Objective To investigate the etiology of the flexor contracture of the hand, to diagnose and to explore its surgical treatment. Methods From May 1997 to June 2004, 212 cases of flexor contraction of the hand were treated with scar excision, thorough loosening the contracture, covering the secondary skin defects with free skin grafting, “Z”plasty, double “V-Y” plasty, transposition of the palmar dorsum flap of the hand and iliac-inguinal flap. There were 163 males and 49 females, whose ages ranged from 3 to 61. There were 85 cases of left hands, 54 cases of right hands, and 73 cases of both hands. Contracture sites were as follow: 117 cases were in fingers, 32 cases located in palms and 63 cases were in both. Causes of deformity were as follow: 29 cases derived from burn and explosion, 127 cases came from contracture of palmar aponeurosis, 31 cases were because of traffic accident and machine extrusion, 5 cases for getting an electric shock, 14 cases for improper postoperative immobility, and 6cases for other reasons. Course of diseases lasted for 2 to 24 months.Results 149 cases were followed up for 4 to 30 months. One fingertip was in necrosis and ended in nub plasty because of inappropriate time to leave hospital. Flexion contracture recurred in 7 cases, skin necrosis occurred to 3 cases whose scars were healed in the end, poor restoration of function was observed in 2 children patients for lack of exercise, and 2 skins contracted after free cut skin grafting. Others got satisfactory results. Conclusion Once the pathogenesis and contrature factors are clearly known, timing and correct surgical measures are chosen, thorough contracture is loosened, and early postoperative exercises are performed, good effect will be achieved.
OBJECTIVE: To explore a new surgical management of multiple fingers degloving injury. METHODS: In 1994 to 1997, 47 cases with multiple fingers degloving injury were sutured by two reverse "s"-type skin flaps on abdominal flank. RESULTS: The skin flaps in 46 cases survived and the wounds obtained primary heal. CONCLUSION: The application of abdominal flank "s"-type skin flap is reliable and convenient in the treatment of multiple fingers degloving injury.
OBJECTIVE: To investigate the clinical effect of skin flaps repairing severe thermopressure injury of hand. METHODS: From January 1989 to December 1998, 112 patients with severe thermopressure injury of hand were repaired by various skin flaps transfer, the size of skin flaps was 6 cm x 8 cm to 12 cm x 18 cm. Postoperative patients were treated by combined rehabilitation in early stage. RESULTS: All the flaps were survived with satisfactory effect. Sixty-six patients were followed up 6 to 12 months, skin flaps all showed better colour and texture, and function of the hand was satisfactory. CONCLUSION: Different skin flaps are adopted to repair severe thermopressure injury of the hand according to different skin defects of the hand, combined early rehabilitation treatment, to achieve good recovery of function and appearance of the hand to the greatest extent.
OBJECTIVE This paper is aimed to observe the long-term result of reconstruction of wrist joint by replacing distal end of radius with vascularized fibular head in patient of giant tumor. METHODS From July 1978 to November 1993, 12 cases of giant tumor of distal end of radius were treated by this procedure and followed up for 6 months to 15 years, and the movement range of wrist, grip strength, and pain were evaluated. RESULTS The painful wrist released in 11 cases, only one case still existed mild pain and felt discomfortable. The average range of movement of wrist joint was 34.05 degree in volar flexion, 52.80 degree in dorsal extension, 26.25 degree in ulnar deviation, and 19.75 degree in radial deviation, and average grip strength was 44.6 kg. Compared with the contralateral side, there were accounted for 46.2%, 72.7%, 76.1%, 80.6%, and 76.7% respectively. CONCLUSION Replacement of distal end of radius with fibular head to reconstruct wrist joint can restore function of carpal joint, which is proved to be a safe and effective method.
Objective To establish a new operative method to repair defects of palm and proximal fingers with double vascular pedicle flaps. Methods From August 1992 to June 2000, 20 cases of soft tissue defects of palm and fingers were repaired with double vascular pedicle flaps. Twenty patients included 9 males and 11 females, aged 17-35 years. The causes were crush,avulsion, and so on. The interval between injury and operation was 3-11 hours.The wound area ranged from 8 cm×12 cm to 10 cm×20 cm. We devised the two side flaps on pectoral-umbilical place with well-known blood vessel to cover flexion and extension regions of palm and the multi-lobes skin flap to cover defect of fingers simultaneously. Results Out of 20 patients, 19 were followed up 8-12 months with an average of 9.8 months. All the flaps survived completely. The skin colour and the contour of the palm and digits were good. Conclusion The double vascular pedicle flap is one of the best choices torepair soft tissue defect of the palm and proximal fingers; the procedure is simple and the operation is extended easily.
