Abstract

Background
IOL power calculation is now a crucial step in cataract surgeries especially after development of phacoemulsification and intraocular lens as the aim of cataract surgery now is no longer media opacity treatment only but also correction of refraction errors. That’s why new devices with new techniques as Sirius Scheimpflung tomography which combines both Scheimpflug camera and placido disk corneal topography and uses ray tracing method and artificial intelligence in IOL power calculation was evolved to increase the accuracy of IOL power calculation.

Purpose
Compare the accuracy of predictability of postoperative refraction of Sirius + (CSO, Italy) Scheimpflung tomography with Nidek optical biometer AL-scan (Nidek CO., Tokyo, Japan).

Materials and Methods
Forty eyes of twenty eight patients were enrolled in this prospective cohort comparative study, which was performed at the Department of Ophthalmology of Ain Shams University Hospitals during the period between April 2023 till December 2023. The patients underwent complete ophthalmological examination and did biometry with both Sirius tomography and Nidek optical biometer, then postoperative refraction was done using autoref (Shin-Nippon accuref 8001, Japan. Comparison between predicted refraction by Sirius and Nidek with postoperative refraction was done.

Results
There was statistically significant difference between the Nidek postoperative predictive refraction and the postoperative spherical equivalent of the studied patients with p-value &lt; 0.05, while there was statistically non-significant difference between the Sirius postoperative predictive refraction and the postoperative spherical equivalent with p-value &gt; 0.05.

Conclusion
Sirius tomography is more accurate in IOL power calculation than Nidek optical biometry.

Published: November 2024

Abstract

Background
Cataract is a common eye disorder that, if left untreated, can result in significant impairment of mental health, quality of life, function, and dangerous falls. Presbyopia correction during cataract surgery is becoming more common, and patients are requesting it more.

Objective
To assess the effect of extended depth of focus for monofocal IOLs on the unaided intermediate distance visual acuity and to compare between AcrySof®IQ clear IOL and TECNIS EyhanceTMIOL results in contrast sensitivity.

Methods
The study was Prospective cohort study and will be conducted at Ain Shams hospitals by donations, after the approval of the research ethical committee, between November 2022 to June 2023, Follow up the patient three times (first day after operation, one month after operation and 6 month after operation).

Results
Typical monofocal aspheric IOLs have been designed with negative spherical aberration (SA) to compensate for the human cornea's average positive SA as ACRYSOF™ IQ CLEAR SA60WF that we used in this study. Results of this study revealed after six month postoperative, we can see there was no big difference in best corrected far vision between the two IOLs or in contrast sensitivity, but we can notice better unaided intermediate visual acuity with Eyhance IOL.

Conclusion
The results from this study demonstrated the safety and effectiveness of the enhanced monofocal IOL, Model ICB00, and to show evidence of an improvement in intermediate vision with comparable distance vision and dysphotopsia profile similar to a standard monofocal AcrySof™ IQ Aspheric IOL Model SA60WF. As a result, the enhanced monofocal IOL will provide patients undergoing cataract surgery with an alternative to standard monofocal IOLs, which might offer improved functional performance in daily life.

Published: November 2024

Abstract

Background
Successful reconstruction of contracted sockets requires the implantation of an allograft or auto graft. Amniotic membrane and oral mucosa are still the most commonly used substitutes for reconstruction of large conjunctival defects in contracted eye sockets.

Aim of the Work
To conduct a systematic review and meta-analysis estimating the efficacy of amniotic membrane versus mucous membrane grafting in reconstruction of mild to moderate contracted eye sockets.

Materials and Methods
A comprehensive literature search was conducted across the following databases: Google scholar, PubMed, MEDS, web of science, EMBASE and Cochrane Library for published studies from the 1st of January 1990 to the 1st of December 2022. According to the inclusion and exclusion criteria, four studies (published between 2006 and 2018) were included in the presented meta-analysis; they included 72 patients with mild to moderate contracted eye sockets.

Results
This study demonstrated a higher average upper fornix (UF) depth among patients in amniotic membrane grafting (AMG) group as compared to patients in mucous membrane grafting (MMG) group with a difference of + 1.08 mm in favor of AMG group, the overall effect is border line significant P = 0.06. Also, a higher average lower fornix (LF) depth was found among patients in AMG group compared to patients in MMG group with a mean difference of + 0.99 mm in favor of AMG group, the overall effect is highly statistically significant P &lt; 0.0001. The average socket volume was higher in AMG group in comparison to patients in MMG group with a mean difference of + 0.14 mm in favor of AMG group, and the overall effect is border line significant P = 0.05. A lower percentage of complications was found in AMG group (21.6%) as compared to MMG group (26%) with no significant difference statistically; P value &gt;0.05.

