Clinical Investigation on Safety, Performance and Effectiveness of Sono-instruments
Trigger FingerTrigger Thumb1 moreCarpal Tunnel (CT) syndrome is a collection of characteristic symptoms and signs that occurs following compression of the median nerve within the CT. In Trigger Finger / trigger thumb (TF), one of the most common causes of hand pain and disability, the flexor tendon causes painful popping or snapping as the patient flexes and extends the digit. In case of failure of non-operative treatments, patients with CT syndrome or TF are operated. Clearly any improvement in surgical device design would be of great advantage to the patient and the surgeon. Spirecut's single use, pre-CE Sono-Instruments (SI) allow the percutaneous treatment of Carpal Tunnel (CT)syndrome and Trigger Finger/thumb (TF) under sonography (instead of open or endoscopic approach). Two models will be assessed in this clinical investigation: The Carpal Tunnel Sono-Instrument® (CT-SI), for CT syndrome release, by progressively cutting the transverse carpal ligament. The Trigger Finger Sono-Instrument® (TF-SI), for TF release by progressively cutting the A1 annual pulley. Using those SI, surgical procedures can be performed without endangering adjacent structures (e.g. median nerve and branches, ulnar pedicle, superficial carpal arch, digital pedicles, flexor tendons).
A Comparison Between Sonoguided Injection Corticosteroid and Hyaluronic Acid Injection in Treatment...
Trigger FingerThe study is to compare the effect between steroid injection and Hyaluronic acid in treatment trigger finger. Using sonoguided injection technique achieves more accurate injection location and therapeutic effect. We hypothesize hyaluronic acid has both lubricant and anti-inflammation effect in treatment of trigger finger, and can provide better outcome and lower adverse effect than steroid injection.
Bupivacaine Versus Lidocaine Local Anesthesia
Carpal Tunnel SyndromeTrigger FingerThe use of local anesthetics has become an important aspect of pain management in surgical settings and is currently recommended in pain management guidelines. Elective outpatient hand surgeries, such as carpal tunnel or trigger finger release, cause minimum tissue disruption and are short in duration. As a result, these local anesthetic agents are a major component in post-operative pain control. The most commonly used local anesthetic agents are Lidocaine and Bupivacaine. Lidocaine acts faster (within 2-5 minutes of injection) and for this reason is often favored in outpatient setting for pre-incisional injection. However its effects only last up to 2 hours, without epinephrine, and 3 hours, with epinephrine. On the other hand, Bupivacaine, has a slower onset of action (about 5-10 minutes after injection) but its effects last much longer, for about 4-8 hours. The delay in onset of action makes it a less popular option as a primary source of local anesthesia in outpatient hand surgery. Given the longer duration of anesthesia offered by Bupivacaine, the investigators believe that by giving it pre-operatively in elective outpatient hand surgeries will offer more effective post operative pain control compared to using Lidocaine only. There is limited published data confirming the effectiveness of use of pre-operative Bupivicaine in improved postoperative pain control and decreased consumption of narcotics. Therefore, the aim in this study is to compare the postoperative pain experienced by patients undergoing either elective carpal tunnel release or trigger finger release as well as their use of pain medications when the incision site is infiltrated preemptively with Lidocaine versus Bupivacaine. The investigators believe that adequate post surgical pain control is essential for patients' full functional recovery. Poorly controlled post surgical pain increases incidence of surgery related complications and thus increased health care costs. It can also reduce patients' mobility, delay their return to full function,. If poorly controlled, post surgical pain may progress to chronic pain and rarely complex regional pain syndromes may ensue.
Differences in Flare Reaction Incidence and Intensity Following Trigger Finger Injections
Trigger FingerTwo common corticosteroids used for trigger finger treatment are betamethasone and methylprednisolone. Both injections are effective in treating trigger finger and the decision of which to use in treatment is currently a matter of the current practice and physician preference. The goal through this randomized trial is to see whether there is a difference between these two corticosteroids in inducing flare reactions and if there are any differences in the peak level of pain and their duration. Findings indicating a statistically significant difference in the incidence and/or intensity of the flare reactions would be clinically significant and would be evidence supporting the switch of current practice to one corticosteroid over the other.
Endoscopic Trigger Finger Release
Trigger FingerThe purpose of this study is to compare recovery, scar, and patient satisfaction after retrograde endoscopic trigger finger release versus the standard open surgical treatment.

