3 Déficit Neurológico Meta-análisis 5154 fracturasFracturas en extensión 13% (34% Interóseo anterior, luego radial y mediano) Fracturas en flexión 17% (91% cubital). Algunas series de las fx en exension reportan como mas comun la lesion del radial.. Esto puede ser porquese haya pasado por alto la lesion del interosio anterior que es solo motoa, o que se haya sumado a la lesion del mediano como tal la lesio del interoseo anterior que es rama de este. Babal JC, Mehlman CT, Klein G. Nerve injuries associated with pediatric supracondylar humeral fractures: a meta-analysis. J Pediatr Orthop 2010;30: Pooled data from 5,148 patients and 5,154 fractures was used in this study. There was a 13% rate of pre-operative neurapraxia for extension-type fractures (most common injured nerve was AIN – 34% of cases) and a 17% rate in flexion-type fractures (most common injured nerve was ulnar nerve – 91% of cases). Medial [distal] entry carried a 4% risk to the ulnar nerve and lateral [distal] entry conveyed a 3% risk of median nerve injury. Babal JC, Mehlman CT, Klein G.

Usualmente resuelven espontáneamente Retiro del pin si en los Rx. se ve en la escotadura troclear Recomienda explorar y no solo retirar el pin Lyons JP, Ashley E, Hoffer MM: Ulnar nerve palsies after percutaneous cross-pinning of supracondylar fractures in children's elbows. J Pediatr Orthop 1998; 18(1): Royce RO, Dutkowsky JP, Kasser JR, Rand FR: Neurologic complications after K-wire fixation of supracondylar humerus fractures in children. J Pediatr Orthop 1991; 11(2): 4 of 143 supracondylar fractures treated with K-wire fixation had neurologic complications after treatment. There were two late ulnar neurapraxias, and two direct nerve injuries during K-wire insertion, one to the ulnar and one to the radial nerve. All patients ecovered. The importance of a thorough initial neurological and vascular examination, as well as subsequent examinations immediately after treatment and during recovery is emphasized. Quoted a 2-3% incidence of iatrogenic nerve injury in displaced supracondylar umerus fractures. Lyons JP, Ashley E, Hoffer MM: Ulnar nerve palsies after percutaneous cross-pinning of supracondylar fractures in children's elbows. J Pediatr Orthop 1998; 18(1): Of 375 supracondylar humerus fractures treated over 4 year period by closed or open reduction and percutaneous pinning, 19 patients with normal preoperative neurologic examinations developed postoperative ulnar nerve palsies. 17 patients were followed and all had complete return of function, although complete return of function took up to 4 months. Only 4 patients had medial pins removed prior to fracture union, and 2 others had exploration of the ulnar nerve demonstrating no interruption. The authors state that postoperative ulnar nerve palsies usually resolve spontaneously, and they believe that in most cases of postoperative ulnar nerve palsy observation is ppropriate. If the medial pin appears radiographically to be positioned in the ulnar notch, it may be appropriate to remove it and replace it more anteriorly if the pin is needed for stabilization of the fracture. Rasool MN: Ulnar nerve injury after K-wire fixation of supracondylar humerus fractures in children. J Pediatr Orthop 1998; 18(5): 6 cases of postoperative ulnar nerve palsy after cross pin fixation are described. Pain on extension of the small and fingers, and early clawing were important postoperative signs of ulnar nerve injury. Exploration revealed pin placement in the cubital tunnel in 5/6, in 2 the nerve was directly penetrated, and in 3 the cubital retinaculm was tethered and stretched tightly over the nerve. In the 6th case the nerve was anteriorly subluxated and fixed anterior to the medial epicondyle by the pin. After exploration and nerve decompression, 3 fully recovered, 2 partially recovered and one patient had no recovery. The author recommends exploration rather than simple pin removal.

