The patient was investigated due to suspicion of vascular damage.

Biomechanical comparison of distal femoral fracture fixation: Polyaxial vs. uniaxial locking screws with different blocking screw configurations in retrograde femoral nailing.

Introduction: Clinical studies have indicated reduced reliance on blocking screws with the introduction of polyaxial locking nails, yet the biomechanical superiority of polyaxial locking over blocking screws remains unverified, specifically for distal dia-metaphyseal femur fractures.

Hypothesis: We hypothesized that the combination of multiaxial locking using three screws and parallel locking reinforced by two blocking screws would result in superior outcomes compared to utilizing only parallel locking with two screws and one blocking screw.

Materials And Methods: Third-generation custom-made femur models representing AO/OTA 32 A1.

Effectiveness of distally slotted proximal femoral nails on prevention of femur fractures during and after intertrochanteric femur fracture surgery.

Introduction: Intra- and post-operative femoral shaft fractures related with nailing remain of concern. Although manufacturers have sought to solve the problem by providing distally slotted nails, it is not clear that these implants reduce fractures. We compare two distally slotted proximal femoral nails [trochanteric nail (TRON) and proximal femur intramedullary nail (PROFIN)].

Preliminary Report on the Role of Dry Needling Versus Corticosteroid Injection, an Effective Treatment Method for Plantar Fasciitis: A Randomized Controlled Trial.

Plantar fasciopathy (PF) is a common disorder for which there is no consensus regarding an optimal treatment strategy. We hypothesized that dry needling would be as effective as the use of corticosteroid injections for treating PF while avoiding the potential adverse effects of corticosteroids. After approval was received from the institutional review board, patients diagnosed with PF were prescribed a 3-week nonoperative treatment regimen.

Which Emerges First: Bone Marrow Edema or Nidus in Osteoid Osteoma?

This case report describes a well-documented birth and evolution of an osteoid osteoma at the talus. Although initial radiologic images indicate mild bone marrow edema at first (without nidus), subsequent magnetic resonance imaging and computed tomographic images reveal pathognomonic nidus at the talus. During the evolution of the lesion, typical night pain was coincident with the occurrence of the nidus, as seen on magnetic resonance imaging.
