Infected nonunion of the long bones.

The problems in infected nonunion include multiple sinuses, osteomyelitis, bone and soft tissue loss, osteopenia, adjacent joint stiffness, complex deformities, limb-length inequalities, and multidrug-resistant polybacterial infection. Bone gap and active infection are the crucial factors relating to treatment and prognosis. Gaps larger than 4 cm likely cannot be effectively bridged by corticocancellous bone grafting. If the limb has intact distal circulation and sensation, limb salvage and reconstruction generally is preferable to amputation. The fracture generally unites if adequate debridement of the nonunion site is done with fracture stabilization and bone grafting. We reviewed 42 consecutive patients with infected nonunion of the long bones. These patients have been categorized into two groups. Type A is infected nonunion of long bones with nondraining (quiescent) infection, with or without implant in situ; Type B is infected nonunion of long bones with draining (active) infection. Both are classified further into two subtypes: 1) nonunion with a bone gap smaller than 4 cm or 2) nonunion with a bone gap larger than 4 cm. Single-stage debridement and bone grafting with fracture stabilization are the methods of choice for Type A1 infected nonunions. Adequate debridement, fracture stabilization, and second-stage bone grafting gives desirable results in Type B1 infected nonunions. Distraction histiogenesis is the preferred procedure for Type A2 and B2. The autogenous nonvascularized fibular graft, posterolateral bone grafting for the tibia, and centralization of the ulna over distal radial remnant (single bone forearm) may be good treatment options in selected cases.

Treatment of diaphyseal fractures of the humerus using a functional brace.

OBJECTIVE: To determine humeral diaphyseal fractures at risk for nonunion with functional brace treatment. DESIGN: Retrospective case series. SETTING: A single surgeon's practice. PATIENTS: Forty-nine of 52 consecutive patients treated nonoperatively for an isolated diaphyseal fracture of the humerus during a 6-year period were followed until either union and full or near-full restoration of shoulder and elbow motion, or until 6 months had passed, or until a reconstructive surgery was performed (average follow-up 14 months; range 2 to 50 months). INTERVENTION: Functional fracture brace. MAIN OUTCOME MEASUREMENTS: Radiographic and clinical union. RESULTS: Union was achieved in 44 of 49 patients (90%) with no more than 15-degree loss of shoulder or elbow motion in any patient. Four of 14 proximal-third fractures (29%), one of 22 middle-third fractures (4%), and none of the 13 distal-third fractures failed to heal. CONCLUSIONS: Proximal-third long oblique fractures may be at greater than average risk for nonunion after functional fracture bracing. LEVEL OF EVIDENCE: Level IV (case series).

Complications of locked nailing in humeral shaft fractures.

BACKGROUND: The purpose of this study was to investigate the complications of humeral locked nailing. METHODS: Between 1994 and 2000, 161 humeral shaft fractures (98 acute fractures and 63 delayed unions or nonunions) in 159 patients treated with humeral locked nails were followed up for an average of 25.4 months. There were 89 men and 70 women, with an average age of 53.5 years. Acute fractures included 68 closed, 18 type I, 8 type II, 3 type IIIA, and 1 type IIIB open fractures. Thirty-six nonunions had previous operations. In general, acute fractures were treated with closed nailing and nonunions were treated with open nailing with bone grafting. Since 1998, interfragmentary wiring has been added in nonunions to compress the fracture. RESULTS: In total, 30 patients had 31 significant complications. Nine of them were persistent nonunions, six from acute fractures and three from nonunions. Fracture gap was associated with a significantly higher risk of nonunion. The risk of operative comminution was significantly higher in retrograde nailing, and operative comminution resulted in a significantly higher risk of nonunion. Seven of the nine nonunions underwent revisional nailing and achieved eventual union. Removal of the protruded screws was performed in two cases. Other complications included shoulder impairment, elbow impairment, angular malunion, and post-nailing radial nerve palsy. CONCLUSION: Many complications of humeral locked nailing can be prevented by improving the implant design or surgical techniques. The patients with persistent nonunion can be reliably treated by revisional nailing and bone grafting.

