The Evaluation of Objective and Subjective Fate of Teeth in the Mandible Fracture Line and the Management-A Center's Experience.

OBJECTIVE: The decision to retain or extract teeth in the line of mandibular fractures has been a subject of debate in much of the scientific literature, and there is a need for further evidence to clear this issue. Thus, the aim of this study was to investigate both the positive and negative effects of teeth in the line of mandibular fractures provide more evidence in this field, as well as take into consideration patients' quality of life after the surgery. METHODS: Patients after trauma with teeth in the line of mandibular fractures were included in this study. Open reduction and rigid internal fixation, elastic intermaxillary reduction were expected to achieve a satisfactory occlusion and/or anatomical reduction in the fragments as assessed by orthopantomogram, computed tomography scans, and clinical examination. The remaining cases had maxillomandibular fixation (MMF) with an arch bar and bridle wire. All the patients included in this study will take the Visual Analog Scale score evaluation before and after surgery subjectively to further verify the impact on their life qualify, as well as the further treatment needed. RESULTS: A total of 78 patients with teeth in the line of mandibular fractures were included in this study. Open reduction and rigid internal fixation was used in 37 patients, whereas another 35 patients accepted elastic intermaxillary reduction. Six cases underwent MMF. The number of involved teeth was 83. Three of the 83 teeth involved in the fracture lines healed with complications. In the cases where the teeth had been removed before fracture treatment, or in cases of delayed extractions, no complications were noted. The majority of the patients felt good about the whole treatment, however, 4 in the MMF group complained about worry about their oral health due to MMF leading to mouth open limitation. CONCLUSION: The factors that should be considered for removal include the condition of the teeth and alveolar bone, the timing and the type of treatment, as well as the patients' desire, if possible. This is an individual-based decision that needs to consider more objective and subjective potential risks to avoid complications.

Should We Fix the Fibula in Tibial Plafond Fractures? A Meta-analysis Reviewing the Evidence Base for Fibula Open Reduction and Internal Fixation in Tibial Plafond Fractures.

Open reduction and internal fixation are the standard of care to stabilize tibial plafond fractures. However, it remains uncertain as to whether fixation of the fibula affects the outcome. This study aimed to review the evidence base for comparable outcomes in tibial plafond fractures when undergoing open reduction and internal fixation of ipsilateral fibula fractures compared with open reduction and internal fixation of the tibia alone. A systematic review and meta-analysis of the literature was completed; 4 studies were included for analysis. This study demonstrated no statistically significant differences in the incidence of nonunion (p = .784) or mal-union (p = .416). There was a greater rate of removal of metalwork in the fibula operative group compared to the tibia alone group (p < .001). The current evidence demonstrates that open reduction and internal fixation of ipsilateral fibula fractures in tibial plafond fractures is not necessarily routinely indicated for all fractures.

Impact of surgical timing and type of operative procedure on outcomes in periprosthetic hip fractures: an observational study at an NHS trust centre in the UK.

PURPOSE: There is a global trend of increased periprosthetic fractures due to the growing number of arthroplasty procedures. The present study assessed the impact of factors such as time to surgery and type of surgery on the outcomes, which have been seldom evaluated for periprosthetic fractures. METHODS: An observational study was conducted on consecutive 87 patients within an NHS district hospital trust in the UK. Patients who underwent a complete hip replacement prior to the fracture, received fixation therapy, or underwent revision surgery within the specified time were screened. Patients were grouped in two ways: based on time to surgery and based on surgery type. Logistic regression models were performed to assess for statistically significant differences in post-operative complication, 30-day, and 1-year mortality rates between groups, whilst adjusting for age, gender, and ASA grade. RESULTS: Forty-one patients underwent open reduction and internal fixation (ORIF), 29 patients underwent revision arthroplasty, and 17 patients were subjected to both, ORIF and revision arthroplasty. Sixty of the 87 patients were operated on > 48 h of injury. The median hospital stay was significantly lower in the ORIF plus revision arthroplasty group, versus other surgical groups (p < 0.05) whilst it was significantly higher in the group of patients who underwent surgery after 48 h of injury (p < 0.05). Numerically higher mortality was noted in the revision arthroplasty group (31.03%, p > 0.05). The group that was operated after 48 h of injury showed greater mortality but was comparable to the other group (25% vs. 14.81%, p > 0.05). For post-operative complications, none of the variables were significantly predictive (p > 0.05). However, for 30-day mortality, ASA grade (p = 0.04) and intra-operative complications (p = 0.0001) were significantly predictive. Additionally, for 1-year mortality, ASA grade (p = 0.004) was noted to be significantly predictive. CONCLUSION: Revision and delayed periprosthetic fracture management (> 48 h after injury) group showed a numerically greater mortality risk; however, this finding was not statistically significant. ASA grading at baseline is predictive of mortality for periprosthetic fractures.

