OBJECTIVE: To study the clinical result of treating firearm-wound with the vessel pedicel tissue flap. METHODS: From May 1992 to October 2000, 21 cases of firearm-wound of upper limbs underwent transplantation with the vessel pedicel tissue flap. Of them, the locations of the wound were upper arm in 11 cases, forearm in 7 cases, hand in 3 cases. The size of wound was 1.0 cm x 0.5 cm to 8.0 cm x 6.5 cm; the wound course was 3 minutes to 8 hours with an average of 3 hours and 30 minutes. The patients were followed up 3 months to 2 years. RESULTS: In 21 cases, the results were excellent in 19 cases and poor in 2 cases. The good rate was 90.5%. CONCLUSION: Treatment of firearm-wound with vessel pedicel tissue flap has the good effect.
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.
Objective To investigate the feasibility and effectiveness of ulnar cortex transverse transport technique in treating upper extremity thromboangiitis obliterans (TAO). MethodsA retrospective analysis was conducted on the clinical data of 7 male patients with upper extremity TAO who were admitted and met the inclusion criteria between January 2019 and July 2022. The patients ranged in age from 32 to 50 years, with a mean age of 40.1 years. The disease duration ranged from 6 to 24 months, averaging 13.6 months. The smoking history ranged from 8 to 31 years, with a mean of 18.4 years. All patients presented with finger ulcers or gangrene, including 1 case affecting the thumb and index finger, 1 case affecting the index and middle fingers, 1 case affecting the middle and ring fingers, 1 case affecting only the ring finger, and 3 cases affecting the ring and little fingers. The preoperative visual analogue scale (VAS) score was 9.1±0.7. All patients underwent treatment with the ulnar cortext transverse transport technique. The wound healing time and the disappearance time of rest pain were recorded. The VAS score was used to assess the degree of hand pain before and after operation. Serum interleukin 6 (IL-6) levels were measured before operation and at 1 month after operation. Computed tomography angiography (CTA) of the affected limb was performed before operation and at 3 months after operation to evaluate changes in blood vessels. The clinical outcomes were evaluated at 1 year after operation based on the Patwa and Krishnan grading system. ResultsAll 7 patients were followed up 12-17 months, with an average of 13.7 months. All patients experienced successful healing of ulcers, with wound healing time ranging from 14 to 21 days, averaging 17.3 days. During the follow-up, no complication occurred, and there was no recurrence of ulcers. The disappearance time of rest pain ranged from 8 to 15 days, averaging 12.1 days. The pre- and post-operative (1-month) serum IL-6 levels were (25.1±5.9) pg/mL and (11.9±2.9) pg/mL, respectively, with a significant difference (t=5.363, P=0.002). CTA examination at 3 months after operation revealed partial revascularization of upper extremity arteries and establishment of collateral circulation, showing significant improvement compared to preoperative status. The VAS scores at 1, 7, 28 days, and 6 months postoperatively were 6.4±0.8, 3.7±0.8, 0.6±0.8, and 0.1±0.4, respectively, all of which significantly improved compared to preoperative scores (P<0.05). Furthermore, the VAS scores gradually decreased over time, with significant differences observed between postoperative time points (P<0.05). At 1 year after operation, the effectiveness of all 7 patients were evaluated as excellent based on the Patwa and Krishnan grading system. ConclusionThe ulnar cortex transverse transport technique can improve blood circulation in the upper limb of patients with TAO, reconstruct microcirculation, inhibit inflammation, promote ulcer healing, and alleviate limb pain.
