OBJECTIVE: To compare clinical efficacy of No-touch technique and traditional retractor in treating calcaneal fracture. METHODS: Clinical data of 74 calcaneal fracture patients with closed Sanders typeⅡ to Ⅳ were retrospectively analyzed from July 2019 to June 2021. According to different treatment methods, the patients were divided into No-touch group and conventional group, 37 patinets in each group. In No-touch group, there were 25 males and 12 females, aged from 19 to 70 years old with an average of (42.64±14.16) years old;17 patients were typeⅡ, 14 patinets with type Ⅲ, 6 patients with type Ⅳ according to Sanders fracture classification;three 2.0 mm Kirschner wires were implanted into the talus body, talus neck, and cuboid bone, and the flap was turned upward to expose the operation area. In conventional group, there were 30 males and 7 females, aged from 19 to 67 years old with an average of (41.56±11.38) years old;17 patients with typeⅡ, 12 patients with type Ⅲ, 8 patients with type Ⅳ according to Sanders fracture classification;the operation was completed by exposing the operation area with traditional retractor. Operation time, postoperative incision complications, postoperaive American Orthopedic Foot and Ankle Society (AOFAS) ankle hind foot score at 6 months between two groups were compared. RESULTS: Seventy-four patients were followed up, and follow-up time in No-touch group ranged from 6 to 17 months with an average of(9.57±2.72) months, while in conventional group ranged from 6 to 16 months with an averge of(9.14±2.71) months, and no difference in follow-up between two groups (P>0.05). Operation time in No-touch group (55.67±7.94) min was shorter than that in conventional group (70.16±9.41) min (P<0.05);four patients in No-touch group occurred incision complications, while 8 patients in normal group, and had statistically difference(P<0.05). Daily activities and support, maximum walking distance (block), ground walking, limited degree of flexion, extension and valgus, foot alignment and total score of AOFAS scores in No-touch group was significantly higher than that of conventional group (P<0.05). There were no significant difference in pain degree, abnormal gait and ankle hind foot stability between two groups(P>0.05). According to AOFAS score, 19 patients got excellent result, 16 good and 2 poor in No-touch group;while 9 excellent, 24 good, and 4 poor in conventional group, and no difference between two groups (P>0.05). CONCLUSION Compared with traditional retractor in treating calcaneal fracture, No-touch technology could significantly shorten operation time, reduce incidence of postopertive complications, while two methods could improve excellent and good rate of ankle joint function recovery after operation.

OBJECTIVE: To investigate clinical effect of percutaneous reduction combined with internal fixation of calcaneal nail in treating Sanders typeⅡto Ⅲ calcaneal fractures. METHODS: From July 2017 to August 2019, clinical data of 98 patients with Sanders typeⅡto Ⅲ calcaneal fractures treated were retrospectively analyzed, and divided into observation group and control group according to different surgical methods. In observation group, there were 35 males and 21 females, aged from 23 to 58 years old with an average of (34.50±7.81) years old;29 patients with Sanders typeⅡand 27 patients with Sanders type Ⅲ;30 patients on the left side and 26 patients on the right side;the time from fracture to operation ranged from 1 to 4 days with an average of (3.45±0.54) days;and treated with percutaneous reduction combined with internal fixation of calcaneal nail system. In control group, there were 25 males and 17 females, aged from 25 to 60 years old with an average of (35.27±7.64) years old;23 patients with Sanders type Ⅱ and 19 patients with Sanders type Ⅲ;24 patients on the left side and 18 patients on the right side;the time from fracture to operation ranged from 2 to 5 days with an average of (3.42±0.62) days;and treated with open reduction and internal fixation. Operation time, blood loss, hospital stay, fracture healing time, and postoperative visual analogue scale (VAS) at 1 day, preoperative and postoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Böhler angle, Gissane angle and calcaneus width, and postoperative complications were compared between two groups. RESULTS: All patients were followed up from 13 to 18 months with an average of (15.6±2.2) months. There were significant differences in operation time, blood loss, hospital stay, fracture healing time and postoperative VAS at 1 day between two groups (P<0.05). There was statistical difference in postoperative AOFAS score at 12 months between two groups (P<0.05), and AOFAS score at 12 months after operation was higher than that before operation (P<0.05). According to AOFAS score, 21 patients got excellent result, 30 good and 5 moderate in observation group, and 10 excellent, 22 good, 7 moderate and 3 poor in control group, which had statistical difference between two groups (P<0.05). Postoperative Böhler angle, Gissane angle and calcaneus width at 6 months were better than that before operation between two groups(P<0.05). One patient in observation and 20 patients in control group occurred skin numbness after operation, and 14 patients occurred skin necrosis in control group, there were obvious difference between two groups(P<0.01). CONCLUSION Compared with open reduction and internal fixation, percutaneous reduction combined with internal fixation system in treating Sanders typeⅡto Ⅲ calcaneal fractures is feasible for fracture repair without waiting for foot deswelling, which could accurately restore normal shape and position of the fractured heel bone, completely eliminate fracture malunion, and reduce postoperative complications. Therefore, it could shorten operation time, hospital stay, fracture healing time, reduce amount of blood loss, promote postoperative recovery, and less complications, high safety, which could be used as a choice of orthopedic surgery for foot and ankle trauma.

