Cistanche Deserticola for Regulation of Bone Metabolism: Therapeutic Potential and Molecular Mechanisms on Postmenopausal Osteoporosis.

Osteoporosis is a generalized disease of bone that leads to a loss of bone density and bone mass, destruction of bone microstructure, increased brittleness and therefore fracture. At present, the main treatment of Western medicine is drug therapy such as bisphosphonates, calcitriol, vitamin D, etc. However, long-term use of these drugs may bring some adverse reactions.

Modified Medial Collateral Ligament Indentation Technique in Total Knee Arthroplasty with Severe Type II Valgus Deformity.

Objective: To explore the feasibility and clinical efficacy of a modified medial collateral ligament indentation technique in total knee arthroplasty (TKA) with severe type II valgus deformity.

Methods: Consecutive patients with Krackow type II valgus deformity >20° who underwent a primary unilateral TKA between May 2008 and June 2017 were studied retrospectively. A medial collateral ligament indentation technique was performed in 20 patients (MCLI group), and 23 patients received the routine lateral structures release technique (LSR group).

Additional Dose of Intravenous Tranexamic Acid after Primary Total Knee Arthroplasty Further Reduces Hidden Blood Loss.

Background: Total knee arthroplasty (TKA) is the most frequently performed procedure in treating advanced knee osteoarthritis. Excessive perioperative blood loss can sometimes lead to postoperative anemia. Tranexamic acid (TXA) is a potent fibrinolysis inhibitor which has been extensively used at the surgical incision and closure to lower overall blood loss in adult reconstruction surgery.

Patient-Specific Instruments Based on Knee Joint Computed Tomography and Full-Length Lower Extremity Radiography in Total Knee Replacement.

Background: Restoring good alignment after total knee replacement (TKR) is still a challenge globally, and the clinical efficiency of patient-specific instruments (PSIs) remains controversial. In this study, we aimed to explore the value and significance of three-dimensional printing PSIs based on knee joint computed tomography (CT) and full-length lower extremity radiography in TKR.

Methods: Between June 2013 and October 2014, 31 TKRs were performed using PSIs based on knee joint CT and full-length lower extremity radiography in 31 patients (5 males and 26 females; mean age: 67.

Effect of Femoral Resection on Coronal Overall Alignment after Conventional Total Knee Arthroplasty.

Background: A good postoperative alignment in total knee arthroplasty (TKA) is the key to achieving satisfactory results. We assessed the effect of femoral and tibial resection on the overall alignment after conventional TKA.

Methods: We conducted a retrospective analysis of 212 primary TKAs in 188 patients.

[A case of delayed cervical epidural hematoma with C5 nerve root palsy after posterior cervical laminoplasty].

Delayed postoperative spinal epidural hematoma (DPSEH) is a rare and potentially devastating complication of laminoplasty, and cervical nerve root palsy occurs more frequently than DPSEH, especially with C5 nerve root palsy. The authors describe a case of DPSEH with C5 nerve root palsy that developed in a patient 3 days after he underwent laminoplasty. In this case, a 78-year-old man with a history that having taken Aspirin without the doctor's instruction for 5-6 years, he underwent cervical laminoplasty for mild myelopathy.
