Zur erweitrten Indikationsstellung der Herbert-Schrauben-Osteosynthese
1995
Since 1984 the typical headless double threaded Herbert/Whipple screw is known in managing scaphoid fractures and scaphoid non-unions. We resume technical, biomechanical and histological aspects to point out advantages and disadvantages of this osteosynthesis. Our case review of 39 patients illustrate the same good results as achieved in treating scaphoid injuries, when using the Herbert/Whipple screw of a larger diameter for expanded indications other than scaphoid fractures, such as humeral- or radial-head fractures, Jones fractures and others.
Chondrocostal grafting for lateral osteochondral injury of the metacarpal head
2020
Abstract Osteochondral injuries of the metacarpal head require anatomical restoration to prevent limitations in range of motion and osteoarthritis. Osteochondral bone grafting is a viable option, especially in younger patients. Central injuries allow for different types of grafting, but when the injured area is on the lateral portion of the metacarpal head, the graft must include both a cortical and a cartilaginous portion. We present here the pearls and pitfalls in the surgical technique of chondrocostal grating from the 6th rib and an example of its use within a case of comminuted fracture of the metacarpal head. This technique provides a graft with cortical bone that allows for a stable …
Chondrodysplasia punctata, tibia-metacarpal (MT) type.
1990
We describe 7 patients with a new form of chondrodysplasia punctata. Its principal clinical manifestations are flat midface and nose, short limbs, and otherwise normal development. Consistent radiologic manifestations in the newborn infant are discrete calcific stippling, coronal clefts of vertebral bodies, short tibiae, and shortness of the 2nd and 3rd metacarpal bones. Radiologic findings in the older child include shortness of tibiae and the 3rd and 4th metacarpals.
Posterior perilunate carpal dislocation associated with a multifragmentary distal radius fracture.
2009
Summary Dorsal perilunate wrist dislocations are rare. Associated carpal bones or radial styloid process fractures can occur and be included in the current classifications. The authors report an unusual association of dorsal perilunate wrist dislocation with a multifragmentary distal radius fracture. Such traumatic entity has never been previously described. Poor functional outcome may justify the inclusion of associated complex forearm bone fractures in wrist dislocation classifications.
Unusual manifestation of an osteoid osteoma of the capitate.
1999
A case of osteoid osteoma of the capitate in a 29-year-old male is reported. The patient suffered from unspecific clinical findings and a 3-year history of uncharacteristic wrist pain. Conventional radiographs of the wrist revealed a circumscribed sclerosis in the proximal part of the capitate bone beside a diffuse demineralisation of the carpal bones. Magnetic resonance imaging demonstrated a circumscribed, tumorous lesion with marked enhancement after IV administration of contrast agent and a highly calcified nidus, which was sharply demarcated by a small rim of granulation tissue from the surrounding spongious bone. Based on MRI findings, the diagnosis of an osteoid osteoma was establish…
Giant enchondroma recurrence of the proximal phalanx of the fifth finger: A case report
2020
Enchondroma (EC) is a benign and cartilage-forming tumor that causes intramedullary lesions. Moreover, EC is the most common bone tumor in the phalanges and metacarpal bones of the hand, deforming the structure and causing pain and functional limitation. The management of this neoplasia is the surgical treatment and the approach that is well-accepted consists in the curettage followed by the void augmentation with biological or synthetic fillers. The results from surgery are usually good and the recurrence rate is low (2-15%). In this article we report a case of EC recurrence of the proximal phalanx of the fifth finger of the hand after curettage and grafting. The patient was treated with t…
