Injury to the anterior cruciate ligament (ACL) is regarded as critical to the physiological kinematics of the femoral-tibial joint, its disruption eventually causing long-term functional impairment. Both the initial trauma and the pathologic motion pattern of the injured knee may result in primary degenerative lesions of the secondary stabilisers of the(More)
Interbody fusion after anterior discectomy may lead to acceleration of degenerative changes at adjacent levels. Although the posterior approach preserves the motion segment, decompression of the nerve root is indirect if "hard disc prolaps" is the main cause. Recently, a technique of microsurgical anterior cervical foraminotomy for the treatment of(More)
INTRODUCTION Exact anatomical description of the proximal radius is imperative for the development of radial head prostheses. The purpose of this study was to measure the anatomical parameters of the radial head. METHODS Optosil imprints of 18 pairs of proximal radii fixed with formalin were taken. All possessed their native cartilage joint surface free(More)
This study investigates differences in the anatomy of male and female knee joints to contribute to the current debate on sex-specific total knee implants. Morphometric data were obtained from 60 human cadaver knees, and sex differences were calculated. All data were corrected for height, and male and female specimens presenting with an identical length of(More)
The relationship between the fibers of the interosseous membrane and the muscle fibers of the deep extensor and flexor muscles was investigated on the basis of 33 forearms. The angle between muscle and membrane fibers was determined radiologically in the dorso-ventral and radio-ulnar planes. The spatial angle of origin can be determined immediately in areas(More)
The anatomical relationships of the greater occipital nerve (GON) to the semispinalis capitis muscle (SCM) and the trapezius muscle aponeurosis (TMA) were examined to identify topographic landmarks for use in anesthetic blockade of the GON in occipital neuralgia. The course and the diameter of the GON were studied in 40 cadavers (29 females, 11 males), and(More)
The first tarsometatarsal (TMT) joint has a complex role in regulating joint pressure in the midfoot. Despite its importance, there have been only a few studies of the functional morphology and biomechanical function of this joint. Here we report about the densitometric pattern of the subchondral bone layer of the articulating elements of the human first(More)
For osteosynthesis in the epiphyseal region of long bones, specialized screw types are available to achieve a better purchase in cancellous bone. Typically, the cancellous bone screw has a large outer thread diameter with a relatively small core diameter and a great pitch. Due to its dimensions, this screw type is not suited for the cancellous bone areas in(More)
Pain and tenderness on the palmar and ulnar aspects of the wrist in the area of the pisiform bone is fairly common. Chronic pain in the pisiform area may be due to tendinitis of the insertion of the flexor carpi ulnaris, bony fractures or osteoarthrosis of pisotriquetral joint which is the second most common degenerative arthritis in wrist after the(More)
The metacarpophalangeal (MCP) joints II to V of 21 hands were examined radiologically and arthrographically. Different recesses of the joint cavity were demonstrated both radiologically and macroscopically, with a dominating dorsal recess. The existing forms of the dorsal recess were one-tailed, two-tailed, three-tailed, symmetric and cap-like.(More)
