ABSTRACT
OBJECTIVE@#To evaluate the efficacy of long reconstruction plate combined with minimally invasive percutaneous plate osteosynthesis(MIPPO) technique in the treatment of unstable pelvic anterior ring fractures.@*METHODS@#From January 2013 to February 2019, 16 patients with unstable pelvic fracture were treated, including 12 males and 4 females, aged from 20 to 60 years(mean 46.5 years). According to Tile classification, there were 4 cases of type B1, 6 cases of type B2, 4 cases of type C1 and 2 cases of type C2. The fracture of all patients was closed, and the time from injury to operation was 7 to 10 days with an average of 6.2 days. The operation time, intraoperative blood loss, fracture reduction quality, fracture healing time, complications and limb function during the final follow-up were evaluated in 16 patients.@*RESULTS@#All 16 patients were followed up for 12 to 23 months (mean 19.1 months). The operation time was 60 to 180 min (mean 107.8 min). The intraoperative blood loss was 120 to 600 ml (mean 368.1 ml). The fracture healing time was 12 to 20 weeks (mean 16.3 weeks). According to Matta criteria, the fracture reduction was excellent in 6 cases, good in 8 cases and fair in 2 cases. One patient suffered from lateral femoral cutaneous nerve injury during the operation, and the lateral thigh sensation decreased after operation, which recovered after 6 months. One patient had pain stimulated by internal fixation at the iliac fossa. The symptoms were improved after the internal fixation was removed. The fractures of 16 patients were healed satisfactorily and there was no internal fixation loosening. Majeed score at the final follow-up was 67 to 95, excellent in 10 cases, good in 4 cases and fair in 2 cases.@*CONCLUSION@#Closed reduction and fixation of pelvic anterior ring fracture with long reconstruction plate combined with MIPPO technique through anterior approach has the advantages of less injury, less bleeding time during operation, saving operation time, high intraoperative safety, high fracture healing rate, early functional exercise after operation, and effective treatment of pelvic anterior ring fracture.

OBJECTIVE@#To assess the clinical efficacy of minimally invasive technology with trajectory screw fixation for fragility fractures of pelvic(FFP).@*METHODS@#A retrospective case control study was performed to analyze the clinical data of 35 patients with FFP who were treated and followed up between January 2016 and December 2019. There were 12 males and 23 females, aged from 65 to 99 years with an average of(75.4±7.8) years old. There were 13 cases of type Ⅱb, 7 cases of type Ⅱc, 8 cases of type Ⅲa, 2 cases of type Ⅲb, 2 cases of type Ⅲc, 1 case of type Ⅳb, and 2 cases of type Ⅳc according to Rommens FFP comprehensive classification. All patients received the treatment of minimally invasive technology with trajectory screws fixation. According to the different methods of anterior pelvic ring fixation, FFP patients were divided into two groups:12 cases were fixed with the pedicle screw rod system in the anterior pelvic subcutaneous internal fixator (INFIX) group;23 cases were fixed with hollow screws of the pubic symphysis, superior ramus of pubis or acetabular anterior column in the screw group. The operation time, intraoperative blood loss, intraoperative fluoroscopy times, length of hospital stay, cost of internal fixation, pre- and post-operative visual analogue scale(VAS) were compared between the two groups. The fracture reduction quality was evaluated according to the Matta criteria, and the clinical function was evaluated by the Majeed functional scoring system respectively.@*RESULTS@#All patients were followed up for 12 to 39(16.5±5.4) months after surgery. There was no statistically significant difference in the operation time, intraoperative blood loss, intraoperative fluoroscopy time, and length of hospital stay between the two groups(P>0.05). As for the cost of internal fixation, the cost of internal fixation in the screw group [2 914 (2 914, 4 371) yuan] was significantly lower than that of the INFIX group [6 205 (6 205, 6 205) yuan] (P<0.05). No significant difference was observed in the incidence of postoperative complications between the two groups (P>0.05). There was no significant difference in VAS assessment at admission, 1 week, and 3 months after surgery between the two groups(P>0.05). However, the VAS assessment at 1 week and 3 months after surgery of the two groups were significantly better than those at admission(P<0.05). There was no significant difference in the quality of fracture reduction after the operation and the efficacy evaluation at the last follow-up between the two groups(P>0.05).@*CONCLUSION@#For the treatment of fragility fractures, minimally invasive technology with trajectory screw fixation can achieve good clinical efficacy. It has the advantages of being relatively minimally invasive, less bleeding, relieving the pain. It deserves clinical application.

