valgus osteotomy (HTO) is a well-established surgical procedure to correct varus malalignment and treat medial compartment osteoarthritis. Recently, double level (DLO) was recommended for extensive knees as single (SLO) approach may create an excessive joint line obliquity eventually result in new bony deformity. However, severe knee cases of advanced osteoarthritis involves not only deformity (extra-articular deformity) but also space narrowing with widened lateral...
The purpose of this study was to investigate the relationship between clinical outcomes and lateral thrust before after unicompartmental knee arthroplasty (UKA) using inertial measurement sensor units. Eleven knees were evaluated with gait analysis. varus angular velocity used evaluate thrust. femoro-tibial angle (FTA) hip-knee-ankle (HKA) lower limb alignment, Oxford Knee Score (OKS) Japanese Orthopaedic Association (JOA) outcomes. mean pre-UKA peak 37.1 ± 9.8°/sec, that post-UKA 28.8...
Abstract Background The incidence of periprosthetic fractures after total joint arthroplasty (TJA) is rising due to an increasing number TJAs performed annually and the growing elderly population. In many patients with fractures, bone strength lowered deterioration quality a decrease in quantity; rigid fixation fracture difficult. It challenging operation for orthopedic surgeons. usefulness circular external has been reported several case studies. aim this study was investigate rate union...
Recently, although some studies of open repair the tendon quadriceps femoris have been published, there no reports in literature on primary arthroscopic repair. In our present study, we two cases injury arthroscopically repaired with excellent results. Case 1 involved a 68-year-old man who was injured while shifting his weight to prevent fall. MRI showed complete rupture at insertion patella tendon. The using both suture anchor and pull-out fixation methods via bone tunnels (hereafter,...
The purpose of this study was to clarify the diagnostic accuracy mobile assessment varus thrust using inertial measurement units (IMUs).A total 80 knees in 49 patients were enrolled study. On visual analysis gait determine presence or absence thrust, 23 assigned Present group, 17 Ambiguous and 40 Absent group. peak knee angular velocities (PVVs), measured by quantitative nine-axis IMUs, compared between these three groups. A receiver operating characteristic curve for relationship (Present...
