Skin Antisepsis before Surgical Fixation of Extremity Fractures.

BACKGROUND: Studies evaluating surgical-site infection have had conflicting results with respect to the use of alcohol solutions containing iodine povacrylex or chlorhexidine gluconate as skin antisepsis before surgery to repair a fractured limb (i.e., an extremity fracture). METHODS: In a cluster-randomized, crossover trial at 25 hospitals in the United States and Canada, we randomly assigned hospitals to use a solution of 0.7% iodine povacrylex in 74% isopropyl alcohol (iodine group) or 2% chlorhexidine gluconate in 70% isopropyl alcohol (chlorhexidine group) as preoperative antisepsis for surgical procedures to repair extremity fractures. Every 2 months, the hospitals alternated interventions. Separate populations of patients with either open or closed fractures were enrolled and included in the analysis. The primary outcome was surgical-site infection, which included superficial incisional infection within 30 days or deep incisional or organ-space infection within 90 days. The secondary outcome was unplanned reoperation for fracture-healing complications. RESULTS: A total of 6785 patients with a closed fracture and 1700 patients with an open fracture were included in the trial. In the closed-fracture population, surgical-site infection occurred in 77 patients (2.4%) in the iodine group and in 108 patients (3.3%) in the chlorhexidine group (odds ratio, 0.74; 95% confidence interval [CI], 0.55 to 1.00; P = 0.049). In the open-fracture population, surgical-site infection occurred in 54 patients (6.5%) in the iodine group and in 60 patients (7.3%) in the chlorhexidine group (odd ratio, 0.86; 95% CI, 0.58 to 1.27; P = 0.45). The frequencies of unplanned reoperation, 1-year outcomes, and serious adverse events were similar in the two groups. CONCLUSIONS: Among patients with closed extremity fractures, skin antisepsis with iodine povacrylex in alcohol resulted in fewer surgical-site infections than antisepsis with chlorhexidine gluconate in alcohol. In patients with open fractures, the results were similar in the two groups.

Immediate plate fixation of open tibial plafond fractures does not elevate risk of infection.

OBJECTIVE: To determine if immediate plate fixation of open tibial plafond fractures has a negative effect on soft tissue complications and increases the risk of deep infection. DESIGN: This was a single-institution retrospective cohort study performed at level-1 trauma center. All patients with open OTA/AO 43C plafond fractures treated over 20-year period with follow-up until fracture union or development of deep infection. Ninety-nine of 333 identified patents met the inclusion criteria. The intervention was operative treatment of open tibial plafond fractures. The main outcome measurements were return to operating room for deep infection, nonunion, and below knee amputation. RESULTS: The overall rate of complications was 52%. Gender, body mass index, tobacco use, diabetes, ASA classification, time to OR from injury, wound location, and associated fibula fracture were not associated with deep infection. There was a significant difference in Gustilo-Anderson fracture grade among infected versus non-infected (P = 0.04). There was no significant difference in postoperative infection rates between patients treated with external fixation, external fixation and limited plate fixation, and plate fixation alone during initial surgery (P = 0.64). CONCLUSION: It is well established that open pilon fractures have a high incidence for postoperative infection and development of complications such as nonunion. As these injuries have poor clinical outcomes, any additional measures to prevent infection and soft tissue complications should be utilized. In appropriately selected cases, both immediate plate fixation and immediate limited plate fixation with external fixation at the time of I&D do not appear to elevate risk of deep infection. LEVEL OF EVIDENCE: Therapeutic Level III.

Comparable Outcomes Between Native and Periprosthetic Fractures of the Distal Femur.

Despite the rising prevalence of arthroplasty and aging population, limited data exist regarding differences in periprosthetic fracture clinical outcomes compared with native counterparts. This study compares differences in hospital treatment, morbidity, and mortality associated with periprosthetic distal femur fractures at an urban level 1 trauma center. We retrospectively reviewed all adult AO/OTA type 33 fractures (526) that presented to our institution between 2009 and 2018. In total, 54 native and 54 periprosthetic fractures were matched by age and gender. We recorded demographics, operative measures, length of stay (LOS), discharge disposition, and mortality. We used McNemar's and paired t-tests for analysis where appropriate (p < 0.05) (IBM SPSS Statistics for Windows, Version 26.0. Armonk, NY; IBM Corp.). The average age at injury was 74 years ± 12 (native) compared with 73 years ± 12 (periprosthetic). After 1:1 matching, the groups had similar body mass index (31.01 vs. 32.98, p = 0.966 for native and periprosthetic, respectively) and mechanisms of injury with 38 native and 44 periprosthetic (p = 0.198) fractures from low-energy falls. Both groups had 51/54 fractures managed with open reduction internal fixation with a locking plate. The remaining were managed via amputation or intramedullary nail fixation. Mean operative time (144 minutes (±64) vs. 132 minutes (±62), p = 0.96) and estimated blood loss (319 mL (±362) vs. 289 mL (±231), p = 0.44) were comparable between the native and periprosthetic groups, respectively. LOS: 9 days ± 7 (native) versus 7 days ± 5 (periprosthetic, p = 0.31); discharge disposition (to skilled nursing facility/rehab): n = 47 (native) versus n = 43 (periprosthetic, p = 0.61); and mortality: n = 6 (native) versus n = 8 (periprosthetic, p = 0.55). No significant differences were observed. We found no statistical differences in morbidity and mortality in periprosthetic distal femur fractures treated over 10 years at a level 1 trauma center. Native and periprosthetic AO/OTA type 33 distal femur fractures are serious injuries with similar outcomes at a level 1 trauma center.

