UNASSIGNED: The zygomatic arch is important to maintain facial projection as well as width. Hence, restitution of its form by open reduction and internal fixation (ORIF) is indicated following its fracture, in certain clinical scenarios. The contemporary surgical approaches are cutaneous with associated complications. This observational clinical trial was designed to evaluate intraoral reduction and transbuccal fixation of zygomatic arch fractures.
UNASSIGNED: Six patients requiring ORIF of the zygomatic arch were recruited for the study. The clinical parameters such as pain, swelling, mouth opening, facial nerve function, and scar were assessed in the pre-operative as well as post-operative period. Radiographic assessment of displacement and inter-fragmentary separation were studied on computed tomography (CT) images.
UNASSIGNED: Mean pre-operative mouth opening was increased from 28.33 ± 6.80 to 36.83 ± 1.94 (P value 0.03). Mean pre-operative swelling was decreased from 34.63 ± 5.41 to 29.71 ± 2.73 (P value 0.02). The pain decreased by day 7 in all the patients (P value 0.01). No facial nerve injury (P value 1) or scar formation (P value 0.002) was encountered in our study. The inter-fragmentary separation as assessed by CT analysis revealed satisfactory outcome.
UNASSIGNED: Intraoral open reduction and transbuccal fixation is a simple, effective, and less invasive method to address zygomatic arch fractures with no complications.

BACKGROUND: Fractures of the distal femoral third are an important cause of morbidity and mortality, and their treatment is currently controversial.
OBJECTIVE: To compare the results between minimally invasive techniques versus exposure of the fracture site. Secondly, to evaluate the relationship between demographic factors, mechanism of injury and surgical delay with patient prognosis.
METHODS: Retrospective cohort study carried out between 2015 and 2021 in a tertiary hospital. Data collection was performed by reviewing medical histories, measuring demographic and hospital parameters and definitive treatment strategy. One year of follow-up was completed in all patients, assessing the occurrence of surgical complications and mortality. A stratified analysis of the variables of interest was performed among patients over 65 years of age.
RESULTS: 128 fractures were recorded, with definitive osteosynthesis being performed in 117. Patients who underwent minimally invasive techniques required a shorter hospital stay (9 [7-12] vs. 12 [8.75-16] days) (p=0.007), with no differences in mortality or complications during follow-up. In those over 65 years of age, opening the fracture site was associated with an increased risk of infection compared to minimally invasive techniques (33.3% vs. 2%) (p=0.507). All the deceased were patients over 65 years of age (33.7% at one year). Surgical delay longer than 48h increased mortality by 10% among those older than 65 years (p=0.3). High-energy trauma had a higher proportion of pseudarthrosis (27.6% vs. 6.1%) (p=0.011).
CONCLUSIONS: Minimally invasive techniques decreased hospital stay but not complications or long-term mortality.
METHODS: IIb.

UNASSIGNED: To assess the efficacy of Herbert cannulated bone screw versus Lag screw in fixation of oblique mandibular fractures.
UNASSIGNED: Study composed of two groups of 20 patients each and descriptive statistics were performed with p value set at 0.05 with confidence interval of 95%. Group A was treated by Titanium Lag screws; while, Group B was treated by Titanium Herbert Cannulated Bone Screws for the management of oblique mandibular fractures. Postoperatively, all the patients were evaluated clinically and radiographically by recording the incidence of complications (if any) which included trismus, neurosensory deficit, swelling, infection. Parameters such as occlusal discrepancy, rigid fixation (interfragmentary gap) and duration of surgery were also recorded for all the patients.
UNASSIGNED: All the patients were followed for a period of three months. Difference in mouth opening was found to be statistically significant during 1st month follow-up (p-Value-0.002). Postoperatively, the mean interfragmentary gap in Group A was significantly more than Group B (p-Value-0.000). Other parameters like neurosensory deficits, occlusal discrepancies, chewing efficiency, stability of fractured fragments and post-operative complications in terms of swelling, hardware exposure, radiolucency surrounding screw and wound dehiscence did not show any statistically significant difference.
UNASSIGNED: The obtained results showed that both lag screws and Herbert cannulated bone screws fulfill the treatment goals of adequate reduction, fixation and stabilization of oblique mandibular fractures. Herbert screws have shown to have better results in terms of interfragmentary gap reduction as compared to lag screws.

