Aims. The aim of this study was to define the complications and long-term outcome following adolescent mid-shaft clavicular fracture. Methods. We retrospectively reviewed a consecutive series of 677 adolescent fractures in 671 patients presenting to our region (age 13 to 17 years) over a ten-year period (2009 to 2019). Long-term patient-reported outcomes (abbreviated version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) score and EuroQol five-dimension three-level (EQ-5D-3L) quality of life score) were undertaken at a mean of 6.4 years (1.2 to 11.3) following injury in severely displaced mid-shaft fractures (Edinburgh 2B) and angulated mid-shaft fractures (Edinburgh 2A2) at a minimum of one year post-injury. The median patient age was 14.8 years (interquartile range (IQR) 14.0 to 15.7) and 89% were male (n = 594/671). Results. The majority of fractures were mid-shaft (n = 606) with angulation (Edinburgh 2A2, n = 241/606, 39.8%) or displacement (Edinburgh 2B1/2, n = 263/606, 43.4%). Only 7% of the displaced mid-shaft fractures underwent acute fixation (n = 18/263). The incidence of refracture over ten years following nonoperative management of mid-shaft fractures was 3.2% (n = 19/588) and all united without surgery. Fracture type, severity of angulation, or displacement were not associated with refracture. One nonunion occurred following nonoperative management in a displaced mid-shaft fracture (0.4%, n = 1/245). Of the angulated fractures, 61 had angulation > 30°, of which 68.9% (n = 42/61) completed outcome scores with a median QuickDASH of 0.0 (IQR 0.0 to 0.6), EQ-5D-3L 1.0 (1.0 to 1.0), and 98% satisfaction with shoulder function. For the displaced fractures, 127 had displacement beyond one cortical width of bone for which completed outcome scores were provided in 72.4% (n = 92/127). Of these 15 had undergone acute fixation. Following nonoperative treatment, the median QuickDASH was 0.0 (IQR 0.0 to 2.3), EQ-5D-3L 1.0 (1.0 to 1.0), and satisfaction with shoulder function was 95%. There were no significant differences in the patients’ demography or functional outcomes between operative and nonoperative treatments. Conclusion. Nonoperative management of adolescent mid-shaft clavicle fractures results in excellent functional outcomes at long-term follow-up. Nonunion is exceptionally rare following nonoperative management and the relative indications for surgical intervention in adults do not appear to be applicable to adolescents.

A consecutive series of 150 patients with clavicular fractures is presented. In 81% detailed information regarding the mechanism of the injury was available and, of these, 94% had fractured their clavicle from a direct blow on the shoulder; only 6% had fallen on the outstretched hand. This finding, at variance with commonly held views regarding the mechanism of this injury, was further investigated by biomechanical analysis of the forces involved in clavicular fractures. The biomechanical model supported the clinical findings

We describe a patient who sustained a widely displaced, high-energy, mid-shaft clavicular fracture in association with brachial plexus damage. The distal fragment was subsequently found to have penetrated the thoracic cavity. We describe the treatment of this rare injury with a successful outcome

Aims. The primary aim of this study was to determine if delayed clavicular fixation results in a greater risk of operative complications and revision surgery. Patients and Methods. A retrospective case series was undertaken of all displaced clavicular fractures that underwent plate fixation over a ten-year period (2007 to 2017). Patient demographics, time to surgery, complications, and mode of failure were collected. Logistic regression was used to identify independent risk factors contributing towards operative complications. Receiver operating characteristic (ROC) curve analysis was used to determine if a potential ‘safe window’ exists from injury to delayed surgery. Propensity score matching was used to construct a case control study for comparison of risk. Results. A total of 259 patients were included in the analysis. Postoperative infection occurred in 3.9% of all patients (n = 10); the only variable associated was a greater time interval from injury to fixation (p = 0.001). Failed primary surgery requiring revision fixation was required in 7.7% of the cohort (n = 20), with smoking (p < 0.001), presence of a postoperative infection (p < 0.001), increasing age (p = 0.018), and greater time delay from injury to surgery (p = 0.015) identified as significant independent predictors on regression analysis. ROC analysis revealed that surgery beyond 96 days from injury increased the rate of major complications and revision surgery. Using a matched case cohort of cases before (n = 67) and after (n = 77) the ‘safe window’, the risk of postoperative infection increased (odds ratio (OR) 7.7, 95% confidence interval (CI) 1.9 to 62.9; p = 0.028), fixation failure (OR 3.8, 95% CI 1.2 to 12.1; p = 0.017) and revision surgery (OR 4.8, 95% CI 1.5 to 15.0; p = 0.004). Conclusion. A delay to primary fixation of up to three months following injury may be acceptable, beyond which there is an increased risk of major operative complications and revision surgery.

