Surgical Repair of Acute TFCC Injury

The patient with an acute painful wrist

Patients with wrist pain commonly present to primary care and emergency departments. A detailed history and examination, alongside relevant imaging, will help find the correct diagnosis and ensure that patients receive the correct treatment in a timely manner. This article summarises the key points in history and examination and the role of imaging, including suggestions of which modality should be requested. Finally, important acute pathologies are highlighted, including fractures, soft tissue injuries and infection, with examples of their relevant imaging.

Advances in the Repair of Palmer type IB TFCC Injuries With Wrist Arthroscopy

The triangular fibrocartilage complex (TFCC) is essential for maintaining wrist stability. Injury-caused pain is the primary cause of ulnar wrist pain. The TFCC injury refractory to conservative treatment requires further surgical treatment, and because Palmer type IB tears belong to peripheral injuries due to their proximity to the blood supply area, arthroscopic suture repair has become the preferred surgical method for TFCC injury repair, exhibiting strong healing ability. This study reviewed the anatomy of TFCC, injury classification, and advances in arthroscopic suturing for treating Palmer type IB.

Return to Activity After Arthroscopically Assisted Triangular Fibrocartilage Complex Repair: A Systematic Review

OBJECTIVE

To evaluate patients' ability to return to preinjury activity level after arthroscopically assisted triangular fibrocartilage complex (TFCC) repair.

DATA SOURCES

The PubMed electronic library was systematically searched from inception to August 2021 for any eligible articles using a combination of the phrases "TFCC," "return to sport," "return to work," and "athlete."

RESULTS

Studies that evaluated patients who had undergone arthroscopic repair of isolated TFCC injury and reported objective or patient-reported outcome measures were included. Fifteen studies representing 478 patients fulfilled the inclusion criteria. An average of 84% of patients were able to fully return to their previous work or sport activities. Most studies reported that range of motion (ROM) and grip strength (GS) both returned to >90% of the contralateral side, and every study that evaluated pain levels found a significant reduction in pain postoperatively. Mayo Modified Wrist Score was reported as excellent or good in 83% of patients, and the average Disabilities of the Arm, Shoulder, and Hand score was 13.8 postoperatively.

CONCLUSION

Patients were able to return to their previous work or sport activities at a high rate after TFCC repair, even those participating in more strenuous activities. Measurable functional outcomes of ROM and GS were also reliably restored to near preinjury levels. Patient-reported outcomes of pain and disability were similarly improved after TFCC repair. Current literature has established the long-term success of TFCC repair but is lacking in evaluation of the time points at which patients can expect functional status to be restored.

Failed Triangular Fibrocartilage Complex Repair and Reconstruction

Unsuccessful triangular fibrocartilage complex (TFCC) repair or reconstruction is poorly defined, often stemming from multiple causes, both patient and surgeon-related. Complete evaluation of the patient's psychosocial status and involvement in any litigation claims is essential, as is a thorough history, physical examination, and imaging workup to accurately diagnose TFCC injury, along with any concomitant wrist pathology. Awareness of common complications and technical errors is critical, and preventive treatment strategies should be implemented to minimize these events.
