|Lower Extremity Periarticular Fractures|
|Study Design:||Observational Model: Case Control
Time Perspective: Prospective
|Official Title:||Early Standardized Weight Bearing Utilizing Immersion Therapy Following Periarticular Lower Extremity Fractures: Clinical and Radiographic Outcomes|
- Immersion Therapy [ Time Frame: 10 weeks ]
- Standard ROM while in the hospital
- two weeks of immersion therapy, patients perform their physical therapy immersed in the pool to their neck (5-10% total body weight).
- weeks 6-8, patients are immersed to their mid-chest (nipple level- 15-30% total body weight).
- weeks 8-10, patients are progressed to physical therapy while immersed only to their waist (navel level- 50-60% total body weight).
- ten weeks, patients are allowed to weight bear as tolerated and begin formal dry land ambulation training under the supervision of a licensed physical therapist .
- Traditional non-weightbearing [ Time Frame: 10 weeks ]
- ROM therapy initiated in the hospital.
- Passive Motion therapy for 4 weeks.
- Formal physical therapy continued as needed
- Short Musculoskeletal Function Assessment [ Time Frame: 1 year ]
- Time to return to work. Assessed at each clinical visit, and by mailings if necessary.
- Standard radiographs will be obtained from the study patients per usual at post-operative visits. Any loss of fixation will be assessed. No additional radiographs will be obtained outside of the current standard of care.
- Adverse events will be tabulated.
- The short Musculoskeletal Function Assessment (SMFA) will be administered at patient's 3 month, 6 month and 1 year follow-up clinic appointments and/or by mail, as necessary.

Immersion Therapy- Study
1. Patients who participate in the immersion therapy post-operative protocol and begin progressive weight bearing at 4 weeks (study)
2. Patients who undergo the traditional 10-week non-weight bearing post-operative care protocol (control)
Fractures of the lower extremity are common injuries that can lead to temporary or permanent disability.13 Fracture healing, regardless of treatment, is a multifactorial process that is influenced by time, biomechanics, and host biology (among other variables). The degree, timing, progression, and type of weight bearing after fractures involving the pelvis and lower extremities is an area of debate in the clinical management of a broad spectrum of orthopedic injuries.1,2,4-9,11,15 Periarticular fractures of weight bearing joints are an area of particular interest with regard to post-operative weight bearing due to the prolonged periods that patients must be non-weight bearing after surgery.
Some degree of impairment is inevitable with any traumatic injury. The majority of authors writing about post-fracture weight bearing have determined that timing and extent of weight bearing has an effect on fracture healing, while a small number of authors have published results demonstrating the opposite.14,16,19,21 In addition to potential impacts on healing rates, limited or non-weight bearing carries the added insult of loss of bone density and muscle mass.3,10,12,17,20,22
Traditionally, patients with periarticular fractures have been required to be non-weight bearing on their effected extremity for up to 12 weeks. At this institution, most patients have been required to remain non-weight bearing for 10 weeks, followed by progressively increased levels of weight bearing according to patient tolerance. One of the orthopaedic traumatologists at this institution uses immersion therapy to allow patients with periarticular fractures to begin weight bearing prior to the ten-week mark.
Immersion therapy requires that patients perform their physical therapy, with a trained therapist, in a swimming pool. The use of the pool in post-fracture care may be able to provide a structured and standardized partial weight-bearing environment that could allow for early mobilization. It also has the potential to improve clinical outcomes by mitigating at least some of the loss in bone and muscle mass during the post-operative period; thereby, potentially speeding functional recovery. Immersion therapy is currently utilized on-site at the University of Utah Orthopedic Center for a variety of diagnoses, including in post-fracture care.
There is essentially no orthopedic literature regarding immersion therapy in the management of post-fracture rehabilitation with regard to early weight bearing. Specifically, the investigators are aware of no clinical outcome studies that investigate standardized early weight bearing protocols following periarticular fractures of the lower extremity.
