Z-Plasty for Severe Gluteal Muscle Contracture in Children

Purpose To review the records of 363 patients with severe gluteal muscle contracture to determine its mechanism, underlying pathology, and treatment outcome. Methods Records of 136 males and 227 females aged 5 to 18 (mean, 12.2) years who underwent Z-plasty for bilateral (n=347) or unilateral (n=16) severe gluteal muscle contracture were reviewed. Severe gluteal muscle contracture was classified as typical (n=52) or special (n=311). The typical type is associated with symptoms of positive out-toe gait, Ober sign, back-extending test, cross-leg test, squatting with knee side-by-side test, and hip dysfunction. It is further subdivided into mild (n=0), moderate (n=40), or severe (n=12). The special type is associated with additional symptoms of pelvic tilt and leg length discrepancy (<2 cm in 181 hips, 2–4 cm in 82 hips, and >4 cm in 48 hips). 311 hips had pelvic tilt and 47 hips had lumbar compensatory scoliosis. Treatment outcome was assessed at 6 months. Hip functional score was assessed at the final follow-up. Results The mean hospitalisation period was 11 days. After a mean follow-up of 1.5 years, the mean hip functional score improved from 8.03 to 11.69; improvement was higher in children (age 5–13 years) than in adolescents (age 14–18 years) [3.7 vs. 2.9, p<0.001]. At 6 months, outcome was excellent in 280 hips, good in 80, fair in 3 hips, and poor in 0. The 3 hips with fair outcome had persistent slight pelvic tilt and swaying gait. Two of them had preoperative leg length discrepancy >4 cm, and intra-operatively the contracture band severely affected the joint capsule. The third patient did not comply with postoperative exercises. Conclusion Surgical treatment for severe gluteal muscle contracture achieved good outcome.

AimsThe aim of this study was to describe, analyze, and compare the survival, functional outcome, and complications of minimally invasive (MI) and non-invasive (NI) lengthening total femoral prostheses.Patients and MethodsA total of 24 lengthening total femoral prostheses, 11 MI and 13 NI, were implanted between 1991 and 2016. The characteristics, complications, and functional results were recorded. There were ten female patients and ten male patients. Their mean age at the time of surgery was 11 years (2 to 41). The mean follow-up was 13.2 years (seven months to 29.25 years). A survival analysis was performed, and the failures were classified according to the Modified Henderson System.ResultsThe overall implant survival was 79% at five, ten, and 20 years for MI prostheses, and 84% at five years and 70% at ten years for NI prostheses. At the final follow-up, 13 prostheses did not require further surgery. The overall complication rate was 46%. The mean revision-free implant survival for MI and NI prostheses was 59 months and 49 months, respectively. There were no statistically significant differences in the overall implant survival, revision-free survival, or the distribution of complications between the two types of prosthesis. Infection rates were also comparable in the groups (9% vs 7%; p = 0.902). The rate of leg-length discrepancy was 54% in MI prostheses and 23% in NI prostheses. In those with a MI prosthesis, there was a smaller mean range of movement of the knee (0° to 62° vs 0° to 83°; p = 0.047), the flexion contracture took a longer mean time to resolve after lengthening (3.3 months vs 1.07 months; p < 0.001) and there was a lower mean Musculoskeletal Tumor Society (MSTS) score (24.7 vs 27; p = 0.295).ConclusionThe survival and complications of MI and NI lengthening total femoral prostheses are comparable. However, patients with NI prosthesis have more accurate correction of leg-length discrepancy, a better range of movement of the knee and an improved overall function.

Abstract Background To compare the outcomes of debridement and antibiotic-loaded spacer implantation in primary advanced septic arthritis (SA) of the hip in adults treated with two-stage total hip arthroplasty (THA). Methods In the first stage, 9 patients were treated with debridement and 11 patients were treated with antibiotic-loaded spacer implantation. Then, THA was conducted in all patients in the second stage. Patients were evaluated based on the recurrence of infection, Harris hip score, visual analogue scale (VAS) pain score and leg-length discrepancy. Results No cases of infection, deep vein thrombosis, death, and loosening of hip prosthesis were observed during follow-up. The mean follow-up time was 29.09 ± 10.80 months in the debridement with THA group, and 28.22 ± 14.80 months in the spacer implantation with THA group. Before the THA surgery, the mean leg-length discrepancy was 2.80 ± 2.03 cm in the debridement with THA group, and 0.50 ± 0.23 cm in the spacer implantation with THA group (P < 0.05). In the latest follow-up, The Harris hip scores of patients was 90.33 ± 4.85 in the debridement with THA group and 94.36 ± 2.34 in the spacer implantation with THA group (P < 0.05), respectively. There was no statistical significant difference in VAS pain score of the hip between the two groups (P > 0.05).Conclusions Two-stage THA using antibiotic-loaded spacer implantation is an effective method for the treatment of advanced SA of the hip in adults due to it can control infection and significantly improve functional hip.

