Flexor Tendon Injury: Avascular or Vascularized Region Suture? Biomechanical and Histopathological Study in Rabbits.

 The present study aims to analyze the mechanical and histopathological aspects of flexor tendon healing focusing on the suture placement site in a vascular or in an avascular region.  A total of 83 rabbits were submitted to a Kessler-type central suture in the vascularized tendon region (TN group) and in the avascular tendon region (FC group). The operated limb was immobilized for 3 weeks.

DIAGNOSIS AND MANAGEMENT OF PAGET'S DISEASE OF BONE - SERIES OF 8 CASES.

Paget's disease of bone is a chronic condition characterized by focal abnormalities of absorption and formation of bone, and it may lead to anatomical deformities, pain, fractures, and malignant transformation. It is common in the UK, Australia, New Zealand, and North America and has a strong hereditary component, affecting first- to third-degree relatives. The etiology remains unclear and treatment is based on control of the disease with bisphosphonates, with the aim of relieving symptoms and correcting laboratory abnormalities.

The effects of ethyl-2-cyanoacrylate and butyl-2-cyanoacrylate in the process of bone healing in rats. A controlled experimental study.

Objective: Synthetic adhesives are used by various medical specialties, especially in surgery; however, studies reporting their use in orthopedic practice are scarce. The aim of this study was to compare the results in using ethyl-2-cyanoacrylate or butyl-2-cyanoacrylate in the treatment of fractures in rats.

Methods: This was an experimental prospective controlled study in 90 rats, with humerus, femur, and tibia fractures, treated with ethyl-2-cyanoacrylate (SB group;  = 45) or butyl-2-cyanoacrylate (HA group;  = 45).

Epidemiology of pelvic ring fractures and injuries.

Objective: This study evaluated the pelvic ring fractures and injuries in patients admitted to and treated at this ward between August, 2012 and January, 2014.

Methods: 66 patients were submitted to treatment protocols according to their age, gender, skin color, injury mechanism, location of the trauma, classification of their injuries, emergency intervention, associated injuries, injured side of the body, treatment, and mortality. The most relevant data were classified according to statistic procedures, such as Goodman's association test.

Goldman score, but not Detsky or Lee indices, predicts mortality 6 months after hip fracture.

Background: Over the past years, several cardiac risk indices were evaluated and modified, including Goldman, Detsky, and Lee scores. The predictive capacity of these scores in hip fracture patients is lacking. Thus, our objective was to compare the Goldman, Detsky, and Lee scores as predictors of mortality in 6 months after hip fracture.

Associations of vitamin D deficiency with postoperative gait and mortality among patients with fractures of the proximal femur.

Objective: To assess whether serum vitamin D concentration is associated with gait status and mortality among patients with fractures of the proximal femur, six months after suffering the fracture.

Methods: Consecutive patients aged ≥65 years with fractures of the proximal femur, who were admitted to the orthopedics and traumatology ward of our service between January and December 2011, were prospectively evaluated. Clinical, radiological, epidemiological and laboratory analyses were performed, including vitamin D.

Informal caregivers of older people recovering from surgery for hip fractures caused by a fall: fall prevention.

The objectives of this study were to investigate the sociodemographic characteristics of informal caregivers of elderly persons who had undergone surgery for hip fractures caused by a fall, explore the level of caregiver's knowledge regarding fall prevention, and assess the relationship between this knowledge and the use of preventative measures in practice. This investigation consists of a cross-sectional study using nonprobability sampling methods conducted over a period of 12 months and involving 89 caregivers. The majority of caregivers were female (76.

Serum metalloproteinases 2 and 9 as predictors of gait status, pressure ulcer and mortality after hip fracture.

Introduction: The aim of this study is to evaluate the serum activity of metalloproteinases (MMPs) -2 and -9 as predictors of pressure ulcer (PU), gait status and mortality 6 months after hip fracture.

Methods: Eighty-seven patients over the age of 65 admitted to the orthopedic unit from January to December 2010 with hip fracture were prospectively evaluated. Upon admission, patient demographic information, including age, gender and concomitant diseases, was recorded.

Mini Nutritional Assessment predicts gait status and mortality 6 months after hip fracture.

The aim of the present study was to evaluate the Mini Nutritional Assessment (MNA), the Nutritional Risk Screening (NRS) 2002 and the American Society of Anesthesiologists Physical Status Score (ASA) as predictors of gait status and mortality 6 months after hip fracture. A total of eighty-eight consecutive patients over the age of 65 years with hip fracture admitted to an orthopaedic unit were prospectively evaluated. Within the first 72 h of admission, each patient's characteristics were recorded, and the MNA, the NRS 2002 and the ASA were performed.

EFFECT OF THE GRAFTING SECTION AREA ON ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION SURGERY - HISTOLOGICAL STUDY ON DOGS.

Objective: To correlate the initial grafting section area with the outcomes from anterior cruciate ligament (ACL) reconstruction surgery. Eight dogs underwent operations, divided into two groups according to graft size: Group A, 25% and Group B, 40% of the patellar ligament (PL) width.

Methods: After eight months, the dogs were sacrificed for macroscopic and histological analysis on the reconstructed ligaments.

Handgrip strength predicts pressure ulcers in patients with hip fractures.

Objective: Pressure ulcer (PU) is a frequent complication of hip fracture. Studies were carried out to identify the risk factors of PU development after hip fractures. The objective of the study was to determine the role of anthropometric measurements and handgrip strength as predictors of PUs in patients with hip fractures during their hospital stay and 30 d after discharge, which has not yet been established.

Modular hybrid total hip arthroplasty. Experimental study in dogs.

Background: This prospective experimental study evaluated the surgical procedure and results of modular hybrid total hip arthroplasty in dogs.

Methods: Ten skeletally mature healthy mongrel dogs with weights varying between 19 and 27 kg were used. Cemented modular femoral stems and uncemented porous-coated acetabular cups were employed.
