Whatley, MD Baton Rouge Orthopaedic Clinic, Baton Rouge, LA, USA Chapter Introduction and Scope of the Problem Andrew H. Schmidt Acetabular fractures in the elderly population are increasing in frequency, with the incidence of such fractures in patients over age 60 more than doubling in the past 25 years [1] In younger patients, such fractures result from high-energy trauma In older patients, acetabular fractures are just as likely to occur from low energy as a high-energy mechanism [1, 2] Acetabular fractures that result from low-energy trauma (typically a fall from standing height) are associated with osteopenia and are considered a marker of significant frailty, and such patients tend to be older, have a lower body mass index, and have more comorbidities than patients with acetabular fractures from higher-energy trauma [2] As might be expected given the differences in patient’s bone density and mechanisms of injury, acetabular fractures in the elderly have different fracture patterns than are seen in younger population, with a greater incidence of anterior column impaction, involvement of the quadrilateral plate, and articular impaction (Fig. 1.1) [3] Like patients with fractures of the proximal femur, elderly patients who suffer an acetabular fracture have significant mortality, reported to be as high as 25% [4] However, unlike proximal femur fractures, surgical repair of acetabular fractures in the elderly has not been shown to reduce mortality [5] Management of elderly patients with acetabular fracture is challenging As with all elderly patients with “hip” fractures, these patients demand and benefit from expert multidisciplinary co-management including input from geriatrics, internal medicine, orthopedic surgery, anesthesiology, and occasionally other medical and surgical subspecialties Nonoperative management of these injuries results in unacceptable outcomes in 30% or more of patients [6] Internal fixation of these complex fractures in patients with reduced bone quality and inability to “protect” the hip from loading following surgery make open reduction and internal fixation (ORIF) A H Schmidt (*) Hennepin Healthcare, Minneapolis, MN, USA University of Minnesota, Minneapolis, MN, USA e-mail: schmi115@umn.edu © Springer Nature Switzerland AG 2020 T T

screw We were concerned that this would interfere with acetabular component placement so it was removed through exposure of the pelvic brim A direct anterior approach to the hip was used In this case release of the inguinal ligament was not necessary and a 4 cm incision over the iliac crest with subperiosteal dissection underneath the iliacus was all that was required to remove the long cannulated screw (and a portion of the pelvic brim plate) prior to total hip arthroplasty (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) and screws can be easily removed in the case of acetabular component impingement or suspicion of infection This is particularly true if the plates and screws are more laterally positioned on the acetabulum (Figs. 11.15, 11.16, and 11.17) Posterior Approach for Conversion to a Total Hip Replacement The patient is positioned in a lateral decubitus position taking care to position the pelvis as orthogonal to the table as possible and to have the lumbar spine parallel to the back edge of the operating room table The leg is prepped free, but in our center no neural monitoring is used during the procedure A standard posterior approach to the hip is used with a couple of important caveats (Fig. 11.18) First on approach and exposure, five sets of deep tissue cultures are taken and frozen section specimens are taken on each case Although the literature guiding the interpretation of frozen sections in these cases is inconclusive, if we see more than 5–10 white blood cells in multiple high-powered fields present in the frozen section analysis, we would proceed with fracture implant removal, Prostalac spacer implantation, and later staged hip replacement Another difference from a standard posterior approach to the hip is that in each case we release the gluteus maximus sling tagging it for later repair (Figs. 11.19 and 11.20) This is to take pressure off the sciatic nerve when the hip is internally rotated We not formally dissect the tissues around the sciatic nerve unless there is a preoperative sciatic nerve palsy If there is a preoperative sciatic nerve palsy, then we 11 Conversion Total Hip Arthroplasty 155 Fig 11.16 This patient has posttraumatic osteoarthritis with two spring plates in place Even if these plates and screws would end up impinging on the acetabular component, they can be easily bent away from the final acetabular component with an osteotome It is perfectly acceptable to use a direct anterior or Hardinge approach to the hip for these patients (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) will free up a lateral scar tissue on the sciatic nerve and trace the nerve up to the sciatic notch However, we will not perform circumferential dissection of the nerve in most cases The external rotators and capsule are released from the posterior greater trochanter as