Primary Bone Tumours

Aims The use of a noninvasive growing endoprosthesis in the management of primary bone tumours in children is well established. However, the efficacy of such a prosthesis in those requiring a revision procedure has yet to be established. The aim of this series was to present our results using extendable prostheses for the revision of previous endoprostheses. Patients and Methods All patients who had a noninvasive growing endoprosthesis inserted at the time of a revision procedure were identified from our database. A total of 21 patients (seven female patients, 14 male) with a mean age of 20.4 years (10 to 41) at the time of revision were included. The indications for revision were mechanical failure, trauma or infection with a residual leg-length discrepancy. The mean follow-up was 70 months (17 to 128). The mean shortening prior to revision was 44 mm (10 to 100). Lengthening was performed in all but one patient with a mean lengthening of 51 mm (5 to 140). Results The mean residual leg length discrepancy at final follow-up of 15 mm (1 to 35). Two patients developed a deep periprosthetic infection, of whom one required amputation to eradicate the infection; the other required two-stage revision. Implant survival according to Henderson criteria was 86% at two years and 72% at five years. When considering revision for any cause (including revision of the growing prosthesis to a non-growing prosthesis), revision-free implant survival was 75% at two years, but reduced to 55% at five years. Conclusion Our experience indicates that revision surgery using a noninvasive growing endoprosthesis is a successful option for improving leg length discrepancy and should be considered in patients with significant leg-length discrepancy requiring a revision procedure.

AbstractThe best surgical choice for distal femur osteosarcoma in skeletally immature patients remains controversial. A fixed hinged knee prosthesis has been designed to preserve the growth plates in the adjacent tibia, expecting tibial growth to be continued. This study aims to report the (1) clinical outcomes after prosthetic replacement, (2) postoperative complications, and (3) length of discrepancy of the operative tibia with the unaffected tibia. Thirty-four skeletally immature patients (averaged 9 years at surgery; range, 5–12 years) with distal femoral osteosarcoma underwent placement of this hinged knee prosthesis between January 2015 and August 2018. Postoperative function and complications were assessed. Length discrepancy was measured using a series of full-length standing anteroposterior radiographs of the bilateral lower extremity. The average follow-up duration was 34 months (2.8 years). In the last follow-up, four patients expired because of pulmonary metastasis. Two patients presented with local recurrence of the soft tissue. Postoperatively, the flexion range of the knee joint range was between 100 and 130 degrees, with an average of 115.2 degrees. The mean functional score of living patients evaluated using the Musculoskeletal Tumor Society scoring system was 89.2% (range, 76.7–100%). Types 1 (three patients), 2 (one patient), 3 (two patients), and 5 (two patients) complications exist. Among them, three patients received revision surgery. The proximal tibial physis still grew after surgery, with an average of 74.3% (range, 30–100%) growth potential compared with the unaffected proximal tibial physis. Moreover, 27 children exhibited tibial length discrepancy compared with the contralateral tibia, and the mean discrepancy in tibial length was 1.1 cm (range, 0.2–3.1 cm). This hinged knee prosthesis can keep the growth potential in the adjacent tibia, provides satisfying functional outcomes, and has a lower postoperative complication rate. Thus, it could serve as an alternative intervention for distal femoral osteosarcoma in skeletally immature patients.

