A Case of "Nonunion Distal Tibia and Fibula Malleoli Fracture with posterior Malleoli Fracture" Treated with Ilizarov: A Case Report.

Introduction: Orthopedic surgeons have long acknowledged the difficulty of treating distal tibia and fibula fractures with posterior malleoli fractures in individuals with medical comorbidities due to a lack of inadequate blood supply. Aged Type 2 diabetic individuals, with distal tibia and fibula fracture with posterior malleoli fracture, are more prone to complications such as non-union, wound infection, and delayed bone healing. It is debatable whether surgical or non-invasive treatment is preferable for diabetic complex fractures. Case Report: A 62-year-old male suffered a right distal tibia and fibula fracture with posterior malleoli fracture following an incidental fall followed by a hit over the iron rod. The patient was treated conservatively with POP for 6 weeks due to the patient's refusal of surgical management. Radiography after 6 weeks revealed features of non-union. Conclusion: The Ilizarov external fixation with bone graft was planned later to treat the non-union distal tibia and fibula fracture with posterior malleoli fracture. About 18 months after the Ilizarov fixation radiography reviewed the features of the union and clinically also patient improved.

[Comparative study of the effects of intramedullary nail fixation and minimally invasive percutaneous plate internal fixation technique on platelet activation and serum transforming growth factor-ß1(TGF-ß) 1 and bone morphogenetic protein-2 (BMP-2) in patients with tibial and fibular fracture].

OBJECTIVE: To investigate the effect of intramedullary nail fixation (IMN) and minimally invasive percutaneous plate internal fixation (MIPPO) techniques on tibiofibular fractures and their effect on platelet activation and serum transforming growth factor-ß1 (TGF-ß1) and bone morphogenetic protein-2 (BMP-2). METHODS: Total of 105 patients with tibiofibular fractures from February 2019 to February 2020 were selected and divided into 53 cases in the MIPPO group and 52 cases in the IMN group. There were 29 males and 24 females with an average age of (41.74±6.05) years old in MIPPO group;in IMN group, 31 males and 21 females with an average age of (40.59±5.26) years old. The perioperative surgical indexes, postoperative complications, ankle function recovery at 12 months postoperatively, platelet activation indexes at 3 and 7 days preoperatively and postoperatively, and serum TGF-ß1 and BMP-2 levels at 4 and 8 weeks preoperatively and postoperatively were compared between the two groups. RESULTS: The operating time and fracture healing time in the MIPPO group were shorter than those in the IMN group(P<0.05); Compared with the preoperative period, the levels of GMP-140, PAC-1, CD63, and CD61 increased in both groups at 3 and 7 days after surgery, but were lower in the MIPPO group than in the IMN group(P<0.05);the levels of serum TGF-ß1 and BMP-2 increased in both groups at 4 and 8 weeks after surgery compared with the preoperative period, and the postoperative complication rate in the MIPPO group was lower than that in the IMN group(P<0.05);the difference was not statistically significant in the excellent rate of ankle function recovery at 12 months follow-up after surgery between two groups(P>0.05). CONCLUSION: Both intramedullary nail fixation and MIPO technique for treatment of tibia and fibula fractures can improve ankle joint function, but the latter has the advantages of short operation time, fast fracture healing, fewer complications, and light platelet activation. Serum TGF-ß1, BMP-2 level improves quickly.

Clinical analysis of accelerated rehabilitation surgery for Gustilo type IIIA/B open tibio fibular fracture.

