  • PRELIMINARY EFFECTIVENESS OF I.T.S. LOCKING PLATE FOR INTRA-ARTICULAR CALCANEAL FRACTURES

    Objective To summarize the preliminary effectiveness of I.T.S. locking plate for intra-articular calcaneal fractures. Methods Between July 2010 and July 2011, 18 cases of intra-articular calcaneal fractures were treated. There were 10 males and 8 females with an average age of 46 years (range, 25-64 years). According to Sanders classification system, there were 3 cases of type II, 9 cases of type III, and 6 cases of type IV. The disease duration was 5-11 days (mean, 6 days). Open reduction and internal fixation with I.T.S. locking plate were performed via an L-shaped lateral extending incision. Results Superficial infection occurred in 1 case, and was cured after dressing changing; healing of incision by first intention was obtained in the other cases. Sixteen cases were followed up 14 months on average (range, 12-18 months). X-ray films demonstrated the bone union in all cases with an average union time of 12 weeks (range, 10-14 weeks). No implant failure or irritation of peroneal tendon occurred during follow-up. X-ray films showed subtalar post-traumatic arthritis with mild pain in 1 case at 11 months after operation, which was relieved by conservative treatment. At last follow-up, the Bouml;hler angle was improved from (12.9 ± 3.2)° preoperatively to (33.8 ± 4.0)° postoperatively, showing significant difference (t=22.78, P=0.00); the Gissane angle was improved from (83.6 ± 6.4)° preoperatively to (119.9 ± 8.5)° postoperatively, showing significant difference (t=17.02, P=0.00). The visual analogue scale (VAS) score was 1.3 ± 1.2, and the ankle and hindfoot scale of American Orthopaedic Foot and Ankle Society (AOFAS) was 80.3 ± 7.9 at last follow-up. Conclusion Treatment of intra-articular calcaneal fracture with I.T.S. locking plate can obtain a stable fixation, which is a safe and effective method.

    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.

  • MINIMALLY INVASIVE PERCUTANEOUS PLATE OSTEOSYNTHESIS TECHNIQUE FOR TREATMENT OF NEER II, III PARTS FRACTURE OF PROXIMAL HUMERAUS

    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.
