Aims. Distal third clavicle (DTC) fractures are increasing in incidence. Due to their instability and nonunion risk, they prove difficult to treat. Several different operative options for DTC fixation are reported but current evidence suggests variability in operative fixation. Given the lack of consensus, our objective was to determine the current epidemiological trends in DTC as well as their management within the UK. Methods. A multicentre retrospective cohort collaborative study was conducted. All patients over the age of 18 with an isolated DTC fracture in 2019 were included. Demographic variables were recorded: age; sex; side of injury; mechanism of injury; modified Neer classification grading; operative technique; fracture union; complications; and subsequent procedures. Baseline characteristics were described for demographic variables. Categorical variables were expressed as frequencies and percentages. Results. A total of 859 patients from 18 different NHS trusts (15 trauma units and three major trauma centres) were included. The mean age was 57 years (18 to 99). Overall, 56% of patients (n = 481) were male. The most common mechanisms of injury were simple fall (57%; n = 487) and high-energy fall (29%; n = 248); 87% (n = 748) were treated conservatively and 54% (n = 463) were Neer type I fractures. Overall, 32% of fractures (n = 275) were type II (22% type IIa (n = 192); 10% type IIb (n = 83)). With regards to operative management, 89% of patients (n = 748) who underwent an operation were under the age of 60. The main fixation methods were: hook plate (n = 47); locking plate (n = 34); tightrope (n = 5); and locking plate and tight rope (n = 7). Conclusion. Our study is the largest epidemiological review of DTC fractures in the UK. It is also the first to review the practice of DTC fixation. Most fractures are being treated nonoperatively. However, younger patients, suffering a higher-energy mechanism of injury, are more likely to undergo surgery. Hook plates are the predominantly used fixation method followed by locking plate. The literature is sparse on the best method of fixation for optimal outcomes for these patients. To answer this, a pragmatic RCT to determine optimal fixation method is required.

Background. A number of studies have described the epidemiological characteristics of clavicle fractures, including two previous reports from our institution. The Robinson classification system was described in 1998, after the analysis of 1,000 clavicle fractures. Aims. We aim to provide a contemporary analysis and compare current clavicle fracture patterns of our adult population with historical reports. Methods. A retrospective analysis of a prospectively collected fracture database from an institution serving 598,000 was conducted over a 12 month period, beginning July 2007. Demographic data were recorded prospectively for each patient presenting with an acute clavicle fracture including age, gender, mode of injury, fracture classification, and the presence of associated skeletal injuries. Fractures were classified according to the Robinson Classification system. Results. A total of 312 clavicle fractures were identified, occurring with an incidence of 55.9/100,000/yr (CI 49.8–62.5) and following a bimodal male and unimodal older female distribution. Sporting activity and a simple fall from standing caused the majority of injuries. An association between age, mode of injury and fracture type was observed, with younger patients sustaining high energy injury associated with majority of the Type II midshaft fractures; whilst more than fifty-nine percent of Type III lateral one third fractures occur in elderly patients as a result of simple fall. Overall, Type II midshaft fractures remain the most common, but comparison of this series with historical data reveals that the epidemiology of clavicle fractures is changing. Conclusions. We have identified an increase in the average patient age and overall incidence of clavicle fractures in our adult population. The incidence, relative frequency, and average patient age of Type III lateral one-fifth fractures have increased. This epidemiological trend has implications for the future management of clavicle fractures in our region