Catastrophic failure of a titanium locking plate in a proximal humeral fracture: case report and literature review.

BACKGROUND: Angular stable locking plates have shown good clinical results in treating proximal humeral fractures, but complications are not uncommon. This study reported a rare case of catastrophic failure of a titanium locking plate. A retrieval analysis of the implants was performed using an optic microscope and a scanning electron microscope. CASE PRESENTATION: A 69-year-old male reported a right proximal humeral fracture at the surgical neck and was treated by open reduction and internal fixation with a locking plate system. Ninety-six days after surgery, the patient came to clinic for acute local pain over the shoulder without any trauma. The radiographs showed a complete breakage of the implant accompanying displaced fracture. Revision surgery was performed to restabilize the fracture with a longer locking plate. The follow-up radiographs at 9 months showed complete union of the bone fracture. CONCLUSIONS: From the retrieval analysis, repetitive torsion loads on the vulnerable area of the implant are assumed to cause this catastrophic event. It is recommended that adequate activity restriction, such as reaching, be undertaken to avoid this rare complication. Current study also provides contributive information for the modification of plate design and pre-operative planning for device configuration to improve the success rate of locking plate fixation.

Humeral shaft fractures: a cost-effectiveness analysis of operative versus nonoperative management.

BACKGROUND: Humeral shaft fractures can be managed operatively or nonoperatively with functional bracing in the absence of neurovascular injury, open fracture, or polytrauma. A consensus on optimal management has not been reached, nor has the cost-effectiveness perspective been investigated. METHODS: A decision tree was constructed describing the management of humeral shaft fractures with open reduction-internal fixation (ORIF), intramedullary nailing (IMN), and functional bracing in a non-elderly population. Probabilities were defined using weighted averages determined from systematic review of the literature. Cost-effectiveness was evaluated with incremental cost-effectiveness ratios, measured in cost per quality-adjusted life-year (QALY). Willingness-to-pay thresholds of $50,000/QALY and $100,000/QALY were evaluated. RESULTS: Eighty-six studies were included. Using bracing as the referent in the health care model, we observed that bracing was the preferred strategy at both incremental cost-effectiveness ratio thresholds. ORIF and IMN had higher overall effectiveness (0.917 QALYs and 0.913 QALYs, respectively) compared with bracing (0.877 QALYs). The cost-effectiveness of bracing was driven by a substantially lower overall cost. In the societal model-accounting for both health care and societal costs-the cost difference narrowed between bracing, ORIF, and IMN. Bracing remained the preferred strategy at the $50,000/QALY threshold; ORIF was preferred at the $100,000/QALY threshold. ORIF and IMN were comparable strategies across a range of probability values in sensitivity analyses. CONCLUSIONS: Functional bracing, with its low cost and satisfactory clinical outcomes, is often the most cost-effective strategy for humeral shaft fracture management. ORIF becomes preferable at the higher willingness-to-pay threshold when societal burden is considered. QALY values for ORIF and IMN were comparable.

Understanding postoperative rehabilitation preferences in operatively managed proximal humerus fractures: do trauma and shoulder surgeons differ?