Fractures of the clavicle are relatively common, occurring mostly in younger patients and have historically been managed non-operatively. Recent studies have shown an advantage to surgical reduction and stabilisation of clavicle fractures with significant displacement. Currently, fracture displacement is measured using simple anterior-posterior two-dimensional x-rays of the clavicle. Since displacement can occur in all three-dimensions, however, evaluation of the amount displacement can be difficult and inaccurate. The purpose of this study was to determine the view that provides the most accurate assessment. Nine CT scans of acute displaced clavicle fractures were analysed with AmiraDEV5.2.2 Imaging software. Measurements for degrees of shortening and fracture displacement of the fracture clavicle were taken. Using a segmentation and manipulation module (ITK toolkit), five digitally reconstructed radiographs (DRRs) mimicking antero-posterior x-rays were created for every CT, with each differing by projection angle (ranging from 20° upwards tilt to 20° downwards tilt). Measurements were taken on each DRR using landmarks of entire clavicle length, distance from vertebrae to fracture (medial fragment length), distance from fracture to acromium (lateral fragment length), and horizontal shortening, and then compared to the true measurement obtained from the original CT. For all 9 samples, after comparing the measurements of clavicle fracture displacement in each 2D image, we found that an AP view with a 20° downward tilt yielded displacement measurements closest to the 3D (“gold standard”) measurements. The results agree with previous data collected from cadaveric specimens using physical X-ray film images. DDRs enable creation of multiple standard AP radiographs from which accurate tilt can be measured. The large deviation in measurements on different DRR projections motivates consideration of standardising X-ray projections. A uniform procedure would allow one to correctly evaluate the displacement of clavicular fractures if fracture displacement information is to be utilized in motivating surgical decision-making

Purpose: The purpose of this study is to evaluate the biomechanical properties and the stability between locking clavicle plate, dynamic compression plate and external fixation systems on an unstable displaced fracture model under torsional and 3 point bending loading.

Materials and Methods: Forty eight human adult formalin fixed clavicles were paired according to their BMD (DEXA) homogeneously into three groups; Group 1: Locking clavicle plate, Group 2: Dynamic compression plate and Group 3: External fixator. Each specimen was then osteotomized in the midshaft; and a 5mm bone segment was removed in order to stimulate a displaced fracture model. Biomechanical tests were applied in a cyclic loading model in MTS, Bionix 2. Torsional and three point bending forces were performed for 1000 cycles in all subgroups, stiffness was recorded at 10 cycles (initial) and periodic every 100 cyclic intervals. Failure load and moment were obtained after 1000 cycles. Initial stiffness, failure loads and the percentage of initial stiffness for each subgroup were compared across each group. One-way ANOVA and Bonferoni post- hoc tests were utilized to determine which were significantly different from one another with the significance level set as p< 0.05.

Results: The mean initial stiffness(Nmm/deg) - mean failure moments(Nmm) for torsional tests were 703.2 – 7671.7 (locking plate), 448.1 – 4370.3 (compression plate), 365.2 – 2999.7 (ex-fix) and the mean initial stiffness(Nmm) – mean failure loads(N) for bending tests were 32.6 – 213.2 (locking plate), 23.4 – 131.1 (compression plate), 20.6 – 102.7 (ex-fix) respectively. ANOVA test confirmed an overall significant difference between the three constructs in terms of both failure loads and a significant difference only between locking plate and others in terms of initial stiffness. At all cyclic intervals after 100 cycles there was significant difference of percentage of initial stiffness between locking plate and others in bending and torsion. There was a significant difference between compression plate and ex-fix after 700 cycles in torsional group and no difference found in bending group between (any of) them at any cyclic interval.

