ABSTRACT

The management of displaced radial neck fractures in children is still a controversial topic. The objective of this study is to examine the outcomes of modified Metaizeau technique in the children with displaced radius neck fractures. The retrospective study included 15 children with displaced radial neck fracture with an angulation of more than 30° who were managed with the use of leverage technique by mosquito clamps and internal fixation with elastic stable intramedullary nailing (ESIN). Radiological and functional assessments were performed during follow-up. Additionally, the patients were evaluated using Mayo Elbow Per- formance Score (MEPS). All the children could be managed with clamp-assisted closed reduction. The average duration of follow up was 25.5 ± 6.1 months (15-36 months). An excellent elbow function was achieved in all but one patient. Based on Metaizeau classification, excellent, good, fair, and poor outcomes were achieved in 11, 1, 2, and 1 patients, respectively. The average postoperative MEPS score was 98.7 ± 5.1 (80-100). Clamp-assisted closed reduction and fixation with ESIN is a good choice in the children with displaced radial neck fractures. This technique is associated with good functional and radiologic outcomes in the medium-term. Further studies are warranted with larger sample sizes.

ABSTRACT

Background and objectives: Supracondylar humerus fractures are common in children andcan be surgically treated. However, the general surgical procedures involving reduction andfixation might lead to reduction loss, failure to direct the Kirschner (K)-wire toward the desiredposition, prolonged surgery, or chondral damage. This study aimed to show that temporaryfixation of closed reduction with a fabric adhesive bandage in pediatric supracondylar humerusfractures could maintain reduction so that surgical treatment can be easily performed by a singlephysician. Materials and Methods: Forty-six patients with Gartland type 3 supracondylar humerusfractures who underwent surgical treatment between May 2017 and June 2018 were retrospectivelyevaluated. Fluoroscopy-guided reduction and fixation were performed from the distal third of theforearm to the proximal third of the humerus using a fabric adhesive bandage. Two crossed pinswere applied on the fracture line by first inserting a lateral-entry K-wire and then inserting anotherK-wire close to the anterior aspect of the medial epicondyle and diverging from the ulnar nervetunnel. A tourniquet was not applied in any patient and no patients required open reduction.Results: The study included 32 boys (69.6%) and 14 girls (30.4%) (mean age, 7.1; range, 2-16 years).The mean hospital stay and follow-up duration were 4.3 ± 3.9 days and 48.1 ± 14.3 weeks,respectively. Heterotopic ossification was detected in one patient, and ulnar nerve neuropraxia wasdetected in another patient. Functional (according to Flynn criteria) and cosmetic outcomes wereexcellent in 95.6%, moderate in 2.2%, and poor in 2.2% of patients. The mean duration of fixation ofthe closed reduction with a fabric adhesive bandage was 8.1 ± 3.9 min, and the mean duration ofpinning was 7.9 ± 1.4 min. Conclusions: Temporary preoperative fixation of supracondylar humerusfractures that require surgical treatment with a fabric adhesive bandage may be significantlyconvenient in practice.

ABSTRACT

OBJECTIVE: Extensive bone defects remain a therapeutic challenge necessitating alternative surgical approaches with better outcomes. Can increase the effectiveness of PRP or EGF treatment in surgical treatment of large bone defects with Masquelet technique? Aim of this study examined potential therapeutic benefits of the Masquelet technique with induced membranes in combination with platelet-rich plasma (PRP) or epidermal growth factor (EGF) in a rat model of segmental femur defect. METHODS: Three groups each consisting of 20 Sprague-Dawley rats were defined as follows: EGF group, PRP group, and control group. A femoral bone defect was created and filled with antibiotic embedded polymethyl methacrylate. Half of the animals in each group were sacrificed at week 6 and the pseudo-membranes formed were analyzed. In the remaining half, the cement was removed and the space was filled with autograft. After another 6 weeks, the structures formed were examined radiologically, histologically, and biochemically. RESULTS: At week 6, both PRP and EGF groups had significantly higher membrane CD31, TGF-beta, and VEGF levels than controls. At week 12, when compared to controls, PRP and EGF groups had significantly higher membrane CD31 levels and the PRP group had significantly higher membrane TGF levels. Regarding bone tissue levels, PRP and EGF groups had significantly higher VEGF levels and the EGF group had significantly higher BMP levels. In addition, PRP and EGF groups had higher radiological scores than controls. However, the two experimental groups did not differ with respect to any parameter tested in this study. CONCLUSION: Both PRP and EGF seem to be associated with histological, biochemical, and radiological improvements in experimental rat model of Masquelet technique, warranting in further clinical studies. LEVEL OF EVIDENCE: Level 5.
