OBJECTIVE: To investigate the efficacy of minimally invasive osteotomy with preservation of blood supply to the transversely transported bone segment in the treatment of chronic ischemic lower limb diseases using tibial transverse bone transport. METHODS: A retrospective analysis was conducted on the clinical data of 12 patients with chronic ischemic lower limb diseases who met the selection criteria and were treated between June 2016 and December 2023. The cohort included 7 males and 5 females, aged 26-87 years (mean, 61.2 years). Among them, 7 patients had diabetic foot (DF), including 2 cases complicated by arteriosclerosis obliterans (ASO), with a DF duration ranging from 1.7 to 23.0 months (mean, 9.6 months) and ulcer sizes ranging from 3.2 cm×2.4 cm to 10.0 cm×6.6 cm. Three patients had ASO with a disease duration of 1.7-23.0 months (mean, 10.4 months) and ulcer or post-amputation wound sizes ranging from 2.2 cm×2.1 cm to 12.0 cm×7.7 cm. Additionally, 2 patients with thromboangiitis obliterans (TAO) had a disease duration of 7 and 12 months, respectively. Preoperatively, the mean foot skin temperature was (27.63±0.34)℃, and the visual analogue scale (VAS) score was 8.5±0.7. All patients underwent tibial transverse bone transport using minimally invasive osteotomy while preserving the blood supply to the transported bone segment. Postoperative complications and foot ulcer healing were observed. The effectiveness of tibial transverse bone transport was evaluated by comparing preoperative and postoperative foot skin temperature, VAS scores, as well as through CT angiography (CTA). RESULTS: One DF patient with ASO was lost to follow-up, while the remaining 11 patients were followed up 10-29 months (mean, 20.5 months). One DF patient had a displaced fracture at the site of tibial transport due to trauma, which healed after plaster immobilization; 1 DF patient had a small amount of pigmentation in the skin of the donor site, but the blood circulation was good; no complication such as pin tract infection, skin necrosis, or osteomyelitis occurred in the donor site of all patients. At 2-3 weeks postoperatively, the foot skin temperature was (34.21±0.65)℃, and the VAS score was 0.3±0.1, both significantly improved compared to preoperative ones ( t=-31.578, P<0.001; t=49.000, P<0.001). Two TAO patients experienced recurrent, persistent, intolerable pain at 7-10 days postoperatively, with no reduction in ulcer size or necrotic areas; 1 underwent toe amputation, and the other required a mid-leg amputation. The remaining patients achieved complete ulcer healing, with healing time ranging from 5.1 to 9.2 weeks (mean, 6.8 weeks). CTA showed no new vascular occlusions or embolisms. X-ray films at 4 months postoperatively demonstrated proper repositioning and good healing of the transported tibial bone segment. CONCLUSION The application of minimally invasive osteotomy with preserved blood supply to the transversely transported bone segment in tibial transverse bone transport for the treatment of chronic ischemic lower limb diseases effectively minimizes extensive soft tissue dissection, reduces surgical soft tissue damage, and better maintains local blood supply. This approach lowers the risk of postoperative infection and skin necrosis while accelerating postoperative recovery.

OBJECTIVE: To report the clinical experience of using Ilizarov wrist joint distraction technique in the treatment of a case of rheumatoid arthritis of the wrist. METHODS: In January 2019, a 49-year-old female patient with rheumatoid arthritis of the left wrist, complicated by ulnar impaction syndrome, was admitted for treatment. Preoperatively, the active range of motion of the left wrist was as follows: extension 0°-flexion 0°, pronation 65°-supination 35°, and grip strength of 4.0 kg. The visual analogue scale (VAS) score was 9, and the Cooney wrist function score was 15, indicating poor function. As conservative treatment failed to achieve symptom relief, Ilizarov wrist joint distraction surgery was performed. Postoperatively, joint distraction was applied at 2 mm increments on postoperative days 2 and 7, in 4 separate sessions. RESULTS: Postoperative X-ray film examination at 7 days revealed a distraction of 3.6 mm in the affected wrist joint compared to the contralateral side. The external fixator was removed 2.5 months postoperatively. At 22 months postoperatively, X-ray film and MRI examinations revealed that the joint space of the left wrist had returned to near-normal, with significant reduction in joint effusion and synovial proliferation. The active range of motion of the left wrist improved to extension 15°- flexion 30°, pronation 90°-supination 90°, with a grip strength of 18.0 kg. The wrist pain VAS score decreased to 0, and the Cooney wrist function score improved to 90, indicating excellent function. At 50 months postoperatively, follow-up X-ray film, MRI, and functional assessments showed the results similar to those at 22 months. CONCLUSION Ilizarov wrist joint distraction may be a viable treatment option for rheumatoid arthritis of the wrist.

