Intraoperative radiation exposure in hip arthroscopy: a systematic review.
R, Ayeni OR Abstract Fluoroscopy is used in hip arthroscopy (HA) for portal placement, instrument localisation, and guidance in bony resection. The recent increase in arthroscopic hip procedures may place patients and surgeons at risk for increased radiation exposure and radiation-induced complications. The purpose of the current systematic review was to assess intraoperative radiation exposure in HA. The systematic review was conducted according to PRISMA guidelines; inclusion criteria were studies assessing radiation exposure in HA. 9 studies including 994 patients were included. Mean age was 38.6 years a...

A new biarticular cement spacer technique for infected total hip and knee arthroplasty with massive bone loss.
We present the first results of a new biarticular cement spacer with antibiotic technique using a cephalomedullary nail for the treatment of infected hip arthroplasty involving complete femoral bone loss. RESULTS: 5 patients with a minimum follow-up of 1 year were included. In all cases 2-stage replacement due to hip periprosthetic infection was carried out, with the need for a biarticular complete femoral spacer in view of the magnitude of the bone defect. The infection was resolved in all patients, with no complications (spacer fracture or dislocation) associated to spacer use, and the patients were all able ...

A comparison of patient-reported outcome measures (PROMs) between short and conventional stem hip replacements: a systematic review and meta-analysis.
CONCLUSIONS: Our systematic review showed no difference in PROMs between short and conventional stem total hip replacements. This is in keeping with previous evidence but is a more comprehensive analysis. Short stems may have an important role in younger individuals as they allow preservation of proximal femoral bone, minimal access surgery and are amenable to abnormal anatomy. The current literature is hindered by non-uniform methodologies and outcome assessments across studies. Further, standardised, high quality evidence is required before widespread changes in practice.

Current evidence from a worldwide, multicentre, follow-up study of the recalled Articular Surface Replacement Hip System.
DISCUSSION: ASR XL THA patients are likely to exhibit blood metal ion increases without accompanying changes in symptom state, and therefore should be followed with annual blood tests at minimum. While appropriately selected ASR HRA patients were the most likely to exhibit low blood metal ion levels and report no symptoms, we recommend vigilant follow-up of all ASR patients to ensure that worsening clinical outcomes and asymptomatic soft tissue damage are not missed.

Survival of monoblock RM vitamys compared with modular PINNACLE cups: mid-term outcomes of 200 hips performed by a single surgeon.
CONCLUSIONS: Our study demonstrated that both cup designs had similar revision rates at mid-term follow-up, regardless the fact that the RM vitamys was used in a cohort of younger patients; which according to the literature would have led to earlier failures. Further long-term data are needed to evaluate the superiority of RM vitamys in the clinical setting, especially in the young.

Total hip arthroplasty in patients with osteoporosis.
Abstract There is a high prevalence of osteoporosis in patients undergoing total hip arthroplasty. There are several clinically relevant questions related to the management of such cases: the effect of ageing; the initial osseointegration of implants, especially when cementless THA is used; the effect of medical osteoporosis treatment on bone-implant interface; the incidence of intraoperative and late periprosthetic fractures, and the long-term survival of both cemented and cementless total hip arthroplasty performed for proximal femoral fractures and hip osteoarthritis. A critical review of the literature is pres...

Short proximal components in modular revision stems carry a higher risk for stem fractures.
r H Abstract INTRODUCTION: Fractures of modular hip revision stems are not uncommon. The current study examined implant-related factors on stem fracture. We hypothesised that in a modular stem the fracture risk is increased with the use of a short proximal implant component. MATERIALS AND METHODS: Anonymised data of all 32 patients in Switzerland with a Revitan modular hip system who had a stem fracture were obtained from the manufacturer. Implant and patient data were compared with all components implanted in Switzerland during the same time interval. RESULTS: Between 2002 and 2017, 4834 Revitan stems w...

