Previous designs of internal bone lengthening devices have been fraught with imprecise distraction, resulting in nerve injuries, joint contractures, nonunions, and other complications. Recently, a magnet-operated PRECICE nail (Ellipse Technologies, Inc, Irvine, CA, USA) was approved by the FDA; however, its clinical efficacy is unknown.We evaluated this terms (1) accuracy precision (2) effects on alignment, (3) adjacent-joint ROM, (4) frequency implant-related non-implant-related...
External fixation has evolved from being used primarily as a last resort method to becoming main stream technique treat myriad of bone and soft tissue pathologies. Techniques in limb reconstruction continue advance largely result the use these external devices. A thorough understanding biomechanical principles is useful for all orthopedic surgeons most will have occasionally mount fixator throughout their career. In this review, various types fixators common clinical applications are...
Objectives To evaluate the potential for limb salvage using Ilizarov method to simultaneously treat bone and soft-tissue defects of leg without flap coverage. Design Retrospective study. Setting Level I trauma centers at 4 academic university medical centers. Patients/Participants Twenty-five patients with associated tibial fractures nonunions. The average defect after debridement was 10.1 (range, 2–25) cm 6 2–14) respectively. Patients were not candidates coverage treatment a preamputation...
Objective: To investigate the outcomes of tibial nonunions and bone defects treated with Taylor Spatial Frame (TSF) using Ilizarov method. Design: Retrospective. Setting: Limb Lengthening Deformity Service at an academic medical center. Patients: Thirty-eight consecutive patients 38 were TSF. There 23 (average 5.9 cm) 22 leg-length discrepancy (LLD) 3.1 resulting in average longitudinal deficiency (sum defect LLD) 6.5 cm 31 (1-16). The number previous surgeries was 4 (0-20). At time surgery,...
Distraction osteogenesis has been used for more than 50 years to address limb-length discrepancy and deformity. Intramedullary fixation in conjunction with external decrease the time fixator prevent deformity refracture. A new generation of motorized intramedullary nails is now available treat These provide bone fragment stabilization lengthening reliable remote-controlled mechanisms, obviating need fixation. Motorized allow accurate, well-controlled distraction, early clinical results have positive.
A three-dimensional (3D) knee joint computational model was developed and validated to predict contact forces pressures for different degrees of malalignment. 3D created from high-resolution radiological images emulate passive sagittal rotation (full-extension 65°-flexion) weight acceptance. cadaveric mounted on a six-degree-of-freedom robot subjected matching boundary loading conditions. ligament-tuning process minimised kinematic differences between the robotically loaded cadaver specimen...
Version abnormalities of the femur can cause pain and hip joint damage due to impingement or instability. A retrospective clinical review was conducted on patients undergoing a subtrochanteric derotation osteotomy for either excessive anteversion retroversion femur.A total 55 osteotomies were performed in 43 patients: 36 females 7 males. The average age 29 years (range, 14 59 years). closed with an intramedullary saw. Fixation variety nails. Twenty-nine percent had deformity (average, -9°...
In recent years ankle distraction arthroplasty has gained popularity in the treatment of arthritis as a means both maintaining range motion and avoiding fusion. We present retrospective review 25 patients who have undergone from 1999 to 2006.The mean age was 43 years; 16 were male, 7 female. Followup 30 months after frame removal (range, 12 60 months). able obtain followup on 23 patients. Adjuvant procedures performed some cases including Achilles tendon lengthening (5), arthroscopy (4),...
Patients with limb-length discrepancies often have concomitant deformity. We describe the outcomes of acute, fixator-assisted deformity correction gradual lengthening using retrograde femoral Precice nail (NuVasive).We analyzed a retrospective series 27 patients in whom an external fixator was combined to correct angular or rotational and discrepancy. The applied temporarily restore normal alignment. inserted locked place hold correction, restoration limb length.The (mean age, 28 years) had...
Internal lengthening nail (ILN) is a recent development in limb and deformity correction specialty.The ILN has the distinct advantage of combining acute with gradual bone.While using ILN, short metaphyseal bone fragment may develop at time osteotomy insertion or during because wide medullary canal.These deformities are typically predictable, blocking screws (Poller screws) helpful these situations.This manuscript describes common that occur femur tibia osteotomies different locations while...
Limb salvage in the presence of posttraumatic tibial bone loss can be accomplished using traditional Ilizarov method distraction osteogenesis with circular external fixation. Internal fixation placed at beginning consolidation phase, so-called integrated fixation, may allow for earlier removal fixator but introduces concerns about cross-contamination from additional open procedure and maintenance regenerate stability. Among patients deemed eligible we sought to determine: (1) Does decrease...
The use of bone-anchored osseointegration implants for amputation reconstruction continues to expand throughout the world. Benefits are thought include elimination socket-related problems and improved control proprioception prosthetic limb. Reported outcomes have been positive, but skepticism remains with regard risk infection implant failure. Further results from early adopters therefore needed prior widespread acceptance regulatory approval.A retrospective review first 31 consecutive...

Background: The late sequelae of infantile hip infection include absence the femoral head and neck, proximal migration femur, lower-extremity length discrepancy, abnormal gait, pain. Ilizarov reconstruction includes an acute valgus extension osteotomy at part femur combined with gradual distraction for realignment lengthening a second, more distal, osteotomy. purpose this study was to determine whether technique can successfully treat infection. Methods: We performed retrospective review...
Supramalleolar osteotomy using circular external fixation with six-axis deformity correction is a rarely reported treatment method particularly well-suited for complex multidimensional deformities of the adult ankle. The purpose this study was to assess accuracy and change in functional status technique.We present retrospective review 52 patients who underwent supramalleolar application Taylor Spatial Frame (Smith & Nephew, Memphis, TN). Mean age 44 (range, 18 79) years. primary outcome...
