[Medial discoid meniscus in a pediatric patient. Case report and review of the literature].

Discoid meniscus is a congenital morphological variant of the meniscus, which tends to occur more frequently in its lateral form than in the medial form. This anomaly is characterized by central hypertrophy of the meniscus and a larger diameter than the normal meniscus, resulting in an abnormal shape and greater coverage of the tibial plateau. The clinical presentation of this condition varies depending on the stability of the meniscus.

Bilateral mirror hand: 2-year follow-up and literature review.

Introduction: Mirror hand syndrome is a very rare congenital deformity, also called cubital dimelia, characterized by the absence of the thumb, as well as the duplication of the fingers in a symmetrical image and, in some cases, with a duplication of the bones of the forearm.

Methods: The current treatment consists of a thumb reconstruction through thumb pollicization, although there are alternatives such as rotating osteotomy, syndactylization or conservative treatment. In this article we present the case of a girl with a non-classic bilateral mirror hand, the clinical and radiological findings, the bilateral surgical technique in two surgical times with six months of difference and two years follow-up.

[Installed Capacity Perception Survey for the Training of Residents Program in Orthopedics and Care Needs in Acute and Chronic Musculoskeletal Pathology in Mexico].

Introduction: It is essential that orthopaedic resident physicians be highly proficient in all aspects, considering the balance between supply, demand, need and context. Fundamental to identify the capacity and quality installed for their training in Mexico.

Material And Methods: Observational Study, transverse, non-probabilistic sampling-conglomerates, in two phases.

[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.

[Functional comparison in the treatment of Weber type B ankle fractures with suture device versus screw].

Background: Ten percent of all ankle fractures, 20% of the fractures treated surgically, and 1-18% of all sprains involve a syndesmosis injury. The methods used for reduction are metal or bioabsorbable syndesmotic set screws, direct repair, and sutures with or without buttons. The purpose of this study was to compare the clinical function of patients who sustained Weber B ankle fractures and were treated with the TightRope system or a syndesmotic set screw.

[Doxycycline as an adjuvant in postsurgical recovery of rotator cuff injuries. One-year follow-up].

Background: The severity and progression of rotator cuff tears have forced research on new treatment pathways such as metalloprotease inhibition, which has shown a reduction in healing time and improvement in the structure of collagen fibers.

Objective: To evaluate the use of doxycycline as a healing enhancer in rotator cuff tears after surgical treatment.

Material And Methods: 20 patients were included; they were divided into two groups, 10 with the use of doxycycline and 10 without it after arthroscopic repair with one-year follow-up.

Benefits of different postoperative treatments in patients undergoing knee arthroscopic debridement.

Purpose: To assess the effectiveness of viscosupplementation or platelet-rich plasma (PRP), compared to standard care, for pain relief after knee arthroscopic debridement in patients with meniscal pathology and osteoarthritis (OA), under normal clinical practice conditions.

Patients And Methods: We conducted a prospective, randomized, evaluator-blind, pilot study. After arthroscopy, patients were randomized to receive 1) five injections of HA1 (Suprahyal/Adant); 2) four injections of HA2 (Orthovisc); 3) three injections of HA3 (Synvisc); 4) a single injection of PRP (GPS™ II); or 5) standard care (control).

[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.

[Nontraumatic causes of bilateral avascular necrosis of the femoral head: link between hepatitis C and pegylated interferon].

Background: Avascular necrosis of the femoral head is a frequent condition in patients with a history of trauma. The major pathologic causes include vascular diseases, malignancies, hypercoagulability states, long-term steroid treatment, and some patients have a history of hepatitis C infection treated with pegylated interferon and ribavirin. Upon studying the behavior of the hepatitis C virus, Seef, Foster and Poynard found a hypercoagulability state that causes interruption of retinacular blood flow to the femoral head, without an increased incidence of osteonecrosis in this patient group.

Clinical efficacy of intra-articular injections in knee osteoarthritis: a prospective randomized study comparing hyaluronic acid and betamethasone.

Background: Osteoarthritis (OA) is the most common joint disease and leading cause of disability. Intra-articular (IA) administration of hyaluronic acid (HA) or corticosteroids (CS) have been previously studied, though using insufficient number of patients or short follow-up periods.

Objective: We evaluate HA and CS in patients with knee OA in terms of clinical efficacy over 12 months.

[Use of ischemia in total knee arthroplasty. Is there a difference?].

In Mexico, aging has become the daily routine of millions. Total Knee Arthroplasty is a procedure that is doing more and more with satisfactory results and survival of the implant up to 20 years in 90%. The tourniquet is a useful tool to the orthopedic surgeons to minimize blood loss and make the placement of implants easier, because it enhances the vision of the surgical field.

[Periprosthetic femur fractures. Experience at hospital Español de México with a 2-year follow-up].

Unlabelled: Periprosthetic fractures have had an increasing incidence in the past decades; their resolution is a difficult challenge even for the most experienced orthopedist surgeons. The Vancouver classification has contributed to a great extent to their better characterization and therapeutic guidance. The purpose of this paper is to make a review of the most recent advances on the topic and present our experience in the treatment of these fractures.

[Infection prevention during the perioperative period of primary hip and knee arthroplasty].

All surgical wounds are at risk of contamination by pathogens that may get in through the incision. The pre-surgical bath with a skin antiseptic agent 24 hours prior to the surgery, the timing of administration of prophylactic antibiotics, the choice and postoperative duration of the latter, the number of individuals within the OR and the movement inside it, the choice of chlorhexidine gluconate for its long duration against gram-positive and gram-negative organisms, and the use of a hair remover or an electric razor, all of the former concepts, some new and others not so new, led to performing an extensive bibliographic review with the idea of starting a standardization process that could change the way in which institutions operate when performing primary joint replacement, trying to reduce the annual infection rate and upgrade the quality of life of patients.

[Functional result in distal radius fractures. Comparison between the severity of the fracture, the treatment of choice and the baseline X-ray parameters].

Background: The AO classification has a prognostic value and assists physicians in the planning of fracture management. The X-ray data and the DASH questionnaire are used to assess the outcome of radial fractures. A trend towards open treatment, opposite to closed or percutaneous approaches, has been observed in the past ten years.

[Risk factors that have influence on acetabular erosion after a hip hemiarthroplasty in the treatment of subcapital fractures].

Objective: To determine the factors that influence in the erosion to acetabular in patients with later hemiprosthesis to a fracture of hip with a survival greater to 1 year.

Material And Methods: We made retrospective, comparative, descriptive and observational study, in patients who were used hemiarthroplasty for fracture of hip between January of 1997 and January of 2003. We obtained two groups of patients, those that had not undergone erosion and those that had erosion greater to 3 mm looked for similar characteristics, like age, pre passable cane or physical activity, overweight, sex, concomitances disease, degree of osteoporosis, function to cardiopulmonar, survival, size of prosthesis.
