To compare the radiological and clinical outcomes following three different techniques used in the correction of Scheuermann's kyphosis. Twenty three patients with comparable preoperative radiographic and physical variables (age, gender, height, weight, body mass index) underwent correction of thoracic kyphotic deformity using three different surgical methods. Group A (n=8) had combined anterior and posterior fusion with instrumentation using morselised rib graft. Group B (n=7) had combined anterior and posterior fusion with instrumentation using titanium interbody cages. Group C (n=8) had posterior segmental pedicle screw fixation only. All groups had posterior apical multi-level chevron osteotomy and posterior instrumentation extending from T2 to L2/3. Preoperative and postoperative curve morphometry studied on plain radiographs included Cobb angle, sagittal vertical axis (SVA), sacral inclination (SI) and lumbar lordosis (LL). Preoperative and postoperative questionnaires including ODI, VAS and SRS-22 were also analysed.Objective
Materials and Methods
The thigh is placed over a bolster and the leg is allowed to hang over the end of the table. The hamstring tendons are harvested through the pre-determined 2 centimetres horizontal incision on the posterior medial aspect of the thigh. The hamstring tendons which are individually identifiable at this point are isolated using a tendon hook. The fascial expansions of the tendons, which are easily accessible by this approach, are divided using dissecting scissors. A tendon stripper is then used to free the tendon from its muscular origin proximally and from its insertion at the pes anserinus distally. Only a 5mm stab incision anteromedially is now required to make the tibial tunnel. The rest of the procedure is performed as described by EM Wolfe (
