RESUMEN

AIM: To explore the perceptions and experiences of members of the British Hip Society (BHS) as they relate to culture, diversity and inclusion in the professional sphere. METHOD: BHS members participated in an anonymised online survey in 2021. Quantitative and qualitative data were collected on demographics, professional experiences and perceptions of workplace culture. Members provided suggestions for improving working culture and supporting inclusivity. RESULTS: A 45% response rate (n=217) was achieved. Most respondents were male consultant surgeons, of white ethnicity. Almost a quarter of respondents reported experiencing barriers to career progression within the hip subspecialty. Experience of barriers was more common among women and those of non-white ethnicity. Several members experienced an elitist, exclusive culture in the BHS which is closed to outsiders. Thematic analysis of textual data revealed narratives which portray the perception of the society as a closed-door society, and described a clique culture in orthopaedics, and the pervasiveness of discrimination and banter. CONCLUSION: We found that barriers to inclusion and diversity exist within the professional society. Exploring the narratives around these has informed strategies to overcome them and has shaped future BHS initiatives. To ensure our patients receive the best possible surgical care, it is vital that those with the skills and expertise to deliver it, are supported by the Society and feel a sense of belonging and representation.

RESUMEN

INTRODUCTION: With the emergence of the COVID-19 pandemic, all elective surgery was temporarily suspended in the UK, allowing for diversion of resource to manage the anticipated surge of critically unwell patients. Continuing to deliver time-critical surgical care is important to avoid excess morbidity and mortality from pathologies unrelated to COVID-19. We describe the implementation and short-term surgical outcomes from a system to deliver time-critical elective surgical care to patients during the COVID-19 pandemic. MATERIALS AND METHODS: A protocol for the prioritisation and safe delivery of time-critical surgery at a COVID-19 'clean' site was implemented at the Nuffield Health Exeter Hospital, an independent sector hospital in the southwest of England. Outcomes to 30 days postoperatively were recorded, including unplanned admissions after daycase surgery, readmissions and complications, as well as the incidence of perioperative COVID-19 infection in patients and staff. RESULTS: A total of 128 surgical procedures were performed during a 31-day period by a range of specialties including breast, plastics, urology, gynaecology, vascular and cardiology. There was one unplanned admission and and two readmissions. Six complications were identified, and all were Clavien-Dindo grade 1 or 2. All 128 patients had preoperative COVID-19 swabs, one of which was positive and the patient had their surgery delayed. Ten patients were tested for COVID-19 postoperatively, with none testing positive. CONCLUSION: This study has demonstrated the implementation of a safe system for delivery of time-critical elective surgical care at a COVID-19 clean site. Other healthcare providers may benefit from implementation of similar methodology as hospitals plan to restart elective surgery.

RESUMEN

Aims: The aim of this study was to report the initial results of the Exeter V40 stem, which became available in 2000. Patients and Methods: A total of 540 total hip arthroplasties (THAs) were performed in our unit using this stem between December 2000 and May 2002. Our routine protocol is to review patients postoperatively and at one, five, and ten years following surgery. Results: A total of 145 patients (26.9%) died before ten years and of the remaining 395 stems, 374 (94.7%) remain in situ. A total of 21 well-fixed stems (5.3%) were revised. Ten were exchanged using a cement-in-cement technique to facilitate acetabular revision. Three were revised for infection, one for instability, one for fracture of the stem, and six following a periprosthetic fracture. An additional 16 acetabular components (4.1%) were revised; five for aseptic loosening and 11 for instability. There were no revisions for aseptic loosening of the stem, and no evidence of aseptic loosening in any hip. The fate of every stem is known and all patients remain under review. Survivorship, with revision of the stem for aseptic loosening as the endpoint, was 100%. At 13.5 years, the Kaplan-Meier survival rate for all-cause revision of the stem was 96.8% (95% confidence interval (CI) 94.8 to 98.8) and all-cause revision (including acetabular revision, infection, and instability) was 91.2% (95% CI 88.3 to 94.1). Conclusion: Conclusion No stem was revised for aseptic loosening in this series. The contemporary Exeter V40 stem continues to perform well, and survival has remained comparable with that of the Exeter Universal stem. Cite this article: Bone Joint J 2018;100-B:1002-9.

