Effect of Screw Length in Volar Plating for Intra-articular Distal Radius Fractures: A Biomechanical Study

PurposeThe purpose of this study was to compare the effect of varying screw lengths on load to failure and retention of the dorsal ulnar corner fragment after fixation of comminuted intra-articular distal radius fractures in a cadaveric model. MethodsTwenty-four fresh frozen cadaveric forearms were subjected to a standardized distal radius osteotomy to mimic an intra-articular fracture pattern. Dual X-ray absorptiometry scans were performed to ensure minimal variability in bone density. All fractures were fixed with a volar locking plate and distal locking screws. Three different lengths of distal locking screws were used in each group of eight specimens to simulate the clinical decision of different distal screw lengths. The screw lengths tested were bicortical, 100% of the width of the bone but unicortical, and 75% of the width of the bone and unicortical. All specimens were preconditioned with cyclic axial loading and then axially loaded using matching acrylic resin molds to clinical failure and fragment displacement as detected by a motion analysis system. Retention or loss of the dorsal ulnar corner fragment during loading was recorded as a binary variable. ResultsBetween the three groups, there were no statistically significant differences in precycling stiffness, postcycling stiffness, load at 2 mm displacement of the dorsal ulnar corner, or force at failure. The group with 75% length screws had a significantly higher loss of reduction of the dorsal ulnar corner (86%) compared with the other groups (0%). ConclusionsVarying screw lengths did not affect the stiffness or overall loads to failure of axially loaded specimens. However, the 75% length screws did not reliably secure the dorsal ulnar corner fragments. Although this did not significantly affect the overall load to failure of the construct, displacement of this fragment may have implications for rotation of the forearm through the distal radioulnar joint. Clinical relevanceSurgeons should consider the utilization of full-length unicortical locking screws to ensure adequate fixation of the dorsal ulnar corner.

Functional Outcome of Intra-Articular Distal End Radius Fracture Treated Surgically by Volar Locking Plate: A Prospective Study

Background. Unstable distal end intra-articular fractures of the radius pose a greater risk of reduction loss, potentially resulting in malunion and poor functional outcomes. Therefore, the amount of reduction and the technique of fracture fixation play a crucial role in achieving improved functional outcomes and ensuring patient satisfaction.Material and methods. This is a study of prospectively enrolled 27 patients with displaced intra-articular distal end radius fractures treated surgically by volar locking plate through modified Henry’s approach in the department of orthopedics at a tertiary care center. Patients were post-operatively evaluated for functional outcome and complications. Results. Out of the 27 patients 26 came for regular follow up, ranging from 3 months to 18 months and one patient was lost to follow-up. The functional outcome was investigated with the Mayo wrist score. Excellent scores were noted in 34.6%, good in 53.8% and satisfactory in 11.5% of the patients. Conclusion. Irrespective of the direction and degree of displacement, the volar locking plate as a treatment for an intraarticular distal end radius fracture is a good option as it provides stable fixation, and good to excellent outcomes with less complications.

Intra-articular fracture reduction: a comparative observational study of clinical results after the surgical treatment of distal radius fractures

Purpose: This study compared the outcomes of intra-articular fracture reduction for distal radius fractures. Methods: Among 180 patients who underwent open reduction and plate fixation, the exclusion criteria were as follows: non-acute fracture (>1 month), an accompanying ulnar neck fracture, a distal ulnar fracture requiring fixation, fixation through the dorsal approach, other accompanying hand fractures, the absence of preoperative or postoperative computed tomography (CT), and follow-up for <1 year. Intra-articular fractures were evaluated through CT. Forty-eight patients with intra-articular fractures were studied. Displaced intra-articular fractures were defined as: (1) articular step-off ≥1 mm, (2) fracture gap ≥2 mm, or (3) gross incongruence. Reduction was classified as good (n=23) or poor (n=25) based on postoperative CT. The pain visual analogue scale (pVAS), the quick Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and range of motion of the wrist joint were compared between both groups.Results: No significant between-group differences were found in the preoperative demographic data and the postoperative pVAS and quick DASH scores (pVAS: 0.6 vs. 0.8 and quick DASH: 9.4 vs. 10.2 in the good vs. poor reduction groups, respectively). However, the flexion-extension arc was significantly restricted in the poor reduction group (162° in the good reduction group vs. 146° in the poor reduction group, p<0.001).Conclusion: The reduction of the articular surface was not related to pain and functional results at the mid-term follow-up after the surgical treatment of intra-articular distal radius fractures. However, insufficient fracture reduction affected the postoperative range of motion.

