ObjectiveTo investigate the efficacy and safety of internal rib fixation for patients with multiple rib fractures. MethodsA total of 141 patients with multiple rib fractures who were admitted to Department of Thoracic Surgery of the Sixth Affiliated Hospital of Xinjiang Medical University between January 2010 and January 2013 and whose chest trauma score (AIS-ISS) was 9-20 (16±2) were recruited in this study. Using the random number generator of SPSS, all the patients were randomly divided into an internal fixation group [69 patients including 41 males and 28 females with their age of 25-61 (37±4) years] who underwent internal rib fixation, and a control group [72 patients including 43 males and 29 females with their age of 24-63 (35±5) years] who received conservative therapy. Plasma C-reactive protein (CRP) patients' satisfaction degree with thoracic appearance,incidence of lung infection,pain-relieving efficacy,postoperative chest drainage duration and length of hospital stay were compared between the 2 groups. ResultsPlasma CRP levels of the internal fixation group were not statistically different from those of the control group in 1-3 days after injury (P>0.05) but were significantly lower than those of the control group in 4-12 days after injury (P<0.05). Patients' satisfaction degree with thoracic appearance (97.1% vs. 48.6%,P<0.05) and pain-relieving efficiency (91.3% vs. 68.1%,P<0.05) of the internal fixation group were significantly higher than those of the control group. Incidence of lung infection of the internal fixation group was significantly lower than that of the control group(11.6% vs. 37.5%,P<0.01). Postoperative chest drainage duration [(3±2) d vs. (7±4) d,P<0.05] and length of hospital stay [(9±4) d vs. (15±7) d,P<0.05] of the internal fixation group were significantly shorter than those of the control group. ConclusionsFor patients with multiple rib fractures and stable vital signs,internal fixation surgery is helpful to shorten length of hospital stay, relieve chest pain and improve thoracic appearance. It can also reduce lung inflammation and increase surgical safety so as to improve treatment outcomes of multiple rib fractures.
Objective To access the possibil ity of CPC as a suitable scaffold for tissue engineering artificial rib by morphologic observation, adhesion experiments and cellar prol iferation experiments. Methods The 5 mm × 5 mm × 5 mm CPCs were prepared and the structure and components of CPC were compared with those of the normal human bone by micro-CT and scanning electron microscope. Bone marrow aspirates were harvested from the young pig and monuclear cells were separated. The first passage cells were collected and re-suspended in the culture media at a density of 6 × 105 cells/mL. There was 150 μL suspension which was incoluated on the CPC, and then cells were recollected and counted 4, 12 and 24 hours after inoculation. MTT was used to examine the growth condition of BMSCs on the surface of CPC. The scanning electron microscope was used to observe the CPC scaffold 7 days after inoculation, and comparison was made with CPC and the normal human bone. Results The adhesion rate of CPC was 28.00% ± 0.98%, 46.70% ± 1.14% and 48.50% ± 1.18%, respectively 4, 12 and 24 hours after compound culture. The prol iferation rate of CPC was 1.103 ± 0.214, 1.557 ± 0.322, 1.920 ± 0.178, 2.564 ± 0.226, 2.951 ± 0.415 and 3.831 ± 0.328, respectively 1, 2, 3, 4, 5 and 6 days after compound culture, with an obvious rising trend. The micro-CT demonstrated that the content of hydroxyapatite of porous phosphate calcium was (1 101.222 8 ± 0.618 4) mg/ ccm while that of the normal human bone was (1 072.552 3 ± 0.744 2) mg/ccm, and the porosity of porous phosphate calcium was 70.26% ± 0.45% while that of the normal human bone was 72.82% ± 0.51%, and there was no significant difference (P gt; 0.05). The experiment of cell prol iferation showed that the cell which was cultivated with porous phosphate calcium prol iferated rapidly. Through the inverted phase contrast microscope, it was found that the cells grew well and there was no dead cell, which indicated that the material had no toxicity. The rate of the cell adhesion to CPC was less than 50%. Conclusion The structure and components of CPC are similar to those of the normal human bone, and BMSCs grow well on the surface of it, so it is asuitable scaffold for tissue engineering artificial rib. However, the cell adhesion abil ity is to be further improved.

