Clinical Problem: fractures under tension are common injuries and occur when patients are falling on partial flexed limbs under maximal contraction of the extensor muscles. Typical injuries are patella and olecranon. For these fractures the tension belt osteosyntheses is the mainly used procedure. A high complication rate regarding dislocation, bone healing, pain and functional outcome are reported. This is due to the unstable fixation with the tension belt because of the tendon insertion around the bone fragment witch allow secondary loosening of the tension belt under alternating load. This was found allready 1987 by Brill and Hopf in an experimental study. Materials and Methods: To improve stabilisation a new device was developed: the XS (4,5mm diameter) and the XXS nail (3,5mm) witch is locked with threaded wires and a set screw allows fracture compression inside the nail independend from the soft tissues around. Fiber Wire cerclage transversal around the threaded wire ends allow the fixation of additional frontal plane fragments or marginal fragments. Experimental test were performed in a patella sow-bone models and showed superior to tension bel (patella) and Plate fixation/fibula). On the other side the locked nail system allows percutaaneous osteosynthesis of the whole ulna also in shaft, distal fractures and shortening osteotomies. All clinical cases treated with the XS/XXS nail where recorded prospectively and re-examined after 6–12 months. From may 2000 to march 2002 76 patients with olecranon fractures were evaluated. 85% of the olecranon fracture patients could be re-examined. Most patients where treated immediately or after wound healing without splint. Results: the experimental results shows in all XS nail group no gap after alternating load of 250 and 500N and a rigidity a little higher than that of the not osteotomised patellae. In the tension belt groups in all tested patellae visible gaps of 1 to 3 mm occurred. There was no difference between the single and double XS nail Osteosynthesis. 71.7% of all patients with olecranon fractures showed a very good result according to the Murphy score. In 2 part fractures the rate was even 94.7%. Only in the group of more part fractures in 5.9% fair results were found. No patient showed a poor result. The technical possibilities of XS nail osteosynthesis in ulna shaft, distal fractures and shortening osteotomies are presented. Conclusions: the XS nail is a new device witch allows good anatomical reconstruction and stable fixation with immediate functional therapy in all olecranon and ulna fractures

Introduction. This study aims to investigate the relationship between ulnar fixation and postoperative satisfaction among patients with distal radius fractures accompanied by ulna styloid fractures, with a particular focus on how sociodemographic factors influence outcomes. Method. A retrospective cohort study was conducted involving 120 patients aged 26-53 who underwent surgical treatment for distal radius fractures with concomitant ulna styloid fractures between January 2018 and December 2022. Patients were divided into two groups based on whether ulnar fixation was performed. Sociodemographic data, including age, gender, socioeconomic status, education level, and occupation, were collected. All patients underwent similar physical therapy protocols in the postoperative period, and no complications were observed in any patient. Postoperative satisfaction was assessed using the Patient-Rated Wrist Evaluation (PRWE) and the Disabilities of the Arm, Shoulder, and Hand (DASH) scores at 6 and 12 months post-surgery. Statistical analysis was conducted to evaluate the influence of ulnar fixation and sociodemographic factors on patient satisfaction. Result. Patients who underwent ulnar fixation (n=60) reported significantly higher satisfaction levels compared to those who did not (n=60), as evidenced by lower PRWE and DASH scores (p < 0.05). Age, gender, and socioeconomic status were significant predictors of postoperative satisfaction. Younger patients, females, and those with higher socioeconomic status exhibited greater improvements in functional outcomes and satisfaction. However, education level and occupation did not significantly influence satisfaction scores. Conclusion. Ulnar fixation in the surgical treatment of distal radius fractures accompanied by ulna styloid fractures is associated with improved postoperative satisfaction. Sociodemographic factors, particularly age, gender, and socioeconomic status, play a crucial role in patient-reported outcomes. Tailoring postoperative care to address these sociodemographic differences may enhance overall patient satisfaction and recovery

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.

Purpose: Surgical trainees develop psychomotor skills using various techniques, with simulators providing safe practicing environments. There has been no development of virtual simulators with haptics (force feedback) that allow residents to practice the open surgical fixation of common orthopedic fractures. The main purpose of this study was to assess if residents performed similarly on a newly developed virtual simulator as on a Sawbones simulator using a modified checklist and global rating scale. Secondary purposes were to assess the reliability and validity of these procedural measurement tools.

Method: A stratified randomized within-subjects study was performed with 22 surgical trainee volunteers. They were randomized to first perform surgical fixation of the ulna using either the virtual or Sawbones simulator, and then performed the same procedure on the other simulator. Evaluators completed a task-specific checklist, global rating scale (GRS), total error score and time to completion for each participant on both simulators.

