PURPOSE: To investigate the clinical effects of arthroscopically artificial ligament reconstruction with tensional remnant-repair in patients who are obese, and/or with demand for highly intensive sports, and/or with poor-quality ligament remnants. METHODS: A retrospective case series study was performed on patients treated by arthroscopically anterior talofibular ligament (ATFL) reconstruction with tensional remnant repair technique from January 2019 to August 2021. General data, including demographics, surgical time, and postoperative adverse events, were recorded. The American Orthopaedic Foot and Ankle Society score (AOFAS), foot and ankle ability measure (FAAM), visual analog scale (VAS), and anterior talar translation were measured preoperatively and at 6 weeks, 3 months, and 2 years postoperatively. Ultrasonography examination was performed preoperatively and 2 years postoperatively to evaluate the ATFL. Data were analyzed using SPSS 19.0. F test was used to analyze the pre- and postoperative VAS, FAAM, and AOFAS scores. The significance was set at p < 0.05. RESULTS: There were 20 males and 10 females among the patients with a mean age of (30.71 ± 5.81) years. The average surgical time was (40.21 ± 8.59) min. No adverse events were observed after surgery. At 2 years postoperatively, the anterior talar translation test showed grade 0 laxity in all patients. VAS score significantly decreased from preoperatively to 6 weeks, 3 months, and 2 years postoperatively (p < 0.001). Improvement of FAAM score and the AOFAS score from preoperatively to 6 weeks, 3 months, and 2 years postoperatively was statistically significant (p < 0.001). At 3 months postoperatively, most patients (23/30) could return to their pre-injured activities of daily living status. At 2 years postoperatively, all patients were able to return to their pre-injured activities of daily living status, and almost every patient (18/19) who expected highly intensive sports returned to sports with only 1 obese patient failing to achieve the goal. The ultrasonography examination at 2 years postoperatively showed that there was a linear band structure of soft tissue on the tension-rich fiber tape image from the fibular to the talar attachment sits of ATFL. CONCLUSION The novel arthroscopically artificial ligament reconstruction with tensional remnant-repair technique for ATFL achieved satisfactory clinical outcomes in the short and medium term after operation, and allowed early return to pre-injured activities, which could be a reliable option for patients with chronic lateral ankle instability.

OBJECTIVETo compare the clinical effects of PFNA and InterTAN for the treatment of unstable intertrochanteric fractures in the elderly patients.

METHODSFrom April 2012 to February 2014, 113 elderly patients with unstable intertrochanteric fractures were treated by PFNA or InterTAN. There were 64 cases in PFNA group, including 25 males and 39 females with an average age of (73.3±6.5) years old (ranged, 66 to 85);while 49 cases in InterTAN group, including 20 males and 29 females with an average age of (74.2±5.4) years old (ranged, 65 to 85). According to the AO classification, there were 48 cases of type A2, 16 cases of type A3 in PFNA group and 37 cases of type A2, 12 cases with type A3 in InterTAN group. The time interval from injury ranged from 3 to 8 days with an average of 4.7±1.2. The blood loss, operation time, fluoroscopy time, lateral cortex fractures of the proximal femur, healing time of fracture, femoral shaft fractures, femoral head screw cut-out, necrosis of the femoral head, femoral neck shortening and Harris score of patients at the last follow-up were compared between the two groups.

RESULTSFifty-eight patients in PFNA and 44 patients in InterTAN were followed up for 14 to 18 months with an average of 16.3±1.2. Wound healing was satisfying during the follow-up. Significant differences were observed between the two groups regarding the blood loss, operation time, fluoroscopy time. The complication rate of femoral shaft fractures, femoral head screw cut-out and femoral neck shortening in InterTAN group was less than that in PFNA group, showing significant difference between the two groups (<0.05). At the latest follow-up, the average Harris scores were 90.7±5.1 in PFNA group and 90.4±3.9 in InterTAN group, there was no significant difference between the two groups(>0.05).

CONCLUSIONSInterTAN with stronger anti-rotation function is more suitable for patients with early weight-bearing and it reduces the incidence rates of hip varus, femoral head screw cut-out and femoral neck shortening. However, for those patients with osteoporosis or unfit for surgery, PFNA is a good option. As the limited follow-up duration, long-term effects of the two surgical methods needs to be further observed and studied.

