OBJECTIVE: To study the clinical effectiveness of the topical application of tranexamic acid in hand tendon release.
METHODS: This was a randomized controlled trial conducted after receiving approval from the local ethics committee according to guidelines from the Helsinki Declaration. Eighty patients who underwent hand tendon release operation in our hospital from January 2021 to December 2022 were included and randomly divided into 2 groups. Patients in the tranexamic acid group (40 cases) received intraoperative topical application of 2 g of tranexamic acid after tendon release, while patients in the conventional group (40 cases) did not receive topical application of tranexamic acid during operation. The operation time, perioperative hemoglobin changes, total blood loss, incidence of early postoperative complications, and total active movement (TAM) before surgery and 6 months after surgery were compared between the 2 groups. The continuous variable which follows normal distribution expressed by mean ± SD and used t-test to compare between groups. Meanwhile, categorical variables were used by Chi-square test, and a p < 0.05 indicated that the differences were statistically significant.
RESULTS: Both groups were followed up for 7 - 18 months, with a mean of 10.3 months. Postoperative decrease in hemoglobin was significantly less in the tranexamic acid group than in the conventional group (t = 7.611, p < 0.001). The total blood loss in the tranexamic acid group (74.33 ± 20.50) mL was less than that in the conventional group (83.05 ± 17.73) mL, and the difference was statistically significant (p < 0.05). Both groups showed improvement in thumb/finger flexion and extension range of motion after surgery, and the TAM improved compared with those before surgery, and the difference was statistically significant (p < 0.001). The TAM improved more significantly in the tranexamic acid group (87.68° ± 10.44°) than in the conventional group (80.47° ± 10.93°) at 6 months after surgery, with a statistically significant difference (t = 3.013, p < 0.001). There was no significant difference in operation time and incidence of early postoperative complications between the 2 groups (p = 0.798, 0.499, respectively).
CONCLUSIONS: The topical application of tranexamic acid during hand tendon release can significantly reduce postoperative bleeding and improve surgical efficacy, which is worth promoting.

BACKGROUND: Trigger finger (also known as stenosing tenosynovitis) is a chronic inflammatory disorder that affects the fingers and causes discomfort and functional impairment. It is estimated to affect 2-3.6% of the population and is more common in manual laborers and individuals engaged in repetitive hand activities. This study comprehensively compares the efficacy of ultrasound-guided release versus traditional open surgery in treating trigger fingers.
METHODS: We systematically searched PubMed, Scopus, EMBASE, and the Cochrane Library to identify relevant studies. Inclusion criteria were studies evaluating ultrasound-guided release of trigger finger (grade 2 and higher) compared with open surgical release. A meta-analysis was performed by Revman software 5.4.1 to assess efficacy, utilizing appropriate statistical methods to address heterogeneity. Primary outcome measures included \"Quick Disability of Arm, Shoulder, and Hand\" (QDASH) scores, Grip strength, and the Visual Analogue Scale (VAS). Secondary outcome measures included Days of stopping analgesia, full-digit flexion and extension, days to return to normal activities, pinch strength, Quinnell grading score, and bow strengthening.
RESULTS: Out of the initial pool of 820 studies, five met the inclusion criteria, including 275 patients with 283 trigger digits. The analysis revealed significant differences favoring the ultrasound-guided release group over the surgical group for improvement in Quick Disability of Arm, Shoulder, and Hand score in the first month (MD -0.48, 95% CI: 0.75 to -0.2, P = .0007, I2  = 20%). The difference was not statistically significant in the 3-month follow-up period (MD -2.25, 95% CI: -0.54 to 0.05, P = .1, I2  = 0%). Additionally, there is a significant difference in the days required for return to normal activities in favor of the ultrasound release approach (MD -13.78, 95% CI: -16.68 to 10.89, P = .00001, I2  = 68%). The data displayed heterogeneity, which was resolved through sensitivity analysis that also favored the ultrasound-guided group. In terms of grip strength, full-digit flexion and extension, VAS, and days of stopping analgesia no significant differences were observed.
CONCLUSIONS: Ultrasound-guided release showed advantages over open surgical release, resulting in improved QDASH score and quicker return to normal activities. This offers a minimally invasive, successful alternative to open surgery, reducing associated risks. Further studies with long-term follow-up are recommended.

The purpose of this study was to report on a series of dancers who had undergone flexor hallucis longus (FHL) tenolysis/tenosynovectomy after having failed conservative management. Institutional human subjects committee approval was obtained prior to initiating this study. This study is a retrospective case series of 58 dancers and 63 ankles who underwent FHL tenolysis/tenosynovectomy via an open posteromedial approach by a single surgeon between 1993 and 2017. All patients were interviewed and charts reviewed. Collected variables included: preoperative and postoperative pain levels, time to return to dance, and subjective satisfaction with the procedure. Age, primary dance form, and level of dance were determined. Mean preoperative pain level decreased significantly postoperatively. Mean time to return to dance was 7.1 weeks. There was a 98% (62/63) return to dance at some level while 97% (61/63) of patients returned to dance symptom-free. There were no neurovascular or other major complications. Minor complications included stiffness at follow-up (6.3%, 4/63), superficial wound infection (3.1%, 2/63), and hypertrophic scar (4.8%, 3/63). Over 97% (61/63) of dancers considered the procedure a success and 98% (62/63) of dancers would repeat the procedure. This is one of the largest series reported of isolated FHL tenolysis/tenosynovectomy in dancers who have failed nonoperative management. Satisfactory pain relief and return to dance with a low complication rate may be expected from this surgical procedure. The results of this study can be used to help dancers and their providers make informed decisions about treatment in isolated FHL tendinitis.

