Abstract:

Ruptures of the scapholunate ligament (SLL) may cause carpal instability, also known as scapholunate dissociation (SLD). SLD may lead to osteoarthritis of the radiocarpal and midcarpal joints. The aim of this retrospective study was to determine the diagnostic value of wrist cineradiography in detecting SLD. All cineradiographic studies made during a 24 year period were retrieved. All patients who underwent the confirmation method (arthroscopy and/or arthrotomy) and cineradiography were included. In total, 84 patients met the inclusion criteria. Sensitivity, specificity, likelihood ratio, positive predictive value, negative predictive value, and diagnostic accuracy for detecting SLD were calculated for radiography and cineradiography. Cineradiography had a sensitivity of 90%, a specificity of 97%, and a diagnostic accuracy of 0.93 in detecting SLD. Radiography had a sensitivity of 81%, a specificity of 80%, and a diagnostic accuracy of 0.81. Cineradiography has a high diagnostic value for diagnosing SLDs. A positive cineradiography markedly increases the post-test probability of SLD.

Abstract:

Carpal instability is often related to ruptured or lax carpal ligaments. Wrist cineradiography has been shown to be a good modality for diagnosing carpal instability. To create uniformity in obtaining and assessing wrist cineradiography, a wrist cineradiography protocol is desirable. This protocol will focus on wrist cineradiography for diagnosing carpal instabilities. It describes the pathologic motions of the carpus and correlates these with a clinical diagnosis.

Abstract:

Cineradiographic examination of the pharynx is a valuable tool for evaluation of patients with swallowing complaints. The direct functional imaging is the essence of cineradiography of the pharynx during swallowing. In this way the motor function of the pharynx can be monitored. The kind and number of specific dysfunction can give a valuable information about the severity of pharyngeal impairment. Using a scoring system compensation and decompensation of pharyngeal function can be assessed, thereby offering an understanding of the patients' swallowing ability.

Abstract:

This study investigated the extent to which high-speed lateral-view cineradiography and a photodetector system described by Dalston (1982) provided comparable information concerning velopharyngeal activity. We observed the production of isolated utterances and running speech for 2 subjects in three contexts. A comparison was made between the times at which the velopharyngeal port was observed by each method to begin opening, reach maximal opening, begin closing, and initially attain closure. The photodetector system was found to be sensitive to changes in velar position observed by cineradiography. The correlation between the magnitude of photodetector output and the magnitude of velar displacement from the posterior pharyngeal wall was .89 for Subject 1 and .78 for Subject 2. The lack of a perfect relation between the output of the photodetector device and movements of the velum observed by cineradiography was not unexpected given the two-dimensional limitation of lateral cineradiography and the complexity of events associated with changing port size. The significance of these findings is discussed with respect to the potential research and clinical uses of this photodetector system.

Abstract:

X-ray and cineradiography measurements were used to compare the suspension effect and stability of a TSB trans-tibial prosthesis with an Icelandic Roll-On Silicone Socket (ICEROSS) system to that of a PTB trans-tibial prosthesis. The suspension effect was measured by the distance between the tibia and the socket in both suspension position and weight-bearing position in both type of prostheses. The suspension effect of the TSB prosthesis (2.53 ± 0.90cm) was superior to that of the PTB prosthesis (3.60 ± 0.56cm) (p<0.05) by x-ray measurement. The suspension effect of the TSB prosthesis (0.1, 0.4, 0.72cm) was superior to that of the PTB prosthesis (0.3, 0.48, 1.03cm) (p<0.01, p<0.05) by cineradiographic measurement. The stability was measured as the angle between the axis of the tibia and the prosthesis at the time of heel contact and toe off. The angle change of the TSB prosthesis was statistically smaller than that of the PTB prosthesis.

