We describe three instances of ruptured flexor pollicis longus tendons due to bony spurs within the carpal tunnel. In each case, the bony spur was excised and the remaining exposed bone was covered with a flap of flexor retinaculum.

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.

Flexor Pollicis Longus Tendon

A case is described in which an anomalous insertion of the flexor pollicis longus tendon into the region of the carpal tunnel caused limited active flexion of the thumb in a child. This is the first reported case of this anomaly in which an apparent familial relationship has been noted, and the first reported case in the Caucasian race. Two similar cases in Japanese have been described. Abnormal insertion of a portion of the flexor pollicis longus must be included in the differential diagnosis of inadequate thumb flexion.

Introduction: Aberrant positioning of the ulnar nerve volar to the transverse carpal ligament is a rare anatomic variation.Case Presentation: We present the case of a 55-year-old female with unique ulnar nerve anatomy that was discovered introperatively during carpal tunnel release.  The ulnar nerve was running directly adjacent to the median nerve in the distal forearm and as the median nerve traversed dorsal to the transverse carpal ligament (flexor retinaculum) to enter the carpal tunnel the ulnar nerve continued directly volar to this structure before angling towards Guyon’s Canal.  The unique ulnar nerve anatomy was successfully identified, carefully dissected and managed with a successful patient outcome.Conclusion: Variations of the anatomy at the level of the carpal tunnel are rare but do exist.  Awareness of these anatomic variations and adequate visualization of the ulnar nerve along with the surrounding structures is crucial to avoid iatrogenic injuries during carpal tunnel release.

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.

Infusion Technique

The roof of the carpal tunnel (or canal) consists of the distal portion of the flexor retinaculum, the flexor retinaculum (or the transverse carpal ligament) and the proximal portion of the flexor retinaculum. We tried to determine which anatomical structures were relevant to complete endoscopic carpal tunnel decompression in long-term haemodialysis patients with carpal tunnel syndrome. Carpal tunnel pressure was measured using the continuous infusion technique before and after endoscopic release of the flexor retinaculum, distal portion of the flexor retinaculum and the proximal portion of the flexor retinaculum respectively in 257 hands. We concluded that release of the distal portion of the flexor retinaculum, in addition to the flexor retinaculum, is essential for complete carpal tunnel decompression in long-term haemodialysis patients.
