Treatment of Complete Brachial Plexus Injuries Using Double Free Muscle Transfer

The purpose of this study was to examine the surgical outcomes of double free muscle transfer (DFMT) performed in patients with complete brachial plexus injury (BPI). We retrospectively analyzed the outcomes of DFMT for 12 patients with complete BPI who were followed up for more than 2 years after the final muscle transplantation. Their mean age was 29 years (range, 18-41). Three patients underwent contralateral C7 nerve root transfer before the DFMT. The range of motion (ROM) of the shoulder, elbow, and fingers was measured. Patient-reported outcome measures, including Disability of the Shoulder, Arm, and Hand (DASH) scores and visual analog scale (VAS) scores for pain, were also examined. The mean shoulder ROM against gravity was 22° ± 8° in abduction and 33° ± 5° in flexion. Seven patients underwent phrenic nerve (PhN) transfer to the suprascapular nerves, and five exhibited asymptomatic lung impairment on spirography more than 2 years after PhN transfer. The mean elbow ROM against gravity was 111° ± 9° in flexion and -32° ± 7° in extension. All patients obtained elbow flexion >90° against a 0.5-kg weight. All patients obtained touch sensation and two recognized warm and cold sensations in the affected palm. The mean total active motion of the affected fingers was 44° ± 11°. All patients exhibited hook function of the hands. The mean preoperative and postoperative DASH scores were 70.3 ± 13.4 and 51.8 ± 15.9, respectively. The mean pain VAS score was 28 ± 31 at the final follow-up. Double free muscle transfer provided patients with complete brachial plexus palsy with good elbow flexion and hand hook functions.

Pedicled Functional Latissimus Flaps for Reconstruction of the Upper Extremity following Resection of Soft-Tissue Sarcomas

(1) Background: Resection of soft-tissue sarcomas (STS) of the upper extremity can result in substantial functional impairment with limited options for functional reconstruction. Free functional latissimus flaps have been utilized to restore function of the thigh; however, there is limited data on the use of latissimus flaps for functional reconstruction in the upper extremity. As such, we sought to evaluate our institutional experience with these flaps. (2) Methods: We reviewed ten (seven male; three female; and a mean age of 63 years) patients undergoing soft-tissue sarcoma resection involving the triceps (n = 4), biceps (n = 4), and deltoid (n = 2) reconstructed with a pedicled functional latissimus flap. All surviving patients had at least 1 year of follow-up, with a mean follow-up of 5 years. (3) Results: The mean elbow range of motion and shoulder elevation were 105° and 150°. The mean Musculoskeletal Tumor Society score was 88%, and the muscle strength was four. Four patients had a recipient site wound complication. There were no flap losses. One patient sustained a radiation-associated humerus fracture 5 years postoperatively, treated nonoperatively. (4) Conclusions: Although early complications are high, pedicled functional latissimus flaps allow for wound coverage, potential space obliteration, and restoration of function in the upper extremity following resection of large soft tissue sarcomas.

Retrospective review of pyrocarbon radial head replacement

Radial head arthroplasty is the preferred surgical management for complex, unreconstructable radial head fractures. There has been increasing use of pyrocarbon prostheses, with potential tribology and modulus advantages over metallic counterparts. This study aims to assess clinical and radiological outcomes for radial head replacement after trauma using a modular, uncemented pyrocarbon prosthesis. Between September 2009 and March 2020, a consecutive series of 22 trauma cases were available for review. Patients underwent radial head arthroplasty using a pyrocarbon prosthesis (Ascension Modular Radial Head System, Austin, TX). Recorded outcomes included clinical assessment, radiological evaluation, and patient-reported outcome measures specific to elbow function. Twenty-two patients (7 male, 15 female) with an average age of 51 years (range 21-64) were analyzed with a minimum 12 months of follow-up. All patients had complex radial head fractures, categorized as a Mason 3 or 4 injury. At follow-up, mean elbow range of motion included flexion 130° (range 100°-150°), extension 19° (0-50°), pronation 73° (30°-90°), and supination 70° (10°-90°). The mean Mayo Elbow Performance Index score was 83 (55-100), and Disabilities of the Arm, Shoulder and Hand score was 22 (2.5-60). Radiological evaluation showed 14 patients with asymptomatic proximal neck resorption and two patients with radiological stem loosening. In total, 3 of 22 implants were revised-2 were excised, and 1 revised to a long stem for traumatic implant fracture. Pyrocarbon radial head arthroplasty provided reliable functional results for patients after unreconstructable radial head fracture. The unique potential for fracture of the prosthesis should be considered in long-term follow-up, with appropriate activity advice to patients.

