Distal radius fractures (DRF) are the most common fracture type in all age groups combined. Unstable DRF may be surgically managed with volar or dorsal plate fixation. Dorsal plating has traditionally been associated with decreased range of motion (ROM). However, this assumption has not been recently assessed to determine whether functional ROM is achievable (approximately 54o of flexion and 60o of extension) with recent advances in lower profile dorsal plate design. The aim of this study was therefore to compare ROM and patient reported outcome measures between volar and dorsal plating methods for DRF. A meta-analysis was performed to directly compare ROM and DASH scores between dorsal and volar plate fixation for DRF. Separate literature searches for each plating method were performed using MedLine and EMBase on January 28, 2018. Exclusion criteria consisted of non-English articles, basic science articles, animal/cadaver studies, case studies/series, combined operative approaches, papers published more than 20 years ago and paediatric studies. Only articles with at least one year patient follow-up and a) ROM and AO distal radius fracture classification, or b) DASH scores were included. Raw data was extracted from all articles that met inclusion criteria to compile a comprehensive dataset for analysis. Descriptive statistics with z-score comparison for AO classification or a two-tailed independent samples t-test for ROM and DASH scores for dorsal versus volar plating were performed. Significance was defined as p < 0 .05. After rigorous screening, 6 dorsal plating and 43 volar plating articles met inclusion criteria for ROM/AO classification versus 6 dorsal plating and 44 volar plating articles for DASH scores. The weighted means of flexion (dorsal 54.9o, SD 9.3, n=257, volar 61.3o, SD 11.5, n=1906) and extension (dorsal 60.0o, SD 12, n=257, volar 62.8o, SD 11.4, n=1906) were statistically significantly different (both p < 0 .001) between the two plating methods. The volar plating group had a significantly higher proportion of AO type C fractures (dorsal 0.5, n =169, volar 0.6, n=1246, p < 0 .001). The weighted means of reported DASH scores were not significantly different between dorsal (14.01, SD 14.8) versus volar (13.6, SD 12.8) plating (p=0.54). Though mean wrist flexion and extension were statistically different between the dorsal versus volar plating methods, the difference between group means was less than 5o, which is unlikely to be clinically significant. Additionally, we did not find a significant difference in DASH scores between the two plating methods. Taken together, these findings imply that the statistical difference in ROM outcomes are likely not clinically significant and should therefore not dictate choice of plating method for fixation of DRF

The ITS volar radial plate (Implant Technology Systems, Graz/Austria) is a fixation device that allows for the distal locking screws to be fixed at variable angles (70°-110°). This occurs by the different material properties, with the screws (titanium alloy) cutting a thread through the plate holes (titanium). We present our experience with the ITS plate. We retrospectively studied 26 patients who underwent ITS plate fixation for unstable multifragmentary distal radial fractures (AO types A3, B2, B3, C2, C3). The surgery was performed either by a consultant orthopaedic hand surgeon or senior registrar. A volar approach was used every time and 10 cases required synthetic bone grafting. Post-operatively they were immobilised for an average of 2.5 weeks. The 26 patients had a mean age of 58 and the dominant side was affected in 46% of cases. 5 cases were open fractures and 10 cases followed failed manipulation under general anaesthesia. The average interval between injury and surgery was 7 days. Union was achieved in all cases. No implant infections, failure or tendon rupture/irritation occurred. There were two fractures which loss reduction, of which one required revision surgery. There was one case of CRPS. The six month average DASH score was 27.5. We consider the ITS plate a technically easy plate to use and a reliable implant at early follow-up. We value the versatility of its variable angle screw fixation ability for complex intra-articular distal radial fractures

Background

Implants based on the polyetheretherketon (PEEK) polymer have been developed in the last decade as an alternative to conventional metallic devices. PEEK devices may provide several advantages over the use of conventional orthopedic materials, including the lack of metal allergies, radiolucency, low artifacts on magnetic resonance imaging scans and the possibility of tailoring mechanical properties. The purpose of this study was to evaluate the clinical results at mean 24-month follow-up using a new plate made of carbon-fiber-reinforced polyetheretherketon (CFR-PEEK) for the treatment of distal radius fractures.

