Assessment of clinical results after arthroscopic bony bankart repair using Sugaya technique after 7 years of experience, in patients with less than 20% of the glenoid affected, and a correlation between the size and location of the defect with the clinical outcome.


The purpose was to asses the functional outcomes after surgery using Sugaya method in acute bony bankart lesions affecting <20% of the glenoid surface; Secondary, was to assess the correlation between size and location of the osseous fragment, with postoperative stability of the glenohumeral joint using rowe and constant scores.


We did a retrospective study between March 2009 and February 2017. We included a total of 21 patients (all men, average age, 37 years; range, 24-63 years) with acute bony Bankart lesions, affecting less than <20% of the glenoid, that were treated with Sugaya technique.
The average follow-up period was 32.5 months (24.3-72 months). Postoperative range of motion was assessed with Constant, and Rowe scores to evaluate the results of surgery.
The fragment location was assessed with MRI and confirmed arthroscopically. The size of the fragment was measured by MRI using the ‘Pico–like’ method.


The mean postoperative Rowe score was 97.5 ranging from 75-100, and the mean constant score was 88.7, oscillating from 77 to 100. After surgery, 1 patient (6.25%) experienced traumatic redislocation.
The extent of the glenoid defect between varied between 8%-17% with a mean of 12,25%. We did not find a statistical significant correlation when compared to constant score using spearman correlation test (r=0.05), and showed a weak positive correlation of (r)=0.52 when using Rowe score.
The defects were located between 02:00 and 6:32, with the range between 2:50 and 5:20 being the most frequent. The mean orientation of the defect was pointing toward 3:58. We did not find a statistical significant correlation between de glenoid defect location and the Rowe or Constant scores (r=-0,3)


Arthroscopic reduction, and internal fixation of bony Bankart lesions with Sugaya technique is a good method to achieve good to excellent results in acute lesions involving <20% of the glenoid surface. For this patients we did not find a correlation of the postsurgical stability with the percentage of glenoid affected, or the location of the defect.
