STUDY DESIGN In vitro and in vivo studies to assess the effect of direct anular repair on subsequent degeneration of intervertebral discs (IVDs). OBJECTIVE To assess whether a new suturing method could provide sealing effect on IVD after discectomy, and influence degenerative process of IVD. SUMMARY OF BACKGROUND DATA Recurrent disc herniation and(More)
We report a young man with gouty discitis of the cervical spine. To our knowledge, our patient is the youngest patient with cervical gouty discitis reported in the literature. The clinical manifestation was similar to that of cervical spondylosis with radiculopathy. Gouty discitis was diagnosed only when tophi in the disc were found during surgery and(More)
BACKGROUND Over the last few years, new treatments for a damaged intervertebral disc (IVD) have included strategies to repair, replace, or regenerate the degenerative disc. However, these techniques are likely to have limited success, due to insufficiently effective means to address the damaged anulus fibrosus (AF). Here, we try to develop a bioprocess(More)
STUDY DESIGN Retrospective review of an anterior polyetheretherketone (PEEK) cage incorporated with a bovine xenograft to treat disorders of the cervical disc. OBJECTIVE To assess the achievement of fusion by PEEK cage with xenograft radiographically and clinically when used to perform ACDF. SUMMARY OF BACKGROUND DATA Anterior cervical discectomy and(More)
Soy protein, a rich source of phytoestrogens, exhibit estrogen-type bioactivity. The purpose of this study was to determine if ingestion of isoflavones before ovariectomy can prevent bone loss following ovariectomy. Twenty-four nulliparous Wistar rats were randomly divided into four groups. In the normal diet groups, a sham operation was performed on Group(More)
BACKGROUND The treatment of adhesive capsulitis is a dilemma for orthopaedic rehabilitation specialists. In this study, we assessed whether extracorporeal shockwave therapy (ESWT) improves the functional outcome of primary shoulder adhesive capsulitis. METHODS In this prospective, randomized, controlled, single-blind clinical trial, we enrolled 40(More)
BACKGROUND The adverse effects of annulotomy during lumbar discectomy have been increasingly recognized, and methods are developing to repair the annular defect. Biomechanically, the repair should retain the intra-nuclear pressure, which is doubtful using the current suture techniques. Therefore, a new suture technique was designed and tested to close a(More)
Di-isononyl phthalate (DINP) is a general-purpose plasticizer for polyvinyl chloride. However, this industrial chemical plasticizer used as a clouding agent has recently contaminated food and beverages that had been inspected by Taiwan Food and Drug Administration. This study develops a sensitive and specific method combining ultra-performance liquid(More)
Recent advances in tissue engineering have led to potential new strategies, especially decellularization protocols from natural tissues, for the repair, replacement, and regeneration of intervertebral discs. This study aimed to validate our previously reported method for the decellularization of annulus fibrosus (AF) tissue and to quantify potentially(More)
BACKGROUND CONTEXT Minimally invasive spine surgery has become increasingly popular in clinical practice, and it offers patients the potential benefits of reduced blood loss, wound pain, and infection risk, and it also diminishes the loss of working time and length of hospital stay. However, surgeons require more intraoperative fluoroscopy and ionizing(More)