BACKGROUND: Proximal humerus fractures (PHFs) are common, and their incidence is increasing as the population ages. Despite this, postoperative rehabilitation remains unstandardized and little is known about surgeon preferences. The aim of this study was to assess differences in postoperative rehabilitation preferences and patient education between orthopedic trauma and shoulder surgeons. METHODS: An electronic survey was distributed to members of the Orthopaedic Trauma Association and the American Shoulder and Elbow Surgeons to assess differences in postoperative rehabilitation preferences and patient counseling. Descriptive statistics were reported for all respondents, trauma surgeons, and shoulder surgeons. Chi-square and unpaired 2-sample t tests were used to compare responses. Multinomial regression was used to further elucidate the influence of fellowship training independent of confounding characteristics. RESULTS: A total of 293 surgeons completed the survey, including 172 shoulder and 78 trauma surgeons. A greater proportion of trauma surgeons preferred an immediate weightbearing status after arthroplasty compared to shoulder surgeons (45% vs. 19%, P = .003), but not after open reduction and internal fixation (ORIF) (62% vs. 75%, P = .412). A greater proportion of shoulder surgeons preferred home exercise therapy taught by the physician or using a handout following reverse shoulder arthroplasty (RSA) (21% vs. 2%, P = .009). A greater proportion of trauma surgeons began passive range of motion (ROM) <2 weeks after 2-part fractures (70% vs. 41%, P < .001). Conversely, a greater proportion of shoulder surgeons began passive ROM between 2 and 6 weeks for 2-part (57% vs. 24%, P < .001) and 4-part fractures (65% vs. 43%, P = .020). On multinomial regression analysis, fellowship training in shoulder surgery was associated with preference for a nonweightbearing duration of >12 weeks vs. 6-12 weeks after ORIF. Similarly, fellowship training in shoulder surgery was associated with increased odds of preferring a nonweightbearing duration of <6 weeks vs. no restrictions and >12 weeks vs. 6-12 weeks after arthroplasty. Training in shoulder surgery was associated with greater odds of preferring a nonweightbearing duration prior to beginning passive ROM of 2-6 weeks vs. <2 weeks or >6 weeks for 2-part fractures, but not 4-part fractures. CONCLUSION: Trauma surgeons have a more aggressive approach to rehabilitation following operative PHF repair compared to shoulder surgeons regarding time to weightbearing status and passive ROM. Given the increasing incidence of PHFs and substantial variations in reported treatment outcomes, differences in rehabilitation after PHF treatment should be further evaluated to determine the role it may play in the outcomes of treatment studies.

New Minimally Invasive Intraoral Procedure for Condylar Fractures: Clinical Presentation and Considerations on Current Techniques.

ABSTRACT: Mandibular fractures are the third most prevalent maxillofacial traumatic events. Surgical approaches to the condyle are a debated topic. This study describes a mini-invasive technique for condylar fracture reduction. The patient of this study suffered multiple traumatic injuries including a carotid artery dissecting aneurysm, which contraindicated the standard open reduction and internal fixation technique. The novel minimally invasive technique involves intraoral access and fracture fragment realignment using a periosteal elevator, a molar occlusal splint, and intermaxillary fixation after intraoperative radiologic imaging confirmation of condyle reposition.The approach avoids skin incisions and tissue dissection, with good aesthetic outcomes and facial nerve preservation. This technique proved to be safe and simple to be less demanding for the patient, with a shorter recovery time than experienced with other techniques.The results suggest this technique is a good option for the surgical treatment of condylar neck fractures showing favorable rim morphology with primary stability after reduction.

Acetabulum fractures in elderly patients: A review.

Fractures of the acetabulum in elderly patients were often caused by low energy trauma. Fractures involving anterior column are more common and often associated with impaction and comminution. Osteoporosis further complicates the management. Percutaneous fracture fixation has low morbidity but it is a technically demanding procedure. Open reduction and fracture fixation is done with or without simultaneous total hip replacement. Delayed total hip replacement is considered in posttraumatic arthritis patients. Patients with minimal displaced fractures, associated both-column fractures with secondary congruence of joint and patients who are medically unfit for surgery can be managed non-operatively. Whatever be the method of management, these elderly patients should be mobilised as early as possible.

Tourniquet Use During Open Reduction and Internal Fixation of Ankle Fractures - A Systematic Review and Meta-Analysis.

