Clinical success for both studies exceeded the study acceptance criteria of 85%. At 1-year follow-up, the flexion-extension range of motion per level: Discectomy and implantation of the device alleviates neurologic symptoms and signs similar to anterior cervical discectomy and fusion. Radiographic evidence supports maintenance of motion. The procedure is safe and the patients recover quickly. At least 5 years of follow-up will be needed to assess the long-term functionality of the prosthesis and protective influence on adjacent levels.

Patients undergoing lumbar disc herniation surgery are mostly satisfied with provided care before and after surgery, however, less satisfied with information provided. Further, patients with preoperative positive expectations on work return and realistic expectations on pain and physical recovery have a greater chance to be satisfied with the surgical results.

Neck muscle activity during loaded arm lifts 2 Practice of applications• Evaluating potential impairments in individuals with persistent disorders following cervical surgery will permit a more structured approach to rehabilitative exercise for this understudied group.• Greater muscle mechanical activity levels were observed in the ventral muscles and dorsal multifidus muscle of patients with persistent symptoms following anterior cervical decompression and fusion.• The differences may indicate an altered motor strategy in this group when performing the upper limb task.• The altered motor strategy need to be considered when prescribing exercise for their rehabilitation.Neck muscle activity during loaded arm lifts 3 ABSTRACT Objective: To compare the mechanical activity of the neck muscles during loaded arm lifting tasks in individuals with longstanding disability after anterior cervical decompression and fusion (ACDF) to that of healthy controls.Methods: Ten individuals (mean age 60 years; SD 7.1) who underwent ACDF (10-13 years previously) for cervical disc disease and 10 healthy age-and gender-matched controls participated in the study. Ultrasonography were used to investigate the degree of deformation and deformation rate of ventral and dorsal neck muscles at the C4-segmental level during a single (1 x arm flexion to 120°) and repeated (10 x arm flexion to 90°) loaded arm elevation condition. Results:The ACDF group demonstrated greater deformation and deformation rate of the longus capitis (p=0.02) as well as deformation rate of the sternocleidomastoid (p=0.04) during the 120° arm lift. For repeated 90° arm lift, there was a significant effect of group with higher deformation rate values observed in the longus capitis (p=0.005-0.01) and multifidus (p=0.03) muscles in the ACDF group. Muscle behavior did not change the repeated arm lifts (no group x time interactions) for either the ventral or dorsal muscles. Conclusions:Greater muscle mechanical activity levels were observed in the ventral muscles as well as the multifidus muscle, of patients with persistent symptoms following ACDF.These differences may be indicative of an altered motor strategy in this patient group when performing the upper limb task and may need to be considered when prescribing exercise for their rehabilitation.

The short-term results after treatment with sclerosing polidocanol injections have been shown to be good in patients with chronic painful mid-portion Achilles tendinosis. This study aimed to evaluate the longer-term effects on tendon thickness, structure and vascularity, patient satisfaction with treatment, and pain during tendon loading activity. Ultrasonography (US) + colour Doppler (CD) was used for evaluation of the tendon, and the patients graded the amount of pain during tendon loading activity on a VAS. Forty-two patient's tendons (23 men and 19 women, mean age 53 years) with a long duration (mean 32 months) of pain symptoms from mid-portion Achilles tendinosis (US + CD showed a localised thickening, structural changes and neovascularisation), were at three (mean) occasions (6-8 weeks in between) treated with US and CD guided injections of the sclerosing substance polidocanol, targeting the area with neovessels ventral to the tendon. After treatment, 37 patients were satisfied with the results of the treatment and back to previous (before injury) activity level. At the 2-year follow-up (mean 23 months), 38 patients were satisfied with the results of the treatment, and there was a significant reduction in VAS (from 75 to 7; P < 0.05). US showed a significant reduction in the mean mid-portion tendon thickness (from 10 to 8 mm, P < 0.05) and a "more normal" structure. CD showed no, or a few, remaining neovessels in the majority of the successfully treated tendons. In conclusion, treatment with sclerosing polidocanol injections in patients with chronic painful mid-portion Achilles tendinosis showed remaining good clinical results at a 2-year follow-up. Decreased tendon thickness and improved structure after treatment, might indicate a remodelling potential?
