Background: Tibial plateau fractures (TPFs) are complex injuries often leading to long-term complications such as knee instability, limited range of motion, and osteoarthritis. Accurate diagnostic evaluations combining subjective and objective assessments are essential for identifying functional limitations, guiding rehabilitation, and improving recovery outcomes. This study examines the role of diagnostic predictors in differentiating recovery trajectories in two groups of patients treated for closed TPFs by open reduction and internal fixation (ORIF), comparing patients with less severe fractures and patients with more severe fractures (BCFs). Methods: A consecutive series of patients with a diagnosis of TPFs treated by ORIF at our institution between 2009 and 2016 were analyzed in this retrospective study. All injured patients were divided according to the Schatzker classification into two groups: mono-condylar (MCF) and bi-condylar (BCF) fracture patient groups. Diagnostic evaluations included patient-reported outcome measures (PROMs) such as KOOS, IKDC, and AKSS, alongside objective assessments of functional recovery using dynamometers, force platform tests (single-leg stance and squat jump variations), and measurements of active range of motion (AROM). Results: A total of 28 patients were included: 17 in the MCF patient group (Schatzker: 12 II; 5 III; 0 IV) and 11 in the BCF patient group (Schatzker: 6 V; 5 VI). Patients with less severe MCFs exhibited significantly better recovery outcomes, including higher KOOS (86.0 vs. 64.6, p = 0.04), IKDC (80.3 vs. 64.6, p = 0.04), and AKSS (95.3 vs. 70.5, p = 0.02) scores. They also demonstrated greater knee flexion (122.8° vs. 105.5°, p = 0.04) and faster neuromuscular recovery, as evidenced by higher rates of force development (RFD) during dynamic performance tests. Conversely, patients with more severe BCFs showed lower RFD values, indicating slower recovery and greater rehabilitation challenges. Conclusions: Integrating diagnostic tools like PROMs, AROM, and neuromuscular performance tests provides valuable insights into recovery after ORIF for TPFs. Fracture severity significantly impacts functional recovery patients with MCFs showing better outcomes and faster neuromuscular recovery, while subjects with BCFs require a longer rehabilitation treatment focusing on neuromuscular re-education and soft tissue recovery.

Metallic biomaterials are prevalent in medical applications. In the treatment of mandibular fractures, the use of metallic biomaterials makes it possible to recover the ability to bite and partially recover speech through preventing ankylosis of the temporomandibular joints, the formation of pseudoarthritic joints, and the consolidation of reduced bones. This article presents the concept of a triaxial plate for osteosynthesis of basal fractures of the mandibular condyle, which are very common fractures in humans. Approximately half of patients with such fractures have wide (squat) condylar processes, which allows for the use of as many as three straight plates. However, installing three plates is quite troublesome, and the use of a single and transversely reinforced plate would facilitate treatment. This study proposes a plate with three reinforcements running along three divergent axes. The plate is fixed to the bone fragments with 11 screws. This concept for the treatment of basal fractures allows patients to quickly recover their primary system functions due to rigid fixation through the use of short (4 mm) screws, as there is no trauma to the medial pterygoid muscle and the mandible canal contents and no intermaxillary immobilization.

A major controversy in maxillofacial surgery practice is the management of mandibular condylar fractures (CFs). The debate revolves around open versus closed treatment, rather than identifying clear indications whereby open reduction and internal fixation (ORIF) is the most viable treatment modality. Opinions regarding precise indications for ORIF remain unclear and non-uniform. We aimed to refocus the debate regarding the optimal treatment for CFs by identifying the recent indications for ORIF in the literature and assessing the quality of the existing evidence for each indication. This systematic review searched Medline, Embase and the Cochrane Central Register of Controlled Trials for eligible studies. The included studies consisted of articles from the past 15 years involving patients with any type of CF who underwent ORIF based on specified indications. From 4711 papers, 100 studies were included. In these, 121 indications were identified. The most cited indications for ORIF were those proposed by Zide and Kent, namely displacement/angulation ≥10° and ramus height shortening of ≥2 mm. Evidence supporting these indications is weak, relying mainly on expert opinion rather than robust data, with a focus on treatment comparisons. Clear, evidence-based cutoffs regarding when ORIF is the only viable treatment option are needed for a consensus. Full article

