[Crenelation of Beall's prostheses in mitral position: apropos of 21 reoperated cases].

The authors report their experience of 21 revision operations for malfunction of the Beall Surgitool 104 prosthesis used in the mitral position. The incidence and uniformity of the disorders found in the prostheses suggest that these changes are produced inevitably usually during the fourth year. The disc becomes kinked, the mountings eroded, and the teflon ring torn. The clinical features are the onset of heart failure, anaemia, or a thrombo-embolic episode. These three findings may occur individually or in association. The authors do not advise systematic revision surgery, but conclude that close follow-up is essential in the case of all patients who have had a Beall prosthesis. Early signs of failure should be revealed by clinical examination, the level of LDH, and by phonocardiogram and echocardiogram studies. Leaving aside thrombo-embolic episodes and severe anaemia which themselves constitute indications for revision surgery, the decision to replace the damaged prosthesis should be taken as soon as the first signs of cardiac failure are detected.

Intact canal wall mastoidectomy.

A series of 70 cholesteatoma patients is reported. The incidence of recurrent and residual cholesteatoma following intact canal wall mastoidectomy (ICWM) is 22%. Revision surgery is discussed, and data are presented to support performing ICWM as a revision procedure. The place of ICWM in chronic ear surgery is discussed.

[Diplopia frequency as a result of the surgical treatment of concomitant squint].

Postoperative diplopia in cases of congenital strabismus or early onset occured in 5% of patients operated on in 1977. We cannot calculate the frequency of diplopia in children operated on up to the age of 9 years old (290 cases) since no child suffered from diplopia. Its incidence-5% (9 out of 177 cases) relates to patients older than 9 years at the time of surgery, 6 patients out of 20 cases with consecutive exotropia complained of diplopia (following revision surgery). Amblyopia - foveal or eccentric fixation-alone seems to be a less important risk than consecutive exotropia. Preoperative wearing of prism to compensate the objective angle of squint over a few days can reduce but not exclude the general risk of postoperative diplopia.

Long-term results of open cavity and tympanomastoid surgery of the chronic ear.

The results of surgery for chronic middle ear infection in 307 patients (347 ears) are reported. All ears were operated on according to one of two procedures: (i) the operative cavity was left open after removal of the posterior canal wall, or (ii) a tympanomastoidectomy with intact canal wall was done. When necessary, removal of disease in the tympanum with or without reconstruction of the sound-conducting mechanism of the middle ear was performed. Cholesteatoma was present in 56% of the ears. Open cavity surgery with no reconstruction was done in 53%. In the remaining 47%, tympanomastoidectomy was performed and in approx. half of these ears reconstruction was undertaken. The postoperative follow-up period averaged 9 years. Residual cholesteatoma was found in 9%. In 4% of the ears undergoing tympanomastoidectomy a retraction pocket cholesteatoma developed. During the follow-up period 13% of the ears required revision surgery. Nineteen per cent of the ear with open cavities were discharging and, in addition, crusts were observed in 13%. In the tympanomastoidectomy group, discharing ears were seen in 26%. As a rule, hearing was not affected by surgery. The mean elevation of the pure tone threshold was 6.5 dB on account of sensorineural loss, while the speech reception threshold shift was 11 dB. The results testify to the importance of removing the posterior canal wall in ears with chronic middle ear infection associated with cholesteatoma.

The meatally based musculoperiosteal flap in cavity obliteration.

A meatally based musculoperiosteal flap that was formed for radical mastoid cavity obliteration was deliberately excised during revision surgery in three cases of recurring tympanic cholesteatoma. The flaps, which contained subcutaneous connective tissue, were well vascularized and contained large, viable muscle bundles and many nerve trunks from the postauricular branch of the facial nerve. In two cases, the periosteum-attached bone chips that had been removed from the patient's mastoid tip region and implanted to form a new bony canal wall were viable and gave the intended support for the meatus after radical ear surgery.

Revision of the endolymphatic subarachnoid shunt for Meniere's disease. Review of 59 cases.