Conclusions: Locking anatomic clavicle plate is significantly more stable than unlocked dynamic compression plate and external fixator under torsional and bending cyclic loading in an unstable displaced fracture or non-union clavicle model.

Aims. It is unclear whether acute plate fixation facilitates earlier return of normal shoulder function following a displaced mid-shaft clavicular fracture compared with nonoperative management when union occurs. The primary aim of this study was to establish whether acute plate fixation was associated with a greater return of normal shoulder function when compared with nonoperative management in patients who unite their fractures. The secondary aim was to investigate whether there were identifiable predictors associated with return of normal shoulder function in patients who achieve union with nonoperative management. Methods. Patient data from a randomized controlled trial were used to compare acute plate fixation with nonoperative management of united fractures. Return of shoulder function was based on the age- and sex-matched Disabilities of the Arm, Shoulder and Hand (DASH) scores for the cohort. Independent predictors of an early recovery of normal shoulder function were investigated using a separate prospective series of consecutive nonoperative displaced mid-shaft clavicular fractures recruited over a two-year period (aged ≥ 16 years). Patient demographics and functional recovery were assessed over the six months post-injury using a standardized protocol. Results. Data from the randomized controlled trial consisted of 86 patients who underwent operative fixation compared with 76 patients that united with nonoperative treatment. The recovery of normal shoulder function, as defined by a DASH score within the predicted 95% confidence interval for each respective patient, was similar between each group at six weeks (operative 26.7% vs nonoperative 25.0%, p = 0.800), three months (52.3% vs 44.2%, p = 0.768), and six months post-injury (86.0% vs 90.8%, p = 0.349). The mean DASH score and return to work were also comparable at each timepoint. In the prospective cohort, 86.5% (n = 173/200) achieved union by six months post-injury (follow-up rate 88.5%, n = 200/226). Regression analysis found that no specific patient, injury, or fracture predictor was associated with an early return of function at six or 12 weeks. Conclusion. Return of normal shoulder function was comparable between acute plate fixation and nonoperative management when union was achieved. One in two patients will have recovery of normal shoulder function at three months, increasing to nine out of ten patients at six months following injury when union occurs, irrespective of initial treatment.

In an osteological collection of 3100 specimens, 70 were found with unilateral clavicular fractures which were matched with 70 randomly selected normal specimens. This formed the basis of a study of the incidence of arthritis of the acromioclavicular joint and the effect of clavicular fracture on the development of arthritis in the ipsilateral acromioclavicular joint. This was graded visually on a severity scale of 0 to 3. The incidence of moderate to severe arthritis of the acromioclavicular joint in normal specimens was 77% (100 specimens). In those with a clavicular fracture, 66 of 70 (94%) had arthritis of the acromioclavicular joint, compared to 63 of 70 (90%) on the non-injured contralateral side (p = 0.35). Clavicles with shortening of 15 mm or less had no difference in the incidence of arthritis compared to those with shortening greater than 15 mm (p = 0.25). The location of the fracture had no effect on the development of arthritis

