  • PERCUTANEOUS FIXATION OF PELVIC FRACTURE BY Acutrak FULL THREAD HEADLESS HOLLOW COMPRESSION SCREW

    【Abstract】 Objective To evaluate the effectiveness of percutaneous fixation of pelvic fracture by Acutrak full thread headless hollow compression screw. Methods Between March 2008 and April 2010, 31 patients with pelvic fracture underwent percutaneous fixation surgery with Acutrak full thread headless hollow compression screw (surgical group). The effectivenss was compared with those of 14 patients with pelvic fracture treated conservatively (control group). There was no significant difference in age and sex between 2 groups (P gt; 0.05). The injury was more severe in surgical group than in control group. The standard of short-term recovery was active turning over and walking for 5 steps with walking aids. The standard of long-term recovery was pain, gait, fracture healing, and function recovery. Results In surgical group, the other patients reached the standard of short-term recovery at 1-4 days after injury except 1 patient who had sacral plexus injury; in control group, the patients could turn over at 9-13 days (Tile type A2) and 17-25 days (Tile type B2) respectively, and could walk at 17-21 days (Tile type A2) and at 45-57 days (Tile type B2) respectively. The patients of 2 groups were followed up 6-19 months. The time of fracture healing was 2-6 months. The long-term results were excellent in 29 cases and good in 2 cases in surgical group, and were excellent in 8 cases and good in 6 cases in control group, showing significant difference between 2 groups (χ2=6.636, P=0.017).Conclusion Percutaneous internal fixation combined with Acutrak full thread headless hollow compression screw can provide more effective treatment. It can alleviate patients, pain quickly, improve life quality, and has better long-term effectiveness.

  • SURGICAL TREATMENT OF MOREL-LAVALLÉE LESION WITH PERINEAL LACERATIONS

    Objective To investigate the surgical treatments of Morel-Lavallée lesion with perineal lacerations. Methods From March 2003 to June 2009, 18 cases of Morel-Lavallée lesion with perineal lacerations were treated. There were 16 males and 2 females with a median age of 28.5 years (range, 3-54 years). The time between the injury and hospital ization ranged from 3 hours to 7 days. The lesions were in the greater trochanter (2 cases), the gluteal (2 cases), the lumbar flank (1 case), the lumbar sacrum (3 cases), the pelvic girdle (7 cases), and the hip (3 cases). All the cases were compl icated with perineal lacerations, which included male genital ia defect (2 cases), mangled genital ia (2 cases), and genital ia injuries with anal injuries (14 cases). The main treatments included repeated debridement, external fixation of fractures, vacuum seal ing drainage, skin grafting, reconstruction of genital ia, and anoplasty. Results Three cases died after operation. Two cases died of multiple system organ failure, 1 case died of septic shock. Three cases were amputated and the causes were mangled extremities (2 cases) and osteofascial compartment syndrome (1 case). In 15 survivors, the average time of operations was 3.6 times (range, 3-8 times) and the average hospital ization days was 43.3 days (range, 32-108 days). After a follow-up of 6 months to 2 years, all perineal wounds healed. Anals recovered the normal defecation while one with ostomy was waiting for the secondly resetting of the bowels. Conclusion The treatments of Morel-Lavallée lesion with perineal lacerations were significantly different from simple close Morel-Lavallée lesion. With high mortal ity and disabil ity, Morel-Lavallée lesion with perineal lacerations require more challenging treatment protocols among which the most important is the soft tissue management and nutrition. The satisfactory outcomes come from joint efforts of multiple departments.

  • Effectiveness analysis of three-dimensional printing assisted surgery for unstable pelvic fracture

