To realize the new concept of biological internal fixation the limited contact dynamic compression plate was developed. It minimizes vascular damage to the plated bone segment. It should lead to a more versatile and efficient application of internal fixation using plates.

The value of intramedullary reaming in the treatment of chronic osteomyelitis of long bones.
Between 1985 and 1990 25 patients with chronic osteomyelitis (osteitis) of long bones were treated by intramedullary reaming. In most cases the aetiology of the osteomyelitis was posttraumatic. 22 of these patients who had undergone intramedullary reaming at least 6 months ago were evaluated. ⋯ One patient produced a little extraosseous sequestrum 3 months after the operation but since then has had no recurrence. The purpose of this study is to propose intramedullary reaming as an excellent treatment for chronic osteomyelitis of long bones and show the pathophysiological background that led to this modality.

Review Case ReportsIrreducible dorsal dislocation of the metatarsophalangeal joint of the hallux.
Irreducible dorsal dislocation of the metatarsophalangeal joint of the hallux is a rare injury. A case is presented and the literature is reviewed, with emphasis on pathomechanics and treatment alternatives.

Randomized Controlled Trial Clinical TrialArthroscopic cartilage debridement by excimer laser in chondromalacia of the knee joint. A prospective randomized clinical study.
A new operative technique in arthroscopic treatment of chondromalacia using ultraviolet laser systems is introduced. The postoperative results are evaluated in a prospective and randomized clinical trial. One hundred and forty patients stage II or III chondromalacia according to Outerbridge were randomly assigned to arthroscopic operation using either laser or mechanical instruments. ⋯ In the short-term follow-up laser surgery gave superior results in regard to reducing pain (P less than 0.05) and leading to a lower incidence of reactive synovitis (P less than 0.01). No difference was found in respect of disability and functional impairment. Our results lead to the conclusion that arthroscopic laser application seems to be a successful procedure in the treatment of degenerative cartilage disorders, providing precise ablation of tissue without significant thermal damage to the remaining cartilage.

ReviewClinical experience with titanium implants, especially with the limited contact dynamic compression plate system.
AO/ASIF with its collaborating laboratories has developed cold worked pure titanium material for implants with an outstanding biocompatibility. The first prospectively controlled clinical series dates back to 1966 and was reported to be most successful. Pure titanium also became the material of choice for implants to be used in patients suffering from metal allergy. ⋯ Pilot clinics started to implant titanium LC-DCP in 1987, and already 271 plates have been used, mainly for the treatment of fresh fractures. Some 57 plates have so far been removed. The preliminary results are most favourable; they confirm especially the outstanding biocompatibility of pure titanium.