Surgical management of humeral shaft nonunions. Success of a consistent protocol over 17 years

IntroductionSurgical treatment of humeral shaft nonunions is characterized by variability of fixation methods, graft choices, and rates of union and iatrogenic radial nerve palsy. The aim of the current study is to evaluate the union rate of humeral shaft aseptic nonunions and the rate of postoperative complications following a consistent management protocol. Patients and methodsThis is a retrospective review of 41 consecutive adult patients (23 female and 18 male with a mean age of 42 years) with aseptic nonunions of the humeral shaft treated by the senior author in our institution over a 17-year period. Nonunions were located in the middle third of the diaphysis in 33 patients, in the distal third in 6, and in the proximal third in 2 patients. Comorbidities were present in 49% of patients and the most common were smoking in 27% and diabetes mellitus in 17% of patients. Patients were treated at an average of 24 months after their injury. Surgical protocol consisted of careful dissection of the radial nerve, debridement of the nonunion site, stable plate fixation and augmentation of local biology. ResultsThirty-eight patients had mean clinical and radiographic follow-up of 9.4 months. All 38 nonunions healed at a mean time of 3.5 months. There were no persistent nonunions and no failures of fixation. None of the 40 patients with an intact radial nerve preoperatively developed any signs of radial nerve compromise after surgery. Complications consisted of one superficial infection (2%) that resolved with oral antibiotics and one deep infection (2%) that required implant removal and debridement. The mean pain score on the visual analog scale was 0.7. Mean elbow range of motion was 125 degrees with a mean extension deficit of 5 degrees and mean flexion of 130 degrees. ConclusionsOur surgical protocol achieved consistent healing of nonunions of the humeral shaft with a low complication rate and no iatrogenic radial nerve palsy, even in long-standing nonunions in patients with comorbidities.

Does Radial Head Resection Impair Hand and Wrist Function? A Long-Term Follow-Up.

To evaluate the long-term outcome in patients after radial head resection surgery for isolated Mason type III radial head fractures. An observational retrospective case series. A Hand and Upper-Extremity Surgery Unit in a tertiary care center. Data were collected from files of patients who were operated between the years 1980 and 2020. Of 352 patients who underwent surgery for radial head fractures, 25 patients were eligible and were enrolled in the study. All participants underwent radial head resection surgery and a follow-up clinical and radiographic evaluation by 2 senior orthopaedic surgeons. Objective evaluation included active range of motion of the elbow and wrist joints, ulnohumeral angle, key pinch and grip measurements, and radiographic imaging of elbow and wrist joints. Subjective evaluation included visual analog scale measurements, disability of arm shoulder and hand questionnaire, Mayo wrist score, Michigan hand outcome, and Oxford elbow score. The mean follow-up was 18 years. Mean elbow range of motion and mean grip strength were lower in the operated hand, as compared to the contralateral hand. Mean proximal radial migration was 1.6 mm. Mean results of visual analog scale, disability of arm shoulder and hand, Mayo wrist score, Michigan hand outcome, and Oxford elbow score indicated good functional outcome and high patient satisfaction. In our study population, long-term functional outcomes after radial head resection were encouraging. Thus, this procedure may be considered as a surgical alternative when radial head reconstruction or replacement fails. Therapeutic Level IV.

Outcomes of nonoperative management of displaced olecranon fractures in medically unwell patients.

