Treatment of middle third humeral shaft fractures: minimal invasive plate osteosynthesis versus expandable nailing

The purpose of this study is to compare the results of middle third humeral shaft fractures treated with minimally invasive plate osteosynthesis (MIPO) with those treated with an expandable nail technique. Thirty-four patients with middle third humeral shaft fractures were retrospectively analyzed and divided into two groups: group A included 15 patients treated by MIPO and group B included 19 patients treated with an expandable intramedullary nail. The operation time, postoperative complications, time to fracture union, the UCLA End-Result score of the shoulder, and Mayo elbow performance index (MEPI) were recorded and compared. The mean operation time in group A was 108.3 ± 28.7 min and 85.0 ± 35.7 min in group B, a difference of 23.3 (27.4%) minutes (P < 0.05). There were no cases of iatrogenic radial nerve palsy or superficial infection in either group. All fractures united. The mean time to fracture union in group A was 16.1 ± 6.0 (8–32)weeks, versus 15.0 ± 2.5 (10–21) weeks in group B (P > 0.05). One case of delayed union was identified in group A. The mean UCLA End-Result score in group A was 34.2 ± 1.1 points (31–35 points)and 31.8 ± 2.6 points (26–35) in group B (t = 3.318 P = 0.002, P < 0.05). All the patients had excellent elbow functions. In surgical treatment of middle third humeral shaft fractures, MIPO appeared to offer advantages in terms of better shoulder and no iatrogenic radial nerve injuries, although technically more difficult and time consuming.     

Minimally invasive plate osteosynthesis for humerus diaphyseal fractures

Background:

Minimally invasive plate osteosynthesis (MIPO) technique is reported as a satisfactory procedure for the treatment of humeral shaft fractures by the anterior approach by several authors. However, none of the published reports had a significant follow-up nor have they reported patient outcomes. We evaluated the clinical, radiographic, and functional outcome over a minimum follow-up of 2 years using the same MIPO technique to humeral shaft fracture.

Materials and Methods:

32 adult patients with diaphyseal fractures of the humerus treated with MIPO between June 2007 and October 2008 were included in the study. Patients with metabolic bone disease, polytrauma, and Gustilo and Anderson type 3 open fractures with injury severity score >16 were excluded from the study. All cases were treated with closed indirect reduction and locking plate fixation using the MIPO technique. The surgery time, radiation exposure, and time for union was noted. The shoulder and elbow function was assessed using the UCLA shoulder and Mayo elbow performance scores, respectively.

Results:

Of the 32 patients in the study, 19 were males and 13 were females. The mean age was 39 years (range: 22–70 years). Twenty-seven of the thirty-two patients (84.3%) had the dominant side fractured. We had eight cases of C2 type; five cases of C1 and A2 type; four cases of B2 type; three cases each of B3, B1, and A1 type; and one case of A3 type of fracture. The mean surgical time was 91.5 minutes (range: 70–120 minutes) and mean radiation exposure was 160.3 seconds (range: 100–220 seconds). The mean radiological fracture union time was 12.9 weeks (range: 10–20 weeks). Shoulder function was excellent in 27 cases (84.3%) and good in remaining 5 cases (15.6%) on the UCLA score. Elbow function was excellent in 26 cases (81.2%), good in 5 cases (15.6%), and fair in 1 case (3.1%) who had an associated olecranon fracture that was fixed by tension band wire in the same sitting.

Conclusion:

MIPO of the humerus gives good functional and cosmetic results and should be considered one of the management options in the treatment of humeral diaphyseal fractures.     

Minimally Invasive Plating Osteosynthesis in the Treatment of Humeral Shaft Fractures: A Meta-Analysis

Background: Whether minimally invasive plating osteosynthesis (MIPO) or other operative interventions is superior in the treatment of humeral shaft fractures remains controversial. Therefore, we conducted a meta-analysis to quantitatively compare the clinical outcomes of MIPO and other operative interventions in the treatment of humeral shaft fractures. Methods: Pubmed, Embase, and Web of Science were systematically searched to identify all available studies comparing clinical outcomes between patients receiving MIPO and other operative interventions. The weight mean difference (WMD) was pooled to compare the operative time, union time, University of California, Los Angeles (UCLA) score, and Mayo elbow performance index (MEPI).The risk ratio (RR) was pooled to compare the union rate, and incidence of complications. Pooled estimates were calculated by using a fixed-effects model or a randomized-effects model, according to the heterogeneity among studies. Results: Nine studies were included in this meta-analysis. Our results suggest that both MIPO and other operative interventions can achieve similar union time, UCLA score, MEPI, and union rate. However, MIPO is associated with better outcomes including shorter operation time, and lower incidence of radial nerve injury. Conclusion: Evidence from this meta-analysis demonstrated that, MIPO is effective but safer than other operative interventions in the treatment of humeral shaft fracture. However, due to the potential limitations in this meta-analysis, randomized controlled trials with larger sample sizes using appropriate blinding methods are needed to confirm these findings.

Minimally invasive plate osteosynthesis for humeral shaft fractures: are results reproducible?

