Revision Hip Surgery

Complete removal of femoral shaft cement during revision hip surgery is a difficult task prone to complications. If the cement bone interface is intact however, is there a place for its preservation and re-use with a new cemented stem? The results are reported of 51 cement within cement femoral stem revisions carried out between 1984 and 1991 with a minimum of 5 years’ follow-up, and a mean of 7.8 years. Excluding patients lost or deceased, 39 hips in 38 patients were reviewed clinically and radiologically. Eighty-two percent of these were still functioning in situ, 72% were excellent or good using the HSS scoring system and 97% had no radiological evidence of loosening. Femoral stem failure due to aseptic loosening occurred in 4 cases (10%) between 4 and 12 years after revision. Comparing this series to a previous revision hip series by the senior author, there appears to be no deterioration in long term results using this technique, and a better long term radiological outcome.

Purpose: To compare long-term patency and limb survival rates for the classical in situ surgical bypass procedure versus a minimally invasive technique for femorodistal revascularization. Methods: From May 1992 to June 1994, a prospective multicenter study was undertaken at 4 centers to evaluate the open versus closed technique for femorodistal bypass grafting. Of 97 patients enrolled in the trial, 73 patients (49 men; mean age 71 years) were assigned to the long-term follow-up protocol and prospectively randomized to the open (n = 38) or closed (n = 35) procedure. The classical open technique is characterized by a long incision over the length of the bypass graft, while the minimally invasive procedure involves only two short incisions over each anastomosis site (the side branches are closed with a coaxial embolization catheter system). Graft patency was evaluated with duplex imaging periodically throughout the 4-year observation period. Results: There was no statistically significant difference between the treatment groups with respect to age, sex, hypertension, ischemic heart disease, or smoking. However, the open group had a significantly greater incidence of diabetes (p = 0.037). Over a median 4.7-year follow-up (range 0.3–6.4), 9 (12%) patients (3 open and 6 closed) were lost to follow-up: 2 died and 7 refused the duplex examination. No significant differences in 4-year patency, limb salvage, or survival was demonstrated between the open versus closed treatment groups; 4-year secondary patency was 62% versus 64%, respectively, and limb salvage was 72% versus 86%. Conclusions: The closed technique for femorodistal in situ bypass procedures yields favorable long-term outcomes compared to the traditional open technique.

Introduction: 3rd generation ceramic bearings were introduced in total hip arthroplasty (THA) with the potential to have better mechanical strength and wear properties than their predecessors. At present, there are few studies looking at the long-term results of this latest generation of ceramic bearings. The purpose of our study was to investigate the long-term clinical and radiographic results of 3rd generation ceramic-on-ceramic THA and the incidence of ceramic specific complications such as squeaking and bearing surface fracture. Methods: The database of the senior author (J.D.W.) was reviewed. A total of 126 hip replacements performed in 108 patients (average age 39.6 years) with an average follow-up of 12.1 years (10-16 years) was identified. Clinical notes and plain radiographs were reviewed. To measure function, patients were contacted and an Oxford Hip Questionnaire was completed. Patients were also directly questioned about the presence of squeaking or any other sounds from the hip. Radiographs were evaluated for signs of wear, osteolysis, loosening and heterotopic ossification. The abduction angle of the acetabular component was measured. Results: The average Oxford Hip Score was 39.8 out of 48. Survivorship at 10 years was 94.6% (95% CI) with revision for any cause as the endpoint. There was 1 femoral head fracture, no osteolysis, no squeaking and no detectable wear. Conclusions: The good clinical and radiographic results for this series of patients are similar to other recent long-term studies looking at 3rd generation ceramic-on-ceramic THA. The results compare favourably with other bearing surfaces. The lack of osteolysis associated with this articulation is encouraging and may also make it a good choice for younger patients requiring total hip replacement.

