In cases of distal radius fractures, the fixation of the volar lunate facet fragment is crucial for preventing volar subluxation of the carpal bones. This study aims to clarify the sex differences in the volar morphology of the lunate facet of the distal radius and its relationship with the transverse diameter of the distal radius. Sixty-four CT scans of healthy wrists (30 males and 34 females) were evaluated. Three-dimensional (3D) images of the distal radius were reconstructed from the CT data. We defined reference point 1 as the starting point of the inclination toward the distal volar edge, reference point 2 as the volar edge of the joint on the bone axis, and reference point 3 as the volar edge of the distal radius lunate facet. From the 3D coordinates of reference points 1 to 3, the bone axis distance, volar-dorsal distance, radial-ulnar distance, 3D straight-line distance, and inclination angle were measured. The transverse diameter of the radius was measured, and its correlations with the parameters were evaluated. It was found that in males, compared to females, the transverse diameter of the radius is larger and the protrusion of the volar lunate facet is greater. This suggests that the inclination of the volar surface is steeper in males and that the volar locking plate may not fit properly with the volar cortical bone of the lunate facet, necessitating additional fixation.

Background: Fractures of the distal radius are among the most common bone injuries, and their frequency is constantly increasing, leading to an elevated need for subsequent rehabilitation. This growing need has led to the emergence of online content aimed at providing guidance on rehabilitation. Nonetheless, unreviewed online content raises concerns about its reliability; therefore, the objective of this study was to evaluate the quality, reliability, and comprehensiveness of online videos concerning rehabilitation following a distal radius fracture. Methods: A total of 240 YouTube videos were screened, identifying 33 videos that met the inclusion criteria. These selected videos were evaluated by five independent experts from various professional groups, using the Global Quality Scale, the DISCERN reliability tool, and the JAMA Benchmark Score, as well as a structured set of questions to assess their comprehensiveness and coverage of pertinent aspects. Results: The observers\' assessment of the Global Quality Scale exhibited a broad spectrum of viewpoints, indicating considerable variability in evaluations. In most cases, therapy aligned well with the diagnosed condition, and most raters deemed the indication and instruction in the videos acceptable. A proportion of 87% of the videos was deemed suitable for home training by at least three raters. However, a concerning trend emerged, as potential risks and pitfalls were scarcely addressed. Conclusions: The moderate overall quality of the videos and the divergence in expert opinions highlight the need for a regulatory authority to ensure adherence to guidelines and maintain high-quality content. Additionally, our results raise concerns about the applicability of established assessment tools in this context.

UNASSIGNED: Release of the first dorsal compartment is a described technique during volar approach for distal radius fracture fixation. Our objective was to determine whether release of the first dorsal compartment during volar approach for distal radius fracture fixation impacted corresponding symptoms in pre-existing de Quervain disease.
UNASSIGNED: A prospective, randomized cohort study was performed with patients grouped for release (release group) or no release (control group) of the first dorsal compartment during volar approach for distal radius fracture fixation. Inclusion required a confirmed diagnosis of de Quervain disease within the 12 months preceding a distal radius fracture.
UNASSIGNED: Patients in the release group were significantly less symptomatic than those in the control group at 3 and 6 months after surgery. Lateral pinch strength in the release group was significantly greater than that in the control group at 3 and 6 months after surgery.
UNASSIGNED: The current results demonstrated a significantly greater reduction in de Quervain disease symptoms in the release group compared with the no release group during the short-term follow-up. This indicates that routine first dorsal compartment release during distal radius fracture fixation may expedite symptom relief in patients with de Quervain disease.
UNASSIGNED: Therapeutic I.

The authors report on the case of a 30-year-old male who sustained a wrist injury following a motorcycle accident. Emergency department evaluation revealed a left open distal radius fracture with distal radioulnar joint dislocation. The patient underwent surgical fixation to restore full mobility of his wrist.

