Amanda Lans, Stein J Janssen, David Ring
PURPOSE: We sought to determine and quantify which subspecialties of orthopedic surgeons are operating off hours in an urban, quaternary-care, level 1 trauma center. MATERIALS AND METHODS: We used our clinical registry to identify 43,211 orthopedic surgeries performed between January 2008 and December 2011. Our outcome measures were the number and proportion of off-hour surgeries performed as well as the number and proportion of off-hours per subspecialty. The denominators were the total number of surgeries and the total number of surgical hours worked per subspecialty...

PURPOSE: Hospital volume-outcome association has been examined for many high-risk surgical procedures. Little is known about this association for thumb replantation, a complex but essential surgical procedure to restore hand function. We aimed to determine patient and hospital characteristics that are associated with increased probability of replanted thumb survival and to examine volume-outcome association among hospitals that performed thumb replantation. METHODS: We used data from 2008 to 2012 from the National Trauma Data Bank...

Amputation by crush injuries generally represents a contraindication for replantation, and especially when the lesion is caused by the summation of multiple concomitant traumatic mechanisms. We present the case of a 22 year- old female who arrived in our service with a crush/torsion amputation of all long fingers at the metacarpo-phalangeal level of the right hand. After the unsuccessful attempt of replantation, the functional reconstruction of the hand was achieved by using a double free flap transfer: anterolateral thigh perforator flap (ALT) and digital block transfer of second and third toes...

Secondary surgical procedures can improve the function of revascularised and replanted digits. We describe the case of a patient who underwent multidigit revascularisation and replantation following a saw injury at flexor tendon Zone II. To achieve maximal functional improvement after finger revascularisation, we performed secondary surgical procedures in an order that was determined by following a reconstructive decision procedure that covered late revascularisation, nerve reconstruction, pedicled vascularised joint transfer, staged flexor tendon reconstruction and skin revision...

The thumb plays an integral role in hand function. Traumatic amputation results in significant morbidity. With loss of the thumb, up to a 40% reduction in hand function may result. Thumb replantation must be attempted when possible. The goals of thumb reconstruction are to replicate normal function as closely as possible, minimize donor site morbidity, and expedite recovery. In the setting of a mutilated hand, the status of the remaining digits must be carefully assessed. Toe transfers, osteoplastic thumb reconstruction, and pollicization are commonly used...

The thumb is the most important part of the hand. If thumb is amputated, all efforts should be made to replant it to preserve hand functions. Good functional outcome can be obtained with successful thumb replantation than with other reconstructive surgery. We present a case of thumb amputation of a 44 -year-old male with severe damage to the soft tissues and bony structures of the radial part of the hand. We performed the replantation anastomosing the superficial palmar branch of the radial artery as donor artery as the proximal part of thumb digital arteries were severely damaged due to crush injury and got favorable result...

INTRODUCTION: Air transportation to tertiary care centers of patients with upper extremity amputations has been utilized in hopes of reducing the time to potential replantation; however, this mode of transportation is expensive and not all patients will undergo replantation. The purpose of this study is to review the appropriateness and cost of air transportation in upper extremity amputations. MATERIALS AND METHODS: Consecutive patients transported by aircraft with upper extremity amputations in a 7-year period at a level-1 trauma center were retrospectively reviewed...

Toe-to-hand transfer is the last option for definitive reconstruction of the hand when digits have been lost as a result of traumatic amputations, congenital anomalies, or tumor ablation. Immediate toe-to-hand transfer for the treatment of acute hand injuries is defined as an emergency operation performed when replantation is impossible or failed. The aim of this article is to propose the indications, advantages and disadvantages of immediate toe to hand transfer as well as to compare the overall results with elective cases...

Background There are a few previous studies of the vascular anatomy of the fingertips. The aim of this study was to evaluate this anatomy and the distribution of fingertip arteries. Patients and Methods A total of 31 cadaveric hands were used for evaluation of the vascular pattern of the fingertips on X-ray images obtained using a radiopaque material. We analyze the anatomy of the fingertip arteries, and classified it into three types in Tamai zone I. If only one dominant artery branched off from the distal transverse palmar arch, it was classified as type I...

BACKGROUND: The fingertip is the most frequently injured and amputated segment of the hand. There are controversies about defining clear indications for microsurgical replantation. Many classification systems have been proposed to solve this problem. No previous study has simultaneously correlated different classification systems with replant survival rate. The aim of the study is to compare the outcomes of fingertip replantations according to Tamai and Yamano classifications. MATERIALS AND METHODS: 34 consecutive patients who underwent fingertip replantation between 2007 and 2014 were retrospectively reviewed with respect to the Tamai and Yamano classifications...

Microvascular surgery is becoming a prevalent surgical practice. Replantation, hand reconstruction, orthopedic, and free tissue transfer procedures all rely on microvascular surgery for the repair of venous and arterial defects at the millimeter and submillimeter levels. Often, a vascular graft is required for the procedure as a means to bridge the gap between native arteries. While autologous vessels are desired for their bioactivity and non-thrombogenicity, the tedious harvest process, lack of availability, and caliber or mechanical mismatch contribute to graft failure...

Replantation is a prime indication for distal digital amputation, as it helps restore hand aesthetics and functions; however, venous anastomosis is often not feasible. Previous studies used systemic anticoagulation in distal digital artery only anastomosis replantation surgery to improve replantation success rate, however, which yielded limited level of clinical evidence. This study aimed to compare controlled continuous heparinization (CCH) and intermittent bolus heparinization (IBH) for surgical outcome and clinical variables after single distal digital artery only anastomosis replantation surgery...

Surgical treatment of complete cutaneous ring finger avulsion is a challenge in hand surgery. When replantation of the avulsed fragment is not technically feasible, the surgeon must consider reconstruction of soft tissue. Many surgical techniques have been described. We report a case of complete avulsion of the cutaneous sheath and nail of the fourth finger with preservation of mobility and collateral nerves. The reconstruction of soft tissue was performed by a Colson flap-graft. This simple and reliable technique of reconstruction allowed to obtain a functional and sensitive finger with a satisfactory cosmetic result...
