Aims. The aim of this study was to explore clinicians’ experience of a paediatric randomized controlled trial (RCT) comparing surgical reduction with non-surgical casting for displaced distal radius fractures. Methods. Overall, 22 staff from 15 hospitals who participated in the RCT took part in an interview. Interviews were informed by phenomenology and analyzed using thematic analysis. Results. Analysis of the findings identified the overarching theme of “overcoming obstacles”, which described the challenge of alleviating staff concerns about the use of non-surgical casting and recruiting families where there was treatment uncertainty. In order to embed and recruit to the Children’s Radius Acute Fracture Fixation Trial (CRAFFT), staff needed to fit the study within clinical practice, work together, negotiate treatment decisions, and support families. Conclusion. Recruiting families to this RCT was challenging because staff were uncertain about longer-term patient outcomes, and the difficulties were exacerbated by interdisciplinary tensions. Strong family and clinician beliefs, coupled with the complex nature of emergency departments and patient pathways that differed site-by-site, served as barriers to recruitment. Cementing a strong research culture, and exploring families’ treatment preferences, helped to overcome recruitment obstacles. Cite this article: Bone Jt Open 2024;5(4):324–334

Aims

The aim of this trial was to assess the cost-effectiveness of a soft bandage and immediate discharge, compared with rigid immobilization, in children aged four to 15 years with a torus fracture of the distal radius.

This study was conducted to investigate the characteristics, complications, radiologic features and clinical course of patients undergoing reduction of forearm fractures in order to better inform patient prognosis and postoperative management. We conducted a retrospective cohort study of 1079 pediatric patients treated for forearm fractures between January 2014 and September 2021 in a 327 bed regional medical center. A preoperative radiological assessment and chart review was performed. Percent fracture displacement, location, orientation, comonution, fracture line visibility and angle of angulation were determined by AP and lateral radiographs. Percent fracture displacement was derived by: (Displacement of Bone Shafts / Diameter) x 100% = %Fracture Displacement. Angle of angulation and percent fracture displacement were calculated by averaging AP and lateral radiograph measurements. 80 cases, averaging 13.5±8.3 years, were identified as having a complete fracture of the radius and/or ulna with 69 receiving closed reduction and 11 receiving fixation via an intramedullary device or percutaneous pinning. Eight patients (10%) experienced complications with four resulting in a refracture and four resulting in significant loss of reduction (LOR) without refracture. Fractures in the proximal ⅔s of the radius were associated with a significant increase in complications compared to fractures in the distal ⅓ of the radius (31.6% vs 3.4%) (P=.000428). Likewise, a higher percent fracture displacement was associated with a decreased risk of complications (28.7% vs 5.9% displacement)(P=0.0403). No elevated risk of complications was found based on fracture orientation, angulation, fracture line visibility, forearm bone(s) fractured, sex, age or arm affected. Our result highlights radius fracture location and percent fracture displacement as markers with prognostic value following forearm fracture. These measurements are simply calculated via pre-reduction radiographs, providing an efficient method of informing risk of complications following forearm fracture

