Question: Hip scoring is a procedure used to determine the degree of an abnormal formation of the hip socket, that can cause crippling lameness and what other joint disorder? 

Context paragraphs:
Hip resurfacing: Hip resurfacing has been developed as a surgical alternative to total hip replacement (THR).  The procedure consists of placing a cobalt-chrome metal cap, which is hollow and shaped like a mushroom, over the head of the femur while a matching metal cup (similar to what is used with a THR) is placed in the acetabulum (pelvis socket), replacing the articulating surfaces of the patient's hip joint and removing very little bone compared to a THR.  When the patient moves the hip, the movement of the joint induces synovial fluid to flow between the hard metal bearing surfaces lubricating them when the components are placed in the correct position.  The surgeon's level of experience with hip resurfacing is most important; therefore, the selection of the right surgeon is crucial for a successful outcome.  Health-related quality of life measures are markedly improved and patient satisfaction is favorable after hip resurfacing arthroplasty.

Sacroiliac joint dysfunction: Sacroiliac joint dysfunction, also called sacroiliac joint disorder, sacroiliac joint disease, sacroiliac joint syndrome or sacroiliac syndrome, or "sacroilliac dysfunction and instability", generally refers to pain in the sacroiliac joint region that is caused by abnormal motion in the sacroiliac joint, either too much motion or too little motion.  It typically results in inflammation of the sacroiliac joint, and can be debilitating.

Legg–Calvé–Perthes disease: Legg–Calvé–Perthes disease (LCPD) is a childhood hip disorder initiated by a disruption of blood flow to the ball of the femur called the femoral head.  Due to the lack of blood flow, the bone dies (osteonecrosis or avascular necrosis) and stops growing.  Over time, healing occurs by new blood vessels infiltrating the dead bone and removing the necrotic bone which leads to a loss of bone mass and a weakening of the femoral head.  The bone loss leads to some degree of collapse and deformity of the femoral head and sometimes secondary changes to the shape of the hip socket.  It is also referred to as idiopathic avascular osteonecrosis of the capital femoral epiphysis of the femoral head since the cause of the interruption of the blood supply of the head of the femur in the hip joint is unknown.

Abnormality (behavior): Abnormality (or dysfunctional behavior), in the vivid sense of something deviating from the normal (c.f. Norm (social)) or differing from the typical (such as an aberration), is a subjectively defined behavioral characteristic, assigned to those with rare or dysfunctional conditions.  Behavior is considered abnormal when it is atypical, out of the ordinary, causes some kind of impairment, or consists of undesirable behavior.  Often what is abnormal, or what is not abnormal, is determined by an individual's culture.  The definition of what abnormal behavior is a contentious issue in abnormal psychology.  It is an assumption that abnormal behavior is a disorder that has a physical cause, specifically that it is related to the physical structure of the brain.  A diagnosis of a mental disorder describes a patient who has a medical condition and the doctor makes a judgment that the patient is exhibiting abnormal behavior.  The distinction being that mental disorders describe processes, not people.

Hip score: Hip scoring is a procedure used to determine the degree of hip dysplasia in dogs and other animals and reporting the findings in a standard way.

Palatoplasty: Palatoplasty is a surgical procedure used to correct or reconstruct the palate in a person with a cleft palate.  The basic goals of the procedure are to close the abnormal opening between the nose and mouth, to help the patient develop normal speech, and to aid in swallowing, breathing and normal development of associated structures in the mouth.  Any person with any degree of a cleft palate is a candidate for palatoplasty.  The procedure is usually performed on infants.  The ideal age for the patient is between six and twelve months of age.  If the surgery is carried out much beyond three years of age, speech development may not be optimal.  80% of the time, development of the palate and speech is normal after only one procedure.

Heparin-induced thrombocytopenia: Heparin-induced thrombocytopenia (HIT) is the development of thrombocytopenia (a low platelet count), due to the administration of various forms of heparin, an anticoagulant.  HIT predisposes to thrombosis (the abnormal formation of blood clots inside a blood vessel) because platelets release microparticles that activate thrombin, thereby leading to thrombosis.  When thrombosis is identified the condition is called heparin-induced thrombocytopenia and thrombosis (HITT).  HIT is caused by the formation of abnormal antibodies that activate platelets.  If someone receiving heparin develops new or worsening thrombosis, or if the platelet count falls, HIT can be confirmed with specific blood tests.

Cystinosis: Cystinosis is a lysosomal storage disease characterized by the abnormal accumulation of the amino acid cystine.  It is a genetic disorder that typically follows an autosomal recessive inheritance pattern.  It is a rare autosomal recessive disorder resulting from accumulation of free cystine in lysosomes, eventually leading to intracellular crystal formation throughout the body.  Cystinosis is the most common cause of Fanconi syndrome in the pediatric age group.  Fanconi syndrome occurs when the function of cells in renal tubules is impaired, leading to abnormal amounts of carbohydrates and amino acids in the urine, excessive urination, and low blood levels of potassium and phosphates.

Hip dysplasia (canine): In dogs, hip dysplasia is an abnormal formation of the hip socket that, in its more severe form, can eventually cause crippling lameness and painful arthritis of the joints.  It is a genetic (polygenic) trait that is affected by environmental factors.  It is common in many dog breeds, particularly the larger breeds, and is the most common single cause of arthritis of the hips.

Slipped capital femoral epiphysis: Slipped capital femoral epiphysis (SCFE or skiffy, slipped upper femoral epiphysis, SUFE or souffy, coxa vara adolescentium) is a medical term referring to a fracture through the growth plate (physis), which results in slippage of the overlying end of the femur (epiphysis).  Normally, the head of the femur, called the capital, should sit squarely on the femoral neck.  Abnormal movement along the growth plate results in the slip.  The femoral epiphysis remains in the acetabulum (hip socket), while the metaphysis (end of the femur) move in an anterior direction with external rotation.
