Plating of humeral shaft fractures--has the pendulum swung back?

Novel calcaneal plate versus traditional philos plate for treating split fractures of humeral greater tuberosity

Purpose

To compare the effect of two internal fixation methods of calcaneal plate fixation and Philos plate fixation in treating split fractures of humeral greater tuberosity.

Patients and methods

A total of 37 patients with split fractures of humeral greater tuberosity were retrospectively analyzed from September 2016 to April 2021. Enrolled patients were divided into Group A (calcaneal anatomical locking plates), and Group B [Proximal Humeral Internal Locking System (PHILOS)]. The demographics, injury-related variables, surgery-related variables, Constant-Murley score, and postoperative complication between the two groups were compared.

Results

There were 16 in Group A and 21 in Group B. Fracture union was achieved in all patients, with an average of 11.9 months. The mean length of incision was significantly different between groups (Group A, 6.16 cm ± 1.07 cm; Group B, 9.09 cm ± 1.30 cm, p < 0.05). Significant difference was observed by comparing bleeding loss between Group A and Group B (Group A, 45.41 ± 11.19 ml; Group B, 106.06 ± 11.12 ml, p < 0.05). After 6 months of treatment, the average Constant-Murley score of Group A was significantly higher than that of Group B (p < 0.05). In terms of operation, no significant difference was observed between groups. In addition, two patients had shoulder impingement syndrome in Group B, and none in Group A.

Conclusion

Calcaneal anatomical locking plate fixation is superior to Philos plate fixation in surgical trauma and bleeding loss. Our study provides an alternative technique for treating split fractures of humeral greater tuberosity.

Humeral shaft fracture: systematic review of non-operative and operative treatment

INTRODUCTION

Humeral shaft fractures can be treated non-operatively or operatively. The optimal management is subject to debate. The aim was to compare non-operative and operative treatment of a humeral shaft fracture in terms of fracture healing, complications, and functional outcome.

METHODS

Databases of Embase, Medline ALL, Web-of-Science Core Collection, and the Cochrane Central Register of Controlled Trials (CENTRAL) were systematically searched for publications reporting clinical and functional outcomes of humeral shaft fractures after non-operative treatment with a functional brace or operative treatment by intramedullary nailing (IMN; antegrade or retrograde) or plate osteosynthesis (open plating or minimally invasive). A pooled analysis of the results was performed using MedCalc.

RESULTS

A total of 173 studies, describing 11,868 patients, were included. The fracture healing rate for the non-operative group was 89% (95% confidence interval (CI) 84-92%), 94% (95% CI 92-95%) for the IMN group and 96% (95% CI 95-97%) for the plating group. The rate of secondary radial nerve palsies was 1% in patients treated non-operatively, 3% in the IMN, and 6% in the plating group. Intraoperative complications and implant failures occurred more frequently in the IMN group than in the plating group. The DASH score was the lowest (7/100; 95% CI 1-13) in the minimally invasive plate osteosynthesis group. The Constant-Murley and UCLA shoulder score were the highest [93/100 (95% CI 92-95) and 33/35 (95% CI 32-33), respectively] in the plating group.

CONCLUSION

This study suggests that even though all treatment modalities result in satisfactory outcomes, operative treatment is associated with the most favorable results. Disregarding secondary radial nerve palsy, specifically plate osteosynthesis seems to result in the highest fracture healing rates, least complications, and best functional outcomes compared with the other treatment modalities.

Humeral shaft fractures: a cost-effectiveness analysis of operative versus nonoperative management

BACKGROUND

Humeral shaft fractures can be managed operatively or nonoperatively with functional bracing in the absence of neurovascular injury, open fracture, or polytrauma. A consensus on optimal management has not been reached, nor has the cost-effectiveness perspective been investigated.

METHODS

A decision tree was constructed describing the management of humeral shaft fractures with open reduction-internal fixation (ORIF), intramedullary nailing (IMN), and functional bracing in a non-elderly population. Probabilities were defined using weighted averages determined from systematic review of the literature. Cost-effectiveness was evaluated with incremental cost-effectiveness ratios, measured in cost per quality-adjusted life-year (QALY). Willingness-to-pay thresholds of $50,000/QALY and $100,000/QALY were evaluated.

RESULTS

Eighty-six studies were included. Using bracing as the referent in the health care model, we observed that bracing was the preferred strategy at both incremental cost-effectiveness ratio thresholds. ORIF and IMN had higher overall effectiveness (0.917 QALYs and 0.913 QALYs, respectively) compared with bracing (0.877 QALYs). The cost-effectiveness of bracing was driven by a substantially lower overall cost. In the societal model-accounting for both health care and societal costs-the cost difference narrowed between bracing, ORIF, and IMN. Bracing remained the preferred strategy at the $50,000/QALY threshold; ORIF was preferred at the $100,000/QALY threshold. ORIF and IMN were comparable strategies across a range of probability values in sensitivity analyses.

CONCLUSIONS

Functional bracing, with its low cost and satisfactory clinical outcomes, is often the most cost-effective strategy for humeral shaft fracture management. ORIF becomes preferable at the higher willingness-to-pay threshold when societal burden is considered. QALY values for ORIF and IMN were comparable.

Ultrasound-guided preoperative localization of radial nerve in the treatment of extra-articular distal humeral shaft fractures

Background

The aim of this study was to discuss the treatment of extra-articular distal humeral shaft fractures using ultrasound-guided preoperative localization of radial nerve.

Methods

Between May 2010 and December 2019, 56 patients with extra-articular distal humeral shaft fractures were retrospectively reviewed. Twenty eight patients were received examination by using preoperative localization of radial nerve guided by ultrasound-guided preoperative localization (group A) and 28 control patients without ultrasound-guided (group B). All patients were treated surgically for distal humeral shaft fractures by posterior approach techniques. Operative time, radial nerve exposure time, intraoperative bleeding volume, union time and iatrogenic radial nerve palsy rate were compared between the two groups. Elbow function was also evaluated using the Mayo Elbow Performance Score (MEPS).

Results

A significant difference was observed between the two groups, Operative time (113.25 min vs 135.86 min) (P < 0.001), radial nerve exposure time (20.82 min vs 32.53 min) (P < 0.001), intraoperative bleeding volume (246.80 ml vs 335.52 ml) (P < 0.001). However, iatrogenic radial nerve palsy rate (3.6% vs 7.1%) (P = 0.129), the fracture union time (13.52 months vs 12.96 months) (P = 0.796) and the MEPS score (87.56 vs 86.38) (P = 0.594) were no significantly different in both groups.

Conclusions

The study demonstrates that ultrasound-guided preoperative localization is an effective approach in the treatment of extra-articular distal humeral shaft fracture by revealing radial nerve, which may help reduce the operative time, radial nerve exposure time and the intraoperative bleeding volume.

Anterior Minimally Invasive Plate Osteosynthesis for Humeral Shaft Fractures Is Safer Than Open Reduction Internal Fixation: A Matched Case-Controlled Comparison

OBJECTIVE

Compare anterior minimally invasive plate osteosynthesis (MIPO) to open reduction/internal fixation (ORIF) for humeral shaft fractures, assessing complications and clinical outcomes.

DESIGN

Retrospective matched case-controlled cohort.

SETTING

Tertiary referral trauma centre.

