Comparative analysis of the quality of the cement mantle in hip hemiarthroplasty after femoral neck fracture between three different surgical approaches: a single-center retrospective observational study.

Purpose: Achieving the initial stability of implants is necessary for hip hemiarthroplasty (HHA), especially in elderly patients, and this can be achieved with a cement mantle of quality. The direct anterior approach (DAA) for HHA lately has shown positive results. However, evidence is lacking of HHA in elderly patients with osteoporosis after femoral neck fracture (FNF).

Challenges in implementing a total hip arthroplasty program in a developing country: Our experience at Monkole Hospital in the Democratic Republic of Congo.

Background And Objectives: Total hip arthroplasty (THA) is an effective surgery for treating hip osteoarthritis, but access is limited in Sub-Saharan Africa due to multiple challenges. This article describes the implementation of a THA program at Monkole Hospital in the Democratic Republic of Congo, focusing on the technical challenges and surgical complications. The objective is to share our experience to assist other professionals and organizations in similar settings.

[Translated article] Validation of the Spanish version of the modified Harris score.

Background And Objectives: Modified Harris Hip Score (HHS) is one of the most used scales in the assessment of patients with hip pathology. Although a Spanish cross-cultural adaptation has been recently published, there are many studies supporting its validity yet. Therefore, the aim of this study is to validate the newly adapted Spanish version of the HHS (ES-EHM), comparing it with the WOMAC scale.

From second webspace syndrome to second cross over toe: Clinical and radiological findings following Weil osteotomy with no soft tissue procedure.

Background: The second webspace syndrome (SWS) refers to the progressive divergence between 2nd and 3rd toes associated with pain at the second intermetatarsal space that can be confused with Morton's neuroma and treated as such without considering the underlying deformity. There is yet no consensus regarding the best treatment, from isolated soft tissue or bony procedures or a combination of both. The objective of this study was to describe the clinical characteristics of the disease, as well as to evaluate the radiological outcomes of patients with SWS treated with open Weil's osteotomy or distal metatarsal minimal invasive osteotomy (DMMO) of the second metatarsal, with main emphasis on medialization of the head in the anteroposterior plane in either procedure.

Iliopsoas impingement after total hip arthroplasty: Does the CT-scan have any role? Our Algorithm proposal.

Introduction: The first surgical option considered in managing iliopsoas impingement following THA is endoscopic/arthroscopic iliopsoas tenotomy, because of its low risk and minimal invasiveness. Acetabular revision is a much more aggressive surgery, recommended only in cases of substantial cup malposition. However, there are no clear indications for this procedure.

Differential effects of high-altitude exposure on markers of oxidative stress, antioxidant capacity, and iron profiles.

High-altitude (HA) exposure may stimulate significant physiological and molecular changes, resulting in HA-related illnesses. HA may impact oxidative stress, antioxidant capacity, and iron homeostasis, yet it is unclear how both repeated exposure and HA acclimatization may modulate such effects. Therefore, we assessed the effects of weeklong repeated daily HA exposure (2,900-5,050 m) in altitude-naïve individuals ( = 21 individuals, 13 females, mean ± SD, 25.

Cross-cultural adaptation for the Spanish population of the modified Harris score for functional and symptomatic hip joint assessment.

Background And Objectives: The modified Harris hip score, is one of the most widely used scales for the functional assessment of hip pathology of the patients. However, there is no cross-cultural adaptation for the Spanish society. Therefore, this study aims to obtain a cross-cultural adaptation of the modified Harris hip score for the Spanish population.

Comparison Between Pressure Swing Adsorption and Liquid Oxygen Enrichment Techniques in the Atacama Large Millimeter/Submillimeter Array Facility at the Chajnantor Plateau (5,050 m).

The Chilean workforce has over 200,000 people that are intermittently exposed to altitudes over 4,000 m. In 2012, the Ministry of Health provided a technical guide for high-altitude workers that included a series of actions to mitigate the effects of hypoxia. Previous studies have shown the positive effect of oxygen enrichment at high altitudes.

Restoring hip biomechanics during the learning curve of a novice surgeon: Direct anterior approach vs posterior approach.

Introduction: It remains controversial whether the direct anterior approach (DAA) or the posterior approach (PA) allows better restoration of hip biomechanics after total hip arthroplasty (THA). Besides, it is not certain which approach is best for a novice surgeon to avoid implant malposition, neither during the learning curve nor once the curve plateau has been reached.

Methods: We performed a retrospective cohort study of THAs operated on between 2014 and 2019 by a single novice surgeon (DAA, n = 187; PA, n = 184).

A comparative of a single novice surgeon's direct anterior approach and posterior approach learning curves in total hip arthroplasty: a retrospective cohort study.

Introduction: The purpose of the present study was to compare a novice surgeon's learning curves with the direct anterior approach and posterior approach in total hip arthroplasty.

Methods: A consecutive series of 376 total hip arthroplasties performed from November 2014 to September 2019 in a level-one healthcare center by a single surgeon (V.B) were retrospectively studied.

Checkrein deformity: a case report of two patients with hallux deformity and pain following mandibular reconstruction in oral cancer treatment.

Background: Checkrein deformity is an uncommon disease with a well-described etiology. It is characterized by a dynamic deformity of the hallux or great toe. We report two cases of checkrein deformity due a fibular graft harvesting in two patients with a mandibular bone defect secondary to an oral cancer treatment.

Cognitive Effects of Repeated Acute Exposure to Very High Altitude Among Altitude-Experienced Workers at 5050 m.

We investigated altitude effects on different cognitive domains among perennial shift-workers at the Atacama Large Millimeter/submillimeter Array Observatory (5050 m), Chile. Twenty healthy male workers were recruited and assigned to either a moderate-altitude first ( group, : 2900 m and : 5050 m) or to a high-altitude first ( group, : 5050 m and : 2900 m). was conducted at the beginning and at the end of the shift-work week.

The Effect of Oxygen Enrichment on Cardiorespiratory and Neuropsychological Responses in Workers With Chronic Intermittent Exposure to High Altitude (ALMA, 5,050 m).

It is estimated that labor activity at high altitudes in Chile will increase from 60,000 to 120,000 workers by the year 2020. Oxygenation of spaces improves the quality of life for workers at high geographic altitudes (<5,000 m). The aim of this study was to determine the effect of a mobile oxygen module system on cardiorespiratory and neuropsychological performance in a population of workers from Atacama Large Millimeter/submillimeter Array (ALMA, 5,050 m) radiotelescope in the Chajnantor Valley, Chile.

Age-related arrhythmogenesis on ascent and descent: "autonomic conflicts" on hypoxia/reoxygenation at high altitude?

Purpose: To discern whether arrhythmogenesis at high-altitude (HA) may differ depending on ascent or descent, as well as on age.

Methods: Male subjects (37.9±12.

[Malignant histiocytosis in children].

A case of malignant histiocytosis in a two year old boy is reported. His main clinical features were fever, lymphadenopathy, hepatomegaly and splenomegaly. Lymph node biopsy showed a sinusoidal type of lymph node infiltration, histiocytes of malignant aspect and erythrophagocytosis.
