Abstract
PURPOSE Distal radius fractures involving the volar rim are a subset of unstable and extremely distal fractures involving the volar lunate and/or scaphoid facets. Volar rim fractures (VRF) are challenging to manage and different treatment options have been described. This study aimed to compare outcomes and assess the rates of complications and implant removal for different treatment methods of wrist fractures involving VRF. METHODS A systematic review of studies published in MEDLINE, EMBASE, Web of Science and Cumulative Index to Nursing and Allied Health literature (CINAHL) was conducted to assess the operative outcomes of VRF. Data on patient demographics, implant usage, postoperative outcomes, complications, and implant removal were compiled. RESULTS Twenty-six studies met the inclusion criteria with a total of 617 wrists. The most commonly used implants were 2.4 mm variable-angle volar rim plate (DePuy Synthes) (17.5%), Acu-Loc II (Acumed) (14%) and standalone hook plates (13%). The average outcome measures were Q-DASH (10.9 ± 7), MWS (85.8 ± 7.5), PRWE (15.9 ± 12.1), and DASH (14 ± 8.5). The overall complication rate was 14% (n = 87), with 44% (n = 38) involving flexor tendon problems. The implant removal rate was 22%, with routine removal being performed in 54% and non-routine removal in 46% of cases. CONCLUSION The current treatment of VRF yields favorable functional outcomes across different treatment options. However, these fractures have a high rate of complications and re-interventions, particularly for symptomatic implants. LEVEL OF EVIDENCE Therapeutic IV.

Abstract
BACKGROUND The volar locking plates have been widely used in a variety of distal radius fractures, but they still have several limitations when dealing with small fragments located around the watershed line with widely reported complications. The volar rim fragments play a critical role in radiocarpal joint stability and failing to secure the volar rim fragment usually results in carpal instability, subluxation, or even dislocation. This study investigates clinical outcomes in the use of a novel implant, the Trident distal radial (TDR) locking plate to treat distal radius fracture with the intermedium column edge (lunate fossa volar rim) fragment involvement. METHODS A retrospective study of 25 patients was conducted, all patients had intermedium column fractures with lunate fossa volar rim involvement and treat with the TDR between January 2016 and December 2019. The clinical assessment outcomes included VAS Pain, PRWE, and DASH scores. Objective measurements included ROM of the injured wrist and grip strength. Final radiographs were used to evaluate radial inclination, volar tilt, ulnar variance, and distal radioulnar joint instability. Secondary operations related to hardware complications were also recorded. RESULTS The outcome revealed that the mean VAS Pain Score was 1.3, mean DASH score was 10.5, and mean PRWE score was 9.3. Objective measurements revealed good ROM recovery and an 89% gripping strength recovery compared with contralateral hand. Radiographic measurements revealed good maintenance of volar tilt, radial inclination, and mean ulnar variance. There were no complications related to the implant and all fracture sites were union. CONCLUSION We believe that the TDR provided more stable fixation among distal radial fractures that predominantly involved the intermedial column and volar rim fragment, and allowing early rehabilitation. We could obtain excellent results in the wrist ROM, gripping power, and Pain Score (VAS).

Front Bioeng Biotechnol 2023; 11:1141790. [PMID: 36923459 PMCID: PMC10009098 DOI: 10.3389/fbioe.2023.1141790] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Accepted: 02/20/2023] [Indexed: 03/03/2023] Open
Abstract
Purpose: This study aimed to investigate the biomechanical performance of three Ti6Al4V volar plates with the latest designs using a finite element model. Methods: An AO type 23-A3 distal radius fracture and the models of T plate (2.4 mm LCP Volar Distal Radius Plate), V plate (2.4 mm LCP Two-Column Volar Distal Radius Plate) and π Plate (2.4 mm Volar Rim Distal Radius Plate) (all from Depuy Synthes, West Chester, PA, USA, Ti6Al4V) were built in 3D-matic software. After assembling the internal fixation and fractures, we imported these models into the finite element analysis software (ABAQUS). An axial loading of 100 N was added to the distal end of each model. The displacements of total models and implants, the principal strains and the von Mises stresses in the plates were calculated and compared to capture the biomechanical features of the three plates. Results: The T plate, V plate and π plate represented a model displacement of 0.8414 mm, 1.134 mm and 1.936 mm, respectively. The T plate was with the implant displacement of 0.7576 mm, followed by the V plate (0.8802 mm) and the π plate (1.545 mm). The T plate had the smallest principal strain of 0.23%, the V plate showed an intermediate level of 0.28%, and the π plate had a value of 0.72%. The least peak von Mises stress was observed in the V plate with 263.6MPa, and this value was 435.6 MPa and 1050 MPa in the T plate and π plate, respectively. Conclusion: The biomechanical features of three Ti6Al4V volar locking plates in an AO type 23-A3 fracture were described in our analysis. The T plate and the V plate showed similar biomechanical performance while the π plate represented worse performance than the other two plates.

