    Dislocation of meniscal bearing insert is a rare but well-recognised complication in meniscal bearing unicompartmental knee arthroplasty (UKA). On the other hand, fracture of meniscal bearing insert of phase III Oxford UKA has only been reported once in the current literature. The authors report a case of fracture and posterior dislocation of one of the fragments of the meniscal bearing insert in a mobile bearing medial UKA. The fracture was only diagnosed during the revision surgery. The posteriorly dislodged fragment was subsequently retrieved through the same skin incision and a new polyethylene insert of the same size was implanted.

    We report on the medium term outcome of five patients (ten hips) who underwent one stage bilateral total hip arthroplasty. Both Harris Hip Scores and Oxford Hip Scores improved postoperatively as did range of motion. There was no radiographic evidence of loosening in any hip arthroplasty involved in this study, however one revision surgery was needed due to periprosthetic fracture. There were no increased medical complications. Based on our limited experience, we believe that one stage bilateral total hip arthroplasty is safe in selected patients.

    Infection after joint replacement surgery is problematic and difficult to treat. The utility of antibiotic laden bone cement for reduction of risk of infection in primary and revision joint replacement surgery has already been established in many studies. In this study, we examined the efficacy of bone cement containing cefuroxime, employing a modified in vitro Kirby-Bauer susceptibility model for investigation of 13 strains of organisms that are found in orthopaedic infections. Organisms investigated were broad spectrum and effective for Gram-positive, Gram-negative, aerobic organisms and anaerobes. Simplex P with added cefuroxime was effective against 8 out of 13 strains. Cefuroxime is stable during exothermic polymerisation of the cement, and is released from the cement at concentrations high enough to inhibit the growth of most organisms encountered after joint arthroplasty.

    INTRODUCTION: Low-level laser therapy (LLLT) is a practical, nonpharmacologic technique for reducing pain. This study evaluated the effect of LLLT on postoperative pain after root canal retreatment (RCR).

    METHODS: This study enrolled patients (N = 36) who required root canal retreatment (RCR) on mandibular molar teeth, presented with periapical lesions with periapical index scores of 2 or 3, and had a pain visual analog scale (VAS) <50 and a percussion pain VAS <50. The participants were divided into 2 groups: (1) patients scheduled for RCR followed by LLLT (n = 18) and (2) patients scheduled for RCR followed by a mock LLLT (placebo) (n = 18). Postoperative pain was assessed using the VAS. Data were collected and statistically analyzed with the chi-square test, the independent sample t test, and the Mann-Whitney U test (P = .05).

    RESULTS: On the first 4 days, postoperative pain significantly reduced in the LLLT group compared with the placebo group (P  .05). The number of patients who needed analgesics was lower in the LLLT group than in the placebo group (P

    From 1996 to 2001, 393 thyroidectomies were performed and 25 (6.4%) patients underwent reoperative thyroid surgery at Hospital Universiti Sains Malaysia. All reoperated patients had undergone one prior thyroid operation. All were females with an average age of 39.1 years (18-61 years). The most frequent indication for reoperation was cancer in resected specimen of an originally misdiagnosed carcinoma treated by partial thyroid resection. Final histological diagnosis of 25 reoperations showed thyroid carcinoma in 22 (88%) cases and multinodular goiter in 3 cases. The overall interval between the initial and the reoperative procedures ranged from 3 weeks to 15 years. There was no post-operative mortality after reoperation. Post-operative complications were discovered in 5 patients, as 3 (12%) of whom had transient hypocalcaemia, one (4%) had wound breakdown and one (4%) had permanent recurrent laryngeal nerve palsy. Reoperative thyroid surgery is an uncommon operation with high complication rate.

    Introduction: Medial migration is the paradoxical migration of the femoral neck element (FNE) superomedially against gravity with respect to the intramedullary component of the cephalomedullary device, increasingly seen in the management of pertrochanteric hip fractures with the intramedullary nail. We postulate that the peculiar anti-gravity movement of the FNE in the medial migration phenomenon stems from a ratcheting mechanism at the intramedullary nail-FNE interface, which should inadvertently produce unique wear patterns on the FNE that can be seen with high-powered microscopy. By examining the wear patterns on retrieved implants from patients with medial migration, our study aims to draw clinical correlations to the ratcheting mechanism hypothesis.

    Material and Methods: Four FNEs were retrieved from revision surgeries of four patients with prior intramedullary nail fixation of their pertrochanteric hip fractures complicated by femoral head perforation. The FNEs were divided into two groups based on whether or not there was radiographic evidence of medial migration prior to the revisions. Wear patterns on the FNEs were then assessed using both scanning electron microscopy and light microscopy.

    Results: Repetitive, linearly-arranged, regularly-spaced, unique transverse scratch marks were found only in the group with medial migration, corresponding to the specific segment of the FNE that passed through the intramedullary component of the PFNA during medial migration. These scratch marks were absent in the group without medial migration.

    Conclusion: Our findings are in support of a ratcheting mechanism behind the medial migration phenomenon with repetitive toggling at the intramedullary nail-FNE interface and progressive propagation of the FNE against gravity.