Aims of study. To assess and compare the functional, radiological and cosmetic results as well as patient satisfaction in patients treated with the IMN Device Vs Volar Locking Plate. Method. All patients who presented to our institution with extra articular distal radius fractures and met the inclusion criteria were invited to take part in the study. The patients were randomly allocated to two groups, those who underwent intramedullary (IMN) distal radius fixation using the Sanoma Wrx Distal radius nail and those who underwent fixation using a volar locking plate. The patients were then followed up at 2 weeks, 6 weeks, 3 months, 6 months and 1 year. The radiological parameters, ie radial height, inclination and tilt were compared as well as the functional outcomes by means of DASH score. The range of motion of the wrist was compared as well as the scar size. Complications were reviewed. Results. We present our early results. Currently we have included 9 patients in the IMN group and 7 patients in the volar plate group with follow-ups longer than 3 months. Results show smaller scars (2.5 vs 6.7cm), comparable flexion and extension (40 vs 40 and 45 vs 40), slight improvements in pronation and supination (80 vs 75 and 85 vs 80) in the IMN compared to the volar plate. Radial and ulnar deviation is comparable. The radiological parameters showed slight improvements in the radial height (2.5 vs 2.2 mm), inclination (3.6 vs 3.2 degrees) and tilt 13,7 vs 12 degrees) with the IMN. Dash scores will be compared at 6 months. Conclusion. Intra medullary nailing of the distal radius seems to compare to volar plating in terms of radiological parameters and rotational stability but has the added benefit of early range of motion, minimal invasive technique, less post op pain and less complications such as tendon irritation. NO DISCLOSURES

Objective. The aim of this retrospective study is to assess the functional and radiological outcome of a multi-planar corrective osteotomy, distraction and locking fixed angle volar plate as the standard of treatment of distal radius mal-unions that require multi-planar correction. Methods. We conducted a retrospective study on 13 consecutive patients – 4 males, 9 females (mean age 49). All patients underwent volar approach, open wedge distraction osteotomy locking fixed angle volar plate and cancellous bone grafting Radiographic measurements and functional assessments were taken preoperatively, 3, 6 months and one year. Results. Time to surgery from the original fracture had a mean of 17.4 months (range 8–36 months). Mean follow-up was 16.4 months (range from 6 to 45 months). Osteotomy healing time was 11.3 weeks on average. All radiographic measurements improved postoperatively, ten patients had an average of 18.84 degrees of dorsal tilt which was corrected to a volar tilt of 9.17 degrees on average. Ulna variance was initially positive in all patients with an average of 2.6 mm which was corrected to less than one (0.96 mm); three patients had radial angulations of 20.6 degrees on average, which were fully corrected postoperatively. Flexion-extension arc has improved with significant difference and so has the grip and pinch strength. The average DASH and SF12 scores has shown figures comparative to the normal population post deformity correction. Complications included one case of low grade wound infection and one case of postoperative symptoms of carpal tunnel syndrome. Conclusion. The described technique is a useful means to correct distal radius anatomy and function; however patients should be aware that it is not always possible to regain full function and anatomy

