Introduction: There is no consensus regarding the range of immobilization in the conservative treatment of distal radius fractures (DRFs). Therefore, this systematic review and meta-analysis aimed to compare the clinical outcome of patients with DRFs treated conservatively with below- or above-elbow immobilization.Materials and Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, two independent reviewers searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Clinicaltrials.gov and World Health Organization International Clinical Trials Registry Platform in April 2020; a subsequent update search was conducted in April 2021. We identified all randomised controlled trials comparing two immobilization methods in DRFs. The primary outcome measures were the Disabilities of the Arm, Shoulder and Hand (DASH) or QuickDASH questionnaire scores in the short- and long-term (≤ and >six weeks, respectively) follow-up as well as the treatment failure rate. The secondary outcome measures were radiographic outcome, patient-rated wrist evaluation (PRWE) score, pain score and adverse events. Risk of bias was evaluated using the Cochrane Risk of Bias tool version 2. We used the Grading of Recommendations Assessment, Development and Evaluation approach to evaluate the quality of evidence.Results: The initial search revealed 1,775 records, and ten studies with 909 participants in total were included. There was no significant difference in DASH score in the short-term follow-up (4.99 lower, 95% confidence interval (CI): 10.45 lower to 0.46 higher; very low certainty) and treatment failure (risk ratio: 0.91, 95% CI: 0.59 to 1.40; low certainty). A clinically irrelevant but significant mean difference (0.83 lower, 95%CI: 1.64 lower to 0.03 lower; low certainty) was found in the DASH score in favour of below-elbow immobilization in the long-term follow-up. The overall risk of bias in DASH scores was high based on the measurement bias. Furthermore, there was no significant difference in secondary outcome measures.Conclusion: This meta-analysis did not demonstrate clinically meaningful difference between below- and above-elbow immobilization in terms of DASH score both in the short- and long-term follow-ups. However, overall certainty of evidence was considered very low, based on the very serious risk of bias, inconsistency and imprecision. Hence, there is a need for further higher quality research.Trial Registration Number: UMIN000040134 (4/14/2020). [ABSTRACT FROM AUTHOR]

Background: Forearm fractures are one of the top three most common fractures in children. Treatment often includes immobilizing the arm in a cast extending above the elbow to help maintain fracture reduction and alignment. Complications from circumferential casting can occur including swelling in the forearm that can lead to neurovascular complications. About 16% of children require splitting of the cast to relieve the increased pressure. Our study investigates the impact the location of the split has on cast bending stiffness in an above elbow cast model.Methods: A Sawbones© pediatric forearm model was used for application of a hybrid plaster-fiberglass cast to simulate treatment of a pediatric forearm fracture. The plaster was allowed to set for 20 minutes followed by application of a single fiberglass layer. The casts set for at least 24 hours and were then left intact or split along one of their 4 axes. Once categorized, the casts were subjected to biomechanical testing using an Instron ElectroPlus 10000 with a 3-point bending set up. The casts were tested until failure, and the load versus displacement curves were analyzed. Each category of casts was tested five times from both a volar and dorsal direction.Results: When loaded dorsal to volar, intact casts were significantly stiffer than those split along the dorsal, radial, or volar surfaces (p=0.0062, 0.0267, 0.0024 respectively). There was no significant difference when comparing one axis of longitudinal split to another. Intact casts showed a significantly higher load to failure than those split along the radial border (p=0.0168). When loaded volar to dorsal, intact casts were significantly stiffer than those split along any axis. Intact casts showed a significantly higher maximum load to failure than those split along the radial or ulnar border (p=0.0247, 0.0112 respectively).Conclusion: Consideration should be given to splitting above elbow casts along the volar or dorsal surface, as those split along the radial or ulnar border tend to have lower maximum load to failure.Clinical Relevance: To analyze the effect of splitting an above elbow cast on bending stiffness.

Purpose: Multiple trauma patients have a high risk of missed injuries. The main point of our study was to provide new epidemiological data on hand and forearm injuries in multiple trauma with a focus on those that were missed. Therefore, we used the database of the TraumaRegister DGU®.Methods: In this study, we evaluated anonymous data from 139931 patients aged 1-100 years with multiple trauma in the TraumaRegister DGU® of the German Society for Trauma Surgery from 2007 to 2017. Patients with hand and forearm injuries documented during hospital stay were identified and analyzed. We included fractures, dislocations, tendon injuries, nerve injuries and vessel injuries. Patients with missed hand and forearm injuries were compared with patients with primary diagnosed injuries in view of gender, age, ISS, Abbreviated Injury Score (AIS), Glasgow Coma Scale (GCS), Glasgow Outcome Scale (GOS), trauma mechanism type of injury, hospital stay, RISC II and mortality rate. Missed injuries were defined as injuries that were recently diagnosed and documented in the intensive care unit (ICU).Results: A total of 50459 multiple trauma patients (36.1%) had hand or forearm injuries, and 89472 patients (63.9%) had neither. Patients with hand injuries were younger and were more often involved in car and motorcycle accidents. Severe head trauma was evaluated less frequently, and severe thorax trauma was evaluated more often in patients with hand injuries. The times of diagnosis of hand injuries were documented in 10971 cases. A total of 727 patients (6.6%) with missed hand injuries were registered. The most commonly missed injuries in multiple trauma were 104 carpal fractures/dislocations (11.2%), 195 nerve injuries (25.4%) and 54 tendon injuries (11.4%). Predisposing factors for missing injuries were multiple diagnoses, primary care in the first hospital and direct from emergency room transfer to the ICU.Conclusion: In contrast to previous findings, severely injured patients, especially those with head injuries and GCS of ≤8, were not predisposed to have missed hand injuries compared to patients without severe head trauma. Special attention should be paid to younger patients after traffic accidents with multiple diagnoses and direct transfer to the ICU. [ABSTRACT FROM AUTHOR]

