Abstract
OBJECTIVE Open reduction and internal fixation (ORIF) is the standard treatment of unstable Colles fracture among the elderly. Modified percutaneous K-wire fixation is becoming increasingly popular in recent years. However, there is controversy concerning its appropriate use. This study aimed to compare the early safety and efficacy of the two different treatments and provide an alternative method for the treatment of unstable Colles fracture among the older population. METHODS Electronic medical records of 60 consecutive unstable Colles fractures patients who underwent surgery from June 2019 to October 2021, by modified percutaneous K-wire fixation (30 patients) or ORIF (30 patients), were reviewed retrospectively. All cases were followed up for 3 months. The outcomes of patients were assessed with operation time, intraoperative blood loss, visual analog score (VAS) for wrist joint pain, palmar tilt (PT), radial inclination (RI), radial height (RH), Gartland-Werley score, total hospitalization costs, hospital stays, postoperative complications, and patient subjective satisfaction. General patient information was also collected. Independent Student's t-test or Mann-Whitney U test were used to compare continuous data. Pearson's chi-square test or Fisher's exact test were used to analyze the categorical data. RESULTS The operation time and intraoperative blood loss were significantly shorter in the K-wire group than in the ORIF group (p < 0.05). Compared with the ORIF group, the VAS of the K-wire group was significantly lower at 1 and 3 days postoperatively (p < 0.05), and no significant differences were observed in VAS between the two groups preoperatively and 7 days postoperatively (p > 0.05). There were no significant differences in the PT, RI, and RH between the two groups preoperatively and at 1, 4, and 8 weeks postoperatively (p > 0.05). Patients in the K-wire group had significantly shorter hospital stays and lower total hospital costs (p < 0.05). All patients were followed up for 3 months, and there was no significant difference in the Gartland-Werley score between the two groups (p > 0.05). Compared with the ORIF group, postoperative complications were lower, and patient subjective satisfaction was higher in the K-wire group, but there were no significant differences (p > 0.05). CONCLUSIONS Modified percutaneous K-wire fixation in the treatment of unstable Colles fracture among the elderly is a safe, effective, rapid, and minimally invasive surgical option for surgeons.

Abstract
INTRODUCTION It is our hypothesis that physician-specific variables affect the management of distal radius (DR) fractures in addition to patient-specific factors. METHODS A prospective cohort study was conducted evaluating treatment differences between Certificate of Additional Qualification hand surgeons (CAQh) and board-certified orthopaedic surgeons who treat patients at level 1 or level 2 trauma centers (non-CAQh). After institutional review board approval, 30 DR fractures were selected and classified (15 AO/OTA type A and B and 15 AO/OTA type C) to create a standardized patient data set. The patient-specific demographics and surgeon's information regarding the volume of DR fractures treated per year, practice setting, and years posttraining were obtained. Statistical analysis was done using chi-square analysis with a postanalysis regression model. RESULTS A notable difference was observed between CAQh and non-CAQh surgeons. Surgeons in practice longer than 10 years or who treat >100 DR fractures/year were more likely to choose surgical intervention and obtain a preoperative CT scan. The two most influential factors in decision making were the patients' age and medical comorbidities, with physician-specific factors being the third most influential in medical decision making. DISCUSSION Physician-specific variables have a notable effect on decision making and are critical for the development of consistent treatment algorithms for DR fractures.

Abstract
Background To report the radiologic outcome and rate of complications of open reduction and internal fixation (ORIF) using a dorsal plate fixation of simple and complex distal radius fractures in adult patients. Methods Patients treated with dorsal ORIF of simple and complex distal radius fractures between December 2008 and April 2013 were included in this single-center retrospective study. Type of fracture, radiographic measurements, and complications were documented. Results One-hundred and sixty-six patients/fractures were included. Restoration of radial inclination (22° ± 3°) was achieved in 38%. Radial height (14 ± 1 mm) was least likely to be restored to normal values postoperative in 25%. Normal ulnar variance (0.7 ± 1.5 mm) could be observed in 60% and adequate volar tilt (11° ± 5°) was achieved in 50% at final follow-up. We observed one loss of reduction in an AO type C2 fracture and a total of 15 nonimplant-related minor clinical complications. Conclusion Our radiographic findings after dorsal plating are comparable to those published on volar plating. The changes in radial height and volar tilt could be attributed to projection-related differences in the radiographs and did not signify a loss of reduction in all cases. Clinical Relevance Dorsal plating of distal radius fractures is safe and remains an important approach in the treatment of complex distal radius fractures. Complications in our study were even less compared to those reported in the literature. Type of Study/Level of Evidence This is a Type IV study. Level of Experience of Surgeons The level of experience of surgeons is III-V.

