Periosteal chondrosarcomais a rare low-grade malignant cartilaginoustumor arising from the external surface ofbone. Imaging features are often specific. Recognizingperiosteal chondrosarcoma and differentiatingit from other surface tumors is of capitalimportance because the prognosis is excellentafter adequate local surgery alone.2- Tramadol as an adjuvant to lidocainefor axillary brachial plexus blockKaabachi O, Ouezini R, Koubaa W, Ghrab B, Zargouni A, Ben Abdelaziz A.Service d’anesthésie réanimation, Institut Kassab d’Orthopédie, Ksarsaid, Tunis, Tunisia. olfa.kaabachi@gnet.tnAnesth Analg. 2009 Jan;108(1):367-70.BackgroundIn this prospective randomized study, we evaluatedthe effect of tramadol as an adjuvant to axillaryblock.methodsWe studied 102 patients scheduled for hand surgeryunder axillary block with lidocaine 1.5%(epinephrine 1/200,000) and the addition of either4 mL saline (control group), 100 mg tramadoland 2 mL saline (TL group), or 200 mg tramadol(TH group).resultsOnset time was longer in the TH group, 16 +/- 7min (9 +/- 3 min in control group; P = 0.01). Sensoryblock and time for first rescue analgesia weresignificantly prolonged in the TH group comparedwith both TL and control groups (265 +/- 119min vs 190 +/- 87 min vs 126 +/- 48 min; P =0.018); (734 +/- 434 min vs 573 +/- 516 min vs375 +/- 316 min; P = 0.02).ConclusionsThe benefit of block prolongation associated withthe addition of 200 mg tramadol to lidocaine duringaxillary block is limited by the slow onset ofthe block.3- Acute tibial tubercle avulsion fracturesin the sporting adolescentZrig M, Annabi H, Ammari T, Trabelsi M, Mbarek M, Ben Hassine H.Department of Orthopaedic and Traumatic Surgery, Aziza Othmana Hospital,Tunis, Tunisia. zrigmak@yahoo.frArch Orthop Trauma Surg. 2008; 128(12):1437-42.introductionThe authors report 7 cases of acute tibial tubercleavulsion fractures. The fracture occurred in 6 outof the 7, after an abrupt tension of the patellartendon in male sporting adolescents (age 13-17years). Two patients presented symptoms of homolateralOsgood-Schlatter’s disease before thelesion.methodAccording to Ogden’s classification, the tibial tubercleavulsion fracture was not displaced in 3cases (stage IA) and was treated conservatively byimmobilization for 6 weeks. In 4 cases, the fracturewas displaced and necessitated an internalfixation with plaster for about 6 weeks. A torn patellartendon was noted in one adolescent havinga stage IIIB avulsion fracture.resultThe mean follow-up was of 4.5 years (1.5-7.5years). The results were satisfactory: completefunctional recovery, resumption of sport at theprevious level and absence of recurvatum.4- Anthropometric, physiological andperformance characteristics of eliteteam-handball playersChaouachi A, Brughelli M, Levin G, Boudhina NB, Cronin J, Chamari K.Scientific Research Unit, Evaluation, Sport, Health, National Centre ofMedicine and Science in Sports, Tunis, Tunisia.J Sports Sci. 2008 Nov 29:1-7.
