Randomized Controlled Trial
Single tranexamic acid dose to reduce perioperative morbidity in primary total hip replacement: a randomised clinical trial.
Although prophylactic tranexamic acid (TXA) is a safe, low-cost option to reduce bleeding in patients undergoing total hip replacement (THR), its optimal dose and duration is unknown. We compared the safety and effectiveness of TXA given as either a single injection or continuous infusion in THR patients, hypothesising that a second TXA dose would not offer any clinical advantages over the single injection. ⋯ The 30 mg/kg TXA single shot was as safe as continuous infusion. As it is also less cumbersome, we recommend it as part of routine care in THR patients.

Randomized Controlled Trial Comparative Study
Outcome of short proximal femoral nail antirotation and dynamic hip screw for fixation of unstable trochanteric fractures. A randomised prospective comparative trial.
A prospective, randomised, controlled trial was performed to compare the outcome of treatment of unstable trochanteric fractures with either a short proximal femoral nail antirotation (PFNA) or dynamic hip screw (DHS). Eighty one patients with unstable fracture of the proximal part of the femur were randomised, at the time of admission, for fixation with either a short PFNA (n=42) or DHS (n= 39). The primary outcome measure was reoperation within the first postoperative year and mortality at the end of one year. ⋯ Patients treated with a PFNA experienced a shorter fluoroscopy time and less blood loss. Six patients in DHS group had implant failure while none experienced this in PFNA group. The PFNA group had a better functional outcome than the DHS group.

Randomized Controlled Trial
Local anaesthetic wound infiltration after internal fixation of femoral neck fractures: a randomized, double-blind clinical trial in 33 patients.
Pain control may assist early mobilisation after internal fixation of femoral neck fractures. Systemic opioids have significant side effects in elderly patients. We present an evaluation of the effect of local anaesthetic infiltration in such cases , the objective being to decrease the need for postoperative opioids and to improve pain control for patients after surgery. 33 patients undergoing internal fixation with 2 parallel hook pins were randomized into 2 groups in a double blind study (ClinicalTrials.gov: NCT00529425). 33 patients received intraoperative infiltration followed by 6 postoperative injections through an intraarticular catheter in eight-hour intervals. 19 patients received ropivacaine and 14 received saline. ⋯ Apart from a reduction in nausea in the study group on the second postoperative day, there were no significant differences in the occurrence of side effects between the groups. On day 2 the placebo group had less pain than the study group. Local anaesthetic infiltration after fixation of femoral neck fractures does not reduce opioid consumption or pain'.
