Introduction: Complex fracture of the acetabulum are difficult to treat. If an osteosynthesis is performed difficult surgery resulted in blood loss, long operating time, high risk of sepsis and failure. Even if the fracture is well operated and ideally stabilised there is a major risk of secondary osteoarthrosis. This can be related to bone necrosis , cartilage surface damage , bone loss. There are also intraoperative risks of neural damage: sciatic nerve as well as gluteus medius nerve. On the other hand , modern surgical technique including an alumina against alumina bearing could allow very long term survival without any activity limitation and this even in very young patients. Secondary procedure after a failed osteosynthesis provides statistically worse functional results than primary total hip. The surgery is more difficult because of hardware retrieval, nerve dissection, bone reconstruction and remaining muscular dysfunction.

It is widely recognised that pelvic disruption in association with high-energy trauma is a life-threatening injury. The potential morbidity and mortality associated with acetabular injuries are less well understood. Due to chronic underfunding and the absence of a comprehensive and coordinated national approach to the management of acetabular trauma throughout the UK, patients can incur prolonged recumbency. Prompt and appropriate referral for specialist management, thromboprophylaxis and venous thrombosis surveillance are important issues for the referring centre. We performed a postal questionnaire to establish the current clinical practice in the specialist centres throughout the UK in pelvic and acetabular trauma, with respect to time to surgery, thromboprophylaxis, and surveillance. We identified twenty-one units and thirty-seven surgeons in the NHS who deal with pelvic and acetabular injuries. The mean time to surgery from injury in the UK is 8.5 days (range 2-19 days). The larger units that accept and treat patients from outside their region experience the greatest delay to surgery. Mechanical thromboprophylaxis was used in 67% (14) of the units. 24% (5) use arterio-venous boots, 19% (4) use calf pumps, and 52% (11) use TEDS stockings. No unit routinely use prophylactic IVC filters in acetabular trauma. Chemical thromboprophylaxis is routinely used in 100% (21) of the units. 95% (20) used prophylactic doses of unfractionated heparin or low molecular weight heparin. Clinical surveillance alone for thromboembolism is employed in 90% (19) of the units. Only 2 (10%) units routinely perform radiological surveillance with ultrasound Doppler on its

Introduction.
We reviewed the outcome, at a mean follow-up of 14 months, of 21 two-column fractures of the acetabulum treated by operation through one or two non-extensile approaches. Eighteen procedures resulted in reduction of the articular surfaces to within 3 mm. The blood loss and operating time when two combined non-extensile approaches were used were similar to those reported for extended acetabular approaches. The incidence of heterotopic ossification which limited joint motion was low, and the average Harris hip score was 81 points. The use of non-extensile approaches for

Patients and Methods
Total hip replacement (THR) after acetabular
fracture presents unique challenges to the orthopaedic surgeon.
The majority of patients can be treated with a standard THR, resulting
in a very reasonable outcome. Technical challenges however include
infection, residual pelvic deformity, acetabular bone loss with
ununited fractures, osteonecrosis of bone fragments, retained metalwork,
heterotopic ossification, dealing with the sciatic nerve, and the
difficulties of obtaining long-term acetabular component fixation.
Indications for an acute THR include young patients with both femoral
head and acetabular involvement with severe comminution that cannot
be reconstructed, and the elderly, with severe bony comminution.
The outcomes of THR for established post-traumatic arthritis include
excellent pain relief and functional improvements. The use of modern
implants and alternative bearing surfaces should improve outcomes
further. Cite this article:
Purpose: Twenty-one total hip arthroplasties after ace-tabular fracture were reviewed at a minimum two-year follow-up. The purpose of this analysis was to study operative difficulties and complications in implanting a total hip arthroplasty on a sequelar acetabulum. Material and methods: Ten acetabula had been treated surgically and eleven orthopaedically. Mean time interval between the initial trauma and the arthroplasty was 14 years (range 2 – 36). The posteriolateral approach was used in thirteen cases and the anterolateral approach in eight. Osteosynthesis material was totally removed in two patients and partially in three. Arthrolysis was performed in one patient who had grade IV heterotopic ossifications. Most of the cups were hydroxyapatite coated uncemented cups; two cups were cemented in a Postel Kerboul ring. Results: An autologous graft was required for nine of the eleven orthopaedically treated fractures versus two of the ten surgically treated fractures (p <
0 .05). Mean operative time was 136 minutes and mean blood loss was 1200cc. Postoperative complications included one superficial phlebitis, one infraperitoneal bladder wound, one superficial haematoma, one incomplete popliteal palsy, one dislocation and two heterotopic ossiications (1 Brooker I and 1 Brooker IV). At review, the mean Postel Merle d’Aubigné score was 16.5. Radiologically there was no evidence of loosening or defective fixation. Discussion: The operative difficulty was basically encountered in the group of orthopaedically treated
Purpose: Preoperative planning forces the surgeon to understand the “fracture personality” and devise an operative plan. In our experience, trainees have difficulty in preparing for complex acetabular cases; these fractures are among the most difficult fractures to conceptualize and teach. As a result, these fractures are poorly understood as demonstrated by low interobserver agreement between trainees in the classification of