Abstract
BACKGROUND Radial height is an important prognostic factor in treating distal radius fracture. However, does further collapse of radial height in distal radius fractures after with volar locking plate fixation have a great impact on the prognosis? The present study aimed to elucidate radial height loss and determine the associated risk factors after open reduction and internal fixation with volar locking plate in patients with extra-articular distal radius fractures. HYPOTHESIS Patients with radial height collapse after fracture reduction and internal fixation with a volar locking plate may have poor outcomes. METHODS Data of 87 patients (21 male) undergoing surgery for acute extra-articular distal radius fractures (AO: 23-A2 or 23-A3) between February 2014 and July 2016 were evaluated retrospectively. Patients were divided into two groups by radial height loss. Potential risk factors were tested by Pearson correlation coefficients. Stepwise multiple regression logistic analysis determined significant independent risk factors for extra-articular distal radius fractures. Clinical evaluation was performed by the same surgeon by determining wrist ROM. Grip strength was measured with a Jamar dynamometer and compared with non-affect wrist in percentage. In addition, all the patients were asked to grade modified Mayo wrist score and Visual Analogue Scale (VAS) score. These findings were recorded postoperative 1 year of follow-up. RESULTS Mean radial height loss was 1.3±0.9mm. Age (ß=0.002, p=0.003), postoperative ulnar-positive deformity (ß=0.107, p<0.001), DEXA (ß=-0.015, p=0.008), and shortest diameter of distal fracture fragment in AP and lateral views (ß=-0.050, p=0.037; ß=-0.080, p=0.043) were significantly associated with radial height loss. As for the outcome of clinical prognosis, though radial height collapse group had poorer wrist range of motion, there was no statistical difference. Besides, there were no significant differences in grips strength and VAS score between these two groups. However, in regards of modified Mayo wrist score, the percentage of patients with poor outcomes is significant higher in radial height collapse group (p=0.039). Moreover, all patients with poor outcomes in radial height collapse groups were older than 65-year-old. DISCUSSION Radial height loss is noted in patients undergoing open reduction and internal fixation with volar locking plate for extra-articular distal radius fractures. Risk factors for radial height collapse include advanced age, poor bone quality, shortest distance between fracture site and articular surface and postoperative ulnar-positive deformity. LEVEL OF EVIDENCE IV; non-comparative prospective study.

Abstract
Background: The ideal volar locking plate for the treatment of distal radius fracture should anatomically fit the volar surface of the distal radius. The purpose of this study was to measure the volar cortical angle (VCA) of uninjured adult distal radii to determine how well the VCA matches that of modern volar locking plates and whether variations in the VCA are related to demographic factors. Methods: A retrospective radiographic analysis of 273 uninjured adult distal radii was performed. Patients were stratified into age quintiles: less than 27 years, 27 to 43 years, 44 to 51 years, 52 to 64 years, and 65 years or older. The VCA was measured on lateral wrist radiographs, and patient demographics, including age and sex, were collected. Multivariable linear regression analyses were performed to determine the relationship between VCA and demographic factors. Results: The VCA ranged from 23.2° to 42.6°, with a mean of 32.2° (SD = 3.79). Mean VCA was 32.8 (SD = 4.17) in the youngest cohort (<27 years) and 30.4 (SD = 3.63) in the oldest cohort (>65 years). Mean VCA decreased with age, approximately 0.04° per year after adjusting for sex. Men had a 1.6° greater VCA than women after adjusting for age. Conclusion: Mean VCA was greater than the VCA of modern volar locking plates. The VCA decreased with age in both men and women, and men had a greater VCA than women. Such differences must be taken into account to avoid malreduction, tendon irritation, or intra-articular screw placement using current volar plate designs.

