This patient was seen at their hometown medical clinic on Nov26 and prescribed the antibiotic augmentin orally. On Nov27 the patient’s condition remained unchanged and he was referred to the local hospital Emergency Department where he received four doses of IV clindamycin over the next two days followed by 13 days of oral clindamycin, 3X’s/day. On Nov30 the olecranon bursa was lanced and packed open for drainage until Dec4. Diagnosis was septic olecranon bursitis due to staphylococcus infection. The strain of staph was not MRSA and when cultured was resistant only to penicillin and ampicillin. After 21 days patient had made a full recovery.
It may be difficult to decide if local swelling, without an obvious wound, is due to a muscle strain, bug bite, or infection. The possibility of a deep infection, which can develop into a serious tissue-destroying lesion, is a concern. In some cases, history may help rule out the muscle strain.
It’s important to recognize the signs of infection that are inconsistent with "tweaking" the elbow. The redness and fever are red flags that something else may be going on. A typical musculoskeletal injury might be swollen and painful but shouldn't have signs of an infection. If infection is a concern, antibiotics should be started to try to avoid progression and can be discontinued later.
The four cardinal signs of a soft tissue infection are: redness, swelling, warmth, and local pain. There also may be faint red streaks radiating from the site, fever, chills, swollen lymph nodes, pus draining from the wound, or abscess formation. The progression of increased pain, warmth, increased soft tissue swelling, and expansion of redness over 18-24 hrs suggests infection. Drawing a circle around the swollen area with a pen will help you determine if the infection is spreading or resolving.