(1) Background: Condylar fracture healing pattern classification in children and adolescents is primarily based on the radiological assessment of condylar morphology; however, recent studies showed the presence of a poor correlation between post-treatment radiological findings and clinical temporomandibular joint (TMJ) dysfunction. The present case series aimed to correlate the condylar morphology, shape, and trabecular bone density with the skeletal asymmetry and the clinical recovery of two growing patients with unilateral condylar fractures undergoing orthopedic treatment with the Balters Bionator appliance. (2) Methods: Pre- and post-treatment (12 months) cone-beam computed tomography (CBCT) scans of two growing patients with unilateral condylar fracture were retrieved; both patients were treated with the Balters Bionator appliance for one year. Morphological evaluation of the condylar healing pattern was carried out on CBCT reconstructions of the mandible. Condylar remodeling and skeletal asymmetry were assessed through linear measurements performed on pre- and post-treatment CBCT scans; then, fractal analysis (FA) was employed to assess the condylar trabecular bone density on orthopantomographies (OPTs). Clinical and TMJ functional evaluation were retrieved from patients’ records from before and at the end of the treatment (12 months). (3) Results: Conservative treatment of condylar fractures in growing patients led to an increased bone density of the condylar heads, regardless of the post-treatment size and morphology of the injured condyles. Patient one presented an unchanged condylar morphology on the affected side, while patient two’s condyle was slightly spherical. The qualitative results were confirmed by quantitative measurements on CBCTs. The radiological healing patterns were associated with slightly different functional outcomes. Both patients also exhibited an improvement in skeletal asymmetry and TMJ function. (4) Conclusions: According to the findings in the present study, the condylar remodeling and bone apposition after conservative treatment of condylar fractures in growing patients can exhibit different radiological and functional outcomes. Indeed, an unchanged morphology of the condylar head is more likely to determine a physiological TMJ recovery. Full article

Background: Distal humerus physeal separation (DHPS) presents a rare injury type in young children often associated with misdiagnosis and delayed treatment. The aim of this study was to summarize all the available current evidence regarding the management and outcome of DHPS and determine the incidence of complications and particularly the cubitus varus deformity and avascular necrosis of the trochlea. Methods: A systematic review was conducted under the PRISMA guidelines. Medline/Pubmed, Scopus, Web of Science, and Cochrane were searched for studies dealing with children suffering from traumatic DHPS. Results: Twelve studies with a total of 257 children with DHPS were included for analysis. The mean age was 16.8 months (range: 0.1–46 months) with a mean follow-up of 37 months (range: 0.5–516 months). Non-accidental trauma was reported in 17.2% and misdiagnosis at initial assessment in 7.8%. Closed reduction and percutaneous pinning (CRPP) was the treatment of choice in 54.4%, open reduction and percutaneous pinning (ORPP) in 26.5%, closed reduction and cast immobilization (CR+cast) in 10.9%, and cast immobilization without reduction in 8.2%. The average range of extension–flexion arc was 2.1° to 127.8° (range: −10–140°). The mean Bauman’s angle was 72.4° (range: 66–79°), the mean shaft–condylar angle was 43.8° (range: 25–59°), the mean humeral length was 21.9 cm (range: 15.5–25.8 cm), and the mean carrying angle was 5.1° (range: 16° varus–19° valgus). According to Flynn’s criteria, 85.2% of cases were classified as excellent or good. The ORPP technique was associated with excellent results, while the CR+cast treatment combination was correlated with the poorest outcome (p = 0.001). Cubitus varus occurred in 18.9% (34 cases) and was highly correlated with CR+cast or cast immobilization alone without fracture reduction (p = 0.014). Avascular necrosis of the trochlea was found in 3.9% (7 cases) and was mainly apparent after cast immobilization without reduction (p < 0.001). Conclusions: Post-traumatic cubitus varus deformity may be encountered in approximately one-fifth of young children with DHPS. Surgical intervention with either CRPP or ORPP is the most effective treatment approach, leading to superior functional outcome and a lower complication rate. Full article