The aim of our study was to review the long term clinical and radiological (MRI) outcomes of adult patients who underwent ACL reconstruction as children or adolescent with emphasize to the features of growth disturbance, angular deformity, meniscal and cartilage damage and revision rate We retrospectively evaluated patient who underwent ACL reconstruction in our clinic with arthroscopic transepiphyseal technique using hamstrings graft in childhood or adolescence between the years 1997 and 2009. A total of 43 Patients were assessed. 25 male and 18 female. The average age at time of surgery was 13,5 years (8 - 16 y.), at time of assessement 22,4 years (18 - 30 y.) . The mean follow up was 10 years (4 - 16 years). The physical development of the patients was assessed with the Lysholm score and the Cincinnati Knee score scale, their satisfaction was recorded on the basis of the IKDC subjective knee evaluation form and the Tegner activity score . Leg deformity or leg length discrepancy was evaluated clinically by the observers. The instrumented Lachman test using KT1000 and manual Pivot shift test was performed to assess knee stability. MRI was used to detect graft integrity, cartilage and meniscal damages. No significant leg deformities or leg length discrepancy had been detected. The average Lysholm score was 91 points (83 - 100), the Cincinnati Knee Score was 90,4 (79 - 100) points on average . The mean IKDC score was 92 points (82 -100). The Tegner-Activity-Score changed from preop 6,8 (2-10) to post op 5,8 (2-9). 2 Patient underwent revision ACL reconstruction due to rerupture (3 and 9 years post op). 2 Patients underwent meniscal surgery during follow up (1 resection and one refixation). KT1000 evaluation showed 67% excellent, 21% good and in 12% bad results. The MRI scan showed 42 intact grafts and one unverifiable graft. One patient with cartilage damage up to 3° (ICRS), 3 patients with meniscal degeneration up to grade 2. Each patient showed a free range of motion Our data underlines that transepiphyseal ACL reconstruction in children and adolescent with hamstrings is a save procedure leading to good long term results without causing angular deformity or growth disturbance

Purpose To compare two common surgical techniques of epiphysiodesis: drill/curettage epiphysiodesis (PDED) versus cross screw epiphysiodesis (PETS). The hypothesis is that the two techniques have similar efficacy but demonstrate differences in length of hospital stay (LOS), time to return to activity and complication rates. Methods A retrospective review of growing children and adolescents less than 18 years old who required an epiphysiodesis with leg-length discrepancy (LLD) of 2 cm to 6 cm with minimum two years of follow-up was conducted. Characteristics including age at surgery, gender, epiphysiodesis location, side, operative time, LOS and hardware removal were compared across treatment groups. LLD, expected growth remaining (EGR) and bone age were determined preoperatively and at most-recent visit. The correction ratio (change in EGR) was calculated along with a 95% confidence interval (CI) to assess if correction in leg length was achieved. Results A total of 115 patients underwent epiphysiodesis in the femur (53%), tibia (24%) or a combination (24%). The cohort was 47% male, with a mean age of 12.6 years (7.7 to 17.7) at surgery. Median follow-up was 3.7 years (2.0 to 12.7). In all, 23 patients underwent PETS and 92 patients had PDED. Both treatment groups achieved expected LLD correction. There was no significant difference in median operative time, complication rates or LOS. PETS patients returned to activity at a mean 1.4 months (interquartile range (IQR) 0.7 to 2.1) while PDED patients returned at a mean 2.4 months (IQR 1.7 to 3) (p < 0.001). Conclusion Effectiveness in achieving expected correction, LOS and operative time are similar between screw and drill/curettage epiphysiodesis. Patients undergoing PETS demonstrated a faster return to baseline activity than patients with PDED. Level of Evidence: III

Background: Planter fasciitis, is by definition, inflammation of planter fascia. Most of the cases are well treated conservatively and a few responds to surgery only. Objectives of present study were evaluating the efficacy of a single injection of leukocyte free platelet rich plasma in plantar fasciitis and to derive a correlation between the clinical and radiological outcome.Methods: The present study consisted of 120 patients of bilateral (PF), (240 feet). These patients were divided into two groups PRP group of 60 patients and Placebo group of 60 patients. The study was conducted on patients attending Orthopaedics outpatient department Post Graduate Institute of Medial Education and Research (PGIMER) from July 2011 to June 2012. A primary efficacy criterion was changes from baseline in pain using (VAS). Functional results, level of satisfaction and outcome were measured by – AOFAS Foot Scale. Correlation of clinical with radiological outcome were performed.Results: There was a significant decrease in the visual analogue scale (pain score) in the PRP. Group while in placebo group it was increased significantly at the end of 6 month. Functional outcome scores were improved significantly from their baseline values in PRP group while in placebo group the mean functional score were deteriorated at 6 months follow up. There was no improvement seen in functional status with normal saline injection. In PRP group the mean heal pad thickness was reduced significantly at 6 months follow up while in placebo group was not changed significantly at 6 months follow up. Correlation between radiological parameters and VAS was found to be positive while it was found negative with other functional outcome scores like AOFAS.Conclusions: Platelet-rich plasma (PRP), which is a natural concentrate of autologous growth factors,plays a role in the regeneration process in treatment of (PF).
