: We analysed scaphoid deformity as a result of surgical treatment of scaphoid fracture nonunion and assessed the deformity associated with a dorsal intercalated segmental instability pattern of carpal malalignment. A total of 45 patients who were treated for scaphoid fracture nonunion were included in the study. The height-to-length ratio of the scaphoid was measured on computed tomographic images and used to assess scaphoid deformity. Carpal malalignment was quantified based on the radio-lunate angle...

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...

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...

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...

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...

In scaphoid fractures, delayed diagnosis and nonunion are fairly common as a result of several factors, including the difficulty of radiographic diagnosis of non-displaced fractures and underestimation of the injury by the patient. Main factors to consider when deciding treatment are the type of fracture and fracture stability. In the stable nonunion (Type D1 according to the Filan and Herbert classification, or linear type of Ikeda's classification), percutaneous screw fixation without bone graft is recommended...

BACKGROUND: Despite being an effective analgesic for children with fractures, some clinicians may avoid prescribing ibuprofen due to its potentially harmful effect on bone healing. OBJECTIVE: To determine if exposure to ibuprofen is associated with an increased risk of bone healing complications in children with fractures. METHODS: We performed a retrospective study of children aged 6 months to 17 years who presented to the pediatric emergency department (PED) with a fracture of the tibia, femur, humerus, scaphoid, or fifth metatarsus and who followed up with the orthopedic service...

BACKGROUND: Scaphoid fractures represent the most common carpal fractures and are often problematic and frequently lead to nonunion with osteoarthritis and collapse of the wrist. The reasons for the nonunion are manifold. Therefore, the main goal of diagnosis and therapy of acute fractures is to achieve bony union and to restore the anatomic shape of the scaphoid. In the long run, only this can preserve the normal function of the wrist. METHODOLOGY: The given recommendations are based on the new S3-level guideline of the AWMF (Association of the Scientific Medical Societies)...

OBJECTIVE: The purpose of this study is to report the union rate and time to union for acute non-displaced scaphoid waist fractures treated with a short arm thumb spica cast. METHODS: A database was searched (2006-2013) to identify acute undisplaced scaphoid waist fractures. Cases that were not given a trial of casting were excluded (n=33). X-rays, CT scans and health records for each patient were reviewed to extract data. RESULTS: 172 patients met inclusion criteria...

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...

BACKGROUND: Avascularity of fragments is a common problem in treatment of scaphoid nonunion. Therefore, vascularised bone grafts have gained increasing importance. Especially the free vascularised femoral trochlea flap has become the subject of special interest because of its particular characteristics in the last few years. OBJECTIVES: Indications for and the technique of free vascularised corticocancellous as well as osteocartilagineous femoral trochlea flap are reported according to the author's practice combined with an evaluation of these methods considering current literature...

The clinical relevance of scaphoid bone fractures is reflected by their high incidence, accounting for approximately 60 % among carpal fractures and for 2-3 % of all fractures. With adequate therapy most scaphoid bone fractures heal completely without complications. Insufficient immobilization or undiagnosed fractures increase the risk of nonunion and the development of pseudarthrosis.X-ray examination enables initial diagnosis of scaphoid fracture in 70-80 % of cases. Positive clinical symptoms by negative x‑ray results require further diagnostics by multi-slice spiral CT (MSCT) or MRI to exclude or confirm a fracture...

BACKGROUND: Operative treatment of the scaphoid nonunion includes avascular corticocancellous and cancellous bone grafts and increasingly the use of vascular pedicled and free vascular corticocancellous grafts. Especially the latter require a fair amount of operative expertise and experience in microsurgical techniques. OBJECTIVE: Which criteria lead to the decision for or against an avascular graft used for reconstruction of scaphoid nonunion? Is our current classification system of a scaphoid pseudarthrosis able to illustrate our diagnostic potential in a way that makes us refer to operative procedures? METHODS: Evaluation of current literature and expert opinions RESULTS: Avascular bone grafts show a high union rate as long as a sufficient vascularisation of the remaining fragments is present...
