CASE: We will present the case of a 6-year-old girl who presented with a 3-cm limb length discrepancy after intraosseous line placement at age 14 months without other known history of trauma or infection to account for the growth arrest. Imaging revealed a left proximal tibial physeal bar amenable to surgical resection with autologous lipotransfer. At 10 months postoperatively, physical examination and imaging demonstrated a stable 3-cm leg length discrepancy with an interval increase in the length of the left tibia in proportion to the growth of the right side with an increase in valgus alignment that will continue to be monitored and addressed as indicated...

CASE: We present a case of an 8-year-old boy with classical bladder exstrophy and a neglected right hip dislocation, exemplifying the risk of missed developmental dysplasia of the hip (DDH) in patients with exstrophy requiring careful orthopaedic oversight. CONCLUSIONS: When treating patients with bladder exstrophy, physicians and surgeons should be vigilant not to miss associated DDH. If this condition requires surgical treatment, preoperative planning with computed tomography scans is vital to uncovering the complexities arising from abnormal pelvic and acetabular anatomy and ensuring successful treatment outcomes...

CASE: We present the case of a 25-year-old man with body mass index of 77 who underwent open reduction internal fixation (ORIF) of a displaced fracture dislocation of the acetabulum after a high-speed motor vehicle accident. Remarkably, he achieved full weight-bearing with minimal hip pain and has returned to independent mobility and meaningful work. CONCLUSION: ORIF of an acetabular fracture in a patient with class III obesity presents many challenges. Positioning, surgical approach, fracture manipulation, and postoperative morbidity and mortality can be managed through interdisciplinary collaboration and preoperative communication...

CASE: A 16-year-old boy presented with a recurrent distal femur aneurysmal bone cyst accompanied by a combined sagittal knee deformity (20° of femoral antecurvatum and 26.8° of tibial recurvatum) and limb shortening. After preoperative planning, the treatment involved new intralesional curettage, phenolization, and bone allograft filling. Additional procedures included distal extension femoral osteotomy with plate fixation, and proximal tibial osteotomy with, gradually corrected through a hexapod frame...

CASE: A 4-year-old girl patient presented with complete amputation of the second toe close to the distal interphalangeal joint. Replantation was performed using a novel midlateral approach. The procedure used the dorsal subcutaneous vein on the foot as a graft for the artery. Four months postoperatively, the toe healed without any complication. The patient reported pain-free physical exercise without limitations in daily activity. CONCLUSION: This report demonstrates that this approach has the potential to provide a safe and viable alternative for treating toe amputations and offers advantages such as simplified artery identification, straightforward anastomosis, and improved vein graft harvesting...

CASE: Neglected elbow dislocation and radial neck malunion frequently result in chronic pain, instability, and early arthrosis. These complications are best prevented by early treatment with open reduction, corrective osteotomy, and ligament reconstruction, followed by early supervised physiotherapy. We present a peculiar case with neglected complex elbow dislocation and radial head malunion. In this case, we performed an open reduction of the elbow joint and radial neck corrective osteotomy, medial collateral ligament, annular ligament reconstruction, and lateral collateral ligament repair...

CASE: The patient, a 21-year-old female Division I track and field athlete, presents with bilateral calf pain, tightness, numbness, and swelling during activity. Initially diagnosed with chronic exertional compartment syndrome (CECS), she underwent bilateral four-compartment fasciotomies. After 4 months, she experienced persistence of some of her prefasciotomy symptoms and was referred to vascular surgery. A fibrous band was compressing the popliteal artery, making the diagnosis of popliteal artery entrapment syndrome (PAES)...

CASE: A 23-month-old otherwise healthy female child from a low opportunity index neighborhood presented with 1 month of lower extremity pain and refusal to bear weight. Radiographic evaluation of bilateral knees revealed lucent metaphyseal bands and a nondisplaced distal femoral metaphyseal corner fracture. A workup identified vitamin C deficiency (scurvy), and the child's symptoms and radiographic abnormalities resolved with vitamin C supplementation. CONCLUSIONS: Scurvy should be considered in children with unexplained musculoskeletal symptoms who may lack access to nutrient-dense foods...

CASE: A 31-year-old patient presented with an encapsulated sciatic nerve secondary to extensive hip heterotopic ossification (HO), which prevented visualization of a safe osteotomy site to avoid nerve damage. The 3D-printed model demonstrated an easily identifiable osseous reference point along the inferior aspect of the heterotopic mass, allowing for a vertical osteotomy to be safely performed. CONCLUSION: HO is associated with loss of normal anatomic topography...

