Randomized Controlled Trial Comparative Study
Prospective randomized study comparing two cephalomedullary nails for elderly intertrochanteric fractures: Zimmer natural nail versus proximal femoral nail antirotation II.
Although both clinical and biomechanical studies suggest that cephalomedullary implants have a mechanical advantage over extramedullary implants, a high rate of complications or implant failure remains in elderly patients with osteoporosis. In an attempt to address some of these challenges, new implants with improved designs named proximal femoral nail antirotation II (PFNA II) and Zimmer natural nail (ZNN) were developed for elderly patients. Although the PFNA II reportedly has good clinical outcomes, it is unclear which implant achieves better safety and efficacy for treating intertrochanteric hip fractures. The primary objective of this prospective, randomized trial involved 353 patients was to evaluate Harris Hip Score (HHS). The secondary objective was to compare results associated with clinical outcome such as operation time, fluoroscopy time, lateral hip pain, walking ability, and reoperation rate as well as the incidence of cut-out by using implant position and fracture reduction quality. ⋯ Although group I had significant longer operation and fluoroscopy time than group II, both implants are useful tools in the treatment of elderly intertrochanteric fractures as well as only TAD, but not Cleveland zone significantly correlated with lag screw cut-out.

Randomized Controlled Trial Comparative Study
Role of acute negative pressure wound therapy over primarily closed surgical incisions in acetabular fracture ORIF: A prospective randomized trial.
Negative pressure wound therapy use over closed surgical incisions (iNPWT) has proven to be effective at reducing hematoma, wound drainage and infection in high-risk wounds. The purpose of this study was to determine if iNPWT decreased the risk of infection in patients undergoing open reduction internal fixation (ORIF) for acetabular fractures. ⋯ In this randomized prospective trial, iNPWT did not decrease the incidence of deep infections when compared to gauze dressings in patients with acetabular fractures. Although not statistically significant, patients in the iNPWT cohort were 2.77 times more likely to develop a deep infection.

Randomized Controlled Trial Multicenter Study Comparative Study
Posterior versus lateral approach for hemiarthroplasty after femoral neck fracture: Early complications in a prospective cohort of 583 patients.
To compare early complications after the posterior and the direct lateral (transgluteal) approach, when using hemiarthroplasty in the treatment of displaced femoral neck fractures in the elderly. ⋯ There was an 8-fold increased risk for prosthetic dislocations after the posterior approach compared to lateral approach. There was a high risk for recurrent prosthetic dislocations and a subsequent risk for further surgeries and a poor end result. The potential advantages of the posterior approach have not been demonstrated after femoral neck fractures and we advise against its continued use.

Randomized Controlled Trial
Femoral nerve block in a representative sample of elderly people with hip fracture: A randomised controlled trial.
The number of elderly people with hip fracture and dementia is increasing, and many of these patients suffer from pain. Opioids are difficult to adjust and side effects are common, especially with increased age and among patients with dementia. Preoperative femoral nerve block is an alternative pain treatment. ⋯ Patients with hip fracture, including those with dementia, who received femoral nerve block had lower pain scores and required less opioids before surgery compared with those receiving conventional pain management. Femoral nerve block seems to be a feasible pain treatment for elderly people, including those with dementia.
