Orientated-quantitative computed tomography study on individualized axial safety target area of femoral neck screw channel and establishment of a stable spatial coordinate system based on anterior cortex of femoral neck basilar.

Background: Frequent in-out-in femoral neck screws were reported potential huge iatrogenic-injury risks, related to axial safe target area (ASTA) of femoral neck screws channel. However, orientated-quantitative ASTA based on stable coordinate system was unreported before.

Methods: Three-dimensional reconstruction was performed on computed tomography (CT) images of 139 intact normal hips, and the intersection area, defined as ASTA, was obtained by superimposing the axial CT images of each femoral neck.

Post-Marketing Surveillance of Qishe Pill () Use for Management of Neck Pain in a Chinese Patient Cohort to Determine its Safety, Tolerability and Effectiveness.

Objective: To evaluate the safety and effectiveness of Qishe Pill () on neck pain in real-world clinical practice.

Methods: A multi-center, prospective, observational surveillance in 8 hospitals across Shanghai was conducted. During patients receiving 4-week Qishe Pill medication, Visual Analogue Scale (VAS) and Neck Disability Index (NDI) assessments have been used to assess their pain and function, while safety monitoring have been observed after 2 and 4 weeks.

Anatomic Restoration of Triple Disruption of the Superior Shoulder Suspensory Complex: A Case Report and Review of the Literature.

Background: Multiple disruptions of the superior shoulder suspensory complex (SSSC) involving more than two components are extremely rare. In some extreme situations, three components of the SSSC structure can be involved. The ideal treatment for this type of injury is debatable.

Management of Low-Energy Basicervical Proximal Femoral Fractures by Proximal Femoral Nail Anti-Rotation.

Objective: To evaluate clinical and radiological outcomes of proximal femoral nail anti-rotation (PFNA-II) devices and demonstrate the effectiveness of PFNA-II for the treatment of basicervical fractures in elderly patients.

Methods: A retrospective review of all patients treated with PFNA-II for a proximal femoral fracture between January 2013 and February 2017 at three different institutions (Shanghai General Hospital, Shanghai Punan Hospital and Shanghai Seventh People's Hospital) was conducted. The X-ray films were strictly reviewed by three trauma surgeons and a professional radiology doctor.

Surgical exposures of the distal humeral fractures: An anatomical study of the anterior, posterior, medial and lateral approaches.

Purpose: Exposure of the articular surface is the key to the successful treatment of intra-articular fractures of distal humerus. Anterior, posterior olecranon osteotomy as well as medial and lateral approaches are the four main approaches to the elbow. The aim of this study was to compare the exposure of distal articular surfaces of these surgical approaches.

[Biomechanics and imaging evaluation on stable structure of pelvis].

The treatment of difficulty and prognosis of pelvic fracture are directly related to the pelvic girdle stability. Diagnosis of pelvic fracture is mainly imaging manifestations based on biomechanics of pelvic anatomy. With the progress of biomechanics experiment technology, previousopinion has changed, such as separation of symphysis pubis 2.

[Treatment of distal femur nonunion with bone defect by less invasive stabilization system and fibular strut graft].

Objective: To evaluate the therapeutic effects of less invasive stabilization system distal femur (LISS-DF) combined with fibular struts graft for distal femur nonunions and bone defects.

Methods: A total of 12 patients with distal femur nonunion and bone defect were underwent revision operation with locked plating, plus a nonvascularized autologous fibular strut bone graft from June 2007 to September 2014, including 10 males and 2 females with an average age of (56.2±14.

[Comparison of the effect of total hip arthroplasty through mini invasive direct anterior approach during learning curve period and posterolateral approach for the treatment of femoral head necrosis].

Objective: To compare clinical results of treating femoral head necrosis staged Ficat III or IV with total hip arthroplasty (THA) between mini invasive direct anterior approach (DAA) and posterolateral approach.

Methods: From January 2008 to December 2009, 48 patients with femoral head necrosis staged Ficat III or IV treated with THA were compared and analyzed. There were 21 patients in mini invasive direct anterior approach group including 11 males and 10 females with an average age of (65.

[Assisting plate with reamed intramedullary nailing for segmental fractures of proximal-middle tibia].

Objective: To evaluate the efficacy and safety of combining reduction plating with reamed intramedullary nailing for segmental fractures of proximal-middle tibia.

Methods: From June 2007 to October 2011, 31 patients with segmental fractures of proximal-middle tibia were admitted. There were 18 males and 13 females, with an average age of 45.

Management of femoral diaphyseal nonunion after nailing with augmentative locked plating and bone graft.

Objectives: Exchange nailing (EN) for aseptic femoral shaft nonunion is currently a standard orthopaedic treatment modality. However, according to recent studies there is occasionally a high failure rate when EN is used. In the present study, augmentative locked plating and bone graft was used as an alternative method for treating such cases.

Treatment of aseptic diaphyseal nonunion of the lower extremities with exchange intramedullary nailing and blocking screws without open bone graft.

Objective: To report the preliminary results of the treatment of aseptic diaphyseal nonunion of the lower extremities with exchange nailing plus blocking screws.

Methods: Between June 2005 and September 2008, twelve patients with diaphyseal nonunion in the lower extremities (femur in five patients and tibia in seven; hypertrophic nonunion in eight patients and atrophic nonunion in four) were treated by reaming, exchanging the original intramedullary nail with a larger one, and using blocking screws, and the therapeutic effect assessed.

Results: All patients were followed up for 1-2 years (average, 1.

Induced endothelial cells enhance osteogenesis and vascularization of mesenchymal stem cells.

Adequate vascularization remains one of the major challenges in bone tissue engineering. Since the microvascular endothelium is of benefit to osteogenesis and vascularization when in direct contact with bone marrow mesenchymal stem cells (BM-MSCs), we investigated whether endothelial cells induced from BM-MSCs have the same effect on BM-MSCs in vitro and in vivo. BM-MSCs were isolated, characterized and induced into endothelial-like cells (induced endothelial cells, IECs) in endothelial cell growth medium 2.

The posterolateral shearing tibial plateau fracture: treatment and results via a modified posterolateral approach.

The posterolateral shearing tibial plateau fracture is relatively uncommon and few studies have concentrated on it so far. The purpose of this study was to review the results of surgical treatment of this kind of fracture using a modified posterolateral approach. The clinical results of a case series of 11 patients, collected prospectively, were presented here.
