Ulnar/cubital tunnel syndrome is the second most common compressive neuropathy of the upper limb. Permanent location of the ulnar nerve anterior to the medial epicondyle is extremely rare, with only five cases reported in the literature. Using ultrasound elastography and diffusion tensor imaging with fiber tractography, we diagnosed a case in which...

In humans, bipartite scaphoid still does not differentiate clearly from traumatic non-union of the scaphoid. To aid diagnosis, we sought to analyze the main geometrical similarities among bipartite scaphoids from primate species with fused and unfused scaphoid centrales. Four human embryos, four cases of adult humans with bipartite scaphoid, twelve...

We investigated the role of three-dimensional (3-D) CT in the diagnosis and management of four bipartite scaphoids in three patients. We computed the volume ratio, moment of inertia ratio and direction vector from the centroid of the scaphoid to the os centrale carpi. We found that the os centrale carpi was always smaller than the scaphoid and show...

Biomimicry consists in imitating nature to solve complex human problems. The hand surgeon usually tries to copy and recreate the structure-to-function and function-to-control relationships of the native tissues after damage. With its exceptional structure and biomechanics, the flexor digitorum superficialis (FDS) has been an important source of ins...

Purpose The flexor carpi radialis brevis (FCRB) is a supernumerary musculotendinous structure of the wrist that has been the focus of some interest in the last decade. While its anatomy is well known, its in vivo function remains unknown as it has never been studied. Methods Eleven cases of FCRB underwent a multimodal ultrasound consisting of B-mo...
Article
Purpose The spiral oblique retinacular ligament (SORL) procedure acts as a dynamic tenodesis to restore distal interphalangeal joint (DIP) extension and restrain proximal interphalangeal hyperextension. Despite the ingenious technique based on the oblique retinacular ligament anatomy, obtaining strong internal fixation remains an issue during the S...
Article
The choice of the donor tendon in tendon reconstruction of the hand theoretically influences the results of the surgery because of the interactions of its structure with the healing process. The objective of our study was to specify the surgical bases of vascularized extensor indicis proprius (EIP) in tendon reconstruction of the hand and to presen...

Wide awake local anesthesia no tourniquet (WALANT) hand surgery is a rapidly growing in popularity. WALANT has been used by hand surgeons when operating on bones, tendons, ligaments, nerve entrapments. We offer a case report of the first case in the literature describing WALANT technique when performing trapeziometacarpal joint arthroplasty with pr...

Metacarpal nonunion after closed fracture is uncommon. Tough atrophic and hypovascular nonunions happen mostly in transverse diaphyseal fractures. It usually occurs after bone loss or expansive removal of the periost. Patients with this condition often present with persistant pain, loss of motion, or loss of strength. Clinical and surgical handling...

Successful Plastic Surgery Residency training is subjected to evolving society pressure of lower hourly work weeks imposed by external committees, labor laws, and increased public awareness of patient care quality. Although innovative measures for simulation training of surgery are appearing, there is also the realization that basic anatomy trainin...

Fingertip response to trauma represents a fascinating example of tissue regeneration. Regeneration derives from proliferative mesenchymal cells (blastema) that subsequently differentiate into soft and skeletal tissues. Clinically, conservative treatment of the amputated fingertip under occlusive dressing can shift the response to tissue loss from a...

Closed tendon avulsion of both flexor tendons in the same finger is an extremely rare condition. We encountered the case of a patient who presented a rupture of the flexor digitorum profundus in zone 1 and flexor digitorum superficialis in zone 3 in the little finger. This occurrence has not been reported previously. We hereby present our case, mak...

... SWE confirmed the anterior location of the ulnar nerve relative to the rotation axis of the elbow, with a decreased tension in the ulnar nerve during elbow flexion: the values of the shear elastic modulus in the ulnar nerve decreased from 107.2 to 79.1 kPa with elbow flexion. These shear elastic modulus values were comparable to those recently reported in patients before and after anterior transposition of the ulnar nerve [5]. Due to the absence of extrinsic compression factors in this anterior nerve location, excessive friction and stretching are other potential mechanisms to consider. ...
... Innervation of the FCRB is provided by the anterior interosseous nerve, and feeding is supplied by the radial artery 5,13,14 . The FCRB is a striated skeletal muscle and plays a role in voluntary wrist flexion 15 . 16 found a presence of the FCRB of 1.7% among 225 cadavers, and Mimura et al. 14 calculated a ratio of 1.6% based on the MR images of 379 people with carpal tunnel syndrome. ...
... 3e5 Although a pain-free outcome with a low complication rate can be attained with IP arthrodesis, stiffness of the joint leads to restricted dexterity, especially during pinching and picking up of small objects. 6 To preserve the range of motion (ROM) of the joint, joint replacement with implant arthroplasty is an alternative, as reported for the distal IP joints of the fingers. 7,8 However, to date, only 3 reports have been published describing joint replacement for the thumb IP joint. ...

... The corona virus disease pandemic of 2019 (COVID- 19) has had a huge impact on anatomy teaching [11]. Although cadaveric dissection is crucial for acquiring skills [10] [18], it was thought that students' exposure with dissection had reduced prior to the epidemic. [27] stated that cadaveric dissection anatomy classes have declined in many medical schools since the quantity of donated bodies has far outstripped the expanding number of students, notably during the pandemic, however the situation may vary by region and country. ...
... Plants can be grafted on various scions, and a successful union is also a form of wound repair and thus regeneration. Another type of regeneration is organ completion, as seen in animals as a fingertip regeneration or in plants as root tip regeneration [10][11][12][13]. In this type of regeneration, the organ that was slightly amputated can repair itself. ...
