ABSTRACT

Objective:To investigate the efficacy of 3D-printed quantitative bone implants assisting second-stage Masquelet technique for the treatment of long-segment bone defect following Gustilo type IIIB and IIIC tibial fractures.Methods:A retrospective case series analysis was made on 26 patients with long-segment bone defect following Gustilo type IIIB and IIIC tibial fractures treated in Wuxi Ninth People′s Hospital from July 2015 to December 2020, including 20 males and 6 females; aged 19-63 years [(46.5±4.5)years]. Gustilo classification was type IIIB in 23 patients and type IIIC in 3. In the first stage, all patients had thoroughly emergent debridement, removal of all free bone pieces, restoration of the length and force line plus externally fixion, and vacuum sealing drainage (VSD) of the residual wound. After 2-7 days, the external fixation was removed and replaced by internal fixation, with the bone cement filling in the defect area and the free flap covering the wound. The length of tibial bone defect was 5-14 cm [(6.3±0.4)cm], and the tibial defect volume was 12.2-73.1 cm 3 [(33.6±9.2)cm 3]. In the second stage (6-19 weeks after injury), the bone cement was removed, followed by autologous bone grafting. Prior to bone grafting, digital technology was used to accurately calculate the bone defect volume, and an equal volume of bone harvesting area was designe to produce the 3D printed osteotomy template. Bone grafting was conducted after bone removal according to the osteotomy template during operation. The success rate of one-time iliac bone extraction, bone harvesting time, and bleeding volume were recorded. Pain in the bone extraction area was evaluated by visual analogue score (VAS) at 1 day and 1 month after operation and at the last follow-up. Wound healing, complications, and bone healing were observed. Life quality was evaluated by health survey brief form (SF-36) including scores of physical component summary (PCS) and mental component summary (MCS) before bone grafting and at the last follow-up. Results:All the patients were followed up for 13-53 months [(32.3±12.5)months]. One-time iliac bone extraction was successful in all the patients. Bone harvesting time was 15-30 minutes [(21.0±2.5)minutes]. The bleeding volume was 50-120 ml [(62.3±29.0)ml]. The VAS was 1-4 points [(1.2±0.9)points] at 1 day after operation, higher than these (0.0±0.0)points at 1 month after operation and at the last follow-up (all P<0.01). Totally, 25 patients obtained wound healing after operation, except for 1 patient with superficial wound infection after bone grafting that was healed by dressing change. There was 1 patient with bone infection after 3 months of bone grafting that was healed by repeated surgery with Masquelet technique in the first and second stage. Besides, 2 patients had symptoms of cutaneous nerve injury in the iliac donor area. The time of bone healing was 4-7 months [(5.8±0.8)months]. The scores of PCS and MCS in SF-36 at the last follow-up were (73.6±12.8)points and (83.6±13.2)points, significantly higher than those before bone grafting [(46.8±0.5)points, (60.7±2.0)points] (all P<0.01). Conclusion:Second-stage Masquelet technique with 3D printed quantitative bone implants for the treatment of long-segment bone defect following Gustilo type IIIB and IIIC tibial fractures is associated with shortened bone harvesting time, attenuated pain, reduced complications, accelerated bone healing and improved function.

ABSTRACT

Objective:To characterize the radial head fracture combined with capitulum cartilage injury (CCI).Methods:The data of 110 patients were analyzed retrospectively who had been treated for radial head fracture at Department of Orthopaedics, The Ninth People's Hospital of Wuxi from January 2011 to May 2020. They were 62 males and 48 females, aged from 17 to 74 years (average, 44.10 years). According to the finding of intraoperative exploration whether CCI was complicated or not, they were assigned into a CCI group and a CCI-free group. The diagnosis, location, size, type, operation method and postoperative recovery of CCI were observed in CCI group. The 2 groups were compared in terms of preoperative general data, range of forearm motion before and after operation and functional recovery of the limb by Mayo elbow performance score (MEPS).Results:CCI was complicated in 25 cases (type Ⅰ in 7 ones, type Ⅱ in 12 ones and type Ⅲ in 6 ones), involving all Mason types of radial head fracture, and located at the lateral capitellum in 13 cases, at the posterolateral capitellum in 9 cases and at the anterolateral capitellum in 3 cases. CCI was diagnosed before operation in 13 cases by physical examination after local anesthesia and imaging examination with a rate of 48% (12/25) for missed diagnosis. The preoperative flexion and extension (61.8°±13.7°) and rotation (60.0°±24.2°) in CCI group were significantly less than those in CCI-free group (77.7°±23.0° and 79.9°±21.9°) ( P<0.05); the Mason types of radial head fracture in CCI group were significantly more serious than those in CCI-free group ( P<0.05). There was no significant difference between the 2 groups in age, gender, combined injury, treatment of radial head fracture, follow-up time, range of forearm motion at the last follow-up or MEPS score ( P>0.05). Conclusions:CCI was complicated in 22.73%(25/110) of the radial head fractures in this cohort and found in all Mason types of radial head fracture, and mostly located at the lateral and posterolateral capitellum. CCI is likely to be missed by imaging examination. In patients with mild radial head fracture and suspected CCI, positive physical examination after local anesthesia is valuable for diagnosis of CCI complication and operative indication. Care should be taken to detect CCI complication by intraoperative exploration in surgery of radial head fracture.