What Have We Learned in the Wrist Joint of Distal Radius Fracture through Wrist Arthroscopy?

Abstract Background Wrist arthroscopy is an efficient tool for the surgical treatment of distal radius fracture (DRF). It could show us the various conditions of the radiocarpal joint, its effectiveness seems to overwhelm that of fluoroscopy. Methods Since July 2005, we have performed wrist arthroscopy and plate presetting arthroscopic reduction technique (PART) for 141 extra-articular and 559 intra-articular DRFs and investigated various kinds of intra-articular conditions and advantages of wrist arthroscopy. Results The pathological conditions clarified and the advantages of PART in the surgical treatment of DRF are: (1) accurate reduction of intra-articular fragments is possible compared with fluoroscopic reduction, (2) intra-articular fragments (free body) undetected with radiograph and CT can be recognized, (3) screw protrusion into joint surface can be monitored, (4) intra-articular soft tissue injury associated with fracture can be evaluated and treated, and (5) debridement of joint hematoma can be performed. Severe complications such as tendon rupture, major neurovascular injury or compartment syndrome from arthroscopy were never encountered. Conclusions The volar locking plate fixation and simultaneous arthroscopic intervention is problematic because vertical traction must be applied and released during surgery. PART can overcome these difficulties and achieved good clinical results.

Functional and Radiological Outcomes Following Arthroscopic-Assisted Reduction and Fixation of Intra-Articular Distal Radius Fractures

Abstract Background: Intra-articular distal radius fractures (DRFs) are prevalent injuries that are usually difficult to treat and rehabilitate. These injuries may be associated with ligamentous injuries or intra-articular loose fragments. This study aims to assess the functional and radiological results of using arthroscopic-assisted reduction and fixation, which offers direct visualization of the joint surface, evaluation of intra-articular ligaments, and removal of loose fragments, potentially enhancing recovery outcomes. Patients and Methods: This quasi-experimental interventional study evaluated the functional and radiological outcomes of arthroscopic-assisted reduction and fixation for intra-articular DRFs. The study included 26 patients who met specific inclusion criteria, and data collection involved preoperative assessment, patient preparation, operative measures, postoperative care, and follow-up evaluations using various scoring systems. Results: The range of motion showed a significant (P < 0.001) improvement over the study duration: flexion increased from 42.81° ± 11.81° at 6 weeks to 54.23° ± 14.95° at 12 months, and extension improved from 56.88° ± 13.28° to 68.38° ± 13.43°. In addition, there was a significant reduction in disability and wrist-related symptoms, as indicated by improvements in the Disabilities of the Arm, Shoulder, and Hand (DASH) scores (6 weeks: 25.80 ± 15.85 vs. 12 months: 5.27 ± 8.61; P < 0.01) and Patient-Rated Wrist Evaluation (PRWE) scores at the same follow-up intervals (6 weeks: 46.04 ± 22.49 vs. 12 months: 9.54 ± 12.03; P < 0.001). Chronic illness and injuries like triangular fibrocartilage complex tears affected outcomes negatively. Age, ulnar variance, and palmar tilt were significantly correlated with DASH and PRWE scores. Conclusion: Arthroscopic-assisted reduction and fixation for intra-articular DRFs resulted in favorable outcomes regarding the range of motion, disability, and wrist-related symptoms. Further research and long-term follow-up studies are recommended to validate the positive outcomes of arthroscopic-assisted reduction and fixation for intra-articular DRFs, compare it with other surgical approaches, and assess its economic implications.

Technique for Minimally Invasive, Arthroscopic-assisted Distal Radius Fracture Fixation.

