Treatment of proximal humeral fracture combined with lower glenoid fracture by internal fixation via the posterior axillary approach and the deltoid pectoralis major approach / 中华创伤骨科杂志

Objective:To investigate the efficacy of the posterior axillary approach combined with the deltoid pectoralis major approach in the treatment of proximal humeral fracture combined with lower glenoid fracture.Methods:From July 2019 to September 2021, 7 patients were treated at Department of Traumatic Othopeadics, The Sixth Hospital of Ningbo for proximal humeral fracture combined with lower glenoid fracture by internal fixation via the posterior axillary approach combined with the deltoid pectoralis major approach. They were 2 males and 5 females, aged from 51 to 78 years (average, 62.9 years). All fractures were closed ones. According to the Neer classification for the proximal humeral fractures, there were one case of type Ⅱ, one case of type Ⅲ, 3 cases of type Ⅳ and 2 cases of type Ⅵ. According to the Ideberg classification for the glenoid fractures, 5 cases were type Ⅰ and 2 cases type Ⅱ. The anteroposterior, lateral and axillary X-ray films of the affected shoulder were taken at 6 and 12 weeks, and 6 and 12 months after operation to follow up fracture healing and occurrence of complications. The Constant-Murley shoulder joint scores and the Disability of Arm Shoulder and Hand (DASH) scores for the upper limb dysfunction were recorded at the last follow-up for all patients.Results:All the 7 patients were followed up for 8 to 15 months (mean, 11.9 months). Bone union was achieved after an average of 4.3 months (from 3 to 6 months) in all patients. None of the functional activities was affected in all by postoperative shoulder joint instability, incision infection or axillary scar hyperplasia. At the last follow-up, their Constant-Murley scores averaged 83.4 points (from 55 to 92 points), and their DASH scores 13.5 points (from 4.2 to 33.3 points).Conclusion:In the treatment of proximal humeral fracture combined with lower glenoid fracture, the posterior axillary approach combined with the deltoid pectoralis major approach can lead to fine early curative efficacy due to their advantageous possibilities to allow for easy fracture reduction, reliable fixation and early rehabilitation.

Treatment of Sanders Ⅱ & Ⅲ calcaneal fractures with an absorbable stick plus Kirschner wire through the tarsal sinus incision / 中华创伤骨科杂志

Objective:To investigate the efficacy of treatment of Sanders Ⅱ & Ⅲ calcaneal fractures with an absorbable stick plus Kirschner wire through the tarsal sinus incision.Methods:From July 2017 to May 2020, 37 patients with 42 Sanders Ⅱ & Ⅲ calcaneal fractures were treated with an absorbable stick plus Kirschner wire through the tarsal sinus incision at The Third Ward of Department of Traumatic Orthopeadics, The Sixth Hospital of Ningbo. There were 25 males and 12 females, with an age of (48.2±5.6) years (from 20 to 69 years). The fractures were at the left side in 12 cases, at the right side in 20 and at bilateral sides in 5. By Sanders classification, 20 fractures were type Ⅱ and 22 ones type Ⅲ. Fracture union time and complications were recorded. Their B?hler and Gissane angles were compared between preoperation, postoperation and the last follow-up. The range of motion of the subtalar joint was evaluated by the Morrey method at 6 months postoperation. The functional recovery was evaluated by the American Society of Foot and Ankle Surgery (AOFAS) ankle-hindfoot score at 12 months postoperation.Results:The 37 patients were followed up for (15.2±2.7) months (from 13 to 18 months). There were no such complications as incision skin necrosis, Kirschner wire deformation, loss of fracture reduction or Kirschner wire infection. The anatomical morphology of the calcaneus was restored satisfactorily in the 37 patients. At preoperation, postoperation and the last follow-up, the B?hler angles were 13.3°±1.6°, 32.5°±5.5° and 32.7°±5.4° and the Gissane angles 78.3°±6.7°, 127.2°±6.7° and 128.0°±6.4°, respectively, showing significant differences between the preoperative and postoperative values ( P<0.05) but no significant differences between postoperation and the last follow-up ( P>0.05). The range of motion of the subtalar joint at 6 months postoperation was slightly limited in 25 cases and moderately limited in 12 cases, giving a rate of moderate and above limitation of 32.4% (12/37). By the AOFAS ankle-hindfoot score at 12 months postoperation, 12 cases were excellent, 21 ones good and 4 ones fair, giving a good to excellent rate of 89.2% (33/37). Conclusion:Treatment with an absorbable stick plus Kirschner wire through the tarsal sinus incision may lead to fine clinical efficacy for Sanders Ⅱ & Ⅲ calcaneal fractures.

