Evaluating the Best Diagnostic Method for a Potential Growth Plate Fracture in a 14-Year-Old Ankle
What is the most effective way to determine if a 14-year-old has a growth plate fracture in their ankle: an MRI or a series of timed X-rays? After an initial X-ray, no fracture was visible; however, the physician suspects a growth plate issue due to tenderness in the area that persists ten days following the injury. The patient was provided with a protective boot and referred to a specialist, but unfortunately, the consultation is scheduled for three weeks later. What steps can be taken to confirm if there is indeed a fracture? Would a private MRI provide the necessary insights? Alternatively, how accurate are time-spaced X-rays in making this diagnosis? Patient Information: - Age: 14 - Gender: Male - Height: 5'10" - Weight: 135 lbs - Ethnicity: Caucasian - Duration of symptoms: 2.5 weeks following the injury - Location: Canada - Pre-existing medical conditions: None - Current medications: None

To evaluate a potential growth plate fracture in your 14-year-old’s ankle, both MRI and timed X-rays are valid diagnostic methods, but they serve different purposes. Since an initial X-ray did not identify a fracture, and there are ongoing symptoms like tenderness, it’s important to monitor and take appropriate action.
Explanation
-
Growth Plate Fractures: These are common in adolescents due to their still-developing bones. If a fracture is suspected but not seen on X-rays, it can be due to the fracture being very subtle or located within the growth plate, which may not always show up immediately on standard imaging.
-
MRI vs. X-rays:
- MRI is very effective at visualizing soft tissue and provides a detailed view of the growth plate and surrounding structures. It can help confirm or rule out injuries that are not visible on X-rays.
- Timed X-rays may involve taking additional X-rays over a period to observe changes that develop as healing occurs. However, they may not provide the necessary details as efficiently as an MRI would.
Next Steps
-
Consider MRI: If you can access a private MRI appointment, it would likely provide the most accurate information regarding a growth plate fracture. It’s non-invasive and helps in assessing both bone and soft tissue.
-
Monitor Symptoms: Keep an eye on any changes in symptoms. If the tenderness worsens, or if your child experiences increased pain or swelling, it may indicate the need for more urgent care.
-
Use of Protective Boot: Continue using the protective boot as directed, which can help limit movement and support the injured area during this time.
-
Stay on Schedule: While waiting for the specialist consultation, be vigilant about any developments in symptoms and prepare to discuss these at the appointment, emphasizing ongoing pain or functional limitations.
-
Rest and Elevation: Encourage your child to rest the ankle and elevate it when possible to reduce swelling and discomfort.

Experiencing Medical Adhesive for the First Time
I apologize for the awkwardness of this message, as I’m typing with my non-dominant hand. I'm a young woman, and an incident occurred while I was drinking. To keep it brief, I managed to accidentally slice the tip of my thumb off about two hours ago. Thankfully, it wasn’t an extensive injury, but enough to cause bleeding that lasted for roughly 30 minutes, even with pressure applied and my hand elevated. (For context, the cut extends a few millimeters deep, penetrating beyond just the surface layer of skin.) Following the accident, I visited the hospital where they applied medical glue, wrapped it up, and discharged me. As I was leaving, I began experiencing some pain, which persists. Upon returning home, I noticed some blood on the gauze covering the injury, which appeared roughly an hour after I got back. Is this typical? The hospital did not provide any pain relief, which I’m not overly concerned about since it is only my finger, but my tendency to be a bit of a hypochondriac is making me anxious. This is my first experience with such an injury. What’s the recommended method for cleaning it once I change the dressing? Thanks in advance!
Injury from a Fall
A 44-year-old female, standing at 5 feet 2 inches and weighing 111 pounds, has no pre-existing medical conditions. Recently, I experienced a mishap two days ago while wearing platform crocs that led to a fall on a tiled surface. In my instinctive reaction, I landed on my palm. Although I can still move and utilize my hand as usual, I’ve noticed significant swelling and considerable pain in the soft area just below the thumb joint. Moreover, when I apply pressure to this spot, I experience a sharp, pinching sensation radiating up my arm. On several occasions, my thumb has also felt momentarily numb but returns to its normal state shortly thereafter. Should I simply allow more time for recovery? I’d prefer to avoid wasting anyone's time if all that’s required is a few days of rest. I appreciate your assistance!
Seeking Guidance on Long-Term Shoulder Muscle Loss After Dislocation
I am a 25-year-old male, and five years ago, I experienced a dislocation of my left shoulder. While the joint has healed well and I have regained a good range of motion, the muscle in my shoulder has not recovered. There is a noticeable difference in muscle mass when compared to my right shoulder. Additionally, I have lost sensation in the area where the muscle has atrophied. When I touch that spot, I feel almost nothing at all. I recall being informed that sensation might return within six months to two years, but unfortunately, that hasn’t happened. In the gym, I've also realized that my left shoulder functions improperly during workouts. While performing chest and shoulder exercises, it seems as though my triceps compensate excessively, rather than the shoulder muscle engaging as it should. This leads to a very frustrating and unbalanced training experience. At this juncture, I’m concerned that the issue may stem from lasting nerve damage caused by the dislocation. I’m curious whether it’s still feasible to rebuild the muscle or regain sensation after such a lengthy period, or if this condition is likely permanent. Have others found themselves in similar situations years later, and did they manage to make any progress or uncover the root cause of their issues? I’m not seeking a diagnosis; I simply wish to understand if the muscle damage is irreversible or if there remains a possible pathway to recovery. What steps should I consider taking next? I would greatly appreciate any advice or insights regarding my situation. Thank you!
