當您想到肢體延長裝置時,您會很想擁有可以通過每天將四肢慢慢分開一定量來使四肢變長的裝置。根據這些設備中開發的技術,隨著時間的推移發生了巨大的變化。就延長能力、價格、並發症和設備構造等標準而言,外部和內部延長設備之間存在根本差異。

一、裝置結構

肢體延長裝置通常分為外部裝置和內部裝置兩種。外固定器是一種外科手術方法,其中將桿擰到骨頭上並從身體中取出並連接到身體外部的穩定結構上。提供延長和固定的結構位於肢體外部。內部方法是用螺絲固定在長骨內側的電動釘子。先進的內釘具有遠程控制系統,該系統放置在您的肢體外部並加長指甲。

2、加長能力

內部電動釘通常具有 8-9 厘米的伸長能力。在外部設備中,這個數字可能會略高。但是,肢體延長的量通常取決於您的延長過程,而不是設備。安全應始終是重中之重。延長過程中可能出現的並發症以及軟組織對延長的耐受性將決定您將達到的最大延長量。由於內部裝置的並發症和疼痛程度較低,因此採用這種方法的患者通常會達到更高的延長水平。

3.並發症

在復雜性方面,內部設備比外部設備有很大的優勢。外部設備通過從外部刺穿肌肉和骨骼來提供與身體內部的連接。這會增加感染的風險。應注意進入身體的入口處的衛生和包紮。內部方法沒有這種風險。

由於外接裝置在體外,體積大,給患者的行走、臥床轉移、運動等日常活動和運動帶來困難。儘管這些外部設備的尺寸和重量隨著時間的推移而減小,但與內部設備相比,這種困難仍然存在。

在外部設備中看到的運動和運動限制會導致肌肉短促、關節攣縮、ROM 減少和行走困難。這會影響您的延長能力和質量。

當根據疼痛進行評估時,觀察到使用外部設備的人疼痛更嚴重。不應單獨考慮疼痛標準,因為疼痛會影響一個人的心理、睡眠質量、動機和運動能力。疼痛對於延長過程的質量非常重要。

由於內部裝置放置在骨骼中,因此沒有感染的風險,也不會導致運動受限。痛苦遠小於外用方法。很明顯,內部設備在並發症方面具有很大優勢。

4.價格

內釘的價格遠高於外釘。這是因為內電動釘是高科技產品。為減少並發症和增加患者舒適度而開發的內釘帶來了價格高的缺點。

Avatar of Prof. Dr. Mustafa Uysal
Prof. Dr. Mustafa UYSAL was born in 1972. After completing his education at Aydin Gazipaşa Middle School 1983-1986, he studied his bachelor's degree at one of the most prestigious universities, Istanbul University, Cerrapaşa Faculty of Medicine (English Department) between 1990-1997. After his graduation, continued his education in both Istanbul University's Medical School, Department of Orthopedics and Traumatology and in Department of Orthopaedics and Traumatology, Baskent University School of Medicine. After having experience in the Orthopedics and Traumatology Department in Baskent University's Medical School between 2009-2019 years, has started to work in the private Adatip Sakarya Hospital between 2019 and 2020. The professor is currently employed at Sakarya's private Medar hospital. He has been using the latest technologies both for deformity corrections and orthopedic surgeries such as hip replacement, scoliosis, and knee replacement. Furthermore, he has been performing limb lengthening surgeries both for functional and cosmetic reasons since the early 2000's. The Professor has attended a training program in the Paley Institute, and he has not only published many articles on himself and also in the global framework. He has participated in a book that can be defined as a precious global guide that has the contents of Mr. Dr. Dror Paley's as well, called "Basic Techniques for Extremity Reconstruction." The doctor, for his part, has highlighted the Ilizarov technique's osteotomy rules and types, as well as the treatment of complications.