Abstract
Aim: The volar rim plate is anatomically contoured to provide buttressing of distal radius fragments including the lunate fossa. The low-profile design of the plate minimizes flexor tendon irritation. This study aims to determine the Disabilities of the Arm, Shoulder, and Hand (DASH) score and the presence of flexor tendon irritation at around one-year post operation. Method: Between June 2020 and May 2021, all patients with AO-23B3 and AO-23C (1-3) distal radius fractures who were treated with a volar rim plate fixation were included in this study. At 12 months after surgery, the patients were evaluated utilizing DASH score as a routine as well as evidence of flexor tendon rupture or irritation. Results: Twenty-five patients were finally included in this study. Of these, three required additional dorsal plating for dorsal subluxation, four required fixation of ulna styloid with tension band wiring, and the rest (18) had volar rim plate fixation in isolation. The mean DASH score was 16.3. Two of the patients had flexor tendon irritations; one in the middle finger and another in the ring and little finger. None had flexor tendon rupture. Conclusion: The volar rim plate is designed to tackle complex intra-articular distal fractures which are near the watershed line. There was no evidence of flexor tendon irritation on routine follow-up. The outcome was satisfactory in this small series despite the complexity of the fractures. Evidence of flexor tendon irritation requires prompt attention to enable early implant removal.

Abstract
Background and objectives: Literature does not show any studies regarding plate placement problems in the coronal plane of patients with volar plating due to distal radius fracture diagnosis. We aimed to investigate the functional and laboratory results of the coronal malposition of the volar locking plate in patients with distal radius fracture treated with internal fixation. Methods: In this retrospective study, we included patients who had volar plate fixation, were aged between 18 and 80, had no pathological fracture, had a minimum of six months of follow-up, and had the same rehabilitation protocol. We consider the angle subtended on the coronal axis between the distal radius long axis and the distal radius locking plate as coronal malposition. We named the coronal malposition angle the "AYE Angle." Patients with an AYE angle of over 1 degree were evaluated under group 1. Patients with an AYE angle of 0-1 degrees were evaluated under group 2. Radiological parameters were taken from AP-Lateral X-ray views. Superficial University System of Georgia (USG) examinations were applied to detect tendon problems. The DASH and QUICK-DASH scoring systems were used for clinical evaluation. Grip strength was measured with a dynamometer in all patients. All results were compared between the two groups. Results: Thirteen patients were female and 27 patients were male. Nineteen patients who had coronal malposition were added to group 1, while 21 patients who had no coronal malposition were added to group 2. Fifteen patients had normal USG results in group 2, while 18 patients had edema around the flexor pollicis longus (FPL) tendon as a result of USG in group 1. Statistically, a significant difference was detected between the two groups in terms of the amount of tenosynovitis around FPL (p=0.01). A statistically significant relationship was found between USG grading and malposition grading. The study revealed that a higher rate of USG grade 2 was found in patients with malposition grade 2 (90.9%), while a higher rate of USG grade 1 (50%) was observed in patients with malposition grade 1 (p=0.01). A statistically significant difference was not found between Soong grading and USG in terms of the level of tenosynovitis around the FPL tendon. The amount of tenosynovitis detected around the FPL tendon was 62.5% for Soong and grade 0 level, 60.7% for grade 1 level, and 50% for grade 2 level. There was no statistically significant difference between the two groups in the DASH and QUICK-DASH scoring systems (p=0.96). There was no statistically significant difference between the two groups in the grip strength (p=0.52). Conclusion: Coronal plate position in the treatment of the distal radius fracture is important to avoid potential flexor tendon problems. The volar plate position should be adjusted properly both in the coronal and sagittal axes.

