We describe an arthroscopic rein-type capsular suture that approximates the triangular fibrocartilage complex to the anatomical footprint, and report the results at a minimum 12 month follow-up. The procedure involves two 3-0 polydioxanone horizontal mattress sutures inserted 1.5 cm proximal to the 6-R and 6-U portals to obtain purchase on the dorsal and anterior radioulnar ligaments, respectively. The two sutures work as a rein to approximate the triangular fibrocartilage complex to the fovea. Ninety patients with Type IB triangular fibrocartilage complex injuries were included retrospectively. The 12-month postoperative Modified Mayo Wrist scores, Disabilities of Arm, Shoulder and Hand scores and visual analogue scale for pain showed significant improvements on preoperative values. Postoperative range of wrist motion, grip strength and ultrasound assessment of the distal radioulnar joint stability were comparable with the normal wrist. The patients had high satisfaction scores for surgery. There were minor complications of knot irritation. No revision surgery for distal radioulnar joint instability was required. It is an effective and technically simple procedure that provides a foveal footprint contact for the triangular fibrocartilage complex. Level of evidence: IV

Introduction Triangular fibrocartilage complex (TFCC) injuries are associated with distal radioulnar joint (DRUJ) instability and impaired wrist proprioception. Sensorimotor training of extensor carpi ulnaris (ECU) and pronator quadratus (PQ) can enhance DRUJ stability. With limited evidence on effectiveness of TFCC sensorimotor rehabilitation, this study aimed to evaluate the effects and feasibility of a novel wrist sensorimotor rehabilitation program (WSRP) for TFCC injuries. Methods Patients diagnosed with TFCC injuries were recruited from May 2018 to January 2020 at an outpatient hand clinic in Singapore General Hospital. There are four stages in WSRP: (1) pain control, (2) muscle re-education and joint awareness, (3) neuromuscular rehabilitation, and (4) movement normalization and function. WSRP also incorporated dart throwing motion and proprioceptive neuromuscular facilitation. Outcome measures included grip strength measured with grip dynamometer, numerical pain rating scale, joint position sense (JPS) measurement, weight bearing measured with the ‘push-off’ test, and wrist function reported on the Patient Rated Wrist Hand Evaluation. Results Ten patients completed the WSRP. Mean changes were compared with minimal clinically important differences (MCID) for outcomes. All patients achieved MCID on pain, 70% of patients achieved MCID on grip strength, weight bearing and wrist function. Paired t-tests and Cohen’s D for outcome measures were calculated. There were large effect sizes of 2.47, 1.35, and 2.81 for function, grip strength and pain respectively, and moderate effect sizes of 0.72 and 0.39 for axial loading and JPS respectively. Discussion WSRP presents a potential treatment approach in TFCC rehabilitation. There is a need for future prospective clinical trials with control groups.

Abstract Objective The objective of the study is to provide a reference for morphology, homogeneity, and signal intensity of triangular fibrocartilage complex (TFCC) and TFCC-related MRI features in adolescents. Materials and methods Prospectively collected data on asymptomatic participants aged 12–18 years, between June 2015 and November 2017, were retrospectively analyzed. A radiograph was performed in all participants to determine skeletal age and ulnar variance. A 3-T MRI followed to assess TFCC components and TFCC-related features. A standardized scoring form, based on MRI definitions used in literature on adults, was used for individual assessment of all participants by four observers. Results per item were expressed as frequencies (percentages) of observations by all observers for all participants combined (n = 92). Inter-observer agreement was determined by the unweighted Fleiss’ kappa with 95% confidence intervals (95% CI). Results The cohort consisted of 23 asymptomatic adolescents (12 girls and 11 boys). Median age was 13.5 years (range 12.0–17.0). Median ulnar variance was −0.7 mm (range − 2.7–1.4). Median triangular fibrocartilage (TFC) thickness was 1.4 mm (range 0.1–2.9). Diffuse increased TFC signal intensity not reaching the articular surface was observed in 30 (33%) observations and a vertical linear increased signal intensity with TFC discontinuation in 19 (20%) observations. Discontinuation between the volar radioulnar ligament and the TFC in the sagittal plane was seen in 23 (25%) observations. The extensor carpi ulnaris was completely dislocated in 10 (11%) observations, more frequent in supinated wrists (p = 0.031). Inter-observer agreement ranged from poor to fair for scoring items on the individual TFCC components. Conclusion MRI findings, whether normal variation or asymptomatic abnormality, can be observed in TFCC and TFCC-related features of asymptomatic adolescents. The rather low inter-observer agreement underscores the challenges in interpreting these small structures on MRI. This should be taken into consideration when interpreting clinical MRIs and deciding upon arthroscopy.

Triangular Fibrocartilage

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.
