Isolated closed rupture of the bony insertion of the flexor digitorum superficialis tendon: an unusual case.

We describe a case of isolated rupture of the flexor digitorum superficialis tendon due to middle phalangeal cortical bone avulsion with a 4-month delay in treatment. X-ray examination revealed an area of calcification in the flexor tendon sheath proximal to the proximal interphalangeal joint. Excision of the bone fragment and surrounding scar tissue corrected nearly all the 60 degrees extension lag at the proximal interphalangeal joint, which was the most notable functional loss.

Advances in reconstruction of digital joints.

The recent development of dynamic traction provides several advantages for the treatment of intra-articular fractures of the hand: Ligamentotaxis reduces fracture fragments and realigns joint surfaces, Contracture of joint ligament and periarticular structures is prevented, Collapse of fracture fragments is prevented, Cartilage healing and regeneration are enhanced, Joint mobility is retained, Extensive surgery may be avoided, As Leonardo da Vinci stated, "To understand motion is to understand nature."

Results of zone II flexor tendon lacerations in civilians treated by the Washington regimen.

Thirty-three civilian patients with 44 digits that had zone II lacerations of the flexor tendons were treated by the Washington regimen. No cases with phalangeal fractures, joint injuries, or skin loss were included. The patients attended therapy five times per week for 2 weeks, and then three times per week for 4 more weeks. Only the 18 patients (55% of the original treatment cohort; among them, there was a total of 25 injured digits) who completed the 6 weeks of treatment and returned for follow-up evaluation at either 3 or 6 months were included in the results. Using the Strickland-Glogovac evaluation method, results were excellent in 36% of cases, good in 12%, fair in 20%, and poor in 32%. These results are in marked contrast to those previously reported, and surgeons in the nonmilitary setting should consider these more realistic expectations when selecting a method of treatment.

Adhesive capsulitis of the wrist.

The authors report the arthrographic features of adhesive capsulitis of the wrist in a patient who had undergone prolonged wrist immobilization. The diagnosis was made on the basis of pain and early filling of the lymphatic vessels during the injection of contrast material, as well as small joint capacity.

Classification of fractures and dislocations of the proximal interphalangeal joint.

Detailed categorization of fractures and fracture-dislocations of the proximal interphalangeal joint should be done for all patients with these injuries. Fractures of the proximal portion of the middle phalanx and fractures of the condyles of the proximal phalanx vary greatly in their presentation, severity, prognosis, and treatment. Fractures of the condyles can be categorized simply by noting whether they are unicondylar or bicondylar, and with or without displacement. For the middle phalanx, I propose the grading system listed in Table 1. Universal acceptance and application of this classification system will advance our understanding and treatment of these difficult fractures.

The dynamic traction method. Combining movement and traction for intra-articular fractures of the phalanges.

Dynamic traction is a new method of treatment of intra-articular fractures in the hand, combining the old idea of traction and the recent one of movement. Traction reduces fracture fragments through ligamentotaxis, and helps prevent joint ligament and periarticular contracture. Motion encourages cartilage regeneration and helps maintain mobility. Both early and long-term results have been excellent. The historical development of dynamic traction is detailed, and a summary given of the physiologic basis for the method's success.

Carpal tunnel syndrome: the new 'industrial epidemic'.

1. Symptoms of carpal tunnel syndrome (CTS) include numbness, tingling, and decreased sensation in the fingers. 2. The main occupational causes of CTS include repetitive wrist flexion and extension, strong gripping with ulnar deviation, impact forces on the palm, and vibratory forces. 3. Conservative treatment includes a metal-reinforced splint that prevents flexion and extension of the wrist. Surgical treatment may be needed for severe symptoms. 4. Prevention of CTS requires early diagnosis, job reassignment, and tool redesign.

Dynamic traction and early passive movement for fractures of the proximal interphalangeal joint.

Unstable intra-articular fractures that involve the proximal and middle phalanges often lead to joint stiffness and loss of function. Ten patients with comminuted intra-articular fractures of the proximal interphalangeal (PIP) joint were treated by dynamic traction splinting and early mobilizations. Distal traction, with a force of 300 g, was provided by a rubber band connecting a transosseous wire to a movable component on an arcuate splint made of thermoplastic material. Intermittent passive movement was carried out on a timed schedule. Follow-up at 16 months (5 months to 51/2 years) showed a pain-free final range of motion (ROM) of 87 degrees (5 degrees to 92 degrees), with preservation of articular symmetry and space. this is the first report of treatment of intraarticular fractures in the hand by a combination of dynamic traction and passive movement.

Hypothenar skin grafts for fingertip reconstruction.

Full-thickness skin grafts from the hypothenar area were used to reconstruct 25 digits in a group of 20 patients. The results were evaluated objectively and subjectively at an average of 9.5 months after operation for sensibility, durability, and appearance. Eighty-six percent of the patients had two-point discrimination of 10 mm or less, with one half of them having two-point discrimination of less than 6 mm. All patients had good protective coverage and no ulcer formation. All patients could differentiate between coarse and smooth texture, although only one third had texture discrimination equal to that of normal digits. None of the patients complained of hypersensitivity. The donor site was cosmetically acceptable in all cases. The use of hypothenar full-thickness grafts provides an acceptable method for fingertip reconstruction, particularly in instances of palmar and lateral pulp loss in which there is insufficient tissue available for local advancement.

The "rule of tens" prediction of functional results. An aid for selection for replantation.

A system incorporating digital length is offered which, by enabling the surgeon to reasonably predict the degree of function expected after digital replantation of amputation, serves as an aid in patient selection. Length analysis was made by dividing each digit into 10 anatomical zones, numbered from 1 (tip) to 10 (through the metacarpal). A method of scoring was devised based on the digit involved as well as its length, the nature of the injury, the condition of the part, and the patient's desire or need. The "Rule of Tens" can be applied in the emergency room to guide the surgeon's recommendations as well as expectations of response to treatment.

The external ring method of microvenous anastomosis: a new experimental concept.

A new method of microvenous anastomosis has been devised using a rigid ring around the anastomotic circumference. Only four sutures are used in the anastomosis and these are tied around the ring so as to stretch open the anastomotic site. The method has been tested in experimental rats and compared with the standard technique of anastomosis. The results and possible clinical implications of this method are discussed.

Digital replantation and amputation--comparison of function.

Clearer indications regarding when to replant an amputated digit can be obtained by comparing the functional capabilities of two similar groups of patients, one of which has had amputations and one of which has had replantations. This paper reports such a comparative study. Function was assessed by asking the patient to perform 10 tests designed to cover a broad spectrum of everyday activities, and grip strength was compared to that in a normal hand. Grip strength was appreciably greater in patients with replanted thumbs and multiple digits, and less so in those with replanted single digits. Based on our findings on the small, but intensively studied, number of patients assessed in this review, it would appear that thumbs should always be replanted if possible. In contrast, the functional analysis shows little necessity for replantation of a single finger. Multiple digital replantation assumes lesser functional value if one or more fingers remain that can oppose the thumb to provide prehension.
