Fractures
PTA 104 Ortho Dysfunctions

Introduction

Fracture of bone tissue significantly impacts function and participation in daily activities. Rehabilitation from fracture is a multi-disciplinary approach involving careful coordination with the health care team, patient, and involved family members. Patients often experience barriers within their home and work environments that were previously unnoticed. In this lesson, we will review the pathology and physiology of fractures, appreciate the science basis for post-operative precautions, and apply this knowledge to effective rehabilitation strategies.

Physiology of Bone

 

Science of Fracture

What is Fracture

Any break in the continuity of bone tissue (hairline or multi-fragmented (comminuted))

Why Fracture?

Stress applied to the bone tissue exceeds its strength

Stress applied to the bone tisse is rapid and multi-directional

Types of Forces

Direct: fracture occurs at point of force impact

Indirect: fracture occurs as a result of compression or rotational force applied at a distance

Healing from Fracture

Delayed Fracture Healing

Fracture Fixation

Bone can be surgically fixed internally or externally with the use of instrumentation.

Fixation devices can be described as stress shielding (no motion to fracture site - primary healing) and stress sharing (distributes forces to minimize motion - secondary healing)

Normal stresses to bone are transmitted through the devices instead of bone tissue, therefore fixation devices are often removed following fracture union to reverse device-induced osteoporosis.

Types of fixation devices are well-described in your Cameron text. Study pages 201 and 202 and check your understanding.

Safety Considerations

PTAs monitor for signs and symptoms of pre-operative and post-operative complications associated with fracture and fracture repair. Box 12.6 in your Kisner and Colby text provides an excellent summary of complications which may emerge through the healing process. Any suspected signs and symptoms of medical post-operative complications are immediately reported to the supervising PT and/or medical staff (nursing/PCP).

Deep Vein Thrombosis (DVT)

DVTs are blood clots which typically present in the lower limb.

Risk for DVT increases with recent history of cancer, paresis, immobilization/bed rest more than 3 days

Signs and symptoms of DVT include: limb redness, warmth, and swelling (increased limb girth), increased tenderness to touch, increased pain.

DVTs can mobilize (emboli) and result in a life-threatening pulmonary embolus

Exercise and soft tissue mobilization to the affected limb is contraindicated until medically cleared.

The formation and progression of a DVT into a pulmonary embolus is well-described by the National Heart Lung and Blood Institute

Pulmonary Complications

Immobilization and CNS suppresive drugs (anesthesia, pain medications, etc), can decrease the efficiency of breathing and airway clearance. Secondary complications of hospitalization due to fracture includes pneumonia and atelectasis (lung tissue collapse).

Hardware and Soft Tissue Failure

Premature weight bearing, excessive forces through healing soft tissue, and inappropriate use of orthoses can result in fracture of fixation devices and disruption of internal sutures and surgical anchors. Any sudden increases in pain or losses of function, or inability to progress to WB activities due to pain should be referred back to the supervising PT for further assessment.

Infection

Disruption of skin and bone tissue may result in local or systemic infection. Cardinal signs of inflammation, fever, shortness of breath (SOB), decreased cognition (change in arousal, A&O status) must be communicated to medical staff prior to engaging in physical activity. Vital sign monitoring before and during active-assisted and active exercises assure patient safety during activities which increase physiological stress to the cardiovascular and pulmonary systems.

 

Patient Education

Steps PTAs can take to empower the patient/family member to minimize risk for post-operative complications include:

 

Phases of Post-Operative Rehabilitation

Phases of post-operative rehabilitation are identified by the stages of healing of soft tissue and bone

  1. overlapping phases of tissue healing (acute/inflammation, subacute/proliferative, chronic remodeling)
  2. level of difficulty of activities (initial, intermediate, advanced)
  3. degree of protection of healing tissues (maximum, moderate, minimum)
  4. Roman numerals (I, II, III)

 

Degrees of Protection

Maximum Protection

Inflammatory stage/acute

Vigilant protection of tissues

May include immobilization

May include low-level stresses (e.g., partial, assisted or passive ROM)

Isometric exercise to prevent excessive atrophy

Physical agents for pain management and tissue healing

Ranges from 3-7 days to 4-6 weeks

Moderate Protection

Subacute/proliferative phase

Pain and tenderness is minimal

Increased stresses to bone and soft tissue are indicated to restore function

Exercises to restore normal kinematics, strength, function

Neuromuscular exercises to increase efficiency, coordination and control of movement