UNASSIGNED: Ultrasound-guided manipulation and reduction (M&R) of the distal radius fractures (DRF) is believed to improve radiographic indices due to real-time feedback of fracture alignment. The objective of this trial was to compare volar tilt, radial inclination, and radial height on radiographs between Ultrasound guided and conventional (landmark-guided) M&R.
UNASSIGNED: A total of 79 distal radius extraarticular fractures in adults were randomised to Ultrasound guided and conventional (landmark-guided) M&R. The radiograph parameters described above were compared before and after M&R in both groups.
UNASSIGNED: Except for volar tilt (P=0.05 difference in difference), there was no difference in both the groups on radiograph parameters i.e. radial inclination and radial height. We estimated a reduction in the incidence of malreduction by 49% (Risk ratio 0.51) and an absolute risk reduction of 22% through USG-guided reduction. We evaluated a number needed to treat 4 through USG-directed M&R of DRF to prevent one unacceptable reduction. There were 9 (22%) and 18 (46%) (P=0.70) unacceptable reductions in USG-guided and landmark-guided M&R.
UNASSIGNED: Adding USG guidance to conventional landmark-based closed reduction methods is not beneficial for the accuracy of fracture reduction in Colle\'s fracture. However, improved volar tilt in sonographic-directed M&R needs further studies to determine the clinical significance.

Objectives Our hospital was newly opened in the spring of 2020 in a rural area of Japan, with a remarkably developing aging society and population decline. This study aimed to clarify and evaluate the practice of osteoporosis care in our hospital for three years since its establishment. We report a retrospective review of therapeutic interventions for osteoporosis for patients who underwent surgical treatment for non-vertebral fragility fractures in our hospital. Methods We evaluated the practice of osteoporosis intervention in patients who underwent surgery for proximal humerus fractures (PHFs), distal radius fractures (DRFs), or proximal femoral fractures (PFFs) from April 2020 to the end of March 2023. Results There were 115 surgical cases with non-vertebral fractures (10 patients with PHF, 41 patients with DRF, and 64 with PFF). Among the patients who had received osteoporosis treatment at other hospitals before the injury, only 15 (13.0%) patients had been administered therapeutic intervention for osteoporosis by other clinics or hospitals. Also, 82 (71.3%) patients were newly diagnosed with osteoporosis in our hospital after surgery according to the Japanese osteoporosis guideline. New postoperative osteoporosis interventions were administered to 39 (47.0%) patients, of which the rate was higher than the previous reports in Japan. While there was no significant difference between upper limb fracture and PFF in the percentage per young adult mean of spine areal bone marrow density (aBMD), the femoral neck aBMDs in the upper limb fracture group were significantly higher than in the PFF group. The serum total P1NP levels were significantly lower and the 25(OH)D levels were also greater in the upper limb fracture group than in the PFF group, whereas the serum TRACP-5b levels were not significantly different between the two groups. Two (1.7%) patients were affected with secondary fractures during the study period. Conclusions The rates of therapeutic intervention for osteoporosis of patients with non-vertebral fractures, especially in those with upper limb fractures, in our hospital were considered to be greater than those in the previous reports. However, the intervention rate for patients with PFFs was not much, and there was still room for improvement in our hospital concerning osteoporosis diagnosis and treatment.

BACKGROUND: Due to its ability to provide stable fixation and permit early mobilization, volar plating has become the recommended technique for the surgical stabilization of distal radius fractures. The extensor pollicis longus (EPL) tendon may be injured or ruptured as a result of undetected screw penetration or drill plunging. During surgery, it is critical to detect any potential screw penetration so that it can be corrected.
METHODS: A 32-year-old woman presented six weeks post-distal radius plating with an inability to extend her left thumb. Clinical examination revealed loss of extension at the interphalangeal joint, stiff wrist, tender point over the dorsal aspect of the wrist, and an intact sensory nerve function.
CONCLUSIONS: Dynamic ultrasound and magnetic resonance imaging (MRI) both revealed no evidence of tendon rupture or EPL tendon movement. X-rays revealed the distal epiphyseal screws penetrating the far cortex. Intraoperatively, the EPL tendon was found to be impinged by a screw. The tendon was released, tenolysis was performed, and the distal screws were shortened.
CONCLUSIONS: In order to assess screw penetration into the far cortex, volar plating for distal radius fractures should be performed using intraoperative imaging views such as lateral, 45-degree supination, 45-degree pronation, dorsal tangential, and skyline views. Timely interventions after distal radius fracture fixation preserve tendon function, and early detection of tendon compromise is essential to preventing additional damage.

