RESUMEN
Fracture healing has four phases: haematoma formation, soft callus, hard callus and remodelling. Often, non-healing fractures have an arrest of one of these phases, which need resurgery. We have repurposed denosumab for impaired fracture healing cases to avoid surgical intervention. Here, we report a series of three cases of impaired fracture healing where denosumab was given 120 mg subcutaneous dosages for 3 months to enhance healing. All the three cases have shown complete bone union at a mean follow-up of 6.7 months (5-9 months) as assessed clinically and radiologically, and have observed no adverse effect of the therapy. Denosumab given in this dose aids fracture healing by increasing callus volume, density and bridges the fracture gap in recalcitrant fracture healing cases where the callus fails to consolidate.

BACKGROUND: The purpose of this study is to examine pediatric patients with a radial neck fracture and determine the factors associated with a failed closed reduction (CR) in the emergency department (ED). METHODS: A total of 70 patients with acute radial neck fractures were retrospectively reviewed. Inclusion criteria were: age 18 years or younger at time of injury, diagnosis of radial neck fracture without other associated elbow fractures, an attempt at CR with manipulation in the ED or immediate surgery, open proximal radial physis, and appropriate imaging to categorize the injury. Charts were reviewed and demographic data was obtained. Initial injury films were reviewed and the Judet classification was used to define fracture types/categories. RESULTS: CR was attempted on 41 patients. Twenty-nine patients went straight to surgery without a CR attempt. Compared with patients that had an attempted CR in the ED, patients that went straight to surgery had longer mean time from injury to ED presentation (5.6 d; P=0.0001), greater mean fracture angulation (55.0 degrees; P=0.001), and greater fracture translation (46.2%; P=0.001). When analyzing the patients that had a CR attempted in the ED, univariate statistical analysis demonstrated that ≥Judet 4 classification (P=0.03), greater amounts of fracture angulation (P=0.003), and a treatment delayed >24 hours from injury (P=0.007) were significant risk factors for failure of CR in the ED. Zero (0/10) patients with fracture angulation ≥60 degrees had a successful CR. Only 1/14 patients presenting >24 hours after injury had a successful CR in the ED. CONCLUSIONS: Circumventing sedation in the ED, and instead splinting for a planned surgical intervention may be a more efficient treatment method for pediatric radial neck fractures that present to the ED>24 hours after injury and/or have angulations ≥60 degrees. Adopting this new strategy may save time, reduce costs, and avoid possible harm/complications associated with sedation in the ED. LEVEL OF EVIDENCE: Level III-prognostic.

OBJECTIVE: Sympathetic blocks are used as an adjunct for pain management in the treatment of orthopedic and traumatic conditions. Stellate ganglion (ganglion stellatum) provides sympathetic innervation of the head, neck and cervicothoracic regions, and upper extremities. No study was found in the literature investigating the effects of stellate ganglion block performed in the upper extremity, on blood supply to bone, density, vascularization, and bone metabolism. Therefore, the objective of this study was to investigate the effects of stellate ganglion block on healing of closed forearm fractures that were induced in rats. Material and Methods. A total of 42 Wistar albino rats weighing between 398 and 510 g were used in this study. The rats were randomly divided into 2 groups with one group treated with stellate ganglion and the other included as the control group. In each 2 groups, a closed forearm fracture was created, confirmed with X-ray, and then stabilized by splint application. The forearm bones were examined with X-ray views on the same day and were then decalcified. RESULTS: When histological findings of the fracture region were examined, predominantly cartilage and less woven bone were found in 7 rats, equally distributed cartilage and immature bone in 14 rats, and predominantly imitation bone and less cartilage formation in 21 rats. In the control group, the agreement between the 1st and 2nd orthopedists for the radiological evaluation of bone formation was moderate. CONCLUSION: The group administered stellate ganglion block showed a more significant fracture healing.

