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 study the indications, methods, and therapeutic effect of absorbable rib-connecting-pins fixation in the treatment of multi ple rib fractures. Methods Between March 2007 and September 2009, 40 patients with multiple rib fractures received internal fixation with absorbable rib-connecting-pins, including 8 one-side flail chest and 1 twoside flail chest. There were 32 males and 8 females with an average age of 39.8 years (range, 25-72 years). The injury was caused by traffic accident in 32 cases, fall ing from height in 6 cases, and blunt hitting in 2 cases. Preoperatively, imaging data of the chest X-ray or spiral CT three-dimensional (3D) examination showed that all patients had multiple ribs fractures and displacement. The number of fractured ribs was 4-10 (median, 6), and the fracture location ranged from the 2nd to the10th ribs. Of them, 28 cases were accompanied by hemathorax, pneumathorax or hemopneumothorax; 5 cases by thoracic organ injury; and 10 cases byother part trauma. The time from injury to hospital ization was less than 1 day in 26 cases, 1-3 days in 12 cases, and 3-6 days in 2 cases, and the time from hospital ization to operation was 3 hours to 3 days (mean, 1.2 days). Results The median fixation rib number was 5 (range, 3-8). The mean operative time, the time in bed, and hospital ization days were 32 minutes (range, 15-50 minutes), 4.5 days (range, 2-7 days), and 11.2 days (range, 5-18 days), respectively. All incisions healed by first intention. No pulmonary infection, pulmonary atelectasis, intrathoracic infection or other compl ications occurred. All cases were followedup 6-12 months (mean, 8 months). PaO2 [(86.6 ± 2.2) mmHg (1 mm Hg=0.133 kPa)] and SpO2 (97.2% ± 0.6%) at 2 hours after operation were obviously improved when compared with preoperative ones [PaO2 (53.6 ± 4.7) mm Hg and SpO2 (86.2% ± 1.8%)], showing significant differences (t=2.971, P=0.005; t=2.426, P=0.020). The chest X-ray films or spiral CT 3D indicated that fracture of rib healed within 3-6 months (mean, 4.5 months) after operation. Conclusion Severe collapsed chest wall orflail chest caused by fracture of multiple ribs should be treated by absorbable rib-connecting-pins, which is a simple, firm, and effective method.
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.
ObjectiveTo use claw-shaped blade plate and self-made 'titanium clip' blade plate for rib fracture fixation, and compare outcomes of these two internal fixation methods through mechanical tests.
MethodsThoracic cage specimens of six adults (male)corpses were numbered. Bilateral 4th, 6th and 8th thoracic ribs of each corpse were taken from the rib nodules (0%)to costal cartilage junction (CJJ points, 100%)along the long axis of the ribs. Rib fragments about 130 mm in length with 50% locus were selected for mechanical tests of the lateral area. A total of 36 rib fragments were sampled and numbered. Each rib fragment was placed on electronic universal mechanical tester. A span of 100 mm and a loading speed of 2.5 mm/min were set to perform a three-point bending test until specimens fractured. The loads at displacement of 2, 4, 6, 8, 10, 15 and 20 mm respectively and maximum load were recorded, then the load-displacement curve was drawn. Above rib fragments were randomly divided into 2 groups, which were fixed using 'titanium clip' blade plate (titanium plate group)and claw-shaped blade plate (claw-shape group)respectively. Three-point bending test was performed under above loading conditions until the fixed specimens fractured again, and relevant data were recorded.
ResultsBefore fixation, there was no statistical difference in maximum load and peak deformation of the 4th, 6th and 8th ribs between the 2 groups (P > 0.05). Maximum load and peak deformation of the 4th, 6th and 8th ribs in the claw-shape group after fixation were statistically different from those before fixation (P < 0.05). Maximum load and peak deformation of the 4th, 6th and 8th ribs in the titanium plate group after fixation were also statistically different from those before fixation (P < 0.05). After fixation, maximum loads of the 4th, 6th and 8th ribs in the claw-shape group were statistically different from those in the titanium plate group (P < 0.05), but there was no statistical difference in peak deformation between the 2 groups (P > 0.05).
ConclusionsFractured ribs fixed with 'titanium clip' blade plates are more stable and stronger than those fixed with claw-shaped blade plates.
Objective To evaluate clinical efficacy of four-claw Ti-planes for internal fixation of multiple rib fractures and flail chest. Methods Clinical data of 93 patients with multiple rib fractures and flail chest who were admittedto Shanghai Pudong Hospital from December 2011 to November 2012 were retrospectively analyzed. There were 78 male and 15 female patients with their age of 20-80 years. All the patients received internal fixation of rib fractures using four-clawTi-planes. Finite element modeling and analysis were performed to investigate biomechanical behaviors of rib fractures after internal fixation with four-claw Ti-planes. Results The average number of rib fractures of the 93 patients was 5.9±2.1，and each patient received 3.8±1.3 four-claw Ti-planes for internal fixation. The operations were performed 6.3±3.2 days after admission. After the rib fractures were fixed with four-claw Ti-planes，rib dislocations and chest-wall collapse of flail chest were restored，and patients’ pain was relieved. Postoperative CT image reconstruction of the chest showed no dislocationor displacement at the fixation areas of the four-claw Ti-planes. Rib fractures were stabilized well，and normal contours of the chest were restored. Finite element analysis showed that the maximum bearable stress of the rib fractures after internal fixation with four-claw Ti-planes was twice as large as normal ribs. Conclusion Clinical outcomes of four-claw Ti-planesfor internal fixation of rib fractures are satisfactory with small incisions and less muscle injury of the chest wall，so this technique deserves wide clinical use.
