Latissimus Dorsi Tendon Transfer and Superior Capsular Reconstruction for Irreparable, Posterosuperior Rotator Cuff Tears.

Background: The purpose of this study was to compare latissimus dorsi tendon transfer (LDTT) and arthroscopic superior capsular reconstruction (SCR) to determine if one is superior to the other regarding improvement in range of motion (ROM) or patient-reported outcomes (PROs).

Methods: A multicenter, retrospective cohort study was conducted on 43 patients with an irreparable, posterosuperior rotator cuff tear who underwent either LDTT or SCR. Preoperative and postoperative forward flexion and external rotation, as well as PROs including ASES, VAS, and SSV, were assessed.

Prevalence of Carpal Tunnel Syndrome in a Hand Surgeon's Practice.

Additional methods of diagnosing carpal tunnel syndrome (CTS) are increasingly being investigated, such as ultrasound or diagnostic tools such as carpal tunnel syndrome 6 (CTS-6), and the sensitivity and specificity of these tests are determined by the pretest probably and thereby the prevalence of a condition. It is critical that the prevalence used in these calculations accurately reflects the population undergoing these tests for a true assessment of their quality. Orthopaedic surgeons and, specifically, upper extremity specialists are most often studying these diagnostic methods, and given referral patterns, these physicians likely have a greater prevalence of CTS in their clinics than previously published for only the general population (5%).

A Prospective Comparison of Diagnostic Tools for the Diagnosis of Carpal Tunnel Syndrome.

Purpose: Nerve conduction studies (NCS), CTS-6, Wainner, Kamath, and Lo are diagnostic tests that are used to diagnose carpal tunnel syndrome (CTS). To our knowledge, no study has compared the sensitivity and specificity of these 5 tests with one another. The purpose of this study is to compare NCS, CTS-6, Wainner, Kamath, and Lo using clinical diagnosis by a hand fellowship-trained orthopedic surgeon as reference standard.

NSAID use in intervertebral disc degeneration: what are the effects on matrix homeostasis in vivo?

Background Context: Non-steroidal anti-inflammatory drugs (NSAIDs) are a widely used treatment for low back pain (LBP). Literature on NSAID use in articular cartilage has shown detrimental effects; however, minimal data exist to detail the effects of NSAIDs in intervertebral disc degeneration (IDD). As IDD is a major cause of LBP, we explored the effects of indomethacin, a commonly used NSAID, on disc matrix homeostasis in an animal model of IDD.

Thumb Injuries in Athletes.

Thumb injuries are common in athletes and present a challenging opportunity for upper extremity physicians. Common injuries include metacarpal base fractures (Bennett and Rolando types), ulnar and radial collateral ligament injuries, dislocation of the carpometacarpal and metacarpophalangeal joints, and phalanx fractures. This review, although not exhaustive, highlights some of the most common thumb injuries in athletes.

Correlating Median Nerve Cross-sectional Area With Nerve Conduction Studies.

Purpose: To determine whether there is a correlation between the cross-sectional area (CSA) of the median nerve, as measured using ultrasound, and the distal motor and/or sensory latencies as measured on nerve conduction studies.

Methods: Patients with clinical signs and symptoms of carpal tunnel syndrome were prospectively enrolled in this study. Subjects underwent ultrasound measurement of the CSA of the median nerve at the carpal tunnel inlet by a fellowship-trained hand surgeon, followed by nerve conduction studies (NCS) by a certified electrodiagnostic technician who was blinded to the results of the ultrasound examination.

Staged treatment of high energy midfoot fracture dislocations.

Background: Staged care with interval external fixation is a successful established treatment strategy for high energy periarticular fractures with often extensive soft tissue damage such as the tibial plateau and plafond. The aim of the current study was to determine whether staged care of high energy midfoot fracture/dislocation with interval external fixation prior to definitive open reconstruction in the polytraumatized patient was both safe and efficacious.

Methods: One hundred twenty-three patients were operated on for high energy midfoot fracture/dislocation during the 8-year study period.

Molecular basis of intervertebral disc degeneration and herniations: what are the important translational questions?

Background: Intervertebral disc degeneration is a common condition with few inexpensive and effective modes of treatment, but current investigations seek to clarify the underlying process and offer new treatment options. It will be important for physicians to understand the molecular basis for the pathology and how it translates to developing clinical treatments for disc degeneration. In this review, we sought to summarize for clinicians what is known about the molecular processes that causes disc degeneration.
