Posterior interosseous nerve to the superficial branch of the ulnar nerve transfer at the distal third of the forearm through a single anterior approach: Anatomical feasibility study.

The purpose of this study was to determine in a cadaver model, whether transfer of the posterior interosseous nerve (PIN) to the superficial branch of the ulnar nerve (SBUN) by a single approach was feasible. The experiment was carried out on five fresh cadavers. The ulnar nerve was split into its motor branches and the SBUN.

Long Volar Plating for Metadiaphyseal Fractures of Distal Radius: Study Comparing Minimally Invasive Plate Osteosynthesis versus Conventional Approach.

 Minimally invasive plate osteosynthesis (MIPO) has been used in wrist surgery for several years. The purpose of this retrospective study was to compare clinical and radiologic outcomes of MIPO technique with those of a conventional approach in the treatment of metadiaphyseal distal radius fracture by long volar plating.  Our series consisted of 32 fractures in 31 patients, mean age 63.

Design and evaluation of a new synthetic wrist procedural simulator (Wristsim) for training of distal radius fracture fixation by volar plating.

Legislation concerning workload of surgical trainees and pressure to reduce learning curves have forced us reconsider surgical training. Our goal was to evaluate a synthetic procedural simulator for teaching open reduction and internal fixation (ORIF) of distal radius fractures (DRF). Twenty surgeons used a synthetic procedural simulator (Wristsim) made by 3D printing for ORIF of DRF with a volar plate (Newclip Technics).

Rotational stability test for the diagnosis of radial collateral ligament rupture in the fingers: Anatomical study.

Diagnosing rupture of the radial collateral ligament (RCL) of the finger metacarpophalangeal (MCP) joints is difficult. The aim of this cadaver study was to validate a rotational test for the MCP after RCL transection. With the MCP and proximal interphalangeal joints in flexion, rotation along the axis of the proximal phalanx was applied through an extended distal interphalangeal joint to 36 cadaver fingers.

Treatment of acute perilunate dislocations: ORIF versus proximal row carpectomy.

Purpose: Some authors have proposed performing proximal row carpectomy (PRC) as the initial treatment for perilunate dislocations.

Hypothesis: The goal of this retrospective study was to compare the results of a cohort of perilunate dislocation cases that were operated by open reduction and internal fixation (ORIF) or by PRC between 2006 and 2011.

Methods: The cohort consisted of 21 men with a mean age of 33years, who either had an isolated perilunate dislocation (7 cases) or a fracture-dislocation (14 cases).

Resistance of primary microsurgical repair of palmar digital nerves to finger mobilization: A cadaver study.

The aim of this study was to assess the resistance of microsurgically repaired proper palmar digital nerves (PPDN) to mobilization. Thirty-nine PPDN from fresh forearms cadavers were transected and then sutured using 10/0 nylon. After skin closure, each finger was forcefully flexed and extended 10 times.

Proximodistal interphalangeal arthrodesis of the little finger: A series of 7 cases.

As an alternative to amputation of the little finger, we report here seven cases of shortening arthrodesis carried out by resecting the middle phalanx and proximodistal interphalangeal (PDIP) arthrodesis. Our cohort consisted of 6 males and 1 female (58years average age), with a stiff little finger secondary to Dupuytren's disease or trauma. All fingers were approached dorsally; after resection of the middle phalanx and decortication of the subchondral bone, fusion of the remaining phalanges was performed using an intramedullary self-breaking screw-pin.

Consequences of pneumoperitoneum on liver ischemia during laparoscopic portal triad clamping in a swine model.

Background: Portal triad clamping (PTC) may be required during laparoscopic liver resection to limit blood loss. The aim of this study was to test in a swine model the hypothesis that during laparoscopic PTC, increased intraperitoneal pressure may alter hepatic vein reverse circulation, inducing a more severe hepatic ischemia compared with PTC performed in laparotomy.

Methods: Fifteen pigs were randomized into three groups: laparoscopy (1 h of pneumoperitoneum at 15 mmHg and 3 h of surveillance), open PTC (1 h PTC through laparotomy and 3 h of reperfusion), and laparoscopic PTC (1 h PTC with 15 mmHg pneumoperitoneum and 3 h of reperfusion).

[Dream in the land of paradoxical sleep].

Paradoxical sleep (PS or REM sleep) is traditionally a matter for neurophysiology, a science of the brain. Dream is associated with neuropsychology and sciences of the mind. The relationships between sleep and dream are better understood in the light of new methodologies in both domains, particularly those of basic neurosciences which elucidate the mechanisms underlying SP and functional imaging techniques.
