Biological reconstruction is a useful option for reconstruction following bone sarcoma resection in children. The mid-term functional and radiological outcomes of biological reconstructions after resection of bone sarcomas in children are presented in this study. Eighteen patients [average age 12.5 years (range 4-22 years)] with primary sarcomas of long bones underwent wide surgical resection and biological reconstruction. The bone defects were managed by intercalary (n=14), osteoarticular (n=3) reconstructions and arthrodesis (n=1) with a vascularized fibular graft (VFG). VFG was combined with a massive allograft in seven lower extremity reconstructions. The average follow-up was 45.7 months (range 25-78 months). Graft union and graft hypertrophy was observed in 17 (94.4%) of 18 patients at 12 months. The VFG-allograft osteointegration rate was 100% at 24 months. The average final follow-up Musculoskeletal Tumor Society (MSTS) scores for lower and upper extremity reconstructions were 79.7% (range 66.6-90%) and 80.9% (range 53.3-100%), respectively. Four (22.2%) complications, including nonunion (n=1), implant failure (n=1), infection (n=1) and skin necrosis (n=1), required reoperation. The disease relapsed in three (16.6%) patients. Defect size and VFG length did not correlate with MSTS scores and radiological parameters (P>0.05). Biological reconstruction with VFG can provide permanent stability and progressively increasing functional and radiological results.
The outcomes of the treatment by in situ single screw fixation are negatively affected by increase in the grade of slip, instability of the slip and existence of slip at both hips.
Background: Two main factors determine the strength of tendon repair; the tensile strength of material and the gripping capacity of a suture configuration. Different repair techniques and suture materials were developed to increase the strength of repairs but none of techniques and suture materials seem to provide enough tensile strength with safety margins for early active mobilization. In order to overcome this problem tendon suturing implants are being developed. We designed two different suturing implants. The aim of this study was to measure tendon-holding capacities of these implants biomechanically and to compare them with frequently used suture techniques
Materials and Methods: In this study we used 64 sheep flexor digitorum profundus tendons. Four study groups were formed and each group had 16 tendons. We applied model 1 and model 2 implant to the first 2 groups and Bunnell and locking-loop techniques to the 3rd and 4th groups respectively by using 5 Ticron sutures.
Results: In 13 tendons in group 1 and 15 tendons in group 2 and in all tendons in group 3 and 4, implants and sutures pulled out of the tendon in longitudinal axis at the point of maximum load. The mean tensile strengths were the largest in group 1 and smallest in group 3.
Conclusion: In conclusion, the new stainless steel tendon suturing implants applied from outside the tendons using steel wires enable a biomechanically stronger repair with less tendon trauma when compared to previously developed tendon repair implants and the traditional suturing techniques.
Objective: We aimed to evaluate the reliability of Turkish information achieved from websites about developmental dysplasia of the hip using standardized scientific methods.
Methods:The term "hip dislocation" term was scanned among the most commonly used three internet search engines. The contents of the 10 most frequently clicked sites were copied. These 30 sites were examined. In total, 9 same sites, 3 unrelated sites, and 4 academic sites were eliminated, and 14 sites remained. These sites were scored according to the patient information sheet prepared by the American Academy of Orthopaedic Surgeons. One point was given for every issue included and 0 point was given for no inclusion, over a total of 26 points.Results: With the search of the term "hip dislocation", 141,000 results on Google, 49,600 on Yahoo, and 46,800 on Bing were found. Results of the content points of the 14 sites that were calculated with the created standard form were determined to be an average of 13.5 points out of 26 (min: 5, max: 22, and SD: 5.02).
Conclusion:We determined that the most visited sites in search engines on hip dislocation contained incomplete information. A variety of applications that aim to increase the reliability of information should be undertaken, or more studies about the development of an accreditation system for Turkish language websites should be performed.
