Abstract

Purpose: To present the design, clinical application, and outcomes of a novel three-dimensional external hinge distraction fixation system (Salamehfix 1), allowing simultaneous limb lengthening and correction of axial deviations with stable fixation, early mobility, and full weight bearing.

Methods: Between 2000 and 2024, a total of 1103 patients (aged 4-57.5 years) underwent lower limb reconstruction using Salamehfix 1. Indications included congenital limb length discrepancy (LLD), post-traumatic and developmental deformities, stature lengthening, achondroplasia and cosmetic lengthening. Using (Salamaehfix 1), 640 patients out of the total 1103 underwent simultaneous lengthening and deformity correction and 193 patients were stature lengthening cases. The device employs three small anterior arcs with hinged distraction rods, customizable to patient anatomy and deformity pattern. Additionally, the device is an arc hinged system with pins in different angles and levels to provide a stable bone fixation and weight bearing. Outcomes were assessed in terms of gained bone's length, functional mobility, healing time, and complication rate.

Results: Mean bone lengthening was 5.6 cm (range: 2-18 cm), and bone healing time of 260 days. Complications were minimal and manageable; superficial pin site infection occurred in 25 patients, contractures in 9, and deep infection in one. Stature cases (n = 193) had a mean lengthening of 6.5 cm, with excellent functional outcomes.

Conclusion: Salamehfix 1 is an effective, patient-friendly external fixation system enabling simultaneous correction and lengthening in a wide variety of deformities and cosmetic cases. It offers significant mechanical and clinical advantages over traditional devices.

用于腿延长和轴向偏差矫正的外铰链固定系统，/ Salamehfix 1/。配置与临床优势。

目的：介绍一种新型三维外铰链牵引固定系统（Salamehfix 1）的设计、临床应用和结果，该系统可以同时延长肢体并在稳定固定、早期活动和完全负重的情况下纠正轴向偏差。方法：2000年至2024年间，共有1103例患者（年龄4-57.5岁）采用Salamehfix 1进行下肢重建。适应症包括先天性肢体长度差异（LLD），创伤后和发育畸形，身材延长，软骨发育不全和美容延长。使用（Salamaehfix 1）， 1103例患者中有640例同时进行了延长和畸形矫正，193例为身材延长病例。该设备采用了三个小的前弓与铰链撑开棒，可定制的病人解剖结构和畸形模式。此外，该装置是一个弧形铰链系统，具有不同角度和水平的销钉，以提供稳定的骨固定和承重。结果根据获得的骨长度、功能活动度、愈合时间和并发症发生率进行评估。结果：平均骨延长5.6 cm（范围2 ~ 18 cm），骨愈合时间260 d。并发症极少且可控；25例发生浅表针部感染，9例发生挛缩，1例发生深部感染。身高病例（193例）平均延长6.5 cm，功能预后良好。结论：Salamehfix 1是一种有效的、对患者友好的外固定系统，可以在各种畸形和美容病例中同时进行矫正和延长。与传统设备相比，它具有显著的机械和临床优势。

期刊介绍： International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters. Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable. The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