Results: The participants achieved significantly better scores on the virtual simulator compared to the Sawbones simulator (p0.8), except in time to completion. When combined, the checklist and GRS maintained high levels of internal consistency (Cronbach’s a > 0.80) and inter-rater reliability (intraclass coefficient > 0.90) for both simulators. A Pearson’s product moment correlation was used to demonstrate criterion validity of the measurement tools. They were all significantly correlated to each other within simulators (p0.9), while the virtual simulator achieved construct validity for the GRS and total error score (p1.1).

Conclusion: The modified procedural measurement tools demonstrate reliability and validity and the virtual simulator shows evidence of construct validity. These tools were used to evaluate participants, demonstrating the achievement of better scores on the virtual simulator compared to the Sawbones simulator. The only concern at this time is that the procedural measurement tool scores do not correlate between simulators. The newly developed virtual ulna surgical fixation simulator with haptics shows promise for helping surgical trainees learn and practice basic skills, but requires further modifications before it can attain the same standards as the current gold standard simulators.

Ulna Styloid Fractures have been historically dismissed as a relatively benign injury. However recent clinical and biomechanical research has suggested that primary repair of displaced ulna styloid avulsion fractures is advised as a means of stabilizing the radioulnar joint and preventing the disability associated with chronic radioulnar joint instability. Optimum fixation method was examined in this study using a human cadaveric model. A custom jig was designed to allow testing in radial/ulna deviation in varying degrees of wrist flexion and extension. Universal materials testing device was used to apply a maximum load of 150 N. Eight pairs of cadaveric wrists were tested. Constructs tested were 1.6mm K-wire fixation, Tension Band wiring and Screw Fixation. Fracture displacement was measured using a venire micrometer. Results: Displacement on forced radial deviation was maximum in neutral wrist position in all construct configurations. Displacement was minimized in 20 degrees wrist flexion. The optimum fixation method was 2 k-wires with tension band wiring. This study would suggest that the optimum fixation for ulna styloid fractures is a Tension band-wiring construct. If non-operative treatment is used we suggest that the wrist is immobilized in a position of wrist flexion to reduce tension on the ulna carpal ligament and prevent fracture displacement

Introduction. The main postoperative complications in fixation of ulna shaft fractures are non-union and implant irritation using currently recommended 3.5-mm locking compression plates. An alternative approach using a combination of two smaller plates in orthogonal configuration has been proposed. The aim of this study was to compare the biomechanical properties of a single 3.5-mm locking compression plate versus double plating using one 2.5-mm and one 2.0-mm mandible plate in a human ulna shaft fracture model. Method. Eight pairs human ulnar specimens with a standardized 10-mm fracture gap were pairwise assigned for instrumentation with either a single 3.5-mm plate placed posteriorly, or for double plating using a 2.5-mm and a 2.0-mm mandible plate placed posteriorly under the flexor muscles and laterally under the extensor muscles. All constructs were initially non-destructively biomechanically tested in axial compression, torsion, and bending, which was followed by cyclic torsional loading to failure. Interfragmentary movements were monitored by means of optical motion tracking. Result. There were no significant differences between the two plating techniques for axial stiffness (p=0.335), torsional stiffness in supination (p=0.462), torsional stiffness in pronation (p=0.307), medio-lateral bending stiffness (p=0.522), and antero-posterior bending stiffness (p=0.143). During cyclic torsional loading over the first 3000 cycles, there were no significant differences between the two plating techniques for shear displacement across the fracture gap, p=0.324. The numbers of cycles until clinically relevant failure of 5° angular deformation were 1366±685 for double plating and 2024±958 for single plating, which was statistically non-significantly different, p>0.05. The constructs treated with both plating techniques failed due to bone breakage at the most distal screw. Conclusion. From a biomechanical perspective double plating of ulna shaft fractures using a 2.5-mm and a 2.0-mm locking mandible plate demonstrated equivalent fixation strength as conventional plating using a single 3.5-mm locking compression plate

