ABSTRACT

Objective:To analyze the necessity of anastomosis of the cutaneous nerve by comparing anterolateral femoral flaps with versus without anastomosis of the anterolateral femoral cutaneous nerve in the repair of extremity soft tissue defects.Methods:A retrospective analysis was made of the clinical data of 30 patients with extremity soft tissue defects who had been admitted to Department of Orthopedics, The Sixth People's Hospital affiliated to Shanghai Jiaotong University School of Medicine from September 2019 to March 2022. The patients were assigned into 2 groups according to whether the anterolateral femoral cutaneous nerve was anastomosed or not in the repair of extremity soft tissue defects using anterolateral femoral flaps. In the anastomosis groups of 14 cases, there were 7 males and 7 females, with an age of (46.4±15.2) years and a flap size of (22.4±7.3) cm×(8.5±1.3) cm. In the non-anastomosis group of 16 cases, there were 11 males and 5 females, with an age of (39.9±15.8) years and a flap size of (23.0±6.4) cm×(9.0±2.1) cm. The 2 groups were compared in terms of flap survival, Semmes-Weinstein recovery degree and area of monofilament tactile sensation, and time periods for temperature sensation and two-point discrimination.Results:There was no statistically significant difference between the 2 groups in the preoperative general data, showing they were comparable ( P>0.05). All the flaps survived completely without vascular crisis. In the anastomosis group, the time periods required for Semmes-Weinstein recovery of monofilament tactile sensation to the areas of 20.0%, 50.0%, and 80.0% [(2.5±0.7) months, (6.7±1.1) months, and (11.0±1.2) months] were significantly shorter than those in the non-anastomosis group [(3.6±1.3) months, (8.6±1.4) months, and (15.0±2.2) months], the recovery area at the last follow-up [100.0% (100.0%, 100.0%)] was significantly larger than that in the non-anastomosis group [84.6% (81.7%, 89.9%)], and the time period for recovery of temperature sensation [(3.9±0.7) months] significantly shorter than that in the non-anastomosis group [(6.1±1.1) months] (all P<0.05). The time for recovery of two-point discrimination in the 14 patients in the anastomosis group was (10.4±1.7) months while only 7 of the 16 patients in the non-anastomosis group recovered two-point discrimination after (14.7±1.4) months, showing a significant difference between the 2 groups ( P<0.05). Conclusion:In the repair of extremity soft tissue defects using anterolateral femoral flaps, compared with no anastomosis of the cutaneous nerve, anastomosis of the anterolateral femoral cutaneous nerve may ensure more or less the sensory recovery of the flaps.

ABSTRACT

Objective:To evaluate the clinical efficacy of staged surgery in treatment of calf Gustilo-Anderson type IIIC fracture.Methods:A retrospective case series was conducted to analyze clinical data of 16 patients with calf Gustilo-Anderson type IIIC fracture admitted to Shanghai Jiao Tong University Affiliated Sixth People's Hospital from January 2017 to December 2019. There were 12 males and 4 females, with the age of (38.6±8.2)years (range, 18-53 years). All patients had limb salvage treatment at one stage in the emergency department. The survival of the limb and the occurrence of vascular crisis were examined within one week after limb salvage. The second stage involved the repair of skin and soft tissue defects with the defect area from 12.0 cm×5.0 cm to 20.0 cm×8.0 cm using free flaps. The survival of the flap, vascular crisis, and donor site healing within two weeks after the flap procedure. The third stage used bone graft revision and bone lengthening technology to repair bone tissue. The lower extremity functional scale (LEFS) and Mazur ankle joint function score were used to evaluate the function of the affected limb before bone repair and at the last follow-up. The fracture healing and related complications were observed at the last follow-up.Results:All patients were followed up for (14.2±4.6)months (range, 8-20 months). At one stage, the limb-saving surgery was successful in all patients, among which one had vascular crisis. At second stage, free flaps survived in all patients, among which two had vascular crisis. All donor areas were healed by first intention. At third stage, the LEFS of the affected limb was increased from (32.0±7.4)points before bone repair to (48.0±10.2)points at the last follow-up ( P<0.01) and the Mazur score was increased from (50.9±15.3)points before bone repair to (73.8±11.9)points at the last follow-up ( P<0.01). All bone defects were repaired and healed without complications such as infection or osteomyelitis at the last follow-up. Conclusion:For calf Gustilo-Anderson type IIIC fracture, the staged strategy can effectively save limbs and restore limb function.

