RESUMO
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.

PURPOSE: Retrograde femoral intramedullary nailing (IMN) is commonly used to treat distal femur fractures. There is variability in the literature regarding the ideal starting point for retrograde femoral IMN in the coronal plane. The objective of this study was to identify the ideal starting point, based on radiographs, relative to the intercondylar notch in the placement of a retrograde femoral IMN. METHODS: A consecutive series of 48 patients with anteroposterior long-leg radiographs prior to elective knee arthroplasty from 2017 to 2021 were used to determine the femoral anatomic axis. The anatomic center of the isthmus was identified and marked. Another point 3 cm distal from the isthmus was marked in the center of the femoral canal. A line was drawn connecting the points and extended longitudinally through the distal femur. The distance from the center of the intercondylar notch to the point where the anatomic axis of the femur intersected the distal femur was measured. RESULTS: On radiographic review, the distance from the intercondylar notch to where the femoral anatomic axis intersects the distal femur was normally distributed with an average distance of 4.1 mm (SD, 1.7 mm) medial to the intercondylar notch. CONCLUSION: The ideal start point, based on radiographs, for retrograde femoral intramedullary nailing is approximately 4.1 mm medial to the intercondylar notch. Medialization of the starting point for retrograde intramedullary nailing in the coronal plane aligns with the anatomic axis. These results support the integration of templating into preoperative planning prior to retrograde IMN of the femur, with the knowledge that, on average, the ideal start point will be slightly medial. Further investigation via anatomic studies is required to determine whether a medial start point is safe and efficacious in patients with distal femur fractures treated with retrograde IMNs.

Distal femoral skeletal traction is a common procedure for the stabilization of fractures of the pelvis, acetabulum, and femur following trauma. Femoral traction pins are traditionally inserted via medial-to-lateral (MTL) entry to accurately direct the pin away from the medial neurovascular bundle. Alternatively, cadaveric studies have demonstrated low risk to the neurovascular bundle using a lateral-to-medial (LTM) approach. The purpose of this study was to compare the incidence of complications of LTM and MTL femoral traction pin placement at a single institution. This was a retrospective review of patients from the orthopaedic consult registry at a academic Level I Trauma Center. We identified 233 LTM femoral traction pin procedures in 231 patients and 29 MTL pin procedures in 29 patients. The two pin placement techniques were compared with respect to complications, specifically the incidence of neurovascular injury, cellulitis, septic arthritis, osteomyelitis, and heterotopic ossification after femoral traction pin placement. Two complications were reported. One patient developed heterotopic ossification along the pin tract after LTM traction pin placement. Another patient developed septic arthritis after LTM pin placement, likely attributable to retrograde intramedullary nailing of his open femur fracture rather than his traction pin. There were no reports of neurovascular injury, cellulitis, or osteomyelitis associated with pin placement. The complication rate was 0.9% for LTM group and 0.0% for MTL group (p = 0.616). LTM femoral traction pin placement is a safe procedure with a similarly low complication rate compared with traditional MTL placement when the limb is positioned in neutral alignment.

This study's objective was to identify a difference in maximum temperature change during forward versus oscillating drilling of cadaveric bone. Paired femurs were dissected from the soft tissue of five cadavers. Each cadaver had one femur assigned to forward and the other to oscillation. The first drill hole was 2.5 cm distal to the lesser trochanter and the remaining 10 holes were evenly spaced 2 cm apart. A System 7 drill and 3.5 mm drill bit were attached to an Instron 5500R to provide a progressive force of 50 Newtons per minute for each drill hole. A thermal camera recorded each drilling. A new drill bit was used for each femur. Fifty bicortical drillings were analyzed in each group. The average time to complete forward drilling (45.0 seconds) was shorter compared to oscillation (55.5 s, p < 0.001). The average force required for forward drilling (27.7 N) was lower than for oscillation (44.3N, p < 0.001). The maximum change in temperature during the drilling process was similar (oscillating 100.2° F vs. forward 100.7° F, p = 0.871). The maximum change in temperature at the near cortex was lower for oscillation (78.1°F) compared to forward drilling (89.1°F, p = 0.011), while the maximum change at the far cortex was lower for forward drilling (89.3°F) compared to oscillation (95.8°F, p = 0.115) but not significantly. Overall, there is no difference in the thermal output between techniques. Oscillation may be beneficial in proximity to vital structures or to navigate narrow bony corridors, but it requires additional time and force.

Vancouver B1 periprosthetic fractures undergoing operative fixation remain difficult to treat due to a short proximal segment that offers limited options for fixation. The trochanteric hook plate addresses this issue by maximizing proximal purchase and utilizing the entire lateral surface area of the greater trochanter. A surgical technique that prioritizes proximal fixation and adheres to basic principles resulted in all fractures healing in a small case series.

