Background The effect on joint stability of repair of type II superior labrum and biceps anchor lesions is unknown. Hypothesis Increased translations of the glenohumeral joint after a simulated type II lesion will be reduced after the lesion is repaired. Study Design Controlled laboratory study. Methods A robotic/universal force-moment testing system was used to simulate load-and-shift and apprehension tests on eight cadaveric shoulders to determine joint kinematics of the shoulder after venting, creation of a type II lesion, and repair of the lesion. Results At 30° of abduction, anterior translation of the vented joint in response to an anterior load was 18.7 ± 8.5 mm and was significantly increased to 26.2 ± 6.5 mm after simulation of a type II lesion. Repair did not restore anterior translation (23.9 ± 8.6 mm) to that of the vented joint. The inferior translation that also occurred during application of an anterior load was 3.8 ± 4.0 mm in the vented joint and increased significantly to 8.5 ± 5.4 mm with a simulated type II lesion. After repair, the inferior translation decreased significantly to 6.7 ± 5.3 mm. Conclusions Repair of a type II lesion only partially restored glenohumeral translations to that of the vented joint. Clinical Relevance Surgical techniques including improved repair of passive stabilizers injured in the type II lesion should be considered.

An improved quantitative ultrasonographic technique could assess anterior translation of the glenohumeral joint accurately and reliably

SUMMARY:Spinal curves may be produced in fetal lambs with three surgical techniques. These procedures vary from mere exposure of the costo-vertebral junction of three ribs through a paravertebral incision, to resection of the head and part of the adjacent shaft of three ribs. The fetal age varies from forty-nine to seventy-three days. The degree of curvature present at birth seems to increase in severity with decreasing fetal age at the time of surgery, but the type of surgical procedure does not appear to influence the severity of the curve, suggesting that the mechanical presence of the ribs does not prevent the development of scoliosis in these animals.Histological studies of the m. longissimus dorsi at the apices of the curves reveal two main types of abnormality in the muscle fibers. Both Type I and Type II fibers were significantly reduced in size in the biopsies taken from the side on which the surgery was performed, and there was marked alteration in the proportion of one fiber type to the other in most biopsies taken from both operated sides when compared with biopsies from unoperated twin animals.The fetal age and amount of surgical trauma appeared to play no role in the degree of muscle alteration, suggesting that even minimal surgical trauma to the paraspinal region at any fetal age between 49–73 days is sufficient to produce significant muscle fiber abnormality and spinal curvature.A parallel is drawn between these muscle findings and those in a number of human musculoskeletal diseases, and suggests the possibility of a developmental defect in the pathogenesis of these diseases.

Objective The aim of this study was to evaluate the contribution of the palmar radiocarpal ligament and the palmar ulnocarpal ligament to canine antebrachiocarpal joint stability. Materials and Methods The right carpus of four dog cadavers, free of musculoskeletal pathology, was stripped of muscle. Each specimen was placed into a custom-made joint testing machine and tested at 15° extension, and 0° and 15° flexion. A single motion tracking sensor was fixed to the metacarpal bones. All specimens were tested with all ligaments intact and after transection of the palmar radiocarpal and ulnocarpal ligaments. A range of weights between 0.2 and 2.0 kg was used to test the carpi in three directions (axial, medial/lateral and cranial/caudal) and two moments (pronation/supination and valgus/varus). Results No differences were found between the translations and rotations of the manus relative to the radius and ulna with the ligaments intact and the ligaments transected at any of the carpal angles tested, except at 15° of flexion. Increasing the angle of flexion resulted in a significant increase in cranial and caudal translation of the manus relative to the radius and ulna both in the intact and transected specimens. Clinical relevance Antebrachiocarpal joint position plays a more important role in craniocaudal antebrachiocarpal joint stability than the palmar radiocarpal and ulnocarpal ligaments.

Repair Techniques

The glenohumeral joint is the most dislocated major joint in the body with most dislocations occurring anteriorly. [1] The anterior band of the inferior glenohumeral ligament (AB-IGHL) is the primary passive restraint to dislocation and experiences the highest strains during these events. [2,3] It has been found that injuries to the capsule following dislocation include permanent deformation, which increases joint mobility and contributes to recurrent instability. [4] Many current surgical repair techniques focus on plicating redundant tissue following injury. However, these techniques are inadequate as 12–25% of patients experience pain and instability afterwards and thus may not fully address all capsular tissue pathologies resulting from dislocation. [5] Therefore, the objective of this study was to determine the effect of permanent deformation on the mechanical properties of the AB-IGHL during a tensile elongation. Improved understanding of the capsular tissue pathologies resulting from dislocation may lead to new repair techniques that better restore joint stability and improve patient outcome by placating the capsule in specific locations.