Objective:To investigate the characteristics of fragility fractures of pelvis(FFP) in the elderly and compare the clinical efficacy between conservative treatment and minimally invasive surgery.Methods:A retrospective study was conducted in the 56 elderly FFP patients who had been treated at Department of Orthopaedics, The General Hospital of Chinese People＇s Liberation Army from January 2017 to January 2019. They were 16 males and 40 females, with an age of 73.4 years (from 65 to 93 years). By the American Society of Anesthesiologists (ASA) classification, there were 12 cases of grade Ⅰ, 16 cases of grade Ⅱ, 20 cases of grade Ⅲ, and 8 cases of grade Ⅳ; by the FFP classification, there were 6 cases of type Ⅰ, 10 cases of type Ⅱ, 36 cases of type Ⅲ, and 4 cases of type Ⅳ. The morphological characteristics and injury mechanisms of FFP were analyzed. According to the treatment methods, the patients were divided into a conservative treatment group of 32 cases and a minimally invasive surgery group of 24 cases. The 2 groups were compared in terms of complication incidence, mortality and the Koval attenuation rate of walking ability after one-year follow-up.Results:There were mostly the fractures of pubic branches on both sides of the pubic symphysis and compression fractures of the sacral wing caused by lateral crush injury. The 2 groups were comparable due to no significant differences in the preoperative general data between them other than FFP classification ( P>0.05). By one year after treatment, the conservative treatment group had a complication incidence of 34.4% (11/32), a mortality of 9.4% (3/32) and a Koval attenuation rate of walking ability of 13.8% (4/29) while the minimally invasive surgery group had a complication incidence of 20.8% (5/24), a mortality of 4.2% (1/24) and a Koval attenuation rate of walking ability of 8.7%(2/23), showing no significant difference between the 2 groups ( P>0.05). Conclusions:The injury mechanism of geriatric FFP is mostly lateral compression injury. The fracture sites are mostly located on both sides of the pubic symphysis, pubic branches and the sacral wing of anterior and posterior rings simultaneously. Although there may be no significant difference in complication incidence, mortality or Koval attenuation rate of walking ability between conservative treatment and minimally invasive surgery after one year, the minimally invasive surgery deals with more unstable fracture types.
ABSTRACT
Objective To evaluate the safety and accuracy of modified percutaneous retrograde intramedullary screwing into the superior pubic ramus or anterior acetabular column for pelvic and acetabular injury.Methods A retrospective analysis was conducted of the 23 patients with pelvic and acetabular injury who had been treated with modified percutaneous retrograde intramedullary screwing into the superior pubis ramus or anterior acetabular column from June 2015 to June 2017 in Luoyang Orthopaedic Hospital of Henan Province.They were 12 men and 11 women,aged from 22 to 88 years (mean,53 years).The injury included 17 pelvic fractures,4 acetabular fractures,and 2 acetabular plus pelvic fractures.The safety and accuracy of screwing were assessed by postoperative physical and imaging examinations.The number of fluoroscopy and operative time were documented for each retrograde intramedullary screwing into the pubic symphysis or acetabular anterior column.The quality of fracture reduction was evaluated by the Mata criteria postoperatively.The Majeed and the Harris scores were used to evaluate the functional recovery of the pelvis and acetabulum at the last follow-ups.Results A total of 31 intramedullary screws were placed in the 23 patients.For insertion of one screw,the operative time ranged from 15 to 50 min (average,35 min) and the number of fluoroseopy from 32 to 55 times (average,45 times).Postoperative physical examinations revealed no iatrogenic neurovascular lesion and uneventful healing of incisions in all the patients.Postoperative imaging examinations showed that 29 screws were located completely in the bone and 2 ones protruded the cortical bone of the pubic anterior border;all the screws did not protrude into the acetabulum or broke through the pubic symphysis or the pubic cortex.By the Matta criteria,the postoperative fracture reduction was rated as excellent in 17 cases,good in 5 and fair in one,giving an excellent to good rate of 95.7％.Of this series,19 were followed up for 6 to 24 months (mean,13 months).All the fractures healed after 3 months.The Majeed scores at the last follow-up for the 13 patients with pelvic fracture were excellent in 12 and good in one.The Harris scores at the last follow-up for the 6 patients with acetabular fracture (including the 2 with pelvic fracture) were excellent in 5 and fair in one.Conclusion The modified percutaneous retrograde intramedullary screwing into the superior pubic ramus or anterior acetabular column is safe,convenient and precise,effectiyely reducing radiation and operative time.
ABSTRACT
Robot-assisted laparoscopic radical cystectomy (RARC) for the treatment of muscle invasive bladder cancer is being increasingly applied. Radical cystectomy is complex procedure which should be performed with extensive lymph node dissection and urinary diversion. Currently, the techniques of RARC are well-described, and the feasibility and safety of RARC has been demonstrated. While extracorporeal approach is preferred method for urinary diversion, intracorporeal urinary diversion is gaining popularity. Positive surgical margins are similar to large open series but inferior for locally advanced disease. However, local recurrence and survival rates seem equivalent to open series at short and mid-term follow up. Randomized controlled trial should be conducted to rigorously assess the oncologic outcomes of RARC compared to open radical cystectomy.

Objective To study the clinical value of VACORA vacuum-assisted rotation system in the treatment of benign breast lesions. Methods Under the screening of dynamic ultrasound,122 beast lesions in 93 patients diagnosed as benign lesions from ultrasound were treated with VACORA vacuum-assisted rotation system,and all the patients were examined for follow-up. Results All the lesions were totally rotated and 119 lesions demonstrated to be benign and 3 lesions were atypical hyperplasia from pathologic examination. In the benign lesions, 72 cases were demonstrated to be fibroadenoma, 39 cases were demonstrated to be fibrosis adenosis,4 cases were intraductal papilloma,2 cases were duct inflammation, 1 case was epithelial hyperplasia of the duct and 1 case was lymphode. In 8 cases,bleeding was seen along the needle tract,which was stopped after compression. Small hematoma was formed in 10 patients in the second day of follow-up, which was disappeared in the 3 to 6 months of the follow-up. And all patients had no remnant lesions in the local area and the incisions were not clear in the skin 3 to 6 months of the follow-up. Hypoechoic focuses were detected out at the original location in the 3 benign cases, which were possibly residual focuses. Conclusions Benign breast lesions could be clearly resected with VACORA rotation system under the screening of ultrasound, which is safe, minimal invasive, prosthetic, and has little complications.
