RESUMO
Arthrofibrosis is defined as joint pain and stiffness that does not allow functional range of motion and is due to adhesions or contracture of the joint. Arthrofibrosis is characterized by an abnormal proliferation of fibrous tissue that may be focal or diffuse and intra-articular or extra-articular. Trauma and surgery are the most common etiological factors. In the ankle and foot symptomatic arthrofibrosis is not uncommonly seen in the talocrural joint, posterior subtalar joint, and the metatarsophalangeal joints. Imaging can assist with diagnosis and planning treatment, most commonly using MRI and occasionally ultrasound. Typical imaging findings consist of capsular and pericapsular thickening and scarring, best demonstrated on proton-density MR images but also demonstrable on ultrasound.

Surfer's myelopathy is a rare, nontraumatic spinal cord injury that typically occurs in beginner surfers. The condition was first described in 2004 by Thompson et al and usually presents in thin young men. We present a 19-year-old man who developed lower back pain, profound bilateral lower limb paraparesis, and hyperesthesia during his first learn to surf class. The event was not associated with trauma. Subsequent magnetic resonance imaging demonstrated features consistent with spinal cord ischemia. The motor recovery due to surfer's myelopathy is variable; our case remained a paraplegic with a T10 sensory level.