Group A 40 patients: Underwent ultrasound guided methyl prednisolone acetate injection, between A1 pulley and tendons .Group B 35 patients :Underwent ultrasonography-guided percutaneous A1 pulley needle release .All patients were subjected to the following before and after intervention by 1 and 3 months , DASH, trigger finger classification grade & VAS
Trigger Finger Corticosteroid Injection With and Without Local Anesthetic
Trigger FingerSteroid injection is the first line treatment for trigger finger. Steroid injection is sometimes mixed with a local anesthetic.
Comparison of Trigger Finger Orthotic Wearing Schedules
Trigger FingerA randomized prospective pre-post test case series was chosen for this study. This case series will provide feasibility data in preparation for a randomized controlled study of this topic in the future. The primary research question for this case series is as follows: Do the three proposed orthotic wearing schedules provide varying results in the reduction of digital triggering severity and level of pain experienced by those with trigger finger? The following three orthotic wearing schedules will be investigated: only during waking hours, only while sleeping, and continuously. To examine the feasibility of the study the following questions are posed: What was the length of time required to recruit nine eligible participants for the case series through the outpatient clinic utilized for this feasibility study? Based upon the rate of recruitment for the feasibility study, were the initial methods of recruitment adequate or did additional strategies need to be implemented to recruit a sufficient number of participants within the desired time frame? Were the orthotics utilized for the study comfortable to wear and functional for the participants while performing their activities of daily living? Were the number and type of adverse events including redness, edema, tingling, or numbness associated with orthotic wear similar across the groups, limited, non-serious, and did not interfere with orthotic wearing? Did participants wear their orthotics for the prescribed wearing schedule?
Percutaneous Release vs Steroid Injection for Trigger Finger
Trigger FingerTrigger fingers (TF) is the common cause of pain and disturbed function of hand. Many studies show that percutaneous release of A1 pulley has better outcome than the steroid injection. However, over the past many years, steroid injection has been considered as the choice of treatment after the failure of conservative treatment methods. The aim of this study is to assess the effect of percutaneous release of A1 pulley compared with the local Steroid injection in the treatment of trigger fingers. This study is based on a randomized clinical trial to compare the effect of the percutaneous release of A1 pulley with steroid injection in trigger fingers. A total of 112 participants aged 18 years and above suffering from trigger fingers with failed conservative treatment will be intervened randomly (56 participants in injection group and 56 participants in percutaneous release group). The Quinnell's classification, VAS scoring system and active range of movement in the affected site will be assessed at the baseline and the same criteria will be at one month and three month as end line assessment. Statistical analyses will be performed using independent t-test and Mann Whitney U test to compare between the two means. The outcome of this study will help to guide the physicians to choose the better therapeutic approach among the patients suffering from trigger fingers.
Study of Open and Percutaneous Release of Acquired Trigger Thumb
Trigger ThumbTrigger finger, also known as trigger digit or stenosing tenovaginitis, is caused by a size mismatch between the flexor tendon and the A1 pulley, which is generally characterized by pain, swelling, the limitation of finger range of motion and a symptomatic locking or clicking sensation. Conservative treatment options include the application of non-steroidal anti-inflammatory drugs (NSAID), physiotherapy, electrotherapy, splinting and corticosteroid injection but not always effective with regard to frequent recurrence. Open surgical release of the A1 pulley remains the gold standard of treating symptomatic trigger finger. While percutaneous release is a minimal invasive alternative and gaining popularity for the index, middle ring and little fingers, investigations for the surgical efficacy on thumb is few and far between. Investigators believe that a carefully conducted operation with proper positioning of the thumb, wide-awake approach and meticulous technique can achieve similar efficacy and safety in terms of possibly less intraoperative pain, imperceptible scar and early return to daily activities and routine work. The hypothesis of this study is that by using a proper positioning of thumb, wide awake approach and meticulous technique in conducting percutaneous release of trigger thumb can achieve similar efficacy and safety compared to that of open release surgical method. Moreover, percutaneous release of trigger thumb can generate less intraoperative pain, imperceptible scar and promote early return to routine work. Hence, the objective of this study is to investigate and compare the safety, effectiveness and outcome of percutaneous release versus traditional open release for trigger thumbs.
