Abstract Background Purpose was to correlate flexor pollicis longus tendon (FPL) attrition using Ultrasonography with plate position on radiographs following volar locked compression plate fixation (LCP) in patients who have undergone pronator quadratus (PQ) repair for distal radius fractures. Methods Status of flexor pollicis longus tendon was analyzed by ultrasonography in patients who underwent volar locked compression plating with pronator quadratus repair at a minimum of one year follow up. Soong’s criteria was used to assess the plate position and then correlated the ultrasonography findings of flexor pollicis longus. Results There were 33 patients included in our study, of which 15 belonged to Soong’s grade zero, 10 were grade one and eight were grade two. Flexor pollicis longus attrition was noted in all cases with grade two plating. Conclusion Pronator quadratus repair may not prevent attritional changes in higher grades of Soong’s, hence follow up may be required in these patients to identify attritional changes and early implant removal to prevent complications.

Background: Previous work evaluating the pronator quadratus (PQ) muscle following volar plate fixation (VPF) of distal radius fractures (DRF) suggests that PQ repair often fails in the postoperative period. The purpose of this investigation was to assess PQ repair integrity following VPF of DRF using dynamic musculoskeletal ultrasonography. Methods: Twenty adult patients who underwent VPF of DRF with repair of the PQ with a minimum follow-up of 3 months underwent bilateral dynamic wrist ultrasonography. The integrity of the PQ repair, wrist range of motion (ROM) and strength, and functional outcome scores were assessed. Results: Mean patient age at the time of surgery was 59 ± 14 years, and 50% underwent VPF of their dominant wrist. Patients were evaluated at a mean 9 ± 4 months after VPF. All patients had an intact PQ repair. The volar plate was completely covered by the PQ in 55% of patients and was associated with a larger PQ when compared to patients with an incompletely covered volar plate ( P = .026). The flexor pollicis longus tendon was in contact with the volar plate in 20% of patients, with those patients demonstrating a trend toward significantly increased wrist flexion ( P = .053). No difference in ROM, strength, or outcome scores was noted among wrists with completely or incompletely covered volar plates. Conclusions: The PQ demonstrates substantial durability after repair following VPF. Wrist ROM, strength, and functional outcomes are similar in wrists in which the volar plate is completely or incompletely covered by the repaired PQ.

Abstract Introduction Distal radius fractures are common and trends for fixation have changed with increased use of volar locking plates in recent time. A meta-analysis will summarise the best evidence for treatment. Method A systematic review was conducted using PRISMA methodology to identify studies that reported clinical and/or radiological outcomes in patients with AO type C distal radius fractures when treated with external fixation versus ORIF. Results 10 randomised trials were included in this review, reporting on 967 patients. Clinical outcomes are in favour of volar plating at 3 months post-operation, but no difference between the two groups is seen at 6 or 12 months. Analysis of complication rates shows a minute increase in risk-ratio for volar plating versus external fixation. Subgroup analysis showed significantly higher re-operations after plate fixation and significantly higher infection after external fixation. Conclusions Internal fixation of complex distal radius fractures confers an improved clinical outcome at early follow up only and a minimally increased risk of complications. The improved grip strength with volar plating is only superior at early follow up and no long-term superiority is seen with either intervention. The type of surgery in this injury type therefore remains at the surgeon’s consideration on a case-by-case basis.

