Aims. To propose a new method for evaluating paediatric radial neck fractures and improve the accuracy of fracture angulation measurement, particularly in younger children, and thereby facilitate planning treatment in this population. Methods. Clinical data of 117 children with radial neck fractures in our hospital from August 2014 to March 2023 were collected. A total of 50 children (26 males, 24 females, mean age 7.6 years (2 to 13)) met the inclusion criteria and were analyzed. Cases were excluded for the following reasons: Judet grade I and Judet grade IVb (> 85° angulation) classification; poor radiograph image quality; incomplete clinical information; sagittal plane angulation; severe displacement of the ulna fracture; and Monteggia fractures. For each patient, standard elbow anteroposterior (AP) view radiographs and corresponding CT images were acquired. On radiographs, Angle P (complementary to the angle between the long axis of the radial head and the line perpendicular to the physis), Angle S (complementary to the angle between the long axis of the radial head and the midline through the proximal radial shaft), and Angle U (between the long axis of the radial head and the straight line from the distal tip of the capitellum to the coronoid process) were identified as candidates approximating the true coronal plane angulation of radial neck fractures. On the coronal plane of the CT scan, the angulation of radial neck fractures (CTa) was measured and served as the reference standard for measurement. Inter- and intraobserver reliabilities were assessed by Kappa statistics and intraclass correlation coefficient (ICC). Results. Angle U showed the strongest correlation with CTa (p < 0.001). In the analysis of inter- and intraobserver reliability, Kappa values were significantly higher for Angles S and U compared with Angle P. ICC values were excellent among the three groups. Conclusion. Angle U on AP view was the best substitute for CTa when evaluating radial neck fractures in children. Further studies are required to validate this method.

At-home softcast removal with no routine clinical follow-up has shown to be safe and effective following paediatric orthopaedic trauma. It minimises clinician contact time and reduces cost. However, there is limited data on the caregiver experience. Retrospective analysis of paediatric fractures requiring application of circumferential softcast that was later removed at home. Two time points were included: (1)July–September 2022, (2)February–April 2023. Demographics data included age, fracture classification, angulation, manipulation requirement, complications or unplanned re-attendance. Caregivers were given an information leaflet on cast removal. Caregivers completed a telephone Likert questionnaire reviewing time taken to remove cast, qualitative descriptors of cast removal and overall satisfaction. 77 families were contacted at mean 93 days post injury. Mean age was 7.5 years. 41(53%) were distal radius and 20(26%) both-bone forearm fractures. The remaining were hand, elbow or tibia injuries. 40(52%) injuries required manipulation under procedural sedation with mean sagittal angulation 24 degrees. 13(17%) patients re-attended with cast problems. Caregivers estimated a mean 13 minutes to remove cast. 83% found it ‘extremely’ or ‘somewhat’ easy. 75% were ‘extremely’ or ‘somewhat’ satisfied. 71% were ‘extremely’ or ‘somewhat’ likely to recommend at-home cast removal. Qualitative descriptors ranged from from ‘traumatising’ to ‘fun’ and ‘straightforward’. The experience at our tertiary centre confirms at-home softcast removal with no further orthopaedic follow-up is safe and feasible, even in those requiring manipulation under sedation. The majority of families reported a positive experience; this however is not universal. Adequate patient information resources are integral to a positive caregiver's experiences

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

The aim of the study was to assess the outcome of fractures of the fifth metacarpal neck and to develop an accurate method of assessing fracture angulation. Forty-two patients who were available for review were assessed using a patient questionnaire, assessing range of movement, cosmesis, pain and strength. A trigonometric method of determining true fracture angulation from AP and oblique radiographs was developed. There were 36 males and 6 females with an average age of 23.4 years, with a minimum follow up of 12 months. Patients with fractures angulated more than 45 degrees in whom reduction was not performed had a significantly lower score for grip strength and function. 32 patients reported a mild cosmetic deformity. The method of reduction and the method and duration of immobilisation did not correlate with the final outcome. A phantom was constructed that confirmed the accuracy of the method of calculating true fracture angulation from the oblique radiographs. Fractures of the fifth metacarpal neck if not reduced to a true angulation of less than 45 degrees produce an unsatisfactory outcome. A method of assessing true angulation has been developed

Aims

Isolated fractures of the ulnar diaphysis are uncommon, occurring at a rate of 0.02 to 0.04 per 1,000 cases. Despite their infrequency, these fractures commonly give rise to complications, such as nonunion, limited forearm pronation and supination, restricted elbow range of motion, radioulnar synostosis, and prolonged pain. Treatment options for this injury remain a topic of debate, with limited research available and no consensus on the optimal approach. Therefore, this trial aims to compare clinical, radiological, and functional outcomes of two treatment methods: open reduction and internal fixation (ORIF) versus nonoperative treatment in patients with isolated ulnar diaphyseal fractures.