PURPOSE: To investigate the clinical efficacy of accelerated rehabilitation surgery for the treatment of Gustilo type IIIA/B open tibiofibular fracture with emergency stage I debridement, internal fracture fixation, bone grafting, coverage of the wound surface with a muscle flap combined with vacuum sealing drainage (VSD), and internal and lateral leg reduction. METHODS: A retrospective analysis was performed on the clinical data of 15 patients with Gustilo type IIIA/B open tibiofibular fracture who were admitted to the Affiliated Zhongshan Hospital of Dalian University from January 2015 to December 2018. There were 12 males and 3 females. The patients ranged in age from 20 to 62 years, with an average of 39.5 years. After admission, the patients underwent stage I emergency debridement (including exploration and repair of nerves and tendons), open reduction and internal fixation of the tibia and fibula, iliac bone grafting, muscle flap and VSD coverage of the bone defect, complete tensioning of the calf inside and outside, tibia-sparing incision before healing, and stage II free skin grafting. Patients were followed up periodically to observe muscle flap survival, fracture healing time, length of hospitalization, wound healing time, delayed union, bone nonunion, osteomyelitis and other complications. At the last follow-up, the Johner-Wruhs criteria were used to evaluate the rate of good functional recovery from tibial shaft fracture, fracture healing quality was evaluated by the Merchant score, and limb function was evaluated by the LEFS. RESULTS: All 15 cases were followed up for 12-32 months, with an average of 22.8 months. All the fractures healed; the range of healing time was 14-30 weeks (mean 18.5 weeks). The length of hospitalization was 25.1 ± 7.6 days, and wound healing took 12.2 ± 2.0 days. None of the patients had complications such as osteomyelitis infection. When the Johner-Wruhs evaluation criteria for functional recovery from tibial shaft fracture were applied at the last follow-up, the outcomes were as follows: excellent in 13 cases, good in 1 case and fair in 1 case, for an excellent and good rate of 93.3%. When fracture healing was evaluated according to the Merchant scoring standard, the outcomes were as follows: excellent in 12 cases, good in 1 case, fair in 1 case, and poor in 1 case, for an excellent and good rate of 86.7%. The mean LEFS score of the affected limb at the last follow-up was 70 (59-80). CONCLUSION: For Gustilo type IIIA/B open tibiofibular fractures, emergency stage I debridement, internal fixation of the fracture, bone grafting, coverage of the wound with a muscle flap, complete tensioning of the calf inside and outside, and application of VSD can improve the repair of leg soft-tissue defects, shorten hospitalization time, promote fracture healing, and effectively reduce infection and complications related to bone exposure. More importantly, this treatment protocol provides effective wound repair, guarantees the recovery of limb function, significantly speeds up recovery, and improve patients' quality of life.

Etiological spectrum and treatment outcome of wound infection in patients with open tibia and fibula fractures.

OBJECTIVE: To explore the etiology of wound infections in patients with open tibia and fibula fractures and the treatment effects. METHODS: In this retrospective study, a total of 76 patients with open tibia and fibula fractures were included in this research. These patients were divided into the control group (n=38) and the observation group (n=38) according to the treatment methods for wound infection. The distribution and drug resistance of pathogenic bacteria in wound infections were analyzed. Clinical effects, time for body temperature returning to normal, time for disappearance of exudates, time for clearance of pathogenic bacteria, recovery effects and patients' satisfaction rate were also compared between two groups. RESULTS: A total of 152 strains of pathogenic bacteria were separated. The main pathogenic bacterium was Acinetobacter baumannii, accounting for 30.92% (47/152). Pathogenic bacteria were demonstrated to be highly sensitive to vancomycin and imipenem. The proportion of wound healing by first intention and the Johner-Wruhs scores in observation group were significantly higher than those in control group, while recurrent infection rate, the time to restore normal body temperature, the time for exudates to disappear, the time to remove pathogenic bacteria, hospital stays and VAS scores in observation group were obviously shorter or lower than those in control group (all P<0.05). Moreover, the satisfaction rate of patients in the observation group was significantly higher than that in the control group (P<0.05). CONCLUSION: Understanding pathogenic characteristics and drug resistance of wound infection in patients with open tibia and fibula fractures is helpful to subsequent treatment. Comprehensive control measures should be taken to decrease incidence of wound infection.

The effectiveness of a self-made modular elastic compression device for patients with a fracture of the tibia and fibula.

