ABSTRACT
Objective To investigate the promoting effect of local compression and fixation on the healing of anterior tibial flask-like wound after debridement and suture.Methods A retrospective case control study was conducted to analyze the clinical data of 57 patients with simple anterior tibial flask-like wound admitted to the Second Hospital of Shandong University from May 2017 to June 2018.There were 32 males and 25 females,aged 20-60 years [(41.4 ± 8.1) years].The length of wound ranged from 1 to 10 cm.All patients had only acute skin and soft tissue injury,without any fracture,large area skin defect,large area avulsion injury,or chronic diseases such as diabetes mellitus and lower limb vascular disease.The study group contained 37 patients who were treated with local pressure dressing and limb fixation after debridement and suture while the control group included 20 patients who were treated with simple dressing after debridement and suture.At 3,5,7,14,and 21 days after operation,the size of the wound,the type and quantity of exudate,the color of skin around the wound and the type of wound tissue were compared,and the healing time was recorded.Results All patients were followed up for 30-90 days [(52.2 ± 3.5) days].Three days after operation,there was no significant difference between the two groups (P ＞0.05).On the 5th day after operation,the scores of exudate amount,skin color surrounding wound and tissue types of the wound bed in the control group and the study group were (4.2 ± 0.7) points ∶ (3.3 ± 0.6) points,(3.5 ± 0.7) points ∶ (2.5 ± 0.6) points,(3.4 ± 0.6) points ∶(2.5 ± 0.5) points (P ＜ 0.05),but there was no significant difference between the two groups in the scores of the size of wound and the type of exudate (P ＞ 0.05).On the 7th day after operation,the scores of the size of wound,type of exudate,amount of exudate,skin color around the wound and the type of wound tissue in the control group and study group were (3.5 ± 0.5) points ∶ (2.5 ± 0.7) points,(3.4 ±0.7)points ∶ (2.4 ±0.5)points,(4.0±0.8)points ∶ (2.8 ±0.5)points,(3.4 ±0.5)points ∶ (1.3 ±0.5) points,(3.3 ± 0.5) points ∶ (2.1 ± 0.4) points (P ＜ 0.05).On the 14th day after operation,the scores of the scores of the size of wound,type of exudate,amount of exudate,skin color around the wound and the type of wound tissue in the control group and study group were (2.9 ± 0.6)points ∶ (1.2 ±0.7)points,(2.8 ±0.7)points ∶ 0 point,(3.3 ±0.7)points ∶ (1.0 ±0.0)points,(3.1 ±0.6)points ∶(1.1 ± 0.4) points,(3.0 ± 0.6) points ∶ (1.2 ± 0.5) points (P ＜ 0.05).Twenty-one days after operation,the scores of the scores of the size of wound,type of exudate,amount of exudate,skin color around the wound and the type of wound tissue in the control group and study group were (2.5 ±0.7)points ∶0 point,(2.5 ±0.5)points ∶ 0 point,(3.0 ±0.7)points ∶ (1.0 ±0.0)points,(2.6±0.7)points ∶ (1.1 ±0.3) points,(2.6 ± 1.1) points ∶ 0 point (P ＜ 0.05).The wound healing rate was 100％ in both groups.The wound healing time of the control group and the study group was (28.3 ± 6.7) days and (15.2 ± 0.9) days respectively (P ＜ 0.05).Conclusion For anterior tibial flask-like wound,local pressure bandaging and fixation after debridement and suture can significantly promote wound healing compared with conventional simple bandaging,with the advantages of better healing quality and shorter healing time.
ABSTRACT
Objective@#To investigate the promoting effect of local compression and fixation on the healing of anterior tibial flask-like wound after debridement and suture.@*Methods@#A retrospective case control study was conducted to analyze the clinical data of 57 patients with simple anterior tibial flask-like wound admitted to the Second Hospital of Shandong University from May 2017 to June 2018. There were 32 males and 25 females, aged 20-60 years [(41.4±8.1)years]. The length of wound ranged from 1 to 10 cm. All patients had only acute skin and soft tissue injury, without any fracture, large area skin defect, large area avulsion injury, or chronic diseases such as diabetes mellitus and lower limb vascular disease. The study group contained 37 patients who were treated with local pressure dressing and limb fixation after debridement and suture while the control group included 20 patients who were treated with simple dressing after debridement and suture. At 3, 5, 7, 14, and 21 days after operation, the size of the wound, the type and quantity of exudate, the color of skin around the wound and the type of wound tissue were compared, and the healing time was recorded.@*Results@#All patients were followed up for 30-90 days [(52.2±3.5) days]. Three days after operation, there was no significant difference between the two groups (P>0.05).

ABSTRACT
Objective To explore the intraoperative fluoroscopy in percutaneous sacroiliac screw fixation based on anatomic measurement and digital reconstructed CT data. Methods The CT data of the pelvis at prostration were collected for 3D reconstruction of the pelvic models from 30 patients with injury to the pelvis or acetabulum.Then the anatomical boundaries of thesafe zone of sacroiliac screw insertion were marked on the 3D models,including the upper,front and back cortex boundaries of S1 vertebra,the front and bottom cortex boundaries of sacral foramen area,and the sacral alar slope. The angles between these anatomical boundaries and the pelvic baseline were measured on the sagittal plane.The digital reconstructed radiology (DRR) was applied to form the inlet,outlet and lateral images of fluoroscopy.The standard protocol to acquire accurate intraoperative images was analyzed by characterization of important anatomic landmarks.Results The angles between the upper,front and back cortex boundaries of S1 vertebra and the baseline (αl,α2,α3) were respectively 37.7°± 8.6°(from 23.2°to 50.8°),22.9° ± 6.7° (from 13.1° to 32.0°),41.9°± 6.8° (from 33.0°to 54.8°).The angles between the front and bottom cortex boundaries of sacral foramen area and the baseline (α4,α5) were 37.0°± 12.0° (from 19.9° to 63.1°) and 38.8°± 8.0° (from 25.7°to 54.6°).The angle between the alar slope and the baseline (α6) was 82.4°± 13.0°(from 70.3°to117.3°).The characteristic manifestations of important anatomic landmarks were observed in the simulated fluoroscopy images. Conclusions It is recommended that the projecting angles in the inlet and outlet views should be decided according to the specific data of each patient.Because the alar slope can not be clearly identified in the outlet view due to its large inclination,the position of screw insertion should be verified in the lateral view to prevent the screw from penetrating the slope to hurt the L5 nerve and iliac vessels.