Abstract:

The pattern of swallowing by which the oral bolus reaches an air-containing oropharynx is called an ‘open swallow’ whereas the sequence in which the oropharynx is collapsed on the arrival of the bolus is called a ‘closed swallow’. The significance of this distinction was further analyzed by a correlation with other laryngeal and pharyngeal functions during swallowing in a cineradiologic study in 75 dysphagic patients and 50 asymptomatic volunteers. The relative incidence of open and closed type swallows was similar in the two groups. The maximum elevation of the pharynx and larynx was the same in open and closed swallow, although in individuals with an open swallow the elevation occurred later than in individuals with a closed swallow. Epiglottic movement disturbances, defective closure of the laryngeal vestibule, pharyngeal constrictor muscle paresis, cricopharyngeal incoordination, cervical esophageal webs and Zenker diverticula were significantly more common in individuals with an open pharyngeal swallow than in those with closed swallowing.

Abstract:

The use of tracheoesophageal voice prostheses has gained wide acceptance in the field of vocal rehabilitation after total laryngectomy. In a randomized study with 3 arms, alaryngeal speech proficiency was assessed in 60 postlaryngectomy patients: 20 patients underwent primary unilateral pharyngeal myotomy, 21 patients underwent neurectomy of the pharyngeal plexus in addition to pharyngeal myotomy, and 19 patients did not undergo an additional surgical procedure. Pharyngoesophageal (PE) dynamics were examined during esophageal and tracheoesophageal speech. A single vibrating PE segment was seen in good alaryngeal speakers. Hypertonicity, spasm, strictures, and hypotonicity of the PE segment were correlated significantly with poor or moderate alaryngeal speech. Unilateral myotomy with or without unilateral neurectomy prevented hypertonicity or spasm of the PE segment. The acquisition of alaryngeal speech did not differ significantly between the 2 groups who had undergone an additional surgical procedure. Evaluation of anatomic and physiological factors may be helpful in subsequent clinical management to achieve effective alaryngeal speech.

Abstract:

The kinematics of intraoral transport and swallowing in lizards of the species Uromastix acanthinurus (Chamaeleonidae, Leiolepidinae) were investigated using cineradiography (50 frames s-1). Additional recordings were also made using high-speed (500 frames s-1) and conventional video systems (25 frames s-1). Small metal markers were inserted into different parts of the upper and lower jaw and the tongue. Cineradiographic images were digitised, and displacements of the body, head, upper and lower jaw and the tongue were quantified. Twenty additional variables depicting displacements and the timing of events were calculated. Multivariate analyses of variance indicated significant differences between feeding stages. Remarkably, only very few food-type-dependent differences were observed during intraoral transport, and no such differences could be demonstrated during swallowing. Using previously published data for the closely related insectivorous lizard Plocederma stellio, the effect of dietary specialisation in U. acanthinurus on the kinematic variables while eating locusts was examined. Species differed in a number of gape- and tongue-related variables. These differences may be related to differences in tongue structure between the species. Clearly, U. acanthinurus possesses a specialised gut and dental structure that allows them efficiently to cut pieces from whole leaves. However, a decrease in modulatory capacity seems to be a consequence of dietary specialisation in Uromastix acanthinurus.

Abstract:

The kinematics of prey capture, reduction and transport to the oesophagus by the iguanian lizard Oplurus cuvieri were investigated using high-speed cinematography (100–200 frames s−1) and cineradiography (60 frames s−1). Thirty feeding sequences from four individuals were analysed. Feeding sequences were divided into four phases: capture, reduction, transport to the oesophagus and cleaning. Quantified kinematic profiles of the head, jaws, hyoid-tongue complex and displacements of the prey to (capture) and within (other phases) the buccal cavity are presented from cinematographic frames. Twenty additional variables, depicting maximal displacements and the timing of events, were calculated from the profiles. Variables documenting gape cycles were used in a first principal component analysis for studying the kinematic relationships between the phases. Markers were placed in the tongue of two individuals for cineradiographic study to illustrate displacements of the tongue. During prey capture, the jaw cycle is divided into slow opening (SO I and SO II), fast opening (FO) and fast closing (FC) stages. During the reduction phase, jaw cycles do not always involve an SO stage and the first reduction cycle never exhibits an SO stage. During transport, the duration of the SO stages is highly variable. During reduction and transport of the prey, the cyclic tongue movements are very similar. Gape opening during cleaning is not divided into two successive stages. We conclude (1) that the capture, reduction and cleaning cycles may be derived from the transport cycle, (2) that the SO stage is determined by tongue displacements in all the phases, (3) that, in the extensive intraoral food processing, related cyclic tongue-jaw displacements are not different, (4) that gape cycles do not always follow the Bramble and Wake model, and (5) that the evolutionary features proposed for Amniota by Reilly and Lauder are present.

