The authors present a case of isolated scaphoid dislocation in a 40-year-old male that was undiagnosed for 2 months. The patient was treated by open reduction, Kirschner wire fixation, interosseous ligament repair using a suture anchor and Blatt's dorsal capsulodesis. At 6 years followup, his radiographs of wrist showed a normal carpal alignment with a scapholunate gap of 3 mm and no evidence of avascular necrosis (AVN) of the scaphoid.

In this literature review, the authors analyse the prognostic factors in the curative treatment of scaphoid non-unions. The main negative prognostic factors are smoking, the time elapsed since the fracture, and avascular necrosis of the proximal fragment. If the latter is present, the revascularization by a pedicle or microsurgical bone autograft is probably the treatment of choice. In non-unions without evidence of osteonecrosis, vascularized bone grafts are probably not superior to conventional bone grafts, which can presently be performed under arthroscopic control, with minimal morbidity...

The purpose of this study was to assess the inter-observer and intra-observer reproducibility of the interpretation of CT arthrography and plain X-rays for scapholunate advanced collapse (SLAC), scaphoid non-union advanced collapse (SNAC) and scaphoid chondrocalcinosis advanced collapse (SCAC) wrist conditions, as well as the clinical relevance of these imaging modalities. The CT and X-rays images were reviewed twice in a blinded and randomized manner by two experienced orthopedic surgeons specialized in hand surgery, two orthopedic surgery residents and two experienced radiologists specialized in bone and joint imaging...

Although isolated distal radius and scaphoid fractures are common, the combination of both fractures is rare, with a reported frequency between 0.5% and 6%. This rarity is probably due to the fact that both fractures share the same injury mechanism. Published studies are limited, but most patients are males in their 40s and the injuries are typically due to high-energy trauma. In most studies, the distal radius fracture is displaced while the scaphoid fracture is not. Since the functional outcome depends of the severity of the radius fracture, we believe, as do others, that it is logical to fix both fractures with stable devices (i...

Scapholunate advance collapse (SLAC) and Scaphoid nonunion advance collapse (SNAC), are the two most common patterns of postraumatic wrist arthritis. SLAC wrist develops after attenuation, either traumatically or atraumatically, of the scapholunate ligament. Atraumatic causes of SLAC wrist include calcium pyrophosphate dehydrate deposition disease, reumathoid arthritis, neuropathic diseases, and b2-microglobulin asociated amyloid deposition diseases. On the other hand, SNAC wrist develops following a scahpoid fracture that has progressed to a nonunion...

BACKGROUND: The I-Space is a radiological imaging system in which Computed Tomography (CT)-scans can be evaluated as a three dimensional hologram. The aim of this study is to analyze the value of virtual reality (I-Space) in diagnosing acute occult scaphoid fractures. METHODS: A convenient cohort of 24 patients with a CT-scan from prior studies, without a scaphoid fracture on radiograph, yet high clinical suspicion of a fracture, were included in this study. CT-scans were evaluated in the I-Space by 7 observers of which 3 observers assessed the scans in the I-Space twice...

A 51-year-old female patient presented with a carpal giant cell tumor (GCT) of the right capitate bone. The lesion was initially misdiagnosed as having an osteomyelitis. First, the diagnosis of a benign GCT was confirmed by histological examination. Second, an intralesional curettage and packing of the cavity with cancellous iliac crest bone grafts combined with a fusion of the third carpometacarpal (CMC III) joint were carried out. Third, due to a secondary midcarpal osteoarthritis and a secondary scaphoid nonunion, the CMC III joint fusion plate was removed and the midcarpal joint completely excised...

PURPOSE: Scaphoid nonunion can occur in both non-operative and operatively treated scaphoid fractures. Without treatment, this can lead to a predictable pattern of carpal collapse and degenerative arthritic change and patients can experience both pain and functional loss in the early and late phases of progression. An operative technique with a high success rate for union is important. This paper describes a technique for treatment of scaphoid nonunion with K-wire fixation and iliac crest cancellous bone graft...

Scaphoid fracture is the most common carpal fracture of the upper extremity and a significant proportion of these can eventually progress to nonunion. Excision of pseudoarthrosis and fibrous scar tissue at the nonunion site is regarded as one of the important steps in management of scaphoid nonunions. We describe a technique of internal bone grafting, where curettage of the nonunion site was performed through a drill hole in the scaphoid and bone graft was packed through this same hole before fixation with a headless compression screw...

: The purpose of this study was to determine the functional, radiographic, and subjective outcome of the authors' technique of four-corner arthrodesis using the en bloc excised scaphoid as the principal donor bone graft coupled with Kirschner wire fixation. The study comprised 40 consecutive patients with progressive Stage II and III scapholunate advanced collapse or scaphoid nonunion advanced collapse deformities. Preoperative and postoperative range of motion, grip strength, carpal height, and Michigan Hand Outcomes Questionnaire responses were assessed with a mean follow-up of 4...

Fusion of the carpal bones is a rare anatomical abnormality, caused by a defect in the separation and cavitation during embryonic development. It has a prevalence of about 0.1% and most of the time, patients do not present with symptoms. Symptoms are usually caused by wear and tear of the ligaments attached to the fused carpal fragments. We present a case in which a woman aged 36 years experiences pain caused by a lunato-triquetral instability which in turn is caused by a unilateral complete fusion of the scaphoid and the trapezium...

Scaphoid nonunion represents a challenging problem that leads to disability if neglected. Vascularized bone grafts are proposed to augment the local biology and increase the likelihood of union but long-term outcomes are sparse. In this work, we present the mid- to long-term outcome of 140 scaphoid nonunions managed with vascularized bone grafts from the distal radius. Sixteen patients underwent concomitant closed wedge osteotomy of the distal radius because of arthritic changes. There were 130 males and ten females, with mean time from injury to surgery 3...

Surgical management of carpometacarpal osteoarthritis may use many techniques. Pi2 (pyrocarbon interposition implant) arthroplasty is one possible solution after total trapeziectomy. The present study assessed clinical and radiological results in Pi2 arthroplasty at a minimum 10years' follow-up. Forty-two consecutive cases underwent surgery between March 2003 and April 2005; 29 were followed up for a mean of 125.49months (10.5years). A total of 96.6% of patients were very satisfied or satisfied. Range of motion improved, especially in opposition (mean Kapandji score, 9...

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 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...

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...

We report the case of a 15-year-old boy with combined fractures of the scaphoid, capitate, and hamate that represents a rare variation of the well-known Fenton's syndrome. Fixation was performed for the unstable fractures of the scaphoid and capitate with the use of cannulated Herbert screws and K‑wires respectively. K‑wires were removed after 6 months, with subsequent physiotherapy. After 6 months, CT confirmed complete consolidation of the two surgically treated carpal fractures and the conservatively treated fracture of the hamate...
