Welcome to the world of Taiwan Pediatric Orthopaedic Society (TPOS).
This a small world but it is fun to be here.


TPOS was founded in 1994 and the number of members increased quickly to around 130 by the year 2000. The present of this society was elected every two years. The past presidents include Dr. Chun-Hsiung Shih (1994-1996), Dr. Mathew NF Wang (1996-1998) and Dr. Shier-Chieg Huang (1998-2000).

International Correspondence

Besides these three former presidents, there are two more TPOS members who are also members of Pediatric Orthopaedic Society of North America (POSNA). Dr. Ken N Kuo, who is now a professor of Orthopedic Department in Rush Medical School of Chicago, is an active member of POSNA since 1984 and Dr. Mark CJ Lin, who is now the secretary general of TPOS, is a corresponding member of POSNA since 1993. TPOS became an alliance society of POSNA since 1997 and it is becoming an alliance society of International Federation of Pediatric Orthopaedic Society (IFPOS). TPOS has also close relationship with Pediatric Section of West Pacific Orthopedic Association (WPOA), Japanese Pediatric Orthopedic Association (JPOA) and Korean Pediatric Orthopaedic Society (KPOS).

The Directory Board

The directory board include 15 directorates elected by all members with the term of two years. Among them, the president of this society is elected. The secretary general is nominated by the president elect and the committee members as well as directors are determined by the directory board.

The Academic Conferences

The academic conferences for communication between members and for continued pediatric orthopedic education are held every three months. The January program is usually a local conference in various cities. The April program is the Annual Meeting of TPOS with the meeting place usually in the medical center where the current president of TPOS works for. The July program is a local conference for continued pediatric orthopedic education. The October program is usually a joint conference with the Orthopedic Association of Taiwan, ROC.

The field of Pediatric Orthopaedics

The field of Pediatric Orthopaedics includes a host of challenges owing to the diversity of the problems to which the developing human organism is prone (quoted from Henry LaRocca, 1975).

Children are not just small adults. Their orthopedic problems and treatments are different than those of their parents only because their bodies are growing.

Frequently Asked Questions (FAQ)

What is Pediatric Orthopedics?

Pediatric Orthopedics is the study and treatment of growing bones, joints and muscles. Pediatric Orthopedists use many techniques, including observation of growth, physical therapy, braces and splints, and occasionally surgery to treat various conditions such as congenital deformities, injuries, neurological disorders, and scoliosis. These conditions are discussed in general below, with links being added to more specific information as time goes by.

Variations of Normal Anatomy & Congenital Deformities

Frequently, young children and adolescents have conditions that are variations of normal anatomy. These include children who toe-in or toe-out excessively, children with "bad posture" such as round-back or sway-back, and children who are delayed in learning to walk or have unusual patterns of walking such as "toe walking". Often these problems are variations of normal developmental patterns and do not represent an underlying disease. In such cases, the child's growth and patterns of walking, posture, and muscular development need to be observed over time in order to establish whether the child's growth pattern will return to normal spontaneously.

What is congenital Skeletal Deformity?

A small percentage of children have birth defects. Those defects might be due to genetic disorders or interference of early skeletal development. The defects or failures might be at the period of limb generation, separation, or maturation. They include spinal problems such as spina bifida, apparent limb deformities such as clubfoot, obscure limb deformities such as developmental dysplasia of the hip, or other congentital defects such as polydactyly or syndactyly. Pediatric Orthopedists frequently follow these children through years of growth and into adult life.

What are childhood Injuries?

Children often break bones. With these fractures there is often a potential injury to the growth centers of the skeleton. Pediatric Orthopedists evaluate the child for potential growth problems that may happen after the injury heals and treat growth disturbance if it occurs. Appropriate treatment of fractures, sprains and dislocations can ensure minimal disturbance of function and a quick return to normal childhood growth and activity.

What is Pediatric Sports Injury?

Pediatric Sports Medicine is an important part of health care. Children who engage in activities like soccer, karate, and skateboarding may have acute injuries such as broken bones, sprains, and dislocations. Many times chronic stress injuries occur, such as fractures, tendinitis, and apophysitis. Examples are Little Leaguer's Elbow, Osgood-Schlatter's disease of the knee, and Sever's Disease of the foot. Treatment of these injuries is usually simple and seldom requires surgery. However, adequate knowledge of how to prevent them and how to help them heal smoothly is very crucial for the children's future sports potential.

What is a neuromuscular Disease?

Many patients seen by Pediatric Orthopedists have neurological disorders such as cerebral palsy, spina bifida, or the family of diseases known as muscular dystrophies. Most of these disorders result in muscle imbalance and deformity in the areas involved, such as drop foot, scoliosis, or paralytic clubfoot. Children with cerebral palsy or spina bifida frequently require bracing or surgery to improve their ability to function to their greatest potential. Before best treatments can be planned, motion analysis with the information of the time-distance parameters, kinematics, kinetics, and muscle roles during the gait is very helpful to the pediatric orthopedists.

What are scoliosis and kyphosis?

These conditions are deformities of the spinal column and may occur at any time before or after birth, but are more frequent during the adolescent growth spurt. Scoliosis is curvature of the spine seen in about 5% of teenage girls. Kyphosis is an excessive round-back deformity common in teenagers.

What is leg length discrepancy?

This condition is due to the loss of symmetry of bilateral leg growth. The etiology might be due to congenital defect of one limb, congenital hemihypotrophy or hemihypertrophy, dislocation of unilateral joint (such as DDH), fractures and injuries (especially the growth plate), and many possible diseases. Treatment includes careful observation of the disprepancy during growth and surgical interventions. Surgeries can be done to shorten the long leg or to lengthen the short leg, depending on the preference of the surgeons, the expectation of the patient, and the safety of the procedures.