Distal radius fractures are common injuries that often require surgical intervention. Commonly, these fractures are fixed using open reduction internal fixation with plating and screws. This often requires a more extensive soft tissue dissection and exposure. In contrast for certain cases, percutaneous headless compression screws may be appropriate. We present a technique for minimally invasive arthroscopic-assisted reduction and percutaneous screw fixation with an extremity traction device. A case is provided to demonstrate the technique as a viable option for the treatment of intra-articular distal radius fractures.

VARIABLE ANGLE LOCKING PLATE VERSUS MULTIPLE K WIRE FIXATION FOR INTRA-ARTICULAR DISTAL RADIUS FRACTURE: A PROSPECTIVE COMPARATIVE STUDY OF FUNCTIONAL OUTCOME IN ELDERLY

Distal radius fracture (DRF) is a common wrist injury and it accounts for about one-sixth of emergency department visits. In spite of availability of various treatment options, none is universally effective for comminuted intraarticular fracture, because of varied fractures patterns. Two commonly used surgical methods are multiple K-wire fixation and open reduction and internal fixation by variable angle locking plates. Objective of the study was to compare functional outcomes of variable angle locking plate and multiple K wire fixation for intra-articular distal radius fracture in elderly. Prospective observational study was conducted among the patients of distal radius fractures with age more than 50 years. Patients were divided in to two groups with 24 cases in each group. Group one included patients treated with variable angle locking plate and group two included patients treated with multiple K-wires. Post surgery patients were assessed at 6 weeks, 3, 6 and 12 months. Evaluation was done clinically, and the outcomes were assessed by using the Disabilities Arm, Shoulder and Hand (quickDASH) score (primary outcome), Patient-Rated Wrist Evaluation (PRWE) score, range of motion, grip strength and were compared between the groups. Patients treated with variable angle locking plate was found to have better functional outcome than those treated with multiple K-wire initially during the study, but later by the end of the study at 12 months, both groups were found to be having similar outcomes, with no significant difference between the groups. This signifies that among variable angle locking plate and multiple K-wire fixation, no single procedure is superior to the other in long term.

What to Expect? Use of Supplemental Fixation With a Concomitant Dorsal Spanning Plate for Complex Intraarticular Distal Radius Fractures.

The dorsal spanning plate (DSP) is a versatile implant suitable for bridging severely comminuted intraarticular distal radius fractures [AO (Arbeitsgemeinschaft für Osteosynthesefragen) 23-C.1-C.3]. It may be used alone or with supplemental fixation such as a volar locking plate (VLP) or fragment-specific fixation (FSF). Outcomes following DSP fixation with additional implants have not been specifically evaluated. We retrospectively reviewed consecutive patients who underwent internal fixation of a distal radius fracture by a single surgeon from 2017 to 2021. Patients were grouped according to implants used: DSP only, DSP + FSF, and DSP + VLP. Preoperative variables, treatment times, and wrist range of motion (ROM) were assessed. Functional wrist ROM was defined as minimum 80° combined flexion and extension. One hundred fifty-two patients underwent surgery for wrist fracture, 33 of them were treated with a DSP: 8 DSP only, 6 DSP + VLP, and 19 DSP + FSF. Falls from height greater than 10 ft accounted for 52% of injuries, most of which were treated with a DSP + FSF. Treatment times and ROM were similar between subgroups. Wrist ROM did not improve significantly beyond 4 weeks following DSP removal. Overall, DSP patients recovered a mean wrist ROM of 85° (range 0°-130°) within a median 26 weeks total treatment period (range 12-68 weeks). Regardless of the construct used, if the distal radius articular surface is well reduced and other principles of fracture fixation are applied, most patients treated with a DSP can expect to regain functional wrist ROM.