The development of biomaterials in recent years has made it possible to broaden their use in the surgical field. Although iliac crest bone graft harvesting currently remains the gold standard as an autograft, the properties of hydroxyapatite bone substitutes appear to be beneficial. The first fundamental step to consider is the safety of using these devices. The purpose of this retrospective cohort study is to consider all the adverse events observed in our population and assess their relationships with the bone substitute device. The population analyzed consisted of patients undergoing trauma osteosynthesis with at least one implanted porous hydroxyapatite device. We considered a court of 114 patients treated at \"Azienda Ospedaliera Universitaria di Ferrara-U.O. di Ortopedia e Traumatologia\" in the period from January 2015 to December 2022. Upon analyzing our population, no adverse events related to the device emerged. Taking into consideration different study groups from other National Hospital Centers, no critical issues were detected except for three cases of extrusion of the biomaterial. It is necessary to clarify that bone substitutes cannot replace compliance with the correct principles linked to the biomechanics of osteosynthesis. This report outlines a safety profile for the use of these devices as bone substitutes in trauma orthopedic surgery.

UNASSIGNED: There is no consensus whether the primary surgical method should be open reduction and internal fixation (ORIF) or primary arthrodesis (PA) for Lisfranc injuries. The aim of our randomized controlled trial was to compare ORIF and PA for displaced Lisfranc injuries.
UNASSIGNED: This study was a national multicenter randomized controlled trial. Altogether 43 displaced Lisfranc injuries were enrolled in this trial. The primary outcome measure was Visual Analogue Scale Foot and Ankle (VAS-FA) at a 24-months follow-up. The secondary outcome measures were VAS-FA pain, function, and other complaints subscales and the American Orthopaedic Foot & Ankle Society (AOFAS) Midfoot Scale. All outcomes were measured at 6, 12, and 24 months. We were unable to reach the planned sample size of 60 patients; thus, the study remains underpowered.
UNASSIGNED: The mean VAS-FA Overall score in the ORIF group was 86.5 (95% CI 77.9, 95.1) and 80.1 (95% CI 72.0, 88.1) in the PA group at the 24-month follow-up. We did not find eligible evidence of a difference in VAS-FA Overall scores (mean between-group difference 6.5 [95% CI -5.3, 18.2], Cohen d = 0.100).
UNASSIGNED: We did not find evidence of a difference in VAS-FA between ORIF and PA in patients with displaced Lisfranc injuries, and thus both are viable options for the initial surgical method. The trial is underpowered; however, the data may be included in a meta-analysis of similarly designed randomized controlled trials.ClinicalTrials.gov identifier: NCT02953067 24 October 2016.

BACKGROUND: Proximal humerus fracture (PHF) is a risk factor for 1-year mortality. This study aimed to determine if surgery is associated with lower mortality compared to nonoperative treatment following PHF in older patients.
METHODS: This retrospective cohort study used the Medicare Limited Data set. Patients aged 65 years and older with a PHF diagnosis in 2017-2020 were included. Treatment was classified as nonoperative, open reduction internal fixation (ORIF), total shoulder arthroplasty (TSA), or hemiarthroplasty. Multivariable logistic regression models examined (a) predictors of treatment type and (b) the association of treatment type with 1-year mortality, adjusting for patient demographics, comorbidities, frailty, and fracture severity among other variables. A subgroup analysis examined how the relationship between treatment type and 1-year mortality varied based on fracture severity. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) are reported.
RESULTS: In total, 49,072 patients were included (mean age = 76.6 years, 82.3% female). Most were treated nonoperatively (77.5%), 10.9% underwent ORIF, 10.6% underwent TSA, and 1.0% underwent hemiarthroplasty. Examples of factors associated with receipt of operative (versus nonoperative treatment) included worse fracture severity and lower frailty. The 1-year mortality rate after the initial PHF diagnosis was 11.0% for the nonoperative group, 4.0% for ORIF, 5.2% for TSA, and 6.0% for hemiarthroplasty. Compared to nonoperative treatment, ORIF (aOR 0.55; 95% CI [0.47, 0.64]; P < .001) and TSA (aOR 0.59; 95% CI [0.50, 0.68]; P < .001) were associated with decreased odds of 1-year mortality. In the subgroup analysis, ORIF and TSA were associated with a lower 1-year mortality risk for 2-part and 3-/4-part fractures.
CONCLUSIONS: Compared to nonoperative treatment, surgery (particularly TSA and ORIF) was associated with a decreased odds of 1-year mortality. This relationship remained significant for 2-part and 3-/4-part fractures after stratifying by fracture severity.

