Anatomical variations in the first extensor compartment of the wrist. A clinical and anatomical study.

Objective: The objective of this study is to comprehensively put forth the anatomical variations in the origin and course of lingual and facial arteries found in adult cadavers. Methods: Ten human cadavers were dissected and studied for variations from the norm regarding facial and lingual arteries . Results: 80% of the cadavers displayed classical origin and course of the arteries. There was a deviation from normal regarding origin of the arteries in 20% of the cadavers. Meanwhile, abnormality in the course amounted to 10%. Conclusion: In 20% of cadavers, there were variations in origin of facial and lingual arteries , meanwhile, changes in the course of the stated arteries is 10%. These variations prove to be of signicance to surgeons to prevent mishaps and hospital acquired infections, while performing carotid endarterectomy, intra-arterial catheterizations, plastic surgery of the face and resection of malignant tumours.

ABSTRACT In the present study Scilla luciliae, S. forbesii, S. sardensis, S. siehei, Scilla x allenii and S. bifolia are compared anatomically. Some differences have been found in root, scape, and leaf anatomy of the taxa, and commented. S. luciliae, S. forbesii, S. sardensis and S. siehei have a metaxylem at the center of the root, others have 3-4 number metaxylem. Vascular bundles in two row in S. luciliae and S. forbesii in a single row in S. sardensis, Scilla x allenii and S. bifolia though in three rows in S. siehei. Aerenchyma tissue is present in mesophyll of five taxa leaf except S. sardensis. The anatomical variations in the taxa have been investigated by means of numerical methods (Analysis of variance and Pearson correlation). By the analysis of the investigated taxa from 12 anatomy related characters, it has been also found that the results from numerical analysis of anatomy characters can provide additional evidences, which correspond to the anatomy for the recognition of the taxa.

PURPOSE: Despite the fact that anatomical variations of the celiac trunk are well explored in the literature, information on these vessels diameters is scanty. The aims of the present study were to describe the arterial diameters of the celiac trunk and its main branches, and to investigate if these diameters are altered in those cases presenting anatomical variations of these vessels. METHODS: Twenty-one formalin fixed adult male cadavers were appropriately dissected for the celiac trunk identification and arterial diameter measurements. Arteries measured included the celiac trunk and its main branches (splenic artery, left gastric artery and common hepatic artery), as the proper hepatic artery, right gastric artery, the left and right hepatic arteries and the gastroduodenal artery. RESULTS: From the 21 cadavers, 6 presented anatomical variations of, at least, one of the above mentioned branches. The average arterial diameter comparisons between groups (normal and variable) clearly showed smaller diameters for variable vessels, but with no significant difference. CONCLUSION: Our data indicates the possibility of a diameter reduction of the celiac trunk main branches in the presence of anatomical variations. This should be taken into account on the selection for the liver transplantation donors.

The basic anatomy of the first extensor compartment is presented with a review of the pathology of de Quervain’s stenosing tenovaginitis. The results in 100 medicolegal cases of de Quervain’s disease are analysed and reasons are sought for the poor results. A review of the known factors associated with the causation of de Quervain’s disease is presented with recommendations about the management of this condition.

Extensor Compartment

AbstractPersistent pain despite previous surgery for de Quervain’s disease might be due to an overlooked septum between the abductor pollicis longus tendon slips and the extensor pollicis brevis tendon, or an overlooked completely separate compartment for the extensor pollicis brevis tendon alone. In both of these instances, extension of the MP joint of the thumb against resistance elicits pain at the distal level of the first extensor compartment of the wrist. When this sign is positive, revisional surgery and decompression of the remaining septum or separate compartment is indicated.

Background: The Extensor Pollicis Brevis (EPB) is an extrinsic thumb muscle whose main function is extension of the first metacarpophalangeal joint (MCPJ). It is subject to significant anatomical variation and may be absent, vestigial or have an anomalous distal attachment. Clinical examination of EPB is notoriously difficult and no reliable test has yet been described. We propose a novel test for the accurate examination of EPB. We sought to clarify the anatomical variations of EPB and to validate our clinical test using human cadaveric anatomical tests. Methods: A structured literature review of all human cadaveric anatomical studies describing the attachments of EPB was performed using MEDLINE and Embase with the key words “Extensor Pollicis Brevis”. A cadaveric anatomical study was performed using 18 unembalmed upper limbs. Positive and negative tests were simulated by manipulating the tendons of EPB, Extensor Pollicis Longus (EPL) and Flexor Pollicis Longus (FPL). Changes in tendon tension and joint position were measured and recorded. The EPB anatomy was then determined by dissection. Results: Anatomical variations were present in the majority of wrists, with only 35% of EPB tendons having a distal attachment to the proximal phalanx alone. EPB was absent in 5% of specimens. There was a significant difference between the change in MCPJ position between a positive (36 degrees; 95% CI 25 to 47 degrees) and negative (19 degrees; 95% CI 14 to 25 degrees) clinical test (p = 0.002). Conclusions: The functional importance of EPB depends on its congenital architecture in addition to the functional demands of the patient. We report a novel clinical test which is effective in demonstrating the integrity of the EPB. A positive test result is observed when a change in MCPJ position that occurs while the interphalangeal joint is brought into flexion from full thumb extension is 25 degrees or more.
