RESUMO
OBJECTIVE: To assess the clinical efficacy of minimally invasive technology with trajectory screw fixation for fragility fractures of pelvic(FFP). METHODS: A retrospective case control study was performed to analyze the clinical data of 35 patients with FFP who were treated and followed up between January 2016 and December 2019. There were 12 males and 23 females, aged from 65 to 99 years with an average of(75.4±7.8) years old. There were 13 cases of type â ¡b, 7 cases of type â ¡c, 8 cases of type â ¢a, 2 cases of type â ¢b, 2 cases of type â ¢c, 1 case of type â £b, and 2 cases of type â £c according to Rommens FFP comprehensive classification. All patients received the treatment of minimally invasive technology with trajectory screws fixation. According to the different methods of anterior pelvic ring fixation, FFP patients were divided into two groups:12 cases were fixed with the pedicle screw rod system in the anterior pelvic subcutaneous internal fixator (INFIX) group;23 cases were fixed with hollow screws of the pubic symphysis, superior ramus of pubis or acetabular anterior column in the screw group. The operation time, intraoperative blood loss, intraoperative fluoroscopy times, length of hospital stay, cost of internal fixation, pre- and post-operative visual analogue scale(VAS) were compared between the two groups. The fracture reduction quality was evaluated according to the Matta criteria, and the clinical function was evaluated by the Majeed functional scoring system respectively. RESULTS: All patients were followed up for 12 to 39(16.5±5.4) months after surgery. There was no statistically significant difference in the operation time, intraoperative blood loss, intraoperative fluoroscopy time, and length of hospital stay between the two groups(P>0.05). As for the cost of internal fixation, the cost of internal fixation in the screw group [2 914 (2 914, 4 371) yuan] was significantly lower than that of the INFIX group [6 205 (6 205, 6 205) yuan] (P<0.05). No significant difference was observed in the incidence of postoperative complications between the two groups (P>0.05). There was no significant difference in VAS assessment at admission, 1 week, and 3 months after surgery between the two groups(P>0.05). However, the VAS assessment at 1 week and 3 months after surgery of the two groups were significantly better than those at admission(P<0.05). There was no significant difference in the quality of fracture reduction after the operation and the efficacy evaluation at the last follow-up between the two groups(P>0.05). CONCLUSION: For the treatment of fragility fractures, minimally invasive technology with trajectory screw fixation can achieve good clinical efficacy. It has the advantages of being relatively minimally invasive, less bleeding, relieving the pain. It deserves clinical application.

OBJECTIVE: To evaluate the efficacy of iliolumbar fixation in the treatment of U-shaped sacral fractures. METHODS: A retrospective study was conducted on the 14 complex U-shaped sacral fractures which had been treated from January 2014 to December 2019, involved 10 males and 4 females, aged 24 to 48 (35.4±6.5) years. Fracture healing time, nerve function, clinical function and complications were observed in the patients. RESULTS: All patients were followed up for 9 to 16(26.0±5.9) months. The complete weight-bearing time for bone healing was(12.4±2.0) weeks. One case of surgical incision infection occurred after operation, and one case of sacrum nailspenetrated to the outer plate of sacrum. No complications such as pressure ulcers, loosening or rupture of internal fixation occurred. According to Gibbons scoring, the neurological function recovered from preoperative 2.9±0.9 to postoperative 2.1±1.1, there were statistically significant differences between preoperative and postoperative (t=6.9, P=0.00). There was significant difference between preoperative malformation angle (41.4±11.2)° and postoperative value (28.3±7.5)° (t=4.70, P=0.00). According to Majeed scoring to evaluate the clinical function, postoperative pain, standing, sitting, sexual life, work ability, total score respectively were 23.21±3.17, 25.57± 3.94, 7.71±1.54, 2.64±0.92, 16.14±2.41, 75.30±8.10, 2 cases got excellent results, 10 good, 2 fair. CONCLUSION: Sacral lumbar fixation is an effective method for the treatment of U-shaped sacrum fractures. It has the advantages of strong internal fixation and satisfactory functional recovery.