Eur J Vasc Endovasc Surg 2008;36: Traditional review paper of the pulseless yet perfused hand. The authors conclude that angiography is of little use and that color flow duplex imaging deserves further study. The authors recommend exploration if signs of ischemia are present. Schoenecker PL, Delgado E, Rotman M, Sicard GA, Caplli AM: Pulseless arm in association with totally displaced supracondylar fracture. J Orthop Trauma 1996; 10(6): Over a 12 year period, seven children had a pulseless arm and a seemingly viable hand after reduction and pinning of a type III supracondylar humerus fracture. 6 of 7 had no pulse prior to reduction. 4 had closed reduction while 3 had an open reduction. 6 patients underwent immediate exploration of the antecubital fossa, while one had arteriography followed by exploration (In discussion authors note arteriography is not helpful in these cases).The brachial artery was directly damaged or transected and underwent saphenous vein graft repair in 3 cases, and was entrapped in the fracture and dissected free in 4 cases. Distal pulses were reestablished in each case, and long term outcome was good. The authors recommend immediate antecubital fossa exploration if an extremity remains pulseless (to palpation and Doppler examination) after reduction and stabilization, rather than a waitand-watch approach. Shaw BA, Kasser JR, Emans JB, et al: Management of vascular injuries in displaced supracondylar humerus fractures without arteriography. J Orthop Trauma 1990; 4:25-29. 17 of 143 (11.9%) type III fractures had signs of vascular impairment, and reduction and Kwire fixation resulted in return of satisfactory blood supply in 14 of 17. The other three were treated with exploration of the brachial artery. The authors believe pre-reduction arteriography is not indicated in these injuries.

J Pediatr Orthop 1996; 16: 22 of 326 patients with supracondylar humerus fractures presented without a radial pulse. 15 of 22 had a well perfused hand after closed reduction. 5 had a well perfused hand but no pulse, and none had any problem at final review. Seven patients had a cold white hand after closed reduction and pinning, and received open reduction and arterial exploration. The authors concluded that an absent radial pulse after closed reduction does not require routine exploration if the hand is well-perfused.

Underreduced supracondylar fracture of the humerus in children: clinical significance at skeletal maturity. J Pediatr Orthop 2007;27: This paper addresses issues related to sagittal and coronal alignment of supracondylar humeral fxs. These Israeli authors reviewed 223 supracondylar pts between 1996 and 2000 and found 30 that were underreduced. 73% (22/30) were followed until skeletal maturity or close to skeletal maturity. At final follow-up 77% were more than 5 degrees off on their Baumann’s angle (as compared to the opposite side), and 50% had limited elbow flexion. The abnormalities were such that only 31% of pts were aware of any difference in their elbows. The authors recommend achieving maximal anatomical position in the coronal and sagittal planes

Delay increases the need for open reduction of type-III supracondylar fractures of the humerus. J Bone Joint Surg-Br2006; 126 pts > 8h < 8h Walmsley PJ, Kelly MB, Robb JE, Annan IH, Porter DE. Delay increases the need for ffffffffffffffffffffffffffffffffffffffff open reduction of type-III supracondylar fractures of the humerus. J Bone Joint Surg-Br 2006; 126 pts treated early (< 8 hrs) were compared to 45 who had delayed treatment (> 8 hrs). No significant differences in complication rates were identified. A very high rate of open reduction was noted in both groups – an 11% rate in the early group and a 33% rate in the delayed group. These authors recommended treating such supracondylars at the earliest opportunity.

27 Momento del tratamientoEmergente, urgente o electivo? 158 fracturas tipo 3 21 fracturas antes de 8 horas Promedio para todos 21 horas No hubo correlación en malos resultados, complicaciones y tiempo operatorio con el tiempo de evolución antes de cirugía.

J Pediatr Orthop 2002;22: Estudio con evidencia debil pero no se uede rendomizar por cuetiones eticas. Leet A, Frisancho J, Ebramzadeh E. Delayed treatment of type 3 supracondylar humerus fractures in children. J Pediatr Orthop 2002;22: Retrospective review of 158 type III fractures did not find any correlation between length of time between injury and surgical treatment with regard to increased operative time, need for open reduction, length of hospital stay or unsatisfactory result. 5 children had a nerve injury identified on initial examination, and no arm was poorly perfused. The average time from injury to surgery was 21.3 hours. 30 patients had poor results (>15 degrees loss of motion -17, pin tract infection-1, pin migration requiring general anesthetic for removal -1, malunion – 2 cubitus varus, postoperative neurapraxias -8 ulnar and 1 median). All nerve injuries resolved by 6 month follow-up. Delayed treatment is equivalent to emergent treatment in closed type III fractures with no associated neural or vascular injuries.

Early versus delayed treatment of extension type-3 fffffffffffffffffffffffffffffffffffff supracondylar fractures of the humerus in children. J Bone Joint Surg-Br 2006;88:380- 381. 43 children whose type III fractures were treated within 12 hrs of injury were compared to 34 children treated greater than 12 hrs following injury. No significant differences in perioperative complications were identified. The authors concluded that uncomplicated supracondylar fxs could be treated early or delayed.

