RESUMO
Objective To explore the somatotype characteristics and rules of Lisu and Dulong adolescents aged 13-18 years, and to analyze their annual somatotype differences. Methods According to the method of human bod)' measurement, through the measurement of 10 related indexes, using Heath-Carter bod)' type evaluation method, 634 cases (328 boys, 306 girls) Lisu and Dulong teenagers bod)' type evaluation. Results The average bod)' size of male and female students of Lisu ethnic group was of balanced mesoderm type (2. 9-4. 8-3. 3) and endoderm type (4. 7-4. 8-2. 8) . The average body size of male and female students of Dulong nationality is mesoderm type (3 . 1-3. 9-2. 1) and mesoderm type (5 . 2 - 4 . 6 - 1 . 6) . Among the 10 test indexes, there were significant differences in height, body weight, intercondylar diameter of humerus and intercondylar diameter of femur (P < 0. 01) . There were significant differences in height, intercondylar diameter of humerus and intercondylar diameter of femur among female students (P<0. 0 1) . Conclusion In Yunnan Province, adolescents of Lisu and Dulong ethnic groups generally have the body type characteristics of southern ethnic groups, but the body type difference between the two ethnic groups is great, and only has the characteristics of similar stage, age and body type.
RESUMO
OBJECTIVE@#To investigate the accuracy and safety of pedicle screw placement assisted by orthopedic robot and C-arm fluoroscopy.@*METHODS@#The clinical data of 36 patients with spinal diseases underwent surgical treatment from January 2019 to August 2020 was retrospectively analyzed. Among them, 18 cases were implanted pedicle screws assisted by orthopaedic robot(observation group), including 12 males and 6 females, aged from 16 to 61 years with an average of (38.44±3.60) years;there were 1 case of adolescent scoliosis, 1 case of spinal tuberculosis, 7 cases of lumbar spondylolisthesis, 4 cases of thoracic fracture and 5 cases of lumbar fracture. Another 18 cases were implanted pedicle screws assisted by C-arm fluoroscopy(control group), including 10 males and 8 females, aged from 18 to 58 years with an average of (43.22±2.53) years;there were 1 case of adolescent scoliosis, 6 cases of lumbar spondylolisthesis, 6 cases of thoracic fracture and 5 cases of lumbar fracture. The intraoperative fluoroscopy times, nail placement time and postoperative complications were recorded in two groups. CT scan was performed after operation. The Gertzbein-Robbins standard was used to evaluate the accuracy of pedicle screw placement which was calculated.@*RESULTS@#The number of intraoperative fluoroscopy in observation group was(6.89±0.20) times, which was significantly higher than that in control group(14.00±0.18)times(P<0.05). The placement time of each screw in observation group was(2.56±0.12) min, which was significantly different from that in control group(4.22±0.17) min (P<0.05). One case of incision infection occurred in control group after operation, and recovered after active dressing change. During the follow-up period, no serious complications such as screw loosening and fracture occurred in two groups, and there was no significant difference in complications between two groups(P>0.05). A total of 107 screws were placed in observation group, including 101 screws in class A, 4 in class B, 2 in class C, 0 in class D and 0 in class E, the accuracy rate of pedicle screw placement=[(number of screws in class A+B) / the number of all screws placed in the group] ×100%=98.1%(105/107); and a total of 104 screws were placed in control group, including 90 screws in class A, 4 in class B, 5 in class C, 5 in class D and 0 in class E, the accuracy rate of pedicle screw implantation=[(number of screws in class A+B/the number of all screws placed in the group]×100%=90.3% (94/104); there was significant difference between two groups (P<0.05).@*CONCLUSION@#Orthopaedic robot assisted pedicle screw placement has the advantages of less fluoroscopy times, shorter screw placement time and higher accuracy, which can further improve the surgical safety and has a broad application prospect in the orthopaedic.

Total en bloc spondylectomy is a surgical technique cutting off tumors of spine and its satellite. Previous studies have shown that this technique could reduce postoperative recurrence rate of spinal tumor, but surgical indications are not unified. Wide application of spinal tumor surgical staging and life expectancy system make it more clear for surgery. However, it is difficult to carry out extensive operation for the characteristics of more bleeding, great difficulty and high risk. As for continuous improvement of TES technology, application of endoscopy and appearance of 3D printing artificial vertebral body could push the operation becoming mature.

RESUMO
Madelung deformity is a rare deformity of forearm and wrist caused by growth disorders of distal radius ulnar and palmar epiphyseal. Current studies showed that its incidence mainly associated with trauma, epiphyseal developmental abnormalities, nutritional disorders and genetic deletion or mutation. The early clinical presentation is not typical, in middle and late time, wrist deformity and weak can appear. Plain film considered as the main means of diagnosis is often lack of early diagnosis significance. Although wrist joint magnetic resonance imaging showing early soft tissue and skeletal abnormalities were used for the early diagnosis of the disease, current domestic study in magnetic resonance imaging of this deformity is less. According to the size of the distal ulnar inclination angle and palm angle, this deformity can be divided into different types. The patients with severe deformity and symptoms usually need surgical intervention including ulna revision and osteotomy of the distal radius at present. Although the two operation can achieve good clinical results, the surgical trauma, infection and postoperative risk of joint activities are more.

<p><b>OBJECTIVE</b>To explore clinical efficacy of closed reduction and external fixation under local anesthesia for the treatment of high-risk elderly patients with intertrochanteric fracture.</p><p><b>METHODS</b>From March 2013 to March 2015, 10 patients with intertrochanteric fractures treated with closing reduction and external fixator under local anesthesia were analyszed, including 4 males and 6 females, aged from 69 to 88 years old with an average of 75.2 years old. All fractures were caused by injury and classified to type I (5 cases), II (3 cases), and V (2 cases) according to Evans classification. According to American Society of Anesthesiologists (ASA), 6 cases were type III and 4 cases were type IV. Blood loss,operative time,hospital stays, postoperative complications, ambulation time and fracture healing time were observed, and Harris scoring were used to evaluate hip joint function.</p><p><b>RESULTS</b>All patients were followed up from 3 to 23 months with an average of 13.1 months.

There were no coxa vara, lower limb venous thrombosis, loosen and remove of needle passage. The average operative time was 46 min, blood loss was (35.00 ± 8.46) ml without blood transfusion. One patient was occurred pulmonary infection and stent-tract infection on the 2 nd and 3 rd day after operation, and improved with active anti-infection and dressing change; the other patients gone to ground activity at 4.2 d after operation. The patients stayed hospital for 10.6 d on average. According to Harris scoring at final following-up, the total score was 83.42 ± 3.27, 3 cases obtained excellent results, 5 cases good and 1 case poor.</p><p><b>CONCLUSION</b>Closed reduction and external fixation under local anesthesia in treating high-risk elderly patients with intertrochanteric fracture,which has advantages of shorter operative time, less blood loss, good recovery of postoperative function, is a safe, stable and economic method.</p>
