Compartment Syndrome and Wrist Disarticulation After a Catfish Sting

Catfish have the ability to inflict stings on their victims through spines located on their dorsal and pectoral fins. The stings of catfish can release toxins that have dermonecrotic, edemogenic, and vasospastic factors. In this case, a 56-year-old man suffered a catfish sting to his right thumb, which resulted in acute hand compartment syndrome and resultant hand fasciotomies. His hospital course was complicated by multiple irrigation and debridements, finger amputations, hand fluid cultures positive for Vibrio damsela, and eventual wrist disarticulation. The combination of envenomation, infection, and delayed presentation for treatment ultimately led to a hand amputation.

The Point Digit II: Mechanical Design and Testing of a Ratcheting Prosthetic Finger

ABSTRACT Introduction People with partial hand loss represent the largest population of upper limb amputees by a factor of 10. The available prosthetic componentry for people with digit loss provide various methods of control, kinematic designs, and functional abilities. Here, the Point Digit II is empirically tested and a discussion is provided comparing the Point Digit II with the existing commercially available prosthetic fingers. Materials and Methods Benchtop mechanical tests were performed using prototype Point Digit II prosthetic fingers. The battery of tests included a static load test, a static mounting tear-out test, a dynamic load test, and a dynamic cycle test. These tests were implemented to study the mechanisms within the digit and the ability of the device to withstand heavy-duty use once out in the field. Results The Point Digit II met or exceeded all geometric and mechanical specifications. The device can withstand over 300 lbs of force applied to the distal phalange and was cycled over 250,000 times without an adverse event representing 3 years of use. Multiple prototypes were utilized across all tests to confirm the ability to reproduce the device in a reliable manner. Conclusions The Point Digit II presents novel and exciting features to help those with partial hand amputation return to work and regain ability. The use of additive manufacturing, unique mechanism design, and clinically relevant design features provides both the patient and clinician with a prosthetic digit, which improves upon the existing devices available.

Theft Prevention With Rahat as an Effort to Protect Property in Pasaman, West Sumatera, Indonesia

This article aims to explore about rahat as an effort to protect property in Pasaman, West Sumatera, Indonesia. Stealing was a criminal act which threatened the perpetrator with severe punishment, imprisonment in Indonesia or hand-amputation in Islamic law. The punishment was not only to deter and punish the perpetrator but also to educate society not to make the same mistake. However, when the national and religious laws did not function efficiently, the people in Pasaman, West Sumatera, Indonesia protected their properties with rahat, the magical fence consisting of tayyibah (noble words) which prepared by the leader of Islamic traditional boarding school (pesantren). When a thief broke the fence, he may forget his initial intention to steal, feel being locked, or even sickened in to an unrecoverable illness. Rahat and its effects were announced in public, delivered mouth to mouth, and obeyed by the community. As the result, the people were prevented from taking other people’s possessions; the treasures of society were also well preserved. The type of the study was field research with a qualitative approach. The data was gathered by observation, in-depth interviews, and documentation study. The analysis was done descriptively by data reduction, display, and verification (drawing conclusion).<br /><br />

Neonate born with ischemic limb to a COVID-19 positive mother: management and review of literature

ObjectivesTo describe challenges in diagnosis and treatment of congenital neonatal gangrene lesions associated with history of maternal coronavirus disease 2019 (COVID-19) infection.Case presentationA preterm neonate was born with upper extremity necrotic lesions and a history of active maternal COVID-19 infection. The etiology of his injury was challenging to deduce, despite extensive hypercoagulability work-up and biopsy of the lesion. Management, including partial forearm salvage and hand amputation is described.ConclusionsNeonatal gangrene has various etiologies, including compartment syndrome and intrauterine thromboembolic phenomena. Maternal COVID-19 can cause intrauterine thrombotic events and need to be considered in a differential diagnosis.

A serious complication after forearm replantation caused by a cord tightened on the stump during transportation – a case report

In amputations of an upper extremity, an adequate preservation of the amputated part during its transport to a replantation centre is very important: it needs to be maintained at about 4°C. Providing adequate haemostasis of the extremity stump is also important for the patient’s safety, to avoid bleeding on the journey. The article presents the case of a patient who had sustained a hand amputation at the forearm, in which bleeding from the stump was stopped with a cord that has been tightened on the forearm, 10 cm above the amputation site. Transport for the patient took over 6 h and resulted in a critical ischaemia ofthe forearm stump. Replantation was successfully performed, but an excessive oedema of the ischaemically injured part of the stump developed in the post-operative course, requiring a fasciotomy, resection of the necrotic muscles, following by coverage of the defects with skin grafts. No complications were observed in the replanted part of the forearm, and the prognosis towards recovery of good hand function is moderate, due to the loss of a portion of the forearm muscles.Keywords: hand replantation; postoperative complications; muscle ischaemia; malpractice.
