Compartment Syndrome Following Arthroscopic Removal of a Bullet in the Knee Joint after a Low-Velocity Gunshot Injury

Gunshot injuries are getting more frequently reported while the civilian (nongovernmental) armament increases in the world. A 42-year-old male patient presented to emergency room of Istanbul Medipol University Hospital due to a low-velocity gunshot injury. We detected one entry point on the posterior aspect of the thigh, just superior to the popliteal groove. No exit wound was detected on his physical examination. There was swelling around the knee and range of motion was limited due to pain and swelling. Neurological and vascular examinations were intact. Following the initial assessment, the vascular examination was confirmed by doppler ultrasonography of the related extremity. There were no signs of compartment syndrome in the preoperative physical examination. A bullet was detected in the knee joint on the initial X-rays. Immediately after releasing the tourniquet, swelling of the anterolateral compartment of the leg and pulse deficiency was detected on foot in the dorsalis pedis artery. Although the arthroscopic removal of intra-articular bullets following gunshot injuries seems to have low morbidity rates, it should always be considered that the articular capsule may have been ruptured and the fluids used during the operation may leak into surrounding tissues and result in compartment syndrome.

Surgical treatment of nail bed subungual exostosis

<p><b>INTRODUCTION</b>A subungual exostosis (SE) is a bony overgrowth that is permanently attached to the tip of the distal phalanx. Its pathology differs from osteocartilaginous exostoses in that it mainly involves the overgrowth of normal bone, which may present beneath the toenail or on the sides of the toe. This retrospective study aimed to report the results of surgical treatment when the diagnosis of SE was delayed; the condition was initially considered to be another pathology affecting a different nail or the terminal toe.</p><p><b>METHODS</b>A total of 17 patients (12 female, five male) were included in the study. All surgical resections were performed by the same surgeon using the same surgical technique, with the patient under digital anaesthesia. The patients were evaluated pre- and postoperatively (on Weeks 1 and 6, the first year, and the last follow-up visit) using the American Orthopaedic Foot and Ankle Society questionnaire and the Visual Analogue Scale score.</p><p><b>RESULTS</b>The patients underwent surgery for SE removal between December 2009 and October 2012. Their mean age was 21.3 ± 4.4 (range 14-29) years and the mean follow-up period was 27.1 ± 7.8 (range 18-45) months. Clinical or radiological recurrence was not observed in any of the patients during the follow-up period. Four patients had superficial infections, which were treated using appropriate antibiotic therapies.</p><p><b>CONCLUSION</b>As SE is an uncommon benign lesion, its diagnosis may be delayed. Radiography may be useful in obtaining a differential diagnosis.</p>