BackgroundSurgical treatment of displaced olecranon fractures in the elderly has a high rate of complications, including wound breakdown and fixation failure. The purpose of this study was to assess the clinical, radiographic, and functional outcomes of nonsurgical management of displaced olecranon fractures in low-demand elderly and medically unwell patients.MethodsA retrospective review of 28 patients with displaced closed olecranon fractures was performed with an average follow-up of 11 months. The mean age at the time of injury was 79 ± 10 years. The average Charlson Comorbidity Index was 6.4 ± 2.6. Treatment modalities were at the discretion of the treating surgeon. A sling alone was used in 3 cases, an extension circumferential cast in 9, or a plaster or thermoplastic splint in 16. The mean period of immobilization was 5 ± 1 weeks. Outcomes included range of motion, ability to perform active overhead extension, as well as radiographic and functional outcomes.ResultsAt final follow-up, the mean elbow range of motion for the cohort was from 28° ± 21° extension to 127° ± 15° flexion. Active overhead elbow extension against gravity was noted or documented in 24 (86%) patients. Two patients (7%) were unable to perform active extension. No pain was noted in 18 elbows, severe pain was present in 1 elbow, and the remainder reported mild occasional pain. All olecranon fractures in this cohort were displaced on the initial lateral radiograph. The mean displacement was 11 ± 7 mm. Nonunion at final radiographic outcome was observed in 23 (82%) elbows. Two (7%) patients developed skin complications related to posteriorly placed splints; one of which was severe.DiscussionThis study adds to the growing literature that supports nonoperative management of displaced olecranon fractures in elderly and medically unwell patients with low upper extremity demand. Patients can be counseled that they have a good chance of obtaining overhead extension, with minimal pain. Posteriorly based splints should not be used to minimize skin complications.

Trans-Olecranon Fracture-Dislocations of the Elbow: A Systematic Review

The purpose of this study is to provide a systematic review of the definition, ideal surgical method, complications, and prognosis of trans-olecranon fracture dislocations. An electronic search was performed in the PubMed, EMBASE, Scopus, and MEDLINE databases. The eligibility criteria included retrospective clinical study and review article in subjects older than 18 years with trans-olecranon fracture dislocations. Trans-olecranon fracture dislocations are defined as fractures in which the stability of the ulnohumeral joint is lost due to the intra-articular fracture of the olecranon without disruption of the proximal radioulnar joint. The seven papers were included that met the eligibility criteria for the quantitative synthesis. Findings indicate that a pre-contoured plate was used in 88.3% of cases (68 of 77 reports), with no reports of complications, suggesting that the pre-contoured 3.5 mm plate is the first choice of treatment. Postoperative mean elbow range of motion for the flexion–extension arc was 121.1° and 146.5° for the pronation-supination arc. Methods for postoperative clinical scores included the Broberg/Morrey rating with a result of excellent or good in 82.9% of cases, the ASES score with a mean of 88.7, and the DASH score with a mean of 11.75. Complications included heterotopic ossification in 21.9% (23/105) of cases, arthrosis in 25.7% (27/105) of cases, nerve damage in 18.1% (19/105) of cases, and osteoarthritis in 14.3% (15/105). With better understanding of the mechanism of injury and proper diagnosis and treatment, findings of the current review suggest a positive outcome. PROSPERO registration No.: CRD42019126568.

Triple management of cubitus valgus deformity complicating neglected nonunion of fractures of lateral humeral condyle in children: a case series.

