Background Wrist arthroscopy is now a routine procedure, regarded as safe. Complications are reported in the literature as being rare and mostly minor. Purpose The two goals of this study were to evaluate the incidence and nature of complications based on a very large multicenter retrospective study, and to investigate about a potential learning curve. Methods The authors sent a detailed questionnaire to all members of the European Wrist Arthroscopy Society (EWAS), inquiring about the number and types of complications encountered during their practice of wrist arthroscopy, and about their experience with the technique...

Purpose The terminal branches of the posterior interosseous nerve (PIN) are the main articular branch on the dorsal aspect of the wrist. Its relationship to dorsal wrist arthroscopic portals has not yet been elucidated. The purpose of this study was to quantitatively describe the anatomical relationships between the dorsal wrist arthroscopic portals and the PIN. Methods Dorsal wrist arthroscopic portals were established in 28 cadaver extremities, after which the limbs were dissected. Measurements were taken from the portals to the PIN...

Ulnar styloid impaction syndrome involves repetitive friction between an excessively long ulnar styloid and the carpus, resulting in chondromalacia, synovitis, and pain. The arthroscopic diagnosis, evaluation, and management of this syndrome are not well characterized. We present a patient with chronic wrist pain of unknown origin, culminating with arthroscopic findings demonstrating substantial loss of articular cartilage on both the lunate and triquetrum. The patient successfully underwent operative ulnar styloid excision, ultimately resolving chronic wrist pain symptomology...

Background Scapholunate (SL) interosseus ligament injuries detected at an early stage could allow the surgeon to prevent progression through the spectrum of injury that leads to instability, and eventually osteoarthritis. We contend that early instability following injury can be detected by visualizing the relative motions and distances between the involved carpal bones (scaphoid and lunate) during wrist movement in vivo. The purpose of this study is to demonstrate the utility of dynamic CT (i.e., 4DCT) in diagnosing SL interosseus ligament injuries in two patients with clinical suspicion of SL interosseus ligament injury during flexion-extension (FE), radial-ulnar (RU) deviation, and dart thrower's (DT) motions...

Background Single-photon emission computed tomography and computed tomography (SPECT/CT) is a hybrid diagnostic imaging modality that allows clinicians to integrate their diagnostic evaluations and deliver a definitive diagnosis in musculoskeletal disorders. Specifically, in identification of osseous pathology, the conventional bone scan delivers greater specificity compared with magnetic resonance imaging (MRI). However, use of SPECT/CT enhances the sensitivity and specificity. Use of this modality denotes the possibility to specify the lesion more accurately and precisely while grading the activity according to osseous structural changes...

Range of motion and stability are important outcome parameters to assess function of the distal radioulnar joint (DRUJ), in particular pronation, supination, and weight-lifting capacity. The DRUJ semiconstrained implant developed by Scheker et al is intended to reproduce all the functions of the triangular fibrocartilage complex and the DRUJ. The aim of the study was to investigate the subjective, clinical, and radiographic results in 10 patients after primary implantation of the semiconstrained DRUJ arthroplasty following DRUJ derangement and painful instability, with an average follow-up of 3 years with a special focus on the complications...

Purpose Ulna-shortening osteotomy is one of the most established and most frequent operations in hand surgery. However, bone union is not always achieved and the use of plates implies potential risks and problems. The traditional points of criticism are the duration of bone healing, the incidence of nonunion, and the necessity of hardware removal due to the soft tissue irritation by the plate or the screws. These shortcomings have been addressed by an increasing standardization of the procedure and finally specific instruments and implants...

Purpose In the presence of early osteoarthritis, changes to the trapeziometacarpal joint (TMJ) often result in pain and is associated with joint instability and a tendency of dorsoradial subluxation. In these instances, arthroscopy may be indicated to: (1) assess the extent of cartilage disease and the laxity of ligaments and to (2) treat TMJ instability. The purpose of our study was to biomechanically analyze which ligaments are the primary stabilizers of the TMJ. Methods Overall, 11 fresh-frozen human cadaver specimens were dissected and attached to a testing device with the thumb positioned in neutral abduction, neutral flexion, and neutral opposition...

