Abstract
Distal radius fractures are increasingly treated by internal fixation, but there have been relatively few studies relating to functional outcome at 12 months or more. The aim of this study was to ascertain the patient reported function of the wrist at a minimum of 12 months following fixation of a distal radius fracture, the time taken to return to work, and the complication rate. We conducted a retrospective review of 187 consecutive patients treated by a specialist hand and wrist trauma team at a tertiary referral unit over a 5 year period. Mean age was 57.3 years (range 16-93). Median time to surgery was 4 days (interquartile range 2-9). Median follow up was 31 months (interquartile range 23-41 months). The median PRWE score was 3; (range 0-83). There was no difference in outcome in patients who had surgery delayed by greater than 2 weeks (p > 0.05). The median time to return to work was 5 weeks (interquartile range 1-8 weeks). There were 15 complications (8 %) including 3 tendon injuries. We have demonstrated an early return to work in patients who were employed, a low complication rate, and highly favourable functional outcomes at a mean of 30 months postoperatively. We recommend the use of the DVR plate and involvement of a dedicated hand and wrist trauma team for treatment of unstable fractures of the distal radius.

Abstract
Approaches to the forearm use internervous planes to allow adequate bone exposure and prevent muscle denervation. The Henry approach utilizes the plane between muscles supplied by the median and radial nerves. The Thompson approach utilizes the plane between muscles supplied by the radial and posterior interosseous nerves. The distal radius may be approached volarly. The extended flexor carpi radialis approach is useful for intraarticular fractures, subacute fractures, and malunions. The distal radius can be approached dorsally by releasing the third dorsal compartment and continuing the dissection subperiosteally. Choice of approach depends on the injury pattern and the need for exposure.

Abstract
PURPOSE To identify whether brachioradialis (BR) release during volar plate fixation for a distal radius fracture affects elbow flexion strength and wrist function. METHODS A total of 42 consecutive patients who were treated by open reduction volar plate fixation for unstable distal radius fractures were enrolled in this study. The BR was not released in 20 of 42 patients (BR preserved group) and was released in 22 patients (BR released group). The primary outcome variable was isokinetic strength and endurance testing of elbow flexion measured by the Cybex isokinetic system 3 months after surgery. Measured at the same time, secondary outcome variables were grip strength, a visual analog scale score for wrist pain, Disabilities of the Arm, Shoulder, and Hand score, and radiographic parameters. We used Mann-Whitney U tests to compare these variables between groups. RESULTS Neither elbow flexion strength and endurance nor any of the secondary outcome variables differed significantly between groups. CONCLUSIONS Release of the BR during a volar approach for a distal radius fracture did not adversely affect elbow flexion strength and wrist function. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic III.

Abstract
BACKGROUND There are relatively few studies in the literature that specifically evaluate accelerated rehabilitation protocols for distal radial fractures treated with open reduction and internal fixation (ORIF). The purpose of this study was to compare the early postoperative outcomes (at zero to twelve weeks postoperatively) of patients enrolled in an accelerated rehabilitation protocol with those of patients enrolled in a standard rehabilitation protocol following ORIF for a distal radial fracture. We hypothesized that patients with accelerated rehabilitation after volar ORIF for a distal radial fracture would have an earlier return to function compared with patients who followed a standard protocol. METHODS From November 2007 to November 2010, eighty-one patients with an unstable distal radial fracture were prospectively randomized to follow either an accelerated or a standard rehabilitation protocol after undergoing ORIF with a volar plate for a distal radial fracture. Both groups began with gentle active range of motion at three to five days postoperatively. At two weeks, the accelerated group initiated wrist/forearm passive range of motion and strengthening exercises, whereas the standard group initiated passive range of motion and strengthening at six weeks postoperatively. Patients were assessed at three to five days, two weeks, three weeks, four weeks, six weeks, eight weeks, twelve weeks, and six months postoperatively. Outcomes included Disabilities of the Arm, Shoulder and Hand (DASH) scores (primary outcome) and measurements of wrist flexion/extension, supination, pronation, grip strength, and palmar pinch. RESULTS The patients in the accelerated group had better mobility, strength, and DASH scores at the early postoperative time points (zero to eight weeks postoperatively) compared with the patients in the standard rehabilitation group. The difference between the groups was both clinically relevant and statistically significant. CONCLUSIONS Patients who follow an accelerated rehabilitation protocol that emphasizes motion immediately postoperatively and initiates strengthening at two weeks after volar ORIF of a distal radial fracture have an earlier return to function than patients who follow a more standard rehabilitation protocol.

Abstract
Background Multiple techniques for corrective osteotomy have been developed in recent years with the same aims: to improve the radiographic parameters and improve motion, pain and grip strength. Volar fixed-angle plates have added a new concept to the treatment of distal radius fractures thanks to the low morbidity of the surgical approach and the strength of the final construct, allowing early mobilization and return to function. Materials and methods Between 2005 and 2012, 20 patients with symptomatic dorsally malunited extra-articular fractures of the distal radius underwent corrective osteotomy using a volar locking plate without additional bone graft. At a mean follow-up of 50 months, all the patients were clinically and functionally evaluated. Results All measurements of pain, final range of motion and grip strength significantly improved compared with preoperative measurements. The mean preoperative DASH score reduced from 54 points preoperatively to 25 postoperatively. Based on the modified Mayo wrist score, we obtained 14 excellent and six good results. Palmar tilt improved from an average of 23° to 11°. Radial inclination improved from an average of 29° to 22°, and ulnar variance decreased from an average of 3.6 mm to 0.9 mm. There were two cases of transient median neuroapraxia that resolved before the 6-week follow-up appointment. No other major complications, including non-union and infection, were observed. Conclusion The volar approach and locking plate, without necessarily the use of bone grafting, proved to be an effective approach for addressing symptomatic and even severe deformities of the distal radius.

