Case Study
Objective: To report the clinical application of domestic external fixator in the treatment of patients with limb deformities and investigate the application effect. Methods: Retrospective analysis of the clinical data of patients with limbs deformities from Qin Sihe Department of Orthopedic Surgery from January 1989 to June 2016. Demonstration of the cases with using the domestic bone external fixator for deformity correction and analyzing the data about gender, age, type of external fixator, surgical side, the number, diseases and results of application. Results: The total number of 7289 patients were treated with the domestic external fixator, including 4033 males and 3256 females, with the mean age of 23.4 years (ranging from 2 to 82 years). Type of external fixator: Ilizarov external fixator (2732), hybrid external fixator (4713), monobrachial external fixator (57). Operative site: Ilizarov, hybrid and monobrachial external fixators used in the upper limbs were 67, 65 and 0, respectively; in the lower limbs were 2665, 4616 and 57, respectively. Surgical side: the left limbs – 3028, the right limbs – 3260, the bilateral limbs – 1001. Types of diseases: The top three are the sequelae of poliomyelitis, cerebral palsy and PTSD peromely. Deformity types included talipes equinovarus, Knee Flexion deformity, pes cavus and so on. 7289 patients were followed up for a period of 2.5 months to 22.4 years, with an average follow-up time of 5.4 years. All of the external fixators were used for single once, and there was no substitute for external fixator quality problem. Except 1 case giving up treatment to remove the fixator and another one for metal allergy, the rest of the patients were completed surgery goal with removing external fixation. The common complications included pin infection and joint movement limitation and so on. Conclusions: The domestic external fixator development and production combined with the characteristics of Chinese limb deformity disability are able to treat kinds of limb deformities. It has the advantages of being practical, economical, adjustable, universal, portable and so on, and can meet the clinical demand of the fixation of osteotomy end of the limbs, the correction of the deformity, the repair of the defects and the limb lengthening and so on.

    Ulnar longitudinal deficiency (ULD) is a rare condition of the upper limbs. Although radius lengthening for radial longitudinal deficiencies (RLD) was found to be successful, no ulnar lengthening for ULD without RLD and hand deformities has been reported. Herein, we present a Bayne type II ULD...

    Background: Distal femoral osteotomies (DFO) can be used to correct deformities around the knee. Although osteotomies can be fixed with either internal or external fixation techniques, the advantages of one over the other are unclear. Questions/purposes: We asked whether (1) for both techniques,...
