Acetabular coverage deficiency displays individual difference among patients with developmental dysplasia of the hip (DDH). Therefore, the correct direction and degree of the acetabular fragment is patient-specific during Bernese periacetabular osteotomy (PAO). This paper introduces a feasible method using 3D computed tomography (CT) and computer image processing technology for customised surgical planning. ⋯ The geometric feature of the pelvis for patients with DDH can be assessed comprehensively by using 3D-CT reconstruction and image processing technology. Based on this method, surgeons can design individualised treatment scheme and improve the effect of PAO.

Randomized Controlled Trial
Peri-articular injections of local anaesthesia can replace patient-controlled analgesia after total knee arthroplasty: a randomised controlled study.
In recent years, there has been an increasing interest in peri-articular injections (PAI) to control post-operative pain after total knee arthroplasty (TKA). Previous studies have evaluated the effect of PAI using multimodal analgaesic protocols, but the concomitant use of patient-controlled analgesia (PCA) may has masked the genuine effects of PAI. We investigated the efficacy of PAI compared with PCA and determined whether conventional PCA can be effectively replaced with PAI after TKA. ⋯ PAI offered improved pain control and minimal side effects compared with PCA. Thus, PAI can replace conventional PCA for controlling post-operative pain after TKA.