Long standing nonunion of the lateral humeral condyle (LHC) usually results in elbow pain and instability with progressive cubitus valgus and tardy ulnar neuritis. Surgical treatment of long standing nonunion is still a controversial issue due to the reported complications, such as stiffness, loss of elbow motion, and avascular necrosis of the LHC fragment. In this study, we reported the outcomes of treatment of cubitus valgus deformity in long standing nonunion of the LHC in children treated with combined triple management (fixation of the nonunion site, dome corrective osteotomy, and anterior transposition of ulnar nerve) through a modified para-triceptal approach. We evaluated tenpatients with cubitus valgus deformity more than 20 degrees after neglected nonunion of the lateral humeral condyle more than 24months. Only childern with post-operative follow up more than 24months were included in this study. All patients were evaluated clinically, radio logically, and by pre- and post-operative functional evaluation using Mayo elbow performance score. For evaluation of ulnar nerve affection, the Akahori's system was used. There were six females and four males with the average age of 7.7years at operation. The left elbow was affected in six patients and the right elbow was affected in four patients. The average time between fracture of the LHC and operation was 40.3months with average post-operative follow up of 44.3months. The average carrying angle of the healthy side was 5.5 degrees and pre-operative carrying angle of the affected side was 33.5 degrees. The average post-operative carrying angle of the affected side was 6.1 degrees. The improvement of the carrying angle at the last follow up was found statistically significant (p < 0.05). All six patients that had pre-operative various degrees of ulnar nerve affection had completely improved at last follow up. The osteotomy site united in an average time of 43days, whereas the LHC nonunion site united in an average time of 77.2days. The osteotomy site united in significantly less time than the LHC non-union site (p < 0.05). The correlation between time since injury and time of union of LHC non-union site was significant (p < 0.05). Post-operative elbow range of motion was not changed in five patients, slightly decreased in four patients, and increased in one patient. Three patients had an average 6.7 degrees (range; 5-10) loss of the last degrees of flexion. One patient developed extension lag of 10 degrees. The mean elbow range of motion (ROM) pre-operatively was 139 ± 4.6 degrees while the mean post-operative ROM was 138 ± 5.3 degrees. The difference was found to be statistically insignificant (p > 0.05). The mean pre-operative Mayo elbow performance score was poor 55 ± 9.7, four patients had fair score, and six had poor score. The mean post-operative Mayo elbow performance score was excellent 92.5 ± 10, six patients had excellent score, and four had good score. The improvement of the Mayo score at the last follow up was found to be statistically significant (p < 0.05). No intra-operative complications were recorded during any of the procedures and no patient developed a wound or pin track infection post-operatively. At the last follow up, none of the patients had developed avascular necrosis of the LHC. Preservation of the blood supply of the nonunited fragment is the key to successful management. This combined technique successfully addresses different aspects of the problem simultaneously and provides a durable solution without deterioration of the results over time. The para-triceptal approach provided excellent exposure of both sides of the elbow with minimal disruption of the triceps muscle.

Modified anterolateral approach for internal fixation of Holstein–Lewis humeral shaft fractures

The authors modified the anterolateral approach for Holstein-Lewis humeral shaft fractures using a plating technique to achieve sufficient distal fixation by minimal splitting of the brachioradialis muscle to fix the most distal screws. The purpose of this retrospective study was to evaluate the efficacy of our modified anterolateral approach for Holstein-Lewis humeral fractures and document clinical and functional results. Between 2008 and 2014, 18 patients (mean age 35.4 years) with a Holstein-Lewis humeral shaft fracture who underwent open reduction and internal fixation with a plate and screws using the modified anterolateral approach and followed for a minimum of 12 months were included. Radiologic fracture configurations, number of distal cortical fixations, union rate, and time to union were analyzed. Clinical outcomes were evaluated using the Mayo elbow performance index system, range of elbow motion, and postoperative complications. Mean fracture length was 60.2±10.2mm (range 49.2-77.2) and mean distal cortical length was 41.4±7.04mm (range 22.8-59.6). Distal fragments were fixed at a minimum of six cortical points (range 6-8) in all cases using the modified anterolateral approach. Average time to union was 10.5 weeks (range 8-12 weeks). All cases of radial nerve palsy completely recovered within 3 months. Mean elbow range of motion at final follow-up was 3.2 degrees of flexion contracture (range 0-10) and 135.4 degrees of further flexion (range 120-140), and the average Mayo elbow performance score was 96.3 points (range 90-100). There were no non-union or metal failures. The results obtained indicate that the modified anterolateral approach is a safe and easy accessible method that provides sufficient distal osseous fixation for Holstein-Lewis humeral shaft fractures without serious complications. The modified anterolateral approach for plate osteosynthesis appears to be one of the most available options for the treatment of Holstein-Lewis humeral fractures. Level IV, retrospective case series.

