Objective To compare the effectiveness of two minimally invasive methods: minimally invasive plating osteosynthesis (MIPO) and expandable intramedullary nail ing technique in treatment of middle third humeral shaft fractures. Methods The cl inical data were retrospectively analyzed and compared from 33 cases with middle third humeral shaft fractures between May 2004 and December 2008. All the patients were divided into 2 groups: 14 patients were treated with MIPOtechnique (group A) and 19 with expandable intramedullary nail ing technique (group B). In group A, there were 10 males and 4 females with an average age of 35 years (range, 21-51 years). The disease cause was traffic accident in 5 cases, tumbl ing in 6 cases, machine related trauma in 2 cases, crushed by a heavy object in 1 case. Six fractures were classified as AO type A, 6 as type B, and 2 as type C. The time from injury to operation was 3 to 11 days with an average of 5.9 days. In group B, there were 12 males and 7 females with an average age of 40 years (range, 19-68 years). The disease cause was traffic accident in 7 cases, tumbl ing in 8 cases, fall ing from height in 3 cases, crush injury in 1 case. Ten fractures were classified as AO type A, 8 as type B, and 1 as type C. The time from injury to operation was 2 to 6 days with an average of 4.2 days. There was no significant difference in general data between 2 groups (P gt; 0.05). Results The operation time was (104.6 ± 25.8) minutes in group A and (85.0 ± 35.7) minutes in group B, showing no significant difference (P gt; 0.05). Incision healed by first intention without iatrogenic radial nerve palsy in 2 groups. The patientswere followed up 21.4 months on average (range, 12-37 months) in group A and 20.5 months on average (range, 22-35 months) in group B. The X-ray films showed bony heal ing in all patients. The fracture union time was (16.4 ± 6.1) weeks in group A and (15.0 ± 2.5) weeks in group B, showing no significant difference (P gt; 0.05). The University of Cal ifornia Los Angeles (UCLA) End- Result scores were 34.1 ± 1.1 in group A and 31.8 ± 2.6 in group B and the Mayo Elbow Performance scores were 100 in group A and 97.6 ± 3.9 in group B; all showing significant differences (P lt; 0.05). Conclusion Good cl inical outcomes could be obtained when middle third humeral shaft fractures are treated by either MIPO or expandable intramedullary nail ing techniques. However, MIPO technique could offer better shoulder and elbow functional results.
ObjectiveTo compare the effectiveness of lateral approach minimally invasive plate osteosynthesis (MIPO) and helical plate MIPO in the treatment of proximal humeral shaft fractures. Methods The clinical data of patients with proximal humeral shaft fractures who underwent MIPO via lateral approach (group A, 25 cases) and MIPO with helical plate (group B, 30 cases) between December 2009 and April 2021 were retrospectively analyzed. There was no significant difference in gender, age, injured side, cause of injury, American Orthopaedic Trauma Association (OTA) fracture classification, and time from fracture to operation between the two groups (P>0.05). The operation time, intraoperative blood loss, fluoroscopy times, and complications were compared between two groups. The angular deformity and the fracture healing were evaluated according to anteroposterior and lateral X-ray films postoperatively. The modified University of California Los Angeles (UCLA) score for shoulder and the Mayo Elbow Performance (MEP) score for elbow were analyzed at last follow-up. Results The operation time in group A was significantly shorter than that in group B (P<0.05). However, the intraoperative blood loss and fluoroscopy times presented no significant difference between the two groups (P>0.05). All patients were followed up 12-90 months, with an average of 19.4 months. There was no significant difference in follow-up time between the two groups (P>0.05). In terms of the quality of postoperative fracture reduction, there were 4 (16.0%) and 11 (36.7%) patients with angulation deformity in group A and group B, respectively, and there was no significant difference in the incidence of angulation deformity (χ2=2.936, P=0.087). All fractures achieved bony union, there was no significant difference in fracture healing time between group A and group B (P>0.05); delayed union occurred in 2 cases and 1 case in group A and group B, respectively (healing time was 30, 42, and 36 weeks after operation, respectively). In group A and group B, 1 patient had superficial infection of incision, respectively; 2 patients and 1 patient had subacromial impact after operation, respectively; and 3 patients in group A had symptoms of radial nerve paralysis of different degrees; all of them were cured after symptomatic treatment. The overall complication incidence of group A (32%) was significantly higher than that of group B (10%) (χ2=4.125, P=0.042). At last follow-up, there was no significant difference in the modified UCLA score and MEPs score between the two groups (P>0.05). Conclusion Both lateral approach MIPO and helical plate MIPO can achieve satisfied effectiveness in the treatment of proximal humeral shaft fractures. Lateral approach MIPO may be beneficial to shorten the operation time, while the overall complication incidence of helical plate MIPO is lower.
