Total hip replacements following acetabular fractures. 7 to 15 years clinical and radiological results

This study is reporting the long term clinical and radiographic results of a group of 45 patients who underwent total hip arthroplasty following acetabular fractures. The study included 39 males and 6 females. The age of the patients ranged from 32 to 61 with a mean of 46.4 years. The indication for surgery was secondary osteoarthritis in 35 patients and avascular necrosis of the femoral head in the remaining ten. The follow up period ranged from 7 to 15 years with a median of 10.3 years. Uncemented total hip prostheses were used in 37 cases while 8 cases had hybrid prostheses with cemented cups and uncemented stems. Thirty patients (66.7%) needed autogenous acetabular bone grafting. There has been a statistically significant improvement from a preoperative mean Oxford hip score of 16 to a postoperative mean score of 39.8 (p < 0.001). At the end of follow up, two cases had revision for cup loosening. The complications included one case of transient sciatic nerve palsy, and two cases of heterotopic ossification. Currently, total hip replacement remains the best option for end stage post traumatic arthritis. There are technical challenges associated with this replacement surgery which the surgeon should be aware of.

Active Patients

More total hip arthroplasty (THA) is performed worldwide and especially in younger and more active patients compared to earlier decades. One of the focuses of THA research in the future will be on optimizing the radiological follow-up of these patients using 2D and 3D measurements of implants position while reducing the radiation dose delivered. Low-dose EOS® imaging is an innovative slot-scanning radiograph system providing valuable information in patient functional positions (standing, sitting and even squatting positions). EOS has been proven accurate and reliable without significant inconvenience caused by the metallic artifacts of implants. The ability to obtain precise data on implant orientation according to the patient posture opens new perspectives for a comprehensive analysis of the pelvic frontal and sagittal balance and its potential impact on implants function and failures. We report our 8 years experience on our first 300 THA patients using this technology routinely for pre and post op evaluation. Our results will be compared and confronted with the actual literature about this innovative technology. We shall especially emphasize our experience about patients with abnormal posture and the evolution of the subject over time, because the phenomenon of an aging spine is frequently associated with the process of aging hips.

Total Hip Prostheses

Thirty uncemented porous-coated anatomic (PCA) total hip prostheses were implanted in 27 patients. The average age at the time of surgery was 54 years, and the average follow-up was 4.5 years. The average hip rating score was 88 points. Three patients had thigh pain at follow-up and fifteen had a mild limp, related to a weakness of the gluteus medius and minimus. On radiographic examination, we observed a good bone ingrowth of the implant in all patients. No aseptic loosening was radiographically demonstrated. No relationship was found between pain in the thigh and the various radiographic parameters studied (ra-diodense lines, sclerosis, varus position of the stem).

Component Migration

A total of 102 uncemented Link Rippen System (RS) total hip prostheses were implanted in 100 patients whose mean age was 57 years. The Merle d'Aubigné hip score was 9.3 preoperatively and 15.3 at the latest follow-up. The thigh was painful in 56 per cent; 5 per cent had moderate or severe pain. Forty-five per cent of patients had a slight limp and 9 per cent a severe limp at the most recent follow-up. Fifteen per cent still needed a cane. A Kaplan-Meier survivorship analysis revealed a 74 per cent probability of survival at 6 years. Serial radiographic evaluations revealed that 16 per cent of patients (non-revised hips) had acetabular component migration, 10 per cent had continuous femoral radiolucen-cies, 14 per cent had subsidence and 31 per cent progressive varus migration.

End Stage

Introduction. Management of acetabular fractures is challenging, especially when a medial acetabular fracture is complicated by central hip dislocation. We retrospectively investigated the clinical outcome and risk factors of secondary hip osteoarthritis requiring total hip arthroplasty after the surgical treatment of acetabular fractures with central hip dislocation. Materials and Methods. The medical records of all patients who had acetabular medial wall fractures with central hip dislocation treated with open reduction and internal fixation by a single surgeon between January 2015 and June 2017 were reviewed. Surgical reduction was performed with the modified Stoppa with/without the Kocher-Langenbeck (KL) approach. Patients were followed for a minimum of three years, and the Majeed scoring system was used for functional evaluation. Multivariate logistic regression analysis was used to assess the association of patients’ characteristics with the likelihood of advanced posttraumatic arthritis developing with conversion to total hip arthroplasty. Results. Fifty patients were included in this study, with disease classified as AO/OTA 2018 62B/62C. Thirty-five patients (70%) had good or excellent Majeed pelvic scores. Eleven patients (22%) eventually received total hip arthroplasty because of end-stage posttraumatic arthritis. Three risk factors identified for total hip arthroplasty were male sex, initial marginal impaction, and sciatic nerve injury. Kaplan-Meier survivorship analysis estimated that the cumulative probability of free-from-end-stage arthritis was 78% (95% confidence interval, 73%–90%) at the 5-year follow-up. Conclusion. Surgical fixation with the modified Stoppa and the KL approach for acetabular medial wall fractures with central hip dislocation is an effective approach with a satisfactory functional outcome. A prodromal factor was marginal impaction concomitant with articular damage. The trauma of high axial loading and the occupational distribution (males performing heavy manual labor and heavy lifting) with preoperative sciatic nerve injury increased the odds of developing end-stage arthritis.

Total Hip Prostheses

Abstract Modern hip replacements were developed in the late 1950s and have since evolved in surgical approaches, implants, and postoperative care. Consequently, surgeons use a wide variety of methods to implant more than 120000 total hip prostheses in the United States per year (National Institute of Health, 1994).
