Abstract
Objective: The aim of this study was to evaluate the results of 2-stage treatment of upper and lower extremity deformities in patients with thrombocytopenia absent radius syndrome.
Methods: Four patients (3 female, 1 male) with a mean age of 1.8 years (range 1-4) were included in the study. The patients were followed up for an average of 5.5 years. All 4 patients had bilateral radial longitudinal deficiency, whereas only 2 patients had bilateral fixed knee contractures. A 2-stage surgical procedure was implemented. The surgical procedure performed for radial longitudinal deficiency consisted of distraction with an Ilizarov frame in the first stage, followed by centralization performed in the second stage. Knee contractures were first treated using an Ilizarov frame, followed by a hamstring tendon transfer in the second procedure. Radiological evaluation of the radial longitudinal deficiency was done by measuring hand-forearm angle, hand-forearm position, and ulnar bowing preoperatively and at postoperative follow-ups. Knee contracture was evaluated by measuring the angle preoperatively and at postoperative follow-ups.
Results: The mean hand-forearm angle values of patients at preoperative assessment, early postoperative period, and at the last follow-ups were 82.60, 5,80, and 11.10, respectively (P < .001). The hand-forearm position values were -14.25 mm, +11, and +7.1 mm, respectively (P < .001). The ulnar bowing values were 7.3°, 4.5°, and 2.9°, respectively (P < .001). Recurrence of the radial longitudinal deficiency deformity requiring surgery occurred in 1 patient. In the other 3 patients, some deformity recurred but did not require surgical intervention. In addition, 1 patient with knee flexion contracture had a recurrence of the contracture that did not require surgical intervention. There was no circulatory disorder or skin necrosis in the lower or upper extremities of the patients.
Conclusion: This study has shown us that two-stage treatment is a reliable method for lower and upper extremity deformities accompanying thrombocytopenia absent radius syndrome. However, recurrence is still a major problem.
期刊介绍：
Acta Orthopaedica et Traumatologica Turcica (AOTT) is an international, scientific, open access periodical published in accordance with independent, unbiased, and double-blinded peer-review principles. The journal is the official publication of the Turkish Association of Orthopaedics and Traumatology, and Turkish Society of Orthopaedics and Traumatology. It is published bimonthly in January, March, May, July, September, and November. The publication language of the journal is English.
The aim of the journal is to publish original studies of the highest scientific and clinical value in orthopedics, traumatology, and related disciplines. The scope of the journal includes but not limited to diagnostic, treatment, and prevention methods related to orthopedics and traumatology. Acta Orthopaedica et Traumatologica Turcica publishes clinical and basic research articles, case reports, personal clinical and technical notes, systematic reviews and meta-analyses and letters to the Editor. Proceedings of scientific meetings are also considered for publication.
The target audience of the journal includes healthcare professionals, physicians, and researchers who are interested or working in orthopedics and traumatology field, and related disciplines.
