Outcomes after implementation of an open fracture clinical pathway

Value of negative pressure sealing drainage on wound healing of Gustilo IIIB and IIIC open fractures

BACKGROUND

Gustilo III fractures have a high incidence and are difficult to treat. Patients often experience difficulty in wound healing. Negative pressure drainage technology can help shorten wound healing time and has positive value in improving patient prognosis.

AIM

To explore the clinical value of the negative pressure sealing drainage technique in wound healing of Gustilo IIIB and IIIC open fractures.

METHODS

Eighty patients with Gustilo IIIB and IIIC open fractures with skin and soft tissue injuries who were treated in the Second People's Hospital of Dalian from March 2019 to December 2021 were selected as the research subjects. They were divided into a study group (n = 40, healed with negative pressure closed drainage) and a control group (n = 40, healed with conventional dressing changes) according to the variation in the healing they received. The efficacy of the clinical interventions, the variations in the regression indicators (time to wound healing, time to fracture healing, time to hospitalization), and the conversion and healing of bacterial wounds were compared 1-3 mo after the intervention.

RESULTS

The total effective rate of patients among the study group was 95.00% (38/40), which was notably higher than 75.00% (30/40) among the control group (P < 0.05). The wound healing time, fracture healing time, and hospital stay of the patients in the study group was shorter than the control group (P < 0.05). After the intervention, the negative bacterial culture at the wound site rate and wound healing rate of the patients among the study group increased compared to the control group (P < 0.05).

CONCLUSION

Negative pressure sealing and drainage technology has a good therapeutic effect on patients with Gustilo IIIB and IIIC open fracture wounds with skin and soft tissue injury. It can notably enhance the wound healing rate and the negative rate of bacteria on the wound surface and help to speed up the recovery process of patients.

Outcomes following surgical fixation of Gustilo-Anderson IIIb open tibial fractures

There is no consensus as to the optimal skeletal fixation method for Gustilo-Anderson IIIb fractures. External fixation methods have previously shown higher rates of superficial infection, whilst internal fixation has shown higher risk of deep infection, but lower risk of other complications. This paper investigates outcomes in open tibial fractures based on fixation method. A retrospective review was performed for patients presenting to an ortho-plastic unit with GA IIIb tibial fractures between June 2013 and October 2021. 85 patients were identified. The most common implant was an intramedullary nail (IMN), used in 29 patients (34.1%); open reduction and internal fixation (ORIF) was performed in 16 patients (18.8%). 18 patients (21.2%) were definitively managed with a frame alone. Mean follow-up from was 18 months (2-77). Patients with ORIF needed a mean of 3.37 operations; it was 2.48 for IMN which was significantly different from frames at 5.00 (p=0.000). The mean time to bony union after definitive fixation was 11.4 months. This differed depending on the implant used for fixation, with ORIF at 7.1 months, 10.1 for IMN, and frames at 17.2 months; ORIF significantly differed from frames (p=0.009). Superficial infection was common, seen in 38.8% of patients, and only 3 patients (4%) developed deep infections involving metalwork, with no difference in rates of either based on fixation method This study supports that ORIF has faster healing times, with less time to union compared to frames. It also shows that no implant was superior to another in terms of outcomes.

Clinical and Radiological Outcomes of Gustilo-Anderson Type IIIB Open Fractures in 125 Patients

INTRODUCTION

This study describes single-centre outcomes of Gustilo-Anderson type IIIB open fractures in relation to the current standards in the United Kingdom, which aim at performing skeletal fixation and soft tissue coverage at an early stage to salvage the limb and achieve bone union with a minimum infection rate.

METHODS

A total of 125 patients with 134 Gustilo-Anderson type IIIB open fractures, who had definitive skeletal fixation with soft tissue coverage between June 2013 and October 2021, were prospectively followed up and included in this study.