The objective of this study was to describe examples and review the literature of distal humerus fracture reconstruction in the setting of severe bone loss. Four individuals (ages 19-59 years) were treated with either fibular strut allograft or fresh frozen osteochondral allograft in the setting of unreconstructable periarticular bone loss. The radiographs were evaluated for evidence of union. Pain and degrees of range of motion were reported when available. The follow-up period ranged from 3 to 42 months. While additional surgery was often needed, union was ultimately obtained in each case. Normal range of motion was not obtained, but two of the four patients were near normal upon union. Two of the four patients were pain free, and the other two had mild pain. All were limited in their activities, even after union. This case series describes satisfactory results with the use of allograft in this difficult clinical problem. (Journal of Surgical Orthopaedic Advances 29(2):65-72, 2020).

The goal of treatment for distal radius fractures is anatomic articular reduction and restoration of coronal and sagittal plane alignment, rotation, and angulation of the metadiaphyseal component of these fractures. This article presents a reproducible technique for restoring coronal plane alignment of the metadiaphyseal component of the fracture using an indirect reduction maneuver leveraging the volar locking plate as an indirect reduction aid. After applying an appropriately sized volar locking plate, the first screw is placed in the center of the shaft of the plate. Next, the distal row of subarticular locking screws is placed to neutralize a reduced articular surface. The shaft screw is subsequently loosened, and two Freer elevators are used to rotate the plate, indirectly translating the distal articular block and achieving improved coronal plane alignment. Last, the remaining diaphyseal screws are applied to appropriately neutralize the fracture. (Journal of Surgical Orthopaedic Advances 27(2):160-163, 2018).

The purpose of this study was to evaluate midterm outcomes after both bone forearm fractures. A retrospective review of patients treated with open reduction and internal fixation (ORIF) at three level 1 trauma centers was completed. Eligible patients were sent three questionnaires: Disabilities of the Arm, Shoulder and Hand (DASH), Short Form-12 (SF-12), and questions about postinjury experience. Twenty-nine patients with an average age of 45 years returned the materials. The forms were completed an average of 60 months after ORIF. The mean DASH was 22 for all respondents. Twenty-one subjects participated in physical therapy (72%). Eight patients (28%) screened positive for posttraumatic stress disorder (PTSD). The mean SF-12 physical component score was 39 and the SF-12 mental component score was 40, both of which were lower than the non-PTSD group, indicating a lower subjective level of health (p < .05). The data suggest that, years after surgery, patients have decreased functional outcomes.

The current report describes a revision total hip arthroplasty in which the trial femoral head disassociated during reduction and migrated into a soft tissue capsule of the true pelvis between the external iliac vein and corona mortise. The authors believe this previously undescribed migration pattern was created by the patient's history of recurrent dislocations. To retrieve the trial prosthesis without injuring the adjacent vasculature, a secondary surgical approach was utilized. The described case identifies the risk of pelvic migration in patients with a history of dislocations and reminds us that a secondary surgical approach should be considered to avoid devastating injury to the neighboring vasculature.

