New technique for humerus shaft fracture retrograde intramedullary nailing

Humeral shaft fracture intramedullary nailing is less invasive than plates and screws. Antegrade technique has postoperative shoulder pain, increased rehab time, and frequent reoperation for rod removal. Published retrograde technique is not collinear with the shaft, has insertion site fractures (5% to 15%), and radial nerve palsies (5%). Our retrograde technique is collinear with the humerus shaft, simpler, and decreases operative fracture risk. The supine patient's elbow is fully flexed. A guide pin is inserted through the triceps tendon to the olecranon fossa roof, aligned with the humerus shaft, and drilled thought the cortex followed by the 6.5 mm cannulated drill through a small triceps splitting incision. The guide pin is passed along the humerus shaft and across the fracture. A small incision is made to identify and protect the radial nerve during reduction, reaming, and rod insertion. Flexible reamers are used and the nail placed and locked at least distally to prevent distal migration. An institutional review broad approved retrospective review of Louisiana State University Health Sciences Center adult humeral shaft fractures with retrograde technique from 1999 to January of 2009 was carried out. Sixteen patients were treated without perioperative fracture or nerve palsy.

Closed humeral shaft fractures treated by elastic intramedullary retrograde nail

25 humeral shaft fractures operated on at our institute with the intramedullary elastic Marchetti-Vicenzi nail were reviewed. Three were pathologic fractures. Patients mean age was 48 ranging from 13 to 95 years. The patients were followed until consolidation and shoulder and elbow function were evaluated with respectively the Constant and the Mayo Clinic score. All the fractures eventually healed with good clinical results. There were no major complications during nail insertion. The M-V nail has been shown to be a practical and reliable device, characterised by both an easy technique and a stable fixation, with a low complication rate and low X-rays exposure times. The choice of an elastic unreamed intramedullary nail, with a retrograde insertion, that allows a solid for proximal fixation by means of a bundle of divergent pins, has proven to be useful and safe for shoulder function.     

Single retrograde intramedullary wire fixation of metacarpal shaft fractures

From 1993 to present day, 110 metacarpal fractures in 89 patients were stabilised using a method of inserting a percutaneous intramedullary wire. This allowed for early unimpeded movement in wrist and hand together with ease of wire removal in clinic. Reduction was maintained in all patients until fracture healing, and there were no malunions. One was re-done owing to inadequate reduction intra-operatively, which thereafter united. One re-fractured and was subsequently treated non-operatively. There were two superficial infections. One patient was lost to follow-up at 4 weeks; the rest regained a full range of pain-free movement. In a final assessment of 62 patients, the mean DASH score was 4.6. We recommend this technique for metacarpal fractures that are: transverse and off-ended; angulated transverse or short oblique; multiple transverse or short oblique. We do not recommend this technique for long oblique or rotationally malaligned fractures.     

膨胀自锁式髓内钉——一种新型骨折内固定材料

目前，交锁髓内钉内固定技术是治疗四肢长管状骨骨折的标准方法。但交锁髓内钉治疗需在x线透视下定位锁钉，常需扩髓，损伤髓内血供，由于应力集中于锁钉上，易导致远端锁钉断裂及骨折。因此，以色列一些学提出“膨胀自锁式髓内固定”的概念，根据这种全新的骨折内固定概念，设计出一种可以根据患髓腔空间改变主钉的直径、产生满意的抓握力、避免扩髓、无需远端锁钉及基本不使用x线辅助的新型髓内钉系统。[第一段]     

Nonunited humerus shaft fractures treated by external fixator augmented by intramedullary rod

Background:

Nonunion of humeral shaft fractures after previously failed surgical treatment presents a challenging therapeutic problem especially in the presence of osteoporosis, bone defect, and joint stiffness. It would be beneficial to combine the use of external fixation technique and intramedullary rod in the treatment of such cases. The present study evaluates the results of using external fixator augmented by intramedullary rod and autogenous iliac crest bone grafting (ICBG) for the treatment of humerus shaft nonunion following previously failed surgical treatment.

Materials and Methods:

Eighteen patients with atrophic nonunion of the humeral shaft following previous implant surgery with no active infection were included in the present study. The procedure included exploration of the nonunion, insertion of intramedullary rod (IM rod), autogenous ICBG and application of external fixator for compression. Ilizarov fixator was used in eight cases and monolateral fixator in ten cases. The monolateral fixator was preferred for females and obese patients to avoid abutment against the breast or chest wall following the use of Ilizarov fixator. The fixator was removed after clinical and radiological healing of the nonunion, but the IM rod was left indefinitely. The evaluation of results included both bone results (union rate, angular deformity and limb shortening) and functional outcome using the University of California, Los Angeles (UCLA) rating scale.

Results:

The mean follow-up was 35 months (range 24 to 52 months). Bone union was obtained in all cases. The functional outcome was satisfactory in 15 cases (83%) and unsatisfactory in 3 cases (17%) due to joint stiffness. The time to bone healing averaged 4.2 months (range 3 to 7 months). The external fixator time averaged 4.5 months (range 3.2 to 8 months). Superficial pin tract infection occurred in 39% (28/72) of the pins. No cases of nerve palsy, refracture, or deep infection were encountered.

Conclusion:

The proposed technique is effective in treating humeral nonunion especially in the presence of osteoporosis and short bone segments. The inclusion of intramedullary rod as internal splint improves stability of fixation and prevents refracture after fixator removal.

Treatment of pathological humerus shaft fractures with intramedullary nails with or without cement fixation

Introduction  

Bone metastasis is a severe complication for patients with cancer. Not only does it cause intractable pain and other clinical problems such as fracture after trivial injury, it also signifies that the malignant process is incurable. Since life expectancy of metastasised cancer patients has improved due to advanced oncological treatment but is still limited, appropriate surgical intervention has increased.
