Comparative StudyEvaluation of peri-operative epidural analgesia with ropivacaine, ropivacaine and sufentanil, and ropivacaine, sufentanil and epinephrine in isoflurane anesthetized dogs undergoing tibial plateau levelling osteotomy.
The purpose of this study was to compare four epidural protocols for peri-operative analgesia in dogs undergoing tibial plateau levelling osteotomy. Forty client-owned dogs were randomly assigned to one of four treatments - groups R0.5 and R1 received 0.5mg/kg and 1mg/kg ropivacaine, respectively. Group SR0.5 received 1 μg/kg sufentanil plus 0.5mg/kg ropivacaine, and group SER0.5 received 1 μg/kg sufentanil, 0.5mg/kg ropivacaine plus 6 μg/kg epinephrine. ⋯ Group SER0.5 showed lower post-operative pain scores, and group R1 significantly greater motor block, compared to the other treatment groups. None of the dogs had urinary retention. Epidural sufentanil-epinephrine-ropivacaine provided superior peri-operative analgesia compared to the other treatments, without producing clinically relevant side effects.

The influence of the femoral force application point on tibial cementing pressure in cemented UKA: an experimental study.
Aseptic loosening is the major cause for implant failure in cemented unicompartmental knee arthroplasty (UKA). Central positioning of the femoral pressure during the tibial cementation process is recommended to achieve equal pressure and a good cementation result. The aim of this study was to verify the central position of the femoral force application point (FFAP) at 45° flexion of the knee and to investigate the influence of ligament tension and cement penetration pressure (CPP) for UKA. ⋯ The central position of the FFAP for the investigated cemented UKA with single radius femoral component at 45° flexion of the knee could be confirmed. A flexion angle of <45° does not influence the position of the FFAP significantly. More than 45° of flexion should be avoided because the FFAP shifts backwards significantly and may cause increased pressures posteriorly and therefore tilting of the component occurs during the cementation process.

Clinical TrialIncidence and radiologic predictor of postoperative patellar instability after Fulkerson procedure of the tibial tuberosity for recurrent patellar dislocation.
Excellent results of anteromedialization of the tibial tuberosity for recurrent patellar dislocation have been reported; however, the contribution of the preoperative anatomic factors to postoperative patellar instability has not been well established. The purpose of this study was to investigate the mid-term results and the incidence of postoperative patellar instability after Fulkerson procedure for recurrent patella dislocation, and to determine the radiologic predictor of the postoperative patellar instability. ⋯ Case-control study, Level III.

The management of acute distal tibio-fibular syndesmotic injuries: results of a nationwide survey.
Ankle fractures are one of the most frequently encountered musculoskeletal injuries, and 10% of patients have a concomitant distal tibiofibular syndesmotic disruption necessitating surgical repair. A national survey was conducted to gain more insight into the current approaches in the management of syndesmotic injuries in the Netherlands. ⋯ Compared with previous surveys our survey is more complete, has the highest response rate and has almost national coverage. Most individual items reviewed compare well with current literature, except for the routine removal of the syndesmotic screw, which might not be encouraged from a literature point of view. For this reason, the results of the current survey will be used in the development of a multicentre randomised controlled trial comparing the functional outcome in routine removal of the syndesmotic screw compared with removal on indication.
