Objective: To investigate the clinical value of continuous passive motion (CPM) and sodium hyaluronate (SH) in the patellar fracture patients postoperatively. Methods: Seventy - two cases of the patellar fracture were treated with SH and CPM machine postoperatively. Results: All of the patients experienced primary healing. The functions of the knee joint recovered well. All patients were followed up over six months,and none of them were found to have suffered from traumatic arthritis. Conclusion :The application of CPM and SH in the patellar fracture patients postoperatively has the satisfactory results of reducing pain,speeding up the healing of cartilage and improving the functions of knee joint. It is efficient to stop the process of traumatic arthritis following the patellar fracture.

Objective:To evaluate the effect of Extracorporeal Shock Wave combined percutaneous injection of enhanced fibrin glue loaded bone growth factor in accelerating the bone nonunion healing and promoting osteogenesis process .Methods: 48 radius model rabbits were randomly divided into four groups.Group A rabbits were treated with ESW;Group B rabbits were treated with ESW combined with FG;Group C rabbits were treated with ESW combined with FG/rhBMP-2/rhbFGF;Group D rabbits were treated with ESW combined with FG/rhBMP-2/rhbFGF/rhVEGF.After a combination therapy of 8 week,conventional X-ray radiography,optical in-spection organization form and biomechanical test were applied to evaluate the therapeutic effect .Results:Compared with the group B , the X-ray group C showed that the fracture line was fuzzy ,bony callus area began to increased ,fracture end range reduced.The histo-morphology showed that cartilage began to form , cartilage cell began to proliferate actively , and new blood vessels were forming surrounding fibrous connective tissue.Biomechanical determination found there was no statistical significance between the two groups ( P>0.05 ).FG/rhBMP-2/rhbFGF+ESW group showed the fracture line was still fuzzy , bony callus disappeared and apparent proliferative bone trabecula ,and biomechanical results showed that there was statistical significance between the two groups compared to the group B(P<0.01).FG/rhBMP-2/rhbFGF/rhVEGF+ESW group showed the fracture line was slightly fuzzy ,apparent proliferative bone trabecula in 4 week,and in 8 week,the fracture line was disappeared and moulding of healing was good.The histomorphology showed that the distribution was filled with fibrous connective tissue and many bone tissue .Biomechanical results showed that it could resistance to bending ,there was statistical significance between the two groups compared to the group C ( P<0.01 ).Conclusion: ESW therapy combined percutaneous injection of enhanced fibrin glue loaded bone growth factor can promote fracture healing and the method of combination is expected to be a good choice of non-surgical treatment of bone nonunion.

Objective To evaluate the clinical efficacy of radial head prosthesis replacement in treatment of comminuted fracture of the radial head and discuss relative operative announcements.Methods There were 27 patients with comminuted fracture of the radial head who were treated with radial head prosthesis replacement. Results Of all,26 patients were followed up for averaged 14months.According to Broberg score,the post-operative function was excellent in 9 patients(35%),good in 13(50%)and fair in 4(15%),with no poor results and with excellence rate of 85%. Conclusion Radial head prosthesis replacement can better restore the stability,flexion and extension of the elbow as well as the rotational motion of the forearm and is worthy of clinical application.

Objective To explore the curative effects of open reduction and internal fixation with Cable Pin or tension band wire for patellar transverse fractures.Methods Totally 28 cases and another 30 cases were enrolled in the Cable Pin group(8 months for average follow-up time) and the tension band wire group respectively(16 months for average follow-up time).The operative time,the average clinical healing time and the average range of the knee flexion between the 2 groups were compared.Results Obvious superiority was observed in the Cable Pin group over the tension band wire group concerning the average clinical healing time and the average range of the knee flexion 6 months postoperatively (P

Objective:To investigate the therapeutic effect of Chinese medicine combined with small dose of antidepressant on prospermia.Methods:150 cases of prospermia conformed to the diagnostic criteria were divided into 3 groups according to their wishes,50 cases in each group.Group I were treated with Zhibai Gujing Decoction,group Ⅱ with Sertraline hydrochloride,and group Ⅲ with Zhibai Gujing Decoction plus Sertraline hydrochloride,for 4 consecutive weeks.The ejaculatory latency,satisfaction degrees of sexual life,and the adverse effect of the medicine were observed.Results:After treatment,the ejaculatory latency was significantly prolonged and the satisfaction degree of sexual life was significantly increased in the 3 groups(P

Objective:To evaluate our self-made distraction reductor used in the percutaneous minimally invasive treatment of calcaneal fractures.Methods:A retrospective study was conducted of the 32 patients (37 feet) who had been treated at Department of Orthopaedics, The First Affiliated Hospital to Chongqing Medical University from January 2017 to December 2019 for calcaneal fractures. They were 26 males and 6 females, aged from 20 to 67 years (average, 46.5 years). The height and length of the calcaneus were restored by our self-made tri-plane distraction reductor in all patients; the displaced fracture blocks were reset in a minimally invasive manner in patients with intra-articular fracture; final fixation was performed with a minimally invasive plate and screws. Time for reductor installation, operation time and intraoperative blood loss were recorded; complications, fracture union and reduction were observed; height, length and width of the calcaneus, ankle-hindfoot scores of American Society of Foot and Ankle Surgery (AOFAS), Maryland scores, and visual analogue scale (VAS) were recorded at the last follow-up; B?hler and Gissane angles were compared between pre- and post-operation.Results:All patients were followed up for 12 to 36 months (average, 17.2 months). Time for reductor installation averaged 5.0 min (from 3 to 8 min), operation time 91.5 min(from 70 to 110 min), and intraoperative blood loss 25.2 mL (15 to 50 mL). Superficial infection of traction track occurred in one patient and sural nerve injury in one patient. All fractures united without any reduction loss by the last follow-up. On average, the last follow-up observed a calcaneal height of 39.3 mm, a calcaneal length of 70.6 mm, a calcaneal width of 32.7 mm, an AOFAS score of 87.8, a Maryland score of 86.7 and a VAS score of 2.2. The calcaneal B?hler angle was recovered significantly from 3.7°±13.7° preoperatively to 25.8°±6.4° at the last follow-up, and the calcaneal Gissane angle from 112.2°±21.3° preoperatively to 125.8°±5.7° at the last follow-up ( P< 0.05). Conclusion:In percutaneous minimally invasive treatment of calcaneal fractures, application of our self-made tri-plane distraction reductor can lead to fine clinical efficacy.