Distal radius fractures are the most common upper extremity injury, and are increasingly being treated surgically with pre-contoured volar-locking plates. These plates are favored for their low-profile template while allowing for rigid anatomic fixation of distal radius fractures. The geometry of the distal radius is extremely complex, and little evidence within the medical literature suggests that current implant designs are anatomically accurate. The main objective of this study is to determine if anatomic alignment of the distal radii corresponds accurately with modern volar-locking plate designs. Additionally, this study will examine sex-linked differences in morphology of the distal radius. Segmented CT models of ten female cadaver (mean age, 88.7 ± 4.57 years, range, 82 – 97) arms, and ten male cadaver (mean age, 86 ± 3.59 years, range, 81 – 91) arms were created. Micro CT models were obtained for the DePuy Synthes 2.4mm Extra-articular (EA) Volar Distal Radius Plate (4-hole and 5-hole head), and 2.4mm LCP Volar Column (VC) Distal Radius Plate (8-hole and 9-hole head). Plates were placed onto the distal radii models in a 3D visualization software by a fellowship-trained orthopaedic hand surgeon. The percent contact, volar cortical angle (VCA), border and overlap of the watershed line (WSL) were measured. Both sexes showed an increase in the average VCA measure from medial to lateral columns which was statistically significant. Female VCA ranged from 28 – 36 degrees, and 38 – 45 degrees for males. WSL overlap ranged from 0 – 34.7629% for all specimens without any statistical significance. The average border distance for females was 2.58571 mm, compared to 3.52411 mm for males, with EA plates having a larger border than VC plates. The border distances had statistically significant differences between the plate types, and was approaching significance between sexes. Lastly, a maximum percent contact of 21.966 % was observed in specimen F4 at a 0.3 mm threshold. No statistical significance between plate or sex populations was observed. This study investigated the incoherency between the volar cortical angle of the distal radius, and the pre-contoured angle of volar locking plates. It was hypothesized that if the VCA measures between plate and bone were unequal then there would be an increase in watershed line overlap, and decrease in percent contact between the surfaces. Our results agreed with literature, indicating that the VCA of bone was larger than that of the EA and VC pre-contoured plates examined in this study. With distal radius fracture incidences and prevalence on the rise for elderly female patients, it is a necessity that volar locking plates be re-designed to factor in anatomical features of individual patients with a particular focus on sex differences. New designs should focus on providing smaller head sizes that are more accurately tailored to the natural contours of the volar distal radius. It is recommended that future studies incorporate expertise from multiple surgeons to diversify and further understand plate placement strategies

Distal radius fracture is one of the most common fractures in older women (∼70,000 cases annually in Canada). Treatment of this fracture has been shifting toward surgery (mainly volar locking plate (VLP) technology), which significantly enhances surgeon's ability to maintain correction. However, current surgical outcomes are far from perfect. There is a need for an implant which maintains the corrected position (reduction), minimizes soft tissue disruption, and is technically easy to perform. A novel internal, composite-based implant was designed to achieve these ends. It is unclear, however, whether this novel implant offers similar fracture fixation as the VLP. As such, the objective of this research was to evaluate the fracture stability (assessed by calculating change in fracture length) of the novel implant and VLP under cyclic fatigue loading. Specimens: Seven radius specimens derived from older female cadavers (mean = 82.3 years, SD = 11.3 years) were used for the experiment. Preparation: A standardized dorsal wedge was removed from the cortex. The distance from the proximal and distal transverse osteotomies was 10 mm and was positioned 20 mm proximal to the tip of the radial styloid. The osteotomy removed all load-bearing capabilities of bone, equivalent to a worst-case-scenario for DRF fixation. Simulated Loading: The proximal end of the radii was potted (fixed) and positioned in a material testing system. To mimic natural loading conditions, hands were cycled between −30°/30° flexion/extension, at 0.5 Hz, for 2000 cycles, while tension load was applied to the tendons (25-N constant force per tendon, 100-N in total). Mechanical testing outcomes: A position tracking sensor used to measure change in fracture length. This change, as a function of number of cycles, was used to assess implant resistance to fatigue loading. Statistical Analysis: A paired student t-test was used to compare the change in fracture length. Level of significance was determined as 5% (p < 0.05). Changes in fracture fracture-length for both the novel implant and plate is shown in Table 1. The paired t-test indicated significant differences between the two groups in terms of change in fracture length (p = 0.026). The outcome of the novel implant ranged from very stable (change in fracture-length = 0.01 mm) to highly un-stable (2.88 mm). We believe the reason for this variance, at least in part, originates from the surgical procedures. Presumably, given that one very strong stabilization (0.01 mm) and one acceptable stabilization (0.37 mm) was obtained, future research directed towards surgical procedures may improve fracture stability.

