Anatomical Variation of Iliolumbar Artery and its Clinical Significance

Abductor pollicis longus (APL) muscle is known to exhibit different variations with respect to its attachments. Various studies have reported the splitting of the APL muscle. Comparative anatomical findings of split insertion of APL is commonly found in chimpanzees, gorillas and gibbons. In the present study, we describe an anomalous APL muscle, which originated from the posterior surface of the shaft of the radius and ulna and traversed a course deep to the extensor retinaculum. Interestingly, immediately after emerging form the deeper aspect of extensor retinaculum, the thin tendon of the APL muscle continued again as a muscular belly in relation to the dorsolateral part of the 1st metacarpal bone, to end as a tendon with its attachment to the base of the proximal phalanx. Such an unusual variation of APL with its attachment into proximal phalanx is a rare finding and may be of importance in altering the mechanics of the thumb during abduction. The clinical significance of such an anatomical variation of APL may be important during reconstructive surgeries involving thumb and also of academic interest.

Objective. The aim of our paper is to depict an anatomical variation of the brachial plexus, concerning a communicating branch between the median and the musculocutaneous nerve and its clinical significance. Anatomical variations of the brachial plexus and especially those of the musculocutaneous nerve are quite common. Awareness of these variations is of paramount importance in clinical practice, mainly in achieving best results in minimal invasive or surgical procedures.Case Report. After dissection in upper extremities in a 89-year-old male cadaver, a communicating branch between the median and the musculocutaneous nerve was found. This communicating branch was formed before the musculocutaneous nerve perforated the coracobrachialis muscle. It also derived from the level of the ansa medianis and its course was of an approximately 2cm length.Conclusion. The clinical significance of our study is the entrapment of the musculocutaneous nerve that may cause clinical findings similar to those of the carpal tunnel syndrome.

Background: Anatomical variation and deficits of velocardiofacial syndrome patients are related to unsatisfactory treatment results in surgical correction of speech abnormalities. The main purpose of the article is to investigate the clinical significance of thinned levator veli palatini muscle in VCFS patients. Methods: The authors reviewed medical records of all children with velocardiofacial syndrome who received pharyngeal flap surgery between March 2007 and September 2015. Data including thickness of levator veli palatini in magnetic resonance examination; preoperative velopharyngeal gap size from nasoendoscopy; and preoperative and postoperative speech outcomes were collected. Results: Total of 36 velocardiofacial syndrome patients with preoperative objective data and postoperative speech outcomes were identified. Preoperative velopharyngeal gap showed significant correlation with thickness of levator veli palatini (correlation coefficient: 0.297/0.397, P = .02/.03) and gap size showed correlation with postoperative speech improvement (0.347/0.413, P = .04/.02). However, muscle thickness showed no correlation with speech outcomes (0.046/0.037, P = .77/.86). Conclusion: Thinned levator veli palatini muscle in velocardiofacial syndrome patients are related to widened velopharyngeal gap and production of hypernasal speech, and can give negative impact on postoperative surgical outcome of pharyngeal flap surgery.