RESUMEN

AIMS: We report the incidence of radiolucent lines (RLLs) using two flanged acetabular components at total hip arthroplasty (THA) and the effect of the Rim Cutter. PATIENTS AND METHODS: We performed a retrospective review of 300 hips in 292 patients who underwent primary cemented THA. A contemporary flanged acetabular component was used with (group 1) and without (group 2) the use of the Rim Cutter and the Rimfit acetabular component was used with the Rim Cutter (group 3). RLLs and clinical outcomes were evaluated immediately post-operatively and at five years post-operatively. RESULTS: There was no significant difference in the incidence of RLLs on the immediate post-operative radiographs (p = 0.241) or at five years post-operatively (p = 0.463). RLLs were seen on the immediate post-operative radiograph in 2% of hips in group 1, in 5% in group 2 and in 7% in group 3. Five years post-operatively, there were RLLs in 42% of hips in group 1, 41% in group 2 and in 49% in group 3. In the vast majority of hips, in each group, the RLL was present in DeLee and Charnley zone 1 only (86%, 83%, 67% respectively). Oxford and Harris Hip scores improved significantly in all groups. There was no significant difference in these scores or in the change in scores between the groups, with follow-up. CONCLUSION: Despite the Rim Cutter showing promising results in early laboratory and clinical studies, this analysis of the radiological and clinical outcome five years post-operatively does not show any advantage over and above modern cementing techniques in combination with a well performing cemented acetabular component. For this reason, we no longer use the Rim Cutter in routine primary THA. Cite this article: Bone Joint J 2017;99-B:1450-7.

RESUMEN

AIMS: We present the clinical and radiological results at a minimum follow-up of five years for patients who have undergone multiple cement-in-cement revisions of their femoral component at revision total hip arthroplasty (THA). PATIENTS AND METHODS: We reviewed the outcome on a consecutive series of 24 patients (10 men, 14 women) (51 procedures) who underwent more than one cement-in-cement revision of the same femoral component. The mean age of the patients was 67.5 years (36 to 92) at final follow-up. Function was assessed using the original Harris hip score (HHS), Oxford Hip Score (OHS) and the Merle D'Aubigné Postel score (MDP). RESULTS: The mean length of follow-up was 81.7 months (64 to 240). A total of 41 isolated acetabular revisions were performed in which stem removal facilitated access to the acetabulum, six revisions were conducted for loosening of both components and two were isolated stem revisions (each of these patients had undergone at least two revisions). There was significant improvement in the OHS (p = 0.041), HHS (p = 0.019) and MDP (p = 0.042) scores at final follow-up There were no stem revisions for aseptic loosening. Survival of the femoral component was 91.9% (95% confidence intervals (CI) 71.5 to 97.9) at five years and 91.7% (95% CI 70 to 97) at ten years (number at risk 13), with stem revision for all causes as the endpoint. CONCLUSION: Cement-in-cement revision is a viable technique for performing multiple revisions of the well cemented femoral component during revision total hip arthroplasty at a minimum of five years follow-up.

RESUMEN

AIMS: We present a minimum 20-year follow-up study of 382 cemented Exeter Universal total hip arthroplasties (350 patients) operated on at a mean age of 66.3 years (17 to 94). PATIENTS AND METHODS: All patients received the same design of femoral component, regardless of the original diagnosis. Previous surgery had been undertaken for 33 hips (8.6%). During the study period 218 patients with 236 hips (62%) died, 42 hips (11%) were revised and 110 hips (29%) in 96 patients were available for review. The acetabular components were varied and some designs are now obsolete, however they were all cemented. RESULTS: With an endpoint of revision for aseptic loosening or lysis, survivorship of the stem at 22.8 years was 99.0% (95% confidence interval (CI) 97.0 to 100). One stem was revised 21 years post-operatively in a patient with Gaucher's disease and proximal femoral osteolysis. Survivorship with aseptic loosening or lysis of the acetabular component or stem as the endpoint at 22.8 years was 89.3% (95% CI 84.8 to 93.8). With an endpoint of revision for any reason, overall survivorship was 82.9% (95% CI 77.4 to 88.4) at 22.8 years. Radiological review showed excellent preservation of bone stock at 20 to 25 years, and no impending failures of the stem. CONCLUSION: The Exeter femoral stem continues to perform well beyond 20 years. Cite this article: Bone Joint J 2016;98-B:1441-9.