Abstract
PURPOSE OF REVIEW High energy distal radius are commonly multi-fragmentary with significant comminution and/or bone loss. They can also be associated with ligamentous and soft tissue injury and neurovascular compromise. As such, reconstruction of these injuries can be challenging. This paper will review the relevant anatomy, different methods of fixation, and present techniques for difficult fractures. RECENT FINDINGS Volar locked plating is a successful, very common method of treatment for distal radius fractures, but dorsal plating, fragment specific fixation, spanning bridge plating, and external fixation are sometimes necessary, particularly in higher energy injuries characterized by metaphyseal comminution, small volar fragments, intra-articular free fragments or lunate facet subsidence. Extended flexor carpi radialis (FCR), dorsal, and flexor carpi ulnaris (FCU) exposures can assist in visualizing the fracture site. There are many different modes of fixation for distal radius fractures, and successful outcome depends on selection of appropriate fixation based on the fracture pattern and status of the soft tissues.

Abstract
Background Volar locking plating through the flexor carpi radialis is a well-established technique for treating unstable distal radial fractures, with few reported complications. In certain circumstances, including metaphyseal comminuted fractures, bridge plating through a pronator quadratus (PQ)-sparing approach may be required to preserve the soft tissue envelope. This study describes our prospective experience with bridge plating through indirect reduction. Methods Thirty-three wrists (four 23A2, six 23A3, 15 23C1, and eight 23C2) underwent bridge plating through a PQ-sparing approach with indirect reduction from June 2006 to December 2010. Mean patient age was 56.8 years (range, 25–83 years), and the mean follow-up period was 47.5 months (range, 36–84 months). Changes in radiologic parameters (volar tilt, radial inclination, radial length, and ulnar variance) were analyzed, and functional results at final follow-up were evaluated by measuring the Modified Mayo Wrist Score (MMWS) and Modified Gartland-Werley Score (MGWS). Results All wrists achieved bone healing without significant complications after a single operation. At final follow-up, radial length was restored from an average of 3.7 mm to 11.0 mm, as were radial inclination, from 16.4° to 22.5°, and volar tilt, from − 9.1° to 5.5°. However, radial length was overcorrected in three wrists, and two experienced residual dorsal tilt. Excellent and good results on the MGWS were achieved in 30 wrists (90.9%). The average MMWS outcome was 92.6 (range, 75–100). Conclusion Our experience with bridge plating was similar to that previously reported in the earlier publications. Compared with the conventional technique, bridge plating through a PQ-sparing approach may help in managing metaphyseal comminuted fractures of both cortices with a reduced radio-ulnar index.

Abstract
Hardware-related complications are rare in patients with distal radius fractures who were surgically fixed with volar-locking plates. In this report, we present a case of locking screw loosening and migration to the palm four years following the treatment of type 23-C1 distal radius fracture with a volar locking-plate. This complication occurred without evidence of trauma, infection, non-union or plate breakage. Orthopaedic surgeons should be aware of such rare complication and add it to the list of potential postoperative complications when counseling their patients preoperatively.

Abstract
BACKGROUND Internal fixation with plates is a reliable fixation technique for the treatment of distal radius fractures. An ongoing discussion exists whether volar or dorsal plating is the appropriate technique. In clinical practice, volar plate fixation is usually preferred because of the assumed lower complication frequency. However, recent studies with the newer generation low-profile dorsal plates reported lower complication rates. PURPOSE The aim of our study was to evaluate the differences in complication rates between volar and dorsal plate for the treatment of distal radius fractures in adult patients. PATIENTS AND METHODS A total of 214 patients with acute distal radius fractures were included in this retrospective study with a minimum 2 years of follow-up. In total, 123 patients were treated with dorsal plate fixation and 91 patients with volar plate fixation. Our primary study outcome was complication rate. RESULTS The overall risk for complications was 15.4% in the dorsal group and 14.3% in the volar group (p = 0.81). A total of 19 patients had implant removal due to complications: 11 patients in the dorsal group and 8 patients in the volar group (p = 0.97). CONCLUSION There is no preferred plate fixation technique based on these study results. In our opinion, decision for type of plate fixation should be based on fracture type and surgeon's experience with the specific approach and plate types. LEVEL OF EVIDENCE Therapeutic level III.