PATIENTS/PARTICIPANTS

Humeral shaft fractures identified retrospectively over 5 years; 31 were treated by MIPO and 54 by ORIF. Matched-case cohort assembled according to fracture pattern, sex, age, and comorbidities, with 56 total patients (28 per group).

INTERVENTIONS

MIPO and ORIF.

MAIN OUTCOME MEASURES

Complication rate was the primary outcome (radial nerve injury, nonunion, infection, and reoperation). Radiographic alignment and the Disabilities of the Arm, Shoulder and Hand Score were secondary outcomes.

RESULTS

Cumulative complication rates were 3.6% after anterior MIPO and 35.7% after ORIF (P = 0.0004). The only complication after anterior MIPO was a nonunion, managed with revision ORIF and bone graft. The ORIF group had 10 complications, including 5 superficial infections, 4 iatrogenic radial nerve injuries, and 1 nonunion. The mean Disabilities of the Arm, Shoulder and Hand score after MIPO was 17.0 ± 18.0 and after ORIF was 24.9 ± 19.5. The mean coronal plane angulation after MIPO was 1.8 ± 1.3 degrees and after ORIF was 1.0 ± 1.2 degrees. The mean sagittal plane angulation after MIPO was 3.0 ± 2.9 degrees and after ORIF was 1.0 ± 1.2 degrees.

CONCLUSIONS

The cumulative complication rate was 10 times higher after ORIF of humeral shaft fractures compared with the MIPO technique. MIPO achieved nearly equivalent radiographic alignment, with no clinically meaningful differences observed. MIPO is the safer option and should be considered for patients with humeral shaft fractures that would benefit from surgical intervention.

Stabilisation of pathological humerus fractures using cement augmented plating: A case series

The humerus is the second most common long bone for metastatic tumours. These lesions result in weakened bone architecture and increased fracture risk with patients suffering pain, loss of function and diminished quality of life, often when life expectancy is short. Fractures or impending fractures require surgical stabilisation to relieve pain and restore function for the remainder of the patient's life without the need for further surgery. Conventional management of these lesions in the humerus is intramedullary nailing, however there are issues with this technique, particularly regarding rigidity of fixation. Advances in contoured locking plates have led to the development of different stabilisation techniques. The preferred technique in our regional oncology unit is curettage of the tumour and plating, augmented with cement to fill the defect and restore the structural morphology. In this case series we evaluate the survivorship of the construct and the clinical outcomes in patients who had an established or prospective pathological humeral fracture treated with curettage and cement augmented plating, since 2010. We identified 19 patients; 17 had metastasis and 2 myeloma of whom 15 had established fractures and four impending. The mean age at surgery was 69 years (51-86), and mean time since surgery 3.2 years. Overall mean follow up time was 20 months with 14 patients deceased and 5 surviving. There was 100% survivorship of the construct with no mechanical failures and no re-operations. There were no post-operative wound complications. Excellent early pain control was achieved in 18 patients with one experiencing pain controlled by analgesia. Function was assessed using Toronto Extremity Salvage Score (TESS) and was satisfactory; mean 79/100 (range 72-85). Cement augmented plating for pathological humerus fractures is a suitable alternative to intramedullary nailing and addresses several of the concerns with that technique. It provides immediate rigidity and allows early unrestricted function.

Humeral shaft fractures

Humeral shaft fractures are relatively common, representing approximately 1% to 5% of all fractures.

Conservative management is the treatment of choice for most humeral shaft fractures and offers functional results and union rates that are not inferior to surgical management.

Age and oblique fractures of the proximal third are risk factors for nonunion. Surgical indication threshold should be lower in patients older than 55 years presenting with this type of fracture.

Functional outcomes and union rates after plating and intramedullary nailing are comparable, but the likelihood of shoulder complications is higher with intramedullary nailing.

There is no advantage to early exploration of the radial nerve even in secondary radial nerve palsy.

Comparison of the Posterior and Anterolateral Surgical Approaches in the Treatment of Humeral Mid-Shaft Fractures: A Retrospective Study

Background

The aim of this study was to retrospectively assess and compare the functional outcomes and complications following anterolateral versus posterior surgical approaches for the treatment of mid-shaft fractures of the humerus.

Material/Methods

This study included 107 patients treated for mid-shaft fractures between May 2015 and July 2018. Demographic and surgical data were collected for each patient. During follow-up visits, radiographs were acquired and evaluated. The clinical outcomes of the involved joints were assessed by the Constant scoring system, range of motion (ROM), and the Mayo Elbow Performance Scoring system at the 12-month follow-up.

Results

The posterior approach was performed in 57 patients with type A fractures (group I, n=28) and type B or C fractures (group III, n=29). The anterolateral approach was performed in 50 patients with type A fractures (group II, n=32) and type B or C fractures (group IV, n=18). There were no significant differences between group I and group II nor between group III and group IV with respect to patient demographic data, surgical data, Constant score, ROM, or Mayo Elbow Performance score. A significant difference in the total complication rate was observed between group I and II.

Conclusions

The anterolateral approach showed an advantage over the posterior approach for treating simple humeral mid-shaft fractures. However, this advantage was not observed in treating comminuted fractures.

Humeral shaft fracture: a randomized controlled trial of nonoperative versus operative management (plate fixation)

Purpose

This randomized controlled trial was conducted to investigate the outcomes of humeral shaft–fracture management with the functional Sarmiento brace (nonoperative) versus open reduction internal fixation (ORIF).

Methods

Sixty humeral shaft–fracture patients with a minimum age of 18 years were randomly assigned into two groups: operative treatment with open reduction–internal fixation (ORIF) or functional brace (Sarmiento). A similar postoperative rehabilitation program was applied for all subjects for the next 12 months. The outcomes of each method were measured in terms of nonunion rate, union time, “quick” Disabilities of Arm, Shoulder, and Hand (DASH) questionnaire scores, and rate of complications, such as malunion, infection, and radial nerve injury.

Results

The two groups had similar baseline characteristics, including age, sex, smoking status, and type and mechanism of fracture. The mean union time was about 4.8 weeks shorter in the ORIF group (13.9 weeks in operative group versus 18.7 weeks in nonoperative group), indicating a definite significant superiority (p=0.001) of ORIF management to functional Sarmiento bracing. However, a comparison of quick DASH scores revealed a borderline-significant difference between the groups (p=0.065). Additionally, we found that treatment of humeral shaft fractures using functional bracing was associated with slightly higher risk of nonunion; however this was not significant (p=0.492).

Conclusion

According to the present findings, there is remarkable superiority of ORIF over functional Sarmiento bracing in the management of patients with humeral shaft fracture.

Displaced isolated greater tuberosity fractures of elder adults treated with plate osteosynthesis

BACKGROUND

We elucidated the effect of open reduction and internal fixation with locking plate for acute isolated displaced greater tuberosity fractures of humerus in elder adults (aged >60 years).

METHODS

From 2009 to 2015, data from 32 patients, aged between 60 and 88 years, who had acute unilaterally displaced greater tuberosity fractures of humerus were collected and evaluated retrospectively. All the fractures were managed with open reduction and internal fixation with locking plate. The follow-up period was 50.8 months on an average (range 22-80 months). Finally, 25 patients were available for final evaluation of radiographic and functional results.

