ObjectiveTo explore the clinical effectiveness and safety of stick-point sinew-soothing and bone-setting manipulation for scapulohumeral periarthritis. MethodsUsing prospective randomised controlled trial method， 60 cases of patients with scapulohumeral periarthritis were collected and randomly divided into 30 cases each in control group and trial group. Both groups of patients were orally treated with celecoxib， on the basis of which the control group was treated with traditional bonesetting manipulation once every other day for 14 days， while the trial group was treated with stick-point sinew-soothing and bone-setting manipulation once every 3~5 days for 14 days. Both groups were treated for 2 courses. The main observation indexes were pain visual analogue scale （VAS） score and shoulder pain and dysfunction index （SPADI）， which were evaluated once before treatment and after 2 and 4 weeks of treatment. The secondary effectiveness indicators included the university of California at Los Angeles shoulder rating scale （UCLA）， traditional Chinese medicine syndrome score （including symptom scores as joint pain， pain in a fixed place， activity limitation， local stiffness）， and serum interleukin （IL-6） and tumour necrosis factor α （TNF-α） levels before and after the treatment， in order to evaluate the clinical effectiveness， and to record the adverse reactions that occurred in the process of diagnosis and treatment. ResultsCompared with the groups before treatment， the pain VAS score， SPADI and scores of joint pain， pain with a fixed place， activity limitation and local stiffness were lower， UCLA score was higher， and serum IL-6 and TNF-α levels were lower at 4 weeks of treatment in the two groups （P＜0.05）. When comparing the two groups between the groups at 2 and 4 weeks of treatment， the pain VAS score， SPADI and TCM scores of each symptom in the study group were lower than those in the control group， the UCLA score was higher than those in the control group （P＜0.01）， and the serum IL-6 and TNF-α levels were lower than those in the control group at 4 weeks of treatment （P＜0.01）. The clinical effectiveness rate of the study group was 66.67%， which was significantly higher than that of the control group， which was 40.00% （P = 0.038）. No adverse reactions were seen in both groups during the study. ConclusionCompared with the traditional massage manipulation， the treatment of scapulohumeral periarthritis with stick-point sinew-soothing and bone-setting manipulation has more advantages in relieving pain symptoms， reducing inflammatory reaction， and promoting the recovery of shoulder joint function.

【Objective】 To explore the emergency treatment of penoscrotal avulsion injury based on the American Association for Surgery and Trauma (AAST) penoscrotal injury grade. 【Methods】 Data of 30 patients with penoscrotal avulsion injury treated in our hospital with in-situ suture, skin grafting or skin flap during Oct.2003 and Dec.2017 were reviewed. 【Results】 Among the 30 patients, 29 received emergency surgery, including in-situ suturein 15 grade Ⅰ-Ⅲ cases, skin graft in 8 grade Ⅳ-Ⅴ cases, and skin flap in 6 cases;1 case received delayed operation due to wound infection on admission. In the perioperative period,25 cases had more than 90% wound healing, 3 cases had 70% wound healing after wound dressing change, and 2 cases had complete necrosis. Second-stage skin graft yielded satisfactory penoscrotal appearance. 【Conclusion】 According to the specific conditions of patients, reasonable surgical methods can be selected. For grade Ⅰ-Ⅲ patients, in-situ suture can be used, while for grade Ⅳ-Ⅴ patients, wound condition, age, fertility and other factors should be taken into consideration so as to preserve the function of testis to the maximum extent.