Abstract
Background Open wedge osteotomy with bone grafting and plate fixation is the standard procedure for the correction of malunited distal radius fractures. Bone grafts are used to increase structural stability and to enhance new bone formation. However, bone grafts are also associated with donor site morbidity, delayed union at bone-graft interfaces, size mismatch between graft and osteotomy defect, and additional operation time. Purpose The goal of this study was to assess bone healing and secondary fracture displacement in the treatment of malunited distal radius fractures without the use of bone grafting. Methods Between January 1993 and December 2013, 132 corrective osteotomies and plate fixations without bone grafting were performed for malunited distal radius fractures. The minimum follow-up time was 12 months. Primary study outcomes were time to complete bone healing and secondary fracture displacement. Preoperative and postoperative radiographs during follow-up were compared with each other, as well as with radiographs of the uninjured side. Results All 132 osteotomies healed. In two cases (1.5%), healing took more than 4 months, but reinterventions were not necessary. No cases of secondary fracture displacement or hardware failure were observed. Significant improvements in all radiographic parameters were shown after corrective osteotomy and plate fixation. Conclusion This study shows that bone grafts are not required for bone healing and prevention of secondary fracture displacement after corrective osteotomy and plate fixation of malunited distal radius fractures. Level of evidence Therapeutic, level IV, case series with no comparison group.

Abstract
Background A Colles’ fracture occurs as a transverse fracture of the metaphyseal region of the distal radius, approximately 25–40 mm proximal to the radio-carpal joint, and is associated with dorsal displacement and angulation of the distal fragment. Other features include radial shortening and palmar tilt. Key radiological measurements usually noted are that of radial length (normally 11 mm), dorsal angulation of the distal radius (normally 10° volar angulation) and radial inclination (normally 22°). A Colles’ fracture is one of the most common types of osteoporotic fractures seen, especially in females above the age of 50. Incidence of men vs. women over the age of 35 was 9/10,000 vs. 37/10,000, respectively. Management Conservative management is commonly an option in stable or minimally displaced fractures which are described as ≤2 mm loss of radial height, ≤5° change in radial inclination and ≤10° of dorsal angulation. This can be managed in a plaster cast for five to six weeks. Furthermore, age of >60 years was found to be the most important factor in predicting whether a reduced unstable fracture would redisplace. Kirschner-wire fixation is a useful and simple operative method to help stabilise fragments that are not severely comminuted. This option was found to be better than plaster cast management alone, but was associated with surgical complications such as infection and nerve injuries. A more common management option utilised for unstable fractures today is open reduction and internal fixation using either dorsal or volar plates. Dorsal plates are less commonly used due to increased risk of volar collapse and tendon rupture with up to a 22% removal of implant rate due to tendon irritation. Volar plates are more popular as they allow a more stable fixation and thus early mobilisation with a better radiological outcome when compared against K-wire fixation. They are also associated with a lower incidence of tendon complications. External fixation management options may either be bridging or nonbridging in regards to the radio-carpal joint. Immobilising the wrist with a bridging external fixation device can be an option when managing a severely comminuted fracture without a large enough distal fragment to secure a distal pin. However, dorsal malunion was six times more likely when compared against a nonbridging option. Though studies showed external fixation devices provided better radiological outcomes when compared to conservative management, there is insufficient evidence to conclude that long-term functional outcomes are also improved. Prevention Often a fracture of this nature is considered as one of the first signs of osteoporosis in a middle-aged adult. Hormone replacement therapies and use of bisphosphonate therapy have been proven to reduce the risk of osteoporotic fractures with alendronate being found to significantly reduce the risk of spine, hip and wrist fractures in postmenopausal women with a mean age of 70 years. Incorporation of other health care professionals such as physiotherapists and occupational therapists is also of vital importance to ensure osteoporotic patients are at a lower risk of sustaining falls.