Distal radius fractures are the most common osteoporotic fractures among women. The treatment of these fractures has been shifting from a traditional non-operative approach to surgery, using volar locking plate (VLP) technology. Surgery, however, is not without risk, complications including failure to restore an anatomic reduction, fracture re-displacement, and tendon rupture. The VLP implant is also marked by bone loss due to stress-shielding related to its high stiffness relative to adjacent bone. Recently, a novel internal, composite-based implant, with a stiffness less than the VLP, was designed to eradicate the shortcomings associated with the VLP implant. It is unclear, however, what effect this less-stiff implant will have upon adjacent bone density distributions long-term. The objective of this study was to evaluate the long-term effects of the two implants (the novel surgical implant and the gold-standard VLP) by using subject-specific finite element (FE) models integrated with an adaptive bone formation/resorption algorithm. Specimen: One fresh-frozen human forearm specimen (female, age = 84 years old) was imaged using CT and was used to create a subject-specific FE model of the radius. Finite element modeling: In order to simulate a clinically relevant (unstable) fracture of the distal radius, a wedge of bone was removed from the model, which was approximately 10 mm wide and centered 20 mm proximal to the tip of the radial styloid. Bone remodeling algorithm: A strain-energy density (SED) based bone remodeling theory was used to account for bone remodeling. With this approach, bone density decreased linearly when SED per bone density was less than 67.5 µJ/g and increased when it was more than 232.5 µJ/g. When it was in the lazy zone (67.5 to 232.5 µJ/g), no changes in density occurred. Boundary conditions: A 180 N quasi-static force representing the scaphoid, and a 120 N quasi-static force representing the lunate was applied to the radius. The midshaft of the radius was constrained. FE outcomes: To examine the effects of stress shielding associated with each implant, the long-term changes of bone density within proximal transverse cross-sections of radius were inspected. The regional density analysis focused on three transverse cross-sections. The transverse cross-sections were positioned proximal to the subchondral plate, and were distanced 50 (cross-section A), 57 (cross-section B), and 64 mm (cross-section C) from the subchondral endplate. For both implants in all three cross-sections, cortical bone was reserved completely at the volar side. On the dorsal side, the cortical bone was completely resorbed in the VLP model. In all cross-sections, the averaged resultant density was higher for the “novel implant”. The difference ranged from 33% (cross-section A) to 36% (cross-section C) in favor of the “novel implant”. On average, the density values of the novel implant were 34% higher in transverse cross-sections (A, B, and C). This study showed that the novel implant offered higher density distributions compared to the VLP, which suggests that the novel implant may be superior to the VLP in terms of avoiding stress shielding

The aim of this study is to compare functional, clinical and radiological outcomes in K-wire fixation versus volar fixed-angle plate fixation in unstable, dorsally angulated distal radius fractures. Fifty-four adult patients with an isolated closed, unilateral, unstable, distal radius fracture were recruited to participate in the study. Only dorsally displaced fractures with no articular comminution were included. Patients were randomised to have their fracture treated with either closed reduction and K-wire fixation (3 wires) or fixed-angle volar plating. Both groups were immobilised in a below elbow cast for six weeks. The wires removed in the outpatients at six weeks and both groups were referred for physiotherapy. Independent clinical review was performed at three and six months post injury. Functional scoring was performed using the DASH and Gartland and Werley scoring systems. Radiographs were evaluated by an independent orthopaedic surgeon. Twenty-five patients were treated with a plate and twenty-nine with wires. There were no complications in the plate group. There were 9 complications in the K-wire group with 3 patients requiring a second operation (1 corrective osteotomy for malunion, 1 median nerve decompression and 1 retrieval of a migrated wire). The remaining complications included: 5 pin site infections (3 treated with early pin removal and 2 with oral antibiotics only), and 1 superficial radial nerve palsy. There were no tendon ruptures. Both groups scored satisfactory functional results with no statistical difference. There was a statistically significant difference in the radiological outcomes with the plate group achieving better results. We conclude that in unstable dorsally angulated distal radius fractures volar fixed-angle plate fixation is able to achieve comparable functional results to K-wire fixation with better radiological results and fewer complications. This has resulted in a change in our clinical practice