CASE: A 15-month-old boy who was being followed for developmental dysplasia of the hip because of breech presentation was discovered to have a solitary infantile myofibroma in the left femoral neck. The patient was avoiding weight-bearing on the affected extremity; thus, stabilization of the femoral neck was performed using a proximal femur locking plate. Postoperatively, he achieved all gross motor developmental milestones. CONCLUSION: This report is the first to describe a solitary infantile myofibroma in the femoral neck and demonstrates the utility of operative stabilization of these lesions...

CASE: A young girl without pertinent medical history presented with a leg length discrepancy and an awkward gait disturbance. After a rapid growth spurt during the following year, other symptoms became obvious, she developed an inability to sit crossed legged, and her range of motion of the left hip decreased. Hip magnetic resonance imaging demonstrated a left unilateral fibrous band between the iliac wing and the greater trochanter. CONCLUSION: A fibrous band is a rare cause of leg length discrepancy and gait disturbance...

CASE: A 60-year-old man sustained a massive irreparable rotator cuff tear and axillary nerve palsy with deltoid dysfunction after an anterior shoulder dislocation. He underwent staged reverse end-to-side radial-to-axillary nerve transfer with return of deltoid function allowing for subsequent reverse shoulder arthroplasty. At 1 year postoperatively, he returned to full activity. CONCLUSION: Irreparable rotator cuff tears complicated by axillary nerve palsy can be effectively treated with a staged approach of nerve transfer followed by reverse shoulder arthroplasty...

CASE: A 30-year-old man had cervical radiculomyelopathy and neck pain caused by a massive intraosseous neurofibroma (IONF) originating from the C6 vertebrae. We performed posterior tumor resection with spinal instrumentation and fusion from C3 to T2 and a follow-up resection procedure of the remaining C6 anterior tumor, sacrificing the affected vertebral artery (VA), which accordingly required bypass surgery at 2 months recovery. Reconstruction using a titanium mesh cage was successfully performed...

CASE: A 69-year-old man underwent a C3-4 anterior cervical discectomy and fusion and developed postoperative hypoglossal and glossopharyngeal palsies that resolved with symptomatic treatment. CONCLUSION: Cranial nerve palsy is a rare and possibly under-reported injury after higher-level cervical spine surgery. Conscientious positioning and awareness of these nerves during surgical exposure are crucial to minimizing cranial nerve palsies. Proper workup to identify these palsies and differentiate them from other complications is necessary to guide proper treatment...

CASE: A 15-year-old female rock climber presented with a traumatic coracoid process fracture of her dominant upper extremity that failed extensive nonoperative treatment. She was treated successfully by arthroscopic reduction and suture anchor fixation. CONCLUSION: A novel surgical technique for coracoid fracture that combines arthroscopic reduction with suture anchor fixation can result in expeditious and durable clinical improvement in a young, high-demand athlete...

CASE: A 77-year-old woman who sustained a distal radius and ulna fracture underwent open reduction internal fixation through a standard flexor carpi radialis (FCR) approach. On dissection, a proximal division of the median nerve was identified, with an aberrant motor branch crossing radial to ulnar deep to FCR and superficial to flexor pollicis longus. CONCLUSION: Although many anatomic variants of the median nerve have been described, the current case demonstrates a particularly important median motor branch variant, imposing a substantial risk of iatrogenic injury during a standard FCR approach...

CASE: We report a case in the United States of a 12-year-old girl with multidrug-resistant tuberculous (MDR-TB) osteomyelitis of the hand managed with surgical debridement and second-line anti-TB therapy. The disease course was complicated by dissemination and multifocal progression. CONCLUSION: Despite early intervention, multidrug resistance makes TB treatment challenging and facilitated progression to disseminated disease in this case. We review the difficulties in diagnosis and treatment of pediatric MDR-TB...

CASE: A 19-year-old female athlete experienced calf pain during sport. A complete Achilles tendon rupture was diagnosed 4 weeks after injury. Ultrasound revealed discontinuity of the Achilles tendon with 2.0 cm of diastasis, persisting in plantarflexion. Plantarflexion immobilization was initiated, and progressive dorsiflexion was used until 10 weeks from injury. At 1 year from injury, ankle magnetic resonance imaging revealed a contiguous tendon, the patient was pain-free, and had returned to high-level athletics with equivalent sport performance relative to her preoperative status...

CASE: We present the case of a 46-year-old patient with asymmetric deformity in the posterior tibial slope after previous high tibial osteotomy surgeries with the presence of a medial osteotomy plate. A customized cutting guide was designed to fit on the plate to perform a single surgery and avoid possible soft-tissue complications after multiple surgeries. CONCLUSIONS: The presence of a previous internal fixation device may affect the manufacture of 3-dimensional cutting guides...