ABSTRACT

Objective:To compare the clinical effect of buttress plate fixation and cannulated screw fixation of Regan-Morrey type II ulnar coronoid fractures.Methods:A retrospective case control study was made on 53 patients with Regan-Morrey type II ulnar coronoid fractures admitted to Wuxi No.9 People 's Hospital from April 2015 to January 2018,including 36 males and 17 females,aged from 21 to 63 years[(36.3±7.1)years]. Among them,24 patients were treated using buttress plates(plate group),and 29 patients using cannulated screws(screw group). The operation time and fracture healing time were documented. The visual analogue score(VAS),range of motion of elbow flexion and extension and forearm rotation and Mayo elbow performance score(MEPS)were assessed at postoperative 1,3,6 months and at the last follow-up. The incidence of complications was observed as well. Results:All patients were followed up for 15-18 months[(15.9±1.3)months]. The operation time in plate group[(150.6±24.2)minutes]was longer than that in screw group[(126.8±18.3)minutes]( P<0.05). There was no significant difference in fracture healing time or VAS between the two groups( P>0.05). After 1,3,6 months and during the last follow-up,the range of motion of elbow joint flexion and extension in plate group[(87.2±5.8)°,(109.2±7.1)°,(121.3±6.2)°,(127.3±5.4)°]was higher than that in screw group[(70.5±9.1)°,(90.2±4.5)°,(108.3±5.1)°,(116.2±4.6)°],the range of motion of forearm rotation in plate group[(78.3±9.1)°,(98.7±8.6)°,(130.2±7.1)°,(139.2±6.7)°]was higher than that in screw group[(60.1±5.1)°,(80.6±8.7)°,(116.1±5.5)°,(127.3±4.1)°],and the MEPS in plate group[(30.6±7.6)points,(68.1±6.1)points,(90.2±4.3)points,(95.2±2.1)points]was higher than that in screw group[(27.2±8.1)points,(54.1±7.1)points,(82.1±5.3)points,(88.2±5.2)points](all P<0.05). In plate group,one patient sustained superficial wound infection at postoperative 1 week,which was healed uneventfully after surgical debridement and antibiotic therapy;two patients had heterotopic ossification without addition surgery. In screw group,three patients presented screw loosening and fracture redisplacement during early movement,which was healed by reducing the intensity of elbow functional exercise and prolonging the protection time of brace;four patients had heterotopic ossification,among which one combined with elbow stiffness showed improved range of motion of the elbow after elbow release at postoperative 12 months. The incidence of complications in plate group[13%(3/24)]was lower than that in screw group[26%(7/29)]( P<0.05). Conclusion:For Regan-Morrey type II ulnar coronoid fractures,the buttress plate fixation is superior to the cannulated screw fixation in fixation strength,recovery of elbow function and incidence of complications in regardless of longer operation time.

ABSTRACT

Anterolateral thigh flap (ALTF) was first reported by XU Dachuan et al. of China in 1984. After almost four decades of in-depth researches by scholars at home and abroad, a broad variety of different types of the flaps are now widely in use, which had been successfully applied to close the wounds from calvaria to planta pedis. The ALTF provides opportunities to save lives and improves functions, and is applied in multiple organ reconstructions in various forms. The ALTF was therefore called "Top-to-bottom" and "Omnipotent flap". This article concludes the milestones and progresses in the research of ALTF in China, including applied anatomy, localisation of perforating branch, clinical applications and protection of donor sites.