In the pediatric population supracondylar humerus fracture (SHF) is one of the most common injuries. Diagnosis is based on inspection and conventional radiography. SHFs should be classified according to the modified Gartland classification, which guides treatment. Non-displaced or minimally displaced fractures (Gartland type-I) should be treated non-operatively, completely displaced type III fractures require closed reduction and K-wire fixation. In type-II fractures, important landmarks, such as the anterior humeral line (Roger´s line), the shaft-physeal angle (Baumann´s angle) and the shaft condylar angle should be considered to guide treatment. Special attention has to be paid for potential rotational dislocation, which is indicated by a ventral spur. In such cases surgery is necessary. The degree of acceptable extension malpositioning depends on patient´s age. In 10-year-old children fractures with a shaft condylar angle of more than 15° are still suitable for non-operative therapy. Timing for surgery is controversially discussed. Postponing surgery to the next day seems reasonable if absence of pain, intact soft tissue and normal neurovascular status are present. Neurovascular complications are not uncommon, especially in Gartland type-III fractures and in cases with additional forearm injuries. A white hand without palpable pulse needs emergency surgery, the management of the pulseless pink hand is still controversially discussed. Different operative techniques exist for surgical treatment. The golden standard is closed reduction and percutaneous K-wire pinning. Crossed pinning seems to achieve best biomechanical stability. Since ulnar nerve injuries are reported to occur in 6% after medially inserting K-wires, lateral divergent insertion of two K-wires has been compared to crossed pinning fixation in several randomized controlled trials. Meta-analyses demonstrated a higher risk for ulnar nerve injury for the crossed pinning technique while risk for loss of fixation was higher in lateral only pinning. In both cases, K-wires should be removed 3-6 weeks after surgery with consolidation of the fracture. Clinical and radiological follow-up should be carried out at 3 weeks post fracture fixation to rule out loss of reduction. If this should occur, early revision surgery has been demonstrated beneficial. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study is to evaluate the incidence of neurovascular injuries, compartment syndrome, early postoperative infection as well as the injury factors predictive of neurovascular injury following ballistic fractures of the radius and ulna.Methods: A retrospective review was performed to identify all ballistic fractures of the radius and ulna in skeletally mature patients over a 5-year period at a single level-1 trauma center. Chart and radiographic review was performed to identify patient and injury demographics, associated neurologic or vascular injuries, and fracture characteristics. Fracture location was measured on computerized imaging software and fractures were grouped into bone(s) segments involved. Proximal, mid-diaphyseal, and distal locations were used for statistical analysis.Results: Fifty-six extremities in fifty-five patients were identified (mean age 32 years; male to female ratio 9:1). Overall incidence of neurologic injury was 50%, arterial injury 32%, and compartment syndrome 7.1%. Presence of a proximal third forearm fracture was associated with an increased risk for neurologic injury (p < 0.01), with an odds ratio of 5.7 (95% confidence interval, 1.7-18.4). Furthermore, all high velocity/energy ballistic injuries had associated neurologic injuries (p = 0.02).Conclusion: Ballistic forearm fractures result in high rates of neurovascular injury. Fractures caused by high velocity/energy firearms have extremely high rates of neurologic injury when compared with low velocity ballistic injuries. Ballistic fractures involving the proximal third of the radius or ulna are five times more likely to be associated with neurologic injury after a ballistic injury and should be assessed carefully on initial evaluation.

Introduction: The purpose of this study was to compare both bone diaphyseal forearm fractures in adolescent patients treated with plate fixation to patients treated with intramedullary fixation to identify differences in complications and outcomes.Materials& Methods: A retrospective study was performed on all adolescent patients with age between 10 and16 year and treated with intramedullary fixation or plate fixation for a diaphyseal both bone forearm fracture between 2005 and 2014. Demographic information and clinical data was collected. Radiographs were reviewed to evaluate post-operative radial bow magnitude and location, time to union, and residual angulation. Complications were graded using the modified Clavien-Dindo Classification system.Results: A total of 102 patients met the inclusion criteria. Of these, 32 were treated with plate fixation and 70 with intramedullary fixation. The intramedullary nail group had 55% of complications classified as major. There were no major complications in the plate fixation group (P = 0.1). The radial bow was significantly more distal and smaller in magnitude in the intramedullary fixation group (P < 0.01). Of the patients who underwent intramedullary fixation, 76% required an open reduction of at least one forearm bone. There was increased time to radiographic union in patients treated with intramedullary fixation when compared to those treated with plates, 68 days versus 58 days (P = 0.03). A second operation was necessary for 91% of patients treated with intramedullary fixation compared to only 3% of patients treated with a plate (P < 0.01).Conclusion: Diaphyseal forearm fractures in adolescent patients remain challenging injuries to treat. Forearm bony anatomy is not completely restored with intramedullary fixation. Results suggested an association towards increased complication rates and complication severity with intramedullary fixation.Level Of Evidence: Level 3 retrospective comparative study.

Background: Among several techniques proposed for the reconstruction of posttraumatic bone defects of the forearm, that of free vascularised fibular graft (FVFG) is one of the most widely used.Patients and Method: We study the long-term outcomes of 14 patients who underwent FVFG between 1994 and 2009, with a minimum follow up of 8 years and a maximum of 23 years (mean: 13.9 years). Demographic, clinical and radiological variables were collected retrospectively. The DASH scale was used for clinical assessment.Results: Fourteen patients were operated on by the same surgeon, applying FVFG for the reconstruction of posttraumatic bone defects of the forearm (three septic non-union of the ulna or radius, five radius fractures, two ulna fractures and four fractures of both bones). The maximum length of the defect was 11 cm and the minimum length was 6 cm. In four cases, reconstruction of the two bones was achieved using the double barrel technique, and in another four cases, an osteoseptocutaneous flap was used. Fixation was performed with 3.5 mm reconstruction plates in thirteen cases and with 3.5 mm screws in one case. Consolidation was obtained in 12 cases (85.7%) after an average time of 4.2 months (range: 2-6.5 months). In one case, consolidation of the proximal ulnar fracture site was not achieved, and in another, following the failure of reconstruction attempts, an arthrodesis was performed. At the end of the follow-up period, the patients had an average DASH score of 17.1 points (range 1.8-68.1).Conclusions: FVFG is a valid option for the reconstruction of posttraumatic bone defects of the forearm. Its use via the double barrel method or as an osteocutaneous composite graft enables the simultaneous reconstruction of both forearm bones and associated soft tissue injuries. Long-term follow-up of patients who have undergone this technique confirms its satisfactory functional and radiological results. [ABSTRACT FROM AUTHOR]

