  • Bilateral Anomalous Muscle in the Popliteal Fossa & Its Clinical
    International Journal of Anatomy and Research, Int J Anat Res 2014, Vol 2(4):614-16. ISSN 2321- 4287 Case Report DOI: 10.16965/ijar.2014.501 BILATERAL ANOMALOUS MUSCLE IN THE POPLITEAL FOSSA & ITS CLINICAL SIGNIFICANCE Sowmya S *, Meenakshi Parthasarathi, Sharmada KL, Sujana M. Department of anatomy, Bangalore Medical College & Research Institute, Bangalore, India. ABSTRACT Muscle variation may occur due to genetic or developmental causes. Some variations may compromise the vascular, muscular or nervous system in the region. Bilateral muscle variation in popliteal fossa is very rare. In present study an instance of bilateral muscle variation in popliteal fossa, arising from different muscles like gastrocnemius and from biceps femoris is recorded. There is no report of such variations. These observations are rare of its kind because of bilateral asymmetrical presence and difference in the origins in different legs. This is the first report as for the literatures available. Clinical and functional importance of such variation is discussed with the morphological aspects of this anomalous muscle.

  • The Square Flap Technique for Burn Contractures: Clinical Experience and Analysis of Length Gain
    Annals of Burns and Fire Disasters - vol. XXXI - n. 4 - December 2018 THE SQUARE FLAP TECHNIQUE FOR BURN CONTRACTURES: CLINICAL EXPERIENCE AND ANALYSIS OF LENGTH GAIN DOUBLE LAMBEAU RHOMBOÏDE POUR BRIDE SÉQUELLAIRE DE BRÛ- LURE: EXPÉRIENCE PRATIQUE ET ANALYSE DE LA LONGUEUR GAGNÉE Hifny M.A. Department of Plastic Surgery, Faculty of Medicine, Qena University Hospital, South Valley University, Egypt SUMMARY. Post-burn contractures, affecting the joints especially, are demanding problems. Many surgical techniques have been designated for burn contracture release. The aim of this study is to investigate the efficiency of the square flap technique to release a post-burn scar contracture, and assess the post-operative length gain that can be achieved by simple mathematical calculation. In this study, sixteen patients with linear contracture bands were treated with the square flap tech- nique. The anatomical distribution of the contractures was: axilla, cubital fossa, flank, perineum and popliteal fossa. Scar maturity ranged from 4 months - 9 years. Square flap width and contracture band length before and immediately after surgery were recorded by simple mathematical calculation. Flap complication was assessed. Patient satisfaction was also assessed during the follow-up period. All square flaps were effective in lengthening the contracture bands. The length of the contracture that was released ranged from 2 to 6 cm. The gain in length provided with this technique ranged from 212 to 350%, average 247%, and adequate contracture release was achieved in all cases postoperatively. All square flaps healed uneventfully except for one (6%), which demonstrated limited epidermolysis that healed by secondary intention. The fol- low-up interval ranged from 6 months to 1.5 years.