Wrist Radiographic Indices and Patients’ Performance Following Three Surgical Methods for Management of Distal Radius Fractures: A Randomized Single-Blind Controlled Trial

Background. Distal radius fracture has been reported as the most common type of extremity fractures in adults. No treatment method has been introduced definitely for this type of fracture, especially for maintaining hand function in the best state.
 The aim of this study — to assess the functional and radiological outcomes following three surgical methods, including external fixation, K-wire and external fixation with pinning.
 Methods. This parallel-designed randomized controlled trial was conducted on adult patients with intra-articular fracture of distal radius. The participants were allocated in three research groups with block random sampling, and were matched for their age and gender. Primary outcome was radiographic parameters, including radial inclination, radial height, ulnar variance and dorsal/palmar tilt. Secondary outcome was the patient’s performance examined with DASH and PRWE questionnaires. All participants were followed 6, 12 and 24 weeks after the surgery for evaluation of these outcomes.
 Results. Totally, 78 patients, including 42 male and 36 female with mean age of 46.94±11.05 years completed the research protocol. Although the four radiologic primary endpoints were in the normal clinical range after the intervention, a significant statistical difference was observed between the three groups (р0.001). Also, both DASH and PRWE score showed a significant decrease after the therapeutic interventions (р0.001).
 Conclusion. The statistically significant difference in the research outcomes of the external fixation with pinning can show that this treatment method theoretically preserves the anatomical condition better than the other two methods, and probably has better functional effects on short-term and intermediate-term results following the surgery.

Factors predicting complications following open reduction and internal fixation of intra-articular distal radius fracture.

This study aimed to determine the incidence and predictors of the complications after open reduction and internal fixation (ORIF) of intra-articular distal radius fracture (IADRF) with a minimum follow-up of 12 months. Medical records and outpatient follow-up records were retrospectively reviewed to collect medical, surgical, and complication data on consecutive patients who had undergone an ORIF procedure for an IADRF between January 2019 and June 2022. Data included demographics, comorbidities, injury, surgical characteristics, and laboratory findings on admission. A multivariate logistic regression model was constructed to identify the significant predictors, with a composite of any complications occurring within 12 months after the operation as the outcome variable and potentially a range of clinical data as the independent variables. The magnitude of the relationship was indicated by the odds ratio (OR) and the 95% confidence interval (CI). During the study period, 474 patients were included, and 64 had documented complications (n = 73), representing an accumulated rate of 13.5%. Among them, carpal tunnel syndrome was the most common, followed by tenosynovitis caused by tendon irritation/rupture, superficial or deep wound infection, complex regional pain syndrome (CRPS) type 1, radial shortening (≥4 mm), plate/screw problems, and others. The multivariate results showed the following factors significantly associated with increased risk of complications: experience of DRF surgery with <30 cases (OR: 2.2, 95% CI: 1.6-3.5), AO type C fracture (OR: 1.7, 95% CI: 1.2-2.9), initial lunate facet collapse of ≥5 mm (OR: 4.2, 95% CI: 1.4-8.9), and use of temporary external fixation before index surgery (OR: 2.4, 95% CI: 1.5-4.3). These findings may aid in patient counseling and quality improvement initiatives, and IADRF should be directed by an experienced surgeon.

Comparison of Low-Dose Computed Tomography Versus Conventional-Dose Computed Tomography in the Evaluation of Distal Radius Fractures.

Distal radius fractures (DRFs) are common upper extremity fractures and often require surgical fixation when they are intraarticular. Preoperative computed tomography (CT) has emerged as a surgical planning tool to evaluate intraarticular DRFs. Although CT affords additional details, patients receive higher radiation doses than standard radiographs. We aim to develop a low-dose CT (LDCT) protocol, relative to the institutional standard-dose CT wrist for intraarticular DRFs although providing adequate detail for surgical decision-making. A single-institution prospective study was conducted on patients with intraarticular DRFs who underwent closed reduction and below-elbow splinting who otherwise would undergo wrist CT. Observations were defined as total measurements taken, with each view undergoing 44 measurements. Patients underwent 2 scans with a standard dose and a 10× dose reduction. Articular step and gap measurements were recorded in the sagittal and coronal images. A total of 11 patients were enrolled (7 women and 4 men). The mean age was 55 years (SD = 20.1). There were a total of 4 reviewers: 1 attending surgeon, 2 resident physicians, and 1 student. When comparing LDCT and conventional-dose CT (CDCT), there were no significant differences in step and gap measurements across all reviewers. This study demonstrated that LDCT provides comparable imaging quality for surgical planning as a CDCT without significant diagnostic decay in the setting of DRFs. This comes with the added benefit of a 10-fold reduction in radiation exposure. These results suggest that LDCT is an opportunity to reduce effective radiation in patients although providing beneficial preoperative imaging.

