Abstract
У багатьох галузях медицини широке застосування отримали імплантати з різних синтетичних та природних біоматеріалів. Серед матеріалів, що частіше використовують для створення імплантатів, полілактид (PLA), особливістю якого є біодеградація в ділянках імплантації, остеоінтеграція, здатність індукувати процеси утворення кісткової тканини та висока біосумісність з організмом. Мета огляду: проаналізувати та узагальнити дані щодо перебудови в кістці біорезорбуючих біоматеріалів на основі полілактиду та визначити тенденції розвитку проблеми. В огляді літератури подано загальну характеристику та визначено історичні віхи розвитку проблеми та використання деградуючих полімерів у кістковій хірургії. Надані дані щодо факторів, що впливають на біодеградацію в кістках цього біоматеріалу, та визначено особливості його остеоінтеграції залежно від складу. Наведено дані щодо використання PLA та співполімерів у кістковій хірургії та регенераторній медицині. Важливим напрямком майбутніх досліджень буде розробка композитних біоматеріалів на основі PLA з бажаними якостями остеоінтеграції та керованою біодеградацією. Подано нові тенденції розвитку напрямку використання в кістковій хірургії імплантатів на основі композитних матеріалів, виготовлених на основі PLA, та новітні способи створення імплантатів та композитів із використанням 3D-принтера.

Abstract
Orthopedic implants requiring osseointegration are often surface modified; however, implants may shed these coatings and generate wear debris leading to complications. Titanium nanotubes (TiNT), a new surface treatment, may promote osseointegration. In this study, in vitro (rat marrow-derived bone marrow cell attachment and morphology) and in vivo (rat model of intramedullary fixation) experiments characterized local and systemic responses of two TiNT surface morphologies, aligned and trabecular, via animal and remote organ weight, metal ion, hematologic, and nondecalcified histologic analyses. In vitro experiments showed total adherent cells on trabecular and aligned TiNT surfaces were greater than control at 30 min and 4 h, and cells were smaller in diameter and more eccentric. Control animals gained more weight, on average; however, no animals met the institutional trigger for weight loss. No hematologic parameters (complete blood count with differential) were significantly different for TiNT groups vs. control. Inductively coupled plasma mass spectrometry (ICP-MS) showed greater aluminum levels in the lungs of the trabecular TiNT group than in those of the controls. Histologic analysis demonstrated no inflammatory infiltrate, cytotoxic, or necrotic conditions in proximity of K-wires. There were significantly fewer eosinophils/basophils and neutrophils in the distal region of trabecular TiNT-implanted femora; and, in the midshaft of aligned TiNT-implanted femora, there were significantly fewer foreign body giant/multinucleated cells and neutrophils, indicating a decreased immune response in aligned TiNT-implanted femora compared to controls.

Abstract
PURPOSE The objective of this study was to evaluate the immediate bone damage and bone repair after osteotomy for implants using conventional drills and drills powered by piezoelectric motor. MATERIALS AND METHODS Twelve rabbits received a tibial osteotomy with a conventional drill (control), with a diamond like carbon drill (DLC) and with a piezoelectric drill (Piezo). The animals were euthanized immediately, 30 and 60 days postoperatively. The tibias were removed and analyzed by means of histomorphometry, immunohistochemistry and microtomography. RESULTS The immediate damage to the tissue at the cavity margins was similar (P > .05). At 30 and 60 days, the amount of newly formed bone tissue was similar (P > .05). Osteocalcin was intense score at 60 days in Piezo group. Microtomography revealed that bone volume at 30 days (control 3.8; DLC 4.3; and Piezo 2.4) and 60 days (control 4.9; DLC 4.82; and Piezo 3.95) were similar. There was a significant difference in bone formation between 30 (2.4) and 60 days (3.95) for the Piezo group (P = .016). CONCLUSION The immediate effects and repair of cavities made using conventional, DLC coated, or ultrasound drills were similar.