OBJECTIVE: To explore clinical effect of intermittent flap opening technique in L-shaped incision of calcaneal fracture. METHODS: From January 2017 to January 2019, 48 patients with Sanders typeⅡ to Ⅳ calcaneal fractures were treated by open reduction and internal fixation. According to different flap opening techniques, the patients were divided into control group and observation group, 24 patients in each group. In observation group, there were 17 males and 7 females, aged from 20 to 60 years old with an average of(45.12±9.56) years old;7 patients were typeⅡ, 10 patients were type Ⅲ and 7 patients were type Ⅳ according to Sanders classification;3 patients were C0, 16 patients were C1 and 5 patients were C2 according to Tscherne-Gotzen soft-tissue assessment;treated with intermittent flap technique. In control group, there were 19 males and 5 females aged from 20 to 60 years old with an average of (47.32±10.67) years old;7 patients were typeⅡ, 11 patients were type Ⅲ and 6 patients were type Ⅳ according to Sanders classification;2 patients were C0, 18 patients were C1 and 4 patients were C2 according to Tschemc-Gotzen soft-tissue assessment;treated with static flap opening technique. Operation time, flap retraction time, changes of Böhler angle and Gissane angle before and after operation at 3 days, and occurrence of incision complications were observed and compared between two groups. RESULTS: All patients were followed up from 3 to 6 months with an average of(4.52±1.01) months. There were no significant differences in operation time, changes of Böhler angle and Gissane angle before and after operation at 3 days between the two groups(P>0.05);there was statistical difference in flap retraction time between two groups(P<0.05). Occurrence of incision complications in observation group was significantly lower than that in control group (P<0.05). CONCLUSION Intermittent flap opening technique is superior to static opening technique in reducing incision complications of lateral "L" approach of calcaneus. Single Kirschner wire opening does not affect the exposure, reduction and fixation of fracture during operation.

The paper summarizes the academic thought and clinical experience of professor LI De-hua in treatment of facial nerve injury after total parotidectomy with blade needle based on jingjin (muscle region of meridian, sinew/fascia) theory. This disease is located at muscle regions of hand-/foot-three yang meridians; and the sinew/fascia adhesion is its basic pathogenesis, manifested by "transversely-distributed collaterals" and "knotted tendons". In treatment, the knotted tendons are taken as the points. Using the relaxation technique of blade needle, the lesions of sinews/fascia are dissected and removed to release the stimulation or compression to the nerves and vessels so that the normal function of sinews/fascia can be restored.

OBJECTIVE: To investigate the clinical effect the treatment of arthroscopy-assisted calcaneal spur resection combined with plantar fascia release and calcaneal decompression in the treatment of the patients with intractable calcaneal pain. METHODS: The clinical data of 50 patients with intractable heel pain from January 2016 to January 2019 were retrospectively analyzed, including 20 males and 30 females;aged from 40 to 68 years old with an average of (50.12±7.35)years old, the medical history ranged from 1 to 4 years. All patients underwent arthroscopy-assisted calcaneal spur resection combined with plantar fascia release and calcaneal decompression, and were followed up, the duration ranged from 24 to 60 months with an average of(42.00±3.28) months. All patients had obvious heel pain before surgery, and X-ray examinations often showed the presence of calcaneal spurs. In addition to the routine foot examination, the changes in the height and angle of the arch of the foot were also measured pre and post-operatively by X-ray, for the evaluation of clinical effect. The VAS system was used to evaluate the degree of foot pain;the AOFAS scoring system was used to comprehensively evaluate the foot pain, voluntary movement, gait and stability. RESULTS: The VAS decreased from (8.75±1.24) before surgery to (5.15±2.35) at 3 months after surgery, (4.07±2.53) at 6 months after surgery, and (3.95±2.44) at the last fllow-up(P<0.05). The AOFAS score increased from (53.46±4.17) before surgery to(92.46±2.53) at 3 months after surgery, (96.33±2.46) at 6 months after surgery, and (97.05±2.37) at the last follow-up(P<0.05). The arch height was (41.54±1.15) mm before operation and (41.49±1.09) mm after the operation, the difference was not statistically significant(P>0.05). The internal arch angle of the foot arch was (121±6)° before operation and (122±7)° after operation. The difference was not statistically significant(P>0.05). CONCLUSION Arthroscopy-assisted calcaneal bone spurs resection combined with plantar fascia release and calcaneal decompression exhibited great clinical effect for treating intractable heel.