Abstract Background The aim of this study is to evaluate the frequency of flexor pollicis longus (FPL) tendon rupture and factors leading to this rupture during the follow-up of patients who underwent volar plate fixation because of distal radius fracture. Patients and Methods A total of 109 distal radius fractures of 102 patients treated with volar plate fixation and periodically followed up for at least 1 year between January 2013 and May 2018 were evaluated. Fractures were categorized according to the AO Foundation/Orthopaedic Trauma Association (AO/OTA) Fracture-Dislocation Classification and Soong's grading was used for classifying volar plate position. All patients operated were inquired retrospectively in terms of flexor tendon rupture. Results Gender distribution revealed 45 females and 57 males. Mean age was 47.9 (range: 17–88) years. Mean period of follow-up was 27 months. Distribution of fractures in accordance with the AO/OTA distal radius classification was 6, 8, 7, 12, 24, 33, 11, and 8 patients with types A2, A3, B1, B2, B3, C1, C2, and C3, respectively. When volar plate positions were analyzed with Soong's classification, it revealed that 79 (72.4%), 23 (21.1%), and 7 (6.5%) plates were grade 0, 1, and 2, respectively. In total, evaluating the three patients with FPL rupture, it revealed that the volar plate was positioned distally during fixation because the fracture line had advanced to the distal of the watershed line, the distal portion of the plate had lost complete connection with the bone, and at this portion, it was observed that the pronator quadratus muscle was not covering the plate entirely (Soong's classification grade 2). Patients did not have additional flexor tendon injury. Conclusion FPL tendon rupture is a rare but serious complication of volar plate fixation performed for distal radius fractures. We believe that appropriate choice of implant and careful surgical technique, along with the close follow-up of patients, with Soong's classification grade-2 volar positions would help in preventing this complication. Level of Evidence This is a Level 3a, differential diagnosis/symptom prevalence study.

We evaluated the presence of "tendon irritation" of flexor pollicis longus (FPL) for cases of distal radius fracture treated with volar plates to prevent FPL tendon rupture. This report details cases of 24 patients. The presence of pain or a sense of incompatibility and subdermal crepitus around the wrist with an active thumb motion were defined as symptoms of FPL tendon irritation. Twelve of 24 patients complained of FPL tendon irritation. The plates were removed in nine of these 12 patients, while tendon injury was found in three cases. The other 12 patients did not complain of FPL tendon irritation. Four of these 12 patients underwent plate removal, and tendon injury was not detected. The results of this study indicate that FPL tendon irritation is likely to appear before tendon rupture. Therefore, FPL tendon rupture might be prevented by plate removal in patients who complained of tendon irritation.

Abstract Background: Although distal radius fractures (DRFs) are clinically common, DRFs accompanied by dorsally displaced free fragments beyond the watershed line are much less so. At present, it is very difficult to fix and stabilize the displaced free fragments far away from the watershed line with a plate. Our aim was to investigate the clinical effect of DRFs with distally displaced dorsal free mass treated with distal volaris radius (DVR) combined with turning of the radius via the distal palmar approach. Methods: From 2015 to 2019, 25 patients with distal radius fractures associated with dorsally displaced free fragments beyond the watershed line were selected and treated with distal volaris radius (DVR) combined with turning of the radius via the distal palmar approach. This study involved 14 males and 11 females, with an average age of 34.5 years (ranging from 21 to 50 years). The mean follow-up period was 16.5 months (ranging from 12 to 22 months). The dorsal displacement of the free fragments was analyzed by X-ray and three-dimensional computed tomography, allowing characterization of postoperative recovery effects by radial height, volar tilt and radial inclination. For the follow-up, we evaluated effects of the surgery by analyzing range of motion (ROM); Modified Mayo Wrist Score (MMWS); and Disabilities of Arm, Shoulder and Hand (DASH) score. Postoperative wound recovery and complications were also monitored to evaluate the clinical therapeutic effects of the surgical procedures. Results: X-ray showed that all patients showed reduced fractures, well-healed wounds and recovered function with no obvious complications. Based on the follow-up, patients had a mean radial height of 10.5mm (ranging from 8.1 to 12.6 mm), mean MMWS of 78.8° (ranging from 61 to 90°), mean DASH score of 16.25 (ranging from 11 to 21), mean ROM for volar flexion of 76.5° (ranging from 62 to 81°), mean ROM for dorsiflexion of 77.1° (ranging from 59 to 83) and mean VAS score of 1.4 (ranging from 1 to 3). Conclusion: Treatment of distal radius fractures with accompanying dorsally displaced free fragments beyond the watershed line with turning of the radius and the DVR plate system via the distal palmar approach is effective and has no obvious complications.