BACKGROUND: Traditionally, early surgical management of Lisfranc injuries with transarticular screws (TAS) was deemed to be the optimal treatment. However, concerns of potential iatrogenic articular cartilage disruption has led to discrepancies in opinion amongst surgeons, with many surgeons now utilizing dorsal bridge plates (DBP) for ORIF of Lisfranc injuries.
OBJECTIVE: This study sought to investigate the clinical outcomes at medium-term follow-up of consecutive patients in our institution who underwent ORIF with DBP for Lisfranc injuries.
METHODS: All consecutive patients who underwent ORIF with DBPs for Lisfranc injuries were identified. Outcomes of interest included; visual analogue scale (VAS), functional foot index (FFI), American Orthopaedic Foot & Ankle Surgeons (AOFAS) hindfoot scores, and complications.
RESULTS: Overall, 37 consecutive patients (24 males) with a mean age of 34.8 ± 13.0 years underwent ORIF with DBPs for lisfranc injuries. After a mean 48.3 ± 28.7 months, the mean reported AOFAS and FFI scores were 77.4 ± 23.8 and 31.9 ± 32.7 respectively, with satisfactory reported pain scores as measured by VAS post-operatively at rest and whilst walking (2.2 ± 2.5 and 3.1 ± 2.6 respectively). The reported satisfaction rate was 86.5% (32/37). Overall, 25 patients (67.6%) had subsequent removal of metal or were listed for same, 88% (22/25) of whom did so electively in the absence of broken screws or infection.
CONCLUSIONS: This study found that the use of Dorsal Bridge Plates for Open Reduction and Internal Fixation of Lisfranc Injuries resulted in satisfactory functional outcomes, high rates of patient-reported satisfaction and a low complication rate at medium-term follow-up.
METHODS: Level IV; Retrospective Series of Consecutive Patients.

BACKGROUND: The purpose of this study is to evaluate whether using a Fracture Healing Patch (FHP) device that generates pulsed electromagnetic fields (PEMF), applied at the fracture site immediately after open reduction and internal fixation surgery, can accelerate healing of acute distal radius fractures.
METHODS: In a prospective, double-blind, randomized, and sham-controlled study, thirty-two patients with DRFs treated with ORIF were included. Patients were allocated to a PEMF (active) group (n = 15) or a control (sham) group (n = 17). All patients were assessed with regard to functional Patient-Rated Wrist Evaluation (PRWE), SF12, and radiological union outcomes (X-rays and computed tomography (CT) scans) at 2, 4, 6, and 12 weeks postoperatively.
RESULTS: Patients treated with the FHP demonstrated significantly bone bridging at 4 weeks as assessed by CT (70% vs 54%, p = 0.05). Mean grip strength in the active group was significantly higher as compared to control (16 ± 9 kg vs 7 ± 3.5 kg, respectively, p = 0. 02). The function subscale of the PRWE was significantly better in PEMF-treated group at 6 weeks after surgery (27.2 VS 35.5, p = 0.04). No statistically significant differences were found in SF12.
CONCLUSIONS: PEMF application after ORIF of DRFs is safe, may accelerate bone healing which could lead to an earlier return to daily life activities and work.

Periprosthetic fractures following total knee arthroplasty are a quite uncommon traumatic lesion that often are present in elderly patients with osteoporosis and comorbidities. The most common periprosthetic fracture affects the distal femur. The main internal fixation techniques are ORIF with a locking plate and retrograde intramedullary nailing. In the present study, we report the medium-long term results in 12 patients with a distal femoral periprosthetic fracture stabilized with a locking plate. We reviewed 12 patients affected by a periprosthetic distal femur fracture surgically treated between 2010 and 2016 by ORIF using a locking compression plate after an average follow-up of 5.75 years. The average age of the patients at diagnosis was 78 years. The mean interval time between knee arthroplasty and distal femoral fracture was 8.25 years. Clinical results were assessed using the WOMAC score, while radiographic results according to Beals and Tower\'s criteria. All fractures of our series were type II according to the Rorabeck and Taylor classification. At follow-up, the WOMAC score ranged from 40.5 to 76.5 points (average 53.92). Radiographic results, according to Beals and Tower\'s criteria, were excellent in 5 patients and good in 7. All patients returned to their previous daily activities. We believe that reduction and internal fixation with a locking plate is a surgical option of treatment that provides satisfactory clinical and radiological results in Rorabeck type II periprosthetic distal femoral fractures.