Members of the Otologic Medical Group, Inc, Los Angeles, diagnose Meniere's disease in patients with fluctuating hearing loss, fluctuating tinnitus, episodic vertigo, and fluctuating pressure symptoms in the ear. Treatment is vasodilation. If medical treatment fails, an endolymphatic subarachnoid shunt operation is performed. If the shunt relieves symptoms for three or more months but symptoms then recur, revision of the shunt is recommended. If the revision surgery also fails, a destructive procedure is suggested.

Efficacy and safety of Vertebral Body Sliding Osteotomy (VBSO) versus Anterior Cervical Corpectomy and Fusion (ACCF): A systematic review and meta-analysis.

Anterior cervical corpectomy and fusion (ACCF) is an established treatment for complex cervical myelopathy and ossification of the posterior longitudinal ligament (OPLL), yet it carries risks of dural injury and graft-related failure. Vertebral body sliding osteotomy (VBSO) is a novel technique that avoids direct OPLL manipulation by translating the vertebral body anteriorly to enlarge the spinal canal. Although early studies suggest VBSO may reduce complications, evidence remains limited to retrospective cohorts from the technique's developers, with no high-level synthesis directly comparing it to ACCF. We therefore conducted this meta-analysis to compare clinical outcomes, complications, and radiographic parameters between VBSO and ACCF, while critically evaluating the certainty of the evidence and its generalizability. A systematic search of PubMed, Embase, Scopus, the Cochrane Library, and Web of Science (through June 2025) identified four retrospective cohort studies (449 patients; VBSO n = 209, ACCF n = 240). A critical limitation of the included evidence is that all studies originated from a single institution (Asan Medical Center, Seoul, Korea) with overlapping enrollment periods (2006-2020), increasing the risk of duplicate patient cohorts. Furthermore, the first author (D.-H. Lee) is the same across all included studies, introducing substantial surgeon-expertise bias. Outcomes included neurological recovery, functional outcomes, complications, and radiographic parameters. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. Neurological recovery and functional outcomes were comparable between groups. ACCF showed slightly higher postoperative JOA scores (MD -0.59, 95% CI -0.96 to -0.22; p < 0.01), though the clinical relevance is uncertain. VBSO was associated with reduced risks of graft subsidence (RR 0.23; p < 0.01), pseudarthrosis (RR 0.25; p < 0.01), revision surgery (RR 0.17; p < 0.01), and neurological deterioration (RR 0.17; p = 0.02). CSF leakage appeared to be less frequent with VBSO, but the difference was not statistically significant. VBSO was also associated with greater postoperative cervical lordosis and shorter hospital stays. However, these findings must be interpreted with extreme caution: leave-one-out sensitivity analyses revealed that the results for postoperative JOA score, neurological deterioration, and pseudarthrosis were fragile and driven by a single large study, meaning these apparent advantages may not be robust. In addition, GRADE assessment revealed very low certainty across all assessed outcomes. Given the very low certainty of evidence, the preliminary nature of the available data, the fragility of several key findings, and the critical limitations of the underlying studies (single institution, overlapping patient cohorts, developer bias, and systematic imbalance in follow-up duration), the observed differences should be considered hypothesis-generating rather than definitive. VBSO should not be considered a proven superior alternative to ACCF based on the current evidence. Prospective, multicenter, international studies with balanced follow-up durations conducted by independent surgical teams are required before broader adoption can be recommended.

First UK use of bacteriophage therapy with DAIR for chronic Staphylococcus aureus prosthetic joint infection.

BACKGROUND: Chronic Staphylococcus aureus prosthetic joint infection (PJI) remains difficult to manage when surgical revision and long-term antibiotics are not feasible. Bacteriophage therapy is emerging as a potential adjunct, though experience in orthopedic infections, particularly in the United Kingdom, is limited. CASE SUMMARY: We report the first UK case of intra-articular bacteriophage therapy administered alongside debridement, antibiotics, and implant retention (DAIR) for chronic methicillin-sensitive Staphylococcus aureus knee PJI. An 81-year-old man with multiple comorbidities developed persistent infection following revision knee arthroplasty, with recurrent sinus formation despite multiple surgical washouts and prolonged suppressive antibiotics. Major revision surgery and amputation were not viable options. Following a multidisciplinary review through the UK Clinical Phage Network, targeted phage therapy was pursued as salvage treatment. Phage susceptibility testing identified an active lytic phage (ISP). The patient underwent open DAIR with intra-articular phage administration, adjunctive local antibiotics, short-course intravenous antimicrobials, and subsequent oral suppressive therapy. Two further intra-articular phage doses were administered postoperatively. Initial sinus closure occurred, but recurrence developed within 4 weeks. At 18 months, symptoms were partially improved with better mobility and reduced inflammation, though one sinus tract persisted. No significant adverse effects were observed. Whole-genome sequencing of pretreatment isolates demonstrated a predominantly ST5 S. aureus genotype with conserved biofilm-associated virulence genes and limited antimicrobial resistance in addition to clonal diversification consistent with chronic biofilm infection. CONCLUSION: This case demonstrates the feasibility and safety of intra-articular phage therapy during DAIR in a UK setting but highlights biological, logistical, and pharmacological factors that may limit efficacy in advanced chronic PJI.

