X-Ray Analysis - Pelvis AP View
Patient details on film: Female, 2Y (2 years old), Pelvis AP, dated 05/07/2026 - R Medical Center, Sector-25, Panchkula
Fracture Finding
Right Inferior Pubic Ramus Fracture
- A minimally displaced fracture line is visible at the right inferior pubic ramus (appears on the left side of the image, which is the patient's right side)
- The fracture is located near the junction of the inferior pubic ramus and the ischial ramus
- There is a slight cortical step-off/displacement at the fracture site
- It is not completely displaced - the bony fragments remain in close proximity
Rest of the Pelvis - No Other Fractures
| Structure | Finding |
|---|---|
| Left pubic rami (superior & inferior) | Intact, no fracture |
| Both femoral heads | Well-seated in acetabula |
| Femoral necks (bilateral) | No fracture visible |
| Sacroiliac joints | Symmetric, intact |
| Pubic symphysis | Aligned, no widening/diastasis |
| Sacrum | No obvious fracture (subtle non-displaced sacral fractures can be missed on AP view) |
Clinical Correlation Needed
This is a 2-year-old female child - in pediatric patients, pubic ramus fractures from trauma should raise clinical concern and warrant:
- Full trauma history
- Assessment for associated injuries (urinary tract, bladder, soft tissue)
- In young children, non-accidental injury must be considered and ruled out

Here is the complete clinical overview based on authoritative orthopedic textbooks and current literature:
Right Inferior Pubic Ramus Fracture - Diagnosis & Treatment
Fracture Classification
This fracture is classified as a Tile Type A (Stable) pelvic fracture - specifically an isolated single pubic ramus fracture. In pediatric terms (per the 2024 JAAOS pediatric pelvic ring review), it falls under anterior ring lesion involving the ischiopubic ramus.
Below is the reference diagram of pelvic bone fracture types (label 5 = inferior pubic ramus fracture, which matches this patient):
Fig: Fractures of Individual Pelvic Bones. (4) Superior pubic ramus; (5) Inferior pubic ramus - as seen in this patient. From ROSEN's Emergency Medicine, 10th Ed.
Mechanism of Injury
- In a 2-year-old, this most commonly results from:
- Direct trauma - fall, crush injury, or road traffic accident
- Non-accidental injury (NAI/child abuse) - must be actively ruled out at this age
- The normal pelvis has elastic ligaments and soft bone in young children, making isolated ramus fractures possible without ring disruption
Diagnosis
Clinical Features
| Feature | Detail |
|---|---|
| Pain | Groin, hip, or inner thigh pain; worsens with movement |
| Tenderness | Localized to pubic ramus on palpation |
| Gait | Limping or refusal to walk (antalgic gait) |
| Swelling/bruising | May be present over perineum or inner thigh |
Imaging Workup
- AP Pelvis X-ray (already done) - shows the fracture
- CT Pelvis - if any concern for posterior ring injury, displacement, or associated injuries
- MRI - can detect occult sacral fractures not visible on plain films (up to 95% of patients with isolated ramus fractures on X-ray have an occult sacral fracture on MRI, though this rarely changes management)
- Bone scan - rarely needed in acute setting
Important: Posterior Ring Check
The identification of a single anterior break in the pelvic ring should always prompt a search for a second disruption. Look for:
- Sacroiliac joint injury
- Sacral fractures
- Widening of the pubic symphysis
- Avulsion of L5 transverse process
(ROSEN's Emergency Medicine, p.668)
⚠️ Pediatric-Specific Concern
In a 2-year-old child, a pubic ramus fracture from a fall is unusual. Always assess for:
- Non-accidental injury (NAI) - skeletal survey if suspected
- Ischiopubic synchondrosis (normal growth center in young children at the ischiopubic junction) - can be mistaken for a fracture or can be the actual fracture site
Treatment
Conservative Management (First Line for Stable Fractures)
This fracture is mechanically stable and the standard treatment is non-operative:
| Step | Detail |
|---|---|
| Analgesia | Paracetamol +/- NSAIDs (age-appropriate dosing); opioids if severe |
| Rest | Bed rest initially; limit weight bearing on affected side |
| Mobility | Crutches or walking frame when pain allows; weight bearing as tolerated |
| Physiotherapy | Gentle mobilization and muscle strengthening after pain subsides |
| Follow-up | Orthopedic review in 1-2 weeks; repeat X-ray at 4-6 weeks |
Expected healing: 6-8 weeks in children (faster bone healing than adults).
When to Consider Admission
- Intractable pain not controlled with oral analgesia
- Inability to mobilize safely
- Suspected associated injuries (bladder, urethral, vascular)
- Concern for non-accidental injury
Surgical Management (Not typically required)
Surgery is reserved for:
- Unstable pelvic ring injuries (not this case - this is isolated and minimally displaced)
- Significant displacement with posterior ring disruption
- If part of a complex polytrauma
- Per the 2024 JAAOS review (PMID: 38967987), external fixation may be used for unstable anterior ring injuries in children when needed
(Tintinalli's Emergency Medicine; ROSEN's Emergency Medicine, 10th Ed.)
Associated Injury Screening (Important at this age)
| System | Concern | Action |
|---|---|---|
| Urinary tract | Bladder or urethral injury with anterior pelvic fracture | Check urinalysis; if blood at urethral meatus, urology consult before catheterization |
| Vascular | Rare in isolated ramus fractures | Monitor for hemodynamic instability |
| Soft tissue | Perineal/labial hematoma in girls | Clinical examination |
| Spine | Associated spinal injuries if high-energy trauma | Assess clinically |
Prognosis
Isolated inferior pubic ramus fractures in children carry an excellent prognosis. Children's bones heal rapidly, and most achieve full recovery with no long-term sequelae. Return to normal activity is expected within 6-8 weeks.