RESUMEN

Revision of a cemented hemiarthroplasty of the hip may be a hazardous procedure with high rates of intra-operative complications. Removing well-fixed cement is time consuming and risks damaging already weak bone or perforating the femoral shaft. The cement-in-cement method avoids removal of intact cement and has shown good results when used for revision total hip arthroplasty (THA). The use of this technique for the revision of a hemiarthroplasty to THA has not been previously reported. A total of 28 consecutive hemiarthroplasties (in 28 patients) were revised to a THA using an Exeter stem and the cement-in-cement technique. There were four men and 24 women; their mean age was 80 years (35 to 93). Clinical and radiographic data, as well as operative notes, were collected prospectively and no patient was lost to follow-up. Four patients died within two years of surgery. The mean follow up of the remainder was 70 months (25 to 124). Intra-operatively there was one proximal perforation, one crack of the femoral calcar and one acetabular fracture. No femoral components have required subsequent revision for aseptic loosening or are radiologically loose. Four patients with late complications (14%) have since undergone surgery (two for a peri-prosthetic fracture, and one each for deep infection and recurrent dislocation) resulting in an overall major rate of complication of 35.7%. The cement-in-cement technique provides reliable femoral fixation in this elderly population and may reduce operating time and rates of complication.

RESUMEN

OBJECTIVE: Restoration of acetabular anatomy and biomechanics at revision hip surgery by replacing deficient acetabular bone through impaction of allograft and/or autograft bone chips. INDICATIONS: Aseptic loosening of the socket due to osteolysis, bone loss from infection, iatrogenic bone loss due to implant removal, and in the primary setting protrusio acetabuli, dysplasia and previous acetabular fracture. CONTRAINDICATIONS: Large segmental peripheral acetabular defects which cannot be contained, the presence of untreated infection, unstable acetabular fractures, previous radiotherapy to the affected hip area. SURGICAL TECHNIQUE: Sound exposure of the acetabulum with delineation of the bony defect. Creation of a host environment suitable for bone graft and containment of segmental defects using rim mesh or porous augments. Impaction grafting using layered allograft or autograft bone chips of 0.8-1 cm(3), packed using hemispherical impactors, followed by cementing of a polyethylene acetabular component with pressurisation. POSTOPERATIVE MANAGEMENT: Partial weight bearing 6 weeks, modified depending on level of containment and intra-operative findings. RESULTS: A successful and reproducible technique with survival up to 87 % at 20 years for aseptic loosening in the revision setting.

RESUMEN

Impaction bone grafting for the reconstitution of bone stock in revision hip surgery has been used for nearly 30 years. Between 1995 and 2001 we used this technique in acetabular reconstruction, in combination with a cemented component, in 304 hips in 292 patients revised for aseptic loosening. The only additional supports used were stainless steel meshes placed against the medial wall or laterally around the acetabular rim to contain the graft. All Paprosky grades of defect were included. Clinical and radiographic outcomes were collected in surviving patients at a minimum of ten years after the index operation. Mean follow-up was 12.4 years (sd 1.5) (10.0 to 16.0). Kaplan-Meier survival with revision for aseptic loosening as the endpoint was 85.9% (95% CI 81.0 to 90.8) at 13.5 years. Clinical scores for pain relief remained satisfactory, and there was no difference in clinical scores between cups that appeared stable and those that appeared radiologically loose.

RESUMEN

The technique of femoral cement-in-cement revision is well established, but there are no previous series reporting its use on the acetabular side at the time of revision total hip replacement. We describe the technique and report the outcome of 60 consecutive acetabular cement-in-cement revisions in 59 patients at a mean follow-up of 8.5 years (5 to 12). All had a radiologically and clinically well-fixed acetabular cement mantle at the time of revision. During the follow-up 29 patients died, but no hips were lost to follow-up. The two most common indications for acetabular revision were recurrent dislocation (46, 77%) and to complement femoral revision (12, 20%). Of the 60 hips, there were two cases of aseptic loosening of the acetabular component (3.3%) requiring re-revision. No other hip was clinically or radiologically loose (96.7%) at the latest follow-up. One hip was re-revised for infection, four for recurrent dislocation and one for disarticulation of a constrained component. At five years the Kaplan-Meier survival rate was 100% for aseptic loosening and 92.2% (95% CI 84.8 to 99.6), with revision for any cause as the endpoint. These results support the use of cement-in-cement revision on the acetabular side in appropriate cases. Theoretical advantages include preservation of bone stock, reduced operating time, reduced risk of complications and durable fixation.