Physical agents for pain management and muscle re-education

Ranges from 4-6 weeks to 8-12 weeks

Minimal Protection/Return to Function

Begins when full to almost full, pain-free ROM is available

Joint mobility is restored and stable

Focus is on task-specific, functional activities for the individual patient and prevention of secondary complications ( e.g., fall prevention, endurance)

Ranges from 6-12 weeks to 6 months

 

 Hyperlink to Sorting Activity 

 

Role of the PTA

Etiology of fracture does not typically allow for pre-operative education and instruction by a PT or PTA. PT evaluations and treatment planning usually begin once the patient is medically stable to progressively increase activity. In order to minimize complications and promote a successful recovery, PTs and PTAs use knowledge of physiological processes to incrementally restore integrity and function of healing tissue while instructing patients in adaptive strategies for altered weight bearing. PTs establish a plan of care based on Impairments (I), Functional Limitations (FL), and Disability (D) and PTAs select interventions in the plan of care to progress patients toward short and long term goals.

The following table provides an example of treatment planning during rehabilitation from fracture based on impairments and post-operative complications:

PT/PTA Team

PTAs can be the "eyes and ears" of the PT during direct patient care, family training, and interdisciplinary care meetings. PTs rely on PTAs to gather data and make comparisons so that patients are treated within the scope of PT practice safely and effectively. In some cases, a supervising PT may not be immediately available, therefore, PTAs understand signs and symptoms which require immediate medical attention. Significant adverse findings which would require immediate communication to the supervising PT/medical staff include:

Complications specific to fracture and fracture repair include delayed or non-union of bone tissue. PTAs often see patients successively over a period of time, and can assess if patient progress is consistent with fracture healing as measured by decreased impairments and functional limitations. PTAs develop relationships and rapport with family members and caregivers and can advise the PT on discharge readiness and planning based on safety, family training outcomes, equipment needs, and home assessments.

Patient and Family Education Considerations

The level of functional limitation and disability is influenced by general health status and psychosocial factors. PTAs play an important role in integrating effective communication, respect for individual and cultural differences, and motivation techniques into the rehabilitation process. The PT/PTA team should coordinate with family, interdisciplinary staff, and community resources to promote optimal safety, health and wellness following a fracture.

Key factors which influence outcomes include

 

Child Abuse and Neglect Reporting

Fractures and Child Abuse

Fractures are the second most common injury in child physical abuse. Certain fractures are more specific indicators of abuse. Common but low specificity indicates typical presentation in childhood without consistent or significant evidence of child abuse.

High specificity

Moderate specificity

Common but low specificity

Definition of Child Abuse and Neglect in Oregon

Every state has laws in place to define and protect children from abuse and neglect. Oregon's definitions and resources can be referenced through the Department of Human Services

By Oregon law, PTAs are Mandatory Reporters of child and elder abuse and neglect. If a licensed PTA suspects abuse/neglect, there is a legal obligation to report the alleged abuse to law enforcement or the Department of Human Services.

The following statistics are from the 2009 Child Welfare Data Book published by DHS

Child protective services

67,885 reports of abuse and neglect were received.

28,584 reports were referred for investigation.

7,240 referrals were founded for abuse or neglect—involving 11,090 victims.

48.1 percent of victims were younger than 6 years old.

Threat of harm was the largest type of maltreatment incident experienced by victims (49.8 percent of incidents), followed by neglect incidents (31.1 percent of incidents).

Family services

At 42.1 percent, alcohol and drug issues represented the largest single family stress factor when child abuse/neglect was present.

The next most common stressors were domestic violence (31.7 percent) and parental involvement with law enforcement (27.0 percent).

Child Abuse/Neglect Reports and Investigations

During 2015 Oregon DHS received 69,972 reports of suspected child abuse or neglect. Of those, 32,682 reports were referred for investigation.

Of the reports referred for investigation, 6,708 were founded for abuse or neglect involving 10,402 victims; 46.6% were younger than 6 years old.

Public and private officials required by law to report suspected child abuse and neglect made 76 percent of the reports of abuse and neglect received by DHS.

Of all reports, 38.0 percent came from schools and law enforcement agencies.

10.6% of all reports of child abuse in Oregon were filed by medical personnel

There were 676 founded child abuse cases in Lane County; 606 founded cased in Jackson County, and 215 founded cases in Josephine County

Oregon Department of Human Services. 2015 Child Welfare Data Book. State of Oregon. Web 1 April 2016.

Guidelines to responding and reporting to accounts of abuse are found on the Oregon Department of Human Services website.

PTAs can access the "Report Child Abuse and Neglect" link to identify local child welfare offices by county in order to expedite the reporting process.
