This study showed an overall 16.3% radiological PCE and 1.4% symptomatic PCE incidence when CAFPS were used due to severe osteoporosis. The symptomatic PCE risk was significant when CAFPS were > 7 levels; > 14 fenestrated screws; and > 20-25 cc cement volume is used and this may cause PAP increase and right ventricular dilatation.

Full-thickness mesh fixation mechanically supports the fascia, especially in the early postoperative period, and enables homogeneous fibrous healing in a wide area, preventing mesh migration; we believe that these attributes are crucial in reducing the IH recurrence rate.

A ganglion cyst (GC) is a mucinous or gelatinous-filled benign tumor overlying a joint or tendon sheath, which commonly arises in the dorsal and volar wrist side but may occur anywhere in the body. Although cystic lesions around the knee are common, the occurrence of GCs are rare. Ganglia may arise from intra or extra-articular, soft tissue, intraosseous, or periosteal location. Symptoms may vary according to the size and location. After the more frequent performance of magnetic resonance imaging for the assessment of a knee joint, the number of incidental, asymptomatic lesions have been increasingly diagnosed. The etiology of GC remains unclear; however, trauma and a flaw in the joint tissues may explain its appearance. The authors report two cases of women aged 47 years and 37 years who presented pain and swelling in their left knees following arthroscopic partial medial meniscectomy. The former was surgically treated and had a favorable outcome, while the latter had conservative treatment and a gloomy outcome.

Introduction. Paraplegia and kyphotic deformity are two major disease-related problems of spinal tuberculosis, especially in the early age disease. In this study a 2-year-old boy who underwent surgical decompression, correction, and 360° instrumented fusion via simultaneous anterior-posterior technique for Pott's disease was reported. Case Report. A 2-year-and-9-month-old boy presented with severe back pain and paraparesis of one-month duration. Thoracic magnetic resonance imaging demonstrated destruction with a large paraspinal abscess involving T5-T6-T7 levels, compressing the spinal cord. The paraspinal abscess drained and three-level corpectomy was performed at T5-6-7 with transthoracic approach. Anterior instrumentation and fusion was performed with structural 1 autogenous fibula and rib graft using screw-rod system. In prone position pedicle screws were inserted at T4 and T8 levels and rods were placed. Six months after surgery, there was no weakness or paraparesis and no correction loss at the end of follow-up period. Discussion. In cases of vertebral osteomyelitis with severe anterior column destruction in the very early child ages the use of anterior structural grafts and instrumentation in combination with posterior instrumentation is safe and effective in maintenance of the correction achieved and allows efficient stabilization and early mobilization.

Study DesignA single-center, retrospective patient review of clinical and radiological outcomes of microsurgical posterior lumbar interbody fusion and decompression, without posterior instrumentation, for the treatment of lateral recess stenosis.PurposeThis study documented the clinical and radiological results of microsurgical posterior lumbar interbody fusion and decompression of the lateral recess using interbody cages without posterior instrumentation for the treatment of lateral recess stenosis.Overview of LiteratureAlthough microsurgery has some advantages, various complications have been reported following microsurgical decompression, including cage migration, pseudoarthrosis, neurologic deficits, and persistent pain.MethodsA total of 34 patients (13 men, 21 women), with a mean age of 56.65±9.1 years (range, 40-77 years) confirmed spinal stability, and preoperative radiological findings of lateral recess stenosis, were included in the study. Interbody polyetheretherketone cages and auto grafts were used in all patients. Posterior instrumentation was not used because of limited resection of the posterior lumbar structures. Preoperative and postoperative radiographs, computed tomography scans, and magnetic resonance imaging were assessed and compared to images taken at the final follow-up. Functional recovery was also evaluated according to the Macnab criteria at the final follow-up.ResultsThe average follow-up time was 35.05±8.65 months (range, 24-46 months). The clinical results, operative time, intraoperative blood loss, and duration of hospital stay were similar to previously published results; the fusion rate (85.2%) was decreased and the migration rate (5.8%) was increased, compared with prior reports.ConclusionsAlthough microsurgery has some advantages, migration and pseudoarthrosis remain challenges to achieving adequate lumbar interbody fusion.

Objectives: Medial opening-wedge high tibial osteotomy (MOWHTO) is an effective surgical procedure for patients who have medial compartmental osteoarthritis of the knee with varus deformity of the limb. The abnormal load on the medial compartment of the knee relocates to the lateral compartment with this procedure. A gap occurs on the proximal tibia during the correction of varus deformity. Filling this gap with bone grafts or synthetic materials has gained wide acceptance for preventing nonunion or osteotomy site collapse. The aim of this study is to report our results of MOWHTOs performed without any bone graft or any other synthetic materials. Methods: We evaluated 41 MOWHTOs performed between 2009 and 2012 with no use of bone grafts, synthetic materials or spacers. Age of the patients ranged from 43 to 67. Thirty five of the patients were female and 3 of them were male. The follow-up time was 6 months. Results: There were no any non-unions or loss of correction. The mean bone union time was 12,8 weeks. No major complications were seen. Conclusion:The results of our study has shown that achieve satisfactory results can be obtained in MOWHTO without using any bone graft, synthetic materials or spacer.