Conclusion
The presented analytical study revealed that AMG achieves superior clinical results in comparison to the MMG in reconstruction of mild to moderate cases of contracted sockets regarding socket volume, and upper and lower forniceal widening. It also carries lower risk of complications.

Abstract

Background
Glaucoma is the second leading cause of irreversible blindness worldwide. It affects the nerve fiber layer which forms the optic nerve. Many patients discover glaucoma accidently when they’re doing regular checkups. Glaucoma may have no specific symptoms until the advanced stages and it can be diagnosed by measuring intra ocular pressure, optic disc evaluation and visual field examination. The present work aims at evaluation of different methods in optic disc examination in glaucoma patients to detect their efficacy in diagnosis and follow up.

Purpose
To evaluate the agreement among slit lamp biomicroscopy, stereoscopic fundus photography and OCT in glaucomatous patients regarding Disc area, Cup area and vertical cup disc ratio (VCDR).

Material and Methods
14 known glaucomatous patients were included in this cross-sectional observational descriptive. All patients under went slit lamp biomicroscopy examination by using +90 lens, stereoscopic fundus photography to obtain 3D image for optic disc and using computerized program to measure the optic disc parameters and Optical Coherence Tomography for the optic disc.

Results
Comparing each examiner values measured on stereoscopic fundus image in comparison with OCT. Examiner one have a moderate reliability regarding disc area, cup area and VCDR with ICC 0.67, 0.67 and 0.50 and P values 0.68, 0.61 and 0.01 respectively and examiner two have a moderate reliability regarding disc area, cup area and VCDR with ICC 0.66, 0.63 and 0.54 and P values 0.16, 0.69 and 0.03 respectively and examiner 3 has a moderate reliability regarding disc area and VCDR with ICC 0.65, 0.71 and P value 0.69, 0.07 respectively while a good reliability for cup area with ICC 0.82 and P value 0.02. Comparing values obtained by slit lamp using +90 lens and stereoscopic fundus photography regarding VCDR there is a moderate reliability with ICC 0.50 and P value 0.06 for examiner one only.

Authors: Diab Abdelrahman Ahmed Elsayed , Elganzory Ibrahim Mostafa , Sallam Haitham Emad Elden Hafez 
Published: November 2024

Abstract

Background
Various epidemiological studies have revealed that the incidence of acetabular fracture is increasing rapidly. The most critical step in the treatment of displaced acetabular fracture is the anatomical reduction of the articular surface and stable fixation as well as the use of appropriate surgical approach to achieve good clinical outcomes.

Aim of the Work
to perform a systematic review to compare between modified Stoppa approach and ilioinguinal approach regarding Blood loss, Operative time and Complications in pelvi-acetablar fractures

Patients and Methods
On June 2022, we systematically searched the PubMed, the Web of Science, and the Cochrane Library electronic databases for relevant articles. The following terms were used for our search: acetabular fracture, approach and (comparison or versus Stoppa Approach, Ilioinguinal Approach, Pelvic fractures, Acetabular fractures and Pelvi- Acetabular Fractures.). We also checked the reference lists in the retrieved articles in order to include additional studies that met the criteria but had not been identified by the electronic search. All studies identified were individually assessed for inclusion in our study.

Results
That operative time was significantly shorter with the MS approach than with the IL approach and this was statistically significant. The main result of our results was post operative outcome was significantly better with the MS approach than the IL approach. In our study, there was no significant difference between the two approaches as regards postoperative complications except in nerve injury.

Conclusion
Our findings reveal that both the Modified Stoppa Approach and the Ilioinguinal Approach are viable options for the surgical management of pelvi-acetabular fractures. The choice between these two approaches should be tailored to individual patient factors, specific fracture patterns, and surgeon expertise. While the Modified Stoppa Approach may be associated with a lower incidence of certain complications, such as neurovascular injuries, the Ilioinguinal Approach provides better access to specific fracture types and may be favored in cases of associated anterior column or anterior wall involvement. Additionally, functional outcomes and long-term patient satisfaction appear to be comparable between the two approaches.

Authors: Al Masry Ayman Mohammed , El Mowafi Mohamed Ahmed , Mohammed Abdelrahman Gamal 
Published: November 2024

Abstract

Background
Periacetabular oncological lesions may present in various areas of the acetabulum and be of varying size. Many types of reconstruction are available for their treatment to deal with defects after tumor resection but which technique is optimal remains controversial.