Objective To investigate the cl inical effect of minimally invasive internal fixation percutaneous plate osteosynthesis (MIPPO) assisted by arthroscopy on tibial plateau fractures. Methods From September 2005 to December 2007, 29 patients with tibial plateau fracture underwent arthroscopy-assisted MIPPO, including 18 males and 11 females aged18-59 years old (average 34.7 years old). There were 8 cases of type II, 10 of type III, 5 of type IV, 3 of type V, and 3 of type VI according to Schatzker classification system. The fracture was combined with meniscus injury in 13 cases, anterior cruciate l igament injury in 4 cases, and medial collateral l igament injury in 3 cases. The time from injury to operation was 2-10 days. Firstly, the combined injury was treated under arthroscopy. Then, reduction of tibial plateau fractures was performed, bone grafting was conducted in the area of bone defect, and internal fixation using strut plates was performed after establ ishing subcutaneous tunnel via minimally invasion. Early rehabil itation activities were carried out for each patient 1 day after operation. Results No early compl ications such as poor heal ing of incisions, infections, and osteofascial compartment syndrome occurred. Over the follow-up period of 12-39 months (average 24 months), there was no failure of internal fixation, traumatic knee osteoarthritis, and inversion and eversion of the knee. The fractures healed within 3-4.5 months (average 3.5 months). The cl inical effect was excellent in 23 cases, good in 4 cases, and fair in 2 cases according to Lysholm knee rating system, and the excellent and good rate was 93.1%. Conclusion Arthroscopy-assisted MIPPO is a safe and effective way of managing tibial plateau fractures due to its features of minimal invasion, earl ier recovery, fewer compl ications, and simultaneous treatment of associated intra-articular injuries.
To explore the possibil ity of treating mid-distal humeral shaft fractures associated with radial nerve palsies with minimal invasive plating osteosynthesis (MIPO) techniques. Methods From April 2003 to October 2006, 10 patients with mid-distal humeral shaft fractures associated with radial nerve palsies were treated. All patients were male, aged 19-58 years. According to AO/ASIF classification, there were 4 cases of B1 type, 2 cases of B3 type, 1 case of A2 type, 1 caseof B2 type, 1 case of C3 type and 1 case of A3 type. A straight 4.5 mm dynamic compression plate was placed on the anterior aspect of humerus through two small incisions located on the anterior side of proximal and distal part of the arm. The radial nerve exploration was performed through a lateral small incision made on the fracture site. The fractures were then reduced by manual manipulation and the plate was fixated to the main fragments with 3 screws in each end of the plate. The postoperative compl ications, the bone heal ing time, and the recovery time of the radial nerve functions were recorded. The functions of the affected shoulder and elbow were assessed with UCLA and Mayo elbow performance score system respectively. Results All incision healed by first intention. Ten patients were followed up 9-36 months with an average of 15.7 months. The X-ray films showed that the union of fractures was achieved 12-16 weeks (13.6 weeks on average). The function of the radial nerves recovered completely 12-36 weeks (17.8 weeks on average) in 9 patients. The abductions of the affected shoulder were 150-170° (165° on average). The ROM of the elbows were 130-140° (135.5° on average). According to the UCLA shoulder scoring system, 9 patients achieved the excellent result and 1 patient achieved the good result. All the patients had the excellent results according to Mayo elbow performance score system. Conclusion The mid-distal humeral shaft fractures associated with radial nervepalsies can be treated with MIPO technique and the good results can be obtained.
Objective To investigate the effectiveness of sequential plate internal fixation in the correction of Madelung deformity after ulnar osteotomy and shortening. Methods The clinical data of 13 patients with Madelung deformity admitted between September 2015 and July 2021 were retrospectively analyzed. There were 5 males and 8 females with an average age of 18.3 years ranging from 17 to 23 years. The disease duration ranged from 12 to 24 months, with an average of 17 months. Three cases had a clear history of trauma. All patients had external radial deviation deformity and limited movement of the ulnar deviation, and the ulnar impact pain was significant during ulnar deviation movement; 9 patients had limited wrist joint supination movement, and the supination movement was normal. In the first stage, ulnar osteotomy and shortening combined with external fixator were used to correct wrist deformity in 13 patients. After operation, bone transfer was performed 6 times per day, with adjustments made every 4 hours, which was 1 mm per day. After the osteotomy was in place, the ulnar plate internal fixation was performed to reconstruct the ulnar stability in the second stage. The Cooney wrist joint score was used to assess the pain, function, range of motion, flexion and extension range of motion, and grip strength of the wrist joint before operation and before the removal of internal fixator. The subjective feeling and appearance satisfaction of patients were recorded. ResultsAfter the second-stage operation, all the 13 patients were followed up 10-22 months, with an average of 15 months. The deformity of wrist joint disappeared after operation, and the flexion, extension, and ulnar deviation were basically normal. There was no complication such as ulnar impingement sign, nonunion or infection. Wrist function, pain, and range of motion were significantly improved after operation, except for 1 patient who had no significant improvement in rotation and pain. The ulnar internal fixator was removed at 10-18 months after the second-stage operation. The scores of pain, function, range of motion, flexion and extension range of motion, and grip strength in the Cooney wrist score before removal of internal fixator significantly improved when compared with those before operation (P<0.05). Subjective and appearance satisfaction of patients were excellent in 9 cases, good in 3 cases, and fair in 1 case. ConclusionUlnar osteotomy and shortening with sequential plate internal fixation for correction of Madelung deformity, with mild postoperative pain, can effectively avoid bone nonunion, improve wrist joint function, and have significant effectiveness.