Despite the variety of implants or techniques that exist to treat displaced distal radial fractures, the majority fail to provide sufficient stability to permit early functional recovery. However, locking plates have the advantage over other implants in that locking screws add considerably to the overall stability. The aim of this study was to assess the functional outcome of patients with displaced distal radial fractures treated with a volar distal radial locking plate (Synthes). During a two year period, details of 98 patients admitted to our unit with inherently unstable dorsally displaced distal radial fractures treated with volar locking plates were collected prospectively. For the purpose of this analysis, only those patients (55) with unilateral fracture, able to attend the study clinic at 6 months post-injury were considered. Patients were immobilised in wool and crepe for a 2 week period. The group consisted of 15 males and 40 females with an average age of 54 (28 to 83). At 6 months, patients' perceived functional recovery averaged 80%. Objective assessment was considered in relation to the uninjured side: grip strength 73%; pinch strength 83%; palmarflexion 77%, dorsiflexion 80%; radial deviation 74%; ulnar deviation 74%; pronation 93%, and supination 92%. Seven patients complained of symptoms relating to prominent metalwork. Good/excellent early subjective and objective functional recovery was made following open reduction and internal fixation using volar locking plates of dorsally displaced distal radial fractures. We suggest that objective assessment of grip strength and dorsiflexion can be used as a measure of patient perception of function

BACKGROUND. In our institution we use the Winklestabile volar locking plate for operative fixation of distal radius fractures. This study aims to assess subjective and objective outcomes using this method of treatment. METHODS. A total of 21 patients who underwent ORIF of distal radius fractures with the Winklestable plate in 2005 with a minimum follow up of 12 months were assessed using the Patient Rated Wrist Evaluation (PRWE) questionnaire and the Disabilities of the Arm Shoulder and Hand (DASH) score. Range of wrist movement (ROM), grip strength and pinchgrip strength were assessed by comparison with the unaffected wrist. RESULTS. Mean age was 64.34yrs (median 65.74, interquartile range (IQR) 59.11 – 71.80). The mean time from presentation to surgery was 2.0 days (median 1.0, IQR 1.0 - 2.0). Radiological union was confirmed after a mean of 83.3 days (median 83.0, IQR 83.0 – 90.0). Twenty fractures followed low energy trauma and 19 were closed. Eleven fractures were extra-articular. None, minimal or mild PRWE scores were achieved in 18 (86%) patients for pain, 15 (71%) for specific functions and 19 (90%) for usual functions. Six patients scored zero on the DASH score (mean 17.0, median 4.0, IQR 0.0-23.0). There was no difference in grip strength (pounds) in two patients (mean 10.6, median 6.0, IQR 4.0-15.0) and no difference in pinchgrip strength in nine patients (mean 1.0, median 0.5, IQR 0.0-1.5). Sixteen patients (76%) reported no complications. Two patients required extra postoperative physiotherapy. One suffered extensor polis longus rupture. One reported generalised wrist pain. One reported difficulty pushing down with affected hand. One reported pain on movement. No patients required revision surgery. CONCLUSION. In our institution, we believe that ORIF for distal radius fractures using the Winklestabile distal radius locking plate achieves satisfactory subjective and objective results with an acceptable rate of complications

Distal radius fractures (DRF) are common and the indication for surgical treatment remain controversial in patients higher than 60 years old. The purpose of the study was to review and analyze the current evidence-based literature.

We performed a systematic review and meta-analysis according to PRISMA guidelines in order to evaluate the efficacy of volar locking plating (VLP) and conservative treatment in DRF in patients over 60 years old. Electronic databases including MEDLINE, CENTRAL, Embase, Web of science and Clinical Trial.gov were searched from inception to October 2020 for randomized controlled trials. Relevant article reference lists were also passed over.

Two reviewers independently screened and extracted the data. Main outcomes included functional status: wrist range of motion, validated scores and grip strength. Secondary outcomes include post-operative complications and radiologic assessment.

From 3009 screened citations, 5 trials (539 patients) met the inclusion criteria. All trials of this random effect meta-analysis were at moderate risk of bias due to lack of blinding. Differences in the DASH score (MD −5,91; 95% CI, −8,83; −3,00), PRWE score (MD −9.07; 95% CI, −14.57, −3.57) and grip strength (MD 5,12; 95% CI, 0,59-9,65) were statistically significant and favored VLPs. No effect was observed in terms of range of motion. Adverse events are frequent in both treatment groups, reoperation rate is higher in the VLP group.

