Anterior locking plate fixation versus cast immobilization for acceptably reduced extra- articular distal radial fractures: long-term follow-up of a randomized controlled trial.

This study reports the long-term results of a randomized controlled trial comparing anterior locking plate fixation with cast immobilization for extra-articular distal radial fractures. After 5.3 years of follow-up, no clinically relevant functional differences were found.

Comparison of extra-articular radiographic parameters of distal radius fractures on plain radiographs and CT scans.

The aim of this study was to compare extra-articular radiographic parameters of distal radial fractures measured on plain radiographs and CT scans. Two researchers independently measured four extra-articular radiographic parameters (dorsal tilt, carpal alignment, radial inclination and ulnar variance) on both radiographs and CT scans in 85 patients. Inter-observer reliability for both techniques was assessed, along with the agreement between CT scans and radiographs using the intraclass correlation coefficient and Bland-Altman plots. The results showed that dorsal tilt, carpal alignment, radial inclination and ulnar variance can be measured reliably on both radiographs and CT scans. At a patient level, carpal alignment, radial inclination and ulnar variance CT scan measurements are an acceptable alternative to plain radiograph measurements in the vast majority of patients. In contrast, dorsal tilt CT scan measurements are not comparable with radiographs in 40% of the cases. Therefore, caution should be taken in measuring dorsal tilt on CT scans.

Patient-Related Outcomes of Arthroscopic Resection of Ganglion Cysts of the Wrist.

Background Ganglion cysts of the wrist can cause pain and loss of functionality. No consensus exist on optimal treatment. Arthroscopic resection shows promising results but is poorly studied. Furthermore, only few studies have used patient-related outcomes to evaluate arthroscopic treatment. Purpose The purpose of this study was to assess patient-related outcomes following arthroscopic resection of wrist ganglion cysts. Patients and Methods This was a retrospective study of all consecutive patients that underwent arthroscopic resection of a dorsal or volar wrist ganglion. Minimum follow-up was 6 months. The primary outcome was the patient-rated wrist evaluation (PRWE). Secondary outcomes were recurrence rate and complications. Results A total of 53 patients were included with a mean follow-up of 13 months (interquartile range: 6-23 months). Twenty-six patients (49%) presented with a recurrence following prior treatment. Mean PRWE was 13 (standard deviation [SD] = 1.8), with no difference between patients with dorsal or volar ganglion cysts. There were five recurrences (9%), of which three occurred in the first five patients who were operated. There were three patients with complications (6%), consisting of neuropraxia, extensor carpi ulnaris tendinitis, and painful scar tissue. Conclusion Arthroscopic resection results in good patient-related outcome and low complication and recurrence rates when performed by an experienced surgeon. Recurrence and complication rates are similar to arthroscopic resections described in literature and superior to open resection and needle aspiration. Well-designed randomized clinical trials will be necessary to confirm these findings. Level of Evidence This is a level IV, retrospective study.

Diagnosis of dorsal screw penetration after volar plating of a distal radial fracture.

AIMS: The aim of this study was to investigate whether intraoperative 3D fluoroscopic imaging outperforms dorsal tangential views in the detection of dorsal cortex screw penetration after volar plating of an intra-articular distal radial fracture, as identified on postoperative CT imaging. METHODS: A total of 165 prospectively enrolled patients who underwent volar plating for an intra-articular distal radial fracture were retrospectively evaluated to study three intraoperative imaging protocols: 1) standard 2D fluoroscopic imaging with anteroposterior (AP) and elevated lateral images (n = 55); 2) 2D fluoroscopic imaging with AP, lateral, and dorsal tangential views images (n = 50); and 3) 3D fluoroscopy (n = 60). Multiplanar reconstructions of postoperative CT scans served as the reference standard. RESULTS: In order to detect dorsal screw penetration, the sensitivity of dorsal tangential views was 39% with a negative predictive value (NPV) of 91% and an accuracy of 91%; compared with a sensitivity of 25% for 3D fluoroscopy with a NPV of 93% and an accuracy of 93%. On the postoperative CT scans, we found penetrating screws in: 1) 40% of patients in the 2D fluoroscopy group; 2) in 32% of those in the 2D fluoroscopy group with AP, lateral, and dorsal tangential views; and 3) in 25% of patients in the 3D fluoroscopy group. In all three groups, the second compartment was prone to penetration, while the postoperative incidence decreased when more advanced imaging was used. There were no penetrating screws in the third compartment (extensor pollicis longus groove) in the 3D fluoroscopy groups, and one in the dorsal tangential views group. CONCLUSION: Advanced intraoperative imaging helps to identify screws which have penetrated the dorsal compartments of the wrist. However, based on diagnostic performance characteristics, one cannot conclude that 3D fluoroscopy outperforms dorsal tangential views when used for this purpose. Dorsal tangential views are sufficiently accurate to detect dorsal screw penetration, and arguably more efficacious than 3D fluoroscopy. Cite this article: Bone Joint J 2020;102-B(7):874-880.

