In this study, the results of open-wedge osteotomy with Puddu plate for the treatment of varus gonarthrosis have been evaluated prospectively. This study assessed 65 knees of 60 patients with varus gonarthrosis who underwent high tibial osteotomies. Our study population consisted of 13 male and 47 female patients with a mean age of 54 (range 39-76) years. For the clinical evaluation of the patients Hospital of Special Surgery (HSS) score, American Knee Society and Oxford knee scores, and for the radiological assessment mechanical axis deviation (MAD), lateral distal femoral angle (LDFA), medial proximal tibial angle (MPTA), femorotibial angle and Insall-Salvati index were basically taken into consideration. Our patients were followed up for an average of 34 (range 18-60) months. In the last assessments of our cases, mean improvements detected in HSS scores, Oxford knee scores, knee and functional scores of Knee Society were 26.72, 19.18, 49.9, and 30 points, respectively. The radiological examinations revealed that their mechanical axes on the average passed 5.09 mm laterally achieving an average of 6.5 degrees genu valgum, and a mean Insall-Salvati index of 1.09. As complications, superficial wound infection in two patients (3%), implant infections in one patient (1.5%), deep vein thrombosis in two patients (3%), peroperative lateral tibial plateau fracture in one patient (1.5%), and postoperative lateral tibial plateau fracture due to a falling down were encountered. According to the results obtained, postoperative pain resolves promptly and a significant degree of improvement of knee functions of the patients are achieved. Therefore, we believe that high tibial osteotomy with a Puddu plate is a valuable alternative to total knee arthroplasty in cases with varus gonarthrosis. Although early results are satisfactory, long-term follow-up studies are required especially in the middle aged and elderly patient populations.
One-stage reimplantation for the salvage of infected total knee arthroplasty in 18 patients was reviewed at an average follow-up of five years. There had been one recurrence and one new infection, both in rheumatoid patients with another focus of infection. In four other patients the clinical result was impaired by pain after walking (2) and limited flexion (2). Our results suggest that one-stage reimplantation is a reasonably reliable procedure for the management of a loose infected prosthesis.
Our results show that the Ponseti technique is reproducible and effective in children at least up to 12 months of age. It can also produce good correction in children presenting with complex idiopathic deformities. Therefore, extensive joint releases should not be considered immediately in such cases. The treating surgeon should be meticulous in using the technique and ensure compliance to foot abduction brace in order to avoid recurrences.
Our findings suggest that lumbar- or proximal femur-DEXA, rather than forearm- or total body-DEXA, could reveal significantly decreased BMD in children with NF1, especially in those with skeletal involvement of NF1.
Non-compliance with periods of intolerance is very common for children during orthosis treatment. Parents' coping strategies are very important to avoid relapses. It is important to develop strategies to guide parents.
Dega acetabuloplasty at the time of open reduction is effective in improving the acetabular coverage of the femoral head, hence improving the stability of reduction and preventing possible surgery in the future for residual acetabular dysplasia in older children with Tönnis grade 3 and 4 developmental dysplasia of the hip (DDH). The aim of this study was to assess the radiological results of open reduction combined with Dega osteotomy in DDH. Twenty-two children's 26 hips were operated on at a mean age of 38±20.4 SD months and followed up for an average of 42 (range 24-108) months. Thirteen hips (50%) were operated on with concomitant open reduction and capsulorrhaphy, and 13 hips (50%) were treated with concomitant open reduction, capsulorrhaphy and femoral shortening osteotomy. Radiological examination included acetabular index (AI) and centre edge angle measurements. The mean preoperative AI was 39.4±6.9° SD, which improved to 18.3±4.5° SD postoperatively, and AI was measured as 15±3.5° SD at the latest follow-up. There was a significant difference in the mean AI values between the last follow-up and the preoperative measurements (P<0.05). The mean centre edge angle was 31±5.6° SD postoperatively, and it was 31±6.2° SD at follow-up. There was no significant difference between the two values. Two hips were noted to have lateralization of the femoral head due to coxa valga anteverta. One of them was operated with a femoral varus osteotomy. The Dega osteotomy combined with anterior open reduction and femoral osteotomies is a safe and effective acetabular osteotomy for surgical treatment of severe DDH such as Tönnis grade 3 and 4 dislocations.
Hypertrophic nonunions can be managed successfully with distraction. The Ilizarov device can address every aspect of a stiff hypertrophic nonunion, including shortening and deformity.