Flexor tendon rupture after volar plating of distal radius fracture: A systematic review of the literature. HAND SURGERY & REHABILITATION 2021; 40:535-546.

Abstract
Flexor tendon rupture after volar plate fixation of distal radius fracture (DRF) is rare. There is no consensus as to how to prevent them. The aim of our study was to identify the pathological mechanisms, and to establish the clinical and epidemiological profile of patients suffering from this complication. We carried out a systematic review using the PubMed, Scopus and Cochrane databases. Studies were included if they described complete or partial flexor tendon rupture following volar plate fixation of DRF. Forty-six 46 were included, for a total of 145 patients were reported: 138 from the literature, and 7 from our personal experience. Etiology was usually mechanical, by impingement with either the plate or protruding screws. Plate impingement was due to positioning beyond the watershed line, consolidation with posterior tilt, plate thickness, or low palmar cortical angle. Mean patient age was 62.4 years (range, 23-89 years). Median postoperative interval was 8 months (range, 3-120 months). Flexor pollicis longus was the most frequently injured tendon. The plate should be positioned proximally to the watershed line if possible, to ensure good initial reduction. Hardware should be removed 4 months after surgery if the plate is causing impingement according to the Soong criteria or if signs of tenosynovitis appear.

Abstract
Background The outcomes for volar locking plate (VLP) and external fixation (EF) in distal radius fracture cases remain controversial. The current study of randomized controlled trials (RCTs) aimed to assess VLP and EF, which might benefit distal radius fracture cases. Methods RCTs comparing VLP and EF in distal radius fracture cases, until 18 March 2020, were systematically reviewed and summarized. The functional and radiographic outcomes, together with complications, for distal radius fracture cases, were evaluated. Results In total, 12 studies comprising 1205 distal radius fracture cases were included. The VLP group had observed lower disability in the arm shoulder and hand score (DASH) at 3rd, 6th, and 12th -month post-operation, with the mean differences (MDs) of − 10.43 (95 % CI = − 15.77 to − 5.08, P < 0.01), − 3.48 (95 % CI = − 6.37 to − 0.59, P = 0.02), and − 4.13 (95 % CI = − 6.94 to − 1.33, P < 0.01), respectively. The VLP group also had lower visual analog scale scores (VAS) compared to the EF group, with MDs of − 0.10 (95 % CI = − 0.18 to − 0.03, P < 0.01) for the former at 6th -month post-operation. Also, the EF group exhibited better grip strength than that in the VLP group, with MD of 12.48 (95 % CI = 7.00–17.95, P < 0.01) at the 3rd month and 4.54 (95 % CI = 0.31–8.76, P = 0.04) at 6th month. No significant differences in radiographic outcomes were observed between the VLP and EF groups (P > 0.05). The VLP group had a lower complication rate than that in the EF group. Conclusions VLP had a lower DASH score and VAS score but with lower grip strength. No significant differences in radiographic outcomes were observed. VLP had a lower complication rate than that of EF. Supplementary Information The online version contains supplementary material available at 10.1186/s12891-021-04312-7.

Comparison of clinical outcomes with and without volar lunate facet fragments in dorsal displaced distal radius fractures. SICOT J 2021; 7:1.

Abstract
Introduction: Although many clinical studies about distal radius fracture (DRF) accompanied by volar lunate facet fragments (VLFF) have recently been reported, none focus on the direction of displacement of distal fragments. Many previous cases with difficulty in treating DRF with VLFF were volar-displaced fractures. Thus, the postoperative risk for re-displacement is different between volar- and dorsal-displaced fractures with VLFF. The aim of this study is to compare the outcome of dorsal-displaced fractures treated using proximal volar locking plates (PVLP) between those with VLFF and those without, in order to reconsider the indications of distal volar locking plates (DVLP) and investigate the possibility of treating dorsal-displaced DRF with VLFF using PVLP. Methods: The subjects were 122 patients with dorsal-displaced DRFs treated using PVLP (42 males and 80 females, mean age: 59.2 years old). The patients were divided into 13 patients with VLFF group and 109 patients without VLFF group, and the clinical outcomes at 12 months after surgery were compared. Results: No significant difference was noted on any evaluation between the groups. In addition, no postoperative re-displacement of VLFF was observed and bone union was confirmed. Furthermore, no osteoarthritic change was noted in all patients. Conclusions: We confirmed that surgical treatment for dorsal-displaced DRF using PVLP is possible even in cases of DRF with VLFF. In addition, DVLP is an implant with a high complication risk; therefore, it may be necessary to reconsider the use of DVLP for dorsal-displaced DRF with VLFF treatable by PVLP.

