To analyze the incidence and characteristics of fabella in the Chinese population and its correlation with pain in the posterolateral region of the knee joint and common peroneal nerve palsy.

Total 732 patients including 405 males(450 knees) and 327 females(383 knees) who underwent unilateral or bilateral knee MR imaging from September 2015 to July 2019 were retrospectively evaluated. The basic information of all patients was extracted from the hospital's his system. The patient's medical records were checked by telephone follow-up or his system, and the number of patients with posterolateral knee pain and common peroneal nerve paralysis were recorded.

The overall prevalence of fabella was 48.38%, 23.53% in men and 24.85% in women, there was no significant difference between them (

>0.05). All the subjects were divided into five age groups. The prevalence of fabella was significantly different among different age groups6.6% in 20 year-old group, 33.8% in 21 to 34-year-old group, 53.5% in 35 to 44-yeThe prevalence of fabella us in Chinese population is 48.38%. There is no relationship between the incidence of gastrocnemius and gender, but the incidence of fabella is positively correlated with age, pain in the posterolateral region of the knee joint and the occurrence of common peroneal nerve symptoms.

To investigate the effect of intra-articular injection of tranexamic acid on blood loss and blood transfusion rate after minimally invasive unicompartmental knee arthroplasty.

From January 2015 to September 2017, 90 patients underwent minimally invasive unicompartmental knee arthroplasty were divided into tranexamic acid group and control group, 45 cases in each group. In the tranexamic acid group, there were 22 males and 23 females, aged 62 to 69 (66.1±2.4) years;in the control group, 20 males and 25 females, aged 63 to 71(68.5±5.2) years. SGI-110 mw The amount of bleeding in the drainage ball at 48 hours after operation was recorded, and the blood transfusion rate and hematocrit level duringthe perioperative period were recorded. The factors influencing perioperative blood loss included gender, age and body mass index (BMI).

All patients were followed up for 12.5 to 28.3 (22.8±7.9) months. During the follow-up, the wounds of the two groups healed well, and no deep vein thrombosis and pulmonary embolism occurred. There was no significant difference in postoperative blood loss between the tranexamic acid group and the control group. The postoperative bleeding volume in the tranexamic acid group was (110.0±52.1) ml, and that in the control group was (123.0±64.5) ml (P=0.39). There was no blood transfusion in the two groups.

Intra articular injection of tranexamic acid can not significantly reduce the postoperative blood loss in patients with minimally invasive unicompartment.

To compare the effect of traditional fibula flap combined with allogeneic bone transplantation and composite bone flap transplantation combined with bone lengthening in staged repair of severe soft tissue and bone defect caused by lower limb burn.

Total 68 patients with severe soft tissue and bone defect caused by lower limb burn from March 2015 to January 2018 were retrospectively analyzed, and they were divided into control group (34 cases) and study group (34 cases) according to the treatment plan. All patients had different degrees of soft tissue and bone tissue defects. In the study group, 34 patients were treated with composite bone flap transplantation combined with bone lengthening. There were 22 males and 12 females; the age ranged from 32 to 46(39.18±6.01) years; the time from injury to treatment was (16.69±5.11) h;28 cases were caused by explosion injury and 6 cases were caused by firearm burn; the length of bone defect was (12.10± 2.34) cm;and 16 cases were on the left side of affected limb 18ol group (76.47%)(

<0.05), the treatment satisfaction of the study group (94.12%) was higher than that of the control group(76.47%)(

<0.05). Complicationsthe incidence of complications in the study group (14.71%) was higher than that in the control group (26.47%) (

>0.05).

the combined use of composite bone flap transplantation and bone lengthening staged repair in the treatment of severe soft tissue and bone defect caused by lower limb burn can achieve good therapeutic effect, improve limb function, and have high treatment satisfaction and certain safety.

To investigate the clinical effect of titanium cable assisted fixation combined with lengthened Gamma nail in the treatment of subtrochanteric fracture of femur.

From January 2010 to January 2018, 45 patients with long subtrochanteric fractures were retrospectively analyzed, and they were divided into two groups according to the operation plan. There were 24 cases of titanium cable assisted fixation combined with lengthened Gamma nail (observation group), including 14 males and 10 females, with an age of (54.2±12.8) years; 21 patients (control group) were treated with simple lengthened Gamma nail (control group), including 12 males and 9 females, with an age of (51.4±15.9) years. The operation time, intraoperative blood loss, hospital stay, hemoglobin decrease and fracture healing time were observed and recorded in the two groups. Harris hip function score was used to evaluate the postoperative curative effect, and the occurrence of complications was observed.

All patients were followed up for 14 to 36 months.
