Objective To evaluate the effectiveness of locking plates for Neer 3- and 4-part proximal humerus fractures. Methods A retrospective analysis was made on the clinical data of 77 patients with 3- or 4-part proximal humerus fractures, who underwent open reduction and internal fixation of locking plates and were followed up more than 12 months between July 2008 and May 2011. There were 39 males and 38 females with an average age of 54.2 years (range, 18-81 years). Fractures were caused by falling in 47 cases, by traffic accident in 16 cases, by falling from height in 4 cases, by sporting in 5 cases, and by other reasons in 5 cases. The time between injury and operation was 2-16 days (mean, 4.5 days). According to Neer classification, there were 54 cases of 3-part fracture and 23 cases of 4-part fracture. The Constant scores, visual analogue score (VAS), and the complications were evaluated during follow-up. Results After operation, healing of incisions by first intention was obtained in 76 cases and healing by second intention in 1 case. All patients were followed up 12-36 months (mean, 18.5 months). At last follow-up, the Constant score was 71.1 ± 11.9; the results were excellent in 18 cases, good in 24 cases, fair in 25 cases, and poor in 10 cases with an excellent and good rate of 54.5%. The VAS score was 2.8 ± 2.2. Bone nonunion occurred in 2 cases; the other patients had bone union within 2-6 months (mean, 3.2 months). The complications occurred in 25 cases (32.5%). Revision surgery was performed in 15 patients (19.5%). Conclusion The treatment of Neer 3- and 4-part proximal humerus fractures remains challenging. Anatomic reduction, stable fixation, and reduced humeral head blood supply disruption may lead to a satisfactory outcome.
Objective To compare the effectiveness between operative and non-operative treatment for 3- and 4-part proximal humeral fractures in elderly patients. Methods Between January 2009 and January 2011, 35 patients with 3- or 4-part proximal humeral fractures were treated with open reduction and locking plate internal fixation (n=20, operative group) and with closed reduction and splint or cast fixation (n=15, non-operative group). There was no significant difference in gender, age, etiology, fracture type, and disease duration between 2 groups (P gt; 0.05). The postoperative rehabilitation protocol was performed in 2 groups. Results All patients of the operative group achieved healing of incision by first intention. All patients were followed up 16 months on average (range, 12-20 months). The X-ray films showed that the other fractures healed except 1 case (5.0%) nonunion in operative group. Varus malunion was found in 1 case (6.7%) of non-operative group and 2 cases (10.0%) of operative group. Humeral head necrosis was found in 1 case respectively in 2 groups (5.0% and 6.7%). There was no significant difference in complication incidence between 2 groups (P gt; 0.05). The Constant-Murley scores of non-operative group and operative group were 64.7 ± 9.9 and 66.8 ± 11.8 at last follow-up respectively, showing no significant difference (t=0.59, P=0.47). Conclusion Operative treatment has similar effectiveness to non-operative treatment for 3- and 4-part proximal humeral fractures. In elderly patients, non-operative treatment should be chosen.
Objective To evaluate the cl inical significance of minimally invasive percutaneous plate osteosynthesis (MIPPO) appl ied in Neer II, III parts fractures of proximal humeraus. Methods The cl inical data were retrospectively analyzed, from 30 patients with Neer II, III parts fractures of proximal humeraus in accordance with selection criteria, who were treated with manual reduction and plaster external fixation (11 cases, non-operative group) or with MIPPO (19 cases, operative group) between January 2008 and May 2010. In non-operative group, there were 6 males and 5 females with an average age of 60 years (range, 56-80 years) and with an average time of 10 hours (range, 3-24 hours) between injury and reduction, including 8 cases of Neer II and 3 cases of Neer III. In operative group, there were 13 males and 6 females with anaverage age of 65 years (range, 45-78 years) and with an average time of 3 days (range, 1-5 days) between injury and operation, including 9 cases of Neer II and 10 cases of Neer III. There was no significant difference in gender, age, fracture type, and time from injury to operation (P gt; 0.05). The shoulder joint function before and after treatments was evaluated according to Constant-Murley Score (CMS) and American Shoulder and Elbow Surgeons’ Form (ASES) scoring systems. Results Thirty patients were followed up. In operative group, the follow-up time ranged from 11 to 18 months (mean, 12 months); all incisions healed by first intention with no compl ication of internal fixation failure, infection, or nerve injury. In non-operative group, the follow-up time ranged from 9 to 15 months (mean, 11 months). The X-ray films showed that fractures healed without humeral head necrosis in 2 groups. The bone heal ing time in operative group and non-operative group was (11.47 ± 2.48) weeks and (11.82 ± 2.44) weeks, respectively, showing no significant difference (t=0.369, P=0.889). The CMS score and ASES score at each time point after treatment were significantly better than those before treatment (P lt; 0.05); the CMS scores in operative group were better than those in non-operative group at 3 weeks, 3 months, and 1 year after treatment (P lt; 0.05); and the ASES score in operative group was better than that in non-operative group at 3 weeks and 3 months after treatment (P lt; 0.05), but no significant difference was found at 1 year after treatment (P gt; 0.05). Conclusion MIPPO fixation using the locking compression plate is an effective option for Neer II, III parts fractures of proximal humeraus. It can provide good functional recovery of the shoulder joint so that patients can get back to their normal l ife as soon as possible.
Objective To review the biomechanics of internal fixators for proximal humeral fractures, and to compare the mechanical stabil ity of various internal fixators. Methods The l iterature concerning the biomechanics of internal fixators for proximal humeral fractures was extensively analyzed. Results The most important things for best shoulder functional results are optimal anatomical reduction and stable fixation. At present, there are a lot of methods to treat proximal humeral fractures. Locking-plate exhibites significant mechanical stabil ity and has many advantages over other internal fixators by biomechanical comparison. Conclusion Locking-plate has better fixation stabil ity than other internal fixators and is the first choice to treat proximal humeral fractures.