Aims. To compare the functionality of adults with displaced mid-shaft clavicular fractures treated either operatively or nonoperatively and to compare the relative risk of nonunion and reoperation between the two groups. Methods. Based on specific eligibility criteria, 120 adults (median age 37.5 years (interquartile range (18 to 61)) and 84% males (n = 101)) diagnosed with an acute displaced mid-shaft fracture were recruited, and randomized to either the operative (n = 60) or nonoperative (n = 60) treatment group. This randomized controlled, partially blinded trial followed patients for 12 months following initial treatment. Functionality was assessed by the Constant score (CS) (assessor blinded to treatment) and Disability of the Arm, Shoulder and Hand (DASH) score. Clinical and radiological evaluation, and review of patient files for complications and reoperations, were added as secondary outcomes. Results. At 12 months, 87.5% of patients (n = 105) were available for analysis. The two groups were well balanced based on demographic and fracture-related characteristics. At six weeks of follow-up a significant difference in DASH score (p < 0.001) was found in favour of operative treatment. The functionality at 12 months of follow-up based on CS and DASH was excellent in both groups (CS > 90 points and DASH < 10 points) with no significant difference (p = 0.277 for DASH and p = 0.184 for CS) between the two groups. The risk of symptomatic nonunion was significantly higher in the nonoperative group (p = 0.014), with a relative risk of 9.47 (95% confidence interval (CI) 1.26 to 71.53) in this group compared to the operative group. The number-needed-to-treat to avoid one symptomatic nonunion was 6.2. Initial treatment and age were factors significantly associated with nonunion in a logistic analysis. There were 26% in both groups (n = 14 in operative group and n = 15 in nonoperative group) who required secondary surgery, with most indications in the nonoperative group mandatory due to nonunion compared to most relative indications in the operative group requiring intervention due to implant irritation. Conclusion. Superiority was not identified with either an all-operative or all-nonoperative approach. The functionality at short term (within six weeks) seems igreater following operative treatment but was not found at one year. The risk of nonunion is significantly higher with nonoperative treatment. However, an all-operative approach to lower the nonunion risk may result in unnecessary surgery and is not recommended.

Clavicular hook plates have been used over the last decade in the treatment of lateral clavicular fractures with good rates of union reported throughout the literature. Fewer studies have reported the functional outcome of these patients and some have reported potential soft tissue damage post plate removal. We aimed to review the functional outcomes alongside union rates in patients treated with hook plates for lateral clavicular fractures. In this retrospective case series, 21 patients with traumatic lateral third clavicular fractures were included. 15 had Neer type II fractures, 4 Neer type III fractures, 1 patient had a Neer type I fracture and 1 radiograph was not able to be classified. All patients were treated with clavicular hook plates at the same district general hospital by five experienced surgeons between March 2010 and February 2015 adhering to the same surgical protocol. All patients had standard physiotherapy and post operative follow up. Plates were removed when radiological union was achieved in all but one patient who had the plate removed before union was achieved due to prolonged non-union. Patients were followed up post plate removal and evaluated clinically using the Oxford Shoulder Score. Their post plate radiographs were assessed by an independent radiologist and bony union documented. 21 patients were included. Mean age was 40 (range 14–63) with a male:female ratio of 17:4. Mean follow up was 5 months post injury (1–26 months). The hook plate remained in situ for a mean time of 4.3 months (2–16 months). One patient developed a post-operative wound infection treated with antibiotics, 2 patients developed adhesive capsulitis, one patient had not achieved bony union prior to hook plate removal at 16 months, however did achieve union 2 months post plate removal, two patients required revision plating. All patients achieved bony union eventually with good alignment and no displacement of the acromioclavicular joint seen on the most recent post operative radiographs. Post plate removal Oxford Shoulder Scores indicated good shoulder function with a mean score of 41.5 (maximum score possible 48 and the range of scores for our cohort was 30–47). Our data would support the use of hook plates in the treatment of lateral clavicular fractures. All patients achieved union eventually with good alignment and this was reflected in the good functional outcome scores. This study is limited in its small cohort and short-term follow up. More research is required to examine the long term consequences of hook plate surgery in a larger patient population

Osteoarthritis (OA) is the most common disorder of the Sternoclavicular Joint (SCJ). In our case-control study, we evaluated the relationship between clavicular length and OA at the SCJ. CT scans of adults presenting to the Emergency Department of our hospital were examined to look for OA, defined as the presence of osteophytes, subchondral cysts, or cortical sclerosis at the SCJ. Medial-most and lateral-most points of the clavicle were marked on the slices passing through the SC and AC joints respectively. Using x, y, and z-axis coordinates from the DICOM metadata, clavicular length was calculated as the distance between these two points with 3D geometry. Preliminary data of 334 SCJs from 167 patients (64% males, 36% females) with a mean age of 48.5 ± 20.5 years were analysed. Multivariate regression models revealed that age and clavicular length were independent risk factors for OA while gender did not reach statistical significance. A 1mm increase in length was associated with 9% and 7% reduction in the odds of developing OA on the left and the right respectively. Comparing the mean clavicular length using t-test showed a significantly shorter clavicle in the group with OA (145.8 vs 152.7, p=0.0001, left and 144.2 vs 150.3, p=0.0007, right). Our data suggest that the risk of developing OA at the SCJ is higher for shorter clavicles. This could be of clinical relevance in cases of clavicular fracture where clavicular shortening might lead to a higher risk of developing OA. Biomechanical studies are needed to find out the mechanism of this effect

