Background: This study compares the effectiveness of a peripheral capsular repair with a knotless arthroscopic transosseous ulnar tunnel repair (TR) in restoring distal radioulnar joint (DRUJ) stability and stiffness in the setting of a massive triangular fibrocartilage complex (TFCC) tear. Methods: Eight matched pairs of fresh-frozen cadaveric forearms were tested. Each forearm was tested in supination and pronation using 3-dimensional (3D) optical tracking devices prior to any intervention. Each specimen then underwent a diagnostic wrist arthroscopy and sectioning of the TFCC’s deep and superficial fibers. All specimens were then retested to assess instability secondary to the tear. The TFCC was repaired with either a peripheral capsular repair (CR) using three 2-0 polydioxanone sutures or a transosseous ulnar TR using a 2-0 FiberWire, and then retested (statistical significance; P < .05). Results: After TFCC arthroscopic sectioning, all specimens were unstable with a significant increase in translation and a significant decrease in stiffness. TFCC repair with TR resulted in displacement and stiffness similar to the native tissue. CR specimens were found to have significantly greater displacement and significantly decreased stiffness compared with the intact state. Conclusions: Arthroscopic sectioning of the TFCC resulted in DRUJ instability, as measured by stiffness and ulnar translation. TR effectively restored DRUJ stability and demonstrated no significant difference in postoperative stiffness or maximal displacement when compared with the intact specimen in pronation and supination. This study provides biomechanical evidence that an arthroscopic ulnar tunnel technique can restore stability to the DRUJ after a massive TFCC tear.

Significant Difference

Reconstruction of C2 after tumor destruction and resection remains a significant challenge. Most constructs utilize a strutgraft with plate or screw fixation. A novel C2 prosthesis combining a titanium mesh cage with bilateral C1 shelves and a T-plate has been used successfully in 18 patients. Supplemental posterior instrumentation includes C0-C3 or C1-C3. Biomechanical comparisons of this C2 prosthesis with traditional fixation options have not been reported. Five fresh-frozen human cadaveric cervical spines (C0-C5) were tested intact. Next, the C2 prosthesis, and strut graft and anterior plate constructs were tested with occiput-C3 and C1-C3 posterior fixation. Pure moment loads (up to 1.5 N-m) were applied in flexion and extension, lateral bending, and axial rotation. C1-C3 motion was evaluated using 3 camera motion analysis. Statistical significance was evaluated using one-way repeated measures ANOVA with Student-Newman-Keuls post hoc pairwise comparisons. All constructs provided a statistically significant decrease in motion in this C2 corpectomy model as compared to the intact condition. There was no significant difference in C1-C3 motion between the 4 constructs, regardless of whether the occiput was included in the fixation. Under these loading conditions, both the C2 prostheisis and strut-graft-plate constructs provided initial C1-C3 stability beyond that of the intact specimen. The occiput does not need to be included in the posterior instrumentation.

Sixty-one wrists in 61 patients with osteoarthritis of the distal radioulnar joint treated by three consecutive procedures (20 Darrach, 25 Sauvé-Kapandji and 16 hemiresection-interposition arthroplastic procedures) were retrospectively evaluated. We preferred to perform Darrach's procedure in even the early stages of osteoarthritis of the distal radioulnar joint prior to introduction of Sauvé-Kapandji and hemirestion-interposition arthroplastic procedures. Subsequently the hemirestion-interposition arthroplasty was indicated when the triangular fibrocartilage cartilage was intact or could be reconstructed and the Sauvé-Kapandji when the triangular fibrocartilage complex could not be reconstructed or there was positive ulnar variance of more than 5 mm even though the triangular fibrocartilage complex was functional. Patient's age at operation averaged 59.8 years. There were 36 men and 25 women. There were 38 primary and 23 secondary osteoarthritis cases. Post-operative pain, range of motion, grip strength, return to work status; and radiographic results were evaluated. At the five- to 14-year (average, ten years) follow-up evaluation, relief of pain from Darrach procedure was inferior to the Sauvé-Kapandji procedure and hemiresection-interposition arthroplasty although this was not statistically significant. After both the Sauvé-Kapandji procedure and hemiresection-inteposition arthroplasty, post-operative improvements in flexion and extension of the wrist had statistical significance. Post-operative improvements in pronation and supination of the forearm showed statistical significances after all procedures. Improvements of post-operative grip strength and return to an original job in the Sauvé-Kapandji procedure and hemiresection-interposition arthroplasty were statistically superior to those with a Darrach's procedure. There were many post-operative complications following the Darrach's procedure. Darrach's procedure is better indicated for severe osteoarthritic changes of the distal radioulnar joint in elderly patients. We believe the operative indications between the Sauvé-Kapandji procedure and hemiresection-interposition arthroplasty are best determined prior to surgery by the existence and status of the triangular fibrocartilage complex and the amount of the positive ulnar variance.

