Wnt/β-catenin signaling is activated when extracellular Wnt ligands bind Frizzled (FZD) receptors at the cell membrane. Wnts bind FZD cysteine-rich domains (CRDs) with high affinity through a palmitoylated N-terminal "thumb" and a disulfide-stabilized C-terminal "index finger," yet how these binding events trigger receptor activation and intracellular signaling remains unclear. Here we report the crystal structure of the Frizzled-4 (FZD4) CRD in complex with palmitoleic acid, which reveals a CRD tetramer consisting of two cross-braced CRD dimers...

Trigger finger is a mechanical problem with many etiological factors as possible causes, such as diabetes mellitus, carpal tunnel syndrome and repetitive finger movements. Although it can afflict anyone, it is much commoner in middle-aged women than men and the most commonly involved digit is reported to be the thumb. The diagnosis is mainly based on clinical symptoms during examination and first-line treatment is conservative with splinting and corticosteroid injections. Surgical open release is the "gold standard" of trigger finger treatment because it allows more careful inspection of the surgical area and is highly effective with low complication rates...

BACKGROUND: Pathologic crying, devoid of any emotional counterpart, is known to occur as a consequence of various brain stem, cortical hemispheric and cerebellar lesions or, quite exceptionally, of "dacrystic" epilepsy. The case reported here suggests that thalamic lesions may also cause crying spells, under the special circumstances described below. CASE PRESENTATION: After a mild left thalamic stroke a caucasian 77 years old man presented with crying spells with no emotional counterpart, triggered by thumb-index rubbing of his right hand...

The hand function of patients who suffer from trigger finger can be impaired by the use of traditional splints. There is also a risk of systemic side effects with oral non-steroidal anti-inflammatory drugs (NSAIDs) used for pain relief. Microneedle-assisted transdermal drug delivery offers an attractive alternative for local delivery of NSAIDs. However, traditional microneedle arrays fabricated on flat surfaces are unable to deliver drugs effectively across the undulating skin surface of affected finger(s)...

Congenital thumb anomalies are common and have a major impact given the specific functional role of the thumb. They may occur alone or as part of a multiple congenital anomaly syndrome. The primary goal of surgical management is to improve or restore pincer grip. In patients with 'congenital' trigger thumb, the A1 pulley must be released if the interphalangeal joint remains in fixed flexion. Thumb duplication is generally managed by reconstruction of the thumb from the predominant (ulnar-based) digit; the accessory (radial-based) digit is excised after collection of its tissue components needed for the reconstruction programme...

PURPOSE: Trigger finger is the most common entrapment tendinopathy, with a lifetime risk of 2% to 3%. Open surgical release of the flexor tendon sheath is a commonly performed procedure associated with a high rate of success. Despite reported success rates of over 94%, percutaneous trigger finger release (PFTR) remains a controversial procedure because of the risk of iatrogenic digital neurovascular injury. This study aimed to evaluate the safety and efficacy of traditional percutaneous and ultrasound (US)-guided first annular (A1) pulley releases performed on a perfused cadaveric model...

REVIEW
Juan M Giugale, John R Fowler
Trigger fingers are common tendinopathies representing a stenosing flexor tenosynovitis of the fingers. Adult trigger finger can be treated nonsurgically using activity modification, splinting, and/or corticosteroid injections. Surgical treatment options include percutaneous A1 pulley release and open A1 pulley release. Excision of a slip of the flexor digitorum superficialis is reserved for patients with persistent triggering despite A1 release or patients with persistent flexion contracture. Pediatric trigger thumb is treated with open A1 pulley release...

Leiomyoma is a generally benign tumour and common in the uterine smooth muscle. In some cases, it is found in other parts of the human body. In our study, we report the case of a 61-year-old woman with a painless cystic lesion on the first left thumb associated with trigger finger. The first diagnostic hypotheses were ganglionic cyst and giant cell tumour, however, after surgical excision and histological analysis, it was revealed to be a rare leiomyoma of the hand. We report a clinical case and detailed histopathological study, with 12 high-resolution images stained with: H&E, Smooth Muscle Actin, Desmin, S-100 and CD34...

REVIEW
Eric Y Chang, Karen C Chen, Christine B Chung
Trigger finger (or trigger thumb), also known as sclerosing tenosynovitis, is a common clinical diagnosis that rarely presents for imaging. Because of this selection bias, many radiologists may not be familiar with the process. Furthermore, patients who do present for imaging frequently have misleading examination indications. To our knowledge, magnetic resonance (MR) imaging findings of trigger thumb have not been previously reported in the literature. In this article, we review the entity of trigger thumb, the anatomy involved, and associated imaging findings, which include flexor pollicis longus tendinosis with a distinct nodule, A1 pulley thickening, and tenosynovitis...
