Management of Recalcitrant Carpal Tunnel Syndrome.

J Am Acad Orthop Surg 2019 Apr 9. Epub 2019 Apr 9.

From the Department of Orthopaedic Surgery (Dr. Lauder, Dr. Mithani, and Dr. Leversedge), and the Department of Surgery (Dr. Mithani and Dr. Leversedge), Division of Plastic Surgery, Duke University Medical Center, Durham, NC.

Recalcitrant carpal tunnel syndrome presents a clinical challenge. Potential etiologies of persistent or recurrent symptoms after primary carpal tunnel release include incomplete nerve decompression, secondary sites of nerve compression, unrecognized anatomic variations, irreversible nerve pathology associated with chronic compression neuropathy, perineural adhesions, conditions associated with secondary nerve compression, iatrogenic nerve injury, or inaccurate preoperative diagnosis. Understanding the pertinent surgical anatomy and pathophysiology is essential toward developing an effective diagnostic and treatment strategy. Read More

Sonographic follow-up after endoscopic carpal tunnel release for severe carpal tunnel syndrome: a one-year neuroanatomical prospective observational study.

BMC Musculoskelet Disord 2019 Apr 9;20(1):157. Epub 2019 Apr 9.

The First Department of Orthopaedics, The Second Affiliated Hospital of Xi'an Jiaotong University, Xi'an Shaanxi, 710004, People's Republic of China.

Background: Endoscopic carpal tunnel release (ECTR) has been gradually adopted for the treatment of severe carpal tunnel syndrome (CTS). However, perioperative assessment of neuroanatomical parameters of median nerve, which are important determinant of median nerve recovery, has rarely been reported. This one-year prospective study aimed to investigate the natural history of the neuroanatomical morphology of the median nerve after ECTR in severe CTS patients by high-frequency ultrasonography and assess the ability of neuroanatomical measures to quantify morphological recovery of the median nerve after ECTR.

Medical Ultrasound in the Evaluation of the Carpal Tunnel: A Critical Review.

Cureus 2018 Oct 23;10(10):e3487. Epub 2018 Oct 23.

Anatomy, Histology and Embryology, Medical University of Sofia, Sofia, BGR.

The use of medical ultrasound as an imaging modality in the evaluation of the carpal tunnel syndrome has been growing. Technical progress and the introduction of new, high-quality devices and ultra-high frequency transducers with smaller dimensions have led to a better quality of acquired images and the development of new examination methodologies. The sonographic method has a number of advantages: available, non-invasive, cheaper, and allows an easier and faster evaluation and diagnosis of carpal tunnel syndrome, along with the possibility to assess various parameters of the median nerve, including its size, blood flow, and mobility.

Carpal Tunnel Syndrome and Flexor Tendon Rupture in the Wrist with Asymptomatic Scapholunate Advanced Collapse: A Case Report.

J Hand Surg Asian Pac Vol 2018 Dec;23(4):589-592

1 Department of Orthopedic Surgery, Hokkaido Saiseikai Otaru Hospital, Otaru, Japan.

We experienced a rare case of carpal tunnel syndrome and rupture of the flexor digitorum profundus tendon to the index finger with a scapholunate advanced collapse wrist. We speculated that the lunate that had extruded into the carpal tunnel compressed the median nerve and caused wear of the flexor tendon following neglected perilunate subluxation. Carpal tunnel release, opponensplasty by palmaris longus tendon transfer, and a bridge graft by a half-slip of the flexor carpi radialis tendon resulted in recovery of pinch function and improvement in numbness of the hand.

Anatomical variations of the median nerve and of the vascular-nervous structures at the wrist.

J Biol Regul Homeost Agents 2018 Sep-Oct;32(5):1285-1290

Department of Sensory Organs "Sapienza" University of Rome, Italy.

Three cases of anatomical variation of the median nerve at the wrist found during our surgical activity led us to take the opportunity to expose anatomical variations by reviewing already published reviews. Consequently, on the basis of anatomical studies, clinical reports and imaging, as a result of careful examination of the published literature, it has been observed that the interventions in such anatomical area must take into account these variations. In particular, the most performed procedure is the lysis of the transverse carpal ligament (TCL), which is not free from complications. Read More

Ultrasound as a diagnostic tool in the investigation of patients with carpal tunnel syndrome.

Eur J Transl Myol 2018 Apr 24;28(2):7380. Epub 2018 Apr 24.

Mashhad University of Medical Sciences, Mashhad, Iran.

Carpal tunnel syndrome (CTS) is reveled to be the most common peripheral nerve entrapment syndrome, estimating for 90% of all compressive. The diagnosis of CTS is based on the use of clinical criteria and imaging technique tests such as ultrasonography (US) and magnetic resonance imaging (MRI). US is a time-saving method in the diagnosis of CTS, which induces less discomfort to the patient and may be a more cost-effective approach to confirm clinical suspicion of this syndrome . Read More

Bilateral Bifid Median Nerve with Bilateral Carpal Tunnel Syndrome: An Atypical Presentation, a Rare Cause and a Familiar Disease.

J Hand Surg Asian Pac Vol 2018 Jun;23(2):274-277

† Hand and Microsurgery Unit, Kasturba Medical College, MAHE, Karnataka, India.

We report a case of bilateral carpal tunnel syndrome (CTS) with bilateral bifid median nerve (BMN) without a persistent median artery diagnosed by clinical examination, NCV and Ultrasonography. Bilateral BMN to produce bilateral CTS is extremely rare and is contrary to the popular classifications which state that BMN without persistent median artery or its anomalies will not produce CTS. Ultrasonogram is of additional help to identify such aberrations in the median nerve to prevent iatrogenic injuries during carpal tunnel decompression. Read More

Comparison of two ways of altering carpal tunnel pressure with ultrasound surface wave elastography.

J Biomech 2018 06 12;74:197-201. Epub 2018 Apr 12.

Division of Orthopedic Research, Department of Orthopedic Surgery, Mayo Clinic, Rochester, MN 55905, USA. Electronic address:

Higher carpal tunnel pressure is related to the development of carpal tunnel syndrome. Currently, the measurement of carpal tunnel pressure is invasive and therefore, a noninvasive technique is needed. We previously demonstrated that speed of wave propagation through a tendon in the carpal tunnel measured by ultrasound elastography could be used as an indicator of carpal tunnel pressure in a cadaveric model, in which a balloon had to be inserted into the carpal tunnel to adjust the carpal tunnel pressure.

ACR Appropriateness Criteria Chronic Wrist Pain.

J Am Coll Radiol 2018 May;15(5S):S39-S55

Specialty Chair, Mayo Clinic, Phoenix, Arizona.

Radiographs are indicated as the first imaging test in all patients with chronic wrist pain, regardless of the suspected diagnosis. When radiographs are normal or equivocal, advanced imaging with MRI (without or without intravenous contrast or following arthrography), CT (usually without contrast), and ultrasound each has a role in establishing a diagnosis. Furthermore, these examinations may contribute to staging disease, treatment planning, and prognostication, even when radiographs are diagnostic of a specific condition. Read More
