Peer Review Report
Peer review report 1 on “Intraoperative Dislocation of the Trial Bipolar Cup into the Pelvis during Bipolar Hip Arthroplasty” [H1]Original Submission [H2]Recommendation
5. The terminology is confusing and does not give the reader the clear message that dislocation of the component was initially outside the hip and outside the pelvis, only to then become intra-pelvic, before its ultimate successful removal.
Major Revision I suggest the message needs to be clarified, in pointing out that: [H2]Comments to the author This is an important report however there are a number of important points that need to be amended to make the paper highlight the message you wish to put across to the readers. 1. You describe the dislocation as being into the anterior joint space. This is incorrect and suggests an inadequate knowledge of anatomy of the hip joint and its surrounding areas. The initial dislocation was into the extra-articular space (completely outside the joint space) and it was from there that your numerous attempts to retrieve it failed. 2. You must accept that these attempts pushed the component deep to the psoas muscle from where it migrated into the pelvis, and indeed from where you ultimately retrieved it. 3. You need to accept that your attempts to remove the migrated component from anterior to the hip joint resulted in it being forced into the pelvis from where it was subsequently removed. 4. You have not made it clear from where exactly you ultimately removed the component.

1. Dislocation of the head or cup is not as infrequent as one thinks but in most cases it is easily retrieved and removed before completing the operation, 2. Attempting to retrieve the component may result in further displacement and even push the component into the pelvis. This is a very important part of the message in this report and has not been made. This point is not made and failure to make it is to fail to learn from the problems you encountered and a failure to try and ensure that others who read your report will learn this important message. 3. Should the component end up in the pelvis, the recommended approach is to remove it, at a time and through an approach that is appropriate to the individual patient and circumstances.
