A Case Report of U-Type Sacral Fracture After Chiropractic Adjustment.

CASE: A U-type sacral fracture, or spinopelvic dissociation, resulting from chiropractic manipulation has not been described in the medical literature. This report presents the case of a 74-year-old male patient who sustained a U-type sacral fracture after drop-table chiropractic manipulation. CONCLUSION: Our case demonstrates that chiropractic manipulative therapy involving the commonly used drop-table can cause severe injury. The patient's course was complicated by a delay in diagnosis and a prolonged hospital stay. Orthopaedic surgeons should have a high degree of suspicion for spinopelvic dissociation in the setting of bilateral sacral fractures. One year after injury, with conservative management, the patient returned to baseline function with mild residual neuropathy.

Wide-awake local anesthesia and no tourniquet (WALANT) in upper limb fractures.

Wide-awake local anesthesia and no tourniquet (WALANT), first used for hand surgery, has been sparingly described for use in fracture fixation of the upper limb. We present our experience using this technique. 26 patients with upper limb fractures (3 distal radius, 6 radial shaft, 11 ulnar shaft, and 6 olecranon fractures) were operated on using WALANT by three orthopedic surgeons. We used 35-40ml of 2% Lignocaine with 1:80000 Adrenaline(7mg/kg) diluted with normal saline. Numeric Pain Rating (NPR) scoring was done during injection and per-operatively, and the Likert scale was used for the surgeon's satisfaction. The average NPR score was reported as 0.65 (1-3) during injection and 0.15 (0-2) preoperatively. All three surgeons reported excellent satisfaction in all the cases operated on. No complication occurred due to anesthesia. WALANT is a much simpler option and can be safely used in place of general anesthesia or regional blocks for fixation of fractures of the upper limb, with added advantages of no need for a tourniquet and better intraoperative assessment of fracture fixation.

[Research progress in separation surgery combined with stereotactic radiotherapy of spinal metastases].

With the continuous improvement of cancer treatment, the survival of patients with spinal metastases has been significantly prolonged. Currently, the treatment of spinal metastases presents a trend of multi-mode. Clinical surgical methods include vertebral tumor resecting spinal canal decompression and internal fixation surgery, separation surgery, minimally invasive surgery and percutaneous ablation technology, etc. Radiotherapy techniques include traditional external radiation therapy, stereotactic radiotherapy and brachytherapy, etc. The risk of vertebral tumor resecting spinal canal decompression and internal fixation surgery, and the incidence of intraoperative and postoperative complications is high. The extension of postoperative recovery period may lead to delay of follow-up radiotherapy and other medical treatment, which has a serious impact on patients' survival and treatment confidence. However, the precision of traditional external radiation therapy is not high, and the limitation of tolerance of spinal cord makes it difficult to achieve the goal of controlling insensitive tumor. With the development of radiotherapy and surgical technology, stereotactic radiotherapy with higher accuracy and separation surgery with smaller surgical strike have become the focus of many clinical experts at present. This article reviews the progress of Hybrid treatment of separation surgery combined with stereotactic radiotherapy.

Depth camera-based model for studying the effects of muscle loading on distal radius fracture healing.

BACKGROUND: Distal radius fractures (DRFs) treated with volar locking plates (VLPs) allows early rehabilitation exercises favourable to fracture recovery. However, the role of rehabilitation exercises induced muscle forces on the biomechanical microenvironment at the fracture site remains to be fully explored. The purpose of this study is to investigate the effects of muscle forces on DRF healing by developing a depth camera-based fracture healing model. METHOD: First, the rehabilitation-related hand motions were captured by a depth camera system. A macro-musculoskeletal model is then developed to analyse the data captured by the system for estimating hand muscle and joint reaction forces which are used as inputs for our previously developed DRF model to predict the tissue differentiation patterns at the fracture site. Finally, the effect of different wrist motions (e.g., from 60° of extension to 60° of flexion) on the DRF healing outcomes will be studied. RESULTS: Muscle and joint reaction forces in hands which are highly dependent on hand motions could significantly affect DRF healing through imposed compressive and bending forces at the fracture site. There is an optimal range of wrist motion (i.e., between 40° of extension and 40° of flexion) which could promote mechanical stimuli governed healing while mitigating the risk of bony non-union due to excessive movement at the fracture site. CONCLUSION: The developed depth camera-based fracture healing model can accurately predict the influence of muscle loading induced by rehabilitation exercises in distal radius fracture healing outcomes. The outcomes from this study could potentially assist osteopathic surgeons in designing effective post-operative rehabilitation strategies for DRF patients.