RESULTS

Initial debridement was performed within 12 hours from the time of injury for 62 (49.6%) patients and within 24 hours for 119 (95.2%) patients (mean= 12.4 hours). Definitive skeletal fixation and soft tissue coverage were achieved within 72 hours for 25 (20%) patients and within seven days for 71 (57%) patients (mean= 8.5 days). The mean follow-up duration was 43.3 (6-100) months, and the limb salvage rate was 97.1%. The occurrence of deep infections was associated with time from injury to initial debridement (p=0.049). Three patients (2.4%) developed deep (metalwork) infections, all three had their initial debridement performed within 12 hours from the time of injury. There was no association between time to definitive surgery and the development of deep infection (p=0.340). Bone union was achieved in 84.3% of patients following their primary surgery. Time to union was associated with fixation modality (p=0.002) and type of soft tissue coverage (p=0.028), and was negatively correlated with time to initial debridement (p=0.002, correlation coefficient -0.321). There was a 0.27-month decrease in time to union for every hour delay in time to debridement (p=0.021).

CONCLUSION

Delaying initial debridement or definitive fixation and soft tissue coverage didn't increase the rate of deep (metalwork) infections. The time to achieve bone union was negatively correlated with the time from injury to initial debridement. We advise prioritising surgical technique and availability of expertise over strict adherence to time thresholds of surgeries.

Evaluation of the orthopaedic trauma association open fracture classification (OTA-OFC) as an outcome prediction tool in open tibial shaft fractures

INTRODUCTION

It was the goal of this study to determine if the Orthopaedic Trauma Association Open Fracture Classification (OTA-OFC) correlates with complication rates and to determine if it can be used as a predictive tool in the treatment of open tibial shaft fractures.

MATERIALS AND METHODS

Retrospective review from two high-volume level 1 trauma centers of open tibial shaft fractures over a 5 year period. Variables of interest included OTA-OFC, type of wound closure, 90-day wound complication, unplanned re-operation, non-union, and amputation.

RESULTS

501 consecutive open tibial shaft fractures. 57.3% (n = 287) were closed primarily; local soft tissue advancement/rotational flap was used in 9.6% (n = 48); free soft tissue transfer used in 22.8% (n = 114); 8.6% (n = 43) required amputation. Of those followed for 90 days (n = 419), 45 (9.0%) had a wound complication, of which 40 (8%) required an unplanned reoperation. 40 (8.0%) patients went on to a documented non-union. All OTA-OFC classification groups significantly correlated with type of definitive closure (r = 0.18-0.81, p < 0.05) with OTA-OFC skin showing the strongest correlation (r = 0.81). OTA-OFC bone loss weakly correlated with wound complication (r = 0.12, p = 0.02) and no OTA-OFC classification correlated with the need for an unplanned secondary procedure. OTA-OFC skin, muscle and arterial all weakly correlated with non-union (r = 0.18-0.25, p < 0.05). OTA-OFC muscle was predictive of non-union (OR = OR = 2.2, 95% CI = 1.2-4.1) and amputation (OR 9.3, 95% CI = 3.7-23.7). OTA-OFC arterial was also predictive of amputation (OR 4.8, 95% CI = 2.5-9.3).

CONCLUSIONS

The OTA-OFC correlates variably with the type of definitive closure, the development of a 90-day wound complication, and the occurrence of a non-union. Importantly, OTA-OFC muscle classification is predictive of non-union while both OTA-OFC muscle and arterial were predictive of amputation.

One-stage combined "fix and flap" approach for complex open Gustilo-Anderson IIIB lower limbs fractures: a prospective review of 102 cases

BACKGROUND

Management of open fractures is challenging and requires a multidisciplinary team approach. This study aims to evaluate outcomes of open Gustilo-Anderson IIIB fractures managed at a single Ortho-Plastic centre following One-stage "Fix and Flap" approach.

METHODS

Prospective data review for patients presenting with Gustilo-Anderson IIIB Fractures to our centre and managed with one-stage "Fix and Flap" approach. Postoperative outcomes are presented only for the patients who had a minimum of 12 months postoperative follow-up.

RESULTS

120 patients were included (83 males and 37 females). Mean age was 43 years (10-96). Tibia diaphysis was the most common site of injury (60%). 55.9% of injuries were road traffic accidents (RTA). 102 out of 120 patients had a minimum of 12 months follow-up (mean follow-up duration 25 months). Meantime from injury until definitive surgery was 7.71 days. Primary union achieved in 86.73%. Delayed union was encountered in 10.20%. 3.06% of patients had non-union. Limb salvage rate was 97.05% and Deep infection rate was only 0.98%.

CONCLUSION

Our results showed that low infection rate, high limb salvage rate, and high union rate can be achieved in these complex injuries with meticulous technique, combined Ortho-Plastic (Fix and Flap) approach, and MDT input.