Here is the complete clinical picture based on authoritative orthopedic textbooks and recent literature:
Diagnosis & Treatment: Left Pelvic Pain after Long Jump
Most Likely Diagnosis
Avulsion Fracture of the Left Anterior Inferior Iliac Spine (AIIS)
In a long jumper, the most likely injury is an AIIS avulsion fracture caused by the violent contraction of the rectus femoris muscle during the take-off or landing phase of the jump.
"Forceful contraction of the rectus femoris (as in kicking a ball or jumping) can result in anterior inferior iliac spine avulsion."
- ROSEN's Emergency Medicine, 10th Ed., p. 670
Fig: Pelvic apophyseal avulsion sites - (1) Iliac crest, (2) ASIS, (3) AIIS, (4) Lesser trochanter, (5) Ischium/ischial apophysis - Campbell's Operative Orthopaedics, 15th Ed. 2026
Why This Happens in Long Jump
| Mechanism | Detail |
|---|---|
| Force | Sudden, forceful muscular contraction OR excessive muscle stretch during jump take-off |
| Muscle involved | Rectus femoris (origin: AIIS) - powerful hip flexor used explosively in jumping |
| At-risk population | Adolescent athletes - the cartilaginous apophysis is weaker than the muscle-tendon unit, so bone fails before the muscle tears |
| Why athletes | In adults, the same force causes muscle/tendon injury; in adolescents with open growth plates, the apophysis avulses instead |
Other Possible Avulsion Sites (Differential by Anatomy)
| Site Avulsed | Muscle Responsible | Sport Association |
|---|---|---|
| AIIS (most likely here) | Rectus femoris | Long jump, sprinting, kicking |
| ASIS | Sartorius | Sprinting, hurdling |
| Ischial tuberosity | Hamstrings | Sprinting, gymnastics |
| Iliac crest | Tensor fasciae latae / abdominal muscles | Contact sports |
| Lesser trochanter | Iliopsoas | Gymnastics, dance |
(Campbell's Operative Orthopaedics, 15th Ed. 2026; Tintinalli's Emergency Medicine)
Clinical Features
Symptoms:
- Sudden sharp pain in left anterior pelvic/groin/hip region at the moment of jump take-off
- Immediate inability or difficulty bearing weight
- Pain worsens with hip flexion against resistance (rectus femoris activation)
Signs on Examination:
- Localized tenderness over left AIIS
- Swelling and possibly bruising over anterior pelvis
- Hip flexion strength reduced and painful
- Pain relieved when hip is slightly flexed (takes tension off rectus femoris)
Investigations
| Investigation | Purpose |
|---|---|
| AP Pelvis X-ray (first line) | Shows bony fragment avulsed from AIIS; may be subtle |
| CT pelvis | Better delineation of fragment size and displacement; rarely required |
| MRI | Detects soft tissue injury, cartilage injury, and subtle apophyseal injuries not seen on X-ray |
| Ultrasound | Bedside assessment; can show fluid and displaced fragment |
Note: On the X-ray already taken (AP Pelvis), look carefully at the left AIIS region for a small bony fragment displaced inferiorly.
Treatment
Conservative Management (First Line - Majority of Cases)
Per ROSEN's Emergency Medicine and Campbell's Operative Orthopaedics (15th Ed. 2026):
| Phase | Management | Duration |
|---|---|---|
| Acute (0-2 weeks) | Rest; non-weight bearing with crutches; ice; analgesics (NSAIDs/paracetamol); hip positioned in slight flexion to reduce tension on rectus femoris | 1-2 weeks |
| Subacute (2-6 weeks) | Gentle range-of-motion exercises; progressive weight bearing as pain allows; physiotherapy begins | Weeks 2-6 |
| Rehabilitation (6-12 weeks) | Strengthening exercises; gradual return to running and sport-specific training | Weeks 6-12 |
| Return to sport | Full return after pain-free, full strength restored | Usually 8-12 weeks |
Surgical Management (Selective Cases)
Per 2022 scoping review, Di Maria et al., PMID 36210934 of 453 patients:
Surgery is preferred when:
- Fragment displacement ≥ 2 cm - the pull of rectus femoris prevents healing in position
- Non-union with chronic pain after conservative treatment
- Competitive athletes requiring faster, more complete return to sport (surgical group had higher return-to-sport rate, p<0.05)
- Excessive callus / myositis ossificans causing mechanical impingement
Surgical options:
- Open reduction and internal fixation (ORIF) with screw or suture anchor
- Excision of non-united fragment if chronic
"Operative treatment does not guarantee the return of the athlete to the same standard as before the injury." - Campbell's Operative Orthopaedics, 15th Ed. 2026
Prognosis
- Good to excellent with conservative treatment for most patients
- Full recovery and return to sport expected in 8-12 weeks
- Rare complications: myositis ossificans, non-union, ischiofemoral impingement
- Competitive athletes with large displacement (≥2 cm) may benefit from surgical fixation for optimal sport return
Key Clinical Points
- Always check the X-ray for fragment displacement - this determines conservative vs. surgical path
- In adolescent athletes, avulsion fractures are more common than muscle tears due to weaker apophyseal cartilage
- AIIS avulsion is the #1 site in jumping athletes (31% of all pelvic avulsions per meta-analysis)
- Orthopedic referral within 1 week for follow-up