Elastic Stable Intramedullary Nailing Improves Fracture Healing and Mobility in Children with Femoral Fractures.

Objective: To explore the application value and safety of elastic stable intramedullary nailing (ESIN) in pediatric femoral fractures (FFs), providing more reliable safety for the treatment of FFs in the future. Methods: This study selected 60 cases of pediatric FFs who completed fracture treatment in our hospital between March 2014 and January 2023, with 32 cases undergoing ESIN fixation included in the research group (RG) and another 28 cases receiving plate internal fixation assigned to the control group (CG). The operative time (OT), intraoperative blood loss (IBL), incision length, fracture healing time, fixator removal time, weight-bearing time, and hospital length of stay (HLOS) of the two groups were counted, and the pain of the children was evaluated by the Visual Analogue Scale (VAS). The clinical efficacy and complication rate were recorded, and the hip and knee functions before and after treatment were evaluated by the Hospital for Special Surgery (HSS) score. After the completion of treatment, the child's family was surveyed about their satisfaction with the treatment. Results: The research group had less OT, IBL, and incision length, as well as shorter fracture healing time, fixator removal time, weight-bearing time, and HLOS than the control group (P < .05), with markedly lower VAS scores at 12h-48h postoperatively (P < .05). In addition, the research group demonstrated an obviously higher overall response rate (96.88%) and a lower complication rate (15.63%) than the control group (P < .05). Furthermore, HSS scores and treatment satisfaction were higher in the research group than in the control group (P < .05). Conclusions: ESIN is a highly effective treatment for pediatric femoral fractures, leading to accelerated fracture healing, improved mobility, and exhibiting high clinical application value.

Ruptured subclavian artery pseudoaneurysm following a shoulder massage on a background of clavicle non-union.

We present an unusual case of ruptured subclavian artery pseudoaneurysm following hydrotherapy and shoulder massage session on a background of clavicle non-union.Following a clavicle fracture 16 years ago, which was managed conservatively, a woman in her 30s presents over a decade later with a ruptured subclavian artery pseudoaneurysm.The original midshaft clavicle fracture was sustained 16 years ago. Conservative management was agreed, and she was discharged. Six years ago, she developed a small subclavian artery pseudoaneurysm which was kept under surveillance for 12 months with no active intervention required.Over the following years, she continued to have intermittent shoulder girdle discomfort and neuropathic symptoms. On this presentation, after a sports massage, she presented with rapid-onset supraclavicular and axillary swelling. This was diagnosed as a ruptured subclavian artery pseudoaneurysm and was treated with emergency radiological-guided stenting and subsequent internal fixation of the clavicle non-union.The patient then attended regular orthopaedic and vascular follow-up to ensure her clavicle fracture unites and the graft remains patent.We discuss the case presentation and management of this unusual injury.

Novel Standalone Motion-Sparing Pelvic Fixation Prevents Short-Term Insufficiency Fractures After Midsacrectomies Without Sacrificing Normal, Mobile Lumbar Segments Traditionally Used for Stabilization.

