Does Improvement towards a Normal Cervical Sagittal Configuration Aid in the Management of Lumbosacral Radiculopathy: A Randomized Controlled Trial

The Subjective and Objective Improvement Using Chiropractic Biophysics® Protocols

The aim of this study is to describe the Chiropractic BioPhysics® (CBP®) (Chiropractic BioPhysics, Eagle, USA) technique in alleviating the persistent spine pain syndrome (PSPS) and dysfunction in a 50-year-old female who suffered for many years. The purpose of this study is to provide clinicians with a potential treatment option for failed back surgery syndrome (FBSS) and PSPS that doesn't respond to other treatments. The patient did not receive benefits from pharmaceutical and conservative therapies following a low back lifting injury in 2004. After several years of suffering from widespread spinal pain and dysfunction, she received a lumbosacral pedicle screw surgical fixation. The initial surgery was unsuccessful and a follow-up revision and expansion of the fusion failed to alleviate the pain and dysfunction as well. After treatment using CBP, the patient received subjective, objective, and radiographic improvements with long-term stability measured at follow-up. Given that spine pain and low back pain are the number one cause of disability in the world, having economical, repeatable, and measurable techniques to improve even difficult cases is important for astute clinicians treating spine pain.

A Comparison of Two Forward Head Posture Corrective Approaches in Elderly with Chronic Non-Specific Neck Pain: A Randomized Controlled Study

Forward head posture (FHP) is a common postural displacement that is significantly associated with neck pain, with higher risks of having neck pain in female and older populations. This study investigated the effect of two different forward head posture (FHP) interventions in elderly participants with poor posture and non-specific neck pain. Sixty-six elderly participants with a craniovertebral angle (CVA) < 50° were randomized into either a Chiropractic Biophyics® (CBP®) or a standardized exercise based FHP correction group (Standard Group). Both groups were treated for 18 sessions over a 6-week period. A 3-month post-treatment follow-up was also assessed with no further interventions. The CBP group received a mirror image® exercise and a Denneroll™ cervical traction orthotic (DCTO); the standard group performed a protocol of commonly used stretching and strengthening exercises for the neck. Both groups received 30 min of their respective interventions per session. The primary outcome was the CVA, with secondary outcomes including pain intensity, Berg balance score (BBS), head repositioning accuracy (HRA), and cervical range of motion (CROM). After 18 sessions (6 weeks later), the CBP group had statistically significant improvement in the CVA (p < 0.001), whereas the standard group did not. In contrast, both groups showed improved functional measurements on the BBS and HRA as well as improved pain intensity. However, at the 3-month follow-up (with no further treatment), there were statistically significant differences favoring the CBP group for all outcomes (p < 0.001). The differences in the between group outcomes at the 3-month follow-up indicated that the improved outcomes were maintained in the CBP group, while the standard group experienced regression of the initially improved outcomes at 6 weeks. It is suggested that the improvement in the postural CVA (in the CBP group but not in the standard group) is the driver of superior and maintained pain and functional outcomes.

The Biomechanical Burden of Orthopaedic Procedures and Musculoskeletal Injuries Sustained by Orthopaedic Surgeons: A Systematic Review

BACKGROUND

Orthopaedic surgeons are at high risk for experiencing work-related musculoskeletal (MSK) injuries and chronic pain due to repetitive large magnitude forces, altered posture from lead vests, and prolonged irregular body positions. We sought to synthesize available evidence regarding (1) the biomechanics of orthopaedic surgery and (2) MSK injuries sustained by orthopaedic surgeons with subsequent treatment and consequences.

METHODS

To conduct this systematic review, we queried 4 databases (PubMed, Embase, MEDLINE, and Web of Science) for original research studies presenting on the biomechanics of orthopaedic surgery or MSK injuries sustained by orthopaedic surgeons. Studies were excluded if they were not original research (i.e., reviews) or reported on non-MSK injuries and injuries in patients or nonorthopaedic specialists. The literature search yielded 3,202 publications, 34 of which were included in the final analysis.

RESULTS

Eight studies reported on the biomechanics of orthopaedic surgery. Surgeons spent an average 41.6% of operating time slouched. Head and whole spine angles were closest to natural standing position when using a microscope for visualization and with higher surgical field heights. Use of lead aprons resulted in a shifted weight distribution on the forefoot, gain in thoracic kyphosis, and increase in lateral deviation from postural loading. Twenty-six studies reported on MSK symptoms and injuries experienced by orthopaedic surgeons, with an overall prevalence from 44% to 97%. The most common body regions involved were lower back (15.2%-89.5%), hip/thigh (5.0%-86.6%), neck (2.4%-74%), hand/wrist (10.5%-54%), shoulder (7.1%-48.5%), elbow (3.1%-28.3%), knee/lower leg (7.9%-27.4%), and foot/ankle (7%-25.7%). Of surgeons with any reported MSK symptom or injury, 27% to 65.7% required nonoperative treatment, 3.2% to 34.3% surgery, and 4.5% to 31% time off work. Up to 59.3% of surgeons reported that their injuries would negatively influence their ability to perform surgical procedures in the future.

CONCLUSIONS

The orthopaedic surgeon population experiences a high prevalence of MSK symptoms and injuries, likely secondary to the biomechanical burdens of tasks required of them during strenuous operations.