The intra-operative use of tourniquet in open reduction and internal fixation (ORIF) of ankle fractures remains a topic of debate. The purpose of this study was to perform a systematic review and meta-analysis of randomized control trials (RCTs) comparing clinical outcomes of patients undergoing ankle ORIF with tourniquet use versus a control group where no tourniquet was used. A systematic review was performed with reference to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines of the Pubmed, Scopus, Embase, and Cochrane Library databases. Studies were included if they were an RCT comparing tourniquet and no-tourniquet in ankle ORIF. Meta-analysis was performed using RevMan, and p-value <.05 was considered to be statistically significant. On completion of the literature search, a total of 4 RCTs including 350 ankles (52.6% males), with a mean age of 47.1 ± 5.7 years were included. There were 173 patients in the tourniquet group (T), versus 177 patients in the no tourniquet control group (NT), with nonsignificant differences between the groups for age, gender and body mass index demographics (all p > .05). There were significantly shorter duration of surgery, with significantly higher patient-reported rates of pain levels at day 2 postoperatively (both p < .001) in the T group. Additionally, there were significantly greater ranges of ankle motion at 6 weeks postoperatively (p = .03), with nonsignificant differences reported incidence of wound infections and deep vein thrombosis (p = .056 and p = .130 respectively) between the groups. In conclusion, current evidence suggests that although intraoperative tourniquet usage in cases of ankle ORIF results in significant reductions in duration of surgery, this may be at the expense of higher patient-reported pain scores and reduced range of motion postoperatively.

Percutaneous Prodding Reduction and K-Wire Fixation Via Sinus Tarsi Approach Versus ORIF for Sanders Type III Calcaneal Fractures: A Prospective Case-Controlled Trial.

We conducted a prospective randomized controlled trial to compare the radiological and clinical outcomes of Sanders type III calcaneal fractures treated with percutaneous prodding reduction and K-wire fixation via a sinus tarsi approach (PPRKF) versus open reduction and internal fixation (ORIF). Fifty-one patients with closed, unilateral, Sanders type III calcaneal fractures were randomly assigned to the PPRKF group (n = 26) or the ORIF group (n = 25). The clinical outcomes evaluated were time to surgery, blood loss, operative time, hospital stay, wound healing time, wound complications, and Maryland foot score. Radiological results were evaluated on lateral and axial X-rays and computed tomography images and included Böhler's angle, Gissane's angle, and calcaneal width. Compared with the ORIF group, the PPRKF group had shorter time to surgery, shorter operative time, less blood loss, shorter hospital stay, shorter wound healing time, and fewer wound complications (p < .001). The postoperative Böhler's angle, Gissane's angle, and calcaneal width in both groups were significantly better than those measured preoperatively (p < .001) and did not differ between the PPRKF group and ORIF group (p> .05). Regarding clinical results, there was no significant difference in Maryland foot score between the two groups at 12 months after surgery (p > .05). Both PPRKF and ORIF can result in satisfactory clinical function. PPRKF is superior to ORIF in reducing the time to surgery, operative time, blood loss, hospital stay, wound healing time, and wound complications.

External validity in a multicenter randomized clinical trial of proximal humeral fractures: the DelPhi trial.

