“…The Hill-Sachs lesion is associated with shoulder instability and recurrent dislocations [6,7,24], which affect shoulder function and even the outcome after arthroscopic Bankart repairs [8]. If the lesion occupies a specific size and position on the humeral head, shoulder destabilisation occurs [25][26][27].…”

Purpose Traumatic shoulder dislocation may be complicated by concomitant bony injury of the glenoid rim or the humeral head. In Hill-Sachs lesions, reconstruction techniques vary widely and range from open reduction to tendon transposition or humeral head derotation. These operations are extensive and have questionable outcomes. With the expertise from vertebral compression fracture reduction by kyphoplasty, we examined in a cadaver feasibility study whether reduction of the Hill-Sachs lesion via hydraulic lift might be an anatomical and minimally invasive treatment option. We postulated that the use a of a balloon-assisted kyphoplasty reduction could achieve almost anatomical correction of the defect. Methods We created Hill-Sachs lesions in six humeral specimens and performed a computed tomography (CT) scan before and after reduction with the kyphoplasty system. The entry point at the greater tuberosity and balloon positioning was visualised by fluoroscopy. The size of the HillSachs lesion before and after reduction was measured using CT scans in the axial orientation. Results Using the balloon kyphoplasty system, we achieved a statistically significant reduction (80 % ) of the Hill-Sachs lesion. Conclusion In a preliminary cadaver study we show that using a balloon kyphoplasty system might be an alternative treatment option for Hill-Sachs lesions, with reduced collateral damage that can occur with other minimally invasive techniques. Future work is needed to evaluate the technique under arthroscopic conditions.

“…The construction hammer was positioned at anatomical landmark of the Hill-Sachs lesion. The Lesion location was defined by Saito et al 16 They found that the average location of a right Hill-Sachs lesion is about 7:58 o'clock on a clock face where 12 o'clock is the bicipital groove or 239 from the bicipital groove.…”

“…2,3,8,10,16 This grooved humeral head defect was first described by Hill and Sachs in 1940 and reported in 74% of recurrent shoulder dislocations. 6 The location of this defect and its relation to bare area was more closely defined by Saito et al using a CT scan.…”

“…6 The location of this defect and its relation to bare area was more closely defined by Saito et al using a CT scan. 16 In vitro, this lesion is created when the soft posterolateral humeral head impacts the hard glenoid rim. Although post-traumatic shoulder instability can be successfully addressed via arthroscopic or open Bankart procedure, Burkhart and DeBeer 2 showed that 14/21 (67%) of patients with significant bony defects such as ''inverted-pear'' glenoid and engaging Hill-Sachs lesions after Bankart repair have continued instability versus 7/173 patients without such defect.…”

Location of the Hill-Sachs lesion in shoulders with recurrent anterior dislocation

Abstract: From these data, we concluded that the Hill-Sachs lesion exists in the area between 0 and 24 mm from the top of the humeral head, and the inferior portion of the Hill-Sachs lesion overlaps the bare area if it extends beyond 19 mm from the top of the humeral head.