Lateral humeral condylar fractures in children.

Fifty-three patients with 56 fractures of the lateral humeral condyle were reviewed and the results were assessed to determine the amount of displacement that could be relied on to produce satisfactory results. Closed treatment resulted in satisfactory results if the initial displacement did not exceed 2 mm. This required close follow-up for detection of displacement. Percutaneous pinning of nondisplaced and minimally displaced fractures is an acceptable alternative in any situation in which close scrutiny cannot be ensured. Those fractures with greater than 2 mm of displacement should be reduced, pinned, and immobilized for 6-8 weeks. Evidence of delayed union after 8 weeks is an indication for internal fixation and possibly bone grafting. Established nonunions in good position are best treated by open reduction and bone grafting. In this series, varus deformity was the most common deviation from a normal carrying angle. The functional results were invariably good regardless of the radiographic or clinical findings.

Nonunion of slightly displaced fractures of the lateral humeral condyle in children: an update.

Inadequate treatment continues to be the leading cause of nonunion of slightly displaced fractures of pediatric lateral humeral condyles, despite references to prevention in the orthopaedic literature. In most cases, the elbow was established nonunion can be salvaged by early stabilization and bone grafting, provided that the fragment is in acceptable position and the growth plate of the condylar fragment is open. Procrastination may allow the physis of the condylar fragment to close prematurely, preemptying the golden opportunity to salvage the child's elbow. The author has collected 23 similar cases from correspondence with 17 orthopaedic surgeons.

Late surgical treatment of lateral condylar fractures in children.

We describe four cases of successful late surgical treatment of lateral condylar fractures of the humerus performed 8 weeks and 2, 5, and 14 years after injury and review the literature on the subject. We suggest that children with symptomatic nonunion and malunion of these fractures can benefit from late surgical treatment at the time of diagnosis. We describe the technique of functional reduction and the regions in which anatomic reduction is precluded by remodeling or gross displacement of the fragment.

Inferential therapy to promote union of mandibular fractures.

Non-union of mandibular fractures is uncommon, but when it does occur it requires protracted treatment including further surgery. Nine patients with factors known to predispose to non-union out of 150 consecutive mandibular fractures received interferential therapy (I.T.) during the fixation period; all fractures united satisfactorily. In a retrospective study of 150 consecutive mandibular fractures previously treated by the same surgeons without I.T., three fractures resulted in non-union requiring grafting. Thus the incidence of non-union was 0% when I.T. was used and 2% in the control group.

Treatment of humeral shaft fractures with the Seidel intramedullary nail.

BACKGROUND: The use of intremedullary nails for the management of humeral shaft fractures has been controversial. Recently, the Seidel nail has become available. The purpose of this study was to review our initial experience with the Seidel nail. METHODS: A retrospective clinical and radiographic review of 25 consecutive patients treated with Seidel intramedullary humeral nail was performed. The nail was used for non-union in 10 patients, delayed union in four, acute fracture in eight and pathological fracture in three. Eighteen of the 19 survivors were clinically reviewed at an average of 15 months (range 8-15). Pain, function, satisfaction, shoulder power, range of motion and clinical outcome were graded using the UCLA shoulder score. RESULTS: Pain was present at the shoulder in four patients and at the fracture site in nine. Average shoulder abduction was 99 degrees and nine patients could not abduct the shoulder past 90 degrees. Sixty-six percent of patients reviewed were graded as only fair or poor using the UCLA shoulder score. In three patients rotational control was not achieved with the distal locking device at the time of surgery. Complications included non-union in 10 patients and three intra-operative fractures. CONCLUSIONS: Non-union was more likely to occur if rotational control was not obtained, or if the patient had the nail inserted for a previous non-union. Use of the Seidel nail frequently leads to shoulder pain and dysfunction. The distal locking device is unreliable and predisposes to non-union. We do not recommend the continued use of the Seidel nail.