We conducted a retrospective descriptive study of a series of 31 consecutively presenting patients who had been implanted with the Vibrant Soundbridge middle ear hearing device. All implantations had been performed by the senior author. Three of these patients had undergone bilateral implantation, and 4 others had undergone subsequent explantation and reimplantation in response to known or suspected device failure, giving us a total of 34 ears and 38 implants. Our goal was to ascertain short- and long-term outcomes as measured by conventional audiometry (pure-tone average at 1 to 6 kHz) and long-term benefit as defined by the use or nonuse of the device. We found that at the initial activation session 2 months postoperatively, the average hearing thresholds were within 3 dB of the preoperative thresholds in all 34 ears and all 38 implants. The mean short-term gain at activation in the 38 implants was 28.1 dB. Nineteen patients (20 ears) were available for long-term evaluation, with the length of follow-up ranging from less than 1 year to 11 years (mean: 7.3). Of these 20 ears, 9 demonstrated further gain (mean: 10.8 dB) despite any natural hearing deterioration; of the remaining 11 ears, gain was unchanged in 2, diminished in 7 (mean: −3.6 dB), and gain data were unavailable in 2. In the final analysis, there were 20 user ears and 10 nonuser ears; 4 ears were lost to all follow-up. We conclude that direct-drive hearing with the Vibrant Soundbridge middle ear hearing device is beneficial and provides sustained audiometric gain. Factors that have a significant impact on patient use or nonuse include difficulty in obtaining audiologic support and the direct and indirect costs of the device. Without audiologic or financial support, some patients may choose to become nonusers and to either switch to conventional hearing aid amplification or become apathetic about hearing improvement.

Background The Universal 2 is a widely used total wrist implant that aims to maintain function of the wrist. Purpose Promising mid-term results of the Universal 2 total wrist implant are described in the literature. This study evaluates the long-term results in terms of implant survival and patient satisfaction. Patients and Methods Patients who received a Universal 2 implant between 2004 and 2009 were retrospectively identified through a database search. Clinical outcome and complications of the implant were assessed by examination of the patient's medical records, X-rays, and a questionnaire, consisting of the Patient-Rated Wrist and Hand Evaluation questionnaire (PRWHE) and Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaires and additional questions. Results Twenty-five patients (26 wrists) were included in this study. Twenty-one (81%) Universal 2 implants remained in situ after a mean follow-up of 11 years. Moderate PRWHE (44) and QuickDASH (41) scores were found in these cases. Five Universal 2 implants failed and were converted to a total wrist arthrodesis after a mean period of 9.2 years due to distal component loosening (n = 3), recurrent luxation (n = 1), or recurrent synovitis (n = 1). Twenty-three (92%) patients were (very) satisfied with the Universal 2 implant. Conclusion The Universal 2 demonstrates a high (81%) implant survival with a high patient satisfaction after a mean follow-up of 11 years. Prospective studies of the Universal 2 implant are necessary to objectify improvement in wrist function and to provide a better comparison to other fourth generation wrist implants.

The Omnifit-HA femoral stem component has shown excellent results in early clinical studies. This is an independent prospective study of the outcome of a ydroxyapatite-coated femoral component implanted by one surgeon with an intermediate-term follow up. The senior author performed 103 consecutive uncemented total hip arthroplasties in 96 patients from July 1991 to December 1996. The components implanted were the Omnifit-HA femoral stem and the Omnifit PSL porous-coated acetabular shell. The mean age at the time of the index procedure was 52 years old (range, 27–78) and male:female ratio was 54:42. Three patients were deceased and four patients were lost to follow-up. The mean follow up was 10.3 years (range, 7.3–12.7 years). Clinical and radiographic evaluations were performed by an independent observer. The average preoperative and postoperative Harris Hip Scores were 55 and 92, respectively. The overall survivorship of the Omnifit-HA stem was 100% with no femoral revisions. The survivorship of the Omnifit PSL cup was 89.7% with 4 acetabular revisions for aseptic loosening and 6 polyethelene liner exchanges for osteolysis or late instability. The mean polyethylene wear rate was 0.24 mm per year. This long-term follow up shows that the use of circumferentially coated hydroxyapatite stems can protect against the migration of wear debris along the femoral stem.