Abstract:

The kinematics of prey capture, intraoral transport and swallowing in lizards of the species Agama stellio (Agamidae) were investigated using cineradiography (50 frames s-1) and high-speed video recordings (500 frames s-1). Small metal markers were inserted into different parts of the upper and lower jaw and the tongue. Video and cineradiographic images were digitized, and displacements of the body, head, upper and lower jaw and the tongue were quantified. Twenty additional variables depicting displacements and timing of events were calculated. A factor analysis performed on the kinematic data separates prey capture and swallowing cycles from intraoral transport bites. However, the intraoral transport stage cannot be separated into chewing (reduction) and transport bites. The effect of prey type and size on the feeding kinematics of intraoral transport and swallowing cycles was investigated. During the intraoral transport stage, distinct aspects (e.g. durations, maximal excursions) of the gape and tongue cycle are modulated in response to both the size and type of the prey item. The results for A. stellio generally agree with a previous model, although it is the entire slow opening phase rather than solely the duration of the second part of this phase that is affected by the size of the prey. The intraoral transport cycles in A. stellio show the two synapomorphic characteristics of tetrapods (tongue-based terrestrial intraoral prey transport and the existence of a long preparatory period of prey compression). However, not all five characters of the feeding cycle previously proposed for amniotes are present in A. stellio. One major difference is that in A. stellio the recovery of the hyolingual apparatus does not take place during the slow opening phase but during the slow closing/powerstroke phase.

Abstract:

We have reviewed prospectively 44 cases of chronic scapholunate dissociation treated by Blatt’s dorsal capsulodesis. The diagnosis was based on clinical and arthroscopic criteria. The minimum follow-up was 2 years. The results were analysed clinically and radiologically. Postoperatively statistically significant reductions in wrist movements and grip strengths were noted. Delay in surgery and presence of compensation claims were also statistically significant factors. Patients with a high column/row index had higher overall good and excellent results. The scapholunate gap, scapholunate angle, carpal height and the type of instability as diagnosed on arthroscopy and cineradiography did not affect the outcome significantly. The scapholunate gap, scapholunate angle and the carpal height did not change significantly after operation.

Abstract:

The localization of the upper esophageal sphincter is partly controversial. The aim of the present study was to elucidate whether or not the sphincter area could be allocated within an area inferior to and separate from the cricopharyngeal muscle. Cineradiography of the pharyngo-esophageal segment in 252 dysphagial patients disclosed a posterior impression in 55 (22%). There were no signs of a circular impression or other indications of a sphincter localized inferior to the circopharyngeus as revealed on these cinefilms. Macro- and microscopic examination of 16 autopsy specimens revealed the level of the upper esophageal sphincter to be localized within the cricopharyngeal muscle. There was no indication of any sphincter inferior to the crico-pharyngeus in the cervical esophagus.