Malunion after forearm fractures are described to appear in 2% to 10% of cases. Reconstructive surgeries ensure adequate anatomical repositioning. Their importance derives from the fact that malunion can often lead to severe pain as well as deformities causing loss of function and aesthetic issues not only in the forearm, but also the wrist and elbow joint. In this paper a clinical case will be presented using a Patient Specific Instrument (PSI) as navigational aid for reconstructive surgery after malunion of a proximal ulnar fracture combined with allograft surgery of the radial head and radial condyle due to chronic traumatic radial head luxation (Monteggia fracture). A planning method based on symmetry is described and evaluated on twelve Computed Tomographic (CT) data sets of intact forearms. The absolute point to point deviation at distal end of the ulnar styloid process was used as a characteristic value for accuracy evaluation. It is 7.9±4.9mm when using only the proximal end of the ulna for registration. The simulated change of ulnar variance is -1.4±1.9mm. Design and concept of the PSI are proven in a clinical trial.

Introduction: The hoverboard, a self-balancing powered scooter, was introduced to the market in 2015 and quickly became one of the most popular purchases of the year. As with similar products, this scooter brought a host of concerns surrounding injuries. The purpose of this study is to determine the incidence of injuries that coincided with the popularity of hoverboard.Methods: The National Electronic Injury Surveillance System (NEISS) was queried from 2011 through 2015 for injuries related to scooters/skateboards, powered (product number, 5042), which includes the hoverboard. Patient data on sex, age, race, diagnosis, most severely injured body part, location where the injury occurred, and narrative of the injury were collected. The estimated injury incidence was calculated and compared on a yearly and monthly basis. Google Trends was used to determine the popularity of the hoverboard over the same time period.Results: During the 5-year study period, there were an estimated 47,277 injuries associated with the hoverboard. In 2015, there was an average 208% (range, 167-278%; standard deviation (SD), 51.8%) increase in the number of injuries compared to any of the previous 4 years. Further analysis of these injuries revealed a significant increase in the number of forearm (475%; range, 310-662%; SD, 159%), leg (178%; range, 133-206%; SD, 34%), and head and neck (187%; range, 179-197%; SD, 7.6%) injuries in 2015 compared to the previous 4 years. The most common type of injury in 2015 was a fracture (38.9%). Analysis of the sites of these fractures between 2014 and 2015 revealed a 752% increase in forearm fractures, which included over a 4000% increase in the number of wrist fractures.Conclusions: Given the number of injuries caused by these products, safety equipment, such as wrist guards and helmets, should be worn in an attempt to reduce the number of injuries. Additionally, this study highlights the importance of physicians keeping up to date with current trends to best advise their patients on safe practices. [ABSTRACT FROM AUTHOR]

Background: Nonunion is a rare but severe complication following forearm fracture in skeletally immature patients. The purpose of this study is to describe a case series of pediatric forearm nonunions treated at our Institute.Materials and Method: We retrospectively reviewed medical charts and radiographs of healthy children affected by post-traumatic nonunion of the forearm, from April 1992 to July 2015. An overall series of 15 cases was included in the study. Nonunion developed at ulna in 5 cases and at radius in 10 cases, at a mean time of 9 months (range 6-12) from fracture. Surgical treatment was performed in 14 cases out of 15. Stabilization of the nonunion was achieved with Kirschner wires (5 cases), plates (4 cases), rush rods (2 cases) and unilateral external fixator (3 cases). Iliac crest bone autograft was used in 11 cases, strut cortical bone allograft was used in 2 cases while in one case no bone graft was applied. In 2 cases an additional shortening osteotomy of the ulnar shaft was necessary to obtain adequate compression of the bone fragments. Cast immobilization was maintained for 6 to 8 weeks after surgery, then a brace was applied for further 8 to 12 weeks.Results: The average follow-up was 54 months (range 12-129); nonunion healed in 14 cases (93%) at an average time of 4 months (range 2-8). One case of nonunion did not heal 12 months after surgery; other complications included: radio-ulnar fusion and radial nerve palsy (1 case), myositis ossificans at the ulna (1 case), olecranon bursitis with residual elbow stiffness (1 case). One case was treated conservatively and healed after 18 months with residual malalignment.Conclusions: The present study describes the largest series of pediatric forearm nonunions in the current literature. Whether the surgical management of pediatric forearm nonunion provides satisfactory results in terms of bone healing, it may be accompanied by several complications, permanent sequelae and residual functional impairment. Any effort must be undertaken to avoid this serious complication. [ABSTRACT FROM AUTHOR]

Background: Several so-called casting indices are available for objective evaluation of plaster cast quality. The present study sought to investigate four of these indices (gap index, padding index, Canterbury index, and three-point index) as compared to a reference standard (cast index) for evaluation of plaster cast quality after closed reduction of pediatric displaced distal forearm fractures.Methods: Forty-three radiographs from patients with displaced distal forearm fractures requiring manipulation were reviewed. Accuracy, sensitivity, specificity, false-positive probability, false-negative probability, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio were calculated for each of the tested indices.Results: Comparison among indices revealed diagnostic agreement in only 4.7% of cases. The strongest correlation with the cast index was found for the gap index, with a Spearman correlation coefficient of 0.94. The gap index also displayed the best agreement with the cast index, with both indices yielding the same result in 79.1% of assessments.Conclusion: When seeking to assess plaster cast quality, the cast index and gap index should be calculated; if both indices agree, a decision on quality can be made. If the cast and gap indices disagree, the padding index can be calculated as a tiebreaker, and the decision based on the most frequent of the three results. Calculation of the three-point index and Canterbury index appears unnecessary. [ABSTRACT FROM AUTHOR]