Teardrop Alignment Changes After Volar Locking Plate Fixation of Distal Radius Fractures With Volar Ulnar Fragments.

We assessed factors associated with change in radiographic teardrop angle following volar locking plate (VLP) fixation of volarly displaced intra-articular distal radius fractures with volar ulnar fragments (VUF) within the ICUC database. The primary outcome was change in radiographic alignment on follow-up imaging, defined as a change in teardrop angle from intra-operative fluoroscopy greater than 5°. Patients with distal radius fractures treated with a VLP within the ICUC database, an international collaborative and publicly available dataset, were identified. The primary outcome was volar rim loss of reduction on follow-up imaging, defined as a change in radiographic alignment from intra-operative fluoroscopy, teardrop angle less than 50°, or loss of normal radiocarpal alignment. Secondary outcomes were final range of motion (ROM) of the affected extremity. Radiographic Soong classification was used to grade plate position. Descriptive statistics were used to assess variables' distributions. A Random Forest supervised machine learning algorithm was used to classify variable importance for predicting the primary outcome. Traditional descriptive statistics were used to compare patient, fracture, and treatment characteristics with volar rim loss of reduction. Volar rim loss of reduction and final ROM in degrees and as compared with contralateral unaffected limb were also assessed. Fifty patients with volarly displaced, intra-articular distal radius fractures treated with a VLP were identified. Six patients were observed to have a volar rim loss of reduction, but none required reoperation. Volar ulnar fragment size, Soong grade 0, and postfixation axial plate position in relation to the sigmoid notch were significantly associated (P < .05) with volar rim loss of reduction. All cases of volar rim loss of reduction occurred when VUF was 10.8 mm or less. The size of the VUF was the most important variable for predicting volar rim loss of reduction followed by postfixation plate position in an axial position to the sigmoid notch and the number of volar fragments in the Random Forest machine learning algorithm. There were no significant differences in ROM between patients with volar ulnar escape and those without.

Dorsal wrist plating for the management of intra-articular distal radius fractures.

The aim of the study was to evaluate the results of Dorsal Wrist Plating in intra-articular distal radius fractures with a dorsal displacement. In this prospective study, a single surgeon treated 20 patients with a (partially) intra-articular distal radius fracture with a dorsal rim avulsion or a dorsal Barton's type fragment. They all underwent an open reduction and internal fixation by Dorsal Wrist Plating. A total of 17 patients had a follow-up period of at least 12 months (mean follow- up of 17 months) and these patients were included in the study. Both functional and radiological outcome parameters were measured. The total range of motion was 92 % of the contralateral side. The mean grip strength and key pinch were 24.6 kg and 6.9kg respectively compared to 29.5 kg and 7.4 kg on the non-operated side. The average Mayo Wrist Score was 89.7 (range 80-100) and the mean Disability of the Arm, Shoulder and Hand score was 4.5 (range 0-9.2). An articular step-off was only noted in 2 patients (1 and 2 mm respectively). Radial inclination was restored in all patients. Palmar tilt was anatomically restored in five patients. In all other patients, the palmar tilt was acceptably restored. There was no significant radial shortening in any of the patients. No infections, no tendon ruptures, no Complex Regional Pain Syndrome, or union problems were observed. Dorsal wrist plating seems to be a safe and reliable procedure in the treatment of intra-articular distal radius fractures with dorsal displacement.