BACKGROUND AND OBJECTIVES: Sacrectomy is often the treatment of choice to provide the greatest chance of progression-free and overall survival for patients with primary malignant bone tumors of the sacrum. After midsacrectomy, the stability of the sacropelvic interface is diminished, resulting in insufficiency fractures. Traditional stabilization involves lumbopelvic fixation but subjects normal mobile segments to fusion. The purpose of this study was to determine whether standalone intrapelvic fixation is a safe adjunct to midsacrectomy, avoiding both sacral insufficiency fractures and the morbidity of instrumenting into the mobile spine. METHODS: A retrospective study identified all patients who underwent resection of sacral tumors at 2 comprehensive cancer centers between June 2020 and July 2022. Demographic, tumor-specific, operative characteristics and outcome data were collected. The primary outcome was presence of sacral insufficiency fractures. A retrospective data set of patients undergoing midsacrectomy without hardware placement was collected as a control. RESULTS: Nine patients (5 male, 4 female), median age 59 years, underwent midsacrectomy with concomitant placement of standalone pelvic fixation. No patients developed insufficiency fractures during the 216 days of clinical and 207 days of radiographic follow-up. There were no adverse events attributable to the addition of standalone pelvic fixation. In our historical cohort of partial sacrectomies without stabilization, there were 4/25 patients (16%) with sacral insufficiency fractures. These fractures appeared between 0 and 5 months postoperatively. CONCLUSION: A novel standalone intrapelvic fixation after partial sacrectomy is a safe adjunct to prevent postoperative sacral insufficiency fractures in patients undergoing midsacrectomy for tumor. Such a technique may allow for long-term sacropelvic stability without sacrificing mobile lumbar segments.

Age is Not the Most Important Factor in the Prognosis of Femoral Neck Fracture: An Analysis of Long-Term Clinical Follow-Up.

Objective: The prognosis of femoral neck fractures is affected by factors including age and type of fracture. This study aimed to explore the associations among postsurgical outcomes of internal fixation for femoral neck fracture (healing rate, necrosis rate, and joint function score) and age and type of fracture. Methods: We retrospectively analyzed 297 cases of femoral neck fracture treated with internal fixation between February 2008 and October 2018. The postoperative femoral neck nonunion rate (a measure of healing) and femoral head necrosis rate were determined by x-ray and computed tomography. The Harris hip score (a measure of joint function and pain) was calculated. The effects of age and fracture type on these factors were analyzed. Results: There was no significant difference in the rate of femoral head necrosis and postoperative joint function scores among the different age groups. There was a significant difference in the postoperative rate of femoral head necrosis by Garden (P = .001) and Pauwels (P = .01) fracture types. No significant differences were noted for the Harris hip score for fractures characterized by the Pauwels classification (P = .09). However, the Harris hip scores differed significantly among groups for fractures categorized by the Garden classification (P = .001). Conclusions: Fracture type but not age is closely related to femoral head necrosis and Harris hip score after internal fixation of femoral neck fractures.

Trends in management of adult tarsometatarsal joint injuries in a contemporary Australian context: a nationwide study of claims data over 20 years.

BACKGROUND: Traumatic tarsometatarsal joint (TMTJ) injuries are uncommon, but can cause significant morbidity due to delayed or missed diagnosis. Recent evidence highlights the importance of achieving anatomical reduction via operative management. This study aims to analyse trends in rates of open reduction internal fixation (ORIF) for Lisfranc injuries in Australia according to Nationwide claims data. METHODS: Claims according to the Medicare Benefits Schedule (MBS) on ORIF of traumatic TMTJ injuries were collated for the period from January 2000 to December 2020. Paediatric patients were excluded. Two negative binomial models were utilized to analyse the trends in TMTJ injuries over time after controlling for sex, age group and population changes. Results were absolute and per 100 000 population. RESULTS: 7840 patients underwent TMTJ ORIF over the period studied. There was a mean yearly increase of 12% (P < 0.001). Age group (P < 0.001) and year (P < 0.001) were significant predictors for TMTJ fixation, whilst sex was not (P = 0.48). Patients older than 65 years were noted to have a 53% lower rate of TMTJ ORIF per person, when compared to the reference group of 25-34 year-olds (P < 0.001). Five-year block analysis revealed increases in rate of fixation for all age groups. CONCLUSION: Rates of operative fixation for TMTJ injuries are increasing in Australia. This is likely due to improved diagnostics, understanding of optimal treatment goals, and increased orthopaedic subspecialisation. Further studies with clinical and patient reported outcomes, as well as comparing rates of operative intervention to incidence, will be useful.

