ABOS Part I Comprehensive Review - Batch 68

Question 1

A 52-year-old male presents to the clinic 3 days after feeling a "pop" in his right elbow while lifting a heavy box. He reports immediate pain, followed by bruising and weakness. On examination, a palpable defect is noted in the distal arm, and he de

Accepted Answer

Inability to "hook" the distal biceps tendon

Question 2

A 48-year-old male undergoes a single-incision anterior repair for an acute distal biceps tendon rupture. During the procedure, the surgeon is meticulously dissecting through the subcutaneous tissue and fascia in the antecubital fossa.

Accepted Answer

Lateral Antebrachial Cutaneous Nerve (LACN)

Question 3

During a single-incision anterior repair of a distal biceps tendon rupture, the surgeon has retrieved the retracted tendon and is preparing the radial tuberosity for fixation. The image below depicts a surgical field during such a procedure.

Accepted Answer

Placing the forearm in full pronation and using a deep retractor laterally

Question 4

A 68-year-old sedentary male presents with a complete distal biceps tendon rupture sustained 8 weeks prior. He reports mild discomfort but states he can manage most daily activities without significant difficulty, as he primarily uses his left arm fo

Accepted Answer

Non-operative management with physical therapy

Question 5

A 42-year-old construction worker undergoes an acute single-incision anterior repair of a distal biceps tendon rupture. Postoperatively, he develops persistent numbness and dysesthesia along the radial aspect of his forearm. Physical examination conf

Accepted Answer

Lateral Antebrachial Cutaneous Nerve (LACN) injury

Question 6

A 38-year-old athlete undergoes a single-incision distal biceps tendon repair with cortical button fixation. According to the standard post-operative rehabilitation protocol described in the case, what is the most appropriate activity during the init

Accepted Answer

Passive elbow flexion from 30 to 90 degrees

Question 7

A 55-year-old male sustains a complete distal biceps tendon rupture. He opts for non-operative management due to personal preference and a sedentary lifestyle. Based on the biomechanical principles outlined in the case, what is the most significant f

Accepted Answer

Substantial loss of forearm supination strength

Question 8

A surgeon is discussing options for distal biceps tendon repair with a 40-year-old patient. The patient is concerned about potential complications, particularly heterotopic ossification (HO). Based on the literature review in the case, which statemen

Accepted Answer

The two-incision (Boyes-O'Brien) approach is associated with a higher incidence of HO.

Question 9

A surgeon is performing a distal biceps tendon repair. After retrieving the tendon, they note its unique twisted morphology. Which statement accurately describes the anatomical insertion of the biceps tendon fibers onto the radial tuberosity?

Accepted Answer

The short head fibers insert more distally and anteriorly, and the long head fibers insert more proximally and posteriorly.

Question 10

A 50-year-old active male presents 6 weeks after sustaining a complete distal biceps tendon rupture. He initially tried conservative management but now desires surgical repair due to persistent weakness impacting his work. MRI shows significant tendo

Accepted Answer

Increased technical difficulty, potentially requiring tendon lengthening or graft augmentation.
