Disc Displacement With Reduction

Objetive: This study was to compare the effectiveness of arthrocentesis versus the insertion of anterior repositioning splint (ARS) in improving the mandibular range of motion (MRM) for patients with the temporomandibular joint (TMJ) anterior disc displacement with reduction (ADDwR). Methods: 36 patients diagnosed as ADDwR were recruited and divided randomly into two groups. The first group (G1) was treated by arthrocentesis, and the second (G2) was treated using ARS. All patients were reexamined after six months. Results: Except that for protrusive movement, there were significant differences between the two groups for the percentage changes of the MRM as measured by the amount of pain free opening, unassisted opening, maximum assisted opening, right lateral and left lateral movements (p < 0.05). Conclusion: Within the context of the current study, the non-invasive, lower cost ARS, provided better results in improving the MRM when managing ADDwR cases.   Keywords Arthrocentesis; Anterior repositioning splint; TMD; Internal derangement; Anterior disc displacement; Mandibular range of motion.

A high temperature and high pressure reaction autoclave for petroleum bullets performance test is designed in this paper. Heat transfer in both vertical and horizontal reaction autoclave structure is analyzed and calculated. Considering system heat loss, heating power of these two kinds of devices is calculated in different test time. Meanwhile, temperature fields in these two kinds of autoclave are simulated. According to the comparison result, the authors come to the conclusion that temperature field in vertical reaction autoclave is uniform and can meet design demand with a temperature difference less than ±5°C. Horizontal reaction autoclave in which there are small eddies in air interlayer cannot meet demand because eddies enhance the convection heat transfer in local area. Based on this conclusion, a reasonable reaction autoclave structure can be designed.

Abstract Purpose: To evaluate the effect of the modified retrograde tendon flap technique for reconstructing the extensor tendon defect in zone Ⅱ of a finger.Methods: 12 patients with the extensor tendon defect in zone Ⅱ were investigated retrospectively. They were all treated surgically by the modified retrograde tendon flap technique, featuring the creation of a new terminal slip to bridge the extensor tendon defect using extensor tendon inner lateral bands. At the final follow-up, the range of motion at each joint of the injured finger was recorded.Results: Average follow-up was 18 months (ranging from 11 to 26 mos). Eight patients achieved full active DIPJ extension, whereas one patient had an extensor lag of 10° and three had a lag of 5°. All patients achieved normal active flexion ranges and full passive motion ranges of DIPJ compared with their uninjured side. All the involved finger joints were clinically stable, with no tenderness, pain, nail deformity, or limitation using their hands for daily life.Conclusions: The modified retrograde tendon flap technique, which is easy to operate and popularize, may be the procedure of choice in patients with a gap deficiency in Zone Ⅱ of the extensor tendon of a finger.

Abstract Background Gratifying long-term results are difficult to achieve when reconstructing osteoarthritic finger joints. Implant surgery is the most commonly used method to restore function and dexterity. However, all types of implant have disadvantages and may be a less favorable option in some cases, especially in young patients with a long expected lifetime and high demands on manual load. Implant related complications as loosening, instability, subsidence and stiffness are the main concerns. In this context, joint reconstruction using rib perichondrium might be a reasonable alternative in selected cases. The aim of the study was to evaluate the long-term results of finger joint reconstruction using rib perichondrial transplantation. Methods The study group (n = 11) consisted of eight individuals reconstructed in the proximal interphalangeal (PIP) joints and three reconstructed in the metacarpophalangeal (MCP) joints during 1974–1981. All patients were evaluated at clinical visits (median: 37 years after perichondrial transplantation, range: 34–41 years) using radiographs, disability in arm-shoulder-hand (DASH) score, Visual Analog Scale (VAS), range-of-motion (ROM) and manual strength (JAMAR). Results None of the 11 patients had undergone additional surgery. All of the PIP-joints (n = 8) were almost pain-free at activity (VAS 0,6) (range 0–4), had an average range-of-motion of 41 degrees (range 5–80) and a mean DASH-score of 8,3 (range 1–51). The mean strength was 41 kg compared to 44 kg in the contralateral hand (93%). The three MCP joints were almost pain-free at activity (VAS 0,7), (range 0–1). The ROM was on average 80 degrees (range 70–90) and the mean DASH-score was 2 (range 1–3). The mean strength was 43 kg compared to 53 kg in the contralateral hand (81%). Conclusions Perichondrium transplants restored injured PIP and MCP joints that remained essentially pain-free and mostly well-functioning without need for additional surgeries up to 41 years after the procedure. Additional studies are needed to evaluate long-term results in comparison to modern implants and to better describe the factors that determine the outcome of these procedures.

The purpose of this study was to measure the functional range of motion of the finger joints needed to perform activities of daily living. Using the Sollerman hand grip function test, 20 activities were assessed in ten volunteers. The active and passive range of motion was measured with a computerized electric goniometer. The position of each finger joint was evaluated in the pre-grasp and grasp positions. The functional range of motion was defined as the range required to perform 90% of the activities, utilizing the pre-grasp and grasp measurements. The functional range of motion was 19°–71°, 23°–87°, and 10°–64° at the metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints, respectively. This represents 48%, 59%, and 60% of the active motion of these joints, respectively. There was a significant difference in the functional range of motion between the joints of the fingers, with the ulnar digits having greater active and functional range. The functional range of motion is important for directing indications for surgery and rehabilitation, and assessing outcome of treatment.
