BACKGROUND: Quality improvement projects increasingly emphasize standardization of surgical work flow to optimize operative room efficiency. Removing special cause variability resulting from nonsurgical waste is an obvious target; however, resident surgical education must be maintained, even in the setting of process improvement. OBJECTIVE: To describe the impact of resident-identified "risky" or "uncomfortable" procedural steps on operative time during transforaminal lumbar interbody fusion (TLIF)...

BACKGROUND: Patients with knee osteoarthritis (OA) report knee pain, limitation in physical activities and low quality of life. The two primary treatments for knee OA are non-surgical treatment (e.g., exercise) and surgery (total knee arthroplasty (TKA)); however, national guidelines recommend non-surgical treatment to be tried prior to surgical procedures. Patients with knee OA are characterized by decreased muscle strength, particularly in the knee-extensor muscles. Correspondingly, decreased knee-extensor strength is found to be associated with an increased risk of development, progression and severity of knee OA symptoms...

Ultrasound (US) imaging has long been considered as a potential aid in orthopedic surgeries. US technologies are safe, portable and do not use radiations. This would make them a desirable tool for real-time assessment of fractures and to monitor fracture healing. However, image quality of US imaging methods in bone applications is limited by speckle, attenuation, shadow, multiple reflections and other imaging artifacts. While bone surfaces typically appear in US images as somewhat 'brighter' than soft tissue, they are often not easily distinguishable from the surrounding tissue...

Current demographic trends with an increasing number of older patients, have led to a rising number of patients with higher demands on performance. Osteoarthritis in younger patients caused by abnormal forms or accidents also pose new challenges for medical professionals in the orthopedic field. As a rule of thumb, all conservative therapeutic possibilities should be exhausted before starting a surgical intervention. The main aims of surgery are to reduce pain, increase mobility and quality of life. In order to qualify for total knee arthroplasty (TKA) patients must fulfil major and minor criteria; however, after TKA approximately one fifth of patients are not satisfied with the result...

Ronald H M A Bartels, Jan Goffin
Anterior cervical discectomy with fusion (ACDF) is a very well-known and often-performed procedure in the practice of spine surgeons. The earliest descriptions of the technique have always been attributed to Cloward, Smith, and Robinson. However, in the French literature, this procedure was also described by others during the exact same time period (in the 1950s). At a meeting in Paris in 1955, Belgians Albert Dereymaeker and Joseph Cyriel Mulier, a neurosurgeon and an orthopedic surgeon, respectively, described the technique that involved an anterior cervical discectomy and the placement of an iliac crest graft in the intervertebral disc space...

BACKGROUND: Orthopedic trauma injury impacts nearly 2.8 million people each year. Despite surgical improvements and excellent survivorship rates, many patients experience poor quality of life (QOL) outcomes years later. Psychological distress commonly occurs after injury. Distressed patients more frequently experience rehospitalizations, pain medication dependence, and low QOL. This study was developed to test whether an integrative care approach (IntCare; ten-step program of emotional support, education, customized resources, and medical care) was superior to usual care (UsCare)...

BACKGROUND: Although recent trials provided level I evidence for the most common degenerative lumbar spinal disorders, treatment still varies widely. Thus, the Indications in Spinal Surgery (INDIANA) survey explores whether decision-making is influenced by specialty or personal emotional involvement of the treating specialist. METHOD: Nationwide, neurosurgeons and orthopedic surgeons specialized in spine surgery were asked to answer an Internet-based questionnaire with typical clinical patient cases of lumbar disc herniation (DH), lumbar spinal stenosis (SS), and lumbar degenerative spondylolisthesis (SL)...