RESULTS

All the 32 fractures had union with the average union time of 14 weeks (range 10-18 weeks) and with no complications. The average of preoperative Visual Analogue Scale (VAS) was 6.2 (range 4-8), ASES was 30.4 (range 13-45), and Constant score was 30.4 (range 20-45). At the last follow-up, the mean VAS was 1.3 (range 0-2.5), the mean ASES score was 90.1 (range 72-100), and the mean Constant score was 90.3 (range 80-100). There were statistically significant differences between preoperative and final follow-up in VAS, ASES, and Constant score. Hundred percent of patients had good or excellent results by Constant score, with excellent results (86-100) in 17 (68%) patients and good result (71-85) in 8 (32%).

CONCLUSION

In conclusion, open reduction and internal fixation with locking plate is an effective treatment for acute displaced greater tuberosity fractures of humerus in elder adults.

Proximal third humeral shaft fractures fixed with long helical PHILOS plates in elderly patients: benefit of pre-contouring plates on a 3D-printed model-a retrospective study

BACKGROUND

To explore the clinical efficacy of 3D printing fracture models to assist in creating pre-contoured plates to treat proximal third humeral shaft fractures.

METHODS

We retrospectively identified proximal third humeral shaft fractures treated between February 2012 and February 2015. The patients were divided into two groups according to the treatment procedure: a Synbone group and a 3D-printed group. In the Synbone group, long proximal humeral internal locking system plates were pre-contoured into helical shape on Synbones before surgery, while in the 3D-printed group, they were contoured on 3D-printed bone models. The pre-contoured plates were sterilized before surgery and were then used for fracture fixation during surgery. Duration of surgeries, blood loss volumes, the incidence of complications, and the time to fracture union were recorded, and functional outcomes were assessed by the Constant-Murley shoulder score and the Mayo Elbow Performance Score (MEPS) at 1-year follow-up.

RESULTS

The subjects comprised 46 patients; 25 patients were allocated to the Synbone group and the remaining 21 to the 3D-printed group. There was no significant difference between the baseline characteristics of the two groups. At the 1-year follow-up visit, all fractures were healed and showed a satisfactory outcome. There were no instances of iatrogenic radial nerve injury, and there was no significant difference between the two groups with regard to fracture union time, Constant-Murley score, or MEPS score. Surgery duration was significantly shorter in the 3D-printed group compared to the Synbone group (42.62 vs. 60.36 min, P = 0.001), and the 3D-printed group lost less blood during surgery (105.19 vs. 120.80 ml, P = 0.001). In addition, in the 3D-printed group, 9 surgeries were finished by senior attending doctors and 12 were finished by junior attending doctors; however, there was no significant difference between the 1-year outcomes of the two grades of surgeons.

CONCLUSIONS

Our results show that the 3D printing technique is helpful in shortening the duration of surgery, reducing blood loss volume, and in making this surgical procedure easier for less-experienced surgeons.

Innovative Techniques for Maximizing Limb Salvage and Function

Concurrent injuries to multiple extremities present unique challenges to the reconstructive surgeon. The primary goal in such scenarios is to optimize functional outcomes. The goal of this article is to present an overview of various techniques necessary to provide sufficient soft tissue and preserve amputation limb lengths and function. The concept of innovative techniques for maximizing limb savage and function is presented using an index patient with multiple extremity third- and fourth-degree burn injuries resulting in nonsalvageable lower extremities and severe left-hand wounds. A review of other potential innovative techniques is discussed. The burn injury resulted in a need for bilateral guillotine below-knee amputations. Above-knee amputation was avoided in the left leg using a parascapular free fasciocutaneous flap, while through-knee amputation was preferred to above-knee amputation in the right leg. The preservation of areas with questionable viability resulted in salvaging the left hand of the patient using digital palmar flaps to resurface the dorsum with creation of a first web-space. Maintenance of maximal viable length of limbs and any residual function in the limbs can be of significant functional benefit to multiple limb amputation patients. Maximizing the limb length in such patients is critical, and typical "rules" that have traditionally been utilized to minimize numbers of operations and optimize prosthetic fit may not apply.

Time From Injury to Surgical Fixation of Diaphyseal Humerus Fractures Is Not Associated With an Increased Risk of Iatrogenic Radial Nerve Palsy

OBJECTIVES

To determine whether time from injury to fixation of diaphyseal humeral fractures and nonunions is associated with the risk of iatrogenic radial nerve palsy.

DESIGN

Retrospective review.

SETTING

Two Level 1 trauma centers.

PATIENTS/PARTICIPANTS

Between 2001 and 2015, 325 patients who had documented intact radial nerve function preoperatively were treated with fixation of a humerus fracture or humerus nonunion.

INTERVENTION

Open reduction and internal fixation.

MAIN OUTCOME MEASUREMENTS

Development of an iatrogenic radial nerve injury. Those with an injury were followed to either resolution of the nerve palsy or definitive treatment.

RESULTS

The risk of iatrogenic radial nerve palsy was 7.7% (25/325). Time to surgery was not significantly associated with iatrogenic radial nerve palsy. In a multiple variable analysis, when comparing patients treated within 4 weeks to those treated 4-8 weeks (P = 0.41), 8-12 weeks (P = 0.94), and over 12 weeks (0.20), there were no significant associations. Independent risk factors for iatrogenic radial nerve palsy included distal location of fracture (P = 0.04, odds ratio 3.71) and previous fixation (P = 0.03, odds ratio 3.80). Of the 25 iatrogenic nerve injuries, 22 recovered fully with expectant management, 1 was lost to follow-up, and 2 required either nerve graft or tendon transfers.

CONCLUSIONS

Time from injury to surgery does not seem to be a risk factor for developing an iatrogenic radial nerve palsy when treating diaphyseal humerus fractures. Patients with distal fractures, and those with previous fracture implants, are at increased risk of iatrogenic radial nerve palsy.

Comparison between antegrade intramedullary nailing (IMN), open reduction plate osteosynthesis (ORPO) and minimally invasive plate osteosynthesis (MIPO) in treatment of humerus diaphyseal fractures

INTRODUCTION

The three currently used methods of treatment: namely open reduction plate osteosynthesis (ORPO), Minimally invasive plate osteosynthesis (MIPO), antegrade intramedullary nailing(IMN) are all reported as satisfactory procedures for treatment of humeral shaft fractures. However none of the published reports have a comparison of superiority of one procedure over the other. We evaluated the clinical, radiological and functional outcome of the three procedures.

MATERIALS AND METHODS

We studied adult patients with humerus shaft fractures over a period of 2 years from May 2014 to May 2016 in a level 1 trauma center. Forty-four were treated with IMN, 34 treated with ORPO, and 34 with MIPO. The null hypothesis tested in this study is that there is no difference between IMN, ORPO, MIPO with respect to union time, surgical time, complication rate, non-union rate and functional outcome. Functional outcome was studied by comparing the UCLA shoulder and MEP scores in the three groups.