ABSTRACT

Objective To clarify the role of microsurgery in limb salvage procedure and its efficiency in long-term functional results through a retrospective review of patients who sustained severe injury of lower extremities and had been treated Shanghai 6th people's hospital, in recent 10 years. Methods Patients who sustained severe injury of lower extremities and treated with microsurgical techniques in January, 2006 to January, 2016 were studied. Patients' general information, classification of open fracture, and MESS were noted. The enrolled patients were divided into two groups (group A: primary microsurgical reconstruction;group B: non-microsurgical reconstruction ) according to whether primary microsurgical reconstruction was performed or not. Each group were also further divided into sub-group according to preoperative MESS (MESS<7 and MESS≥7). The reconstruction methods, hospitalization days, op-eration times, postoperative complications, as well as the SIP were then recorded for each groups. The differences of these data among each groups were analyzed and compared. Results The main objection was patient with Gustilo grade III open fracture, totally 548 patients were admitted, with 312 males and 236 females. The main age was 35.6 years old. The main etiology was road traffic accident (79.7%). There were 211 patients (38.5%) in group A, and 337 patients (61.5%) in group B. In group A, there were 37 patients in subgroup one (MESS<7), and 174 patients in sub-group two (MESS≥7). The rate of delayed amputation was 2.8%, while the complication rate was 11.8%. In group B, there were 181 patients in subgroup one(MESS<7), and 156 patients in subgroup two (MESS≥7). The rate of delayed amputation was 4.0%, while the complication rate was 13.3%. In long-term survey, the average VAS score of group B was higher than that of group A, but no significant difference was noted. The average VAS scores in 2 year postopera-tively in the subgroups (MESS≥7) were higher than those in the other subgroups (MESS<7). The results of SIP scores were similar with VAS scores in two groups. Conclusion The techniques of microsurgery has been promoting the successful rates and outcomes for limb salvage procedure over the recent decades. Meanwhile, the current evaluating system for se-vere limb injury needs to be updated to meet the demands of ever-developing limb salvage techniques.

ABSTRACT

The replantation of amputated finger (or limb) and the reconstruction of the thumb and fingers started in 1960s in China. With the development of microsurgical techniques, both finger replantation and reconstruction achieved worldwide significant success. And now it is not the survival rate but the function of replanted finger that attracted more attention. Moreover, the breakthrough of particular type of digital replantation has broadened its indications. In terms of reconstruction, not only that a great deal of experiences in dealing with different types of thumb defects was accumulated, but also more micro-surgeons focus on minimal invasion and reducing the damage to the donor area.

ABSTRACT

Objective To explore the effect and mechanism of local administration of thymosin β4 (Tβ4) on bone regeneration in a distraction osteogenesis model of rat fenur.Methods Sixty Sprague-Dawley rats were randomly divided into groups A,B and C in this study.A distraction osteogenesis model was established in the left femur after osteotomy.At the end of distraction period,the bone regeneration area in group A was subjected to no treatment,that in group B to injection of phosphate buffer saline (PBS),and that in group C to injection of Tβ4.On days 22,29 and 43 postoperatively,the rats from each group were randomly sacrificed and processed for observation of bone regeneration in the distraction osteogenesis area using radiography,Micro-CT,histology and immunohistochemical staining.RT-PCR was used to detect the expression of related genes as well.Results Radiography revealed that the bone regeneration in group C was superior to that in groups A and B on days 22,29 and 43 postoperatively.Micro-CT examination showed significantly increased bone volume (BV),bone mineral density (BMD) and ratio of bone volume to tissue volume (BV/TV) in group C on days 22,29 and 43 postoperatively,and significantly decreased ratio of bone surface area to bone volume on postoperative day 43 in comparison with groups A and B(P < 0.05).HE staining indicated that local capillary density was significantly higher in group C than in groups A and B after local administration of Tβ4 in the distraction osteogenesis.Immunohistochemical staining showed that the capillary density and osteoblasts in group C were higher than in groups A and B.RT-PCR results revealed significantly higher expression of eNOS and Osterix mRNA in the local callus in group C on postoperative day 22 than in groups A and group B (P < 0.05).Conclusion Local administration of thymosin β4 may promote bone formation,which is probably related to the increased expression of eNOS and Osterix.