Introduction The results of THA in patients with post-traumatic arthritis are inferior to those in nontraumatic arthritis, both after cemented and noncemented THA. This increased failure rate is caused by the bone stock loss and the abnormal anatomy. We studied the outcome of acetabular bone impaction grafting and a cemented cup in 20 cases at 3 to 18 years follow-up. Materials and Methods Between January 1984 and January 2000 in 20 consecutive patients bone impaction grafting was used for arthritis after previous
Three middle-aged patients with diabetes sustained fractures of the acetabulum which were treated by open reduction and internal fixation. In each, rapid dissolution of the femoral head occurred with minimal discomfort, typical of a Charcot arthropathy. The patients had no other evidence of neuropathic arthropathy. Charcot changes may occur after high-energy trauma in patients with diabetes.
Traumatic posterior dislocation of the hip associated with a fracture of the posterior acetabular wall and of the neck of the femur is a rare injury. A 29-year-old man presented at a level 1 trauma centre with a locked posterior dislocation of the right hip, with fractures of the femoral neck and the posterior wall of the acetabulum after a bicycle accident. An attempted closed reduction had failed. This case report describes in detail the surgical management and the clinical and radiological outcome. Open reduction and fixation with preservation of the intact retinaculum was undertaken within five hours of injury with surgical dislocation of the hip and a trochanteric osteotomy. Two years after operation the function of the injured hip was good. Plain radiographs and MR scans showed early signs of osteoarthritis with some loss of joint space but no evidence of avascular necrosis. The patient had begun skiing and hiking again. The combination of fractures of the neck of the femur and of the posterior wall of the acetabulum hampers closed reduction of a posterior dislocation of the hip. Surgical dislocation of the hip with trochanteric flip osteotomy allows controlled open reduction of the fractures, with inspection of the hip joint and preservation of the vascular supply.
From 1987 to 1991, we treated 53 patients with 54 fractures of the acetabulum by reconstruction through a posterior or an extended iliofemoral surgical approach. For prophylaxis against heterotopic ossification we used perioperative irradiation and indomethacin. Indomethacin was given as daily doses of 25 mg started within 24 hours of operation and continued for four weeks. Irradiation was by either 1200 cGy in three daily doses or by a single 700 cGy dose on the first postoperative day. All patients were followed for at least one year postoperatively and the severity of heterotopic ossification was recorded using the Brooker classification and correlated with hip mobility. The combination therapy proved very effective; 44 fractures showed no heterotopic ossification and ten showed Brooker class I. The functional results were good and there were no complications of this therapy. Irradiation with 1200 cGy did not appear to offer any therapeutic advantage over the 700 cGy dose.
Using finely reconstructed helical pelvis CT scans of ninety-three cases and image analysis software, we define the “Safe Zone” for the extra-articular placement of screws during internal fixation of the acetabulum, using a Stoppa approach. Screws should be at most: 11mm from the top of the Sciatic notch, 23mm from the tip of the Ischial Spine, and at most 5mm posterior to the top of the Obturator canal, along the pelvic brim. The purpose of this study was to identify a “safe zone” in the inner pelvis, to allow extra-articular screw placement using the Stoppa approach. Acetabulum internal fixation screws can safely (extra-articular position) be placed through the Stoppa approach using three identifiable landmarks. Surgeons can use these identifiable anatomic landmarks for the safe placement of screws along the inner aspect of the acetabulum. Study Population: males:females 47%:53%, mean age: 51,3yrs (18–88). Reference measurements (means): Femoral Head (FH): 45,5mm (36–6), Inter-SI joint:177,9mm (102–34). Safe distance to joint: 1) from Sciatic notch: 11mm; 2) from Ischial Spine: 23mm; 3) from Obturator roof: 5mm. The Ischial Spine Distance (ISD) showed clustering (p<
0.05) into two groups according to Femoral Head diameter: FH<
47mm: Safe ISD=23mm ; FH≥47mm: Safe IS=28mm. Ninety-three Helical Pelvis CT scans with fine reconstruction were done between July 1, 1999-June 30, 2000. Axial images were analyzed using GE Vox Tool® v.3.0.3 image analysis software. The femoral head diameter and the Inter-SI joint distance were used as reference. The distance between three identifiable bony landmarks and the point which would allow the placement of a 4mm screw outside the hip joint were measured. Inter and Intra-observer reliability study showed a difference <
1mm in >
90% of cases. Surgical approaches which avoid extensive dissection and manipulation of the gluteal musculature are gaining in popularity. The Stoppa is such an approach which gives access to the medial acetabular wall and to the inner pelvis from the SI joint to the symphysis along the pelvic brim. This blind approach does not allow visualisation of the joint and confirmation of screw placement. The present paper offers surgeons these reference points.
The optimal positioning of the acetabular component is a relevant prognostic factor in total hip arthroplasty (THA). Because of substantial errors of manual technique in cup placement even with experienced surgeon, computer aided navigation system has been developed in recent years. However, existence of the hardware around acetabulum likely deteriorates the accuracy of the navigation system, namely in revision THA case and postoperative status of pelvic fracture. Here we report a case who we successfully performed THA using CT based navigation system although there were multiple hardware around acetabulum due to osteosynthesis for the previous pelvic fracture. A forty-one years old man presented with intolerable hip pain with severe radiographic osteoarthritic findings in left hip joint. He had sustained left pelvic fracture and posterior hip dislocation due to traffic accident and undergone osteosynthesis using multiple plates and screws when he was forty years old. However, progressive collapsing of femoral head and acetabulum occurred. Then, we indicated THA for his situation and planned to apply the CT based navigation system (Stryker CT based hip Ver.1.1 softwear and Cart II system). Preoperative workup revealed incomplete union of posterior and superior acetabular wall and we had to retain plates and screws for the stable fixation of acetabular cup. The existence of the hardware made it complicated to perform three dimensional planning and templating. Meticulous surface editing of pelvis to exclude the metal artifact and fibrocartilagenous tissue was needed to achieve accurate surface registration. In the operation room, we had to use unusual way of registration to complete two steps of registration. In the first step (roughly matching between patient's physical pelvic surface and edited pelvic surface in work station using corresponding 5 points), we utilized head of screw and hole of the plate which we could easily identify intraoperatively, in addition to ASIS and innominate groove. In the second step (strict matching using more than 30 points of pelvic surface), we had to identify the pelvic bony surface, as excluding the metal surface and fibrocartilagenous tissue such as fracture callus. These efforts enabled us to accomplish substantial accuracy of registration with RMS of 0.5 mm. Final cup orientation at the end of surgery was 41° of inclination and 25° of anteversion. Postoperative CT scan revealed that cup placement angle was 40° of inclination and 25° of anteversion, almost identical with intraoperative value.Objective

