Intraoperative migration of the trial femoral head into the pelvis during total hip arthroplasty: prevention and retrieval

Transperitoneal laparoscopic retrievement of a migrated prosthetic head after total hip arthroplasty: a case report

The migration of a prosthetic head during total hip arthroplasty (THA) is a rare complication. Few cases are described in the literature, offering different solutions and surgical approaches for prosthetic head retrievement. Here, we present a case of successful laparoscopic transperitoneal retrieval of a prosthetic head migrated above the right iliac vein after THA with a posterolateral approach.

Intraoperative femoral head dislodgement during total hip arthroplasty: a report of four cases

Dislodgment of trial femoral heads and migration into the pelvis during total hip arthroplasty is a rarely reported complication with limited published cases. There are three primary mechanisms of femoral head separation: dislodgement during reduction attempt, disassociation from anterior dislocation while assessing anterior stability, and during dislocation after implant trialing. If the trial femoral migrates beyond the pelvic brim, it is safer to finish the total hip arthroplasty and address the retained object after repositioning or in a planned second procedure with a general surgeon. We recommend operative retrieval since long-term complications from retention or clinical results are lacking.

Intra-pelvic migration of femoral head trial in total hip arthroplasty, a rare intra-operative complication: a systematic literature review

Trial reduction while performing total hip replacement is an essential step of the procedure. This is to check the stability of the hip joint with the selected implant sizes and to assess the leg length to avoid discrepancy. Disengagement of the femoral head trial from the femoral rasp stem with subsequent migration of the trial head into the pelvic cavity is a rare occurrence, but can be a very frustrating complication to both the surgeon and occasionally the patient. We present our experience with this exceptional situation and different management options, together with systematic review of the literature.

Dislocated trial femoral head during total hip arthroplasty: review of the literature and the new algorithm for treatment

Dislocation of the trial femoral head is a rare and unpleasant event that can compromise the success of the total hip arthroplasty. A 62-year-old Caucasian woman with osteoarthritis was admitted to our Department and underwent an elective total hip arthroplasty. While performing the dislocation manoeuver the trial femoral head dissociated from the taper in the superior and anterior direction in the soft tissue and could not be retrieved immediately. The operation was then executed and finished in an ordinary manner. Three months after discharge from our department patient presented with the pain in the hip and groin and periprosthetic joint infection was diagnosed. The successful second operation for the retrieval of the dislocated trial femoral head was conducted through ilioinguinal approach. In this paper we reviewed the published literature and developed the algorithm for the decision-making while dealing with the dislocated and lost trial femoral head.

Intrapelvic dislocation of a femoral trial head during primary total hip arthroplasty requiring laparotomy for retrieval

Background and Purpose:

Total hip arthroplasty (THA) is a safe and reliable surgical procedure. However, THA also has intra- and postoperative complications. A dreaded and frustrating intraoperative complication during total hip arthroplasty is dislocation of the femoral trial head from the neck into the pelvis.

Methods:

Here, we report on the case of a 71-year old female patient with osteoarthritis of the left hip. Total hip arthroplasty was performed in a lateral position through a standard posterior approach. During intraoperative trial reduction, the femoral trial head dissociated from the taper and dislocated into the psoas compartment. Several unsuccessful attempts, including an additional ventral approach, were made to immediately retrieve the femoral trial head.

Results and interpretation:

Postoperative a Computerized Tomography (CT) was performed to locate the trial head, a secondary explorative laparotomy was undertaken to retrieve it. The retrieval of the femoral trial head should be performed in a planned second surgical procedure to avoid possible complications during the manipulation necessary for retrieval.

Pitfall in total hip arthroplasty: intraoperative migration of the trial femoral head through the iliopsoas muscle

Total hip arthroplasty is actually one of the most orthopaedic procedures realised to treat a lot of conditions in hip pathology. Complications associated with this operation are well established and reported in the medical literature. Only few cases of intraoperative dislocation of the trial femoral head had been reported; we present a case of intraoperative intrapelvic dislocation of the trial femoral head through the iliopsoas muscle during total hip replacement with a standard posterolateral approach of Moore.

Process optimized minimally invasive total hip replacement

The purpose of this study was to analyse a new concept of using the the minimally invasive direct anterior approach (DAA) in total hip replacement (THR) in combination with the leg positioner (Rotex- Table) and a modified retractor system (Condor). We evaluated retrospectively the first 100 primary THR operated with the new concept between 2009 and 2010, regarding operation data, radiological and clinical outcome (HOOS). All surgeries were perfomed in a standardized operation technique including navigation. The average age of the patients was 68 years (37 to 92 years), with a mean BMI of 26.5 (17 to 43). The mean time of surgery was 80 min. (55 to 130 min). The blood loss showed an average of 511.5 mL (200 to 1000 mL). No intra-operative complications occurred. The postoperative complication rate was 6%. The HOOS increased from 43 points pre-operatively to 90 (max 100 points) 3 months after surgery. The radiological analysis showed an average cup inclination of 43° and a leg length discrepancy in a range of +/− 5 mm in 99%. The presented technique led to excellent clinic results, showed low complication rates and allowed correct implant positions although manpower was saved.