Efficacy of Femoral Neck System Fixation vs KHS Femoral Neck Dynamic Compression Locking Plate System in Femoral Neck Fracture.

Background: Femoral neck fracture is acknowledged as one of the common injuries in clinical orthopedics. Our study was aimed at investigating the efficacy of femoral neck fixation vs the KHS dynamic compression locking plate system in the treatment of femoral neck fracture. Methods: This was a prospective study. A toteal of 90 patients with femoral neck fracture who were admitted to The Third Hospital of Hebei Medical University in Shijiazhuang, China from August 2017 to March 2020 were enrolled in our study. The patients were randomly divided into the control group (45 patients allocated to intervention with the novel femoral neck dynamic compression locking plate system) and the study group (45 patients who underwent femoral neck system fixation). Intraoperative blood loss, surgery duration, fracture healing time and related complications in the 2 groups were monitored and evaluated. The recovery of hip joint function at different times in the 2 groups were closely monitored. Results: The 2 groups completed the surgery process, and the incision healed. All patients were followed up for 6 to 8 months, with an average follow-up time of 7.01 ± 0.21 months. Surgery duration, length of hospital stay and fracture healing time in the study group were significantly lower than in the control group (P < .05), while no significant difference was found in intraoperative blood loss between the 2 groups (P > .05). At 1 and 3 months after surgery, hip joint function in the study group was significantly higher than in the control group (P < .05), but 6 months after surgery, there was no significant difference between the 2 groups (P > .05). There were no complications in the study group, whereas 1 patient had a complication in the control group. The total incidence of complications in the study group was lower than in the control group, but the difference was not significant (P > .05). Conclusion: Femoral neck system fixation demonstrated superior efficacy to the KHS femoral neck dynamic compression locking plate system in femoral neck fracture, and is considered as a valid method for wide application.

[Treatmen of distal femoral fracture of Müller type A with homeopathic bidirectional-traction reduction device unite with internal fixation].

OBJECTIVE: To investigate the effect of treatment of Müller A fracture of distal femur with small incision internal fixation assisted by homeopathic bidirectional-traction reduction device. METHODS: From January 2018 to December 2019, 22 patients (14 males and 8 females) with Müller type A distal femoral fractures were treated with homeopathic bidirectional-traction assisted reduction and minimally invasive small incision locking plate internal fixation;The age ranged from 29 to 58 years old with an average of (41.23±7.03) years. The time from injury to operation was 1 to 7 days with an average of (3.41±1.71) days. According to Müller classification, there were 4 cases of type A1, 10 cases of type A2, and 8 cases of type A3. The postoperative knee joint function was evaluated by Schatzker Lambert fracture criterion of distal femur. RESULTS: All the incisions healed in one stage without infection, osteomyelitis and other complications. All the fractures healed without malunion and nonunion. All of 22 patients were followed up for 12 to 18 months with an average of (14.50±2.02) months. The healing time was 3 to 6 months with an average of (4.64±1.14) months. According to Schatzker Lambert criteria for distal femoral fracture, 12 cases were excellent, 6 good, and 4 medium. CONCLUSION: It is an ideal method to treat Müller type A fracture of distal femur with homeopathic bidirectional-traction assisted reduction device and minimally invasive small incision locking plate internal fixation.

Manual Reduction and Plaster External Fixation for the Treatment of Closed Total Talus Dislocation: Case Report and Literature Review.

