A Comparative Analysis of Between Percutaneous Cannulated Screw Fixation and Traditional Plate Internal Fixation in Treatment of Sanders II and III Calcaneal Fractures

The objective of this study is to compare the clinical efficacy of percutaneous cannulated screw fixation and traditional plate internal fixation in the treatment of Sanders II and III calcaneal fractures. The records of 64 patients were retrospectively analyzed. Thirty-three cases were fixed by percutaneous cannulated screws. Thirty-one cases were fixed with traditional steel plates. The preoperative preparation time of the screw group and plate group was 3 ± 1.7 days and 4.6 ± 2.1 days. The surgery time was 118.9 ± 43.8 minutes and 146.9 ± 47.6 minutes. The length of hospitalization was 8.7 ± 3.9 days and 17.0 ± 7.9 days. Intraoperative blood loss was 38.2 ± 27.7 mL and 67.1 ± 58.8 mL. The postoperative drainage volume of the plate group was 85.1 ± 53.7 mL, and no wound drainage was needed in the screw group after surgery. Postoperative wound complications occurred in 2 cases of the screw group and 8 cases of the plate group. The recovery effects of Gissane angle and Bohler angle are similar in the 2 groups. The excellent and good rate of the American Orthopaedic Foot and Ankle Society ankle-hindfoot Scale in the screw group was 96.8% at 12 months after surgery, whereas the rate was 93.5% in the plate group. Compared with the traditional plate internal fixation, the percutaneous cannulated screw group achieved a similar excellent and good rate of clinical treatment. It has the advantages of less trauma, less bleeding, low incidence of complications, short preoperative preparation, and hospitalization time.

Comparison of effectiveness of anterior subcutaneous internal fixator and plate internal fixation for unstable anterior pelvic ring fractures

To compare the effectiveness of anterior subcutaneous pelvic internal fixator (INFIX) and plate internal fixation in treatment of unstable anterior pelvic ring fractures. The clinical data of 48 patients with unstable anterior pelvic ring fractures who met the selection criteria between June 2014 and December 2019 were retrospectively analyzed. Among them, 21 cases were treated with INFIX (INFIX group), and 27 cases were treated with plate (plate group). There was no significant difference in gender, age, body mass index, cause of injury, time from injury to operation, Injury Severity Score (ISS), and fracture type between the two groups ( P>0.05). The operation time, intraoperative blood loss, fracture healing time, partial weight-bearing time, and complete weight-bearing time were recorded and compared between the two groups. Matta standard was used to evaluate the quality of fracture reduction, and Majeed score system was used to evaluate the functional recovery of pelvic fracture after operation. The patients in both groups were followed up for an average of 12.5 months (range, 6-16 months). The operation time and intraoperative blood loss in INFIX group were significantly lower than those in plate group ( t=-11.965, P=0.000; t=-20.105, P=0.000). There was no significant difference in the quality of fracture reduction, fracture healing time, partial weight-bearing time, and complete weight-bearing time between the two groups ( P>0.05). At 14 weeks after operation, there was no significant difference in the scores of pain, working, standing and walking, and total scores between INFIX group and plate group ( P>0.05), but there were significant differences in sitting and sexual intercourse scores ( t=-4.250, P=0.003; t=-6.135, P=0.006). The incidences of lateral femoral cutaneous nerve injury, femoral nerve injury, and heterotopic ossification were significantly higher in INFIX group than in plate group ( P<0.05), while the incidence of incision infection was lower in INFIX group than in plate group ( P<0.05). Compared with the plate internal fixation, the INFIX internal fixation can obtain the similar effectiveness for the unstable anterior pelvic ring fracture and has the advantages of shorter operation time, less blood loss, and lower risk of infection.

Application of bone transport with unilateral external fixator combined with locked plate internal fixation in treatment of infected tibial nonunion

To summarize the effectiveness of bone transport with unilateral external fixator combined with locked plate internal fixation in treatment of infected tibial nonunion. Between January 2010 and December 2014, 23 patients with infected tibial nonunion were treated with bone transport with unilateral external fixator combined with locked plate internal fixation. There were 19 males and 4 females with an average age of 37.8 years (range, 19-54 years). The mean length of the bone defect was 6.5 cm (range, 5.2-8.1 cm). The number of previous operations ranged from 2 to 4 times, with an average of 2.5 times. The time from injury to this treatment was 7-23 months, with an average of 11.8 months. The time of bone transport, time of the external fixation, fracture healing time, external fixation index, healing index, and complication were recorded; and the Association for the Study and Application of the Methods of Ilizarov (ASAMI) bone healing and function scores were used to evaluate the effectiveness. All patients were followed up 3-6 years with an average of 4.8 years. Wounds and bone defects healed in all patients. No complication such as infection recurrence, nonunion, re-fracture, malunion, iatrogenic nerve paralysis, or stiffness of knee and ankle joints occurred. Five patients had needle infections which were treated by local care and no deep infection occurred. The time of bone transport was 65-120 days (mean, 75.6 days); the time of the external fixation was 75-145 days (mean, 97.8 days); the fracture healing time was 4-17 months (mean, 8.7 months); the external fixation index was 18-28 days/cm (mean, 22.4 days/cm); and the healing index was 31-52 days/cm (mean, 40.2 days/cm). At last follow-up, according to ASAMI criteria, the result of bone healing was excellent in 15 cases and good in 8 cases, and the result of function was excellent in 18 cases and good in 5 cases, all with the excellent and good rate of 100%. For infected tibial nonunion, bone transport with unilateral external fixator combined with locked plate internal fixation can reduce the time of external fixation and related complications, with a satisfactory effectiveness.

Curative effect of anatomic plate internal fixation for complex proximal humeral fractures combined with humeral shaft fractures

Objective To investigate the efficacy of anatomic plate internal fixation in treatment of complex proximal humeral fractures combined with humeral shaft fractures. Methods This retrospective case series study included 58 patients with complex proximal humeral fractures combined with humeral shaft fractures admitted from July 1998 to July 2015. There were 31 males and 27 females, with a mean age of 63 years (range, 18-86 years). According to the Neer classification of proximal humeral fractures, three-part fractures were noted in 42 patients and four-part fractures in 16 patients. Four patients were combined with compressed or splitting fractures of the head of humerus and 38 patients with dislocation of the shoulder. According to the site classification of femoral shaft fractures, proximal 1/3 shaft fractures were noted in 36 patients, middle and distal 1/3 shaft fractures in 19, and multisegmental shaft fractures in three. All patients underwent anatomic reduction and anatomic plate internal fixation. Bone healing, Neer score of function outcome and complications were evaluated after operation. Results Mean duration of follow-up was 8.6 years (range, 1-18 years). Bone union was observed in all patients after 10 to 24 weeks (mean, 14.5 weeks). According to the Neer score, the outcomes were excellent in 23 patients, good in 25, fair in eight and poor in two, with the excellent rate of 83%. Complications such as infection, nerve injury and vascular injury were not observed after operation. Six patients suffered from limitations of shoulder anterior flexion and rise, one patient had humeral head necrosis and treated by shock wave treatment, and one patient had poor incision healing with hemorrhagic effusion and cured after dressing. Conclusion Anatomic plate internal fixation can contribute to fast functional recovery and few complications in treatment of complex proximal humeral fractures combined with humeral shaft fractures.