OBJECTIVE: To explore the method and effectiveness of index finger proximal dorsal island flap supplied by the nutrient vessels of superficial branch of radial nerve for treatment of thumb skin and soft tissue defect. METHODS: Between August 2019 and December 2024, 12 patients with thumb skin and soft tissue defects caused by trauma accompanied by variation of the first dorsal metacarpal artery were treated. There were 8 males and 4 females, aged 19-55 years, with an average age of 32 years. The wound area ranged from 2.2 cm×2.0 cm to 5.5 cm×3.5 cm. The time from injury to operation ranged from 1.5 to 6.0 hours, with an average of 4.5 hours. After thorough debridement, the wound was repaired with a index finger proximal dorsal island flap supplied by the nutrient vessels of the superficial branch of the radial nerve. The flap area ranged from 2.4 cm×2.2 cm to 6.0 cm×4.0 cm. The donor site was repaired with free skin grafting. Regular follow-up was conducted postoperatively to observe the appearance, texture, sensory recovery of the flap, and the condition of the donor site. RESULTS: The operation time ranged from 30 to 72 minutes, with an average of 47 minutes; intraoperative blood loss ranged from 30 to 70 mL, with an average of 46 mL. After operation, partial necrosis occurred at the skin edge of the radial incision on the dorsum of the hand in 1 case, which healed after dressing changes; all other flaps survived uneventfully, with primary wound healing. The skin grafts at the donor sites all survived. All 12 patients were followed up 5-36 months, with an average of 14 months. The appearance and texture of the flaps were good. At last follow-up, the two-point discrimination of the flaps ranged from 4 to 9 mm, with an average of 5.2 mm. According to the functional evaluation criteria for upper limb issued by the Hand Surgery Society of Chinese Medical Association, the results were excellent in 11 cases and good in 1 case. No scar contracture, pain, or joint movement limitation was observed at the donor sites. CONCLUSION For patients with skin and soft tissue defects of the thumb accompanied by variation of the first dorsal metacarpal artery, the index finger proximal dorsal island flap supplied by the nutrient vessels of the superficial branch of the radial nerve can be selected. This method has advantages such as shorter operation time, less intraoperative bleeding, and good postoperative appearance and sensation of the flap.

Objective:To observe the anatomy of the recurrent branch of median nerve, summarize the injury mechanism of the recurrent branch of median nerve, and explore the surgical method and clinical effect of the compression.Methods:From February 2018 to October 2021, 12 fresh hand specimens were used in Department of Hand Surgery in the Second Hospital of Tangshan, including 6 male specimens, 3 left and 3 right hands, and 6 female specimens, 3 left and 3 right hands. Anatomy of the recurrent branch of median nerve and observation of its location, measurement of the length of each muscle branch innervating thenar muscle and the easy-to-jam position of the recurrent branch of median nerve in the course of running. The measurement results uses nonparametric test of statistical analysis by side and gender. P<0.05 was considered statistically significant. From January 2020 to January 2022, 21 patients with entrapment of the recurrent median nerve of wrist were treated, 14 males and 7 females. The age ranged from 31 to 65 years old, with an average of 46.2 years old. All patients developed thenar muscular atrophy. Before operation, the recurrent branch of median nerve was marked into the muscle point, and the thenar projection on palm surface was pressed, which caused fatigue and soreness. Electromyography examination: the motor latency of median nerve endings was more than 4.5 ms, and both fibrillation potential and positive potential appeared. The motor conduction velocity of all patients was less than 30 m/s, and the motor nerve amplitude was less than 10 mV. Surgical exploration of the recurrent branch of median nerve revealed that the trunk of the recurrent branch of median nerve made the tendon arch thickened at the starting point of the superficial head of flexor pollicis brevis, and there was compression between the deep layer of the palmar aponeurosis and the thenar musculocutaneous membrane, which was completely released during the operation to relieve the compression factor. All 21 patients had followed-up in outpatient. Results:Distance from the origin of the recurrent branch of median nerve to the distal edge of transverse carpal ligament. The distance from the origin of the recurrent branch of median nerve to the