Background: The optimal treatment decision for pediatric condylar fractures is influenced by various factors, including the child’s age, fracture type, degree of displacement, and the presence of concomitant injuries. While non-surgical treatments are generally preferred due to high remodeling capacity in children, there remains a lack of comprehensive research comparing the long-term outcomes of open reduction internal fixation (ORIF) versus conservative management. Methods: Retrospective analysis of medical records of 71 pediatric patients (aged 0–18 years) treated for condylar fractures at the Department of Oral and Maxillofacial Surgery, Rambam Healthcare Campus, between 2010 and 2020 was completed. Gender, age, admission date, cause of injury, treatment methods, length of hospital stay, follow-up duration, and follow-up status were studied to help determine association with modality of treatment and complications. Results: No statistically significant differences were seen in complication rates across different age groups, genders, trauma etiologies, fracture sites (head/neck/base), laterality of fractures, nor was there an impact on choice of surgical vs. conservative intervention. Similar length of hospital stay was observed, even in cases with delayed surgical intervention. There was also no statistical significance of injury distribution based on socioeconomic standing. Conclusions: Our research showed similar rates of complications in both surgically treated and conservatively treated cases. This solidifies the importance of practitioner experience, as well as comprehensive anamnesis to help caretakers most effectively determine the optimal treatment for each patient. As the surgical study group is substantially smaller than the conservatively treated group, large-scale prospective studies with extended follow-up will more conclusively help solidify results and establish guidelines.

Background/Aim: The purpose of this study was to reproduce a lateral fall using a computer simulation model and to clarify the circumstances of mandible fracture caused by a lateral impact. Material and methods: Fall scenarios were reconstructed using a computer simulation with finite element models. The fall condition was set as a fall from the head direction, which would cause facial injuries. In each simulation, the effective plastic strain of the mandible and its site were determined. Analysis of variance was performed to determine which factors had a significant effect on the maximum effective plastic strain of the mandible. Results: Significant differences with p-values less than 0.001 were found for the following factors: pitch angle, lateral bending angle, impact object, combination of pitch angle and lateral bending angle, and combination of pitch angle and impact object. In most cases with higher values of effective plastic strain, which can cause mandibular fractures, the site was found at the condylar process or mandibular angle of the attacked side. Conclusion: If the patient falls laterally and their face makes contact with a protruding object, medical professionals can predict fractures of the upper part of the mandibular angle and the condyle of the affected side.

This study compares the compression force of cortical screws used in lag fashion with partially threaded cannulated screws and fully threaded headless cannulated screws as fixation methods for humeral condylar fractures in dogs. Cadavers of eleven dogs weighing an average of 10.99 ± 2.51 kg (6.1–14.4 kg) were used. The humeri were subjected to simulated fracture by performing an osteotomy at the trochlea of humerus and classified into three groups: Group 1 applied a 3.0 mm cortical screw applied in a lag fashion, Group 2 applied a 3.0 mm partially threaded cannulated screw, and Group 3 applied a 3.5 mm fully threaded headless cannulated screw. The samples were then placed in a material testing machine, and a compression force was applied vertically to the lateral condyle until failure. There were statistically significant differences in failure load between the groups (p = 0.009). The maximum failure load in Group 3 was significantly higher than in Group 2 (p = 0.014), while there were no statistically significant differences between Group 1 and Group 2) or between Group 1 and Group 3. Partially threaded cannulated screws and fully threaded headless cannulated screws can be alternatives to traditional stabilization methods, offering simpler procedures and additional advantages.

Background: During the routine removal of osteosynthesis materials after surgical treatment (ORIF) of condylar head fractures (CHFs), as performed at our clinic, localised and sometimes pronounced intra-articular scarring were observed quite regularly. This prospective study therefore investigates the causes of intra-articular scarring and its impact on functionality after surgical treatment (ORIF) of condylar head fractures (CHFs). Methods: Moreover, 80/98 patients with 96/114 CHFs (ORIF between 2014 and 2024) were evaluated when performing hardware removal. Statistical analysis used logistic regression and sign tests. Results: Postoperative scarring was seen in 72/96 cases (75%), either localised (n = 54; 56%) or pronounced (n = 18; 19%). Scarring correlated with limitations of laterotrusion for pronounced scarring (p = 0.016; OR = 6.806; 95% CI [1.422, 32.570]; large effect size) and with limitations of mediotrusion for localised scarring (p = 0.013; OR = 0.236; 95% CI [0.076, 0.734]; very small effect size). Factors favouring localised scarring were reduced ipsilateral dental support (p = 0.022; OR = 3.36; 95% CI [1.191, 9.459]; medium effect size) and major fragmentation (p = 0.029; OR = 3.182; 95% CI [1.123, 9.013]; medium effect size). However, there was no correlation between scarring and types (screws w/wo microplates) or number of osteosynthesis materials. Pronounced scarring showed a significantly higher risk for osseous degenerative complications (p = 0.041; OR = 4.171; CI [1.058, 16.452]; medium effect size). Conclusions: Intra-articular scarring after ORIF of CHFs poses a risk for functional limitations and osseous degenerative changes. Early adhesiolysis during the removal of hardware seems favourable for functional outcomes after CHFs. Full article