Interprosthetic Femur Fractures: A Review Article.

➢: The prevalence of interprosthetic femur fractures (IFFs) is rising with the aging population and increased prevalence of total joint arthroplasty. ➢: IFFs have high rates of complications and high associated morbidity and mortality. ➢: The main treatment methods available for IFFs include plate fixation, intramedullary nailing, combined plate fixation and intramedullary nailing, and revision arthroplasty including partial and total femur replacement. ➢: There have been several proposed classification systems and at least 1 proposed treatment algorithm for IFFs; however, there is no consensus. ➢: Whichever treatment option is chosen, goals of surgery should include preservation of blood supply, restoration of length, alignment, rotation, and sufficient stabilization to allow for early mobilization.

Traumatic Dislocation of the Proximal Tibiofibular Joint: A Systematic Review and 10-year Experience From a Level 1 Trauma Center.

INTRODUCTION: Traumatic proximal tibiofibular joint dislocations occur infrequently and are typically the result of high-energy trauma. These injuries can be a marker of limb injury severity because patients often sustain vascular injury and are at high risk of amputation. The purpose of this study was to present a systematic review of traumatic proximal tibiofibular joint dislocations and compare rates of associated injuries with a retrospective series of patients at a level 1 trauma center. The secondary objective was to report rates and clinical predictors of limb amputation. METHODS: A systematic review was conducted, identifying three studies meeting eligibility criteria. A retrospective chart review was conducted identifying 17 skeletally mature patients with proximal tibiofibular dislocation treated from January 2010 to February 2021. A chart review extracted patient demographics, fracture patterns, open fracture, preoprative and postoperative peroneal nerve injury, vascular injury, and amputation. Binary logistic regression analysis was used to identify clinical predictors of outcomes. RESULTS: Sixteen of 17 proximal tibiofibular injuries (94.1%) were associated with fracture, most commonly tibial shaft (n = 11, 68.75%). Twelve of 17 fractures (76.5%) were open. Five vascular injuries (29.4%) occurred requiring surgical intervention. Seven (41.2%) preoperative peroneal nerve deficits were noted; six had persistent deficits postoperatively or underwent amputation (average follow-up 31.3 ± 32.6 months). Two patients in the sample without preoperative peroneal nerve deficits were noted to exhibit them after fixation. Eight patients (47%) underwent an amputation, 7 (87.5%) of whom had an open fracture and 4 (50%) of whom had documented vascular injury. DISCUSSION: Traumatic proximal tibiofibular fractures indicate severe injury to the lower extremity with high risk for nerve injury and possible amputation. Patients who present with vascular injury and open fracture in association with proximal tibiofibular joint disruption may be at elevated risk of amputation.

Suture Fixation of a Pediatric Pelvic Ring Injury: A Case Report.

CASE: A 2-year-old male child presented as a polytrauma after having been run over by a motor vehicle. His orthopaedic injuries included a pelvic ring injury, a displaced subtrochanteric femur fracture, and a clavicle fracture. His pelvic ring injury ultimately required open reduction with suture fixation after failure of closed management. CONCLUSION: Pelvic ring injuries are relatively uncommon in young children, and even more rarely do they require surgical intervention. We detail the case of one such patient who required open management of his anteroposterior compression II pelvic ring injury, and we describe an alternative fixation technique using suture wire.

Technique for Open Reduction and Internal Fixation of Lateral Process Talus Fractures.

Lateral process fractures of the talus may occur either in isolation or in combination with a talar neck or body fracture. Screw fixation has been well described as a means of stabilization; however, many patients have multifragmentary fragments, unable to be controlled by isolated screw fixation alone. Plate fixation of the lateral process has been yet to be described in detail with presence of a clinical series. Here, we describe our technique of plate fixation for both isolated lateral process fractures and those that occur in conjunction with talar neck or body fracture.

Significance of Lateral Process Fractures Associated With Talar Neck and Body Fractures.

