Brachydactyly- MedGen UID:
- 67454
- •Concept ID:
- C0221357
- •
- Congenital Abnormality
Digits that appear disproportionately short compared to the hand/foot. The word brachydactyly is used here to describe a series distinct patterns of shortened digits (brachydactyly types A-E). This is the sense used here.
Short thumb- MedGen UID:
- 98469
- •Concept ID:
- C0431890
- •
- Congenital Abnormality
Hypoplasia (congenital reduction in size) of the thumb.
Broad hallux- MedGen UID:
- 401165
- •Concept ID:
- C1867131
- •
- Finding
Visible increase in width of the hallux without an increase in the dorso-ventral dimension.
Growth abnormality- MedGen UID:
- 808205
- •Concept ID:
- C0262361
- •
- Finding
Short stature- MedGen UID:
- 87607
- •Concept ID:
- C0349588
- •
- Finding
A height below that which is expected according to age and gender norms. Although there is no universally accepted definition of short stature, many refer to "short stature" as height more than 2 standard deviations below the mean for age and gender (or below the 3rd percentile for age and gender dependent norms).
Waddling gait- MedGen UID:
- 66667
- •Concept ID:
- C0231712
- •
- Finding
Weakness of the hip girdle and upper thigh muscles, for instance in myopathies, leads to an instability of the pelvis on standing and walking. If the muscles extending the hip joint are affected, the posture in that joint becomes flexed and lumbar lordosis increases. The patients usually have difficulties standing up from a sitting position. Due to weakness in the gluteus medius muscle, the hip on the side of the swinging leg drops with each step (referred to as Trendelenburg sign). The gait appears waddling. The patients frequently attempt to counteract the dropping of the hip on the swinging side by bending the trunk towards the side which is in the stance phase (in the German language literature this is referred to as Duchenne sign). Similar gait patterns can be caused by orthopedic conditions when the origin and the insertion site of the gluteus medius muscle are closer to each other than normal, for instance due to a posttraumatic elevation of the trochanter or pseudarthrosis of the femoral neck.
Osteoarthritis- MedGen UID:
- 45244
- •Concept ID:
- C0029408
- •
- Disease or Syndrome
Osteoarthritis (OA) is a degenerative disease of the joints characterized by degradation of the hyaline articular cartilage and remodeling of the subchondral bone with sclerosis (Meulenbelt et al., 2006). Clinical problems include pain and joint stiffness often leading to significant disability and joint replacement. Osteoarthritis exhibits a clear predilection for specific joints; it appears most commonly in the hip and knee joints and lumbar and cervical spine, as well as in the distal interphalangeal and the first carpometacarpal (base of thumb) and proximal interphalangeal joints of the hand; however, patients with osteoarthritis may have 1, a few, or all of these sites affected (Stefansson et al., 2003). According to a conservative estimate, greater than 70% of the population of the United States at age 65 years is affected by the disease, reflecting its age dependence.
Genetic Heterogeneity of Susceptibility to Osteoarthritis
Susceptibility to osteoarthritis has been associated with variation in other genes: OS2 (140600) with variation in the MATN3 gene (602109) on chromosome 2p24; OS3 (607850) with variation in the ASPN gene (608135) on chromosome 9q22; and OS5 (612400) with variation in the GDF5 gene (601146) on chromosome 20q11.
Other susceptibility loci for osteoarthritis have been mapped to chromosomes 2q33 (OS4; 610839) and 3p24 (OS6; 612401).
Osteoarthritis of hip- MedGen UID:
- 14530
- •Concept ID:
- C0029410
- •
- Disease or Syndrome
Osteoarthritis of the hip joint.
Osteochondritis dissecans- MedGen UID:
- 10494
- •Concept ID:
- C0029421
- •
- Disease or Syndrome
A joint disorder caused by blood deprivation in the subchondral bone causing the subchondral bone to die in a process called avascular necrosis. The bone is then reabsorbed by the body, leaving the articular cartilage it supported prone to damage. The result is fragmentation (dissection) of both cartilage and bone, and the free movement of these osteochondral fragments within the joint space, causing pain and further damage.
Frontal bossing- MedGen UID:
- 67453
- •Concept ID:
- C0221354
- •
- Congenital Abnormality
Bilateral bulging of the lateral frontal bone prominences with relative sparing of the midline.
Accelerated skeletal maturation- MedGen UID:
- 154262
- •Concept ID:
- C0545053
- •
- Finding
An abnormally increased rate of skeletal maturation. Accelerated skeletal maturation can be diagnosed on the basis of an estimation of the bone age from radiographs of specific bones in the human body.
Lumbar hyperlordosis- MedGen UID:
- 263149
- •Concept ID:
- C1184923
- •
- Finding
An abnormal accentuation of the inward curvature of the spine in the lumbar region.
Exostoses- MedGen UID:
- 257035
- •Concept ID:
- C1442903
- •
- Disease or Syndrome
An exostosis is a benign growth the projects outward from the bone surface. It is capped by cartilage, and arises from a bone that develops from cartilage.

- 867418
- •Concept ID:
- C4021790