Relationship of the anterior humeral line to the capitellar ossific nucleus: variability with age. J Bone Joint Surg 2009;91-A: Three observers measured 30 x-rays on two occasions for this study. The anterior humeral line passed thru anterior or middle third of the capitellum in 83% of pts. In children younger than 4 years of age the line tends to be “more anterior” and in older children the line tends to pass thru the central third of the capitellar center.

Six cases of lateral condylar fracture of the humerus in children with preexisting cubitus varus due to prior elbow fracture are presented. Biomechanical analysis suggests that both the torsional moment and the shear force generated across the capitellar physis by a routine fall are increased by varus malalignment. Posttraumatic cubitus varus may predispose a child to subsequent lateral condylar fracture and should be viewed as more than just a cosmetic deformity.

Postoperative stiffness was not common, as only six patients had loss of extension of 10 degrees or more. The surgical approach was made through the torn soft tissues without further destabilizing or devascularizing the fracture. Open reduction is indicated for fractures irreducible by closed means, open fractures, fractures associated with vascular compromise, and fractures with a postreduction nerve palsy when anatomic reduction is not obtainable.

In 10 cases vascular impairment or unsatisfactory reduction necessitated open exploration. Functional and cosmetic success was achieved in 90% of all operated children. In 33 (16.5%) there was neurological impairment. All recovered without sequelae, except for one case. Transient Neurological problems are common in this fracture.

J Pediatr Orthop 2002;22: This study evaluated forearm compartment pressures in 29 children with supracondylar humerus fractures. The effect of elbow flexion on post-reduction pressures was also evaluated; flexion beyond 90° produced significant pressure elevation. We conclude that forearm pressures after supracondylar fracture are greatest in the deep volar compartment and closer to the fracture site. To avoid unnecessary elevation of pressures, elbows should not be immobilized in >90° of flexion after these injuries. Mapes R, Hennrikus W.

J Pediatr Orthop 1998;18: After closed reduction and percutaneous K-wire fixation of displaced extension supracondylar fractures, vascular safety is enhanced by extending the elbow and supinating the forearm.

Risk factors for vascular repair and compartment syndrome in the pulseless supracondylar humerus fracture in children. J Pediatr Orthop 2010;30:50-56. These Southern California researchers determined that 2.6% (33/1,255) supracondylar fx pts present without a pulse. 24 of the pts were considered to be pulseless and well perfused at presentation and 100% (24/24) remained well perfused immediately following reduction and internal fixation while 58% (14/24) were also noted to have a palpable pulse following reduction and internal fixation. At an average of 8 week f/u at least 4 more of these pts had a palpable pulse documented, THUS 75% (18/24) of the perfused and pulseless normalized following reduction and fixation. The other 6 perfused and pulseless pts who never had a documented return of pulse suffered no known ill effects of their injury. Only 2 of 9 of the pulseless and POORLY perfused pts had both return of perfusion and pulse following reduction and fixation. Another 2 of 9 pts had satisfactory perfusion but no immediate palpable pulse after CRPP surgery. The other 5 of 9 pts were all explored / repaired with good results. Perfused and pulseless pts were operated at an avg of 10.7 hrs (range 4 h to 24 h) following injury while the pulseless and poorly perfused pts were operated at an avg of 7.3 hrs (range 3 hrs to 12 hrs) following injury. THIS IMPORTANT PAPER TELLS US THAT A SIGNIFICANT PERCENTAGE OF PULSELESS PTS IMPROVE FOLLOWING REDUCTION AND FIXATION.

Vascular injuries and their sequelae in pediatric supracondylar humeral fractures: Toward a goal of prevention. J Pediatr Ortho 1996;16:99-103 17 of 128 consecutive children with type III supracondylar humeral fractures had absent or diminished (detected with Doppler but not palpable) radial pulses on initial examination. Fourteen of these 17 children recovered pulse (palpable) after reduction and stabilization of their fractures. The remaining three had persistent absence of radial pulse. Each was explored immediately and found to have a significant vascular injury requiring repair. Two of the 14 children who had initially regained their pulses had a progressive postoperative deterioration in their circulatory status during the first h, including loss of the radial pulse. Both had arteriograms that identified vascular injuries and underwent exploration and bypass grafting. One of these two children had been transferred 48 h after injury, resulting in delay of management of his vascular impairment. Despite exploration, vascular repair, and fasciotomy, he ultimately developed Volkmann's ischemic contracture. Immediate reduction and fixation followed by careful evaluation and treatment of ischemia were associated with excellent outcome in four of the five children.

Percutaneous pinning provided the highest number of good results and is recommended as the treatment of choice for most fractures. Skeletal traction, however, provided acceptable results in some patients who had significant soft-tissue swelling.
