A comparison of the healing properties of rabbit Achilles tendon injuries at different levels.

Rabbit Achilles tendons were transsected at the muscle-tendon junction (Group 1), midtendon (Group 2), or at the calcaneus insertion (Group 3). Treatment consisted of immobilization in a long leg cast without surgical repair. The contralateral leg served as a control. Tensile testing was performed at four weeks. Groups 1 and 2 failed most often in the proximal muscle rather than at the healing site. In contrast, Group 3 failed more often at the healing site than in the muscle and was statistically superior to Groups 1 and 2 with respect to strength and stiffness. Statistically, control specimens showed failure at the musculotendinous junction at greater loads and were stiff compared to the experimental groups.

The role of ultrasound in the management of zone 1 flexor tendon injuries.

We have reviewed 22 flexor tendon repairs in zone 1 undertaken in Hobart, Tasmania, during the period 1986 to 1991. The repairs were assessed using both ultrasound and Strickland's clinical criteria. The results are presented, and the two methods of assessment compared. A new method of grading results is proposed based on the ultrasound findings. We have demonstrated that ultrasound has an important role to play in assessing tendon repairs, both in the on-going management and as an objective method of measuring the results of repair.

[Management of Achilles tendon injuries in our department].

Authors introduce the different methods in the treatment of Achilles tendon injury, including the "ordinary" surgical technique and the new method, using Tissucol. They point out the importance of indication and proper rehabilitation. Concerning the results and the complications they give evaluation of 98 patients.

[The results of nerve repair in combined nerve-tendon injuries of the forearm].

BACKGROUND: We evaluated the clinical and functional results of nerve repair in patients with combined tendon-nerve injuries of the forearm. METHODS: The study included 68 patients (58 males, 10 females; mean age 33.5 years; range 5 to 48 years) with combined tendon-nerve injuries of the forearm. A total of 96 nerves were repaired. Patients with nerve defects were excluded. Both median and ulnar nerves were injured in 17 patients; median and ulnar nerve injuries were detected in 17 patients and 34 patients, respectively. The mean time to operation was four hours (range 20 min to 24 h). Primary nerve repair was performed in 60 patients, and secondary repair was performed in eight patients. The interfascicular technique was employed in 18 patients, and epiperineural suture in 50 patients. Rehabilitation included early motion using the Washington regimen. A modified MRC (Medical Research Council) motor and sensory classification system was used for postoperative evaluation. The mean follow-up was at least two years. RESULTS: The modified MRC results were as follows: of 17 patients with median nerve injuries, 10 had excellent, seven had good results. Of 34 patients with ulnar nerve injuries, the results were excellent in nine, very good in 10, good in 10, and fair in five patients. Of those with median and ulnar nerve injuries, four, seven, and six patients had excellent, very good, and good results, respectively. Overall, 61 patients (89.7%) had satisfactory results. A significant correlation was found between age and the MRC results (p=0.016). CONCLUSION: Primary nerve repair followed by early motion results in substantial rates of excellent and satisfactory results in patients with combined nerve-tendon injuries.

An experimental study on the application of extracorporeal shock waves in the treatment of tendon injuries: preliminary report.

The use of low-energy extracorporeal shock wave therapy (ESWT) has recently been introduced in pseudoarthrosis, fracture, and wound healing for both clinical and experimental purposes. In this study, we created an experimental rat model to investigate the histopathological and biochemical effects of ESWT in the healing of tendon injury that may accompany fractures. Twenty-eight rats were used for the histopathological investigation. The right achilles tendon of the rat was cut and then sutured, using Modified Kessler stitches method. Five hundred shock waves, set at 14 kV, were applied to the achilles tendon under fluoroscopic guidance. Fourteen rats that underwent a sham operation served as the control group. Biochemical studies were done on 20 rats, divided into four groups of 5 rats in each. The first and second groups received 500 shock waves, at 14 kV, after the cutting and repairing of the Achilles tendon. To measure hydroxyproline levels, the rats in the first and second groups were killed on postoperative days 3 and 9, respectively. The third and fourth groups served as controls. Hydroxyproline levels were found to be high in the study groups. The histopathological findings and the increased hydroxyproline levels revealed that ESWT may facilitate tendon healing after trauma.

Ultrasonographic and histopathological findings in equine superficial digital flexor tendon injury.

The ultrasonographic and histopathological findings in 12 normal and 28 injured superficial digital flexor tendons, with lesions ranging in duration from 2 days to 15 months, were compared. A consistent relationship between the ultrasonographic and histological findings was demonstrated. The echogenicity of lesions, the distinctness of their delineation from the surrounding tissue, and the presence and arrangement of the linear echoes were useful features by which to assess the ultrasonograms. Acute lesions were anechoic, a complex mixture of anechoic and hypoechoic areas, or diffusely hypoechoic. These appearances represented haemorrhage, fibrolysis and early granulation tissue. Fibroplasia and granulation tissue produced well to moderately well defined hypoechoic lesions. Chronic fibrosis was characterised by heterogeneously echogenic areas which were poorly defined from the surrounding tissue and had irregularly-arranged linear echoes on longitudinal images. Intratendinous scar formation resulted in multiple hyperechoic foci. Extensive peritendinous lesions were readily apparent on ultrasonograms, but intertendinous adhesions were more difficult to assess, and produced ill-definition of the borders between the superficial and deep digital flexor tendons.

MR imaging of tendon injuries about the foot and ankle.

This article reviews the common abnormalities of the major tendons about the foot and ankle and their etiologies. The abnormalities include peritendinitis, tendinosis, and tendon rupture. The role of MRI in diagnosis and the imaging features in these abnormalities are discussed.