To develop a reliable and effective radiological score to assess the healing of isolated ulnar shaft fractures (IUSF), the Radiographic Union Score for Ulna fractures (RUSU). Initially, 20 patients with radiographs six weeks following a non-operatively managed ulnar shaft fracture were selected and scored by three blinded observers. After intraclass correlation (ICC) analysis, a second group of 54 patients with radiographs six weeks after injury (18 who developed a nonunion and 36 who united) were scored by the same observers. In the initial study, interobserver and intraobserver ICC were 0.89 and 0.93, respectively. In the validation study the interobserver ICC was 0.85. The median score for patients who united was significantly higher than those who developed a nonunion (11 vs 7, p<0.001). A ROC curve demonstrated that a RUSU ≤8 had a sensitivity of 88.9% and specificity of 86.1% in identifying patients at risk of nonunion. Patients with a RUSU ≤8 (n = 21) were more likely to develop a nonunion (n = 16/21) than those with a RUSU ≥9 (n = 2/33; OR 49.6, 95% CI 8.6–284.7). Based on a PPV of 76%, if all patients with a RUSU ≤8 underwent fixation at 6-weeks, the number of procedures needed to avoid one nonunion would be 1.3. The RUSU shows good interobserver and intraobserver reliability and is effective in identifying patients at risk of nonunion six weeks after fracture. This tool requires external validation but may enhance the management of patients with isolated ulnar shaft fractures

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.

Distal ulna fractures (DUF) are commonly associated with distal radius fractures (DRF). Recent evidence suggests that the presence and type DUFs may impact the outcomes of associated healing distal radius fractures. There is currently no standardised and validated classification system for characterising distal ulna fractures. The purpose of this study was to assess the validity of our newly created inclusive classification system for distal ulna fractures, shown to influence distal radius fracture outcomes in a previous study. A classification system for distal ulna fractures was devised based on fracture pattern and location. Type 1 fractures were those in the ulnar styloid, with type 1a involving its apex and Type 1b being in the body of the styloid; Type 2 fractures are proximal to the styloid and involve the ulnar fovea, with type 2t adopting a transverse pattern and type 2o an oblique pattern; Type 3 fractures involve the ulnar head; and type 4 fractures were those proximal to the head, with 4n being through the neck (including the physeal scar) and 4s involving the distal shaft. A questionnaire was distributed to all members of the Canadian Orthopaedics Association in both French and English, asking participants to evaluate 29 radiographic images of distal ulnar fractures. Only one answer was deemed to be correct for all but one radiograph, while for one radiograph there were three fracture types to be identified. There were 129 respondents to the questionnaire. For Type 1a fractures, of the 606 radiographs evaluated 90% answered correctly and 73% of the incorrect answers identified a Type 1b fracture pattern. For Type 1b fractures, of 600 radiographs, 83% were answered correctly, the incorrect answers including Types 1a and 2t fracture types. For Type 2t fractures, of 593 radiographs, 76% were answered correctly, and 90% of the incorrect answers identified a Type 1b fracture pattern. For Type 2o fractures, of 716 radiographs, 87% were answered correctly, and 91% of the incorrect answers were identified as either Type 4n or 2t. For Type 4n fractures, of the 465 radiographs evaluated 84% answered correctly and 80% of the incorrect answers identified a Type 4s fracture pattern. For Type 4s fractures, of the 355 radiographs evaluated 99% answered correctly and 100% of the incorrect answers identified a Type 4n fracture pattern. The results will guide the authors to further distinguish between the definitions of Types 1b and 2t, and 4n and 4s. The Canadian orthopaedic community has demonstrated how readily they can reproduce this new classification system, previously shown to be predictive of radiographic outcomes for the associated distal radius fractures. This new classification is an inclusive and simple way of characterising these fractures with high reliability. This provides treating physicians with a uniform way of describing these fractures, useful both in predicting outcomes and conducting future research

Purpose of Study:. To review the outcome of paediatric patients with radius and ulna fractures treated with titanium elastic nails. Description of methods:. Paediatric patients with radius and ulna fractures who fulfilled the criteria for TENS nailing were used. The criteria included failed closed reduction, instability (>15°angulation, >5°rotation) and open fractures. The patients were treated with retrograde TENS nailing of the radius and ulna. The patients were followed up at a paediatric orthopaedic outpatient clinic at 1, 3, 6 and 12 weeks with a final visit at 6 months. Data was collected at every visit looking at range of motion (pronation and supination), clinical and radiological signs of union and complications. Summary of results:. Over a 16 month period, 214 paediatric patients with radius and ulna fractures were seen and managed. Eleven of these patients were treated with TENS nails. The average age of the patient was 8.3 years. The average time to union was 8.5 weeks. The average range of motion at 6 months was pronation of 80°and supination of 73°. Two patients developed a compartment syndrome in the immediate post-operative period and were treated with a fasciotomy and skin grafting. No other complications were noted. Conclusion:. TENS nailing of paediatric radius and ulna fractures in unstable, irreducible and open fractures is a good treatment modality with good, early union of fractures and acceptable range of motion. It provides an excellent alternative to plating these fractures

