Abstract Introduction: Malunion is the most frequent complication of fracture distal radius. Fracture malunion has been shown to associate with altered morphometric anatomy of distal radioulnar joint. Objective: This study aims to identify normal radiographic morphometry reference values and variations according to age and sex of distal radioulnar joint. This study was also carried out to determine the radiological correlation between normal and malunited distal radius in patient with unilateral malunited fracture to find out the effect of malunited fractured distal end of radius on the morphometric parameters of distal radioulnar joint. Materials and Methods: After twelve weeks of injury x-ray of injured wrist was compared with the radiograph of the contra lateral normal wrist for the difference in radial length, radial inclination, ulnar variance and palmar tilt. Results: Results of this study showed that there were signiicant difference in distal radius parameters between genders for both groups except for the difference in palmer tilt i.e. since value of P< 0.0001 so there is significant difference between two group 1% level of significant suggesting that with 99% confidence, there is significant difference between mean of normal male and female right wrist parameters of both age group except for palmer tilt. Similarly there were variations in all parameter measurements for those x-ray films showing severe malunion and signiicant differences were noted for all parameters distal radius between normal and malunited wrist in both age groups i.e. since value of P< 0.0001 so there is significant difference between two group 1% level of signiicant suggesting that with 99% conidence, there is signiicant difference for all parameters between mean of normal and malunion group. Conclusion: These results can be used in treatment of the malunited distal radius for correction of deformity at the wrist and achieving the best possible anatomical reduction in the young active patient and at minimizing the intervention in the low demand elderly patient with multiple comorbidities. These data also can be used for clinical research in the designing of wrist implants.

Injury to the triangular fibrocartilage complex associated with distal radius fracture may cause symptoms of ulnar instability. Assessed by a radioulnar stress test, increased laxity of the distal radioulnar joint has in two previous studies been depicted to be associated with poorer outcome. This prospective study of 40 adults investigates the correlation of this test with functional outcome as measured by DASH. No clinically significant difference was found in relation to this test at two and five years after injury. Therefore using this test alone to decide whether or not to perform an acute repair of the TFCC cannot be recommended.

Objectives: The main goal of this research was to determine the differences between the values of intraocular pressure (IOP) in the supine and sitting positions, and to assess the effect of age and cardiovascular parameters. Methods: Seventy-two healthy adults were enrolled and classified into age groups: 20–30 years (group A), 31–40 years (group B), and 41–71 years (group C). Corneal biometry and cardiovascular parameters, such as heart rate (HR), were measured. IOP measurements were taken in the sitting position (IOPS) and in the supine position (IOPL) using the iCare® Pro tonometer. Results: A significant difference between the IOPS and IOPL in the entire cohort was found ( p < 0.001). Regarding the age subgroups, a significant difference ( p < 0.001) between the IOPS and IOPL was obtained in group A (2.6 ± 1.6 mmHg) and group C (1.5 ± 1.3 mmHg). There were no significant differences in the IOPS between groups. The highest IOP values were obtained for group A. The correlations between HR and IOPS are statistically significant for group A and group B, and for HR and IOPL-S for group B only. Multivariate analysis showed that HR has a significant influence on the difference in IOP in the two body positions. Conclusion: A statistically significant difference between the effect of age and the values of IOPS and IOPL was shown. Cardiovascular parameters showed some relevant statistical dependencies, but with a rather marginal significance in young people. The influence of body position for the measurement of IOP for healthy subjects does not seem to matter, despite the fact that there are some dependencies that are statistically significant.

Objective: Carbohydrate antigen 72-4 (CA72-4) is widely used in the diagnosis and monitoring of many cancers. However, there are few studies on the differences of CA72-4 levels in terms of age and gender. Methods: 10957 healthy subjects were divided into two groups according to gender and three age groups. The serum CA72-4 were detected. Statistical analysis was performed by SPSS. Results: The CA72-4 level in female group was significantly higher than that in male group. The level of CA72-4 gradually decreased with age. Compared with the age >60 group, the CA72-4 levels were increased in the age 46-60 group and 16-45 group (P >0.05, respectively). To better observe the age difference, the age 16-45 and 46–60 group were combined into the age 16-60 group. In comparison to the age >60 group, the CA72-4 level of age 16-60 group was significantly increased (P =0.000). In the age >60 group, there was no difference between genders. Nevertheless, the difference between the sexes in the age 16-60 group was significant (P =0.023). Conclusions: The reference interval of CA72-4 for local healthy population was established. CA72-4 levels gradually decreased with the increase of age, and CA72-4 level in females aged 16-60 years (0-18.0 U/mL) was higher than in males (0-14.5 U/mL), however there was no gender difference in the age group above 60 years old (0-14.5 U/mL). Moreover, male CA72-4 was no significant difference among all age groups, while the potential mechanism of female changes with age needed further study.

The incidence of distal radioulnar joint instability following a distal radius fracture is estimated around one in three based upon clinical examination. Using a validated rig, we objectively measured distal radioulnar joint translation in vivo following distal radius fracture. Dorsopalmar translation of the distal radioulnar joint was measured in 50 adults with previous distal radius fractures. Measurements were compared with the uninjured wrist and against a database of previous measurements within healthy and clinically lax populations. Translation at the distal radioulnar joint was greater in injured wrists at 12.2 mm (range 10–15, SD 1.2) than the uninjured wrists at 6.4 (range 4–9, SD 0.8) ( p < 0.001) and was always outside the established normal range. There was no statistically significant link between translation and the severity of the injury. Instability appears almost inevitable following a distal radius (wrist) fracture, albeit subclinical in the vast majority.