Twenty fresh-frozen clavicles were fractured and randomized to one of four fixation techniques. Three plates were used: the LCP (locking compression plate), LCDCP (low contact dynamic compression plate) and Recon (pelvic reconstruction plate). One intramedullary device was used (the Rockwood Clavicle Pin). The constructs were tested for stiffness in bending and torque modes and ultimate strength in bending. The three plates were significantly stiffer then the Pin. Of the three plates, the Recon was significantly less stiff and weaker in ultimate strength then the LCP and LCDCP plates. This study was conducted to compare and evaluate different fixation techniques for clavicle fractures. Plate fixation with LCP (locking compression plate), LCDCP (low contact dynamic compression plate) and Recon (reconstruction plate) is stiffer then Pin fixation. The Recon plate was weaker and less stiff then the other two plates. Fractures of the clavicle are common and account for approximately 5–10% of all fractures and represent 35–45% of shoulder girdle fractures. Open reduction, internal fixation is becoming a standard for more clavicle fractures with the recognition of the limitations of non-operative management. There is a great disparity in biomechanical literature on clavicle fixation. The average bending stiffness compared to the intact clavicles for each construct was: Recon=104%, LCDCP=124%, LCP=122%, and Pin=69%. The average torque stiffness for each construct was: Recon=83%, LCDCP=91%, LCP=99%, and Pin=46%. The three plate constructs provided significantly more rigid fixation in both bending and torque testing then the clavicle pin (p< 0.05). Ultimate bending strength for each construct was: Recon=8.5 Nm, LCDCP=21.3 Nm, LCP=21.8 Nm, and Pin=15.8 Nm. The Recon plate was significantly weaker the three other constructs (p< 0.05). Twenty fresh frozen cadaver clavicles were randomized to one of the four fixation groups. An Instron materials testing machine was used to compare the fixation constructs. Each clavicle was tested for its bending and torque stiffness. Following construct stiffness testing, all samples were brought to their ultimate failure strength with a superior bending load. This study has shown that plate fixation of clavicle fractures yields stiffer constructs then pin fixation. However, plate fixation requires extensive dissection and stripping of the periclavicular soft tissue and may result in prominent hardware. In fracture situations with significant comminution, the LCP and LCDCP offer significantly greater fracture fixation then the reconstruction plate.

Purpose. In a previously published multicenter randomized clinical trial it was shown that young patients (16–60 years-old) with displaced mid-shaft clavicle fractures had superior limb specific outcomes when they were treated with primary plate fixation versus non operative treatment at one year follow-up. This study examines the general health status of this cohort of patients at two-years post injury. Method. We evaluated the general health of a cohort of patients with displaced mid-shaft clavicle fractures comparing non-operative versus plate fixation at two-years after injury. At the conclusion of our study, eighty-nine patients (fifty-four from the operative group and thirty-five from the non-operative group) completed the two-year follow-up. Outcome analysis included the standard clinical follow-up and SF-36 scores. Results. SF-36 scores were significantly improved in the operative fixation group at all time-points: 6 weeks, 3, 6, 12, 24 months (P<0.01). At two-years after the injury, the patients in the operative group had better patient oriented outcome scores, especially in the physical performance component of the SF-36 scores (Physical component (PCS) 57.1 versus 51.0, P<0.05). Conclusion. Operative treatment more reliably restored pre-operative levels of general health status compared to non-operative treatment. Operative fixation of a displaced mid-shaft clavicle fracture in young active patients resulted in improved patient oriented general health status at two-year follow-up. The improvement is especially pronounced in the physical component of the SF-36 scores. These findings support primary plate fixation of displaced mid-shaft clavicle fractures in young active adults

Clavicle fractures represent 45% of all shoulder girdle injuries. Although clavicle fractures are usually readily recognisable and unite uneventfully with treatment, they can be associated with difficult early and late complications. Fractures of the middle third of the clavicle represent 80% of all clavicular fractures. Traditionally clavicle fractures are treated conservatively, with surgical treatment reported as being associated with an increased rate of complications. Indications for primary open fixation include significant displacement, fracture comminution and tenting of the skin, threatening its integrity which fail to respond to closed reduction. What constitutes significant displacement, is usually not defined; nor is consideration for open reduction of displaced fractures, which are not comminuted and do not threaten the integrity of the overlying skin. This paper reports on the technique indications and use of the “Rockwood Intramedullary Clavicle Pin” and the results achieved using this technique