Abstract:

In a cineradiographic analysis of the vomiting reflex in response to i.v. administration of an emetic drag (lanatoside C, 12 mg/kg) in cats, it was shown that the vomiting act is preceded by cyclic periods of abnormal peristaltic activity of the small bowel and inhibition of gastric peristalsis. It was further observed that massive antiperistalsis of the upper small bowel with reflux into the stomach is a common occurrence in the period immediately preceding vomiting. The emetic act itself is composed of phases of esophageal dilation, gastric emptying, gastric reflux, and esophageal collapse in cyclic repetition. The response of the esophagus and the stomach during emesis is passive, with external pressures and forces apparently providing the expulsive forces, the gastric bolus being contained by contraction of the pylorus and probably an upper esophageal or pharyngeal barrier. Earlier studies were conducted in cats in which observations were made on changes in thoracic venous pressure, abdominal venous pressure, and arterial blood pressure associated with vomiting induced by Veratrum alkaloids. Retching was characterized by a growing series of brief negative inthrathoracic pressure pulses mirrored by positive pressure pulses in the abdomen. Expulsion then occurred and was followed with a sudden reversal of intrathoracic pressure from negative to positive. Expulsion involved a more sustained abdominal contraction, but both retching and expulsion were brought about by the same set of muscles, according to their EMG profiles. From results observed following phrenicotomy and spinal cord section at T5, it was concluded that the diaphragm, acting together with the inspiratory muscles against a closed glottis, is responsible for the negative intrathoracic pressure that occurs in retching. It was also concluded that the abdominal musculature is responsible for the positive pressure generated in the abdomen during retching and expulsion, and which in the latter phase is transmitted into the thorax by an upward shift of the diaphragm.Key words: emesis, cineradiography, peristalsis, motility, tachyarrythmia.

Abstract:

Iguanian lizards generally use their tongue to capture prey. Because lingual prehension is based on surface phenomena (wet adhesion, interlocking), the maximal prey size that can be captured is small. However, published records show that prey items eaten by chameleons include small vertebrates such as lizards and birds, indicating that these lizards are using a different prey prehension mechanism. Using high-speed video recordings, cineradiography, electromyography, nerve transection and stimulation experiments, we investigated the function of the tongue during prey capture. The results of these experiments indicate that chameleons have modified the primitive iguanian system by including a suction component in their prehension mechanism. Suction is generated by the activity of two modified intrinsic tongue muscles that pull the tongue pad inwards. Moreover, we demonstrate that the mechanism described here is a prerequisite for successful feeding.

Abstract:

The purpose of the present study was to investigate whether or not sensory input from the tongue affects deglutitive tongue movement. Subjects were seven healthy volunteers with anesthetic applied to the surface of the tongue (surface group) and seven healthy volunteers with the lingual nerve blocked by anesthetic (blocked group). We established six stages in deglutition and analyzed deglutitive tongue movement and the time between the respective stages by cineradiography before and after anesthesia. After anesthesia in both surface and blocked groups, deglutitive tongue movement slowed and bolus movement was delayed. The deglutitive tongue tip retreated in the blocked group. These results suggest that delay of tongue movement by anesthesia causes weak bolus propulsion and that deglutitive tongue tip position is affected by sensory deprivation of the tongue or the region innervated by the inferior alveolar nerve.

Abstract:

The oral stage of swallowing was radiologically evaluated in 19 patients with swallowing complaints. Eight patients had had surgical resection and reconstruction due to tumours of the tongue, floor of the mouth or mandible. Eleven patients had suffered from cerebrovascular disease. All patients had incoordination of tongue movements including defective initiation of pharyngeal swallow. In patients who had undergone surgical resection, oral dysfunction correlated with the extension of resection as well as type of reconstruction, and was more profound compared with the disorder present in patients with cerebrovascular disease. Moreover, muscular derangement due to surgery of the floor of the mouth interfered with the elevation of the hyoid bone, larynx and pharynx and thereby the pharyngeal stage of swallowing also became abnormal. Cineradiography seems to be an appropriate method for evaluation of the oral stage of swallowing in patients with deglutition complaints.

