Objective To discuss the advantages and disadvantages of flaps in therepairment of soft tissue defects in upper extremity. Methods Based on the 2 609 cases of flaps in 2 512 patients from 1995 to 2004,the advantages and disadvantages of different sort of flaps, outcomes of treatment and indications of different soft of flaps were analyzed retrospectively. In the series, 2 089 pieces of the traditional flaps of different sorts were applied in 1 992 patients, 474 piecesof the axial flaps of different sorts were applied in 474 patients, different sorts of free flaps were used in 46 patients. Results Follow-ups were done for 1 month to 9 years (2.7 months in average). 2 531 flaps survived (97.01%); complete necrosis occurred in 10 flaps(0.38%); partial necrosis occurred in 68 flaps(2.61%). Of the 2 089 traditional flaps, 46 had partial necrosis(2.2%); 687 needed flap revisions(32.9%). Of the 474 axial flaps, 28 had complete or partial necrosis(5.9%); 82 needed revisions(17.3%). Of the 46 free flaps, 4 had complete or partial necrosis(8.7%) and nearly all the anterolateral flpas of thighs needed revisions.Conclusion Traditional flaps had the advantages of easy manipulation and the highest survival rate, however, also had the disadvantages of poor texture and many timesof operations. The flap with a pedicle had the advantage of good texture, consistent artery, free-range arc, however, the venous congestion was its disadvantage, which impaired the survival of the reverse flap. Free flap had the advantage ofgood texture and abandant donor site, but complicate manipulation was its shortage. Axial Flap with a pedicle is the optional choicefor repairing soft tissue defects in upper extremity.
Objective To study the effects of partial axillary lymph node dissection (PALD) on prognosis and upper limb function in patients with breast cancer. Methods Ninety-eight breast cancer patients with stage Ⅰ and Ⅱ were randomly divided into two groups and different surgical procedures following modified mastectomy were performed: partial axillary lymph node (level Ⅰ and Ⅱ) dissection (PALD) group (n=48) and total axillary lymph node (levelⅠ, Ⅱ and Ⅲ) dissection (TALD) group (n=50). The longterm positive relapse rate and upper limb function between 2 groups were compared. Results During the follow-up of 5 to 10 years (average 4.5 years), there were 2 cases (4.2%) of local recurrence on chest wall and one case (2.1%) of recurrence in axillary lymph node and one case (2.1%) of recurrence in supraclavicular lymph node in PALD group, and 2 cases (4.0%) of local recurrence on chest wall and no axillary lymph node recurrence and one case (2.0%) of recurrence in supraclavicular lymph node happened in TALD group. There was no statistical difference between PALD group and TALD group (Pgt;0.05). The incidence of upper limb edema and dysfunction was 4.2% (2/48) in PALD group and 16.0%(8/50) in TALD group (P＜0.01). There was no significant statistical difference of 5year and 10year survival rate between PALD group and TALD group (89.6% vs. 88.0%， 79.2% vs. 78.0%，Pgt;0.05). Conclusion PALD may reduce upper limb dysfunction after operation in patients with stage Ⅰ and Ⅱ breast cancer, and does not increase prognostic risk.
ObjectivesTo investigate the influence of the abduction angle of the upper extremities on the image quality of non-enhanced CT scan and clinical value of the patients who cannot lift with double upper limbs by vehicle accident.Methods60 patients with double upper limbs that could not lift by vehicle accidents were required to receive liver non-enhanced CT scan, the patients were divided into 3 groups according to the abduction angle (group A, B, C), 20 cases in each group, another 20 cases with standard pose as the control group (group D). The CT value and standard deviation of the liver region of interest, the erector and the background air were measured, and the contrast to noise ratio of liver images, image noise value were calculated, together with the assessment of image quality and statistic analysis.ResultsThe liver non-enhanced CT scan were completed successfully. The image quality of group D was significantly better than A, B, C (Z=–10.753, P<0.05;Z=–11.645, P<0.05;Z=–12.281, P<0.05), respectively. Group C was better than A and B (Z=–8.502, P<0.05;Z=–4.068, P<0.05), respectively. Group B was better than A (Z=–5.885, P<0.05). The CNR of the four groups of images increased gradually, group A (0.09±0.77), group B (1.56±0.83), group C (2.51±0.87), group D (2.59±0.97), respectively. There were significant differences between four groups (F=36.323, P<0.05). The image noise decreased systematically, group A (14.84±2.94), group B (13.04±1.59), group C (11.60±1.72), group D (10.44±1.13), respectively. There were significant differences between four groups (H=426.755, P<0.05).ConclusionOn the premise of safety inspection, with the enlargement of angle of the upper limbs of patients who cannot lift with double upper limbs by vehicle accidents, the image noise decreased and image quality is improved with the increase of signal noise ratio.
