Laceration Wounds & Cuts

Laceration Wound

Laceration Wound

What is a Laceration Wound?

A laceration is a wound that occurs when skin, tissue, and/or muscle is torn or cut open. Lacerations may be deep or shallow, long or short, and wide or narrow. Most lacerations are the result of the skin hitting an object, or an object hitting the skin […]

Treatment Options

The past treatment of pectoralis major ruptures has been controversial. There have been studies advocating conservative treatment, some operative repair , and several have included both in their descriptions . More recently, most authors advocate early repair of these injuries . The pectoralis major functions to adduct, forward flex, and internally rotate the shoulder.

Several […]

Imaging

Imaging of the soft tissue injury in pectoralis major ruptures can be difficult. Plain x-rays can reveal bone avulsions, or loss of the pectoralis shadow. Ultrasound exam can demonstrate intra-muscular injury or loss of continuity of the tendon . CT scan can outline the muscle, but has difficulty visualizing the distal soft tissue of the […]

Clinical Evaluation

The most common mechanism for sustaining a pectoralis muscle injury is from weight-lifting or athletics. Wolfe et al.It described the transition period from eccentric loading to concentric loading (bench press position) as the most stressful to the inferior muscle fibers of the pectoralis muscle. The patient typically presents after sudden onset of pain in the […]

Anatomy

The anatomy of the pectoralis major muscle demonstrates two distinctively different parts—the clavicular head and the sternal head . We feel that when evaluating injuries to the pectoralis it is important to understand the anatomy of the pectoralis major muscle complex.

Unfortunately, many of the published reports never comment on this difference, or describe it […]

Pectoralis Major Tendon Ruptures

Key Points

The pectoralis major muscle demonstrates two distinctively different parts—the clavicular head and the sternal head. The clavicular head arises from the medial clavicle and upper sternum. It is supplied by the pectoral nerve off of the lateral cord and the deltoid branch of the thoraco-acromial artery. The sternal head arises from the sternum, […]

Early Osteoarthritis

Separate consideration should be given to the arthroscopic management of the early osteoarthritic shoulder. The disease in young patients is a challenging clinical problem. Non-surgical treatment options include physical therapy, therapeutic modalities, intra-articular corticosteroid injections, activity modification, and nonsteroidal anti-inflammatory medications .

There is a substantial amount of literature to support the use of the […]

Prosthetic Components

Obviously, the end-stage management of many of these cartilage lesions is a replacement procedure; however, in many situations the diseased portion is a limited area that is amenable to a limited replacement approach. Several devices are currently available, some experimental and some recently devised that allow for this limited resurfacing.

The currently available device is […]

Allograft Tissues

Allograft tissues have been employed to reconstruct a variety of joint surfaces, and the humerus is certainly no different. The use of smaller focal defects, however, is not extensively described in the literature with the exception of a few case series. In one study, Gerber et al.It employed a large segmental humeral head allograft to […]

Autologous Tissues

The use of autologous tissues about the knee has been commonplace for several years, and has included the transplantation of local tissue, transfer of remote tissue, and finally the genetic production of cloned tissue from knee cartilage cells .

A technique that has been used in the knee is transfer of autologous tissue from other […]