Abstract
OBJECTIVE To compare the biomechanical stability under load-to-failure conditions of optimally placed fixed-angle volar locking plates versus suboptimally placed variable-angle volar locking plates in unstable, intraarticular distal radius fractures. METHODS A Melone type 1 (AO 23-C3) fracture was created in 25 sawbone radii and plated with either a fixed-angle or variable-angle Synthes plate with identical profile. Four plate positions were tested: distal ulnar (DU, positioned distally to obtain subchondral support and ulnar to hold the lunate facet fragments), distal radial (DR, 3 mm radial to DU), proximal ulnar (PU, 3 mm proximal to DU), and proximal radial (PR, 3 mm proximal and 3 mm radial to DU). The specimens were loaded until failure as defined by a 2-mm displacement of any fracture fragment. The fixed-angle plates were tested in the DU position, whereas the variable-angle plates were tested in all 4 positions. RESULTS The dorsal lunate fragment was the first to fail in every group followed by the radial styloid and volar lunate fragments, respectively. Load-to-failure, from greatest to least, occurred at the DR (278 ± 56 N), PR (277 ± 68 N), DU fixed-angle (277 ± 68 N), DU variable-angle (236 ± 31 N), and PU (202 ± 75 N) positions, respectively. Rigidity was calculated using the slope of the dorsal lunate force-displacement curve before failure (at loads 100-150 N). Rigidity was greatest at the PU position (126 ± 60 N/mm) followed by PR (125 ± 30 N/mm), DU fixed-angle (125 ± 25 N/mm), DR (122 ± 66 N/mm), and DU variable-angle (101 ± 35) positions, respectively. Univariate analysis of rigidity and load-to-failure was not significantly different between groups. CONCLUSIONS In this experimental model, variable-angle screws provided a leeway of 3 mm in both the sagittal and coronal directions without sacrificing construct strength, which may considerably facilitate fixation of these difficult fractures.

Abstract
INTRODUCTION Palmar plate fixation of unstable distal radial fractures is quickly becoming the standard treatment for this common injury. The literature reporting complications consists mainly of isolated case reports or small case series. METHOD Between February 2004 and December 2009 palmar plate fixation was performed in 665 cases. The overall complication rate was 11.3 % (75 complications). Revision surgery was necessary in 10 % (65 procedures). RESULTS The reasons for revision surgery were: postoperative median nerve compression (22 patients) and secondary dislocation (9 patients). An ulna shortening osteotomy for ulnar impingement syndrome was necessary in eight cases. Intraarticular screw placement occurred in three patients. There were two flexor pollicis longus, one finger flexor and three extensor pollicis longus tendon ruptures. Posttraumatic compartment syndrome of the forearm requiring fasciotomy occurred in four cases. There were three cases of infection. Nonoperative treatment was necessary in nine patients, who developed a complex regional pain syndrome. Hardware failure occurred in three cases. Hardware removal was performed in 232 (34 %) cases. CONCLUSION Palmar plate fixation of distal radius fractures is a safe and effective procedure. Nevertheless, complications necessitating a second intervention are relatively common. A proportion of these complications is iatrogenic and can be avoided by improving the surgical technique.

Radiographic outcomes of volar locked plating for distal radius fractures. J Hand Surg Am 2013; 38:40-8.

