Ankle Fracture Epidemiology in the United States: Patient-Related Trends and Mechanisms of Injury.

Current nationwide epidemiological data regarding ankle fractures are scarce. Such information is important towards better quantifying the mortality associated with such injuries, financial impact, as well as the implementation of preventative measures. This study evaluated the epidemiology of ankle fractures that occurred during a 5-year period.

Osteoporotic ankle fractures: an approach to operative management.

The incidence of osteoporosis is increasing as the elderly population grows. Because these patients remain active, fragility fractures of the ankle are becoming more common. The literature indicates a relatively high complication rate for non-operative management of ankle fractures in this patient cohort, leading surgeons to face challenges unique to patients with poor bone and skin quality.

Does a high-flexion design affect early outcome of medial unicondylar knee arthroplasty? Clinical comparison at 2 years.

Recently, implant companies have sought to target a more active segment of the population with high-flex implants. Our aim was to compare a successful medial UKA implant with its newer high-flex version. Sixty-one patients (nonflex, 33; high-flex [HF], 28) were prospectively followed after medial UKA with a minimum of 2-year follow-up.

Paratricipital-triceps splitting "two-window" approach for distal humerus fractures.

Commonly, distal transcondylar and intra-articular distal humerus fractures are treated through a transolecranon approach. Other options for exposure, open reduction, and internal fixation exist to prevent the reported complications of olecranon osteotomy. The technique of triceps sparing access, as it has been reported before by others, allow adequate exposure in most of distal humerus fractures except for multifragmentary, mainly intra-articular types.

Innervation of the elbow joint and surgical perspectives of denervation: a cadaveric anatomic study.

Purpose: Peripheral articular denervation has been proposed as an alternative treatment for degenerative arthritis. It shows particular promise in the elbow because the joint is non-weight bearing and easily exposed. Accurate knowledge of peripheral neuroanatomy is required for future denervation surgeries, yet very few studies focus on the articular branches of the ulnar, median, and radial nerves that provide elbow capsule innervation.

Diastolic blood pressure in patients with tibia fractures under anaesthesia: implications for the diagnosis of compartment syndrome.

Objective: In the treatment of tibia fractures, is the intraoperative diastolic blood pressure (DBP) less than pre- and postoperative DBP, and how does this relate to the diagnosis of compartment syndrome using DeltaP (diastolic blood pressure [DBP] - intracompartmental pressure)?

Design, Setting, And Patients: This was a prospective cohort study in a level 1 trauma center, with a consecutive series of 242 patients with a tibia fracture.

Intervention: Intramedullary nail fixation of tibia fractures under general anesthesia.

Main Outcome Measures: Patient demographics, type and location of fracture, injury severity score, and blood pressures preoperatively, intraoperatively, and postoperatively.

Epidermal growth factor differentially affects integrin-mediated adhesion and proliferation of ACL and MCL fibroblasts.

The anterior cruciate ligament (ACL) and the medial collateral ligament (MCL) are two commonly injured structures in the human knee. While the MCL heals post-traumatically, the ACL does not. Since growth factors play a major role in the proliferation phase of wound healing, we compared the differential effects of epidermal growth factor (EGF) on adhesion and proliferation of ACL and MCL fibroblasts.
