The Use of Cable-Screw Construct as an Effective Method for Direct Pars Repair
ثبت نشده
چکیده
Spondylolysis is a condition seen in approximately 6-8 % of the population [1]. It involves a defect in the pars interarticularis precipitated by repeated low grade trauma resulting in a stress fracture. The defect is occupied by fibrocartilagenous tissue resulting in non-union [2]. The prevalance is higher among athletes regularly performig hyperextension and rotation activities to the lumbar spine, reaching up to 63% [3].

Repair of pars interarticularis defect with a modified cable-screw construct.
Operative treatment of symptomatic spondylolysis is not common. Multiple surgical techniques have been described for direct repairs of the pars defects. Reported success rates are high, although few reports describe successful return to sports in athletes. The purpose of the study was to assess the outcome after bone grafting and fixation of pars interarticularis defects utilizing a modificatio...
متن کاملA biomechanical comparison of three spondylolysis repair techniques in a calf spine model.
SUMMARY OF BACKGROUND DATA Previous work has demonstrated the efficacy of lumbar pedicle screw hook rod (PSHR) techniques and the Buck screw in the stabilization of spondylolysis. The mechanical behavior of lower profile cervical implants used to create PSHR, hybrid cable plate constructs, and titanium miniplating has not previously been described. METHODS Calf lumbar spines (L2-L6) were util...
متن کاملDirect Pars Repair Surgery Using Two Different Surgical Methods : Pedicle Screw with Universal Hook System and Direct Pars Screw Fixation in Symptomatic Lumbar Spondylosis Patients
OBJECTIVE The authors performed a retrospective study to assess the clinical and radiological outcome in symptomatic lumbar spondylolysis patients who underwent a direct pars repair surgery using two different surgical methods; pedicle screw with universal hook system (PSUH) and direct pars screw fixation (DPSF), and compared the results between two different treated groups. METHODS Forty-sev...
متن کاملThe biomechanical analysis of three plating fixation systems for periprosthetic femoral fracture near the tip of a total hip arthroplasty
BACKGROUND A variety of techniques are available for fixation of femoral shaft fractures following total hip arthroplasty. The optimal surgical repair method still remains a point of controversy in the literature. However, few studies have quantified the performance of such repair constructs. This study biomechanically examined 3 different screw-plate and cable-plate systems for fixation of per...

Cables have always been under consideration as a structural element because of important features such as large strength to weight ratios and long spans. Their equilibrium analysis is an important issue in this regard. But this analysis involves highly nonlinear equations arising from large deformations and material nonlinearity. Different methods have been under use for numerical analysis of s...