Aims

There is ambiguity surrounding the degree of scaphoid union required to safely allow mobilization following scaphoid waist fracture. Premature mobilization could lead to refracture, but late mobilization may cause stiffness and delay return to normal function. This study aims to explore the risk of refracture at different stages of scaphoid waist fracture union in three common fracture patterns, using a novel finite element method.

Softcast is an attractive alternative to POP for unstable forearm fractures, providing a comfortable, water-resistant splint that can be removed without a plaster saw. Unreinforced Softcast has, however, only been recommended for buckle fractures. A laboratory study was undertaken to compare standardised POP, Softcast and reinforced Softcast splints at clinically relevant endpoints. The load at clinical failure of a 6-wrap Softcast forearm splint was 504N in bending, 202N in kinking, and 11Nm in torsion (equalling 30.4%, 26% and 42.2% of the equivalent values for a circumferential 4-wrap POP). Softcast was however stronger in all modes than a fibreglass-reinforced Softcast splint, such has been recommended for acute fractures. Furthermore, the load to failure in all modes exceeds that which can be exerted by body weight in many paediatric patients. Softcast demonstrated complete recovery of its original shape on unloading, and was 4% lighter than POP. A 6-wrap Softcast splint provides adequate mechanical stability and protection for paediatric patients up to 20kg, not engaged in high-risk activities. The primary risk is not of fracture angulation and loss of position, but temporary indentation of the splint, causing discomfort or pain. Considering its ease of removal, Softcast may be preferable for younger paediatric patients

The use of external fixation in open tibia fractures with severe soft tissue injury is the most preferred and safe treatment. The primary allograft application is doubtful due to high infection risk. The evaluation of the results of open tibia fractures type II and III according Gustillo-Anderson that were treated with simultaneous external fixation and allograft application. From 2005–2007, twenty nine open tibia shaft fractures in 27 patients (2 bilateral) with mean age of 35 years-old were treated. According Gustillo-Anderson classification, there were 20 GII, 6GIIIa and 3GIIIb open tibia shaft fractures without severe bone loss. All patients were treated with thorough and extensive surgical debridment, external fixation and simultaneous application of allograft and double antibiotic scheme. The patients were followed up initially weekly till stitches removal and every second week till the external fixation removal without developing any signs of infection. Overall, there were uncomplicated union in 23 cases (18 GII, 3GIIIa and 2GIIIb) whereas in 5 cases we had to change method of treatment (3 GII and 2GIIIa) due to union delay or non acceptable fracture angulations. There were also a case that developed deep infection and septic pseudarthrosis. The simultaneous external fixation and allograft application seems to provide a small advantage in open fracture consolidation despite the established wisdom for allograft use on a later stage. The proper initial open fracture estimation, the right surgical treatment, the surgeon’s experience and a strict patient’s follow up schedule are fundamental for a good final outcome

Introduction and Aims: Union of femoral shaft fractures in a shortened position is a recognised complication of spica cast treatment. Such shortening can only be assessed radiographically until the spica has been removed. The constraints of a spica cast complicate the imaging of the femur and may lead to error in assessing shortening. This study aims to quantify the magnitude of such error for application to clinical practice. Method: A model for a spiral femoral fracture in a spica cast was devised. Shortening of the femoral segment through telescoping and angulation was controlled with a Wagner lengthening device external to the spica. Shortening from angulation and telescoping were varied and radiographic measurements compared with real measurements. The correlation between true and radiographic shortening of > 2cm was measured with the kappa value. Results: There was good agreement between radiological and real shortening of > 2cm. Where shortening was present without angulation, the radiological measurement over-estimated the degree of shortening. The error increased with the amount of shortening. Angulation of more than 30 degrees caused the radiological measurement to under-estimate the true amount of segmental shortening. Conclusion: This study suggests that radiological measurement of femoral shortening in a spica should reliably predict clinically significant shortening when there is less than 30 degrees of fracture angulation