Objective To investigate the procedure and applications ofantegrade and retrograde dorsal metacarpal flaps with cutaneous branches as pedicles in repairing soft tissue defects of wrist and fingers. Methods From 1995 to 2003, we observed that the proximal and distal branches, deriving from the dorsal metacarpal artery, formed a consistent anastomosis arc subdermally. The anastomosis arc was paralleled to the dorsal metacarpal artery. Antegrade and retrograde dorsal metacarpal flaps could be designed using proximal anddistal branches as pedicles. Twenty-seven cases of soft tissue defects were treated by use of dorsal metacarpal flaps with cutaneous branches as pedicles, including 3 cases of defects on dorsum of hand with antegrade flaps, and 24 cases of defects on fingers with retrograde flaps ( index finger:12 cases; middle finger: 6 cases; ring finger: 4 cases; and little finger:2 cases). The dimensions of the antegrade flaps were 2.0 cm×4.0 cm～4.0 cm×6.0 cm, and the dimensions of theretrograde flaps were 2.5 cm×3.5 cm～3.0 cm×7.0 cm.The incision of the donor site was closed directly. Results All flaps survived. After a follow-up of 13 years, the texture and color of the flaps were good, and the shape and function of the donors were normal. Conclusion The antegrade or retrograde flap pedicled with the distal or proximal cutaneous branches of thedorsal metacarpal artery, is an optimal flap in repairing finger or wrist softtissue defects.
Objective To investigate the outcome of repairing hand composite defects using pedicle osteocutaneous groin flap. Methods From February 1998 to May 2004, 33 cases of hand composite defects were repaired with pedicle osteocutaneous groin flap. There were 22 males and 11 females. The age was 19 to 54 years with an average of 243 years. The defect was caused by palmar penetrating injury in 17 cases, by dorsal hand crushing injury in 9 cases and by other injury in 7 cases. Twentythree cases complicated by metacarpal defect, 10 by phalanx defect. Thesize of skin defect was 3.5 cm×2.0 cm to 15.0 cm×10.0 cm, the size of bonedefect was 1.5 to 3.5 cm. After 3 to 7 days of primary debridement, defect was repaired by the pedicle osteocutaneous groin flap based on the superficial circumflex iliac vessels. The flap size was 4.0 cm×2.5 cm to 17.0 cm×11.0 cm. Results All the osteocutaneous flaps survived. During the 4 to 22 months follow-up postoperatively, thetexture, appearance and function of the flap were excellent and bone union was obtained in all cases after 7 to 9 weeks of operation.Conclusion The pedicle osteocutaneous groin flap is an ideal flap to repair the composite defect of the hand, with the benefit of simple procedure and reliable blood supply.
Objective To summarize the clinical experiences of various types of the second dorsal metacarpal artery (SDMA) flap for hand reconstruction. Methods From 1988 to 2003, 139 SDMA flaps were transferred for hand injuries. The flaps were used in 5 types according to vascularization and technique in transplantation:orthograde pedicled island SDMA flaps in 37 cases (cutaneous in 24and teno-cutaneous in 13), retrograde pedicled island SDMA flaps in 25 cases(cutaneous in 19 and teno-cutaneous in 6),double pivot SDMA flaps in 36 cases(cutaneous in 28 and teno-cutaneous in 8), distal perforator branch pedicledflaps in 19cases (cutaneous in 16 and composite in 3), free SDMA flaps in 22 cases (cutaneous in 15 and composite in 7). The skin islands were 3.0 cm×1.5 cm to 6.3 cm×5.0 cm in size. Results Of the 139 flaps, 135 flaps survived completely, 3 survived partially, and1 failed in the operation because of intractable vascular spasm. Follow-up wasdone in 116 cases for 12 to 57 months. The flap had good texture and color match. The twopoint discrimination was 5 to 9 mm in 78 sensate flaps, while it was 10 to 15 mm in 38 nonsensate flaps. In 21 tenocutaneous flaps, the TAM score of range of motion was 60% to 70% of the healthy side. Conclusion The SDMA flap has a constant and reliable vessel and a thin, pliable, and good-quality skin. It is versatile in creatingcomposite flaps. It is a good flap resource for hand and finger reconstruction.

Methods
From June to August 2016, several healthcare workers from clinical departments and nosocomial infection control department in Chengdu were selected by purposive sampling method. Data was collected by individual in-depth interviews, and was three-rank coded by Nvivo 8 software based on Grounded Theory.
Results
After three-rank coding, 6 important influencing factors were generalized which were re-categorized into 3 levels: personal cognition, behavior capacity and social support. At the last, the whole framework of the theory was constructed through core coding.
Conclusion
In clinical practice, we should take reasonable measures to strengthen the training of hand hygiene, improve the hand hygiene facilities, strengthen supervision and management, and effectively improve the implementation rate of hand hygiene.
A series of 28 cases of fractures of the small tubular bones of the hand, including Bennetts fracture, were treated with the minor unilateral multifunctional external fixator. After manipulation, a hole was drilled on the proximal and distal parts of the fractured bone. Hand in functional position, the external fixator was set in place. Functional exercises were begun after the fixation. The patients were follwed up for two to six months. The average healing time was thirtyfive days. The average healing time for Bennett’s fractures was twentyeight days, and for the fractures of metacarpal bone was forty-two days. There were no deformity and complication of infection following external fixation.The functional recovery of the hands was satisfactory. The fixator had the following advantages: It was simple and had tight fixation; fractures with infection, was still indicated and could be adjusted according to the clinical purpose.
