Ultrasound Assessment

Sensory changes are common manifestations of nerve complications of carpal tunnel surgery. Division or contusion of a superficial communicating branch between the median nerve and the ulnar nerve, the communicating branch of Berrettini, can explain these symptoms. The aim of this study was to describe the potential value of high-resolution sonography to examine this branch. We conducted a study on eight fresh cadaver hands. An ultrasound assessment of the communicating branch of Berrettini, accompanied by an injection of methylene blue, was performed by a senior radiologist. Subsequent dissections confirmed that the eight guided ultrasound injections allowed the methylene blue to be placed around the origin and termination of the communicating branch of Berrettini. This study extends the limits of ultrasound both in the postoperative diagnosis of potential nerve complications and its possible use in ultrasound-guided carpal tunnel release.

Purpose: Supraretinacular endoscopic carpal tunnel release (SRECTR) is a technique in which an endoscope is inserted superficial to the flexor retinaculum through a subcutaneous tunnel. The benefits of this method include a clear view for the surgeon and absence of median nerve compression. Surgeons can operate with a familiar view of the flexor retinaculum and median nerve downward, similar to open surgery. This study aimed to investigate the learning curve for SRECTR, an alternate method for carpal tunnel release, and evaluate its complications and the functional outcomes using a disposable commercial kit. Methods: We examined the open conversion rates and complications associated with SRECTR in 200 consecutive patients performed by two surgeons. We compared the operative time operated by a single surgeon. We evaluated outcomes in 191 patients according to Kelly’s grading system. Patients’ mean follow-up period was 12.7 months. Results: Nine patients required conversion to open surgery. There were no injuries to the nerves and tendons and no hematoma or incomplete dissection of the flexor retinaculum. The operative times varied between 11 and 34 minutes. We obtained the following results based on Kelly’s grading of outcomes: excellent in 116, good in 59, fair in 13, and poor in 3 patients. Conclusions: We found no patients with neurapraxia, major nerve injury, flexor tendon injury, superficial palmar arch injury, and hematoma. Although there was a learning curve associated with SRECTR, we performed 200 consecutive cases without neurovascular complications. This method may be a safe alternative to minimally invasive carpal tunnel surgery.

Meta Analyses

AbstractCarpal tunnel syndrome (CTS) may be treated surgically if medical treatment fails. The classical approach involves release of the flexor retinaculum by endoscopic or open surgery. Meta-analyses have shown that the risk of nerve injury may be higher with endoscopic treatment. The recent contribution of ultrasound to the diagnosis and therapeutic management of CTS opens new perspectives. Ultrasound-guided carpal tunnel release via a minimally invasive approach enables the whole operation to be performed as a percutaneous radiological procedure. The advantages are a smaller incision compared with classical techniques; great safety during the procedure by visualization of anatomic structures, particularly variations in the median nerve; and realization of the procedure under local anesthesia. These advantages lead to a reduction in postsurgical sequelae and more rapid resumption of daily activities and work. Dressings are removed by the third day postsurgery. Recent studies seem to confirm the medical, economic, and aesthetic benefits of this new approach.

Background and objectives Distal upper extremity surgery is commonly performed under regional anaesthesia, including intravenous regional anaesthesia (IVRA) and ultrasound-guided forearm nerve block. This study aimed to investigate if ultrasound-guided forearm nerve block is superior to forearm IVRA in producing a surgical block in patients undergoing carpal tunnel release. Methods In this observer-blinded, randomized controlled superiority trial, 100 patients undergoing carpal tunnel release were randomized to receive ultrasound-guided forearm nerve block (n = 50) or forearm IVRA (n = 50). The primary outcome was anaesthetic efficacy evaluated by classifying the blocks as complete vs incomplete. Complete anaesthesia was defined as total sensory block, incomplete anaesthesia as mild pain requiring more analgesics or need of general anaesthesia. Pain intensity on a numeric rating scale (0–10) was recorded. Surgeon satisfaction with hemostasis, surgical time, and OR stay time were recorded. Patient satisfaction with the quality of the block was assessed at POD 1. Results In total, 43 (86%) of the forearm nerve blocks were evaluated as complete, compared to 33 (66%) of the forearm IVRA (p = 0.019). After the forearm nerve block, pain intensity was lower at discharge (-1.76 points lower, 95% CI (-2.92, -0.59), p = 0.0006) compared to patients treated with forearm IVRA. No differences in pain experienced at the start of the surgery, during surgery, and at POD1, nor in surgical time or total OR stay were observed between groups. Surgeon (p = 0.0016) and patient satisfaction (p = 0.0023) were slightly higher after forearm nerve block. Conclusion An ultrasound-guided forearm nerve block is superior compared to forearm IVRA in providing a surgical block in patients undergoing carpal tunnel release. Trial registration This trial was registered as NCT03411551.