Robot rehabilitation has been a primary therapy method for the urgent rehabilitation demands of paralyzed patients after a stroke. The parameters in rehabilitation training such as the range of the training, which should be adjustable according to each participant’s functional ability, are the key factors influencing the effectiveness of rehabilitation therapy. Therapists design rehabilitation projects based on the semiquantitative functional assessment scales and their experience. But these therapies based on therapists’ experience cannot be implemented in robot rehabilitation therapy. This paper modeled the global human-robot by Simulink in order to analyze the relationship between the parameters in robot rehabilitation therapy and the patients’ movement functional abilities. We compared the shoulder and elbow angles calculated by simulation with the angles recorded by motion capture system while the healthy subjects completed the simulated action. Results showed there was a remarkable correlation between the simulation data and the experiment data, which verified the validity of the human-robot global Simulink model. Besides, the relationship between the circle radius in the drawing tasks in robot rehabilitation training and the active movement degrees of shoulder as well as elbow was also matched by a linear, which also had a remarkable fitting coefficient. The matched linear can be a quantitative reference for the robot rehabilitation training parameters.
ObjectiveTo investigate the effect of virtual scene simulation training combined with midium frequency impulse electrotherapy on upper limb function and daily living ability of hemiplegia patients.MethodsFrom March to October 2019, 50 hemiplegic patients were recruited and randomly assigned to the trial group and the control group, with 25 patients in each group. The control group was given routine rehabilitation training, while the trial group was given virtual scene simulation training and medium frequency impulse electrotherapy on the basis of routine rehabilitation training. The Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Simple Test for Evaluating Hand Function (STEF), and Modified Barthel Index (MBI) were used to assess patients’ upper limb function and daily living ability before treatment and after 8 weeks of treatment.ResultsBefore treatment, the FMA-UE, STEF, and MBI scores of the trial group vs. the control group were 22.88±5.18 vs. 23.44±6.26, 40.12±4.82 vs. 41.44±4.54, and 51.40±7.29 vs. 48.60±7.00, respectively, and none of the between-group differences was statistically significant (P>0.05); after 8 weeks of treatment, the FMA-UE, STEF, and MBI scores of the two groups were 39.48±6.35 vs. 33.52±6.53, 59.08±7.54 vs. 52.52±5.83, and 71.00±8.78 vs. 62.40±9.37, respectively, and all of the between-group differences were statistically significant (P<0.05). After 8 weeks of treatment, the FMA-UE, STEF and MBI scores of the two groups of patients were significantly improved compared with those before treatment (P<0.05), and the improvement of each score of the trial group was significantlybetter than that of the control group (P<0.05). No stroke recurrence, electric burn, or other adverse reactions occurred in the two groups after treatment. ConclusionVirtual scene simulation training combined with midium frequency impulse electrotherapy can effectively improve the upper limb function of patients with hemiplegia and improve their quality of life.
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.

Objective To investigate the etiology, diagnosis, revascularization of upper l imb ischemia and the compl ications. Methods From March 2003 to February 2008, 72 cases of upper l imb ischemia were treated. There were 44males and 28 females, aged 19-90 years old (median 63 years old). The duration of the disease was 1 hour to 2 years. All cases had symptoms of l imb ischemia such as paleness, coldness, paralysis. According to individual condition, 72 patients accepted revascularizations including thromboembolectomy, reconstruction after traumatic injuries, pseudoaneurysm excision and angioplasty, balloon dilatation and stent implant, arterial repair, patch, vascular prosthesis or vein bypass/transplantation, and l igation or coarctation of fistula. Results Sixty patients (83.3%) recovered well after operation. Re-occlusion following thromboemboletomy was found in 6 patients (8.3%). And there were 4 patients (5.6%) with l imbs disturbance and muscles contracture and 2 patients (2.8%) with compartment syndrome in this series. The affected l imb had to be amputated in 2 patients (2.8%). And 1 patient (1.4%) died of cerebral hemorrhage because of anticoagulation 3 days after operation. All patients were followed up 1-6 years (mean 52 months) after operation. Four patients recurred and got improved after retreatments. The others got a good result with normal skin color and temperature, restoration of the radial and ulnar pulses, normal saturation of blood oxygen of finger ti p (gt; 90%) and patent blood flow of affected arteries was shown by color Doppler ultrasound. Conclusion The study indicates that identifying the etiology of upper l imb ischemia before operation and active revascularizations consistent with different causes are the key to treat the upper l imb ischemia.