Objective:To explore the feasibility and clinical effect of emergency lateral thigh muscle transfer in functional reconstruction of major traumatic muscle defects.Methods:Emergency surgeries for 8 patients(7 males and 1 female) with muscle defects were carried out subject to emergently reconstruct the power of lateral femoral muscle superficial region, between March 2020 and December 2021, in the Department of Hand and Foot Microsurgery Hospital, Xi'an Fengcheng Hospital. The 8 patients were 23 to 52 years old with an average of 37.6 years old. Five patients injured by machine crush, 2 by heavy object crush and 1 by traffic accident. Five patients were in Gustilo III B injury in forearm, including 2 with flexor muscle group defects, 2 with extensor muscle group defects and 1 with defect of dorsal metacarpal flexor muscle and extensor muscle. Among the 5 patients, 2 patients had the defects in left forearm and 3 in right forearm. One patient had defect of right 1st metacarpal bone and skin and thenar muscle. One patient suffered a complete right upper arm detachment with musculocutaneous nerve being drawn out from the bicipital muscle. One patient had Gustilo III C injury in the right calf with defects of extensor hallucis longus and extensor digitorum. The areas of soft tissue defect were 10.0 cm×8.0 cm-36.0 cm×11.0 cm and the size of flaps was 12.0 cm×6.0 cm-38.0 cm×12.0 cm with the volumes of excised muscle at 18.0 cm×9.0 cm×1.5 cm-10.0 cm×2.0 cm×1.0 cm. The anatomical cross-section and length of the corresponding muscle on the healthy side were measured by musculoskeletal ultrasound. The chimeric tissue flap was designed on the anterolateral side of the thigh. The flap was designed according to the size of the wound and the corresponding flap. Then 1 or 2 muscle tissue blocks were designed and cut from the superficial region of the lateral femoral muscle according to the condition of the muscle defect, to cover the wound and reconstruct the muscle power. Postoperative follow-ups were conducted by scheduled hospital visit. The contents of follow-up included dynamic observation, evaluation and record through musculoskeletal ultrasound, electromyography and strength of muscle.Results:For the 8 patients who were subject to a muscle reconstruction, the transferred muscles and flaps survived in stage-one without vascular event. Postoperative follow-ups lasted for 10 to 32 months with an average of 19.6 months. The strength of muscle was evaluated according to the M 4 strength of muscle. Strength of muscle restored to M 4 or above in 7 patients who could lift, hook or push a heavy object in 5-30 kg of weight, with free joint movement. One patient restored the strength of muscle to M 3+. Muscle contraction was detected 2-4 months after surgery by musculoskeletal B ultrasound. The average ratio of contraction to resting cross sectional area in 5 cases was 1.45±0.42. The shape of limb was bilaterally symmetrical. There was no discomfort in the donor site and knee joint. The flaps were soft and glossy, with protective sensation restored. Conclusion:Muscle transfer from the lateral femoral muscle superficial region in emergency surgery for functional reconstruction of traumatic muscle defects is feasible and effective with a good clinical effect.

Objective:To discuss outcomes of emergency repairing for Gustilo III B and III C fractures of forearm with complicated tissue defects and the related influence factors.Methods:From January 2014 to Feburary 2022, data of 98 cases of Gustilo III B and III C fractures with large compound defects of soft tissue, blood vessel, bone, tendon or muscle from elbow to wrist were collected. Primary debridement, bone fixation, wound coverage by free flap, bone transfer(or bone cement filling) or dynamic reconstruction of muscle were completed with emergency surgery in Department of Hand and Foot Microsurgery, Xi'an Fengcheng Hospital. Postoperative follow-ups were conducted through outpatient clinic visits, telephone and WeChat reviews. Video clips, questionnaires and the latest information of patients were also analysed. Rank sum test and Chi-square test were used to examine the relationship between independent variables such as general condition, disease condition and surgical procedures of chimeric tissue transfer group and simple flap transfer group, together with dependent variables such as limb salvage, number of surgery, wound healing, function scores, and complications. P<0.05 were further included in the regression equation to discover the relationship between multiple independent variables and dependent variables. Results:Follow-up lasted for 6-96 months, with an average of 71.1 months. In the chimeric group, the limb salvage rate was at 95.1%, with an infection rate of 8.50% and an average number of surgery was 2.13±0.89. In the simple flap transfer group, the limb salvage rate was at 87.5%, with an infection rate of 15.38% and an average number of surgery was 2.62±0.64. The good rate of Anderson score was 65.3% and the average score of Disability of the Arm, Shoulder and Hand(DASH) was 32.9(0-60) points for all the patients. There were significant differences in dependent variables of limb salvage and infection rate between the 2 groups ( P<0.05). Ischemia time and method of bone fixation led to significant differences in number of surgery ( P<0.05). Methods of bone fixation and the types of flap made significant differences in wound healing ( P<0.05). Underlying disease, bonedefect, Gustilo classification and method of bone fixation all contributed to the significant differences in function score ( P<0.05 or P<0.01) . Conclusion:Emergency surgery for repair of serious injury of forearm has a relatively high limb salvage rate and good functional effects. The limb salvage rate is not correlated with independent variables such as severity of injury, Mangledextremity Severity Score (MESS) and ischemia time, while transfer of a simple flap or a chimeric flap is significantly correlated with the limb salvage rate, infection and wound healing. The severity of injury, ischemia time and bone defect are correlated with functional assessment, number of surgery and bone healing.