Validation of a method to measure three-dimensional hip joint kinematics in subjects with femoroacetabular impingement.
CONCLUSIONS: This 3D to 2D registration method may offer a clinically useful solution for dynamic assessment of hip impingement. If 5-mm translation and 10° of rotation represent a clinically significant difference in hip kinematics, the method's accuracy of approximately 1 mm displacement and 1° rotation should enable detection of significant clinical differences.

Early detection of developmental dysplasia of hip by ultrasound.
CONCLUSIONS: In our 1-year period study, 50.9% of the newborns with DDH had neither any positive physical signs nor any risk factors, except being a female. In contrast, early universal US screening of the hip facilitated to diagnose all cases with hip dysplasia. Hip sonography is an effective mode of prevention in orthopaedics, however further studies are needed to compare the rates of operative procedures in selective versus universal screening models.

Outcomes of total hip arthroplasty in haemodialysis and renal transplant patients: systematic review.
CONCLUSIONS: Patients receiving haemodialysis or with a history of renal transplantation can expect good functional outcome following THA. However, the revision rate and deep infection rate are higher than would be expected in patients receiving THA for primary OA. Aseptic loosening is the most common reason for revision. Uncemented implants appear to be associated with lower failure rates both in haemodialysis patients and those who have had a transplant.

Degenerative changes of the hip following in situ fixation for slipped capital femoral epiphysis: a minimum 18-year follow-up study.
This study aims to evaluate functional, clinical and radiographic long-term outcomes after this procedure. METHODS: We reviewed 64 SCFE patients (76 SCFE hips) treated with ISF between 1983 and 1998. 82.9% were stable hips and 17.1% unstable according to Loder's definition. Initial radiographs demonstrated a mild slip in 50%, moderate in 41.3% and severe in 8.7% based on the Southwick angle. Long-term outcomes were assessed using the modified Harris Hip Score (mHHS), University of California at Los Angeles (UCLA) and Tegner activity scores, visual analogue scale (VAS) pain, VAS function, flexion-adduction-internal rot...

Correlation of MARS MRI findings with cup position, metal ion levels and function in metal-on-metal total hip arthroplasty.
Abstract INTRODUCTION: Metal-on-metal (MoM) total hip arthroplasties (THAs) have been linked with increased incidence of pseudotumours and revision rate. magnetic resonance imaging (MRI) is useful in diagnosing adverse reaction to metal debris (ARMD) disease but it is not known if MRI findings correlate with cup position. PATIENTS AND METHODS: From a cohort of 79 MoM THA, 34 MRI studies were available. MRI was classified according to Anderson classification. Mean follow-up was 7.1 years. Evaluation included cup position including margin of safety, measurement of metal ion levels and evaluation of funct...

Squeaking and other noises in patients with ceramic-on-ceramic total hip arthroplasty.
DISCUSSION: Noise evaluation may provide additional value for predicting failure of CoC bearings, though some questions should be better investigated in a dedicated prospective trial. PMID: 31328560 [PubMed - as supplied by publisher] (Source: Hip International)

Effect of marital status on patient-reported outcomes following total hip arthroplasty: a matched analysis with minimum 2-year follow-up.
CONCLUSIONS: Our study demonstrated inferior absolute PRO scores at latest follow-up for patients who were non-married compared to married following THA. These results show that while total hip replacement may still yield clinical benefit in all patients, non-married patients may ultimately achieve an inferior functional status, and expectations should be adjusted accordingly. Physicians should assess levels of psychosocial support in their patients prior to undergoing hip arthroplasty in order to optimise results.

Two-stage total hip arthroplasty following skeletal traction after extensive soft tissue release for severe limb-length discrepancy.
CONCLUSION: 2-stage THA following skeletal traction after extensive soft tissue release showed favourable results in terms of neurologic complication prevention and LLD resolution. However, a large proportion of patients still necessitated shortening osteotomy with a risk for nonunion at the osteotomy site. Though surgical procedures might be complicated and necessitate longer hospital stays, 2-stage THA with extensive soft tissue release might be an alternative treatment option for patients with severe LLD willing to resolve their limb length discrepancy.
