The application of three-dimensional (3D) printing is growing explosively in the medical field, and is especially widespread in the clinical use of fabricating upper limb orthosis and prosthesis. Advantages of 3D-printed orthosis compared to conventional ones include its lower cost, easier modification, and faster fabrication. Hands are the most common body parts involved with burn victims and one of the main complications of hand burns are finger joint contractures. Applying orthotic devices such as finger splints are a well-established essential element of burn care. In spite of the rapid evolution of the clinical use of 3D printing, to our knowledge, its application to hand burn patients has not yet been reported. In this study, the authors present a series of patients with hand burn injuries whose orthotic needs were fulfilled with the application of 3D-printed finger splints.

ObjectiveTo examine the usefulness of the second lumbrical-interosseous (2L-INT) distal motor latency (DML) comparison test in localizing median neuropathy to the wrist in patients with absent median sensory and motor response in routine nerve conduction studies.MethodsElectrodiagnostic results from 1,705 hands of patients with carpal tunnel syndrome (CTS) symptoms were reviewed retrospectively. All subjects were evaluated using routine nerve conduction studies: median sensory conduction recorded from digits 1 to 4, motor conduction from the abductor pollicis brevis muscle, and the 2L-INT DML comparison test.ResultsFour hundred and one hands from a total of 1,705 were classified as having severe CTS. Among the severe CTS group, 56 hands (14.0%) showed absent median sensory and motor response in a routine nerve conduction study, and, of those hands, 42 (75.0%) showed an abnormal 2L-INT response.ConclusionThe 2L-INT DML comparison test proved to be a valuable electrodiagnostic technique in localizing median mononeuropathy at the wrist, even in the most severe CTS patients.

Being located in the hypogastric area, the ilioinguinal nerve, together with iliohypogastric nerve, can be damaged during lower abdominal surgeries. Conventionally, the diagnosis of ilioinguinal neuropathy relies on clinical assessments, and standardized diagnostic methods have not been established as of yet. We hereby report the case of young man who presented ilioinguinal neuralgia with symptoms of burning pain in the right groin and scrotum shortly after receiving inguinal herniorrhaphy. To raise the diagnostic certainty, we used a real-time ultrasonography (US) to guide a monopolar electromyography needle to the ilioinguinal nerve, and then performed a motor conduction study. A subsequent US-guided ilioinguinal nerve block resulted in complete resolution of the patient's neuralgic symptoms.