Objective
To evaluate different methods and approaches of acetabular metallergic reconstruction after periacetabular tumor resection as regards surgical techniques, clinical, functional, oncological outcomes and possible complications.

Methods
This systematic review and meta-analysis study included twenty five studies with a total of 846 cases to evaluate different methods of acetabular reconstruction after periacetabular tumor resection as regards surgical techniques, clinical, functional, oncological outcomes and possible complications. We conducted a systematic review of literature in different databases and with pre-specified eligibility criteria and according to Cochrane’s handbook of systematic review guidelines in screening, we concluded sixteen different studies to be included in our study. Data were obtained from text, tables, figures, and supplementary data. We focused on the following outcome measures: operative time, blood loss, postoperative complication, MSTS score, and implant survival rate. Risk of bias assessment was done according to GRADE guidelines to every study using Cochrane’s risk of bias tool.

Results
Regarding implant survival analysis, the current study detected that first year survival rate was as following; constrained-type hip tumor prosthesis was 91%, ice-cream cone prosthesis was 72% and for Iliac Stem prosthesis first year survival rate was 90%. 3-year survival rate, the present study pooled result for the odds of three year survival for hemipelvic endoprosthesis (OR = 0.78, 95%CI = [0.71, 0.88], I 2 = 59.7%, P value=0.04), three year survival rate for the rest was as following; constrained-type hip tumor prosthesis was 62%, ice-cream cone prosthesis was 58% and for Iliac Stem prosthesis first year survival rate was 70%. 5 year survival, best results were achieved by Compound osteosynthesis 93.3 % followed by LUMiC ndoprosthetic 83%.

Conclusion
The choice of the best method of reconstruction after periacetabular tumor resection should be tailored according to each case, depending on many factors such as, age, daily activity, general condition, tumor type and human size. However, hemipelvic endoprothesis and ice cream cone prothesis may be the treatment of choice in young active patients, while in elderly with multiple comorbidities 3D printing represent the best option according to its availability
Femoral versus Acetabular Containment Procedures in Perthes Disease: A Systematic Review and Meta-analysis
Authors: Ahmed Adel Alaa Refai , Mahran Mahmoud A , Baraka Mostafa M 
Published: November 2024

Abstract

Background
Perthes disease is a rare childhood condition that affects the hip. It occurs when the blood supply to the rounded head of femur is temporarily disrupted. Without an adequate blood supply, the bone cells die, a process called avascular necrosis. There is limited data about surgical options in treatment of Perthes disease. The authors conducted this systematic review and meta-analysis to compare between femoral versus acetabular containment in the management of Perthes disease in terms of efficacy and complications, however there is a debate about the ideal way of treatment in Perthes disease.

Objective
To compare between femoral varus and acetabular containment osteotomies in children with Perthes disease, regarding the efficacy, long-term outcomes and complications.

Methods
This systematic review and meta-analysis examined studies that compared FVO and Pelvic Osteotomy. The authors searched the Medline database via PubMed, EMBASE, and Cochrane Library for studies published between 2012 and 2022.

Results
A total of 1051 patients were analyzed for different procedures, including 429 patients in the pelvic arm, 459 patients in FVO arm, and 163 patients in the combined arm. The number of hips included in the current analysis was 1069 hips, including 437 in pelvic arm, 469 in FVO arm, and 163 in the combined arm. The mean age for the included patients was 9.5±7.74 years, with 859 (81.8%) males and 192 (18.2%) females. There was an apparent predominance in males vs. females in all arms. The mean follow-up of the included studies was 8.6±8.32 years. We compared between the three procedures clinically, radiographic and complications. (FVO: Femoral varus osteotomy).

Conclusion
Femoral varus osteotomy and Pelvic osteotomy have shown comparable clinical and radiological improvement in treatment of perthes disease. The FVO group has shown higher rate than pelvic or combined osteotomies regarding post-operative arthritis and decrease range of motion. The pelvic group has shown higher rate than FVO and combined osteotomies regarding post-operative impingement and leg length discrepancy. There was no significant difference between the pelvic, femoral and combined osteotomies regarding range of motion, Trendelenberg, limping, post-operative pain and secondary knee deformity. In summary, this review provides evidence that femoral and pelvic osteotomies are safe, effective methods in treatment.