PURPOSE: Repeat intervention for pediatric forearm fractures after closed manipulation is as high as 46% with flexed elbow (FE) long-arm casts. Casting with the elbow extended (EE) has been advocated as an alternative technique. We documented outcomes of patients treated with closed manipulation and casting with EE long-arm casts for displaced, diaphyseal both-bone forearm fractures. METHODS: We retrospectively reviewed charts for patients who had sedated manipulations and casting for closed, diaphyseal forearm fractures. Open fractures, immediate surgical intervention, metabolic bone disease, recurrent fractures, and Monteggia injuries were excluded. Closed manipulations were performed by orthopaedic residents assisted by cast technicians, with sedation provided by emergency department physicians. Radiographic angulation and displacement of the radius and ulna on immediate postreduction radiographs and all follow-up radiographs were recorded. Patients requiring repeat intervention were compared with those who did not by using the Mann-Whitney U and Fisher exact tests. RESULTS: Of 86 patients (7.2±2.8 y) available for analysis, 82 (95.3%) completed treatment after a single-sedated manipulation and placement of an EE long-arm cast. There were no malunions or nonunions. The average follow-up was 50 days. Four (4.7%) patients required repeat interventions (2 had surgery, 1 had a repeat sedated manipulation, and 1 had a nonsedated manipulation). There were no statistically significant differences in age, sex, laterality, fracture position in the diaphysis, or immediate postreduction angulation of the radius or ulna. A literature review showed average repeat intervention rates of 14.9% (range, 0% to 45.9%) for FE casts and 3.3% (range, 0% to 15%) for EE casts. CONCLUSIONS: There was a low rate of repeat interventions (4.7%) in patients with EE casts compared with historical rates for FE casts. Improving the quality of health care involves identifying and implementing practices that provide the best outcomes at the lowest costs. The use of EE long-arm casts following closed manipulation of pediatric forearm fractures may decrease the rate of repeat manipulation or surgery compared with conventional FE casts. LEVEL OF EVIDENCE: Level IV-case series.

PURPOSE: To determine the management of torsional humeral shaft fractures in a group of expert shoulder and elbow surgeons and analyse the rate of return to sport of these throwing athletes. METHODS: A survey was sent to all physician members of two prominent sports medicine professional associations: the American Shoulder and Elbow Surgeons and the Herodicus Society. Due to the rare nature of this injury, a historical survey of management and return to play was performed to allow analysis of trends in treatment and return to play after both non-operative and operative management. RESULTS: The survey was emailed to 858 physician members. Out of the 95 respondents, 35 surgeons indicated they had treated ≥ 1 torsional humeral shaft fractures in throwing athletes (average 1.7 per surgeon). A total of 72 fractures were recorded with an average age of 20.4 years and the majority being male (68/72). Eighty-one percent (58/72) of the fractures were classified as simple spiral. Sixty-one percent (44/72) of the fractures were treated non-operatively, while 35% (25/72) of the fractures were treated by open reduction and internal fixation (ORIF). Patient age, return to sport rate and level, type of fracture, and fracture healing time did not significantly differ based on treatment type. Average time to return to sport was significantly shorter for patients who underwent ORIF compared to non-operative treatment (p = 0.001). Overall, 48 (92.3%) of the 52 athletes returned to sport, with 84% (36/43) returning to the same level of play. CONCLUSION: Torsional humeral shaft fractures in throwers are most commonly seen in young men and can be treated both operatively and non-operatively with overall similar results for healing time, rate of non-union, and return to sport. The only significant difference in the groups was an earlier return to sports in those fixed surgically, however, operative intervention also yielded a higher complication rate. Regardless of the treatment method, the overall rate of return to play was moderate. These finding are clinically relevant and can assist physicians with decision making for treatment and can help when advising throwers of appropriate expectations for recovery after this injury. LEVEL OF EVIDENCE: IV.