Abstract
AIM The aim of the study was to assess how adequately distal radial fracture reduction was reproduced and maintained with the distal volar radius anatomic DVR-A (Biomet, Inc) locking plate. METHODS We looked at a consecutive series of 111 patients treated with the DVR-A plate at our institution from 2007-2010. The preoperative, intra-operative, and postoperative films were reviewed. The AO and Frykman classification was recorded. The sagittal tilt, radial inclination, and radial length were measured on intra-operative X-rays and compared with final follow-up X-rays. The last recorded range of motion at follow-up and a functional assessment using the Disabilities of the Arm, Shoulder, and Hand (DASH) score was recorded. RESULTS At final follow-up a mean radial inclination of 22.22 degrees (11 to 38 degrees), radial height of 11.85 mm (6 to 18 mm), and sagittal tilt of 6.71 degrees volar (-9 to 19 degrees) was achieved. From initial post-operative films, to final follow-up X-rays there was a mean increase of 0.17 degrees in radial inclination, a mean loss of 0.36 mm radial height, and a mean loss of 2.17 degrees volar tilt. The mean extension was 46.8 degrees, flexion 48.3 degrees, pronation 77.4 degrees, supination 74.8 degrees, radial deviation 15.3 degrees and the ulnar deviation 19 degrees. The mean DASH score was 12.8 (0-68). CONCLUSION The DVR-A plate achieved a highly satisfactory reduction of radial length and radial inclination, with a small loss of volar sagittal tilt at final follow-up. A good functional outcome was reported, with a satisfactory range of motion achieved. The DVR-A plate is a safe and effective treatment for unstable and intra-articular displaced distal radius fractures, particularly in younger patients, in the short term.

Abstract
OBJECTIVES Management of AO type B and C fractures of the distal radius is controversial. This study compares outcomes and complications of AO type B and C fractures of the distal radius treated with volar locked plating and nonoperative methods. MATERIALS AND METHODS Sixty-four patients with fractures of the distal radius (AO type B and C) were included in this study, according to inclusion criteria, and were allocated to the volar plating group or nonoperative group by alternate randomization: 32 patients with odd numbers went into the nonoperative group and the other 32 with even numbers went into the volar plating group. Patients in the nonoperative group were managed with closed reduction of the fracture and plaster cast application under an image intensifier. Those in the volar plating group were managed by open reduction and fixation with a volar locked plate. Preoperative and postoperative serial clinico-radiological follow-up was done. The range of movement, grip strength, functional outcome scores and radiological parameters were compared. Student's t-test was used for statistical analysis with significance at p < 0.05. RESULTS Range of movement and functional scores were significantly (p < 0.001) better in the volar plating group, but the difference in ulnar variance and radial and ulnar deviation was insignificant as compared to the nonoperative group. At 24 months follow-up, the nonoperative group had significantly more cases with malunion, articular incongruity and osteoarthritis. CONCLUSION In cases of AO type B or C fractures of the distal radius, volar locked plating provides anatomical stable fixation and early mobilization with better clinico-radiological outcome as compared to conservative treatment.

Abstract
PURPOSE Flexor pollicis longus (FPL) tendon rupture is a well-documented complication related to the use of distal radius volar locking plates (VLPs). The final common pathway of flexor tendon rupture appears to involve implants prominent at the watershed line. We hypothesized that significant differences in VLP prominence exist between various plate designs. METHODS Ten fresh frozen specimens were dissected to identify the path of the FPL in relationship to the distal radius at the watershed line. Five VLP designs were fixed to each specimen based on their anatomic fit, and slid distally until the distal edge of the plate reached the watershed line. The position of each fixed plate was evaluated by fluoroscopy. We used a 3-dimensional laser scanner to create computer models. The total surface area of plate prominence volar to the watershed line and the prominent area beneath the FPL were measured in the axial plane using computer software. RESULTS At the watershed line, the FPL was located at 54% of the maximal width of the radius, as measured from its volar-ulnar corner. There were no significant differences in the location of plate fixation on lateral view radiographs according to the classification of Soong et al. The mean total surface area of plate prominence was 36 mm(2). The mean prominent area beneath the FPL was 10 mm2. Significant differences in plate prominence were noted for various designs. CONCLUSIONS Despite optimal plate placement, various VLP designs were observed to have prominent profiles volar to the watershed line, to varying extents. CLINICAL RELEVANCE The results raise concerns regarding interference between all of the analyzed VLP designs and the FPL. This study may help guide both implant design considerations and assist the surgeon in better understanding implant morphology as it relates to iatrogenic flexor tendon injury.