OBJECTIVE: To investigate the effectiveness of tibial transverse transport (TTT) combined with modified neurolysis in treatment of diabetic foot ulcer (DFU) through a prospective randomized controlled study. METHODS: The patients with DFU and diabetic peripheral neuropathy, who were admitted between February 2020 and February 2022, were selected as the research objects, of which 31 cases met the selection criteria and were included in the study. The patients were divided into two groups by random number table method. The 15 patients in the trial group were treated with TTT combined with modified neurolysis, and the 16 patients in the control group received treatment with TTT alone. There was no significant difference in gender, age, duration of DFU, ulcer area, Wagner classification, as well as preoperative foot skin temperature, visual analogue scale (VAS) score, ankle-brachial index (ABI), motor nerve conduction velocity (MNCV) of the common peroneal nerve, MNCV of the tibial nerve, MNCV of the deep peroneal nerve, two-point discrimination (2-PD) of heel, and cross-sectional area (CSA) of the common peroneal nerve between the two groups ( P>0.05). The time for ulcer healing, foot skin temperature, VAS scores, ABI, 2-PD of heel, and CSA of the common peroneal nerve before operation and at 6 and 12 months after operation were recorded and compared between groups. The differences in MNCV of the common peroneal nerve, MNCV of the tibial nerve, and MNCV of the deep peroneal nerve between pre-operation and 12 months after operation were calculated. RESULTS: All patients in both groups were followed up 12-24 months (mean, 13.9 months). The surgical incisions in both groups healed by first intention and no needle tract infections occurred during the bone transport phase. Ulcer wounds in both groups healed successfully, and there was no significant difference in the healing time ( P>0.05). During the follow-up, there was no ulcer recurrences. At 12 months after operation, the MNCV of the common peroneal nerve, the MNCV of the tibial nerve, and the MNCV of the deep peroneal nerve in both groups accelerated when compared to preoperative values ( P<0.05). Furthermore, the trial group exhibited a greater acceleration in MNCV compared to the control group, and the difference was significant ( P<0.05). The foot skin temperature, VAS score, ABI, 2-PD of heel, and CSA of the common peroneal nerve at 6 and 12 months after operation significantly improved when compared with those before operation in both groups ( P<0.05). The 2-PD gradually improved over time, showing significant difference ( P<0.05). The 2-PD of heel and VAS score of the trial group were superior to the control group, and the differences were significant ( P<0.05). There was no significant difference in ABI, foot skin temperature, and CSA of the common peroneal nerve between groups after operation ( P>0.05). CONCLUSION Compared with TTT alone, the TTT combined with modified neurolysis for DFU can simultaneously solve both microcirculatory disorders and nerve compression, improve the quality of nerve function recovery, and enhance the patient's quality of life.

OBJECTIVE: To explore asurgical methods for replantation of severed finger. METHODS: From January 2018 to November 2022, 8 amputated-finger patients were performed surgical reconstructions by using polyfoliate free flaps with the first dorsal metatarsal artery, including 7 males and 1 female, aged from 20 to 55 years old, and defect areas ranged from (1.0 to 2.0) cm×(3.0 to 4.5) cm. Finger pulp sensation, shape and other relevant parameters were assessed following the upper extremity functional evaluation standard, which was put forward by Hand Surgery Branch of Chinese Medical Association. And maryland foot functional score was used to evaluate foot function. RESULTS: Amputated fingers and flaps of all the 8 patients were survived. All patients were followed up for 4 to 20 months, their finger color and temperature tured to normal, with good wear-resistance and cold-resistance. According to Hand Surgery Branch of Chinese Medical Association, functional score ranged 61 to 92;4 patients got excellent result and 4 good. Maryland foot functional score ranged from 93 to 100;and 8 patients got excellent result. CONCLUSION It is feasible to repair severed fingers with soft tissue defects using polyfoliate free flaps that driven by the flippers of the first and second toes of the foot. This method ccould bridge blood vessels, increase soft tissue volume of the injured finger, and avoid finger shortening, with high patient satisfaction.

