Filter by:Unplanned re-operation is one of the common negative indicators reflecting the quality and safety of surgery in the medical industry and has become one of the ten goals for the improvement of national medical quality and safety in China since 2022, while about 40% of unplanned re-operations in Peking University Third Hospital in recent years occur in spine patients of the orthopedics department. This project intends to establish a high-quality and sustainable ambispective disease cohort for spine surgery in Peking University Third Hospital based on the unplanned re-operations that occurred in the Orthopedics Department of Peking University Third Hospital from January 2012 to December 2025. The investigators further summarize and analyze clinical causes and risk factors of re-operations, aiming to explore scientific coping strategies and provide reference for continuous improvement of medical service quality.
This is a multicenter, prospective cohort study. The osteoporotic patients requiring posterior lumbar interbody fusion(LIF) with cages are prospectively enrolled and followed up. The patients undergoing LIF with the biomechanical-matched 3D-printed titanium cages (Osteo Match) are compared with those using routine PEEK cages. The hypothesis is that the use of Osteo Match cages can reduce the rate of cage subsidence and increase the rate of lumbar fusion in osteoporotic patients.
The outcome after spinal surgery is important and the evidence is critical to develop treatment. The purpose of this study is to make a prospective registry of database for further research.
This is a prospective single-center study. Patients requiring posterior lumbar interbody fusion (PLIF) for degenerative disease are prospectively enrolled and followed. Patients enrolled in this study have asymptomatic pre-existing spinal canal stenosis at adjacent segment. This study will focus on the effects of preventative limited decompression at adjacent segment.
This is a prospective single-center study. Patients requiring posterior lumbar interbody fusion (PLIF) for lumbar degenerative disease are prospectively enrolled and followed. Important adjacent pre-existing degeneration factors include discs degenerated, facets and ligamentum flavum tropism which could lead to spinal canal stenosis (SCS). This study will focus on the effects of pre- existing adjacent degeneration (disc factors and spinal canal stenosis factors) on long-term postoperative outcomes.
Lumbar spinal decompression and fusion is a commonly performed procedure fro neural impingement and back pain from a variety of pathologies. The importance of pain control in the postoperative period for spinal surgery has been discussed and proven extensively, with both immediate and delayed reduction in complications and improved clinical results. Quadratus lumborum (QL) block was introduced in 2007 and is performed under ultrasound guidance for perioperative pain management in various surgeries.However, the plane for a posterior QL block can be easily reached during open midline spinal surgery. The investigators hypothesize that the posterior QL block is an effective analgesic tool for lumbar laminectomy surgery, because in lumbar laminectomy the quadratus lumborum is already exposed and is in direct visual contact. For that reason it is imperative to test the benefits of this procedure. This is a double blinded randomized control study to assess the results of intra-operative QL block performed for lumbar decompression and fusion.
To prove that the use of additional S2alar-iliac screws for pure lumbar fusions due to degenerative lumbar disease provides superior outcome compared to the standard procedure of fusion to S1.
This is a prospective,observational single-center study. The osteoporotic patients requiring posterior lumbar interbody fusion(PLIF) with cages at the lowest fusion segment are prospectively enrolled and followed up. The patients undergoing PLIF with the 3D-printed porous titanium alloy cages are compared with those using PEEK cages. The hypothesis is that the use of 3D-printed porous titanium alloy cages can reduce the rate of pedicle screw loosening and increase the rate of lumbar fusion in osteoporotic patients.
Lumbar spinal stenosis (LSS) is characterized by low back and leg pain, walking disturbances and sometimes instability, impaired balance and numbness of the lower limbs. This condition is caused by degenerative changes in the lumbar spine including bulging discs, osteophytes from the arthritic facet joints and thickened ligamentum flavum which together cause narrowing of the spinal canal and thus affect the lumbar nerve roots. This diagnosis is attracting more and more interest due to the aging population with increasing demands for physical activity. LSS is the most common indication for spinal surgery. The surgical treatment involves relieving the pressure from the nerve structures in the stenotic segments through a posterior approach. In several studies, surgery has been shown to have better results than the conservative treatment. However, methodological difficulties and a large proportion of cross-over in these studies indicate that there is still uncertainty about whether surgery is generally a better option. It has been speculated whether the compression of the nerve roots causes in some patients permanent nerve damage with muscle denervation, while in other cases a reinnervation and recovery of the function may occur. Results from neurography and EMG studies have been shown these modalities to have a possible predictive value for the natural process of LSS. If a neurophysiological examination could be able to predict which patients are able to benefit from surgery, many patients could avoid surgery and the risks involved in it. The aim of this study is primarily to evaluate whether surgery with decompression leads to superior results than the non-surgical treatment with structured physical therapy. The main secondary aim is to investigate by means of Neurography and EMG, whether the degree of neurological affection caused by nerve compression affects the outcome of surgery for LSS.
