Needle Curette Technique for Hand Surgery.

Curettage of lesions in the hand often requires fine instruments of varying angles for a thorough debridement. This can be seen with debridement of enchondromas of the phalanges when minimizing the size of the cortical window is desired. In this technical note, the authors describe the modification of an 18-G needle so that it may be used as a small curette when standard small curettes are not available or optimal.

Fibrin glue augmentation for flexor tendon repair increases friction compared with epitendinous suture.

PURPOSE: To compare the gliding resistance, repair gapping, and ultimate strength of a common suture construct with a modified construct with fibrin glue augmentation. METHODS: Twelve human cadaveric flexor digitorum profundus tendons were transected and repaired with a 4-strand core suture. Specimens were divided into 2 groups and augmented with epitendinous suture (n = 6) or fibrin glue (n = 6). We compared gliding resistance, 2-mm gapping, and ultimate strength of the repaired tendon between groups. RESULTS: The linear stiffness, force to produce a 2-mm gap, and ultimate failure were similar in both repair methods. However, the 4-strand suture repair with fibrin glue augmentation displayed significantly higher gliding resistance compared with the 4-strand suture with a running epitendinous suture. CONCLUSIONS: The significantly increased gliding resistance associated with fibrin glue raises questions regarding the use of this material for flexor tendon repair augmentation. CLINICAL RELEVANCE: In a human cadaveric study, fibrin glue augmentation to zone II flexor tendon repairs significantly increased friction in the tendon sheath compared with an epitendinous suture.

Tendon disorders of the foot and ankle, part 3: the posterior tibial tendon.

This article provides a review of posterior tibial tendon pathology and the authors' preferred management. The tibialis posterior musculotendinous unit is the most powerful inverter of the foot and an important dynamic stabilizer of the arch. In the stance phase of the gait cycle, it serves as an initiator of both ankle plantar flexion and subtalar inversion. This creates a rigid midfoot by stabilizing the transverse tarsal joint, and allows for increased power generation by the gastrocsoleus complex through toe-off. Injuries to the posterior tibialis tendon include traumatic laceration and dislocation, as well as tenosynovitis and tendinopathy, which can lead to attenuation and rupture. If these injuries are not addressed, significant clinical deformity and disability can result.

Tendon disorders of the foot and ankle, part 2: achilles tendon disorders.

Disorders of the Achilles tendon include both acute and chronic ruptures as well as a spectrum of chronic overuse injuries involving inflammatory and degenerative changes within the tendon and surrounding tissues. These injuries are relatively common in athletes as well as among the general population. There is no consensus on the optimal treatment of Achilles tendon disorders. The goals of this review are to develop a current understanding of the anatomy and diagnostic evaluation of the Achilles tendon, and to present current treatment options and the authors' preferred surgical techniques for operative management of Achilles tendon disorders.

Tendon disorders of the foot and ankle, part 1: peroneal tendon disorders.

Pathologic abnormality of the peroneal tendons is an uncommon but underappreciated source of lateral hindfoot pain and dysfunction that can be difficult to distinguish from lateral ankle ligament injuries. When left untreated, peroneal tendon disorders can lead to persistent lateral ankle pain and substantial functional problems. Unfortunately, the treatment recommendations for these disorders are primarily based on case series and expert opinion. The goals of this review are to develop a current understanding of the anatomy and diagnostic evaluation of the peroneal tendons, and to present current treatment options and the authors' preferred surgical techniques for operative management of peroneal tendon lesions.

The lumbar spine and low back pain in golf: a literature review of swing biomechanics and injury prevention.

BACKGROUND CONTEXT: The golf swing imparts significant stress on the lumbar spine. Not surprisingly, low back pain (LBP) is one of the most common musculoskeletal complaints among golfers. PURPOSE: This article provides a review of lumbar spine forces during the golf swing and other research available on swing biomechanics and muscle activity during trunk rotation. STUDY DESIGN: The role of "modern" and "classic" swing styles in golf-associated LBP, as well as LBP causation theories, treatment, and prevention strategies, are reviewed. METHODS: A PubMed literature search was performed using various permutations of the following keywords: lumbar, spine, low, back, therapy, pain, prevention, injuries, golf, swing, trunk, rotation, and biomechanics. Articles were screened and selected for relevance to injuries in golf, swing mechanics, and biomechanics of the trunk and lumbar spine. Articles addressing treatment of LBP with discussions on trunk rotation or golf were also selected. Primary references were included from the initial selection of articles where appropriate. General web searches were performed to identify articles for background information on the sport of golf and postsurgical return to play. RESULTS: Prospective, randomized studies have shown that focus on the transversus abdominus (TA) and multifidi (MF) muscles is a necessary part of physical therapy for LBP. Some studies also suggest that the coaching of a "classic" golf swing and increasing trunk flexibility may provide additional benefit. CONCLUSIONS: There is a notable lack of studies separating the effects of swing modification from physical rehabilitation, and controlled trials are necessary to identify the true effectiveness of specific swing modifications for reducing LBP in golf. Although the establishment of a commonly used regimen to address all golf-associated LBP would be ideal, it may be more practical to apply basic principles mentioned in this article to the tailoring of a unique regimen for the patient. Guidelines for returning to golf after spine surgery are also discussed.

Supine positioning for surgical repair of the Achilles tendon.

In this article, we describe supine positioning for Achilles tendon surgery. We find this to be a safer and more efficient method than either prone or lateral positioning. It allows easier access for airway monitoring, it does not compromise access to the surgical site, and it requires less setup time for both anesthesia and surgical positioning, thereby potentially saving time in the operating room.
