Objective To summarize the experiences of treatment of calculus obstructive pyonephrosis with transureteroscopic holium laser lithotripsy. Methods There were 13 patients with flank pain and fever, all patients received antibacterial therapy and nutritional support before operation ,the patients of calculus obstructive pyonephrosis were treated using transureteroscopic holium laser lithotripsy. Results The ureteral calculus were cleared off in 10 cases, and in three cases, the stone moved to pelvis during operation that they needed additional procedure of ESWL, no severe complications were observed.

This paper introduced the concept of wearable medical equipment, the development trend, a parti-cular way of gathering information and privacy protection from residential to people, to the development trend of da-ta-centric. Thus, this paper analyzes the information privacy protection of ethical challenges are: data has been weakened by the autonomy of the parties, the right to self-determination; The double-edged effect of wearable medical equipment increases the difficulty of the privacy protection, Has not been perfect wearable medical equip-ment behavior increase the difficulty of privacy protection. Privacy protection facing the challenge of wearable medi-cal devices for causes mainly include:commercial interests drive;Privacy violation cost greatly reduced. Doctor-patient information asymmetry, the patients privacy protection consciousness is weak. To solve above problems, and puts forward the countermeasures of information privacy protection:perfect wearable medical equipment's ethics and policies and regulations;improve the wearable medical devices the user's ego to protect consciousness;improve the wearable technology protection capabilities of medical equipment.

Objective To evaluate open reduction and internal fixation (ORIF) combined with Ilizarov joint distraction in the treatment of comminuted talar body fractures.Methods Between July 2010 and May 2016,16 patients with comminuted talar body fracture underwent ORIF followed by ankle joint distraction by Ilizarov external fixator at our department.They were 9 males and 7 females,aged from 17 to 56 years (average,35.6 years).Radiological assessments were conducted by plain radiographs and computed tomography (CT) scans pre-and post-operatively.Clinical outcomes were evaluated according to visual analogue scale (VAS),American Orthopedic Foot and Ankle Society (AOFAS) hindfoot score,the short form (SF)-36 health survey scores and patients' satisfaction.Results Two patients were lost to follow-up.The remaining 14 patients were followed up for an average duration of 33.3 months (from 13 to 52 months).All the fractures united.Superficial wound infection occurred in one case.Eight patients developed post-traumatic osteoarthris;4 patients presented with avascular necrosis.At final follow-ups,the AOFAS scores ranged from 30 to 97 points (mean,69.8 points),the VAS scores from 0 to 6 points (mean,2.5 points),the physical component summary in SF-36 from 18.0 to 55 points (mean,41.7 points),and the mental component summary from 40 to 70 points (mean,54.1 points).Two patients reported strong satisfaction,5 satisfaction,4 moderate satisfaction,and 3 dissatisfaction.Conclusion For comminuted talar body fractures,ORIF combined with Ilizarov joint distraction is a new and effective treatment which can not only provide adequate fixation strength but also reduce the incidence of post-traumatic osteoarthris or avascular necrosis.

Hepatocellular carcinoma (HCC) is a malignant tumor with a high incidence in China. Bone is a common extra hepatic metastasis site of HCC. Bone metastasis of HCC not only has a serious impact on the quality of life of patients, but also shortens their survival time. However, the pathogenesis of bone metastasis of HCC remains unclear. This review summarizes the clinical features, pathogenesis, prognostic factors, diagnosis and treatment progress and other aspects of bone metastasis of HCC, in order to provide new ideas for the clinical diagnosis and treatment.

Objective To analyze the clinical outcomes of a standard protocol of open reduction and internal fixation using a variable angle foot plate for a consecutive series of patients with acute Lisfranc joint injury.Methods This study retrospectively evaluated the clinical outcomes of 11 Chinese patients(13 feet) with acute Lisfranc joint injury who had been treated by open reduction and internal fixation with a variable angle foot plate from December 2016 to June 2017 at Department of Orthopaedics,West China Hospital.They were 8 men(10 feet) and 3 women(3 feet),aged from 19 to 57 years(average,36.4 years).Of them,10 were complicated with fracture of metatarsus,6 with cuneiform fracture and/or dislocation,4 with cuboid fracture,and one with cuboid fracture.According to the Myerson classification for Lisfranc fracture-dislocations,one case(one foot) belonged to type A,2(2 feet) to type Bl,5(6 feet) to type B2,2(3 feet) to type Cl and one(one foot) to type C2.The outcomes were evaluated using the visual analogue scale(VAS) and the midfoot scores of American Orthopedic Foot and Ankle Society(AOFAS).Results This cohort was followed up for 18 to 24 months(average,22 months).Their VAS scores were decreased significantly from preoperative 7.3±1.2(from 6 to 9) to postoperative 1.2±0.2(from 0 to 2)(P<0.05);their AOFAS midfoot scores were increased significantly from preoperative 0 to postoperative 84.6±4.6(P<0.05) Anatomic reduction was obtained in all the patients and all the fractures united successfully without any delayed union or nonunion.Superficial necrosis of the wound edge occurred in 2 cases without deep infection;skin anesthesia occurred in 2 and skin hypesthesia in 4,indicating a lesion of the superficial peroneal nerve.Conclusion Fixation of acute Lisfranc joint injury with a variable angle foot plate can lead to rigid stability,precise reduction and satisfactory short-term clinical outcomes.

Due to the complex anatomical structure of ankle and the various mechanisms of ankle injury, manyeponyms and systematic classifications of ankle fracture have been developed in the past centuries. Before the emergence and constant improvement of classifications of ankle fracture, ankle fractures were most commonly named afterthe physicians who first described them. Now,these ankle fracture eponyms are still found in medical literature, textbooks and even mass media. Many special named ankle fractures can be explained by the Lauge-Hansen classification now, and they may have little practical use. However, it is still necessary to summarize and review these ankle fracture eponyms, in order to correct the wrong usage of these and to remember the sages in this field.We reviewed both common and less frequently used ankle fracture eponyms, focusing on imaging features to identify and differentiate these injuries. We also briefly reviewed the mechanism of each injury, associated complications, its diagnosis and treatment.
