Extensor tendon ruptures due to volar plating in distal radius fractures have mostly been described in relation with technique failures such as screw prominence and drill penetration. We report the case of a 71-year-old female with a C2 distal radius fracture with severe dorsal metaphyseal comminution. The patient underwent surgical treatment with reduction of the large fragments and fixation with a volar locking plate; the small dorsal metaphyseal nonarticular fragments were not reduced. Six months later, the patient developed extensor digitorum communis (EDC) rupture and extensor indicis proprius (EIP) laceration in coincidence with the dorsal comminution turned into a bony spur...

This study assessed the comprehensive incidence of tendon rupture following volar locking plate (VLP) surgery for a large number of patients with distal radius fractures (DRFs) at multiple facilities in one prefecture, Japan. During the 4-year period, 2787 patients with DRFs underwent fixation using VLP. The overall incidence rates of rupture of the FPL, the extensor pollicis longus, the flexor digitorum profundus of the index finger, and the extensor digitorum communis were 0.35% (10 patients), 0.29% (8 patients), 0...

REVIEW
Sami H Tuffaha, W P Andrew Lee
Proximal interphalangeal joint (PIPJ) flexion contracture is a challenging and often frustrating problem. Treatment of PIPJ contracture begins with conservative measures. With good compliance and prolonged use, favorable results can be achieved using these modalities. For contractures that fail to respond to conservative treatment, surgical intervention can be considered. The affected structures that can be released during surgery include the accessory collateral ligaments, volar plate, checkrein ligaments, retinacular ligaments, and the flexor and extensor tendons...

In spite of the more popular volar approach for plating of distal radius fractures (DRFs), there are still indications for dorsal plating and even combined dorsovolar plating in complex DRFs. Dorsal plating carries a concern for complications such as tenosynovitis, extensor tendon adhesions, and delayed extensor tendon ruptures. These risks can be minimized by use of modern low-profile plates and the use of an extensor retinaculum flap to cover the distal plate and screws. We describe the technique of the dorsal retinaculum flap for dorsal plating of DRFs...

BACKGROUND: Complications related to extensor tendons have begun to increase with the use of volar plates in the treatment of distal radius fractures. In this study, we aimed to compare four-plane radiography and ultrasonography in the evaluation of dorsal cortex screw penetration following volar plate fixation. METHODS: We recruited 47 patients (33 males, 14 females, mean age 37.4 years; range 18-58 years). To evaluate dorsal screw penetration in all patients, we performed radiographs at 45° pronation, 45° supination and obtained dorsal tangential graphs at maximum palmar flexion, and a wrist lateral radiograph...

The dorsal-metacarpal-artery (DMCA) flap in its standard or extended version is considered as the working horse to cover dorsal soft tissue finger defects with exposed extensor tendon or bone. We hereby present a clinical case of an 80-year-old male patient who is right-handed and sustained a soft tissue defect of the proximal dorsal aspect of his left 5th finger and the postoperative outcome employing a modified transposition flap. The double-pedicled DMCA flap (dpDMCA flap) of the hand poses in adequate clinical scenarios a comparably fast and safe solution to cover dorsal finger defects extending just distal to the PIP joint...

[Purpose] To clarify the motion-plane dependency of the range of dart throw motion and the effects of tendon action due to long finger flexors and extensors during the motion. [Subjects and Methods] Forty healthy subjects attended the experiment, and the active range of wrist motion in seven motion planes was measured with an originally designed apparatus. [Results] The reliability of the measurement was acceptable. The range of dart throw motion depended on the motion planes, with a maximum at around the motion plane of 45° from the sagittal plane (45° of pronation)...

Jun Wan, Can Zhang, Hong-Bo He
BACKGROUND: Resection of proximal fibular osteosarcoma involving the posteromedial aspect of the fibula is challenging. Reconstruction using a gastrocnemius flap may result in significant lateral instability and abnormal knee movement. Furthermore, postoperative gait may be disturbed by foot drop resulting from scarification of the common peroneal nerve. METHODS: Between January 2011 and December 2013, five patients with proximal fibular osteosarcoma were treated via the double-approach procedure using en bloc resection without a gastrocnemius flap...

Non-invasive assessment of spinal circuitry in humans is limited, especially for Ib pathways in the upper limb. We developed a protocol in which we evoke the H-reflex in flexor carpi radialis (FCR) by median nerve stimulation and condition it with electrical stimulation above motor threshold over the extensor carpi radialis (ECR) muscle belly. Eighteen healthy adults (eight male, ten female) took part in the study. There was a clear reflex facilitation at 30 ms inter-stimulus interval (ISI), and suppression at 70 ms ISI, which was highly consistent across subjects...

Walid Ben-Nafa, Wendy Munro
INTRODUCTION: Lateral epicondylitis is a common musculoskeletal disorder of the upper limb. Corticosteroid injection has been widely used as a major mode of treatment. However, better understanding of the pathophysiology of the disease led to a major change in treating the disease, with new options including platelet-rich plasma (PRP) are currently used. Objectives/research aim: To systematically evaluate the effect of corticosteroid versus PRP injections for the treatment of LE. HYPOTHESIS: PRP injections provide longer-term therapeutic effect and less rate of complications compared to corticosteroid injection...

BACKGROUND: The Sauvé-Kapandji (SK) procedure is one of several surgical options in the treatment of distal radioulnar disorders by osteoarthritis (OA) and rheumatoid arthritis (RA). While satisfactory postoperative clinical results were obtained in most cases, instability of the proximal ulnar stump and radioulnar convergence are the most common complications. Minami et al. have developed a modification of the SK procedure that maintains the transverse diameter of the distal radioulnar joint and stabilizes the proximal ulnar stump, using a half-slip of the extensor carpi ulnaris tendon...

Tendons transfer forces produced by muscle to the skeletal system and can therefore have a large influence on movement effectiveness and safety. Tendons are mechanosensitive, meaning that they adapt their material, morphological and hence their mechanical properties in response to mechanical loading. Therefore, unloading due to immobilization or inactivity could lead to changes in tendon mechanical properties. Additionally, ageing may influence tendon biomechanical properties directly, as a result of biological changes in the tendon, and indirectly, due to reduced muscle strength and physical activity...

The Sauvé-Kapandji procedure is a reliable option for patients with various disorders of the distal radioulnar joint (DRUJ). However, postoperative pain over the proximal ulnar stump frequently develops during forearm rotation or when lifting heavy objects, although many clinically satisfactory results have been reported. This stump pain has been suggested to result from dynamic instability of the proximal ulnar stump. Several types of tenodesis have recently been performed simultaneously with the Sauvé-Kapandji procedure to stabilize the proximal ulnar stump and thus relieve the associated pain...

The contributions of fibre atrophy, fibre loss, in situ specific force and voluntary activation to weakness in sarcopenia remain unclear. To investigate, forty older (20 women; age 72±4yrs) and 31 younger adults (15 women, age 22±3yrs) completed measurements. The knee extensor maximal voluntary torque (MVC) was measured as well as voluntary activation, patella tendon moment arm length, muscle volume and fascicle architecture to estimate in situ specific force. Fibre cross-sectional area (FCSA), fibre numbers and connective tissue contents were also estimated from vastus lateralis biopsies...
