ObjectiveTo investigate the short-term effectiveness of modified tarsal sinus approach and traditional tarsal sinus approach in the treatment of Sanders Ⅱ-Ⅲ type calcaneal fractures.MethodsBetween January 2015 and August 2017, 53 patients with Sanders Ⅱ-Ⅲ type calcaneal fractures were selected and divided into observation group (21 cases, using modified tarsal sinus approach for fracture reduction after exposure of the subtalar joint below the long and short fibular tendon) and control group (32 cases, using traditional tarsal sinus approach) by random number method. There was no significant difference between the two groups in terms of gender, age, side, cause of injury, fracture type, injury to operation time, and preoperative B?hler angle, Gissane angle, visual analogue scale (VAS) core (P>0.05), which were comparable. The operation time, postoperative drainage volume, postoperative B?hler angle, Gissane angle, and postoperative angle improvement values of the two groups were recorded and compared. VAS score, American Orthopaedic Foot and Ankle Society (AOFAS) score, and short-form 36 health survey scale (SF-36) score were used to evaluate the effectiveness.ResultsAll the 53 patients successfully completed the operation without serious complications such as vascular and nerve injury and perioperative death. There was no significant difference in operation time and postoperative drainage volume between the two groups (P>0.05). Patients in both groups were followed up 12-36 months (mean, 17 months). No infection, fracture displacement, failure of internal fixation, and malunion of fracture occurred after operation. None of the patients underwent secondary joint fusion. There was no significant difference in fracture healing time between the two groups (t=0.30, P=0.77). The postoperative B?hler angle and Gissane angle at 2 days in the two groups were significantly improved when compared with those before operation (P<0.05); however, there was no significant difference in B?hler angle, Gissane angle, and improvement value between the observation group and the control group at 2 days after operation (P>0.05). VAS scores at 24 hours and 1 year after operation were significantly improved when compared with that before operation in both groups (P<0.05). There was no significant difference in VAS scores between the two groups at 24 hours and 1 year after operation (P>0.05). There was no significant difference in AOFAS scores between the two groups at 1 year after operation (t=1.46, P=0.15). However, the SF-36 scale score at 1 year after operation was significantly higher than that of the control group (t=2.08, P=0.04). At last follow-up, 2 patients in the observation group and 8 patients in the control group presented subtalar joint stiffness or pain, and there was no significant difference in the incidence between the two groups (χ2=1.98, P=0.16).ConclusionThe modified tarsal sinus approach for the treatment of Sanders Ⅱ-Ⅲ type calcaneal fractures has the advantages of minimal invasion, clear reduction under direct vision, reliable reduction and fixation, and low incision complications.
Objective To summarize the short-term effectivness of type IV Pipkin fracture through transtrochanteric approach with trochanteric osteotomy. Methods Between January 2007 and January 2010, 15 cases of type IV Pi pkin fracture were treated through transtrochanteric approach with trochanteric osteotomy. There were 9 males and 6 females with an average age of 42.5 years (range, 27-55 years). The causes of fractures included traffic accident (12 cases), fall ing from height (2 cases), and heavy pound injury (1 case). The time from injury to hospital ization was 4 hours to 7 days (mean, 2.3 days). All patients had l imitation of activity in the injured hips. The X-ray films and CT three-dimensional reconstruction indicated posterior dislocation of the hip joints and fractures of the femoral head and acetabulum, with no fracture of femoral neck. The locations of the femoral head fractures were under the round l igament in 9 cases and above the round l igament in 6 cases. Compl ications were treated firstly in all patients. The time from hospital ization to operation ranged from 2 to 10 days (mean, 4.5 days). Results All patients got primary wound heal ing with no early compl ication. All the patients were followed up 12-48 months with an average of 26 months. All osteotomies and acetabular fractures healed within 6 to 8 weeks. All patients achieved heal ing of femoral head fracture after 6-10 months. Mild heterotopic ossification occurred in 2 cases at 3 months after operation which were left untreated; and necrosis of the femoral head occurred in 1 case at 8 months after operation, was treated by total hip arthroplasty. At last follow-up, the flexion of the injuried hips ranged from 60 to 120° (mean, 92.5°). Based on Thompson et al. scoring scales, the results were excellent in 5 cases, good in 7 cases, fair in 2 cases, and poor in 1 case; the excellent and good rate was 80%. Conclusion Treatment of type IV Pipkin fracture through transtrochanteric approach with trochanteric osteotomy can provide good visual ization and protection of the blood supply of the femoral head.