Objective To assess the clinical efficacy of fibular osteotomy with autogenous iliac bone graft for treatment of nonunion of the tibia. Methods A cohort of 45 patients with postoperative nonunion of tibia between Jul. 2008 and Jun. 2013 were treated by fibular osteotomy combined with autogenous iliac bone graft in Changhai Hospital of Second Military Medical University. According to anatomical classification, there were 29 cases of hypertrophic nonunion, 17 cases of atrophic nonunion and two cases of pseudoarthrosis. For primary fixation, 32 cases had plates internal fixation, 11 had intramedullary nail and two had external fixation. Eight patients with stable plate internal fixation were treated by fibular osteotomy with autogenous iliac bone graft, 35 patients with failed internal fixation and two patients with failed external fixation were treated by removing implant and exchanging compression plate with fibular osteotomy using autogenous iliac bone graft The status of fracture healing and relative complications were assessed by lateral and frontal X-ray. Functional recovery of the ankle was evaluated by Olerud-Molander Ankle Score (OMAS). Results The operation time was 1. 3-2. 5 (1. 7 ± 0. 5) h, the intra-operation blood loss volume was 200-500 (250. 0 ± 59. 6) mL, the fibular osteotomy length was 2-3 (2. 4 ± 0. 5) cm, and the volume of iliac grafting was 3-23 (7. 8 ± 1. 3) cm3. The follow-up time was 12-48 (16. 5 ± 3. 3) months and the fraction healing time was 3-11 (5. 6 ± 2. 4) months. The healing of 26(58%) patients took 3-5 months, 13(29%) patients took 6-8 months and 6(13%) patients took 9-11 months. Twenty-seven patients had no limb shortening, nine patients had limb shortening of <11 cm, six patients had limb shortening of 1-2 cm and three patients had limb shortening of >2 cm. The function of lower limb joints was excellent in 23 cases, good in 14 cases, common in 5 cases and bad m 3 cases at last follow-up. Conclusion The fibular osteotomy with autogenous iliac bone graft can create pressure on the broken bone end and increase the broken bone end contact area, promoting fracture healing and reducing complications.

Objective To analyze the clinical data of 915 elderly patients with hip fractures (≥ 80 years old) receiving surgical treatment in our department over the past 10 years, so as to summarize the surgical strategies of hip fractures in elderly patients. Methods We included 915 patients with hip fractures aged 80 years and over from Jun. 2007 to Jun. 2016. Based on preoperative preparation and evaluation, the general condition and underlying diseases of patients were adjusted individually during the perioperation, and then the suitable anesthesia methods and reasonable internal fixation were selected and the surgery was performed as soon as possible. Active early functional exercise, specialist nursing and health education were conducted after surgery. The waiting time for operation, operation time, hospital stays, bleeding volume, postoperative systemic and local complications and 1-year mortality were analyzed. Results The mean operation time of the 915 patients was (69.5±34.2) min (range 50-120 min), the mean bleeding volume was (278.3±56.8) mL (range 150-440 mL), and the mean hospital stay was (5.6±3.2) d (range 5-31 d). There were 210 cases having systemic and local complications, with 117 cases of systemic complications and 93 cases of local complications. Fourteen patients died, accounting for 1.5% (14/915) of the total. The patients were divided into <2 d group, 2-7 d group and >7 d group according to the waiting time for operation. Our results showed that the waiting time for operation was longer, the mortalities and incidences of complications of patients were higher, with a significant difference found between the 3 groups (P<0.05). Conclusion Active preoperative preparation and evaluation, right anesthesia methods, reasonable internal fixation according to the fracture site and type, adjusting general condition and underlying disease drug during the perioperation, early surgery, active specialist nursing, preoperative health education and individualized diagnosis can all contribute to the treatment of elderly patients with hip fractures, improving the clinical efficacy and reduce the complications effectively.