Abstract
Objectives the purpose of this study was to compare the postoperative radiological and clinical outcomes with minimally invasive percutaneous osteosynthesis using three implants: volar locking plate, intramedullary nail system and nonbridging external fixator for distal radius fractures. Methods forty-eight patients (A group, 16; B group 16; C group 16) underwent minimally invasive percutaneous osteosynthesis of reductible and unstable displaced (Type IIB by Rayhack Classification) distal radius fractures. In B group intramedullary nail system was used, in A group the patients were treated with volar locking plate and in C group the patients were treated by nonbridging external fixator from January 2011 to December 2012. The mean follow-up period was 12 months. Radiologic parameters, range of motion, grip strength, and disability of the arm, shoulder, and hand score were evaluated at each examination (3rd and 6th week, and 12th months). The visual analog scale of wrist pain and complications were assessed at the final follow-up. Results the groups did not differ significantly in radiological outcomes after 12 months, but the clinical results, VAS scale and dash score in group A (volar locking plate) and B (nail intramedullary) were statistically significantly better than that of C group (nonbridging external fixator). One patient underwent an osteosynthesis with nail intramedullary and another with external fixator (C group) developed persistent pain near the site of the superficial radial nerve because of the distal's screw and pins, respectively. Conclusion in clinical parameters, significant differences in outcomes were found between groups A and B after six weeks versus C group.

Abstract
PURPOSE Open reduction and internal fixation of distal radius fractures often necessitates release of the brachioradialis from the radial styloid. However, this common procedure has the potential to decrease elbow flexion strength. To determine the potential morbidity associated with brachioradialis release, we measured the change in elbow torque as a function of incremental release of the brachioradialis insertion footprint. METHODS In 5 upper extremity cadaveric specimens, we systematically released the brachioradialis tendon from the radius and measured the resultant effect on brachioradialis elbow flexion torque. We defined release distance as the distance between the release point and the tip of the radial styloid. RESULTS Brachioradialis elbow flexion torque dropped to 95%, 90%, and 86% of its original value at release distances of 27, 46, and 52 mm, respectively. Importantly, brachioradialis torque remained above 80% of its original value at release distances up to 7 cm. CONCLUSIONS Our data demonstrate that release of the brachioradialis tendon from its insertion has minor effects on its ability to transmit force to the distal radius. CLINICAL RELEVANCE These data imply that release of the distal brachioradialis tendon during distal radius open reduction internal fixation can be performed without meaningful functional consequences to elbow flexion torque. Even at large release distances, overall elbow flexion torque loss after brachioradialis release would be expected to be less than 5% because of the much larger contributions of the biceps and brachialis. Use of the brachioradialis as a tendon transfer donor should not be limited by concerns of elbow flexion loss, and the tendon could be considered as an autograft donor.

Abstract
PURPOSE To evaluate and compare exposures of the radius using 3 surgical approaches. Our hypotheses were that the anterior flexor carpi radialis approach allows greater exposure of the distal radius than does the volar-ulnar approach, and the extensile flexor carpi radialis approach allows comparable proximal and midshaft exposure of the radius compared with the dorsal Thompson approach. METHODS We performed anterior and dorsal exposures of the radius on 10 matched pairs of cadavers (20 forearms) randomly assigned to 1 anterior and 1 dorsal approach. We measured and compared the anatomic features and limits of the anterior flexor carpi radialis approach, volar-ulnar approach to the distal radius, and the dorsal Thompson approach. RESULTS The anterior flexor carpi radialis approach exposed 3.3 cm of distal radius width, was convertible to an extensile approach proximally, required sacrifice of 3 arterial branches, and was limited by the junction of the radial and ulnar arteries. This approach provided 79% of radius exposure and ended 4.7 cm distal to the radiocapitellar joint. The volar-ulnar approach to the distal radius exposed 3.1 cm of distal radius width. The dorsal Thompson approach sacrificed no arterial branches, provided 69% of radius exposure, was limited by the first compartment distally and the posterior interosseous nerve proximally, and ended within 2.6 cm of the radiocapitellar joint. The posterior interosseous nerve coursed 19, 14, and 6 mm dorsolateral to the distal, middle, and proximal margins, respectively, of the supinator insertion on the radius. CONCLUSIONS The volar-ulnar approach provided less access to the radial styloid and was not as extensile as the flexor carpi radialis approach. The Thompson approach provided more proximal exposure than the flexor carpi radialis approach. CLINICAL RELEVANCE Improved knowledge of the anatomy, limits of exposure, and comparison of features between approaches to the radius may facilitate surgical planning and exposure.

Abstract
We analyzed the efficiency of a new plate DiPhos-RM in CFR-PEEK [carbon-fiber-reinforced poly (etheretherketone)] for the volar fixation of distal radius fractures. The new plate's composition has the advantage of x-ray absolute transparency, therefore allowing to monitor the healing of the fracture. The desired combination of high strength and low rigidity is obtained through the use of the polymer composites CFR-PEEK. In this preliminary study (from March 2012 to June 2012), 10 cases of intra-articular distal radius fractures were treated with DiPhos-RM produced by Lima Corporate (Italy). The fractures were classified according to the AO classification, 4 fractures were type C1, 3 type C2, and 3 were A2. A preoperative computed tomography scan was carried out in all patients. One patient also underwent a postoperative computed tomography scan. Grip strength, range of motion, and DASH score were evaluated at follow-up. There were no cases of hardware failure. Specifically, no loss of position or alignment of fixed-angle locking screws or breakage of the plate were observed. Radiographic union was present at an average of 6 weeks (range, 5 to 8 wk). The overall preliminary experience with this new plate is favorable. The new plate is easy to apply and provides the surgeon dual options of fixed-angle or variable-angle screws. It was rigid enough to maintain the reduction also in AO type C articular fractures.

Abstract
The most common complication after distal radius fractures is union with deformity. When symptomatic, distal radial malunions may require operative intervention. Numerous approaches to the distal radius have been described. Most volar approaches involve sectioning the brachioradialis and opening the first extensor compartment to permit adequate exposure. When bone graft is required, this may necessitate a separate incision and further add to the morbidity. We present an alternative anterolateral surgical approach to the distal radius, which allows for excellent exposure, and minimal trauma to the tendons while permitting harvest of local bone graft through the same incision.