ObjectiveTo investigate effectiveness and safety of right vertical infra-axillary thoracotomy (RVIAT) in surgical repair for intra-cardiac anomalies combined with patent ductus arteriosus (PDA).MethodsWe retrospectively analyzed the clinical data of 34 patients who underwent intra-cardiac correction of congenital heart defects and PDA ligation simultaneously via RVIAT in our hospital from August 2014 to August 2019. There were 25 males and 9 females with an age range of 0.5-6.1 years.ResultsThe length of incision was 3.0 (3.0, 3.5) cm. The operation time lasted 110.0 (90.0, 121.0) min. The cardiopulmonary bypass time was 45.5 (38.8, 63.5) min and the aortic cross-clamp time was 22.5 (14.8, 34.8) min. The bleeding volume was 20.0 (13.8, 20.0) mL. ICU stay time was 17.0 (5.5, 22.3) h, post-operative mechanical ventilation time was 4.0 (2.0, 6.0) h, total in-hospital cost was 46 (39, 51) thousand yuan. There was no mortality or reoperation during perioperative and follow-up period. Within the median follow-up of 636.0 days, 1 patient had minimal residual ventricular septal defect shunt while no new-onset scoliosis, funnel chest or pectus carinatum was detected. No bilateral mammary developmental asymmetry was observed in the female patients during the follow-up period. All the patients’ parents or guardians were satisfied with the right vertical infra-axillary aesthetic skin incision.ConclusionThe minimally invasive repair for intra-cardiac heart defects combined with PDA via RVIAT is a safe and effective method with minimal invasiveness and excellent cosmesis.
ObjectiveTo study the surgical treatments of scapula fracture through the muscle space of rotator cuff approach and the Judet approach, and to evaluate and compare the clinical results.MethodsBetween January 2014 and December 2015, 50 patients with scapula fractures were treated with open reduction and internal fixation of reconstruction plate. Twenty-four patients were treated through the muscle space of rotator cuff approach (group A), and 26 patients were treated through the Judet approach (group B). There was no significant difference in gender, age, cause of injury, type of fracture, and the interval between injury and operation (P>0.05). The operation time, intraoperative blood loss, and incision length were recorded, and the shoulder functions after fracture healing confirmed by X-ray films were evaluated according to the Hardegger’s scoring system.ResultsThe operation time, intraoperative blood loss, and incision length in group A were significantly lower than those in group B (P < 0.05). The incisions of the two groups healed by first intention. All patients were followed up 6-13 months (mean, 11.6 months) in group A and 7-15 months (mean, 12.1 months) in group B. According to Hardegger standard, the effectiveness was rated as excellent in 19 cases, good in 4 cases, and fair in 1 case, with the excellent and good rate of 95.8% in group A, and as excellent in 15 cases, good in 4 cases, fair in 5 cases, and poor in 2 cases with the excellent and good rate of 73.1% in group B. The difference in effectiveness between 2 groups was significant (χ2=4.81, P=0.03). X-ray films showed that the reduction and internal fixation were satisfied and the fractures healed in 2 groups. The fracture healing time were (29.86±8.38) weeks in group A and (30.05±7.99) weeks in group B, showing no significant difference between 2 groups (t=0.16, P=0.87). ConclusionCompared with the Judet approach, the muscle space of rotator cuff approach has advantages of clearly exposure, less muscular dissection, less intraoperative blood loss, less operation time, easier operation, and satisfied shoulder function can be obtained.
ObjectiveTo evaluate the surgical techniques, perioperative complications, clinical outcomes of the modified Stoppa approach in the treatment of acetabular anterior and posterior column fractures.
MethodsBetween March 2008 and October 2014, 42 cases of acetabular anterior and posterior column fractures were treated by modified Stoppa approach or modified Stoppa approach combined with iliac fossa approach, and the clinical data were retrospectively analyzed. There were 20 females and 22 males with an average age of 43.2 years (range, 19-68 years). Fractures were caused by traffic accident in 21 cases, by falling from height in 16 cases, and by heavy pound in 5 cases. The time from injury to operation was 3-15 days (mean, 6 days). According to fracture classification of Letournel-Judet, there were 20 cases of both column fractures, 15 cases of anterior and posterior hemi-transverse fractures and 7 cases of T-shaped fractures. The intraoperative blood loss, the amount of blood transfusion, the operation time, the volumn of drainage, and complication were recorded. Matta radiological standard was used to evaluate the reduction quality of fracture, and Merled'Aubigné-Postel system to evaluate hip function.