BACKGROUND: Randomized controlled trials (RCT) are regarded as the gold standard for effect evaluation in clinical interventions. However, RCTs may not produce relevant results to all patient groups. We aimed to assess the external validity of a multicenter RCT (DelPhi trial). METHODS: The DelPhi RCT investigated whether elderly patients with displaced proximal humeral fractures (PHFs) receiving reversed total shoulder prosthetic replacement (RTSA) gained better functional outcomes compared to open reduction and internal fixation (ORIF) using an proximal humerus locking plate (PHILOS). Eligible patients were between 65 and 85 years old with severely displaced 11-B2 or 11-C2 fractures (AO/OTA-classification, 2007). We compared baseline and follow-up data of patients for two of the seven hospitals that were included in the DelPhi trial (n = 54) with non-included patients (n = 69). Comparisons were made based on reviewing medical records regarding demographic, health and fracture parameters. RESULTS: Forty-four percent of the eligible patients were included in the DelPhi trial. Comparing included and non-included patients indicated higher incidences of serious heart disease (P = 0.044) and a tendency toward higher tobacco intake (P = 0.067) in non-included patients. Furthermore, non-included patients were older (P = 0.040) and had higher ASA classification (P < 0.001) and were in more need for resident aid (in-home assistance) (P = 0.022) than included patients. The cause of PHF was more frequently related to fall indoors in non-included vs. included patients (P = 0.018) and non-included patients were more prone to other concomitant fractures (P = 0.004). Having concomitant fractures was associated with osteoporosis (P = 0.014). We observed no significant differences in rates of complications or deaths between included and non-included patients within 3 months after treatment. In descending order, non-included patients were treated conservatively, with PHILOS, RTSA, anatomic hemi-prothesis or an alternative type of ORIF. RTSA was the preferred treatment choice for C2-type fractures (P < 0.001). CONCLUSIONS: Results from the DelPhi RCT may not directly apply to older PHFs patients with lower health status or concomitant fractures. LEVEL OF EVIDENCE: Level 4.

Local Random Pattern Flap Coverage for Implant Exposure following Open Reduction Internal Fixation via Extensile Lateral Approach to the Calcaneus.

BACKGROUND: Skin necrosis and implant exposure most often appear at the corner of Extensile Lateral Approach for open reduction and internal fixation (ORIF) for displaced intra-articular fracture of the calcaneus. Flap transfer is often used for coverage of this implant exposure. We introduced a new simple local random pattern flap to cover the implant exposure. METHODS: From March 2017 to March 2020, 12 patients with implant exposure after ORIF for displaced intra-articular fracture of the calcaneus were treated with this procedure. The sizes of the defects ranged from 2 × 2 cm2 to 5 × 2 cm2. A local random pattern flap was designed according to the defect size. The lower edge of the flap was along with the wound upper edge and extended distally. The upper horizontal incision of the flap was made at the lateral malleolus level with a length of 5-7 cm depending on the wound defect. Then the random pattern flap was elevated and transferred to cover the defect area. RESULTS: The mean follow-up duration was 6.3 months (ranging 4-13 months). All 12 flaps were uneventfully healed and all patients were able to wear shoes, and no debulking procedures were required. CONCLUSION: The local random pattern flap could be a choice for surgeons when implant exposure at the corner of Extensile Lateral Approach to the Calcaneus occurs.

Intraoperative Nice knots assistance for reduction in displaced comminuted clavicle fractures.

PURPOSE: The Nice knots have been widely used in orthopedic surgeries to fix torn soft tissue and fracture in recent years. The study aims to investigate the clinical efficacy and prognosis of intraoperative and postoperative Nice Knots-assisted reduction in the treatment of displaced comminuted clavicle fracture. METHODS: From Jan 2014 to Dec 2019, 75 patients diagnosed with unilateral closed displaced comminuted clavicle fracture were treated with open reduction and internal fixation (ORIF) in this study. Nice knot group (the NK group) included 38 patients and the other 37 patients were in the traditional group (the TK group). The time of operation and the amount of bleeding during operation were recorded. Post-operative clinical outcomes and radiographic results were recorded and compared between these two groups. The Visual Analogue Scale (VAS), Neer score, Rating Scale of the American Shoulder and Elbow Surgeons, Constant-Murley score and complications such as infection, nonunion, implant loosening, fragment displacement and hardware pain were observed in the two groups. RESULTS: In the comparison between the two groups, there was no significant difference in age, sex, the cause of displaced clavicle fracture, and other basic information between the two groups. The operation time, intraoperative fluoroscopy time, and intraoperative blood loss were significantly reduced in the NK group (P < 0.01). There were 2 cases of plate fracture in the TK group. The follow-up results showed that there was no significant difference in VAS, Neer score, ASES, and Constant-Murley scores between the two groups. CONCLUSION: The use of Nice knot, in comminuted and displaced clavicle fractures can reduce intraoperative blood loss, shorten operation time, facilitate intraoperative reduction, and achieve satisfactory postoperative clinical results. This study demonstrates that Nice knot is a simple, safe, practical and effective auxiliary reduction method.

