RESUMO
BACKGROUND: The aim of this study was to compare the effects of four different immobilization methods [single sugar tong splint (SSTS), double sugar tong splint (DSTS), short arm cast (SAC), and long arm cast (LAC)] commonly used for restricting forearm rotation in the upper extremity. METHODS: Forty healthy volunteers were included in the study. Dominant extremities were used for measurements. Basal pronation and supination of the forearm were measured with a custom-made goniometer, and the total rotation arc was calculated without any immobilization. Next, the measurements were repeated with the SAC, LAC, SSTS and DSTS. Each measurement was compared to the baseline value, and the percentage of rotation restriction was calculated. RESULTS: The most superior restriction rates were observed for the LAC (p = 0.00). No statistically significant difference was detected between the SSTS and DSTS in terms of the restriction of supination, pronation or the rotation arc (p values, 1.00, 0.18, and 0.50, respectively). Statistically significant differences were not detected between the SAC and the SSTS in any of the three parameters (p values, 0.25; 1.00; 1.00, respectively). When the SAC and DSTS were compared, while there was no significant difference between the two methods in pronation (p = 0.50), a statistically significant difference was detected in supination (p = 0.01) and in the total rotation arc (p = 0.03). CONCLUSION: The LAC provides superior results in restricting forearm rotation. The SAC and SSTS had similar effects on forearm rotation. The DSTS, which contains, in addition to the SSTS, a sugar tong portion above the elbow, does not provide additional rotational stability.

INTRODUCTION AND CLINICAL IMPORTANCE: Human scabies is a contagious skin condition caused by the Sarcoptes scabiei mite, leading to skin damage and subsequent mechanical irritation from scratching. This impaired skin integrity predisposes individuals to skin infections. While the association between scabies and skin infections caused by Staphylococcus aureus and Streptococcus pyogenes is well-documented, there is limited literature on the risk of surgical site infections in such cases. CASE PRESENTATION: This case report aims to explore this risk by presenting a case of surgical site infection caused by Streptococcus pyogenes following surgery for a complex elbow injury in a patient with scabies infestation. DISCUSSION: Scabies infestation leads to direct spread of bacteria and contributes to bacterial infection. Furthermore, complement inhibition and dysbiosis induced by the scabies may facilitate the occurrence of these bacterial infections. CONCLUSION: Skin infections are frequently encountered in scabies infestations. Preferred incision should be evaluated meticulously before surgery. Further studies are needed to reach a definitive conclusion on this subject.
