RESUMEN
Background: Surgery for hand trauma accounts for a significant proportion of the plastic surgery training curriculum. The aim of this article is to create a standardised simulation training module for hand fracture fixation on open reduction and internal fixation (ORIF) techniques for residents in order to create a standardised hand-training framework that universally hones their skill and prepares them for their first encounter in a clinical setting. Methods: A step-ladder approach training using three-dimensional (3D)-printed ex vivo hand biomimetics was employed on a cohort of 15 plastic surgery residents (n = 15). Assessment of skills using a score system (global rating scale) was performed in the beginning and the end of the module by hand experts in our unit. Results: The overall average score of the cohort pre- and post-assessment were 22.08/50 (44.16%) and 41.54/50 (83.08%) respectively. Significant (p < 0.01) difference of improvement of skills was noted on all trainees. All trainees confirmed that the simulated models provided in this module were akin to the patient scenario and noted that it helped them improve their skills with regards to ORIF techniques including improvement of their understanding of the 3D bone topography. Conclusion: We demonstrate a standardised simulation training framework that employs 3D-printed ex vivo hand biomimetics proven to improve the skills of residents and which paves the way to more universal, standardised and validated training across hand surgery. This is, to our knowledge, the first standardised method of simulated training on such hand-surgical cases.Level of Evidence: Not ratable.
RESUMEN
BACKGROUND: Surgery for hand trauma accounts for a significant proportion of the plastic surgery trainee activity. The aim of this article is to create a standardised simulation training module for flexor tendon repair techniques for residents prior to their first encounter in the clinical setting. METHODS: A step-ladder approach flexor tendon repair training with four levels of difficulty was conducted using a three-dimensional (3D) printed anatomical simulation model and a silicone tendon rod on a cohort of 28 plastic surgery Senior House Officers (SHOs) of various stages in their training (n=28). Assessment of knowledge (online questionnaire) and practical skills using validated score systems (global rating scale and task specific score) was performed at the beginning and end of the module by hand experts of our unit. RESULTS: The overall average knowledge-based scores of the cohort pre- and post-assessment were 1.48/5 (29.6%) and 3.56/5 (71.5%), respectively. The overall average skills-based scores of the cohort pre- and post-assessments were 3.05/5 (61%) and 4.12/5 (82.5%), respectively. Significant (p<0.01) difference of improvement of knowledge and skills was noted on all trainees. All trainees confirmed that the training module improved their confidence with flexor tendon repair. CONCLUSION: We demonstrate a standardised simulation training framework that employs a 3D printed flexor tendon simulation model proven to improve the skills of residents especially during their early learning curve and which paves the way to a more universal, standardised and validated training across hand surgery.

Surgery for hand trauma accounts for a significant proportion of the plastic surgery training curriculum. The aim of this study was to create a standardized simulation training module for hand fracture fixation with Kirschner wire (K-wire) techniques for residents to create a standardized hand training framework that universally hones their skill and prepares them for their first encounter in a clinical setting. METHODS: A step-ladder approach training with 6 levels of difficulty on 3-dimensional (3D) printed ex vivo hand biomimetics was employed on a cohort of 20 plastic surgery residents (n = 20). Assessment of skills using a score system (global rating scale) was performed in the beginning and at the end of the module by hand experts of our unit. RESULTS: The overall average scores of the cohort before and after assessment were 23.75/40 (59.4%) and 34.7/40 (86.8%), respectively. Significant (P < 0.01) difference of improvement of skills was noted on all trainees. All trainees confirmed that the simulated models provided in this module were akin to the patient scenario and noted that it helped them improve their skills with regard to K-wire fixation techniques, including improvement of their understanding of the 3D bone topography. CONCLUSIONS: We demonstrate a standardized simulation training framework that employs 3D printed ex vivo hand biomimetics proved to improve the skills of residents and that paves the way to more universal, standardized and validated training across hand surgery. This is, to our knowledge, the first standardized method of simulated training on such hand surgical cases.
RESUMEN
Many burns surgeons avoid excision and direct closure of acute burns owing to concerns over wound dehiscence, scarring and infection. There is no evidence in the literature to support this practice. We present outcomes of a prospective series of 100 patients who underwent excision and direct closure of 138 burns over a 2-year period, along with results from a survey sent to 33 senior burns surgeons to gauge attitudes towards direct closure in burns surgery. 47% of survey respondents never perform direct closure. Dehiscence was cited as the most common concern, followed by hypertrophic scarring (HTS). In our cohort, the superficial dehiscence rate was 12% and the HTS rate was 16%, with no scarring contractures. Patients with healing time greater than 14 days were more likely to develop HTS (p=0.008), as were those with wound dehiscence (p=0.014). Patients undergoing part-grafting in addition to direct closure took significantly longer to heal than those undergoing direct closure alone (p=0.0002), with the donor site or graft delaying healing in the majority. Excision and direct closure of acute burn wounds avoids donor site morbidity and has an acceptable complication rate. It is a safe and effective treatment for full thickness burns in selected cases.

We present a case of infection of an alloplastic chin implant occurring 45 years after placement. The patient was referred to the clinic with an ulcerated submental lesion, which was thought to be a squamoproliferative lesion until surgery. The authors discuss the management of the case with reference to the literature on genioplasty and late infection of alloplastic implants.

Torsion or rupture of an ovarian cyst may present as an acute abdomen. A case is presented where the diagnosis was made at laparoscopy and laparoscopic resection was done. Controlled aspiration of the cyst contents allowed the cyst to be easily removed from the abdomen.