Restoration of Ramus Height in Child Patients With Extracapsular Condylar Fractures: Is This Mission Almost Impossible to Accomplish?

OBJECTIVE: This study aimed to assess whether ramus height is restored in children with extracapsular condylar fractures treated by conservative or surgery procedures. METHODS: The sample consisted of 35 children (collected consecutively) less than 12 years old who presented with extracapsular condylar fractures and treated within an 8-year period (June 2011 to April 2019). Data on the age, gender, date of injury, mechanism of trauma, location and pattern of mandibular condylar fracture, associated injuries and treatment methods were recorded and analyzed. Ramus height restoration is the main evaluation indicator during the follow-up period. RESULTS: Within the 8-year record retrieval, the 35 children sustained 41 extracapsular condylar fractures. For the sample size, 10 (24.4%) and 31 (75.6%) had condylar neck and base fractures, respectively. Deviation and green-stick fracture were the predominant types in condylar neck and base fractures, accounting for more than 3 quarters (31, 75.6%). The majority (33, 80.5%) of patients were treated with nonsurgical treatment, and 8 (19.5%) were treated by open reduction and internal fixation (ORIF). During the follow-up period (1-1419 days, average time of 110.6 days), only 1 patient (with bilateral extracapsular condylar fractures) had their ramus height restored (follow-up period, 256 days). Most members of the ORIF group (5 of 8, 62.5%) postoperatively showed bended ramus (deviated angularly/fragment angulation). CONCLUSION: Conservative treatment could hardly restore the ramus height of children with extracapsular condylar fractures. Anatomically or totally restoring the ramus height is difficult even with the surgical treatment of ORIF; however, surgical treatment of ORIF can substantially restore the ramus height for dislocated fractures or seriously displaced fractures.

Open reduction and internal fixation might be a valuable alternative to stem revision in Vancouver B2 periprosthetic femoral fractures, irrespective of the stem's design.

BACKGROUND: The purpose of this study was to compare the clinical and radiological outcomes following open reduction and internal fixation (ORIF) of Vancouver B2 periprosthetic femoral fractures versus stem revision (SR) surgery. METHODS: Between 2004 and 2018, 39 patients were treated with SR and 31 with ORIF for a Vancouver type B2. Mean follow-up was 40.4 months for the ORIF group and 43.5 months for the SR group. 22 of 31 stems in the ORIF group were uncemented, of which 7 (23%) were short stems. Perioperative complications, intraoperative blood loss, revision rate, and mortality were recorded. Functional outcomes included Harris Hip Score, Parker Mobility Score and hip abductor strength. RESULTS: Both groups did not differ in the American Society of Anesthesiologists (ASA) score, Charlson comorbidity index, body mass index, age, and sex. Compared to SR, patients treated with ORIF had a decreased blood loss, transfusion rate, operation duration, and mortality. Total complication and re-operation rates were similar. The relative risk for complication and re-operation was 0.5 and 0.7, respectively, in favour of ORIF. CONCLUSIONS: ORIF might be a valuable alternative to SR in the treatment of Vancouver type B2 periprosthetic fractures with shorter operation duration, lower blood loss and similar complication rate compared to SR. Moreover, re-stabilization seems possible irrespective of stem's design or fixation technique. LEVEL OF EVIDENCE: Level III.

Treatment of irreducible femoral intertrochanteric fractures using a wire-guided device.

