le fratture prossimali dell'omero. complicanze neurologiche: diagnosi e trattamento
No full textPeripheral nerve damage in proximal humeral head fractures is not rare. It is more frequentin 2-part of the surgical neck, 3- and 4-part fractures and in fracture-dislocations involvingthe axillary nerve. It is possible to cause a iatrogenic nerve lesion while performing reductionand synthesis of the fracture.We have to evaluate movement and sensibility after thetrauma, before and after the treatment of the fracture.More than 90% of these peripheralnerve lesions have a spontaneous recovery. If there isn’t clinical and EMG recovery after 4-6months, there is the indication to surgical revision and reconstruction by 2 or 3 autologoussural grafts, with a percentage of good results of 74% (deltoid in M4- M5)

lesioni associate nervo ascellare-cuffia-instabilità (terribile triade)
No full textla lussazione della spalla può provocare una lesione del nervo ascellare e rottura della cuffia determinando la cosiddetta terribile triade. tale lesione è di diagnosi difficile, spesso misconosciuta inoltre è difficile decidere il trattamento più corretto. il lavoro tratta 24 pazienti con un eccellente-buono risultato nel 33% e nel 41,7% discreto.nella tempistica del trattamento è importante ricostruire precocemente la cuffia e valutare l'evoluzione della lesione nervosa, che se non recupera va ricostruita a 5-6 mesi dal trauma
Striated muscle fiber apoptosis after experimental tendon lesion in a rat model
No full textTendon lesions induce muscular atrophy, the nature of which has not yet been clearly related to lesion etiology
and entity. In the present study, tendon and muscle alterations were assessed after experimental tendon lesion
of the Infraspinatus muscle in young rats. The consequences of lesions differed on the basis of both extension
and injured tissue vascularization, that is apoptosis and/or degeneration, differing mainly by energy demands:
apoptosis requires high energy levels (proportional to vascular supply), but degeneration does not. It is well
known that tendons are poorly supplied with blood compared with muscular masses, which are abundantly
vascularized. Five weeks after tendon surgical section, tendon/muscle samples were taken for TUNEL and
transmission electron microscopy. The structural results reported here identified different tendon/muscle
alterations: degeneration of tendon without signs of apoptosis, and atrophy of muscle fibers due only to
apoptosis. This led to the formulation of the following hypothetical sequence of events: a tendon lesion, not
recovering quickly due to the poor tendon blood supply, results in degeneration of the injured tendon, which,
in turn, induces a partial disuse of the muscle mass, which consequently atrophies (proportionally to the
severity of tendon lesion) by striated muscular fiber apoptosis. The authors suggest that the different behavior
of the two tissues depends on the marked difference in their vascularization

No full textPurpose of this study is to evaluate the effectiveness of muscle transfer of the teres major in the treatment of irreparable posterosuperior injuries of the rotator cuff. Long-term monitoring of the results obtained in 20 patients treated at our clinic using this method are reported, comparing the data obtained in evaluations of results with preoperative values. Clinical evaluations were obtained using the Constant Score System, while X-ray examination showed the presence of osteoarticular modifications, and MRI and electromyography the preserved morphology and function of transplant. The mean Constant Score increased from 31.6 points preoperatively to 66.1 points postoperatively at the time of follow-up. At follow-up, MRI allowed us to evaluate any fatty degeneration of the muscle fibers of transfer and the integrity of tendinous insertion on the humeral greater tuberosity. The obtained results allowed us to reveal the advantages and the disadvantages of teres major transplant in irreparable posterosuperior ruptures of the cuf
