OBJECTIVE: To investigate the effectiveness of free palmaris longus tendon graft reconstruction in the treatment of gouty tophus erosion lesions in flexor tendon of wrist and hand. METHODS: A retrospective analysis was conducted on 8 patients with gouty tophus erosion lesions in flexor tendon of wrist and hand who underwent free palmaris longus tendon graft reconstruction between June 2017 and December 2023. All patients were male, aged 22-65 years, with an average of 45.9 years. The duration of gout history ranged from 2 to 18 years, with an average of 8.8 years. The duration from the discovery of gouty tophus to operation ranged from 12 to 26 months, with an average of 17.6 months. The gouty tophus eroded the flexor pollicis longus tendon in 4 cases, with Verdan flexor tendon zones being Ⅰ-Ⅱ in 1 case and Ⅳ-Ⅴ in 3 cases. The flexor digitorum profundus tendons were affected in 2 cases for the index finger, 1 for the middle finger, and 1 for the ring finger, all located in zone Ⅳ-Ⅴ. The long axis of the gouty tophus ranged from 2.3 to 4.5 cm, with an average of 3.4 cm. All 8 patients presented with limited finger flexion and extension. Among them, 4 cases were accompanied by median nerve compression symptoms, and 1 case had associated bone and joint destruction in the hand. The total active motion (TAM) of the affected finger was (81.3±30.2)° before operation according to the hand function evaluation criteria for tendon repair by the Chinese Society of Hand Surgery of the Chinese Medical Association, and the functional evaluation was poor. The harvested palmaris longus tendon intraoperatively was 7-9 cm in length. RESULTS: Surgical incisions in all 8 patients healed by first intention, with no infections, graft non-union, or significant adhesion complications. All patients were followed up 8-25 months, with an average of 14.8 months. Numbness symptoms resolved in all 4 patients who presented with median nerve compression symptoms. Patients did not experience wrist pain or other discomfort, and function was not compromised. At last follow-up, according to the hand function evaluation criteria for tendon repair by the Chinese Society of Hand Surgery of the Chinese Medical Association, the TAM of 8 patients was (197.5±55.8)°, which significantly improved when compared with that before operation ( t=11.638, P<0.001); the hand function of 1 patient with gouty tophus in zone Ⅰ-Ⅱ flexor pollicis longus tendon was good, and the other 7 patients were excellent. CONCLUSION Free palmaris longus tendon graft reconstruction demonstrates good effectiveness in treating gouty tophus erosion lesions in flexor tendon of wrist and hand.

OBJECTIVE: To explore the effectiveness of multi-segment inverted Y-shaped vein transplantation using the anterior lateral malleolar venous network for repair of amputated palm injury distal to the superficial palmar arch. METHODS: Between September 2018 and July 2023, 5 patients with amputated palm injury distal to the superficial palmar arch were treated. There were 3 males and 2 females with an average age of 35.4 years (range, 29-52 years). The time from injury to admission was 1-6 hours (mean, 3.2 hours). The multi-segment inverted Y-shaped vein transplantation in the anterior lateral malleolar venous network were used to repair the common and proper palmar digital arteries; the another anterior lateral malleolar venous network was used to repair the dorsal vein of the hand. The soft tissue defect of dorsal hand in 1 patient was repaired with the pedicled ilioinguinal flap, and the wound at the donor site was directly sutured. Postoperative treatment included anti-infection therapy, antispasmodic therapy, and thrombosis prevention measures. RESULTS: The partial necrosis of the fingertip of the thumb occurred in 1 case, and the marginal necrosis of the abdominal flap after operation occurred in 1 case. The remaining fingers showed good blood supply with normal tension. The incision at donor site of the abdominal flap healed by first intention. All patients were followed up 8-41 months (median, 19 months). At last follow-up, the hand contour was satisfactory; the grasping function, opposition function, and proprioception recovered, and two-point discrimination ranged from 5 to 7 mm (mean, 6 mm). According to the upper extremity function evaluation criteria issued by Hand Surgery Society of the Chinese Medical Association, the functional outcomes were excellent in 3 cases, good in 1 case, and fair in 1 case. CONCLUSION The multi-segment inverted Y-shaped vein transplantation using the anterior lateral malleolar venous network for repairing defects in the common and proper palmar digital arteries distal to the superficial palmar arch offers advantages such as superficial location, flexible harvesting, and high compatibility. This technique has demonstrated favorable outcomes in complex transmetacarpal amputation reconstruction.

