Flexible arm splints in the control of a Lesch-Nyhan victim's finger biting and a profoundly retarded client's finger sucking.

Flexible arm splints permit the control of hand-to-mouth contacts without restricting range of motion. In the present study they effectively suppressed the self-injurious finger biting of a child with Lesch-Nyhan disease and a profoundly retarded client's stereotypic finger sucking. They appear to offer an easily applied and much less restrictive alternative to the soft-tie and tubular arm restraints in common use.

Work-related eye injuries among union carpenters.

Union administrative records were combined with workers' compensation data to identify a cohort of 12,958 active union carpenters, their person-time at risk, and their documented work-related eye injuries between 1989 and 1995 in the state of Washington. The injuries were described using ANSI codes for injury nature, type (mechanism), and source or object associated with the event. Injuries which resulted in paid lost time from work were also described based on the ICD-9 codes attached to claims for their medical treatment. Overall rates of filing compensation claims for eye injuries as well as age, gender, and union local specific rates were calculated. To identify high risk subgroups and explore incident and recurrent events, the person-time and events were stratified by age, gender, time in the union, claim status, and predominant type of work of the union local with which each carpenter was affiliated for multivariate analyses with Poisson regression. Eye injuries were responsible for 12 percent (n = 1730) of workers' compensation claims during this time period, exceeded only by back and finger injuries. Thirty-one claims resulted in paid lost time from work and these cases accounted for one-third of all costs for medical care for eye injuries. At least 10 percent of all medical costs for eye injuries and 35.5 percent of medical costs for eye injuries which resulted in paid lost time were associated with injuries sustained while hammering--a very common carpenter exposure. Claims were filed at an estimated rate of 6.1 per 200,000 hours worked. Individuals with previous compensation claims for eye injuries had rates of injury 1.6 times higher than individuals without previous eye injuries. Rates decreased significantly with age and time in the union. Eye injuries among these union carpenters were very common, but the rate of injuries severe enough to require paid time off work was quite low. These findings raise questions about factors which might influence the failure to use appropriate protection including availability and acceptability of eye protection, use by peers, and perception of risk.

[Clinical investigation of the combined therapy on deformed fingers after burn injury].

OBJECTIVE: To investigate the benefit of the combined therapy for deformed fingers after burn injury by comparing with the conventional one, and to sum up some experience. METHODS: From June 1999 to June 2004, 56 patients with deformed fingers entered the trial. In 28 patients of treatment group who received combined therapy (operation with post operational systematic convalescent care, group A), there were 20 males and 8 females (14-47 years), 129 fingers of 47 hands were involved. In 28 of conventional group who received conventional therapy (the same operational principle, and self-convalescent-care with out-patient service guidance, group B), there were 17 males and 11 females (18-51 years), 107 fingers of 42 hands were involved. Before and after the therapy, the finger's motor function were assessed according to the Swanson method. The hand's motor function was assessed through the Nine Hole Peg Test. RESULTS: The follow-up was 12-19 months in group A and 13-20 months in group B. The index of ankylosis (IA) of group A before therapy was 82% +/- 20%, and 45% +/- 13% after therapy; while the IA of group B before therapy was 78% +/- 17%, and 52% +/- 14% after therapy. The decreased of IA between before therapy and after therapy was 37% +/- 15% in group A, and 26% +/- 15% in group B, showing significant difference between the two groups (P<0.05). The Nine Hole Peg Test value of group A was 28.34 +/- 5.62 s before therapy, and 20.73 +/- 4.25 s after therapy; while that of group B was 27.47 +/- 5.78 s before therapy, and 21.86 +/- 4.12 s after therapy. The decrease of the Nine Hole Peg Test value between before therapy and after therapy was 7.61 +/- 2.27 s in group A, and 5.61 +/- 2.94 s in group B, showing statistically significant difference (P<0.05). CONCLUSION: The combined therapy is more effective than the conventional one.

Sports injuries in adolescents' ball games: soccer, handball and basketball.

In a prospective study of 302 adolescent players in three ball games (soccer, handball and basketball), 119 incurred injuries. The injury incidence (number of injuries per 1000 playing hours) was 5.6 in soccer, 4.1 in handball and 3.0 in basketball. Ankle sprains accounted for 25 per cent of the injuries, finger sprains 32 per cent, strains in the thigh and leg 10 per cent, and tendinitis/apophysitis 12 per cent. The most serious injuries were four fractures, one anterior cruciate ligament rupture, and two meniscus lesions. The most serious injuries, with the longest rehabilitation period, occurred in soccer. In soccer, many injuries occurred during tackling and contact with an opposing player, while the injuries in handball and basketball were often caused by ball contact and running.

Free and island flap transfer for soft tissue defects in the hand and forearm.

