The femurs of 98 Chinese fetuses were observed and measured with radiographic method. A series data of femur-length and -width of different fetal-age groups was obtained. Calculated femur index (width/length?100)showed that the proportion between the femural length and the femural width remained considerably constant dur- ing the development of the fetus. The positive correlation between the length of the femur and the C-R length was revealed by statistical analysis; a regression equation was obtained. The authors suggest that it is possible to take the femural length as a criterion parameter to estimate the fetal age.

Objective To explore the clinical effects of pyloroplasty on proximal gastrectomy in patients with lesions in cardia of the bottom of stomach.Methods One hundred cases of the proximal gastric diseases who were enrolled in the second affiliated hos-pital of Chongqing medical university from the January 2010 to December 2013 were selected in this prospective randomized con-trolled experimental study.Among them,6 cases were excluded,and the other 94 cases were divided into two groups:the experimen-tal group (A),in which 54 patients were underwent additional pyloroplasty surgery;the control group (B),in which 40 patients were underwent with no strings attached pyloroplasty.All patients were followed up.Then,the clinical indicators during hospitaliza-tion,term complications and repeated endoscopy prompted pyloric stenosis and reflux esophagitis situation three months after dis-charged from hospital were observed.Results There was no significant difference in the incidence rate of gastroplegia (P >0.05);there were significant differences in other clinical indicators during the postoperative hospitalization and the incidence rate of compli-cations (P <0.05).Conclusion Proximal gastrectomy additional pyloroplasty could reduce gastric retention,decrease the incidence of reflux esophagitis,shorten the hospital period and could be helpful for recovery,thus it is recommended to be further promoted.

Objective To study the accuracy of the anteversion of femoral prosthesis in hemiarthro-plasty for treating femoral intertrochanteric fracture in the elderly.Methods Twenty femoral neck antever-sions of specimens were measured, which were control group(A).The femoral specimens were made into the model of femoral intertrochanteric fracture, which were installed femoral prosthesis according to minor trochanter(B),identifying the max diameter of cavum medulla(C),ocular estimating femoral condylar line ( D) ,combination of identifying the max diameter of cavum medulla and ocular estimating femoral condylar line( E) respectively.All the anteversion of femoral prosthesis were measured.Results The anteversion were:A group(8.98 ±4.31)°,B group (9.12 ±4.87)°,C group (9.57 ±6.49)°,D group (13.18 ± 5.83)°,E group (10.37 ±4.56)°respectively.The difference among the five groups was statistically sig-nificant.There was difference between D and A, there were no differences between B and A, C and A, E and A respectively.Conclusions In hemiarthroplasty for treating femoral intertrochanteric fracture, the an-teversion of femoral prosthesis is according to minor trochanter possibly; if the minor trochanter can not be got reduction, it is a good option according to combination of identifying the max diameter of cavum medulla and ocular estimating femoral condylar line to make sure the accuracy of the anteversion of femoral prosthe-sis.

Objective To investigate the clinical outcomes of arthroscopic rotator cuff repair using improved-press-ift double-row technique for patients of large rotator cuff tear.Methods From December 2013 to November 2014, 52 patients (20 males, 32 females) with a full-thickness large rotator cuff tear underwent arthroscopic improved-press-ift double-row repair were retrospectively analyzed. The mean age of the patients was 65.6 years (range 51 to 76 years). The visual analog pain scale scores (VAS), the range of motion (ROM), University of California at Los Angeles (UCLA), and American Shoulder and Elbow Surgeons (ASES) were used for clinical and functional evaluations before surgery and at the time of 6 months after arthroscopy.Results The mean duration of follow-up was 10.9 months (range 6 to 17 months). At the time of 6 months after arthroscopy, the mean subjective pain score (VAS) was (1.6 ± 0.9), the mean active forward flexion was (145.6 ± 10.7)°, whereas the mean external rotation at the side was (30.8 ± 8.5)°. The mean UCLA score improved to (32.3 ± 3.5), the mean ASES score improved to (81.8 ± 8.7). There was significant difference postoperatively (P < 0.05). No re-tear occurred.Conclusion The improved-press-ift DR technique is effective in arthroscopic large rotator cuff repairing. Compared with suture-bridge technique, this technique can decrease operation time, costs, and is much easier to process.

During the postoperative follow -up period,the incidence rate of complications of the observation group (4.00%) was significantly lower than the control group (24.00%)(χ2 =4.15,P <0.05).Conclusion For patients with level of Ⅲ meniscus tear,arthroscopic FaxT -Fix technology vertical mattress suture can effectively reduce the surgery and hospitalization time,promote functional recovery of the patients 'knee,significantly improve the postoperative Lysholm knee score and IKDC,but also significantly reduce postoperative wound infection,hematoma,nerve damage vascular complication rate.

Objective To investigate the clinical and pathological characteristics, diagnosis and treatment of gastric cancer with ovarian metastasis. Methods The clinical data of 17 cases of gastric cancer with ovarian metastasis, confirmed by surgery and pathology, were analyzed retrospectively. Results The average age of the patients was 48.41 years, and the first appearance of symptoms and signs often were of metastatic ovarian cancer. The main ultrasonographic findings were either a complex type of mass with both solid and cystic characteristics or only solid, and most of them were accompanied by intraperitoneal fluid accumulation. Bilateral metastatic ovarian cancer was more common(13 cases). The preoperative accurate diagnosis of this disease was difficult, so that the misdiagnostic rate was 64.7% in this series. Operation was done in all the patients, but prognosis was poor. The median survival time was only 11.6 months. Conclusions The prognosis of gastric cancer with ovarian metastasis is poor. It is of importance to inspect the stomach in cases of bilateral ovarian cancer. Radical resection of the primary disease focus together with hysterectomy and bilateral adnexectomy should be performed. Postoperative comprehensive therapy is conducive to improve the prognosis of gastric cancer with ovarian metastasis.

Objective To compare the clinical results of arthroscopic rotator cuff repair using a suture bridge technique and conservative therapy as treatment of traumatic shoulder dislocation combined with rotator cuff injury in older patients. Methods From August 2010 to August 2013 a total of 63 patients were prospectively enrolled. In the case of documented tears of the rotator cuff in combination with symptoms persisting after conservative therapy, patients were free to decide between arthroscopic rotator cuff repair using a suture bridge technique and conservative treatment. Patients were monitored for changes in visual analogue scale (VAS) scores, range of motion, the Simple Shoulder Test (SST), the Constant score and recurrences over a minimum follow-up period of 1 year. Results 60 pa-tients (30 in surgical group and 30 in conservative treatment group) were follow-up for at least 1 year. There was no significant difference between the two groups at baseline. The surgical group resulted in better improvements in pre-operative to postoperative VAS scores, range of motion, SST scores and the Constant score. There were five recur-rences in the conservative treatment group, while no recurrences were documented in surgical group. Conclusion In this selected patient group, we believe arthroscopic repair using a suture bridge technique for the treatment of symp-tomatic rotator cuff tear can improve shoulder function and decrease recurrences in older patients suffered from trau-matic shoulder dislocation combined with rotator cuff injury. The long-term outcomes remain to be determined.
