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...

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)...

BACKGROUND: Early destruction of the wrist in rheumatoid arthritis is common and often progressive. Even in times of improved and standardized medical treatment this cannot always be prevented. OBJECTIVES: A limited range of motion, pain, reduced grip-force, and aesthetic deficits of the wrist can impair the daily life of patients. There is an additional risk for destruction of the surrounding soft tissue and adjoining joints of the upper extremity. RESULTS: Destruction of wrist in rheumatoid arthritis is multifactorial and is localized in many different structures of the wrist...

The scaphoid is biomechanically and clinically of great importance for function of the wrist. In the literature, its anatomy and biomechanics are clearly underrepresented as well as underestimated. In the following review the scaphoid will be presented in more detail, according to recent information and findings. Not only will the origin of the name and the history of previous names, such as cotyloid or navicular, be introduced, but also for the first time in medical literature the significant phylogeny and ontogeny of the scaphoid will be shown...

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...

PURPOSE: The optimal management of undisplaced scaphoid fractures remains controversial. A systematic review was conducted to assess the outcomes of acute, undisplaced scaphoid fractures managed with cast immobilization versus percutaneous or miniopen screw fixation in terms of time to return to work (RTW), time to union, and morbidity. METHODS: PubMed MEDLINE, Ovid MEDLINE, EMBASE, SCOPUS, and Cochrane electronic databases were searched over the period 1974 to 2015...

At the wrist, kinematic coupling (the relationship between flexion-extension and radial-ulnar deviation) facilitates function. Although the midcarpal joint is critical for kinematic coupling, many surgeries, such as four-corner fusion (4CF) and scaphoid-excision four-corner fusion (SE4CF), modify the midcarpal joint. This study examines how 4CF and SE4CF influence kinematic coupling by quantifying wrist axes of rotation. Wrist axes of rotation were quantified in eight cadaveric specimens using an optimization algorithm, which fit a two-revolute joint model to experimental data...

INTRODUCTION: Perilunate and lunate dislocations are uncommon high energy injuries and have extensive soft tissue, cartilaginous and bony damage. The most common pattern is trans-scaphoid perilunate fracture dislocation which constitutes approximately 50% of these injuries. Unusual injury pattern like Scaphocapitate syndrome can occur with fracture through scaphoid waist and capitate that rotates the proximal capitate 180° so that its proximal articular surface points distally. With this case report, we would like to present a novel presentation of an uncommon wrist injury...

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...

: Radial styloid pointing due to spur formation is considered an early sign of osteoarthritis, but is sometimes difficult to distinguish from normal anatomic variation. In this pathoanatomical study we used three-dimensional imaging techniques to evaluate quantitatively whether the styloid size is larger in wrists with scaphoid non-union than in healthy wrists. We compared these findings with duration of the non-union and with the scaphoid non-union advanced collapse classification, which was based on radiographic assessment of the general level of wrist osteoarthritis...

Primary sarcomas of the thumb metacarpal are rare malignant lesions. Surgical treatment involves amputation versus tumor resection with thumb reconstruction. If complete tumor resection is possible, thumb preservation may be considered, as the thumb is vital to hand function. Following tumor resection, previous reports have described graft reconstruction with fusion to the trapezium or scaphoid. We present two cases of sarcoma necessitating resection of the thumb metacarpal that were reconstructed with an arthrodesis of the proximal phalanx to the second metacarpal shaft...

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...

This study correlated morphologic abnormalities of idiopathic carpal tunnel syndrome (CTS) with the severity of CTS using 3-T magnetic resonance imaging (MRI). The relationship of the severity of CTS and the cross-sectional area of the median nerve (CSA) was assessed at several levels. Seventy wrists of 35 patients (27 women and 8 men) with unilateral idiopathic CTS underwent nerve conduction study and 3-T MRI of the wrist. The CSA at 4 levels (distal radioulnar joint, body of scaphoid, tubercule of scaphoid, and hook of hamate) and the thickness of the transverse carpal ligament at 3 levels in both affected and unaffected hands were measured using 3-T MRI and correlated with the severity of CTS assessed with distal motor latency...
