Two low invasive laser technologies for treatment of degenerative-dystrophic bone diseases in children are presented. The first is the transcutaneous laser osteoperforation developed by us and initially applied for treatment of different inflammatory and traumatic diseases (osteomyelitides, osteal and osteoarticular panaritiums, delayed unions, false joints, and others). Now the technology was applied to treatment of aseptic osteonecrosis of different localizations in 134 children aged from 1 to 16 years, including 56 cases with necrosis of femoral head (Legg-Calve-Perthes disease), 42 with necrosis of 2 nd metatarsal bone head (Kohler II disease), and 36 with necrosis of tibial tuberosity (Osgood-Schlatter disease). The second technology is the laser intracystic thermotherapy for treatment of bone cysts. The method was applied to 108 children aged from 3 to 16 years with aneurismal and solitary cysts of different localizations. In both technologies a 970 nm diode laser was used. The suggested technologies increase the efficiency of treatment, reduce its duration, can be performed on outpatient basis, which resulted in great economical effect.

Introduction: Avascular necrosis (AVN) of the femoral head is a devastating disease that often leads to the destruction of the hip. Core decompression of femoral head is the commonest of all conservative surgical treatments where an 8-10 mm cylindrical core of bone is removed from antero-lateral segment of the femoral head. But it is employed only in early stages of the disease and its results are still of controversial efficacy and most of patients ultimately require total hip arthroplasty. Laser irradiation stimulates the reparative process in the bone and marrow while local hyperthermia produced by the laser vaporizes some of necrotic areas leading to a reduction of the intraosseous pressure which is the fulcrum of AVN regardless of the cause. Objectives: The aim of this experimental study was to evaluate the outcome of core decompression by laser osteoperforation for AVN of the femoral head. Subjects and methods: The study was carried out at the Institute of Laser Surgery and Hospital, Dhaka, Bangladesh which included 62 hips with AVN in 40 patients. Preoperative and Postoperative Clinical assessment and Radiological staging were done using 'Harris Hip Score (HHS)' and 'Ficat and Arlet staging' respectively. Under spinal anesthesia and Fluoroscopic guidance all hips were subjected to 'Core decompression by Laser Osteo-perforation' using 970 nm Diode laser through 18G spinal needle via transtrochanteric and trans-capital approach. Results: All patients were followed up at intervals of three weeks, three months, six months and then yearly (cases with minimum 3 follow ups were included in this study). According to HHS our results are as : 40.3% -excellent; 21.0% -good; 29.0% -fair; 9.7% -poor. No significant side effects or complications were observed so far. Conclusion: Core decompression by laser osteoperforation has been proven so far to be an effective, safe and minimally invasive treatment modality for AVN of the femoral head.

Introduction No data on experimentally substantiated parameters and modes of diode laser radiation allowing a minimally traumatic surgical treatment of intrauterine pathology have been found in the literature.The aim of the investigation was to substantiate experimentally the optimum parameters and modes of diode laser radiation in the treatment of intrauterine pathology based on the study of morphological changes in the endometrium.Materials and methods 48 endometrial samples were exposed to 10-40 W diode laser power in a constant mode and 15 samples - in a pulsed mode with 3 different sets of laser exposure parameters. The data were statistically processed using Microsoft Excel spreadsheets, version 16.49. The differences were considered statistically significant at р<0.05.Results Width of the ablation zone, lateral coagulation and hyperthermic exposure zone was calculated at the most optimal parameters of laser energy (20 W), achieving adequate cutting and bleeding properties of the laser. The most effective in the pulsed mode of laser operation was 30 W amplitude power of radiation, the pulse duration of 100 ms, the duration of the interval between pulses of 50 ms, the average power of 20 W.Discussion Comparative analysis of morphometric parameters in the action of laser radiation in the constant mode with a radiation power of 20 W and in the pulsed mode with an average laser power of 20 W has shown that the structural parameters have significantly lower values in the pulsed laser mode.Conclusion Optimal cutting properties of the laser are observed when constant laser irradiation with a power of 20 W is used. The best cutting and bleeding properties were demonstrated by the pulsed laser mode with an average power of 20 W, amplitude power of 30 W, pulse duration of 100 ms, and inter-pulse interval of 50 ms.