OBJECTIVE: To investigate the clinical effect of minimally invasive technique in the treatment of moderate and severe gluteal muscle contracture. METHODS: A retrospective study was conducted on 85 patients (170 sides) with bilateral gluteal muscle contracture admitted from January 2016 to December 2019. All patients were treated with minimally invasive release of tendon knife. There were 32 males and 53 females, ranging in age from 15 to 37 years old, with an average age of (22.3±6.3) years old. Operation time, intraoperative blood loss, incision length, first postoperative ambulation time, complication rate, recurrence rate, and Harris hip score (HHS) were analyzed and evaluated. RESULTS: The average follow-up time was (16.2±4.6) months, ranging from 12 to 30 months. The operation time ranged from 7 to 15 min, with an average of (10.2±3.1) min. Intraoperative blood loss ranged from 2 to 20 ml, with an average of (8.4±2.2) ml. The incision length ranged from 0.6 to 2.0 cm, with an average of (0.8±0.3) cm. The time to postoperative ambulation ranged from 12 to 28 h, with an average of (20.0±3.2) h. All patients achieved primary wound healing without sciatic nerve injury or recurrence. HHS hip function scores ranged from 90 to 98, with an average score of (96.2±1.4). Complications included intraoperative tendon blade tip fracture in two cases (removed under fluoroscopic guidance) and subcutaneous hematoma in three cases-two resolved with compression and one with open evacuation.. Twenty-nine patients exhibited transient swaying gait postoperatively, of which 24 patients returned to normal after 4 weeks and 5 patients returned to normal after 6 weeks. CONCLUSION Minimally invasive tendon blade release is a safe and effective technique for treating gluteal muscle contracture, offering minimal trauma, rapid recovery, and excellent cosmetic and functional outcomes. However, it exhibits a low risk of blade tip fracture and sciatic nerve injury, warranting experienced surgical handling.

OBJECTIVE: To evaluate the clinical effect and safety of acupuncture manipulation on treatment of intractable facial paralysis (IFP), and verify the practicality and precision of the Anzhong Facial Paralysis Precision Scale (Eyelid Closure Grading Scale, AFPPS-ECGS). METHODS: A multicentre, single-blind, randomized controlled trial was conducted from October 2022 to June 2024. Eighty-nine IFP participants were randomly assigned to an ordinary acupuncture group (OAG, 45 cases) and a characteristic acupuncture group (CAG, 44 cases) using a random number table method. The main acupoints selected included Yangbai (GB 14), Quanliao (SI 18), Yingxiang (LI 20), Shuigou (GV 26), Dicang (ST 4), Chengjiang (CV 24), Taiyang (EX-HN 5), Jiache (ST 6), Fengchi (GB 20), and Hegu (LI 4). The OAG patients received ordinary acupuncture manipulation, while the CAG received characteristic acupuncture manipulation. Both groups received acupuncture treatment 3 times a week, with 10 times per course, lasting for 10 weeks. Facial recovery was assessed at baseline and after the 1st, 2nd and 3rd treatment course by AFPPS-ECGS and the House-Brackmann (H-B) Grading Scale. Infrared thermography technology was used to observe the temperature difference between healthy and affected sides in various facial regions. Adverse events and laboratory test abnormalities were recorded. The correlation between the scores of the two scales was analyzed using Pearson correlation coefficient. RESULTS: After the 2nd treatment course, the two groups showed statistically significant differences in AFPPS-ECGS scores (P<0.05), with even greater significance after the 3rd course (P<0.01). Similarly, H-B Grading Scale scores demonstrated significant differences between groups following the 3rd treatment course (P<0.05). Regarding temperature measurements, significant differences in temperatures of frontal and ocular areas were observed after the 2nd course (P<0.05), becoming more pronounced after the 3rd course (P<0.01). Additionally, mouth corner temperature differences reached statistical significance by the 3rd course (P<0.05). No safety-related incidents were observed during the study. Correlation analysis revealed that the AFPPS-ECGS and the H-B Grading Scale were strongly correlated (r=0.86, 0.91, 0.93, and 0.91 at baseline, and after 1st, 2nd, and 3rd treatment course, respectively, all P<0.01). CONCLUSIONS Acupuncture is an effective treatment for IFP, and the characteristic acupuncture manipulation enhances the therapeutic effect. The use of the AFPPS-ECGS can more accurately reflect the recovery status of patients with IFP. (Trial registration No. ChiCTR2200065442).

