Aims. Fixation techniques used in the treatment of slipped capital femoral epiphysis (SCFE) that allow continued growth of the femoral neck, rather than inducing epiphyseal fusion in situ, have the advantage of allowing remodelling of the deformity. The aims of this study were threefold: to assess whether the Free-Gliding (FG)
Controversy remains as to whether the contralateral hip should be fixed in patients presenting with unilateral slipped capital femoral epiphysis (SCFE). This study compares the outcomes of those patients who had prophylactic fixation with those who did not. We identified 90 consecutive patients with a mean age of 12.3 years presenting to the study centre with
We present the results of a prospective study about twenty-nine patients (thirty-two hips) with unstable slipped capital femoral epiphysis (SCFE), which were treated by indirect reduction and internal fixation of the epi- and metaphysis with 3–4 Kirschner-wires between 1990 – 1999. Methods: The 29 patients with a mean age of 12,9 years were clinically and radiologically evaluated after a mean follow-up of 3 years applying the score of Heymann and Herndon and by different roentgenological parameters (CCD-angle, femoral head diameter, length of the femoral neck and sphericity of the femoral head). Compared to the uninvolved side in unilateral case, which all had prophylactic pinning, all patients showed overall a good subjective and objective outcome. The average slip angle of all 29 unstable

Methods. A retrospective review of 80 patients with unilateral slipped capital femoral epiphysis from 1998–2012 was undertaken to determine the outcome of the unaffected hip. All patients were treated with either prophylactic single Richards screw fixation or observation of the uninvolved hip and were followed up for at least 12 months. The unaffected hip of 44 patients (mean age 12.6 years, range 9–17) had simultaneous prophylactic fixation and 36 patients (mean age 13.4 years, range 9–17.4) were managed with observation. Results. Sequential slip of the unaffected hip was noted in 10 patients (28 per cent) in the observation group and only in 1 patient (2 per cent) in the group managed with prophylactic fixation. A Fisher's exact test showed significantly high incidence of sequential slip in unaffected hips when managed with regular observation (p-value 0.002). Only 3 cases had symptomatic hardware on the unaffected side after prophylactic fixation with one requiring revision of the metal work; one had superficial wound infection treated with antibiotics. No cases had AVN or chondrolysis. Conclusion. Simultaneous prophylactic fixation of the unaffected hip significantly reduces the incidence of sequential slip in unilateral
Aims. We aimed to assess the cumulative risk of total hip arthroplasty (THA) from in situ fixation for slipped capital femoral epiphysis (SCFE) after a follow-up of almost 50 years. Methods. In this study, 138 patients with 172 affected hips treated with in situ fixation were evaluated retrospectively. A total of 97 patients (70%) were male and the mean age was 13.6 years (SD 2.1); 35 patients (25%) had a bilateral disease. The median follow-up time was 49 years (interquartile range 43 to 55). Basic demographic, stability, and surgical details were obtained from patient records. Preoperative radiographs (slip angle; SA) were measured, and data on THA was gathered from the Finnish National Arthroplasty Register. Results. The preoperative SA was a mean of 39° (SD 19°). At follow-up, 56 of the patients had undergone THA for a hip previously fixed in situ for

Anatomic reduction (subcapital re-alignment osteotomy) via surgical hip dislocation – increasingly popular. While the reported AVN rates are very low, experiences seem to differ greatly between centres. We present our early experience with the first 29 primary cases and a modified fixation technique. We modified the fixation from threaded Steinman pins to cannulated 6.5mm fully-threaded screws: retrograde guidewire placement before reduction of the head ensured an even spread in the femoral neck and head. The mean PSA (posterior slip angle) at presentation (between 12/2008 and 01/2011) was overall 68° (45–90°). 59% (17/29) were stable slips (mean PSA 68°), and 41% (12/29) were unstable slips unable to mobilise (mean PSA 67°). The vascularity of the femoral head was assessed postoperatively with a bone scan including tomography. The slip angle was corrected to a mean PSA of 5.8° (7° anteversion to 25° PSA). We encountered no complications related to our modified fixation technique. All cases with a well vascularised femoral head on the post-operative bone scan (15/17 stable slips and 8/12 unstable slips) healed with excellent short term results. Both stable slips with decreased vascularity on bone scan (2/17, 12%) had been longstanding severe slips with retrospectively suspected partial closure of the physis, which has been described as a factor for increased risk of avascular necrosis (AVN). One of these cases was complicated by a posterior redislocation due to acetabular deficiency. In the unstable group, 4/12 cases (33%) had avascular heads intra-operatively and cold postoperative bone scans, 3 have progressed to AVN and collapse. Anatomic reduction while sparing the blood supply of the femoral head is a promising concept with excellent short term results in most stable and many unstable
We present our experience of the modified Dunn
procedure in combination with a Ganz surgical dislocation of the hip
to treat patients with severe slipped capital femoral epiphysis
(SCFE). The aim was to prospectively investigate whether this technique
is safe and reproducible. We assessed the degree of reduction, functional
outcome, rate of complications, radiological changes and range of
movement in the hip. There were 28 patients with a mean follow-up
of 38.6 months (24 to 84). The lateral slip angle was corrected
by a mean of 50.9° (95% confidence interval 44.3 to 57.5). The mean
modified Harris hip score at the final follow-up was 89.1 (. sd. 9.0)
and the mean Non-Arthritic Hip score was 91.3 (. sd. 9.0).
Two patients had proven pre-existing avascular necrosis and two
developed the condition post-operatively. There were no cases of
nonunion, implant failure, infection, deep-vein thrombosis or heterotopic ossification.
The range of movement at final follow-up was nearly normal. This
study adds to the evidence that the technique of surgical dislocation
and anatomical reduction is safe and reliable in patients with
In situ fixation of mild slips of the slipped capital femoral epiphysis (SCFE) is a safe and reliable method of treatment. Hardware failure and fractures are reported at the time of pin retrieval. Difficulty in removing these pins is well reported. Major problems can be expected when arthroplasty is necessary years later, if the pins are still inside the proximal femur. Hence we have come up with a novel technique to remove these pins during Primary Total hip arthroplasty. The hip is exposed through posterior approach, dislocated and the neck is then cut at the usual site. It is then segmented in both sagittal and coronal planes into approximately eight to ten pieces and removed piecemeal. The pins are thus exposed, cleared of any bony debris and hammered retrograde. By using our simple and novel technique to remove these pins we feel it avoids unnecessary trauma to the outer cortex of femur and also reduces the operating time significantly.
Introduction and Objective. Slipped Capital Femoral Epiphysis (SCFE) is one of the most common hip disorders in children and is characterized by a proximal femoral deformity, resulting in early osteoarthritis. Several studies have suggested that
Aims. The modified Dunn procedure has the potential to restore the anatomy in hips with severe slipped capital femoral epiphyses (SCFE). However, there is a risk of developing avascular necrosis of the femoral head (AVN). In this paper, we report on clinical outcome, radiological outcome, AVN rate and complications, and the cumulative survivorship at long-term follow-up in patients undergoing the modified Dunn procedure for severe
