Vascular supply of the radial nerve and its terminal branches: an anatomical study.

Purpose: The aim of this cadaveric study was to further describe the vascular supply of the radial, posterior interosseous and superficial radial nerves.

Methods: 11 cadaveric upper limbs, injected with colored latex, were dissected. Vascular afferents to the radial nerve, superficial radial nerve (SRN) and posterior interosseous nerve (PIN) were described and located.

Long-term outcome of fibula flaps in complex limb reconstruction compared to alternative procedures, a median follow up of 41 months.

Introduction: Complex open long bone fractures present a multidisciplinary surgical challenge. Various treatment options are discussed with no consensus. Fibula flaps (FF) are frequently used in maxillofacial surgery, however their use in limb injuries is less common.

Biomechanical characterization of cadaveric brachial plexus microstructure.

Introduction: Peripheral nerves consist of axons and connective tissue. The amount of connective tissue in peripheral nerves such as the brachial plexus varies proximally to distally. The proximal regions of the brachial plexus are more susceptible to stretch injuries than the distal regions.

Biomechanical characterization of cadaveric brachial plexus regions using uniaxial tensile tests.

Introduction: The proximal regions of the brachial plexus (roots, trunks) are more susceptible to permanent damage due to stretch injuries than the distal regions (cords, terminal branches). A better description of brachial plexus mechanical behavior is necessary to better understand deformation mechanisms in stretch injury. The purpose of this study was to model the biomechanical behavior of each portion of the brachial plexus (roots, trunks, cords, peripheral nerves) in a cadaveric model and report differences in elastic modulus, maximum stress and maximum strain.

Outcomes of Arthrodesis of the Metacarpophalangeal Joint of the Thumb for Sequelae of Collateral Ligament Injuries: A Series of 18 Cases with 6-Year Follow-Up.

Untreated or insufficiently treated collateral ligament injuries of the thumb metacarpophalangeal (MP) joint can lead to instability or even osteoarthritis. Arthrodesis is one of the treatment options available for the treatment of the sequelae of collateral ligament injuries. The objective of our study was to evaluate the radiological, clinical and functional outcomes of MP joint arthrodesis performed for sequelae of collateral ligament injuries.

Cadaveric study of flexor digitorum profundus and superficialis and flexor pollicis longus innervation patterns for application in selective neurectomy.

Purpose: Spasticity management in finger flexors (flexor digitorum profundus and superficialis and flexor pollicis longus) is a challenge. Recent studies demonstrated the short- and long-term efficacy of selective and hyperselective neurectomy for the spastic upper limb. However, hyperselective neurectomy of flexor digitorum profundus and flexor digitorum superficialis branches was incomplete, without impairing their muscular body and function.

Comparison of proximal row carpectomy with RCPI® versus proximal row carpectomy with Eaton's capsular interposition in the management of advanced wrist osteoarthritis.

Introduction: Proximal row carpectomy (PRC) is one of the recommended techniques for managing wrist osteoarthritis, it implies the integrity of the lunate fossa of the radius and the proximal pole of the capitate. If PRC is not possible, it is suggested to consider combining it with a capsule interposition (such as Eaton's flap) or opting for intra- or radiocarpal arthrodesis. Another alternative is to combine capitate resurfacing with a pyrocarbon implant (RCPi®).

Ligamentoplasty in scapholunate instability: short-term results of the "all dorsal scapholunate repair" technique.

Injury to the scapholunate complex is the cause of scapholunate instability which can lead to radiocarpal and medio-carpal osteoarthritis. Several ligamentoplasty techniques have been reported for the treatment of chronic scapholunate instability before the osteoarthritis stage. The objective of this study was to assess the short-term results of an "all dorsal scapholunate repair" ligamentoplasty.

Radial nerve lesion after medial epicondyle osteosynthesis in a pediatric patient: A rare complication of surgery.

Fractures of the medial epicondyle are relatively common in children and may be associated with nerve lesion, especially in case of displacement. Incarceration of the ulnar nerve in the fracture site is feared in Watson-Jones stage II, rarely directly related to osteosynthesis. Depending on the degree of fracture displacement, various osteosynthesis techniques may be used; nerve injuries are a rare but known complication of these procedures.

Recent and chronic sprains of the First Metacarpo-Phalangeal Joint.

Sprains of the first metacarpo-phalangeal joint (MCPJ) are a common form of hand injury that mainly affects the ulnar collateral ligament. Although the diagnosis is made on the physical findings, radiographs must be obtained and ultrasonography or magnetic resonance imaging (MRI) is necessary in some cases. If the joint is unstable or a bony fragment is displaced, surgery must be performed within 4 weeks after the injury.

Lower-limb Flip-Flap: A simple reliable modification of adipofascial flap for extensive tibial crest cutaneous defect.

Introduction: Large cutaneous defects exposing the whole tibial crest are difficult to cover and are conventionally best treated with free flaps. This article describes a technical modification of the adipofascial flap in this indication.

Methods: The "flip-flap" is vascularized by the posterior tibial artery perforators harvested on the medial aspect of the leg.

Non-healing ischaemic digital ulcer in a systemic sclerosis patient: a challenging clinical case.

Ischaemic digital ulcers (DUs) are an indicator of the severity of the microangiopathy in patients with systemic sclerosis (SSc). DUs are a frequent complication, affecting about 50% of patients with SSc, and are often recurrent. In cross-sectional studies involving patients with SSc, the frequency of ischaemic DUs was 12-16% with a major impact on hand function and quality of life.

Perilunate dislocations and transscaphoid perilunate fracture-dislocations: a retrospective study with minimum ten-year follow-up.

Purpose: Perilunate dislocations and transscaphoid perilunate fracture dislocations are associated with a high incidence of posttraumatic arthritis. According to the current literature, at medium-term follow-up, radiological signs of arthritis do not correlate with functional scores. The aim of this study was to evaluate patient hand function and the development of posttraumatic arthritis after perilunate dislocations (11 cases) and transscaphoid perilunate fracture dislocations (7 cases) at a minimum 10 years of follow-up.

Pulley rupture and reconstruction in rock climbers.

Hand-grip techniques in modern rock climbing generate climbing-related injuries, especially at the flexor tendon sheath level. The most frequent injury is A2 pulley rupture. The clinical diagnosis is based on bowstringing of the flexor tendon and confirmed by computed tomograph scan or magnetic resonance imaging.