    We present a unique case of tibial post fracture of a posterior-stabilised total knee arthroplasty (PS-TKA) using highly crosslinked polyethylene (HXLPE) in the unafflicted limb of a patient who had poliomyelitis. The tibial post is an upright structure perpendicular to the PE insert articular surface which articulates with the cam of the femoral component to prevent excessive posterior translation of the tibia. We explore the choice of PS polyethylene (PE) inserts in patients with neuromuscular disorders (NMD). A 74-year old gentleman presented with recurrent knee pain seven years after the index PS-TKA with HXLPE. The TKA was performed on the unafflicted left limb (contralateral to the weak side affected by poliomyelitis). The posterior drawer test was positive. During the single-stage revision surgery, the HXLPE tibial post was noted to be broken. The liner was replaced with a thicker non-HXLPE. The patient achieved an excellent outcome at one-year post-surgery. This is the first report of HXLPE tibial post fracture in the unaffected knee of a patient with NMD affecting the lower limb. The HXLPE's reduced resistance to fatigue crack propagation might not be suitable in PS-TKA where there might be focal stress points on the tibial post, which was amplified in this case as it was the limb that the patient most depended on. When managing end-stage osteoarthritis with TKA in the unafflicted knee of a patient with NMD causing lower limb weakness, the selection of polyethylene material in PS-TKA may need more consideration than previously thought.

    INTRODUCTION AND HYPOTHESIS: To study the outcomes following repeat midurethral sling (MUS) surgery in patients with persistent or recurrent stress urinary incontinence after failure of primary MUS surgery and risk factors for surgical failure.

    METHODS: The medical records of 24 patients who underwent repeat MUS surgery at a single tertiary center from January 2004 to February 2014 were reviewed. The types of MUS used for the repeat surgey were transobturator, retropubic and single incision slings. Objective cure was defined as no demonstrable involuntary leakage of urine during increased abdominal pressure in the absence of a detrusor contraction observed during filling cystometry, and subjective cure was defined as a negative response to Urogenital Distress Inventory six (UDI-6) question 3 during follow-up between 6 months and 1 year postoperatively. The change in the inclination angle between the urethra and pubic axis was measured with introital ultrasonography and the cotton swab test performed.

    RESULTS: The objective and subjective cure rates were 79.2 % and 75 %, respectively. There were no differences in demographics between the patients with failure of surgery and those with successful surgery. Significant independent risk factors for failure of repeat MUS surgery were a change in cotton swab angle at rest and straining of <30° (OR 4.6, 95 % CI 2.5 - 7.9°), a change in inclination angle of <30° (OR 4.6, 95 % CI 2.5 - 7.9°), intrinsic sphincter deficiency (OR 3.4, 95 % CI 1.8 - 6.1) and a mean urethral closure pressure of <60 cm H2O (OR 2.9, 95 % CI 1.5 - 4.5). In one patient the bladder was perforated.

    CONCLUSIONS: Repeat MUS surgery is safe and has a good short-term success rate, both objectively and subjectively, with independent risk factors for failure related to bladder neck hypomobility and poor urethral function.

    BACKGROUND: This study aims at determining the average long-term result of revision total hip arthroplasty (THA) using the acetabular reinforcement ring with a hook (ARRH) and bone grafting in severe acetabular bony defect. Expected 15-year survival of ARRH in revision THA is included in the study.

    METHODS: Retrospective review of 48 patients (48 hips) with follow-up duration of average 11.4 years (range, 6.1-21.4 years) was conducted. At each follow-up, Harris hip score was used to assess functional outcome, and radiographic acetabular component osteolysis was measured by DeLee and Charnley classification. Bone defects were assessed preoperatively and intraoperatively using American academy of orthopedic surgeons and Paprosky classification. The common modes of ARRH failures were evaluated. Bone consolidation, presence of heterotopic ossification, and complications such as infection and dislocation were recorded.

    RESULTS: The bone defects were varied and included cavitary, segmental, and combined defects without any pelvic discontinuity. Mean Harris hip score improved from 52.6 points preoperatively to 82.0 points postoperatively. Nine acetabular revisions and 3 stem revisions (2 concurrent with acetabular revisions and 1 isolated stem revision) were performed. There were 5 infected cases and 1 patient with recurrent dislocation. The 11.4-year survival of revision THA with ARRH was 71% as the end point for acetabular revision surgery for any reason. The expected 15-year survival of revision THA with ARRH was 60%. The most common failure mode of ARRH was superomedial migration followed by lateral migration.

    CONCLUSION: ARRH combined with bone grafting produces relatively good average long-term clinical results.

    BACKGROUND: Bariatric surgery has been shown to be safe and effective in patients aged 60-75 years; however, outcomes in patients aged 75 or older are undocumented.

    METHODS: Patients aged 75 years and older who underwent bariatric procedures in two academic centers between 2006 and 2015 were studied.