Introduction: The majority of paediatric forearm fractures are treated using a circumferential splint, with prior manipulation as necessary. Plaster of Paris is often chosen for its ease of application, cost and proven reliability. Softcast is an alternative, providing a comfortable and water-resistant splint that can be removed without a plaster saw, and is in widespread use for immobilising buckle fractures. Softcast has not been recommended for acute unstable fractures. We established whether a Softcast splint could provide sufficient mechanical stability to control an unstable paediatric forearm fracture.Methods: A laboratory study was undertaken to compare the 3 point (kinking) and 4 point bending, and torsion loads to defined clinical failure points withstood by standardised 4-wrap POP compared to Softcast splints with 6-wrap, 4 wrap and reinforced 4-wrap configurations.Results: The load at clinically relevant failure of a 6-wrap Softcast forearm splint was 504N in 4 point bending, 202N in 3 point bending (kinking), and 11Nm in torsion (equalling 30.4%, 26% and 42.2% of the equivalent values for a circumferential 4-wrap POP). The 6-wrap Softcast was however stronger in all modes than a fibreglass-reinforced Softcast splint (previously 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, whereas POP was permanently deformed. 6-wrap Softcast splints were 4% lighter than POP.Conclusion: A 6-wrap Softcast splint provides adequate mechanical stability and protection for paediatric patients up to approximately 20kg, avoiding 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. Its cost may be offset by reducing the number and duration of hospital visits. [ABSTRACT FROM AUTHOR]

Background and Aim: The objective of this study is to introduce a novel percutaneous reduction technique for irreducible and difficult paediatric radius and ulna fractures in the distal forearm.Methods: From May 2010 to January 2012, the percutaneous joystick technique was conducted in 48 children who sustained irreducible or difficult radius and ulna fractures in the distal forearm. The series comprises 32 male and 16 female patients with an average age of 11 years (range, 7-15 years). Among them, 22 patients were <9 years of age. At the final follow-up, the range of motion of the wrist and grip strength of the hand were assessed. Measurements were compared to those on the opposite side. Wrist function was assessed with Mayo Wrist Score. Appearance and patient satisfaction were assessed using the 10-cm visual analogue scale. A p-value <0.05 was considered statistically significant.Results: Bone healing was achieved in all patients (radius: mean 3.5 weeks, range, 3-4 weeks; ulna: 3.8 weeks, range, 3-4 weeks), respectively. After an average follow-up period of 39 months (range, 36-45 months), patients had an average range of wrist motion of 74° (range, 65-86°) in flexion and 64° (range, 54-78°) in extension. The mean grip strength of the injured side was 33.7kg (13.8-47.6kg). The mean Mayo Wrist Score was 97 (range, 85-100), including 44 excellent and four good results. The mean scores of appearance and patient satisfaction on the forearm were 9.7 (range, 9-10) and 9.8 (range, 8-10), respectively. No significant difference was found regarding the range of motion and grip strength (p<0.05).Conclusions: The percutaneous reduction technique is a safe and valuable procedure for irreducible and difficult paediatric fractures of distal radius and ulna.

Introduction: In this cohort study, the surgical revision concept of open compression plating and autologous bone grafting with and without additional application of BMP for treatment of aseptic ulna and/or radius shaft nonunion was evaluated. The purpose was to evaluate the clinical and radiological outcome, and to determine any difference in osseous healing, range of time between revision surgery and bone healing, and postoperative complications between the cohort groups.Patients and Methods: Between 01/2005 and 03/2015, a prospective, randomised, controlled cohort study was performed in a Level I Trauma Centre. Forty-nine patients were treated with the diagnosis of aseptic diaphyseal ulnar and/or radial shaft nonunion using compression plating and autologous bone grafting. Additional biological augmentation using BMP-2 or BMP-7 was performed in 24 patients. Clinical and radiological follow-up was performed six weeks, three and six months after revision surgery in accordance to the system by Anderson.Results: The study group consisted of 38 men and 11 women with a median age of 44 years (range 19-77). Twenty-four out of 49 patients obtained compression plating either with autologous iliac crest bone grafting (11/24 patients) or cancellous bone grafting (13/24 patients) and additional application of BMP-2 (4/24 patients) or BMP-7 (20/24 patients). The remaining 25 patients did not receive any additional application of BMP, but autologous bone grafting. The median follow-up was 15 months (range 6-54 months). Forty-six out of 49 nonunion healed within 12 months after revision surgery with a median time to union of six months. The clinical outcome, as assessed using the system by Anderson, as well as osseous healing, duration of time interval between revision surgery and bone healing, and postoperative complications did not demonstrate significant differences between the cohort groups.Discussion: Atrophic/oligotrophic forearm nonunion healed irrespective of additional application of BMP combined with autologous bone grafting. For successful treatment, radical resection of fibrous nonunion tissue and internal compression plate fixation is required with the aim of achieving high degree of rigid stability. Also, correction of angular deformities, restoration of length, and precise axial alignment of the distal radio-ulnar joint are mandatory prerequisites to successfully achieve bone healing.

Background/objectives: Salvage repair after complex upper limb traumatic injury is surgically challenging due to underlying major arterial impairment with complicating a large-sized soft tissue defect. The purpose of this study was to evaluate the effectiveness and safety of using a giant-sized (≥100 cm(2)) flow-through venous flap for reconstruction of dual or multiple forearm, metacarpal, or digital arteries after complex upper limb traumatic injury.Methods: Seven patients were consecutively hospitalized for emergency salvage repair after complex upper limb traumatic injury between March 2012 and May 2014. The forearm and palmar artery defects were repaired using the calf great saphenous vein flap and the volar forearm venous flap, respectively.Results: The flow-through venous flap ranged from 9.5 cm × 12.0 cm to 12.0 cm × 20.0 cm (mean, 158.4 cm(2)) in size. The flaps and affected limbs survived uneventfully in five patients, with one patient experiencing distal flap marginal necrosis and a second patient requiring amputation of the affected limb. Computed tomography angiography showed patent vessels in all patients. The mean total active motion of the repaired fingers was 199.5° versus 258.8° for the contralateral counterpart (77.1%). The sensory return was determined to be S2 in 2 patients, S3 in 3 patients and S3+ in 1 patient. The disability scores for the arm, shoulder, and hand ranged from 4.6-18.2 (mean, 11.3), and the mean Michigan hand outcomes questionnaire score was 7.8 ± 0.9.Conclusions: The flow-through venous flap is an effective and safe treatment alternative for salvage therapy of a ≥100-cm(2) complex upper limb traumatic injury with dual or multiple major arterial impairment. This technique allows simultaneous reconstruction of dual or multiple artery injuries and an extensive soft tissue defect. Serious surgical site infection remains a major safety concern and necessitates radical debridement in complicating cases. [ABSTRACT FROM AUTHOR]