Abstract
BACKGROUND Treatment of distal radius fractures has seen a paradigm shift since the use of volar locking plates became popular. However, there is a subset of fractures, which includes extreme distal volar rim fractures, that is often not amenable to fixation by volar locking plates as there is insufficient bone mass to put screws. These fractures as such are quite rare but carry a huge morbidity due to frequent lack of anatomical reduction and fixation. A number of different techniques like hook plates, specially designed distal volar locking plates and loop wire techniques have been described for these fractures, but they have been found to be less helpful when the fracture fragments are very small. METHODS Herein, we describe our experience on 6 patients, using a novel surgical technique for fixation of distal radius volar rim fractures which works equally well even when the fragments are quite small (2-3 mm). The technique uses low cost and readily available implants (K wire and conventional volar locking plate) without the need of any special implants. RESULTS The total of 6 cases of distal radius volar rim fractures (AO/OTA Type B3 = 4, Type C1 = 2) were operated. The mean age was 50.83 years (range: 31-72). The mean follow-up duration was 43.3 months (range: 26-66). The mean size of the volar fragment was 3.66 mm (range: 2-5). The mean pronation and supination were 72.5° (60-80) and 74.2° (60-85). The main flexion and extension were 52.5° (40-75) and 58.3° (50-80) respectively. The mean grip strength was 19.8 kg (4-38) and it was mean 79.3% (40-130%) compared to uninjured side. The mean PRWE score was 12.3 (2-31). One patient developed symptoms of Complex Regional Pain syndrome 1 (CRPS 1) which resolved with conservative management and no other complications were noted. CONCLUSION Our technique offers an indigenous, cost-effective way for fixation of extreme volar rim fracture fragments which can be easily adopted and used by surgeons in developing countries.

Abstract
Marginal fracture types of the distal radius may require volar plate positioning distal to the watershed line. Subsequently, plate prominence with direct friction with the flexor tendons occurs which is associated with flexor tendon pathology. Standard plate removal can be proposed. This cohort study examined clinical outcome, patient satisfaction and ultrasonographical assessment of the relation of the flexor pollicis longus (FPL) and the volar rim after standard plate removal. Twenty patients with volar plate prominence after osteosynthesis for distal radius fractures were included. Plate removal was performed at least 4 months after initial surgery. The mean age was 60 years (range 39-84). The average delay from hardware removal to assessment was 2.9 years (range 1.0-5.0 years). Mean flexion, extension and radial deviation were significantly decreased (p < 0.05) compared to the contralateral side, while ulnar deviation, pro- and supination and grip strength were not. Mean QuickDASH score was 21.5. 85% of patients described their result as good to excellent. 80% would undergo the intervention again. During ultrasonography, distance from FPL to volar rim remained significantly decreased compared to the uninjured side in neutral and flexed position (p < 0.05) despite plate removal. The largest distance between the FPL and the volar cortical bone, which is mainly occupied by the pronator quadratus, did not differ. In this study, the range of motion and FPL distance to the distal radius normalized only partially compared to the uninjured wrist after standard plate removal.