OBJECTIVE: To compare the clinical efficacy of three minimally invasive methods of anterior column screw, plate and screw rod system in the treatment of anterior pelvic ring fracture. METHODS: From December 2015 to September 2018, 77 patients with pelvic anterior ring fracture were treated and followed up, including 45 males and 32 females, aged 19 to 73 years. According to AO / OTA classification, there were 26 cases of type B1, 20 cases of type B2, 17 cases of type B3 and 14 cases of type C. According to the different internal fixation methods, they were divided into three groups:anterior column screw group(35 cases), plate group(20 cases), and screw rod system group(22 cases). The operation time, intraoperative fluoroscopy times, blood loss, fracture reduction quality, complications and curative effect of the three groups were compared. RESULTS: All 77 patients were followed up for 12 to 33 (16.5±5.7) months. The operation time, intraoperative blood loss and incision length of anterior column screw group were significantly shorter than those of plate group and screw rod system group, and intraoperative fluoroscopy times of plate group were significantly less than those of anterior column screw group and screw rod system group (P<0.05). There was no significant difference in the quality of fracture reduction and curative effect among the three groups(P>0.05). The incidence of complications was significant different among three group(P<0.05). CONCLUSION: Minimally invasive internal fixation with anterior column screw, plate and screw rod system can obtain good clinical effect, but anterior column screw fixation has less trauma and lower incidence of surgicalcomplications.

OBJECTIVE: To compare the complications and clinical outcome of titanium elastic nail(TEN) versus K-wire fixation(KW) for the treatment of displaced radial neck fractures in children. METHODS: From January 2009 to December 2014, 56 children with displaced radial neck fractures were studied retrospectively according to the inclusion criteria. Based on the different methods of internal fixation, patients were divided into two groups: titanium elastic nail (TEN group) and K-wire fixation (KW group). Among 25 patients(15 males and 11 females, aged from 3 to 12 years old with an average of 8.6±2.1) treated with TEN, 16 patients had type III fractures, 19 patients had type IV fractures according to Metaizeau-Judet modified classification; 20 patients were treated with closed reduction and 5 patients were treated with open reduction; the time from injury to treatment ranged from 1 to 8 days with an average of (3.6±1.7) days. Among 31 patients (20 males and 11 females, aged from 3 to 11 years old with an average of 9.1±1.9 years old) treated with KW, 19 patients had type III fractures, 12 patients had type IV fractures; 22 patients were treated with closed reduction, and 9 patients were treated with open reduction; the time from injury to treatment ranged from 2 to 7 days with an average of (3.7±1.5) days. No significant differences between two groups were found in general data. Operative time, hospitalization time, healing time of fracture, internal fixation time, postoperative complications and function recovery of the two groups were compared and evaluated. RESULTS: The average follow-up period of the patients was 22.1 months in TEN group(ranged, 16 to 48 months), and 21.9 months in KW group(ranged, 13 to 48 months). There were no significant differences between these 2 groups in follow-up duration, average hospitalization time and fracture healing time. The operation time, hospital costs and internal fixation time in TEN group were (56.6±11.8) min, (18 000±3 000) Yuan(RMB), (9.1±2.5) weeks respectively; and in KW group were(45.5±10.3) min, (8 000±1 000) Yuan(RMB), (4.8±1.6) weeks respectively, there were significant differences between two groups(P<0.05). Outcome scores according to Metaizeau and Tibone-Stoltz had no significant differences between two groups(P>0.05). CONCLUSIONS: There is no significant difference of therapeutic effects between TEN and KW for children with displaced radial neck fractures. Because the removal of TEN fixation requires the secondary anesthesia, and the TEN costs significantly more than KW, TEN still can't replace the traditional KW for the treatment of radial neck fracture in children.
