Analysis of the effects of deep mechanical massage in the porcine model.
Deep mechanical massage has been advocated as an alternative or adjunctive therapy for the contouring of subcutaneous fat and as a treatment for cellulite. We evaluated the effects of deep mechanical massage using two pig models. Yucatan pigs were divided into three groups (n = 4). ⋯ Analysis showed a significant reduction of measured forces at the midflank after the treatments. The actual force measured with each particular maneuver varied between different operators but not with different suction settings, suggesting that the technique of administering the treatments is the primary factor in creating the force within the tissue. This leads to the conclusion that deep mechanical massage is highly dependent on the individual operator of the device.

Immediate closure of abdominal incisions after exploration and treatment of gunshot wounds is not always feasible or advisable. Significant bowel edema after massive fluid resuscitation might preclude primary closure, whereas any attempt to close under tension might result in complications ranging from wound dehiscence, infection, and necrosis to the abdominal compartment syndrome with abdominal, cardiopulmonary, and renal complications. For these difficult cases, the open technique has been recommended. ⋯ With this treatment protocol, patients can recover faster from their trauma surgery and the risk of perioperative complications can be reduced. After final reconstruction, the continuity, stability, and strength of the abdominal wall are maintained in the vast majority of cases with the use of autogenous tissue and without the need for alloplastic material. With close cooperation between the trauma team and the plastic surgeon and appropriate timing and planning of each stage, the success rate of the technique is high and the incidence of complications limited.

Comparative StudyComparison of carpal canal pressure in paraplegic and nonparaplegic subjects: clinical implications.
The purpose of this study was to evaluate the pressure within the carpal tunnel that was generated with certain tasks in paraplegic versus nonparaplegic subjects. Four groups of subjects were evaluated: 10 wrists in six paraplegic subjects with carpal tunnel syndrome, 11 wrists in six paraplegics without the syndrome, 12 wrists in nine nonparaplegics with the syndrome, and 17 wrists in 11 nonparaplegics without the syndrome. Carpal canal pressures were measured in the wrists in three positions (neutral, 45-degree flexion, 45-degree extension) and during two dynamic tasks [wheelchair propulsion and RAISE (relief of anatomic ischial skin embarrassment) maneuver]. ⋯ Within each group of subjects, wrist extension and wrist flexion produced a statistically significant increase in carpal canal pressure (p < 0.05), compared with the neutral wrist position. Dynamic tasks (wheelchair propulsion and the RAISE maneuver) significantly elevated the carpal canal pressure in paraplegics with carpal tunnel syndrome, compared with the other groups (p < 0.05). Lastly, there is a linear positive correlation between carpal canal pressure and external force resistance.

The distally pedicled peroneus brevis muscle flap: a new flap for the lower leg.
Defects of the skin and soft tissue in the region of the lateral malleolus of the ankle and the Achilles tendon, resulting in exposed bone, tendons, or osteosynthetic material, cannot be covered with free skin transplants. Local or free flaps must be employed. The authors present the construction of a peroneus brevis muscle flap with a distal pedicle as a useful alternative. ⋯ The distally pedicled peroneus brevis muscle flap is a reliable means for covering defects in the lower leg. This form of muscle flap has not yet been described in the known literature. In the authors' opinion, this flap constitutes a logical and valuable extension of local flap procedures for plastic surgery in the distal leg region.