OBJECTIVES: Dual implants for distal femur periprosthetic fractures is a growing area of interest for these challenging fractures with dual plating (DP) emerging as a viable construct for these injuries. In the current study, an experience with DP constructs is described. DESIGN: Retrospective case series with comparison group. SETTING: Level 1 academic trauma center. PATIENT SELECTION CRITERIA: Adults >50 years old sustaining comminuted OTA/AO 33-A2 or 33-A3 DFPF treated with either DP or a single distal femur locking plating (DFLP). Patients with simple 33-A1 fractures were excluded. Prior to 2018, patients underwent DFLP after which the treatment of choice became DP. OUTCOME MEASURES AND COMPARISONS: Reoperation rate, alignment, and complications. RESULTS: 34 patients treated with DFLP and 38 with DP met inclusion and follow up criteria. Average follow up was 18.2 ± 13.8 months in the DFLP group and 19.8 ± 16.1 months in the DP group ( P = 0.339). The average patient age in the DFLP group was 74.8 ± 7.3 years compared to 75.9 ± 11.3 years in the DP group. There were no statistical differences in demographics, fracture morphology, loss of reduction, or reoperation for any cause ( P >.05). DP patients were more likely to be weight bearing in the twelve-week postoperative period ( P <0.001) and return to their baseline ambulatory status ( P = 0.004) compared to DFLP patients. CONCLUSIONS: Dual plating of distal femoral periprosthetic fractures maintained coronal alignment with a low reoperation rate even with immediate weight bearing and these patients regained baseline level of ambulation more reliably as compared to patients treated with a single distal femoral locking plate. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVE: To evaluate risk factors for infection in severe open tibial shaft fractures. METHODS: A secondary analysis of a multicenter prospective study investigated internal versus external fixation of severe open tibia fractures at 20 US Level I trauma centers. Adult patients, aged <65 years, with a Gustilo-Anderson Type IIIB or severe IIIA metaphyseal or diaphyseal tibia fracture were included. All fractures underwent definitive fixation with either a modern ring external fixator, intramedullary device, and/or plate. Fourteen variables previously identified as risk factors for infection were included in the analysis. Deep surgical site infection was defined as an infection treated with surgical debridement within 1 year of index surgery. RESULTS: The study cohort included 430 patients. Deep surgical site infection requiring reoperation occurred in 108 (25 %) patients. The final model identified four risk factors for infection: age >40 years (OR, 2.00; 95 % CI, 1.3-3.1), Gustilo-Anderson Type IIIB (OR, 1.80; 95 % CI, 1.1-3.0), embedded wound contamination (OR, 1.69; 95 % CI, 1.1-2.7), and wound length (OR, 1.02/cm; 95 % CI, 1.0-1.05). The model performed poorly at distinguishing infected from uninfected patients (Area Under the Curve=0.57; 95 % CI, 0.51-0.63). CONCLUSIONS: Surgeons can now counsel patients with these risk factors that they are at a markedly higher risk of infection. The identification of these risk factors may direct future research aimed at mitigating the risk of deep surgical site infection in this patient population.
RESUMO
Transabdominal gunshot wounds (GSWs) of the hip and pelvis are those that traverse the gastrointestinal system before entering the pelvis and/or hip. These injuries may be contaminated by bowel contents. Some require urgent surgical intervention; others can be managed nonsurgically. A primary survey with attention to hemodynamic status is of utmost priority. After obtaining hemodynamic stability and addressing abdominal injuries, careful attention must be paid to evaluating hip joint involvement and injuries to the genitourinary and vascular systems. The available literature shows that transabdominal GSW with intra-articular contamination should be urgently débrided and irrigated; extra-articular transabdominal GSW with stable fracture patterns may be managed with observation and empiric antibiotics. Extent of soft-tissue injury dictates the need for wound débridement. Bullets lodged in intra-articular locations should be removed, but retained bullets in other anatomic locations do not necessarily warrant removal.

Iliosacral screw removal is occasionally necessary during index or revision pelvic ring surgery. This procedure can necessitate a two-step process: screw removal followed by retained washer removal. On attempted removal of the screw-washer complex, the washer will not uncommonly dissociate itself from the screw. Its retrieval can be challenging, add unnecessary operative time, and result in larger incisions and increased soft tissue disruptions. This article introduces a simple technique for retained washer retrieval when removing or exchanging iliosacral screws. This technique involves an "interference fit" between the retained washer and a screw or tap of larger diameter, allowing for reliable and simple washer extraction. Advantages of this technique include removal through the same soft tissue tract as initial screw insertion and subsequent screw removal. It also obviates the need for introduction of various clamps to extract the washer, which can result in soft tissue injury and increased reliance on fluoroscopy.

Humeral shaft fractures account for approximately 3% of all fractures. Nonsurgical management of humeral shaft fractures with functional bracing gained popularity in the 1970s, and this method is arguably the standard of care for these fractures. Still, surgical management is indicated in certain situations, including polytraumatic injuries, open fractures, vascular injury, ipsilateral articular fractures, floating elbow injuries, and fractures that fail nonsurgical management. Surgical options include external fixation, open reduction and internal fixation, minimally invasive percutaneous osteosynthesis, and antegrade or retrograde intramedullary nailing. Each of these techniques has advantages and disadvantages, and the rate of fracture union may vary based on the technique used. A relatively high incidence of radial nerve injury has been associated with surgical management of humeral shaft fractures. However, good surgical outcomes can be achieved with proper patient selection.