PURPOSE: Treatment of irreducible femoral intertrochanteric fractures often requires open reduction. However, the technique unavoidably causes patients to suffer greater trauma. As such, minimally invasive techniques should be employed to reduce the surgical-related trauma on these patients and maintain a stable reduction of the fractures. Herein, a minimally invasive wire introducer was designed and used for the treatment of femoral intertrochanteric fractures. The effectiveness of using a wire-guided device to treat irreducible femoral intertrochanteric fractures was evaluated. METHODS: Between 2013 and 2018, patients with femoral intertrochanteric fractures who were initially treated by intramedullary nail fixation but had difficult reduction using the traction beds were retrospectively reviewed. Decision for an additional surgery was based on the displacement of the fracture. The patients were then divided into two groups: those in the control group received an open reduction surgery while those in the observation group received a closed reduction surgery using a minimally invasive wire introducer to guide the wire that could assist in fracture reduction. The operation time, blood loss, visual analogue scale scores, angulation, reduction, neck-shaft angle, re-displacement, limb length discrepancy, and union time were then recorded and analyzed to determine the efficiency of the wire introducer technique. Categorical variables were analyzed by using Chi-square test, while continuous variables by independent t-test and the Mann-Whitney test accordingly. RESULTS: There were 92 patients included in this study: 61 in the control group and 31 in the observation group. There were no significant differences in baseline demographic factors between the two groups. All surgeries were successful with no deaths within the perioperative period. The average follow-up time for the patients was 23.8 months. However, the observation group had a significantly shorter operation time, lower visual analogue scale score, less intraoperative bleeding, and shorter fracture healing time. There were no significant differences in the angulation, reduction, neck-shaft angle, and limb length discrepancy between the two groups. CONCLUSION: The minimally invasive wire guide achieved a similar effect to that of open reduction in the treatment of intertrochanteric fractures with difficult reduction. Moreover, the minimally invasive wire introducer is a good technology that accurately guides the wire during reduction. Indeed, it is an effective technique and achieves good clinical outcomes in restoration of irreducible femoral intertrochanteric fractures.

Posterior shoulder fracture-dislocation: A systematic review of the literature and current aspects of management.

PURPOSE: Posterior fracture-dislocation of shoulder is an infrequent traumatic event; however, most orthopaedic surgeons may face the challenge of treating it. The aim of this study is to review and summarise systematically the current principles of the management of this complex injury, and create a treatment algorithm. METHODS: Both PubMed and Scopus Databases were systematically searched for the terms "posterior shoulder fracture-dislocation" or "posterior glenohumeral fracture-dislocation" or "posterior glenoid fracture-dislocation" for articles written in English and published in the last decade. RESULTS: A total of 900 articles were identified, of which 13 were retained for analysis. A total of 153 patients (161 shoulders) were identified. These patients were treated either with open reduction and internal fixation, modified McLaughlin procedure, allograft/autograft humeral head reconstruction or shoulder arthroplasty. The mean age was 40.15 years. The mean postoperative Constant score in cases treated by open reduction and internal fixation was 86.45, whereas by bone graft was 84.18. Further, the mean postoperative Constant score was between 79.6 and 67.1 in those that were managed by modified McLaughlin and arthroplasty procedure, respectively. CONCLUSION: The management of posterior shoulder fracture-dislocation may be challenging, and the best surgical option depends on many variables such as the chronicity of the injury, the presence of a fracture at the level of the surgical neck or tuberosities and the extend of the Hill-Sachs lesion if any. A treatment algorithm is proposed, based on the current literature in an effort to create a consensus for these injuries. For the acute shoulder fracture-dislocations, an open reduction should be performed. For the chronic fracture/dislocations in the elderly low-demand patients, conservative treatment should be performed. For the rest of the patients, depending on the severity of the Hill-Sachs lesion different surgical options are available such as the McLaughlin technique, the use of an allograft, osteotomy or arthroplasty.

Minimally invasive treatment of AO B ankle fractures: Surgical technique and long-term outcomes.

BACKGROUND: Ankle fractures are the most common traumatic bone injuries of the lower limb. Over 50% of ankle fractures occur at the syndesmosis level (type AO B). The goal of treatment is to achieve an anatomical reduction and appropriate stabilization. The present study aimed to evaluate the clinical-functional and radiological results, and complications of minimally invasive reduction and fixation technique for ankle fractures type AO B. The surgical technique also is detailed. MATERIAL AND METHODS: A prospective analysis of 451 patients undergoing surgery for type AO B displaced ankle fracture was performed. All patients were treated with minimally invasive surgery. The following times were recorded: time between trauma and osteosynthesis, hospitalization length, surgical time, and exposure time to fluoroscopy. Age and gender, mechanism of injury, and characteristics of fractures were recorded. For functional outcome, AOFAS score, VAS, and Weber score were used. Radiographic analysis was performed. The average follow-up was 112 months. RESULTS: Mean age was 48.2 years old. Average length of stay in hospital was 5.72 h. Mean duration of the surgery was 32.8 min. Average fluoroscopic exposure time during surgery was 9.25 s. Mean bone union time was 38.2 days. Weber's score was on average 1.5/24 points and the long-term follow-up AOFAS score was on average 97.5/100. Postoperative complications incidence was 2.7%. CONCLUSIONS: Distal fibula fixation with the MIPO technique presented good functional outcomes and could be helpful in the avoidance of the complications associated with conventional open reduction and internal fixation. However, it needs more exposition to intraoperative fluoroscopy. LEVEL OF EVIDENCE: II.