Objective To compare the efficacy and indication of the three different surgical methods in the treatment of the senile osteoporotic comminuted proximal humerus fracture. Methods From January 2006 to April 2008, 70 senile patients with osteoporotic comminuted proximal humerus fracture were randomly divided into three groups to receive different surgical methods. There were 21 patients in the group A receiving Kirschner tension band or screw internal fixation, 37 patients in group B receiving internal fixation of locking proximal humeral plate, and 12 patients in group C receiving humeral head replacement. There were 36 males and 34 females aged 53-76 years old (average 61.9 years old). All the fractureswere closed, osteoporotic, and III and IV-part according to Neer classification. The disease course was 1-8 days (average 2.8 days). There was no significant difference among three groups in terms of basel ine information (P gt; 0.05). The effective antiosteoporosis therapy was given during perioperative period. Results All the incision healed by first intention. All patients reached anatomical or almost anatomical reduction without compl ications such as postoperative infection, neurovascular injury, and nonunion of bone. Seventy patients were followed up for 9-20 months (average 11.5 months). The heal ing time of the fracture was 8-12 weeks in group A and group B, the average heal ing time was 10.5 weeks in group A and 10 weeks in group B, and there was no significant difference between two groups (P gt; 0.05). Group C presented with no sign of prosthesis loosening or shoulder dislocation. Six cases in group A suffered from frozen shoulder, pain or acromion impingement syndrome 6 months after operation and obtained various degrees of improvement via functional exercises. One of them had humeral head avascular necrosis 12 months later and achieved fair recovery after performing humeral head replacement. Two cases in group B had frozen and painful shoulder 6 months after operation and achieved fair recovery after functional exercises. One cases in group C had frozen shoulder and poor performance of abduction and upl ifting and achieved improvement after exercises. The rest patients achieved satisfactory curative effects. The incidence of compl ication was 28.6% in group A, 5.4% in group B, and 8.3% in group C. The incidence of complication in group A was significantly higher than that of group B and group C (P lt; 0.05), and there was no significant difference between group B and group C (P gt; 0.05). Neer scale system was adopted to evaluate the postoperative shoulder function, the excellent and good rate was 66.7% in group A, 78.4% in group B, and 83.3% in group C. The excellent and good rate in group A was significantly less than that of group B and group C (P lt; 0.05), and there was no significant difference between group B and group C (P gt; 0.05). Conclusion The senile osteoporotic comminuted proximal humerus fracture treated by surgery can obtain satisfied results. Most patients can use locking plate fixation. Those with poor general condition can use Kirschner wire fixation with tension band or screws, but this method is subject to certain constraints. For some elder patients with humeral head necrosis and humeral head crushed, priority should be given to the use of humeral head replacement.

ObjectiveTo assess the effect of surgical treatment or conservative treatment on the clinical outcomes for displaced 3-part or 4-part proximal humeral fractures in elderly patients. MethodsWe searched CNKI (between January 1979 and April 2014), Wanfang Data (between January 1982 and April 2014), Medline (between January 1946 and April 2014), PubMed (between January 1966 and April 2014), Embase (between January 1974 and April 2014) and Cochrane Database of Systematic Reviews (between January 2005 and April 2014) for randomized controlled trials comparing surgical treatment and conservative treatment for displaced 3-part or 4-part proximal humeral fractures in elderly patients. The data were extracted and a Meta-analysis was made using RevMan 5.2. ResultsFive randomized controlled trials with a total of 226 patients were accepted in this Meta-analysis. The differences of Constant scores[WMD=0.48, 95%CI (-4.39, 5.35), P=0.85], incidences of avascular necrosisr of the humeral head[RR=0.66, 95%CI (0.37, 1.16), P=0.15], incidences of nonunion[RR=0.56, 95%CI (0.20, 1.58), P=0.27], incidences of osteoarthritis[RR=0.35, 95%CI (0.10, 1.22), P=0.10] between the two groups were not statistically different. The difference of incidences of additional surgery after primary treatment was statistically significant[RR=3.52, 95%CI (1.18, 10.45), P=0.02]. ConclusionThe results does not support the surgical treatment to improve the shoulder function when compared with conservative treatment for treating elderly patients with displaced 3-part or 4-part proximal humeral fractures. But surgical treatment increases the incidence of additional surgery after primary treatment. Considering surgery can increase the trauma and economic burden of patients, so the conservative treatment is suggested.
ObjectiveTo analyze the outcome and prognostic factors of using locking plate for treating proximal humerus fracture. MethodsBetween January 2005 and January 2012, 45 aged patients with a displaced 3-part or 4-part fracture of the proximal humerus were treated by locking plate. Range of motion and Constant-Mudey score were observed during the follow-up. ResultsForty-three patients were followed up from 12 to 48 months with an average of 18 months. The mean final Constant-Mudey score was 72.3±9.5 and 6 of them needed a second surgery. In addition to fracture type, other prognostic factors included redisplacement (4 cases, 9.3%), nonunion (3 cases, 7.0%), crashing (3 cases, 7.0%), necrosis of the humeral head (6 cases, 14.0%) and screw cut-out (5 cases, 11.6%). Among the patients with disrupted medial calcar, 4 needed a second surgery at the final follow-up, 3 had redisplacement, 2 had nonunion, and 2 had screw cut-out. ConclusionLocked screw-plates provide more secure fixation of fracture in aged patients, but the complication rate remains high. We suggest anatomic reduction, and plate and screws position, length of the screws, the medial cortical contact and stability may be the chief prognostic factors affecting the shoulder function following a proximal humeral fracture.
