Ice hockey is a fast-paced contact sport with a high rate of injury. While many of the injuries are acute and related to high skating speeds, frequent collisions, and sharp skates, the clinician must also be aware of the chronic injuries that commonly arise from playing this sport. The "Bauer bump" is one such chronic injury, which is the onset of Haglund syndrome in ice hockey players occurring in the context of wearing ice hockey skates. With this condition, players notice a bony enlargement of their posterosuperior calcaneus with or without the accompanying symptoms of retrocalcaneal bursitis and insertional Achilles tendinopathy. It is important for clinicians to understand the nature of Haglund syndrome in hockey players so that it can be appropriately diagnosed, managed, and ultimately, prevented.

Return-to-Competition Criteria After Ulnar Collateral Ligament Reconstruction: A Systematic Review and Meta-analysis.

Am J Sports Med 2022 03 28;50(4):1157-1165. Epub 2021 Jun 28.

Department of Orthopedic Surgery, Columbia University Irving Medical Center, New York, New York, USA.

Background: Injury to the ulnar collateral ligament of the elbow is common among overhead throwing athletes and can result in significant functional limitations. While surgical reconstruction offers high rates of return to competition, there are no validated or universally accepted guidelines for determining when an athlete can safely resume play.

Purpose: To assess the existing scientific literature for return-to-competition criteria utilized after ulnar collateral ligament reconstruction.

Study Design: Systematic review and meta-analysis; Level of evidence, 4.

Methods: The PubMed database was searched for clinical investigations of ulnar collateral ligament reconstruction in overhead throwing athletes published between January 2000 and June 2020. Only studies that had a minimum follow-up of 1 year and included at least 1 specific return-to-competition criterion were considered.

Results: A total of 15 studies were included in the final analysis, encompassing 1156 patients with an average age of 20.7 years (SD, 2.0 years). Baseball players composed 96.3% of patients for whom sport was specified, and 92.4% of baseball players were pitchers. The most common return-to-competition criterion, identified in 87% of studies, was completion of a return-to-throwing program, which started on average 16.7 weeks (range, 12-18 weeks) after surgery. A return-to-mound program was utilized in 53% of studies, starting on average 7.4 months (range, 6-9 months) postoperatively. Minimum time from surgery was used in 73% studies, with players waiting 7 to 12 months (mean, 9.7; SD, 1.4 months) after surgery before return-to-competition consideration. The overall rate of return to competition at the preinjury level or higher was 85.7% (SD, 8.5%) at an average of 12.2 months (SD, 0.6 months).

Conclusion: In general, we observed a paucity of literature describing the return-to-competition process after ulnar collateral ligament reconstruction in overhead throwing athletes. Only 3 explicit return-to-competition criteria were identified across all studies: completion of a return-to-throwing program, completion of a return-to-mound program for pitchers, and minimum time from surgery. Increased transparency regarding postoperative rehabilitation protocols and further research are necessary to identify and validate sport-specific return-to-competition criteria, which will ultimately help athletes return to play in a safe and timely fashion after ulnar collateral ligament reconstruction.

Outcomes of press-fit uncemented versus cemented hip arthroplasty in the oncologic patient.

J Orthop 2020 Nov-Dec;22:198-202. Epub 2020 May 4.

Department of Orthopaedic Surgery, North Shore-Long Island Jewish Medical Center, Northwell Health, 270-05 76th Avenue, New Hyde Park, NY, 11040, USA.

Background And Objectives: Cemented hip arthroplasty is considered the standard of care for treating both osteoporotic femoral neck fractures and pathologic disease of the proximal femur due to the ability to achieve strong fixation in poor quality bone. There is minimal literature evaluating uncemented arthroplasty for pathologic disease of the proximal femur. This objective of this study is to compare outcomes of patients undergoing cemented and uncemented arthroplasty of the proximal femur for an oncologic indication.

Methods: Patients who underwent hip arthroplasty procedures in one health system for an oncologic indication were identified. Demographics, cancer history, operative history, and complications were collected retrospectively. Harris Hip Scores (HHS) and Musculoskeletal Tumor Society Scores (MSTS) were prospectively collected via telephone.

Results: 41 patients met criteria for review. 18 underwent cemented and 23 underwent uncemented arthroplasty. There were no significant differences in age, demographics, complications, 30-day mortality, intraoperative blood loss, transfusion requirements, average HHS, or average MSTS.

Conclusion: No significant differences were found for patients undergoing hip arthroplasty for an oncologic indication regardless of whether or not the femoral component was cemented. Our results suggest that cemented and uncemented techniques are both safe and effective methods to be used at the oncologic surgeon's discretion.