AIM: The purpose of this prospective study was to asses the outcome of antegrade intramedullary wiring of displaced distal end of fifth metacarpal fracture in skeletally immature. Intramedullary wiring for fracture metacarpals have been well described in the literature. Retrograde wiring for neck of metacarpal fractures have been associated with limitation of extension at metacarpo-phalangeal joint due to involvement of gliding extensor mechanism. Foucher described ‘Bouguet’ osteosynthesis with multiple wires for metacarpal neck fracture which can be technically demanding in small bones of children. We describe an antegrade wiring using a single bent K-wire at the tip for reducing and stabilising displaced metacarpal neck fracture by rotating 180 degree after crossing fracture site, a method similar to Methaizeau technique for stabilisation of displaced radial neck fractures using nancy nail. METHOD: Between 2000 to 2006 we treated 9 boys with displaced distal end of fifth metacarpal fracture +/− rotational deformity of little finger using above technique. All of them had closed injuries and the indication for surgery was rotatory mal-alignment or fracture angulation more than 40 degrees. The assessment involved a clinical and radiological examination. The mean age was 13 years. The mean follow-up was 15 months. RESULTS: All fractures healed in anatomical alignment. There was no loss of active or passive movement of the little finger metacarpo-phalangeal joint or weakness of grip strength in any children. All children returned to pre-injury activity level within 4–6 weeks. There were no complications. CONCLUSION: Early results of treating displaced little finger metacarpal neck fracture in children using antegrade intramedullary wire are encouraging

We undertook a prospective, single blinded, randomized, controlled trial of one hundred children treated with either an above or below elbow cast for treatment of closed, distal third forearm fractures requiring reduction. The re-manipulation rate in the below elbow group was 2% (95%CI: 0–11%) compared to 6% (95%CI: 2–15%) in the above elbow group, p=0.62. Above elbow casts do not appear to improve fracture immobilization nor reduce the requirement for re-manipulation in pediatric distal third forearm fractures. Debate exists regarding the benefits of using below elbow casts instead of above elbow casts for maintaining reduction in pediatric distal third forearm fractures. The literature indicates a loss of reduction rate of 14.6% of children treated in an above elbow cast and 2.5% in those treated with a below elbow cast. We undertook a prospective, single blinded, randomized, controlled trial of one hundred children treated with either an above or below elbow cast for treatment of closed, distal third forearm fractures requiring reduction. Outcome measures included re-manipulation rate, fracture displacement during cast wear, and cast complications. One hundred patients were suitably enrolled; fifty-four received an above elbow cast, forty-six received a below elbow cast. The two groups were similar in terms of age and gender. The above elbow group contained a higher proportion of both bone fractures (41/54) than the below elbow group (27/46). There were no significant differences between the two cast groups in initial, post-reduction or cast-off fracture angulation; nor any difference in the amount of fracture displacement during cast wear. The number of cast complications was similar between the two groups. The re-manipulation rate in the below elbow group was 2% (95%CI: 0–11%) compared to 6% (95%CI: 2–15%) in the above elbow group, p=0.62. Above elbow casts do not appear to improve fracture immobilization nor reduce the requirement for re-manipulation in pediatric distal third forearm fractures. Funding Hip Hip Hooray, Saskatoon

The aim of this study was to define the complications and long-term outcome following adolescent mid-shaft clavicular fracture.

Objectives

This review aims to summarize the outcomes used to describe effectiveness of treatments for paediatric wrist fractures within existing literature.

Introduction. Surgical treatment is justified in patients with fifth metacarpal shaft fractures with angulation exceeding 30 degrees, as these patients are prone to have shortening, restriction of movements, decreased efficiency of the flexor tendons and poor cosmetic results1,2. The authors describe a new technique where these patients can be treated in the clinic non-surgically. Material and Methods. Twenty-three patients with angulated fractures were prospectively enrolled for the study from Jan 2009 to Dec 2009. After appropriately instructing the patient, an ulnar nerve block was performed at the wrist. Once the nerve block had taken effect, the fracture was manipulated and an ulna gutter 3-point moulded splint was applied in the plaster room. The reduction was then confirmed with an x-ray. The patients were seen at 3 weeks for splint removal and for long-term follow-up at least 6 months later. Results. All the patients had a completely pain-free manipulation and complete reduction was achieved in all the patients. There were no complications related to the technique. Conclusions. In the NHS with pressure on resources, the authors suggest the treatment described above of these fractures in the clinic. It is a safe, cost-effective and easily learnt technique

Rates of operative fixation for clavicle fractures have been increasing over recent years, but non-operative treatment remains the most common treatment. However, the reported results of case series of non-operatively and operatively treated clavicle fractures show considerable variation, making comparison difficult. Non-operative treatment leads to unsatisfactory results in approximately 3 – 10% of cases, sometimes requiring delayed surgical intervention. Recent studies exploring predictors of poor results after non-operative treatment have shown that fracture displacement is a significant predictor of poor outcome. However, fracture comminution, angulation, shortening, smoking, age, and fracture type and location are not consistently associated with worse outcomes. This has lead to increased interest in surgical fixation for displaced fractures. Prior to the large randomised trial by the Canadian Orthopaedic Trauma Society (COTS), controlled trials comparing surgery to non-operative treatment provided no significant support for surgical fixation. The COTS study provides some evidence for plating displaced mid-shaft fractures, however, partly due to methodological issues, recent reviews of the topic have concluded that additional, more rigorous studies are required to confirm the findings of the COTS trial. Intramedullary fixation is also popular, but it does not have the weight of evidence of plate fixation

