STUDY DESIGN Prospective observational cohort study. OBJECTIVE Comparison of clinical and radiological outcomes of single-level open versus minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) at 6 months and 2-year follow-up. There is recognition that more data are required to ascertain the benefits and risks of MIS vis-a-vis open TLIF.(More)
STUDY DESIGN Retrospective analysis of prospectively collected data. OBJECTIVE To compare midterm clinical and radiological outcomes of minimally invasive surgery (MIS) versus open transforaminal lumbar interbody fusion (TLIF). SUMMARY OF BACKGROUND DATA Open TLIF is a proven technique to achieve fusion in symptomatic spinal deformities and(More)
STUDY DESIGN Prospective cohort study. OBJECTIVE This study aimed to evaluate the learning curve of minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). SUMMARY OF BACKGROUND DATA Very few studies have evaluated the learning curve of this technically demanding surgery. We intend to evaluate the learning curve of MIS TLIF with a larger(More)
BACKGROUND Surgical site infection (SSI) ranges from 1.9% to 5.5% in most large series. Minimally invasive surgery (MIS) has been postulated to reduce SSI rates. QUESTIONS/PURPOSES (1) Is MIS associated with a lower incidence of SSI compared with open spinal surgery? (2) Are there other independent risk factors associated with SSI? (3) What bacteria are(More)
OBJECTIVE To examine health-related quality of life (HRQoL) after total knee replacement (TKR) or unicompartmental knee arthroplasty (UKA). METHODS Asian adult patients undergoing either TKR or UKA in a hospital in Singapore between 2001 and 2006 were interviewed before surgery and 6 and 24 months postoperatively to obtain demographic information and(More)
BACKGROUND CONTEXT Intraoperative reduction of low-grade lumbar spondylolisthesis (LGLS) remains disputed. There is currently no published data comparing midterm outcomes of reduction versus in situ fusion. PURPOSE This study aimed to compare mid-term clinical, radiological, and perioperative outcomes for reduction versus in situ fusion in LGLS with(More)
BACKGROUND Fixation of intra-articular calcaneal fractures has traditionally been guided by intraoperative fluoroscopy. Recent reports indicate that there is a role for subtalar arthroscopy in surgical fixation of these fractures. The earliest reports described the use of subtalar arthroscopy for joint assessment during late hardware removal. It then served(More)
BACKGROUND CONTEXT Multilevel cervical myelopathy can be treated with anterior cervical discectomy and fusion (ACDF) or corpectomy via the anterior approach and laminoplasty via the posterior approach. Till date, there is no proven superior approach. PURPOSE To elucidate any potential advantage of one approach over the other with regard to clinical(More)
OBJECTIVES To compare the responsiveness of the Knee Society (KS) Clinical Rating System, the general health status measure Short Form 36 (SF-36), and both the raw and Rasch-based scores of the condition-specific Oxford Knee Score (OKS) in patients undergoing total knee replacement (TKR) METHODS: Data were prospectively collected as part of routine care(More)
BACKGROUND Percutaneous endoscopic lumbar discectomy is a relatively new technique. Very few studies have reported the clinical outcome of percutaneous endoscopic discectomy in terms of quality of life and return to work. METHOD 55 patients with percutaneous endoscopic lumbar discectomy done from 2002 to 2006 had their clinical outcomes reviewed in terms(More)
