New technique for stabilizing intertrochanteric hip fractures
A buttress plate with two superior extensions for auxiliary screw
fixation is helping orthopaedic surgeons at the Hospital for Joint
Diseases stabilize posteromedial fragments in complex intertrochanteric
Total knee arthroplasty improves function, lessens pain in arthritis
A study of 15 patients, average age 56 years, between 1986 and
1995 found total knee arthroplasty improves function and reduces
pain in patients with post-traumatic arthritis.
Manual or motorized distraction offers same results in healing
A study of 70 patients using the same type of fixator for bone
lengthening found that using motorized rather than traditional
manual techniques for limb lengthening does not improve the rate
of bone healing or reduce complications.
Anterior cervical fusion study finds improved results with internal
A review of the medical records of 171 patients found that anterior
cervical spine fusion with rigid internal fixation increases the
incidence of fusion and lowers the complication rate.
Cemented hip replacement relieves pain of juvenile rheumatoid
Cemented total hip replacement reduces pain and improves function
for juvenile rheumatoid arthritis (JRA) patients, according to
a 10-year follow-up study. However, the author said the procedure
should be reserved for only the most severely affected patients
who may be unable to walk and whose pain cannot be relieved by
High surface stress may damage contemporary knee components
A scientific exhibit (S 25) on factors influencing the longevity of ultra high molecular weight polyethylene (UHMWPE) tibial components shows high surface stresses increase the potential for polymer damage and represent an etiological mechanism which catalyzes component wear and debris generation.
Drunk, drugged drivers suffer more serious injuries
Drivers under the influence of alcohol are more severely injured
and have a higher incidence of hip dislocations and fractures
in motor vehicle accidents than drivers who are sober.
Rehabilitation helps older athletes who suffer ACL tears
Athletes over the age of 40 who have anterior cruciate ligament (ACL) reconstruction, followed by a year-long rehabilitation regimen, can expect to return to their previous athletic level and have a lower reinjury risk than patients who are treated nonoperatively according to a study presented Thursday in scientific paper 24.
Spine injuries often more serious than they seem
When it comes to treating patients who have spinal cord injuries, "unfortunately there are no miracles at this time," said Herndon Murray, MD, assistant medical director at the Shepherd Center in Atlanta. "If the spinal cord tissue is injured, we don't have a whole lot we can do."
New fellows urged to keep standards high

Orthopaedists face challenges of aging population
An aging America presents orthopaedic surgeons with an enormous new challenge: how to provide comprehensive musculoskeletal care that will enable elderly patients to remain independent.
Growth factors offer promise for treating orthopaedic problems
Growth factors may one day provide important nonsurgical treatments for orthopaedic conditions, a panel of researchers said Thursday at a press conference held prior to a symposium sponsored by the Orthopaedic Research Society and the Academy.
Hepatitis C correlates with tattoos, IV drug abuse, says study
Orthopaedic surgeons may want to give extra attention to their patients' histories based on the results of a study of the incidence of hepatitis C infection in orthopaedic patients.
Surgical techniques increase success of TKR revision
Total knee replacements are among the most successful procedures. However, many complications can necessitate revision. Preventing failure of primary total knee joint replacements (TKR) and handling these problems when they do occur were the topics of a Thursday symposium on 'Surgical Challenges in Revision Total Knee Replacement.'
Early diagnosis the key to treating osteoarthritis
In recent years new knowledge of cartilage and bone at the molecular level has improved the understanding of mechanisms in tissue breakdown and repair. The study of altered synthesis and breakdown of matrix molecules provides important information on mechanisms in diseases which affect joint structures.
Gamma sterilization increases oxidation, says study
Increasing the success rate of surgical repair using polyethylene tibial components may hinge on uncovering the mechanisms behind delamination and damage.