Introduction: Displaced paediatric forearm fractures are most often treated by manipulation under anaesthetic, followed by the application of a circumferential Plaster of Paris (POP) splint. Some surgeons choose to split the cast in order to facilitate immediate ''spreading'' with minimal distress to the patient, should the distal limb become compromised. Usually however, this does not occur, and the cast is completed at a later visit to the plaster room. Time, money and inconvenience could be saved if this modification was not necessary, and the final plaster would be lighter. Objective: To establish whether the mechanical properties of a split POP are sufficient to stabilise a forearm fracture, and protect the patient from further injury. Materials and methods: The repeatability of all tests was established on control samples before undertaking the trial. 42 standardised 8 layer POP cylinders of appropriate dimensions were fabricated, of which 21 were split longitudinally. The splints were subjected to non-destructive tests in 4-point bending (Bending), 3-Point Kinking (kinking) and torsion modes, and the load at clinically relevant end-points was recorded. These simulated the deformity at which the splint no longer provided adequate stability and alignment, or at which the wearer was no longer protected. The splints were then loaded to destruction to establish the mode of ultimate failure. Results: The mean loads at the clinical end points for split POP splints were: 1375 N in Bending, 544 N in Kinking and 12 Nm in Torsion (equalling 67.3%, 70.4% and 47.4% of the equivalent values for a circumferential splints). Loads were in excess of body weight for most paediatric patients. After ultimate failure, the proportion of casts that became unstable was similar (44% of full casts and 50% of split casts). Conclusion: Split POP splints which have not been spread, provide adequate stabilisation and protection of paediatric forearm fractures, and do not routinely require completion.

Background and aim Volar plating of distal radius fractures is one of the common procedures performed in trauma surgery. Flexor pollicis longus (FPL) rupture has been described as complication following volar plating of distal radius fractures. The aim of our study was to investigate the possible relation between parameters measured on post-operative radiographs and the occurrence of FPL ruptures. Materials and methods This was a case control study. The post-operative radiographs of 11 FPL rupture, and 22 non-FPL rupture patients were reviewed with respect to fracture reduction and plate position and the various parameters were calculated by five independent people. Logistic regression was used to examine the importance of the variables. Results We identified two significant factors to predict FPL rupture after volar plating of distal radial fractures. These were radial tilt and plate distance from the joint line. The odds ratio of ruptures was 0.74 (95% CI 0.57–0.95) for every degree of radial tilt <25° and 0.50 (95% CI 0.28–0.88) for every millimetre that the distal end of the plate was away from the volar lip of the distal radius at the wrist joint. Conclusion Post-operative radiographs could help us predict FPL rupture after distal radius volar plating. The findings also highlight the need for good fracture reduction and thoughtful placement of the volar plate intraoperatively to minimise the risk of FPL tendon rupture. [ABSTRACT FROM AUTHOR]

Abstract: Background: Both-bone diaphyseal forearm fractures constitute up to 5.4% of all fractures in children in the United Kingdom. Most can be managed with closed reduction and cast immobilisation. Surgical fixation options include flexible intramedullary nailing and plating. However, the optimal method is controversial. The main purpose of this study was to systematically search for and critically appraise articles comparing functional outcomes, radiographic outcomes and complications of nailing and plating for both-bone diaphyseal forearm fractures in children under 18 years. Methods: A comprehensive search of Medline, Embase and Cochrane databases using specific search terms and limits was conducted. Articles identified were thoroughly screened using strict eligibility criteria and eight retrospective non-randomised comparative studies were identified and reviewed. Results: There were no statistically significant differences in functional outcome or time to fracture union between plating and IM nailing. No consistent difference was found in complication rate, fracture angulation, shortening or rotation. Better cosmesis and shorter duration of surgery was noted in the IM nailing group. Post-operative radial bow was significantly abnormal in the IM nailing groups, but did not affect forearm movement. Conclusion: Based on similar functional and radiographic outcomes, nailing seems to be a safe and effective option when compared to plating for paediatric forearm fractures. However, critical appraisal of the studies in this review identified some methodological deficiencies and further prospective, randomised trials are recommended. [Copyright &y& Elsevier]

Introduction: Although limitation of pronation/supination following both-bone forearm fractures in children is often attributed to an angular malunion, no clinical study has compared pronation/supination and angular malalignment of the same child by analysis of prospectively collected clinical data. Aim: The purpose of this trial is to explore whether limitation of pronation/supination can be predicted by the degree of angular malalignment in children who sustained a both-bone forearm fracture. Methods: In four Dutch hospitals, children aged ≤16 years with a both-bone forearm fracture were prospectively followed up consecutive children for 6–9 months. At the final follow-up, pronation/supination and angular malunion on radiographs were determined. Results: Between January 2006 and August 2010, a total of 410 children were prospectively followed up, of which 393 children were included for analysis in this study. The mean age of the children was 8.0 (±3.5) years, of which 63% were male and 40% fractured their dominant arm. The mean time to final examination was 219 (±51) days. Children with a metaphyseal both-bone fracture of the distal forearm with an angular malalignment of ≤15° had a 9–13% chance of developing a clinically relevant limitation (i.e., <50° of pronation and/or supination), while children with an angular malalignment of ≥16° had a 60% chance. Children with diaphyseal both-bone forearm fractures with ≤5° of angular malalignment had a 13% chance of developing a clinically relevant limitation, which showed no significant increase with a further increase of angular malalignment. Conclusions: Children who sustained a both-bone forearm fracture localised in the distal metaphysis have a higher chance of developing a clinically relevant limitation of forearm rotation in case of a more severe angular malalignment, while children with a diaphyseal both-bone forearm fracture had a moderate chance of limitation, irrespective of the severity of the angular malalignment.