[Mitral commissurotomy under direct vision. 37 cases].

1 188 mitral commissurotomies were carried out between 1962 and 1976, 37 of them (3.1%) being under direct vision. The two operative deaths (5.4%) occurred early in the series. Longer term follow-up showed that 3 cases died secondarily, and 3 had revision surgery. The main complication was mitral incompetence (51% of operated cases had a systolic murmur). The varying indications and results are presented; these justify a prospective study, but not a recommendation for the systematic adoption of mitral commissurotomy by an open heart technique.

[Aortic valve replacement. Apropos of a series of 117 patients].

With a series of 117 aortic valve replacements, the authors have examined the results in relation to the method of protecting the myocardium while the aorta is clamped off. There does not appear to be much difference between coronary perfusion and the technique of profound local hypothermia by the perfusion of a chilled solution into the pericardium. Because of this, the authors remain in favour of the latter technique, which provides effective protection of the myocardium during periods of aortic occlusion sufficient for monovalvular replacements. An occlusion time of up to 90 minutes has been achieved without any major problems. Nevertheless, perfusion of the two coronary arteries is sometimes indicated, notably when profound local hypothermia cannot be employed at revision surgery, feeling of the pericardial cavity being neither possible nor desirable.

Quality of life and gender identity in females with congenital adrenal hyperplasia after genital restoration surgery: A single-center experience.

BACKGROUND: Legislation restricting surgical interventions in children with differences of sex development (DSD) has intensified debate about female genital restoration surgery (FGRS) in patients with congenital adrenal hyperplasia (CAH). Long-term patient-reported outcomes are needed regarding the optimal timing of surgery. OBJECTIVE: We aimed to assess health-related quality of life (HRQoL), gender identity, and family satisfaction regarding surgical timing and outcome in females with CAH following genital restoration surgery. STUDY DESIGN: Cross-sectional survey of CAH patients who underwent surgery between January 2007 to December 2016 at our institution. Validated instruments (KINDL questionnaire for HRQoL, Utrecht Gender Dysphoria Scale, UGDS) and structured telephone interviews were employed. RESULTS: Data on HRQoL was available for 25 patients (self- and/or parent-reported) out of 56 eligible patients (45% response rate). Median age at first surgery was 6 months (range: 3-137 months). Patients' age at time of participation ranged from 2 to 28 years. All had 21-hydroxylase deficiency (92% salt-wasting form) with Prader grades ranging from II-V. Wound dehiscence requiring secondary suturing occurred in 15% of patients with primary surgery at our center, while only one (4%) patient developed vaginal stenosis after early primary vaginoplasty. Two additional patients (8%) with prior outside surgery required vaginal revision after FGRS at age 12. HRQoL scores were comparable to healthy reference populations across most age groups. Children aged 3-6 and adolescents and young adults showed no significant difference from reference values, while children aged 7-13 showed a slight elevation. None of five patients ≥14 years demonstrated gender dysphoria (all UGDS scores <40, threshold ≥40). 14 patients and families were also interviewed by telephone. All preferred early surgical timing. No family expressed regret about the decision or preferred delayed surgery. DISCUSSION: This study provides validated intermediate-term patient- and parent-reported outcomes after FGRS in CAH. Key limitations include the small sample size, single-center design, and young age of most patients. Selection bias may exist, though participating families included those who underwent revision surgery. The absence of a non-operated comparison group reflects current clinical reality, as nearly all CAH patients with urogenital sinus underwent surgical correction. CONCLUSIONS: Females with CAH reported normal HRQoL and a comfortable female gender identity after early FGRS. The patients and their families expressed a preference for early surgery. However, there is need for longer-term follow-up to assess sexual function and reproductive outcomes as well comparison of outcomes with a non-operated group.