Objective:To explore the feasibility in reconstruction of the muscular power with the superficial part of lateral femoral muscle through anatomical study on the superficial region of lateral femoral muscle.Methods:Studies on 4 sides of lower limbs of 2 cadaver specimen were conducted in the Department of Hand and Foot Microsurgery of Xi'an Fengcheng Hospital. Intraoperative observations and measurements were further carried out on 21 sides of 21 patients. Muscular fascia in superficial region, muscular gross morphology, thickness, length and width of muscles, length of muscle fibres and pinnate angles of muscle surface were observed and measured. Both blood vessels and nerves in the muscle were separated to measured.Results:The superficial region of lateral femoral muscle was in a shape of fusiform and started from the greater trochanter and ended at the patella and rectus femoris, with the fascia at proximal end and the muscle of distal end. The inferior muscle fibres of the fascia were arranged in sequence and ended at the deep fascia from proximal to distal. Mean muscle thickness was measured at 1.96 cm±0.48 cm, and mean pinnate angle was of 18.9°±3.3°. The superficial region was found being distributed by the descending branches of lateral circumflex femoral artery(LCFA) and the second branch of femoral nerve, and they accompanied each other. At 5.0 cm from the point of entry to the muscle, the diameter of the vessels was measured at 2.39 mm±0.52 mm, and the diameter of nerves was at 2.64 mm±0.61 mm. Both of arteries and nerves further branched out anteriorly and posteriorly in 1.0-1.5 cm intervals after having entered the muscle. At 0 - 2.5 cm away from the muscle entry point, a larger branch was often running posteriorly into the muscle, and this branch appears on all 4-sided specimens. While the occurrence rate in the 21 sides of patients observed in operations was of 90.5%, with a transverse diameter at 1.23 mm±0.28 mm.Conclusion:The superficial region of lateral femoral muscle is dominated by independent vessels and nerves and there are many branches from superior vessels and nerves, which form an anatomical basis for one or more muscular flaps.

Objective:To explore the feasibility of functional reconstruction of muscle power in treatment of traumatic muscle defects by transferring part of superficial vastus of lateral thigh.Methods:From March 2020 to March 2023, reconstruction of muscle power with transfer of superficial lateral thigh muscle was performed on 9 patients in the Department of Hand and Foot Microsurgery of Xi'an Fengcheng Hospital. Nine patients were assigned in a study group. A total of 48 patients who previously had the surgery of chimerically grafted superficial vastus of lateral thigh were recruited as the "previous surgery group" and another group of 71 staff volunteers from our hospital were recruited as the "healthy control group". Of the study group, 5 patients had Gustilo type ⅢB injury in forearm (two with defects of flexor muscle group and 3 with extensor muscle group, 2 with the defects in the left and 3 in the right), one had defect of both flexor and extensor muscle groups in dorsal hand, one had defect of right 1st metacarpal with defects of soft tissue and thenar muscle, one had a completely severed right upper arm with a withdrawn musculocutaneous nerve from the biceps brachii and one had Gustilo ⅢC injury in right calf with defects of tibialis anterior, extensor longus and extensor phalangeal muscle. In the emergency surgery, part of the superficial muscles of lateral thigh were taken to reconstruct the muscular power for the defected traumatic muscles. During the surgery, the excessed nerve with a length of 3.0 cm proximally was removed at 3.0 cm from the point where the nerve entered the muscle. In the transfer of superficial chimeric muscle of lateral thigh, a 3.0 cm of sample nerve tissue was taken for HE staining to find out the number of nerve fibers. Musculoskeletal ultrasonography, electromyography and muscle strength test were performed in the postoperative follow-up for observations and evaluations of the effects of surgery. Average length and thickness of muscle were taken from the 48 patients in the "previous surgery group". The measurement was compared with the length of muscle fibers and the number of nerve fibers in the gracilis muscle of the 9 patients in study group. The cross-sectional areas (SCA) at contraction state (C) and resting state (R) of the superficial vastus of lateral thigh were taken from the 71 volunteers in the healthy control group, and the C/R ratio was calculated (CR value). All the 9 patients were included in the postoperative follow up by outpatient visits and via telephone or internet reviews to observe the recovery of muscle strength of the reconstruction of muscle dynamics.Results:In the study group, the number of nerve fibers shown by immunohistochemical HE staining was 1 088±213, with the CR value of graft muscle measured by musculoskeletal ultrasonography at 1.44±0.17. The wound healed smoothly without complication. The average time of postoperative follow-up for the 9 patients was 22.6 (10-38) months. Recovery of muscle strength was found at M5 in 6 patients and M4 in 3 patients. The appearance of the joints was normal. In the previous surgery group, the average muscle thickness of the superficial vastus lateralis muscle was 1.74 cm±0.35 cm and the length of muscle fiber was 8.86 cm±1.59 cm. In the healthy control group, the CR value of the superficial muscle vastus of lateral thigh was found at 1.17±0.12.Conclusion:Reconstruction of muscular power with partial muscle transfer of the superficial vastus of lateral thigh is proposed in this study.