ResultsThe average intraoperative blood loss was 900 mL; the average amount of blood transfusion was 400 mL; the average volume of drainage was 110 mL; and the average operation time was 165 minutes. Intraoperative complications included 4 cases of tractive injury of obturator nerve and 2 cases of the external iliac vein injury, and postoperative complications included 2 cases of lateral femoral cutaneous nerve palsies and 1 case of deep vein embolism of lower extremity, which were improved after treatment. The patients were followed up 36 months on average (range, 12-48 months). There was no infection or heterotopic ossification. According to Matta radiological evaluation system, the reduction quality of fractures was rated as excellent in 21 cases, good in 16 cases, and poor in 5 cases, with an excellent and good rate of 88.1%. The healing time of fracture was 3.5-8.0 months (mean, 5.1 months). According to Merled'Aubigné-Postel system for hip function, 20 cases were graded as excellent, 15 cases as good, 4 cases as fair, and 3 cases as poor, with an excellent and good rate of 83.3% at last follow-up.

Objective To assess the effectiveness of the new anterolateral approach of the distal femur for the treatment of distal femoral fractures. Methods Between July 2007 and December 2009, 58 patients with distal femoral fractures were treated by new anterolateral approach of the distal femur in 28 patients (new approach group) and by conventional approach in 30 patients (conventional approach group). There was no significant difference in gender, age, cause of injury, affected side, type of fracture, disease duration, complication, or preoperative intervention (P gt; 0.05). The operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, hospitalization days, and Hospital for Special Surgery (HSS) score of knee were recorded. Results Operation was successfully completed in all patients of 2 groups, and healing of incision by first intention was obtained; no vascular and nerves injuries occurred. The operation time and intraoperative fluoroscopy frequency of new approach group were significantly less than those of conventional approach group (P lt; 0.05). But the intraoperative blood loss and the hospitalization days showed no significant difference between 2 groups (P gt; 0.05). All patients were followed up 12-36 months (mean, 19.8 months). Bone union was shown on X-ray films; the fracture healing time was (12.62 ± 2.34) weeks in the new approach group and was (13.78 ± 1.94) weeks in the conventional approach group, showing no significant difference (t=2.78, P=0.10). The knee HSS score at last follow-up was 94.4 ± 4.2 in the new approach group, and was 89.2 ± 6.0 in the conventional approach group, showing significant difference between 2 groups (t=3.85, P=0.00). Conclusion New anterolateral approach of the distal femur for distal femoral fractures has the advantages of exposure plenitude, minimal tissue trauma, and early function rehabilitation training so as to enhance the function recovery of knee joint.
ObjectiveTo assess the effect of polyurethane gelatum grommet positioning and Mayfield head holder positioning under suboccipital retrosigmoid approach in acoustic neuroma resection on patients' facial crushing.
MethodsRetrospective analysis of the clinical and nursing data of 90 patients treated by microsurgical surgery under the lateral prone position in our hospital from January 2013 to January 2014 was carried out. Patients in group A (n=28) were given grommet positioning, while those in group B (n=62) were given Mayfield head holder positioning, and then we compared the situation of facial crushing between the two groups.
ResultsIn group A, 5 patients showed abnormality including 2 cases of skin injury in lower frontozygomatic and mandibular area, 2 cases of lower conjunctival edema and 1 of co-existing skin injury in lower zygomatic area and lower conjunctival edema, and the crushing rate was 17.86% in group A. In group B, the crushing rate was 1.61% with one case of mandibular skin injury. There was a significant difference between the two groups (χ2=5.778, P=0.016).
ConclusionUnder suboccipital retrosigmoid approach for acoustic neuroma resection, Mayfield head holder positioning is better to avoid facial crushing.