Nerve injury in revision total elbow arthroplasty: a systematic review and meta-analysis.

BACKGROUND: Revision total elbow arthroplasty (TEA) is technically demanding and carries a substantial risk of postoperative neurological complications because of scarring, altered anatomy, implant removal, and repeated humeral and ulnar exposure. The incidence, nerve distribution, and recovery profile of nerve injury after revision TEA remain incompletely defined. This study aimed to systematically review the literature to define the incidence, recovery profile, and risk factors for nerve injury after revision TEA. METHODS: A systematic review of the literature was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance. Thirteen retrospective case series were included, comprising 282 revision TEAs in 271 patients. Random-effects meta-analysis of proportions was undertaken where the data permitted. The primary outcome was postoperative nerve injury following revision TEA. Secondary outcomes included nerve type, recovery, secondary nerve-related procedures, infection, triceps insufficiency, metallosis, periprosthetic fracture, and re-revision. RESULTS: The pooled incidence of postoperative nerve injury was 22.3% (95% confidence interval [CI] 16.3 to 29.6; I2 = 34.6%). The crude incidence was 60 of 282 revisions (21.3%, 95% CI 16.6 to 26.5). The ulnar nerve was involved in 66.7% of all nerve injuries, the radial nerve in 31.7%, and the median nerve in 1.7%. No significant difference in pooled nerve-injury incidence was identified between studies published before 2010 and those published from 2010 onwards (22.9% vs. 21.4%, P = .837). Recovery reporting was heterogeneous; among injuries with numerically extractable outcomes, 85.4% improved partially or completely (95% CI 72.2 to 93.9). Secondary nerve-related procedures were reported in 7 studies. Pooled complication estimates were 10.2% for infection, 13.6% for triceps insufficiency, 25.5% for metallosis, 15.9% for periprosthetic fracture, and 14.0% for re-revision. CONCLUSIONS: Postoperative nerve injury is a common and clinically important complication of revision TEA, affecting approximately 1 in 5 cases. The ulnar nerve is most frequently involved, although radial nerve injury accounts for a substantial proportion of cases. Many neuropathies improve during follow-up, but persistent deficits and the need for secondary nerve-related procedures are not uncommon. Future studies should adopt standardized neurological definitions and reporting to improve comparability and guide preventive surgical strategies.

Multilevel Revision Percutaneous Vertebroplasty in Elderly Patients With Osteoporotic Thoracolumbar Fractures: A Retrospective Cohort Study.

PURPOSE: Vertebral compression fractures (VCFs) are common complications of osteoporosis in elderly patients. Percutaneous vertebroplasty (PVP) provides pain relief and functional improvement, but some patients require revision due to refracture, cement failure, or new symptomatic levels. While outcomes of primary and multilevel augmentation have been described, systematic data on multilevel revision PVP remain rare. The aim of this study was to evaluate pain relief, functional improvement, and perioperative safety after three- and four-level revision PVP in elderly patients with osteoporotic thoracolumbar fractures. METHODS: This retrospective, single-center cohort included patients aged 75-85 years who underwent revision PVP between August 2019 and November 2023. Eligible cases had a history of prior PVP and required repeat augmentation of three or four vertebral levels in a single session. Visual Analogue Scale (VAS) scores for pain and Oswestry Disability Index (ODI) for functional disability were recorded preoperatively and at 1-, 3-, 6-, and 12-month follow-up. RESULTS: Nine patients were analyzed. Revision involved three levels in five patients and four levels in four patients, with a mean interval of 14.1 months after the index procedure. Mean VAS improved from 8.3 ± 0.7 preoperatively to 3.2 ± 0.6 at 12 months (61% reduction, p < 0.01). ODI improved from 75.2% ± 3.4% to 26.9% ± 2.7% (64% reduction, p < 0.01). All patients exceeded the minimal clinically important difference thresholds. No perioperative complications such as cement leakage, neurological deficits, or pulmonary events were observed. CONCLUSION: Three- and four-level revision PVP provided significant pain relief and functional improvement in elderly patients with osteoporotic fractures, without increased complication rates. To our knowledge, this represents one of the first reports addressing this topic, suggesting it is an effective option in carefully selected patients.