Abstract: Introduction: Both-bone forearm fractures in children frequently result in a limitation of pronation/supination, which hinders daily activities. The purpose of this prospective multicentre study was to investigate which clinical factors are related to the limitation of pronation/supination in children with a both-bone forearm fracture. Methods: In four Dutch hospitals, consecutive children (<16 years) who sustained a both-bone forearm fracture were included. Children were followed up for 6–9 months and data from questionnaires, physical examination and X-rays were collected. Univariate and multivariate logistic regression analyses were used to assess the relationship between limitation of pronation/supination (≥20°) and several clinical factors. Results: A group of 410 children with both-bone forearm fractures were included, of which 10 children missed the final examination (follow-up rate of 97.6%). We found that a re-fracture (odds ratio (OR) 11.7, 95% confidence interval (CI) 1.2; 118.5), a fracture in the diaphysis (OR 3.3, 95% CI 1.4; 7.9) and less physiotherapy during follow-up (OR 0.90, 95% CI 0.82; 0.98) were independently associated with a limitation of pronation/supination of 20° or more. Conclusions: These findings imply that a re-fracture and a diaphyseal located fracture were associated independently of each other with a limitation of pronation/supination in children with a both-bone forearm fracture. Furthermore, in children with severe limitation extensive physiotherapy is associated with better functional outcome. [Copyright &y& Elsevier]

Abstract: Introduction: Non-union rate in forearm fractures is generally less than 2% when a proper technique is used; this rate increases when ulnar lesions are involved. Patients and methods: We present a case series of seven young patients whose average age was 14 years (range 11–19 years) at the time of surgery and who presented with a forearm post-traumatic non-union that was previously treated in different ways (three isolated ulnar non-union, two isolated radial non-union and two combined). Average follow-up was 34 months (range 9–72 months). Surgical treatment began with the removal of the previous synthesis and with curettage of the non-union area. The Acumed ulnar rod, Acumed radial rod and Thalon elastic nail (all of them are unreamed and locked nails) together with autologous platelet-rich plasma (PRP) obtained with the Biomet System (concentration of 158.2×104 platelets/μL) were chosen to treat the patients. X-rays and clinical controls were conducted every 30 days until recovery. Results: All patients recovered: average recovery was 23 weeks from operation (range 16–36 weeks) and nails were removed 3 months after complete healing. Six patients had excellent results and one patient had a good result (Patient 2, forearm pronosupination 60–0–40 degrees). Discussion: The purpose of the case series was to establish a better way of treatment and to find a technique that could avoid the use of bone grafts, because obtaining autologous bone requires a further surgical procedure that can be really invasive depending on the amount of bone needed. Conclusion: All patients in the study showed complete recovery, with excellent clinical outcomes. Although there were only seven patients in this case series, and there is a need to analyse more patients, this study showed that the use of a specific locking nail system can provide proper stability to ulnar or radial atrophic non-union despite rotational forces, and when combined with autologous growth factors (PRP) is sufficient to promote bone healing in young patients without the necessity to take autologous bone grafts.

Abstract: Background: Paediatric forearm shaft fractures show an increasing incidence. The predictive factors of these fractures are not fully understood. Summer weather is suggested to have an effect on the risk of children's fractures. We studied the effect of rainfall, temperature and wind on paediatric forearm shaft fractures in summer. Methods: All 148 children's forearm shaft fractures in the geographic catchment district during the summer months in 1997–2009 were included. There were 1989 days in the study period. Daily meteorological readings captured the maximum daytime temperature, precipitation and wind speed. The direct daily association between fractures (yes/no) and different weather conditions was analysed in this population-based study. Results: The risk of forearm shaft fracture was 50% higher on dry days compared to rainy days (P =0.038). Temperature and wind speed had no statistically significant effect on fractures. Conclusions: The results give support for the presumption by the general public and professionals that summer weather affects children's fractures. A 1.5-fold increase in the risk is especially significant as the forearm shaft fractures are challenging to manage and prone to complications. Paediatric trauma units should prepare themselves for these severe injuries on dry summer days. [Copyright &y& Elsevier]

Summary: Background: The incidence of paediatric forearm fractures and their invasive operative treatment is increasing. Evidence supporting increased interest in internal fixation of forearm fractures has been controversial. We studied radiographic outcome and complications of both-bone diaphyseal middle-third forearm fractures according to the type of treatment. The purpose of the study was to determine if there is an advantage in invasive treatment over non-invasive treatment that supports the increasing trend towards invasive surgery. Materials and methods: All children and adolescents (<16 years) with both-bone diaphyseal middle-third forearm fractures in a geographic area with 86,000 children in 2000–2009 were included. There were 168 patients. The types of primary fractures and their malalignment and displacement rates were analysed. The fractures were classified as ‘severe’ or ‘mild’ according to radiographic findings. Radiographic fracture healing and alignment and the rate of complications were compared as regards invasive versus non-invasive surgery. Results: Just over a third of all patients suffered from some complication during follow-up. The overall complication rate was highest in the non-invasive treatment group (58%) and lowest in the intramedullary nailing group (24%) (P <0.001). The difference was significant as regards both mild and severe fractures. Nearly a third of the fractures in the non-invasive treatment group were re-reduced during follow-up. Two third of them were finally fixed invasively. Re-reduction after invasive fixation was rare (1.4%, P =0.001). Re-fracture was equally uncommon (7.1%) in both the invasive and non-invasive groups. Non-union was unusual (1.2%) and it was related to high-energy trauma or chronic disease. Nerve co-morbidity, scar problems, soft-tissue complications and compartmental syndrome were not problems in the study population despite the type of treatment. Conclusions: We found that the complication rate of diaphyseal forearm fractures was twice as common after non-invasive than after invasive treatment. The need of re-reduction after non-invasive treatment was remarkable. Nevertheless, bone healing was equally good despite the treatment. We conclude that intramedullary fixation of both-bone forearm fractures is a good mode of primary treatment of mild and severe middle-third diaphyseal both-bone forearm fractures.

