The fate of femoral head autograft in acetabular reconstruction in dysplastic hips at midterm.

CONCLUSION: In patients with osteoarthritis secondary to developmental hip dysplasia, the use of femoral head autografts to eliminate acetabular coverage deficiency during THA achieves acceptable midterm postoperative radiological outcomes. Increased acetabular bone stock may be beneficial in possible future revision surgeries. PMID: 32996378 [PubMed - in process]

Abstract OBJECTIVE: Restoration of anatomy of the joint surface of the tibial plateau in posttraumatic deformity. INDICATIONS: Malunions of the tibial plateau with significant intra-articular depression and/or steps. CONTRAINDICATIONS: Local or systemic infection, critical soft tissues in the area of planned incisions; advanced osteoarthritis of the knee; loss of meniscus in the involved compartment; motoric or neurophysiological impairment hindering normal knee function. SURGICAL TECHNIQUE: Malunion after posteromedial split fracture: posterior approach in prone position, osteotomy of the former fr...

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]

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 r...

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.