Urinary Retention and Lower Back Discomfort
A 38-year-old male weighing 237 pounds has been experiencing urinary issues over the past five days, noting significantly reduced urine output with a very feeble flow—occasionally just a dribble. Yesterday, he began feeling discomfort in his flank region, near where he suspects his kidney is located. Today, that discomfort continued but intensified. He sought help at a prompt care facility where a urinalysis was conducted, revealing no abnormalities. The medical advice he received was to increase his fluid intake. While at the facility, he began to experience severe pain in the lower part of his back, right in the center, making bending a challenge. Currently, he is applying ice to the affected area; however, it's uncomfortable for him to lie down or stand. He wonders if the urinary issues and the back pain are connected and is reluctant to visit the emergency room due to financial concerns. Additionally, he recalls a couple of relevant incidents: last Saturday marked the first time he had gone roller skating in many years, during which he noticed some discomfort in the perineum. He has also been dealing with a cyst in his pubic region for a month, which is gradually improving.
Understanding Injuries: Distinguishing Between Tibial Stress Fracture and Anterior Tibial Tendonitis
Recently, I've ramped up my workout regimen significantly since early December, but I keep facing setbacks with injuries. During December, my routine involved daily outdoor walks and a brief incline walking session, complemented by 30 to 45 minutes of exercise. I noticed a bony protrusion appeared at the back of my right heel, and a similar one started to develop on my left heel as well. When I returned home over the holiday break, my mom arranged for me to see a podiatrist, who diagnosed the right heel bump as a pump bump. On the other hand, the left heel had become a source of greater discomfort and noticeable swelling, to the extent that my Achilles tendon was not visible. The diagnosis for that was Achilles tendonitis. The podiatrist recommended a change of footwear, a steroid treatment plan, anti-inflammatory medications, and a course of physical therapy lasting 4 to 6 weeks. Upon returning to college and anticipating starting physical therapy, I noticed improvements in my ankle discomfort with the new shoes. As a result, I delayed my therapy sessions and resumed a more regular workout routine. Since then, I have been free from significant pain, and both heels are feeling better. My regimen over the last two to three weeks involves about an hour of strength training followed by a two-hour treadmill session—beginning with an incline of 10 at a speed of 3.5, progressively lowering the incline and raising the speed every 10 to 12 minutes. During this treadmill time, I generally study, so I remain engaged. On days when I don’t use the treadmill, I aim to walk several miles outdoors, taking advantage of the hilly terrain on my campus. Sundays serve as my primary rest day, but I still try to complete my fitness rings and take longer walks. Just this past Sunday, I undertook a 10-mile walk that lasted around 2.5 hours, and I noticed the following day that I had discomfort in my right shin. Initially, I assumed it was shin splints and continued my usual activities throughout the week. However, by yesterday, I recognized that the pain was persistent and not improving. Upon closer examination, it seemed like it wasn’t typical shin splint pain; instead, I have localized pain the size of a quarter on the front area of my shin that is tender to the touch and during movement. Mornings tend to be slightly better, but the pain worsens at night after a day spent on my feet. Routine activities aggravate it, and when I walk, it feels akin to a hammer striking my shin. Moreover, if I walk normally and push off with my toes at the end of my stride, a sharp pain radiates up my shin. I have also noted moments where my gait has altered slightly, and I’ve started limping without realizing it, though I can correct my stride when I concentrate. The most discomfort was felt last night after I returned home to my apartment. While lying on my stomach with my legs hanging off the bed, I could still sense the pain even without any movement. Although the pain escalates with weight-bearing activities or when walking, I also experience pain if I sit down with my feet flat and then lift my leg. Driving is particularly challenging as switching between pedals causes significant discomfort. In trying to pinpoint the issue online, I found that my symptoms seemed more closely aligned with a stress fracture rather than the shin splints I initially presumed. I read concerning accounts of stress fractures evolving into full breaks and potentially leading to longer recovery times. Not wanting to prolong my downtime unnecessarily, I decided to visit urgent care today for a professional evaluation. They conducted x-rays but found no visible abnormalities. The doctor performed a few movements and suspects I might have anterior tibial tendonitis, as there was some crepitus noted. However, fears of a stress fracture still linger. This pain feels distinct from the previous Achilles tendonitis; whereas that felt like a stretching tension, this current sensation resembles a hammer striking my leg when I walk. In contrast, I experience a pulling feeling only when rotating my ankle without weight. I'm uncertain if this all articulates my situation clearly, but I am planning to attend physical therapy soon and will limit incline walking for the time being. Still, I am left wondering if my concerns about a potential stress fracture are warranted, or if this seems more characteristic of tendonitis?