Abstract
PURPOSE To assess the ability of volar locked plating to achieve and maintain normal radiographic parameters for articular stepoff, volar tilt, radial inclination, ulnar variance, and radial height in distal radius fractures. METHODS We performed a retrospective review of 185 distal radius fractures that underwent volar locked plating with a single plate design over a 5-year period. We reviewed radiographs and recorded measurements for volar tilt, radial inclination, ulnar variance, radial height, and articular stepoff. We used logistic regression to determine the association between return to radiographic standard norms and fracture type. RESULTS At the first and final postoperative follow-up visits, we observed articular congruence less than 2 mm in 92% of fractures at both times. Normal volar tilt (11°) was restored in 46% at the first follow-up and 48% at the final one. Radial inclination (22°) was achieved in 44% at the first follow-up and 43% at the final one, and ulnar variance (01 ± 2 mm) was achieved in 53% at the first follow-up and 53% at the final one. In addition, radial height (14 ± 1mm) was restored in 14% at the first follow-up and 12% at the final one. More complex, intra-articular fractures (AO class B and C and Frykman types 3, 4, 7, and 8) were less likely to be restored to normal radiographic parameters. However, because of the small sample size for some fracture types, it was difficult to discover significant associations between fracture type and radiographic outcome. CONCLUSIONS Volar locked plating for distal radius fractures achieved articular stepoff less than 2 mm in most fractures but only restored and maintained normal radiographic measurements for volar tilt, radial inclination, and ulnar variance in 50% of fractures. The ability of volar locked plating to restore and maintain ulnar variance and volar tilt decreased with more complex intra-articular fracture types. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Background. Dorsally comminuted distal radius fractures are unstable fractures and represent a treatment challenge. The objective of this study was to evaluate the functional and radiological outcome of dorsally comminuted fractures of the distal radius fixed with a volar locking plate. Patients and Methods. Thirty-three consecutive patients with dorsally comminuted fractures of the distal end of the radius were treated by open reduction and internal fixation with AO 2.4 mm (n = 19)/3.5 mm (n = 14) volar locking distal radius plate (Synthes, Switzerland, marketed by Synthes India Pvt. Ltd.). There were 7 type A3, 8 type C2, and 18 type C3 fractures. The patients were followed up at 6 weeks, 3 months, 6 months, and 1 year postoperatively. Subjective assessment was done as per Disabilities Arm, Shoulder, and Hand (DASH) questionnaire. Functional evaluation was done by measuring grip strength and range of motion around the wrist; the radiological determinants were radial angle, radial length, volar angle, and ulnar variance. The final assessment was done as per Demerit point system of Saito. Results. There were 23 males and 10 females with an average age of 44.12 ± 18.63 years (18-61 years). Clinicoradiological consolidation of the fracture was observed in all cases at a mean of 9.6 weeks (range 7-12 weeks). The average final extension was 58.15° ± 7.83°, flexion was 54.62° ± 11.23°, supination was 84.23° ± 6.02°, and pronation was 80.92° ± 5.54°. Demerit point system of Saito yielded excellent results in 79% (n = 26), good in 18% (n = 6), and fair in 3% (n = 1) patients. Three patients had loss of reduction but none of the patients had tendon irritation or ruptures, implant failure, or nonunion at the end of an one-year followup. Conclusion. Volar locking plate fixation for dorsally comminuted distal radius fractures results in good to excellent functional outcomes despite a high incidence of loss of reduction and fracture collapse.

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. LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Background Current surgical approaches to the distal radius include dorsal and palmar plate fixation. While palmar plates have gained widespread popularity, few reports have provided data on long term clinical outcomes in comparison. This paper reports the result of a randomised clinical study comparing dorsal Pi plates and palmar, angle-stable plates for treatment of comminuted, intraarticular fractures of the distal radius over the course of twelve months. Methods 42 patients with unilateral, intraarticular fractures of the distal radius were included and randomised to 2 groups, 22 were treated with a palmar plate, 20 received a dorsal Pi-plate. Results were evaluated after 6 weeks, 3, 6 and 12 months postoperatively focussing on functional recovery as well as radiological results. Results The palmar plate group demonstrated significantly better results regarding range of motion and grip strength over the course of 12 months. While a comparable increase in function was observed in both groups, the better results from the early postoperative period in the palmar plate group prevailed over the whole course. Radiological results showed a significantly increased palmar tilt and carpal sag in dorsal plates, with other radiological parameters being comparable. Pain levels were decreased in dorsal plates after hardware removal and failed to show significant differences after 12 months. However, complications such as tendon ruptures were more frequent in the dorsal plate group. Conclusions Functional advantage of palmar plates gained within the first 6 weeks prevails over the course of a year. Both groups demonstrate further gradual increase of function after 6 months, although dorsal plates did not catch up completely. Improved early postoperative function seems to be the cornerstone for the best possible results. Patients with dorsal plates benefit from hardware removal more than palmar plates in terms of reduction of pain levels. The advantage of palmar plates is a faster functional recovery with lower complication rates. This is especially important in the elderly population. Radiological results did not show a superiority of palmar plates over dorsal plates.