Abstract:

Robots are increasingly used as scientific tools to investigate animal locomotion. However, designing a robot that properly emulates the kinematic and dynamic properties of an animal is difficult because of the complexity of musculoskeletal systems and the limitations of current robotics technology. Here, we propose a design process that combines high-speed cineradiography, optimization, dynamic scaling, three-dimensional printing, high-end servomotors and a tailored dry-suit to construct Pleurobot: a salamander-like robot that closely mimics its biological counterpart, Pleurodeles waltl . Our previous robots helped us test and confirm hypotheses on the interaction between the locomotor neuronal networks of the limbs and the spine to generate basic swimming and walking gaits. With Pleurobot, we demonstrate a design process that will enable studies of richer motor skills in salamanders. In particular, we are interested in how these richer motor skills can be obtained by extending our spinal cord models with the addition of more descending pathways and more detailed limb central pattern generator networks. Pleurobot is a dynamically scaled amphibious salamander robot with a large number of actuated degrees of freedom (DOFs: 27 in total). Because of our design process, the robot can capture most of the animal's DOFs and range of motion, especially at the limbs. We demonstrate the robot's abilities by imposing raw kinematic data, extracted from X-ray videos, to the robot's joints for basic locomotor behaviours in water and on land. The robot closely matches the behaviour of the animal in terms of relative forward speeds and lateral displacements. Ground reaction forces during walking also resemble those of the animal. Based on our results, we anticipate that future studies on richer motor skills in salamanders will highly benefit from Pleurobot's design.

Abstract:

Between 1995 and 2000, 8 patients with St. Jude Medical (SJM) valves in the aortic position required 9 redo valve replacement for prosthetic valve obstruction. Obstruction of the prosthetic valve was diagnosed by simultaneous echocardiography and cineradiography, and process of restricted leaflet movement that progressed to hemodynamic impairment was observed by serial studies in three recent patients. An oral anticoagulation was considered to be adequate in all patients except one patient who had withdrawal of warfrain. Pannus was the sole cause of valve obstruction in seven events in 6 patients, and both thrombus and pannus in 2 patients. Pannus overgrowth was found on the inflow aspect of the SJM valve, and involved the ends of the straight edge of the leaflets over pivot guards. These results suggest that pannus might play the primary role in development of obstruction of aortic SJM valves in patients on adequate oral anticoagulation.

Abstract:

AbstractBeyond clinical examination, the various forms of carpal instability are assessed with radiologic methods and arthroscopy. For this purpose, the imaging demand for spatial and contrast resolution is particularly high because of the small ligamentous structures involved. The entities of carpal instability are classified into degrees of severity. Early (dynamic) forms of instability can either be indirectly detected with X-ray stress views and cineradiography or by direct visualization of ruptured ligaments in high-resolution magnetic resonance (MR) imaging and MR or computed tomography (CT) arthrography, with the latter the standard of reference in imaging. Advanced (static) forms of carpal instability are sufficiently well detected on radiographs; visualization of early carpal osteoarthritis is superior on CT. To prevent disability of the hand, the radiologist has to provide an early and precise diagnosis. This case-based review highlights the imaging procedures suitable for detection and classification of carpal instability.

Abstract:

This prospective study investigated static scapholunate dissociation (SLD) in wrists associated with distal radius fractures. SLD was detected as a widening of the scapholunate (SL) joint interval by SL gap view. Ninety-six distal radius fractures and 154 normal wrists were investigated by SL gap view, which is better for detecting SLD than the standard posteroanterior (PA) view. Incidences of non-symptomatic SLD detected by SL gap view in normal wrists increased by age. In the young age bracket, incidences of SLD in distal radius fractures were significantly higher than in normal wrists. Our results indicated that in patients younger than 30 years old, SLD in distal radius fractures was a fracture-caused abnormality. In those over 30, ascribing SLD to the fracture was difficult. Close examinations, like arthroscopy and dynamic cineradiography, need to be made in patients with SLD associated with distal radius fractures, especially in those younger than 30.
