OTA - RehabilitationWhich is/are true of the healing process of fractures:
1. there are three major phases of fracture healing
2. there are two major phases of fracture healing
3. reparative Phase includes granulation tissue formative
4. reparative Phase includes lamellar bone deposition - ANS-14
Which is/are true of the healing process of fractures:
1. the healing process is mainly determined by the periosteum
2. the periosteum is one source of precursor cells which develop into chondroblasts and
osteoblasts that are essential to the healing of bone
3. the bone marrow, endosteum, small blood vessels, and fibroblasts are not other
sources of precursor cells
4. the periosteum is not the connective tissue membrane covering the bone - ANS-12
Which is/are true of the healing process of fractures:
1. the first change after fracture is the presence of blood cells within the tissues
adjacent to the injury site
2. within a few hours after fracture, the extravascular blood cells form a hematoma
3. all of the cells within the blood clot survive and replicate
4. within this same area, the fibroblasts degenerate and die - ANS-12
Which is/are true of the healing process of fractures:
1. days after fracture, the cells of the periosteum replicate and transform
2. the periosteal cells proximal to the fracture gap develop into osteoblasts which form
woven bone
3. the periosteal cells distal to (further from) the fracture gap develop into chondroblasts
which form hyaline cartilage
4. hyaline cartilage and woven bone unite with their counterparts from other parts of the
fracture. These processes culminate in a new mass of heterogeneous tissue which is
known as the fracture casus - ANS-14
Which is/are true of the healing process of fractures:
1. the replacement of the hyaline cartilage and woven bone with lamellar bone is known
as endochondral ossification
2. the lamellar bone begins forming soon after the collagen matrix of either tissue
becomes mineralized
, 3. the osteoblasts does not form new lamellar bone upon the recently exposed surface
of the mineralized matrix
4. new lamellar bone is not in the form of trabecular bone - ANS-12
Which is/are true of the healing process of fractures:
1. the remodelling process substitutes the trabecular bone with compact bone
2. in the remodelling process, the trabecular bone is first desorbed by osteoclasts
3. in the remodeling process, the trabecular bone is first desorbed by osteoblasts
4. the remodelling phase takes 3 to 5 months - ANS-12
Which is/are true of the ligament damage & repair:
1. rehabilitation starts in acute/inflammatory stage
2. in inflammatory stage, protection of the injured part from further damage (e.g. the use
of crutches) and rest from activity involving the injured part is recommended
3. in inflammatory stage, cryotherapy is recommended
4. in inflammatory stage, thermotherapy is recommended - ANS-23
Which is/are true of the ligament damage & repair:
1. the use of electrotherapy in repair phase encourages fibroblast activity
2. the use of electrotherapy in repair phase is not recommended
3. fibroblast cells proliferate and begin to lay down Type 3 collagen tissue, between 3-21
days after the injury
4. in the repair phase, activity involving the injured part is recommended - ANS-13
Which is/are true of the ligament damage & repair:
1. the remodelling phase can last for up to half of year
2. the remodelling phase can last for up to a year
3. risk of re-injury in the remodelling phase can be minimalized by providing additional
stability with a strapping, increasing the strength of muscles which also provide support
to the joint, and by doing proprioceptive exercises to increase the patient's sense of joint
positioning
4. risk of re-injury in the remodelling phase can be minimalized by rest from activity, ice
compression, elevation and the administration of anti-inflammatory medication - ANS-23
Which is/are true of the immobilization:
1. a muscle at complete rest loses 30% its strength each week
2. nearly half of normal strength is lost within 3 to 5 weeks of immobilization
3. the antigravity muscles are reported to experience greater loss of strength than other
skeletal muscles with inactivity