Post-surgical efficacy of early motion on intra-articular distal radius fracture and the effect of osteoporosis on outcomes

Aim: Post-surgical rehabilitation of intra-articular distal radius fractures in osteoporotic patients is still controversial. The aim of our study is to compare the effectiveness of early and late motion in intra-articular distal radius fractures in osteoporotic and non-osteoporotic patients. Materials and Methods: Eighty patients were included in our study. The patients were divided into two groups according to osteoporosis (OP), (OP +, OP -). Each group was also divided into 2 groups according to initiation of motion ((Early motion subgroup (E-MOT), Late motion subgroup (L-MOT)). Quick Disabilities of the Arm, Shoulder and Hand (Q-DASH), Patient-Rated Wrist Evaluation (PRWE) scores, Range of Motion (ROM) and grip strength were evaluated at final follow-up. Results: No significant difference was found among the groups in terms of age, gender ratio, right hand–left hand ratio, hand dominance, follow-up duration, or fracture classification. Contrary, the range of motion and functional results of OP+,E-MOT group were found to be more successful than the OP+,L-MOT group, there was no significant difference between the OP-,EMOT group and the OP-,L-MOT group. Conclusion: Early motion has a positive effect on the results in osteoporotic patients compared to late motion, while it does not significantly affect outcomes in non-osteoporotic patients. Early motion after surgery for intra-articular distal radius fractures is crucial for osteoporotic patients, but less so for non-osteoporotic patients.

An Assessment of Distraction Plating in the Management of Intra-Articular Comminuted Distal End Radius Fractures in the Elderly

Abstract Background: Distal radius fractures are one of the most common injuries, representing one-sixth of all fractures seen and treated in the emergency department. Distal radial fractures with extensive comminution involving the metaphyseal–diaphyseal junction present a major treatment dilemma, especially when it has an intra-articular involvement. This study evaluates the surgical and functional outcomes of intra-articular comminuted fracture of distal end radius treated with dorsal distraction plating. Materials and Methods: A prospective randomized controlled observational study was done with a sample size of 50 patients over a period of 3 years, each of whom was diagnosed to have an intra-articular fracture of distal end radius (AO classification type C). All patients were treated by distraction plating (radio-metacarpal). Minimum follow-up after treatment of upto 6 months was ensured, and a final assessment of the functional outcome was then decided. Results: The study showed that average union time was 8.65 ± 0.93 weeks, and average implant removal was done at 8.75 ± 0.85 weeks. All patients achieved full ROM at the wrist, maintaining articular congruity post-implant removal. In our study, we found two (6.67%) patients with superficial infections and two (6.67%) patients with complex regional pain syndrome. No patients were reported with the tendon (extensor pollicis longus) irritation, neuropraxia, stiffness of the wrist and inter-phalangeal joints, nonunion/malunion, or implant failure. Conclusion: The final results were evaluated and compared after making observations for age, sex, mode of trauma, dominancy of the affected hand, time interval between injury and admission, duration of hospital stay, duration of surgery, time to fracture union, and complications. The final outcome was measured by DASH SCORE. All patients had excellent or good results treated with distraction plating; six (20.00%) patients out of 30 studies were found to have excellent results, whereas the remaining 24 (80.00%) patients had good results.

Investigation Into the Effects of Intra-Articular Steroid on Post-Traumatic Osteoarthritis in Distal Radius Fractures: A Randomized Controlled Pilot Study

The aim of this prospective, randomized, controlled, double-blinded pilot study was to determine the rates of post-traumatic osteoarthritis and assess joint space width in the presence or absence of a single intra-articular injection of corticosteroid after an acute, intra-articular distal radius fracture (DRF). Forty patients received a single, intra-articular, radiocarpal joint injection of 4 mg of dexamethasone (DEX) (n= 19) or normal saline placebo (n= 21) within 2 weeks of a surgically or nonsurgically treated intra-articular DRF. The primary outcome measure was minimum radiocarpal joint space width (mJSW) on noncontrast computed tomography scans at 2 years postinjection. Secondary outcomes were obtained at 3 months, 6 months, 1 year, and 2 years postinjection and included Disabilities of the Arm, Shoulder, and Hand; Michigan Hand Questionnaire; Patient-Rated Wrist Evaluation; wrist range of motion; and grip strength. At 2-year follow-up, there was no difference in mean mJSW between the DEX group (2.2 mm; standard deviation, 0.6; range, 1.4-3.2) and the placebo group (2.3 mm; standard deviation, 0.7; range, 0.9-3.9). Further, there were no differences in any secondary outcome measures at any postinjection follow-up interval. Radiocarpal joint injection of corticosteroid within 2 weeks of an intra-articular DRF does not appear to affect the development of post-traumatic osteoarthritis within 2 years follow-up in a small pilot cohort.

