ABSTRACT
BACKGROUND: Proximal humeral fracture is a common disease of fall injury in the elderly, because of bone nonunion after treatment with a variety of factors such as senile osteoporosis. Currently, the use of reverse total shoulder arthroplasty has achieved good clinical effect, but has certain limitations. OBJECTIVE: To compare and observe the clinical effects of reverse total shoulder arthroplasty and open reduction and internal plate fixation in the treatment of nonunion of proximal humeral fractures. METHODS: Totally 120 cases of nonunion of proximal humeral fractures were randomly divided into observation group and control group, with 60 cases in each group. The observation group received reverse total shoulder arthroplasty (replacement of artificial shoulder joint). The control group received open reduction and internal plate fixation. RESULTS AND CONCLUSION: (1) Follow-up results: At 3 years after surgery, the pain score was lower in the observation group than that in the control group (P < 0.05). Constant daily activities, range of activities, strength test score, Constant total score, satisfaction and hospitalization expenses were higher in the observation group than in the control group. Functions of flexion, laterotorsion and intorsion were better in the observation group than those in the control group (P < 0.05). (2) Adverse reactions: At 3 years after surgery, 26 and 22 cases had adverse reaction in the observation group and the control group respectively. (3) The results show that the clinical effect of the elders' nonunion of proximal humeral fracture treated with reverse total shoulder arthroplasty is quite good, and the pain degree and shoulder function are obviously improved. The curative effect of reverse total shoulder arthroplasty is better than that of open reduction and internal plate fixation.
ABSTRACT
This paper discusses variations of laparoscopic transgastric cystogastrostomy in management of retrogastric pancreatic pseudocysts for 8 patients with symptom or pseudocysts (larger than 6 cm) companied with clinical manifestations.Using a Harmonic scalpel,two 3-5-cm incisions were made in the anterior and posterior gastric wall respectively.In the last step,the anterior gastrotomy was closed with an Endo-GIA stapler.All cases were successfully treated without large blood loss and without conversion to open surgery.The mean operative time was 114.29±19.24 min,blood loss was 157.14±78.70 mL,and mean hospital stay was 8.29±2.98 days,Gastric fistula occurred in one case on the postoperative day 7,and closed 1 month later.No bleeding was seen in all patients during the perioperative follow-up period.CT scans,given one month after the surgeries,displayed that the pancreatic pseudocysts disappeared or decreased in size,and ultrasounds showed no fluid or food residue in stomas at the third and fifth month following surgery.No patient experienced a recurrence during the follow-up period.Transgastric laparoscopic cystogastrostomy is a minimally invasive surgical procedure with a high rate of success and a low rate of recurrence,accompanied by rapid recovery.It is easy to master,safe to perform and may be the preferred option to treat retrogastric pancreatic pseudocysts.