OBJECTIVES: To determine whether fracture of the lateral process (LP) elevates the risk of development of radiographic subtalar arthrosis in patients with talar body and neck fractures. DESIGN: Retrospective review. SETTING: Level 1 academic trauma center. PATIENTS/PARTICIPANTS: Eighty-two patients with 43 talar neck and 43 talar body fractures treated over a 5-year period. INTERVENTION: Preoperative and postoperative radiographs were evaluated for fracture of the LP of the talus and subsequent development of radiographic subtalar arthritis. MAIN OUTCOME MEASUREMENTS: Radiographic evidence of subtalar arthritis. RESULTS: Seventy-six percent of talar neck fractures with involvement of the LP went on to develop radiographic evidence of subtalar arthrosis compared with 36% of talar neck fractures without LP involvement (P = 0.035). Thirty of the fractures involving the LP had a separate LP fragment. Fifteen of the 30 fractures with a separate LP fragment that underwent reduction and fixation developed radiographic evidence of subtalar arthrosis, whereas all 13 fractures with an independent LP fragment that did not have fixation of the LP went on to develop radiographic evidence of subtalar arthritis (P = 0.001). Comminution of the inferior talar articular surface was found to significantly increase the risk of radiographic subtalar arthritis in both talar body and talar neck fractures (P = 0.0003). An anatomic reduction of both talar neck and body fractures was found to be associated with a lower incidence of radiographic subtalar arthritis (P = 0.00001). CONCLUSION: Comminution of the inferior articular surface of the talus elevates the risk of subtalar arthritis in patients with both talar neck and body fractures. Fracture of the LP is a marker for injury to the talar inferior articular surface and increases the risk for the radiographic finding of subtalar arthritis in patients with talar neck fractures. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Interprosthetic Fractures of the Femur.

As the rate of hip and knee arthroplasty procedures increases, so will the rate of interprosthetic fractures. Several factors, including bone quality, bone quantity, and stability of the prosthetic components, play a role in determining the appropriate operative treatment. Patients with stable components should undergo reduction and internal fixation, while patients with loose components should undergo either revision arthroplasty, with or without additional fixation, or conversion to total femur replacement. Despite implant and technique advances, complications remain frequent. [Orthopedics. 2018; 41(1):e1-e7.].

Incidence of Vacuum Phenomenon Related Intra-articular or Subfascial Gas Found on Computer-Assisted Tomography (CT) Scans of Closed Lower Extremity Fractures.

OBJECTIVES: To determine the incidence of vacuum phenomenon related intra-articular or subfascial gas found on computer-assisted tomography (CT) scans of closed lower extremity fractures. DESIGN: Retrospective Review. SETTING: Level I Trauma Center. PATIENTS/PARTICIPANTS: A total of 153 patients with closed lower extremity fractures. INTERVENTION: CT scans of identified individuals were reviewed for the presence or absence of gaseous accumulations. MAIN OUTCOME MEASUREMENTS: The presence or absence of gas on CT. RESULTS: Twenty seven (17.6%) of the 153 fractures were found to have intra-articular or subfascial gas on CT despite clear documentation, indicating a closed injury with no significant skin compromise. Of the intra-articular fractures (OTA/AO 33B/C, 41B/C and 43B/C), 20% (23 of 113) were found to have gas on CT. All cases were associated with fracture of the tibia (P = 0.002). CONCLUSIONS: Computed tomography demonstrated the presence of intra-articular or subfascial gas in 17.6% (27/153) of closed lower extremity fractures and in 20% (23/113) of closed intra-articular fractures. The possibility of vacuum phenomenon must be considered when using this imaging modality as the confirmatory test for open intra-articular fracture or traumatic arthrotomy. LEVEL OF EVIDENCE: Level IV.

Palliative Management of Nonoperative Femoral Neck Fractures With Continuous Peripheral Pain Catheters: 20 Patient Case Series.

INTRODUCTION: To identify the success of pain catheters in the management of pain in nonoperatively treated femoral neck fractures (FNFs) in supplement to current multimodal protocols for end-of-life pain management. METHODS: Twenty patients aged older than 50 years with FNFs were selected in a retrospective fashion at a level 1 trauma center. These patients were treated nonoperatively with indwelling continuous peripheral pain catheters to palliate pain. Adjunctive pain control for patients undergoing nonoperative management of FNFs was provided with an indwelling continuous intra-articular/peripheral nerve ropivacaine pain catheters. Pain scores 24 hours before/after continuous pain catheter placement, ambulation status before/after continuous pain catheter placement, mortality at 30 days/1 year, and length of hospital stay were measured. RESULTS: Twenty patients were identified with an average age of 84.55 years. The average length of stay was 4.85 days with a decrease of 4.45 points on the visual analog scale and an improvement of 90% in ambulation status. Thirty-day and one-year mortality were 65% and 95%, respectively. CONCLUSION: This case series provides orthopedic surgeons with an option for and data on the success of this adjunct to palliate patients who elect to undergo nonoperative management of FNFs. This study also helps define which patients may be candidates for nonoperative management of geriatric hip fractures.