RESUMEN

The removal of all prosthetic material and a two-stage revision procedure is the established standard management of an infected total hip replacement (THR). However, the removal of well-fixed femoral cement is time-consuming and can result in significant loss of bone stock and femoral shaft perforation or fracture. We report our results of two-stage revision THR for treating infection, with retention of the original well-fixed femoral cement mantle in 15 patients, who were treated between 1989 and 2002. Following partial excision arthroplasty, patients received local and systemic antibiotics and underwent reconstruction and re-implantation at a second-stage procedure, when the infection had resolved. The mean follow-up of these 15 patients was 82 months (60 to 192). Two patients had positive microbiology at the second stage and were treated with six weeks of appropriate antibiotics; one of these developed recurrent infection requiring further revision. Successful eradication of infection was achieved in the remaining 14 patients. We conclude that when two-stage revision is used for the treatment of peri-prosthetic infection involving a THR, a well-fixed femoral cement mantle can be safely left in situ, without compromising the treatment of infection. Advantages of this technique include a shorter operating time, reduced loss of bone stock and a technically more straightforward second-stage procedure.

RESUMEN

We evaluated all cases involving the combined use of a subtrochanteric derotational femoral shortening osteotomy with a cemented Exeter stem performed at our institution. With severe developmental dysplasia of the hip an osteotomy is often necessary to achieve shortening and derotation of the proximal femur. Reduction can be maintained with a 3.5 mm compression plate while the implant is cemented into place. Such a plate was used to stabilise the osteotomy in all cases. Intramedullary autograft helps to prevent cement interposition at the osteotomy site and promotes healing. There were 15 female patients (18 hips) with a mean age of 51 years (33 to 75) who had a Crowe IV dysplasia of the hip and were followed up for a mean of 114 months (52 to 168). None was lost to follow-up. All clinical scores were collected prospectively. The Charnley modification of the Merle D'Aubigné-Postel scores for pain, function and range of movement showed a statistically significant improvement from a mean of 2.4 (1 to 4), 2.3 (1 to 4), 3.4 (1 to 6) to 5.2 (3 to 6), 4.4 (3 to 6), 5.2 (4 to 6), respectively. Three acetabular revisions were required for aseptic loosening; one required femoral revision for access. One osteotomy failed to unite at 14 months and was revised successfully. No other case required a femoral revision. No postoperative sciatic nerve palsy was observed. Cemented Exeter femoral components perform well in the treatment of Crowe IV dysplasia with this procedure.

RESUMEN

We report the outcome of the flangeless, cemented all-polyethylene Exeter acetabular component at a mean of 14.6 years (10 to 17) after operation. Of the 263 hips in 243 patients, 122 prostheses are still in situ; 112 patients (119 hips) have died, 18 hips have been revised, and three patients (four hips) were lost to follow-up. Radiographs at the final review were available for 110 of the 122 surviving hips. There were acetabular radiolucent lines in 54 hips (49%). Two acetabular components had migrated but neither patient required revision. The Kaplan-Meier survivorship at 15 years with 61 hips at risk with revision for any cause as the endpoint was 89.9% (95% confidence interval (CI) 84.6 to 95.2) and for aseptic loosening of the acetabular component or lysis 91.7% (95% CI 86.6 to 96.8). In 210 hips with a diagnosis of primary osteoarthritis, survivorship with revision for any cause as the endpoint was 93.2% (95% CI 88.1 to 98.3), and for aseptic loosening of the acetabular component 95.0% (95% CI 90.3 to 99.7). The cemented all-polyethylene Exeter acetabular component has an excellent long-term survivorship.

RESUMEN

The first 325 Exeter Universal stems (309 patients) implanted at the originating centre were inserted between March 1988 and February 1990 by a group of surgeons with differing experience. In this report we describe the clinical and radiological results at a mean of 15.7 years (14.7 to 17.3) after operation with no loss to follow-up. There were 97 patients (108 hips) with replacements still in situ and 31 (31 hips) who had undergone a further procedure. With an endpoint of revision for aseptic loosening, the survivorship at 17 years was 100% and 90.4% for the femoral and acetabular component, respectively. The mean Merle D'Aubigné and Postel scores at review were 5.4 (SD 0.97) for pain and 4.5 (SD 1.72) for function. The mean Oxford score was 38.4 (SD 9.8) (0 to 48 worst-to-best scale) and the mean combined Harris pain and function score was 73.2 (SD 16.9). Radiological review showed excellent preservation of bone stock in the proximal femur and no failures of the femoral component.

