Tenosynovitis refers to an inflammatory condition involving the synovial sheath of a tendon. Stenosing tenosynovitis is a peculiar entity caused by multiple factors, including local anatomy, mechanical factors, and hormonal factors. The main forms include de Quervain tendinopathy; trigger finger (stenosing tenosynovitis involving the flexor digitorum tendons); stenosing tenosynovitis of the extensor carpi ulnaris, extensor carpi radialis, or extensor comunis tendons; stenosing tenosynovitis of the flexor hallucis tendon; and stenosing tenosynovitis of the peroneal tendons. The cardinal finding on ultrasonography is the presence of a thickened retinaculum or pulley that constricts the osseofibrous tunnel through which the tendon runs.Sommario Le tenosinoviti sono infiammazioni delle guaine sinoviali dei tendini. Le tenosinoviti stenosanti sono delle entità particolari, condizionate da molteplici fattori. Si tratta di patologie favorite dall'anatomia locale, da fattori meccanici ed ormonali. Le principali tenosinoviti stenosanti sono: la tendinopatia di de Quervain, la tenosinovite stenosante dei tendini flessori delle dita o dito a scatto, la tenosinovite stenosante del tendine estensore ulnare del carpo, dei tendini estensori radiali del carpo e degli estensori comuni, la tenosinovite stenosante del tendine flessore dell'alluce, la tenosinovite stenosante dei tendini peronei. La loro diagnosi si basa sull'ecografia, che mostra un segno cardine: l'ispessimento del retinacolo o della puleggia rispetto al tendine ed il suo carattere stenosante. ª

In this study mid-and long-term outcomes of the cases with trigger finger we treated using Admix NoKorTM have been presented. Percutaneous release procedures were applied for 24 fingers of 22 (19 female, 3 male patients; mean age, 57; range, 39-72) patients between May 2009 and May 2011. Preoperatively US was performed so as to confirm the presence of trigger finger. Diameters of the tendons of the affected and intact hands measured using US, were compared so as to be able to demonstrate thickening of the tendon of the trigger finger. The patients were monitored for an average period of 25.2 (range, 14-36) months. During surgery, clinically loss of the catching sensation was observed. In two patients percutaneous trigger finger release failed, so we have to proceed with open surgery. During open surgery, we observed longitudinal wounds on the tendon. One patient developed unilateral radial digital nerve damage. Percutaneous release of the trigger finger using Admix NoKorTM 16-G gauge needle can be preferred in the treatment of trigger finger. Trigger finger of the first digit requires more attentive approach and one should be aware of the complications. If required open surgery can be preferred.

Our personal treatment concept for trigger thumb in children is presented. The guiding symptoms are fixed flexion deformity, (painful) restriction of motion (with a click phenomenon) or persistent extension deformity. Although it is a simple pathology, careful diagnosis is mandatory to rule out other reasons with the same symptoms as trigger thumb, as some of these will lead to severe aesthetic and functional impairment. In 26 patients with persistent symptoms, the A1 ring ligament of the thumb was cut. Free active and passive joint motion was comparable to the opposite side in 92.7% of patients. In 2 cases a secondary operation was necessary because of incomplete A1 ring ligament release. If it is diagnosed and operated on early with a careful operative technique, nowadays no aesthetic or functional impairment should occur in children because of trigger thumb.