Abstract
BACKGROUND AND PURPOSE Recent literature suggests that the incidence and treatment modalities of distal radius fractures have been changing over the past 2 decades in the developed world. We examined the epidemiology of adult distal radius fractures in Iceland in 2004 and compared it with an Icelandic study from 1985 and other studies. METHODS A retrospective study of the epidemiology, classification, and treatment of distal radius fractures in Reykjavik residents aged 16 and older in 2004 was conducted by analysis of medical records and re-evaluation of all radiographic examinations. RESULTS The 228 fractures included in our material yielded an overall annual incidence of 17/10(4) in men and 37/10(4) in women. Age-specific incidence rose steadily with age in both sexes. One third of the fractures were intraarticular, and working-age men accounted for a large proportion of them. 95% of fractures were treated nonoperatively. INTERPRETATION The annual incidence of distal radius fractures was similar in 1985 and 2004. However, age-specific incidence in younger postmenopausal women decreased sharply. This trend has also been observed in recent Scandinavian studies. Most fractures were treated nonoperatively in Iceland in 2004.

Abstract
BACKGROUND The current options for plate-screw combinations in volar locking distal radius plates used for the treatment of distal radius fractures are either plates with a single distal screw row or plates with multiple distal screw rows. Additionally, the screws themselves may have either fixed angle locking or polyaxial locking mechanisms. To date, there is no evidence or consensus regarding the optimal plate-screw combination. The aim of this study was to assess the biomechanical behaviour of different plate-screw combinations with respect to total distal screw number, number of distal screw rows and screw projection surface area of the most distal row. METHODS Biomechanical study to assess six different plating configurations in five different volar locking plate models in a Sawbone distal radius fracture model. The specimens were loaded with 800 Newton loads for 2.000 cycles at 1 Hz. After cyclic loading, load-to-failure testing was performed. RESULTS With cyclical testing, there was a significant and positive correlation between rigidity and a greater projection area of the most distal screws. Dorsal tilting was significantly more pronounced in plate models with a lesser projection area of the most distal screws and a smaller number of distal screws. With load-to-failure testing, there was a significant increase in rigidity with increasing screw projection area of the most distal row and total number of distal screws. CONCLUSIONS Additional distal screw rows in volar locking distal radius plates might not add substantially to resistance against loss of reduction in the post-operative period.

Abstract
BACKGROUND Optimal surgical management of unstable distal radial fractures is controversial, and evidence from rigorous comparative trials is rare. We compared the functional outcomes of treatment of unstable distal radial fractures with external fixation, a volar plate, or a radial column plate. METHODS Forty-six patients with an injury to a single limb were randomized to be treated with augmented external fixation (twenty-two patients), a locked volar plate (twelve), or a locked radial column plate (twelve). The fracture classifications included Orthopaedic Trauma Association (OTA) types A3, C1, C2, and C3. The patients completed the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire at the time of follow-up. Grip and lateral pinch strength, the ranges of motion of the wrist and forearm, and radiographic parameters were also evaluated. RESULTS At six weeks, the mean DASH score for the patients with a volar plate was significantly better than that for the patients treated with external fixation (p = 0.037) but similar to that for the patients with a radial column plate (p = 0.33). At three months, the patients with a volar plate demonstrated a DASH score that was significantly better than that for both the patients treated with external fixation (p = 0.028) and those with a radial column plate (p = 0.027). By six months and one year, all three groups had DASH scores comparable with those for the normal population. At one year, grip strength was similar among the three groups. The lateral pinch strength of the patients with a volar plate was significantly better than that of the patients with a radial column plate at three months (p = 0.042) and one year (p = 0.036), but no other significant differences in lateral pinch strength were found among the three groups at the other follow-up periods. The range of motion of the wrist did not differ significantly among the groups at any time beginning twelve weeks after the surgery. At one year, the patients with a radial column plate had maintained radial inclination and radial length that were significantly better than these measurements in both the patients treated with external fixation and those with a volar plate (all p < 0.05). CONCLUSIONS Use of a locked volar plate predictably leads to better patient-reported outcomes (DASH scores) in the first three months after fixation. However, at six months and one year, the outcomes of all three techniques evaluated in this study were found to be excellent, with minimal differences among them in terms of strength, motion, and radiographic alignment.