EFFECTIVENESS OF Ilizarov TECHNOLOGY FOR INFECTED FOREARM NONUNION

To explore the effectiveness and method of Ilizarov technology for the treatment of infected forearm nonunion. Between January 2004 and March 2014, 19 patients with infected forearm nonunion were treated, including 12 males and 7 females with a mean age of 37.4 years (range, 18-62 years). The injury causes included traffic accident in 11 patients, falling from height in 4 patients, and machine twist injury in 4 patients. The patients had received surgical treatment for 1-5 times (mean, 2.7 times). Bone defects located at the radius in 10 cases, at the ulna in 7 cases, and at the radius and ulna in 2 cases. The mean time of chronic infection was 8.3 months (range, 4-16 months). The mean length of the bone defects after debridement was 3.54 cm (range, 2.2-7.5 cm). Under the guidance of C-arm fluoroscope, the Orthofix unilateral external fixator was used to fix. Distraction was performed at 7-10 days after operation, and X-ray film was taken regularly to detect the osteogenesis. The mean external fixation time was 6.5 months (range, 3-12 months), and the mean external fixation index was 1.72 months/cm (range, 1.14-2.15 months/cm). All patients were followed up for 35.4 months on average (range, 24-55 months). The bone union time was 3-11 months (mean, 6 months); and no recurrence of infection was observed. At last follow-up, the mean wrist range of motion (ROM) were 52.78° (range, 42-55°) in flexion and 46.53° (range, 40-60°) in extension; the mean elbow ROM were 139.23° (range, 130-150°) in flexion and 3.57° (range, 0-20°) in extension; and the mean forearm ROM were 76.68° (range, 68-90°) in pronation and 81.75° (range, 72-90°) in supination. Ilizarov technology for infected forearm nonunion can acquire satisfactory clinical results. Radical debridement is the key to control bone infection.

Capitellum Fracture Fragment Excision: a Case Series.

Fractures of the capitellum are rare injuries, and few studies have reported the results of fragment excision. The purpose of this study was to determine range of motion and short-term clinical outcomes for patients treated with capitellum excision. A retrospective review was performed to identify all patients with an isolated capitellum fracture who underwent excision as definitive treatment at our institutions. Mechanism of injury, associated elbow injuries, type of capitellum fracture, complications, and postoperative outcomes including final elbow range of motion (ROM), elbow instability, and Disabilities of the Arm, Shoulder and Hand (DASH) score were recorded. Four patients met the inclusion and exclusion criteria of this study. All patients were female with an average age of 69years (range 42-85). Based on the Bryan and Morrey classification system, three (75%) fractures were classified as type I and one (25%) fracture as type III. The average clinical follow-up was 11months. Final examination demonstrated a mean elbow range of motion from 14° (range 0-30) of extension to 143° (range 130-160) of flexion. All patients had full forearm rotation, and there was no clinical evidence of elbow instability. The average DASH score was 18.3 (12.5-24.2) at final follow-up. Excision of the capitellum, much like excision of the radial head, results in acceptable short-term outcome scores and elbow range of motion in patients with fractures that are not amenable to open reduction and internal fixation.

Old Unreduced Elbow Fracture and Fracture Dislocation: Treatment With Open Reduction and Hinge External Fixation

Background: Old unreduced elbow dislocation and fracture-dislocation, although rare, are one of the challenges in orthopedic surgery. The application of the hinged elbow external fixator can confer early range of motion after open reduction and reconstruction in spite of severe soft tissue and bony injury. Objectives: This study presents our results of open reduction and reconstruction in old simple elbow dislocation and old elbow fracturedislocation. Patients and Methods: In 12 patients with old elbow dislocation, open reduction and bone and soft tissue reconstruction was done and early postoperative range of motion was begun with the aid of hinged elbow external fixators. Results: The mean elbow range of motion at the final follow-up was 98 degrees (SD = 10). According to the Mayo Elbow Performance Index score, 6 patients achieved excellent results and 2 other had good results with a mean value of 92 (SD = 8). Conclusions: We recommend hinged elbow external fixation in old elbow dislocation for early range of motion and maintenance of concentric reduction with acceptable results.

