Background: Our objective was to establish a sustainable educational partnership and clinical exchange between the trauma services at Vancouver General Hospital (VGH) and the Mexican Red Cross hospital in Mexico City (Hospital Central de la Cruz Roja [HCCR] Polanco). Methods: In 2017, a general surgery resident in postgraduate year 4 travelled from VGH to HCCR Polanco for the initial exchange, followed by a trauma fellow. The surgical case volumes in a month at VGH and a month at HCCR Polanco were compared. At the end of the exchange, a 36-item Likert style questionnaire was administered to the Mexican surgeons and residents who interacted with the Canadian resident and fellow during the exchange. Results: The most commonly performed procedures on the VGH acute care surgery service were laparoscopic cholecystectomy (35%) and laparoscopic appendectomy (17%). The most commonly performed procedures on the VGH trauma service were chest tube insertions (24%) and tracheostomies (24%). The most commonly performed procedures at HCCR Polanco were surgery for penetrating abdominal trauma (19%) and extremity trauma (13%). The survey results indicated that the costs of travel and accommodation were obstacles to future exchanges. All survey respondents wanted to continue collaborating with Canadians on clinical and research endeavours, felt that hosting Canadian residents was a valuable experience and felt that visiting VGH would also be valuable. Conclusion: Canadian surgical trainees gained valuable exposure to operative trauma during the exchange. The mix of operations performed at VGH and HCCR Polanco was vastly different; therefore, the exchange broadened the trainees' surgical experience. There was a unanimously positive response to the exchange among the Mexican survey respondents. This exchange is part of a long-term collaboration between our surgical centres.

Introduction: Mallet injuries are common and usually treated conservatively. Various systematic reviews have found a lack of evidence regarding the best management, and it is still unclear. Objective: To evaluate the treatment efficacy of Stack Splinting compared to a Kirschner wire immobilization of acute closed mallet finger Doyle I. Methods: From March 2019 to February 2020, 41 patients with acute close mallet finger Doyle I were treated; 19 patients were treated with Kirschner wire and 22 with Stack splinting for a mean of 6 weeks. The average patient age at the time of the injury was 43 years. Results: Twenty-eight males and 13 females were in this study. Among them, 17 patients were injured in the little finger, 15 in the middle finger, and 9 in the ring finger. Twenty-seven of injuries suffered an aggression, 11 from falling, and 3 from sports injuries. All the fingers had typical mallet malformation. Seventeen patients treated with Kirschner wire completed the treatment with full recovery, only 7 patients treated with Stack splint completed the treatment and 15 treated with Stack splint had relapse on mallet injury. Conclusion: Kirschner wire treatment is a simple procedure, and proves in this study that has better results in patients with acute closed mallet finger Doyle I compared to Stack splint.

Multiple enchondromatosis is a rare disease in which cartilage tumors appear at the level of the skeleton. The incidence is unknown due to the very few cases reported in world literature. We presented the case of a patient at the plastic surgery department at General hospital Dr. Ruben Leñero, otherwise healthy, referring first clinical manifestations at childhood with an increase in volume and deformity at the second and third fingers of the left hand.