Objective To compare the effectiveness and shoulder function of reverse total shoulder arthroplasty (RTSA) and open reduction and internal fixation (ORIF) in the treatment of Neer three/four-part proximal humeral fractures in the elderly. Methods Randomized controlled analysis was conducted on 68 patients over 70 years old with Neer three/four-part proximal humeral fractures treated with RTSA or ORIF between January 2020 and June 2022. The patients were randomly divided into RTSA group (n=32) and ORIF group (n=36). There was no significant difference (P>0.05) in the baseline data such as age, gender, body mass index, injured side, Neer classification, and preoperative Charlson comorbidity index, visual analogue scale (VAS) score, Constant shoulder score, Oxford shoulder score (OSS), and hemoglobin (Hb). The operation time, intraoperative blood loss, reduction of Hb on the 3rd day after operation, hospital stay, total cost of hospitalization, complication incidence, range of motion of shoulder joint at 2 years after operation, VAS score before operation and at 5 days and 1 month after operation, Constant shoulder score and OSS score before operation and at 2 years after operation, and imaging results during follow-up were recorded and compared between the two groups.ResultsCompared with the ORIF group, the RTSA group had longer operation time, less intraoperative blood loss, and higher total cost of hospitalization (P<0.05). There was no significant difference in Hb reduction on the 3rd day after operation between the two groups (P>0.05). The VAS scores significantly improved in both groups at 5 days and 1 month after operation (P<0.05), but there was no significant difference between the two groups (P>0.05). All patients were followed up 26-35 months, with an average of 31.2 months. In the RTSA group, there were 2 cases of poor healing of superficial incision and 1 case of transient nerve injury. There was no complication such as bone resorption around the prosthesis, lucent band, prosthesis loosening, or periprosthetic fracture in all patients. In the ORIF group, there was 1 case of poor healing of superficial incision, 3 cases of nonunion of fracture, 1 case of arthritis secondary to humeral head necrosis, and 1 case of bone absorption of large tuberosity, and no displacement or fracture failure of internal fixation was found in all patients. There was no significant difference in the incidence of complications [9.4% (3/32) vs 16.7% (6/36)] between the two groups [OR (95%CI): 0.828 (0.171, 4.014), P=0.814]. In the RTSA group, 28 cases were graded 0 and 4 cases were graded 1 at 2 years after operation. Constant and OSS scores of RTSA group were significantly better than those of ORIF group (P<0.05). The Constant score was significantly better than ORIF group in activity and strength, range of motion, lifting, abduction, and external rotation (P<0.05), and there was no significant difference in pain, daily function, and internal rotation between the two groups (P>0.05). The RTSA group had a significantly greater range of motion in lifting, abduction, and external rotation than ORIF group (P<0.05), but there was no significant difference in internal rotation between the two groups (P>0.05). ConclusionApplication of RTSA as the initial treatment of Neer three/four-part proximal humeral fractures in the elderly can achieve better rehabilitation of joint activity and lower risk of early reoperation, and improve the quality of life of elderly fracture patients. However, the difficulty of revision and the high cost of treatment require the surgeon to pay full attention and strictly grasp the indications.

Methods From May 2008 to May 2009, we classified 22 cases of fresh displaced proximal humeral fracture according to the Neer classification. All patients were older than 60 years. There were two cases of two-part fracture, 16 cases of three-part fracture and four cases of four-part fracture. The open reduction and internal fixation with PHILOS plate was performed with the anterior deltopectoral approach. Results The 22 patients were followed up for 12 to 18 months with a mean period of 14.6 months. According to Constant-Murley Shoulder Score measurement, eight cases were graded as excellent, 10 good, three fair, and one poor with a excellent and good rate of 81.4%. Conclusion The open reduction and internal fixation with Philos plate is effective in treating elder patients with proximal humeral fracture.