ObjectiveTo explore the feasibility to use pain scale and arterial oxygen partial pressure(PaO2)as screening internal fixation indications for patients with multiple rib fractures. MethodsClinical data of 48 patients with multiple rib fractures who were admitted to Shanghai Pudong Hospital from September 2010 to February 2013 were retrospectively analyzed. Visual analogue scale (VAS) was used for pain assessment. Twenty-four patients whose VAS was greater than or equal to 6 and PaO2 was less than 60 mm Hg 3 days after injury were chosen as the experimental group, including 16 males and 8 females with their age of 49.29±15.73 years. Another 24 patients whose VAS was less than or equal to 5 and PaO2 was greater than 60 mm Hg 3 days after injury were chosen as the control group, including 19 males and 5 females with their age of 48.63±13.49 years. Patients in both groups received rib internal fixation with steel plates. Three days and 1 week after surgery respectively, VAS and PaO2 were compared between the 2 groups. ResultsIn the experimental group, VAS 3 days after surgery was significantly lower than preoperative VAS (4.09±0.93 vs. 8.21±1.18, P < 0.05), and VAS 1 week after surgery was significantly lower than preoperative VAS (3.20±0.98 vs. 8.21±1.18, P < 0.05). In the control group, there was no statistical difference between VAS 3 days after surgery and preoperative VAS (P > 0.05), and there was no statistical difference between VAS 1 week after surgery and preoperative VAS (P > 0.05). Three days after surgery, PaO2 of the experimental group was significantly higher than preoperative PaO2 (61.00±3.47 mm Hg vs. 53.00±3.97 mm Hg, P < 0.05). There was no statistical difference between PaO2 3 days after surgery and preoperative PaO2 in the control group (66.71±5.15 mm Hg vs. 66.00±5.00 mm Hg, P > 0.05). Three days after surgery, pneumonia occurred in 4 patients in the experimental group and 2 patients in the control group (χ2=0.762, P > 0.05). Three days after surgery, pain scale reduction of the experimental group was significantly higher than that of the control group (4.13±1.45 vs. 0.00±0.42, P < 0.05). One week after surgery, pain scale reduction of the experimental group was significantly higher than that of the control group (5.04±1.23 vs. 0.08±0.28, P < 0.05). Three days after surgery, PaO2 increase of the experimental group was significantly higher than that of the control group (7.42±3.59 mm Hg vs. 0.21±0.98 mmHg, P < 0.05). ConclusionIt's reasonable and feasible to use pain scale greater than or equal to 6 and PaO2 less than 60 mm Hg as internal fixation indications for patients with multiple rib fractures.
Objective To investigate the tunnel-type open reduction and internal fixation of rib fractures (ORIF) with titanium locking plate in traumatic rib fractures. Methods Clinical data of 10 patients with multiple rib fractures from June 2016 to January 2017 in the Sixth People’s Hospital Affiliated to Shanghai Jiaotong University were analyzed. There were 6 males and 4 males with an average age of 38.5±9.0 years (range, 30–63 years). All patients underwent emergency treatment, chest CT and ultrasound examination before they admitted to the hospital. According to rib fractures and injuries, patients were given the tunnel-type ORIF of rib fractures with titanium locking plates, the chest tube and negative suction drainage. The patients were followed up over three months. Results All patients were cured. There was no complication during follow-up. No wound infection and death occurred. Postoperative three-month follow-up showed that chest pain was significantly relieved without pulmonary atelectasis and pleural effusion or other complications. Conclusion Tunnel-type internal fixation of rib fractures with titanium locking plates is effective, which can quickly restore the stability and integrity of the thorax. Surgical procedure is simple and can get fast postoperative recovery to improve the patient's quality of life.
