Electromagnetic Simulation of Non-Invasive Approach for the Diagnosis of Diabetic Foot Ulcers
This study, though a simulation in nature, shows promise for being able to accurately diagnose the peripheral vasculature using electromagnetic parameters. This feasibility study proved successful for possible future implementation using MEMS/NEMS device systems to be designed to detect EM parameters to serve as a diagnostic tool for the early detection of peripheral vascular disease, and ultimately, diabetic foot ulcers.

Bone Preserving Techniques for Explanting the Well-fixed Cemented Acetabular Component
Conclusion Understanding the biomechanical properties of polymethylmethacrylate bone cement and polyethylene can aid in the safe removal of a well-fixed cemented acetabular component in revision hip surgery. The optimal technique for removal of a cemented acetabular component varies depending on a number of patient and implant factors. This summary of the available techniques will be of interest to revision arthroplasty surgeons. (Source: Journal of Orthopaedics)

Correlation of Tibial Bone Defect Shape with Patient Demographics following Total Knee Revision
Conclusion A volumetric classification system of tibial defects is necessary for preoperative planning in revision TKA. Common tibial bone defect shape groups were identified and analyzed in AP and lateral radiographs after revision TKA. Trapezoidal defects were the most common, and all other shapes followed a pattern of proximal enlargement tapering distally. Trapezoidal defects were smaller than other shapes and AP T-bilateral shaped defects were correlated with higher BMIs. (Source: Journal of Orthopaedics)

The Effect of C-Arm Tilt on Accuracy of Intraoperative Fluoroscopy in assessing Acetabular Component Position during Direct Anterior Approach for Hip Arthroplasty
Publication date: Available online 27 March 2018 Source:Journal of Orthopaedics Author(s): Eugene S. Jang, James D. Lin, Roshan P. Shah, Jeffrey A. Geller, H. John Cooper Intraoperative fluoroscopy can improve the precision of acetabular component positioning during direct anterior hip arthroplasty. However, changes in pelvic tilt with c-arm positioning may compromise accuracy. A geometric model of an acetabular component’s projection onto fluoroscopy images was created and manipulated to simulate c-arm tilt.

Factors affecting the return to work of total hip arthroplasty due to of developmental hip dysplasia in in young patients
Conclusions As coxarthrosis associated with DDH develops earlier than primary coxarthrosis, these patients undergo surgery at a younger age and the vast majority are of working age. THA applied for coxarthrosis on the basis of DDH enables most patients to return to their preoperative work and offers the opportunity of finding work to some of those who were unemployed. This increases the contribution of these patients to the national economy. (Source: Journal of Orthopaedics)

Corrective osteotomy in symptomatic clavicular malunion using computer-assisted 3-D planning and patient-specific surgical guides
We describe a corrective osteotomy for a clavicle malunion using 3-D computer assisted preoperative-planning combined with patient-specific surgical guides, along with the benefits and disadvantages of this approach. This method enabled quantifying the malunion by comparing the malunited bone with the normal contralateral clavicle as a template. The postoperative results were encouraging with symmetrical shoulder anatomy and functional improvement. Therefore, we recommend this technique in patients with a symptomatic clavicle malunion, as it allows successful correction of the deformity. (Source: Journal of Orthopaedics)

Total hip arthroplasty via an anterolateral supine approach for obese patients increases the risk of greater trochanteric fracture
Conclusions As the clinical outcome of ALS-THA for the obese group is not inferior to that for the non-obese group, obesity is not considered to be a contraindication for ALS-THA. However, obesity increases the risk of intraoperative greater trochanteric fracture. Thus, surgeons should be particularly careful when manipulating the femur in this class of patients, who should be informed of this risk. (Source: Journal of Orthopaedics)
