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. The instrument has 8 domains, 57 variables and 4,867 items. 60 graduate professors of 20 states, 50 hospital sites, 22 university programs., Results: 1,038 years of experience (collective intelligence), 17 years of experience/teacher (01 to 50 years). Identified: acute pathology 30 (2 to 90%), chronic pathology 30 (5 to 96%), patients 15 years, 10 (3 to 30%), patients between 15 and 65 years, 47 (2 to 78%), patients 65 years, 20 (2 to 60%), number of beds/seat 20 (2 to 510), number of clinics 3 (1 to 48), number of surgical procedures/headquarters per year at the national level, was 960 (50 to 24,650). The national average per resident doctor is 362 surgeries/year with 1,450 surgical times/year., Conclusions: The needs and resources for the training of physicians specializing in orthopedics/traumatology are highly heterogeneous, so it should be adapted to the epidemiological needs of the region of influence, in an area of epidemiological transition. 62.2% expressed not having or have bad academic and scientific infrastructure at its headquarters, more than 50% without rotation overseas and 90% without regular scientific production.

Unlabelled: According to the statistics, long bone fractures in children are caused by high-energy mechanisms and they are the most frequent ones in the orthopedic practice. The advantage of reducing these fractures with elastic titanium nails and three buttress points is that neither the blood supply nor the physis are injured., Material and Methods: Twenty-seven patients ages 5-15 years of age were analyzed. They presented at the Emergency Service, Polanco Red Cross Orthopedics and Trauma Hospital, between July 1st 2006 and July 1st 2007., Results: The sample size was 27 patients, the highest incidence occurred at 10 years of age, the forearm was the most frequent location, and the treatment of choice was closed surgery. Only one complication occurred, fractures healed before 8 weeks and rehabilitation started before 9 weeks. All of them had permissible angulations and 4 patients had a 2 mm shortening. The use of elastic titanium nails is an effective method to treat long bone fractures, it results in minimal angulations and few complications, and allows patients to promptly resume their activities.

Introduction: Vascular lesion associated with knee dislocation represents a common and potentially devastating complication. A delay in revascularization that exceeds 8 hours can lead to amputation of the extremity. Therefore it is mandatory to do an immediate examination and an effective diagnosis to rule out this complication., Case Report: A 19-year-old male was struck by a motor vehicle and caused traumatic dislocation of the left knee as observed on X-rays. The knee was reduced immediately. At 12 hours, the patient presented edema on the extremity and was then stabilized with external fixators. On the third day the patient developed a compartmental syndrome and artery obstruction, and required fasciotomies and revascularization of the popliteal artery. Twenty four hours later, again the artery was obstructed, conducing to supracondylar amputation., Discussion: The purpose of this article is to show that a knee dislocation, with vascular complications, may lead to extremity amputation as a drastic treatment. It is important to emphasize that vigilance of vascular permeability has to be followed every 2-3 hours, for at least 72 hours after the injury, and assisted with Doppler study. And if needed, at the moment when a pulse abnormality is detected an arteriography study must be realized.