Timely and competent treatment of paediatric fractures is paramount to a healthy future working population. Anecdotal evidence suggests that children travel greater distances to obtain care compared to adults causing economic and geographic inequities. This study aims to qualify the informal regionalization of children's fracture care in Ontario. The results could inform future policy on resource distribution and planning of the provincial health care system. A retrospective cohort study was conducted examining two of the most common paediatric orthopaedic traumatic injuries, femoral shaft and supracondylar humerus fractures (SCH), in parallel over the last 10 years (2010-2020) using multiple linked administrative databases housed at the Institute for Clinical Evaluative Sciences (ICES) in Toronto, Ontario. We compared the distance travelled by these pediatric cohorts to clinically equivalent adult fracture patterns (distal radius fracture (DR) and femoral shaft fracture). Patient cohorts were identified based on treatment codes and distances were calculated from a centroid of patient home forward sortation area to hospital location. Demographics, hospital type, and closest hospital to patient were also recorded. For common upper extremity fracture care, 84% of children underwent surgery at specialized centers which required significant travel (44km). Conversely, 67% of adults were treated locally, travelling a mean of 23km. Similarly, two-thirds of adult femoral shaft fractures were treated locally (mean travel distance of 30km) while most children (84%) with femoral shaft fractures travelled an average of 63km to specialized centers. Children who live in rural areas travel on average 51km more than their adult rural-residing counterparts for all fracture care. Four institutions provide over 75% of the fracture care for children, whereas 22 institutions distribute the same case volume in adults.?. Adult fracture care naturally self-organizes with proportionate distribution without policy-directed systemization. There is an unplanned concentration of pediatric fracture care to specialized centers in Ontario placing undue burden on pediatric patients and inadvertently stresses the surgical resources in a small handful of hospitals. In contrast, adult fracture care naturally self-organizes with proportionate distribution without policy-directed systemization. Patient care equity and appropriate resource allocation cannot be achieved without appropriate systemization of pediatric fracture care

Purpose of study:. The treatment goals in diaphyseal radius fractures are to regain and maintain length and rotational stability. Open reduction and plating remains the gold standard but carries the inherent problems of soft tissue disruption and periosteal stripping. Intramedullary nailing offers advantages of minimally invasive surgery and minimal soft tissue trauma. The purpose of this study is to describe the results of locked intramedullary nailing for adult gunshot diaphyseal radius fractures. Methods:. A retrospective review of clinical and radiological records was performed on patients with intramedullary nailing of isolated gunshot radius fractures between 2009 and 2013. Results:. Twenty-two nails were inserted in 22 patients, all males with a mean age of 28.9 years (range 19–40). Follow-up was for an average period of 11 weeks (range 6–24). One patient had a median nerve palsy and 2 a posterior interosseous nerve palsy pre-operatively. All operations were performed within 3 to 12 days of the injury. No primary bone grafting was performed. All fractures united with the index procedure. Average time to union was 10 weeks (range 8–24). Fourteen patients (64%) had their radial bow restored and maintained; these patients had minimal comminution in the middle to distal third of the radius. The bow could not be satisfactorily restored in severely comminuted fractures in the proximal third of the radius. Using the Anderson classification outcome was excellent in 14 patients (64%), satisfactory in 6 (27%) and unsatisfactory in 2 (9%). There were no complications associated with the surgery and one patient required nail removal for implant migration. Conclusion:. Intramedullary nail fixation of gunshot radius fractures has shown promising results in our hands with no significant complications. The fracture site and zone of comminution directly influenced our ability to restore radial bow