Simple Medial Elbow Dislocations: A Rare Injury at Risk for Early Instability

To report the presentation, treatment, and outcomes of a series of simple medial elbow dislocations and to identify features distinguishing this injury from the more common dislocation patterns. From 2000 to 2011, 4 cases of simple medial elbow dislocations were treated at a single referral center. Retrospective review was conducted to evaluate presentation, treatment, and outcomes. The mean patient age was 56 years (range, 49-61 y). All dislocations were in the nondominant arm of women after a fall from standing height. Two elbows had immediate closed reduction, and 2 elbows could not be reduced acutely. All elbows presented within 2.5 weeks of injury with recurrent instability or dislocation. Two patients also had acute symptoms of ulnar neuropathy. All patients had surgical repair of the lateral collateral ligament complex and extensor tendon origin. Three patients had ulnar nerve decompressions. All elbows were stable to valgus, varus, and rotatory stress testing, with no subjective instability at a minimum follow-up of 8 months (range, 8-144 mo). Three patients reported no pain. Symptoms of ulnar neuropathy resolved in all patients. Mean elbow range of motion was from 13° to 135° of extension/flexion, with full pronation and supination. Simple medial elbow dislocations may be at risk for early instability and may represent a more noteworthy soft tissue injury than typical dislocation patterns. Surgical treatment of early instability in these injuries led to acceptable patient outcomes.

Coronal plane fractures of the distal humerus involving the capitellum and trochlea treated with open reduction internal fixation

Coronal plane fractures of the distal humerus involving the capitellum and trochlea are rare. Treatments have evolved from closed reduction to open reduction and internal fixation (ORIF) to achieve a stable joint that allows early mobilization. We determined the functional outcomes of treating coronal plane fractures of the distal humerus with ORIF. We reviewed the records of all patients with coronal plane fractures of the distal humerus treated by ORIF. Fractures were classified according to Bryan and Morrey. Cannulated screws were used for fixation. All patients were evaluated using the Mayo Elbow Score Performance Index (MEPI) and disabilities of the arm, shoulder, and hand (DASH) scores at least 1 year later. Of the 18 patients evaluated (12 women), the mean (SD) age was 45.3(16.5) years (range 16-70). There were seven Type-I, five Type-III, and six Type-IV fractures. Mean follow-up was 43.6 (38.1) months (range 12-120). The mean elbow range of motion in sagittal plane at last follow-up ranged from 8.9° to 132.8°. The mean MEPI score was 86.7 (15.2) points (range 60-100), corresponding to 12 excellent, 2 good, and 4 fair outcomes. The mean DASH score was 15.3 (13.5) points (range 17-35.8). Heterotrophic ossification developed in one patient with delayed fixation; 14 patients with excellent or good results returned to their previous activity levels. Functional scores did not differ by age, sex, or fracture types (P > 0.05 for all comparisons). ORIF with cannulated screws, which maintain a stable anatomic articular position, provides satisfactory results in coronal plane fractures of the distal humerus. Level IV case series.

Surgical treatment and functional outcome of open supraintercondylar fractures of the humerus

