Title: Fluid Lavage of Open Wounds (FLOW): A Multi-center, Blinded, Factorial Trial Comparing Alternative Irrigating Solutions and Pressures in Patients With Open Fractures
Brief Summary: Open fracture wounds are a constant challenge to orthopaedic surgeons, with infections a common complication. There is currently little evidence as to which is the most effective way to wash out these wounds. This study is a multi-center, prospective, randomized study. The infection rates will be compared between irrigation using high pressure versus low pressure versus gravity flow, and also saline versus a soap solution as the irrigation solution. The results from this study will help to determine the best method of washing out open fractures wounds. In this study, all open wounds will be washed out using methods commonly used by orthopaedic surgeons


Options:
A: Inclusion Criteria:

* Current episode of low back pain
* mechanical origin
* Threshold low back pain level

Exclusion Criteria:

* Contraindications to spinal manipulation or massage
* Complicating conditions that could confound clinical outcome
* Prophylactic use of prescription medication
* Health-related litigation, claims, or disability compensation
B: Inclusion Criteria:

1. Men or women who are skeletally mature.
2. Fracture of any extremity with complete radiographs.
3. Open fractures (Gustilo-Anderson Types I-IIIB) (Table 2)\*.
4. Fracture requiring operative fixation.
5. Provision of informed consent.

Exclusion Criteria:

1. Open fractures with an associated vascular deficit (Gustilo-Anderson Type IIIC).
2. Known allergy to detergents or castile soap ingredients.
3. Previous wound infection or history of osteomyelitis in the injured extremity.
4. Previous fracture with retained hardware in injured extremity that will interfere with new implant fixation.
5. Surgical delay to operative wound management greater than 24 hours from hospital admission.
6. Use of immunosuppressive medication within 6 months.
7. Immunological deficient disease conditions (e.g. HIV).
8. Fracture of the hand (metacarpals and phalanges).
9. Fracture of the toes (phalanges).
10. Likely problems, in the judgment of the investigators, with maintaining follow-up. We will, for example, exclude patients with no fixed address, those who report a plan to move out of town in the next year, or intellectually challenged patients without adequate family support.
11. Previous randomization in this study or a competing study.
C: Inclusion Criteria:

* Patients sicklisted 2-10 months for low back pain
* The following diagnosis are included: L02, L03, L84 and L86

Exclusion Criteria:

* Being off the sick list
* Pregnancy
* Osteoporosis
* Cancer
* L diagnoses suggesting recent low back pain trauma
* Specific spinal or other injuries which may account for the current back pain
* Serious psychiatric pathology
D: Inclusion Criteria:

1. Working age up to and including 59 years.
2. Sick-listed full-time for BNP for at least 42 days and at most 730 days.
3. Able to manage tolerably well to fill in forms.

Exclusion Criteria:

1. Temporary disability pension or disability pension being paid or in preparation.
2. A primary need of action by a hospital specialist.
3. Pregnancy and diseases which would probably make rehabilitation impracticable (for example, advanced pulmonary disease).
4. Whiplash-associated disorders as a primary obstacle to working.
5. Previous rehabilitation at the rehabilitation centre.
6. Other multidisciplinary rehabilitation going on or planned.
