Allograft Bone Patellar Bone Reconstruction

– Discussion:     – general discussion of allograft tissue:     – as pointed out by Harner et al. (1996), subjective knee scores were slightly better for knees having ACL – bone patellar bone allograft (as compared to BPB autograft patients)            – objective ratings included normal (or nearly normal) … Read more

Allografts

– see bone graft menu – Discussion of Allografts:     – see autograft menu and bone healing:      – allografts are most indicated when bone grafting is required along with need for mechanical structural support;     – morselized bone graft:     – structural bone grafts:      – fresh allografts            – generally … Read more

Adult Lateral Condyle Fracture

– See: – Pediatric Lateral Condyle Frx – Discussion:     – frxs of lateral condyle that involve capitulum alone or extend medially to involve the lateral portion of trochlea;     – see capitellum fracture – Lateral approach      – typically the plate is positioned posteriorly, and can be placed if needed as far as … Read more

Adult Humeral Inter-condylar Fractures

 – Fractures Subtypes:     – capitellar and coronal shear frx     – distal humeral frx      – lateral condyle frx      – medial condyle frx      – Muller’s Classfication:            – type A: extra-articular fracture;             – type B: uni-condylar fracture;            – type C: bi-condylar fracture;  … Read more

Adult Humeral Inter-condylar Fractures: Restoration of Frx Anatomy

– Technique:      – it is helpful to have the patient paralyzed during the reduction (requires general anesthesia);      – anatomic reduction of the condyles is performed first;      – remember that the  common factor in fixation failure in these fractures is comminution and/or osteoporosis;      – best-fit method:             … Read more

Adolescent Blounts Disease

– Discussion:   – adolescent tibia vara (Blount’s disease), results from disordered growth of  proximal medial physis & metaphysis;   – localized varus deformity, often accompanied by medial tibial torsion;   – caused by osteochondrosis resulting from mechanical stress converting physiologic bowlegs to tibia vara;   – risk factors: common in blacks & obese children; … Read more

Adductor Magnus

– origin:       – posterior fibers: ischial tuberosity;       – anterior fibers: ramus of ischium and pubis; – insertion:       – from a line extending from the greater trochanter along linea aspera, medial suprcondylar line and adductor tubercle on medial condyle of femur; – action:         – … Read more