Intraoperative fractures although rare are one of the complications known to occur while performing a total hip arthroplasty (THA). However, due to lower incidence rates there is currently a gap in this area of literature that systematically reviews this important issue of complications associated with THA. Method: We looked into Electronic databases including PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), the archives of meetings of orthopaedic associations and the bibliographies of included articles and asked experts to identify prospective studies, published in any language that evaluated intra-operative fractures occurring during total hip arthroplasty from the year 1950-2020. The screening, data extraction and quality assessment were carried out by two researchers and if there was any discrepancy, a third reviewer was involved. Fourteen studies were identified. The reported range of occurrence of fracture while performing hip replacement surgery was found to be 0.4-7.6%. Major risk factors identified were surgical approaches, Elderly age, less Metaphyseal-Diaphyseal Index score, change in resistance while insertion of the femur implants, inexperienced surgeons, uncemented femoral components, use of monoblock elliptical components, implantation of the acetabular components, patients with ankylosing spondylitis, female gender, uncemented stems in patients with abnormal proximal femoral anatomy and with cortices, different stem designs, heterogeneous fracture patterns and toothed design. Intraoperative fractures during THA were managed with cerclage wire, femoral revision, intramedullary nail and cerclage wires, use of internal fixation plates and screws for management of intra operative femur and