Objective To evaluate the long-term function of the traumaticallydamaged joint after its repair with transplantation of a fresh or a frozen allogenic joint. Methods From March 1977 to September 1993, 13 patients (9 males, 4females; age, 17-55 years) with traumatically-damaged joints underwent transplantation of the fresh or the frozen allogenic joints. Five patients had 5 damagedmetacarpophalangeal joints, 6 patients had 9 damaged interphalangeal joints, and 2 patients had 2 damaged elbow joints. So, the traumatic damage involved 13 patients and 16 joints. All the metacarpophalangeal joints and the interphalangeal joints were injured by machines and the 2 elbow joints were injured by road accidents. The patients were randomly divided into 2 groups: Group A (n=7) andGroup B (n=6). The 7patients with 8 joints in Group A underwent transplantation of fresh allogenic joints; the 6 patients with 8 joints in Group B underwent transplantation of frozen allogenic joints. The allogenic joint transplants were performed in the period from immediately after the injuries to 6 months after the injuries. The motion ranges of the transplanted joints and the X-ray films were examined after operation, and the immunological examination was performed at 8 weeksafter operation. Results The time for synostosis was 5-8 months in Group A, but4-6 months in Group B. In Group A, at 2 years after operation the metacarpophalangeal flexion was 30-40° and the interphalangeal flexion was 20-30°; however,at 6 or 7 years after operation the interphalangeal flexion was only 10-20°. The patients undergoing the transplantation with fresh elbow joints had the elbowflexion of 60° and the elbow extension of 0°, and had the forearm pronation of 30°and the forearm supination of 30°. But in Group B, at 2 years after operation the metacarpophalangeal flexion was 6070° and the interphalangeal flexionwas 40-50°; at 6 or 7 years after operation the interphalangeal flexion was still 40-50°. However, the patients undergoing the transplantation with frozen elbow joints had the elbow flexion of 90° and the elbow extension of 0°, and hadthe forearm pronation of 45° and a forearm supination of 45°. The joint motion ranges, the Xray findings, and the immunological results in the patients undergoing the transplantation of the frozen allogenic joints were significantly better than those in the patients undergoing the transplantation of fresh allogenicjoints. There was a significant difference in the immunological examination between Group A and Group B (IL2, 21.64±3.99；CD4/CD8,3.88±0.82 vs.IL-2,16.63±3.11；CD4/CD8, 2.53±0.23, P＜0.01). Conclusion Repairing the traumatically-damaged joints with frozen allogenic joints is a better method of regaining the contour, movement, and complex motion of the hands.