BACKGROUND: Total dislocation of the talus from all its surrounding joints (talonavicular, tibiotalar, subtalar) is one kind of serious injury of the lower extremity with rare occurrence. It is usually accompanied by fractures of the talus and its periphery, as well as severe soft tissue injury, which is difficult to reset. Complications such as skin necrosis and infection are prone to occur in the early stage, and talus necrosis are prone to occur in the late stage, all of which aggravate disease severity and increase difficulties for its treatment. CASE PRESENTATION: Herein, we reported a case of right talus total dislocation accompanied by medial malleolus fracture and posterior tubercle fracture caused by traffic accident. One hour after injury, the doctor tried to perform manual reduction but failed. Then, we successfully performed manual reduction and plaster external fixation on this patient under anesthesia 6 h after injury, followed by the oral administration of Chinese medicine for 3 months. Twenty months of follow-up investigations revealed that no skin necrosis, talus dislocation, talus necrosis, or other complications occurred; no obvious joint degeneration was observed and the fractures of medial malleolus and talus healed well. MRI of ankle joint indicated the disappearance of ankle effusion caused by injury, and the bone marrow edema had also subsided at talus, medial malleolus, and lateral malleolus and calcaneus. Patient presented with no ligament relaxation, ankle instability, pain, swelling, or functional limitation of the injured limb. AOFAS score reached 100. Daily functions and recreation activities were recovered back to the normal level. CONCLUSION: For patients with closed total dislocation of the talus, fine therapeutic effects can be achieved by early closed manual reduction and plaster external fixation under anesthesia, in combination with oral Chinese herbal medicine afterwards. It is worthy of reference for clinicians.

Surgical management of clavicle fractures in Australia: an analysis of Australian Medicare Benefits Schedule database from 2001 to 2020.

BACKGROUND: There is no consensus on the optimal management of clavicle fractures, with advocates of both operative and non-operative management. The objective of this study is to assess the trends in the management of clavicle fractures in Australia over the past two decades. METHODS: The incidence of surgical fixation of clavicle fractures from 2001 to 2020 was analysed using the Australian Medicare Benefits Schedule database, reflective of operations performed on privately insured patients, thus excluding public patients and compensable cases. An offset term was utilized with data from the Australian Bureau of Statistics to account for population changes over the study period. RESULTS: A total of 17 089 procedures for the management of clavicle fractures were performed from 2001 to 2020. The incidence of operative intervention increased from 1.87 per 100 000 in 2001 to a peak of 6.63 per 100 000 in 2016. An overall increase was seen in males (310%) and females (347%) over the study period, as well as across all age groups. A greater proportion of operative interventions was performed on males (n = 14 075, 82%) than females (n = 3014, 18%, P < 0.001). The greatest increase in intervention was noted in those aged 65 or older (14% increase per year, 95% CI 11%-17%, P < 0.05). In 2020, the incidence of operative intervention decreased to a level last seen in 2013. CONCLUSIONS: The incidence of operative interventions for clavicle fractures has increased in Australia over the 20-year study period. This increase is in keeping with recent evidence suggesting several advantages when displaced mid-shaft clavicle fractures are operatively managed.

Successful Revision with INTERTAN for a Blade Cut Through in PFNA Fixation: A Case Report.

BACKGROUND: Implant cut-out or cut-through remains a common cause of cephalomedullary nail failure and patient morbidity following surgical treatment of intertrochanteric femur fractures. In patients not suitable for conversion to total hip arthroplasty, which can involve long operation times and substantial blood loss, as well as a higher risk of periprosthetic fracture and dislocation postoperatively, revision with another internal fixation is an alternative option. If the femoral head can be preserved as much as possible to avoid eventual joint replacement while the internal fixation failure is solved, the quality of life of patients will be significantly improved. CASE PRESENTATION: This current case describes a successful clinical use of a salvage procedure that allows the surgeon to avoid joint arthroplasty using INTERTAN to solve internal fixation failure caused by cut-through of Proximal Femoral Nail Antirotation-II (PFNA-II). Four years after closed reduction and internal fixation of the right femur, the patient had immobilizing right hip pain and mobility disorder. X-ray examination revealed contraction of the neck of the right femur and cut-through of the helical blade of the PFNA-II. After the revision operation, he recovered well and presented no grown pain or discomfort in weight-bearing. Conventional radiographs at 1-year follow-up showed a healed fracture, with no implant migration. CONCLUSION: Main nail exchange and revision with INTERTAN can be considered a salvage procedure in selected cases to revise a failed fixation with PFNA, which solves internal fixation failure as well as preserves the femoral head.

