Open intramedullary Kirschner wire versus screw and plate fixation for unstable forearm fractures in children

Purpose. To compare the outcomes of intramedullary Kirschner wire versus screw and plate fixation for unstable forearm fractures in children aged older than 10 years. Methods. Records of 32 children aged 10 to 15 (mean, 12) years with displaced fractures of the radius and ulna were retrospectively reviewed. 17 boys and 4 girls underwent intramedullary Kirschner wiring, whereas 10 boys and one girl underwent plating. All patients had been initially treated with closed reduction and casting. Indications for surgical intervention were fractures with angulation of >10° and total displacement. Patients were followed up for a mean of 24 (range, 13–40) months. Angulation and range of movements of the elbow, wrist, and forearm, as well as clinical and cosmetic results were compared. Results. Both treatments achieved excellent clinical outcomes, but intramedullary Kirschner wiring resulted in better cosmesis, shorter operating times, easier hardware removal, and lower implant costs. Conclusion. Intramedullary Kirschner wiring is a better option than plating for the treatment of unstable forearm fractures in older children.

Injection of autologous blood versus corticosteroid for lateral epicondylitis: a randomised controlled study

Purpose. To compare the efficacy of autologous blood injection versus corticosteroid injection for lateral epicondylitis. Methods. 21 men and 59 women (mean age, 45.2 years) presenting with lateral epicondylitis were randomised to receive either autologous blood injection (2 ml of autologous venous blood mixed with 1 ml of 2% prilocaine hydrochloride) or corticosteroid injection (1 ml of 40 mg methylprednisolone acetate mixed with 1 ml of 2% prilocaine hydrochloride) given by a single physician. Patients were assessed before (day 0) and after (days 15, 30, and 90) treatment for elbow pain (using a visual analogue scale [VAS]), function (using the patient-rated tennis elbow evaluation [PRTEE] questionnaire), and grip strength (using a hydraulic hand dynamometer). Patients were followed up at 6 months by telephone to assess elbow pain using the VAS. Results. No complications (infection, skin atrophy, neurovascular damage, or tendon rupture) were noted. 10 patients reported increased pain for up to 2 days after autologous blood injection. In both groups, the VAS score for elbow pain, PRTEE score, and grip strength improved significantly after treatment (p=0.0001), but the pattern of improvement differed. Compared with autologous blood injection, corticosteroid injection improved all 3 scores at a faster rate over the first 15 days (p=0.0001), and then started to decline slightly until day 90. After autologous blood injection, all 3 scores improved steadily and were eventually better (p=0.0001). If a 37% decrease in PRTEE is defined as complete recovery, 38 (95%) of patients with autologous blood injection and 25 (62.5%) of patients with corticosteroid injection achieved complete recovery (p=0.0001). Conclusion. Autologous blood injection was more effective over the follow-up period than corticosteroid injection in improving pain, function, and grip strength. It is recommended as a first-line injection treatment because it is simple, cheap, and effective.

Prevention of proximal junctional kyphosis after posterior surgery of Scheuermann kyphosis: an operative technique.

Study Design: A prospective randomized study. Objective: To introduce an operative technique that prevents proximal junctional kyphosis (PJK) in Scheuermann disease after a segmental posterior spinal instrumentation and fusion. Summary of Background Data: PJK is the progression of kyphotic deformity at the proximal end of a construct >10 degrees, and it can be seen up to 30% after posterior Scheuermann kyphosis surgery. After posterior fusion the biomechanics of the spine changes and the loss of motion at the fused levels is compensated by increased motion at other unfused segments. As a result significant amount of additional force is placed on the proximal junction. With our operative technique, we aimed to have a smooth passage from rigid to mobile segments and to decrease the stress on proximal junction during cantilever reduction to prevent PJK. Methods: A total of 60 consecutive patients (mean age: 18.27±3.19, male/female: 28/32) who were surgically treated for Scheuermann kyphosis in our institution were recruited into this study and were prospectively evaluated. Patients were divided into 2 groups according to upper-most screw fixation technique. In group 1, a standard screw insertion technique was used (ST group). The technique was modified in group 2 (MT group), leaving 2 threads out of the posterior cortex. There were 29 patients in group 1 (ST) and 31 patients in group 2 (MT). Patients had an average follow-up time of 24.2 months (range, 19–48 mo). Evaluated radiographic parameters were preoperative and postoperative kyphosis angle, and proximal junctional angle (PJA) at last visit. PJA was defined as the angle between the caudal endplate of the upper instrumented vertebra and the cephalad endplate of 2 suprajacent vertebrae above the upper instrumented vertebra. PJA exceeding 10 degrees was accepted as PJK. Quality of life measurement was assessed preoperatively and postoperatively with SF-36 questionnaire. Results: Correction amounts in ST group and MT group were 46.8% and 43.7%, respectively, which was statistically insignificant. The mean PJA was 8.08±2.96 degrees and 4.44±1.55 degrees in ST and MT groups, respectively, which demonstrated a statistically significant difference (P=0.001). Five patients in ST group had a PJA exceeding 10 degrees (PJK), whereas PJK was not seen in MT group (P=0.022). The improvement in physical component summary of SF-36 was significantly better in MT group; however, mental component summary was similar in both groups. Conclusions: This study introduces a new technique that may have an effect in preventing PJK. Our results seem to be satisfactory, but additional studies with more patients and longer follow-up times are needed to further delineate the feasibility of this technique.

Traction apophysitis of the fifth metatarsal base in a child: Iselin's disease

Although Iselins disease, apophysitis of the fifth metatarsal base, is not infrequent in clinical practice, it is accepted as a rare cause of lateral foot pain in young adolescents. Usually a simple clinical examination and radiographs are sufficient for diagnosis. We present a patient with Iselins disease and discuss its clinical and radiographic characteristics, differential diagnosis, aetiopathogenesis and treatment.