Two hundred twenty patients with soft tissue defects in the hand and forearm were treated with 226 free and island flap transfers. Reconstructed sites involved the thumb in 74 cases, the fingers in 117, the hand in 30, and the forearm in 5. Seventy-nine patients received 82 free flaps, and 141 patients received 144 island flaps. Fifty-six finger reconstruction cases and 73 of 74 thumb reconstruction cases had sensory flap transfers. In the free flap transfer group, 77 flaps survived (93.9%), and 5 failed. In the island flap transfer group, 140 flaps survived (97.2%), and 4 failed. Of the five-failures in the free flap transfers, four were dorsalis pedis flaps, two of which were on patients with an arteriovenous fistula. Of the four failures in the island flap transfers, two were posterior interosseous flaps and two were digital island flaps. All four were reverse-flow island flaps.

[High resolution ultrasound diagnosis of the annular tendon system of the hand].

High-resolution ultrasonography has gained wide acceptance in the evaluation of tendons and tendon sheaths of the finger flexors. The annular pulleys are depicted as a hypoechoic band surrounding the flexor tendons. In patients with trigger finger or polyarthritis, the tendons as well as the pulleys are of interest to the investigator. Ultrasonography allows direct or indirect diagnosis of partial and total disruptions of the pulleys. Loss of (parts of) the pulleys can be seen as a direct sign and bowstringing of the tendons during forced flexion as an indirect sign. We provide a review of the literature regarding this topic and present our experiences with better visualization employing the latest ultrasonographic equipment (such as Sono-CT).

Microvascular second toe transfer for digital reconstruction.

Reconstruction of a severely damaged hand, with multiple amputations of digits, presents a difficult reconstructive problem. The development of a safe method of transfer of the great toe for thumb reconstruction, using the dorsalis pedis artery and the saphenous vein, suggested the possibility of one-stage microvascular transfer of the second toe for reconstruction of fingers. In two patients a one-stage transfer of the second toe was done to replace an index finger and in another for restoration of part of the left ring finger. The transplants survived without anticoagulants and vessel complications were not encountered. Sensory return was adequate and a significant improvement in function was achieved.

Vascular basis of dorsal digital and metacarpal skin flaps.

We studied the vascular anatomy of dorsal digital skin flaps and the vascular anastomoses between the dorsal cutaneous branch of the palmar digital artery (PDA) and the dorsal digital branches (the terminal branches) of the dorsal metacarpal artery (DMA) at the level of the proximal phalanx. Eight fresh cadavers (16 hands) were injected with a lead oxide-gelatin mixture. Our radiographic assessment revealed that there were 2 sources of the arterial supply to the dorsum of the digit, the dorsal digital branches of the DMA, and the dorsal cutaneous branches of the PDA. These branches anastomose with each other. A flap including the territory of the dorsal cutaneous branches of the PDA and a part of the territory of the DMA can be harvested on the dorsal aspect of the proximal and middle phalanges. The extended neurovascular island flap, based on the PDA and the dorsal branch of digital nerve, can be transposed to the volar surface of an adjacent finger resurfacing the entire length of the digit.

Free flap from the flexor aspect of the wrist for resurfacing defects of the hand and fingers.

The distal portion of the flexor aspect of the forearm has been used as the donor site of full-thickness skin grafts, venous skin grafts, and Chinese forearm flaps. This article describes the use of a free flap harvested from the flexor aspect of the wrist and based on the superficial palmar branch of the radial artery to repair skin defects of the hand and fingers. The advantages of this flap are as follows: (1) the operative field is the same; (2) the radial artery is preserved; (3) it is thin, pliable, and hairless and thus can supply a gliding surface for tendons beneath it; (4) when it involves a palmaris longus tendon and/or the palmar cutaneous branch of the median nerve, it can be used as a vascularized tendon or nerve graft; and (5) in view of the flow-through type of the pedicle of the flap, the digital artery can be reconstructed simultaneously. However, it should be noted that a hypesthesia in the proximal central carpal area remains when the palmar cutaneous branch of the median nerve is harvested as a vascularized nerve graft. The scar of the donor site should be left in the distal wrist crease. If it is not lying in the distal wrist crease, it may suggest that the patient has tried to commit suicide.

A review of in-patient hand infections.

A retrospective review is presented of 64 patients with infections of the hand requiring admission to hospital. We present an account of the different types of hand infection encountered, together with details of the various aetiologies and microbiological findings where these are available. The management of hand infections is discussed with reference to the patients in our series, and in terms of the general principles involved.

Replantation of digits or hands followed by destructive joint disease.

The clinical records and radiographs of 45 patients who had undergone replantation of a total hand, or a part thereof, were reviewed in order to determine the prevalence and the type of articular changes occurring distal to the site of anastomoses. In three patients, destructive joint changes were observed, consisting of bony fragmentation, spiculation, and cystic or erosive lesions. These changes, which developed between five and ten months after replantation, are most likely neuropathic or osteonecrotic in pathogenesis.
