BACKGROUND: Although subspecialist orthopaedic surgeons usually request Magnetic Resonance Arthrogram (MRA) examinations, some orthopaedic surgeons may request this examination for a body part that is different from their subspecialty. The purpose of the study is to compare the MRA and the clinical findings in the subspecialist and non-subspecialist groups. METHOD: Retrospective analysis of MRA examinations over a 6-month period. Findings were compared with the clinical information...

The purpose of this study was to review the clinical results of carpal ligaments injuries with scaphoid nonunion. We hypothesized that scaphoid nonunion with carpal ligament injury is associated with clinical result. We retrospectively reviewed 60 cases of -Herbert screw fixation with bone graft for scaphoid nonunions. Scapholunate (SL) and lunotriquetral (LT) ligaments lesions were confirmed by arthroscopy. Approximately half of the nonunion scaphoid cases had carpal ligaments injuries. At final follow-up evaluation, wrist function as evaluated by the Mayo wrist score was excellent in 34 patients, good in 16 patients, fair in 8 patients, and poor in 2 patients...

AIM: To review the results of our experience with the Medartis Aptus plating system for four corner arthrodesis of the wrist, which uses a combination of compression screws and variable angle locking screws. METHODS: We reviewed the results of 17 procedures in 16 patients that underwent scaphoid excision and four corner fusion using the Medartis Aptus system between May 2010 and June 2014. The primary outcome measure was radiographic and clinical union. RESULTS: The mean clinical follow up time was 20...

BACKGROUND: Nonunion of scaphoid proximal pole fractures presents a challenging management dilemma to hand surgeons. This problem is further complicated in the uncommon concurrence of scapholunate (SL) ligament disruption. CASE DESCRIPTION: A 39-year-old male patient presented with new-onset wrist pain following a remote history of a proximal pole scaphoid fracture sustained as a teenager, which was treated nonoperatively. Six months before presentation, the patient sustained a fall while snowboarding...

PURPOSE: A high incidence of nonunion and relatively poor outcomes with prior fixation techniques has precluded scapholunate (SL) arthrodesis as a standard treatment for SL instability. Our purpose was to determine the impact on range of motion (ROM) of simulated SL arthrodesis via headless screw fixation. METHODS: We performed baseline wrist ROM for 10 cadaveric wrists using a standardized mounting-and-weights system. Extension, flexion, radial deviation, ulnar deviation, dart-thrower's extension, and dart-thrower's flexion were assessed...

The complex interaction of the carpal bones, their intrinsic and extrinsic ligaments, and the forces in the normal wrist continue to be studied. Factors that influence kinematics, such as carpal bone morphology and clinical laxity, continue to be identified. As imaging technology improves, so does our ability to better understand and identify these factors. In this review, we describe advances in our understanding of carpal kinematics and kinetics. We use scapholunate ligament tears as an example of the disconnect that exists between our knowledge of carpal instability and limitations in current reconstruction techniques...

INTRODUCTION: Arthroscopic resection of dorsal wrist ganglia has become a well-accepted practice. However, there is a paucity of results on occult ganglia in the literature. The purpose of this study is to evaluate the subjective outcomes of occult dorsal wrist ganglion cysts resected arthroscopically, and to identify and examine intraarticular findings and relate them to pre-operative MRI findings and histologies. MATERIALS AND METHODS: In 39 patients, 40 wrists were treated with arthroscopic resection of an occult dorsal wrist ganglion...

BACKGROUND: Isolated capitate-trapezoid coalition is a rare form of carpal coalition with few cases described in the literature and a little insight as to how it should be addressed clinically. CASE DESCRIPTION: We present a case of bilateral, a complete osseous carpal coalition between capitate and trapezoid discovered in the setting of atraumatic, symptomatic scapholunate dissociation in a 59-year-old, right-handed mechanic. LITERATURE REVIEW: Published reports of capitate-trapezoid coalition are rare, and there is no consensus as to whether this abnormality is a symptomatic pathology or incidental finding...

Scapholunate (SL) ligament injury is among the most common injuries of the intrinsic ligaments of the carpus. Arthroscopic treatment in complete and nonacute injuries has had poor results. These cases have typically been treated using open surgical techniques that require a broad dorsal approach and produce soft tissue impairment, which leads to reduced wrist mobility. The development of wrist arthroscopy techniques has allowed the treatment of complete and nonacute injuries of the SL ligament, without the disadvantages of open surgery, respecting the soft tissues and avoiding injury of the posterior interosseous nerve, in an attempt to preserve the proprioception of the wrist and the secondary dorsal stabilizers...

BACKGROUND AND AIMS: Patients with acute or chronic wrist pain often undergo wrist arthroscopy for evaluation of chondral and ligamentous abnormalities. The purpose of this study was to compare findings of wrist arthroscopy with cone beam computed tomography arthrography and magnetic resonance arthrography. MATERIALS AND METHODS: Altogether, 21 patients with wrist pain underwent cone beam computed tomography arthrography, magnetic resonance arthrography, and wrist arthroscopy...

BACKGROUND: Limited wrist arthrodesis with scaphoid excision is a useful treatment for scapholunate advanced collapse (SLAC) of the wrist. Multiple Kirschner wires were originally used for internal fixation of the four carpal bones, however long-term cast immobilization, pin tract infection, and hardware removal are still problematic. We introduce and evaluate the clinical outcomes of an internal fixation technique; triangle fixation for four-corner fusion, using three headless screws, as an alternative to conventional multiple Kirschner wires for the treatment of SLAC wrist...

This article demonstrates a technique for the treatment of scaphoid fracture waist and proximal pole nonunions with avascular necrosis using a free vascularized medial femoral condyle flap. We present our surgical technique and representative case examples in which the scapholunate ligament, a key structure required to preserve carpal kinematics, is spared.

The dorsal capsulo-scapholunate septum (DCSS) is an anatomic structure linking the scapholunate ligament and the dorsal capsule of the wrist. It should be a predynamic scapholunate stabilizer. The authors, using their experience for the extrinsic ligaments testing, suggest an arthroscopic testing of the DCSS. The status could be graded in 4 stages according to the trampoline aspect and to the fiber attachment. They report a preliminary study on a series of 53 arthroscopies made between January 2014 and December 2015 with evaluation of scapholunate ligament instability and DCSS laxity...

PURPOSE: The purpose of this study was to assess characteristics of radiocarpal arthrofibrosis after intra-articular distal radius fractures (DRF). PATIENTS AND METHODS: In this study 20 patients who underwent wrist arthroscopy at the time of implant removal after volar plating for intra-articular DRF were included retrospectively. The direction of fibrous tissue formation (FTF) and its rigidity were investigated. The findings were correlated to the course of intraarticular fracture lines seen in the preoperative CT, patient age and AO fracture types...

UNLABELLED: This case describes an early controlled mobilization (ECM) approach that uses dart-throwing motion (DTM) with a twist orthoses as an alternative to immobilization for conservative management of a minimally displaced and intra-articular distal radius styloid fracture with an associated scapholunate ligament injury in a 47-year-old female health care administrator (JP). Pain-free active DTM began at day 10 (5 times/d) with a dynamic DTM with a twist orthosis worn during the day from weeks 3 to 6...