Purpose: To document outcomes and patient satisfaction in relation to the incision used following clavicle fracture fixation. In literature, the incidence of incisional numbness following operative fixation of clavicle fractures is reported to be between 7–29%. Such wound related problems contribute significantly to the dissatisfaction of patients with operatively treated clavicle fractures. Wound related problems can be bothersome and disabling and this is poorly documented. Method: All primary clavicle fractures treated with plating at the Alfred Hospital between 01/06/2003 and 01/06/2006 were included in the study. Patients were asked to complete paper-based questionnaires assessing satisfaction, pain, scar satisfaction, presence of numbness and the degree of disability following clavicle fixation. Their clinical notes and X-rays were reviewed for evaluation. The study sample was then divided into two groups; horizontal incision versus vertical incision then the data was analysed. Results: The response rate was 65% (35/54). 74% of patients reported as having “good” or better outcome following their clavicle fracture fixation. There was no statistically significant difference in pain scores. However, there were statistically significant differences observed in the presence of numbness (vertical 21% versus horizontal 62%) and the disability from the numbness between the two incision types. Overall satisfaction between the two groups was also significantly different. Conclusion: This study confirms that scar-related problems significantly affect the satisfaction following plating of clavicle fractures and numbness appears to be one of the most significant factors. Vertical incisions appear to reduce the incidence of numbness and lead to better patient satisfaction. Our results suggest that vertical incision is an attractive alternative approach in clavicle fracture fixation

Purpose. Plating remains the most widely employed method for the fixation of displaced diaphyseal clavicle fractures. The purpose of this study was to assess the efficacy and outcomes of diaphyseal clavicle fractures treated with intramedullary fixation using the Rockwood clavicle pin. Methods. We conducted a retrospective analysis of all diaphyseal clavicle fractures treated with intramedullary fixation using the Rockwood pin between February 2004 and March 2010. Sixty-eight procedures were carried out on 67 patients. Functional outcome was assessed using the Disability of the Arm, Shoulder and Hand (DASH) questionnaire and an overall patient satisfaction questionnaire. Results. There were 52 (77.6%) male and 15 (22.4%) female patients with an average age of 35.8 years. In 35 (51.5%) cases the injury was located on the dominant side. Fractures were classified according to the Edinburgh system with the commonest configuration being the Type 2B1 (47, 69.1%). The indications for fixation were; acute management of displaced fractures (56, 82.4%), delayed union (2, 2.9%), nonunion (8, 11.8%) and malunion (2, 2.9%). The average time to pin removal was 3.7 months and the average follow-up prior to discharge was 6.9 months. Sixty-six (97.1%) fractures united without consequence. Two (2.9%) cases of non-union were treated with repeat fixation using a contoured plate and bone graft. The most common problem encountered postoperatively was discomfort due to subcutaneous pin prominence posteriorly (12, 17.6%) which resolved following removal of the metalwork. The average DASH score was 6.04 (0–60) and 96.4% of patients rated their satisfaction with the procedure as good to excellent. Conclusion. Due to its minimally invasive technique, cosmetically favourable scar, preservation of periosteal tissue, avoidance of stress risers associated with screw removal and good clinical outcomes, the use of this device is the preferred method of treatment for displaced diaphyseal clavicle fractures in our hospital

Aims. The aim of this study was to compare biomechanical properties of pre-contoured plate fixation using different screw fixation modes in a mid-shaft clavicle fracture model. Methods. Fourth generation biomechanical clavicle sawbones with a mid-shaft osteotomy were plated in one of three modes: nonlocking bicortical, locking bicortical and locking unicortical mode. The specimens were then tested to failure in four-point bending and pull-off tests. Results. Failure due to fracture through the sawbone was more common in nonlocking bicortical mode while plate bending was more common in the locking bicortical group. The ultimate load at failure was significantly lower in the locking bicortical group compared to the nonlocking bicortical group, however there was no significant difference between the locking unicortical group and nonlocking bicortical group. In the pull-off tests 100% of nonlocking bicortical and locking bicortical plates failed by fracture of the sawbone. 100% of the locking unicortical plates failed by plate and screw pull-off from the sawbone. The load at failure was highest for the locking unicortical plate but this was not significantly different to the other groups. Conclusion. This study shows that specimens fixed with locking unicortical screw fixation withstood comparable or superior loads in four-point bending and pull-off test when compared to nonlocking bicortical and locking bicortical screw fixation. In addition both locking screws and unicortical screws appear to provide a protective effect against periprosthetic sawbone fracture. Locking unicortical screw fixation of pre-contoured plates may be a viable alternative in the fixation of mid-shaft clavicle fractures

