ObjectiveTo investigate the effect of bridging defects in chronic spinal cord injury using peripheral nerve grafts combined with a chitosan-laminin scaffold and enhancing regeneration through them by co-transplantation bone-marrow-derived mesenchymal stem cells.MethodsIn 14 patients paraplegia caused injury, were grafted cells injected into whole construct contained paste. Patients evaluated International Standards for Classification Spinal Cord Injuries.ResultsChitosan disintegration...
ABSTRACT Purpose: The purpose of the study was to compare results anterior cervical discectomy and fusion (ACDF) using standalone cages versus with plating for multilevel disc disease a 2-year follow-up. Background: ACDF is commonly performed procedure in cases neural compression caused by osteophytes or material. Some spine surgeons have reported unsatisfactory outcomes rates secondary high rate cage subsidence pseudoarthrosis. Internal fixation plate has been developed as an adjunct...
Ununited fractures of the scaphoid with extensive bone resorption are usually treated by grafting and internal fixation, using either an open or a minimally invasive technique. We studied feasibility percutaneous fixation without in consecutive series 27 patients established nonunion undisplaced fracture local bone. They were single surgeon rigid alone, headless cannulated screw inserted through volar Clinical examination, standard radiographs CT confirmed that had united all at mean 11.6...
In Neer type II (Robinson 3B) fractures of the distal clavicle medial fragment is detached from coracoclavicular ligaments and displaced upwards, whereas lateral fragment, which usually small, maintains its position. Several fixation techniques have been suggested to treat this fracture. The aim study was assess outcome patients with treated suture using three loops Ethibond. This prospective included 14 open reduction fixation. Ethibond sutures were passed under coracoid around (UCAC loop)...
Backing out and failure of pedicle screws in patients with osteoporosis is becoming a big problem due to wide use these nowadays.The aim this study evaluate the purchase fenestrated augmented cement osteoporosis.This was retrospective observational study.From May 2015 January 2016, 25 poor bone stock condition underwent posterior fixation by augmentation. Assessment pain improvement done visual analogue score (VAS) while long-term clinical outcome assessed using Oswestry low back disability...
Integrated cage and screw designs were introduced for anterior cervical discectomy fusion (ACDF) allegedly are superior to plating due their minimal profile.A descriptive study was designed as a prospective case series of 25 patients (30 operated discs) with disc disease treated zero-profile cage, followed up an average 16 months (range 12 -18 months). Functional assessment done the Neck Disability Index (NDI) Visual analog scale (VAS) scores arm neck pain. Furthermore, Nurick's...
For the treatment of unstable non-osteoporotic thoracolumbar fractures, clinical and radiological outcome short-segment fixation with USS™ - Universal Spine System (DePuy Orthopedics, Inc., Warsaw, IN, USA) CD HORIZON® LEGACY™ 5.5 Spinal System, (Medtronic Sofamor Danek USA, Memphis, TN, were compared.From March 2015 to January 2016, 40 consecutive patients traumatic fractures who met our inclusion criteria treated either USS system or CDH Legacy system. Segmental kyphosis angle (SKA)...
This was a prospective case series of 30 patients with post-discectomy syndrome an average 18 months follow-up (level IV).The efficacy managed by minimally invasive surgery transforaminal lumbar interbody fusion (MIS-TLIF) evaluated.In wherein conservative treatment had failed, the best surgical modality still remains controversial.Patients were functionally assessed using Visual Analog Scale (VAS) for low back pain (LBP) and leg (LP) Oswestry Disability Index (ODI). Radiological confirmed...
ABSTRACT Background: Low-density screw constructs yield significant radiographic and clinical improvements with reduced risk of neurological complications. This study aimed to investigate the relationship between coronal Cobb angle pelvic incidence (PI) in correction adolescent idiopathic scoliosis (AIS) using a low-density construct, as well association PI functional outcomes. Patients Methods: prospective cohort involved 60 posteriorly instrumented AIS patients, aged 10–16 years, angles...
Study Design: This study was a retrospective observational study.Purpose: The purpose of the to determine radiological and clinical outcome using locally sourced autologous bone graft in surgical management single-level lumbar lytic spondylolisthesis.Background: Many spinal surgeons supplement pedicle screw fixation spondylolisthesis with cages. In developing countries, high cost interbody cages has precluded their use, resorting filling space different types instead. reports on posterior...
Introduction The concept of ‘Ligamentotaxis’ using short segment posterior instrumentation and fusion is widely accepted for managing unstable burst fractures the dorsolumbar spine. aim this work to study possibility performing procedure without fusion. Materials Methods This prospective randomized included 54 patients with spine treated (Group 1); compared a similar group 47 that were by same technique posterolateral iliac crest autograft. Patients followed up an average 5y. Results In...
Background Data: Several controversies exist over the most appropriate approach for managing high grade spondylolisthesis; classic interbody fusions (PLIF) are associated with a considerable degree of complications.Purpose: The aim this work is to determine safety and efficacy unilateral TLIF in isthmic spondylolisthesis.Study Design: Prospective, randomized, between 2000 2008. Patient Sample:44 patients spondylolisthesis (Meyerding grades III IV).The mean age was 24y (range 17-38y). All had...
Background Data: Spondylolysis is a stress fracture of the pars interarticularis that occurs in 2–5% population. Surgical techniques spondylolysis repair have been challenging last decades.
Introduction Scheuermann's kyphosis has long been treated by a two staged fusion and instrumentation with hybrid construct using hooks, pedicle screws sublaminar wires. Interest in all constructs led to its use the treatment of kyphosis. Materials Methods The study included 18 patients who underwent single stage correction segmental screw (Group 1) 17 2). average age was 16y+3m 16y+8m respectively. preoperative dorsal 88 degrees 80 Results Both groups were followed for minimum 2 years....
