Safety of Prepping the External Fixator In Situ During Staged Internal Fixation of Pilon Fractures: A Retrospective Comparative Cohort Study.

ABSTRACT:

Objective

(1) To assess the rate of fracture-related infection (FRI) and unplanned reoperation of disinfecting and prepping in the external fixator (Ex-Fix) instrument during definitive open reduction and internal fixation (ORIF) of pilon fractures treated by a staged protocol and (2) to determine whether the amount of time from external fixation to ORIF influences the risk of FRI.

Design

Retrospective cohort study.

Setting

Level 1 academic trauma center.

Patients

One hundred thirty-three patients who underwent operative treatment for pilon fracture between 2010 and 2020.

Intervention

External fixation and ORIF with or without the Ex-Fix prepped in situ during definitive fixation.

Main outcome measurements

FRI and unplanned reoperation rates.

Results

133 patients were enrolled, of which 47 (35.3%) had Ex-Fix elements prepped in situ. There was an overall infection rate of 23.3% and unplanned reoperation rate of 11.3%, and there was no significant difference in rates between the 2 cohorts. Patients with Ex-Fix elements prepped in situ who developed an FRI had a higher rate of MRSA and MSSA . Diabetes ( P = 0.0019), open fracture ( P = 0.0014), and longer (≥30 days) interval to ORIF ( P = 0.0001) were associated with postoperative FRI.

Conclusions

Prepping elements of the Ex-Fix in situ did not lead to an increase in rates of FRI or unplanned reoperation. Although diabetes and open fracture were associated with FRI risk, a stronger association was a longer interval of Ex-Fix utilization before definitive internal fixation, specifically 30 days or greater.

Project description:The aim of this study was to compare the biomechanical stability and clinical outcome of external fixator combined with limited internal fixation (EFLIF) and open reduction and internal fixation (ORIF) in treating Sanders type 2 calcaneal fractures.Two types of fixation systems were selected for finite element analysis and a dual cohort study. Two fixation systems were simulated to fix the fracture in a finite element model. The relative displacement and stress distribution were analysed and compared. A total of 71 consecutive patients with closed Sanders type 2 calcaneal fractures were enrolled and divided into two groups according to the treatment to which they chose: the EFLIF group and the ORIF group. The radiological and clinical outcomes were evaluated and compared.The relative displacement of the EFLIF was less than that of the plate (0.1363 mm to 0.1808 mm). The highest von Mises stress value on the plate was 33% higher than that on the EFLIF. A normal restoration of the Böhler angle was achieved in both groups. No significant difference was found in the clinical outcome on the American Orthopedic Foot and Ankle Society Ankle Hindfoot Scale, or on the Visual Analogue Scale between the two groups (p > 0.05). Wound complications were more common in those who were treated with ORIF (p = 0.028).Both EFLIF and ORIF systems were tested to 160 N without failure, showing the new construct to be mechanically safe to use. Both EFLIF and ORIF could be effective in treating Sanders type 2 calcaneal fractures. The EFLIF may be superior to ORIF in achieving biomechanical stability and less blood loss, shorter surgical time and hospital stay, and fewer wound complications.Cite this article: M. Pan, L.

Project description:BackgroundTo explore the application and clinical efficacy of surgical approach strategies in open reduction internal fixation of closed complex tibial Pilon fractures based on axial CT scans.MethodsThis retrospective cohort study included data of 25 patients with closed complex tibial Pilon fractures treated from October 2011 to March 2014, including 19 males and 6 females aged 18-54 years (average 39.5 years). According to classification criteria of the Association for Osteosynthesis/Orthopedic Trauma Association (AO/OTA), 4 patients were type 43C1, 10 type 43C2, and 11 type 43C3. Surgical approaches were selected based on fracture line distribution and bone displacement revealed by axial CT scans, and an open reduction method was adopted for internal fixation of the bone plates. Postoperatively, Burwell-Charnley radiographic criteria were used to determine fracture reduction quality. Functional evaluation was performed using the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. Complications, fracture union time, and the AOFAS scores at last follow-up were recorded.ResultsThe 25 included patients were followed for 22-60 months postoperatively (average follow-up 33.9 months). Of these, 19 patients achieved anatomical reduction of the articular surface, 5 achieved good reduction, and one achieved fair reduction. Two patients developed superficial infection on the anteromedial incision and delayed union but recovered well after local dressing change and oral administration of antibiotics. Another patient developed deep infection on the anterolateral incision, which was controlled by debridement, catheter irrigation, and intravenous antibiotic injection. All fractures healed well and average union time was 2.8 months (range, 2-3 months). No fracture malunion or internal fixation failures were found at last follow-up. All 25 patients had AOFAS scores ranging from 80 to 100 at last follow-up (average 88.4). Overall, 15 patients were excellent, 10 good, and 0 fair or poor, with excellent and good rates of 100%.ConclusionsSurgical approach strategies for complex tibial Pilon fractures based on axial CT scans accurately reconstruct the articular surface and achieve solid internal fixation of assembled locking plates, while early postoperative functional exercises contribute to the functional recovery of affected limbs and reduce related complications.

Project description:Background The present study sought to explore the efficacy of one-third tubular steel plates and screws for the treatment of medial column of pilon fractures. Methods The present retrospective study comprised 40 subjects with Rüedi-Allgöwer type III pilon fractures that attended Northern Jiangsu People’s Hospital from April 2016 to April 2019. Patients were assigned to 2 groups based on reconstruction and fixation components used on the medial column. The medial column of participants in the control group (n=20) was anchored using screws. The medial column for subjects in the treatment group (n=20) was reconstructed using a one-third tubular steel plate. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score at 1, 2, 3, 6, 12 and 24 months after operation, intraoperative blood loss, fracture healing time, preoperative detumescence duration, operation time, postoperative weightbearing duration, and postoperative Burwell-Charnley radiological score of the 2 groups were compared. Results The findings showed that intraoperative blood loss, preoperative detumescence time, and operation time for the treatment group were not statistically different relative to the control group (P>0.05). The fracture healing time and postoperative weightbearing time in the treatment group were 15.07±0.98 weeks and 6.91±0.61 weeks, respectively, while those in the control group were 15.84±0.59 weeks and 8.60±0.53 weeks, respectively (P<0.05). Patients in the treatment group showed markedly higher AOFAS scores relative to the AOFAS scores of subjects in the control group at month 1, 2, and 3 post-operation (P<0.05). AOFAS scores for the 2 groups were not significantly different at month 6, 12 and 24 post-operation. Subjects in the control group had a significantly lower Burwell-Charnley number radiology score relative to that of subjects in the treatment group (P<0.05). Conclusions The present findings show that the medial column of subjects with Rüedi-Allgöwer type III pilon fracture can be repaired using a one-third tubular steel plate. Compared with simple screw fixation, the use of a one-third tubular steel plate allows earlier postoperative weightbearing, decreases the rate of postoperative reduction loss, and leads to better clinical effects and prognosis.