distal edge of transverse carpal ligament were (0.30, 0.31, 0.32) cm and (0.31, 0.32, 0.32) cm in male left and right groups, respectively, with no statistical significance ( Z=-0.943, P=0.346); The female left and right groups were (0.28, 0.28, 0.28) cm and (0.29, 0.30, 0.30) cm, respectively, and the difference was statistically significant ( Z=-2.121, P=0.034). The length and transverse diameter of the trunk of the recurrent branch of the median nerve, the length of the superficial head branch of flexor pollicis brevis and the length of the palmar muscle branch of the thumb had no significant difference between the left and right sides of males and females( P > 0.05). The length of abductor pollicis brevis muscle branch: the male left and right groups were (1.45, 1.27, 1.31) cm and (1.54, 1.38, 1.47) cm, respectively, and there was no statistical difference ( Z=-1.528, P = 0.127); The female left and right groups were (1.21, 1.18, 1.15) cm and (1.25, 1.24, 1.25) cm respectively, and the difference was statistically significant ( Z=-1.993, P=0.046). All the 21 patients were entered in follow-up for 9-24 (average 15) months. After operation, the wounds of all patients healed in the first stage, the soreness at thenar disappeared, and the thenar muscle was full in appearance. In 21 patients, the thumb abduction function returned to normal, the thumb to palm opposition returned to normal in 19 cases, and was slightly limited in 2 cases. After operation, thenar muscle strength recovered to grade 5 in 19 cases and grade 4 in 2 cases. At the last follow-up, electromyography showed that the motor latency of median nerve endings was less than 4.5 ms, and the motor conduction velocity was greater than 40 m/s; Motor nerve amplitudes were all greater than 10 mV. According to the functional evaluation standard of carpal tunnel syndrome recommended by Gu Yudong, 19 cases were excellent, 2 cases were good, and the excellent and good rate was 100%. Conclusion:The length of each nerve branch of the recurrent median nerve innervates thenar muscle is different, and there are many factors that cause the recurrent median nerve to get stuck. It is of high clinical value to master the anatomical structure of the recurrent median nerve and the mechanism of the entrapment, and to completely loosen vulnerable parts by surgery.

OBJECTIVE: To summarize the effectiveness of Kirschner wire buckling combined with bone fixation in the treatment of metacarpal avulsion fracture. METHODS: The clinical data of 35 patients of metacarpal avulsion fracture admitted between March 2017 and June 2022 were retrospectively analyzed. There were 22 males and 13 females; the age ranged from 20 to 55 years, with an average of 31.6 years. There were 17 cases of the second metacarpal avulsion fracture, 6 cases of the fourth metacarpal avulsion fracture, and 12 cases of the fifth metacarpal avulsion fracture. The causes of injury included 21 cases of strangulation, 8 cases of sprain, and 6 cases of sports injury. X-ray film examination showed that the size of the avulsion fracture of metacarpal bone ranged from 0.30 cm×0.20 cm to 0.55 cm×0.45 cm. The total active motion (TAM) of the injured finger before operation was (154.00±17.38)°. The time from injury to operation was 3-10 days, with an average of 5.8 days. Follow-up regularly after operation, X-ray film and CT examination were performed to evaluate fracture healing and TAM of injured finger was measured. The finger function was evaluated by the trial standard of upper limb function evaluation of Hand Surgery Society of Chinese Medical Association. RESULTS: All the incisions healed by first intention. All 35 patients were followed up 9-36 months, with an average of 28 months. All metacarpal avulsion fractures achieved bony healing, and the healing time was 4-6 weeks, with an average of 4.8 weeks. The metacarpophalangeal joint of the patient was stable, without stiffness, and the flexion and extension activities were good. At last follow-up, the TAM of the injured finger reached (261.88±6.23)°, which was significantly different from that before operation ( t=-35.351, P<0.001). The finger function was evaluated according to the trial standard of upper limb function evaluation of the Society of Hand Surgery of Chinese Medical Association, and 33 cases were excellent and 2 cases were good, with an excellent and good rate of 100%. CONCLUSION The treatment of metacarpal avulsion fracture with Kirschner wire buckling combined with bone fixation has the advantages of less trauma, firm fixation, and less interference to the soft tissue around metacarpophalangeal joints, which is a good alternative method for the metacarpal avulsion fracture.