BACKGROUND: There are limited data reporting the outcome of patients with non-operatively managed medial malleolus fractures compared to those treated surgically in the presence of fibular stabilisation for unstable fractures of the ankle. Conservative management could result in fewer complications, reduced surgical time and lower cost. The purpose of this study is to determine if any difference exists in patient reported and surgical outcomes 1 year after surgery between operative and non-operative treatment of medial malleolar fractures in combination with stabilisation of the lateral malleolus. METHODS/DESIGN: This is a single-centre, prospective, randomised controlled trial that aims to randomise 154 participants with an unstable ankle fracture to 'non-fixation' (n = 77) or 'fixation' (n = 77) of an associated well-reduced medial malleolus fracture following fibular stabilisation. The study will include patients ≥ 16 years of age with a closed bimalleolar or trimalleolar ankle fracture who are able to consent, complete questionnaires in the English language, and complete follow-up over a 1-year period. Randomisation will occur intra-operatively when the medial malleolus fracture is deemed 'well-reduced', with 2 mm or less of fluoroscopic displacement. The technique for fixation of both the medial and lateral malleoli is at the discretion of the operating surgeon. Patient-reported, observer-rated, and radiographic assessments will be collected at baseline and then at the following post-operative assessment points: 2 weeks, 6 weeks and 1 year. Postal questionnaire outcome data will be collected at 3 and 6 months. The primary outcome measure will be the Olerud Molander Ankle Score (OMAS) at 1 year following surgery. Secondary outcome measures will include the Manchester-Oxford Foot Questionnaire (MOXFQ), EuroQol-5D (EQ-5D), pain, treatment satisfaction, time to return to activity, operative tourniquet time, and complications. DISCUSSION: There is only one previous randomised trial comparing non-fixation with fixation of associated medial malleolus fractures but that was limited by the lack of baseline patient-reported outcome data and an inferior sample size. This current prospective trial aims to provide high-quality evidence regarding the requirement for medial malleolar fixation in unstable ankle fractures.

A short cut review was carried out to establish whether functional treatment is better than conservative treatment with a below knee cast at decreasing time to functional recovery and fracture union in adults with an acute closed proximal fifth metatarsal fracture. Four papers presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. It is concluded that in proximal (zone 1 and 2) fractures of the fifth metatarsal functional treatment with immediate mobilisation is at least non-inferior to immobilisation in a cast.

A 15-year-old high school football player sustained direct impact to his anteromedial left knee by a teammate's helmet during practice. The physician referred the athlete immediately to an after-hours clinic for imaging to rule out a fracture. Radiographs of the knee showed a nondisplaced Salter-Harris type II fracture. The treating physician also ordered magnetic resonance imaging, the results of which allowed for a more specific diagnosis of the fracture as a Salter-Harris type III fracture of the left femur.J Orthop Sports Phys Ther 2019;49(3):209. doi:10.2519/jospt.2019.7984.

OBJECTIVES/HYPOTHESIS: There are limited data on laryngeal fracture presentation and management in US emergency departments (EDs). We aimed to characterize patients who are diagnosed with laryngeal fractures in the ED and identify management patterns. STUDY DESIGN: Retrospective review of the Nationwide Emergency Department Sample (NEDS) from 2009 to 2011. METHODS: The NEDS was queried for patient visits with a primary diagnosis of open or closed laryngeal fracture (International Classification of Diseases, Ninth Revision codes 807.5 and 807.6). Patient demographics, comorbidities, ED management, and hospital characteristics were extracted. RESULTS: There were 3,102 ED visits with a diagnosis of laryngeal fracture during the study period. Mean patient age was 40.9 years (range, 3-93 years). The majority of patients were male (85.5%) and sustained a closed (vs. open) fracture (91.4%), with an overall mortality rate of 3.8%. The majority of patients were treated for more than one injury during the same visit (76.2%). Most patients were evaluated at a trauma hospital (53.9%), and most patients were admitted to the hospital (71.9%). Emergent intubation or tracheostomy was rarely reported (2.6% and 0.1% of all cases), and a minority of patients underwent fiberoptic flexible laryngoscopy in the ED (1.9%). Laryngeal fractures occurred more frequently during summer months (28.2%). Mean charge for the entirety of the ED stay was $4,957.34. CONCLUSIONS: Laryngeal fracture is rare and frequently associated with other injuries. The frequency of emergent airway procedure, imaging, and flexible fiberoptic laryngoscopy is lower than expected, raising concerns about appropriate workup and management or recognition of injury in the ED setting.