Objective To observe the application of the Green channel in the treatment of elderly patients with hip fracture, so as to provide a reference for the standardized treatment. Methods We retrospectively analyzed the clinical data of 115 elderly patients (≥75 years) with hip fractures treated in hospital from Jun. 2014 to Jun. 2015. The patients were treated through the Green channel (Green channel group, n=58) or received conventional treatment (normal group, n=57). The waiting time for operation, operation time, bleeding volume, hospital stay, and postoperative systemic and local complications during hospitalization were compared between the two groups. Results The waiting time for operation of patients in the Green channel group (median 43.6 h) was significantly shorter than that in the normal group (median 136.8 h, P<0.01), and the hospital stay of patients in the Green channel group ([4.3±1.2] d) was significantly shorter than that in the normal group ([8.5±2.5] d, P<0.05). There was no significant difference in the operation time or bleeding volume between the two groups (P>0.05). The incidence of complications of patients in the Green channel group (11/58, 19.0%) was significantly higher than that in the normal group (29/57, 50.9%; P< 0.01). The incidences of pulmonary infection and pressure sores of patients in the Green channel group were significantly lower than those in the normal group (3.4% [2/58] vs 14.0% [8/57], P<0.05; 3.4% [2/58] vs 15.8% [9/57], P<0.05). There was no significant difference in the incidences of pulmonary embolism, cerebral infarction, deep vein thrombosis, myocardial infarction, or incision infection between the two groups. Conclusion Application of the Green channel in the treatment of elderly patients with hip fracture can allow early surgery under suitable conditions, which is conducive to reduce hospital stay and postoperative complications, and can promote the recovery of hip function, indicating that the Green channel has an important significance for standardized treatment of eldery patients with hip fractures.

OBJECTIVETo design ABC damage variable and positioning system for acetabular fracture and explore the feasibility and clinical practical value of the system through the multi-center analysis of 1122 acetabular fractures.

METHODSAccording to acetabular three-column conception, and pelvic ring lesions damage direction caused by acetabular fracture domino effect and injury degree of proximal femur joint, it defined class A as any column acetabular fracture; class B as any two-column acetabular fracture; class C as front, dome and posterior mixture acetabular fracture. Lower case English letters a, m, p represented front, dome, posterior fracture, respectively. Acetabular damage variables: 1 was simple displaced fractures; 2 was comminuted fractures; 3 was compression fractures. Pelvic ring lesions damage variables: alpha was sacroiliac joints or sacroiliac fracture horizontal separation deflection; beta was sacroiliac joints or sacroiliac fracture vertical separation deflection; gamma was pubic symphysis separation/superior and inferior ramus of pubis fracture deflection; alpha beta gamma delta was compound floating damage. Proximal humerus joint damage variables: I was femoral head fracture; II was femoral neck fracture; II was intertrochanteric fractures of femur; IV was I to III compound fracture. The ABC damage variable positioning system for acetabular fracture was made up by the above-mentioned variables. The statistics from March 1997 to February 2010 showed 1122 cases acetabular fractures with 18 cases of double side acetabular fracture and 1140 cases of acetabular fractures. The pelvics anterior-posterior view, ilium and obturator oblique view, and 2/3D-CT materials were analyzed and researched.

RESULTSEach damage variables distribution situation in 1140 cases of acetabular fracture involved A in 237 cases (20.8%), B in 605 cases (53.1%), C in 298 cases (26.1%);front column fracture in 808 cases(70.9%), dome fracture in 507 cases (44.5%), posterior fracture in 1026 cases (90%). Acetabular variables: variabe 1 in 203 cases of simple displaced fracture (17.8%); variabe 2 in 516 cases of comminuted fracture(45.3%); variabe 3 in 421 cases of compression fracture (36.9%); 249 cases of pelvic ring lesions damage (21.8%), 75 cases femoral head fracture (6.6%); 18 cases of double side acetabular fracture and relative pelvic ring and proximal humerus joint variables (1.58%). Key part and curative effect elements of 1140 cases acetabular fracture: 507 cases of dome or posterior acetabular fracture (44.5%); 421 cases of compression fracture (36.9%); 249 cases of pelvic ring variables (21.8%); 75 cases of proximal humerus joint variables (6.6%); 486 cases of simple Aa/pl/2,Bapl/2 acetabular fracture (42.6% ).

CONCLUSIONCompression fracture, especially defected compression fracture, takes important part in acetabular damage variables, and also presents that acetabular fracture with pelvic ring and proximal femoral damage variables are not rare at all. The relationship of the acetabular fracture damage variables, and its percentage shows the key points and elements in clinical treatment: weight-bearing to dome accounts for 44.5%; compression to defects account for 36.9%, pelvic ring to float accounts for 21.8%; dome fracture to double side fracture account for 6.6%. The system has significant guiding effects on clinic in terms of evaluation of injury severity, anatomic localization, difficulty index, alternative strategy, operative approach, effect of treatment,and prognosis. And the most important thing is that the system creates the comparison of damage variables in same type of fracture and the communication of homo-language and explores a new method.

