Objective:To investigate the effect of the placement of a drainage tube on the prognosis of patients with pelvic fractures treated by modified Stoppa approach.Methods:The medical records of patients with pelvic fractures treated with modified Stoppa approach from August 2012 to August 2017 were retrospectively analyzed. A total of 43 patients including 32 males and 11 females (mean age 47.6 years, range from16 to 69) were included in the study. According to Young-Burgess classification, there were 12 cases of Lateral Compression type LC-I type; 20 cases of Anterior and Posterior Compression type APC-I type and 11 cases of APC-II type. All patients were treated with modified Stoppa approach to reduce the fracture and fix with plate and screw. According to whether a drainage tube was placed during the operation, 22 cases were placed with a drainage tube (drainage group), and 21 cases were not placed with a drainage tube (non-drainage group). The main observation indicators were the intraoperative conditions, antibiotic application, incision suture removal time, postoperative body temperature change, hospital stay and clinical function (Harris score).Results:Wound infection was not observed in two groups. The duration of antibiotic use in the drainage group was 5.0 d (2.0, 8.0) d, and the non-drainage group was 4.0 d (2.0, 5.0) d, the difference was not statistically significant ( Z=1.161, P=0.924). The hospital stays of the two groups were 18.5 d (15.0, 24.3) d and 19.0 d (13.0, 26.0) d, respectively, and the difference was not statistically significant ( Z=0.542, P=0.591). The operation time was 150.2±52.4 min in the drainage group and 138.8±41.2 min in the non-drainage group, and the difference was not statistically significant ( t=0.791, P=0.433). The blood loss in the drainage group was 604.6±387.3 ml, and the non-drainage group was 581.0±275.0 ml. The difference was not statistically significant ( t=0.276, P=0.784). The postoperative body temperature changes of patients in the drainage group and non-drainage group were on day 1 (37.5±0.5 ℃ vs. 37.4±0.4 ℃, t=0.322, P>0.05), day 3 (37.1±0.4 ℃ vs. 37.0±0.4 ℃, t=0.286, P>0.05), day 5 (37.0± 0.3 ℃ vs. 36.8±0.2 ℃, t=2.127, P>0.05), on the 7th day (36.8±0.2 ℃ vs. 36.7±0.4 ℃, t=0.491, P>0.05), the difference was not statistically significant. The time for suture removal of surgical incision was 14.1±0.6 d in the drainage group and 13.9±0.6 d in the non-drainage group, and the difference was not statistically significant ( t=1.072, P=0.329). The Harris scores of the two groups were 96 (91, 100) points for the drainage group and 96 (93, 97) points for the non-drainage group, and the difference was not statistically significant ( Z=0.107, P=0.607). Conclusion:There is no significant influence of the application of drainage on recovery of wound or function for patients with pelvic surgery.

Objective:To establish a model of patellar dislocation by femoral osteotomy or surgical release of medial retinaculum in immature rabbits, and observe morphological and trabecular microarchitectural changes in the trochlea.Methods:Forty rabbits at 3 months of age were included. All right knees underwent surgery, 20 knees were treated with femoral osteotomy and internal rotation of distal femur to increase femoral anteversion angle (Osteotomy group, OS group), and another 20 knees were treated with surgical release of medial retinaculum and overlap suture of lateral retinaculum (Soft tissue group, ST group). All left knees were acting as internal controls. Micro-CT scans for distal femur were acquired after 4 months post surgery. the height of Medial, central, and lateral trochlear, sulcus angle, and lateral and medial trochlear slope were measured to describe the trochlear morphology, and bone volume fraction (BV/TV), trabecular thickness (Tb.Th), trabecular number (Tb.N), trabecular spacing (Tb.Sp), and bone mineral density (BMD) were calculated to evaluate the microarchitectural structure. All parameters were compared between groups.Results:In OS group, one rabbit sustained a hip dislocation without patellar dislocation. Three knees developed complete patellar dislocation in daily flexion position, and the remaining 16 patellae were dislocated when the knee was placed in the maximal extension position. In ST group, 15 knees were complete patellar dislocation in daily flexion position, and 5 knees were without dislocation. A local boss was formed proximal to the entrance of the groove and the articular cartilage was smooth, and no obvious osteoarthritis was observed in OS group. In ST group no boss was formed, while obvious cartilage degeneration and defect was seen. Compared to the control group, the central trochlear height and sulcus angle were greater in both groups, but without significant difference between the two groups. The Tb.Th was increased in both medial and lateral condyle, and Tb.N was decreased in medial condyle compared with its control knees in OS group. The BV/TV, Tb.Th, Tb.N and BMD were decreased and Tb.Sp was increased in both medial and lateral condyle compared with its control knees in ST group. Compared to the OS group, the BV/TV, Tb.Th, Tb.N and BMD were smaller and Tb.Sp was greater in both medial and lateral condyle in ST group, with significant differences.Conclusion:The model of patellar dislocation could be successfully achieved by femoral rotational osteotomy to increase femoral anteversion or surgical release of medial retinaculum and overlap suture of lateral retinaculum, and subsequent morphological and trabecular microarchitectural changes in the trochlea are different. Different bony and soft tissue factors should be addressed for different patients with patellar dislocation in clinical practice.