Objective:To explore the correlation of serum cystatin C (CysC), serum and glucocorticoid-regulated kinase 1 (SGK1) and homocysteine ??(Hcy) with postoperative lymph node metastasis in patients with lung cancer and their predictive values.Methods:One hundred and thirty-one patients with stage Ⅰ-Ⅲ A non-small cell lung cancer (NSCLC) who underwent tumor resection and systematic lymph node dissection in Meishan Hospital of Traditional Chinese Medicine from November 2016 to June 2018 were prospectively selected. Patients received a 3-year follow-up after surgery, and were classified into metastasis group (42 cases) and non-metastasis group (89 cases) according to the presence or absence of lymph node metastasis during the follow-up period. Serum CysC, SGK1 and Hcy levels were detected at the 1st day after surgery, and the levels of the three indicators were compared among patients with different TNM stages, differentiation degrees and histological types. Meantime, the clinicopathological characteristics and levels of the three indicators were also compared between metastasis group and non-metastasis group. Spearman analysis was conducted to discuss the correlation between the three indicators and clinicopathological characteristics of patients. Multivariate logistic regression analysis was performed to screen the factors affecting postoperative lymph node metastasis (the median levels of CysC, SGK1 and Hcy were used as the cut-off values, > the median level was a high level). Taking the pathological examination results as the gold standard, receiver operating characteristic (ROC) curve was applied to evaluate the predictive value of level of the three indicators alone or in combination for postoperative lymph node metastasis. Results:The serum levels of CysC, SGK1 and Hcy in patients with TNM stage Ⅲ A were higher than those in patients with stageⅠ-Ⅱ; the serum levels of CysC, SGK1 and Hcy in patients with poorly differentiated tumors were higher than those in patients with medium and well-differentiated tumors; the serum levels of CysC, SGK1 and Hcy in patients with non-squamous cell carcinoma were higher than those in patients with squamous cell carcinoma; the differences were statistically significant (all P < 0.05). Spearman correlation analysis showed that serum CysC, SGK1 and Hcy levels were correlated with TNM stage ( r values were 0.454, 0.672 and 0.645), differentiation degree ( r values were -0.399, -0.403 and -0.451), histological type ( r values were 0.528, 0.760 and 0.611) (all P < 0.001). Compared with non-metastasis group, an elevation was found in serum levels of CysC, SGK1 and Hcy in metastasis group [(1.37±0.30) mg/L vs. (1.16±0.25) mg/L, (53±4) pg/ml vs. (41±3) pg/ml, (18.3±2.3) mol/L vs. (15.4±1.8) mol/L] (all P < 0.001). Multivariate logistic regression analysis showed that TNM stage Ⅲ A ( OR = 2.944, 95% CI 1.556-6.847, P = 0.004) and high level of CysC (> 1.23 mg/L, OR = 2.431, 95% CI 1.402-5.226, P = 0.008), high level of SGK1 (>50 pg/ml, OR = 4.010, 95% CI 1.815-11.748, P = 0.004), high level of Hcy (> 16.8 μmol/L, OR = 3.742, 95% CI 1.747-9.142, P = 0.001) were independent risk factors for postoperative lymph node metastasis. ROC curve analysis showed that for predicting postoperative lymph node metastasis, the area under the curve (AUC) of serum CysC, SGK1 or Hcy level alone was 0.769, 0.808 and 0.816, the AUC of CysC+Hcy, CysC+SGK1 and Hcy+SGK1 was 0.889, 0.890 and 0.910, and the AUC of the three indicators was 0.936. Conclusions:Levels of serum CysC, SGK1 and Hcy in NSCLC patients with postoperative metastasis are higher than those in patients without metastasis, and the levels of the three are positively correlated with the TNM stage and histological type, and negatively correlated with the differentiation degree. The combined detection of the three has good predictive value for postoperative lymph node metastases in NSCLC patients.

Objective:To investigate the method and outcome of reconstruction of thumb soft tissue defect by index finger proximal dorsal island flap supplied by the second dorsal metacarpal artery (SDMA).Methods:From August, 2015 to December, 2017, 12 cases of thumb soft tissue defect were treated by index finger proximal dorsal island flap supplied by SDMA. The site of defect ranged from 2.0 cm×2.4 cm to 5.5 cm×3.0 cm, and the flap area ranged from 2.2 cm×2.6 cm to 6.0 cm×3.3 cm. The donor site was repaired by split-thickness skin graft from the forearm of the injured limb. All patients received regular outpatient follow-up after surgery. The appearance, texture, sensory recovery and donor site of the flap were observed.Results:All the 12 flaps had 5-16 (8.8 in average) months follow-up and survived, the donor site and wounds healed in primary stage. The appearance, sensory and function of the flaps were good. There were no scar contracture on the donor sites, and no pain and limitation of motion in the joints. At the last follow-up, according to the Criteria for Function Assessment of Upper Limbs by the Branch of Hand Surgery of Chinese Medicine Association, the thumb functions were excellent in 11 cases and good in 1 case.Conclusion:Index finger proximal dorsal island flap supplied by SDMA is easy to operate, and has constant blood supply, improved rotation angle of the flap vessel base. It is a good method to repair the soft tissue defect of thumb.