Guidelines for the use of preoperative blood tests for elective surgery were established. However, there is less evidence and no guidelines regarding using these tests when a young, healthy patient undergoes minor orthopaedic trauma surgery. Bloodwork is often ordered routinely, regardless of medical history or the nature of the injury. We hypothesized that unnecessary blood work is requested for younger pre-operative patients, and their results will not change peri-operative management. This practice is not a judicious use of healthcare resources. This study aimed to evaluate the frequency, type, cost, and impact on clinical decisions if standard preoperative bloodwork was completed in healthy patients requiring surgical management of a minor fracture or dislocation. After the approval of our institutional ethics board, a retrospective chart review was conducted. Inclusion criteria were patients aged 18-60 years, who had an isolated minor orthopaedic trauma requiring outpatient surgery, who were American Society of Anesthesiologists (ASA) class 1. ASA class 1 is defined as “a normal healthy patient, without any clinically important comorbidity and without a clinically significant past/present medical history.” Data records from January 1, 2016, to December 31, 2018, were extracted from a provincial database (the Analytics Data Integration, Measurement and Reporting) for five hospitals. Data including demographics, surgical treatment, type and number of blood tests ordered, and ordering physician were collected. Any abnormal test results were checked to see whether they led to a change in patient management or related to a postoperative adverse event. Independent samples t-tests and Chi-square tests were used to compare the characteristics of patients who had preoperative bloodwork versus those who did not. The cost of preoperative blood work was estimated. During these two years, 627 patients met inclusion criteria, and 27% (n=168) of these patients had bloodwork completed pre-operatively, while only 34% (n=57) of these had one or more abnormal laboratory parameters. These abnormalities were minor and did not alter clinical management or result in repeated bloodwork peri-operatively. Patients who had bloodwork were significantly older (40.2 years) compared with patients without preoperative blood work (37.8 years; p=0.03), but there was no difference in sex between those who had bloodwork (53.4% male) and those who did not (51.4% male; p=0.63). The most common blood test ordered was a complete blood count, and the most commonly abnormal result was a mildly elevated white blood cell count (19%; n= 29). The most common patients to receive bloodwork were those with ankle (34%) and distal radius (34%) fractures. The bloodwork was primarily ordered by clinical associates (26%; n=46) and emergency department physicians (22%; n=38). Without considering lab personnel, consumables, and analysis time, the cost of this bloodwork was approximately $7685, an average of $45 per patient. Pre-operative bloodwork in young, healthy, asymptomatic patients requiring outpatient surgery for minor orthopaedic trauma had no clinical significance and did not change patient management. Rigorous prospective research is warranted to establish national guidelines for appropriate pre-operative bloodwork ordering to minimize unnecessary and costly investigations

A common location for radius fracture is the proximal radial head. With the arm in neutral position, the fracture usually happens in the anterolateral quadrant (Lacheta et al., 2019). If traditional surgeries are not enough to induce bone stabilization and vascularization, or the fracture can be defined grade III or grade IV (Mason classification), a radial head prosthesis can be the optimal compromise between bone saving and recovering the “terrible triad”. A commercially available design of radial head prosthesis such as Antea (Adler Ortho, Milan, Italy) is characterized by flexibility in selecting the best matching size for patients and induced osteointegration thanks to the Ti-Por. ®. radial stem realized by 3D printing with laser technique (Figure 1). As demonstrated, Ti-Por. ®. push-out resistance increased 45% between 8 −12 weeks after implantation, hence confirming the ideal bone-osteointegration. Additional features of Antea are: bipolarity, modularity, TiN coating, radiolucency, hypoallergenic, 10° self-aligning. The osteointegration is of paramount importance for radius, in fact the literature is unfortunately reporting several clinical cases for which the fracture of the prosthesis happened after bone-resorption. Even if related to an uncommon activity, the combination of mechanical resistance provided by the prosthesis and the stabilization due to the osteointegration should cover also accidental movements. Based upon Lacheta et al. (2019), after axial compression-load until radii failure, all native specimens survived a compression-load of 500N, while the failure happened for a mean compression force of 2560N. The aim of this research study was to test the mechanical resistance of a radial head prosthesis obtained by 3D printing. In detail, a finite element analysis (FEA) was used to understand the mechanical resistance of the core of the prosthesis and the potential bone fracture induced in the radius with simulated bone- resorption (Figure 2a). The critical level was estimated at the height for which the thickness of the core is the minimum (Figure 2b). Considered boundary conditions:. - Full-length prosthesis plus radius out of the cement block equal to 60mm (Figure 2a);. - Bone inside the cement equal to 60mm (Figure 2b);. - Load inclined 10° epiphysiary component (Figure 2c);. - Radius with physiological or osteoporotic bone conditions;. - Load (concentrated in the sphere simulating full transmission from the articulation) of 500N or 1300N or 2560N. Figure 3 shows the results in terms of maximum stress on the core of the prosthesis and the risk of fracture (Schileo et al., 2008). According to the obtained results, the radial head prosthesis shows promising mechanical resistance despite of the simulated bone-resorption for all applied loads except for 2560N. The estimated mechanical limit for the material in use is 200MPa. The risk of fracture is in agreement with the experimental findings (Lacheta et al. (2019)), in fact bone starts to fail for the minimum reported failure load, but only for osteoporotic conditions. The presented FEA aimed at investigating the behavior of a femoral head prostheses made by 3D printing with simulated bone-resorption. The prosthesis shows to be a skilled solution even during accidental loads. For any figures or tables, please contact the authors directly

