ACL graft compression: a method to allow reduced tunnel sizes in ACL reconstruction

Breck R. Lord, Henry B. Colaco, Chinmay M. Gupte, Adrian J. Wilson, more

Knee Surgery, Sports Traumatology, Arthroscopy > 2018 > 26 > 8 > 2430-2437

Purpose A common problem during ACL reconstruction is asymmetry of proximal–distal graft diameter leading to tunnel upsizing and graft–tunnel mismatch. Compression downsizing provides a graft of uniform size, allowing easy passage into a smaller tunnel. The purpose of this study was to quantify the graft compression technique and its effects on graft biomechanics and stability. It was hypothesised...

Biomechanical properties of bovine tendon xenografts treated with a modern processing method

Henry B. Colaço, Breck R. Lord, Diane L. Back, Andrew J. Davies, more

Journal of Biomechanics > 2017 > 53 > C > 144-147

Xenograft tendons have been used in few human studies, with variable results. With the advent of novel tissue processing techniques, which may mitigate against an immune-mediated rejection response without adversely affecting mechanical properties, there may now be a clinical role for xenograft tendons, particularly in knee ligament reconstruction. We hypothesize that ‘BioCleanse®’ processed bovine...

Construct Validity, Assessment of the Learning Curve, and Experience of Using a Low-Cost Arthroscopic Surgical Simulator

Henry B. Colaco, Katie Hughes, Eyiyemi Pearse, Magnus Arnander, more

Journal of Surgical Education > 2017 > 74 > 1 > 47-54

We have developed a low-cost, portable shoulder simulator designed to train basic arthroscopic skills. This study aimed to establish the construct validity of the simulator by determining which parameters discriminated between experience levels and to assess the experience of using the simulator.Participants were given an introductory presentation and an untimed practice run of a 6-step triangulation...

Arthroscopic Conjoint Tendon Transfer: A Technique for Revision Anterior Shoulder Stabilization

Duncan Tennent, Henry B. Colaço, Magnus Arnander, Eyiyemi Pearse

Arthroscopy Techniques > 2016 > 5 > 1 > e201-e205

Revision anterior stabilization of the shoulder presents a challenge to the surgeon and carries a higher risk of recurrent dislocation than primary repair. The Latarjet procedure may be more reliable than revision soft-tissue repair but may not be indicated in patients without significant glenoid bone loss. We describe an arthroscopic technique of conjoint tendon transfer using a combination of suspensory...

(i) Surgical approaches for shoulder arthroplasty

Henry B. Colaço, Magnus Arnander, Eyiyemi O. Pearse, T. Duncan Tennentf

Orthopaedics and Trauma > 2015 > 29 > 5 > 281-286

Shoulder arthroplasty is most commonly performed via a deltopectoral (DP) or anterosuperior (AS) approach, and several modifications of each have been described. Both approaches can be used for resurfacing, stemless and stemmed hemiarthroplasty, anatomic total shoulder arthroplasty (TSA), and reverse shoulder arthroplasty (RSA). This article aims to give a practical guide to performing both approaches,...

Post-traumatic osteonecrosis of the proximal humerus

Shelain Patel, Henry B. Colaco, Michael E. Elvey, Marcus H. Lee

Injury > 2015 > 46 > 10 > 1878-1884

Post-traumatic osteonecrosis of the proximal humerus represents a challenging problem to the surgeon. It is commonly seen following multi-fragmentary fractures of the proximal humerus which may affect the long-term functional recovery after such injuries. This review summarises the current evidence on risk factors, reasons why estimating its epidemiology is difficult, the vascular supply of the humeral...

(iv) Xenograft in orthopaedics

Henry B. Colaço, Zameer Shah, Diane Back, Andrew Davies, more

Orthopaedics and Trauma > 2015 > 29 > 4 > 253-260

The use of xenograft tissue in orthopaedics has an interesting history and has yielded mixed clinical results, although the potential future application of xenografts processing with novel techniques is promising. This review aims to cover the basics of tissue rejection, zoonoses and processing methods, as well as the laboratory and clinical evidence for the use of bone and soft tissue xenografts.

The accuracy of primary care teams in diagnosing disorders of the shoulder

Shelain Patel, Fahad S Hossain, Henry B Colaco, Moataz El‐Husseiny, more

Journal of Evaluation in Clinical Practice > 17 > 1 > 118 - 122

Objective The aim of this retrospective, observational study was to determine the accuracy of diagnoses given by a multitude of primary care services to patients referred to an orthopaedic upper limb surgeon with a focus towards shoulder pathology. Methods Records of all patients referred to a single upper limb surgeon over a 1‐year period were reviewed. The diagnosis in the primary care setting...

Impingement of a fibroma of the extensor tendon sheath on the extensor retinaculum

Shelain Patel, Henry B. Colaco, Emma J. Taylor

Journal of Hand and Microsurgery > 2010 > 2 > 1 > 31-32

Deep lacerations to the forearm can cause impaired movement of the digits. This report describes the presentation and management of a self-harmer who presented with loss of motion of her ring finger. Surgical exploration unexpectedly demonstrated the cause to be a fibroma of the tendon sheath impinging on the extensor retinaculum. Full recovery was demonstrated at sixmonth review following removal...
