Nicholas Pulos, Brent R DeGeorge, Alexander Y Shin, Marco Rizzo
BACKGROUND: The purpose of this study was to determine whether prominent radial shaft screws in volar locked plating of distal radius fractures increase the risk of tendon irritation, tendon rupture, or hardware removal. METHODS: Patients who underwent volar locked plating of distal radius fractures from April 2002 to March 2016 with at least 6 months of follow-up were evaluated. Variables examined included demographics, extensor tendon irritation, extensor tendon rupture, and hardware removal...

BACKGROUND: Minimally invasive dorsal cheilectomy (MIDC) for hallus rigidus is gaining in popularity. The optimal position for the stab incision for MIDC is dorsomedial to allow an ergonomic sweeping movement of the burr, potentially putting the dorsomedial cutaneous nerve (DMCN) to the hallux at risk. We aimed to quantify the risk of using this minimally invasive technique with a cadaveric study. METHODS: A total of 13 fresh-frozen cadaveric specimens amputated below the knee were obtained for this study...

The camel digits have a complex structure with tendons, joints and ligaments. The objective of the study was to determine the anatomical features of the metatarsophalangeal joint and its puncture site in dromedary camel using anatomical dissection, radiography, computed tomography (CT) bone and soft tissue window scans and 3D reconstruction render volume of CT. The study used six adult camels of both sexes (three males and three females), aged 9-15 years (Mean ± SD equal 11.80 ± 2.59 years). The camel fetlock possesses two metatarsophalangeal joints, left and right ones...

Achondroplasia is a genetic mutation of fibroblast growth factor receptor resulting in impaired growth plate development in long bones due to lower collagen turnover. Despite the characteristic shorter stature and lower strength in Achondroplasic groups, little is known of the tendon mechanical properties under loading. The aim of this study was therefore to conduct a between measure design of patella tendon (PT) mechanical properties (stress, strain, stiffness and Young's Modulus) in 10 men with Achondroplasia (22 ± 3 years) and 17 male controls (22 ± 2 years)...

BACKGROUND: Musculoskeletal models do not include patient-specific muscle forces but rely on a scaled generic model, with muscle forces left unscaled in most cases. However, to use musculoskeletal simulations to inform clinical decision-making in children with cerebral palsy (CP), inclusion of subject-specific muscle forces is of utmost importance in order to represent each child's compensation mechanisms introduced through muscle weakness. RESEARCH AIM: The aims of this study were to (i) evaluate if maximum isometric muscle forces (MIMF) in musculoskeletal models of children with CP can be scaled based on strength measurements obtained with a hand-held-dynamometer (HHD), (ii) evaluate the impact of the HHD based scaling approach and previously published MIMF scaling methods on computed muscle forces during gait, and (iii) compare maximum muscle forces during gait between CP and typically developing (TD) children...

BACKGROUND: Disruption of the extensor mechanism after total knee arthroplasty (TKA) is debilitating, and the reported results of numerous reconstructive options have varied. We previously reported the early results of 13 patients who underwent reconstruction of the extensor mechanism with use of Marlex mesh. The purpose of the current study was to assess results in a larger cohort of patients, with an emphasis on the survivorship of the mesh, clinical results, and complications. METHODS: During the period of 2000 to 2015 at a single tertiary care academic institution, 77 patients (77 TKAs) underwent reconstruction with use of Marlex mesh for an extensor mechanism disruption (27 quadriceps tendon disruptions, 40 patellar tendon disruptions, and 10 patellar fractures)...

Dynamic splinting is a well-known method for maintaining finger movement after ruptures of the extensor tendons. We describe a simple, inexpensive and easy-to-construct modification of a dynamic splint, called the "Sparti" splint, suitable for a six-week period of rehabilitation of injured extensor tendons in zones V-VII.

PURPOSE: Fascia flaps are a preferred method to reconstruct the soft tissue envelope of the hand when a thin and pliable flap is required to cover exposed tendons. The aim of this study was to report on our experience with the fascia-only reversed posterior interosseous artery flap. Contrary to commonly used fascia flaps, this flap does not require free tissue transfer. METHODS: In this retrospective review, 5 patients were identified, each of whom underwent soft tissue reconstruction with a reversed posterior interosseous artery fascia flap...

Avulsion of the tibial tubercle is an uncommon injury that occurs in the young athlete, resulting from an eccentric contraction of the extensor mechanism with the leg fixed to the ground. Concomitant injuries to the patellar tendon are very rare, with few cases reported in the literature. The authors present a case of a 15-year-old basketball player who suffered an avulsion of the tibial tubercle associated with complete distal rupture of the patellar tendon while training. It was treated with open reduction of the tibial fragment and reconstruction of the patellar tendon with mini-anchors and cannulated screws, as well as hamstring autograft tendon reinforcement...

Closed rupture of the thumb flexor tendon pulleys is rare. Although anatomical and biomechanical studies have exposed the roles played by the pulleys in flexor pollicis longus (FPL) function, no standardized surgical management has yet been defined, in contrast to situations where pulley reconstruction is required in the fingers. We describe a case of rupture of the three pulleys in the thumb that probably occurred after violent thumb grasp during childbirth in the absence of any other trauma. We reconstructed the A1 pulley only using an extensor retinaculum graft because no remnants of the native pulleys were present...

BACKGROUND: Injections into the tendinous portion of the common extensor origin are a common intervention in the treatment of Lateral Elbow Tendinopathy (LET). Clinical trials report a heterogeneous selection of injectate volumes and delivery techniques, with systematic reviews finding no clear consensus. The aim of this study was to assess the intratendinous distribution and surrounding tissue contamination of ultrasound-guided injections into the Common Extensor Tendon (CET) of the elbow...

Ken Shirakawa, Masahiko Shirota
BACKGROUND: Surface replacement arthroplasty (SRA) through a volar approach for the proximal interphalangeal (PIP) joint can preserve the integrity of the extensor tendon, which allows early range of motion (ROM) exercise postoperatively. However, a few reports have shown that the PIP ROM tends to decline with longer follow-up. The goal of this study is to assess the results of at least 5 years of follow-up of SRA through a volar approach and also to investigate the cause of deterioration of ROM with time after SRA through this approach...

Tendon allografts, when autograft options are limited or when obtaining an autograft is not aligned with the patients' best interest, play an important role in tendon and ligament reconstruction. To minimize the risk of infectious disease transmission tissue banks perform screening tests and the allografts cleaned are sterilized. The current study examines and compares the initial mechanical properties and histological appearance of supercritical CO2 (SCCO2 )-treated and gamma-irradiated porcine extensor tendons...

Hitoshi Yoshimura, Tadashi Okano, Kentaro Inui, Hiroaki Nakamura
Intravesical bacillus Calmette-Guerin (BCG) therapy is an effective and safe immunotherapy for superficial bladder cancer. However, reactive arthritis (ReA) is reported as an adverse event in about 0.5-1% of patients receiving intravesical BCG therapy. ReA is known as a kind of spondyloarthritis, the main pathological finding of which is enthesitis. Here we report a patient with ReA induced by intravesical BCG therapy for bladder cancer, in whom the diagnosis of ReA was supported by ultrasonographic findings of enthesitis and synovitis...
