Total Hip Replacement in Developmental Hip Dysplasia: A Narrative Review.

The reconstruction of the hip joint in patients suffering from developmental hip dysplasia (DDH) is a demanding procedure and presents many challenges to the reconstructive surgeon. Higher rates of mechanical complications are present in this group of patients. The results of cemented and uncemented implants used in DDH patients are very promising, according to recent outcomes.

Acid suppression therapy, gastrointestinal bleeding and infection in acute pancreatitis - An international cohort study.

Background: Acid suppressing drugs (ASD) are generally used in acute pancreatitis (AP); however, large cohorts are not available to understand their efficiency and safety. Therefore, our aims were to evaluate the association between the administration of ASDs, the outcome of AP, the frequency of gastrointestinal (GI) bleeding and GI infection in patients with AP.

Methods: We initiated an international survey and performed retrospective data analysis on AP patients hospitalized between January 2013 and December 2018.

Wet Lab-Based Cataract Surgery Training Curriculum for the PGY 2/PGY 3 Ophthalmology Resident.

Introduction: Studies have shown that structured cataract surgery training curricula are beneficial for resident surgeons-in-training, yet nearly one-third of US training programs do not have one, and public dissemination of said curricula are lacking.

Methods: We created a microsurgical simulation center and accompanying structured training curriculum. Weekly lectures focused on the steps of cataract surgery, variations on technique, and complications.

Comparison of graft survival following penetrating keratoplasty and Descemet's stripping endothelial keratoplasty in eyes with a glaucoma drainage device.

Methods: A retrospective chart review was conducted on consecutive patients who underwent DSEK or PK. Inclusion criteria consisted of eyes with a diagnosis of glaucoma prior to corneal transplantation and ≥ 6 months of follow-up.

Individual patient data meta-analysis of organ failure in acute pancreatitis: protocol of the PANCREA II study.

Context: Organ failure is a major determinant of mortality in patients with acute pancreatitis. These patients usually require admission to high dependency or intensive care units and consume considerable health care resources. Given a low incidence rate of organ failure and a lack of large non-interventional studies in the field of acute pancreatitis, the characteristics of organ failure that influence outcomes of patients with acute pancreatitis remain largely unknown.

The use of postoperative slit-lamp optical coherence tomography to predict primary failure in descemet stripping automated endothelial keratoplasty.

Purpose: To determine if central donor lenticle thickness as measured by slit-lamp optical coherence tomography (SL OCT; Heidelberg Engineering, Heidelberg, Germany) is predictive of primary donor failure in patients undergoing Descemet stripping automated endothelial keratoplasty (DSAEK).

Design: Retrospective cross-sectional study.

Methods: Eighty-four patients who underwent DSAEK surgery by 2 surgeons (D.

High levels of synovial fluid osteoprotegerin (OPG) and increased serum ratio of receptor activator of nuclear factor-kappa B ligand (RANKL) to OPG correlate with disease severity in patients with primary knee osteoarthritis.

Objective: Evaluation of serum and synovial fluid OPG and sRANKL in 37 patients with primary knee osteoarthritis.

Design And Method: OPG and sRANKL were measured using ELISA.

Results: OPG, sRANKL and sRANKL/OPG were increased in osteoarthritis patients' serum.

Arthroscopic ACL reconstruction with Delta plasty: an innovative approach with hamstrings' transfer and double tibial tunnel.

We propose a new technique, with double bundle, double tibial tunnels with a bridge between them, using the hamstrings as auto-grafts, retaining either their central or peripheral attachment. A prospective series of 41 patients underwent primary reconstruction of the anterior cruciate ligament by one surgeon, arthroscopically and electronically assisted; 37 were men and 4 were women with a mean age of 24.7 years.

ACL reconstruction with semitendinosus tendon autograft without detachment of its tibial insertion: a histologic study in a rabbit model.

The purpose of this study was to evaluate the histologic changes that occur between 3 and 12 weeks in an intra-articular, semitendinosus autograft, which was harvested without detachment of its tibial insertion and was placed through tibial and femoral drill holes, in a rabbit model. About 30 New Zealand white rabbits underwent ACL replacement using a semitendinosus tendon autograft. The normal ACL was transected at its femoral and tibial insertions.

Estimation of radiation doses to patients and surgeons from various fluoroscopically guided orthopaedic surgeries.

In this study, a mathematical method was used to estimate the entrance surface dose (ESD) to the patient and the scattered dose (Ds) to the operating surgeon during various fluoroscopically guided surgical orthopaedic procedures. For 204 patients, the procedure type, the fluoroscopy time and the highest tube potential and current values observed during fluoroscopy were recorded. For the most often performed procedures (intramedullary nailing of peritrochanteric fractures, open reduction and internal fixation of malleolar fractures and intramedullary nailing of diaphyseal fractures of the femur), the respective mean fluoroscopy times were 3.

Comparison of fixation methods of double-bundle double-tibial tunnel ACL reconstruction and double-bundle single-tunnel technique.

An experimental study was conducted in order to evaluate biomechanical methods of single-bundle reconstruction in ACL and compare it with a new double-bundle double-tibial tunnel technique. Twenty-four porcine cadaver knees, divided into 4 groups of 6 knees each and 48 proper extensors of the fourth toe tendons, were used for the fixation techniques. In groups A and B, a double-bundle technique with a single femoral and tibial tunnel was used, fixed to a femoral and tibial post with screws and with buttons, respectively.

ACL reconstruction and the implication of its tibial attachment for stability of the joint: anthropometric and biomechanical study.

The planar topography of the anterior cruciate ligament (ACL) insertion was investigated and correlated to the use of the double-bundle/double tibial tunnel ACL reconstruction technique within the ACL tibial insertion area. The anteroposterior and mediolateral length of the tibial ACL attachment and the distances of the tibial insertion area from the anterior and posterior tibial borders were measured and the stability of the joint was tested using the double-bundle/double tibial tunnel ACL reconstruction technique. The anteroposterior length, 19.

Cementless LCS rotating-platform knee arthroplasty in patients over 60 years without patella replacement: a mid-term clinical-outcome study.

Background: The aim of this prospective paper is to present the results of a cementless LCS rotating-platform artificial knee design without resurfacing of the patella in patients over 60 years of age.

Material/methods: In this prospective series, 234 patients were included with 251 knees. The LCS rotating-platform uncemented design was used in all cases, without replacement of the patella.

Photoelastic study of the internal and contact stresses on the knee joint before and after osteotomy.

Introduction: The treatment of knee osteoarthrosis represents a difficult task. Osteotomy is one of the treatment regimes which, in earlier times, was the only surgical procedure giving reliable mid-term results. The improvement was attributed either to the changing of the acting forces or to the so-called biological factor.

Isolated meniscal repair in the avascular area.

The authors present the results of a prospective cohort study carried out in young patients, to evaluate the outcome of meniscal repair in the avascular region of the meniscus. Forty five patients underwent either open (23 patients) or arthroscopic repair (22 patients) between 1982 and 1992. Seventeen men and eight women were included in the present study; their ages at the time of admission ranged from 16 to 27 years.

Early weight bearing after posterior malleolar fractures: an experimental and prospective clinical study.

The distribution of axial load to the lower end of the tibia at different positions of the ankle joint for the anterior, middle, and posterior part of the joint was studied in both photoelastic models and fractured ankle joints in cadaveric specimens. Synthetic models were used to simulate both normal ankle joints and ankles with fractures of the posterior lip of the tibia. Tests were performed with the ankle at dorsiflexed, neutral-flexed, and plantarflexed positions of the ankle joint.
