All patients were treated by supermicrosurgery combined with modified anterograde replantation method. The modified anterograde replantation method was according to proportional anastomosis of arteries and veins, the proceed was artery and nerve → fixation of bone → anastomosis of subcutaneous vein → suturing of skin wound. In the procedure of anastomosis of arteries and nerves, the position of injured finger replantation was modified, the customary horizontal position was altered to vertical position, the severed finger was flipped to the palmar side which was taken as the rotation axis, and the anastomosis was performed through the dorsal approach. Both the proximal and distal sections was completely exposed in the position, so that the visual angle of the surgeon was changed from squint to direct vision, and which suitable for the observation and operation. Follow-up was performed in outpatient department and WeChat after surgery, and functional evaluation was recorded according to the trial standard for functional evaluation of replantation of severed finger of Hand Surgery Society of Chinese Medical Association.Results:All of 38 patients were involved, including 23 males and 15 females. The mean age was 27.3 years (ranged from 1 to 58 years). All of injured fingers were completely severed in Yamano Ⅰ zone by single finger. The causes of injuries included chainsaw injury( n=6), knife cutting injury ( n=5), crush injury ( n=19), and avulsion injury ( n=8). According to the classification of Yamano Ⅰ zone, there were 4 cases of type Ⅰ, 14 cases of type Ⅱ, 11 cases of type Ⅲ, 6 cases of type Ⅳ and 3 cases of type Ⅴ. There were 12 cases of thumb, 9 cases of index finger, 6 cases of middle finger, 7 cases of ring finger and 4 cases of little finger. The ischemia time was 1-12 h. The survival rate was 94.7% (36/38). Thirty-three patients were followed up for 6-12 months. The length and shape of the fingers were similar to the contralateral finger, the nail was intact, and the two-point discrimination was 3-5 mm. The hand function returned to normal. Conclusions:The supermicrosurgery combined with modified anterograde replantation in Yamano Ⅰ zone can be used for the replantation of fingertip with arterial and venous anastomosis. The replantation fingertip has a high survival rate, satisfactory function and appearance. It is an ideal choice for the treatment of amputated finger in Yamano Ⅰ.

Objective:To investigate the clinical effect of free medial sural artery perforator flap (MSAP) in repairing skin and soft tissue defects of hand and foot.Methods:The clinical data of patients with soft tissue defects of hand and foot who were treated by the free MSAP in Xuzhou Renci Hospital from January 2017 to December 2019 were analyzed retrospectively. When repairing the wound of the foot, the donor site was harvested from the ipsilateral lower limb; when repairing the wound of the hand, the donor site was harvested from the ipsilateral or contralateral lower limb. Regular follow-up was carried out through outpatient reexamination, WeChat and telephone. The hand scoring criterion was the upper extremity functional evaluation standard set up by the Chinese Society of Hand Surgery of the Chinese Medical Association; the foot scoring criterion was the Maryland score system.Results:All 10 patients were involved, including 5 males and 5 females. The mean age was 44.8 years (ranging from 16 to 56 years). There were 8 cases of hand wounds and 2 cases of and foot wounds. The MSAP size was 4.0 cm×7.0 cm-5.0 cm×14.0 cm. The lower leg donor site was closed primarily. The cutaneous nerves were anastomosed in seven cases. All flaps survived in 10 patients and primary healing after the operation. One flap had a vascular crisis after the operation and survived after the vascular exploratory operation. Nine cases were followed up for 6-12 months; the mean follow-up time was 8 months. the MSAP was in good shape, the sensation of the flap recovered to grade S2-S3, and the two-point discrimination was 7-9 mm. The hand and foot function returned to normal. The flap in the weight-bearing area was not broken. The movement and sensation of the lower limbs in the donor area were normal without dysfunction. At the last follow-up, hand function was evaluated: 6 cases were excellent and 1 case was good; the evaluation of foot function was excellent in 2 cases. One patient was lost to follow-up.Conclusions:The free MSAP does not damage the main blood vessels; the perforating branches are relatively constant, the vascular pedicle is long, and the subcutaneous fat layer is thin. The effect of repairing the wound of hand and foot is good.