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

Background. This is a continued assessment of the effectiveness of a locked intramedullary device in the treatment of acute clavicle shaft fractures. Results of patients treated thus far were assessed, including patients reported on previously. Description of methods. Patients admitted with midshaft clavicle fractures were assessed to determine whether operative fixation of the fracture was required. Indications for surgery were midshaft clavicle fractures with 100% displacement; more than 1.5 cm of shortening, presence of a displaced butterfly segment, bilateral clavicle fractures, ipsilateral displaced glenoid neck fractures, skin and neurovascular compromise. Patients that matched the criteria for surgery were treated operatively with an intramedullary locked device by the author. Post-operatively, patients were kept in a shoulder immobilizer for a period of 6 weeks. Patients were invited to attend a scheduled follow-up visit where the data was collected that comprised the review. All patients were assessed by the surgeon, a radiologist, a physiotherapist and an occupational therapist. Scar size and quality, Dash score, Constant Shoulder score, complications and the radiological picture were assessed. Summary of results. 50 patients (52 clavicle fractures – 2 patients sustained bilateral fractures), 28 males and 22 females with a mean age of 30 attended the schedule data collection visit and were included in the study. 48 clavicles achieved complete union with the remaining 4 fractures progressing normally to union at 10 and 12 weeks post surgery. No additional complications than those reported on previously were encountered. Conclusion. Locked intramedullary fixation of clavicle shaft fractures that match the criteria for operative fixation continues to give good results. No non-unions were found and a high level of patient satisfaction was achieved. The operative technique continues to be refined leading to less fixation related complications. MULTIPLE DISCLOSURES

Fracture of the clavicle is common and comprise 4% of all adult fractures. The incidence appears to be increasing owing to several factors, including the occurrence of many more high velocity vehicular injuries and an increase in popularity of contact sports. The most common side site for occurrence of fracture in clavicle is the middle third and the medial fractures are rare. We did our retrospective study during 2003–2005. We review 13 patients with fracture of the clavicle. There were 10 males and 3 females and 11 were left side and 2 were right side. Patients ages ranged between 15–49 years (average 29.6). The majority of fractures were caused by motorbike and quads bike accidents. 10 were classified as Neer type 1 (midshaft) and 3 were Neer type 1 (distal third). All these patients were treated with an Acumed congruent anatomical plate. The patients were followed up for 6 months to 1 years. Post-operatively patients were treated for 3 weeks in a sling, and then had physiotherapy for the next 3 weeks. All fractures were united by 7 weeks. Our complications were 1 superficial wound infection, 1 delayed union at 9 weeks, and 1 non union at 12 weeks. All patients had a full range of movement of the shoulder by the end of the 6. th. week. In the past fractures of the clavicle were treated conservatively. Currently patients want to mobilise their limbs early, and get back to work. The clinical results of the congruent anatomical plate appear to be good in terms of fracture union and early return to function in young patients. The principal advantage of this method of treatment is an anatomical reduction of the fracture and early rehabilitation with return to normal function

This prospective evaluation of early experience using this technique. Patients with fracture of the distal clavicle were surgically treated with clavicular hook plate fixation. They were reviewed clinically and radiographically by one observer.

12 patients, 7 male, 5 female, were treated in our unit. Mean age (34.7) range 25–60 years. 10 were the results of low velocity injury.