BACKGROUND: The aim of this study was to determine the clinical outcomes of conservative and surgical treatments in elderly patients with displaced Frykman type 7-8 distal radius fractures.
METHODS: The clinical outcomes of 50 patients aged 60 and older with displaced Frykman type 7-8 fractures who underwent surgical and conservative treatments between January 2019 and January 2022 were determined. The joint range of motion, pain scores, functional scores, radiological parameters, and any complications that occurred posttreatment were evaluated for each patient who underwent both treatments.
RESULTS: Descriptive characteristics, excluding sex, were evaluated in 18 patients treated with casting and 32 patients treated with volar plating, and no statistically significant differences were detected between the groups. The functional and radiological assessments of the groups showed no significant differences (p>0.05). The volar tilt of patients who underwent surgical treatment was significantly greater than that of patients who were treated with a cast (p=0.02). The Mayo wrist scores of patients with step-offs greater than 2 mm were significantly lower (p=0.007; p<0.01). The visual analog scale (VAS) scores of patients who met the step-off criterion were significantly greater (p=0.025; p<0.05). The Mayo wrist scores of patients whose radiological parameters were within acceptable limits were significantly greater (p=0.007; p<0.01). The Quick-Quick Disabilities of the Arm, Shoulder, and Hand (DASH) scores of patients whose radiological parameters were within acceptable limits were significantly lower (p=0.007; p<0.01).
CONCLUSIONS: In elderly patients with identified Frykman type 7-8 fractures, casting and volar plating treatments produced similar results. Especially in patients with low expectations and multiple comorbidities, satisfactory results can be achieved with plaster treatment.

UNASSIGNED: Distal radius fractures account for nearly one-third of all pediatric fractures, making it among the most common of all pediatric fractures. Studies report that distal radius physeal arrest rates following trauma to the distal radius seem to occur in only about 5% of patients. Significant ulnar variance can develop leading to notable pain and limitations in function.
UNASSIGNED: We present a case of a 17-year-old right-hand dominant adolescent Caucasian male with persistent ulnar wrist pain. The patient presented to our outpatient clinic for evaluation of his left wrist following 6-8 months of persistent ulnar-sided pain. Ten months prior, the patient had fallen off a shed and was treated in the emergency room and referred to the outpatient clinic for follow-up. The patient initially sustained a Salter-Harris Type 2 distal radius fracture treated with closed reduction and short arm cast application in the emergency room. The short arm cast was removed at 8 weeks, and then, the patient was placed in a brace. The patient was lost to follow-up before returning to the clinic 16 months after the original injury when he noticed worsening pain in the left wrist, localized to the distal radioulnar joint with increased hand usage at a new job. Radiographs at that time showed a worsening positive ulnar variance as well as a partially open distal ulnar physis. After 6 months of occupational therapy and over-the-counter pain management, the ulnar-sided pain had not resolved. The radiograph showed a positive Ulna variance of 2.5 mm, which was corrected with a 5 mm excision osteotomy of the distal ulna. The patient reported significant pain relief and a 42-point improvement in his patient-rated wrist evaluation score.
UNASSIGNED: Distal radius growth arrest, while uncommon, can present with ulnar-sided pain and positive ulnar variance that is safely treatable with ulnar shortening osteotomy.

OBJECTIVE: To compare the clinical outcomes between nonsurgical and surgical treatment of distal radius fracture.
METHODS: We performed a systematic literature search by using multiple databases, including Medline, PubMed, and Cochrane. All databases were searched from the earliest records through February 2023. The study compared nonsurgical versus surgical treatment of distal radius fractures and included only randomized controlled trials (RCTS).
RESULTS: There were seventeen randomized controlled trials retrieved. A total of 1730 patients were included: 862 in the nonsurgical group and 868 in the surgical group. The results showed a significant reduction in DASH score with surgical treatment (WMD 3.98, 95% CI (2.00, 5.95), P < 0.001). And in grip strength (%), the results showed a significant improvement in surgical treatment compared with non-surgical treatment (WMD - 6.60, 95% CI (-11.61, -1.60), P = 0.01). There was significant difference in radial inclination, radial length, volar title, range of wrist pronation, range of wrist supination. However, no difference in radial deviation, ulnar deviation, ulnar variance, range of wrist extension and range of wrist flexion was observed.
CONCLUSIONS: The results of this meta-analysis suggest that some patients with surgical treatment of distal radius fractures not only improved the grip strength (%), decreased the DASH score, but also improved the range of wrist pronation and the range of wrist supination compared with nonsurgical treatment. Based on the present meta-analysis, we suggest that some patients with surgical treatment might be more effective in patients with distal radius fracture.
