Open Carpal Tunnel Release

Conventional open carpal tunnel release surgery is one of most successful procedures in hand surgery and has been demonstrated to be an effective treatment for carpal tunnel syndrome. However, a known sequelae in some individuals who undergo the procedure is “pillar” pain. In an effort to avoid this condition and help people return to work more quickly, the endoscopic technique was developed. Endoscopic carpal tunnel release offers a minimally invasive alternative to other traditional techniques with similar outcomes. By placing the incision proximal to the transverse carpal ligament there is potential for decreased scar sensitivity and pillar pain. The technique is technically demanding. The superficial palmar arch and common digital nerve to the ring and middle fingers are at risk for injury during the procedure. With adherence to anatomical landmarks and the proper visualization, the surgery may be safely performed.

An extensive review of published articles on the subject of endoscopic carpal tunnel release surgery is presented, encompassing six endoscopic techniques used to treat carpal tunnel syndrome. Since the first report in 1987, 7091 patients have undergone 8068 operations. The overall success rate has been 96.52%, with a complication rate of 2.67% and a failure rate of 2.61%. The mean time to return to work in patients not receiving Workers' Compensation was 17.8 days, ranging between 10.8 and 22.3 days. The most common complications were transient paresthesias of the ulnar and median nerves. Other complications included superficial palmar arch injuries, reflex sympathetic dystrophy, flexor tendon lacerations, and incomplete transverse carpal ligament division. All studies in which open and endoscopic techniques were compared reported that patients in the latter group experienced significantly less pain and returned to work and activities of daily living earlier. The reported success and complication rates of endoscopic carpal tunnel release surgery are similar to those for standard open procedures. Endoscopic techniques and outcomes are discussed.

Endoscopic carpal tunnel release is increasingly performed to treat median nerve entrapment neuropathy at the transverse carpal ligament. Proponents of these procedures claim that there are early postoperative advantages to be gained by the patient in the form of decreased pain and weakness, thus facilitating an earlier return to function. However, serious complications associated with the use of these techniques have been reported, especially during the surgeon's purported initial steep learning curve. A prospective analysis of the authors' first 51 cases using a two-portal endoscopic technique was conducted to determine whether these learning curve complications occurred. The authors did experience a learning curve; however, it was not significant. They encountered no serious complications and patient satisfaction was very high. It is concluded that the procedure is relatively easy to learn and safe to perform.

Recurrent carpal tunnel syndrome from various causes has been shown to occur in up to 19% of patients. Endoscopic carpal tunnel release has been used to decompress the median nerve in carpal tunnel syndrome for many years. However, endoscopic release for recurrent carpal tunnel syndrome after previous surgical release has not been reported. Nine hands in six patients had recurrent carpal tunnel syndrome five to 20 years after previous open carpal tunnel release. All the cases were successfully treated with endoscopic release.

Carpal Tunnel Release Surgery

Segmental carpal tunnel pressure was measured in 12 hands of 11 idiopathic carpal tunnel syndrome patients before and after two-portal endoscopic carpal tunnel release. We aimed to determine at which part of the carpal tunnel the median nerve could be compressed, and to evaluate whether carpal tunnel pressure could be reduced sufficiently at all segments of the carpal tunnel after the surgery. Pressure measurements were performed using a pressure guide wire. The site with the highest pressure corresponded to the area around the hamate hook; the pressure in the area distal to the flexor retinaculum could be pathogenically high (more than 30 mmHg) before the surgery. The two-portal endoscopic carpal tunnel release achieved sufficient pressure reduction in all segments of the carpal tunnel when the flexor retinaculum and the fibrous structure between the flexor retinaculum and the palmar aponeurosis were completely released.

Introduction: Carpal tunnel syndrome is the most common compression neuropathy in clinical practice and is also the most extensively studied. In Mini-open carpal tunnel release, the transverse carpal ligament is transected using a small open cut at the volar aspect of the proximal palm. The objectives of this study were to determine the functional outcome of mini-open carpal tunnel release procedure, to use the Boston Questionnaire to determine the functional outcome following mini open carpal tunnel release which includes pain, numbness, weakness and fine hand activities. Methods: This descriptive cross-sectional was conducted in National After informed consent, the cases who meet the informed criteria were examined and relevant details were filled up in the proforma preoperatively and two weeks post-operatively. Assessment of the patient’s symptom severity and functional status was done with the Boston questionnaire. Results: CTS was most common in the age group of 25-29 years (36.36%) and was predominant in housewives (18.20%). Mean symptom severity scores per person improved from 3.11 pre-operatively to 1.12 post-operatively. Mean functional status scores per person improved from 2.65 pre-operatively to 1.03 post-operatively. There was a statistically significant improvement in postoperative outcomes in our population. Conclusions: The findings in this study indicate that mini-open carpal tunnel release has a good functional outcome.

Portal Technique

During a 4-year period, a total of 784 wrists of 640 patients were treated using a modified Chow's extrabursal dual portal endoscopic technique. All surgeries were performed under local anesthesia. A 1-cm incision was marked 1 - 2 cm proximal to the distal wrist crease, in the midline, ulnar to the palmaris longus. A distal portal was established along a line bisecting an angle created by the intersection of the ulnar border of the abducted thumb and the third web space. An obturator and cannula assembly were inserted under the portal, and three blades were used to cut under endoscopic vision. Subjective results showed that 706 hands (90%) had a reduction in the severity of pain after carpal tunnel release, 706 hands (90%) had a reduction in the severity of paresthesia and 729 hands (93%) had a reduction in the severity of numbness. Nocturnal pain and paresthesia were relieved in 745 cases (95%). Compared with the conventional open carpal tunnel release, less postoperative pain and faster recovery have been reported following endoscopic carpal tunnel release. This study suggests that extrabursal dual portal technique is a safe and reliable treatment option for carpal tunnel syndrome with a high success rate.

Forty hands of 36 patients who had undergone endoscopic carpal tunnel release (ECTR), utilising Chow's two-portal technique after being diagnosed with idiopathic carpal tunnel syndrome, were subjected to longitudinal median nerve conduction studies. The distal motor latency (DML) was examined pre-operatively on all the hands, which were re-examined at the post-operative 1st, 3rd, 6th and 12th months. Rapid improvement of DML was observed post-operatively in the first three months. These improvements patterns are not much different from those after open carpal tunnel release (OCTR) reported in the literatures. We consider that the data reported herein can be used as standards of DML course after ECTR.

Abstract Background The purpose of the study was to examine the coverage of thenar and hypothenar muscles on the transverse carpal ligament (TCL) in the radioulnar direction through in vivo ultrasound imaging of the carpal tunnel. We hypothesized that the TCL distance covered by the thenar muscle would be greater than that by the hypothenar muscle, and that total muscle coverage on the TCL would be greater than the TCL-alone region. Methods Ultrasound videos of human wrist were collected on 20 healthy subjects. Automated algorithms were used to extract the distal cross-sectional image of the trapezium-hamate level. Manual tracing of the anatomical features was conducted. Results Thenar muscles covered a significantly larger distance (11.9 ± 1.8 mm) as compared with hypothenar muscles (1.7 ± 0.8 mm) (p < 0.001). The TCL covered by thenar and hypothenar muscles was greater than the TCL-alone length (p < 0.001). The thenar and hypothenar muscle coverage on the TCL, as normalized to the total TCL length, was 61.0 ± 7.5%. Conclusions More than 50% of the TCL at the distal carpal tunnel is covered by thenar and hypothenar muscles. Knowledge of muscular attachments to the TCL improves our understanding of carpal tunnel syndrome etiology and can guide carpal tunnel release surgery.
