Only few electron microscopic studies exist on the structure of the main eyes (anterior median eyes, AME) of web spiders. The present paper provides details on the anatomy of the AME in the funnel-web spider Agelena labyrinthica. The retina consists of two separate regions with differently arranged photoreceptor cells. Its central part has sensory cells with rhabdomeres on 2, 3, or 4 sides, whereas those of the ventral retina have only two rhabdomeres on opposite sides. In addition, the rhabdomeres of the ventral retina are arranged in a specific way: Whereas in the most ventral part they form long tangential rows, those towards the center are detached and are arranged radially...

The aim of this study is to evaluate the complications of humeral lengthening and their associated factors. Fifty-four achondroplastic patients were treated by bilateral humeral lengthening. Our original shoulder sling was sufficient to prevent shoulder dislocation. Pre-existing radial head dislocation was observed in 18 patients. Lengthening was accomplished in all cases without a decrease in the elbow function. Seven humeri fractured after the fixator removal. The risk factors for postoperative fracture were a waiting period of less than 5 days, a healing index less than 25, and the concave shape of the callus...

BACKGROUND: The ulnar coronoid process plays a central role in maintaining elbow stability. Some of its fractures were often combined with injury of bone and ligament. Arthroscopy enables perfect visualization to allow anatomical repair. METHODS: From January 2012 to December 2013, six patients (four males, two females) with a mean age of 26.6 years were treated. The left and right ulnas were involved in two and four patients, respectively. All patients suffered from ipsilateral subluxation of the elbow without associated radial fracture...

Neuropathic symptoms after median nerve repair at the wrist or secondary to refractory carpal tunnel syndrome may become debilitating. These symptoms develop due to perineural adhesions, intraneural fibrosis and fixation of the nerve to the transverse carpal ligament after surgery and often require neurolysis. Interposition of vascularized soft tissue over the median nerve at the time of neurolysis prevents recurrence of such adhesions. The synovial flap, fashioned from the synovial lining of the flexor tendon sheath, is an ideal tissue for this purpose...

Carpal tunnel syndrome, the most common entrapment neuropathy of the upper extremity, is caused by compression of the median nerve as it travels through the carpal tunnel. Classically, patients with the condition experience pain and paresthesias in the distribution of the median nerve, which includes the palmar aspect of the thumb, index and middle fingers, and radial half of the ring finger. Additional clues include positive physical examination findings, such as the flick sign, Phalen maneuver, and median nerve compression test...

BACKGROUND: Manipulating the carpal arch width (i.e. distance between hamate and trapezium bones) has been suggested as a means to increase carpal tunnel cross-sectional area and alleviate median nerve compression. The purpose of this study was to develop a finite element model of the carpal tunnel and to determine an optimal force direction to maximize area. METHODS: A planar geometric model of carpal bones at hamate level was reconstructed from MRI with inter-carpal joint spaces filled with a linear elastic surrogate tissue...

: Pediatric radial neck fractures are uncommon. Severely displaced and angulated fractures usually require treatment. Our goals for treatment are to avoid incision, reduce the fracture adequately with no reduction loss, and achieve good postoperative function. We aimed to observe the clinical outcomes of closed reduction with the percutaneous leverage technique and internal fixation with Kirschner-wires (K-wires) to treat angulated radial neck fractures in children.From January 2011 to April 2013, we treated 16 cases of angulated radial neck fracture in 12 boys and 4 girls...

BACKGROUND: Radial nerve injury is common in humeral shaft fractures and fails to recover spontaneously in 30% of cases. Few studies have evaluated predictors of recovery.The objectives of this study were to identify predictors of radial nerve palsy recovery and to assess the usefulness of surgical radial nerve exploration in patients with pre-operative radial nerve palsy. HYPOTHESIS: Factors predicting the outcome of radial nerve palsy can be identified. METHODS: Of 373 patients with humeral shaft fractures between 2005 and 2012, 43 had radial nerve palsy, including 23 who were lost to follow-up and 17 who were evaluated retrospectively at a mean of 26 months (range, 12-84 months) after internal fixation...

INTRODUCTION: Distal radius fracture are common injuries but no gold standard for their therapy exists. The aim of this study was to evaluate the quality of fracture care in distal radius fractures using an intramedullary implant (Targon DR interlocking nail). The nail had been developed to minimize the surgical exposure, increase fixation strength, to prevent tendon irritations and to allow for a fast return to activity. PATIENTS AND METHODS: Prospective study reports the result of 43 patients with an age over 70 years (range 70-91 years) treated by closed reduction and intramedullary fixation...

BACKGROUND: Astrocytes migrate into the retina through the optic nerve head via the axons of retinal ganglion cells, and spread radially towards the peripheral retina. Endothelial cells migrate along the astrocyte cellular network to form the retinal surface vasculature. Here, we examined the effects of a delay in retinal vascularization on the migration and proliferation status of astrocytes in mice. RESULTS: A dose-dependent delay in retinal vascularization was observed in mice that had been treated with KRN633 (1-10 mg/kg), a VEGF receptor inhibitor, on the day of birth and on the following day...