ABSTRACT

Objective To investigate the characteristics and types of die-punch fracture of the distal radius (DPFDR) based on three-column theory as well as its application value.Methods The imaging data of 560 cases of DPFDR were reviewed which had been treated at The Ninth People's Hospital of Wuxi from June 2007 to June 2017.They were 305 males and 255 females,aged from 13 to 95 years,with an average of 46.4 years.According to the three-column theory,the 560 DPFDR cases were divided into a single column group and a double column group.According to the fracture site and morphology,the former was further characterized as volar,dorsal,split and collapse types while the latter as metaphyseal,articular surface and mixed types.After being familiarized with our new classification,2 radiologists were asked to classify 100 cases of DPFDR independently.The inter-and intra-observer agreements were analyzed with Kappa statistics.Results There were 65 cases of single column DPFDR,including 3 ones of volar type,13 ones of dorsal type,14 ones of split type and 35 ones of collapse type;there were 495 cases of double column DPFDR,including 130 ones of metaphyseal type,155 ones of articular surface type and 210 ones of mixed type.The intra-observer Kappa coefficient was 0.877-0.937 and the intra-observer kappa was 0.916-0.959,showing high agreement.Conclusions Due to differences in violence nature and intensity,wrist position and bony quality of the patient at the time of injury,axial violent transmission may cause different types of die-punch fracture at the intermediate column of the distal radius and different types of mild radial column fractures as well.As our new classification may well characterize the site and morphology of DPFDR,it has high consistency to guide surgical treatment and prognosis judgment.

Objective To evaluate the clinical value of MDCTA (Multi-detector computed tomographic angiography) in reconstruction of the soft tissue defect of the limbs combined with the main vascular defects by using Flow-through anterolateral thigh flap.Methods From September,2013 to May,2016,12 cases of limb soft tissue with main vascular defects were examined by MDCTA.The length of vascular defect was measured.The length of bridging vessel needed to design a Flow-through anterolateral thigh flap was measured.The points of anterolateral thigh flap perforator were positioned.The relationship between the perforation and the trunk vascular pedicle was defined.The outcomes were evaluated based on Berton scores for upper extremities and John-Wruh scores for lower extremities.Results The length of the main vascular defects,the positions of flap perforators and the configuration of vascular pedicles were successfully imaged through MDCTA.The length of the main vascular defects were 5-12 cm,which was consistent with the intraoperative findings.The length of bridging vessel for the defects were 7-14 cm,which was enough for the vascular defects.There were not vessel grafts.Twenty perforators were imaged by MDCTA preoperatively,and 22 perforators were found during the operations,which means 2 perforators were not imaged.All flaps survived completely.All patients were followed-up from 6 to 21 months (average,11 months).According to the Berton scores for upper extremities and John-Wruh scores for lower extremities,the excellent/good were 6 in 8 cases and 4 in 4 cases,respectively.Conclusion MDCTA can be used to evaluate the pedicle conditions of the free Flow-through anterolateral thigh flap for the reconstructions.It is worthy to be popularized in clinical application.

ABSTRACT

Objective To study the surgical method of repairing the defects of the hand with the free antero-lateral thigh perforator flap without carrying the source of blood vessels and the fascia. Methods From February, 2013 to October, 2016, 8 cases of hand defects with tendon and bone exposure.Looking for the thickest perforator in the anterolateral thigh region by using the Multidetector computed tomography angiography(MDCTA)and color Doppler Sonography(CDS). Find the perforator in the superficial fascia,cut a small part of the fascia lata and vastus lateralis,cut off the pedicle at the musculocutaneous perforator.Cover the defects with flap after debridement. Regular follow-up include:the healing of the wound,the texture,shape and sensation of the skin flap, the scar and complica-tions of the donor area. Results All flaps survived in 8 cases, in one case,there are 1.0 cm necrosis in the distal flap, after debridement, direct suture. All patients were followed up for 6-12 months. The flaps were soft and normal color, restore the protective touch. The donor site healed well, linear scar, no itching and dysfunction. Conclusion Free anterolateral thigh perforator flap without source blood vessels and fascia lata is a good method for the repair of hand defects.

ABSTRACT

BACKGROUND: Lateral locking plate is a classical fixation method to treat lower and distal femoral fractures. However,the incidences of delayed healing, nonunion, plate extubation, and internal fixation rupture exceed 20% after internal fixation.OBJECTIVE: To compare the effectiveness of augmentation plating and single plating for distal and lower femoral fractures with medial comminution.METHODS: Totally 60 patients of lower and distal femoral fractures with medial comminution treated with open reduction and plate fixation were divided into augmentation plating (treatment group, 28 cases) and single lateral plating (control group, 32 cases). We observed the operation time and blood loss, recorded the out-off-bed rehabilitation time, full weight bearing time and complication. The functionary recovery of knee joint was evaluated according to Schatzker-Lambert method for distal femoral fractures in final follow-up.RESULTS AND CONCLUSION: (1) All patients were followed for at least 12 months. All incisions were healed by first intention. (2) The operation time and blood loss in the treatment group were greater than those in the control group (P <0.05). (3) The healing time (3.11±0.31 months), out-off-bed rehabilitation time (4.36±0.91 weeks), full weight bearing time (3.67±0.62 months), complication (0) and excellent and good rate of knee functionary recovery (100%) in the treatment group were better than those in the control group [(5.65±2.33), (7.25±1.02), (6.03±2.61) months, 8, 65.6%] (P < 0.05). (4)Although augmentation plating for treatment of lower and distal femoral fractures with medial comminution prolongs operation time and increases surgical blood loss, the results including the healing rate, complication and satisfaction rate are superior to those treated with single lateral plating.