VLP may provide better functional outcomes in patients higher than 60 years old. More RCT are still needed to evaluate if the risks and complications of VLP outweigh the benefits.

We present the results of a bi-centre, retrospective study examining the clinical, functional and radiological outcomes of distal radius fracture fixation with the Aptus locking plates and Tri-Lock® variable angle locking screws. We assessed 61 patients with distal radius fractures with a minimum of six months follow-up. Functional assessment was made using the DASH score. We measured wrist range of movement and grip strength, and reviewed radiographs to assess restoration of anatomy, fracture union and complications. All fractures united within six weeks. Mean ranges of movement and grip strength were only mildly restricted compared to the normal wrist. The mean DASH score was 18.2. Seven patients had screws misplaced outside the distal radius although 3 of these remained asymptomatic. Five other patients developed minor complications. Variable angle locking systems benefit from flexibility of implant positioning and may allow enhanced inter-fragmentary reduction for accurate fixation of intra-articular fractures. However, variable-angle systems may lead to increased rates of screw misplacement.

Volar Locking Plates (VLP) have revolutionised the treatment of distal radius fractures allowing the anatomic reduction and stable fixation of the more comminuted and unstable of fractures. The benefits of this in terms of range of movement (ROM), pain and earlier return to work and daily activities is documented. However we were interested in was what improvements in wrist function patients made from 6 to 12 months after injury?

Tendon injuries after distal radius fractures Introduction: Tendon injuries after distal radius fractures are a well-documented complication that can occur in fractures managed both operatively and non-operatively. The extensor tendons, in particular the extensor pollicis longus (EPL) tendon, can be damaged and present late after initial management in a cast, or by long prominent screws that penetrate the dorsal cortex and cause attrition. Similarly, a prominent or distally placed volar plate can damage the flexor pollicis longus tendon (FPL). The aim of our study was to evaluate the incidence of tendon injuries associated with distal radius fractures. We conducted a single centre prospective observational study. Patients aged 18–99 who presented with a distal radius fracture between May 2018 to April 2020 were enrolled and followed-up for 24 months. Tendon injuries in the group were prospectively evaluated. Results: 199 patients with distal radius fractures were enrolled. 119 fractures (59.8%) had fixation and 80 (40.2%) were managed incast. In the non-operative group, 2 (2.5%) had EPL ruptures at approximately 4 weeks post injury. There were no extensor tendon ruptures in the operative group. In the operative group, there were 6 (5%) patients that required removal of metalware for FPL irritation. At the time of operation, there were no tendon ruptures noted. Within the operative group we evaluated plate prominence using a previously described classification (Soong et al.). 5 of the 6 patients (83%) with FPL irritation had Grade 3 prominence. The incidence of both flexor and extensor tendon injury in our cohort was 4%, extensor tendon rupture was 1% and flexor tendon rupture was avoided by early metalware removal. This study demonstrates tendon injuries are not uncommon after distal radius fractures, and close examination and follow-up are necessary to prevent eventual rupture. Plate prominence at the time of fixation should be minimised to reduce the risk of rupture

Introduction. Unstable dorsal fracture/dislocation of PIP joint is a complex injury and difficult to treat. Different treatment methods have been described with varying results. We describe a novel technique to combine fracture fixation with volar plate repair using micro anchor suture. Material and methods. Between July and December 2005, 11 consecutive patients with unstable dorsal PIP joint dislocations underwent open reduction and volar plate repair using our technique. Nine patients had dorsal fracture dislocations and two had open dislocations. All patients were males and their average age was 26 years. All patients were reviewed with the minimum follow up of 12 months. The pain score, range of movements and grip strength were recorded and compared to the normal side. Operative Technique. Volar approach was made using a semi Brunar incision. One or two micro bioabsorbable anchors (Mitek, Ethicon Ltd, UK) were used to stabilise the joint and repair the volar plate. Additional anchor was used to repair the collateral ligament when indicated. Post-operatively the hand was rested in Edinburgh functional splint for 10 days followed by active and assisted range of movements under hand physiotherapist supervision. Results. 10 out 11 patients had excellent pain relief. The average range of movement of the PIP joint was 100 degrees. One patient with neglected PIP joint fracture dislocation for 10 weeks had mild residual pain and stiffness. The mean grip strength was 87% of that of contralateral normal side. All patients returned to their same work as before. 8 out of 9 patients returned to play their regular sports at the same level. All patients were satisfied with the functional outcome. Conclusion. Combined fracture fixation and volar plate repair through anterior approach using micro bioabsorbable anchors appears to be very effective way of treating this otherwise complex unstable fracture/dislocation of PIP joint