Abstract: Introduction: Displaced metaphyseal both-bone fractures of the distal forearm are generally reduced and stabilised by an above-elbow cast (AEC) with or without additional pinning. The purpose of this study was to find out if re-displacement of a reduced stable metaphyseal both-bone fracture of the distal forearm in a child could be prevented by stabilisation with Kirschner wires. Methods: Consecutive children aged <16 years with a displaced metaphyseal both-bone fracture of the distal forearm (n =128) that was stable after reduction were randomised to AEC with or without percutaneous fixation with Kirschner wires. The primary outcome was re-displacement of the fracture. Results: A total of 67 children were allocated to fracture reduction and AEC and 61 to reduction of the fracture, fixation with Kirschner wires and AEC. The follow-up rate was 96% with a mean follow-up of 7.1 months. Fractures treated with additional pinning showed less re-displacement (8% vs. 45%), less limitation of pronation and supination (mean limitation 6.9 (±9.4)° vs. 14.3 (±13.6)°) but more complications (14 vs. 1). Conclusions: Pinning of apparent stable both-bone fractures of the distal forearm in children might reduce fracture re-displacement. The frequently seen complications of pinning might be reduced by a proper surgical technique. [Copyright &y& Elsevier]

Abstract: Introduction: Although there are three distinct compartments of the forearm, the typical approach for decompression of forearm compartment syndrome is a single incision fasciotomy of the volar compartment. This study had two purposes. The first purpose of this study was to investigate the compartment pressure changes within the forearm compartments following the creation of an acute compartment pressure using fresh-frozen cadaver forearm specimens. The second purpose was to compare the compartment pressure changes of the volar, dorsal, and mobile wad compartments at frequent intervals following a compartment fasciotomy of the forearm. Materials and methods: An experimental study of a laboratory model of acute forearm compartment syndrome was performed at a level-one, university-based trauma centre. Eight non-embalmed human forearms from 5 male and 3 female donors with an average age of 71 years (range, 51–91) were used. Compartment pressures in the volar, dorsal, and mobile wad compartments were recorded both before fasciotomy and 1, 10, 20, and 30min after fasciotomy. Results: A single incision volar fasciotomy was sufficient to decrease the elevated compartment pressures in the volar, dorsal and mobile wad compartments to near-baseline levels after 10min. The mean compartment pressures 30min post-fasciotomy in the volar, dorsal, and wad compartments were 2, 4, and 3mmHg, respectively. Discussion: In a laboratory model of an acute forearm compartment syndrome, a single compartment fasciotomy may be sufficient to decrease compartment pressures in the non-released compartments (dorsal and mobile wad). Further study is necessary before changes in clinical management can be recommended. [Copyright &y& Elsevier]

Abstract: Introduction: Minimally displaced metaphyseal both-bone fractures of the distal forearm in children are often treated with an above-elbow cast (AEC). Treatment with a below-elbow cast (BEC) could give more comfort, but might lead to fracture displacement reducing pronation and supination. Because this has not been systematically investigated, we set up a randomised multicentre study. The purpose of this study was to find out whether BEC causes equal limitation of pronation and supination but with higher comfort level, compared with AEC. Patients and methods: In four hospitals, consecutive children aged<16 (mean 7.1) years with a minimally displaced metaphyseal both-bone fracture of the distal forearm were randomised to 4 weeks BEC (n =35) or 4 weeks AEC (n =31). Primary outcome was limitation of pronation and supination 6 months after initial trauma. The secondary outcomes were cast comfort, limitation of flexion/extension of wrist/elbow, complications, cosmetics, complaints, and radiological assessment. Results: A group of 35 children received BEC and 31 children received AEC. All children attended for the final examination at a mean follow-up of 7.0 months (range 5.0–11.6 months). Limitation of pronation and supination 6 months after initial trauma showed no significant difference between the two groups [4.4° (±5.8) for BEC and 5.8° (±9.8) for AEC]. Children treated with BEC had significantly higher cast comfort on a visual analogue scale [5.6 (±2.7) vs. 8.4 (±1.4)] and needed significantly less help with dressing (8.2 days vs. 15.1 days). Six complications occurred in the BEC group and 14 in the AEC group. Other secondary outcomes were similar between the two groups. Conclusions: Children with minimally displaced metaphyseal both-bone fractures of the distal forearm should be treated with a below-elbow cast. [Copyright &y& Elsevier]

Abstract: Background: The incidence of children''s forearm fractures is increasing worldwide. This is different from the declining trend observed in the overall injury rate, and the reason for the increase is not known. Diaphyseal forearm fractures comprise 3–6% of all paediatric fractures, and they offer a challenge to their treatment. The purpose of this study was to evaluate the incidence of diaphyseal both-bone forearm fractures in children during the last decade in Northern Finland. Another objective was to study the background factors, treatment, and re-displacement of these fractures. Materials and methods: All 168 children (<16 years) admitted to our paediatric trauma centre due to diaphyseal both-bone forearm fractures during 2000–2009 were included. The type of injury, background factors, radiographics, treatments and re-dislocations were reviewed. The age-related incidence rates were evaluated. Results: The incidence of diaphyseal both-bone forearm fractures increased 4.4-fold (95% CI 2.0–10.8; P <0.001) between 2000 (8.2/100000) and 2009 (35.9/100000). The increase in the incidence was accelerating (P <0.001) and the overall increase was 338%. The incidence of surgical treatment for diaphyseal fractures increased 4.2-fold (95% CI 1.9–10.4, P =0.001), which is in relation to increasing number of fractures. However, internal fixation increased from 13.3% in 2000–2001 to 52.7% in 2008–2009 (P =0.015), as an alternative to conservative treatment. The re-displacement rate was high (29.9%) amongst the patients with conservative treatment compared to those who were invasively operated (1.4%) (P <0.001). The mean age of the patients increased by 2.4 years in the study period (P =0.019). Trampoline was the most important and still increasing reason for the fractures. At the beginning of the study, there were no trampoline-related fracture, but towards the end of the study 30–41% of the fractures were caused by a trampoline injury (P =0.004). Conclusions: There was an accelerating increase in the incidence of paediatric diaphyseal both-bone forearm fractures during the last decade. Trampoline was the most important and still increasing reason for these fractures. The mean age of the patients was increasing. Increasing proportion of diaphyseal both-bone forearm fractures was treated operatively. Re-displacement was unusual amongst operated cases. [Copyright &y& Elsevier]