Abstract Objective This study aimed to compare the necessary scutum defect for transmeatal visualisation of middle-ear landmarks between an endoscopic and microscopic approach. Method Human cadaveric heads were used. In group 1, middle-ear landmarks were visualised by endoscope (group 1 endoscopic approach) and subsequently by microscope (group 1 microscopic approach following endoscopy). In group 2, landmarks were visualised solely microscopically (group 2 microscopic approach). The amount of resected bone was evaluated via computed tomography scans. Results In the group 1 endoscopic approach, a median of 6.84 mm3 bone was resected. No statistically significant difference (Mann–Whitney U test, p = 0.163, U = 49.000) was found between the group 1 microscopic approach following endoscopy (median 17.84 mm3) and the group 2 microscopic approach (median 20.08 mm3), so these were combined. The difference between the group 1 endoscopic approach and the group 1 microscopic approach following endoscopy plus group 2 microscopic approach (median 18.16 mm3) was statistically significant (Mann–Whitney U test, p < 0.001, U = 18.000). Conclusion This study showed that endoscopic transmeatal visualisation of middle-ear landmarks preserves more of the bony scutum than a microscopic transmeatal approach.

Background The effects of dorsal angulation deformity on in vitro distal radioulnar joint (DRUJ) contact patterns are not well understood. Purpose The purpose of this study was to utilize intercartilage distance to examine the effects of forearm rotation angle, distal radius deformity, and triangular fibrocartilage complex (TFCC) sectioning on DRUJ contact area and centroid position. Methods An adjustable implant permitted the creation of simulated intact state and dorsal angulation deformities of 10, 20, and 30 degrees. Three-dimensional cartilage models of the distal radius and ulna were created using computed tomography data. Using optically tracked motion data, the relative position of the cartilage models was rendered and used to measure DRUJ cartilage contact mechanics. Results DRUJ contact area was highest between 10 and 30 degrees of supination. TFCC sectioning caused a significant decrease in contact area with a mean reduction of 11 ± 7 mm2 between the TFCC intact and sectioned conditions across all variables. The position of the contact centroid moved volarly and proximally with supination for all variables. Deformity had a significant effect on the location of the contact centroid along the volar–dorsal plane. Conclusion Contact area in the DRUJ was maximal between 10 and 30 degrees of supination during the conditions tested. There was a significant effect of simulated TFCC rupture on contact area in the DRUJ, with a mean contact reduction of 11 ± 7 mm2 after sectioning. Increasing dorsal angulation caused the contact centroid to move progressively more volar in the sigmoid notch.

Abstract BackgroundThe surgical technique of radius distraction for stabilization of distal radioulnar joint (DRUJ) if intraoperative DRUJ instability was found after the fixation of distal radius fracture has been previously described, but this surgical technique lacks clinical and radiographic effect in minimal 3 years follow-up. We therefore evaluated the clinical outcome and radiographic results of radius distraction in minimal 3 years follow-up.MethodsWe reviewed the case series of distal radius fracture with concomitant DRUJ instability receiving radius distraction from the senior author over a 5-year period (January 1st, 2013 to June 30th, 2017) retrospectively, and the evaluation of clinical and radiographic outcomes was performed at clinic as long-term follow-up; a total 34 patients had been evaluated.ResultsAt minimal post-operative 36 months follow-up, all cases demonstrated acceptable wrist range of motion with stable DRUJs and low NRS of wrist pain (0.6, SD 0.7) and DASH score (mean 9.1, SD 6.2), and there were no cases suffering from nonunion of distal radius. The mean ulnar variance of injured wrist and uninjured wrist were − 1.2 mm and 0.2mm, respectively (SD 1.0 and 0.6) with significant statistical difference.ConclusionsRadius distraction during volar fixation of distal radius fracture should be consider if DRUJ instability was found by the radioulnar stress test intraoperatively, and the long-term DRUJ stability could be achieved by maintenance of normal-to-negative ulnar variance, with decreased wrist pain and satisfactory function outcome.Level of EvidenceTherapeutic Level IV

Background: Different methods are found for mesh fixation in inguinal hernioplasty both open and laparoscopic. In open technique, sutures have been the method of choice for their reduced costs and surgeons’ habits. Whether absorbable instead of non-absorbable sutures can be used still a matter of debate in view of hernia recurrence and post-operative complications.Methods: This is a prospective done on 158 male patients with uncomplicated unilateral inguinal hernias. Two groups of 69 patients were evaluated after periods up to 1 year after open hernioplasty by using delayed absorbable sutures in one group (group 1) and non-absorbable sutures in the other group (group 2) for fixation of mesh.Results: In spite of a noticeable reduction in complication in the group 1 in term of number and percentage when compared with group 2 mainly chronic pain, there is no significant difference (p value>0.05). However, these results are associated with zero recurrence in both groups during a period of one year follow up.Conclusions: Delayed absorbable sutures are good alternative of non-absorbable sutures in open mesh hernia repair associated with less complications and almost no increase in chance of recurrence.