【Abstract】 Objective To investigate the operative techniques and cl inical results of repairing the soft tissue defectsof forearm and hand with free peroneal perforator-based sural neurofasciocutaneous flap. Methods From May 2006 toJanuary 2007, 6 patients including 5 males and 1 female were treated. Their ages ranged from 22 years to 51 years. They were injured by motor vehicle accidents (2 cases), or crushed by machines (4 cases), with skin defect of hand in 1 case, skin defect of hand associated with tendon injuries and metacarpal fractures in 2 cases, skin defect of forearm in 2 cases, and forearm skin defects with fractures of radius and ulna in 1 case. The areas of soft tissue defect ranged from 16 cm × 7 cm to 24 cm × 10 cm. The debridement and the primary treatment to tendons or bones were performed on emergency. And free flaps were transplanted when the wound areas were stable at 4 to 7 days after the emergent treatment. During the operation, the flaps were designed along the axis of the sural nerve nutrient vessels according to the shape and size of the soft tissue defects, with the peroneal perforator above the lateral malleolus as the pedicle and along with a part of the peroneal artery for vascula anastomosis. Then the flaps were harvested and transferred to the reci pient sites with the peroneal vartey anastomosed to the radial (or ulnar) artery and the peroneal veins to one of the radial (or ulnar) veins and the cephal ic vein, respectively. The flap size ranged from 18 cm × 8 cm to 25 cm × 12 cm. The donor areas were closed by skin grafts. Results The 5 flaps survived after the surgery. Partial inadequate venous return and distal superficial necrosis happened in only 1 case, which also got secondary heal ing by changing dressing and anti-infective therapy. The donor sites reached primary heal ing completely. The followed-up in all the patients for 6 to 13 months revealed that the appearance and function of the flaps were all satisfactory, and no influence on ambulation of donor site was found. Conclusion Peroneal perforator-based sural neurofasciocutaneous flap has the advantages of favourable appearance, constant vascular pedicle, rel iable blood supply, large size of elevation and minor influence on the donor site. And the free transfer of this flap is an ideal procedure to repair the large soft tissue defects of forearm and hand.
With the aging of the society, the number of stroke patients has been increasing year by year. Compared with the traditional rehabilitation therapy, the application of upper limb rehabilitation robot has higher efficiency and better rehabilitation effect, and has become an important development direction in the field of rehabilitation. In view of the current development status and the deficiency of upper limb rehabilitation robot system, combined with the development trend of all kinds of products of the upper limb rehabilitation robot, this paper designed a center-driven upper limb rehabilitation training robot for cable transmission which can help the patients complete 6 degrees of freedom (3 are driven, 3 are underactuated) training. Combined the structure of robot with more joints rehabilitation training, the paper choosed a cubic polynomial trajectory planning method in the joint space planning to design two trajectories of eating and lifting arm. According to the trajectory equation, the movement trajectory of each joint of the robot was drawn in MATLAB. It laid a foundation for scientific and effective rehabilitation training. Finally, the experimental prototype is built, and the mechanical structure and design trajectories are verified.
Objective To discuss the reconstructive method of the bone defect after resection of the upper extremity bone tumor and to assess the outcome of the autograft to reconstruct the bone defect after the bone tumor resection. Methods From August 1998 to March 2004,16 patients aged 7~45 years suffering from bone tumor of the upper extremity were treated with the wide resection of the bone tumor and the reconstruction of the bone defect by the autograft. The following diagnoses were confirmed by pathological examination:Ewing’s sarcoma and osteosarcoma of theproximal humerus in 1 patient each; Ewing’s sarcoma of the distal humerus in 2 patients;giant cell tumor in 8 patients, highgrade chondrosarcoma in 2, malignant fibrohistiocytoma in 1; and osteosarcoma in 1 of the distal radius. Substitution of the proximal humerus with the clavicle was performed in 2 patients, andthedistal humerus with the fibula in other 2 patients. Of the 12 patients with tumor in the distal radius, 1 was reconstructed with autograft of the iliac bone and 11 with autograft with the fibula. The functional outcome was evaluated by the MSTS score. Results The follow-up for 36 and 12 months respectively revealed that in the 2 patients undergoing the autograft with the clavicle in the proximal humerus, good shoulder functions of flexion and extension were obtained although the function of abduction was poor, with the MSTS scores of 23 and 22 respectively. In the 2 patients undergoing the autograft with the fibular in the distal humerus, good elbow function and bone union were observed according to the followup for 3 and 4 months respectively, with the MSTS scores of 24 and 19 respectively. Of the 12 patients undergoing the autograft in the distal radius, 11 had an excellent or good function with no complication, with the average MSTS score of 22.6 (ranging from 18 to 27), accordingto the follow-up for 6-75 months; only 1 had no bone union 10 months after operation and lost the follow-up afterwards. Conclusion Reconstruction ofthe bone defect with the autograft after the wide resection of the upper extremity bone tumor is an ideal and reliable method for some suitable patients, especially for some children.