Background/Objectives: Supracondylar humerus fractures (SCHFs) are the most common pediatric elbow injuries and often require surgical intervention. Despite guidelines, optimal timing for surgical management, particularly for cases without neurovascular compromise, remains unclear. This study evaluates the influence of surgical timing on short-term outcomes, focusing on fracture reduction quality and surgical parameters. Methods: In total, 62 pediatric patients who had been treated for Gartland type II and III SCHF between 2018 and 2023 were retrospectively assessed. Patients were grouped based on time of admission (morning, afternoon, early evening, and night shifts) and time to surgery (<12 h vs. >12 h). Primary outcomes included immediate radiological reduction, assessed via the Baumann’s angle (BA) and shaft-condylar angle (SCA). Secondary outcomes encompassed surgery duration and radiation exposure. Statistical analyses used ANOVA and chi-square tests, with p < 0.05 considered significant. Results: No significant differences were observed in BA (p = 0.84) or SCA (p = 0.79) between early and delayed surgical groups. Similarly, surgical timing (shift or delay >12 h) did not significantly affect surgery duration (p = 0.92) or radiation exposure (p = 0.12). The complication rate was 6.45%. Conclusions: Surgical timing, including delays beyond 12 h, does not adversely affect short-term outcomes in SCHFs. However, after-hours procedures may pose practical challenges, emphasizing the importance of surgeon experience and institutional protocols. Larger prospective studies are warranted to validate these findings and examine them in the long term. Full article

Background/Objectives: Occipital condyle fractures (OCFs) can be seen in around 4–19% of patients who suffer from cervical spine trauma. Anderson and Montesano system type III OCFs, which are avulsion fractures, are potentially unstable and operative. This study evaluates the management of type III OCFs at our institution over a 22-year period. Methods: This retrospective study reviewed all cases of type III OCFs at our institution from July 2001 to March 2023, identified via imaging reports. Using the in-house radiology imaging informatics system “Doris” (Dig Our Radiology Information System), reports containing the terms subluxation, avulsion, unstable, or type 3/III with occipital condyle, occipital condylar, occipital fx, or occipital fracture were collected. We also searched for Montesano type III/3 fracture. Electronic medical records were used to collect clinical and demographic data. Patients evaluated by the neurosurgical team with at least 1 month of follow-up were included in the analysis. Results: A total of 563 patients were identified with type III OCFs. A total of 56 patients met the inclusion criteria. The majority (91%, 51/56) were treated conservatively with cervical orthosis. A small subset (8.9%, 5/56) underwent occipito-cervical fusion. Three had concomitant unstable C1 fractures, while the other two had significant coronal deformity associated with their type III OCF. Conclusions: At our institution, type III OCFs are predominantly managed with cervical orthosis. Only those with an associated malalignment of the occipito-cervical joint underwent fusion. These findings suggest that most type III OCFs can be treated conservatively with orthosis once stability is confirmed with an upright radiograph. Full article

Background: Mandibular condylar fractures are among the most common fractures of the facial skeleton, and their surgical management remains a topic of considerable debate in maxillofacial trauma surgery. Numerous studies in the literature internationally have explored optimal treatment approaches, with a growing preference for open reduction and internal fixation (ORIF). While conservative treatment has traditionally been the standard for intra-articular fractures, recent research suggests that ORIF may also be appropriate for selected cases of these fractures. Methods: This study presents a 14-year review (2009–2023) of the authors’ experience in the surgical management of intra-articular condylar fractures. Data were collected on surgical techniques, early and late complications, clinical and radiological outcomes, and comparisons with conservative treatment. Results: The analysis included evaluations of both short-term and long-term outcomes following ORIF, identifying specific scenarios where ORIF demonstrated advantages over conservative management. Clinical and radiographic assessments provided valuable insights into patient recovery and functional outcomes, while complication rates were documented for both treatment methods. Conclusions: Findings indicate that ORIF can be a beneficial treatment option for intra-articular condylar fractures in select patient groups, offering improved outcomes in cases where conservative treatment may be insufficient. However, conservative management remains a valid approach when surgical risks exceed potential benefits. This study adds to the ongoing discussion, supporting a tailored approach that considers individual patient factors when choosing between ORIF and conservative treatment. Full article