Authors: Abou Seif Salah Abdel Gawad , Beshry Shady Samir El , Mounir Ayman Fathy , Galhoum Ahmed El Sayed Yosef 
Published: November 2024

Abstract

Background
Intraarticular fractures of the distal tibia is a challenging condition that requires surgical intervention in the majority of cases. Due to the nature of the injury and the vulnerable soft tissue envelope around the ankle and distal tibia, skin necrosis and soft tissue devitalization is a major concern. Open reduction and internal fixation offers a reliable method to restore the anatomy and to maintain the length of the limb, however, in many cases this approach might not be ideal and get complicated with skin sloughing and necrosis.

Aim of the Work
To evaluate the role of ring external fixator in the management of intra articular fractures of the tibial plafond and to assess the functional outcome and patient satisfaction following this procedure.

Patients and Methods
Ring External fixation with minimally invasive AO screws offer another reliable alternative that achieves the reduction and allows for soft tissue healing. In this study we prospectively treated 30 patients who presented with distal tibia intraarticular fractures using Ilizarov frames in combination of minimally invasive AO screws. The minimum follow up was 4 years and the outcome was assessed radiologically and functionally using AOFAS scores.

Results
The results showed that 96% of the patients achieved bony union and satisfactory functional scores. There was no incidence of skin or soft tissue necrosis apart from superficial pin tract infection that was treated successfully. Three patients developed ankle OA four years post operatively that was managed later with ankle fusion. One patient experienced non union and was managed with pantalar ankle fusion. The Mean AOFAS scores at 12 months and 48 months were 76.2±8 Range (59-89) and 75.1±11 Range (37-91) respectively. In addition, we found that smokers within the study group had significantly lower AOFAS scores than non-smokers.

Conclusion
Ilizarov external fixation with minimally invasive AO screws is considered a reliable and safe way to manage intraarticular fractures of the distal tibia that respects the soft tissues and produce good functional results.
Superior Capsular Reconstruction Versus Reversed Total Shoulder Arthroplasty in Management of Massive Irreparable Rotator Cuff Tear: A Systematic Review and Meta-analysis
Authors: Mahmoud Ali Gamal Ali , Ghazaly Sherif Ahmed El , Kotb Ahmed Mostafa 
Published: November 2024

Abstract

Background
rotator cuff pathology is one of the most common sources of shoulder disability and among the prevalent conditions treated by orthopaedic surgeons. Irreparable rotator cuff tear is generally large tear (in both anterior-posterior and medial-lateral dimensions) and retracted with poor attenuated tissue quality, muscular atrophy and fatty infiltiration.

Aim of the Work
to conduct a systematic review about superior capsular reconstruction Versus reversed total shoulder arthroplasty in treatment of massive irreparable rotator cuff tears aiming to reach a conclusion regarding superiority of one technique over the other. We may then present recommendations to orthopaedic surgeons to facilitate decision-making when approaching such cases.

Patients and Methods
this systematic review will be performed following the preferred reporting items for systematic reviews meta-analysis (Prisma). Six guided items and check list to answer the question of: comparison study between superior capsular reconstruction and reversed total shoulder arthroplasty in treatment of massive irreparable rotator cuff tears. Patients with irreparable rotator cuff tear of both gender and patients older than 18 years.

Results
all outcomes showed improvement in all studies either clinically and radiologically, also all studies had low complications rate as the following with variation of significance and heterogenicity between each group of studies. The mean age of patients underwent SCR was 64.7 ± 5.89 years, while for patients underwent RTSA; the mean age was 68.1 ± 22.18 years with metanalysis between the two groups; showing significant difference between them (p- value:0.0001) as the SCR operation was decided for age group younger than patients underwent RTSA with mean difference 5.24 (95% CI [ 2.57, 7.9]) years. Both SCR and RTSA showed significant improvement post operatively with functional scores and in active range of motion with no significant difference between the two operations except with JOA score and Constant score; both showed difference between the two groups favoring SCR over RTSA, (p-value:0.001) with JOA and (p-value:0.04) with constant score.

Conclusion
based on the evidence presented, both SCR and RTSA showed significant improvement in post-operative outcome measures in management of MIRCTs. All outcome measures showed comparable results with both SCR and RTSA except in JOA score and constant score, both showed significant improvement favoring RTSA. RTSA was the preferred choice for elderly patients with higher grade of glenohumeral arthritis and it was the most common revision surgery after failed SCR. It is preferred to mention SCR as the joint preserving surgical technique and that is why it would be the preferred technique in young age patients with relative lower grades of glenohumeral arthritis.