    ObjectiveTo evaluate the effectiveness of three-dimensional (3D) printing assisted internal fixation for unstable pelvic fractures.MethodsThe clinical data of 28 patients with unstable pelvic fractures admitted between March 2015 and December 2017 were retrospectively analyzed. The patients were divided into two groups according to different surgical methods. Eighteen cases in the control group were treated with traditional anterior and posterior open reduction and internal fixation with plate; 10 cases in the observation group were treated with 3D printing technology to make pelvic models and assist in shaping the subcutaneous steel plates of the anterior ring. Sacroiliac screw navigation template was designed and printed to assist posterior ring sacroiliac screw fixation. There was no significant difference between the two groups in gender composition, age, cause of injury, fracture type, and time interval from injury to surgery (P>0.05). The operation time, intraoperative blood loss, intraoperative fluoroscopy times, incision length, waiting time for weight-bearing exercise, and fracture healing time were recorded and compared between the two groups. Majeed score was used to evaluate the function at last follow-up. At immediate after operation, the reduction was evaluated according to Matta imaging scoring criteria, and the success of sacroiliac joint screw implantation in the observation group was evaluated. The deviation of screw entry point and direction between postoperative screws and preoperative simulated screws were compared in the observation group.ResultsAll the operation was successfully completed, and all patients were followed up 6-18 months (mean, 14.4 months). In the control group, 1 case had wound infection and 2 cases had deep vein thrombosis. No serious complication such as important blood vessels, and nerve injury and pulmonary embolism occurred in other patients in the two groups. No screw pulling out or steel plate breaking occurred. The operation time, intraoperative blood loss, fluoroscopy times, incision length, and waiting time for weight-bearing exercise of the control group were significantly more than those of the observation group (P<0.05); there was no significant difference in fracture healing time between the two groups (t=0.12, P=0.90). There was no significant difference in reduction quality between the two groups at immediate after operation (Z=–1.05, P=0.30); Majeed score of the observation group was significantly better than that of the control group at last follow-up (Z=–2.42, P=0.02). The success rate of sacroiliac joint screw implantation in the observation group reached category Ⅰ. In the observation group, the deviation angle of the direction of the screw path between the postoperative screw and the preoperative simulated screw implant was (0.09±0.22)°, and the deviation values of the entry points on the X, Y, and Z axes were (0.13±0.63), (0.14±0.58), (0.15±0.53) mm, respectively. There was no significant difference when compared with those before the operation (all values were 0) (P>0.05).ConclusionComputer design combined with 3D printing technology to make personalized pelvic model and navigation template applied to unstable pelvic fractures, is helpful to accurately place sacroiliac screw, reduce the operation time, intraoperative blood loss, and the fluoroscopy times, has good waiting time for weight-bearing exercise and function, and it is an optional surgical treatment for unstable fractures.

  • The application of percutaneous retrograde pubic screw implantation assisted by hollow pedicle opener in treatment of pubic branch fracture

    ObjectiveTo evaluate the effectiveness of percutaneous retrograde pubic screw implantation assisted by hollow pedicle opener in pubic branch fractures.MethodsThe clinical data of 42 patients with pubic branch fractures treated by hollow screw fixation between March 2008 and March 2019 were analyzed retrospectively. According to the operation method, they were divided into the traditional operation group (20 cases in group A, fixed with traditional retrograde pubic screws) and the modified operation group (22 cases in group B, fixed with percutaneous retrograde pubic screws assisted by hollow pedicle opener). There was no significant difference (P>0.05) between the two groups in terms of gender, age, cause of injury, fracture classification, comorbidity, and time from injury to operation. The operation time, blood loss, incision length, screw length, and complications were recorded and compared between the two groups. The fracture reduction was evaluated according to Matta standard on the next day after operation, and the function was evaluated by Majeed score at 12 months after operation.ResultsThe operation was successfully completed in both groups. The operation time, blood loss, and incision length of group B were significantly less than those of group A (P<0.05); there was no significant difference in screw length between the two groups (t=0.793, P=0.437). All patients were followed up 8-24 months, with an average of 16.8 months. There was no complication in the two groups, such as injury of blood vessels and nerves, fracture of internal fixation, screw entering into joint cavity, and nonunion of fracture. There was no significant difference in the fracture healing time between the two groups (t=−1.068, P=0.299). There were 2 cases of incision infection, 1 case of incision fat liquefaction, 2 cases of lower extremity deep vein thrombosis in group A, the incidence of complications was 25.0%; there was only 1 case of lower extremity deep vein thrombosis in group B, the incidence of complication was 4.5%, which was lower than that in group A, but the difference was not significant (χ2=2.104, P=0.147). In group A, 1 case was found to be dislocated, but in group B, there was no dislocated fracture. There was no significant difference between the two groups in the evaluation of Matta imaging on the next day after operation and the evaluation of Majeed function at 12 months after operation (P>0.05).ConclusionPercutaneous retrograde pubic screw implantation assisted by hollow pedicle opener is effect for the pubic branch fractures with the advantage of smaller incision, shorter operation time, and less bleeding compared with traditional methods.