BACKGROUND: To evaluate the effectiveness of a self-made modular elastic compression device for patients with a fracture of the tibia and fibula. METHODS: Fifty-nine healthy adult patients with a unilateral fracture of the tibia and fibula were randomly divided into an experimental group and a control group. The experimental group was given the self-made combined elastic compression device for the compression treatment of the affected limbs after the operation. The main endpoints included the convenience, safety, and effectiveness of the self-made modular elastic compression device for patients with a fracture of the tibia and fibula. RESULTS: There were 29 cases in the experimental group and 30 cases in the control group. There were no significant differences between the two groups in the general data: age, gender, fracture site, and cause of injury. The preoperative swelling elimination time was 3.3 ± 1.2 days, and the postoperative swelling elimination time was 3.1 ± 1.4 days in the experimental group; the preoperative swelling elimination time was 6.3 ± 1.2 days, and the postoperative swelling elimination time was 7.3 ± 1.2 days in the control group. The preoperative and postoperative swelling degree in the experimental group was shorter than those in the control group. The difference in the postoperative detumescence time between the experimental group (3.1 ± 1.4 days) and the control group (7.3 ± 1.2 days) was significant, and the total hospital stay was 8.1 ± 1.5 days in the experimental group and 13 ± 2.5 days in the control group with a statistical significance of P < 0.05. The change of discharge hemoglobin volume (11.2 ± 6.5 g/L) of the experimental group was lower than that of the control group (3.5 ± 1.2 days), the total drainage volume was 260 ± 50 ml, and the change of admission and discharge hemoglobin volume was 30.3 ± 10.4 g/L. Specifically, although the difference in the average hospital stay between the two groups was statistically significant, the difference was only 1 day, and the clinical difference was not significant. However, in the change of the cumulative drainage volume and hemoglobin volume, the experimental group that was given compression therapy was significantly lower than the control group with a statistical significance (P < 0.05). The pressure injury (4 cases) in the experimental group was significantly lower than that in the control group (8 cases) (P < 0.05). CONCLUSION: A modular combined elastic compression device in patients with a tibial and fibular fracture can significantly accelerate a patient's rehabilitation, shorten the hospital stay, reduce blood loss, relieve the patient's pain, and relieve the patient's social-economic burden during recovery.

[The dynamization of external fixation for treatment of open tibia and fibula fractures].

Objective: To evaluate the effects of dynamization of external fixation on open tibia and fibula fracture union. Methods: The clinical data of 26 cases of open tibia and fibula fractures treated by external fixation were retrospectively analysed. According to different postoperative treatment methods, the patients were divided into elastic dynamic group (group A, n=13) and constant elastic fixation group (group B, n=13). There was no significant difference in gender, age, and fracture type between 2 groups ( P>0.05). The removal time of external fixator in group B was evaluated by fracture healing time, X-ray film, and doctor's experience. In group A, the growth of callus was examined based on X-ray film at 12 weeks after operation; the axial mechanical load ratio was tested, and dynamic loading was carried out when the axial mechanical load ratio was 5%-10%. The using time of external fixator, fracture healing time, and incidence of complications were compared between 2 groups. Results: All patients were followed up 4-13 months, with an average of 5.7 months. During the treatment, there was no complication such as loosening or breaking of the external fixator, fracture displacement, or re-fracture in 2 groups. The using time of external fixator in group A was (24.77±1.42) weeks and the fracture healing time was (23.04±1.30) weeks, which were all significantly reduced when compared with those in group B [(34.38±1.71) weeks and (32.46±1.66) weeks] ( t=16.10, P=0.00; t=15.58, P=0.00). In group A, there were 2 cases of needle tract infection and 1 case of muscle weakness, the incidence of complication was 23.1%; in group B, there were 3 cases of needle tract infection, 1 case of muscle weakness, and 1 case of delayed union of fracture, the incidence of complication was 38.5%; there was no significant difference in the incidence of complication between 2 groups ( P=1.000). Conclusion: Dynamization of external fixation can promote union of open tibia and fibula fractures with a high security.

Analysis of a generic talar prosthetic with a biological talus: A cadaver study.

Treatment for talar avascular necrosis is challenging. This study evaluates the feasibility of a generic talar implant by cadaveric assessment. Ten cadaveric ankles were CT-scanned to determine talar implant size. The opposite ankles were CT-scanned with the biological talus and then with the implant. 3D ankle geometry was reconstructed and implant position was compared to the biological talus position. The averages among specimens' positive and negative average-deviations were 0.91 mm and 0.70 mm. Seventy percent of talar dome deviations between the biological talus and implant were within an acceptable range. This study yields promising results to support a generic talus bone prosthetic.

