Constant score was significantly improved with GT, LT and both tuberosity healing (p = 0.05, p = 0.04 and p = 0.02 respectively). RESULTS: The GT healed in 22 patients (78.5%), the LT in 24 patients (87.5%) and both tuberosities were healed in 20 patients (71.5%). Clinical examination and CT scan were performed at a minimum one year follow-up to assess tuberosity position and healing. METHODS: Our retrospective cohort consisted of 28 patients treated with an RSA for a four-part PHF during the inclusion period. Our hypothesis was that both GT and LT healing leads to better functional results after RSA for fracture.

The aim of this study was to assess greater and lesser tuberosity (LT) fixation and healing on CT scan after RSA for PHF. The rate of greater tuberosity (GT) healing varies from 37 to 90% in this population.

The patients in the "moderate improvement" group were significantly older (37 years☘ FEAR index was significantly higher and the AWI and VCE were significantly lower in the "failure" group. The "success" group consisted of 21 patients (56%, 21/39), the "moderate improvement" group of 12 patients (31%, 12/39) and the failure group of 6 patients (13%, 6/39) (2 subsequently underwent total hip replacement, 4 underwent shelf acetabuloplasty). The area under the curve (AUC) for the most relevant data identified during the univariate analysis were then modeled to define which factors were the best at predicting failed arthroscopic treatment a posteriori. Demographic data, radiographic parameters (LCEA, Tönnis angle, alpha angle, offset, FEAR index, Shenton's line, Cliff sign, anterior wall index, posterior wall index ) and intraoperative findings were compared between these three groups. Three groups were defined based on the outcomes: success (mHHS ≥ Patient Acceptable Symptomatic State ) moderate improvement (improvement in mHHS + mHHS mermoz lyon hopital

Few studies have investigated which radiological parameters are associated with failure of this procedure.Ī larger number of radiological signs of mild or borderline hip dysplasia than radiological signs of FAI negatively influence the outcomes of arthroscopic treatment.

It is recommended to combine capsular plication with femoral neck osteoplasty and suture repair of the labrum. The role of arthroscopic treatment of femoroacetabular impingement (FAI) in mild or borderline hip dysplasia (lateral center edge angle=18-25) is controversial.