9 were treated within one week of injury. 3 were treated at 13, 14 and 16 weeks post injury. Mean hospital stay 2.7 range 2–5 days. All patients healed, 10 within 12 weeks. All resumed full activity by 24 weeks. 2 had superficial wound infection, treated successfully with oral antibiotics without implant removal. One had a seroma, which resolved spontaneously. One patient developed limitation of movement at 20 weeks ultrasound confirmed impingement. Plate was removed and patient regained full range of movement after six weeks. No implant fracture or loosening was observed.

Based on experience to date the clavicular hook plate is a safe and reliable method of fixation. Relatively simple implant with good results. Allows early mobilisation and has little complication.

Aims. The management of mid-shaft clavicle fractures (MSCFs) has evolved over the last three decades. Controversy exists over which specific fracture patterns to treat and when. This review aims to synthesize the literature in order to formulate an appropriate management algorithm for these injuries in both adolescents and adults. Methods. This is a systematic review of clinical studies comparing the outcomes of operative and nonoperative treatments for MSCFs in the past 15 years. The literature was searched using, PubMed, Google scholar, OVID Medline, and Embase. All databases were searched with identical search terms: mid-shaft clavicle fractures (± fixation) (± nonoperative). Results. Using the search criteria identified, 247 studies were deemed eligible. Following initial screening, 220 studies were excluded on the basis that they were duplicates and/or irrelevant to the research question being posed. A total of 27 full-text articles remained and were included in the final review. The majority of the meta-analyses draw the same conclusions, which are that operatively treated fractures have lower nonunion and malunion rates but that, in those fractures which unite (either operative or nonoperative), the functional outcomes are the same at six months. Conclusion. With regard to the adolescent population, the existing body of evidence is insufficient to support the use of routine operative management. Regarding adult fractures, the key to identifying patients who benefit from operative management lies in the identification of risk factors for nonunion. We present an algorithm that can be used to guide both the patient and the surgeon in a joint decision-making process, in order to optimize patient satisfaction and outcomes.

Aim. The number of operatively treated clavicle fractures has increased over the past decades. Consequently, this has led to an increase in secondary procedures required to treat complications such as fracture-related infection (FRI). The primary objective of this study was to assess the clinical and functional outcome of patients treated for FRI of the clavicle. The secondary objectives were to evaluate the healthcare costs and propose a standardized protocol for the surgical management of this complication. Method. All patients with a clavicle fracture who underwent open reduction and internal fixation (ORIF) between 1 January 2015 and 1 March 2022 were retrospectively evaluated. This study included patients with an FRI who were diagnosed and treated according to the recommendations of a multidisciplinary team at the University Hospitals Leuven, Belgium. Results. We evaluated 626 patients with 630 clavicle fractures who underwent ORIF. In total, 28 patients were diagnosed with an FRI. Of these, eight (29%) underwent definitive implant removal, five (18%) underwent debridement, antimicrobial treatment and implant retention, and fourteen patients (50%) had their implant exchanged in either a single-stage procedure, a two-stage procedure or after multiple revisions. One patient (3.6%) underwent resection of the clavicle. Twelve patients (43%) underwent autologous bone grafting (tricortical iliac crest bone graft (n=6), free vascularized fibular graft (n=5), cancellous bone graft (n=1)) to reconstruct the bone defect. The median follow-up was 32.3 (P. 25. -P. 75. : 23.9–51.1) months. Two patients (7.1%) experienced a recurrence of infection. The functional outcome was satisfactory, with 26 out of 28 patients (93%) having full range of motion. The median healthcare cost was € 11.506 (P. 25. -P. 75. : € 7.953–23.798) per patient. Conclusion. FRI is a serious complication that can occur after the surgical treatment of clavicle fractures. Overall, the outcome of patients treated for FRI of the clavicle is good, when management of this complication is performed by using a multidisciplinary team approach. The median healthcare costs of these patients are up to 3.5 times higher compared to non-infected operatively treated clavicle fractures. Expert opinion considers factors such as the size of the bone defect, the condition of the soft tissue, and patient demand to guide surgical decision making