The elderly have conventionally been defined as individuals over the age of 65 and are projected to represent about 21% of the United States (US) population by the year 2030. Distal radius fractures (DRF) in particular are one of the most common fractures among elderly patients and their incidence continues to rise in part due to increased activity levels among the elderly, increased life expectancy, rising rates of obesity, changes to dietary habits, and the prevalence of osteoporosis. Although various treatment options exist for these injuries, nonsurgical treatment of distal radius fractures remains a mainstay among elderly patients with mounting evidence of its non-inferiority to surgical fixation in the literature. Here, we summarize the overall approach to nonsurgical treatment of distal radius fractures in the elderly population while examining its supporting data and highlighting potential risks and limitations to it.
RESUMO
Background: Recent studies have reported that targeting a center-center position at the distal tibia during intramedullary nailing (IMN) may result in malalignment. Although not fully understood, this observation suggests that the coronal anatomic center of the tibia may not correspond to the center of the distal tibia articular surface. Questions/Purposes: To identify the coronal anatomic axis of the distal tibia that corresponds to an ideal start site for IMN placement utilizing intact cadaveric tibiae. Methods: IMN placement was performed in 9 fresh frozen cadaveric tibiae. A guidewire was used to identify the ideal start site in the proximal tibia and an opening reamer allowed access to the canal. Each nail was then advanced without the use of a reaming rod until exiting the distal tibia plafond. Cadaveric and radiographic measurements were performed to determine the center of the nail exit site in the coronal plane. Results: Cadaveric and radiographic measurements identified the IMN exit site to correspond with the lateral 59.5% and 60.4% of the plafond, respectively. Conclusions: Tibial nails inserted using an ideal start site have an endpoint that corresponds roughly to the junction of the lateral and middle third of the plafond. Further studies are warranted to better understand the impact of IMN endpoint placement on the functional and radiographic outcomes of tibia shaft fractures.
RESUMO
OBJECTIVE: To compare the retrospective decision of an expert panel who assessed likelihood of acute compartment syndrome (ACS) in a patient with a high-risk tibia fracture with decision to perform fasciotomy. DESIGN: Prospective observational study. SETTING: Seven Level 1 trauma centers. PATIENTS/PARTICIPANTS: One hundred eighty-two adults with severe tibia fractures. MAIN OUTCOME MEASUREMENTS: Diagnostic performance (sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and receiver-operator curve) of an expert panel's assessment of likelihood ACS compared with fasciotomy as the reference diagnostic standard. SECONDARY OUTCOMES: The interrater reliability of the expert panel as measured by the Krippendorff alpha. Expert panel consensus was determined using the percent of panelists in the majority group of low (expert panel likelihood of ≤0.3), uncertain (0.3-0.7), or high (>0.7) likelihood of ACS. RESULTS: Comparing fasciotomy (the diagnostic standard) and the expert panel's assessment as the diagnostic classification (test), the expert panel's determination of uncertain or high likelihood of ACS (threshold >0.3) had a sensitivity of 0.90 (0.70, 0.99), specificity of 0.95 (0.90, 0.98), PPV of 0.70 (0.50, 0.86), and NPV of 0.99 (0.95, 1.00). When a threshold of >0.7 was set as a positive diagnosis, the expert panel assessment had a sensitivity of 0.67 (0.43, 0.85), specificity of 0.98 (0.95, 1.00), PPV of 0.82 (0.57, 0.96), and NPV of 0.96 (0.91, 0.98). CONCLUSION: In our study, the retrospective assessment of an expert panel of the likelihood of ACS has good specificity and excellent NPV for fasciotomy, but only low-to-moderate sensitivity and PPV. The discordance between the expert panel-assessed likelihood of ACS and the decision to perform fasciotomy suggests that concern regarding potential diagnostic bias in studies of ACS is warranted. LEVEL OF EVIDENCE: Diagnostic Level I. See Instructions for Authors for a complete description of levels of evidence.

External fixation is an important option in the acute management of unstable femoral and tibial fractures and the temporary stabilization of periarticular injuries of the knee or ankle. The value of external fixation as the modality of choice in selective civilian and military applications is well documented. Primary indications include damage control for multitrauma management in patients with concomitant traumatized integument and/or excessive swelling and/or systemic instability and stabilization for transport in hostile or austere environments. The purpose of this article is to discuss the indications for temporary external fixation of lower extremity long bones and complicated distal femoral, proximal tibia, and tibial plafond fractures; to outline technical considerations in the application of temporary external fixation devices; and to summarize the experience in the use of prepackaged external fixators and their indications in combat.

SUMMARY: Distal radius fractures are common in the geriatric population; however, treatment of these fractures remains controversial. Patients undergoing operative fixation may experience a quicker recovery with increased grip strength, which is beneficial in the active geriatric patient. Treatment options include fragment-specific fixation, volar locked plating, and dorsal bridge plating. External fixation alone leads to poor outcomes and is indicated in patients with soft tissue compromise or as a supplemental aid. Implant selection should be tailored to fracture parameters. With a thoughtful surgical algorithm and rehabilitation protocol, good outcomes can be achieved with a high rate of patient satisfaction.

SUMMARY: Distal femur fractures in the elderly have been historically treated with locked plating or retrograde intramedullary nailing with good, reliable results. However, in certain more complex fracture patterns (native or periprosthetic), increased density of fixation via dual-plate or nail plate combination can help achieve immediate weight-bearing. It can also potentially increase rates of union by shifting and maintaining the neutral axis, distributing forces more evenly across the fracture site. Here, we discuss the indications, pros and cons of both dual-plate and nail plate combination techniques in a concise case-based format.
