Analysis of the distribution of mechanical load on the plate and lateral hinge of a valgus-producing open wedge high tibial osteotomy during weight-bearing by simulating consolidation. Finite element study.

Introduction: High tibial osteotomy (HTO) is indicated for managing isolated medial knee osteoarthritis in a young patient with a metaphyseal deformity of the proximal tibia. In a medial open-wedge HTO, maintaining the integrity of the hinge is crucial for consolidation and preservation of the correction. Based on a validated model and preliminary results, the objective of this work was to measure and monitor the distribution of mechanical load on a locking fixation plate and the lateral hinge of an HTO using a finite element (FE) model during different phases of consolidation evolution, simulating single leg weightbearing.

Hip Labral Repair versus Reconstruction: Meta-analysis.

The purpose of this meta-analysis is to compare the postoperative outcomes and complications of labral repair with those of labral reconstruction. An electronic search strategy was conducted from 1986 until August 2023 using the following databases: PubMed, Cochrane, and Google Scholar (pages 1-20). The primary objectives included the postoperative clinical outcomes determined by the number of patients who reached minimal clinical important difference (MCID) on the visual analog scale (VAS), modified Harris hip score (mHHS), Hip Outcome Score-Sports Subscale (HOS-SS), Hip Outcome Score-Activities of Daily Life (HOS-ADL), and International Hip Outcome Tool-12 (iHOT-12).

Intraoperative live measurement of femoral head size for acetabular cup sizing: simple, accurate, and green!

Purpose: Templating is the first step in achieving a successful total hip arthroplasty. We hypothesize that native head size is highly correlated with implanted cup size. Therefore, the purpose of this study is to look for a correlation between sizes of the intra-operative measurement of the femoral head and the implanted cup.

Analysis of systemic risk factors between diabetic/vascular patients having primary lower limb amputations and re-amputations.

: Patients with diabetes mellitus (DM) are known to be predisposed to many complications in the lower extremities such as neuropathy, peripheral artery disease (PAD) and infection. Diabetic foot ulcers are complications of diabetes that can lead to lower extremity amputations, re-amputations and high mortality rates.: The aim of this study is to evaluate the risk factors associated with higher re-amputation rates in diabetic foot disease.

Beirut massive blast explosion: A unique injury pattern of the wounded population.

Introduction: On August 4, 2020, a massive explosion of a warehouse holding 2,700 metric tons of ammonium nitrate took place in the port of Beirut, Lebanon. This incident, which is considered as one of the largest industrial disasters lead to the death of at least 220 people and more than 6000 injuries. Hospitals near the blast were damaged significantly which made it difficult to treat injured patients.

Major acetabular defects: outcomes of first revision total hip arthroplasty using Kerboull cross-plate with allograft and cemented dual mobility cup at a maximum follow-up of fourteen years.

Background: The use of dual mobility cups (DMC) has been shown to reduce hip instability after revision surgery. For severe acetabular bone loss, reconstruction with a Kerboull cross-plate and bone allograft would contribute to restoring native hip position and bone stock. Only two papers reported on the combination of Kerboull cross-plate with bone allograft and cemented DMC in revision total hip arthroplasty (THA).

Amputation and mortality frequencies associated with diabetic Charcot foot arthropathy: a meta-analysis.

Background: Five-year mortality and amputation frequencies after new-onset diabetic ulceration have been reported up to 55% and 74%, respectively. for patients with lower-extremity amputation. Following Charcot arthropathy, these frequencies were reported with wide variations.

Nerve transfers in the upper extremity: A review.

Injury of the brachial plexus and peripheral nerve often result in significant upper extremity dysfunction and disability. Nerve transfers are replacing other techniques as the gold standard for brachial plexus and other proximal peripheral nerve injuries. These transfers require an intimate knowledge of nerve topography, a technically demanding Intraneural dissection and require extensive physical therapy for retraining.

Internal fixation or primary arthrodesis for Lisfranc complex joint injuries? A meta-analysis of comparative studies.

Purpose: Though uncommon, Lisfranc complex joint injuries constitute a therapeutic challenge. Two surgical methods are commonly used to treat such injuries: open reduction and internal fixation (ORIF) and primary arthrodesis (PA). The aim of this meta-analysis is to look for significant differences in the outcomes between these two techniques.