RESULTS

112 patients were studied consisting of 83 males and 29 females with mean age of 39 years (range 18-70). IMN group showed early union with mean of 12.73 weeks compared to MIPO (14.45 weeks) and ORPO(13.58 weeks), (p<0.05). MIPO had no events of non-union, as compared to ORPO (5 non-unions) and IMN (10 non-unions), (p=0.04). The range of movement at the shoulder with the UCLA score was significantly better with a score of 32.26 in MIPO as compared to 27.54 in IMN and 28.82 in ORPO (p<0.05). The difference in MEPS score in the three groups was not significant (p=0.31). IMN required a mean of 117.95 minutes intraoperatively as compared to 131 and 150.58 mins in MIPO, ORPO respectively.

CONCLUSION

MIPO is overall better with respect to non-union, functional outcome and complications rate. The surgical time depends on the surgeons' skill and learning curve. Thus considering the advantages and risks involved in the various procedure and surgical acumen, each case should be individualized to have a good outcome. We advocate that MIPO can be safely used as an alternative in treating these fractures.

Management of Closed Diaphyseal Humerus Fractures in Patients With Injury Severity Score ≥17

OBJECTIVES

The management of closed diaphyseal humerus fractures in the polytrauma patient varies widely. The aim of this study was to compare outcomes of operative and nonoperative management in this patient population.

DESIGN

Single-center, retrospective cohort analysis.

SETTING

Urban, Level 1 trauma center.

PATIENTS

Seventy-one patients with closed diaphyseal humerus fractures, and Injury Severity Score (ISS) of ≥17, treated between 2006 and 2011 were identified.

INTERVENTION

Patients were treated operatively versus nonoperatively with a functional brace by surgeon preference.

MAIN OUTCOMES

Primary outcome was union. Secondary outcomes included time to union, time to release to weightbearing, and complications other than nonunion.

RESULTS

There was no statistical difference between age, Injury Severity Score, or fracture type between the 2 cohorts. There was a statistically higher incidence of associated orthopaedic injury, and more specifically, lower extremity injury in the group treated with operative intervention. There was no difference in union rates (95% operative, 94% nonoperative), time to union (17 weeks operative, 15 weeks nonoperative), or complication rates between the 2 groups. Time to release to weightbearing was 3 weeks shorter in the operative group (9.3 weeks operative, 12.8 weeks nonoperative).

CONCLUSIONS

Polytrauma patients with closed diaphyseal humerus fractures can be treated successfully with equivalent union rates, time to union, and complication rates when selected for conservative management techniques. The decision to undertake operative management of closed diaphyseal humerus fractures in the polytraumatized patient is multifaceted and should consider patient expectations, demographics, injury profile, and ambulatory status.

Comparison of the effect on bone healing process of different implants used in minimally invasive plate osteosynthesis: limited contact dynamic compression plate versus locking compression plate

Minimally invasive plate osteosynthesis (MIPO) has been widely accepted because of its satisfactory clinical outcomes. However, the implant construct that works best for MIPO remains controversial. Different plate designs result in different influence mechanisms to blood flow. In this study, we created ulnar fractures in 42 beagle dogs and fixed the fractures using MIPO. The dogs were randomly divided into two groups and were fixed with a limited contact dynamic compression plate (LC-DCP) or a locking compression plate (LCP). Our study showed that with MIPO, there was no significant difference between the LCP and the LC-DCP in terms of fracture fixation, bone formation, or mineralization. Combined with the previous literature, we inferred that the healing process is affected by the quality of fracture reduction more than plate selection.

Minimally invasive plating versus either open reduction and plate fixation or intramedullary nailing of humeral shaft fractures: a systematic review and meta-analysis of randomized controlled trials

HYPOTHESIS

The purpose of this study was to perform a meta-analysis comparing the clinical outcomes and complications between anterior humeral minimally invasive plate osteosynthesis (MIPO) and the 2 standard techniques, either open reduction and plating or humeral nailing.

METHODS

We performed a systematic review of Medline, Embase, Scopus, and Google Scholar to identify relevant randomized controlled trials in the English- and German-language literature. Eligibility criteria included randomized controlled trials comparing at least 1 surgical intervention with MIPO and reporting the primary clinical outcome using a validated functional scoring system and description of complications. Publication bias was assessed by funnel plot, and the risk of bias was established using the Cochrane Collaboration's Risk of Bias Tool. Heterogeneity was assessed using χ(2) and I(2) statistics.

RESULTS

Eight prospective randomized studies (N = 376) met the eligibility criteria and were included in the analysis. The pooled estimate for clinical outcome showed that MIPO resulted in a significantly better outcome (standardized mean difference, 0.366; 95% confidence interval, 0.16 to 0.571; P = .0001; I(2) = 61%). The pooled estimate for all complications showed that the open reduction-internal fixation/nail group had a significantly higher complication rate (odds ratio, 0.507; 95% confidence interval, 0.285 to 0.905; P = .021; I(2) = 97%).

CONCLUSION

Current evidence indicates the MIPO approach has better clinical outcomes with a lower rate of complications compared with alternative surgical techniques. However, the results of this meta-analysis are limited by problems inherent in the primary studies, including poor reporting of randomization protocols, as well as possible attrition bias and reporting bias, of the primary studies. Future publications may therefore change the trend of the pooled estimate in either direction.

Humeral Shaft Fracture Fixation: Incidence Rates and Complications as Reported by American Board of Orthopaedic Surgery Part II Candidates

BACKGROUND

Despite extensive research regarding patient outcomes after operative fixation of humeral shaft fractures by means of open reduction and internal fixation (ORIF) or intramedullary nailing (IMN), no current consensus exists regarding the optimal surgical treatment. The objective of this study was to compare IMN and plate fixation (ORIF) of humeral shaft fractures by using the American Board of Orthopaedic Surgery (ABOS) Part II operative database to analyze incidence rates, changes in management trends over time, early complications, and factors affecting the management choice.

METHODS

The ABOS database is a collection of surgical cases that are self-reported by orthopaedic candidates approved for admission to the ABOS oral examination. The database was searched for records from 2004 to 2013 for humeral shaft surgical cases as indicated by Current Procedural Terminology (CPT) codes 24515 (open reduction internal fixation) and 24516 (insertion of intramedullary nail) pertaining to humeral shaft fractures. The geographic region and fellowship training of the candidates; the year of surgery, diagnosis code, age, and sex of the patients; and the surgeon-reported complications were analyzed.

RESULTS

The search identified 3,430 surgically treated humeral shaft fractures that were reported to the ABOS database from 2004 to 2013. A significant decline in IMN use was seen from 2004 (42.9%) to 2013 (21.2%, p < 0.001). The IMN cohort had lower complication rates pertaining to both infections (1.5% compared with 3.0% for ORIF, p = 0.007) and nerve palsies (3.1% compared with 7.8%, p < 0.001). No significant difference was seen in the rate of nonunion (1.3% for IMN compared with 1.6% for ORIF, p = 0.63), although follow-up may be too short to demonstrate a difference. The IMN cohort did have significantly higher mortality (4.9% compared with 0.7% for ORIF, p < 0.001). Subset analysis demonstrated that the IMN cohort had significantly more pathologic fractures (26.8% compared with 1.5% of the fractures treated with ORIF, p < 0.001).

CONCLUSIONS

Although the overall incidence of fixation of humeral shaft fractures was unchanged from 2004 to 2013, there was a significant shift from IMN to ORIF using plate fixation during this time period. Possible reasons for this shift in treatment to ORIF include the potential impact of recent publications highlighting complications of IMN and increased surgeon attention to cost containment.