Abstract
BACKGROUND Many studies in literature have supported the role of wrist arthroscopy as an adjunct to the stable fixation of unstable intraarticular distal radial fractures. This article focuses on the surgical technique, indications, advantages, and results using wrist arthroscopy to assess articular reduction and evaluates the treatment of carpal ligament injuries and triangular fibrocartilage complex (TFCC) injuries in conjunction with the stable fixation of distal radial fractures. MATERIALS AND METHODS We retrospectively evaluated 27 patients (16 males and 11 females), who underwent stable fixation of intraarticular distal radial fractures with arthroscopic evaluation of the articular reduction and repair of associated carpal injuries. As per the AO classification, they were 9 C 1, 12 C2, 2 C3, 3 B 1, and 1 B2 fractures. The final results were evaluated by modified Mayo wrist scoring system. The average age was 41 years (range: 18-68 years). The average followup was of 26 months (range 24-52 months). RESULTS Five patients needed modification of the reduction and fixation after arthroscopic joint evaluation. Associated ligament lesions found during the wrist arthroscopy were TFCC tears (n=17), scapholunate ligament injury (n=8), and luno-triquetral ligament injury (n=1). Five patients had combined injuries i.e. included TFCC tear, scapholunate and/or lunotriquetral ligament tear. There were 20 excellent, 3 good, and 4 fair results using this score. CONCLUSION The radiocarpal and mid carpal arthroscopy is a useful adjunct to stable fixation of distal radial fractures.

Abstract
INTRODUCTION The purpose of this study was to investigate the radiographic and functional outcome of orthogonal plating (two plates at right angles) via a single volar approach for fixation of intra-articular distal radius fractures with an associated radial column fracture. METHODS In a retrospective, chart-based review, we identified 14 consecutive patients with an intra-articular distal radial fracture who had been treated with locked volar plate fixation and an additional radial column plate. Radial column plates were LCP Distal Radius Plates 2.4; volar plates were LCP Distal Radius Plates 2.4 (n=13) or LCP T-plate (n=1). These patients were operated on using the extended volar flexor carpi radialis (FCR) approach as described by Orbay. Radiographic measurements, healing rates, time to union, complications, range of motion, the Gartland and Werley score, and the QuickDASH questionnaire were done in order to evaluate the radiographic and functional outcomes of this technique. RESULTS Thirteen of the 14 fractures healed within 7 weeks after surgery. Two implant removals were done. One patient had malposition of the fracture and carpal tunnel symptoms, which required a second surgery. No other complications (e.g., first dorsal compartment problems, radial plate prominence problems and radial sensory nerve problems) were observed. The average length of follow-up was 30 months (range, 12.8 months to 5.4 years). Radiographic results after healing were radial inclination 20°, radial length 11.4mm, tilt 6° volar, ulnar variance -0.5mm, articular gap 0.1mm and step-off 0.1mm. Wrist range of motion was flexion-extension arc 93°, ulnar-radial deviation arc 49° and pronation-supination arc 152°. Nine patients scored 'excellent' on the Gartland and Werley score, while the remaining five patients scored 'good'. The average QuickDASH score was 13.4. CONCLUSION Additional fixation of a radial column process in an intra-articular distal radius fracture via the extended FCR approach using a standard volar plate and radial LCP resulted in good/excellent radiographic and functional outcome.

Abstract
PURPOSE The aim of the study is to evaluate the safety and utility of the extended flexor carpi radialis (FCR) exposure and volar locking plate fixation for partially healed malaligned fractures of distal radius. MATERIALS AND METHODS Thirty-five patients with a partially healed malaligned fracture of the distal radius had realignment of the fracture using an extended FCR approach (release of the insertion of the brachioradialis and dorsal periosteum) and volar locked plate and screw fixation. RESULTS Retrospective review an average of 20 months after the index operation patients identified an average wrist extension of 68°, flexion of 64°, pronation of 84° and supination of 85°. Radial inclination, volar tilt and ulnar variance significantly improved compared to preoperative radiographs. All fractures healed, and there were no infections, implant loosening or breakage or tendon ruptures. CONCLUSIONS This study demonstrated that the extended FCR approach is safe and effective as a treatment method for nascent malunions of the distal radius.

Abstract
Numerous methods of treatment are available for the management of distal radius fractures, with modern trends favoring volar fixed-angle distal radius plates. Whatever the method of fixation, recognition, management, and prevention of the known associated complications are essential to achieve a good outcome. This article reviews the common preventable complications that are associated with operative treatment of distal radius fractures, including tendon injuries, inadequate reduction, subsidence or collapse, intra-articular placement of pegs or screws, nerve injuries, complex regional pain syndrome, carpal tunnel syndrome, and compartment syndrome.