Aims. The aims of this network meta-analysis (NMA) were to examine nonunion rates and functional outcomes following various operative and nonoperative treatments for displaced mid-shaft clavicle fractures. Methods. Initial search strategy incorporated MEDLINE, PubMed, Embase, and the Cochrane Library for relevant randomized controlled trials (RCTs). Four treatment arms were created: nonoperative (NO); intramedullary nailing (IMN); reconstruction plating (RP); and compression/pre-contoured plating (CP). A Bayesian NMA was conducted to compare all treatment options for outcomes of nonunion, malunion, and function using the Disabilities of the Arm Shoulder and Hand (DASH) and Constant-Murley Shoulder Outcome scores. Results. In all, 19 RCTs consisting of 1,783 clavicle fractures were included in the NMA. All surgical options demonstrated a significantly lower odds ratio (OR) of nonunion in comparison to nonoperative management: CP versus NO (OR 0.08; 95% confidence interval (CI) 0.04 to 0.17); IMN versus NO (OR 0.07; 95% CI 0.02 to 0.19); RP versus NO (OR 0.07; 95% CI: 0.01 to 0.24). Compression plating was the only treatment to demonstrate significantly lower DASH scores relative to NO at six weeks (mean difference -10.97; 95% CI -20.69 to 1.47). Conclusion. Surgical fixation demonstrated a lower risk of nonunion compared to nonoperative management. Compression plating resulted in significantly less disability early after surgery compared to nonoperative management. These results demonstrate possible early improved functional outcomes with compression plating compared to nonoperative treatment. Surgical fixation of mid-shaft clavicle fractures with compression plating may result in quicker return to activity by rendering patients less disabled early after surgery.

Implant removal after clavicle plating is common. Low-profile dual mini-fragment plate constructs are considered safe for fixation of diaphyseal clavicle fractures. The aim of this study was to investigate: (1) the biomechanical competence of different dual plate designs from stiffness and cycles to failure, and (2) to compare them against 3.5mm single superoanterior plating. Twelve artificial clavicles were assigned to 2 groups and instrumented with titanium matrix mandible plates as follows: group 1 (G1) (2.5mm anterior+2.0mm superior) and group 2 (G2) (2.0mm anterior+2.0mm superior). An unstable clavicle shaft fracture (AO/OTA15.2C) was simulated. Specimens were cyclically tested to failure under craniocaudal cantilever bending, superimposed with torsion around the shaft axis and compared to previous published data of 6 locked superoanterior plates tested under the same conditions (G3). Displacement (mm) after 5000 cycles was highest in G3 (10.7±0.8) followed by G2 (8.5±1.0) and G1 (7.5±1.0), respectively. Both outcomes were significantly higher in G3 as compared to both G1 and G2 (p≤0.027). Cycles to failure were highest in G3 (19536±3586) followed by G1 (15834±3492) and G2 (11104±3177), being significantly higher in G3 compared to G2 (p=0.004). Failure was breakage of one or two plates at the level of the osteotomy in all specimens. One G1 specimen demonstrated failure of the anterior plate. Both plates in other G1 specimens. Majority of G2 had fractures in both plates. No screw pullout or additional clavicle fractures were observed among specimens. Low-profile 2.0/2.0 dual plates demonstrated similar initial stiffness compared to 3.5mm single plates, however, had significantly lower failure endurance. Low-profile 2.5/2.0 dual plates showed significant higher initial stiffness and similar resistance to failure compared to 3.5mm single locked plates and can be considered as a useful alternative for diaphyseal clavicle fracture fixation. These results complement the promising results of several clinical studies

Purpose: In a prospective randomized clinical trial, we have previously reported the “limb-specific” results comparing operative (plate fixation) versus non-operative (sling) treatment for completely displaced fractures of the shaft of the clavicle. We also sought to determine the effect that a fracture of the shaft of the clavicle had on general health status, as measured by the SF-36 General Health Status instrument. We then evaluated the effects of different treatment methods (operative versus non-operative), on general health scores.

