“…The carpal tunnel was released in all cases of the present series that were associated with CTS. The disappearance of triggering has been demonstrated in all the reports after surgical treatment [2,6,10]. Similarly, the symptoms were resolved in all patients of the present series following the surgical intervention.…”

“…In these cases, the evaluation of crepitus of intracarpal tunnel might help find an intracarpal mass. If crepitus is noticed through a slight pressure over the transverse carpal ligament, further evaluation such as MRI is warranted to differentiate the nature of tunnel-occupying lesion causing the trigger wrist [6]. In some cases of trigger wrist, the characteristic snapping or triggering around wrist might be absent.…”

“…In some cases of trigger wrist, the characteristic snapping or triggering around wrist might be absent. The clinical differentiation of trigger wrist is difficult in these cases [6]. Ultrasound imaging can provide a dynamic picture for the tendon triggering and could be helpful if trigger finger at the wrist is suspected [7].…”

“…Since these etiologies might also narrow the carpal tunnel, the median nerve might be compressed, as well. For this reason, patients with trigger wrist are frequently presented with CTS [6].…”

Background: Trigger wrist is a relatively rare hand disorder that refers to the painful snapping and clicking or triggering at the wrist level during finger or wrist movements. Objectives: In this study, we aimed at reporting a series of trigger wrist and discussing their etiology, as well as their clinical manifestation and outcomes. Methods: In this retrospective study, the patients with the definitive diagnosis of trigger wrist were reviewed. Their demographics and clinical symptoms were extracted from their medical records. The symptoms of median neuropathy, including weakness or atrophy of the thenar muscles, persistent numbness, and paresthesia were recorded to investigate the association with Carpal Tunnel Syndrome (CTS). Results: A total of seven patients with the Mean±SD age of 35.5±10.3 years were included in the study. A benign mass was the etiology of trigger wrist in all cases, with giant cell tumor of flexor tendon sheet as the most common etiology (57.1%). Trigger wrist was associated with CTS in three cases (42.8%), in all of whom the tumor size was larger than the average. Pain and snapping with or without palpable mass were the main clinical symptoms of the patients that completely disappeared by surgical removal of the lesion. A mean 40.3 months follow-up of the patients was uneventful. Conclusion: Benign neoplasms could be considered as the most common etiology of trigger wrist. Since many patients with trigger wrist might have CTS, too, the careful differentiation of these entities is necessary. Once accurately diagnosed, surgical intervention is entirely curative.

“…In addition to carpal tunnel syndrome, another disorder in which aberrant muscle belly may be a contributing mechanism is trigger wrist. [23][24][25] In rare cases, trigger wrist secondary to aberrant muscle may even present with carpal tunnel syndrome. 24,26 Clinical presentations of trigger wrist include painful clicking, snapping, or catching sensation around the carpal tunnel during finger or wrist motion; in severe cases, wrist and finger motion may be limited by a triggering or locking of the joints.…”

Musculoskeletal sonography is being widely used for evaluation of structures within the carpal tunnel. While some anatomical variants, such as bifurcated median nerves and persistent median arteries, have been well documented, limited literature describes the sonographic appearance of aberrant muscle bellies within the carpal tunnel. Multiple examples of the sonographic appearance of flexor digitorum superficialis and lumbrical muscle bellies extending into the carpal tunnel are provided. Techniques for static image acquisition and analysis are discussed, and the use of dynamic imaging to confirm which specific muscle belly is involved is described. Knowledge of the potential presence of muscle bellies in these images and ability to identify these structures is vital to avoid misclassification or misdiagnosis as abnormal pathology. The case examples are situated among current published evidence regarding how such anomalies may be related to the development of pathologies, such as carpal tunnel syndrome.
