Randomized Controlled Trial Comparative StudyThree-hour interval drain clamping reduces postoperative bleeding in total knee arthroplasty: a prospective randomized controlled trial.
Total knee arthroplasty (TKA) is a common procedure that has a risk of significant blood loss and blood transfusion, and carries a substantial risk for immunologic reactions and disease transmission. Drain clamping is a popular method that is applied to reduce blood loss after TKA. However, the clamping protocol remains controversial. Therefore, we established a new protocol, 3-h interval clamping, and compared the bleeding control efficacy of this protocol following TKA with the non-clamping technique. ⋯ The 3-h interval clamping is a newly developed protocol for reducing blood loss after TKA. The protocol lessens the decrease in postoperative hemoglobin levels. This protocol can be applied easily without increasing clinical thromboembolic events and wound complications.

Comparative StudyReducing the rate of early primary hip dislocation by combining a change in surgical technique and an increase in femoral head diameter to 36 mm.
We report how changes to our total hip arthroplasty (THA) surgical practise lead to a decrease in early hip dislocation rates. ⋯ We suggest that when primary hip arthroplasty is performed through a posterior approach, a low early dislocation rate can be achieved using the described methods.

The Humerusblock NG: a new concept for stabilization of proximal humeral fractures and its biomechanical evaluation.
The Humerusblock NG represents a new semi-rigid angular stable fixation device for minimally invasive stabilization of proximal humeral fractures. This study evaluates the function and stability of the Humerusblock NG and its biomechanical properties on the basis of two different fracture models under cyclic loading. ⋯ Basic science study.

Case ReportsKlippel-Trenaunay syndrome: a rare cause of disabling pain after a femoral fracture.
Klippel-Trenaunay syndrome (KTS) is characterized by a cutaneous vascular nevus of the involved extremity, as well as bone and soft tissue hypertrophy of the extremity and venous malformations. We present the case of a 52-year-old man with a femoral fracture and a history of haemangiomas, limb bone hypertrophy and varicosity. ⋯ According to our knowledge, this is the second case of KTS managed for femoral fracture. Unlike the previous report in literature, in this case a severe disabling neuropathic pain complicated the clinical management.

Correlation of low back pain caused by lumbar spinal stenosis and depression in women: a clinical study.
Low back pain (LBP) due to spinal stenosis may be one of the most debilitating symptoms to decrease the quality of life. The cause and effect association of LBP and depression is vague. Pain may also be a somatization symptom of depression. This is more frequent in the female population. This clinical study was designed to evaluate the correlation between the level of back pain caused by lumbar spinal stenosis and depression in the female population. ⋯ Our findings indicated a relationship between lumbar spinal stenosis associated pain levels and depression. However, the cause and result relationship still needs to be established yet.
