A Simple Cable Method for Intraoperative Limb Alignment Assessment
نویسندگان
چکیده
Achieving good mechanical axis of the lower extremity is of paramount importance in orthopaedic surgery, not only during joint replacement but also in fracture fixation and deformity correction. However, it is difficult to determine the mechanical axis during surgery. Many techniques have been proposed in clinical practice such as visual inspection, cable method, alignment rods, the axis board , panoramic radiograph images 2 and navigation systems. Among all, cable method is proven to be one of the practical and uncomplicated way yet valid enough to control the mechanical axis intra-operatively .

Leg Length Discrepancy in a Patient with Ipsilateral Total Knee and Total Hip Arthroplasty
Despite concerted intraoperative attempts to establish equal limb alignment, leg length discrepancy (LLD) remains a frequent complication following elective total hip arthroplasty (THA) [1]. A number of effective intraoperative imaging and clinical limb length techniques have been recommended to minimize this complication; however, all of these assessment modalities have their reported limitati...
متن کاملAssessment of lower limb alignment: supine fluoroscopy compared with a standing full-length radiograph.
BACKGROUND While a full-length standing anteroposterior radiograph of the lower extremity provides the best radiographic method for assessing limb alignment, other methods must be used intraoperatively. We have employed intraoperative fluoroscopy with use of an electrocautery cord to assess limb alignment in the supine patient. METHODS We retrospectively compared the measurements of lower lim...

UNLABELLED BACKGROUND The purpose of this study was to assess the concurrent validity of alternative measures of frontal plane knee alignment, namely the radiographic anatomic axis and two clinical measures in patients complaining of knee malalignment as compared with the mechanical axis on full-length radiograph of lower limbs. METHODS The knee-alignment angle was measured in 100 knees of...

Background: The purpose of this study was to investigate the effect of core stability exercises in the trunk area on lower limb alignment and lower and upper limb function in Kyokushin athletes. Methods: The statistical sample of the research consisted of 30 female kyokushin players aged 14-18 years, who were randomly divided into two control and experimental groups. The control group perform...
متن کاملInterval Analysis of Controllable Workspace for Cable Robots
Workspace analysis is one of the most important issues in the robotic parallel manipulator design. However, the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. Controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...
