Profunda femoris artery pseudoaneurysm after surgery and trauma

Pseudoaneurysms of the profunda femoris artery have been reported following different types of trauma and from orthopedic procedures performed in the proximal femur. Two cases of profunda femoris artery pseudoaneurysm with two rare causes are presented. The first one is a core decompression of femoral head for osteonecrosis and the second one is a proximal femur fracture nailing. Awareness and careful follow-up are the key issues for the early diagnosis

Rupture of the meniscofibular ligament

The meniscofibular ligament is an anatomically defined ligament of the knee in humans. However, there are no data regarding the prognosis following injury to this ligament. Our case was a 42-year-old man who presented at our clinic with pain of the lateral side of his left knee. MRI of his left knee revealed the rupture of the meniscofibular ligament. The mechanism of injury was consistent with anatomical and mechanical studies of the meniscofibular ligament. The patient was treated conservatively for 1 year, but his pain did not resolve completely. A case series of patients with the same injury is required to establish an effective treatment for this rare injury

Open reduction and percutaneous pinning for medial condyle fractures of elbow in children: is it a risk for complications?

Background: There are limited cases of humerus medial condyle fracture in the literature treated by open reduction and percutaneous pinning. This study presents cases treated by open reduction and percutaneous pinning and discussed the problems reported in the literature.Methods: Nine cases were treated by open reduction and percutaneous pinning between 2006-2014. These cases were followed for nonunion, avascular necrosis, range of motion, nerve lesion and infection for 15.3 months (range 11 to 18 months).Results: No non-union, avascular necrosis, iatrogenic nerve lesion or infection developed in our cases. All patients gained full range of motion.Conclusions: This study presents that surgical technique and early timing of surgery prevents the complications

Simultaneous ipsilateral proximal interphalangeal and metacarpophalangeal dislocation of the fifth phalanx: A case report

We propose, analyze and demonstrate the optoelectronic phase-locking of optical waves whose frequencies are chirped continuously and rapidly with time. The optical waves are derived from a common optoelectronic swept-frequency laser based on a semiconductor laser in a negative feedback loop, with a precisely linear frequency chirp of 400 GHz in 2 ms. In contrast to monochromatic waves, a differential delay between two linearly chirped optical waves results in a mutual frequency difference, and an acoustooptic frequency shifter is therefore used to phase-lock the two waves. We demonstrate and characterize homodyne and heterodyne optical phase-locked loops with rapidly chirped waves, and show the ability to precisely control the phase of the chirped optical waveform using a digital electronic oscillator. A loop bandwidth of ∼ 60 kHz, and a residual phase error variance of < 0.01 rad^2 between the chirped waves is obtained. Further, we demonstrate the simultaneous phase-locking of two optical paths to a common master waveform, and the ability to electronically control the resultant two-element optical phased array. The results of this work enable coherent power combining of high-power fiber amplifiers—where a rapidly chirping seed laser reduces stimulated Brillouin scattering—and electronic beam steering of chirped optical waves

A clay-shoveler's fracture with renal transplantation and osteoporosis: a case report

<p>Abstract</p> <p>Introduction</p> <p>Clay-shoveler's fracture is a rare cervicodorsal spinous process fracture and there is little information regarding the prognosis of patients with this condition in conjunction with osteoporosis and corticosteroid use.</p> <p>Case presentation</p> <p>A 39-year-old man was admitted to our institution with a 6-month history of cervicodorsal pain prior to admission. The patient had previously undergone renal transplantation and was on corticosteroids, and had developed osteoporosis. We treated him with a cervical collar, non-steroidal anti-inflammatory agents and alendronate. The patient was advised against performing weight-bearing activities for 6 months.</p> <p>Conclusion</p> <p>Clay-shoveler's fracture with osteoporosis and corticosteroid use presented by fracture of the cervicodorsal aspect of the spinous processes may be successfully treated with a collar, alendronate and long-term rest.</p

Pyomyositis of tensor fascia lata: a case report

<p>Abstract</p> <p>Introduction</p> <p>Pyomyositis is a disease in which an abscess is formed deep within large striated muscles.</p> <p>Case presentation</p> <p>We report the case of a 10-year-old boy who presented with fever and a painful hip and was subsequently diagnosed with pyomyositis of the tensor fascia lata. In children with clinical and laboratory findings of inflammation in the vicinity of the hip joint, the differential diagnosis includes transient synovitis, an early stage of Legg-Calvé-Perthes disease, infectious arthritis of the hip, rheumatologic diseases and extracapsular infection such as osteomyelitis.</p> <p>Conclusion</p> <p>To the best of the authors' knowledge, this is the first report of pyomyositis of the tensor fascia lata. Although pyomyositis is a rare disease and the differential diagnosis includes a variety of other commonly observed diseases, pyomyositis should be considered in cases where children present with fever, leukocytosis and localized pain.</p
