Does addition of gentamicin for antibiotic prophylaxis in total knee arthroplasty reduce the rate of periprosthetic joint infection?
First-generation cephalosporins are used as antibiotic prophylaxis in total joint arthroplasty patients. However, this regimen does not address Gram-negative bacteria causing periprosthetic joint infection (PJI). Previous studies have suggested that the addition of an aminoglycoside as antibiotic prophylaxis in THA reduces surgical site infection (SSI), and less is known on its effect in TKA. This study aimed to investigate if the addition of a single-dose gentamicin, administered pre-operatively, is associated with lower rates of infection in TKA patients. ⋯ A single dose of gentamicin administered pre-operatively to a standard antibiotic prophylaxis was not associated with a statistically significant lower rate of PJI. Although the difference in infection rate did not reach statistical significance, the current study noted a drop in the rate of infection by 1/3 in the gentamicin cohort. Further investigation to evaluate the potential benefit of adding gentamicin to a peri-operative antibiotic regimen is warranted.

Operative room time comparison between general and spinal anesthesia in total hip arthroplasty: an institutional study.
A relatively high expense with any procedure is total operative time; two components being the time spent anesthetizing the patient and time spent transferring the patient out of the operating room (OR). Both times can be affected by the anesthetic method used. This study compares different operative time intervals for both spinal anesthesia (SA) and general anesthesia (GA), in patients undergoing a primary total hip arthroplasty (THA), to identify the most appropriate and cost-effective anesthetic method. ⋯ III.

Influence of kinematics of the lumbopelvic complex in hip arthroplasty dislocation: from assessment to recommendations.
In total hip arthroplasty (THA), misplacement of the implant can provide instability. Adequate orientation of the acetabular cup is a challenge due to variations in inter-individual anatomy and kinematics of the pelvis in everyday life. The aim of this study was to characterize the kinematic factors influencing the risk of dislocation in order to give recommendations for optimal placement of the cup. We hypothesized that the lack of pelvic adaptation would influence the risk of prosthetic instability and motivate adapted. ⋯ Level III (matched case-control study).

Hip abductor tear (HAT) is an increasingly diagnosed cause of refractory lateral hip pain and dysfunction, affecting 10-25% of the general population. ⋯ All patients who underwent an oHATr were able to return at least to one type of sport. This cohort was highly satisfied with their sports involvement and recreational activity achievement. In addition, 88% of patients reported that oHATr improved sports activity. There was a shift from higher to lower impact sports. Furthermore, just 3 hips present a retear after surgery.

Intraoperative 3D imaging in plate osteosynthesis of proximal humerus fractures.
Proximal humerus fractures are common and often associated with osteoporosis in the elderly. Unfortunately, the complication and revision rate for joint-preserving surgical treatment using locking plate osteosynthesis is still high. Problems include insufficient fracture reduction and implant misplacement. Using conventional intraoperative two dimensional (2D) X-ray imaging control in only two planes, a completely error-free assessment is not possible. ⋯ This study shows that insufficient fracture reduction and implant misplacement can be easily and reliably detected by intraoperative DVT scan with an isocentric mobile C-arm set up in the usual parasagittal position to the patient.
