Single stage management of Gustilo type III A/B tibia fractures: Fixed with nail & covered with fasciocutaneous flap

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.

Study on the relationship between the timing of conversion from external fixation to internal fixation and infection in the treatment of open fractures of extremities

Objective

To investigate the relationship between the infection rate and the timing of replacement of temporary external fixators with internal fixation, and the timing of immediate or delayed internal fixation after removal of temporary external fixation in the staging treatment modality of open fractures of extremities.

Methods

A retrospective analysis was performed on 122 cases of open fractures of extremities. External fixators were applied at the early stage and replaced with internal fixation when the condition of soft tissues improved and inflammatory indexes dropped to the normal range or showed a steady downward trend. Depending on the carrying time of external fixators after wound closure or healing, the patients were divided into three groups; the carrying time of groups A, B, and C was ≤ 14 days, 15–28 days, and > 28 days, respectively. Depending on the immediate or delayed internal fixation after removal of external fixator, patients were divided into group a (immediate internal fixation after removal of external fixator) and group b (delayed internal fixation after removal of external fixator, 5–7 days later).

Results

The infection rates of groups A, B, and C were 6.5%, 5.9%, and 23.3%, respectively. The differences among the three groups were statistically significant (P < 0.05). The infection rates of different Gustilo–Anderson fractures were as follows: no cases of infection out of 10 cases with type I fracture (0%); two cases of infection out of 35 cases with type II fracture (5.7%); three cases of infection out of 36 cases with IIIa fracture (8.3%); five cases of infection out of 28 cases with IIIB fracture (17.9%); and five cases of infection out of 13 cases with IIIC fracture (38.5%). The differences among the five groups were statistically significant.

Conclusions

The occurrence of infection of open fractures of extremities is associated with the fracture severity (Gustilo classification). For open fractures of Gustilo types I and II, the final internal fixation should be placed as soon as possible when the recovery of general and local conditions is good and the infection is controlled.

Tibial Nail Combined with Vacuum Sealing Drainage for Gustilo Grade IIIB Open Tibial Fractures: A Patient Series

Gustilo grade IIIB open tibial fractures are relatively difficult to treat. We investigated the treatment effects of tibial intramedullary nails combined with vacuum sealing drainage (VSD) for Gustilo grade IIIB open tibial fractures. From March 2015 to March 2017, 13 cases of Gustilo grade IIIB open tibial fractures were treated with Expert Tibial Nails combined with VSD. Causes of injury included falls from a height (n = 9, 69.2%) and road accidents (n = 4, 30.8%). The duration from time of injury to hospital intake was 7.3 hours (range 5 to 9.5), and the time between injury and operation was 6.7 days (range 3 to 11). Six months after the operation, overall patient general health was investigated via the American Orthopaedic Foot and Ankle Society (AOFAS) ankle score and the physical and mental health dimensions of the Short-Form Health Survey 36 (SF-36). Postoperative complications and infections also were recorded. The results indicated that the median AOFAS score was 93.7 (range 89 to 97), with all individuals having either excellent (90 to 100; n = 10, 76.9%) or good (80 to 89; n = 3, 23.1%) outcomes. The median physical SF-36 score was 83.1 (range 72.5 to 93.0), and the median mental SF-36 score was 80.6 (range 69.7 to 92.0). Moreover, there were no instances of tibial shortening, neurovascular injury, postoperative complications, implant failure, malunion, or serious infections. In conclusion, intramedullary tibial nail combined with VSD is a safe and effective method to treat type grade IIIB open tibial fractures.

Soft tissue management in open tibial shaft fractures: A comparison of institutional preferences and resultant early clinical outcomes

Aims

To compare results of institutional preferences with regard to treatment of soft tissues in the setting of open tibial shaft fractures.

Methods

We present a retrospective review of open tibial shaft fractures at two high-volume level 1 trauma centres with differing practices with regard to the acute management of soft tissues. Site 1 attempts acute primary closure, while site 2 prefers delayed closure/coverage. Comparisons include percentage of primary closure, number of surgical procedures until definitive closure, percentage requiring soft tissue coverage, and percentage of 90-day wound complication.