ABSTRACT

The anterior cruciate ligament (ACL) injury in sports is a common knee joint injury.It is widely accepted to reconstruct ACL under arthroscopy with autologous patellar ligament or popliteal ligament fixed in tibial or femoral tunnel with interference screws.Interference screws are widely used as intra-articular fixation devices in ACL reconstruction.The ideal materials for interference screw provide rigid fixation of graft with high mechanical strength,long-lasting stiffness and the bioactivity to stimulate osteointegration and tendon-bone healing.Current interference screws are made of metals and bio-absorbable polymers.Metallic interference screws provide high mechanical strength and stiffness for tendon graft fixation,but require a second surgery for removal.Bioabsorbable interference screws made of polymers avoid second surgery for removal,but have lower mechanical strength and might cause aseprtic inflammation during its degradation as well as screw slip,tunnel enlargement and many other complications.Magnesium (Mg) has been investigated as a novel and potential biomaterials for biodegradable interference screws.Mg is essential nutrient element and has good biocompatibility.Its mechanical strength and related stiffness are much higher than that of biodegradable polymers and are close to cortical bone.Furthermore,the degradation rate of Mg in vivo could be modulated via techniques such as alloying.In previous studies,the relationship between screw design and its pull-out force has been investigated,based on which the design of interference screw is optimized.The mechanical properties (the ultimate load to failure and the related stiffness) of interference screws proved to be higher than that of bioabsorbable interference screws sharing the same design both in vitro and in vivo.Furthermore,Mg performs good biocompatibility without severe intra-articular inflammatory reactions,as well as unique bioactivities to promote osteointegration,mineral deposition and the regeneration of fibrocartilaginous entheses.The present study reviews the researches of Mg interference screws both in vitro and in vivo,gives reference for further research and has great importance for the application of Mg interference screws in ACL reconstruction.

ABSTRACT

BACKGROUND:Dorsal digital block refers to the commonly used anesthesia for adults in smal or moderate hand injury surgeries, but in recent years, modified transthecal digital block technique is gradualy respected, which is favored with a rapid and good effect and fewer complications. OBJECTIVE:To evaluate the clinical anesthetic outcomes of modified transthecal digital block and traditional dorsal digital block technique for the treatment of hand injury of adults in emergency by a prospective randomized controled study. METHODS:Totaly 60 adult patients with hand injury were enroled and divided into two groups of modified transthecal digital block and traditional dorsal digital block randomly. Blocks were performed by one single surgeon. The operation time, local anesthetic dose, onset time of anesthesia, duration of anesthesia, success rate of anesthesia, visual analogue scale scores and complications were recorded. RESULTS AND CONCLUSION:The anesthesia effects in the two groups were acceptable. There was no significant difference in the onset time of anesthesia, duration of anesthesia, success rate of anesthesia and complications between the two groups (P > 0.05). The operation time of anesthesia, local anesthetic dose, and visual analogue scale scores were significantly different between the two groups (P< 0.05). Modified transthecal digital block is more convenient and has less pain than the traditional root digital block, which is a safe and reliable anesthetic technique.