OBJECTIVETo investigate the therapeutic effects of closed reduction and percutaneous Kirschner pin fixation combined with plaster support for the treatment of supracondylar humerus fractures in children.

METHODSFrom June 2007 to December 2008, 27 patients with Gartland III supracondylar fractures were treated with closed reduction and percutaneous Kirschner wire fixation combined with plaster support. Among the patients, 18 patients were male and 9 patients were female, ranging in age from 6 to 12 years,with an average of 8.1 years. Fifteen patients were extension type, 12 patients were buckling type; fourteen patients were ulnar deviation, 13 patients were radial deviation. The duration from injury to treatment ranged from 0.5 to 8 days, averaged 3.6 days.

RESULTSTwenty-seven patients were followed up, and the duration ranged from 6 to 24 months, averaged 13.5 months. The healing time ranged from 4 to 6 weeks after surgery, with a mean of 4.5 weeks. Complications including implants loosening, fracture re-displacement, Volkmarm contraction, needle point or deep infection, ulnar nerve injury, myositis ossificans were found during follow-up. Two patients had postoperative elbow varus, but the varus angle was not more than 15 degree,which may be due to inappropriate functional exercise or early removal of external fixation. According to Flynn criteria, 19 patients got an excellent result, 5 good, 2 poor and 1 bad.

CONCLUSIONClosed reduction and percutaneous Kirschner wire fixation combined plaster support for the treatment of unstable supracondylar fractures in children has advantages including little trauma, reliable fixation, good elbow function and appearance.

OBJECTIVETo observe the effective of the injectable artificial bone combined with plate fixation for reconstructing the collapse tibial plateau fracture.

METHODSFrom June 2005 to January 2008,21 cases of collapse tibial plateau fracture of type Schatzker II, III were treated by injectable calcium sulfate bone substitute combined with supportive plate reconstruction including 16 males and 5 females with an average age of 35.3 years ranging from 27 to 62 years. The disease course was from 3 to 7 days (means 4 days). According to Schatzker classification, there were 17 cases of type II, 4 of type III. All patients preoperatively underwent radiography, CT scanning and three-dimensional reconstruction in order to accurately understand the extent of fracture and fracture collapse and the shattered fragments of the flip direction. All the fracture with collapse > 3 mm, without joint degeneration were selcected for surgical treatment. The knee joint function after fracture healing and recovery were evaluated by Lysholm scoring.

RESULTSAll patients were followed-up for from 6 months to 2.5 years (means 1.5 years). The X-ray films and features of all fractures showed anatomic reduction or near anatomic reduction, except one case of grade II severe comminuted fracture occurred a high degree of loss and platform reset ineffective after 6 months. The Lysholm scoring of knee function showed that the mean score was (88.3 +/- 5.2). The results were excellent in 12 cases,good in 7 cases, fair in 2 cases.

CONCLUSIONMinimally invasive injectable calcium sulfate bone combined with plate fixation for reconstructing the collapse tibial plateau fracture of type II, III can effectively prevent the further loss after reduction, to improve the long-term results. Minimally invasive injectable calcium sulfate as an artificial bone substitute materials has good prospects for clinical application.

OBJECTIVETo explore the external fixation for treatment of supracondylar femoral fractures after total knee replacement.

METHODSFrom June 2005 to July 2007, 7 cases of supracondylar femoral fracture after total knee replacement were treated with external fixation included 4 males and 3 females with an average age of 71 years ranging from 55 to 85 years. The fracture healing were observed and the knee function were evaluated by the HSS scoring.

RESULTSAll patients were followed-up for 6 to 23 months with an average of 12.5 months. The fracture healing time was from 6 to 12 weeks after operation (averaged 8.5 weeks). During the followed-up period, there were no infection and loosening, only one case occurred nail crossing delayed healing of skin. The HSS knee score was (60.6 +/- 16.0) before treatment and (77.6 +/- 11.6) after treatment according to HSS knee score criteria, the results were excellent in 2 cases, good in 4, and fair in 1.

CONCLUSIONApplication of external fixation for treatment of supracondylar femoral fracture after total knee replacement, especially in poor physical condition, high age patients is a more appropriate treatment.