Objective:To investigate the effect of the Ilizarov technique in the treatment of post-traumatic lower extremity shortening with talipes equinovarus.Methods:Clinical data of patients with post-traumatic lower extremity shortening and talipes equinovarus treated by the Ilizarov technique in the Department of Orthopaedics of Xuzhou Renci Hospital from January 2013 to April 2020 were retrospectively analyzed. The annular external fixator was installed on the affected limb according to the Ilizarov principle of external fixation. 3 days after the operation, the internal and lateral screw rods were adjusted at the speed of 2 mm/d to gradually correct the talipes equinovarus. 7 days after surgery, the lower leg was lengthened at a speed of 1 mm/d. After the foot was corrected, the foot external fixator was continued to be worn for 4 to 6 weeks, and then the fixator was removed and the foot was immobilized with a brace for 6 to 8 weeks. The lower leg fixator was removed after the lower extremity length was restored and the bone mineralization at the extension site was good. The length of both lower extremities, angle of talonavicular joint, angle of plantar flexion and dorsal extension of the ankle, and range of motion of ankle were compared before surgery and at the last follow-up. At the last follow-up, the affected feet were scored and rated using the International Clubfoot Study Group (ICFSG) scoring system, which was divided into four grades: excellent, good, medium, and poor. SPSS 25.0 software was used for statistical analysis, and each measurement index and ICFSG score were expressed in Mean±SD. Paired t-test was used to compare the preoperative and last follow-up data, and P<0.05 was considered statistically significant. Results:A total of 31 patients were enrolled, including 17 males and 14 females. The age was 15-18 years old, with an average of 16.5 years old. There were 16 cases on the right side and 15 cases on the left side. The lower extremity shortening was 45-75 mm, with an average of 65 mm. The fixation time of the external fixator was 4.5-6 months after surgery, with an average of 5 months, and the follow-up time was 22-28 months, with an average of 25.5 months. The length of the affected lower extremity recovered, the shape was basically satisfactory, and the plantar gait was restored. At the last follow-up, compared with the preoperative period, the anteroposterior talocalcaneal angle of the foot (23.0°±2.1° vs. 8.5°±2.6°), from lateral talocalcaneal angle the foot (27.0°±4.3° vs. 11.2°±4.4°), ankle plantar flexion angle (24.5°±6.8° vs. 51.1°±6.5°), ankle dorsiflexion angle (5.8°±3.5° vs. -46.8°±7.0°) and ankle range of motion (30.3°±8.2° vs. 4.2°±1.6°) were statistically significant ( P <0.01). ICFSG score: The points at the last follow-up (8.0 ± 4.2) were significantly lower than that before the operation (41.9 ± 5.3) ( P<0.01), of which 18 were excellent, 9 were good, and 4 were medium. Two cases had recurrent deformities in the later stage, and the results were satisfactory after the fusion of the talonavicular joint and calcaneocuboid joint and the anteposition of the posterior tibial tendon in the second stage. There were 4 cases of toe contracture deformity, which did not recur after the release of the flexor digitorum longus tendon at the toe. Anterior ankle impingement was observed in 5 cases and improved after the arthroscopic osteophyte removal. After the lower extremity extension was in place, the external fixator was replaced by the intramedullary nail for walking in 6 patients. The infection of the nail path occurred in 7 cases, which improved after replacement of fixing pins and dressing change of the nail path. Conclusion:The application of the Ilizarov technique in the treatment of post-traumatic lower extremity shortening with talipes equinovarus has the advantages of small trauma and dynamic control of deformity correction, which can achieve good result.

Objective To explore the possibility of reduce the treatment cycle of post-traumatic osteomyelitis patients treat with bone transportations. Methods In February, 2017, a patient was diagnosis as left tibial os-teomyelitis with soft tissue defects and treated. Before start trifocal bone transportation with Orthofix external fixator, we did preoperative practice with computer and model. Except this case we also had some article review in this report. Results This case not only finished 12.5 cm bone transportation in 45 days but also treated soft tissue defect before bone transportations. In this method we save almost 2/3 time to compare with monofocal bone transportations, and frame time were also faster than previous method. But because of some mishaps when we follow-up, the gap was occurred in docking side after 140 days follow-up that may need bone transplants. After 140 days of operation, the gap was disap-peared. Conclusion A new type bone transportations in this study and it may reduce treatment time of osteomyelitis.