Functional Outcome following Headless Compression Screw Fixation for Hamate Fractures.

Hamate fractures can be treated nonoperatively, with the percutaneous Kirschner wire (K-wire) fixation, or with excision of a fractured hook of the hamate. Screw fixation is less popular owing to the risk of iatrogenic ulnar nerve injury. The aim of this study was to present the functional results of patients with hamate fractures treated with headless compression screws (HCS). The primary outcome was the Michigan Hand Outcome Questionnaire (MHOQ) after at least 4 months of follow-up. Nine patients were included in this retrospective cohort study. A median MHOQ total score of 67% was reported (interquartile range [IQR]: 44-76). No complications were found during follow-up. HCS fixation is a safe alternative to treat hamate fractures with good functional outcome. This is a Level IV study.

Patient-Reported Outcomes following Arthroscopic Triangular Fibrocartilage Complex Repair.

Background Triangular fibrocartilage complex (TFCC) injury is a common cause of ulnar-sided wrist pain, which may lead to serious physical impairments. Arthroscopic repair has benefits such as less soft tissue damage, greater surgical accuracy, and may lead to faster recovery than open repair. Objective The purpose of this study was to determine the functional outcome of patients with symptomatic TFCC injuries treated with arthroscopic debridement or repair. Patients and Methods A retrospective study of all consecutive patients with a TFCC injury treated arthroscopically was conducted. The primary outcome was the patient-rated wrist evaluation (PRWE) score. Secondary outcomes were, pain, operative findings, complications, and additional treatment. Results A total of 51 patients with a median follow-up of 16.5 months (interquartile range [IQR]: 13-25) were included. Injuries were treated with TFCC debridement ( n = 25), TFCC ligament to capsule suturing ( n = 10), TFCC debridement and ligament to capsule suturing ( n = 7), TFCC debridement and synovectomy ( n = 5), and TFCC foveal reinsertion with a suture anchor ( n = 4). The median PRWE was 19.5 (IQR: 6-49). Complications occurred in three patients and in nine patients additional surgery was performed. Conclusion Arthroscopic treatment of TFCC lesions leads to satisfactory functional outcomes. Level of Evidence This is a Level IV study.

Arthroscopic debridement does not enhance surgical treatment of intra-articular distal radius fractures: a randomized controlled trial.

The aim of this study was to determine the difference in functional outcomes after open reduction and internal fixation (ORIF) with and without arthroscopic debridement in adults with displaced intra-articular distal radius fractures. In this multicentre trial, 50 patients were randomized between ORIF with or without arthroscopic debridement. The primary outcome measure was the Patient-Rated Wrist Evaluation (PRWE) score. Secondary outcome measures were Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, pain scores, range of wrist motion, grip strength, and complications. Median PRWE was worse for the intervention group at 3 months and was equal for both groups at 12 months. The secondary outcome measures did not show consistent patterns of differences at different time-points of follow-up. We conclude that patients treated with additional arthroscopy to remove intra-articular hematoma and debris did not have better outcomes than those treated with ORIF alone. We therefore do not recommend arthroscopy for removal of hematoma and debris when surgically fixing distal radius fractures. Level of evidence: I.

