CASE: A 68-year-old woman who had undergone a right total hip arthroplasty presented with a right posterior hip dislocation, and subsequently developed an ipsilateral sciatic nerve palsy after closed reduction. Magnetic resonance imaging (MRI) with metal suppression demonstrated sciatic nerve entanglement around the prosthetic femoral neck. A sciatic nerve release was performed, resulting in poor early neurologic recovery. CONCLUSION: Sciatic nerve entanglement following closed reduction of a dislocated total hip prosthesis is a rare injury...

CASE: A patient was struck by an agricultural vehicle and sustained ipsilateral hip and knee dislocations. Closed reduction of the hip was accomplished in the emergency department; the patient required general anesthesia in the operating room to reduce the knee dislocation. Nonoperative treatment was used for both injuries, with a good long-term outcome. CONCLUSION: Simultaneous ipsilateral hip and knee dislocations are rare and complex injuries that usually result from high-energy trauma...

The heel comprises the epidermis, minimal subcutaneous tissue, a dense septum, and the calcaneus. Injury to any of these structures can impair the ability to walk. The soft tissue or calcaneal bone can be injured by trauma. Injuries incurred in war are usually high-energy traumas caused by weapons such as rifles, rockets, and land mines. Such injuries can be life threatening and involve the loss of tissue, including skin, soft tissue, bone, and neurovascular tissue. Two main treatment protocols are used for such injuries with large tissue defects: amputation and reconstruction...

Introduction: Humerus non-union is a challenging situation for the surgeon and devastating and morbid situation for the patient. Surgical approach to the humerus is demanding because of the complex neurovascular anatomy and especially when previous surgeries have been attempted. Case Report: We report a case of a young adult male who sustained a compound fracture of humerus shaft treated with intramedullary nailing followed by subsequent bone grafting and eventually landed up in non-union and was treated at our center by locking compression plate application with nail in situ with iliac crest autogenous bone graft followed by shoulder spica application...

Peyronie's disease (PD) is an acquired connective tissue disorder of the tunica albuginea with fibrosis and inflammation that lead to palpable plaques formation, penile curvature, and pain during erection. Patients report negative effects on main domains such as physical appearance and self-image, sexual function, and performance. The aim of this study was to evaluate plication of the albuginea outcomes after a long-term follow-up period. Between 1998 and 2006, a total of 204 patients with PD underwent surgical correction with albuginea plication technique...

Minimally Invasive Spine Surgery (MISS) procedures for the treatment of spinal pathologies have experienced exponential growth due to improved techniques and decreased trauma to the patient. Several MISS procedures that require the use of a trans-pedicular cannula as a guiding tool for pedicle screw placement, delivery of biomaterials to the vertebral body or injection of biologics to the disc space have been described. Although these are clear advantages of MISS, the limited dissection and exposure may reduce the accuracy and stability of operation and make spine surgeons rely heavily on intraoperative fluoroscopy, raising concerns over the level of radiation exposure...

A 19-year-old man presented with bitemporal hemianopsia and was found to have a large sellar and suprasellar tumor, resembling a pituitary macroadenoma. Emergency transsphenoidal approach was attempted because of rapid visual deterioration with headache. However, the approach was complicated and stopped by uncontrolled hemorrhage from the tumor. After conventional cerebral angiography and recognition of an unusual pathology, transcranial approach was achieved to prevent permanent visual loss. The final pathological diagnosis was pituicytoma with epithelioid features...

BACKGROUND: Subdermal implantable contraceptives are highly effective, approved in over 60 countries, and used by millions of women. Due to simple insertion and removal protocols, these procedures are often performed in the outpatient clinic setting, and procedural complications are rare. However, given the location of the implant in the medial antebrachial interval, there is a risk of neurovascular injury, especially with malpositioned or deeply placed implants. METHODS: We present a case of proximal median nerve injury leading to severe neuropathy after attempted removal of a subdermal implantable contraceptive requiring neurolysis and tendon transfers...

BACKGROUND/AIMS: Plunging ranulas are oral mucoceles that often cannot be visualized directly and thus can be challenging to diagnose and differentiate from other neck lesions. Surgery is the preferred treatment option, but the optimal approach requires careful consideration. METHODS: We report the case of a plunging ranula presenting as an isolated neck mass in a 33-year-old patient. This patient was treated with a novel transoral robotic surgery (TORS)-assisted approach aided by sialendoscopy...

REVIEW
P Denormandie, N de l'Escalopier, L Gatin, A Grelier, F Genêt
Neurogenic heterotopic ossification of the hip is secondary to neurologic lesions such as cranial trauma, stroke, medullary injury or cerebral anoxia. We shall not deal here with the other etiologies of heterotopic ossification. There are numerous locations within the hip, depending on etiology, and relations with adjacent neurovascular structures are sometimes close. Preoperative work-up should include contrast-enhanced CT; scintigraphy is non-contributive. Indications for surgery are decided in a multidisciplinary team meeting, with a contract laying out expected functional gain...
