Radiological results of Shelf acetabuloplasty in adolescent hip dysplasia with aspherical femoral head: how to get an ideal placement of the Shelf graft

Shelf acetabuloplasty continues to be effective in the prevention or delay of osteoarthritis in adolescent dysplastic hips. We aimed to evaluate the efficacy and to determine the correct level of the bone graft objectively. We retrospectively analyzed 16 hips underwent Shelf acetabuloplasty originated by Spitzy. The mean age at surgery was 15.3 years old with the mean caput index at 39.7%. The average follow-up was 11 years. The radiological evaluation was based on acetabular-head index (AHI) at preoperative and latest radiographs, acetabular-Shelf distance (ASD) and Shelf-head ratio at immediate postoperative and latest radiographs. The cutoff value for the ideal ASD was determined by receiver operating characteristic (ROC) and the Pearson correlation test used in statistical analysis to assess the relationship between ASD and Shelf graft resorption. Clinical evaluation was performed using Harris Hip Score (HHS) at the latest follow-up. The AHI was improved in all cases, from mean 56.9 to 91.0% (P

Abstract BACKGROUND: The Bernese periacetabular osteotomy (PAO) is one of the most-used surgical techniques to treat symptomatic acetabular dysplasia. Although good functional and radiographic short-term and long-term outcomes have been reported, several complications after PAO have been described. One complication that may compromise clinical results is nonunion of an osteotomy. However, the exact prevalence and risk factors associated with nonunion are poorly elucidated. QUESTIONS/PURPOSES: (1) What proportion of patients have complete bony healing versus nonunion during the first year after PAO? (2) What i...

Conclusion: Contrary to previous reports, low complication and revision rates were observed with cementless components and routine use of allograft material. The challenging nature of such cases warrants use of an experienced arthroplasty treatment team. PMID: 32356947 [PubMed - as supplied by publisher]

Authors: Sanchez-Sotelo J Abstract Understanding the location and magnitude of glenoid bone loss is extremely important at the time of both primary and revision shoulder arthroplasty. Specific patterns of glenoid bone loss have been described for primary glenohumeral osteoarthritis, cuff tear arthropathy, inflammatory arthritis, and failed shoulder arthroplasty. Although radiographs are useful in planning arthroplasty procedures, CT has become the imaging modality of choice to evaluate and classify bone loss before shoulder arthroplasty. Two-dimensional images may be used to measure various angles and calculate are...

This article investigates the clinical, functional, and radiographic outcomes in anterior cruciate ligament (ACL) reconstruction patients over 7 years to determine the effects of initial graft tension on outcomes when using patellar tendon (bone–tendon–bone [BTB]) and hamstring tendon (HS) autografts. Ninety patients, reconstructed with BTB or HS, were randomized using two initial graft tension protocols: (1) normal anteroposterior (AP) laxity (“low-tension”; n = 46) and (2) AP laxity overconstrained by 2 mm (“high-tension”; n = 44). Seventy-two patient...

ConclusionBimeniscal replacement by an allograft and/or substitute provides good short-term functional and anatomical outcomes. Nevertheless, this procedure is warranted only in highly selected patients.Level of evidenceIV, retrospective study.

ConclusionsAnatomic ACL reconstruction could restore not only the normal anterior knee laxity, but also the normal tibiofemoral relationship even under an anterior tibial load.

ConclusionsUsing non-irradiated allografts for one-stage reconstructions of all the injured ligaments in MLKIs is effective and safe. Anteroposterior stability was difficult to restore, but patients returned to their daily activities and sometimes to their sports activity at the same preinjury level.Level of evidenceLevel IV, case series.

J Knee Surg DOI: 10.1055/s-0039-1695040Patellar bone–tendon–bone (pBTB) autografts are often considered the “gold standard” for complete anterior cruciate ligament (ACL) reconstruction and are also associated with significant complications and early-onset knee osteoarthritis (OA). A novel quadriceps tendon allograft with synthetic augmentation, or “internal brace” (QTIB), has been reported to have potential advantages for ACL reconstruction based on animal model data. In this preclinical canine comparison study, we hypothesized that QTIB allograft compared with pBTB autograft would provi...

ConclusionsLarge variations of PFJ OA after ACL injury are associated with different follow-up period and surgical techniques. ACL reconstructed population with bone-patellar tendon-bone graft, single-bundle reconstruction, and delayed operation time has a high prevalence of PFJ OA.