Objective: To explore the effectiveness of hollow screw for the treatment of basilar part fracture of hamate hook. Methods: Five patients with basilar part fracture of hamate hook, aged 24-47 years (mean, 31 years) were treated with open reduction and hollow screw fixation between June 2015 and February 2019. There were 4 males and 1 female. The causes of injury were athletic injury in 3 cases, falling injury in 1 case, and crushing injury in 1 case. Among them, 1 case was combined with sensory disturbance of one and a half fingers on the ulnar side of the palm. The grip strength of the affected side was significantly decreased when compared with that of the healthy side in all patients. The intervals between injury and surgery were 3-8 days (mean, 4.2 days). Postoperative follow-up was conducted regularly to measure the grip strength of the affected and healthy fingers and the total motion of ring and little fingers of the affected side. Darrow criteria was used to evaluate the effectiveness. Results: All the incisions healed by primary intention. All the patients were followed up 6-32 months (mean, 16 months). X-ray films showed that the basilar part fracture of hamate hook reached bony union, and the healing time was 2.0-3.5 months (mean, 2.2 months). At last follow-up, the grip strength of the affected side was (35.80±3.76) kg, showing no significant difference when compared with healthy side [(36.00±4.94) kg] ( t=0.094, P=0.930); and the total motion of ring and little fingers of the affected side was (529.0±8.9)°, which was significantly different from that before operation [(232.0±34.7)°] ( t=18.108, P=0.000). In 1 patient with ulnar nerve injury, the two-point discrimination of the innervation area was 4 mm, and the pain sensation and temperature sensation returned to normal. Assessed by Darrow criteria, the results were excellent in 4 cases and good in 1 case. Conclusion: For the basilar part fracture of hamate hook, hollow screw fixation can obtain secure reduction and fixation and provide sustained compression and counter-rotation for the broken end of fracture, thus allowing early joint motion and promoting fracture healing and recovery of wrist function. It is a relatively good method for the treatment of basilar part fracture of hamate hook.

Objective: To investigate the effectiveness of ipsilateral digital proper artery dorsal branch flap to repair mid-phalanx degloving injury with distal segment finger defect. Methods: Between February 2013 and July 2016, 11 cases (11 fingers) of mid-phalanx degloving injury with distal segment finger defect were treated. There were 9 males and 2 females with an average age of 33.6 years (range, 18-59 years). The injury caused by twisting in 8 cases and crushing in 3 cases. The injury located at index finger in 3 cases, middle finger in 6 cases, and ring finger in 2 cases. The skin avulsion was from proximal interphalangeal joint in 1 case, proximal 1/4 of mid-phalanx in 6 cases, and 1/2 of mid-phalanx in 4 cases. The area of wounds ranged from 4.0 cm×1.7 cm to 6.2 cm×2.6 cm. The interval between injury and operation was 2.5-6.0 hours (mean, 4.5 hours). All defects were repaired with the ipsilateral digital proper artery dorsal branch flaps. The size of flaps ranged from 4.4 cm×1.9 cm to 7.0 cm×2.9 cm. Nerve anastomose was carried between digital proper nerve dorsal branch in the flap and digital proper nerve stump in the wound. The donor sites were repaired by skin grafting. Results: Tension blisters of the flap and partial necrosis occurred in 1 case, and healed after dressing change. The other flaps and skin grafting survived, and wounds healed by first intention. All patients were followed up 6-18 months (mean, 16 months). The texture and appearance of all the flaps were satisfactory. At 6 months after operation, two-point discrimination of flaps ranged from 7 to 10 mm (mean, 8.5 mm). At last follow-up, according to the functional assessment criteria of upper limbs by the Branch of Hand Surgery of Chinese Medicine Association, the results were excellent in 10 cases and good in 1 case, with the excellent and good rate of 100%. Conclusion: The ipsilateral digital proper artery dorsal branch flap is a good method to repair mid-phalanx degloving injury with distal segment finger defect for the advantages of simple operation, less damage in donor site, high survival rate of the flap, and good feeling recovery of the finger.