RESUMEN

The removal of well-fixed bone cement from the femoral canal during revision of a total hip replacement (THR) can be difficult and risks the loss of excessive bone stock and perforation or fracture of the femoral shaft. Retaining the cement mantle is attractive, yet the technique of cement-in-cement revision is not widely practised. We have used this procedure at our hospital since 1989. The stems were removed to gain a better exposure for acetabular revision, to alter version or leg length, or for component incompatibility. We studied 136 hips in 134 patients and followed them up for a mean of eight years (5 to 15). A further revision was required in 35 hips (25.7%), for acetabular loosening in 26 (19.1%), sepsis in four, instability in three, femoral fracture in one and stem fracture in one. No femoral stem needed to be re-revised for aseptic loosening. A cement-in-cement revision of the femoral stem is a reliable technique in the medium term. It also reduces the risk of perforation or fracture of the femoral shaft.

RESUMEN

The appearance and mechanism of femoral stem wear was studied in 172 retrieved femoral components, of which 74 stems had been stable in vivo. Macroscopic, microscopic, and nano-level scales of examination were used. Loss of stem surface in response to micromotion (wear) was found to affect 93% of stems. However, changes were frequently difficult to see with the naked eye, and in 19% of cases they would have been missed completely without the use of light microscopy. The surface finish of the prosthesis determined the mechanism of stem wear. Matte surfaces showed typical abrasive processes that also damage the cement, releasing particulate debris from the cement and metal surfaces. This may destabilize the stem within the cement. Polished stems showed a typical fretting appearance with retention of debris on the stem surface and without significant damage to the cement. These differences in wear mechanism between matte and polished stems have significant effects on stem function.

RESUMEN

BACKGROUND: Injuries to the knee menisci are common and operations to treat them are among the most common procedures performed by orthopaedic surgeons. OBJECTIVES: To evaluate the effects of common surgical interventions in the treatment of meniscal injuries of the knee. The four comparisons under test were: a) surgery versus conservative treatment, b) partial versus total meniscectomy, c) excision versus repair of meniscal tears, d) surgical access, in particular arthroscopic versus open. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group trials register, MEDLINE and bibliographies of published papers. Date of the most recent search: August 1998. SELECTION CRITERIA: All randomised and quasi-randomised trials which involved the above four comparisons or which compared other surgical interventions for the treatment of meniscal injury. DATA COLLECTION AND ANALYSIS: Trial inclusion was agreed by both reviewers who independently assessed trial quality, by use of a 12 item scale, and extracted data. Where possible and appropriate, data were presented graphically. MAIN RESULTS: Three trials, involving 260 patients, which addressed two (partial versus total meniscectomy; surgical access) comparisons were included. Partial meniscectomy may allow a slightly enhanced recovery rate as well as a potentially improved overall functional outcome including better knee stability in the long term. It is probably associated with a shorter operating time with no apparent difference in early complications or re-operation between partial and total meniscectomy. The long term advantage of partial meniscectomy indicated by the absence of symptoms (symptoms or further operation at six years or over: 14/98 versus 22/94; Peto odds ratio 0.55, 95% confidence interval 0.27 to 1.14) or radiographical outcome was not established. The results available from the only trial comparing arthroscopic with open meniscectomy were very limited in terms of patient numbers and length of follow-up. However it is likely that partial meniscectomy via arthroscopy is associated with shorter operating times and a quicker recovery. REVIEWER'S CONCLUSIONS: The lack of randomised trials means that no conclusions can be drawn on the issue of surgical versus non-surgical treatment of meniscal injuries, nor meniscal tear repair versus excision. In randomised trials so far reported, there is no evidence of difference in radiological or long term clinical outcomes between arthroscopic and open meniscal surgery, or between total and partial meniscectomy. Partial meniscectomy seems preferable to the total removal of the meniscus in terms of recovery and overall functional outcome in the short term.