Minimally invasive plate osteosynthesis (MIPO) has been advocated as a safe approach to humeral shaft fracture management. We evaluated the reproducibility of this technique in a regional hospital. Thirty-five patients underwent MIPO of humerus shaft fractures. Fifteen patients had an open fracture, six a preoperative radial nerve palsy, and nine a concomitant thoracic, musculoskeletal or vascular injury. At an average 12-month follow-up, 91% of fractures healed after a mean of 12 weeks (range, 8–16). Two infections occurred. Final alignment averaged 4° of varus (range, 5° of valgus to 20° of varus). Active elbow ROM averaged 114° (range, 60–135°) and was less than 100° in nine elbows. Five of six preoperative radial nerve injuries recovered spontaneously. Healing and infection rates in this study are consistent with those reported in the literature. Lower elbow ROM and higher fracture angulation at healing were nevertheless found. MIPO is technically demanding and requires adequate intraoperative imaging and surgical experience in order to obtain adequate fracture alignment. Brachialis muscle scarring and inadequate postoperative rehabilitation may be involved in limited elbow range of motion.     

Functional treatment of the distal third humeral shaft fractures

OBJECTIVE: The objective of the present study was to determine the effectiveness of functional treatment for distal third humeral shaft fractures in young adults. PATIENTS AND METHODS: A custom-made prefabricated brace was applied for the functional treatment of 21 isolated, closed, distal third humeral shaft fractures of 21 patients (17 male and 4 female). Their average age was 25 years (range 18-37 years). The mean follow-up period was 39 weeks. RESULTS: All of the fractures united. The average time to union was 12 weeks. The average varus angulation was 7.8 deg in 8 patients, and the average shortening of the fractured limb was 10 mm in 4 patients. Minimal motion restrictions mostly occurred in shoulder abduction and lateral rotation. No patient showed a lack of elbow motion. Angulatory deformities and shortening had no effect on the functional outcome. None of the patients suffered radial nerve palsy during the course of treatment or due to entrapment in the callus of the healed fracture. CONCLUSIONS: Young adults who have isolated, closed, distal third humeral shaft fractures are good candidates for functional bracing.

Randomized prospective study of humeral shaft fracture fixation: intramedullary nails versus plates

OBJECTIVES: To compare the clinical and radiographic results for locked intramedullary (IM) nails and plates used in the treatment of humeral diaphyseal fractures. DESIGN: Prospective randomization by sealed-envelope technique of eighty-four patients into two study groups: those treated by intramedullary nailing (IMN group; n = 38) and those treated by compression plating (PLT group; n = 46). SETTING: Patients admitted consecutively to a university-affiliated Level I trauma center. PATIENT/PARTICIPANTS: All skeletally mature patients admitted to Harborview Medical Center with acute humeral shaft fractures requiring surgical stabilization. Fractures of the diaphysis were defined as being at least three centimeters distal to the surgical neck and at least five centimeters proximal to the olecranon fossa. INTERVENTION: Treatment with locking antegrade intramedullary humeral nails (Russell-Taylor design [Smith and Nephew Richards]) or with 4.5-millimeter dynamic compression and limited contact dynamic compression plates (AO design [Synthes]). MAIN OUTCOME MEASUREMENTS: Clinical outcome measurements included fracture healing, radial nerve recovery, infection, and elbow and shoulder discomfort. Radiographic measurements included fracture alignment, time to healing, delayed union, and nonunion. RESULTS: Follow-up averaged thirteen months. Forty-two fractures (93 percent) in the PLT group were healed by sixteen weeks versus thirty-three fractures (87 percent) in the IMN group (p = 0.70). Shoulder pain and a decrement in shoulder range of motion (ROM) were significant associations with IMN (p = 0.007 for both variables) but not with PLT. A decrement in elbow ROM was significantly associated with PLT (p = 0.03), especially for fractures of the distal third of the diaphysis, whereas elbow pain was not (p = 0.123). The sum of other complications demonstrated nearly equal prevalence for both treatment groups. CONCLUSIONS: For patients requiring surgical treatment of a humeral shaft fracture, intramedullary nailing and compression plating both provide predictable methods for achieving fracture stabilization and ultimate healing.

背景：由于术中广泛剥离、牵拉骨折周围软组织、影响骨折端血供,传统接骨板在治疗肱骨骨折有较高的骨不连发生率和医源性神经损伤发生率。 目的：探讨前方入路联合微创经皮接骨板内固定（MIPO）技术治疗肱骨干骨折的有效性和安全性。 方法：回顾性分析2010年1月至2012年12月收治的77例肱骨干骨折患者的临床资料。根据治疗方法分为MIPO组和对照组。MIPO组采用微创经皮接骨板置入技术进行骨折固定,对照组采用传统的切开复位内固定技术进行骨折固定。对两组患者的手术情况和术后功能恢复进行比较。 结果：两组患者手术顺利,MIPO组手术时间比对照组稍长,住院时间比对照组稍短,但两组间差异无统计学意义（P＞0.05）。MIPO组术中失血量、骨折愈合时间均显著少于对照组（P＜0.05）。末次随访时,MIPO组的肩、肘关节活动度和DASH评分均显著优于对照组（P＜0.05）。两组患者术后均无严重并发症发生。 结论：采用MIPO技术治疗肱骨干骨折具有微创、固定牢靠、并发症少、术后功能恢复迅速且良好等优点,应在肱骨干骨折治疗中推广使用。