ABSTRACT

Objective@#To investigate the clinical therapy for Gustilo type Ⅲ B、ⅢC open fractures with skin and soft tissue defects on the upper extremities.@*Methods@#From July 2014 to July 2016, 19 patients with Gustilo type Ⅲ open fractures (type ⅢB 12 cases , type ⅢC 7 cases) and soft-tissue defects in upper extremity were admitted, including 14 males and 5 females , aged 22 to 59 years (average 42 ). All the cases were treated by staged treatment. In the first stage, early debridement, nerves, vessels and tendons repairment, fixation of the fractures, VSD for the wound were performed. One patient underwent amputation 5 days after first operation. All the other 18 patients received flap transplantion, including 10 anterolateral thigh perforator flaps, 3 latissimus dorsal muscular flaps and 5 free lateral arm flaps.@*Results@#8 patients were followed up for an average duration of 14.5 months(ranged from 7 to 23 months). Partial necrosis happened at the distal end of one anterolateral thigh perforator flap and healed with skin-grafting.1 flap encountered vascular complication which survived with 5cm-in-width skin necrosis at the distal end of the flap after successful surgical exploration. 1 case had superficial infection at wound. The wounds at donor sites were primarily healed except for 1 case with skin graft necrosis and superficial infection. All the other flaps survived completely. The patients received 2-6 operations each. The average hospital stay was 34 days (12-71 days). All Skin flap texture was soft and had varying degrees of pigmentation. The flap sensory recovery was S2 in 4 cases, S3 in 9 cases, S4 in 5 cases. 1 case had obvious scar hyperplasia.@*Conclusions@#Staged surgical treatment in Gustilo type Ⅲ open fractures with soft-tissue defects in upper extremity provide a high survival rate of flaps and satisfactory results. The treatment is well tolerate by patients.

ABSTRACT

Objective@#To summarize 7 adjacent V-Y advanced perforator flaps for defects at donor sites leaving by six commonly-used flaps.@*Methods@#From May 2007 to Jan. 2014, 66 cases with hands and feet skin defects, tendon and bone exposure were treated with reverse island flap(15 cases), thumb dorsal artery island flaps (9 cases), dorsal metacarpal artery island flaps (9 cases), abdominal pedicle flaps (9 cases), free anterolateral thigh flaps (15 cases), sural nerve retrograde island flaps (9 cases). The defects at donor sites were covered by adjacent V-Y advanced perforator flaps, including dorsal metacarpal perforator flap, snuffbox perforator flap, dorsal carpal perforator flap, deep iliac circumflex artery musculocutaneous perforating branches flap, outer knee perforator flap, medial thigh perforator flap, proximal posterior tibial artery.@*Results@#All the six common flaps survived with average healing period of 15 days. Only one adjacent V-Y advanced outer knee perforator flap underwent partial necrosis at the proximal flap end which healed after dressing. All the other V-Y advanced flaps survived. The patients were followed up for 5-24 months (8 on average) with satisfactory flap texture and color both at reconstructed area and donor sites. The adjacent joints had normal movement function.@*Conclusions@#Adjacent V-Y advanced perforator flap is an important method for closure of defects at donor sites. It has the advantages of no sacrifice of main artery, satisfactory result and easy performance.

ABSTRACT

Objective To study the clinical application of the 2 flaps based on the proximal and distal perfo-rator from ulnar artery in the repair of defect of 2 fingers and evaluate the outcome of the procedures. Methods From January,2014 to January,2015, 8 cases with skin and soft tissue defects of 2 fingers were treated simultaneous-ly with the distal and proximal perforator flap of ulnar artery in ipsilateral limb. The area of the distal flaps ranged from 2.5 cm×4.5 cm to 4.0 cm×6.5 cm. The area of the proximal flaps ranged from 3.5 cm×4.5 cm to 4.5 cm×6.5 cm. The followed-up were performed at 3rd, 6th and 12th months post-operation. The patients' satisfaction of the appear-ance and function of repaired finger and working situation were investigated. The postoperatively pain prick , touch and temperature sensation of the flaps were examined. Total active range of motion (TAM) of the finger points were measured. Results All flaps survived. Two flaps got plastic surgery at 5 months post-operation. The pain , tempera-ture and light touch sensation were restored 12 months after the surgery. Five patients returned to work again 12 months after the operation. Conclusion The distal and proximal perforator flap has their own characteristics, can be used simultaneously to repair skin and soft tissue defects of the two fingers.