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective:To investigate the relationship between sagittal position parameters and screw loosening after unilateral biportal endoscopic (UBE) combined with percutaneous pedicle screw fixation for single-segment lumbar spinal stenosis.Methods:A total of 180 patients with single-level lumbar spinal stenosis who received UBE combined with percutaneous pedicle screw internal fixation in our hospital from June 2020 to June 2023 were enrolled. According to the postoperative follow-up, they were divided into the non-loosening group (112 cases) and the loosening group (68 cases). The demographics, operative parameters and sagittal position [pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), thoracic kyphosis (TK), sagittal vertical axis (SVA)] before and after operation were compared between the two groups. The indicators with significant differences between the two groups were included in the multivariate logistic regression analysis to analyze the influencing factors of screw loosening. The dose-response relationship between sagittal position parameters and screw loosening was analyzed by restricted cubic spline model.Results:At 6 months and 1 year postoperatively, the fusion rates in the loosening group were 47.1% and 55.9%, respectively, which were significantly lower than the rates (85.7% and 100.0%) in the non-loosening group, respectively ( P<0.05). Postoperatively, the SS in the non-loosening group (36.16°±5.35°) and the loosening group (32.02°±5.54°) and the LL in the loosening group (51.26°±6.35°) were all significantly lower than preoperative values (40.51°±6.11°, 40.49°±6.08°, and 54.08°±6.21°) ( P<0.05). Meanwhile, the PT in the non-loosening group (15.24°±2.69°), TK in the non-loosening group (32.46°±7.29°), PI in the loosening group (56.82°±5.23°), PT in the loosening group (17.01°±3.64°), and TK in the loosening group (34.87°±7.21°) were all significantly higher than preoperative values (13.12°±3.19°, 30.25°±5.17°, 52.84°±5.12°, 13.15°±3.21°, and 30.26°±5.12°) ( P<0.05). Postoperatively, the loosening group had significantly lower SS (32.02°±5.54°), LL (51.26°±6.35°), and SVA (-0.87±1.06 cm) than the non-loosening group (36.16°±5.35°, 53.73°±6.27°, and -0.51±1.04 cm), respectively ( P<0.05). Conversely, the PI (56.82°±5.23°), PT (17.01°±3.64°), and TK (34.87°±7.21°) in the loosening group were significantly higher than those in the non-loosening group (53.48°±5.20°, 15.24°±2.69°, and 32.46°±7.29°), respectively ( P<0.05). Binary logistic regression analysis indicated that PT, SS, LL, and SVA were independent risk factors for screw loosening ( P<0.05). The restricted cubic spline model revealed a nonlinear dose-response relationship between sagittal parameters (PT, SS, LL, and SVA) and screw loosening ( P<0.05). With increasing PT, the odds ratio (OR) for screw loosening increased, whereas increasing SS, LL, and SVA reduced the OR for screw loosening. Conclusion:After UBE combined with percutaneous pedicle screw fixation in single-level lumbar spinal stenosis patients, sagittal position parameters PT were positively correlated with screw loosening, while SS, LL and SVA were negatively correlated with screw loosening.