BACKGROUND: The purpose of this study was to identify temporal trends in the management of pediatric femoral shaft fractures in 4- and 5-year-old children. METHODS: The Kids' Inpatient Database was used to extract data on patients aged 4 and 5 years with closed femoral shaft fractures. The frequency of nonsurgical and surgical management was calculated, and temporal trends were evaluated. RESULTS: Between 1997 and 2012, the absolute increase in surgical fixation was 35% and 58% in 4- and 5-year-old patients, respectively. The surgical rate increased every 3 years by 13.8% in 4-year-old patients and 7.6% in 5-year-old patients. Significant associations were noted based on demographics, comorbidities, and hospital characteristics with management decisions. CONCLUSIONS: A clear and significant increase was noted in internal fixation for pediatric femoral shaft fractures in 4- and 5-year-old children, and the lower age limit for surgical management of these fractures is decreasing. LEVEL OF EVIDENCE: Level III. Retrospective comparative study.

The reliable generation of consistent stabilized fractures in animal models is essential for understanding the biology of bone regeneration and developing therapeutics and devices. However, available injury models are plagued by inconsistency resulting in wasted animals and resources and imperfect data. To address this problem of fracture heterogeneity, the purpose of the method described herein is to optimize fracture generation parameters specific to each animal and yield a consistent fracture location and pattern. This protocol accounts for variations in bone size and morphology that may exist between mouse strains and can be adapted to generate consistent fractures in other species, such as rat. Additionally, a cost-effective, adjustable fracture apparatus is described. Compared to current stabilized fracture techniques, the optimization protocol and new fracture apparatus demonstrate increased consistency in stabilized fracture patterns and locations. Using optimized parameters specific to the sample type, the described protocol increases the precision of induced traumas, minimizing the fracture heterogeneity typically observed in closed-fracture generation procedures.

This study evaluated patients with displaced clavicle fractures treated surgically vs nonoperatively. The authors hypothesized that functional outcomes would be no different. A retrospective comparative study was performed of 138 patients with closed midshaft clavicle fractures. Sixty-nine patients were treated operatively and matched for sex, age, and fracture pattern to 69 patients treated nonoperatively. Charts and radiographs were reviewed, and the American Shoulder and Elbow Surgeons survey was administered. A poor outcome was defined as a treatment complication or an American Shoulder and Elbow Surgeons score less than 60. There were 116 men and 22 women with a mean age of 37.7 years and fracture patterns of 15B-1 (n=78), 15B-2 (n=48), and 15B-3 (n=12). Thirty-seven percent were tobacco smokers, with 23 treated operatively and 28 nonoperatively. Ten (14.5%) initially nonoperative patients underwent plate fixation at a mean of 25.9 weeks (range, 7-48 weeks) because of persistent pain and motion at the fracture site. Fifteen (21.7%) of the 69 patients treated acutely with surgery had 16 complications, which resulted in secondary procedures in 11 patients (15.9%). Overall, poor outcomes occurred in 21 (30.4%) of 69 after fixation and in 19 (27.5%) of 69 in the nonoperative group. Unemployment (P=.05) and tobacco use (P=.03) were associated with poor outcome, irrespective of type of treatment. Initial nonoperative treatment presents a reasonable option for many patients. No differences in complications or poor outcomes were noted for surgical vs nonoperative treatment. Social factors proved to be greater predictors of outcome than other patient or injury features. Management of clavicle fractures should be individualized with assessment of patient expectations and activity level. Social factors should also be considered. [Orthopedics. 2018; 41(5):e689-e694.].