This narrative review evaluates the literature on the management of mandibular condyle fractures in growing patients. It aims to illustrate some fundamental biological principles and to offer a series of considerations applicable to clinical practice. The discussion is based on 116 papers published in PubMed and two relevant textbooks. Condylar fractures may be overlooked, especially in pre-scholar children, where compliance is usually reduced. However, these injuries can have disabling sequelae such as ankyloses, facial deformities, malocclusion, and chronic pain in some patients if not diagnosed and managed correctly. Due to their significance, mandibular condyle fractures in children are a subject of considerable clinical interest. As of today, there is consensus about their treatment. Four management options are available: expectative (analgesia, soft food and follow-up), functional protocols (guiding elastics, orthodontic appliances and exercises), maxillomandibular fixation (MMF), and open reduction and internal fixation (ORIF). Nondisplaced and minimally displaced fractures should be treated expectantly; severely displaced non-comminuted fractures can be safely operated on if the expertise is available, even in patients with deciduous dentition. Moderately displaced fractures can be managed with functional protocols or operatively, depending on the background and know-how of the specialist. Functional protocols can achieve good outcomes, especially in patients with deciduous dentition. MMF should be foregone in children due to its many drawbacks. Full article

Background: Mandibular condyle fractures in pediatric patients can lead to crippling sequelae such as ankylosis, pain and facial deformity if not managed properly. However, there is no consensus on the best approach for treating these fractures in children. Objective: This study aimed to describe the management of mandibular condyle fractures in growing patients across 14 maxillofacial departments worldwide. Methods: A retrospective multicenter study was conducted on children and adolescents aged 0 to 16 who had at least one mandibular condyle fracture. This study included patients who underwent expectant, closed, or open management and were treated over an 11-year period. Results: 180 patients had at least one mandibular condyle fracture, and 37 had a second condylar fracture. One hundred sixteen patients (65%) were males, and 64 (35%) were females (ratio 1.8:1). An expectant strategy was chosen in 51 (28%) patients, a closed treatment—stand-alone maxillomandibular fixation (MMF)—in 47 (26%), and open reduction and internal fixation (ORIF) was performed in 82 (46%) patients. The management varied significantly between the different departments (p < 0.0001). Significant differences were also identified between the fracture type (non-displaced, displaced or comminuted) and the management of the 180 patients with a single condylar fracture. Out of 50 non-displaced fractures, only 3 (6%) had ORIF, 25 (50%) had expectant management, and 22 (44%) had MMF. Out of 129 displaced fractures, 79 (62%) had ORIF, 25 (19%) had a soft diet, and 25 (19%) had MMF. Conclusions: Expectative management, MMF, and ORIF were all effective in treating pediatric mandibular condyle fractures, with a low incidence of complications and asymmetry. Full article

Study Design: A retrospective study. Objective: This retrospective study aims to analyze the results of Le Fort I fracture treatment, with a focus on addressing malocclusion related to the fractures. Methods: The study included 43 patients diagnosed with Le Fort I fractures who underwent open reduction and internal fixation. Demographic data, causes of trauma, accompanying facial bone fractures, treatment methods, and complications were analyzed. Fisher’s exact test was employed to assess the association between fractures and malocclusion. Results: Postoperative complications included occlusal disorder (6 cases), sensory disturbance (4 cases), and facial deformation (6 cases). Condylar fractures showed a statistically significant association with occlusal disorders (p = 0.044). Surgeon variability did not significantly impact occlusal outcomes (p = 0.25). Conclusions: Proper management of Le Fort I fractures requires a thorough understanding of surgical principles and consideration of concomitant fractures. Achieving anatomical reduction based on occlusion is crucial for successful outcomes, and additional Le Fort I osteotomy may be considered in challenging cases. Full article