A Retrospective Study in the Treatment of a 2-Part Greater Tuberosity Fracture Using the F3 Biomet Plate

The purpose of this study was to evaluate the clinical efficacy of the F3 Biomet plate in the treatment of 2-part displaced humeral greater tuberosity fractures. We compared the clinical outcomes of patients with displaced greater tuberosity fractures who underwent surgical treatment using an F3 plate with those of patients who were treated nonsurgically. Eleven patients with 2-part displaced humeral greater tuberosity fractures were surgically treated with use of an F3 Biomet plate, whereas 12 patients with equal injuries were treated nonsurgically. Each patient underwent follow-up for at least 1 year. We retrospectively collected data and analyzed the clinical outcomes. The Constant score and DASH score were used to assess the shoulder function, and X-rays were taken to evaluate the fracture healing. X-rays of the patients in both groups showed that the fractures achieved union after the 1-year follow-up. Patients treated surgically with an F3 plate and open reduction internal fixation had better Constant score and DASH score results for shoulder function than those treated nonsurgically. In the present study, surgical treatment of displaced humeral greater tuberosity fractures with the use of an F3 plate led to a 100% union rate and good clinical outcomes. The F3 Biomet plate can be considered an effective implant for the treatment of displaced humeral greater tuberosity fractures. The level of evidence is therapeutic III.

Effects of different surgical techniques on mid-distal humeral shaft vascularity: open reduction and internal fixation versus minimally invasive plate osteosynthesis

Background

Humeral shaft fractures are generally managed with the conventional posterior open reduction and internal fixation (ORIF) or minimally invasive plate osteosynthesis (MIPO). This study was aimed at comparing the outcomes of these surgical techniques in terms of the vascular integrity of the mid-distal humeral shaft.

Methods

Twelve upper limbs were harvested from 6 fresh cadavers. ORIF or MIPO was randomly performed on either side of each pair of limbs. The axillary artery was perfused with a latex-lead tetraoxide red solution to visualize the vascular structures. The vascular integrity of the humerus was examined by plain radiography and dissection. The periosteal filling achieved with each technique was scored and the scores compared.

Results

In each limb, one main nutrient artery entering the mid-distal humeral shaft anteromedially (83.3 %) or medially (16.7 %) was first identified. No case of injury to the main nutrient artery was noted for either surgical technique. Injuries to the accessory nutrient arteries entering the mid-distal humeral shaft from the posterior aspect were absent in the MIPO cases, but occurred in 52.9 % of the ORIF cases. In addition, MIPO was also superior to the open plate technique showed superior periosteal filling than.

Conclusions

Our results showed that the MIPO technique is superior to the ORIF in terms of preserving the vascular integrity of the mid-distal humeral shaft.

Medial approach to treat humeral mid-shaft fractures: a retrospective study

Background

Plate fixation is the gold standard for diaphyseal fracture management, and the anterolateral approach is widely used by reconstructive surgeons. However, the outcomes of humeral shaft fracture fixation using a medial approach are rarely reported. The aim of this study is to explore the management and outcomes of humeral mid-shaft fractures fixed through a medial incision.

Methods

Thirty-four patients who sustained a humeral mid-shaft fracture and underwent an open-reduction internal fixation (ORIF) in our department between January 2010 and January 2013 were included in this study. Sixteen patients had an ORIF performed through a medial approach, while the remaining 18 were fixed through an anterolateral approach. Postoperative clinical and radiographic results were reviewed.

Results

There were no significant differences in the blood loss and the range of motion of the shoulder and elbow between the anterolateral and medial fixation groups. One patient in the medial group and two patients in the anterolateral group had radial nerve dysfunction that improved after 8, 3 and 6 weeks, respectively. All patients healed radiographically except one from the anterolateral group who underwent grafting and re-fixation for a non-union. No vascular injuries, infections, malunions, broken plates or loose screws were noted in either group.

Conclusions

The medial approach to the humerus had equivalent outcomes to anterolateral fixation. It is an available choice for humeral mid-shaft fracture fixation in cases where there is no need to expose the radial nerve. The medial approach does not require a pre-bent plate and creates a large operative exposure. A well-hidden incision can also be designed, improving cosmetic outcomes. However, the medial approach is not suitable to proximal or distal humerus fractures.

Newly designed minimally invasive plating of a humerus shaft fracture; a different introduction of the plate

PURPOSE

Open reductions and internal fixations are currently being used the most in surgeries of humeral shaft fractures. However, there are some limitations such as invasive techniques and formation of many operation scars. To overcome these limitations, a minimally invasive plate osteosynthesis has been recently introduced. However, this has technical limitations such as deep dissections of the distal portion and narrowness of the fixation space. To address these problems, we designed another introductory technique of a minimally invasive osteosynthesis and we have examined the clinical usefulness of that.

METHODS

The results were retrospectively analyzed with 83 patients who visited INHA hospital due to a humeral shaft fractures and who had undergone the above said surgery from the beginning of 2010 to the end of 2012. The patients were divided into two groups: patients treated by the MIPO technique using the newly designed dual approaches (group A) and patients treated by open reduction and plating internal fixation (group B).

RESULTS

There was no significant difference in mean duration of injury, the mean fracture union time, range of motion and MEPI for group A and B. There was no statistical significance between the two groups. However, the occurrence of iatrogenic radial nerve palsy in group B, was significantly higher than in group A.

CONCLUSIONS

MIPOs using the dual approaches on the adult humerus shaft fracture show an excellent bony union without nerve injury which is clinically useful.

Treatment of Humeral Shaft Fractures: Minimally Invasive Plate Osteosynthesis Versus Open Reduction and Internal Fixation

Background:

The optimal technique for operative fixation of humeral shaft fractures remains controversial and warrants research.

Objectives:

The purpose of the current study was to compare the functional and clinical outcomes of conventional open reduction and internal fixation (ORIF) with minimally invasive plate osteosynthesis (MIPO) in patients with fractures in two-third distal humeral shaft.

Patients and Methods:

In the current prospective case-control study, 65 patients with humeral shaft fractures were treated using ORIF (33 patients) or MIPO (32 patients). Time of surgery, time of union, incidence of varus deformity and complications were compared between the two groups. Also, the university of California-Los Angeles (UCLA) shoulder rating scale and Mayo Elbow performance score (MEPS) were used to compare the functional outcomes between the two groups.

Results:

The median of union time was shorter in the MIPO group (4 months versus 5 months). The time of surgery and functional outcomes based on the UCLA and MEPS scores were the same. The incidence of varus deformity was more than 5° and was higher and the incidence of nonunion, infection and iatrogenic radial nerve injury were lower in the MIPO group; however, the differences were not significant.

Conclusions:

Due to the shorter union time, to some extent less complication rate and comparable functional and clinical results, the authors recommend to use the MIPO technique in treating the mid-distal humeral shaft fracture.

Fracture union in closed interlocking nail in humeral shaft fractures

Background:

Fracture shaft humerus is a major cause of morbidity in patients with upper extremity injuries. The aim of this study was to evaluate the outcome of interlocking nail in humeral shaft fractures.