Functional results and unfavorable events after treatment of proximal humerus fractures using a new locking plate system.

BACKGROUND: Proximal humerus fractures are often treated with a fixed-angle titanium plate osteosynthesis. Recently, plates made of alternative materials such as carbon fibre-reinforced polyetheretherketone (CFR-PEEK) have been introduced. This study presents the postoperative results of patients treated with a CFR-PEEK plate. METHODS: Patients with proximal humerus fractures treated with a CFR-PEEK plate (PEEKPower™ Humeral Fracture Plate (HFP)) were included. In follow-up examination, age and gender adjusted Constant-Murley Score (ACS), Subjective Shoulder Value (SSV), Quick Disabilities of the Arm, Shoulder and Hand Score (QDASH) and pain score (Visual Analog Scale (VAS)) were analyzed. General condition at follow-up was measured by European Quality of Life 5 Dimensions 3 Level Version (EQ-5D-3L). Range of motion was recorded. In addition, radiographs at follow-up, unfavorable events and revision rate were analyzed. RESULTS: In total, 98 patients (66.0 ± 13.2 years, 74 females, 24 males) were reexamined. Mean follow-up was 27.6 ± 13.2 months. There were 15 2-part, 28 3-part and 55 4-part fractures. The functional scores showed good results: SSV 83.3 ± 15.6%, QDASH 13.1 ± 17.0 and ACS 80.4 ± 16.0. A 4-part-fracture, head split component, nonanatomic head shaft reposition and preoperative radiological signs of osteoarthritis were significant negative predictors for poorer clinical scores. Unfavourable events were observed in 27 patients (27.6%). Revision surgery was performed in 8 (8.2%) patients. Risk factors for an unfavourable event were female gender, age of 50 years and older, diabetes, affected dominant hand, 4-part fracture, head split and preoperative radiological signs of osteoarthritis. CONCLUSION: There are several advantages of the CFR-PEEK plate (PEEKPower™ Humeral Fracture Plate (HFP)) such as the polyaxial screw placement and higher stability of locking screws. In summary, the CFR-PEEK plate osteosynthesis is a good alternative with comparable clinical results and some biomechanical advantages. Proximal humerus fractures show good clinical results after treatment with a CFR-PEEK plate. The revision rate and the risk of unfavorable events are not increased compared to conventional titanium plate osteosynthesis. LEVEL OF EVIDENCE: IV.

Augmented osteosynthesis in fragility fracture.

Due to poor bone quality and complexity, some fractures are difficult to treat, with high risk of failure. Moreover, general health is often poor in elderly patients with multiple comorbidity and poor compliance, necessitating perfect first-line management to avoid re-operation. The armamentarium comprises specific internal fixation implants and also complementary methods such as autologous, homologous or heterologous bone graft or bone substitutes with varying mechanical and biological characteristics. Associating these options is what is mean by "augmented fixation". The present review of augmented osteosynthesis addresses the following questions: What are the characteristics of fragility fractures? Fragility fracture is caused by low-energy trauma on bone with poor structural quality and low mineral density. Treatment aims to enable early mobilization and weight-bearing while avoiding mechanical failure of fixation. Prolonged bedrest, loss of mobility and surgical revision are aggravating and sometimes fatal factors in these fragile patients. What are the biological techniques of fixation augmentation in fragility fracture? Autologous or homologous bone graft are the most widely used biological augmentation techniques. They fill spaces and promote osteoconduction and consolidation. Some bone-like phosphocalcic structures are opening up promising lines of research. What are the non-biological techniques of fixation augmentation in fragility fracture? Hydroxyapatite, phosphocalcic cement and acrylic cement are the most widely used synthetic materials. Biological and mechanical effects are variable according to composition, requiring specific implementation. What are the mechanical techniques of fixation augmentation in fragility fracture? There is at present no consensus as to the augmentation techniques to be applied in fragility fracture. Cerclage or complementary plating, or external fixation associated to internal fixation are possibilities. However, the literature consists only of small series reporting surgical techniques specific to a given surgeon or team. When and how should osteosynthesis for fragility fracture be augmented? The choice of augmentation depends on fracture location, comminution, available material and local experience. The more severe the fracture, the more complex the fixation. The approach needs to be adapted to the preoperative planning and the associated mechanical means (plate, complementary cerclage) and prosthetic replacement should be considered in certain joint fractures or fractures close to load-bearing surfaces.