    RESULTS: A total of 19 patients aged 75 years and above were identified. Eleven (58%) were male, the median age was 76 years old (range 75-81), and the median preoperative body mass index (BMI) was 41.4 kg/m2 (range 35.8-57.5). All of the bariatric procedures were primary procedures and performed laparoscopically: sleeve gastrectomy (SG) (n = 11, 58%), adjustable gastric band (AGB) (n = 4, 21%), Roux-en-Y gastric bypass (RYGB) (n = 2, 11%), banded gastric plication (n = 1, 5%), and gastric plication (n = 1, 5%). The median operative time was 120 min (range 75-240), and the median length of stay was 2 days (range 1-7). Three patients (16%) developed postoperative atrial fibrillation which completely resolved at discharge. At 1 year, the median percentage of total weight loss (%TWL) was 18.4% (range 7.4-22.0). The 1-year %TWL varied among the bariatric procedures performed: SG (21%), RYGB (22%), AGB (7%), and gastric plication (8%). There were no 30-day readmissions, reoperations, or mortalities.

    CONCLUSION: Our experience suggests that bariatric surgery in selected patients aged 75 years and older would be safe and effective despite being higher risk. Age alone should not be the limiting factor for selecting patients for bariatric surgery.

    Over a period of nine years, from June 1976 through May 1985, 18 cases of ruptured sinus of Valsalva aneurysms were seen at the University Hospital, Kuala Lumpur (UK KL). Seven of these cases were treated surgically. The majority of patients were males, with a mean age of 26.6 years. All cases were symptomatic. The site of aneurysm was the right coronary sinus in five patients and the non-coronary sinus in two patients. All aneurysms ruptured into the right ventricle. The fistula was closed via a transaortic approach. In addition, repair of the right heart chamber was necessary in six patients. There were no deaths. Clinically significant morbidity included aortic regurgitation in one patient and residual fistula requiring reoperation in another. The long term follow-up at two years was excellent.

    We report here a case of a kidney transplant recipient in whom the ureter was initially implanted into the peritoneum. Excessive ultrafiltration volume and reversal of serum vs dialysate creatinine ratio when the patient was recommenced on continuous ambulatory peritoneal dialysis first suggested the diagnosis which was subsequently confirmed by a plain abdominal x-ray demonstrating placement of ureteric stent in the peritoneum. This rare complication was successfully corrected with surgical re-implantation of ureter into the bladder and 5 years later, the patient remains well with good graft function.

    We report a case of enucleation for painful blind eye secondary to recurrent bleeding from choroidal neovascularisation in an eye that was irradiated following presumed metastatic breast carcinoma to the choroid. A 58-year-old woman with a history of treated breast malignancy presented with haemophthalmus and intractable glaucoma in the right eye. One year previously she had presented with right vitreous haemorrhage with subretinal mass that had been irradiated given her history of breast carcinoma. Following irradiation, vitrectomy was performed to clear the blood. Intraoperative and postoperative angiography findings suggested a diagnosis of breakthrough bleeding secondary to polypoidal choroidal vasculopathy. At this presentation, however, the intraocular bleeding was recurrent resulting in elevated intraocular pressure and pain. Despite repeat surgery and medical therapy, the eye had to be enucleated. Histopathology showed choroidal neovascularisation.

    BACKGROUND: To explore the clinical outcomes, safety and effectiveness of suture cruroplasty versus mesh repair for large hiatal hernias (HHs) by an updated meta-analysis.

    MATERIAL AND METHODS: Randomized controlled trials evaluating the effects of these 2 treatment modalities were searched from PubMed and other electronic databases between January 1991 and July 2018. The outcome variables analyzed included operating time, complications, recurrence of HH or wrap migration, reoperation, hospital stay and quality of life.

    RESULTS: Five randomized controlled trials totaling 478 patients (suture=222, mesh=256) were analyzed. For reoperation variable, the odds ratio was significantly 3.26 times higher for the suture group. For recurrence of HH, the odds ratio for the suture group was nonsignificantly 1.65 times higher compared with the mesh group. Comparable effects were noted for all other variables.

    CONCLUSIONS: Mesh repair seems to be superior to suture cruroplasty for large HH repair. Therefore, the routine use of mesh may be advantageous in selected cases.

    BACKGROUND AND AIMS: Partial fundoplication is commonly performed in conjunction with Heller Myotomy. It is, however, controversial whether anterior Dor or posterior Toupet partial fundoplication is the antireflux procedure of choice. The aim was to perform a systematic review and meta-analysis of studies comparing these two procedures.

    MATERIAL AND METHODS: A search of PubMed, Cochrane database, Medline, Embase, Science Citation Index, Google scholar and current contents for English language articles comparing Dor and Toupet fundoplication following HM between 1991 and 2018 was performed. The outcome variables analyzed included operating time, length of hospital stay (LOHS), overall complication rate, quality of life (QOL), postoperative reflux, residual postoperative dysphagia, treatment failure and reoperations. The meta-analysis was prepared in accordance with the PRISMA-P statement.

    RESULTS: Seven studies totaling 486 patients (Dor = 245, Toupet = 241) were analyzed. LOHS was significantly shorter for Toupet repair compared to Dor procedure (WMD 0.73, 95% CI 0.47 to 0.99; P
