Aims: The evaluation of the results of surgical treatment of humeral shaft fractures with intramedullary nailing (I.N.) after twelve month follow up. Methods: This study involves 18 patiens with fracture of the humeral shaft, treated operatively with I.N. of A.O. type, in a 4-year period (Jan 1998- Feb 2001). 17 were available to follow up examination. 16 men and 2 women with average 25 years of age were followed for a mean period of a year. Indication for the prosedure was the inability to maintain closed reduction. In 11 patiens the nail was inserted below the great tuberosity. The rest underwent retrograde I.N. All nails were proximally locked and x- were distally locked too. Closed reduction was achieved in 15 cases. The nail was inserted manually (with no hammer use) in all cases. Results: Clinical and radiological healing was apparent in all fractures between the 4th and 6th p.o. month. Full active motion was achieved in 8th p.o. week. There were 3 p.o. radial nerve palsies. Two of them resolved six months later. Residual pain of the shoulder was noted in one case. Conclusions: Nailing of the humeral shaft fractures using AO-type nail is a reliable method of treatment, giving very good final results. Advantages are: minimal surgical trauma, less blood loss, shorter operative time and earlier mobilization.

Aims: The purpose of this study is to evaluate the results of intrerlocking nailing (ILMN) as a þnal treatment of non septic femoral shaft pseudarthrosis. Material- Methods: The study involved 35 patiens suffering a femoral pseudarthrosis who underwent þxation with ILMN as a þnal treatment between 1999–2001. 31 male and 4 female individuals with a mean age of 25 years were followed up postoperatively for 24 months. Primary treatment had been done with plating in 29 pts, external þxation in 2 pts, AO nail in 3 and R-Tnail in one patient. The period between primary and þnal treatment ranged from 9 to 46 months. After the removal of primary þxation components all patients treated with ILMN for þxation but only 8 of them underwent autogenous bone grafting. Dynamic ILMN has been done in 32 out of 35 patiens (91%)Results: Clinical healing and radiological callus formation was apparent in all patiens after a period of 18 to 26 weeks (average time 20w). Serious complications were not observed. Light stiffness of the knee joint was noted in one and residual pain in distal metaphysis in two cases. Conclusions: The sort- term results from the use of LIN in treatment of femoral shaft pseudarthrosis have been more than encouraging. We recommend the reaming technique and the dynamization of the nail for optimal outcome. Bone grafting is not necessary.