Aims. Describe a statistical and economic analysis plan for the Distal Radius Acute Fracture Fixation Trial 2 (DRAFFT2) randomized controlled trial. Methods. DRAFFT2 is a multicentre, parallel, two-arm randomized controlled trial. It compares surgical fixation with K-wires versus plaster cast in adult patients who have sustained a dorsally displaced fracture of the distal radius. The primary outcome measure is the Patient-Rated Wrist Evaluation (PRWE, a validated assessment of wrist function and pain) at 12 months post-randomization. Secondary outcomes are measured at three, six, and 12 months after randomization and include the PWRE, EuroQoL EQ-5D-5L index and EQ-VAS (visual analogue scale), complication rate, and cost-effectiveness of the treatment. Results. This paper describes the full details of the planned methods of analysis and descriptive statistics. The DRAFFT2 study protocol has been published previously. Conclusion. The planned analysis strategy described records our intent to conduct statistical and within-trial cost-utility analyses. Cite this article: Bone Joint Open 2020;1-6:245–252

Aims

Wrist arthroscopy is a standard procedure in hand surgery for diagnosis and treatment of wrist injuries. Even though not generally recommended for similar procedures, general administration of perioperative antibiotic prophylaxis (PAP) is still widely used in wrist arthroscopy.

Aims

The aim of this study was to report a complete overview of both incidence, fracture distribution, mode of injury, and patient baseline demographics of paediatric distal forearm fractures to identify age of risk and types of activities leading to injury.

Aims:. 1) To determine the predictive value of a simple stability test in children’s wrist fractures treated with simple manipulation and plaster of Paris (PoP) cast immobilisation. 2) To determine the effect of cast quality as reflected in the skin cast distance (distance between the cast and the skin in the plane of major displacement or angulation) and the cast index (the inside diameter of the cast in the sagittal plane divided by the inside diameter in the coronal plane) on re-displacement rates in children’s wrist fractures treated with simple manipulation and plaster of Paris (PoP) cast immobilisation. Methods: This is a prospective study of 57 children aged 4 to 15 with metaphyseal and Salter-Harris II wrist fractures treated with simple manipulation. Under fluoroscopic imaging, a simple stability test involving moving the hand at the wrist in the dorsopalmar, and radioulnar planes was performed following reduction, and x-ray images were saved. We recorded and compared the displacement and angulation on the initial x-rays, during the test, and at one-and 6-week follow-up. We also recorded the skin-cast distance (SCD), and the cast index (CI). Results: 38 patients had isolated radius fractures and 19 had radius and ulna fractures. Four patients needed remanipulation with K-wire fixation. Multiple regression analysis revealed significant correlation between percentage loss of reduction on testing and subsequent re-displacement (relationship between the two sets of values r = 0.6167, (p< 0.001)). This indicates that instability on testing (seen as a significant percentage loss of reduction) is likely to be associated with some loss of reduction on follow-up. There was a significant relationship between the skin cast distance and the cast index, and loss of reduction on one week follow-up. (p=0.006). Isolated radius fractures had a higher risk of re-displacement than radius and ulna fractures (3.9% and 0.9% respectively; p< 0.05%). Conclusion: Stable reduction on stability testing in wrist fractures in children immobilised in a good cast (reflected in a low SCD, and CI) is associated with a good outcome. Isolated radius and ulna fractures are more likely to re-displace than radius and ulna fractures. There is a relationship between instability and loss of position at the 1-week follow-up. Potentially unstable fractures can be prevented from slipping by a good cast. A stable fracture on our stability test rarely slips. We therefore feel that stability test is a useful adjunct in decision-making

Aims

Post-traumatic periprosthetic acetabular fractures are rare but serious. Few studies carried out on small cohorts have reported them in the literature. The aim of this work is to describe the specific characteristics of post-traumatic periprosthetic acetabular fractures, and the outcome of their surgical treatment in terms of function and complications.