[Surgical treatment method for nephroptosis].

A new method of nephropexy with an autograft by the upper pole to the diaphragm from intercostal lumbotomy is described. The method induces little injury, is technically simple and can be employed in those patients who do not need a revision or surgery on the renal pelvis, ureter or vascular pedicle. The method was used in operations on 45 patients. Good immediate and remote results were obtained.

Early tangential excision and immediate mesh autografting of deep dermal hand burns.

Thermal injuries to the hand constitute not only one of the most common burns, but one of the most difficult for the burn surgeon to treat. Early wound closure is mandatory if maximum functional return is to be attained and scarring minimized. Over the last three and one-half years, 60 patients with deep dermal dorsal hand and finger burns were treated by tangential excision and immediate mesh autografting. All patients were admitted to the hospital within 24 hours of injury and excision was performed between the third to the tenth post burn day. Operative technique consisted of sequential eschar excision using the Humby knife or Goulian-Weck dermatome until viable dermis was visible. Mesh autograft, ratio 1 to 1(1/2) without expansion, was applied. There was 100% graft take in all but four hands. Hand function with full range of motion returned by the tenth postoperative day. Complications were minor. Patient follow-up ranged from six months to three and one-half years. No patient has required subsequent surgery for scar revision or contracture release. Range of motion in all patients has been excellent and all patients have continued to maintain normal hand function. The cosmetic appearance has been good except for the early "mesh" appearance of the graft which has become less apparent with time. In summary, early tangential excision and immediate mesh autografting of deep dermal dorsal hand burns has fulfilled the following burn principles-preservation of tissue, prevention of wound infection, maintenance of function and early wound closure.

Cerebral commissurotomy for control of intractable seizures.

Cerebral commissurotomy or the "split-brain" procedure may be a valuable adjunct to anticonvulsants for the control of seizures in people whose epilepsy cannot be relieved by anticonvulsants alone, and who are not candidate for the standard methods of surgery. Corpus callosotomy, a revised form of the usual division of many commissures, is a safer operation and appears to be equally effective. The complex clinical aspects of cure and treatment are emphasized.

Antibiotic-impregnated bone graft to prevent infection after total hip arthroplasty (ABOGRAFT): protocol for a randomised, double-blind, placebo-controlled trial.

INTRODUCTION: Studies have shown promising results using bone graft as a carrier for local administration of antibiotics to reduce the risk of prosthetic joint infection (PJI). The objective of this clinical trial is to determine if tobramycin and vancomycin-impregnated bone graft is safe and effective in reducing the rate of PJI after total hip arthroplasty (THA). METHODS AND ANALYSIS: This study is an international, randomised, double-blinded, placebo-controlled clinical drug trial. Patients scheduled for THA (n=1100) requiring bone grafting (excluding revisions due to an ongoing infection) are randomised in a 1:1 ratio to prophylactic treatment with tobramycin and vancomycin or placebo-impregnated bone graft.The primary outcome is the time to reoperation due to infection or diagnosis of PJI, expressed as a relative risk difference between the two groups. A risk reduction of at least 50% is considered clinically relevant. Secondary outcomes are time to and reason for reoperation and implant revision, type of micro-organism and antibiotic susceptibility pattern within 2 and 5 years after surgery. Safety outcomes are the number of adverse events and revision rate due to aseptic loosening. The primary analysis will be performed using proportional hazard models. ETHICS AND DISSEMINATION: The study has been approved under the Clinical Trial Regulation No 536/2014 (EU CT; 2024-510921-25-00). Results will be published in open-access peer-reviewed journals and disseminated to patient organisations and the media, and de-identified individual participant data will be curated and shared on reasonable request in accordance with the Findability, Accessibility, Interoperability and Reuse principles, subject to the laws and regulations governing data protection in each participating country. TRIAL REGISTRATION NUMBER: NCT05169229.