A Loop-Wiring Technique for Volarly Displaced Distal Radius Fractures With Small Thin Volar Marginal Fragments. J Hand Surg Am 2020; 45:261.e1-261.e7. [PMID: 31859052 DOI: 10.1016/j.jhsa.2019.10.022] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2019] [Revised: 06/29/2019] [Accepted: 10/09/2019] [Indexed: 02/02/2023]
Abstract
Volarly displaced distal radius fractures (VD-DRFs) with small thin volar marginal fragments (VMFs) are challenging to treat with conventional volar locking plates (VLPs) alone. Several alternative surgical options have been reported to treat these fractures, including wire-loop fixation, spring-wire fixation, hook plates, headless compression screws, and tension-band wiring, but the optimal method is yet to be determined. We have devised a surgical treatment for these fractures, entitled the "loop-wiring method" in which VMFs are anatomically reduced and 2 0.043-inch K-wires are drilled through the volar tip of the fragment and introduced into the dorsal cortex. Two bone tunnels are then made with a 0.039-inch K-wire, before a 0.028-inch soft wire is passed from the volar to the dorsal side and tightened over the dorsal cortex. After a fracture at the volar rim, even if properly reduced, compression stress is continuously generated on the volar cortical side of the fracture site and tension is generated on the articular side, which leads to VMF displacement, articular surface widening, and carpal subluxation. The loop-wiring technique applies compressive pressure securely to the articular side of the fracture site as well as to the whole fracture site and may be advantageous in terms of secure fixation of small thin volar marginal fragments, stability of the carpus, and bone healing.

Wang J, Lu Y, Cui Y, Wei X, Sun J. Is volar locking plate superior to external fixation for distal radius fractures? A comprehensive meta-analysis. ACTA ORTHOPAEDICA ET TRAUMATOLOGICA TURCICA 2018; 52:334-342. [PMID: 30497657 PMCID: PMC6204453 DOI: 10.1016/j.aott.2018.06.001] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/06/2018] [Revised: 05/01/2018] [Accepted: 06/12/2018] [Indexed: 11/23/2022]
Abstract
Objective The aim of this meta-analysis of randomized controlled trials (RCT) and retrospective cohort studies (CS) regarding the use of volar locking plate (VLP) and external fixation (EF) in distal radius fractures was to determine whether there was any evidence that one treatment was superior to the other. Methods The meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Electrical databases (PubMed, EMBASE and the Cochrane library) were retrieved to find RCTs and CSs met the eligibility criteria. Two reviewers screened the studies, extracted the data and evaluated the methodological quality, and performed data analysis with RevMan 5.1. The publication bias was test by Stata 14.0. The Begg's and Egger's test were performed by Stata 14.0. The quality of evidence was graded according to the criteria of GRADE. We ultimately included ten RCTs and eleven CSs. Results A total of 1590 subjects were reported. Publication bias was detected by funnel plot in RCTs. VLP could provide better results such as DASH scores (RCT: MD = −6.12, 95%CI = −12.07–0.17; CS: MD = −6.43, 95%CI = −12.53–0.3), ulnar variance (RCT: MD = −0.81, 95%CI = −1.25–0.37) and infection rate (RCT: RR = 0.25, 95%CI = 0.10–0.65; CS: RR = 0.15, 95%CI = 0.06–0.40). There were no significant differences for G-W scores, VAS and grip strength between the VLP group and EF group. There was significantly greater loss of volar tilt (P = 0.01) and radial inclination (P = 0.02) in patients receiving EF, basing on the CSs. Conclusions VLP could provide better results, such as DASH scores, ulnar variance, volar tilt, radial inclination and infection rate. The use of VLP appear to be associated with better results of ROM (flexion, pronation, supination and radial deviation), radiographic parameters (volar tilt and radial inclination) and lower total complication rate and CRPS rate in CSs. Level of evidence Level 1, Therapeutic study.

Titanium Fiber Plates for Bone Tissue Repair. ADVANCED MATERIALS (DEERFIELD BEACH, FLA.) 2018; 30:1703608.

Abstract
Titanium plates are widely used in clinical settings because of their high bone affinity. However, owing to their high elastic modulus, these plates are not suitable for bone repair since their proximity to the bone surface for prolonged periods can cause stress shielding, leading to bone embrittlement. In contrast, titanium fiber plates prepared by molding titanium fibers into plates by simultaneously applying compression and shear stress at normal room temperature can have an elastic modulus similar to that of bone cortex, and stress shielding will not occur even when the plate lies flush against the bone's surface. Titanium fibers can form a porous structure suitable for cell adhesion and as a bone repair scaffold. A titanium fiber plate is combined with osteoblasts and shown that the titanium fiber plate is better able to facilitate bone tissue repair than the conventional titanium plate when implanted in rat bone defects. Capable of being used in close contact with bone for a long time, and even capable of promoting bone repair, titanium fiber plates have a wide range of applications, and are expected to make great contributions to clinical management of increasing bone diseases, including bone fracture repair and bone regenerative medicine.