Methods:

This study was conducted in the Department of Orthopedic Surgery in SMS and R Sharda University from January 2010 to November 2013. Seventy-eight patients were recruited from emergency and out-patient department having a close fracture of humerus shaft. All patients were operated under general anesthesia and closed reamed interlocking nailing was done. All patients were followed for 9 months.

Results:

Out of 78 patients, 69 patients underwent union in 90–150 days with a mean of 110.68 days. Complications found in four patients who had nonunion, and five patients had delayed union, which was treated with bone grafting. All the patients were assessed clinically and radiologically for fracture healing, joint movements and implant failure. The results were excellent in 88.46% and good in 6.41% patients. Complete subjective, functional, and clinical recovery had occurred in almost 100% of the patients.

Conclusions:

The results of the present study indicates that in the presence of proper indications, reamed antegrade intramedullary interlocked nailing appears to be a method of choice for internal fixation of osteoporotic and pathologic fractures.

Comparison of lateral and posterior surgical approach in management of extra-articular distal humeral shaft fractures

OBJECTIVE

The objective of this study was to compare treatment results and complication rates between lateral and posterior approaches in surgical treatment of extra-articular distal humeral shaft fractures.

MATERIAL AND METHODS

Between June 2008 and May 2012, a total of 68 patients with extra-articular distal humeral shaft fractures were treated by lateral and posterior approaches. Of the patients, 30 were operated by a lateral approach (group I) and 26 patients were operated by a posterior approach (group II). There was no statistical significance between the two groups in sex distribution, age, the mechanism of the injury, injured arms, AO/ASIF (Arbeitsgemeinschaft für Osteosynthesefragen/Association for the Study of Internal Fixation) classification, and the time from injury to surgery (P>0.05). Operation time, intraoperative bleeding volume, hospitalisation, clinical outcomes, and complications were compared between the two groups. The elbow functional results were evaluated by the Mayo Elbow Performance Score (MEPS).

RESULTS

All patients were followed up. The average of follow-up in group I was 15.53±2.636 months (range, 12-22 months), and was 16.12±2.889 months (range, 12-22 months) in group II. There was no significant difference in the operation time, intraoperative bleeding time, and hospitalisation between the two groups (P>0.05). In group I, the mean time of bone union was 12.87±1.852 weeks (range, 10-16 weeks), the mean degrees of elbow flexion was 139.20°±3.274° (range, 134-146°), the mean degrees of elbow extension was 4.77°±1.906° (range, 0-8°), and the mean points of MEPS was 87.00±7.724 (range, 70-100 points). In group II, the mean time of bone union was 12.96±2.218 weeks (range, 10-16 weeks), the mean degrees of elbow flexion was 137.85°±4.076° (range, 130-145°), the mean degrees of elbow extension was 5.15°±2.327° (range, 0-9°), and the mean points of MEPS was 86.15±7.656 (range, 70-100 points). There was no significant difference in the bone union, range of elbow flexion, range of elbow extension and MEPS between the two groups (P>0.05). The overall complication rate in group I was lower than that in group II (P=0.041).

CONCLUSIONS

Both lateral and posterior surgical approaches acquired satisfied treatment results in the management of extra-articular distal humeral shaft fractures, and there was a lower complication rate using the lateral approach.

AO X-shaped midfoot locking plate to treat displaced isolated greater tuberosity fractures

Although various implants exist for 3- and 4-part fractures, few implants are appropriate for isolated greater tuberosity fractures. This retrospective study evaluated the efficacy of AO X-shaped midfoot locking plates for greater tuberosity fractures. Between May 2008 and September 2009, nineteen patients with displaced greater tuberosity fractures were treated with open reduction and internal fixation using AO X-shaped midfoot locking plates. Postoperatively, radiographs, functional results, and complications were evaluated. All patients were followed up for a mean 33.2 months (range, 24-42 months). Mean healing time was 9.4 weeks (range, 8-14 weeks). Mean Constant score was 90.6±4.0 points (range, 77-95 points). Excellent results were obtained in 16 cases, good in 2 cases, moderate in 1 case, and poor in 0 cases. The excellent-good rate was 94.7%. No recurrence of dislocation occurred in the 11 cases with shoulder dislocation. All fractures healed without the complications of wound infection, skin numbness, subacromial impingement syndrome, nonunion, secondary displacement, and implant loosening. The described technique is an effective, simple, and inexpensive method with a short learning curve.

Outcome of locking compression plates in humeral shaft nonunions

BACKGROUND

Nonunion of diaphyseal fractures of the humerus are frequently seen in clinical practice (incidence of up to 15% in certain studies) and osteosynthesis using dynamic compression plates, intra medullary nails and Ilizarov fixators have been reported previously. Locking compression plates (LCP) are useful in the presence of disuse osteoporosis, segmental bone loss and cortical defects that preclude strong fixation. We report a prospective followup study of the outcome of the use of LCP for humeral nonunion following failed internal fixation in which implants other than LCP had been used.

MATERIALS AND METHODS

Twenty four patients with nonunion of humeral shaft fractures following failed internal fixation were included in the study. The mean followup period was 3.4 years (range: 2.4 to 5.7 years) and the minimum followup period was 2 years. Mean age of the patients was 41.04 years (range: 24 to 57 years). All 24 patients underwent osteosynthesis using LCP and autologous bone grafting (cortico-cancellous iliac crest graft combined with or without fibular strut graft). Main outcome measurements included radiographic assessment of fracture union and pre and postoperative functional evaluation using the modified Constant and Murley scoring system.

RESULTS

23 out of 24 fractures united following osteosynthesis. Average time to union was 16 weeks (range: 10 to 28 weeks). Complications included delayed union (n = 2), transient radial nerve palsy (n = 2) and persistent nonunion (n = 1). Functional evaluation using the Constant and Murley score showed excellent results in 11, good in 10, fair in two and poor outcome in one patient.

CONCLUSIONS

Locking compression plating and cancellous bone grafting is a reliable option for achieving union in humeral diaphyseal nonunion with failed previous internal fixation and results in good functional outcome in patients with higher physiological demands.

Minimally invasive helical plating for shaft of humerus fractures: technique and outcome

INTRODUCTION

The humerus is subjected to substantial amount of torsional stress. Conventional plating may not address this sufficiently and may lead to fixation failure or non-union. A helical plate may offer the solution. We present the surgical technique and functional outcome of 5 cases of humeral shaft fractures treated with this technique in a minimally invasive way.

MATERIALS AND METHODS

The operations were performed between 2004 and 2010, by three surgeons. All the patients had closed humeral shaft fractures, either simple transverse or with mild comminution. Two small incisions were made. The proximal incision was placed along the deltopectoral groove over the shaft, and the distal incision was placed as in an antero-lateral approach. The radial nerve was identified and protected. A pre-selected plate was contoured and introduced in the submuscular plane. The plate was placed in a proximal-lateral and distal-anterior position. Screws were inserted through stab incisions. The patients were followed for an average of 6 months. Functional recovery of the shoulder and elbow was assessed using the Constant and Mayo elbow performance score systems.

RESULTS

All incisions healed by first intention without complications and all the fractures went on to unite. All patients achieved good to excellent shoulder and elbow function.

CONCLUSION

The helical plate technique is a safe and effective method of treating humeral shaft fractures and has good functional outcome.