Diaphyseal fractures of the distal humerus have a high rate of union when treated with a functional brace or an above-elbow cast (AEC). This study compares alignment of the humerus and motion of the elbow after functional brace or AEC treatment. One-hundred and five consecutive patients with a closed, extra-articular fracture of the distal humeral diaphysis were identified in the orthopedic trauma databases of 3 hospitals between 2003 and 2012. Seventy-five patients with a follow-up of at least 6 months or with radiographic and clinical evidence of fracture union were included (51 treated with functional bracing and 24 treated with an AEC). All of the fractures healed. The average arc of elbow flexion was 130° ± 9° in braced patients vs 127° ± 12° in casted patients. Four patients (8%) in the bracing group and 4 (17%) in the casting group lost >20° of elbow motion. The average varus angulation on radiographs was 17° ± 8° in braced and 13° ± 8° in casted patients, while the average posterior angulation was 9° ± 6° vs 7° ± 7°, respectively. Closed extra-articular distal diaphyseal humerus fractures heal with both bracing and casting and there are no differences in average elbow motion or radiographic alignment.

PURPOSE: Most distal radius (DR) fractures are initially managed with closed reduction and orthosis application. Mini-C-arm fluoroscopy provides assessment of reduction quality in real time. Our null hypothesis was that there would be no difference in the reduction quality of DR fractures in the emergency department when using mini-C-arm fluoroscopy during reduction compared with standard reduction techniques (evaluating reduction quality with orthogonal radiographs taken in an orthosis). METHODS: Sixty-three consecutive patients with closed DR fractures requiring reduction between April 2015 and April 2017 were prospectively randomized to standard versus fluoroscopically aided reductions. Reductions were performed by orthopedic surgery residents. The primary outcome measurement was reduction quality (radial height, radial inclination, ulnar variance, and volar tilt) as measured on postreduction radiographs. RESULTS: Standard reductions were performed in 34 patients and fluoroscopically aided reductions in 29 patients. The 2 groups were similar in regards to all potential confounders that were analyzed. No differences in postreduction radial height, radial inclination, ulnar variance, or volar tilt were noted. Overall reduction attempts and subjective difficulty of fracture reduction were increased when using fluoroscopy. The rate of initial operative management did not differ between groups. CONCLUSIONS: The use of mini-C-arm fluoroscopy during the initial closed reduction of adult DR fractures results in equivalent postreduction radiographic parameters when compared with conventional reduction techniques. Additional research regarding time spent in the emergency department and overall cost could elucidate potential benefits of fluoroscopically aided DR fracture reduction. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.

PURPOSE: The purpose of this study was to investigate the feasibility of dual magnetic resonance imaging (MRI) reporter genes, including ferritin heavy subunit (Fth) and transferrin receptor (TfR), which provide sufficient MRI contrast for in vivo MRI tracking, and the Deltex-1 (DTX1) gene, which promotes human mesenchymal stem cell (hMSC) differentiation to smooth muscle cells (SMCs), to treat closed penile fracture (CPF). METHODS: Multi-gene co-expressing hMSCs were generated. The expression of mRNA and proteins was assessed, and the original biological properties of hMSCs were determined and compared. The intracellular uptake of iron was evaluated, and the ability to differentiate into SMCs was detected. Fifty rabbits with CPF were randomly transplanted with PBS, hMSCs, Fth-TfR-hMSCs, DTX1-hMSCs, and Fth-TfR-DTX1-hMSCs. In vivo MRI was performed to detect the distribution and migration of the grafted cells and healing progress of CPF, and the results were correlated with histology. RESULTS: The mRNA and proteins of the multi-gene were highly expressed. The transgenes could not influence the original biological properties of hMSCs. The dual MRI reporter genes increased the iron accumulation capacity, and the DTX1 gene promoted hMSC differentiation into SMCs. The distribution and migration of the dual MRI reporter gene-modified hMSCs, and the healing state of CPF could be obviously detected by MRI and confirmed by histology. CONCLUSION: The dual MRI reporter genes could provide sufficient MRI contrast, and the distribution and migration of MSCs could be detected in vivo. The DTX1 gene can promote MSC differentiation into SMCs for the treatment of CPF and effectively inhibit granulation tissue formation.