Comparison of three internal fixation methods for distal femoral fractures of Müller types C2 and C3 / 中华创伤骨科杂志

Objective:To compare 3 internal fixation methods for the treatment of distal femoral fractures of Müller types C2 and C3.Methods:The clinical data of 58 patients were retrospectively analyzed who had been treated for distal femoral fractures of Müller types C2 and C3 at Department of Orthopaedic Trauma, Ningbo No. 6 Hospital from February 2013 to February 2017. They were divided into 3 groups according to the internal fixation method they had used. In the single incision locking plate group (group A) of 21 cases, there were 13 males and 8 females with an age of 50.6 years±12.9 years. In the double-incision locking plate combined with reconstruction plate group (group B) of 18 cases, there were 11 males and 7 females with an age of 53.5 years±13.0 years. In the single incision locking plate combined with reconstruction plate group(group C) of 19 cases, there were 10 males and 9 females with an age of 48.1 years±12.2 years. The 3 groups were compared in terms of operation time, intraoperative blood loss, intraoperative C-arm fluoroscopy, fracture healing time, incidence of postoperative complications, range of motion of the knee and knee functional recovery.Results:The 3 groups were compatible because there were no significant differences between them in their preoperative general data ( P>0.05). There were no significant differences between groups in the frequency of C-arm fluoroscopy, follow-up time, or incidence of postoperative complications ( P>0.05). The operation time in groups A and C (96.7 min±16.4 min and 101.9 min±16.5 min) and intraoperative blood loss for groups A and C (237.8 mL±47.5 mL and 253.6 mL±46.6 mL) were significantly less than in group B (114.9 min±20.1 min and 290.1 mL±60.9 mL) ( P<0.05); the fracture healing time for groups B and C (6.9 months±1.6 months and 6.6 months±1.7 months) was significantly shorter than for group A (8.4 months±1.9 months) ( P<0.05); the ranges of knee motion 12 months after operation in groups B and C (91.7°±16.7° and 90.9°±14.4°) were significantly larger than that in group A (78.8°±14.4°) ( P<0.05); the excellent and good rates of knee function 12 months after operation in groups B and C [77.8% (14/18) and 73.7% (14/19)] were significantly higher than that in group A [57.1%(12/21)] ( P<0.05). Conclusion:In the treatment of distal femoral fractures of Müller types C2 and C3, application of lateral locking plate and additional anterior locking reconstruction plate via the anterolateral incision at the distal femur can achieve rigid fixation without much damage to the surrounding soft tissues and lead to fine functional recovery of the knee joint because it has the advantages of single incision locking plate and double incision medial and lateral locking plates.

Clinical effect of perforated Kirschner wire tension band in the treatment of olecranon fractures in adults / 中华创伤杂志

Objective:To investigate the clinical effect of perforated kirschner wire tension band in the treatment of olecranon fractures in adults.Methods:A retrospective case-control study was conducted on 56 adult patients with olecranon fractures admitted in Ningbo NO.6 Hospital from May 2013 to February 2017. The perforated Kirschner wire tension band fixation was used in Group A ( n=24), while the common Kirschner wire tension band fixation was used in Group B ( n=32). Group A was composed of 16 males and 8 females at age of (34.0±12.1)years, and Group B was composed of 19 males and 13 females at age of (36.5±11.4)years. According to the Mayo classification, there were 7 patients with type I and 17 with type II in Group A, 15 with type I and 17 with type II in Group B. The operation time, bleeding volume, X transmission times, postoperative visual analogue score (VAS), fracture union time, loosening or failure of internal fixation, skin irritation and elbow joint function Broberg-Morrey score were compared between the two groups. Results:All patients were followed up for 15-21 months (mean, 18 months). In Group A, the operation time, bleeding volume, Xray transmission times, fracture union time and skin irritation were (79.6±22.5)minutes, (111.3±26.2)ml, (7.2±2.2)times, (3.7±0.6)months, 1 case, respectively. In Group B, the operation time, intraoperative hemorrhage, transmission times, fracture healing time and skin irritation were (94.3±27.5)minutes, (152.0±31.4)ml, (11.0±3.4)times, (4. 7±2.2)months, 9 cases, respectively. The difference between the two groups were all significant ( P<0.05). There were no significant difference in VAS, failure of internal fixation and elbow function Broberg-Morrey score between the two groups ( P>0.05). Conclusions:Compared with the anatomic plate, the perforated Kirschner wire tension band in the treatment of adult patients with olecranon fractures cannot only reduce the operation time and transmission times, reduce the intraoperative bleeding volume, but also shorten the fracture union time and avoid the occurrence of skin irritation and other complications.