Surgical treatment of adult extra-articular distal humeral diaphyseal fractures using an oblique metaphyseal locking compression plate via a posterior approach

OBJECTIVE

The purpose of this study was to evaluate the feasibility and clinical outcome of using an oblique AO (Association for the Study of Internal Fixation) metaphyseal locking compression plate (MLCP) in the treatment of adult extra-articular distal humeral diaphyseal fractures via a posterior approach.

SUBJECTS AND METHODS

A series of 19 cases of adult extra-articular distal humeral diaphyseal fractures were surgically treated using an MLCP and lag screws, if necessary, via a posterior approach. All patients were followed for a mean time of 16.6 months (range from 12 to 20 months). The patients were followed up to 1 year, and radiological assessment was performed to observe fracture reduction and healing. Functional outcome was measured including the range of motion of the shoulder and elbow, by the University of California at Los Angeles and the Mayo Elbow Performance Score.

RESULTS

The incidence of iatrogenic radial nerve palsy was 5%. There was no failure of internal fixation and no infection. After 1 year, the University of California at Los Angeles scoring system rated 12 (63.2%) patients as excellent results. The Mayo elbow performance scoring system rated 10 (84%) cases as excellent results. Completely normal alignment was presented in 16 cases.

CONCLUSION

Following surgical treatment of adult extra-articular distal humeral diaphyseal fractures, an oblique MLCP applied via a posterior approach achieved an adequate internal fixation and obtained an excellent functional outcome.

Plating of acute humeral diaphyseal fractures through an anterior approach in multiple trauma patients

OBJECTIVE

We evaluated the clinical and long-term functional outcomes of humeral diaphyseal fractures treated with acute anterior plating in a trauma population.

DESIGN

Single-center, retrospective cohort analysis with long-term prospective follow-up.

SETTING

Urban, Level I trauma center.

PATIENTS

Ninety-six patients with high-energy fractures of the humeral shaft were treated over a 10-year period.

INTERVENTION

All patients were treated by a standard surgical protocol of open reduction through an anterior approach with small or large fragment fixation in the supine position.

MAIN OUTCOME MEASUREMENTS

Mechanism of injury, time to union, complications, and range of motion during clinical follow-up were obtained. We also prospectively assessed long-term strength, range of motion, and perceptions of disability using the Disabilities of the Arm, Shoulder and Hand questionnaire.

RESULTS

Mean time to surgery was 5 days (standard deviation, 11 days); 97.5% of patients achieved union in an average of 16.9 weeks (range, 6-56 weeks). Complications included two postoperative infections, two nonunions, and three implant failures. Long-term follow-up (n = 34) averaged 4.75 years (range, 1.4-10.8 years). On average, no significant differences between the injured and uninjured extremities were seen in range of motion at the shoulder and elbow with the exception of shoulder flexion. A modest loss of upper extremity strength in the injured arm was appreciated. The mean Disabilities of the Arm, Shoulder and Hand score was 25.9 (range, 0-79).

CONCLUSIONS

A standard anterior surgical approach with small fragment fixation is a safe and effective treatment for humeral shaft fractures in multiple trauma patients. We show a high union rate and few complications, although a modest loss of function and some perceived disability exists in the long-term.

A simple and effective implant for displaced fractures of the greater tuberosity: the "Bamberg" plate

Displaced fractures of the greater tuberosity are common findings in trauma surgical patients. Nevertheless, osteosynthesis of these fractures impairs the risk of secondary dislocation or secondary impingement due to the implant (e.g., 4.5 mm cancellous screws with spiked washers). We present an easy and simple technique/implant to perform an osteosynthesis of multiple-fractured greater tuberosity fractures. We use a self-adjusted calcaneus titanium plate (Litos) which is cut into a 6 or more holed small plate. In ten patients we had excellent postoperative outcomes with no complications and no secondary loss of reduction. The surgical technique is easy and efficient.

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.

Sub-muscular plating of the humerus: an emerging technique

OBJECTIVE

The purpose of the present study was to evaluate percutaneous sub-muscular internal fixation using a locked screw methodology for treatment of diaphyseal humeral fractures.

METHODS

Inclusion criteria were multiple extremity fractures, open fractures, neurovascular injuries,additional ipsilateral upper extremity fractures, the inability to obtain a satisfactory closed reduction and isolated fractures with circumstances that prevented effective bracing. Exclusion criteria were immaturity, neoplasm, infection and intra-articular extensions in the same bone. Outcome measures included clinical and radiographic healing, complications, elbow and shoulder symptoms, range of motion (ROM) and Constant–Murley (CM) scores.

RESULTS

Thirty-one patients with 32 fractures were evaluated with a mean follow-up of 16 months (3–38 months). There was radiographic healing in 31 out of the 32 fractures; the non-union was revised to open plating at 6 months and healed uneventfully. Hardware complications included two construct disengagements; one patient was revised and healed, and the other achieved union with bracing.Neurovascular complications included one preoperative nerve palsy that recovered by 3 months, two partial to complete postoperative nerve palsies that recovered by 6 months, and one intact-to-complete nerve palsy due to a bone fragment that required decompression with full recovery by 3 weeks. All patients had functional ROM with a mean CM score of 88. There were no elbow complaints and minor shoulder dysfunction occurred in two patients with ipsilateral shoulder injuries. The rate of neurovascular complications was comparable to open plating techniques and all patients had full recovery.

CONCLUSION

We feel sub-muscular anterior plating of the humerus using locking screw technology is a viable and useful method for diaphyseal humeral fractures.

Outcome of nonoperative vs operative treatment of humeral shaft fractures: a retrospective study of 213 patients

Standard treatment for most humeral shaft fractures is nonoperative functional bracing; however, certain clinical scenarios necessitate operative intervention. There have been few studies in the literature comparing nonoperative and operative fixation of humeral shaft fractures. Two-hundred thirteen adult patients with a humeral shaft fracture who satisfied inclusion criteria were treated at 2 level 1 trauma centers with either a functional brace (nonoperative treatment group) or compression plating (operative treatment group). Main outcome measures were evaluated retrospectively and included time to union, nonunion, malunion, infection, incidence of radial nerve palsy, and elbow range of motion (ROM). The occurrence of nonunion (20.6% vs 8.7%; P=.0128) and malunion (12.7% vs 1.3%; P=.0011) was statistically significant and more common in the nonoperative group. There was no significant difference in infection rate between nonoperative and operative treatment (3.2% vs 4.7%; P=1.0000). Radial nerve palsy presented after fracture treatment in 9.5% of patients in the nonoperative group and in 2.7% of patients managed operatively (P=.0678). No difference in time to union or ultimate ROM was found between the 2 groups. Closed treatment of humerus fractures had a significantly higher rate of nonunion and malunion while operative intervention demonstrated no significant differences in time to union, infection, or iatrogenic radial nerve palsy. Nonoperative management has historically been the treatment of choice for many humeral shaft fractures, however, in certain clinical scenarios these fractures may be well served by compression plating.

Safety and efficacy of conversion from external fixation to plate fixation in humeral shaft fractures

OBJECTIVE

Immediate external fixation and planned conversion to internal fixation of humeral shaft fractures is an option in the treatment of associated severe soft-tissue injuries and severely injured patients. The purpose of this study was to evaluate the outcome and complications of patients who sustained humeral shaft fractures and were treated with initial unilateral external fixation followed by plate fixation.