BACKGROUND:Studies have shown that the vacuum sealing drainage technology can effectively promote the wound healing, and it has a wide prospect of clinical application, but there are few reports addressing the treatment of diabetic foot. OBJECTIVE:To discuss the clinical effect of vacuum sealing drainage technology in the treatment of diabetic foot wounds. METHODS: Sixty diabetic foot patients were randomly divided into two groups: traditional treatment group, regulating blood sugar level, dressing and traditional debridement; vacuum sealing drainage group, conventional treatment combined with the vacuum sealing drainage technology. The clinical efficacy of two treatments for diabetic foot was evaluated. RESULTS AND CONCLUSION: Compared with the traditional treatment group, the vacuum sealing drainage showed better outcomes in switching frequency, stable blood sugar control, preparation time, wound healing time and cure rate (P < 0.05). It indicates that the vacuum sealing drainage technology in the treatment of diabetic foot ulcers can resolute wound inflammation, stimulate the growth of granulation, create a favorable surgical condition for secondary skin grafting or flap coverage, significantly shorten the treatment time, and exhibit better curative effects than the traditional treatment.

ABSTRACT

Objective To evaluate the clinical outcomes of open reduction and locking plate fixation with or without auto-iliac graft for humeral shaft nonunion.Methods Between January 2008 and May 2012,65 cases of humeral shaft nonunion were treated in our department.They were 48 men and 17 women,24 to 54 years of age (39.8 years).Of them,43 were atrophic and 22 hypertrophic.The radial nerve was exposed and protected during operation.After the nonunion portion was debrided,the humeral length was recovered.Next the fracture sites were fixated by a locking plate.The defected area was filled with auto-iliac graft if necessary.The visual analogue scale (VAS) scores and The Short Form-36 (SF-36) scores were documented after operation; the functional recovery was evaluated using Constant scoring at the last follow-up.Results The patients obtained a mean follow-up of 13.8 months (from 10 to 32 months).Of them,50 achieved clinical bone union after an average of 3.8 months (from 3 to 7 months).The remaining 6 cases showed no sign of union 9 months postoperatively.Of the 50 patients with union,the mean VAS score was decreased significantly from the preoperative 5.1 ± 3.2 points to the postoperative 1.4 ± 0.8 points,and the mean SF-36 score was increased significantly from the preoperative 45.7 ± 16.9 points to the postoperative 72.9 ± 18.5 points (P < 0.05).The function was scored at the last follow-up as excellent in 34 cases,good in 12,fair in 2 and poor in 2,giving an excellent to good rate of 92.0%.The radical nerve injury was repaired within 3 months postoperation in 3 patients.Rotation deformity occurred in 3 cases without obvious functional limitation.No implant complications such as plate breakage and screw loosening were observed.Conclusion Open reduction and locking plate fixation with or without auto-iliac graft is one effective treatment of humeral shaft nonunion,but damage to the radial nerve should be avoided and fixation of 6 layers of cortex should be maintained at both fracture ends during operation

ABSTRACT

Objective To evaluate the clinical effect of the reversed saphenous fasciocutaneous island flap combined with the VSD therapy in plate exposure of the distal tibia.Methods From January 2008 to July 2010,seven patients with hardware exposure following internal fixation of the distal tibia fracture were treated by VSD therapy and reversed saphenous fasciocutaneous island flap reconstruction.The VSD therapy was performed from 7 to 26 days after hardware exposure,and the flap transfer was performed 7 to 14 days after the VSD therapy.The size of the soft-tissue defect ranged from 4 cm × 2 cm to 13 cm × 4 cm.The mean follow-up was 10.6 months after the fracture (range,8-14 months).Results The average times of the VSD therapy was 1.3.After VSD was removed,the exposed hardware was covered by healthy granulation tissue in all cases.All flaps were successfully transplanted,and the size of flap ranged from 6 cm × 3 cm to 15 cm × 6 cm.Six of 7 flaps survived completely without further procedures.The necrosis of the distal margin of the flap occurred in 1 patient.A solid bony union was confirmed by the X-ray in all patients after 4-6 months postoperatively.No skin defects or fistulae were observed.Conclusion The combination of the reversed saphenous fasciocutaneous island flap and VSD therapy could save the exposed hardware and cover the soft tissue defects in the distal tibia.
