Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

There is some debate over the best treatment for anterior-superior iliac spine (ASIS) avulsion fractures although conservative treatment can be applied when there are no neurological symptoms. Open reduction and internal fixation can be performed for dislocations exceeding 1.5 cm, or in patients requiring a short period of convalescence, although a second operation is subsequently required to extract osteosynthetic material. In this paper, we introduce the use of absorbable screws as a new fixation material for the second round of surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To investigate the feasibility of absorbable screws as a new fixation material for the treatment of ASIS avulsion fractures in children and adolescents.The investigator plan to retrospectively analyzed 59 patients diagnosed with ASIS avulsion fractures in our hospital between Jan 2009 and Dec 2016. These patients were divided into two groups: group A (conservative group) and group B (absorbable screws). Group A received conservative therapy involving bed rest with the affected lower extremity positioned with the hip and knee in flexion to ensure minimal tension of the muscles attached to the ASIS avulsion fracture. Group B received open reduction and internal fixation with fixation by absorbable screws. Six weeks and three months after treatment, all patients were assessed for range of motion (ROM) and by X-ray as they returned to activity. One week after treatment, the American Academy of Orthopaedic Surgeons (AAOS) lower limb and hip score was used to evaluate hip function; the same scores were also determined during follow-up at 1, 3, 6 and 12 months postoperatively.