Does simultaneous comminuted fracture of both radial ends represent a distinct fracture pattern?

Although isolated distal radius and radial head fractures are common injuries, simultaneous ipsilateral fractures are uncommon. They can range from simple undisplaced fractures at either end to severely comminuted ipsilateral proximal and distal radial fractures. Few cases have been reported with concomitant comminuted distal radius and radial head fractures, and no treatment guidelines are available. Decisions are often based on personal recommendations. The purpose of our study is to increase awareness of this injury pattern and to discuss the mechanism of injury, treatment approach, and functional outcome. Skeletally mature patients with comminuted simultaneous ipsilateral fractures of the distal and proximal radius from 2016 to 2021 were identified and studied retrospectively. Demographic information, mechanism of injury, treatment approach, and complication rate were analyzed. Radiographic assessment for inadequacy or loss of reduction and radiographic parameters of the distal radius, including radial inclination, radial length, and palmar inclination, was performed immediately postoperatively and at the final follow-up. Clinical outcomes were determined by calculating the Visual Analog Scale (VAS) score, measuring the range of motion in both joints, and using the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score at the final follow-up. A total of 11 patients met the inclusion criteria. All had ipsilateral Mason III radial head fractures and type C (according to the Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification) intra-articular distal radius fracture. On-table radial head reconstruction and fixation with a proximal radius plate were used for radial head fractures, and osteosynthesis with an anatomic volar locking plate was used for distal radius fractures. The mean follow-up duration was 32 months (range 12-65 months). At the final follow-up, osseous union of both the radial head and distal radius was observed in all patients. The mean VAS score was 1.5 (range 0-7) at rest and 3.9 (range 0-9) with activities, while the mean QuickDASH score was 32 (range 12-65). No significant complications were recorded. Simultaneous comminuted fractures of the ipsilateral distal radius and radial head represent a distinct injury pattern, most likely resulting from high-energy trauma, such as falling from a height onto an outstretched hand. Greater emphasis should be placed on clinical examination and radiological imaging of the elbow in cases of wrist injuries and vice versa. Treatment involving on-table reconstruction of the radial head and open reduction and internal fixation with a volar plate can lead to good radiological and functional outcomes.

External fixation versus volar locking plate fixation as treatments for intra-articular distal radius fractures in patients aged 60 years and older

FUNCTIONAL OUTCOME OF INTRAARTICULAR DISTAL RADIUS FRACTURE TREATED WITH OPEN REDUCTION AND INTERNAL FIXATION WITH DORSAL PLATE

Background: Distal radius fractures are among the most common fractures and there is considerable disparity among surgeons regarding the best way to treat these patients. Intraarticular fractures are treated with open reduction and internal fixation with either dorsal or volar plates. Dorsal plating is not much popular due to its reported complications of extensor tendon irritation and rupture. We conducted this study to assess the functional outcome of dorsal plating in intraarticular distal radius fractures. Methods: A clinical prospective observational study was conducted at Kathmandu Medical College,Sinamangal. A total of 26 patients (male: 14; female: 12) of intraarticular distal radius fractures were enrolled and underwent open reduction and internal fixation using the dorsal plate. The functional outcome of dorsal plating was measured at 3 weeks,3 months and 6 months follow up. Results: All patients achieved a functional range of motion, with greater than 50 degrees of wrist flexion, 25 degrees of wrist extension, and 60 degree arc of pronation and supination. The functional outcome measured was found to be good to excellent with a mean Mayo Wrist score of 89.23(75-100) and Quick Dash-9 score of 9.20(2.75 to 22). There were 3 cases of extensor tendon irritation, which completely resolved and no cases of extensor tendon irritation at final follow up. Conclusions: Dorsal plating is a safe and effective way of treating intra articular distal radius fracture with good functional outcome.
