Muscle activity analysis using electromyography during sensory collapse test: An experimental case report.

A 48-year-old right-handed male surgeon complained of finger numbness, pain, cramps and weakness of 2 years' progression, without improvement after 2 carpal tunnel corticosteroid injections and splinting. The patient was diagnosed with lacertus syndrome with Hagert's triad. Sensory collapse test was positive, but the sensations during the test were not consistent with the literature.

Lacertus syndrome: recent advances.

Lacertus syndrome consists in proximal median nerve entrapment with median nerve compression at the lacertus fibrosus, causing hand weakness and fatigue, forearm pain and occasional numbness. Recent advances emphasized the importance of clinical examination, due to limitations in electromyographic diagnosis and delayed diagnosis. The Hagert clinical triad, lacertus notch sign, lacertus antagonist test and taping help accurate diagnosis.

Description of WALANT technique in open bone and ligament wrist surgery.

The gold-standard for bone, ligament and joint surgery in the wrist is locoregional anesthesia in most countries. Wide-Awake Local Anesthesia No Tourniquet (WALANT) is commonly used for simple soft-tissue hand surgery procedures such as carpal tunnel or trigger finger release, and can now also be safely used in procedures such as proximal row carpectomy, scapholunate ligament repair or partial wrist fusion, to name but a few. This article describes the use of WALANT for complex surgery in the wrist.

From teaching to practice: Evaluating the impact of an upper-limb ultrasound surgery diploma on surgical practice.

Objectives: This study evaluates the impact of an upper-limb ultrasound surgery diploma on surgical practices, specifically assessing how this specialized training influences the adoption and application of ultrasound techniques in upper limb surgeries.

Material And Methods: A comprehensive survey was conducted from August to November 2023, targeting individuals who completed the upper-limb ultrasound surgery diploma program between 2013 and 2023. The survey, distributed online, comprised 31 questions spanning demographic information, professional background, specifics about the diploma program, motivations for pursuing the diploma, post-diploma practices, challenges faced, and financing of ultrasound equipment.

Wrist Hemiarthroplasty of Irreparable Distal Radius Fracture under Wide-Awake Local Anesthetic and No Tourniquet.

Distal radius fractures (DRF) are common in elderly patients and the incidence continues to increase with the aging of the population. For irreparable fractures in the elderly, treatment with a reduction cast leads to unreliable results and frequent complications when treated with an anterior plate. Recent studies on hemiarthroplasty for elderly complex wrist fractures have resulted in good clinical and radiologic outcomes, as well as high satisfaction rates.

Percutaneous Ultrasound-Guided Release of the Lacertus Fibrosus for Median Nerve Entrapment at the Elbow.

Purpose: The aim of this technical note is to present a microinvasive percutaneous ultrasound-guided release of the lacertus fibrosus of the biceps brachii for pronator syndrome, i.e., entrapment of the median nerve at the elbow.

Flexor Tendons Sonography.

Ultrasonography is the best examination to explore the flexor tendons anatomy and disorders from the wrist to the digit. It is the only dynamic and comparative tool easily accessible for the surgeon. Indeed, ultrasonography is always available in all the departments of your hospital.

Ultrasound-Guided de Quervain's Tendon Release, Feasibility, and First Outcomes.

 de Quervain's syndrome is one of the main tendonitis of the wrist. The hypothesis of authors was that de Quervain's syndrome could be successfully treated with a specific ultrasound-guided percutaneous procedure, as it is for trigger finger.  Identification of the subcompartmentalization of the first extensor compartment was performed first, using the Hiranuma's classification, prior to the surgery.

Arthroscopic Treatment of Symptomatic Congenital Lunotriquetral Coalition.

Symptomatic lunotriquetral coalition is very rare and need open surgery after failure of conservative treatment. We report a case of a symptomatic congenital lunotriquetral coalition type 1 according to the Minaar classification, at the left wrist of a 14-year-old boy. We performed an arthroscopic treatment with two compression screws and without cancellous bone grafting.

Ultrasonography for the orthopaedic surgeon.

The recent development of high-frequency ultrasonography transducers has provided better accuracy and improved the ability to image more superficial body structures. Ultrasonography is a widely available, inexpensive, comparative, and dynamic imaging technique that involves no radiation exposure and has no other adverse effects. Ultrasonography must always be combined with a medical history, physical examination, and radiographic assessment.

"Onycholemmal carcinoma." An unusual case with apocrine and sebaceous differentiation. Are these tumors a microcystic nail bed carcinoma?

Subungual malignant epithelial tumors with tricholemmal keratinization have rarely been described as "malignant proliferating onycholemmal cyst" and "onycholemmal carcinoma (OC)." We report an additional case of a slow growing OC occurring on the middle finger of a 58-year-old man, which was unusual as it showed sebaceous-apocrine differentiation, in addition to a nail bed carcinoma with tricholemmal microcysts. We therefore consider the descriptive term of microcystic nail bed carcinoma more appropriate than OC.

A novel pyrolytic carbon implant for hallux rigidus: a cadaveric study.

Background: The aim of this cadaveric study was to assess the technical feasibility of inserting a novel interpositional pyrolytic carbon coated implant in the first MTP joint, determine the best surgical procedure for the implantation, and evaluate the dynamic behavior of the joint after surgery.

Methods: The marble implant was inserted in the first metatarsophalangeal joint of five pairs of cadaveric feet using two different surgical approaches, dorsal and medial, for each pair. The stability and mobility of the feet before and after implantation, as well as the relationship between the implant and the sesamoids, were assessed by static and dynamic fluoroscopy.

End-to-side neurorrhaphy for median nerve repair after elbow tumor resection: case report.

We report a case of a median to ulnar end-to-side neurorrhaphy with epineurectomy but without fascicular donor nerve section. Surgery was performed for the curative treatment of an elbow synovial sarcoma at the level of the elbow that necessitated resection of 10 cm of the median nerve. The patient was followed up for 24 months.
