Methods: Twenty-eight patients with short oblique (>30°) tibial shaft fractures (AO/OTA 42A2) treated with plate and MIPO technique between 2015 and 2019 were retrospectively assessed.

COMPARISON OF RADIOFREQUENCY ABLATION AND CURETTAGE IN OSTEOID OSTEOMA IN CHILDREN.

Objective: Osteoid osteoma, which is observed in the adolescent and young adult population as benign bone tumors, appears as a single nidus with a diameter < 2 cm and is treated with open surgery. However, technological advances in medicine have made it possible to apply less invasive procedures in surgery.

Methods: Between 2006-2014, 24 patients < 18 years of age were treated for osteoid osteoma.

The biochemical and histological analysis of subcutaneous calcitonin and intramedullary methylprednisolone on bone repair after bone marrow ablation: an experimental comparative study in rats.

Background: Although, glucocorticoid (GC) and calcitonin-induced changes in bone repair have been studied previously, the exact effects of these on fracture healing remain controversial. Hence, the purpose of this experimental study is to determine biochemical and histological effects of locally administrated GC and systemically administrated calcitonin on the kinetics of healing response after bone marrow ablation in rats.

Methods: After having undergone marrow ablation, a steroid-treated group of rats (n = 24) received a single dose of intramedullary methylprednisolone (2 mg/kg), a calcitonin-treated group (n = 24) received intermittently administrated subcutaneous salmon calcitonin (16 IU/kg), and a control group (n = 24) received intramedullary saline (25 μl).

The effect of HIF stabilizer on distraction osteogenesis.

Objective: The aim of this study was to investigate the effect of an orally applicable hypoxia-inducible factor (HIF) stabilizer on distraction osteogenesis (DO) in a rat model.

Methods: The study included 24 Wistar albino rats undergoing osteotomy of the left tibia diaphysis. Rats were divided equally into experiment and control groups.

Approach to supracondylar humerus fractures with neurovascular compromise in children.

Objective: The aim of this study was to evaluate neurovascular compromise in childhood Gartland Type 3 supracondylar humerus fractures (SHFs), identify the factors correlated with increased need of open reduction and compare the clinical outcome of anterior open reduction with that of closed reduction.

Methods: The study included 65 patients (46 male, 19 female; mean age: 7.03 years, range: 1 to 14 years) treated surgically for SCH fracture between January 2002 and June 2008.

Neonatal osteofibrous dysplasia associated with pathological tibia fracture: a case report and review of the literature.

Osteofibrous dysplasia is a rare and benign disease that originates from the tibia or fibula. The symptoms of osteofibrous dysplasia include painless enlargement and bowing of the tibia and pain occurring in the presence of pathological fracture. Herein a male infant who was admitted with redness and swelling on the right leg and diagnosed as pathological tibia fracture due to left tibia osteofibrous dysplasia on the third day of life was presented.

The effect of nicotine on distraction osteogenesis: an experimental study on rabbits.

Background: Tobacco smoke contains more than 4,000 constituents, but not all of them are reported to have adverse effects on bone healing after distraction osteogenesis. No research on the systemic administration of nicotine has been done on distraction osteogenesis of the weight-bearing long bones of the lower extremity.

Methods: Fourteen New Zealand white male rabbits underwent distraction osteogenesis on the right tibia and lengthening by 1 cm.

A comparison of percutaneous and mini-open techniques of Achilles tenotomy: an experimental study in rats.

Purpose: To investigate the effect of Achilles tenotomy performed percutaneously and by mini-open methods on tendon healing and final strength.

Materials And Methods: In two groups, each consisting of 14 rats, percutaneous and mini-open techniques in Achilles tenotomy were compared in terms of biomechanical, histological and gross properties.

Results: In the gross evaluation, it was observed that an obvious thickening and adhesion to the subcutaneous tissue of the healing tendon were observed in nearly all rats in which the mini-open technique was performed.

The effect of tibial lengthening on gastrosoleus muscle function: an electrophysiological study.

Objectives: We evaluated the changes in electrophysiological characteristics of the contraction forces of the gastrosoleus complex due to stretching in experimental tibial lengthening.

Methods: Distraction histiogenesis was performed in 22 guinea pigs weighing 600 to 800 g. Following the application of a semicircular external fixator and right tibial osteotomy, distraction was applied at a rate of 0.

Humoral immunodeficiency in congenital insensitivity to pain with anhidrosis.

Congenital insensitivity to pain with anhidrosis (CIPA) is an autosomal recessive disorder caused by mutations in the neurotrophic tyrosine receptor kinase 1 (NTRK1) gene, which encodes the receptor for nerve growth factor. We report the clinical course of a 7-year-old girl with CIPA and proven NTRK1 mutation. In addition to recurrent dislocation of the left hip joint and avascular necrosis of the left talus, the patient also presented with recurrent infections secondary to hypogammaglobulinemia, a feature not previously known to be associated with CIPA.

Enhancement of tendon-bone healing of anterior cruciate ligament grafts by blockage of matrix metalloproteinases.

Background: The use of soft-tissue grafts for anterior cruciate ligament reconstruction delays the healing process. This delay may be due to biochemical and/or biomechanical insults. We hypothesized that the blocking effect of alpha2-macroglobulin on synovial matrix metalloproteinase activity may enhance the healing of tendon graft in a bone tunnel.

The pathophysiology of Osgood-Schlatter disease: a magnetic resonance investigation.

Osgood-Schlatter disease (OSD) is a well-described clinical condition, although its origin remains controversial. Mechanical, growth or traumatic factors are suggested as causes of this lesion. Thirty-five patients were included in this study.

[Necrotizing fasciitis in the lower extremity secondary to diabetic wounds].

Objectives: The aim of this retrospective study was to evaluate patients who developed necrotizing fasciitis (NF) in the lower extremity secondary to diabetic wounds.

Methods: The study included sixteen patients (11 men, 5 women; mean age 63 years; range 50 to 82 years) who were treated for NF arising from diabetic wounds. Associated diseases were coronary heart disease in three patients, and chronic renal failure due to diabetic nephropathy in three patients.

The effect of alpha-2 macroglobulin on the healing of ruptured anterior cruciate ligament in rabbits.

To investigate the effect of modification of biological environmental conditions, one of the factors influencing the healing of anterior cruciate ligament rupture, we performed experimental anterior cruciate ligament ruptures on New Zealand rabbits. After experimental rupture, intra-articular alpha-2 macroglobulin was injected into the knees of the rabbits in the experiment group to prevent structural changes resulting from the enzymatic reactions in the ruptured anterior cruciate ligament. At the end of 10th day of the experiment, we observed that the anterior cruciate ligaments in the experiment group had retained their prerupture brightness and volume when compared with the control group in which intraarticular alpha-2 macroglobulin had not been injected.
