[Restoring horizontal stability in III-V acromioclavicular dislocations by anatomic reconstruction of the coracoclavicular and acromioclavicular ligaments; surgical technique].

Introduction: dislocation of the acromioclavicular (AC) joint is a common injury seen in young adults. The objective is to describe a surgical technique that can restore the horizontal and vertical stability of the AC joint.

Material And Methods: we describe a surgical technique that can restore horizontal and vertical stability using an allograft for the anatomical reconstruction of the CC and AC ligaments, for AC grade III-V dislocations according to the Rockwood classification.

[Functional evaluation of the management of massive rotator cuff ruptures with the use of the subacromial balloo].

Introduction: Rotator cuff (MR) ruptures occur in more than 50% of patients over the age of 60, and can cause changes in normal shoulder biomechanics that can trigger rotator cuff tear arthropathy. There is currently no consensus on treatment for massive rotator cuff tears.

Objective: To evaluate the clinical and radiographic outcomes of subacromial balloon placement in these lesions.

Prevalence of Cyclomodulin-Positive and spp. Strains in Mexican Patients with Colon Diseases and Antimicrobial Resistance.

Colon diseases, such as colorectal cancer (CRC), are multifactor diseases that affect more than one million people per year; recently, the microbiota has been associated with an etiologic factor, specifically bacterial cyclomodulin positivity (CM). Unfortunately, there are no studies from Mexico that detail the presence of bacterial CM in patients with colon diseases. We therefore performed a comprehensive study to investigate the associations and prevalence of cyclomodulin-positive Diarrheagenic (DEC) non-DEC, and spp.

[Clinical and functional evaluation of patellofemoral resurfacing arthroplasties].

Background: The patellofemoral articulation is a biomechanical system susceptible to accelerated wear, affecting 25% of women. Currently, the treatment of osteoarthrosis Patelofermoral has resurfaced thanks to the creation of anatomical and biomechanically appropriate systems, with precise indications, earlier stages and with a better functional result.

Material And Methods: A cohort of 24 patients was analyzed during the period from 2010 to 2012, treated with a resurfacing prostheses HemiCap Patello Femoral Resurf (Franklin MA, USA), placed by 2 surgeons.

[Proximal humerus fractures: clinical assessment and functional outcome in patients with osteonecrosis of the humeral head].

Introduction: Fractures of the proximal humerus resulting in three or more fragments represent a high risk of necrosis. The former is the second most frequent site of necrosis, only after the femur, due to either traumatic or nontraumatic causes. The former are the most common, with an incidence rate of necrosis of 13-34% in fractures with more than four fragments.

[Minimally invasive treatment of mild and moderate hallux valgus].

Introduction: Our institution implemented a minimally-invasive surgery program that included a thorough preoperative assessment and planning to provide the patient with an appropriate correction of the radiographic parameters as well as esthetic satisfaction, together with a shorter hospital stay and less analgesic use.

Material And Methods: Retrospective, comparative, longitudinal and observational clinical trial. The study period was from January 2002 to December 2007; 40 patients with hallux valgus underwent minimally invasive surgery, 12 of them underwent bilateral surgery, for a total of 52 feet with hallux valgus; 100% of them were females.
