the effects of anterior discectomy and interposition al implant upon lumbar motion segment stability
the cadaver spine motion segment behavior under torsional load was evaluated with the disc intact, with partial anterior discectomy and with spacer insertion. the results of this study explain how anterior lumbar discectomy and interbody fusion (alif) affects the torsional stability of the motion segment. the pseudarthrosis rate of the anterior lumbar discectomy and interbody fusion (alif) is k...
BACKGROUND Although closed reduction and percutaneous pinning is accepted as the treatment of choice for displaced supracondylar fracture of the humerus, there are some debates on the pinning techniques, period of immobilization, elbow range of motion (ROM) exercise, and perceptions on the restoration of elbow ROM. This study was to investigate the consensus and different perspectives on the tr...
Inverse Dynamics is used to calculate the forces and moments in joints of multibody systems investigated fields such as Biomechanics or Robotics. In a didactic spirit, this paper begins with an overview derivations kinematical dynamical equations rigid bodies from point view modern Continuum Mechanics. Then, it introduces matrix formulation for solution problems and, finally, reports simple two...
Despite advances in pain management, little formal teaching is given to practitioners and nurses in its use for postoperative orthopedic patients. The goal of our study was to determine the educational needs for orthopedic pain management of our residents, nurses, and physical therapists using a quantitative and qualitative assessment. The needs analysis was conducted in a 10-bed orthopedic uni...
Knowledge of the anatomy and biomechanics of the knee is critical for successful rehabilitation following knee injury and/or surgery. Biomechanics of both the tibiofemoral and patellofemoral joints must be considered. The purpose of this paper is to provide a framework for rehabilitation of the knee by reviewing the biomechanics of the tibiofemoral and patellofemoral joints. This will include d...
Anterior sectional twin bracket appliance (ASTBA) is a sectional mechanism that involves two brackets on upper central incisors. This appliance is previously been used for correction of rotated incisors and midline spacing. But, detail biomechanics for single tooth crossbite correction is not previously explained. Here, in this article, we are presenting a detailed biomechanics of ASTBA for ant...
Orthopedic surgery is a specialty of surgery dedicated to the prevention, diagnosis, and treatment of diseases and injuries of the musculoskeletal system in all age groups. Careers in orthopedic surgery span the spectrum from general orthopedics to those of subspecialty expertise in orthopedic trauma, hand, pediatrics, total joint, foot and ankle, sports medicine, and oncology to name a few.
among the power drills ( electrical/ pneumatic/battery ) used in orthopedic surgery, battery drill has got several advantages. surgeons in low resource settings could not routinely use orthopedic battery drills (obd) due to the prohibitive cost of good drills or poor quality of other drills. “hardware” or engineering battery drill (hbd) is a viable alternative to obd. hbd is easy to procure, ru...