Purpose of the study: Lengthening can be proposed for children with congenital or acquired short fingers in order to overcome the length defect and improve function, the aesthetic aspect, or enable installation of a hand prosthesis. Three techniques have been proposed. The purpose of this study was to compare the three techniques in terms of lengthening, achieved, cure index, and complication rate. Material and method: The was a series of 13 lengthening procedures for metacarpals in children with congenital or post-trauma sequelae. Results: The callotasis method was used for seven children. Slow distraction using a mini-external fixator was applied for progressive lengthening without bone graft. Mean lengthening was 13 mm (range 8–21) for mean a mean cure index of 81 d/cm (range 41.7 to 140.9). There was one major complication: fracture with angulation. The two-phase progressive distraction method with graft was used in four children. The distraction using a mini-external fixator was rapid, followed by second phase bone graft. Mean lengthening was 22 mm (range 13–32) with a cur index of 40.8 d/cm (range 32.8 to 46). There was one fracture of a grafted zone. Single-phase extemporaneous lengthening with immediate graft was used for two children. The intraoperative distraction of the osteotomy was followed immediately by insertion of the graft. Mean lengthening was 9 mm for a cure index of 50 d/cm. One patient required tenolysis of the extensor at six months because of adherences at the graft site. Discussion: Our results suggest that the two- phase distraction-graft method enables greater lengthening than the callatasis technique for shorter treatment periods but a the cost of a second operation and donor site morbidity. The extemporaneous lengthening method is less ambitious, achieving lengthening to the order of 10 mm, but with a less aggressive procedure

Between 1996 and 2003 six institutions in the United States and France contributed a consecutive series of 234 fractures of the femur in 229 children which were treated by titanium elastic nailing. Minor or major complications occurred in 80 fractures. Full information was available concerning 230 fractures, of which the outcome was excellent in 150 (65%), satisfactory in 57 (25%), and poor in 23 (10%). Poor outcomes were due to leg-length discrepancy in five fractures, unacceptable angulation in 17, and failure of fixation in one. There was a statistically significant relationship (p = 0.003) between age and outcome, and the odds ratio for poor outcome was 3.86 for children aged 11 years and older compared with those below this age. The difference between the weight of children with a poor outcome and those with an excellent or satisfactory outcome was statistically significant (54 kg vs 39 kg; p = 0.003). A poor outcome was five times more likely in children who weighed more than 49 kg

Passive and active elbow flexion was performed in eight cadaveric arms to determine the effect of Type 1 coronoid fractures and suture repair on kinematics. Testing was performed in ligamentously intact and MCL deficient elbows; with radial head arthroplasty (RHA); with an intact coronoid, following a Type 1 fracture, and with suture repair of the coronoid. There was an alteration in elbow kinematics and stability following Type 1 coronoid fractures that was not corrected with coronoid repair. Suture fixation of the coronoid is probably unnecessary if the lateral ligaments are repaired and the radial head is repaired or replaced. To determine the effect of fixation of Type 1 coronoid fractures on elbow stability and kinematics in ligamentously intact and medial collateral ligament (MCL) deficient elbows with radial head arthroplasty (RHA). Type 1 coronoid fractures cause changes in elbow kinematics and stability that are not corrected with suture repair. Suture fixation of Type 1 coronoid fractures is probably unnecessary if the lateral ligaments are repaired and the radial head is repaired or replaced. With intact ligaments, there was an increase in valgus angulation following a Type 1 coronoid fracture (p< 0.05) that was not corrected with fixation. With MCL deficiency, there was no change in valgus angulation for all coronoid states. For both ligament states, there was an increase maximum varus-valgus laxity after a Type 1 coronoid fracture with forearm pronation (p=0.03) that was not corrected with fixation (p=0.4). Kinematic data was collected from eight cadaveric arms during passive and simulated active elbow motion. The protocol was performed in stable and MCL deficient elbows with RHA. Testing occurred with the coronoid intact, following Type 1 coronoid fracture, and with suture repair of the fracture. Valgus angulation and maximum varus-valgus laxity were measured. With intact ligaments, Type 1 coronoid fractures cause an alteration in elbow kinematics and laxity that is not corrected with suture fixation. With MCL disruption, Type 1 coronoid fractures have no effect on elbow kinematics and a small effect on laxity that is not corrected with coronoid repair.