Introduction: Mid-shaft clavicular fractures that are displaced and shortened are often treated surgically. The standard technique in the past has been to use plate fixation. However, in the last five years intramedullary fixation has been popularised. To our knowledge no recent study has compared the outcomes of intramedullary pinning and plating of displaced mid-shaft clavicular fractures. Method: We retrospectively evaluated 40 patients with mid-shaft clavicular fractures. Twenty patients had plate fixation and twenty patients had intramedullary fixation for exactly the same fracture pattern. Each patient filled out a standardised questionnaire particular to clavicular fractures and was assessed using the Shoulder Score Index of the American Shoulder and Elbow Surgeons and the Constant Score. A physical examination was performed and individual radiographs were assessed to determine the state of union. Results: All fractures that were treated with intramedullary pin fixation went on to union within two to three months. There was one nonunion in the plate fixation group requiring revision surgery. The results revealed no significant difference in the functional outcome scores. There were however fewer complications, less scar related paraesthesia, shorter stay in hospital, and earlier mobilization in the group who underwent intramedullary pinning. Conclusions: Our results suggested that both techniques of intramedullary pinning and plating resulted in good long-term functional outcomes for patients with acute mid-shaft clavicular fractures. Intramedullary pinning, however, resulted in fewer short-term complications. From this study the method of fixation for mid-shaft clavicle fractures should be determined by the surgeon’s preference and expertise

To estimate the prevalence of clavicular fractures, number of cases required operative treatment, and whether removal of the implant is a frequent necessity. Between November 2005 and Nov 2007 all patients presenting in our institution with clavicular fractures were eligible for participation. Patients below 18 years of age, and pathological fractures were excluded. Retrospective review of clinical notes and radiographs. Demographic details, mode of injury, treatment protocol, operative procedures performed, time to union, complications post-surgery stabilization, and the number of cases that required implant removal were documented and analysed in a computerized database. The mean time of follow up was 24 weeks (12–48). Out of 16,280 adult fractures that presented to our institution, 200 (1.23%), (137 males) patients met the inclusion criteria with a mean age of 43 years (19–95) and a mean ISS of 9 (4–38). There were 4 of the medial, 153 of the middle and 43 of the lateral clavicle fractures (3 were open). 178 (89%) patients were treated non-operatively and 22 (11%) operatively. Indications for surgery included open fracture, bony spike/skin threatened, grossly displaced/comminuted fracture, polytrauma and non-union. Mean time to radiological union was 14 weeks (5–38 weeks). Out of the 200 patients 12 (6%) developed non-union. Out of the 22 operated patients, 7 (32%) required plate removal and 1 had screw removal. Indications for removal of implant included, periprosthetic fracture (1), prominent metal work through skin (3), pain in shoulder (2), pressure symptoms (1). Post removal of implant, 6 (75%) patients claimed improvement in symptoms. Functional outcome was excellent/good in 90% of cases. The incidence of clavicular fractures was 1.23%. A small number of patients (11%) required operative treatment out of which one third had metal work removal. The majority of clavicular fractures can be treated non-operative with good functional results

The August 2014 Children’s orthopaedics Roundup. 360 . looks at: Conservative treatment still OK in paediatric clavicular fractures; Femoral anteversion not the usual suspect in patellar inversion; Shoulder dislocation best treated with an operation; Perthes’ disease results in poorer quality of adult life; Physiotherapy little benefit in supracondylar fractures; Congenital vertical talus addressed at the midtarsal joint; Single-sitting DDH surgery worth the effort; and cubitus valgus associated with simple elbow dislocation