BACKGROUND: This study compared the radiological outcomes of adult closed distal radius fractures (DRFs) reduction with and without fluoroscopy. We hypothesized that fluoroscopy-assisted reduction would not improve radiographic alignment or decrease the need for surgery. METHODS: Hospital medical records and radiographic images of all patients who presented with DRFs between April to June 2009 and April to June 2013 were reviewed. All patients underwent closed reduction and immobilization with or without fluoroscopic assistance. Reduction attempts were noted and pre- and postreduction posteroanterior and lateral radiographs were reviewed for fracture stability. RESULTS: Eighty-four patients underwent reduction without fluoroscopy (group 1), and 90 patients underwent reduction with the aid of fluoroscopy (group 2). According to accepted radiographic guidelines, nonsurgical treatment was indicated for 62% of patients in group 1 and 56% of patients in group 2 ( P = .44). In addition, no significant difference between the groups was observed in any postreduction radiographic parameters ( P > .53) or postreduction alignment of unstable fractures ( P = .47). CONCLUSIONS: Reduction without the use of fluoroscopy demonstrated noninferiority when compared with fluoroscopy-assisted reduction in the emergency department for closed adult DRFs.

PURPOSE: The cone beam computed tomography (CBCT) images of 2 closed treatments are compared for intracapsular condylar fractures (ICFs) to learn whether splint treatment could promote better radiologic outcomes. PATIENTS AND METHODS: Fifty-four patients with 60 sides of ICF were divided into 2 groups. In the control group (C-group), patients had a liquid diet for 1 month. In the trial group (T-group), patients wore splints with anterior elastic traction. Local CBCT images of the temporomandibular joint were obtained at T0 (mean 8.8 days), T1 (mean 37.4 days), and T3 (mean 3.3 months) after trauma. Six parameters, including 2 horizontal, 1 sagittal, and 3 vertical distances, were calculated using the coordinates of 10 points marked on CBCT sections. Statistical analysis included intragroup comparison at T0, T1, and T3, and intergroup comparison among subgroups classified by age and ICF types. RESULTS: Compared to C-group, vertical distances were significantly changed in T-group, specifically in adults and patients with ICF type B. Significant changes at stage T1 were also observed in T-group. CONCLUSION: During the natural healing process, ICF healed in the displaced position and the stump tended to move closer to the joint fossa in the vertical dimension. Splint treatment with elastic traction was helpful to increase joint space and promote better radiologic healing shape.

OBJECTIVES: Fractures comprise 3% of all emergency department (ED) visits. Although emergency physicians are often responsible for managing most of the initial care of these patients, many report a lack of proficiency and comfort with these skills. The primary objective was to assess how prepared recent emergency medicine (EM) residency graduates felt managing closed fractures upon completion of residency. Secondary objectives included whether residency training or independent practice contributed most to the current level of comfort with these procedures and which fractures were most commonly reduced without orthopedic consultation. METHODS: An anonymous online survey was sent to graduates from seven EM residency programs over a 3-month period to evaluate closed fracture reduction training, practice, and comfort level. Each site primary investigator invited graduates from 2010 to 2014 to participate and followed a set schedule of reminders. RESULTS: The response rate was 287/384 (74.7%) and included 3-year (198/287, 69%) and 4-year (89/287, 31%) programs. Practice in community, academic, and hybrid ED settings was reported by 150/287 (52.3%), 64/287 (22.3%), and 73/287 (25.4%), respectively. It was indicated by 137/287 (47.7%) that they reduce closed fractures without a bedside orthopedic consultation greater than 75% of the time. The majority of graduates felt not at all prepared (35/287, 12.2%) or somewhat prepared (126/287, 43.9%) upon residency graduation. Postresidency independent practice contributed most to the current level of comfort for 156/287 (54.4%). The most common fractures requiring reduction were wrist/distal radius and/or ulna, next finger/hand, and finally, ankle/distal tibia and/or fibula. CONCLUSIONS: Although most recent graduates feel at least "somewhat" prepared to manage closed fractures in the ED, most felt that independent practice was a greater contributor to their current level of comfort than residency training. Recent graduates indicate that fracture reduction without orthopedic consultation is common in today's clinical practice. This survey identifies common fractures requiring reduction which EM residencies may wish to consider prioritizing in their emergency orthopedic curricula to better prepare their residents for independent clinical practice.