one unit, as they are often indistinguishable based on the scarring present Heterotopic bone that is present is removed at this time period with 0.75 inch curved osteotome Preparation of the Acetabulum: The “Inside-Out” Technique If the implants from the posterior wall and column need to be removed, then we use a specific technique for removal We start inside the acetabulum and we use a Bovie to elevate the capsule off the posterior wall and column We this with a hip extended, with the knee flexed, and with a hand on the foot, so that if the Bovie gets to close the sciatic nerve, the anterior tibialis or extensor hallucis longus will fire The capsule is then elevated “inside-out” technique staying strictly subperiosteal as 156 T T Manson and A J Johnson Fig 11.17 In this patient with posttraumatic osteoarthritis, marked heterotopic ossification, and more laterally based 3.5 mm reconstruction plates, the potential for these implants to interfere with acetabular component placement is much higher In this case, we would recommend using a Kocher-Langenbeck approach to the hip so that these implants could be removed if necessary (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) Fig 11.18 The previous Kocher-Langenbeck approach to the hip is used However it is usually not necessary to utilize the entire incision that was used for acetabular fixation (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) 11 Conversion Total Hip Arthroplasty 157 Fig 11.19 The gluteus maximus sling is exposed and released by placing a tonsil clamp medial to the sling and then releasing the sling using Bovie electrocautery In this image the patients head is to the left of the image (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) Fig 11.20 Care must be used as there are often times large blood vessels directly applied to the medial aspect of the gluteus maximus sling and sometimes this sciatic nerve can be scarred up against the medial aspect of the sling as well The majority of the sling is released and then marked for repair at the conclusion of the procedure (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) far medially and posteriorly as is needed to access the implants in question Many times the implants are grown over with bone and this bone is most easily removed using three-quarter inch curved osteotome The “inside-out” technique proceeds from known anatomy to unknown scarred anatomy in a stepwise fashion to avoid sciatic nerve injury A 0.75 inch osteotome is used to peel away scar tissue and heterotopic bone starting inside the acetabulum and then proceeding along the superior rim of the acetabulum (Figs. 11.21 and 11.22] Then with the superior aspect of the acetabulum and fixation plate exposed, the osteotome is directed inferiorly and medially to dissect along the posterior wall toward the sciatic notch and ischium (Figs. 11.22 and 11.23) This is clinically shown in (Figs. 11.24, 11.25, 11.26, and 11.27) It is extremely important that the hip is kept extended and the knee bent during exposure to minimize pressure on the sciatic nerve as has been described by Dr Letournel [7] Then after the plate is exposed, the screw heads are freed of heterotopic bone and fibrous tissue and removed under direct vision (Figs. 11.28, 11.29, 11.30, and 11.31) 158 T T Manson and A J Johnson Fig 11.21 Shows progression of the exposure of the posterior acetabulum We start with a three-quarter inch curved sharp osteotome inside the acetabulum (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) Fig 11.22 We then extend the osteotome dissection up over this superior lateral aspect of the acetabulum first so that we get a subperiosteal dissection of the posterior acetabulum (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) Usually, only the implants that are going to directly interfere with acetabular component placement are removed Many times posterior wall fixation implants may interfere with acetabular placement but the more medial posterior column fixation can be retained (Fig. 11.32) The basis of all acetabular preparation is to a wedge acetabular component in between the ischium and the anterior inferior iliac spine as detailed in (Fig. 8.6) Many times there will be large posterior wall defects that not affect component fixation unless the ischium or AIIS is compromised For acetabular preparation, we start reaming to the base of the cotyloid fossa and then use sequentially larger reamers to ream for a 1 mm press-fit in the acetabulum 11 Conversion Total Hip Arthroplasty 159 Fig 11.23 shows further dissection using a three-quarter inch curved osteotome along the posterior acetabulum heading toward greater sciatic notch It is critical during this portion of the procedure that the hip is extended and the knee is flexed to take pressure off of the sciatic nerve In addition Bovie electrocautery rather than a knife will allow recognition of proximity to the sciatic nerve as the foot will jump if the Bovie gets near to the nerve (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) Fig 11.24 shows the most difficult part of the exposure where the posterior lateral