Event Description
This report is being filed after the review of the following journal article: thompson, n. Et al (2010), the use of minimally invasive techniques in multi-level surgery for children with cerebral palsy: preliminary results, the journal of bone and joint surgery. British volume, vol. 92-b (10), pages 1442-1448, https://doi. Org/10. 1302/0301-620x. 92b10. 24307 ((b)(6)). The aim of this prospective cohort study is to describe the preliminary results of a pilot study comparing the outcomes of minimally invasive single-event multi-level surgery with conventional multilevel procedures. A total of 10 patients with a mean age of 10. 6 years (7. 11 to 13. 9) had minimally invasive surgery on 18 limbs. These patients were matched for ambulatory level and compared with 10 patients with a mean age of 11. 4 years (7. 9 to 14. 4) who underwent conventional multi-level surgery on 20 limbs. In 10 patients, calcaneal osteotomies were fixed with a small fragment ao plate (synthes inc. , (b)(4)) to achieve immediate stability. An innovative technique was used for derotation osteotomy of the femur and tibia, based on closed corticotomy and fixation with the titanium elastic nails (synthes inc. ). Femoral derotation osteotomy was performed in all cases while tibial derotation osteotomy in 1 case (table 1). The mean follow-up period was unknown. The following complications were reported as follows: minimally invasive group: patient 2: a (b)(6) male patient developed a transient left trochanteric bursitis. Patient 3: a (b)(6)male patient developed transient neuropathic pain in the right foot. In an unknown number of patients, there was a significant reduction of knee flexor strength (p < 0. 001) at 12 months compared with pre-operatively, but improved strength in the hip abductors and knee extensors at 90¿ and 30¿. Conventional group: patient 20: a (b)(6) female patient had failure of fixation requiring revision when she fell at home five weeks postoperatively. In an unknown number of patients, muscle strength was reduced at 12 months compared with pre-operatively in all lower-limb muscle groups, except for the hip abductors (fig. 2). This report is for an unknown synthes elastic nail. It captures the reported (b)(6) male patient who developed a transient left trochanteric bursitis. A copy of the literature article is being submitted with this medwatch. This is report 3 of 7 for (b)(4).
