PURPOSE: To evaluate the clinical results of an arthroscopy-assisted latissimus dorsi tendon transfer (aLD) for irreparable posterosuperior cuff tears as a primary surgery. The secondary aim of this study was to quantify the learning curve using the log-linear model. We hypothesized that aLD significantly improved shoulder function and that there was consistent reduction of the operative time in support of a learning-curve effect. METHODS: After the arthroscopic partial repair was completed, the latissimus dorsi tendon was harvested via axillary mini-open incision and fixed with a knotless anchor arthroscopically...

PURPOSE: To investigate the 2-year postoperative clinical and subjective outcomes after arthroscopic rotator cuff repair (ARCR) with xenologous porcine dermal patch augmentation compared with ARCR alone. METHODS: Patients aged 60 years or older with a complete supraspinatus (SSP) tendon tear underwent primary ARCR with a transosseous-equivalent technique. By use of a matched-pair comparative trial design, a consecutive series of 20 patients receiving additional xenologous porcine dermal patch augmentation (patch group) was matched by tear location with 20 patients who received ARCR only (control group)...

BACKGROUND: We previously studied the intramuscular innervation of 150 upper limb muscles and demonstrated that certain patterns of intramuscular innervation allowed muscles to be split into compartments with independent function. This study aims to determine the location, extra-muscular course, and number of motor nerve branches of upper limb peripheral nerves. We want to combine this information with our previous work to create a blueprint of upper limb neuromuscular anatomy that would be useful in reconstructive surgery...

Claw finger is sequelae of fingers without intrinsic function. Claw toe deformity is common after toe transfers as simultaneous intrinsic reconstruction has yet to be reported in the literature. We present our experience of simultaneous tendon transfers during the second toe transplantation. Seven 2nd toe transfers were performed in 5 metacarpal-like and metacarpal hands. The Stiles-Bunnell tendon transfer was incorporated into toe transfers. Toe lumbrical tendons were repaired to the Flexor Digitorum Sublimis of the same recipient digit...

Infected nonunion of a forearm fracture complicated by a considerable skin-muscle defect poses a great challenge to orthopaedic surgeons. The treatment strategy comprises eradication of the infection, ensuring bony union and soft tissue coverage along with functional restoration. We report a case of a 23-year-old man with an open Gustilo-Anderson IIIb fracture complicated by infected nonunion after internal fixation. After thorough surgical debridement, a considerable soft tissue defect, extensor muscle loss, and posterior interosseous nerve laceration had to be addressed...

BACKGROUND: Symptomatic non-union of medial humeral epicondylar fractures is a limited entity. Some studies recommend surgical excision of the fragment, but the results are controversial. The purpose of this study is to evaluate the outcome of open reduction and internal fixation of a medial epicondyle non-union fragment. MATERIALS AND METHODS: A retrospective study was conducted in all the patients, who were operated in our hospital between the year 2010 and 2015 for symptomatic medial humeral epicondyle non-union...

In early stages of tendon disease, mechanical properties may become altered prior to changes in morphological anatomy. Ultrashort echo time (UTE) magnetic resonance imaging (MRI) can be used to directly detect signal from tissues with very short T2 values, including unique viscoelastic tissues such as tendons. The purpose of this study was to use UTE sequences to measure T2(∗), T1 and magnetization transfer ratio (MTR) variations of tendon samples under static tensile loads. Six human peroneal tendons were imaged before and under static loading using UTE sequences on a clinical 3T MRI scanner...

Reconstruction of extensive traumatic bone and soft tissue deficits in the hand often presents a significant challenge. We present a case of a gunshot wound managed with a resourceful "vascularized spare parts" reconstruction in which a single compromised digit provided two separate vascularized tissue transfers. A rarely reported pedicled phalanx restored osseous stability, a digital fillet flap achieved soft tissue coverage, and the flexor tendons reanimated the hand. An excellent functional and cosmetic result was obtained and the patient was able to return to manual labor within six months of injury...