Abstract
INTRODUCTION Fractures of the distal radius are common upper limb injuries, representing a substantial proportion of the trauma workload in orthopaedic units. With ever increasing advancements in implant technology, operative intervention is becoming more frequent. As growing numbers of surgeons are performing operative fixation of distal radial fractures, an accurate understanding of the relevant surgical anatomy is paramount. The flexor carpi radialis (FCR) tendon forms the cornerstone of the Henry approach to the volar cortex of the distal radius. A number of key neurovascular structures around the wrist are potentially at risk during this approach, especially when the FCR is mobilised and placed under retractors. METHODS In order to clarify the safe margins of the FCR approach, ten fresh frozen human cadaver limbs were dissected. The location of the radial artery, the median nerve, the palmar cutaneous branch of the median nerve and the superficial branch nerve were measured with respect to the FCR tendon. Measurements were taken on a centre-to-centre basis in the coronal plane at the watershed level. In addition, the distances between the tendons of brachioradialis, abductor pollicis longus and flexor pollicis longus, and the radial artery and median nerve were measured to create a complete picture of the anatomy of the FCR approach to the distal radius. RESULTS The structure most at risk was the palmar cutaneous branch of the median nerve. It was located on average 3.4mm from the FCR tendon. The radial artery and the main trunk of the median nerve were located 7.8mm and 8.9mm from the tendon. The superficial branch of the radial nerve was 24.4mm from the FCR tendon and 11.1mm from the brachioradialis tendon. CONCLUSIONS Operative intervention is not without complication. We believe a more accurate understanding of the surgical anatomy is key to the prevention of neurovascular damage arising from the surgical management of distal radial fractures.

Abstract
Distal radial physis closure in children can develop severe wrist deformity (radial shortening). These patients can be treated using a single-step surgery. It was carried out in the form of a corrective osteotomy adopting the volar approach, with fixed-angle volar plate fixation and bone grafting from the iliac crest. There have been few descriptions of the use of this technique in the management of deformities related to early epiphysiodesis in distal radius. The use of fixation systems for the radius, using fixed-angle locking plates, allows radius lengthening adjusted to demand after osteotomy, using the combination of the plate and distal locking pins as spacer-with custom-sized tricortical iliac crest grafting within the defect. The freeing of soft parts such as the dorsal periosteum and brachioradialis muscle tendon allows adequate bone lengthening in a single-surgical step.

Abstract
Articular comminuted distal radius fractures are still a surgical challenge. The development of volar locking plate device allows a stable and anatomic restoration of the distal radius. We propose a modification of the classic anterior approach for articular fracture of the distal radius with ulnar impaction. By a single incision, we realize 2 windows to expose the medial and lateral column of the distal radius. This technique is indicated for complex articular distal radius fractures associated with an ulnar comminution. The dissection is extended superficially to the ulnar side of the carpal tunnel elements by a blunt dissection of the anterior part of the wrist between the skin and the superficial layer of the flexor carpi radialis, in subcutaneous tissues and the antebrachial fascia to preserve the sensitive branch of the median nerve. This new approach allows reduction of each fragment of a comminutive articular fracture without exposing the flexor tendon and median nerve to excessive tension. In our surgical armatorium, we reserved this technique for distal radius fractures with articular ulnar damage because of the possible risk to the median cutaneus branch.

Abstract
INTRODUCTION Volar locking plates have revolutionised the treatment of distal radius fractures but complications are not uncommon. We present a cadaveric study and a technical tip to assist in the accurate and reproducible placement of one such plate. STUDY We placed 25-g needles in the distal radioulnar joint and radiocarpal joint and measured the distance from these needles to a DVR plate in its optimal position. This distance measured 5mm, corresponding to the width of the depth gauge handle. Placing this next to needles in these joints can help pre-plan the most distal and ulnar extent of the plate allowing for reproducible optimal positioning of the DVR plate. TECHNIQUE The technique developed uses the existing kit and is simple and easy to build into one's existing fixation technique.

Abstract
INTRODUCTION The purpose of this study was to determine whether a displaced dorsal rim fracture has an adverse effect on wrist function after volar plate fixation of a dorsally displaced distal radius fracture (DRF). MATERIALS AND METHODS Two matched cohorts of 23 matched patients, one with a displaced dorsal rim fracture >2mm (group 1), and the other without a dorsal rim fracture (group 2) were analysed in this study of volar locking plate fixation for dorsally unstable DRFs. The two cohorts were analysed for differences in wrist function and wrist pain, radiographic parameters and arthritic grades of radiocarpal joints. Displacement of dorsal rim fragments and diameters of the retained articular portions of dorsal rims in group 1 were measured. RESULTS No significant difference was found between the two groups in overall wrist function or wrist pain. Mean displacement of dorsal rims in group 1 was 3.0mm and the mean diameter of the retained articular portion of dorsal articular wall was 2.0mm. No significant difference was found between the two groups in terms of any radiographic parameters or the arthritic grading of radiocarpal joints. CONCLUSION A displaced dorsal rim fracture does not appear to affect outcomes adversely after volar locking plate fixation of dorsally displaced DRFs.

Abstract
The aim of this investigation was to evaluate the efficiency of fixed angle plates DVR in the treatment of C1 and C2 type articular wrist fractures according to the AO classification. From July 2005 to March 2009, 40 wrist fractures were treated: 18 were of C1 type while 22 of C2 type according to AO classification. The age of patients varied from 25 to 79 years old. The average length of follow-up was 17 months (range, 4-37 months). The average articular motility was flexion 59.4° and extension 62.7°. Final radiographic parameters were of 18.7° of average ulnar inclination, 10.3° of average dorsal inclination, and 1.45 mm of negative ulnar variance. All patients were reassessed according to Mayo Modified Wrist Score getting a very good/good result in 82% of cases and a medium/poor one in 18%. The DASH score pulled off 46.3 points in the first group, 5.1 in the second group, and 6 in the third one. The statistical analysis based on Student's t test showed how C1 and C2 classification did not influence the results using the same treatment. DVR plate showed a very good reliability and a sufficient stability with both C1 and C2 fractures.

