Abstract Introduction The aim of this study was to provide a more precise statement on the outcome after surgical treatment of a bony mallet thumb and possibly give a treatment recommendation regarding the surgical fixation method. Patients and methods All patients (n = 16) who underwent a surgical treatment for an acute bony mallet thumb fracture between January 2006 and July 2019 were enrolled. The surgical method, complications, the range of motion, tip pinch, lateral key pinch, overall grip strength, visual analog score, Disability of the Arm, Shoulder and Hand Score, Mayo Wrist Score, Patient-Rated Wrist Evaluation Score, Buck-Gramcko Score and radiologic parameters were evaluated. Further, a comprehensive literature search on PubMed was conducted covering a period from 1956 to 2021 to include all possible matching articles on the treatment of the bony mallet thumb (n = 21 articles). Results Surgical treatment was very inhomogenous including indirect and direct K-wire fixation, screw fixation, plate fixation and anchor fixation methods. The IP joint range of motion and thumb strength ranged from 66 to 94% in comparison to the contralateral side. An open reduction led to worse functional scores compared to a closed reduction. Treatment methods in the literature were also very inhomogenous with a very low patient count, often even pooling data of bony mallet thumb fractures with bony mallet finger fractures. The risk for infection was higher in K-wire fixation methods than in open reduction and internal fixation methods. Conclusion The evidence for the best treatment of a bony mallet thumb fracture is low. On one hand the functional outcome can be inferior using an open reduction approach, but on the other hand, K-wire fixation methods with a closed reduction approach showed a higher risk for infection. Future multi-center research must be conducted to find the best treatment procedure for the best outcome of the patient.

Background. Unstable and comminuted distal radial fractures require surgical treatment by percutaneous insertion of Kir­schner wires, open reduction and fixation with a non-locking or locking plate or with an external device. The aim of this paper was to try to answer the following question: are there differences in functional treatment outcomes in patients after surgery with the use of Kirschner wires vs LCP plate fixation? Material and methods. The study group included 100 patients after surgical treatment by closed reduction and simple fixation with Kirschner wires (50 patients) and by open reduction and LCP locking plate fixation (50 patients). The study assessed the following parameters: global grip strength, pain severity in a VAS scale, range of motion, functional status of the wrist based on the Fernandez classification, quality of life according to the QuickDASH score, and the frequency of complications. These parameters were assessed at 6 and 12 months after surgery. Results. An assessment of the treatment outcomes at 6 and 12 months after surgery showed statistically significant differences between the treatment methods in the following parameters: pain severity, global grip strength and range of motion in the sagittal plane. A comparison of the functional status of the wrist at 6 and 12 months between the groups showed considerably worse results in the Kirschner wire fixation group. The frequency of postoperative complications at 12 months was 6% in the Kirschner wire fixation group and 2% in the LCP plate fixation group. Conclusions. 1. Treatment outcomes were better in patients with distal radial fractures managed with LCP plate fixation. 2. The use of LCP plate fixation predisposes pa­tients to better ranges of mobility in the sagittal plane in the radiocarpal joint. 3.The values of global grip strength were higher in the group treated with LCP plate fixation. 4. Patients treated with LCP plates have better limb function and quality of life and lower pain intensity after treatment completion. 5. The number of complications was higher in pa­tients treated with Kirschner wire fixation.

Abstract Background Restoration of articular surface alignment is critical in treating intra-articular distal radius fractures. Dorsal spanning plate fixation functions as an internal distraction mechanism and can be advantageous in the setting of highly comminuted fracture patterns, polytrauma patients, and patients with radiocarpal instability. The addition of K-wires to support articular surface reduction potentially augments fracture repair stability. Questions/Purposes We examined the radiographic outcomes and maintenance of reduction in patients with comminuted intra-articular distal radius fractures treated with K-wire fixation of articular fragments followed by dorsal spanning plate application. Patients and Methods We reviewed 35 consecutive patients with complex intra-articular distal radius fractures treated with dorsal spanning plate and K-wire fixation between April 2016 and October 2019. AO classification was recorded: B1 (3), B3 (2), C2 (2), C3 (28). A two-tailed paired t-test was used to compare findings immediately post-dorsal spanning plate surgery and at final follow-up after dorsal spanning plate removal. Results Mean patient age was 43.3 years (19–78 years). Mean follow-up was 7.8 months (SD 4.3 months) from surgery and 2.5 months from pin removal (SD 2.6 months). All patients achieved radiographic union. Radial height (mean interval change (MIC) 0.2 mm, SD 2.2, p = 0.63), articular step-off (MIC 0.1 mm, SD 0.6 mm, p = 0.88), and radial inclination (MIC −1.1 degrees, SD 3.7 degrees, p = 0.10) did not change from post-surgery to final follow-up. Ulnar variance (MIC −0.9 mm, SD 2.0 mm, p = 0.02) and volar tilt (MIC −1.5 degrees, SD 4.4 degrees, p = 0.05) were found to have decreased. Conclusion Dorsal spanning plate augmented with K-wire fixation for comminuted intra-articular distal radius fractures in polytrauma patients allows for immediate weightbearing and maintains articular surface alignment at radiographic union and may provide better articular restoration than treatment with dorsal spanning plate alone. Level of Evidence This is a Level IV, therapeutic study.