BACKGROUND: Various techniques of opponensplasty have been developed with the aim of restoring the thumb function. The modified Camitz opponensplasty is a simple technique done together with an open carpal tunnel release. It restores thumb palmar abduction soon after the procedure, during such time that the abductor pollicis brevis (APB) is still recovering. The aim of this study was to assess the recovery and level of activity of the abductor pollicis brevis and palmaris longus (PL) muscles during thumb opposition and abduction after performing the modified Camitz opponensplasty...

BACKGROUND: Spastic thumb deformity in cerebral palsy significantly impedes hand function. Flexion-adduction forces across the first ray is the result from imbalance between intrinsic and extrinsic muscles. Multiples surgeries have been devised for the treatment of this condition such as contracture release and by tendon transfers for balancing the muscles forces. We report the results of a less demanding surgical technique, intended to avoid hyperextension of the metacarpophalangeal joint previously described in other series...

AIMS: After the initial correction of congenital talipes equinovarus (CTEV) using the Ponseti method, a subsequent dynamic deformity is often managed by transfer of the tendon of tibialis anterior (TATT) to the lateral cuneiform. Many surgeons believe the lateral cuneiform should be ossified before surgery is undertaken. This study quantifies the ossification process of the lateral cuneiform in children with CTEV between one and three years of age. PATIENTS AND METHODS: The length, width and height of the lateral cuneiform were measured in 43 consecutive patients with unilateral CTEV who had been treated using the Ponseti method...

BACKGROUND: In adults with lower trunk brachial plexus injury, proximal nerve surgery for restoration of prehension demonstrates poor outcomes secondary to long distances required for nerve regeneration and time-dependent degradation of motor endplates. Options for reconstruction are limited to distal tendon or nerve transfers and free-functioning muscle transfers. In this article, the authors describe the long-term outcomes of brachialis muscle-to-flexor digitorum profundus transfer to restore prehension in patients with traumatic lower trunk brachial plexus injuries...

INTRODUCTION: In anterior transfer of the tibialis posterior tendon, the tendon was harvested using two incisions, the first at its attachment point on the navicular bone and second on the medial side of the leg above the medial malleolus. To provide the maximum tendon length, the second incision needs to be as proximal as possible but injury to the muscle origin must be avoided. The purpose of this study is to establish the location of the second incision that yields the greatest tendon length...

Background  Minimally invasive plate osteosynthesis (MIPO) has been used in wrist surgery for several years. The purpose of this retrospective study was to compare clinical and radiologic outcomes of MIPO technique with those of a conventional approach in the treatment of metadiaphyseal distal radius fracture by long volar plating. Materials and Methods  Our series consisted of 32 fractures in 31 patients, mean age 63.9 years, including 16 men and 15 women. MIPO technique was used in 15 wrists (group 1) and conventional approach (> 60 mm of skin incision) in 17 wrists (group 2)...

BACKGROUND: Hospital transfer decisions regarding pyogenic flexor tenosynovitis (PFT) are made difficult by emergency department presentations similar to other finger infections, with pain, redness, and functional limitation. Our objectives were to: (1) determine diagnostic sensitivity and specificity of Kanavel signs; and (2) identify existing factors most predictive of PFT during initial presentation. METHODS: Adult patients who underwent surgical consultation for concern of PFT over a 5-year period were identified retrospectively...

OBJECTIVE: To demonstrate the in situ repair technique of high-degree partial-thickness articular surface lesions of the supraspinatus tendon (SS). The procedure consists of the arthroscopic surgical repair of these lesions, without the need to complete the lesion, as occurs in traditional classical technique. A small incision is made in the longitudinal direction of the intact bursal fibers and where bone fixation anchors are introduced, which makes the procedure easier. These anchors are transferred to the tendon and thus enable the repair of the lesion...
