Objectives: This study aims to describe a retrospective study using prospectively gathered data to compare mini-open and extended open release techniques for moderate to severe carpal tunnel syndrome (CTS).

Patients And Methods: The data of 198 consecutive patients (139 males, 59 females; mean age 57.0±4.5 years; range, 44 to 75 years) treated for CPS were used. For matching, age, gender and severity of the compression, the Greathouse Ernst Halle Schaffer neurophysiological classification system was used. After matching, 63 observations in each group (group 1: mini-open and group 2: extended open) were used for analysis. A Jamar hydraulic hand dynamometer was used to measure pre- and postoperative third month grip strengths. The key pinch test was performed also at third month. Patients completed the Boston Carpal Tunnel Questionnaire at the last follow-up.

Results: Symptom severity and functional status were improved up to half fold in both groups at final follow-up; however, there was no statistically significant clinical difference between the groups (p>0.05). There were totally six patients with paresthesia symptoms (three in each group; 4.7%), which improved in three months. Eight patients (6.3%, one in group 1 and seven in group 2, p=0.032) had dysesthesia and pillar pain.

Conclusion: Mini-open and extended open carpal tunnel release have similar clinical outcomes without any major complications.

Visual minimally invasive acupotomy is applicable for the diseases with the pathological characteristics of soft tissue injury, including disorders of spine, four limbs and joints, peripheral nerve compression and chronic soft tissues. The diseases with superior effect obtained are cervicogenic headache, lumbar disc herniation, carpal tunnel syndrome and flexor tendon stenosing tenosynovitis. Under the guidance with ultrasound, visual minimally invasive acupotomy is advantaged at preoperative diagnosis, intraoperative guidance and postoperative evaluation in clinical practice so that it is precise, safe and reliable in clinical treatment.

Objective: To evaluate the clinical efficacy of ultrasound-guided needle knife release with different pathways for carpal tunnel syndrome (CTS).

Methods: Sixty CTS patients were randomly divided into a transverse group and a longitudinal group, with 30 patients in each group. The transverse group received the needle knife release under ultrasound above and below the median nerve along the short axis, while the longitudinal group received the needle knife release under ultrasound above the median nerve along the long axis.

Background: Carpal tunnel syndrome (CTS) is a common nerve entrapment condition, and there is ongoing debate regarding the superiority of traditional open versus minimally invasive carpal tunnel surgery.

Methods: This meta-analysis reviewed six studies involving 478 patients to compare recovery and functional outcomes between the traditional longitudinal technique and the minimally invasive mini-transverse technique. The primary outcomes included the functional status scale (FSS), symptoms severity scale (SSS), pain scores, time to return to work, duration of operation, and incidence of complications.

Article Synopsis
  • Carpal tunnel syndrome (CTS) is a condition caused by pressure on the median nerve, and treatments like low-intensity laser therapy (LLLT) are being researched for their effectiveness in relief.
  • A systematic review was conducted using multiple databases to analyze the impact of LLLT on symptoms like pain, strength, and hand functionality among 13 selected randomized controlled trials.
  • Results showed that LLLT did not significantly improve pain or handgrip strength, although it had some potential benefits for hand functionality.