Abstract
The forearm contains many muscles, nerves, and vascular structures that change position on forearm rotation. Exposure of the radial shaft is best achieved with the Henry (volar) or Thompson (dorsal) approach. The volar flexor carpi radialis approaches are used increasingly for exposure of the distal radius. Although the dorsal approach is a safe utilitarian option with many applications, its use for managing fracture of the distal radius has waned. Potential complications associated with radial exposure include injury to the superficial branch of the radial nerve, the lateral antebrachial cutaneous nerve, and the cephalic vein. Dorsal and ulnar proximal radial exposures are associated with increased risk of injury to the posterior interosseous nerve. With surgical exposure of the ulna, care is required to avoid injuring the dorsal cutaneous branch of the ulnar nerve.

Abstract
INTRODUCTION Fractures of the distal radius are among the most common fractures seen. They encompass a myriad of presentations and fracture patterns that often benefit from various open reduction and internal fixation techniques-including volar plating, dorsal plating, radial plating, intramedullary nailing, and fragment-specific fixation. In order to obtain optimal reduction of these fractures, surgeons require a thorough understanding of the anatomy and various surgical exposures. ANATOMY The distal radius is surrounded by a soft tissue envelope rich in vascularity and cutaneous innervation. The osseous surface consists of two articular surfaces and three cortical sides covered almost entirely by soft tissue. SURGICAL APPROACHES Approaches to the distal radius can be broadly divided into volar, radial, and dorsal. Visualization of the articular surface can be accomplished best arthroscopically. Arthroscopy can be performed alone or in conjunction with other open approaches to the distal radius. SUMMARY This article will review the pertinent anatomy and various surgical approaches in order to facilitate the surgeon's ability to safely expose a distal radius fracture.

Abstract
Upper extremity injuries are more prevalent in obese people than in nonobese people after low-energy falls. Because splinting and casting are inefficient methods of stabilization in the setting of obesity, internal fixation provides stability for mobilization and realignment. Morbid obesity adversely affects positioning, surgical exposures, and complications associated with operative fixation. Avoiding short cuts and complications, morbidly obese patients should be able to return to normal functioning.

Abstract
PURPOSE Few studies have investigated the effectiveness of early postoperative pain control regimens after volar plating for distal radius fractures. This study evaluated postoperative levels of pain after volar plating of distal radius fractures under axillary nerve block in patients with and without injections of local anesthetics, narcotics, and epinephrine around the fracture site. METHODS Perioperative pain levels were prospectively assessed in 44 consecutive patients who had had volar plating for a distal radius fracture under axillary nerve block at a mean time of 2.8 days after trauma. Intravenous, patient-controlled analgesia and prescheduled analgesic medications were administered to all patients. In addition, patients were randomly allocated to 2 groups: perifracture site injection (PI; n = 22) and no perifracture site injection (no-PI; n = 22). At the end of surgery, PI group patients were administered perifracture site injections and blocks of the superficial radial and interosseous nerves with a local anesthetic mixture consisting of ropivacaine, morphine, and epinephrine. During the first 48 hours after surgery, pain visual analog scale (VAS) scores (0 to 100), total amount of narcotic consumption, incidences of additional narcotic requirement, and opioid-related side effects were assessed. RESULTS The overall mean pain VAS scores among all 44 study subjects were 29 before surgery, and 58, 47, 40, and 27 at 4, 8, 24, and 48 hours after surgery, respectively. Thirteen patients needed additional pain rescue despite the multimodal analgesic approach used. No intergroup differences were observed between the PI and no-PI groups in terms of VAS pain scores, total narcotic consumption, adjuvant pain rescue incidence, and opioid-related side effects. CONCLUSIONS Postoperative mean pain VAS scores after volar plating of distal radius fractures were found to be 58 at 4 hours and 47 at 8 hours. Perifracture site injections were not found to provide any additional pain control benefit. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic II.

Abstract
INTRODUCTION Fractures of the distal radius are one the commonest orthopaedic injuries. Recent advances in implant technology have seen a dramatic rise in the number of fractures treated with volar locked plates, as they permit accurate peri-articular reconstruction. The surgical approach along the bed of flexor carpii radialis (FCR) tendon encounters a number of key soft tissue and neurovascular structures during the dissection to the fracture plane. The aim of this study was to describe the exact position of such structures involved (and hence at risk) during the FCR approach. METHODS 100 adult MRI scans were reviewed. The relationships between the brachioradialis tendon (BR), flexor carpi radialis (FCR) tendon, flexor pollicis longus (FPL) tendon, median nerve (MN) and radial artery (RA) were measured. RESULTS The male to female ratio was 35:65. Average age was 39. FCR tendon was 7.4 mm (SD 1.46) from the RA and 7.01 mm (SD 2.37) from the MN. The distance between BR and RA was significantly different between male and female (5.06 mm vs. 4.1 mm, p=0.034). CONCLUSION This study highlights the precise nature of the surgical anatomy involved in dissection to the fracture site. Vigilance is needed during the initial steps of the FCR-bed approach to avoid damage to the radial artery and median nerve which lie in close proximity. If the approach is extended to include a brachioradialis tenotomy, we suggest this should be made under direct vision, given its relationship with the radial artery.

