ABSTRACT
Fifty total hip arthroplasty (THA) patients and 24 total knee arthroplasty (TKA) patients were randomized in a controlled study to examine the effects of cold therapy (via thermal blankets) in the postoperative period. The postoperative hospital stay was significantly shorter for the cold-therapy (50 degrees F) compared with control (70 degrees F) groups (by 1.4 days, P = 0.03) for THA patients. There was a similar but nonsignificant trend observed in the TKA groups (1.5 days shorter, P = 0.19). Total knee arthroplasty patients using cold therapy achieved independent ambulation an average of 1 day sooner than TKA control patients, but this difference did not reach statistical significance (P = 0.08). There were no statistically significant differences between the control groups or the test groups for both THA and TKA patients in narcotic usage, postoperative range-of-motion (ROM), or rate of progression of ROM.

A number of techniques for achieving small joint arthrodesis in the hand combine various forms of internal fixation with external cast or splint immobilization. Rates of arthrodesis in most cases are quite high. However, the prolonged period of adjacent joint immobilization from casting can extend rehabilitation time and limit hand function during healing. Compression arthrodesis has been used effectively in a number of larger joints, such as the knee and ankle. Miniaturization of existing external fixation compression devices now enables the application of this principle to the small joints of the hand. A series of 20 metacarpophalangeal and interphalangeal joints underwent arthrodesis in which a miniature external fixation/compression frame was used. Nineteen of 20 joints demonstrated complete primary arthrodesis within 6 weeks; one fibrous union developed in a distal interphalangeal joint and no postoperative deformities occurred. Complete stabilization was provided by the fixator, thus allowing immediate postoperative adjacent joint function.