This randomized, double-blinded study assessed the effectiveness of a topical anaesthetic, eutectic mixture of local anaesthetics (EMLA), in reducing pain associated with carpal tunnel release performed under local anaesthetic. Fifty-six patients undergoing carpal tunnel release under local anaesthetic were randomized into either EMLA ( n=29) or placebo ( n=27) groups. Visual analogue pain scores were obtained for needle insertion, injection of anaesthetic and surgery itself. Pain scores were significantly less for needle insertion ( P=0.001) and injection of anaesthetic ( P=0.0005). Scores related to surgery were also lower in the EMLA group, but this did not reach statistical significance.

Background: Health literacy is the ability of a patient to understand their medical condition. The purpose of this investigation is to determine whether patients are able to obtain an elementary understanding of the fundamental principles of carpal tunnel release and the postoperative instructions after going through the process of informed consent and being provided an additional standardized postoperative instruction document. Our hypothesis is that patients will lack an understanding of these principles and, therefore, will be at risk for being noncompliant in their postoperative care. Methods: Fifty patients with a diagnosis of carpal tunnel surgery who elected to undergo carpal tunnel release alone were enrolled. A standardized education process was performed. Patients completed the questionnaire at their postoperative visit. Results: The average percentage of correct answers was 75.8% (8.34 out of 11 correct). Fisher exact test analysis demonstrated that patients with a lower education level were less likely to know how long it takes for their preoperative symptoms to resolve ( P = .0071), and they were less likely to correctly choose all of the important elements of postoperative care during the first week after surgery ( P = .022). Conclusions: Although we made efforts to help patients achieve health literacy in carpal tunnel surgery, we found that patients continued to lack comprehension of pertinent components of carpal tunnel surgery, particularly understanding the involved anatomy.

Open Carpal Tunnel Release

This study examines the variations in incisions and postoperative protocol of open carpal tunnel release. A questionnaire was distributed to 65 hand surgeons. Respondents were asked to draw their preferred incision on original photocopies of the same palm. The results were measured against standard anatomical landmarks (thenar crease, vertical axis of the third web space, proximal palmar crease and the distal wrist crease). The participants were also asked to answer questions concerning their postoperative protocols. Demographics of the cohort, as well as the variations in incisions and postoperative management, were analyzed. Significant variations existed in the length and location of the incision in the palm. The differences in postoperative care in this cohort of surgeons were less significant.

Portal Technique

A new one-portal technique for endoscopic carpal tunnel release (ECTR) is introduced with its clinical results. The incision is made at the palmar aspect of file hand. A custom-made glass tube with a groove is inserted, and under endoscope observation, a meniscus knife is pushed forward along the groove to release the flexor retinaculum. This new technique has been studied in ten fresh cadaver hands and used in 123 patients' hands. Results of the cadaver study showed that the flexor retinaculum was released completely in all ten hands. No injuries to tendons, nerves, or arteries were noted. In one case the cotton tip was lost from the stick. All clinical releases were performed uneventfully except for three cases of neuropraxia of the digital nerve of the radial side of the ring finger, one laceration of the motor branch of the median nerve, one mild infection, one loss of cotton tip from the cotton swab stick, and one case of chipping of the glass tube. The case with the laceration of the motor branch of the median nerve occurred early in the series and required the conventional open incision to repair the nerve. The cases with loss of cotton from the stick and chipping of the tube also required a conventional incision to remove the cotton and glass chip. Advantages of this one-portal technique with the glass tube include less scar tenderness than with two-portal techniques, decreased risk of injury to the superficial palmar arch and ulnar nerve because of the distal approach, a view of pathology in the carpal tunnel through the glass tube, and confirmation of release of the flexor retinaculum.