Abstract
INTRODUCTION The results and complications using a palmar plate system with the possibility of multidirectional fixed-angle screw fixation (Aptus® Radius 2.5 mm by Medartis®) for the treatment of unstable distal radius fractures were evaluated in a single cohort study including 62 patients. PATIENTS Patients with extra- and intraarticular fractures were evaluated separately. The mean follow-up was 14.7 months. Active wrist motion averaged 60.1° extension, 52.0° flexion, 86.3° pronation, and 84.6° supination. Grip strength averaged 89% of the contralateral wrist. RESULTS There was no loss of the initial reduction with bony union in all cases. The mean DASH-score was 12.6 points. Postoperative complications included two extensor pollicis longus tendon ruptures, two median nerve compression syndromes, one complex regional pain syndrome, and one postoperative haematoma. In our series the results of the intraarticular fracture group were similar to the extraarticular fracture group. The complication rate, however, was substantially higher in the intraarticular fracture group. CONCLUSION We conclude that palmar plating with multidirectional fixed-angle screw insertion is an effective and useful treatment option, especially for complex intraarticular distal radius fractures.

Abstract
PURPOSE To evaluate the safety and efficacy of a hybrid flexor carpi radialis (FCR) approach for volar plate osteosynthesis of displaced distal radius fractures with concurrent prophylactic carpal tunnel release (CTR) in patients without preoperative signs or symptoms of acute carpal tunnel syndrome secondary to the fracture. METHODS A total of 68 displaced distal radius fractures in 65 eligible adult patients (35 men, 30 women; mean age, 48.6 +/- 15.4 y) who had volar plate osteosynthesis and concomitant prophylactic CTR through a hybrid FCR approach by a single surgeon were included in this study. A systematic chart review and subsequent telephone questionnaire were performed to identify any postoperative median nerve dysfunction, recurrent motor or palmar cutaneous branch injury, tendon injury, or other complications directly related to the approach. RESULTS Reported symptoms consistent with late median nerve dysfunction were identified in 2 cases; however, no patients in this series required additional surgery for early or late median neuropathy. Furthermore, no cases of median nerve sensory or motor branch injury or tendon injury were identified. No other unforeseen complications specifically related to the approach were observed. CONCLUSIONS Volar plate osteosynthesis of distal radius fractures with a concurrent prophylactic CTR can be safely performed through the described hybrid FCR approach in patients without signs or symptoms of acute CTS. Routine release of the transverse carpal ligament with the hybrid FCR approach at the time of fracture fixation might reduce the incidence of postoperative median nerve dysfunction. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
BACKGROUND Though, volar fixed-angle plating has become increasingly popular to treat distal radius fractures no studies are available comparing the mechanical properties of different screw configurations to fix the plate to the shaft. The aim of the present study was to evaluate the effect of an additional locking screw directly proximal to the fracture site and to assess if such a screw might be protective against secondary loss of reduction after volar fixed-angle plating. METHODS Ten Sawbones radii were used to simulate an extra-articular distal radius fracture model (AO/OTA 23-A3). In the first group (n = 5), volar fixed-angle plates (Aptus Radius 2.5, Medartis, Switzerland) were fixed to the radius shaft with a single nonlocking cortex screw in the oval hole and with two locking screws in the holes proximal to the long hole (LLNx); in the second group, the plates were fixed identically as in the first group, but an additional locking screw was inserted into the plate-hole distal to the oval hole, proximal to the fracture site (LLNL). After embedding, specimens were tested with a servohydaulic material testing machine under cyclic axial loading with 800 N for 2,000 cycles. Axial stiffness, elastic axial deformation (elastic dorsal tilt angle), and plastic deformation (plastic dorsal tilt angle) were recorded. RESULTS After 2,000 cycles, stiffness was 761.6 (+/-59.5) N/mm in group LLNx and 628.9 (+/-37.6) N/mm in group LLNL without significant difference. Elastic deformation and elastic tilt angle were 1.05 (+/-0.08) mm and 3.9 (+/-0.3) degree in group LLNx. In group LLNL, elastic deformation and elastic tilt angle were 1.27 (+/-0.08) mm and 4.7 (+/-0.3) degree, respectively. Plastic deformation and plastic tilt angle were significantly higher in group LLNx (p < 0.001). After 2,000 cycles, dorsal tilt angle was 1.9 (+/-0.3) degree in group LLNx and 0.7 (+/-1.0) in group LLNL. CONCLUSION This study showed the mechanical superiority of volar fixed-angle plates with a "protection screw" in an extra-articular fracture model. Further clinical investigation is needed to verify the results.

Abstract
Five different palmar fixation plate designs were compared in a distal radial osteotomy cadaver model with regard to their biomechanical properties. A metaphyseal osteotomy gap of 1 cm was performed and the osteosynthesis was plated according to the manufacturer's instructions. Axial load was applied to the construct by a pneumatic material testing machine. Five implant groups with eight cadavers each were tested concerning stiffness. None of the constructs developed deformity and movement of the fracture gap larger than 2 mm with a load of 100 N. Increasing the load to 250 N revealed significant differences in stiffness and failure load between the different plates. The mean stiffness under axial load (mean+/-standard deviation) was 356.4+/- 138.6 N/mm for the radius correction plate without lateral tongue, 299.7+/-86.3 N/mm for the radius correction plate with lateral tongue, 132.8+/-41.5 N/mm for the distal volar radius plate, 112.5+/-40.2 N/mm for the 3.5 mm titanium locking compression plate and 91.9+/-29.2 N/mm for the standard stainless steel 3.5 mm T-Plate. The non-angular stable implant (STP plate) had the lowest stiffness. Unexpectedly, there were differences over 100% concerning the stiffness between the at first glance nearly similar angular stable implants. Additionally, a review of the literature concerning biomechanical investigations of the distal radial fracture was performed.