DESIGN

Retrospective analysis of a prospective database.

SETTING

Academic level I trauma center.

PATIENT/PARTICIPANTS

We identified 17 patients treated between June 2003 and August 2007 with immediate unilateral external fixation followed by planned conversion to internal plate fixation. All patients were seen for follow-up until bony union occurred, with a minimum follow-up of 6 months.

MAIN OUTCOME MEASUREMENTS

Initial patient condition, local and systemic complications, and short-term outcomes were evaluated.

RESULTS

The main reason for immediate placement of an external fixator was multiple trauma in nine patients (damage control orthopedics group); six open fractures with massive soft-tissue injury; one temporarily decreased perfusion to the forearm and hand; and one associated compartment syndrome of the upper arm. The average timing of the conversion to internal fixation was 6.2 (range, 2-14) days from the time of external fixation. There were no iatrogenic nerve injuries after either the external fixation or the conversion to internal fixation. Fifteen of 17 fractures united with an average time to healing of 11.1 (range, 8-14) weeks. Two fractures failed to heal after conversion from external to internal fixation. Both were open fractures from the non-damage control orthopedics group that developed a deep infection. There were no systemic complications after conversion from external to internal fixation.

CONCLUSIONS

Immediate external fixation with planned conversion to plate fixation within 2 weeks proved to be a safe and effective approach for the management of humeral shaft fractures in selected patients with multiple injuries or severe soft-tissue injuries that preclude early plate fixation.

Early full range of shoulder and elbow motion is possible after minimally invasive plate osteosynthesis for humeral shaft fractures

OBJECTIVES

To measure the speed of full shoulder and elbow range of motion recovery following minimally invasive plate osteosynthesis (MIPO) for humeral shaft fractures.

SETTING

University Hospital.

PATIENTS

From March 2005 to July 2007, 14 consecutive patients with closed humeral shaft fractures underwent surgery by a single surgeon.

INTERVENTION

The MIPO technique involved proximal delto-bicipital incision and distal brachialis-splitting incision. A narrow locking 4.5/5.0-mm compression plate was applied percutaneously on the anterior surface of the humerus.

MAIN OUTCOME MEASUREMENTS

The intervals between operation date and the day when range of motion recovered to normal in the shoulder and elbow joint.

RESULTS

Median time to normal motion recovery was 19 days in the shoulder, and 60 days in the elbow.

CONCLUSIONS

MIPO is a promising option for humeral shaft fractures because of the early recovery of motion in adjacent joints. Elbow function requires longer recovery time than the shoulder, and this may be due to the distal approach.

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.

Plating osteosynthesis of mid-distal humeral shaft fractures: minimally invasive versus conventional open reduction technique

Results of two methods, conventional open reduction-internal plating and minimally invasive plating osteosynthesis (MIPO), in the treatment of mid-distal humeral shaft fractures were compared. Thirty-three patients were retrospectively analysed and divided into two groups. Group A (n = 17) patients were treated by MIPO and group B (n = 16) by conventional plating. The mean operation time in group A was 92.35 +/- 57.68 minutes and 103.12 +/- 31.08 minutes in group B (P = 0.513). Iatrogenic radial nerve palsy in group A was 0% (0/17) and 31.3% in group B (5/16 (P = 0.012). The mean fracture union time in group A was 15.29 +/- 4.01 weeks (range 8-24 weeks), and 21.25 +/- 13.67 weeks (range 10-58 weeks) in group B (P = 0.095). The mean UCLA end-result score in group A was 34.76 +/- 0.56 points (range 33-35), and 34.38 +/- 1.41 points (range 30-35) in group B (P = 0.299). The mean MEPI in group A was 99.41 +/- 2.43 points (range 90-100) and 99.69 +/- 1.25 points (range 95-100) in group B ( P = 0.687). When compared to the conventional plating techniques, MIPO offers advantages in terms of reduced incidence of iatrogenic radial nerve palsies and accelerated fracture union and a similar functional outcome with respect to shoulder and elbow function.

Minimally invasive plating osteosynthesis (MIPO) of middle and distal third humeral shaft fractures

OBJECTIVE

To evaluate the clinical, radiographic, and functional outcomes of middle and distal third humeral shaft fractures treated with the minimally invasive percutaneous osteosynthesis (MIPO).

DESIGN

Prospective, single-center, nonconsecutive clinical series study.

SETTING

: Skeletal trauma center of a university teaching hospital.

PATIENTS

Thirteen patients who were seen from May 2004 to October 2005 with an average age of 38.1 years (range, 25 to 60 years) form the basis of this study. Patients were obtained from a surgical database of 1 surgeon.

INTERVENTION

The middle and the distal third humeral shaft fractures were reduced by closed means and fixed with long narrow 4.5-mm dynamic compression plates introduced through 2 small incisions away from the fracture sites and placed on the anterior aspect of the humerus.

MAIN OUTCOME MEASUREMENTS

Time to fracture healing and functional assessments were assessed at an average follow-up of 12.5 months (range, 7 to 19 months) for the affected shoulders and elbows using the UCLA and Mayo elbow performance scoring systems, respectively.

RESULTS

All fractures united with a mean healing time of 16.2 weeks (range, 12 to 32 years). There were no nonunions, radial nerve palsies, or implant failures. The UCLA scoring system showed excellent results in 7 cases (53.8%) and good results in 6 cases (46.2%). Thirteen patients had excellent results of their elbow function when assessed with the Mayo elbow performance scoring system.

CONCLUSION

Closed reduction and internal fixation of middle or distal third humeral shaft fractures using MIPO is a safe and effective surgical treatment method and an alternative option to open techniques.

Percutaneous fixation of comminuted fractures of the humerus: initial experience at Al Razi hospital, Kuwait

OBJECTIVE

To present initial experience of 12 cases of percutaneous plating of the comminuted fractures of the humerus using minimal access surgery and standard low-contact dynamic compression plate.

PATIENTS AND METHODS

Twelve patients (11 males and 1 female) with an average age of 29.8 years (range 17-46 years) with comminuted diaphyseal fractures of the humerus were treated by minimal access surgery using standard AO/ASIF implants. Fracture was reduced indirectly either by manipulation or by a femoral distractor. Image intensifier was used to monitor the reduction and fixation. The plate was fixed on the anterior surface of the humerus using proximal and distal minimal incision on the anterior aspect of the upper arm.

RESULTS

All fractures were united, and all patients had a good range of motion in the adjacent joints. In 1 patient, there was a transient neurological deficit.

CONCLUSION

Percutaneous fixation of comminuted fractures of the humeral shaft is an alternative to standard open surgery, reducing the surgical impact and giving an excellent functional result.

Functional treatment of closed humeral shaft fractures

We treated 93 consecutive patients, average age 53 (16-90) years, with closed humeral shaft fractures applying a functional brace immediately after injury. Seventy-two (77%) fractures healed without problems. There were significantly more consolidation problems in fractures in the proximal third (46% consolidated) compared to those at the middle (81% consolidated) and distal third (86% consolidated) of the shaft. Logistic regression analysis revealed the only predictive factor in respect to successful brace treatment was fracture location. No significant difference was found in respect to healing between different AO-type fractures.
