Case Reports[One of the pitfalls in the surgical treatment of maisonneuve fractures: a case report].
There exist controversies in the surgical treatment of maisonneuve injury with regard to reduction and fixation of syndesmosis and management of proximal fibular fracture. It is very important for the orthopaedic surgeons to learn more techniques and avoid pitfalls from clinical practice. We summarized the clinical data of 1 failed case, a 20-year-old girl with big body weight who underwent a primary surgery for the treatment of maisonneuve fracture with minimally invasive reduction and fixation of ankle syndesmosis and posterior malleolus and open reduction and internal fixation of medial malleolus, then a revision surgery for the treatment of iatrogenic syndesmotic malreduction with open reduction and re-stabilization of ankle syndesmosis supplemented with open reduction and internal fixation of proximal fibular facture. ⋯ Attention should be paid to the fact that an obliquely placed clamp for closed reduction of diastasis of ankle syndesmosis could result in syndesmotic malreduction. The worsened alignment of the fracture end of proximal fibula observed by intraoperative fluoroscopy may alert surgeons to syndesmotic malreduction. Partial exposure of syndesmosis and anatomical reduction and fixation of proximal fibular fracture may be useful measurres to avoid malreduction of ankle syndesmosis in the surgical treatment of maisonneuve injury in some patient, especially the patient with critically destabilized ankle.

[Surgical technique and early clinical outcomes of direct anterior approach to total hip arthroplasty].
To describe the surgical technique of direct anterior approach to total hip arthroplasty and to report the early clinical outcomes. ⋯ Direct anterior approach to total hip arthroplasty allows accurate and reproducible cup orientation positioning and leg length restoration and decreases the risk of postoperative dislocation, which is helpful for early rapid postoperative recovery.

[Efficacy of transforaminal endoscopic nerve root decompression in the treatment of degenerative lumbar spinal stenosis].
To evaluate the feasibility of transforaminal endoscopic nerve root decompression for degenerative lumbar spinal stenosis (DLSS). ⋯ We can apply transforaminal endoscopic decompression for the patients of lumbar spinal stenosis who have unilateral nerve root irritation. Patients with transforaminal endoscopic decompression can get less surgical trauma, quick recovery and obtain good short-term outcome.

[Clinical research on robot-assisted percutaneous pelvic and acetabular screws surgery].
To evaluate the security and efficiency of a surgical robotic assisted percutaneous screw fixation for the treatment of pelvic and acetabular fractures. ⋯ Surgical robots are suitable for robot-assisted percutaneous screw fixation in pelvic and acetabular fractures. Robot-assisted treatment of pelvic and acetabular fractures has significant advantages over manual operations including high accuracy, small perspective radiation, safety and efficiency.

[Clinical comparison of polymethylmethacrylate and bone cement in the treatment of osteoporotic vertebral compression fractures: a retrospective study].
To analyze the outcomes of patients with osteoporotic vertebral compression fractures treated with polymethylmethacrylate (PMMA) and GeneX bone cement in percutaneous kyphoplasty and to provide guidance in selecting the vertebral filling material for this procedure. ⋯ GeneX bone cement is similar to PMMA in terms of postoperative pain relief. As the filling material in percutaneous kyphoplasty, it is effective at maintaining vertebral height, quickly improves strength and stiffness of the vertebral body and has fewer complications. However, it is not satisfactory in maintaining long-term postoperative vertebral height. GeneX bone cement can be used as the filling material for patients with osteoporotic vertebral compression fractures in percutaneous kyphoplasty. Patients with severe osteoporosis and vertebral compression should be treated with standardized osteoporosis treatment and should try to avoid early postoperative walking exercises. Sustained vertebral filling materials, such as PMMA, are more suitable for such patients. Research into better biodegradable materials is still needed.