Huckstep intramedullary nailing for non-union of humeral shaft fractures.

BACKGROUND: Various techniques of internal fixation for non-union of humeral shaft fractures have been attempted, leading to union rates of between 50 and 90% with persisting non-union causing pain and disability. Some of these techniques have led to shoulder and elbow dysfunction. METHODS: Eight patients treated with Huckstep nail fixation for humeral shaft non-union were reviewed and the rate of union was determined. Elbow and shoulder function were assessed as well as the presence of pain or disability. RESULTS: Union was achieved in seven of the eight patients (87.5%). Four patients had occasional mild pain after union. All patients achieved good arm function. Average shoulder abduction was 157 degrees and flexion 151 degrees excluding one patient with antecedent advanced osteoarthrosis of the gleno-humeral joint. No patient experienced any permanent neurological deficit. CONCLUSIONS: Huckstep nail fixation achieved union rates comparable to or higher than the other techniques of internal fixation for non-union of humeral shaft fractures. Unlike the various methods of closed nailing, Huckstep nail fixation is not associated with shoulder and elbow dysfunction. It should be considered as a therapeutic option in humeral shaft fracture and non-union, especially where the fracture site needs to be opened.

The use of locked nails in the treatment of humeral shaft: delayed union and nonunion.

OBJECTIVES: To assess the results and clinical outcome of delayed union and nonunion humeral shaft treatment using locked medullary nails. SUBJECTS AND METHODS: The Russel and Taylor humeral locking nail was used to treat 21 patients with humeral shaft fractures at Al Razi hospital, Kuwait, from 1997 to 2001. Of these, 8 had delayed union and 13 nonunion. Also, 13 had previous operative treatment, while 8 had nonoperative treatment. Antegrade nailing was done in all cases, and all nails were fixed statically. Autogenous iliac bone grafts were used in 17 cases. RESULTS: Of the 21 cases of fractures, 19 were united. Only 2 cases had persistent nonunion. Eighteen cases had satisfactory shoulder function, and 3 lost shoulder abduction between 40 and 65 degrees. CONCLUSION: Our data showed that humeral locked nails can achieve satisfactory clinical results in treating humeral shaft delayed unions and nonunions.

Pediatric jaw fractures: indications for open reduction.

Jaw fractures in children are generally managed without major surgical intervention. Closed reduction usually is sufficient to restore normal anatomy and function. The one inviolate principle is early treatment. During the past three years, four pediatric jaw fractures that required open reduction were treated. This mode of treatment was necessitated by the limitations imposed by pediatric dental anatomy and by the type of fractures encountered. In at least 24 months of follow-up, no dental problems have been seen.

Nonunion of olecranon stress fractures in adolescent baseball pitchers: a case series of 5 athletes.

BACKGROUND: Adolescent athletes participating in overhead throwing sports suffer a variety of overuse elbow injuries, many of which have been well described in the literature. Nonunion stress fractures of the olecranon across the epiphyseal plate, however, have received little attention. PURPOSE: To describe this unusual clinical entity in the differential diagnosis of the adolescent athlete with elbow pain and to demonstrate that operative treatment is an effective means of quickly and safely returning the patient to sporting activities. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Five adolescent baseball pitchers (mean age, 15 years) who suffered chronic elbow pain and who were diagnosed with olecranon epiphyseal stress fracture nonunions were treated with open reduction and internal fixation using a 7.0 cancellous screw and washer with or without 18-gauge tension banding. RESULTS: Return to preoperative range of motion was achieved at a mean of 8.6 weeks (range, 3.4-16.6 weeks). Patients were clinically asymptomatic at a mean of 11 weeks (range, 7.7-13.6 weeks) after surgery. Radiographic evidence of stress fracture union was achieved at a mean of 15.4 weeks (range, 6.1-33 weeks), including 1 patient with a delayed union according to radiographs, which healed at 33 weeks. Patients were started on a light strengthening program at 5 to 7 weeks and a throwing progression program at 15.6 weeks (range, 6.4-28.1 weeks). All 5 patients were able to return to their previous level of activities, with a mean return time of 29.4 weeks (range, 18.9-40.4 weeks). CONCLUSION: Surgical management of olecranon apophysis stress fractures provided excellent results with minimal complications in this series of 5 consecutive cases.