ObjectiveTo investigate the feasibility of dissecting the external branch of the superior laryngeal nerve using endoscopic thyroidectomy via gasless unilateral subclavian approach combined with intraoperative nerve monitoring. MethodsThe clinical data of 30 patients who underwent the gasless nilateral subclavian approach endoscopic thyroidectomy in the Department of Head and Neck Surgery, Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine from October 2023 to February 2024 were retrospectively analyzed. ResultsAll operations were successfully completed under endoscopy approach without transfer to open surgery. A total of 29 cases of the external branch of superior laryngeal nerves were revealed in 30 cases, the revealed rate was 96.7%. The time for dissecting the external branch of the superior laryngeal nerve was 2–6 min [(3.6±2.3) min]. There was no obvious sound change related to the injury of the external branch of superior laryngeal nerve in postoperative patients. ConclusionFor the modified endoscopic thyroidectomy via gasless unilateral subclavian approach combined with intraoperative nerve monitoring, excellent anatomical protection of the external branch of the superior laryngeal nerve can be obtained.
ObjectiveTo investigate the effectiveness of treatment of locked lower cervical fracture and dislocation with anterior cervical fusion and internal fixation combined with the release of the interlocking facet through the Luschka joint and anterior lamina space.MethodsTwelve patients with lower cervical interlocking fracture and dislocation were analyzed retrospectively between January 2013 and June 2015. There were 7 males and 5 females, aged 25-59 years with an average age of 38.4 years. The disease duration was 9.6 hours to 100 days with an average of 7.3 days. There were 8 cases of unilateral locking and 4 cases of bilateral locking; 4 cases of old injury and 8 cases of fresh injury. The injured segments were 2 cases of C3, 4, 5 cases of C4, 5, 3 cases of C5, 6, and 2 cases of C6, 7. According to Meyerding classification, there were 9 cases of grade Ⅰ and 3 cases of grade Ⅱ. According to the functional classification of American Spinal Injury Association (ASIA), there were 2 cases of grade C, 6 cases of grade D, and 4 cases of grade E. The interlocking facet was released through the Luschka joint and anterior lamina space, and the anterior cervical fusion and internal fixation were used to treat the fracture and dislocation of the lower cervical spine. The recovery of spinal cord function was judged by the functional classification of ASIA; visual analogue scale (VAS) score, neck disability index (NDI) score, modified Japanese Orthopaedic Association (m-JOA) score were used to evaluate the clinical efficacy; the Cobb angle of fusion segment were observed by X-ray film. The intervertebral bone graft fusion was evaluated at 6 months after operation.ResultsThe average operation time was 78.30 minutes, the average intraoperative blood loss was 167.30 mL, and the average postoperative drainage volume was 58.12 mL. No blood transfusion was given during or after operation. During the operation, there was no accidental injury of large blood vessels, esophagus, and trachea; no laryngo edema, dysphagia, hoarseness, and cerebrospinal fluid leakage occurred after operation; no spinal cord injury or nerve root injury aggravated; the incision healed by first intention, and no infection occurred. All 12 cases were followed up 15-20 months, with an average of 16.5 months. The symptoms and function of the nerve injury were significantly improved when compared with that before operation. Re-examination of the cervical spine X-ray film at 6 months after operation showed that the Cage or bone graft was not displaced or broken, the screw was not loosened or detached, and the intervertebral graft fusion rate was up to 100%. At last follow-up, the ASIA grade, Cobb angle of fusion segment, neck pain VAS score, m-JOA score, and NDI score were significantly improved when compared with preoperative one (P<0.05).ConclusionThe effectiveness of treatment of locked lower cervical fracture and dislocation with anterior cervical fusion and internal fixation combined with the release of the interlocking facet through the Luschka joint and anterior lamina space is clear, which not only can make the injured segment get satisfactory reduction, immediate stability and reconstruction, and full decompression, but also can effectively prevent the secondary injury of spinal cord.
Objective To evaluate the effect of the modified extended iliofemoral approach on treatingcomplex acetabular fractures. Methods Thirty-six cases of complex acetabular fractures were treated by the open reposition and internal fixation by a modified extended iliofemoral approach. Results Thirty-sixcases were followed up for 7-46 months, with an average of 23.8 months. According to the Matta standard, anatomical reposition was performed in 24 cases, perfect reposition in 8 cases, and unsatisfactory reposition in 4 cases. By the modified d’Aubignepostel score, among the 36 cases, 22 had an excellent result, 9 had a good result, and 5 had a poor result. Conclusion Themodified extended iliofemoral approach facilitates the operative exposure of the anterior and posterior walls and both columns of the acetabulum in the surgically-treated acetabular fractures by the open reposition and internal fixation.Because of the reconstruction, the functions of the abductor muscle mass managed by the lagscrew-fixed osteotomies of the iliac crest, and greater trochanter, the patients can achieve a rapid rehabilitation of the joint.
