Objectives: To quantify the occupational radiation exposure with a 3-dimensional (3D) fluoroscopic machine during routine use in pelvic and acetabular surgery and to determine whether the additional radiation exposure encountered with the 3D fluoroscopic spin is within previously accepted limits.
Design: Prospective cohort study.
Setting: Level I trauma center.
Article Synopsis
- Epinephrine in arthroscopic irrigation improves surgeon-rated visual clarity in shoulder surgeries, and subacromial injections are also explored for their effects.
- A study aimed to determine if preoperative subacromial injections of epinephrine enhance surgeon visualization during arthroscopic shoulder surgery, hypothesizing that it would lead to better outcomes.
- In a randomized controlled trial with 60 patients, while the epinephrine group reported slightly better visual clarity scores, the difference was not statistically significant, indicating no clear advantage over the control group.
Background: Previous studies comparing reoperation risk between integrated dual lag screw (IDL) and single lag component (SL) cephalomedullary nails (CMNs) in the treatment of intertrochanteric femoral fractures have demonstrated mixed results. The purpose of this study was to assess the rates of reoperation for fixation failure and all-cause reoperation in a large, multi-institutional cohort of patients with an intertrochanteric fracture treated with an IDL or SL CMN. We hypothesized that there would be no difference between the groups with respect to either of the reoperation rates.

Design: Retrospective review.
Setting: Eight academic level I trauma centers.
Background: Many surgical techniques have been described for acromioclavicular (AC) joint reconstruction. Creation of bone tunnels through the clavicle or coracoid has been shown to be a risk factor for fracture. Use of an AC reconstruction technique that does not create bone tunnels may obviate this risk.

- This study compares two treatment methods for tibia fracture-related infections (FRIs) within 90 days of initial intramedullary nail (IMN) placement: debridement, antibiotics, and implant retention (DAIR) versus IMN removal with further fracture stabilization strategies.
- Out of 66 patients treated, approximately 42.4% received DAIR and 57.6% had IMN removal, with both methods showing similar rates of bone healing (75.8% achieved healing).
- Factors like time from injury, fracture severity, and fewer surgeries after treatment were linked to better healing outcomes, but neither treatment method significantly outperformed the other in preventing persistent nonunion or amputation.
Benzodiazepine withdrawal is a widespread problem with potentially severe and deadly consequences. Currently, the only medications available for treating benzodiazepine withdrawal are short-acting and long-acting benzodiazepines. Identifying other drugs to help in treating benzodiazepine withdrawal is necessary.

Here we investigate the changes in stability and structure resulting from the phosphorylation of collagen. Additionally, the formation of pairwise interactions between phosphorylated residues and lysine is examined.
