During the experiments, no abnormal bleeding was found; the YUANHUA-TKA system ran smoothly and stably and was able to stop moving and keep the osteotomy in the safe zone all the time. After the experiment, the resection planes were observed immediately and found to be quite flat. There was no significant difference between the planned and actual osteotomy thickness and osteotomy angle ( >0.05); the error of the osteotomy thickness was less than 1 mm, and the error of the osteotomy angle was less than 2°. The YUANHUA-TKA system can assist the surgeons to perform osteotomy following the planned thickness and angle values. It is expected to assist surgeons to implement more accurate and efficient osteotomy in the future clinical applications.The YUANHUA-TKA system can assist the surgeons to perform osteotomy following the planned thickness and angle values.

To explore the gait trajectory characteristics and effectiveness after unicompartmental knee arthroplasty (UKA). Thirty patients (30 knees) with anterior medial compartment osteoarthritis who were treated with UKA between January 2017 and December 2018 were selected as subjects (UKA group). According to age, gender, and side, 30 patients (30 knees) with knee osteoarthritis treated with total knee arthroplasty (TKA) were selected as control (TKA group). In addition to the range of motion (ROM) before operation showing significant difference between the two groups ( =4.25, =0.00), there was no significant difference in gender, age, disease duration, sides, body mass index, and preoperative hip-knee-ankle angle (HKA), Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score between the two groups ( >0.05). read more The incision length, drainage volume within 24 hours after operation, and the changes of hemoglobin and albumin were recorded. The WOMAC score, ROM, and HKA before and after operand extension at mid-stance phase. From the analysis of gait symmetry, during the initial contact and loading response phase, the operation side after UKA undertakes more shock absorption and joint stabilization functions than the contralateral side.Compared with TKA, UKA has the advantages of small incision, less blood loss, and quicker functional recovery. The early gait after UKA is mainly manifested as the increase in walking speed, stride length, knee flexion at swing, and extension at mid-stance phase. From the analysis of gait symmetry, during the initial contact and loading response phase, the operation side after UKA undertakes more shock absorption and joint stabilization functions than the contralateral side. To investigate the effectiveness of percutaneous compression plate (PCCP) fixation for femoral neck fracture. A clinical data of 100 patients with femoral neck fractures who were treated with internal fixation were analyzed retrospectively. The fractures were fixed with the cannulated screws (CS) in 55 patients (CS group) and with the PCCP in 45 patients (PCCP group). There was no significant difference in gender, age, the cause of injury, the fracture type, complications, and disease duration between the two groups ( >0.05). The quality of fracture reduction, bone resorption, screw slipping, femoral neck shortening, complications (nonunion, failure of fixation, and osteonecrosis of femoral head), and functional recovery of hip (Harris score) were compared between the two groups. All incisions healed by first intention. All patients were followed up 24-56 months, with an average of 30.7 months. The quality of fracture reduction was excellent in 26 cases, good in 18 cases, fair in 9 cases, and poor gt;0.05). Stable sliding compression of PCCP is benefit for the femoral neck fracture healing, especially shortening union.Stable sliding compression of PCCP is benefit for the femoral neck fracture healing, especially shortening union. To compare the predictive value of the two concepts for complications by comparing the incidences of surgical complications associated with different tip-apex distance (TAD) and calcar referenced tip-apex distance (Cal-TAD) in the treatment of femoral intertrochanteric fractures with Asian type proximal femoral nail (APFN) fixation. A total of 188 cases of femoral intertrochanteric fractures treated with APFN fixation between January 2014 and December 2018 were collected according to inclusion criteria. TAD and Cal-TAD were measured on the X-ray film at immediate after operation; the patients were divided into two groups according to the measurement results <25 mm and ≥25 mm. Gender, age, and fracture side and AO type were recorded. The patients in each group were reviewed whether there was delayed fracture union or nonunion, whether the screw blade moved axially, whether the femoral neck collapsed or even screw blade cut out, whether the internal fixator became loose or broken within 12 months after ohe operation of femoral intertrochanteric fracture with APFN fixation, surgical complications can be significantly reduced when TAD or Cal-TAD was controlled within 25 mm, Cal-TAD is more significant in the prediction of postoperative complications.Instrument-processing staff work in a fast-paced, high-risk environment and errors in any of their processes can have a significant effect on patient safety. Effective communication is essential to the maintenance of complex processes such as the cleaning, disinfection and sterilisation of surgical instruments. This article details a service improvement project that aimed to evaluate staff members' perceptions of teamwork and communication before and after the implementation of team huddles in an instrument-processing department. A questionnaire was used to survey staff perceptions of teamwork and communication before and after the implementation of team huddles. The huddles included the use of a huddle board to standardise their content. While the survey did not identify any significant differences in staff perceptions before and after the implementation of the huddles, the department leaders noted significant improvements in the attitudes and engagement of staff members. The service improvement project demonstrated that structured team huddles can improve morale and efficiencies within departments through enhanced collaboration and communication.