Purpose. The evolution of locked anatomical clavicular plating in combination with evidence to suggest that fixation of clavicle fractures yields better outcome to conservative treatments has led to an increasing trend towards operative management. There is no evidence however to compare early fixation with delayed reconstruction for symptomatic non- or mal-union. We hypothesize that early intervention yields better functional results to delayed fixation. Methods. Between August 2006 and May 2010, 97 patients were managed with operative fixation for their clavicular fracture. Sixty eight with initial fixation and 29 delayed fixation for clavicular non- or mal-union. Patients were prospectively followed up to radiographic union, and outcomes were measured with the Oxford Shoulder Score, QuickDASH, EQ5D and a patient interview. Mean follow-up was to 30 months. All patients were managed with Acumed anatomical clavicular plates. Results. The radiographic and clinical outcomes were available for all patients. Scores were available for 62 (62/97). There were no statistically significant differences in age (p>0.05), sex (p>0.05), energy of injury (p>0.05), number of open fractures (p>0.05) between the two groups. The mean quickDASH was 8.9 early, 9.1 delayed (p< 0.05), Oxford Shoulder score was 15.7 early, 16.1 delayed (p< 0.05). In the early fixation group 5 patients had wound healing complications, and 8 went on subsequently to have removal of prominent metalwork. In the delayed fixation group 2 had wound healing complications and 4 had removal of prominent metalwork. There were no statistically significant differences in the EQ5D quality of life questionnaire. Conclusion. There are no statistically significant differences in shoulder performance, wound or operative complications between early and delayed fixation of clavicular fractures. Our series does not support early fixation of clavicular fractures, as results for delayed intervention in those who become symptomatic appear comparable

Both conservative and operative forms of treatment have been recommended for patients with a ‘floating shoulder’. We compared the results of conservative and operative treatment in 25 patients with this injury and investigated the use of the glenopolar angle (GPA) as an indicator of the functional outcome. A total of 13 patients (ten male and three female; mean age 32.5 years (24.7 to 40.4)) were treated conservatively and 12 patients (ten male and two female; mean age 33.67 years (24.6 to 42.7)) were treated operatively by fixation of the clavicular fracture alone. Outcome was assessed using the Herscovici score, which was also related to changes in the GPA at one year post-operatively. The mean Herscovici score was significantly better three months and two years after the injury in the operative group (p < 0.001 and p = 0.003, respectively). There was a negative correlation between the change in GPA and the Herscovici score at two years follow-up in both the conservative and operative groups, but neither were statistically significant (r = -0.295 and r = -0.19, respectively). There was a significant difference between the pre- and post-operative GPA in the operative group (p = 0.017). When compared with conservative treatment, fixation of the clavicle alone gives better results in the treatment of patients with a floating shoulder. The GPA changes significantly with fixation of clavicle alone but there is no significant correlation between the pre-injury GPA and the final clinical outcome in these patients.

Introduction. Clavicle fractures can cause pain and functional impairment if not managed appropriately. This paper evaluates the prevalence of clavicular fractures, estimates number of cases requiring operative treatment, whether removal of implant is a frequent necessity and compares the final functional outcome of the operative and non-operative group. Materials/Methods. Between November 2005 and November 2007 patients with clavicular fractures were eligible for participation. Patients below 18 years of age, and pathological fractures were excluded. Operative versus non-operative treatment, radiographic classification (Allman system), complications, implant removal, and functional outcome using the University of California Los Angeles (UCLA) shoulder scores were documented and analysed. Results. Out of 16,280 fractures presenting to our University Teaching Hospitals, 200 (1.23%) met the inclusion criteria. Twenty patients were lost due to natural attrition, 159 (88.3%) patients were treated non-operatively and 21 (11.7%) patients operated upon, over half for symptomatic non-union. All clavicles united post operatively. Eighty one conservatively managed undisplaced medial, middle and lateral end fractures had excellent mean UCLA shoulder scores. A statistical significance in UCLA scores (p<0.05) was noted between the operative and non-operative groups in mid shaft fractures. Under half (42.9%) required removal of metal implant sue to soft tissue irritation with complete resolution of symptoms. Conclusion. The incidence of clavicle fractures was 1.23%. A small number of patients (11.7%) required operative treatment. We recommend surgical management of symptomatic non-union and removal of metal implant for hard ware related symptoms
