The steroid cohort consisted of 21,995 individuals who had used systemic corticosteroid for a minimum of 6 months between January 1, 1997 and December 31, 2006.

Excess mortality after hip fracture among the elderly in Taiwan: a nationwide population-based cohort study.

Osteoporotic hip fractures cause high mortality in the elderly population. However, few population studies reported the long-term mortality of hip fracture among the elderly in Asian population. This study assessed the incidence, excess mortality, and risk factors after osteoporotic hip fractures through inpatients aged 60 years or older.

Subtalar distraction arthrodesis using fresh-frozen allogeneic femoral head augmented with local autograft.

Background: Tricortical autograft has been commonly used in subtalar distraction arthrodesis (SDA) for severe calcaneal malunion. Structural allograft enriched with orthobiological agents is an alternative. This study was performed to evaluate the results of SDA using fresh-frozen allogeneic femoral head without the addition of orthobiological agents.

Distal linear osteotomy compared to oblique diaphyseal osteotomy in moderate to severe hallux valgus.

Background: There are no comparative studies of proximal and distal osteotomy for treatment of moderate to severe hallux valgus. Our purpose was to compare the surgical outcomes of modified proximal Ludloff (oblique diaphyseal) osteotomy with modified distal Bösch (distal linear) osteotomy by a single surgeon in moderate to severe hallux valgus.

Methods: This retrospective study included feet with a hallux valgus angle greater than 30 degrees.

Analysis of initial injury radiographs of occult femoral neck fractures in elderly patients: a pilot study.

Diagnosis of occult hip fractures by initial radiographs remains challenging in the emergency department. Previously, the gold standard for accurate diagnosis of occult hip fractures was magnetic resonance imaging. This study used initial radiographs obtained in the emergency department to evaluate specific signs and measurements as diagnostic references for occult femoral neck fractures in elderly patients.

Comparison of a minimally invasive technique with open tension band wiring for displaced transverse patellar fractures.

Background: Open reduction and internal fixation with tension band wire is the standard treatment for displaced transverse patellar fractures. Recently, some minimally invasive techniques have been proposed as possible alternative methods. This retrospective study compared a newly reported percutaneous osteosynthesis with conventional open method for the treatment of displaced transverse patellar fractures.

Arthroscopically assisted percutaneous osteosynthesis of displaced transverse patellar fractures with figure-eight wiring through paired cannulated screws.

Introduction: For treatment of displaced transverse patellar fractures, open reduction and internal fixation is the standard reconstructive method. The role of percutaneous osteosynthesis is still unclear and worth of further investigation. Our hypothesis is that satisfactory reduction and rigid fixation is possible for the treatment of displaced transverse patellar fractures with some percutaneous techniques.

Co-overexpression of cyclooxygenase-2 and microsomal prostaglandin E synthase-1 adversely affects the postoperative survival in non-small cell lung cancer.

Introduction: Cyclooxygenase (COX)-2 and microsomal prostaglandin E synthase (mPGES)-1 have been found to be overexpressed in non-small cell lung cancer (NSCLC). The aim of this study was to investigate the expression profiles of COX-2 and mPGES-1 and their correlation with the clinical characteristics and survival outcomes in patients with resected NSCLC.

Methods/results: Seventy-nine paired adjacent normal-tumor matched samples were prospectively procured from patients undergoing surgery for NSCLC.

A noncontact footpad thickness assay to evaluate rheumatoid disease.

Measuring soft tissue thickness is an important step in rheumatoid disease research. The severity of mouse footpad swelling can be used as an indicator of disease progression. A noncontact footpad thickness assay, simplified geometry measurement system (SGMS), was developed that was able to reduce both intra- and interobserver variances during measurements.

Antibiotic-impregnated cement in revision total knee arthroplasty. A prospective cohort study of one hundred and eighty-three knees.

Background: Deep infection following total knee arthroplasty is a devastating complication, and it is very important to prevent it. A prospective cohort study was conducted to evaluate the effect of vancomycin-impregnated cement on the prevention of deep infection after revision total knee arthroplasty performed in a setting in which so-called clean-air measures such as laminar flow and space suits were not available.

Methods: From 1993 to 2004, 183 first-time revision total knee arthroplasties were performed with fixation of all components with cement.

Clinical implications of microsomal prostaglandin e synthase-1 overexpression in human non-small-cell lung cancer.

Background: Microsomal prostaglandin E synthase-1 (mPGES-1) has recently been found to overexpress in human cancers, including non-small-cell lung cancer (NSCLC). However, the clinical value is largely unknown. The aim of this study was to investigate the associations between mPGES-1 expression in NSCLC and the clinical characteristics and survival outcome.

Comparison of the Insall-Salvati ratio of the patella in patients with and without an ACL tear.

The object of this prospective study is to compare the Insall-Salvati ratio between the patients who have an anterior cruciate ligament (ACL) tear and receive arthroscopic-assistant ACL reconstruction and the patients who have no ACL tear but do have an internal disorder of the knee and receive arthroscopic surgery. We prospectively and consecutively collected into two groups a total of 217 patients who had sport injuries and received arthroscopic surgery. The study group included 115 patients who had an ACL tear and received arthroscopic-assistant ACL reconstruction with middle-third bone-patella tendon-bone graft.

Long-term results of pathological stage I non-small cell lung cancer: validation of using the number of totally removed lymph nodes as a staging control.

Objective: The number of totally removed lymph nodes during thoracotomy was used alternatively to represent the quality of lymphadenectomy in patients with pathologic stage I non-small cell lung cancer (NSCLC). We combined this new parameter with other well-established prognostic factors and performed multivariate survival analyses to validate its usage as a stage control.

Methods: Three hundred and twenty-one patients who underwent complete surgical resection for stage I NSCLC were reviewed retrospectively.

Periacetabular osteotomy through a modified ollier transtrochanteric approach for treatment of painful dysplastic hips.

Background: Elimination of abnormally high joint-loading resulting in excessive contact stresses may prevent or reduce the onset of osteoarthrosis in a dysplastic hip. A number of periacetabular osteotomies have been shown to be effective in restoring normal hip-joint mechanics. We treat acetabular dysplasia with a periacetabular osteotomy performed through a modified Ollier transtrochanteric approach.