Method: We performed a multi-center, randomized clinical trial of operative versus non-operative treatment of completely displaced clavicular shaft fractures in 111 patients. In addition to radiographic, surgeon-based, and limb-specific data we prospectively gathered SF-36 questionnaires at baseline, and at 6 weeks and 3, 6, 12, and 24 months post-injury.

Results: Results: Both groups had SF-36 scores equivalent to or slightly superior to population norms at baseline. A clavicular shaft fracture had a significant negative effect on SF-36 scores (especially the physical components) in both groups at 6 weeks (p< 0.01) and 3 months (p< 0.01). There was a statistically greater decrease in Physical Component Scores (PCS) in the non-operative group compared to the operative group (P< 0.05). At 6 months, scores had returned to pre-operative levels in the operative group, but remained significantly decreased in the non-operative group (p=0.04). This difference persisted at the one and two year points.

Conclusion: A displaced fracture of the clavicular shaft has a clinically significant negative effect on general health status scores. This effect can be mitigated by primary operative fixation, which restores scores to normal levels by six months post-injury. Patients treated non-operatively for a displaced fracture of the shaft of the clavicle demonstrated lower PCS scores at two years post-injury. This information is useful in counseling patients with regards to treatment options following displaced fractures of the clavicle shaft.

Abstract. Aim. The aim of this study was to present the results of treatment of displaced lateral clavicle fractures by an arthroscopically inserted tightrope device (‘Dogbone’, Arthrex). Methods. We performed a retrospective series of our patients treated with this technique between 2015 and 2019. Patients were identified using the ‘CRS Millennium’ software package and operation notes/clinic letters were analysed. We performed an Oxford Shoulder Score (OSS) on all the patients at final follow-up. Our electronic ‘PACS’ system was used to evaluate union in the post-operative radiographs. Results. We treated 26 patients with displaced lateral clavicle fractures between 2015 and 2019. There were 4 patients who were treated with a ‘dogbone’ and supplementary plate fixation and the remaining 22 were treated with a ‘dogbone’ alone. Radiological union was seen in 22 (84%) patients. The mean Oxford Shoulder Score (OSS) was 46. Apart from one patient who required removal of the superior endobutton and knot under local anaesthetic there was no other secondary surgery. There were no cases of infection, nerve injury or frozen shoulder. Conclusions. Arthroscopic ‘dogbone’ treatment of lateral clavicle fractures is a safe, cosmetically friendly technique with promising high rates of fracture union and return to normal function. We recommend its use over the more conventional treatment of a hook plate

Introduction. The Tour de France, commonly recognised and the hardest physical endurance event on the planet, is an iconic cycling competition with a history of ever impressive performances and increasingly notable injuries. This study aims to methodologically catalogue and analyse injuries sustained by professional riders over a span of six years and understand the operative workload created by this prestigious race. (2018–2023). Methods. Data was gathered from multiple publicly available sources, including pro-cycling stats, news articles, team press releases and independent medical reports. Each injury was categorized by year, rider, and injury type. Results. From 2018–2023, there was a significant diversity in both injured body part and mechanism of injury. Of the 124 recorded race ending incidents clavicle fractures accounted 19.4%, laceration/contusions 12.1%, patella fractures 10.5% and elbow fractures 7.3%. Other. notable other body areas undergoing surgical intervention were hand fractures 5.6%, pelvic fractures 2.4% and femoral fracture 1.6%. At a mean of 20.67 injuries per tour, this accounts for almost exactly one race ending injury per day where an athlete finishes the day on the operating table, rather than the team bus. Discussion. The Tour de France's rigorous challenges are mirrored in its injury statistics. Over six years, clavicle fractures were most prevalent, likely due to cyclists' instinct to brace during crashes. Lacerations, contusions, and patella fractures also featured prominently. Alarmingly, each race stage averaged an injury severe enough for surgical intervention. This data highlights the imperative need for enhanced protective measures, race regulations, and medical preparedness to protect these elite athletes