Abstract
The goal of fracture fixation is to achieve bone healing and restore the function of the injured limb in the shortest possible time without compromising safety. Newer technologies such as the locking compression plate (LCP) and its derivatives are valuable additions to the orthopaedic traumatologist's armamentarium. As with any emerging technology, the indications will be extended until a threshold is reached and the limitations of the technology are seen. It is vital that surgeons involved in fracture care are aware of when locked plating is superior to other methods and also when they should use another treatment modality. This paper reviews the use of locked plating as a fixation method. Five topics covered in this review are: a historical perspective on locked plating, general indications, specific modes and techniques, patterns of failure, and an anatomical overview of current indications for locked plating.

Abstract
PURPOSE The goal of this study was to determine whether locking screws or smooth locking pegs optimize fixation of AO C3 intra-articular distal radius fractures. A secondary goal was to determine which combinations of locking screws and smooth locking pegs influence construct stability. METHODS In anatomic radius models, AO C3 intra-articular distal radius fractures were fixed using volar locking plates. For the first part, 16 specimens were randomized to receive either 2 locking screws or 2 smooth locking pegs in each of the 3 pairs of holes in the plate. For the second part, 30 specimens were randomized to receive any 4 combinations of locking screws and smooth locking pegs in each of the 3 pairs of holes. Axial loading to failure was applied. RESULTS Constructs consisting of 4 smooth locking pegs within the lunate fragment were significantly weaker than constructs with 4 locking screws (means 626 N vs 981 N, respectively). Constructs with smooth locking pegs in the ulnar positions of the lunate fragment were weaker than with locking screws in these positions (means 737 N vs 977 N, respectively). Locking screws in the subchondral position of the lunate fragment were stronger than smooth locking pegs in these positions (means 1,227 N vs 934 N, respectively) and any other combination (means 1,227 N vs 942 N, respectively). CONCLUSIONS Use of locking screws as opposed to smooth locking pegs for AO C3 intra-articular distal radius fractures, particularly subchondral and in the ulnar side of the lunate fragment, optimizes construct stability. This may have implications on postoperative rehabilitation protocols and may limit costs related to use of volar locking plates.

Abstract
Kirschner wire (K-wire) fixation is a common technique aimed at treating unstable distal radius fractures. We report our experience with extrafocal K-wire fixation in the treatment of unstable distal radius fractures in 34 patients (AO classification: 10 A2, 5 A3, 14 C1, and 5 C2). The patients' median age was 63 years (range, 16-87 years). K-wires remained in place for a median duration period of 42 days, and a splint was applied during 44 days in median. The median follow-up was 2.5 years (range, 1.3-5 years). At the final follow-up examination, all patients were assessed clinically and bilateral radiographs were taken. The median final range of motion was 69 degrees /64 degrees for extension/flexion, 88 degrees/82 degrees for pronation/supination and 36 degrees/21 degrees for ulnar/radial deviation. Grip strength was 81% of the contralateral side. Using the Gartland-Werley score, 12 patients (35%) had excellent results, 17 (50%) good, and five patients (15%) had fair results. The median final radiographic dorsal tilt was 4.5 degrees (range, 0-14 degrees) and 79% of patients had a loss of volar reduction (median 8 degrees). Radial inclination was in median 20 degrees (range, 10-32 degrees) with 82% of the patients with loss of reduction (median 5 degrees). Radial shortening was in median 0.9 mm (range, -2 to +5 mm) and 62% of patients had median loss of radial length of 1.1mm. Radial shortening was the major source of pain due to ulnar impingement. We found a high complication rate, with 15 patients (44%) suffering from at least one of the 30 reported complications. We did not find any direct correlation between radiographic results and mobility. Although good clinical outcome may be obtained, K-wire fixation cannot be routinely recommended.