Aims

The aim of this study was to explore parents’ experience of their child’s recovery, and their thoughts about their decision to enrol their child in a randomized controlled trial (RCT) of surgery versus non-surgical casting for a displaced distal radius fracture.

Aims

The distal radius is a major site of osteoporotic bone loss resulting in a high risk of fragility fracture. This study evaluated the capability of a cortical index (CI) at the distal radius to predict the local bone mineral density (BMD).

The radius has a sagittal and coronal bow. Fractures are often treated with volar anterior plating. However, the sagittal bow is often overlooked when plating. This study looks at radial morphology and the effect of plating the proximal radius, with straight plates then contoured plates bowed in the sagittal plane. We report our findings and their effect on forearm rotation. Morphology was investigated using fourteen radii. Attention was made to the proximal shaft of the radius and its sagittal bow, from this 6, 7 and 8 hole plates were contoured to fit this bow. A simple transverse fracture was then made at the apex of this bow. Supination and pronation was then compared when plating with a straight plate and a contoured plate. Ten cadavers had the ulna plating at the same level. The effect on rotation of fractures plated in the distal third shaft was also measured. A significant reduction in rotation was found, when a proximal radius fracture was plated with straight plate compared to a contoured plate: 10.8, 12.8, 21.7 degrees (p<0.05 for 6, 7, 8 hole plates). Forearm rotation was decreased further when a longer plate was used. Ulna or distal shaft plating did not reduce rotation. This study has shown a significant sagittal bow of the proximal shaft of the radius. Plating this with contoured plates in the sagittal plane improves rotation when compared to straight plates. Additional ulna plating is not a source of reduced forearm rotation

Purpose. Distal metaphyseal radial fractures are common in the paediatric population and the management of these fractures is controversial. The incidence of re-displacement in the closed management of these fractures is as much as 30% in some studies. Various methods have been described with the view to predict fracture displacement of distal radial fractures in children. One of these indices is the three point index (TPI). This index seeks to assess the adequacy of 3 point moulding and thus predict fracture displacement. It is a calculated ratio that if above 0.8 states that there is an increased risk of fracture re-displacement. The purpose of this study is to assess the accuracy of this index in predicting displacement of distal radial fractures in children. Methods. This retrospective study included 65 patients of both sexes under the age of 13 for a period of one year from January 2011 to January 2012. All patients with a dorsally displaced fracture of the distal radius were included. 22 patients were excluded because of loss to follow-up or absence of a complete series of x-rays. All patients were taken to theatre for a general anaesthetic and manipulation of their fractures using an image intensifier to confirm reduction. X-rays of initial fracture displacement, post manipulation position and follow-up fracture position at 2 and 6 weeks were assessed. The sensitivity, specificity, negative and positive predictive values of the TPI in screening for fracture re-displacement were calculated. Results. Of the 43 patients included in the study, 93% of patients had an anatomical reduction in theatre with an average TPI of 1. Nineteen patients suffered significant displacement from 2 to 6 weeks postoperatively. We found that the TPI in our study had a sensitivity of 84%, a specificity of 37%, a negative predictive value of 75% and a positive predictive value of 51%. Conclusion. We found the TPI to be a useful screening tool of later displacement for the closed management of distal metaphyseal radius fractures. NO DISCLOSURES