Treatment of pathological humeral shaft fractures with unreamed humeral nail.

PURPOSE: The purpose of this study is to analyze the results of intramedullary fixation of pathological humeral shaft fractures using an unreamed humeral nail (UHN). PATIENTS & METHODS: Twenty-one consecutive patients with 24 humeri fractured secondary to metastatic disease were retrospectively reviewed. The primary tumors included carcinomas of breast (11), kidney (2), multiple myeloma (2), colon (2), prostate (1), thyroid (1), lymphoma (1) and unknown origin (1). All fractures were stabilized with antegrade unreamed humeral nailing. Cemented technique was performed in 5 procedures. The mean age was 64 (range, 40-86), male to female ratio 6:15. RESULTS: Blood loss was unremarkable in 19 patients (22 procedures). Two patients who underwent fixation of additional pathological fractures during the same operation were given a total of 3 units of PC perioperatively. Mean postoperative hospitalization period due to one UHN procedure alone was 3 days (range, 2-7 days). Two patients died of their disease within 3 weeks of surgery. The remaining 19 patients returned to nearly normal function within 6 weeks after nailing. One patient developed postoperative local wound cellulitis. Relief of pain was rated as good in all but one patient. Adjuvant therapy was given in 20 procedures. Bony union was achieved in 88% (15/17) of all the cases where the patient had survived a minimum of 3 months. CONCLUSION: Unreamed humeral nailing of the pathological humeral shaft fractures provides immediate stability and pain relief, minimum morbidity and early return of function to the extremity.

Endoprosthetic replacement of the humerus and elbow joint.

Between 1969 and 1985 26 patients with destructive lesions of the distal humerus were treated by endoprosthetic replacement; each implant was custom-made and incorporated part of the distal humerus or the entire bone as well as a hinged total elbow replacement. Recurrence occurred in three of the patients with tumours, and three prostheses were removed because of deep infection in patients with previously compound injuries of the elbow. Another three loosened without infection, but none needed revision or removal and no amputations resulted. Other complications included nerve palsies, but the only deaths were from metastases. A useful range of elbow movement, with a stable arm and good hand function, was achieved in every patient.

Nonunion of the humerus after failure of surgical treatment. Management using the Ilizarov circular fixator.

We used the Ilizarov circular external fixator to treat 16 patients with persistent nonunion of the diaphysis of the humerus despite surgical treatment. All patients had pain and severe functional impairment of the affected arm. In ten, nonunion followed intramedullary nailing. We successfully treated these by a closed technique. The nail was left in place and the fracture compressed over it. The fractures of the other six patients had previously been fixed by various methods. We explored these nonunions, removed the fixation devices and excised fibrous tissue and dead bone before stabilising with the Ilizarov fixator. In five patients union was achieved. Bone grafting was not required. In the single patient in whom treatment failed, there had been a severely comminuted open fracture. All except one patient had reduction of pain, and all reported an improvement in function.

Use of the coventry infant hip screw in the treatment of nonunion of fractures of the distal humerus.

Between 1993 and 2000 we treated 14 patients with nonunion of fractures of the distal humerus; 11 had already had previous fixation which had failed. The mean time to surgery was 21 months after injury. All the fractures were very low which made it difficult to obtain a firm hold of the small distal fragment. The problem of fixation was addressed by inserting a Coventry infant hip screw into the humeral condyles. The screw has a thread of wide diameter which gives excellent purchase on the small distal fragment. The condyles can then be compressed on to the humeral shaft using a 4.5 mm narrow tibial dynamic plate. Of these 14 difficult cases of nonunion, 12 progressed to union.