Combined Deflection Angle Classification: A Novel Typing System of Adult Femoral Neck Fracture.

OBJECTIVE: Femoral neck fracture (FNF) is a common clinical trauma with high mortality and disability rates. Furthermore, its incidence increases exponentially with increasing age. Existing classifications have some disadvantages. Thus, this study aimed to establish a novel typing system for FNF. METHODS: We retrospectively analyzed all adult patients with FNF admitted to our hospital between December 2015 and November 2017 for cannulated screw internal fixation. The study population was divided into the femoral varus offset group (VAR) and the valgus offset group (VAL). The data collected included sex, age, affected side, injury mode, body mass index, complications, pelvic incidence (PI), hip deflection angle (HDA), combined deflection angle (CDA), and neck shaft angle. Statistical analysis was conducted to determine the correlation between complications and deviation angles. A novel typing system was developed and compared with the Garden classification to detect its superiority. RESULTS: A total of 108 patients were recruited, with 59 patients in the VAR and 49 patients in the VAL groups. The incidence of complications in the VAR group was significantly higher than that in the VAL group (P < 0.05). Moreover, there were more male participants in the VAR group. Compared with the VAL group, the VAR group had significantly higher PI, HDA, and CDA (P < 0.05). The CDA classification (CDAC) was defined, with CDA as the main criterion and HDA as the supplementary criterion. Furthermore, there was a hierarchical correlation between the actual incidence of complications and the typing level, which was increased in CDAC but not in the Garden classification. This showed that CDAC was more accurate. CONCLUSION: A novel typing system, CDAC, for FNF was established, which was more accurate than the Garden classification. We suggest combining CDAC and Garden classifications for the preoperative diagnosis, treatment selection, and prognostic evaluation for patients with FNF.

Emergency versus semi-elective management of mandible fractures: a Maxillofacial Trainee Research Collaborative (MTReC) study.

INTRODUCTION: Recent evidence suggests that acute emergency management of mandible fractures does not improve surgical outcomes yet is associated with increased financial burden. Current NHS policy advocating for increased adoption of day-case and semi-elective surgical procedures to reduce bed strain must be balanced with providing timely, effective treatment. Our research aims to determine patient groups currently managed via semi-elective admission and whether this can be extended to other groups to provide safe and effective management of mandible fractures. METHODS: A multi-national trainee-led audit of mandibular fractures across 49 units was completed by the Maxillofacial Trainee Research Collaborative (MTReC). Each unit prospectively collected data on fractures on admission and at follow-up. Data collected included patient demographics, behaviour, health, injury, timing to intervention and surgical complications. RESULTS: Data were collected on 947 mandibular fractures. Of the surgically managed patients, 649 (90%) were managed via acute emergency admission at the time of presentation, while 68 (10%) were managed semi-electively. Patient demographics, injury pattern and mechanism appeared to significantly affect timing of management, whereas patient behaviour, health status, timing of injury and presentation did not. Semi-elective management was associated with a significantly shorter inpatient duration (0.9 versus 1.9 days, p=0.000) with no differences in readmission, antibiotic usage or surgical complications (p=1.000, RR 1.030). CONCLUSION: Our study demonstrates the efficacy of planned admissions and semi-elective management of mandibular fractures. Simple mandibular fractures in compliant patients are suitable for semi-elective treatment. Holistic patient assessment and tailored surgical planning is crucial in determining admission modality to effectively manage mandibular trauma.