OBJECTIVE: To investigate the clinical effect of the tarsal sinus approach combined with Herbert screw and minimally invasive calcaneal locking plate compared with traditional lateral L-shaped incision approach combined with plate internal fixation in the treatment of SandersⅡ and Ⅲ calcaneal fractures. METHODS: Total of 110 patients with SandersⅡ and Ⅲ calcaneal fractures admitted from March 2018 to March 2020 were selected. There were 66 males and 44 females, ranging in age from 20 to 72 years old, with an average of (48.82±8.03) years old. There were 48 SandersⅡ patients and 62 Sanders Ⅲ patients, including 41 left calcaneal fractures and 69 right calcaneal fractures. According to the surgical approach, the patients were divided into the tarsal sinus approach group and the L-shaped incision approach group, 55 cases in each group. The L-shaped incision approach group was treated with traditional lateral L-shaped incision approach combined with internal fixation plate, while the sinus tarsal approach group was treated with tarsal sinus approach combined with Herbert screw and minimally invasive calcaneal locking plate. The operative time, intraoperative blood loss, length of hospital stay and time of fracture healing were recorded to evaluate the surgical effect. The B?hler angle, Gissane angle, calcaneal length and width of the patients before and after surgery were examined by X-ray and the surgical reduction was highly evaluated. Foot function recovery was evaluated by American Orthopedic Foot and Ankle Society (AOFAS) Maryland Scale, and postoperative complications were recorded. RESULTS: All patients were followed up to 12 months after surgery, the operation time and hospitalization time of patients in the sinus tarsal approach group were shorter than those in the L-shaped incision approach group (P<0.05), and the amount of intraoperative blood loss was lower than that in the L-shaped incision approach group(P<0.05). One year after surgery, B?hler angle, Gissane angle, calcaneus length and height were increased(P<0.05), calcaneus width was decreased (P<0.05). One year after the operation, the Maryland scores of the two groups were increased(P<0.05). During the follow-up period, the incidence of postoperative complications (incision infection, joint pain, soft tissue injury) in the sinus tarsalapproach group was lower than that in the L-shaped incision approach group(P<0.05). CONCLUSION The traditional lateral L-shaped incision approach and the tarsal sinus approach are both good for the treatment of SandersⅡand Ⅲ calcaneal fractures, but the latter can shorten the surgical treatment time and reduce the incidence of complications.

Objective: To investigate the clinical effects of lateral supramalleolar perforator island flaps with low rotation points in repairing foot skin and soft tissue defect wounds. Methods: The retrospective observational study was conducted. From October 2017 to August 2020, 14 patients (6 males and 8 females, aged 14-77 years) with foot skin and soft tissue defect wounds were admitted to Lanzhou University Second Hospital, including 4 cases of plantar skin tumor, 4 cases of chronic plantar ulcer, 4 cases of foot traffic injury, and 2 cases of residual wounds after deep foot burns. The wound size was 2.0 cm×2.0 cm to 7.0 cm×5.0 cm after tumor resection or debridement, which was repaired with island flap pedicled with the descending branch of the lateral supramalleolar perforator and the rotation point located at the lower front edge of the lateral ankle. The size of the flap ranged from 3.0 cm×2.0 cm to 8.0 cm×6.0 cm, and the length of vascular pedicle ranged from 8.0 to 14.0 cm. The flap was transferred by subcutaneous tunnel to repair the wound. The donor site wound of the flap was repaired with medium thickness skin graft from the lateral thigh. The survival of flaps, wound healing of the donor and recipient sites, and the occurrence of complications after operation were observed. The appearances of flaps and donor sites, and foot function were observed during follow-up. Results: The flaps of 14 patients survived successfully after operation, and the wounds in the donor and recipient sites healed well, without vascular crisis, venous congestion, or other complications. Follow-up for 2 to 24 months showed that the flaps had good appearance without bloating and were wear-resistant, the functions of wearing shoes and walking were not affected, and there was no obvious scar hyperplasia or hyperpigmentation at the donor site. Conclusions: With the descending branch of the lateral supramalleolar perforator as the pedicle and the rotation point located at the lower front edge of the lateral ankle, the island flap has a good effect in repairing the skin and soft tissue defect wound of the foot because of its reliable blood supply, simple design and operation, no need for vascular anastomosis, low rotation point, long vascular pedicle, and large radius of rotation.