Application of peripheral nerve block combined with intravenous rapid channel anesthesia in the lower extremity orthopedic surgery of the elderly patients / 中国基层医药

Objective@#To investigate the effect of peripheral nerve block combined with venous fast track anesthesia on elderly patients undergoing lower extremity orthopedic surgery.@*Methods@#From September 2015 to December 2017, 64 senile patients with lower extremity orthopedic surgery in the Fifth Hospital of Ningbo were selected in the research.According to the different methods of anesthesia, the patients were divided into observation group (30 cases, application of combined intravenous peripheral nerve block and fast track anaesthesia), and the control group (34 cases, application of simple intravenous general anesthesia). The heart rate, average arterial pressure, spontaneous breathing recovery time, extubation time, complication rate and cognitive function scores of the two groups were compared.@*Results@#The heart rate and average arterial pressure of T1 and T3 in the observation group were significantly lower than those in the control group (P<0.05). The spontaneous breathing recovery time[(8.32±3.26)min] and extubation time[(9.69±4.29)min] in the observation group were significantly shorter than those in the control group[(18.24±5.23)min and (27.24±4.58)min](t=8.961, 15.756, all P<0.05). The incidence rate of postoperative complications in the observation group (3.33%) was significantly lower than that in the control group (20.59%)(χ2=4.338, P<0.05). The cognitive function score of the observation group was significantly higher at 4 h and 8 h after surgery than that of the control group (t=6.745, 8.494, all P<0.05).@*Conclusion@#Peripheral nerve block combined with intravenous fast-track anesthesia is very feasible for elderly patients undergoing lower limb orthopedic surgery.The time for patients to recover from spontaneous breathing and extubation is shorter, and the risk of complications such as delirium, restlessness, nausea and vomiting is lower.

Proximal humeral internal locking system combined with fibular strut allograft for treatment of Neer 3-and 4-part factures of proximal humerus in the elderly / 中华创伤骨科杂志

Objective To compare proximal humeral internal locking system (PHILOS) combined with fibular strut allograft versus simple PHILOS for the treatment of Neer 3-and 4-part factures of proximal humerus in the elderly.Methods A retrospective study was conducted of 157 elderly patients with Neer 3-or 4-part facture of proximal humerus who had been treated at Department of Orthopaedics,Ningbo No.6 Hospital from May 2013 to October 2016.They were 76 males and 81 females,aged from 60 to 88 years (average,76.1 years).According to the Neer classification,100 cases were 3-part fractures and 57 4-part fractures.Of them,35 were treated by PHILOS combined with fibular strut allograft (group A) and 122 by PHILOS alone (group B).At the last follow-up,the 2 groups were compared in terms of shoulder joint activity (anteflexion,abduction,internal rotation and external rotation),visual analogue scale (VAS),American Shoulder and Elbow Surgeons (ASES) score,Constant-Murley score,postoperative height loss of the humeral head,humeral head varus angle,complication rate and secondary surgery rate.Results The 157 patients were followed up for 12 to 22 months (mean,16.8 months).The fracture healing time was 13.0 ± 3.8 weeks in group A and 15.6 ± 4.2 weeks in group B,showing a statistically significant difference (P ＜ 0.05).At the last follow-up,for groups A and B respectively,anteflexion was 135.6° ± 17.7° versus 125.4° ± 23.6°,abduction 132.5°±22.7° versus 117.5°±32.7°,external rotation 30.2°± 18.7° versus 21.6°± 17.2°,internal rotation T9 versus T11,VAS score 0.6 ±0.9 points versus 0.9 ± 1.2 points,ASES score 90.2 ±6.8 points versus 82.2 ± 12.3 points,Constant-Murley score 88.5 ±3.6 points versus 72 ±4.9 points,postoperative height loss of the humeral head 0.9 ± 0.1 mm versus 4.2 ± 0.4 mm,and humeral head varus angle 1.2° ± 0.2° versus 4.5° ± 1.9°.The differences between the 2 groups were all statistically significant (P ＜ 0.05).There were no significant differences between the 2 groups in complication rate [14.28％ (5/35) versus 22.13％ (27/122)] or in secondary operation rate[2.85％ (1/35) versus 8.19％ (27/122)] (P ＞ 0.05).Conclusions In the treatment of Neer 3-and 4-part factures of proximal humerus in the elderly,PHILOS combined with fibular strut allograft can improve therapeutic efficacy,because it can provide good support for the medial column of the proximal humerus and the humeral head and thus facilitate the intraoperative reduction of the fracture.