Objective To explore the clinical outcome an anatomic quadrilateral surface plate for both?column acetabu?lar fractures through the Stoppa combined with iliac fossa approach. Methods A retrospective study of the patients with both?col?umn acetabular fractures treated with an anatomic quadrilateral surface plate through the Stoppa combined with iliac fossa ap?proach from November 2015 to June 2017 was performed. Nineteen patients including 16 males and 3 females met the inclusion criteria. The mean age of included patients was 49.11 years (range, 25-68 years). There were 8 cases of fall injury, 7 cases of car accident injury and 4 cases of crushing injury. There were 11 cases of C1 type injury, 7 cases of C2 type, and 1 case of C3 type ac?cording to Tile classification. Patients included in this study were both?column acetabular fractures according to Letournel?Judet classification. There were six cases associated with posterior wall detachment. Minimally Stoppa combined with iliac fossa ap?proach was performed to manage the displaced fragments. First, the anteromedially displaced iliopubic fragment was managed with a reconstruction plate through iliac fossa approach. Then, the medially displaced ischiadic fragment could be fixed with an anatom?ic quadrilateral surface plate through the Stoppa approach. The reduction quality was assessed by postoperative radiographs and CT scans according to the criteria proposed by Matta. The function of hip joint was assessed by the Merle d’Aubigné?Posteal score modified by Matta. Results The average operation time and blood loss were 115.26 min (range, 90-160 min) and 534.21 ml (range, 300-1000 ml), respectively. The mean length surgical incision was 18.82 cm(range, 16-20 cm). Average follow?up time was 19.84 months (range, 12-28 months). According to Matta criteria of reduction quality, anatomic reduction was obtained in 14 cases, and satisfactory reduction was gained in 3 cases, while unsatisfactory reduction was found in 2 cases (satisfactory rate= 89.47%). All fractures healed well and mean healing time was 3.32 months (range, 3-5 months). The mean Merle d’Aubigné?Post?eal score modified by Matta was 16.95 (range, 13-18), including 12 cases of excellent, 4 cases of good, and 3 cases of fair (satisfac?tory rate=84.21%). Intraoperative injury of lateral femoral cutaneous nerve developed in a case and obturator nerve damage oc?curred in another patient, respectively. Relevant symptoms were totally disappeared after two months’conservative treatment (in?cluding neurotrophic therapy combined with adduction exercise of the affected thigh). Iliac fossa hematoma occurred in a case and relevant symptom was eliminated after puncture. Conclusion Satisfactory clinical outcome of both?column acetabular fractures could be obtained by the anatomic quadrilateral surface plate through the Stoppa combined with iliac fossa approach.

Objective@#To evaluate the possibility of transverse sacroiliac screw placement in different segments of the sacrum.@*Methods@#Data of 80 pelvic CT scans (slice thickness ≤1.0 mm) archived in CT department of the Third Hospital of Hebei Medical University from September 2016 to October 2017 were retrospectively collected. Mimics software was used to rebuild the pelvis three-dimensional model. According to whether the sacral 1(S1) segment could place the transverse sacroiliac screws or not, all the sacrums were divided into normal group (n=55) and dysmorphic group (n=25). Simulation the S1, sacral 2(S2) transverse sacroiliac screw placement in 3-Matic software. Analysis whether there was any difference in maximum diameter and length of S2 transverse sacroiliac screw between the normal group and the dysmorphic group. The pelvic CT data of the dysmorphic group were measured, and the optimal tilt angle and length of the oblique S1 screw were obtained. The feasibility of transverse sacroiliac screw insertion in sacral 3(S3) segment was evaluated.t-test, rank sum test, and χ2 test was used to analyze data, respectively.@*Results@#In the dysmorphic group, the largest diameter of the S1 transverse screw was (4.9±1.6)mm, and the normal group was (13.6±3.6)mm (t=-15.07, P=0.00). In the dysmorphic group, the largest diameter of S2 transverse screw was (13.8±3.0)mm, and was (12.4±2.2)mm in the normal group(t=2.11, P=0.04). There was no significant difference in the length of S2 transverse sacroiliac screw between the two groups (t=0.47, P=0.64). In the dysmorphic group, the anterior vertebral height of S1 was (23.1±4.0)mm, which was significantly higher than that of the normal group ((14.1±4.2)mm)(t=9.01, P=0.00). The angle of S1S2 in the dysmorphic group was 10.9°(3.8°, 17.6°), which was significantly larger than that of the normal group (2.0°(1.0°, 2.0°) (Z=-4.03, P=0.00). In the dysmorphic group, the incline angle of the oblique S1 sacroiliac screw was (35.6±6.2)°, the anteversion angle was (37.2±4.4)°, and the mean screw length was (90.2±4.7)mm. In the dysmorphic group, the placement rate of S3 transverse sacroiliac screw was 48.0%, and that of the normal sacral group was 9.1%.@*Conclusions@#There is often dysmorphic in the sacrum in patients with large S1 anterior vertebral height and S1S2 angle. Sacral dysmorphic patients with posterior pelvic ring injury may be treated with S1 pedicle oblique sacroiliac screws. S3 transverse sacroiliac screws should be carefully placed, especially for the absence of sacral dysmorphic in patients.
