Surgeon operates to rescue chimp with rare deformity

19.05.2008
An orthopaedic surgeon at the University of Liverpool has performed a groundbreaking operation on a chimp in Cameroon to correct a deformity more commonly seen in dogs.

The three year-old chimp called Janet was rescued from the Cameroon pet trade last year and now lives in a chimpanzee reserve supported by the Cameroon Wildlife Aid Fund. Janet was unable to climb and had difficulty walking because a bone in her forearm - the ulna - had stopped growing.

It is thought that her condition, known as angular limb deformity, is a congenital problem, but could also have been caused or aggravated by being chained at the wrist by traders. This forced the arm’s radius to grow in a circular manner making her arm severely bent. Vets have seen the deformity in dogs before but never in chimpanzees and were called in to assess Janet’s condition.

Rob Pettitt, orthopaedic surgeon at the University’s Small Animal Teaching Hospital, said: “Surgery to correct the condition in dogs is less complex than the procedure in chimps. In dogs bone tissue stops growing early in life, so once the limb is straightened there is little time for the deformity to recur and interfere with bone development. In chimps and humans however, the areas of growth at the end of long bones can stay open for years, so there is plenty of time for the condition to return. We therefore sought the advice of specialists at Robert Jones and Agnes Hunt orthopaedic hospital at Oswestry - to make sure we protected any growth left in Janet’s limb.

“The first step was to remove the far end of the ulna, which had become compacted due to the continued growth of the radius. A 14mm triangular section of bone was then removed from the radius in order to straighten the limb and a bone plate was inserted into the radius to secure the two ends of the bone.”

Selling chimps as pets is illegal but rife on the black market in Cameroon. Adult chimpanzees are slaughtered for their meat and the young chimps are then taken away and sold as pets.

Rachel Hogan, manager of the chimpanzee reserve in Cameroon, said: “Janet is recovering well and has now rejoined her group at the reserve. She has been undergoing physiotherapy so that she can learn how to use the limb properly. She is made to grip a ball a few times a day and undo bottle tops to exercise her wrist. The X-rays show the surgery was a complete success.”

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