Purpose. To elucidate whether there is an advantage in external fixation supplementation of K-wires in comparison to K-wires and plaster, in the treatment of distal radius fractures without metaphyseal comminution. Indications. Distal intraarticular radius fractures, Frykman VIII or VIII without metaphyseal comminution. Contraindications. Metaphyseal comminution, general medical contraindications for surgical intervention. Study design. Fifty-one patients were prospectively randomised in two groups: 24 patients were treated with K-wire and spanning external fixation supplementation, and 27 were treated with K-wires and plaster. Results. Patients were monitored following the operation with a minimum follow up of 1 year, and checked independently of surgeon for pain, satisfaction and range of motion. There was a statistically significant difference in favour of the external fixation patient group for pain (Visual Analogue Score, Ex-Fix group: mean 14.9, plaster group: mean 28.1, p<0.001) and satisfaction (Ex-Fix group: mean 89.7, plaster group: mean 76.3, p<0.001,). Although one would expect that range of motion would be reduced in the external fixation group, there were no statistically significant differences found in favour of plaster; on the contrary supination results were surprisingly in favour of the external fixation group (Ex-Fix group: mean 54.4, plaster group: mean 45.2, p<0.05). Conclusion. In this study, external fixation supplementation of K-wiring had statistically significant superior results in patient satisfaction score, pain score, and wrist supination in comparison to plaster augmentation of K-wiring

There are results of our first experience treatment 8 patients who underwent endoprosthetic reconstruction of distal radius after excision of malignant tumors. All patients were treated in Sytenko Institute from 2004 to 2008 and had about 5 years follow-up. There are 3 males and 5 females and the median age at diagnosis was 36 (17–55) years. The resection length measured a mean of 8cm and was measure by radiographs, CT and MRI. Each case was malignant Giant cell tumor. There were 5 cases of primary tumor and 3 cases of local tumor relapse. The patients have had chemotherapy, tumor excision and individual custommade endoprosthetic reconstruction. Unfortunately all patients had one-two surgeries before treatment in our Clinic. We used author’s individual custommade endoprosthetsis which was performed from titanium and ceramic spraying. CT-measurement scale was used for preoperative planning and manufacture this distal radius prosthesis. One patient has had deep soft tissue infection and we were needed to remove prosthesis. One more patient had proximal radius fracture 4 month after surgery and we performed bone plate osteosynthesis. All patients (except one infection case) have satisfactory wrist range of motion and functional result of upper limb from 10 month to 5 years follow-up. It is proved that surgical procedure of the tumors of distal radius is a useful and main method of the treatment above-stated localization. The individual custommade prosthesis have a good perspectives for upper limb salvage surgery and reconstruction this area, allowing to receive good oncological and functional results

Aims. To evaluate the results of Elastic Stable Intramedullary Nailing (ESIN) for displaced, unstable paediatric forearm diaphyseal fractures. Method. A retrospective, consecutive series study of 60 patients treated with ESIN between February 1996 and July 2005. Results. There were 43 (72%) boys and 17 (28%) girls with median age of 11.5 years (range: 2.6-15.9). 54 (90%) patients had a closed injury and 6 (10%) sustained a Grade I open injury. Seven patients had an isolated radius fracture. 49 (82%) fractures were stabilised with both bone ESIN, 10 (16%) with radial and one with isolated ulnar ESIN by standard technique under tourniquet control. All but two patients were protected with an above elbow cast. Thirty-six cases (60%) were primary procedures and 24 (40%) were performed due to re-displacement following a MUA. 36 patients (60%) required a minimal open reduction. Average hospital stay was 1.8 days (1-8 days). Average length of immobilisation was 5.4 weeks (3-9 weeks). Average time for clinical fracture union was 5.7 weeks (3-13 weeks). ESIN were removed after mean period of 33.8 weeks (approx: 7.9 months). One patient had a forearm compartment syndrome and required formal fasciotomy. One patient had ulnar delayed union and one had ulnar non-union. Five patients had transient superficial radial nerve neuropraxia. Ten had soft tissue irritation leading to early nail removal in two patients and two had superficial wound infection. Three patients sustained a re-fracture with the nail in situ following a new injury. 53 (88%) patients had full elbow and wrist movements on discharge. Seven patients had restriction of forearm rotations of less than 15°. Conclusion. Good clinical outcome, transitory and modest complications; quick and safe nail removal; and better cosmesis compared to plating makes ESIN an attractive treatment option for displaced, unstable paediatric forearm diaphyseal fractures