Introduction. The distal radius is the most frequently fractured bone in the forearm with an annual fracture incidence in the UK of about 9–37 in 10,000. Restoration of normal anatomy is an important factor that dictates the final functional outcome. A number of operative options are available, including Kirschner wiring, bridging or non-bridging external fixation and open reduction and internal fixation by means of dorsal, radial or volar plates. We designed this study to analyse the clinical and radiological outcome of distal radial fracture fixation using volar plating. Materials/Methods. Thirty-seven patients with distal radius fractures undergoing open reduction and internal fixation using volar plates were included. Tilt of the fractured distal radial fragment was recorded from the initial radiograph and classification of fractures was done using the Orthopaedic Trauma Association system. The QuickDASH questionnaire was used for evaluation of symptomatic and functional outcome six months to one year after surgery. The radiological outcome was assessed using measurements of radial inclination, ulnar variance and volar tilt. Of the thirty-seven patients, 13 were male and 24 were female. The mean age was 55.6 years (range 18–87 years). According to the AO classification, there were 8 cases each of C2 and C3 fractures, 6 cases of C1 fractures and 3 cases each of class A2, A3, B1 and B3 fractures. There were 2 patients with class B2 fracture. Results. Post-operatively, the average restoration of volar tilt was 6.47 degrees (range −12.4 to 20.3 degrees). Mean restoration of radial inclination was 23 degrees (range 12.5 to 30.0 degrees). Ulnar variance on average was 0.09 mm (range −5.0–6.7mm). The mean QuickDASH score was 9.8. Conclusion. The results of this study indicate that fixation of displaced intra- and extra-articular distal radial fractures is achieved satisfactorily with restoration of both normal anatomy and function using volar plates

Distal radius fractures have an incidence rate of 17.5% among all fractures. Their treatment in case of comminution, commonly managed by volar locking plates, is still challenging. Variable-angle screw technology could counteract these challenges. Additionally, combined volar and dorsal plate fixation is valuable for treatment of complex fractures at the distal radius. Currently, biomechanical investigation of the competency of supplemental dorsal plating is scant. The aim of this study was to investigate the biomechanical competency of double-plated distal radius fractures in comparison to volar locking plate fixation. Complex intra-articular distal radius fractures AO/OTA 23-C 2.1 and C 3.1 were created by means of osteotomies, simulating dorsal defect with comminution of the lunate facet in 30 artificial radii, assigned to 3 study groups with 10 specimens in each. The styloid process of each radius was separated from the shaft and the other articular fragments. In group 1, the lunate facet was divided to 3 equally-sized fragments. In contrast, the lunate in group 2 was split in a smaller dorsal and a larger volar fragment, whereas in group 3 was divided in 2 equal fragments. Following fracture reduction, each specimen was first instrumented with a volar locking plate and non-destructive quasi-static biomechanical testing under axial loading was performed in specimen's inclination of 40° flexion, 40° extension and 0° neutral position. Mediolateral radiographs were taken under 100 N loads in flexion and extension, as well as under 150 N loads in neutral position. Subsequently, all biomechanical tests were repeated after supplemental dorsal locking plate fixation of all specimens. Based on machine and radiographic data, stiffness and angular displacement between the shaft and lunate facet were determined. Stiffness in neutral position (N/mm) without/with dorsal plating was on average 164.3/166, 158.5/222.5 and 181.5/207.6 in groups 1–3. It increased significantly after supplementary dorsal plating in groups 2 and 3. Predominantly, from biomechanical perspective supplemental dorsal locked plating increases fixation stability of unstable distal radius fractures after volar locked plating. However, its effect depends on the fracture pattern at the distal radius
