Primary bone healing is the reestablishment of the cortex without the formation of a callus. It occurs if a fracture is adequately "fixed" through reduction, immobilization, and rehabilitation.

Boston Celtics forward Gordon Hayward rules out return in 2017-18

Celtics forward Gordon Hayward laid to rest any speculation he might be able to return this season, confirming via Facebook on Wednesday that he will be out until 2018-19 as he recovers from the ugly ankle fracturehe suffered on opening night.

The effect of electro-acupuncture on the healing process of a tibia fracture in a rat model

Previous studies have shown that electrical stimulation can be used to promote bone union, however the previous methods of embedding electrodes is quite invasive and risky.  More non-invasive techniques have been developed more recently (i.e. low intensity pulsed ultrasound and pulsed electromagnetic fields), however applying stimulation only to a local fracture site is challenging with these methods, and studies have shown that it is most effective when the cathode is applied directly to the fracture site.

This group from Japan suggested that the use of acupuncture needles as electrodes can eliminate the invasive procedure and allow for selective stimulation to deeper regions, making simple, quick and frequent applications possible.  They conducted a randomized control trial to examine the effect of electroacupuncture on the healing process of a tibia fracture in rats.

In this study, thirty male rats underwent unilateral osteotomies of the tibiae and then were assigned randomly to three groups of 10: 1. Electroacupuncture group (EA group) 2. Sham group 3. Control group

In the EA group, a cathodal electrode was connected to an acupuncture needle (30mm No 24, stainless steel, Seirin) percutaneously penetrating directly at the fracture site. Another acupuncture needle was inserted 15 mm proximal to the fracture site as an anode. Electroacupuncture was performed daily for 3 weeks. Using an electrical stimulator, 5ms square pulses at a frequency of 50 Hz were delivered at 20 μA for 20 minutes. In the sham group, no electrical stimulation was given to the acupuncture needle inserted at the same site as the EA group. In the control group, no treatment was given.

The response was determined at one, three, four, and six weeks after surgery by radiographic, macroscopic and mechanical examinations.

Results: The EA group showed accelerated bone healing and enhanced callus development after surgery compared to the other groups. Biomechanically, the strength of the callus in the EA group was significantly higher compared with the other groups.  There was no difference between the sham and control group in any evaluation.

Conclusion: Callus formation was promoted in the EA group over the sham and control group. The authors therefore concluded that the use of electroacupuncture can enhance callus development and bone mineralization of the bone healing process.

This study is promising and provokes discussion on the applicability of this method to human subjects.  The bones of the rats in this study were very small, so further studies would be required to evaluate how effective EA would be in bone forming for larger bones, over larger areas and in more "natural" fracture situations. In addition, the appropriate stimulation conditions need to be determined and safety parameters have to be established.