Abstract This is a retrospective study of the functional outcome of Orthopedics Trauma Association Type C open distal humerus fracture treated by posterior triceps splitting approach. There were 10 patients with mean age of 50 years (18–76 years). Two C1, five C2, and three C3 open fracture were included in this study. Nine patients were treated with open reduction and fixation with posterior double plate and one was treated with a single plate and multiple Kirchner wire fixations by posterior tricep splitting approach. The mean casting period was 5–8 weeks for C3 fracture and the period of long arm splint was 4 weeks for C1 and C2 fractures. The mean follow-up period was 34 months. Eight patients were operated within 6 hour after injury and one was delayed for 2 days and another for 3 days because of severe swelling and poor general condition. Functional outcome was evaluated by Mayo elbow performance score. The mean score was 81.5 point (standard deviation 9.4). Seven patients had good to excellent result and three patients had fair result. Mean elbow range of motion was 81°. Complications included two superficial wound infection and two nonunion. Neither implant failure nor ulnar nerve injury nor heterotopic ossification was noted during this follow up period. Two patients had delayed operation 2–3 days after stabilizing other associated injury. Immediate open reduction and internal fixation of open intra-articular fracture of the distal humerus is a safe and effective technique with a low rate of infection and complications.

Single-stage treatment of complete dislocation of radial head and forearm deformity using distraction osteogenesis in paediatric patients having multiple cartilaginous exostosis

We are reporting the results of single-stage treatment for patients with forearm deformity and radial head luxation due to hereditary multiple exostosis using distraction osteogenesis. Six patients with a mean age of 12 years were treated. Morphological evaluation was made according to Masada (3 of the cases were 2a and 3; 2b). Angular deformities of forearm and wrist were evaluated as described by Fogel (distal radial joint angle was 27°, ulnar variance was 12.8 mm and carpal slip was 71.3%). Mean forearm pronation was 48.4° whilst mean supination was 19.2°. Mean elbow range of motion was 26.6°-103.4° and the mean DASH score was 75. Common surgical procedures were deformity correction, ulnar lengthening and gradual radial head reduction using external fixators. Mean follow-up period was 4.2 years and mean external fixation time was 6 months. Mean amount of ulnar lengthening was 2.9 cm and the distraction index was 14.9 cm/day. Mean radial articular angle was 14.3°, ulnar variance 2.3 mm, carpal slip 55%, forearm pronation 65.9° and supination was 55°. Mean elbow range of motion was 15.8°-119.2°. In the last follow-up, the mean value of DASH score was 8.1. Major and minor complications were seen during the follow ups. Single-stage deformity correction, ulnar lengthening and radial head reduction technique that we have used provide satisfactory functional and cosmetic results. Early surgical correction may lead to even better results.

Surgical treatment of acute coronoid process fractures

This study was designed to assess the results of surgical treatment for type 2-3 coronoid process fractures and to identify factors that might influence the outcome. Thirteen male patients (mean age 35 years; range 17 to 53 years) were treated with open reduction and internal fixation for displaced coronoid fractures. According to the Regan-Morrey classification, the fractures were type 2 in nine patients (69.2%), and type 3 in four patients (30.8%). Nine patients had associated injuries (elbow dislocation, radial head or olecranon fractures, and/or ligamentous injuries). The mean duration to treatment was 2.3 days (range 1 to 7 days). Functional results were assessed according to the Mayo elbow performance score (MEPS), and signs of arthritis were assessed according to the Broberg-Morrey criteria. The mean follow-up was 41.1 months (range 12 to 96 months). A functional range of motion of the elbow joint was achieved in 10 patients (76.9%). The mean elbow range of motion was 110.7 degrees (range 85 degrees to 130 degrees ) and the mean forearm rotation was 134.2 degrees (range 120 degrees to 155 degrees ). Three patients who had comminuted fractures and associated elbow injuries had decreased range of motion. None of the patients exhibited signs of instability. The mean MEPS was 86.5 (range 75 to 100). The results were excellent in four patients (30.8%; the mean MEPS 98.8) having isolated or noncomminuted coronoid fractures, and good in nine patients (69.2%) with comminuted fractures and/or associated bone or ligament injuries. Post-traumatic arthritis was detected in seven patients (53.9%) whose mean MEPS was 81.4. Patients with an excellent functional result did not develop arthritis. All the patients returned to preinjury activity levels. Coronoid fractures are the most important component of complex elbow injuries. The presence of comminuted fractures, associated bone and ligament injuries, and post-traumatic arthritis affect the outcome adversely.