Prostate cancer is a common malignancy in men, but rarely metastases to the ureter. A 68-year-old patient with ureteral metastases of prostate cancer was admitted to the hospital due to left lumbar and abdominal pain one month. Enhanced CT examination of urinary system after admission: mass in the middle of left ureter; multiple enlarged pelvic, retroperitoneal and left groin lymph nodes. After admission, the patient's PSA was 69.4 ng/ml, a prostate transrectal needle biopsy showed acinar adenocarcinoma. Under ureteroscopy, a smooth hard mass was seen 15 cm from the left ureteral orifice and completely obstructed the left ureter, the biopsy pathology showed infiltration of heteromorphic cell mass, and tumor could not be excluded. Laparoscopic ureteral tumor resection + end to end ureteral anastomosis was planned and intraoperative freezing was performed to determine the nature of the tumor. Due to severe adhesion around the tumor, partial nephrectomy, ureter and cystectomy were performed. The postoperative pathological diagnosis was ureteral metastasis of prostate cancer. The patient was treated postoperatively with abiraterone and goseririn for prostate cancer. CT examination 6 months after surgery showed multiple pelvic and retroperitoneal lymph node enlargement disappeared.

In May 2019, a patient who suffered with multiple foot metatarsus injury with soft tissues defect was treated in the Hand and Foot Microsurgery of Xi'an Fengcheng Hospital, by using chimeric peroneal artery for phase-1 reconstruction of metatarsus with folded fibular flap, foot cross arch and soft tissue defects. After 2 years, the arch of foot as intact without collapse. There was no arthritic lesions. The height, arc and width of metatarsus were very close to the healthy side. The flap and plantar were smooth without abrasion and ulceration. The patient could walk, run and stand with single-foot stand, and able to carry out heavy physical work continuously.

Objective:To explore the characteristics of diagnosis, treatment and prognosis of intermittent testicular torsion (ITT) in children.Methods:Retrospective review was conducted for the clinical data of 9 ITT cases from April 2014 to December 2019. The average age of all patients was 11.9 years (range 4.7-13.9 years). The involved side was left ( n=4), right ( n=4) and bilateral ( n=1). The main symptoms included severe pain of rapid onset and rapid resolution associated with nausea and lower abdominal pain ( n=1). The average number of painful episode was 2.4(1-5). There was a number of 1 painful episode in 4 emergency operative cases and more than 1 in 4 elective operative cases and 1 emergency operative cases. One patient of recurrent scrotal pain was relieved by manual detorsion. Among the five emergency operative cases, scrotal swelling and tenderness were found on the affected side, and the cremasteric reflex disappeared. Ultrasonic examination showed that two had absent testicular flow, one had decreased testicular flow, one had normal testicular flow with swelling epididymis and one with torsion of spermatic cord above testis. While among the 4 elective operative cases, the lie of the affected testis with cremasteric reflex was low on physical examination in all patients, compared with the contralateral testis. Atrophy of the affected testis were found in one case and horizontal lie in another one. The duration of prehospital symptoms ranged 4-24 hours during acute presentation in the 5 emergency patients, and 5-24 months in the 4 elective patients. All patients underwent testicular surgical exploration and bilateral orchidopexy. Results:Surgical exploration revealed no testicular ischemic infarction, and the rate of testicular salvage was 100%. A bell-clapper deformity (BCD) was found on all the affected testis and 2 contralateral testis as well. The median time of follow-up time was 10 months (range 1-69 months). No recurrence of testicular pain and other complications was found. Except for one case of testicular atrophy in the affected side before operation, the testicles of all patients recovered well without testicular atrophy.Conclusions:Intermittent testicular torsion is mainly manifested as repeated episodes of sudden onset unilateral scrotal pain that could be spontaneously resolved. The positive clinical findings include a horizontal position of the testes while standing and discrepancy in size of the testes. The ultrasonic examination is diversified because testicular torsion can be spontaneously relieved. Although the rate of testicular salvage is high in ITT, surgical exploration and bilateral scrotal orchiopexy should be carried out as early as possible to prevent recurrent painful episodes and testicular ischemic damage.