Autologous platelet lysates local injections for treatment of tibia non-union with breakage of the nickelclad: a case report.

BACKGROUND: Nonunions of the tibia represent challenging orthopedic problems, which require the surgeon to analyze numerous factors and choose an appropriate treatment. This article presents a case report of tibia and fibula fracture patient who failed the internal fixation surgery and successfully recovered after one course of percutaneous autologous platelet lysates injection. CASE DESCRIPTION: The patient received an internal nickelclad breakage at 9 months post-surgery but reluctant to accept a second surgery, then autologous platelet lysates (APL) injection which is a less invasive method was recommended. The injections were carried once a week for three times. Radiologic evaluation was conducted every month until recovery. DISCUSSION AND EVALUATION: To the best of our knowledge, this is the first reported case of tibia delayed union with breakage of the plate resolved with APL injection. Improved clinical evidence was observed at 4 and 6 months after injection. The patient got good bony union at 8 months post-injection. The patient didn't feel any discomfort postinjection, no complications such as infection, refracture etc. were observed. CONCLUSIONS: APL percutaneous injection could be a new therapeutic option for the treatment of nonunion or delayed healing fractures.

[CLINICAL APPLICATION OF AXIAL LOAD MECHANICAL TESTING IN REMOVING EXTERNAL FIXATOR AFTER TIBIA AND FIBULA FRACTURES SURGERY].

OBJECTIVE: To explore the efficacy and safety of the axial load mechanical testing for removing external fixator. METHODS: Between January 2014 and August 2015, 27 patients with tibia and fibula fractures caused by trauma underwent an external fixation. Of 27 patients, 21 were male and 6 were female with the average age of 45 years (range, 19-63 years), including 7 cases of closed fracture and 20 cases of open fracture. X-ray film results showed spiral unstable fracture in 4 cases and comminuted unstable fracture in 23 cases. All patients underwent an external fixation. Bone nonunion occurred in 3 cases because of infection, and bone nonunion combined with bone defect occurred in 1 case, who received tibial osteotomy lengthening surgery. When X-ray film showed continuity high density callus formation at fracture site, axial load mechanical test was performed. If the axial load ratio of external fixator was less than 10%, the external fixator was removed. RESULTS: At 21-85 weeks after external fixation (mean, 44 weeks), axial load mechanical test was performed. The results showed that the axial load ratio of external fixation was less than 10% in 26 cases, and the external fixator was removed; at 6 weeks after removal of external fixator, the patients could endure full load and return to work, without re-fracture. The axial load ratio was 14% in 1 case at 85 weeks, and the X-ray film result showed that fracture did not completely heal with angular deformity; re-fracture occurred after removing external fixator, and intramedullary fixation was used. CONCLUSIONS: External fixator axial load mechanical testing may objectively reveal and quantitatively evaluate fracture healing, so it is safe and reliable to use for guiding the external fixator removal.

Clinical analysis of the rap stress stimulator applied for crus fracture after skeletal external fixation.

INTRODUCTION: Open crus fracture is still difficult in clinical treatment because of the delayed fracture union and high rate of nonunion after the operation. A consensus has been reached that mechanical stress can promote fracture healing. We independently developed a stress stimulator, which can provide longitudinal pressure for the fixed fracture end of the lower legs to promote fracture healing. The purpose of this study is to explore the advantages and clinical effect of the rap stress stimulator applied for open crus fracture after skeletal external fixation. MATERIAL AND METHODS: One hundred and sixty-five patients (183 limbs) who suffered from open tibia and fibula fracture received skeletal external fixation, of which 108 limbs were treated with the rap stress stimulator after external fixation and 75 limbs were treated with regular functional exercises of muscle contraction and joint activity only. Then the fracture healing time and rate of nonunion were compared between the two groups. RESULTS: The mean fracture healing time and rate of nonunion in the group treated with the rap stress stimulator were 138.27 ±4.45 days and 3.70% respectively, compared to 153.43 ±4.89 days and 10.67% in the group treated without the stimulator. CONCLUSIONS: The rap stress stimulator significantly shortened the fracture healing time and reduced the rate of nonunion for treating open tibia and fibula fractures.