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. The aim of this study was to utilize a national paediatric inpatient database to determine whether obesity influences the operative management and inpatient outcomes of paediatric limb fractures. Patients and Methods. The Kids’ Inpatient Database (KID) was used to evaluate children between birth and 17 years of age, from 1997 and 2012, who had undergone open and closed treatment of humeral, radial and ulna, femoral, tibial, and ankle fractures. Demographics, hospital charges, lengths of stay (LOS), and complications were analyzed. Results. Obesity was significantly associated with increased rates of open reduction and internal fixation (ORIF) for: distal humeral (odds ratio (OR) = 2.139, 95% confidence interval (CI) 1.92 to 3.44; p < 0.001); distal radius and ulna fractures (OR = 1.436, 95% CI 1.14 to 2.16; p < 0.05); distal femoral (OR = 2.051, 95% CI 1.69 to 3.60; p < 0.05); tibial and fibula shaft (OR = 2.101, 95% CI 2.10 to 3.50; p < 0.001); and ankle (OR = 1.733, 95% CI 1.70 to 2.39; p < 0.001). Older age was significantly associated with ORIF for all fractures (p < 0.05). LOS, hospital charges, and complications were significantly increased in obese patients following ORIF for upper and lower limb fractures (p < 0.05). Conclusion. Obese paediatric patients are more likely to undergo ORIF in both upper and lower limb fractures and have more inpatient complications. These findings may assist in informing obese paediatric fracture patients and their families regarding the increased risk for open operative fixation and associated outcomes.

Advancements in treating complications of operatively treated distal radius fractures. We will review tips and tricks to avoid complications associated with operative fixation of these complicated injuries. We will cover treatment of the distal radioulnar joint, associated distal ulna fracture, complications of malreduction and implant prominence. During this session, we will review the latest techniques for treating these complex distal radius fractures and how to avoid associated complications

Statistics of the clinical activities of an academic training unit was compiled from 1 January 2005 until 31 December 2005. The statistical study had three purposes. Firstly to determine the pathological profile of the patient population and to determine the distribution of patients who needed acute management versus elective surgery. Secondly to determine the needed staff establishment especially with the future anticipated expanding role of the public health sector in the management of orthopaedic patients. The last aim was to create a model of the clinical activities of a junior orthopaedic surgeon during one year of orthopaedic trauma training. Detailed statistics were compiled of all the clinical activities at the two hospitals. The one is a tertiary trauma centre, but also functions at a secondary trauma care level. The second hospital is a referral tertiary care orthopaedic hospital where elective surgery takes place. Furthermore the statistics were also compiled in such a way that detailed doctor activities could be processed from it. There were 181 spinal admissions of which 77 were treated surgically. 106 were treated conservatively. Elective spinal surgery consisted of 20 cases who needed reconstructive surgery and we managed 56 spinal infections. 1263 cases were admitted for orthopaedic trauma management of which 259 had surgery for femur fractures. A total of 250 tibia fractures were treated surgically and a total of 216 radius and ulna fractures. 117 arthroscopic knee procedures were done. A total of 168 arthroplasty cases were treated of which 47 were problem cases. Pathological profile was determined and gave guidance to clinical studies that should be undertaken. The numbers of some types of injuries that were managed are large. Staff establishment assessment can be done and the expansion of it can be motivated for. A model can be compiled for clinical activities of orthopaedic surgeons in training. Extracted from this statistical analysis an activity list was compiled for an orthopaedic surgeon in training. Amongst other minor cases and excluding Paediatric orthopaedic cases – Femur neck fractures 18, Femur fractures 29, Ankle fractures 53, Humerus fractures 12 and adult Supracondylar humerus fractures 9 and Radius Ulna fractures 34 were done