Introduction This study aimed to evaluate the short and long-term results of endoscopic dacryocystorhinostomy (DCR) with and without silicone stenting in chronic dacrocystorhinitis due to postsaccal blockage. Methods The study involved a case series of consecutive 89 patients (128 eyes) who underwent endoscopic DCR. All patients were operated on by the senior author. The stent group comprised 63 eyes (44 patients), for which the DCR was performed between September 2002 and September 2005. The non-stent group with 65 eyes (45 patients) underwent the DCR between October 2005 and December 2006. The follow-up duration was up to 33 months after surgery. The statistical significance (p-value) was calculated using the chi-squared test. Results The short-term success rate at six months’ follow-up was 70% in the stent group and 97% in the non-stent group (p=0.0005) while the long-term success rate at 33 months was only 57% in stent group compared with 89% in the non-stent group (p=0.0003). Conclusions In this study, the non-stent group showed a higher success rate than the stent group on both short and longterm follow-up. Our study suggests that postoperative stents are not necessary for primary DCR and may be associated with a worse outcome.

Abstract Introduction The Exeter V40 cemented femoral stem was first introduced in 2000. The largest single-centre analysis of this implant to date was published in 2018, with excellent results at a minimum of 10-years for the first 540 cases performed at the designer centre in the Exeter NHS Trust. The aim of this current study is to report long term outcomes and survivorship for the Exeter V40 stem in a non-designer centre. Method All patients undergoing primary total hip arthroplasty using the Exeter V40 femoral stem between January 1st 2005 and January 31st 2010 were eligible for inclusion. Outcome measures included data on all components in situ beyond 10 years, death occurring within 10 years with components in situ and all-cause revision surgery. Results A total of 829 stems were included in the data set. Of these, 808 (97.5%) had no further surgery within the follow-up period; 648 stems (78.1%) were in situ beyond 10 years, and 165 (19.9%) were in situ at death before 10 years. The mean preoperative WOMAC score was 61±15.9 with a mean postoperative score of 20.4±19.3. Conclusions The Exeter V40 cemented femoral stem demonstrates excellent functional outcomes and survival when used in a high-volume non-designer centre.

Abstract BACKGROUND Occipitocervical junction instability can lead to serious neurological injury or death. Open surgical fixation is often necessary to provide definitive stabilization. However, long-term results are limited to small case series. OBJECTIVE To review the causes of occipitocervical instability, discuss the indications for surgical intervention, and evaluate long-term surgical outcomes after occipitocervical fixation. METHODS The charts of all patients undergoing posterior surgical fixation of the occipitocervical junction by the senior author were retrospectively reviewed. A total of 120 consecutive patients were identified for analysis. Patient demographic characteristics, occipitocervical junction pathology, surgical indications, and clinical and radiographic outcomes are reported. RESULTS The study population consisted of 64 male and 56 female patients with a mean age of 39.9 years (range, 7 months to 88 years). Trauma was the most common cause of instability, occurring in 56 patients (47%). Ninety patients (75%) were treated with screw/rod constructs; wiring was used in 30 patients (25%). The median number of fixated segments was 5 (O-C4). Structural bone grafts were implanted in all patients (100%). Preoperative neurological deficits were present in 83 patients (69%); 91% of those patients improved with surgery. Mean follow-up was 35.1 ± 27.4 months (range, 0-123 months). Two patients died, and 10 were lost to follow-up before the end of the 6-month follow-up period. Fusion was confirmed in 107 patients (89.1%). The overall complication rate was 10%, including 3 patients with vertebral artery injuries and 2 patients who required revision surgery. CONCLUSION Occipitocervical fixation is a durable treatment option with acceptable morbidity for patients with occipitocervical instability.