The evaluation of trauma after surgery through objective analysis of biochemical markers can help in selecting the most appropriate therapy. Thus the aim of the study was the evaluation of the concentration of selected inflammatory cytokines (IL-6, IL-8, CXCL5, IL-33), C-reactive protein (CRP), and damaged-associated molecular patterns (DAMPs): HMGB-1, HSP-70 in the plasma of children in response to bone fracture and 12-14 hours after subsequent surgery performed by closed reduction with percutaneous Kirschner wire fixation (CRKF). The study will answer the question if the CRFK procedure leads to excessive production of inflammatory and damage markers. Blood samples from 29 children with distal forearm fractures were collected 30 min. before CRKF procedure and 12-14 hours after performance of the procedure. The control group was composed of 17 healthy children. IL-6 and CRP concentrations were analyzed using routinely performed in vitro diagnostics tests; the remaining proteins were analyzed with the use of the ELISA method. Increased values of IL-6, CRP, and HSP-70 represented an early inflammatory response to distal forearm fractures classified as SH-II type according to the Salter-Harris classification system. However, the median CRP concentration was within the reference values not indicative of inflammation. The CRKF procedure may be a good solution for the treatment of bone fractures, as damaged associated molecular patterns – HMGB-1 and HSP-70 – did not significantly differ 12-14 hours after the approach was applied as compared to the control group. Moreover, the increase in IL-6 concentration after the CRKF procedure was 1.5-fold to the level before CRKF, while the increase of this marker in response to the distal forearm fracture was 4.3-fold compared to the control group. Based on this data, it appears reasonable to suggest that the CRKF approach caused less damage and inflammatory response in comparison to the response to the fracture itself.

Introduction: Distal radius fracture in pediatric population is the most common sustained injury1. Treatment often is guided by the amount of displacement, with un-displaced fractures requiring only full cast and displaced fractures requiring fixation following reduction with Kirchner Wire (K-wire). Use of a single or double K-wire fixation technique is mostly dependent on the stability of the fracture as well as surgeon preference. Our study aims to evaluate both the Single vs. double K-wire fixation technique for the fixation of Displaced distal radius fracture in children in terms of time of surgery, fracture re-displacement, functional outcome and rate of complications. Materials & Methods: This was a prospective study conducted at The Children Hospital and Institute of Child Health, Lahore between February 1st, 2020 and July 30th 2021. Following approval from the Institutional Ethical committee, 54 pediatric patients presenting to the Emergency and outpatient department with trauma to affected wrist with Displaced Fracture of Distal Radius were admitted and divided into two equal groups. Closed Surgical Fixation following manipulation under anesthesia (MUA) with single and double cross K-wires was performed in each group and Full Cast below elbow was applied for 4 to 6 weeks. Mean radial shortening, angulation and displacement was measured on radiograph pre-operatively, immediate post operatively and at the time of removal of k-wires. Functional outcome was measured post k-wire removal follow up in terms of normal, mildly reduced, moderately reduced and severely reduced. Results: A total of 54 patients were included in the study with the mean age of 9.61(6-14) years, mean time of surgery was 17.26±3.75 minutes for single k-wire and 23.22±3.48 minutes for double k-wire fixation which was significant (p ≤ 0.05). Mean Follow-up was 6.70±0.76 weeks for single k-wire and 6.19±0.48 weeks for double k-wire fixation. There was a statistically significant increase in mean dorsal angulation immediate post-operatively and at the time of k-wire removal (p ≤ 0.05). There was no statistical difference in mean dorsal angulation between the two groups at the time of k-wire removal (p= 0.55). Seven (29.12%) patients of single k-wire developed complications including 3 (11.11%) pin site infection, 1 (1.85%) loss of reduction and 2 (7.41%) wire migration. In contrast to single k-wire fixation, 13 (48.15%) patients developed complications in double k-wire fixation including 7 (29.12%) pin site infection, 1 (1.85%) loss of reduction, 2 (7.41%) neuropraxia and 2 (7.41%) wire migration. In the single k-wire group, 22 (81.48%) patients had normal, 5 (18.52%) had mildly reduced and none had moderately reduced outcome. In double k-wire group, 21 (77.78%) had normal, 5 (.52%) had mildly reduced and 1 (3.70%) had moderately reduced outcome. Conclusion: We concluded that although functional outcome is similar in both groups, single k wire fixation is superior to double k-wire fixation technique in terms of reduced time of surgery and less post-operative complications specially the pin site infection. Key words: Displaced, Distal radius Fracture, K-wire fixation