Background An accessory slip arising from the extensor carpi ulnaris (ECU) tendon that inserts on the fifth metacarpal bone has been identified. We describe the frequency of this accessory slip arising from the ECU tendon and provide both qualitative and quantitative description of the slip via cadaveric examination. Methods Fifty (28 males and 22 females) cadaveric upper extremity specimens were examined after loupe-aided dissection of the dorsoulnar wrist and hand with identification of the ECU tendon...

Background Scapholunate advanced collapse and scaphoid nonunion advanced collapse result in high morbidity and pose significant challenges for active patients. Multiple treatment options have been proposed to yield satisfactory results; however, restoration of physiological wrist motion remains an issue. Questions/Purposes The objective of this study was to compare wrist mobility after four different treatment methods for grade III wrist collapse: (1) no treatment, (2) scaphoidectomy and lunate-capitate arthrodesis, (3) scaphoidectomy, lunate-capitate arthrodesis, and triquetrum-hamate arthrodesis, and (4) scaphoidectomy, lunate-capitate arthrodesis, and triquetrum excision...

Background Previous authors have reported pisotriquetral pain and subsequent pisiform excision following partial or total wrist fusion in patients with scapholunate advanced collapse (SLAC). Prior studies have not considered the potential role of SLAC biomechanics on pisotriquetral osteoarthritis (PT OA) development preoperatively. Purpose To determine the prevalence and severity of PT OA in patients with SLAC as compared with a control population. Patients and Methods Magnetic resonance imaging (MRI) studies of 24 patients with SLAC wrist and 24 sex- and age-matched control patients were analyzed...

The assessment and management of Kienböck Disease (KD) has always been a conundrum. The Lichtman classification has traditionally been used to guide treatment based on imaging. Arthroscopy provides a direct visualization of the articular surface, allows probing of the surfaces, and enables minimally invasive techniques to be performed. The Lichtman-Bain classification is a new classification that takes into account the osseous, vascular, and cartilage aspects of the lunate and the secondary effects on the wrist...

Kienböck disease is a condition that typically occurs in the "at-risk" patient, in the "at-risk" aspect of the proximal condyle of the "at-risk" lunate. In the active male, repetitive loading causes the stress fracture that commences in the single layer proximal subchondral bone plate. The lunate fracture commences at the point the lunate cantilevers over the edge of the distal radius, and then takes on the shape of the radius. We postulate that the stress fracture violates the parallel veins of the venous subarticular plexus-leading to localized venous hypertension and subsequent ischemia and edema of the fatty marrow...

Coronal (or frontal plane) fractures of the scaphoid are distinctly uncommon. There are few published reports of coronal fractures of the scaphoid. This fracture is often missed on the initial X-ray films. A high index of suspicion should exist when there is a double contour of the proximal scaphoid pole on the anteroposterior X-ray view. A computed tomography scan is integral in making the diagnosis. Early recognition is key in salvaging the scaphoid fracture and in preventing articular damage. Level of Evidence IV...

BACKGROUND: The safety of surgical approaches for single- versus double-incision carpal tunnel release in association with distal radius open reduction and internal fixation remains controversial. PURPOSE: The purpose of this study was to identify critical structures to determine if a single-incision extension of the standard flexor carpi radialis (FCR) approach can be performed safely. METHODS: Nine cadaveric arms with were dissected under loupe magnification, utilizing a standard FCR approach...

Simultaneous volar dislocations of the second through fifth carpometacarpal joints are rare injuries, usually a result of high-energy trauma to the hand. The literature regarding this topic is sparse and consists primarily of case reports. We present a case associated with median nerve contusion that was treated with open reduction and pin fixation. The median nerve injury resolved without incident, and the pins were removed at 10 weeks without loss of reduction. Three years postoperatively, the patient was without pain and had excellent use of his hand without strength or motion deficit...