Aim: To evaluate the outcome of displaced distal radius fracture in children & review our practice. Methods: A retrospective review of case notes and radiographs of all children requiring orthopaedic intervention under general anaesthetic for displaced distal radius in our hospital over a period of 18 months (January 2005 to June 2006) was carried out. We had treated 72 fractures of the distal radius in same number of children. All but 3 cases were treated by primary closed manipulation & plaster immobilisation. Average age was 11.7 years (range 5 to 16 years). We looked at the re-displacement rate amongst these children that required a second procedure. We also sought predictive factors for redisplacement if any. Results: There were 22 female & 50 male patients. All the fractures were closed injuries with no distal neuro-vascular deficit. Of the 72 cases, 16 cases showed more than 50% initial displacement and 6 were completely displaced (off-ended). 9 cases had volar angulation. Redisplacement of fracture after initial satisfactory reduction was seen in 9 cases (12.7%) & required a second procedure. The secondary procedure involved closed reduction and percutaneous K wire fixation in 4 patients and open reduction in 2 cases. 3 cases had closed remanipulation & change of plaster. We reviewed the factors responsible for re-displacement after a closed reduction such as initial displacement, angulation, adequacy of initial reduction, associated ulna fracture, type of plaster, and initial post-operative images. Average age has been 12.7 years. 3 out of 5 (60 %) completely displaced fractures treated by closed reduction and manipulation required a second procedure. Only 1 in 16 cases of incompletely displaced fracture required a second procedure. Volar angulated fractures tend to redisplace after closed reduction, 3 out of 7cases (42 %) required a second procedure. Associated ulna fracture (22.7%) increased the risks of redisplacement. 5 out of 24 epiphyseal injuries redisplaced but these were either severely displacement or had volar angulation. 3 out of 4 cases (75 %)that were severely displaced had inadequate primary closed reduction & underwent a second procedure. Conclusion: We would like to conclude that despite achieving a very good initial reduction, offended distal radius fractures & those with volar displacement have high risk of re-displacement. Inadequate primary reduction has invariably resulted in requiring a second procedure. It is advisable to treat such cases by primary open reduction and K wire fixation in order to prevent redisplacement. In management of paediatric distal radius fractures, primary reduction with percutaneous Kirschner wire has better outcome and lower incidence of redisplacement in selected cases with features of complete displacement and volar angulation especially in the older age group (> 11 years)

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.

To evaluate effectiveness and safety of acute ulnar lengthening osteotomy in Madelung's deformity associated with Hereditary Multiple Exostoses (HME). Seventeen ulnas in 13 patients had acute ulnar lengthening for HME associated forearm deformity. Defined radiographic parameters were compared pre- and post-operatively using student's t-test; ulnar variance, carpal slip, radial bowing, radial articular angle. All complications were noted. Mean follow-up was 27 months (range 1.5 – 72months). An increase in ulna length by a mean of 15.4mm (range 4.5 – 29.3mm) was achieved acutely, corresponding to an increase of 9.3% of total ulnar length. Negative ulnar variance was improved from a pre-operative mean of 12.4mm (range 6.1–16.5mm) to a post-operative mean of 4.6mm (range 0–11.25mm) (p=<0.00001). Carpal slip was significantly improved by a mean of 2.2mm (p=0.02). No significant change in radial bowing (p=0.98) or radial articular angle (p=0.74) was observed. Inter-rater reliability was excellent (r=0.96, Pearson Correlation). Three patients required second procedures for recurrence of deformity at 18 months – 6 years following their primary operation. There were no incidences of compartment syndrome, neurovascular injury nor infection. One ulna fractured intra-operatively requiring a longer plate. One patient had a non union which united on revision surgery. Significant radiographic improvements in forearm and wrist alignment were seen with acute ulnar lengthening. The procedure is safe, with no compartment syndrome nor neurovascular injury and low complications rate. Recurrence rates in the skeletally immature patients are comparable to that reported with gradual lengthening. Acute ulnar lengthening for forearm deformity associated with HME has been demonstrated to be a safe, reproducible and effective surgical procedure

Distal radius and ulna fractures are a common paediatric injury. Displaced or angulated fractures require manipulation under anaesthetic (MUA) with or without Kirchner (K) wire fixation to improve alignment and avoid malunion. After treatment a proportion redisplace requiring further surgical management. This study aimed to investigate whether the risk of redisplacement could be reduced by introducing surgical treatment guidelines to ascertain whether MUA alone or the addition of K wire fixation was required. A cohort of 51 paediatric forearm fractures managed either with an MUA alone or MUA and K wire fixation was analysed to determine fracture redisplacement rates and factors which predisposed to displacement. Guidelines for optimal management were developed based on these findings and published literature and implemented for the management of 36 further children. A 16% post-operative redisplacement rate was observed within the first cohort. Redisplacement was predicted if an ‘optimal reduction’ of less than 5° of angulation and/or 10% of translation was not achieved and no K wire fixation utilised. Adoption of the new guidelines resulted in a significantly reduced redisplacement rate of 6%. Implementation of departmental guidelines have reduced redisplacement rates of children's forearm fractures at Great Western Hospital

Aims