Abstract
Complex fractures of the distal radius are articular lesions and comminuted at the level of the epiphysis and metaphysis. Their treatment is difficult and in most cases surgical. Of all the different osteosynthesis methods available, internal fixation with plate and screws is the most commonly used. In particular, angular stability plates are superior in terms of rigidity and stability to conventional volar and dorsal plates. DVR plate has these mechanical characteristics, and its low profile has reduced frictions with surrounding soft tissues. For these reasons, this device implanted through a single volar approach, can stabilize the majority of volarly and dorsally displaced unstable distal radius fractures. In this study, 48 patients, affected by complex fractures of the distal radius treated with DVR volar plates, were assessed by the Mayo modified wrist score, the Italian version of the disability of the arm, shoulder and hand. The satisfactory results observed confirm the efficacy of this device.

Abstract
The recent development of locking-plate technology has led to a potential revolution in the management of fractures of the distal radius. This review examines the evidence for pursuing anatomical restoration of the distal radius and the possible advantages and pitfalls of using volar locking plates to achieve this goal. The available evidence for adopting volar locking plates is presented and a number of important and, as yet unanswered, questions are highlighted.

Abstract
Dorsally angulated malunions of the distal radius have historically been corrected with an opening wedge osteotomy fixed with a dorsal plate. Volar locking plates may facilitate a less morbid approach to corrective osteotomies of the wrist. Eight consecutive patients with an average age of 40 years (range, 15-52 years) underwent correction of a distal radius deformity through a volar approach. Clinical follow-up averaged 17.4 months (range, 7-41 months). Preoperative radiographs revealed an average of 24 degrees of dorsal tilt in patients with dorsal deformity. Postoperatively, their average measurement was <3 degrees of volar tilt. Patients were initially ulnar-positive with an average of 4 mm ulnar-positive variance (range, 2-7 mm). This corrected to less than 1 mm postoperatively. Postoperative disabilities of the arm, shoulder, and hand (DASH), SF-12, and Mayo Wrist scores averaged 10.8, 40.5, and 82.5, respectively. There were no nonunions, and no plates required removal. Distal radius deformity can be effectively addressed through a volar approach with the use of a locking plate.

Abstract
Although extensor pollicis longus tendon ruptures have been noted as a complication of distal radius fractures, flexor tendon ruptures in association with acute fractures of the distal radius are rare. We report a rupture of the flexor carpi radialis tendon as a complication of an acute distal radius fracture that was discovered during operative management of the fracture.

Abstract
The fracture management principles of anatomic or near anatomic reduction, fracture stabilization, minimal operative trauma, and early joint motion are paramount in man-aging unstable distal radial fractures. The operative approach and plate selection should correlate with the fracture configuration. Plates have the advantages of providing secure fixation throughout the entire healing process without protruding wires or pins and allowing early and intensive forearm, wrist, and digital exercises. Disadvantages include additional operative trauma, including fragment devascularization; some additional risk of wrist stiffness; occasional tendon rupture; and at times, the need for plate removal. New developments in plate and screw design and operative strategies, fragment specific fixation, and plate strength have improved results with plate fixation. Fixed angle blades and locking screws and pegs enhance overall plate stability, support the articular surface of the distal radius, and are effective in fractures occurring in osteopenic bone.

Abstract
PURPOSE The purpose of this study was to compare the outcomes of 2 treatments for unstable distal radius fractures: open reduction internal fixation (ORIF) through a volar approach with a fixed-angle implant and a standard external fixation (EF) method. METHODS This study included patients with comminuted unstable intra-articular and extra-articular distal radius fractures treated by a single surgeon. Data were gathered retrospectively on 11 patients treated with EF who had been followed up for an average of 47 months (range, 12-84 mo). Prospective data were gathered on 21 patients who were treated with ORIF through a volar approach with a fixed-angle implant. Follow-up evaluation for this group averaged 17 months (range, 12-24 mo). The 2 groups were compared for range of motion (ROM), strength, and functional outcome as measured by the Patient Rated Wrist Evaluation (PRWE) and the Disability of the Arm, Shoulder, and Hand Questionnaire (DASH). Fracture reduction was evaluated from radiographs taken at the last follow-up visit and compared between groups. RESULTS The mean passive wrist ROM at the final follow-up evaluation in EF patients was 59 degrees extension and 57 degrees flexion, compared with 63 degrees extension and 64 degrees flexion in patients treated with ORIF. Passive pronation/supination arc of motion was similar for the 2 groups, as were the DASH and PRWE scores. Grip strength as a percentage of the opposite wrist was significantly greater in the external fixation group, a possible consequence of longer follow-up evaluation. Final radiographic measurements for the EF group averaged 5 degrees volar tilt and 25 degrees radial inclination, with 2.2-mm ulnar-positive variance. The ORIF with volar plating group averaged 10 degrees volar tilt and 22 degrees radial inclination, with .5-mm ulnar-negative variance. Radial length and volar tilt were significantly greater for the ORIF group. The average final intra-articular step-off was significantly different, with 1.4-mm step-off in the EF group and .4 mm in the ORIF group. CONCLUSIONS The use of ORIF with a volar fixed-angle implant resulted in stable fixation of the distal articular fragments, allowing early postsurgical wrist motion. The PRWE and DASH scores for the groups were equivalent, whereas intra-articular step-off, volar tilt, and radial length were better in the ORIF group. There were few complications, implant removal was not necessary, and early postsurgical wrist ROM was initiated without loss of reduction.
