RESUMO
Objective:To investigate the correlations between subacromial impingement syndrome (SIS) and acromial morphology and subacromial intervals after surgery of proximal humerus fracture.Methods:A retrospective study was conducted of the 62 patients with proximal humerus fracture who had been treated by internal fixation with a locking titanium plate from December 2014 to December 2019 at Department of Orthopedics, People's Hospital of Gaoming District. They were 40 men and 22 women, with an average age of 53.5 years (from 35 to 71 years). By the Neer classification, there were 38 three-part and 24 four-part fractures. The incidence of SIS was determined by Nikolaus's diagnostic criteria. The patients were divided into a SIS group and a non-SIS group. The acromial morphology was observed and the subacromial intervals [acromio-greater tuberosity of humerus interval (AGI) and acromio-plate interval (API)] were measured on postoperative X-ray films. The correlations were analyzed between them and SIS.Results:All patients completed treatments and follow-ups from 3 to 15 months (average, 10 months). There was no incision infection or internal fixation failure. There were 18 cases in the SIS group and 44 ones in the non-SIS group. In the SIS group, 3 cases had type Ⅰ acromion while 15 ones type Ⅱ or type Ⅲ acromion; in the non-SIS group, 20 cases had type Ⅰ acromion while 24 ones type Ⅱ or type Ⅲ acromion. The proportion of patients with type Ⅱ or type Ⅲ acromion in the SIS group was significantly higher than that in the non-SIS group ( P<0.05). AGI and API in the SIS group were (11.6±2.1) mm and (14.2±2.4) mm, significantly shorter than those in the non-SIS group [(15.7±2.8) mm and (18.5±3.2) mm] ( P<0.05). Conclusions:SIS is a common complication after surgery of proximal humerus fracture. Abnormal acromial morphology (type Ⅱ or type Ⅲ acromion), poor fracture reduction (reduced AGI), and high placement of a titanium plate (reduced API) may be all important factors leading to SIS.
RESUMO
Objective To evaluate the clinical efficacy of the modified Stoppa approach in the surgical treatment of pelvic fractures of Tile type C combined with acetabular both-column fractures.Methods Between April 2014 and April 2017,a total of 14 patients were treated by open reduction and internal fixation (ORIF) through the modified Stoppa approach at Department of Orthopaedics,Foshan Gaoming Hospital for pelvic fractures of Tile type C combined with acetabular both-column fractures.They were 10 men and 4 women,with an average age of 36.4 years (from 23 to 57 years).The modified Stoppa approach was used exclusively in 4 cases,in combination with the iliac fossa approach in 3 ones,in combination with the Kocher-Langenbeck approach in 4 ones and in combination with the Kocher-Langenbeck and iliac fossa approaches in 3 ones.In all the patients,the pelvic reconstructive plate and screws and lag screws were used.The operation time,intraoperative bleeding volume,postoperative fracture reduction,fracture union time,efficacy and complications were recorded.Results The operation time averaged 170 min (from 110 to 330 min) and the intraoperative bleeding 420 mL (from 240 to 1 100 mL).There were no operative complications.By the Matta evaluation,the postoperative reduction was rated as excellent in the 14 pelvic fractures and 9 acetabular both-column fractures and as good in 5 acetabular both-column fractures.Of this series,13 patients were followed up for an average of 19 months (from 12 to 29 months) and one was lost to the follow-up.The fractures got united after an average time of 3.4 months (from 2.7 to 4.6 months).Screw loosening was observed in one case and mild limitation to hip flexion in one.Follow-ups found no lateral ventral syndrome or femoral head necrosis.Their Harris hip scores at the last follow-up ranged from 70 to 94 points,averaging 84 points.The function of the affected hip was excellent in 6 cases,good in 5 and fair in 2.Conclusion The modified Stoppa approach may be used exclusively or in combination with other approaches to treat effectively the pelvic fractures of Tile type C combined with acetabular both-column fractures,leading to good short-term clinical outcomes.

RESUMO
Objective To compare the curative effect of percutaneous endoscopic lumbar discectomy (PELD) and microendoscopic discectomy (MED) in lumbar disc herniation.Methods A literature search was performed in PubMed, Web of Science, Embase, Wanfang, CNKI. Two authors reviewed all articles individually. The methodological quality of RCTs was assessed by the Cochrane risk of bias tool, and the quality of retrospective studies was evaluated by the modified Newcastle-Ottawa scale. The data was extracted by the Review Manager 5.30.Results A total of 19 articles were brought into this Meta-analysis. The outcomes were divided into primary outcomes and secondary outcomes. Excerpt for the short-term VAS score was lower in PELD group (P = 0.010), other index, including long-term VAS score (P = 0.120), ODI score (P = 0.260), complication (P = 0.100) and recurrence (P = 0.100), didn't had significant difference in two groups. The blood loss (P = 0.000), hospital stay (P = 0.000) and the length of incision (P = 0.000) were all superiority in PELD group. Whereas the operative time was shorter in MED group (P = 0.001).Conclusion PELD was a more minimally invasive and secure technique in lumbar disc herniation.