A Prospective Study

Our purpose was to determine the correlation of initial radiographic parameters of a distal radius fracture with an injury of the triangular fibrocartilage complex. In a prospective study, 85 patients with surgically treated distal radius fractures were included. Wrist arthroscopy was used to identify and classify triangular fibrocartilage complex lesions. The initial radial length and angulation, dorsal angulation, ulnar variance and distal radioulnar distance were measured. Wrist arthroscopy identified a triangular fibrocartilage complex lesion in 45 patients. Statistical analysis did not identify a correlation with any single radiographic parameter of the distal radius fractures with the associated triangular fibrocartilage complex injuries. The initial radiograph of a distal radius fracture does not predict a triangular fibrocartilage complex injury. Level of evidence: III

A total of 20 patients scheduled for wrist arthroscopy, all with clinical signs of rupture to the triangular fibrocartilage complex and distal radioulnar joint instability, were tested pre-operatively by an independent observer for strength of forearm rotation. During surgery, the intra-articular pathology was documented by photography and also subsequently individually analysed by another independent hand surgeon. Arthroscopy revealed a type 1-B injury to the triangular fibrocartilage complex in 18 of 20 patients. Inter-rater reliability between the operating surgeon and the independent reviewer showed absolute agreement in all but one patient (95%) in terms of the injury to the triangular fibrocartilage complex and its classification. The average pre-operative torque strength was 71% of the strength of the non-injured contralateral side in pronation and supination. Distal radioulnar joint instability with an arthroscopically verified injury to the triangular fibrocartilage complex is associated with a significant loss of both pronation and supination torque. Level of evidence: Case series, Level IV.

Abstract Introduction Peripheral injuries of the triangular fibrocartilage complex (TFCC) can produce pain and instability of the distal radioulnar joint (DRUJ). There are several techniques for the reconstruction of the TFCC. The aim of the present paper was to summarize the tendon plasties of the DRUJ ligaments for the anatomic reconstruction of TFCC, to analyze the surgical techniques, and to evaluate their outcomes. Methods In order to perform a systematic review, we searched in the literature the terms DRUJ instability OR chronic distal radioulnar joint instability OR distal radioulnar tendon plasty. Results In total, 11 articles with level of evidence IV (case series) were retrieved. Most studies achieved good results, with recovery of wrist stability, improvement of the pain, and increase in grip strength in the functionality tests. In the historical evolution of the published series, wrist surgeons tried to perform a more anatomical plasty, with a more stable fixation and less invasive techniques. Conclusion The Adams procedure continues to be a valid and reproducible technique for the treatment of chronic DRUJ instability. If wrist arthroscopy and implants are available and surgeons have been technically trained, the authors recommend an arthroscopy-assisted technique, or, if possible, an all-arthroscopic TFCC reconstruction with implant fixation of the plasty in its anatomical points of insertion. Comparative studies between open and arthroscopic TFCC reconstruction techniques are needed.

Background Congenital abnormalities of the triangular fibrocartilage complex (TFCC) are rare and could be mistaken for a traumatic lesion. It is important to recognize these anatomical variations and to realize they do not always require treatment. Case Description An incidental finding of an atraumatic bucket handle abnormality of the TFCC in a 15-year-old male, who was treated arthroscopically for dorsal wrist pain. This structure was resected, thus obtaining a normal looking peripheral TFCC. Literature Review Literature regarding congenital abnormalities of the TFCC is limited to a meniscoid articular disc or a congenital perforation. To our knowledge, an atraumatic bucket handle abnormality has not been described yet. Clinical Relevance This congenital abnormality of the TFCC could be mistaken for a traumatic lesion on MRI, or during wrist arthroscopy; therefore, it is important to realize that this entity may occur and does not require treatment.

Triangular Fibrocartilage

Triangular fibrocartilage complex (TFCC) injuries were suspected clinically in 22 wrists of 21 patients, but arthrography and MRI assessments of this structure were normal. As conservative therapy for 2 months did not improve their symptoms, wrist arthroscopy was then performed. Although no abnormalities of the TFCC and ligaments were observed, meniscus homologue-like tissue which arose from TFCC was riding on the articular surface of the triquetrum. After resection of this soft tissue with a shaver and a punch, the symptoms disappeared in all cases. The arthroscopic findings suggested that a portion of TFCC that was originally attached to the ulnar side of the triquetrum had become detached.

Background: Triangular fibrocartilage complex (TFCC) injuries are a known cause of ulnar-sided wrist pain. Wrist arthroscopy is the gold standard for diagnosis of these lesions and is becoming a more frequent method of treatment. Isolated radial-sided tears are uncommon and treatment of these lesions is controversial. There are few reports on repair techniques. Here we report on a novel arthroscopic, all-inside technique for traumatic radial-sided TFCC tears that resulted in full range of motion, significant improvement in pain, and ultimately return to sport. Methods: This is a single case report describing an all-inside, arthroscopic repair of a radial-sided TFCC tear. The techniques and postoperative protocol are discussed. Clinical outcomes were reported at final follow-up of 3.5 months. Results: At final follow-up, our patient had full wrist range of motion, 95% strength, occasional 1/10 pain, and returned to sport at her previous level of play. There were no complications. Conclusion: Although just a single case report, our patient had an excellent result based on modified Mayo wrist score. When comparing our result and the previous literature, this technique seems to be a valid method for addressing radial-sided TFCC tears.