Will Closed Treatment Provide Better Mandibular Motion Than Open Reduction and Internal Fixation in Cases of Unilateral Displaced Subcondylar Fracture? A Systematic Review and Meta-Analysis.

PURPOSE: The aim of the present systematic review was to determine whether closed treatment (CLT) with intermaxillary fixation (IMF) is superior or equivalent to open reduction and internal fixation (ORIF) in the management of unilateral displaced subcondylar fractures regarding the range of mandibular motion. MATERIALS AND METHODS: To address our question, we conducted a systematic review and meta-analysis of the reported data after a comprehensive manual and electronic database search of studies reported up to 2017 in the English language that had compared CLT and ORIF of mandibular condyle fractures in adults. The following outcomes were recorded: maximum interincisal opening (MIO), protrusive movement (PM), lateral excursion toward the fractured side (LEFS), and lateral excursion toward the nonfractured side (LENFS). RESULTS: The search resulted in 8 studies, 4 of which were included in the meta-analysis. The MIO and PM showed no statistically significant differences, with an effect size of -0.823 (P = .112) and -0.633 (P = .079), respectively. However, the LEFS and LENFS were superior after CLT, with an effect size of -0.710 (P = .031) and -0.682 (P = .017), respectively. CONCLUSIONS: The findings from the present review suggest that both ORIF and CLT can provide comparable MIO and PM in subjects with unilateral displaced subcondylar fractures. However, CLT was superior to ORIF for both LEFS and LENFS.

Cost-Minimization Analysis and Treatment Trends of Surgical and Nonsurgical Treatment of Proximal Humerus Fractures.

PURPOSE: Recent evidence demonstrated similar outcomes between nonsurgical and surgical management of displaced proximal humerus fractures. We analyzed treatment trends and performed a cost-minimization analysis comparing nonsurgical treatment, open reduction and internal fixation, reverse total shoulder arthroplasty, and hemiarthroplasty. We hypothesized that rates of surgical treatment have increased and that the costs associated with surgery are greater compared with nonsurgical management of proximal humerus fractures. METHODS: We used a US private-payer claims database of 22 million patient records from 2007 to 2016 to compare (1) cost for the episode of care from the payer perspective between each surgical group and nonsurgical treatment of proximal humerus fractures, and (2) annual trends and complication rates of each group. Cost data, including facility fees, physician fees, physical therapy, and clinic visits, were used to complete a cost-minimization analysis. RESULTS: Nonsurgical treatment was associated with lower average total costs compared with surgical intervention. Facility and physician fees accounted for most of this difference. Physical therapy costs and number of physical therapy visits were higher in each surgical group compared with nonsurgical treatment. Surgical treatment was associated with higher complications, revision rates, and length of stay. There was a small but statistically significant decrease in nonsurgical management of proximal humerus fractures between 2007 and 2016. No change was observed in rates of open reduction and internal fixation, whereas rates of reverse total shoulder arthroplasty increased and rates of hemiarthroplasty decreased. CONCLUSIONS: Nonsurgical management of proximal humerus fractures decreased during the study period. In the setting of treatment equipoise, cost-minimization analysis favors nonsurgical management of proximal humerus fractures. Surgical management is associated with higher complication rates, revision rates, and length of stay. TYPE OF STUDY/LEVEL OF EVIDENCE: Economic Decision Analysis IV.