Plate Fixation for Unstable Displaced Distal Radius Fractures in Children.

Background Distal radius fractures in children are normally treated by plaster immobilization. For displaced unstable distal radius fractures, closed reduction and Kirschner wire (k-wire) fixation can be performed. Disadvantages of k-wire fixation are the need for postoperative plaster treatment for several weeks, which may induce stiffness, and the risks of complications such as tendon irritation and pin-track infections. More invasive volar plate fixation is less popular, although this allows for direct mobilization and enhances anatomical reduction. Purpose To present the functional outcomes of pediatric patients treated with volar plate fixation for unstable displaced distal radius fractures. Patients and Methods A retrospective cohort study of all consecutive pediatric patients between September 2010 and July 2017 was performed. A total of 26 patients with a median age of 12.5 years were included. The primary objective was functional outcome determined by the Patient-Rated Wrist Evaluation (PRWE) questionnaire. Secondary objectives were range of motion, grip strength, radiological parameters, complications, and incidence of plate removal. Results Median PRWE score was 3 after a median follow-up of 29 months. Range of motion and grip strength did not differ significantly between the injured and uninjured wrists. No wound infections were found. Plate removal was performed in 15 patients (58%). Conclusion Volar plate fixation for unstable displaced distal radius fractures in children provides good functional and radiological outcomes with minor complications. Level of evidence This is a Level IV cohort study.

Operative Treatment of Intra-Articular Distal Radius Fractures With versus Without Arthroscopy: study protocol for a randomised controlled trial.

BACKGROUND: In the past several years, an increase in open reduction and internal fixation (ORIF) for intra-articular distal radius fractures has been observed. This technique leads to a quicker recovery of function compared to non-operative treatment. However, some patients continue to have a painful and stiff wrist postoperatively. Arthroscopically assisted removal of intra-articular fracture haematoma and debris may improve the functional outcomes following operative treatment of intra-articular distal radius fractures. The purpose of this randomised controlled trial is to determine the difference in functional outcome, assessed with the Patient-Rated Wrist Evaluation (PRWE) score, after ORIF with and without an additional wrist arthroscopy in adult patients with displaced complete articular distal radius fractures. METHODS: In this multicentre trial, adult patients with a displaced complete articular distal radius fracture are randomised between ORIF with an additional wrist arthroscopy to remove fracture haematoma and debris (intervention group) and conventional fluoroscopic-assisted ORIF (control group). The primary outcome is functional outcome assessed with the PRWE score after three months. Secondary outcomes are wrist function assessed with the Disability of the Arm, Shoulder and Hand (DASH) score, postoperative pain, range of motion, grip strength, complications and cost-effectiveness. Additionally, in the intervention group, the quality of reduction, associated ligamentous injuries and cartilage damage will be assessed. A total of 50 patients will be included in this study. DISCUSSION: Although ORIF of intra-articular distal radius fractures leads to a quicker resume of function compared to non-operative treatment, some patients continue to have a painful and stiff wrist postoperatively. We hypothesise that, due to the removal of fracture haematoma and debris by an additional arthroscopy, functional outcomes will be better compared to the non-arthroscopically treated group.

Relationship between plate removal and Soong grading following surgery for fractured distal radius.

The aim of this study was to determine the relationship between volar plate removal and the Soong classification following fixation for fractured distal radius. In this retrospective cohort study, all consecutive patients who had volar plate fixation for a distal radius fracture in 2011-2015 were reviewed. Differences in Soong classification between patients who had plate removal and those who did not were analysed. The total incidence of plate removal was calculated and the indications analysed. A total of 323 patients were included. The incidence of plate removal in all patients was 17%. Soong classification was significantly higher in patients who had plate removal compared with those who did not. For patients with plate placement classified as Soong grade 2, the incidence of plate removal was almost six times higher than those classified as Soong grade 0. The relationship between volar plate removal and a higher Soong grading stresses the importance of accurate plate positioning. LEVEL OF EVIDENCE: IV.