Results

Overall, there were 219 patients at site 1 and 282 patients at site 2. Differences in rates of acute wound closure were seen (168 (78%) at site 1 vs 101 (36%) at site 2). A mean of 1.5 procedures for definitive closure was seen at site 1 compared to 3.4 at site 2. No differences were seen in complication, nonunion, or amputation rates. Similar results were seen in a sub-analysis of type III injuries.

Conclusion

Comparing outcomes of open tibial shaft fractures at two institutions with different rates initial wound management, no differences were seen in 90-day wound complications, nonunion rates, or need for amputation. Attempted acute closure resulted in a lower number of planned secondary procedures when compared with planned delayed closure. Providers should consider either acute closure or delayed coverage based on the injury characteristics, surgeon preference and institutional resources without concern that the decision at the time of index surgery will lead to an increased risk of complication.

Concurrent internal fixation and soft tissue reconstruction by distally based sural flap: a practicable scheme for complex distal tibial fractures

BACKGROUND

It is difficult to establish both fracture union and wound healing of open fractures complicated with soft tissue defects of the distal tibia. We describe the simultaneous use of internal fixation and soft tissue coverage by a distally based sural flap (DBSF) for these complex injuries.

METHODS

Seventeen patients with Gustilo IIIB open fractures of the distal tibia were operated on by internal fixation and DBSF coverage. Data were collected on the size of the defect, time to fixation and soft tissue coverage or 'fix & flap', types of implant, time to union, postoperative complications and objective clinical measurement.

RESULTS

The average size of the soft tissue defect after debridement was 6.4 × 8.4 cm² (range 4.0-9.0 × 6.0-12.0). The mean time to fix & flap was 8.1 days (range 7-10). A medial precontoured plate was used in 8 patients and an anterolateral precontoured plate in 9. All fractures were united in a mean duration of 22.6 weeks (range 20-28). One patient had partial flap necrosis. Using the Puno functional score, 2 patients had excellent functional outcomes and 15 patients had good functional outcomes.

CONCLUSION

Concurrent Internal fixation and soft tissue reconstruction by DBSF is effective and reproducible for Gustilo type III open fractures of the distal tibia even in cases of more than 50 cm² soft tissue defects.

Clinical outcome of conversion from external fixation to definitive internal fixation for open fracture of the lower limb

INTRODUCTION

Few reports have examined the outcomes and complications of temporary bridging external fixation (EF) in open fracture of the lower limb followed by conversion to open reduction internal fixation (ORIF). The purpose of this study was to evaluate healing rates and complications in patients treated with conversion from external fixation to definitive internal fixation for open fracture of the lower limb.

METHOD

Patients who underwent temporary bridging EF and subsequent conversion to internal fixation (IF) for open fracture of the lower limb, with follow-up period ≥12 months were included in this study. Demographic data, Gustilo-Anderson classification, fracture type, duration to definitive surgery, surgical procedure, perioperative complications, and additional procedures for cases with complications were obtained.

RESULTS

In total, 58 patients (43 males, 15 females), 63 fractures were included in this study. Four fractures (6.3%) were Gustilo grade I, 11 fractures (17.5%) were grade II, 34 fractures (54.0%) were grade IIIa, 12 fractures (19.0%) were grade IIIb, and two fractures (3.2%) were grade IIIc. Mean duration of the application of EF was 12.4 days (range, 3-45 days) until conversion to definitive IF. Rates of deep infection and nonunion were both 9.5%, with two cases showing concomitant infection and nonunion. Rates of infection were 8.8% (3/34) in grade IIIa and 25% (3/12) in grade IIIb. Rates of nonunion were 9.1% (1/11) in grade II, 2.9% (1/34) in grade IIIa and 33% (4/12) in grade IIIb.

CONCLUSION

Temporary EF for open fracture of the lower limb followed by conversion to IF, as early as soft tissue and general condition permit, may be a safe and effective procedure for patients with lower-limb open fracture of Gustilo grade IIIa or less.
