  • Purpose : This study was performed to evaluate the presence and severity of Hill-Sachs (HS) lesions on MR arthrography (MRA) of shoulder in patients with Bankart lesions following anterior dislocation and to investigate their relationship with Bankart lesions and frequency of dislocations. Materials and Methods: 86 MRA of shoulder were evaluated in patients with arthroscopic Bankart repairs following anterior dislocations. The largest surface length of HS lesion on MRA and extent of Bankart lesions on arthroscopy were measured. Relationships between length of HS lesions and extent of Bankart lesions and frequency of dislocations were assessed. Results: HS lesions were identified on MRA in 78 patients. The largest surface length of HS lesion ranged from 9.3 mm to 29.6 mm (mean, 18.8 mm). The extent of Bankart lesion ranged from one to six o'clock extent (mean, 4.25 o'clock extent). Three patients had single dislocation and the other 75 patients had recurrent dislocations (mean 24.5 times). The largest surface length of HS lesions was positively correlated with extent of Bankart lesions (p = 0.001, r = 0.37), but not with frequency of dislocation. Conclusion: HS lesion was very common in patients with Bankart lesion. The severity of HS lesions was correlated with extent of Bankart lesions.

  • Purpose: To assess the usefulness of early stabilization for initial shoulder dislocation which is indicated in some patients by comparing the arthroscopic findings and the outcomes of Bankart repair in the initial and recurrent dislocation. Materials and Methods: The study was performed on 16 cases of initial dislocation and 44 cases of recurrent dislocation. The follow-up period was 25 months in the initial dislocation group and 28 months in the recurrent group. Bankart lesion and the adjacent tissues were compared, and the results were evaluated by the Rowe rating scale. Results: Detached labrum and capsular ligament of the initial dislocation group were elastic and unretracted. While in the recurrent dislocation those were inelastic, and displaced and adhesive in many cases. The outcomes were mean 95 points in the initial group and 91 points in the recurrent group. In the initial group, apprehension was detected in only 1 case(6%). In the recurrent group, instability was detected in 4 cases(9%). Conclusion: Our data suggest that Bankart lesion in the initial dislocation can be repaired readily by surgery, the recovery is efficient, and the recurrence would be reduced. Thus, in active young sports lovers as well as athletes, early stabilization surgery for initial shoulder dislocation may be more helpful.

  • We report an isolated anterior dislocation of the radial head in a 23-year-old man after a fall on the outstretched arm. At the time of the injury, the patient's elbow was in a position of mild flexion and pronation which was suddenly further pronated as he fell down. The radial head was incarcerated by the lateral portion of brachialis muscle, and annular ligament was interposed between capitellum and radial head. Open reduction was performed. During 12 months follow-up, reduction of radial head was well maintained without a limitation of range of motion.
