Randomized Controlled TrialA randomized controlled trial of minor hand surgeries comparing wide awake local anesthesia no tourniquet and local anesthesia with tourniquet.
Epinephrine and sodium bicarbonate (NaHCO3) used in wide-awake local anesthesia no tourniquet (WALANT) affect many areas such as hemostasis, injection pain, anesthetic effect and others. However, few clinical trials have focused on injection pain and the duration of anesthetic effect, and no prospective studies have reported the benefits of WALANT post operation. This study compared WALANT with conventional local anesthesia with tourniquet in minor hand surgeries, and aimed to answer following questions: (1) Does WALANT have enough benefits for injection pain and duration of anesthetic effect?; (2) How does WALANT affect postoperative management (such as postoperative pain and use of analgesics)?; (3) How satisfied are the patients with the surgery? ⋯ II.

Randomized Controlled TrialMid-term gender-specific differences in periprosthetic bone remodelling after implantation of a curved bone-preserving hip stem.
The implant-specific periprosthetic bone remodelling in the proximal femur is considered to be an important factor influencing the long-term survival of cementless hip stems. Particularly data of gender-specific differences regarding bone-preserving stems are very rare in literature and mainly limited to short-term investigations. Therefore, we investigated at mid-term one arm of a prospective randomised study to evaluate if there is an influence of gender on implant-specific stress shielding after implantation of a curved bone preserving hip stem (Fitmore) 5 years postoperatively. ⋯ Proximal stress shielding was observed independent of gender 5 years postoperatively. However, there was a significantly lower bone loss proximal lateral and medial below the calcar in male patients, indicating a more physiological load transfer.