BACKGROUND: A true accessory extensor tendon of the thumb seems to be rare. We found a variation of the accessory extensor pollicis longus (EPL) tendon while performing an emergency surgical procedure. Identification of this accessory tendon during emergency surgery has not been previously reported.Case presentation: A 43-year-old man presented to our hospital after sustaining a work-related injury involving a saw. During the operation, the tendons of the EPL, accessory EPL, and extensor pollicis brevis were severed. The lacerated tendon and tendon sheath were repaired, and the wrist and thumb were positioned in extension. The patient\'s postoperative activity returned to normal without the need for a second tendon release operation.
CONCLUSIONS: Surgeons should be aware of this anatomic anomaly of the EPL tendon. Presentation of our case increases clinicians\' chances of preoperatively detecting this anomaly, which can improve surgical outcomes.

OBJECTIVE: Snapping of the iliotibial band over the greater trochanter should be eliminated by reducing tension via lengthening, release, and incision of the iliotibial band.
METHODS: Positive clinical examination and painful snapping of the iliotibial band over the greater trochanter, despite extensive conservative treatments, for over 6 months.
METHODS: Weakness of the abductor muscles with positive Trendelenburg sign.
METHODS: Direct approach to the iliotibial tract. The snapping of the tract over the greater trochanter can be provoked and observed in situ via internal rotation and adduction of the hip. Lengthening of the iliotibial band is performed with a tongue-shape flap technique (\"Griffelschachtelplastik\") directly over the greater trochanter. This leads to simultaneous release and incision over the greater trochanter. Hereafter, no snapping of the tract should be observed upon motion analysis.
METHODS: Pain-adapted mobilization with full weightbearing, no active abduction against resistance, and no adduction over and exceeding the 0‑degree level for 6 weeks.
RESULTS: The snapping of the iliotibial band could be eliminated in all cases. Apart from 2 patients with previous surgery who still complain of unimproved pain, improvement of symptoms with consequent subjective satisfaction with the outcome of surgery was reported in all cases.

BACKGROUND: Internal snapping hip is a common clinical condition, characterized by an audible or palpable snap of the medial compartment of the hip. In most cases it is asymptomatic, while in a few patients, mostly in athletes who participate in activities requiring extremes of hip range of motion, the snap may become painful (internal snapping hip syndrome - ISHS).
METHODS: This is a review of current literature, focused on the pathogenesis, diagnosis and treatment of ISHS.
CONCLUSIONS: The pathogenesis of ISHS is multifactorial, and it is traditionally believed to be caused by the tendon snapping over the anterior femoral head or the iliopectineal ridge. Most cases of ISHS resolve with conservative treatment, which includes avoidance of aggravating activities, stretching, and NSAIDs. In recalcitrant cases, surgery may be indicated. Better results have been reported with endoscopic iliopsoas tendon release compared with open techniques, which may be related to the treatment of concomitant intra-articular pathologies. Furthermore, endoscopic treatment showed fewer complications, decreased failure rate and postop erative pain. It is important to remember that in most cases, a multiple iliopsoas tendon may exist, and that the incomplete release of the iliopsoas tendon can be a reason for refractory pain and poor results. Then, even if of not clinical relevance at long term follow-up, patients should be told about the inevitable loss of flexion strength after iliopsoas tenotomy.
METHODS: II.

OBJECTIVE: To describe an ultrasound-guided proximal percutaneous tenotomy technique of long head of the biceps tendon (LHBT).
METHODS: Three fresh cadavers with no prior shoulder surgery or LHBT tears were included in the study. A single experienced musculoskeletal radiologist completed six ultrasound-guided proximal percutaneous tenotomies of LHBT. A superficial to deep approach was performed on four shoulders using an arthroscopic banana blade or retractable blade. A deep to superficial approach was performed on two shoulders using an arthroscopic hook blade. A blinded anatomist dissected each specimen and graded the tenotomy, length of proximal LHBT stump, and evidence of iatrogenic injuries.
RESULTS: Four of the six cadaveric LHBTs were fully transected. The two partially transected tenotomies were performed using the arthroscopic banana and retractable serrated blades (63% and 80% transections, respectively). The proximal LHBT stump mean length was 2.6 cm (95% CI, 1.8-3.4). There was no evidence of iatrogenic lesions.
CONCLUSIONS: This cadaveric study showed that the ultrasound-guided percutaneous tenotomy of the LHBT is a feasible procedure. The deep to superficial approach using an arthroscopic hook blade resulted in complete transection. Further cadaveric studies with larger numbers are warranted to confirm this novel technique\'s applicability in clinical practice.
