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.

To improve the test speed and efficiency, a virtual automatic test system of missile autopilot is designed. The inbuilt computer is used as the core of the system; the modularization instrument bus standard which composed of the PXI card, the programmable instrument and other advanced test techniques is adopted. The automation test device hardware facility is used in the virtual automatic test system; the pilot mechanism fault analysis software is developed, so the faults of the missile autopilot can be located faster and more accurate. The virtual automatic test system can be used to test the current parameters, special capability and the function of the electronic parts among the missile weapon system.

The Impact

Background/Aim. Hand impairment in systemic sclerosis (SSc) patients is the most frequent manifestation of this progressive disease and often cause problems in daily activities and working ability. The correlation of altered hand functions in patients with SSc and their impact on working ability is not fully explained. The objective of this study is to assess the impact of altered hand functions of patients with SSc on their working ability. Methods. We assessed 20 patients with SSc (17 females, 3 males), with mean age of 45.5 ? 11.9 years (min 29, max 69, Med 44.0 years). The movements of fingers, wrist and forearm were examined by measuring active range of motion of the hand and fingers, muscle strength of the fingers, the skin lesions by modified Rodnan score, the function of the fingers, hands and forearms by the Hand Mobility in Scleroderma (HAMIS) test, as well as the condition of the capillaries in the fingers by capillaroscopy and working capacity by Work Ability Index (WAI). Results. Reduced strength on at least one tested muscle, was established in all patients, thickening of the skin on the hands in 14/20 (70%) and the fingers in 19/20 (95%), ?scleroderma type? capillary changes in 15/17 (85%), decreased range of motion in finger joints in 16/20 (80%) of the patients. Also, 14/20 (70%) of subjects reported problems at work [decrease performance achieved in 8/20 (40%), reduction of working hours in also 8/20 (40%), leaving out some of the work in 14/20 (70%), and investing of extra effort in 15/20 (75%)]. By means of WAI, work ability assessment questionnaire, it was found that the working capacity was reduced in 11/20 (55%) of our patients. None of the patients was in the group of the most serious cases, the ?poor? category; in the ?moderate? category there were 6/20 (30%), while 5/20 (25%) of the patients were in the group with minimally reduced working capacity (?good? category). There was a statistically significant correlation between the thickened skin on the fingers (p < 0.05), reduced muscle strength in the fingers (p < 0.002) and limited mobility of the individual finger joints (p < 0.05), with information on reduced working capacity obtained by means of WAI questionnaire and with answers to questions about problems at work. Conclusion. The thickened skin on the fingers, reduced fingers muscle strength and limited mobility of certain finger joints in patients with SSc cause decreasing working capacity for all jobs that include manual activities.
