Biologic therapies for foot and ankle injuries.

Introduction: The use of orthobiologics as supplemental treatment for foot and ankle pathologies have increased in the past decades. They have been used to improve the healing of bone and soft tissue injuries. There have been several studies that examined the use of biologics for knee and hip pathologies but the foot and ankle construct has unique features that must be considered.Areas covered: The biologics for foot and ankle injuries that are covered in this review are platelet-rich plasma (PRP), stem cells, growth factors, hyaluronic acid, bone grafts, bone substitutes, and scaffolds. These modalities are used in the treatment of pathologies related to tendon and soft tissue as well as cartilage.Expert opinion: The utilization of biological adjuncts for improved repair and regeneration of ankle injuries represents a promising future in our efforts to address difficult clinical problems. The application of concentrated bone marrow and PRP each represents the most widely studied and commonly used injection therapies with early clinical studies demonstrating promising results, research is also being done using other potential therapies such as stem cells and growth factors; further investigation and outcome data are still needed.

Novel Technique for Treatment of Calcaneal Tuberosity Fractures.

Calcaneal tuberosity fractures comprise only 1% to 2% of all calcaneal fractures. Treatment of these injuries has traditionally included open reduction and internal fixation with various means including lag screws, suture anchors, and K-wires. This article reports on a series of cases treated with excision of the tuberosity fragment with repair of the Achilles tendon supplemented by a flexor hallucis longus tendon transfer.

Using cement plugs in soft tissue infection and osteomyelitis.

Operative foot and ankle osteomyelitis is challenging for orthopedic surgeons because of the area's unique anatomy, high trauma incidence, local and systemic disease effects, and often limited space. Standard treatment includes aggressive operative debridement with local and systemic antibiotic administration to control infection. Dead space management is critical yet technically demanding. The authors report a modified antibiotic cement bead therapy technique in which antibiotic sticks, minnows, and mushroom-shaped plugs are used to strike a balance between the stability of the load-bearing unit and radical removal of infection to preserve a functional foot. Three cases are presented.

An analysis of the Orthopaedic In-Training Examination rehabilitation section.

OBJECTIVE: One subject tested by the Orthopaedic In-Training Examination (OITE) is rehabilitation. Our purpose was to analyze the OITE's rehabilitation section to (1) identify the rehabilitation subjects that are tested, (2) evaluate trainee performance on this section, and (3) evaluate the literature cited for this section as an aide to the trainee preparation for future OITE examinations. DESIGN: This study included OITE examinations from 2004 through 2009. The rehabilitation sections of these examinations were analyzed for content, type of questions asked (taxonomy 1: direct recall; taxonomy 2: diagnosis; taxonomy 3: evaluation/decision making and development of a treatment plan), and literature cited. The mean score in the rehabilitation section of the OITE from 2004 to 2009 was also evaluated, and literature citations were tabulated. SETTING: Orthopaedic surgery residency. RESULTS: In the 2004-2009 OITE examinations, a total of 1619 questions were administered, of which 53 (3.3%) related to rehabilitation. The most common rehabilitation questions assessed knowledge of prosthetic/orthotics (20.8%) and neuro-orthopedics (20.8%). Other questions addressed amputation (18.9%), physical therapy treatment and outcomes (18.9%), rehabilitation terminology (9.4%), and spinal cord injury (7.7%). Most frequently, the questions evaluated the trainee's direct recall of the subject (51%), evaluation/decision making and development of a treatment plan (30.1%), and diagnosis (18.9%). The mean score in the rehabilitation section of the OITE from 2004 through 2009 was 54.1% (range, 40% to 77.8%). A total of 53 references was used. The 3 most common references were the Journal of Bone and Joint Surgery-American Volume (10), Orthopaedic Knowledge Update (volumes 7 through 9) (8), and Clinical Orthopaedics and Related Research (7). CONCLUSION: To our knowledge, our study is the first to analyze the rehabilitation section of the OITE. Our results will help the trainee prepare for the examination by focusing on the appropriate content and literature.
