Venous system mapping of the digits and the hand: An anatomical study and potential surgical applications.

Background: Venous anatomy of the digits and the hand is poorly reported in the literature compared to arterial anatomy. While knowledge of the venous anatomy is crucial to ensure safe skin incisions, skin flap design, or blood return restoration for digital replantations, data in anatomical and clinical textbooks are rather limited. The purpose of this anatomical study was to describe the venous anatomy of the digits and the hand.

Thoracic Outlet Syndrome: Diagnostic Accuracy of MRI.

Background: Thoracic outlet syndrome (TOS) is challenging to diagnose, as the physical findings and investigations lack sensitivity and/or specificity. Magnetic resonance imaging (MRI) with dynamic manoeuvres can rule out a tumour and detect anatomical abnormalities potentially responsible for compression. The objective of this study was to assess the sensitivity and specificity of MRI for identifying anatomical structures responsible for compression in TOS, using intra-operative findings as the diagnostic reference standard.

Use of an index finger as a bank in thumb reconstruction after tumor resection: About one case.

The use of a "bank finger" by its very nature is almost exclusively reserved for the management of traumatic hand injuries. Here, we described one case of thumb reconstruction using the patient's index finger as a "bank finger" after the excision of a grade II malignant fibrous histiocytoma.

Experimental determination of the elbow's center of rotation using the VICON™ optoelectronic motion capture system.

Purpose: Knowledge of elbow kinematics is essential to better understand this joint. There is currently no reliable dynamic method to accurately study the elbow joint in a non-invasive manner. The goal of this study was to implement an accurate protocol to study in vivo elbow kinematics using a VICON™ optoelectronic motion analysis system.

Three-Corner Arthrodesis With Scaphoid and Triquetrum Excision for Wrist Arthritis.

Purpose: To report the clinical and radiographic results of a consecutive series of patients who underwent the 3-corner arthrodesis (3CA) (arthrodesis of capitate, hamate, and lunate with scaphoid and triquetrum excision) procedure for wrist arthritis.

Methods: This was a retrospective study of 30 consecutive patients who underwent a 3CA between 1994 and 2008. The indications were painful wrist osteoarthritis due to stage 2 or 3 scapholunate advanced collapse, scaphoid nonunion advanced collapse, or scaphoid chondrocalcinosis advanced collapse wrists.

Comparative morphometry of the antebrachial and crural interosseous membranes: preliminary study for the use of the crural interosseous membrane in the surgical repair of the antebrachial interosseous membrane tears.

Introduction: Traumatic tears of the antebrachial interosseous membrane (AIOM) on its whole length are difficult to treat, particularly in the Essex-Lopresti syndrome. The number of ligamentoplasty techniques described in the literature witnesses the difficulty of its reconstruction and the absence of reliable and satisfying procedure. The aim of this study was to explore a new way of treatment, which consists in replacing the AIOM by the crural interosseous membrane (CIOM), harvested from the same patient.

The supinator muscle: anatomical bases for deep branch of the radial nerve entrapment.

Purpose: Our goals were to carry out an anatomical description of the internal architecture of the supinator muscle in order to describe potentially compressive structures for the deep branch of the radial nerve (DBRN) and to establish reference landmarks for the surgical treatment of radial tunnel syndrome.

Methods: Thirty upper limbs were dissected. The pennation angle of proximal and distal arcades of the supinator to the radial shaft axis was measured.

Entrapment neuropathies of the shoulder.

Entrapment neuropathies are a rare but presumably underdiagnosed cause of shoulder pain and painful instability. Radiologists must be aware of the clinical presentations and imaging features of these neuropathies because they may be the first to suggest these diagnoses. In this article, instead of a classical nerve-by-nerve approach, entrapment neuropathies are deciphered according to the clinical situation: which anatomic structures may be involved, how to explore them, which imaging abnormalities can be expected, how to manage differential diagnoses, and which therapeutic options can be considered.

Running activity after hip resurfacing arthroplasty: a prospective study.

Background: The ability to return to sports activities (especially running) after hip resurfacing arthroplasty seems to be very important for young and active patients who have developed osteoarthritis.

Purpose: To assess the quality of return to sports after hip resurfacing arthroplasty by examining the time spent running, weekly mileage, and the possibility of returning to competition in a series of patients.

Study Design: Case series; Level of evidence, 4.

Peripheral tumor and tumor-like neurogenic lesions.

Neoplasms of neurogenic origin account for about 12% of all benign and 8% of all malignant soft tissue neoplasms. Traumatic neuroma, Morton neuroma, lipomatosis of a nerve, nerve sheath ganglion, perineurioma, benign and malignant peripheral nerve sheath tumors (PNST) are included in this group of pathologies. Clinical and radiologic evaluation of patients with neurogenic tumors and pseudotumors often reveals distinctive features.

Anatomical bases of the free posterior brachial fascial flap.

Purpose: Fascias can be used for reconstruction of gliding surfaces of upper and lower extremities or when thin, pliable coverage is required. Free large and well-vascularised fascial flaps are not very many and harvesting is seldom onto upper limb. The aim of this work was to study blood supply of the posterior brachial fascia in order to define the anatomical bases of a new free fascial flap.

Adrenal gland hypertrophy in a case of homolateral renal agenesis: case report with special emphasis on adrenal blood supply.

Hypertrophic suprarenal gland is an anomaly which can lead to serious complications during adrenalectomy under endoscopy because of abnormal veins of the retroperitoneum. The authors report a rare dissection of a male which presented with this anomaly in a case of homolateral renal agenesis, highlighting this left pseudorenal vein. No abnormality of the genital tract was found.

Sonographic assessment of the lateral femoral cutaneous nerve.

Purpose: To evaluate the ability of high-frequency sonography to evaluate the lateral femoral cutaneous nerve (LFCN).

Methods: A cadaveric study was performed on 5 cadavers to outline the normal course of the LFCN. Next, 37 LFCNs in 21 volunteers were evaluated via sonography with a 5-13-MHz linear-array transducer.
