Visualization and reduction of a mensical capsular junction tear in the knee: an arthroscopic surgical technique.

Meniscal injuries commonly occur concomitantly with anterior cruciate ligament (ACL) injuries. Although many types of meniscal injuries have been described in the literature, there has not been much focus on meniscal capsular junction (MCJ) tears. This lack of attention is concerning given that, in a survey of 67 orthopedic surgeons, 88% indicated that MCJ tears could be a source of chronic pain.

Total wrist replacement: a retrospective comparative study.

Purpose Total wrist arthroplasty (TWA) is an evolving procedure for the treatment of arthritis of the wrist joint. The purpose of this study is to compare outcomes of three different total wrist implants. Methods A retrospective review of the Biaxial, Universal 2, and Re-Motion total wrist arthroplasties was performed.

Vitamin D deficiency in cord plasma from multiethnic subjects living in the tropics.

Background: Vitamin D deficiency is commonly reported in high-latitude areas and in dark-pigmented individuals. However, nothing is known about vitamin D in cord blood from multiethnic subjects living in the tropics.

Objective: Our study objective was to determine the prevalence of vitamin D deficiency in summer and winter in cord blood from multiethnic individuals in Hawai'i where sufficient sun irradiance occurs year-round for cutaneous vitamin D production.

In vivo pilot study evaluating the thumb carpometacarpal joint during circumduction.

Background: Analysis of arthrokinematics may have clinical use in the diagnosis of dynamic instability of the thumb and wrist. Recent technological advances allow noninvasive, high-resolution imaging of skeletal (thumb and carpal bones) structures during motion.

Questions/purposes: The primary purpose of this study is to define the arthrokinematics, estimated joint contact patterns, and distribution ratios of the carpometacarpal joint of the thumb using four-dimensional CT (three-dimensional CT + time) and registration algorithms.

Compound f: the history of hydrocortisone and hand surgery.

Hydrocortisone (cortisol) is used daily in the practice of medicine and hand surgery. It has an effective use in a number of orthopedic conditions, including tendinitis, tenovaginitis, bursitis, carpal tunnel syndrome, and joint inflammation. But are surgeons aware of how this important pharmaceutical agent was discovered and prepared for clinical trial and who was responsible for its first clinical application? How did medical doctors determine that, like penicillin, cortisone and its derivative hydrocortisone would have such a life-changing effect on certain medical conditions? The purpose of this review is to relate the story of the development of cortisone (Compound E) and hydrocortisone (Compound F) and how both influenced the practice of hand surgeons in the treatment of rheumatoid arthritis and related inflammatory conditions.

Long-term outcomes of proximal interphalangeal joint surface replacement arthroplasty.

Background: Surface replacement arthroplasty is a reconstructive alternative for the treatment of pain and deformity due to osteoarthritis and rheumatoid arthritis of the proximal interphalangeal joint of the finger. This retrospective study was performed to examine long-term outcomes of proximal interphalangeal joint prosthetic surface replacement with a proximal cobalt-chromium (CoCr) and distal ultra-high molecular-weight polyethylene component over thirty years at a single institution.

Methods: Sixty-seven prostheses were implanted in forty-seven patients between 1974 and 2007.

Delayed treatment of elbow pain and dysfunction following Essex-Lopresti injury with metallic radial head replacement: a case series.

Background: Chronic longitudinal radioulnar dissociation has been associated with unpredictable and generally unfavorable outcomes. Metallic radial head replacement may address this treatment deficiency.

Methods: Eight patients were treated with a metallic radial head replacement for chronic longitudinal radioulnar dissociation.

Radial head fractures and the role of radial head prosthetic replacement: current update.

Radial head fractures are often secondary to a direct axial force, such as that involved in motor vehicle accidents and falls on an outstretched hand. The Hotchkiss-modified Mason classification is an excellent assessment tool in that it provides commonly accepted direction regarding treatment. For more unstable, comminuted displaced radial head fractures that cannot be reconstructed, replacement of the radial head is warranted.

Clinical comparison of arthroscopic versus open repair of triangular fibrocartilage complex tears.

Purpose: To determine whether traumatic triangular fibrocartilage complex (TFCC) tears treated by arthroscopic repair have improved functional outcome scores, range of motion, grip strength, and pain relief compared with those repaired using an open surgical technique.

Methods: From 1997 to 2006, 75 patients had repair of traumatic TFCC tears. Thirty-six patients had arthroscopic TFCC repair, and 39 patients had open repair.