Additive manufacturing technologies are essential in biomedical modeling and prototyping. Polymer-based bone models are widely used in simulating surgical interventions and procedures. Distal forearm fractures are the most common pediatric fractures, in which the Kirschner wire fixation is the most widely used operative method. However, there is still lingering controversy throughout the published literature regarding the number of wires and sites of insertion. This study aims to critically compare the biomechanical stability of different K-wire fixation techniques. Different osteosyntheses were reconstructed on 189 novel standardized bone models, which were created using 3D printing and molding techniques, using PLA and polyurethane materials, and it has been characterized in terms of mechanical behavior and structure. X-ray imaging has also been performed. The validation of the model was successful: the relative standard deviations (RSD = 100 × SD × mean−1, where RSD is relative standard deviation, SD is the standard deviation) of the mechanical parameters varied between 1.1% (10° torsion; 6.52 Nm ± 0.07 Nm) and 5.3% (5° torsion; 4.33 Nm ± 0.23 Nm). The simulated fractures were fixed using two K-wires inserted from radial and dorsal directions (crossed wire fixation) or both from the radial direction, in parallel (parallel wire fixation). Single-wire fixations with shifted exit points were also included. Additionally, three-point bending tests with dorsal and radial load and torsion tests were performed. We measured the maximum force required for a 5 mm displacement of the probe under dorsal and radial loads (means for crossed wire fixation: 249.5 N and 355.9 N; parallel wire fixation: 246.4 N and 308.3 N; single wire fixation: 115.9 N and 166.5 N). We also measured the torque required for 5° and 10° torsion (which varied between 0.15 Nm for 5° and 0.36 Nm for 10° torsion). The crossed wire fixation provided the most stability during the three-point bending tests. Against torsion, both the crossed and parallel wire fixation were superior to the single-wire fixations. The 3D printed model is found to be a reliable, cost-effective tool that can be used to characterize the different fixation methods, and it can be used in further pre-clinical investigations.

Purpose: Hamate coronal body fracture is a rare injury and often associated with dislocation of the carpometacarpal joint. For preserving the carpometacarpal joint, open reduction and rigid internal fixation is needed to displaced fracture. The purpose of this study was to evaluate the outcome of treating hamate coronal fracture with the screw fixation method through a temporary Kirschner wire (K-wire) fixation hole.Methods: From August 2016 to January 2021, eight patients who had displaced coronal hamate body fractures were enrolled. All patients were performed open reduction and multiple K-wires fixations. After that, the cortical screws were then inserted directly into the holes made by removing the K-wires one by one. The outcome measures were Disabilities of the Arm, Shoulder and Hand (DASH) scores and visual analogue scale (VAS) scores.Results: The average follow-up period was 11.5 months (range, 5–8 months) after surgery, and the bone union was observed at the 8 weeks after surgery. We confirmed that bone union had been completed for all the patients, and functional tests showed that the average DASH score was 3.95 (range, 0–8.3) and VAS score was 0.8 (range, 0–3).Conclusion: In coronal hamate body fractures, open reduction and screw fixation method through temporary K-wire fixation hole is simple and effective treatment technique.