aspect of the acetabulum stretching down to the hamstring insertion is exposed to remove the most distal screws present in an acetabular reconstruction plate Careful dissection making sure to stay subperiosteal and noting any twitches of the foot will help protect the sciatic nerve (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) 160 T T Manson and A J Johnson Fig 11.25 Shows a intraoperative photos of the retained reconstruction plate that we want to remove The patients head is to the left of the picture and the foot is to the right A retractor holds the femur anteriorly while we expose the posterior plate and screws (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) Fig 11.26 shows the three-quarter inch osteotome clearing heterotopic bone which incarcerates the plate heading directly superiorly in the 11 o’clock position on the acetabulum (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) Screws and plates that impinge on the acetabular reamers are removed Through this approach, the screws were usually removed in their entirety using a screwdriver However, a high-speed burr could be used for removal of screw segments if the surgeon felt this is necessary We usually prefer to remove the screws entirely and not use the burr to minimize metal fragment generation A standard multihole acetabular high porous coated revision component is used We use the transverse acetabular ligament as well as fluoroscopic imaging to guide 11 Conversion Total Hip Arthroplasty 161 Fig 11.27 shows the three-quarter inch curved osteotome being used to free the posterior capsule and heterotopic bone from the plate and screws Care is taken at this point to again flex the knee and extend the hip to protect the sciatic nerve (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) Fig 11.28 shows gentle exposure of the most distal aspect of the posterior reconstruction plate and ischium Often times gentle taps on the osteotome will allow for a subperiosteal dissection with minimal soft tissue disruption (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) component placement However, the surgeon should be cautioned that the transverse acetabular ligament will not be in the normal location to the acetabular deformity If the acetabular bone defects are large, then multiple screws superior and inferior to the equator of the acetabular component should be used to optimize initial fixation and allow early weight-bearing (Figs. 11.33 and 11.34) 162 T T Manson and A J Johnson Fig 11.29 shows screws being removed from the proximal aspect of the reconstruction plate (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) Fig 11.30 show screws being removed from the distal aspect of the reconstruction plate These distal screws can often have stripped heads due to their angle of insertion and so care is taken to visualize the screwdriver entering the head of the screw prior to screw extraction (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) A careful repair of the external rotators and capsule to the trailing edge of the gluteus medius tendon or through drill holes in the posterior greater trochanter is utilized to limit postoperative dislocation [8, 9] Postoperative Care In many cases the acetabular stability obtained by this technique is excellent and patients can begin full weight-bearing immediately after surgery If there are concerns, the surgeon can keep the patient 50% weight-bearing for four to six weeks 11 Conversion Total Hip Arthroplasty 163 Figs 11.31 and 11.32 to show removal of the reconstruction plate after it has been freed from its screws (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) Fig 11.33 shows a typical patient with posttraumatic left hip osteoarthritis that was treated with conversion through a Kocher approach The posterior column plate did not impinge with implant placement and so was left in place The posterior wall reconstruction plate was removed as it was found to impinge on the acetabular reamer during preparation for an acetabular component (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) after surgery, but usually is the maximum amount of time that the patient would need to be protected weight-bearing and gradual languishment of assistive devices is encouraged Patients are followed very closely for graft consolidation and usually this is reliable given the autograft femoral head that is utilized 164 T T Manson and A J Johnson Fig 11.34 shows a patient who had difficulty with wound healing around the time of her initial fracture fixation A preoperative aspiration, CRP, and ESR were all negative However in these cases an abundance of caution is prudent At the time of conversion hip replacement, we removed all of her implants and treated her with a one-stage exchange to a primary hip replacement As noted, we did use a multihole acetabular component with screws both superior and inferior to the equator of the cup to optimize her acetabular component stability and allow early weight-bearing (Property of Theodore Manson and the R Adams Cowley Shock Trauma Center Used with Permission) References Ibrahim MS, Raja S, Haddad FS.
