Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients undergo a simplified open repair using a limited transversal, or submammary incision in female patients. The mobilization of pectoralis muscles and rectus abdominis are just sufficient to expose the enlarged cartilages, which are resected subperichondrially (generally total bilateral cartilage resection from 3th to the 6th, limited to the extremities of the 7th cartilages). An optional transverse anterior osteotomy of the upper sternum, followed by elevation of the distal sternum is then performed. Approximative duration is 90 min. Sternal stabilization is achieved by using an easily removable metallic strut, which is removed under local anesthesia on an outpatient basis, 6 months after the initial procedure.

Outcomes
Primary outcome [1] 258971 0
Maximal exercise performance is determined using an incremental exercise test performed on a calibrated electromagnetically braked cycle ergometer. Continuous measurement of inspired and expired oxygen and carbon dioxide output are done using in-line sensors together with spirometry. These parameters are then used to the calculation of VO2 (oxygen uptake)
Timepoint [1] 258971 0
before and one year after surgery
Secondary outcome [1] 265157 0
Oxygen pulse at maximal exercise is determined as the ratio of VO2 to heart rate

before and one year after surgery

Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients are referred for evaluation to the surgical unit at Calmette Hospital, a tertiary care hospital affiliated with Lille University School of Medicine. Patients undergo evaluation which consisted of collection of data sets (repeated echocardiography, pulmonary function and exercise testing and chest computerized tomography (CT)-scan before and after surgery. After institutional review board approval and according to their consent, patients are then proposed to surgical repair.