Abstract: Introduction: The purpose of this investigation was to review the preliminary results and patients outcome following treatment with an anatomically preshaped LCP in patients with comminuted fractures of the proximal ulna. We hypothesized that this fixation system provides equal or superior results in fracture care when compared with other available plating devices, but results in better patient''s comfort due to its low-profile design. Patients and methods: Between 2007 and 2009, 15 patients with comminuted fractures of the proximal ulna including three posterior Monteggia fractures were managed with the preshaped LCP olecranon plate. The patients were invited for clinical examination at a mean duration of 16 months, retrospectively. Validated patient-oriented assessment scores involving the Mayo Elbow Performance Index (MEPI) and the shortened Disability of the Arm, Shoulder and Hand (Quick-DASH) score, postoperative range of motion, objective muscle-strengths testing and patient''s satisfaction were evaluated. All patients had follow-up radiographs. Results: Fourteen patients were available for evaluation. The mean arc of elbow motion was 129°. The mean MEPI was 97 with good results in two patients and excellent results in 12 patients. The mean Quick-DASH was 13. Thirteen of fourteen patients documented satisfaction with their elbow outcome. There was one patient with symptomatic hardware and one patient complained about deficit of motion. In four patients the hardware was removed including two patients with elective removal. Fourteen fractures healed with ulnohumeral congruity after a mean time to union of 11 weeks. One fracture non-union occurred without mechanical failure or loss of reduction. Conclusion: Anatomically preshaped LCP olecranon plating is an effective fixation method for comminuted fractures of the proximal ulna allowing reliable stability for early elbow motion. The functional results are comparable with formerly described plating systems. A low rate of symptomatic hardware removal suggests better patient''s compatibility. [Copyright &y& Elsevier]

Abstract: Background: Forearm fractures are common amongst children and often result in limited rotational function. In daily practice, pronation and supination of the arm are often visually estimated or measured using a conventional goniometer. The aim of this study was to compare the reliability of these two methods in paediatric patients who had previously sustained a forearm fracture. Methods: Intra- and interrater reliability of visual estimation and conventional goniometry were determined in 47 children who had previously sustained a forearm fracture. Results: Intra- and interrater reliability of visual estimation and conventional goniometry was fair to excellent, with intraclass correlation coefficients (ICCs) ranging between 0.75 and 0.94. In addition, the overall goniometer data consistently showed lower smallest detectable differences (SDDs) compared to the visual estimation data, also indicating better reliability for the goniometer method. Conclusions: A conventional goniometer is an easy, fast and reliable method to determine the pronation and supination in a child who had sustained a forearm fracture. If an uncooperative child hinders the measurement, visual estimation is a good second choice. Measurements are more reliable when repeated by the same professional. [Copyright &y& Elsevier]

Abstract: Bone bruising represents a new category of bone injury that can only be demonstrated by magnetic resonance imaging (MRI) with fat suppression. This study proposed the nature of non-radiographically evident injuries of the distal radius and wrist in children whose symptoms did not resolve after 5 weeks. We aimed to describe and classify the lesions and delineate the importance and potential complications of the injuries. Bone bruising was diagnosed in 20 patients (mean age: 11.6 years; range: 9–13 years). Bone bruises were classified according to anatomical location and whether they were solitary lesions or were combined with other injuries. Injuries of the distal radius were classified according to location: type 1 was localised to the metaphysis, close to the physeal plate; type 2 involved both the metaphysis and diaphysis; and type 3 extended on both sides of the distal radial growth plate. The type 1 injuries were consistent with complete, un-displaced Salter–Harris type I fractures, whilst type 3 lesions were potentially Salter–Harris type V injuries. Our data indicate that an MRI should be considered for a child with an injury to the distal radius or wrist whose symptoms do not resolve after 5 weeks of immobilisation. [Copyright &y& Elsevier]

Adults who suffer fractures of the distal radius are at increased risk of further osteoporosis related fractures and represent a high-risk group in whom therapies are available to reduce the risk. We have undertaken a prospective study of distal radius fracture patients over the age of 25 years to establish the extent of the problem in Dorset. All patients presenting with any forearm fracture to hospitals serving Dorset residents during 1 year were identified. Fracture type was assessed following scrutiny of the hospital notes. Analysis included calculation of rates per 10,000 population using Dorset Health Authority population estimates and seasonal variation. Ninety-six percent of all patients presented to three of the seven hospitals. One thousand six hundred and eighty-eight individuals with a diagnosis of forearm fracture were identified but only 1300 had a fracture of the distal radius. There was a female:male ratio of 3.9:1. In women, the incidence of distal radius fracture rose from a premenopausal baseline of 10 per 10,000 population per year to a peak of 120 per 10,000 population per year over 85 years. In men, the fracture incidence gradually increased from 10 per 10,000 before 65 years to 33 per 10,000 after 85 years. There was a detectable seasonal variation. Our data are in keeping with recent surveys in Europe and suggest that a change in the incidence of fracture of the distal radius with age has occurred over the last 30 years. [Copyright &y& Elsevier]
