    Medial patellofemoral ligament reconstruction in skeletally immature patients
    (SAGE Publications Ltd, 2014) Yercan H.S.; Kale G.; Erkan S.; Özalp T.; Okcu G.
    Objectives: To evaluate the clinical outcome after medial patellofemoral ligament (MPFL) reconstruction for patellofemoral instability in skeletally immature patients. Methods: Study participants were 8 patients (median age, 10 years; range, 5-14 and one male, others female) who had suffered from persistent patellofemoral instability. Our technique preserves femoral and patellar insertion anatomy of MPFL using a free semitendinosus autograft, together with tenodesis to the adductor magnus tendon thus sparing the open physis of distal femur and the patellar attachment of MPFL. The clinical results were evaluated preoperatively and the final follow-up period using the Kujala patellofemoral score. Patellar shift, tilt and height were measured preoperatively and on the latest follow-up on plain radiographs. Results: At average 42 months follow-up (range, 16 to 56), %80 of patients were satisfied with the treatment. Redislocation or instability symptoms occurred in two patients. No apprehension signs or redislocations were seen in the remanining six patients. A significant improvement (p<0.05) in Kujala score (from 36 to 77) was found. Patellar shift & tilt decreased to anatomic values in six patients but patella alta persisted. Conclusion: The result of this study show that MPFL reconstruction with our technique seems to be an effective treatment for recurrent and habitual patellofemoral dislocation in skeletally immature patients; leading to significant increases in stability and functionality. © The Author(s) 2014.

    Scaphoid nonunion treated with vascularised bone graft from dorsal radius
    (Elsevier Ltd, 2015) Özalp T.; Öz Ç.; Kale G.; Erkan S.
    Introduction The main aim of this retrospective study was to present our experience on scaphoid nonunion treated with vascularised bone graft. Methods Between 2006 and 2012, 58 patients presenting with symptomatic scaphoid nonunion were eligible to participate in this study. Topography of the nonunion included 29 proximal, 25 waist and 4 distal scaphoid nonunions. Vascularised bone graft from distal dorsal radius was used in all cases which were stabilised with the headless cannulated compression screws. Scapholunate angles, Natrass carpal height ratio were evaluated pre and postoperatively. Range of motion of the affected side was compared to that of the contralateral side after the surgery. Results Radiographic union was achieved in 50, out of 58 cases with an average time of 9.9 weeks (range, 6-18 weeks). Out of all the non-united cases, four of them were in proximal, three in the waist and one was in distal scaphoid. In nine proximal nonunions treated by 4 + 5 ECA graft all but one were united. The mean follow up was 21.7 months (12-62 months). The flexion was 91.6%, the extension was 91.5%, the radial deviation was 81.2%, and the ulnar deviation was 89.5% compared to the other side. The grip strength was 93%. Preoperative DASH score was 61.5 diminishing to 28.7 postoperatively. There was no significant change in Natrass carpal height ratio but a slight improvement occurred in scapholunate angles both pre and postoperatively. Conclusion Vascularised bone graft is a good solution for scaphoid nonunion to enhance the healing rate especially in the presence of avascular necrosis. Proximal pole nonunions, humpback deformity and smoking are important negative factors for scaphoid nonunion despite the use of a vascularised bone graft. A trapezoidal wedge graft is necessary for the volar type nonunions with humpback deformity. 1,2 ICSRA offer an advantage with its proximity to scaphoid in all nonunion locations. Nonetheless, 4 + 5 ECA graft is also a good solution for proximal nonunions. © 2015 Elsevier Ltd. All rights reserved.