ObjectiveTo systematically review the efficacy of percutaneous cannulated screw (PCS) versus plate fixation (PF) in the treatment of ankle fractures. MethodsThe Cochrane Library (Issue 5, 2014), PubMed, EMbase, CBM, CNKI, VIP and WanFang Data were searched up to May 28th 2014, for studies concerning the efficacy of percutaneous cannulated screw versus plate fixation for ankle fractures. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality of included studies. Then, meta-analysis was performed by using RevMan 5.1 software. Result A total of 10 studies (3 RCTs and 7 CCTs) involving 627 patients were included. The results of meta-analysis showed that:compared with the PF group, the PCS group was superior in time of the operation (RCT:MD=-6.78, 95%CI -11.95 to -1.60, P=0.01; CCT:MD=-9.76, 95%CI -13.68 to -5.84, P<0.000 01), blood loss during the operation (RCT:MD=-36.14, 95%CI -40.02 to -32.17, P<0.000 01; CCT:MD=-34.80, 95%CI -37.78 to -31.81, P<0.000 01) and the time of the fracture healing (RCT:MD=-1.16, 95%CI -1.51 to -0.81, P<0.000 01; CCT:MD=-1.55, 95%CI -2.97 to -0.13, P=0.03); However, there were no statistical differences between the two groups in complication rate (CCT:OR=0.48, 95%CI 0.08 to 2.81, P=0.41), AOFAS score excellent rate (RCT:OR=2.11, 95%CI 0.81 to 5.49, P=0.12; CCT:OR=1.58, 95%CI 0.75 to 3.30, P=0.23), and postoperative malleolus pain rate (CCT:OR=0.68, 95%CI 0.00 to 148.82, P=0.89). ConclusionCurrent evidence shows that PCS is superior to PF in shorting time of the operation, reducing blood loss during the operation, and shorting time of the fracture healing. However, the complication rate, AOFAS score excellent rate, and postoperative malleolus pain rate are similar for each operation. Due to the quality limitation of the CCTs, the conclusion are needed to be verified by more high quality RCTs in future.
Objective To compare the differences between volar and dorsal plate positions in the treatment of unstable fracture of distal radius. Methods From June 2000 to December 2006, 61 cases with fracture of distal radius weretreated, 27 males and 34 females aged 22-70 years (55.5 years on average), among which 18 cases were caused by traffic accidents and 43 cases falls. All cases were fresh closed fractures. All patients had AP and lateral X-ray films of the wrist preoperatively and 30 cases experienced CT scan. According to AO, there were 25 cases for B1, 18 for B2, 7 for B3, 7 for C1, and 4 for C2. All the cases were randomized into 2 groups: the wrist palmar group (group A, n=34) and dorsal group (group B, n=27), to perform volar and dorsal plate fixation, respectively. As to the measurement of fortune for the preoperative ruler and incl ination angle, group A were (—45.0 ± 53.0)º and (8.6 ± 3.1)º, respectively, and group B were (—40.0 ± 30.0)º and (7.3 ± 5.6)º, respectively. Preoperative radial shortened (12.0 ± 5.3) mm in group A, and (10.3 ± 4.2) mm in group B. Joint surface level was (4.3 ± 2.2) mm in group A, and (4.1 ± 3.3) mm in group B. Results All of the 61 cases were followed up for 6-27 months (16 months on verage). All the fractures were healed, the time to heal ing in group A was (8.2 ± 1.6) weeks, and in group B was (8.1 ± 1.2) weeks, and the difference was not significant (P gt; 0.05). As for the wrist function by Cartland-Werley scoring at the 8th week after operation, 7 cases were excellent, 10 good, and 17 poor in group A with the choiceness rate of 50.0%, while 7 cases were excellent, 11 good and 9 poor in group B with the choiceness rate of 66.7%. There was significant difference between the two groups (P lt; 0.01). And at the 24th week after operation, 21 cases were excellent, 9 good, and 4 poor in group A with the choiceness rate of 88.2%, while 18 cases were excellent, 5 good, and 4 poor in group B with the choiceness rate of 85.2%. There was no significant difference between the two groups (P gt; 0.05). As for radiological assessment by Sarmiento, device and palm incl ination angles in group A were (9.5 ± 3.1)º and (18.0 ± 8.2)º, respectively, and in group B were (11.0 ± 4.7) º and (16.0 ± 7.6)º, respectively. No radial shortening was found either in group A or in group B, and joint surface level in both groups were less than 1 mm. There was no significant difference between group A and group B in terms of all indicators postoperatively (P gt; 0.05), but there was significant difference when compared with preoperation (P lt; 0.001). With regard to comparison of postoperative compl ications between the two groups, there was no significant difference (P gt; 0.05) in early postoperative compl ications, but there was in long-term compl ications (P lt; 0.01). Conclusion The volar and dorsal plate positions may offer effective stabil ity for unstable distal radial fracture and early functional exercise. The volar plate position may influence the pronation function of the wris joint in the short run, while the dorsal plate position may cause more compl ications in the long run.
